For other uses, see Blindsight (disambiguation). Blindsight is the ability of people who are cortically blind due to lesions in their striate cortex, also known as primary visual cortex or V1, to respond to visual stimuli that they do not consciously see. [ 1] The majority of studies on blindsight are conducted on patients who have the conscious blindness on only one side of their visual field. Following the destruction of the striate cortex, patients are asked to detect, localize, and discriminate amongst visual stimuli that are presented to their blind side, often in a forced-response or guessing situation, even though they do not consciously recognize the visual stimulus. Research shows that blind patients achieve a higher accuracy than would be expected from chance alone. Type 1 blindsight is the term given to this ability to guess—at levels significantly above chance—aspects of a visual stimulus (such as location or type of movement) without any conscious awareness of any stimuli. Type 2 blindsight occurs when patients claim to have a feeling that there has been a change within their blind area—e.g. movement—but that it was not a visual percept. [ 2] Blindsight challenges the common belief that perceptions must enter consciousness to affect our behavior; showing that our behavior can be guided by sensory information of which we have no conscious awareness.

But a neuropsychologist named Elkhonon Goldberg at New York University School of Medicine, who wrote a fantastic book about frontal lobe functions called The Executive Brain, has a different theory. He thinks that while the frontal lobes may be more fragile, there is another factor involved, which is that every other part of the brain is connected to them. When you damage any part of the brain, you change input to the frontal lobes, and when you change input, you change output. If the frontal lobes aren't getting the right input, they don't produce the right output even though structurally they're fine. So all brain damage ends up looking like frontal lobe damage, whether the frontal lobes were injured or not. \"\" The orbital-frontal cortex and Phineas Gage: Updated 7/9/2011\"\"In primates, the frontal lobe has an important role in establishing priorities and planning,\"\" writes Allman in Evolving Brains. \"\" In particular, the lower surface of the frontal lobe, termed the orbital-frontal cortex, is especially important for these functions, as has been shown by an extraordinary series of clinical observations of brain-damaged patients by Antonio Damasio and his team in the Department of Neurology at the University of Iowa College of Medicine. \"\"" }, { "docid": "D2866198#0", "title": "https://courses.lumenlearning.com/wsu-sandbox/chapter/the-brain-and-spinal-cord/\nThe Brain and Spinal Cord", "text": "The Brain and Spinal Cord Learning Objectives By the end of this section, you will be able to: Explain the functions of the spinal cord Identify the hemispheres and lobes of the brain Describe the types of techniques available to clinicians and researchers to image or scan the brain The brain is a remarkably complex organ comprised of billions of interconnected neurons and glia.

In this section, we discuss the overall organization of the brain and the functions associated with different brain areas, beginning with what can be seen as an extension of the brain, the spinal cord. The Spinal Cord It can be said that the spinal cord is what connects the brain to the outside world. Because of it, the brain can act. The spinal cord is like a relay station, but a very smart one. It not only routes messages to and from the brain, but it also has its own system of automatic processes, called reflexes. The top of the spinal cord merges with the brain stem, where the basic processes of life are controlled, such as breathing and digestion.

It is also divided into left and right cerebral hemispheres by the longitudinal fissure, but the two hemispheres are joined at the midline by the corpus callosum. [ 1]At the cellular and circuit level, the cerebral cortex is characterized by two primary organizational features:across its surface it is divided into functional areas that serve various sensory, motor, and cognitive functions, andit is subdivided into several layers that organize the input and output connectivity of resident neurons. These two fundamental properties provide modular functionality. [ 1]In large mammals, the cerebral cortex is usually folded, providing a greater surface area in the confined volume of the cranium. Increased surface area is thought to be important because it allows for the addition and evolution of a greater diversity of functional modules, or areas.

Somatic senses inform the nervous system about the external environment, but the response to that is through voluntary muscle movement. The term “voluntary” suggests that there is a conscious decision to make a movement. However, some aspects of the somatic system use voluntary muscles without conscious control. One example is the ability of our breathing to switch to unconscious control while we are focused on another task. However, the muscles that are responsible for the basic process of breathing are also utilized for speech, which is entirely voluntary. Cortical Responses Let’s start with sensory stimuli that have been registered through receptor cells and the information relayed to the CNS along ascending pathways. In the cerebral cortex, the initial processing of sensory perception progresses to associative processing and then integration in multimodal areas of cortex. These levels of processing can lead to the incorporation of sensory perceptions into memory, but more importantly, they lead to a response. The completion of cortical processing through the primary, associative, and integrative sensory areas initiates a similar progression of motor processing, usually in different cortical areas." }, { "docid": "D133100#0", "title": "https://en.wikipedia.org/wiki/Motor_cortex\nMotor cortex", "text": "\"Motor cortex From Wikipedia, the free encyclopedianavigation search Motor Cortex Topography of human motor cortex Details Identifiers Latin cortex motorius Me SH D009044Neuro Names 2332Neuro Lex ID oen_0001104Anatomical terms of neuroanatomy [ edit on Wikidata]The motor cortex is the region of the cerebral cortex involved in the planning, control, and execution of voluntary movements.

The original design of this system is preserved across many animals through evolution; thus, adaptive physiological and behavioral functions are similar across many animal species. Comparative study of physiological functioning in the nervous systems of different animals lend insights to their behavior and their mental processing and make it easier for us to understand the human brain and behavior. In addition, studying the development of the nervous system in a growing human provides a wealth of information about the change in its form and behaviors that result from this change. The nervous system is divided into central and peripheral nervous systems, and the two heavily interact with one another. The peripheral nervous system controls volitional (somatic nervous system) and nonvolitional (autonomic nervous system) behaviors using cranial and spinal nerves. The central nervous system is divided into forebrain, midbrain, and hindbrain, and each division performs a variety of tasks; for example, the cerebral cortex in the forebrain houses sensory, motor, and associative areas that gather sensory information, process information for perception and memory, and produce responses based on incoming and inherent information.

Follow 3 answers Answers Relevance Rating Newest Oldest Best Answer: The cerebral cortex is connected to various subcortical structures such as the thalamus and the basal ganglia, sending information to them along efferent connections and receiving information from them via afferent connections. Most sensory information is routed to the cerebral cortex via the thalamus. Olfactory information, however, passes through the olfactory bulb to the olfactory cortex (piriform cortex). The vast majority of connections are from one area of the cortex to another rather than to subcortical areas; Braitenberg and Schüz (1991) put the figure as high as 99%. [ 15] The cortex is commonly described as comprising three parts: sensory, motor, and association areas. Sensory areas The sensory areas are the areas that receive and process information from the senses. Parts of the cortex that receive sensory inputs from the thalamus are called primary sensory areas. The senses of vision, audition, and touch are served by the primary visual cortex, primary auditory cortex and primary somatosensory cortex.

We have already seen that the sudden increase in structural complexity is accompanied by a dramatic increase in physiological complexity. In the cortex we find a greater variety of physiologically defined cell types, and the cells respond to more elaborate stimuli, especially to a greater number of stimulus parameters that have to be properly specified. We are concerned not only with stimulus position and spot size, as we are in the retina and geniculate, but now suddenly with line orientation, eye dominance, movement direction, line length, and curvature. What if anything is the relation between these variables and the structural organization of the cortex? To address this question, I will need to begin by saying something about the structure of the striate cortex. ANATOMY OF THE VISUAL CORTEX The cerebral cortex, which almost entirely covers the cerebral hemispheres, has the general form of a plate whose thickness is about 2 millimeters and whose surface area in humans is over i square foot. The total area of the macaque monkey's cortex is much less, probably about one-tenth that of the human. We have known for over a century that this plate is subdivided into a patchwork of many different cortical areas; of these, the primary visual cortex was the first to be distinguished from the rest by its layered or striped appearance in cross section—hence its classical name, striate cortex. At one time the entire careers of neuroanatomists consisted of separating off large numbers of cortical areas on the basis of sometimes subtle histological distinctions, and in one popular numbering system the striate cortex was assigned the number 17." }, { "docid": "D1593258#0", "title": "http://medical-dictionary.thefreedictionary.com/area\narea", "text": "area Also found in: Dictionary, Thesaurus, Legal, Financial, Acronyms, Idioms, Encyclopedia, Wikipedia.

It may be used in people who have symptoms such as delusions, hallucinations, or suicidal thoughts or when other treatments such as psychotherapy and antidepressant medicines have not worked. It is also used for other psychiatric and neurological conditions, such as schizophrenia and Parkinson's disease. Before ECT, you are given anesthesia to put you in a sleepy state, and you are given medicines to relax your muscles. Then an electrical current is briefly sent to the brain through electrodes placed on the temples or elsewhere on the head, depending on the condition and type of ECT. The electrical stimulation, which lasts up to 8 seconds, produces a short seizure. Because of anesthesia, the seizure activity related to ECT does not cause the body to convulse. It is not known exactly how this brain stimulation helps treat depression. ECT probably works by altering brain chemicals (similarly to medicines), including neurotransmitters like serotonin, natural pain relievers called endorphins, and catecholamines such as adrenaline. ECT treatments are usually done 2 to 3 times a week for 2 to 3 weeks." } ]

When these have taken full effect, the patient's brain is stimulated, using electrodes placed at precise locations on the patient's head, with a brief controlled series of electrical pulses. This stimulus causes a seizure within the brain which lasts for approximately a minute. Because of the muscle relaxants and anesthesia, the patient's body does not convulse and the patient feels no pain.

The treatments were unpleasant and dangerous. They were given without anesthesia. The ICT mortality rate varied from 1% to 10% of patients treated. Prolonged coma, in which the patient did not respond to the administration of glucose, was a constant threat. ECT was safer, with lower mortality rates, but patients suffered fractures, severe memory loss, and spontaneous seizures.

Major depressive disorder is a common mental disorder that can negatively affect many areas of someone’s life. It impacts mood and behavior as well as various physical functions, including appetite and sleep. People with major depression often lose interest in activities they once enjoyed and have trouble performing everyday activities. Occasionally, they may even feel as if life isn’t worth living. It’s estimated that about 20 percent of people with major depression also have symptoms of psychosis. This combination is sometimes referred to as psychotic depression.

Only a few realized that individuals with mental illnesses should be treated humanely rather than exorcised, punished, or banished. Certain Greek medical writers, however, notably Hippocrates (flourished 400 bce ), regarded mental disorders as diseases to be understood in terms of disturbed physiology. He and his followers emphasized natural causes, clinical observation, and brain pathology. Later Greek medical writers, including those who practiced in imperial Rome, prescribed treatments for mental illness, including a quiet environment, work, and the use of drugs such as the purgative hellebore. It is probable that most people with psychoses during ancient times were cared for by their families and that those who were thought to be dangerous to themselves or others were detained at home by relatives or by hired keepers. Hippocrates, Roman bust copied from a Greek original, c. 3rd century bce; in the collection of the Antichità di Ostia, Italy. Courtesy of the Soprintendenza alle Antichità di Ostia, Italy During the early Middle Ages in Europe, primitive thinking about mental illness reemerged, and witchcraft and demonology were invoked to account for the symptoms and behaviour of people with psychoses. At least some of those who were deemed insane were looked after by the religious orders, who offered care for the sick generally. The empirical and quasi-scientific Greek tradition in medicine was maintained not by the Europeans but by the Muslim Arabs, who are usually credited with the establishment of asylums for the mentally ill in the Middle East as early as the 8th century." }, { "docid": "D495700#0", "title": "http://www.mayoclinic.org/tests-procedures/electroconvulsive-therapy/basics/definition/PRC-20014161\nOverview", "text": "Overview Electroconvulsive therapy (ECT) is a procedure, done under general anesthesia, in which small electric currents are passed through the brain, intentionally triggering a brief seizure. ECT seems to cause changes in brain chemistry that can quickly reverse symptoms of certain mental illnesses. ECT often works when other treatments are unsuccessful and when the full course of treatment is completed, but it may not work for everyone. Much of the stigma attached to ECT is based on early treatments in which high doses of electricity were administered without anesthesia, leading to memory loss, fractured bones and other serious side effects. ECT is much safer today. Although ECT still causes some side effects, it now uses electric currents given in a controlled setting to achieve the most benefit with the fewest possible risks. Why it's done Electroconvulsive therapy (ECT) can provide rapid, significant improvements in severe symptoms of several mental health conditions. ECT is used to treat: Severe depression, particularly when accompanied by detachment from reality (psychosis), a desire to commit suicide or refusal to eat.

Critics call it by its old name: electroshock. They claim that it temporarily \"\"lifts\"\" depression by causing transient personality changes similar to those seen in head injury patients: euphoria, confusion and memory loss. Both camps agree that ECT, which is administered annually to an estimated 100,000 Americans, most of them women, is a simple procedure -- so simple that an ad for the most widely used shock machine tells doctors they need only set a dial to a patient's age and press a button. Electrodes connected to an ECT machine, which resembles a stereo receiver, are attached to the scalp of a patient who has received general anesthesia and a muscle relaxant. With the flip of a switch the machine delivers enough electricity to power a light bulb for a fraction of a second.

Transcranial magnetic stimulation (TMS) is a form of brain stimulation, which reorganizes a brain's dysfunctional neural circuitry to the benefit of the patient. It's currently being used for people suffering from depression that is treatment-resistant—meaning it doesn't respond to the first-line approaches including lifestyle changes, psychotherapy, and antidepressant medications, but it is being studied for other uses, too. One big appeal: Unlike medications, it specifically hits the brain instead of the whole body So it is also offers an intriguing possible treatment for postpartum depression in women, say, who are breastfeeding and don't want their babies to be exposed to drugs. To deliver TMS, a clinician presses a device to the patient's head to deliver magnetic pulses that reach about an inch deep inside the skull, causing electrical changes in targeted neurons. Typically, a TMS patient goes through a series of about half-hour treatments, usually several times per week over the course of a few weeks or maybe a month. But the results are temporary and may only last weeks or months; patients may need to return for an additional series of treatments if symptoms return.

D. ~ 2 min read Electroconvulsive Therapy — or ECT as it’s commonly known — is a brief medical procedure that involves applying short electrical bursts to the brain through external electrode pads on your head. These electrical bursts create a seizure, which has been shown to help relieve symptoms associated with severe depression. The entire procedure lasts about 15 minutes, although you may be in the hospital for about an hour to include time for prep and recovery from the treatment. ECT treatments are usually grouped together in 6 to 12 treatments at a time, generally given three times a week for 2 to 4 weeks. The number of treatments you will need depends on the severity of your symptoms and how rapidly they improve. Before your first ECT treatment, your doctor needs to make sure the procedure is safe for you. Your psychiatrist will likely refer you to a physician for a physical examination, an electrocardiogram (ECG) to check your heart’s health, and laboratory tests (basic blood tests), to ensure there are no medical conditions that would preclude you from receiving ECT treatment. You may also be referred to an anesthesiologist to go over the risks associated with having anesthesia. Modern electroconvulsive therapy is administered under general anesthesia, to ensure it is a safe and pain-free experience. You will therefore be unconscious during the treatment." }, { "docid": "D556284#0", "title": "http://www.webmd.com/depression/news/20030619/memory-loss-common-complaint-with-ect\nMemory Loss Common Complaint With ECT", "text": "\"Memory Loss Common Complaint With ECTBut Defenders Say Electroconvulsive Therapy Still the Best Option for Some Depression By Salynn Boyles From the Web MD Archives June 19, 2003 -- Supporters say the controversial treatment called electroconvulsive therapy (ECT) helps severely depressed patients who have few other medical options, but new research concludes that this help may come at a high price.

A retrospective study conducted by investigators at Captain James Lovell Federal Health Care Center (FHCC) – Rosalind Franklin University of Medicine and Science in North Chicago, Illinois, showed that among patients with PTSD and major depressive disorder (MDD), the death rate among those who did not receive ECT was significantly greater than that of their counterparts who received ECT.

This acute episode is the focus of initial treatment. Depending on the severity, bipolar treatment options may include hospitalization, particularly if harm to the patient or those around him or her is a concern. The goal of acute bipolar disorder treatment is to rapidly stabilize the condition enough to get the patient out of danger and move forward into a long-term bipolar treatment plan. Typically this means treating the episode with the appropriate bipolar medication and scheduling follow-up sessions with a psychiatrist, psychotherapist and/or case manager. Medication Treatment of Bipolar Disorder Both acute manic or depressive episodes, as well as long-term bipolar treatment, typically require the use of medications. Medications for bipolar disorder vary depending on the phase of the illness: acute mania, acute depression or long-term treatment. 1 Medication selection is also based on specific symptoms and severity. Common medications used in the treatment of bipolar disorder include: Antipsychotics such as haloperidol (Haldol), ziprasidone (Geodon), quetiapine (Seroquel) and risperidon (Risperdal)Lithium Anticonvulsants (often called mood stabilizers) like Valproate (Depakote) and lamotrigine (Lamictal)Benzodiazepines such as clonazepam (Klonopin) and lorazepam (Ativan)Antidepressants may be prescribed, but only with additional mood stabilizing medication. Most doctors agree, antidepressants should be used with caution in the treatment of bipolar disorder due to the possibility of inducing mania or rapid-cycling.

Brain stimulation therapies involve activating or inhibiting the brain directly with electricity. The electricity can be given directly by electrodes implanted in the brain, or noninvasively through electrodes placed on the scalp. The electricity can also be induced by using magnetic fields applied to the head. While these types of therapies are less frequently used than medication and psychotherapies, they hold promise for treating certain mental disorders that do not respond to other treatments. Electroconvulsive therapy is the best studied brain stimulation therapy and has the longest history of use. Other stimulation therapies discussed here are newer, and in some cases still experimental methods. These include:vagus nerve stimulation (VNS)repetitive transcranial magnetic stimulation (r TMS)magnetic seizure therapy (MST)deep brain stimulation (DBS)A treatment plan may also include medication and psychotherapy.

Electroconvulsive Therapy Definition Electroconvulsive therapy (ECT) is a medical treatment for severe mental illness in which a small, carefully controlled amount of electricity is introduced into the brain. This electricalstimulation, used in conjunction with anesthesia and muscle relaxant medications, produces a mild generalized seizure or convulsion. While used to treat a variety of psychiatric disorders, it is most effective in the treatment of severe depression, and provides the most rapid relief currentlyavailable for this illness. Purpose The purpose of electroconvulsive therapy is to provide relief from the signs and symptoms of mental illnesses such as severe depression, mania, and schizophrenia. ECT is indicated whenpatients need rapid improvement because they are suicidal, self-injurious, refuse to eat or drink,cannot or will not take medication as prescribed, or present some other danger to themselves. Antidepressant medications, while effective in many cases, may take two-six weeks to produce a therapeutic effect.

Irritable bowel syndrome is a functional gastrointestinal (GI) disorder, meaning it is a problem caused by changes in how the GI tract works. Children with a functional GI disorder have frequent symptoms, but the GI tract does not become damaged. IBS is not a disease; it is a group of symptoms that occur together. The most common symptoms of IBS are abdominal pain or discomfort, often reported as cramping, along with diarrhea, constipation, or both. In the past, IBS was called colitis, mucous colitis, spastic colon, nervous colon, and spastic bowel. The name was changed to reflect the understanding that the disorder has both physical and mental causes and is not a product of a person’s imagination. IBS is diagnosed when a child who is growing as expected has abdominal pain or discomfort once per week for at least 2 months without other disease or injury that could explain the pain. The pain or discomfort of IBS may occur with a change in stool frequency or consistency or may be relieved by a bowel movement.

Silver, November 2008Question: Help! my dog has diarrhea—is there anything in my medicine cabinet or on my kitchen shelf that could be used to save both of us a visit to the vet? Answer: As a veterinarian, this author sees many patients with minor problems (such as the dog in this story) who could be treated at home safely and effectively. At the same time, there are dogs whose problems, if not addressed early enough by a veterinary professional, suffer more than they need to. Probably the most common complaint received by veterinarians is that of diarrhea. It’s such an easy condition to identify: The smell is unmistakable, as is its chocolate-pudding appearance. Most of the time, diarrhea is caused by a dietary indiscretion or stressful circumstances, and is self-limiting. Diarrhea is not a disease; rather, it is a symptom of a dysfunction of the gastrointestinal tract (GIT). When associated with bad food or food-borne pathogens, diarrhea serves to rapidly remove pathogens from the GIT before they have a chance to be absorbed and cause more damage. Warning Signs That Diarrhea Needs Medical Attention • Black, tarry stool, or stool with copious amounts of fresh blood (bright red)• Loss of appetite• Marked lethargy• Frequent vomiting• Signs of abdominal pain ( bloating, groaning, panting rapidly or avoidance response when belly is touched)• Lasts longer than 48 hours (Since it can rapidly weaken puppies and geriatrics, or dogs with chronic diseases, they may need veterinary attention sooner. )" }, { "docid": "D1948726#0", "title": "http://beingstray.com/canine-stools-diarrhea/\nWhat Canine Stools Tell You About Diarrhea", "text": "What Canine Stools Tell You About Diarrhea By isak, June 10, 2009Diarrhea is the passage of loose, unformed stools generally occurring in more frequent bowel movements.

Chronic diarrhea often comes on gradually and persists for three weeks or longer, or has an episodic pattern of recurrence. Chronic diarrhea requires veterinary investigation.

[ 3] Sometimes, different alleles can result in different observable phenotypic traits, such as different pigmentation. A notable example of this trait of color variation is Gregor Mendel's discovery that the white and purple flower colors in pea plants were the result of \"\"pure line\"\" traits which could be used as a control for future experiments. However, most genetic variations result in little or no observable variation. The word \"\"allele\"\" is a short form of allelomorph (\"\"other form\"\", a word coined by British geneticists William Bateson and Edith Rebecca Saunders ), [4] [5] which was used in the early days of genetics to describe variant forms of a gene detected as different phenotypes. It derives from the Greek prefix ἀλλήλ, allel, meaning \"\"reciprocal\"\", or \"\"each other\"\", which itself is related to the Greek adjective ἄλλος, allos (cognate with Latin alius ), meaning \"\"other\"\". Most multicellular organisms have two sets of chromosomes; that is, they are diploid. These chromosomes are referred to as homologous chromosomes.

In 1930, he belatedly received the Nobel Prize for his discovery of blood types. All humans and many other primates can be typed for the ABO blood group. There are four principal types: A, B, AB, and O. There are two antigens and two antibodies that are mostly responsible for the ABO types. The specific combination of these four components determines an individual's type in most cases.

However, an individual with this rare blood phenotype cannot receive blood from these people. Why? There are four blood groups in the ABO system - A, B, AB, and O, and classification is based on the presence or absence of antigenic substances that appear on the surface of blood cells. Both parents contribute to a child's blood type and the alleles that contribute to this are O, A, and B. Knowing the blood phenotypes of a couple, a person is able to predict the blood type of their child using the Punnet square. For example, if a blood type BO woman has a child with a man who is blood type O or at least carries an O allele (AO, BO, or OO genotypes) then they could have a blood type O child. However, there are rare instances when a couple produces a type O child even if they don’t possess any O allele. If this situation occurs, the child possibly carries the Bombay blood type, a blood type first discovered among three unrelated individuals in Bombay (now Mumbai) India in 1952 by Dr. Bhende and his colleagues. The major characteristic of the red blood cells of the Bombay blood group is the absence of the H antigen.

The term haemolytic disease means that red blood cells are broken down more quickly than usual which can cause jaundice, anaemia and in very severe cases can cause death. During pregnancy, this breakdown of red blood cells in the baby may occur if the mother and baby’s blood types are incompatible and if these different blood types come into direct contact with each other and antibodies are formed. Significant problems with ABO incompatibility occur mostly with babies whose mothers have O blood type and where the baby is either A or B blood type. Premature babies are much more likely to experience severe problems from ABO incompatibility, while healthy full term babies are generally only mildly effected. Unlike haemolytic disease that can result in subsequent babies when a mother has a negative blood group, ABO incompatibility can occur in first-born babies and does not become more severe in further pregnancies. To help you understand ABO incompatibility, it is helpful to review the different blood groups. The genes you inherit from your parents determine your blood group. There are four blood types; A, B, AB and O. Each blood type has its own individual collection of chemicals on the blood cell surface known as antigens, so type A has the A antigen, B has the B antigen, AB has both antigens and O contains no antigen. If different blood types mix, an immune response occurs and the person will produce antibodies to attack the foreign blood antigen." }, { "docid": "D1493835#0", "title": "http://facstaff.uwa.edu/jmccall/evolution_of_the_human.htm\nThe purpose of this web page is to explain some basic facts about human ABO blood group system and to summarize the research and hypotheses regarding its evolution.", "text": "\"EVOLUTION OF THE HUMANABO BLOOD GROUP SYSTEMBonnie B.

BACKGROUNDThe ABO System -- A Polymorphism (http://www.bayerpharma-na.com/children/RON/circu/chrc.0103.asp)Humans can have blood types A, B, AB, or O. This is known as the ABO blood group system, and it is a polymorphism . A polymorphism is defined as a \"\"genetic locus with two or more alleles that occur in appreciable (>1%) frequency in a given population\"\" (http://www.as.ua.edu). The ABO blood group system was the first polymorphism discovered in humans. It is however only one of MANY systems involving the red blood cells. Antibodies and Antigens Understanding the difference between antibodies and antigens is essential to understanding the ABO blood group system and its evolution. Antibodies are substances produced by the body when it is invaded and act to protest it from the foreign substance. Antigens are found in the invading substance and elicit the production of antibodies. The two substances, thus, work in conjunction with each other. ( http://www.uen.org/utahlink/activities/view activity.cgi?activity ld=3037)Typically, the body does not produce antibodies until AFTER it has been introduced to a new substance." }, { "docid": "D2089233#0", "title": "http://livehealthy.chron.com/can-type-o-blood-given-anyone-10193.html\nWhy Can Type O Blood Be Given to Anyone?", "text": "\"Related Articles1 [RH- Blood] | What Happens if a Mother Has an RH- Blood Type & the Fetus Has an RH+ Blood Type?2 [Could Cause] | What Could Cause Blood in the Stool & Sharp Stomach Pains?3 [Wrong Blood] | What Happens When You Give Someone the Wrong Blood Type?4 [Blood Pressure] | What Is Extremely High Blood Pressure?

Mendel observed that a heterozygote offspring can show the same phenotype as the parent homozygote, so he concluded that there were some traits that dominated over other inherited traits. However, the relationship of genotype to phenotype is rarely as simple as the dominant and recessive patterns described by Mendel. As the study of inheritance expanded beyond the seven traits Mendel initially examined and also included organisms other than pea plants, biologists began to notice a variety of relationships between alleles that code for the same trait. These allelic interactions were not exclusively recessive or dominant, and they greatly enriched our understanding of how genotype leads to phenotype. Complete versus Partial Dominance Figure 1Figure Detail Dominance affects the phenotype derived from an organism 's genes, but it does not affect the way these genes are inherited. Complete dominance occurs when the heterozygote phenotype is indistinguishable from that of the homozygous parent. However, sometimes the heterozygote displays a phenotype that is an intermediate between the phenotypes of both homozygote parents (one of which is homozygous dominant, and the other of which is homozygous recessive). This intermediate phenotype is a demonstration of partial or incomplete dominance. When partial dominance occurs, a range of phenotypes is usually observed among the offspring." }, { "docid": "D2529146#0", "title": "http://www.bloodbook.com/rare.html\nRARE BLOOD TYPESBLOODBOOK.COM", "text": "\"RARE BLOOD TYPESBLOODBOOK.

Human blood type is determined by the presence or absence of certain identifiers on the surface of red blood cells. These identifiers, also called antigens, help the body's immune system to recognize it's own red blood cell type. There are four main ABO blood type groupings: A, B, AB, and O. These blood groups are determined by the antigen on the blood cell surface and the antibodies present in the blood plasma. Antibodies (also called immunoglobulins) are specialized proteins that identify and defend against foreign intruders to the body. Antibodies recognize and bind to specific antigens so that the foreign substance can be destroyed. Antibodies in an individual's blood plasma will be different from the antigen type present on the red blood cell surface. For example, a person with type A blood will have A antigens on the blood cell membrane and type B antibodies (anti-B) in the blood plasma. ABO Blood Types ABO blood group antigens present on red blood cells and Ig M antibodies present in the serum.

Beriberi is a disease caused by a vitamin B-1 deficiency, also known as thiamine deficiency. There are two types of the disease: wet beriberi and dry beriberi. Wet beriberi affects the heart and circulatory system. In extreme cases, wet beriberi can cause heart failure. Dry beriberi damages the nerves and can lead to decreased muscle strength and eventually, muscle paralysis. Beriberi can be life-threatening if it isn’t treated. If you have access to foods rich in thiamine, your chances of developing beriberi are low. Today, beriberi mostly occurs in people with an alcohol use disorder. Beriberi from other causes are rare in the United States." } ]

Basic Description Role in Health Support Summary of Food Sources Nutrient Rating Chart Impact of Cooking, Storage and Processing Risk of Dietary Deficiency Other Circumstances that Might Contribute to Deficiency Relationship with Other Nutrients Risk of Dietary Toxicity Disease Checklist Public Health Recommendations References Basic Description Vitamin B1, also known as thiamin, is classified as a B-complex vitamin. Very small amounts of vitamin B1 are found in virtually all foods, and many commonly eaten foods contain substantial amounts. For example, 50/100 of our WHFoods rank as good, very good, or excellent sources of B1. In this context, it might seem odd that deficiency of vitamin B1 is among the more common nutrient deficiencies in the U. S. Yet there is a very simple reason for this high risk of deficiency despite the widespread availability of vitamin B1 in foods, and that reason is food processing. Vitamin B1 is among the nutrients most prone to destruction by our modern food production system. At each step along the way, from storage though refining up through cooking, we lose a big portion of the vitamin B1 content of foods. We'll detail this more in the Impact of Cooking, Storage, and Processing section below. For these reasons, vitamin B1 makes a good case study for the wisdom of the World's Healthiest Foods approach of minimal processing and low impact cooking techniques. Of the foods listed on our site, we have one excellent source of vitamin B1 (asparagus), 10 very good sources, and 39 good sources." }, { "docid": "D1115829#0", "title": "http://www.mayomedicallaboratories.com/test-catalog/Clinical+and+Interpretive/42356\nUseful For", "text": "Useful For Assessment of thiamine deficiency Thiamine measurement in patients with behavioral changes, eye signs, gait disturbances, delirium, and encephalopathy; or in patients with questionable nutritional status, especially those who appear at risk and who also are being given insulin for hyperglycemia Clinical Information Thiamine (vitamin B1) is an essential vitamin required for carbohydrate metabolism, brain function, and peripheral nerve myelination. Thiamine is obtained from the diet. Body stores are limited and deficiencies can develop quickly. The total thiamine pool in the average adult is about 30 mg. An intake of 0.5 mg per 1,000 kcal per day is needed to maintain this pool. Due to its relatively short storage time, marginal deficiency can occur within 10 days and more severe deficiency within 21 days if intake is restricted. Approximately 80% of all chronic alcoholics are thiamine deficient due to poor nutrition. However, deficiency also can occur in individuals who are elderly, have chronic gastrointestinal problems, have marked anorexia, are on cancer treatment, or are receiving diuretic therapy. The signs and symptoms of mild-to-moderate thiamine deficiency are nonspecific and may include poor sleep, malaise, weight loss, irritability, and confusion. Newborns breast fed from deficient mothers may develop dyspnea and cyanosis; diarrhea, vomiting, and aphonia may follow." }, { "docid": "D640416#0", "title": "http://www.livestrong.com/article/274311-list-of-vitamin-deficiency-diseases/\nList of Vitamin Deficiency Diseases", "text": "List of Vitamin Deficiency Diseasesby MARTIN HUGHES Oct. 03, 2017Numerous diseases are associated with vitamin deficiency. According to the World Health Organization, or WHO, micronutrient deficiencies, including vitamin deficiencies, can affect anybody, although young children and pregnant women in certain developing nations are more commonly affected than others. Vitamin deficiency may be caused by an unhealthy diet, starvation or certain medical conditions that make absorbing nutrients difficult. Symptoms associated with vitamin deficiency diseases vary based on the disease and its severity.

According to the Medline Plus website, pellagra occurs when a person fails to get sufficient amounts of niacin, or vitamin B3, or tryptophan. Tryptophan is one of 20 standard amino acids. Niacin is a water-soluble B vitamin that assists the digestive system, skin and nerves. The most common cause of pellagra is insufficient amounts of niacin or tryptophan in the diet.

Thiamine is mostly concentrated in the skeletal muscles. It is also found in the heart, liver and kidneys. Thiamine is excreted through the kidney. Causes and Risk Factors Beriberi is mostly found in developing countries where people may not be able to access a diet rich in vitamin B1." }, { "docid": "D932081#0", "title": "http://www.virtualmedstudent.com/links/nutrition/vitaminB1.html\nVitamin B1 (aka: thiamine)", "text": "\"Vitamin B1 (aka: thiamine)Function and Biochemistry || Role in Disease || Diagnosis || Overview || Related Articles || References and Resources || Leave a Comment || Search Function and Biochemistry Tweet Vitamin B1 (thiamine) and its derivatives serve many roles in the body. It functions primarily as a cofactor to help enzymes perform their molecular reactions. Several well known biochemical reactions in which thiamine plays a crucial component include: (1) Conversion of pyruvate to acetyl-Co A. (2) Conversion of α-ketoglutarate to succinyl-Co A in the Krebs cycle. ( 3) Conversion of glyceraldehyde-3-phosphate to ribose-5-phosphate. ( 4) It is used by the enzyme branched-chain α-keto acid dehydrogenase. All of these reactions are crucial to human biochemistry. The conversion of pyruvate to acetyl-Co A feeds important molecules into the Krebs cycle, which allows the cell to produce energy. The conversion of α-ketoglutarate to succinyl-Co A is necessary for the Krebs cycle to continue \"\"spinning\"\". Without vitamin B1 (thiamine) the cycle would slow causing decreased energy production.

If it is in alcoholic patients, they will need to discontinue consumption of the alcohol as well. Beriberi is caused by a deficiency of thiamine (Vit. B1). It can be a dietary-related deficiency or in some people (alcoholics and alcohol abusers) it is a problem with the body's ability to take in the vitamin from foods and/or store it. Today's diets in the developed nations are mostly supplemented with enough thiamine to prevent it in otherwise healthy people. It is still seen in under developed countries with diets lacking in proper nutrients. It causes heart and nervous system symptoms.25 people found this useful Was this answer useful?" }, { "docid": "D1926320#0", "title": "http://www.mnwelldir.org/docs/history/vitamins.htm\n.", "text": "\"The History of Vitamins (and a short history of scurvy, beriberi, and pellagra)Our knowledge of the chemical composition of vitamins and their importance in nutrition is relatively young, whereas the history of vitamin deficiencies goes back centuries. Scurvy is probably the first illness to be recognized (though not right away, as you will see) as a nutritional deficiency disorder. Its main symptom is massive hemorrhaging; one’s arteries, lacking sufficient vitamin C begin to pit and then finally break open causing internal hemorrhaging. Prior to this, the individual feels exhausted and weak, his gums start to bleed, and diarrhea sets in. Death was far too common the final result. ( For more on vitamin C and its connection to arterial health, you might wish to order our book, Bypassing Bypass . ) Hippocrates first described scurvy as bleeding gums, hemorrhaging and death in the 5th century BC. Outbreaks of scurvy were reported in 1500 BC Egypt, during the winters when fresh produce was scarce. In 1250, during the Crusades, rampant scurvy forced the retreat and eventual capture of St. Louis and his knights.

Thiamine deficiency causes a condition known as beriberi or beri-beri. The initial symptoms are very vague. The first indication of thiamine deficiency may be simple fatigue. As the condition becomes more advanced, there is a wide range of symptoms, affecting many organ systems. These include, but are not limited to chest pains, memory loss, muscle cramps and weakness. In more advanced cases, muscle atrophy and heart failure may be present. Purpose Thiamin has several important functions. It works with other B-group vitamins to help release energy from the food we eat and it keeps nerves and muscle tissue healthy. In the form of thiamin pyrophosphate (TPP), it plays an essential role as a cofactor in key reactions breaking down food and converting carbohydrate into energy for the body (carbohydrate metabolism)." }, { "docid": "D29879#0", "title": "https://en.wikipedia.org/wiki/Thiamine\nThiamine", "text": "\"From Wikipedia, the free encyclopedianavigation search Not to be confused with Thymine.

Vitamin deficiency occurs when there is insufficient or poor dietary intake of essential vitamins. Inadequate levels of vitamins may result in an array of miserable conditions and make the body feeble and vulnerable to many diseases. Types of Vitamin Deficiency Vitamin deficiency can be classified into two types: Primary Deficiency Primary deficiency is when an inadequate vitamin intake causes a person to become deficient. It is due to not receiving the necessary levels of a vitamin from your diet and this type is basic; it can be easily cured by adopting a special vitamin diet or taking vitamin supplements. Secondary Deficiency When a deficiency occurs as a result of a disease or lifestyle factor, this is called secondary deficiency. For example, smokers need to increase their intake of vitamin C by 30-50%. Another example is when someone’s lifestyle causes them to get minimal sun exposure which cause a deficiency in their vitamin D levels. This deficiency can affect the calcium absorption needed for healthy bones.

J. D. Novak Summary The vitamins were discovered in the span of only five decades commencing at the end of the nineteenth century. This was the result of observations by many people of relationships between diet and health in ways that were not explained by germ theory. Early observations based on the differential physical characteristics of bioactive component of foods gave rise to refinements afforded by a variety of experimental animal models with increasing definition of diet composition. This produced a zig-zag course of discovery that ultimately moved nutrition research to an activity reliant on hypothesis testing through experimentation. By the mid-twentieth century, 13 groups of vitamins were recognized and compositional information was available for use in the formulation of healthful diets for humans and animals. Anchoring Concepts1. A scientific theory is a plausible explanation for a set of observed phenomena; because theories cannot be tested directly, their acceptance relies on a preponderance of supporting evidence.2. A scientific hypothesis is a tentative supposition that is assumed for the purposes of argument or testing, and is thus used in the generation of evidence by which theories can be evaluated.3. An empirical approach to understanding the world involves the generation of theories strictly by observation, whereas an experimental approach involves the undertaking of operations (experiments) to test the truthfulness of hypotheses.4." }, { "docid": "D1324747#0", "title": "http://wikieducator.org/Carbohydrates,_Proteins,_Vitamins_and_Minerals\nCarbohydrates, Proteins, Vitamins and Minerals", "text": "\"Carbohydrates, Proteins, Vitamins and Minerals By Dr. Mohd.

These are carbohydrates, proteins, fats, vitamins, minerals, fiber and water. It is important to consume these seven nutrients on a daily basis to build and maintain health. Deficiencies, excesses and imbalances in diet can produce negative impacts on health, which may lead to diseases such as cardiovascular disease, diabetes, scurvy, obesity, or osteoporosis as well as psychological and behavioral problems. According to the reports of the United Nations World Health Organization (WHO: 1996), more than starvation the real challenge in developing nations today is malnutrition-the deficiency of micronutrients (vitamins, minerals and essential amino acids) that no longer allows the body to ensure growth and maintain its vital functions.

The most basic cause is simply a person not consuming foods with enough Vitamin B1, however this is rare in first world countries. Problems with the absorption of Vitamin B1 Thiamine in the small intestines can also result in a deficiency. One of the most common reasons this happens is consuming too much alcohol, however, there are a number of diseases that can result in a condition where Thiamine is not absorbed correctly. Symptoms related to low levels of energy in the person are the most common since energy production in the cells requires vitamin B1. The proper functioning of brain cells requires large amounts of energy making the effects quite dramatic and very visible when normal brain functioning is impaired by a lack of energy. Symptoms of Vitamin B1 Thiamine Deficiency Vitamin B1 deficiency has a number of basic symptoms associated with it. Supplementation or an increase in vitamin B1 nutritional levels can typically reverse the symptoms quickly. The initial stages of cellular starvation are the cause of most symptoms.
