Pappataci fever is prevalent in the subtropical zone of the Eastern Hemisphere between 20°N and 45°N, particularly in Southern Europe, North Africa, the Balkans, Eastern Mediterranean, Iraq, Iran, Pakistan, Afghanistan and India.The disease is transmitted by the bites of phlebotomine sandflies of the Genus Phlebotomus, in particular, Phlebotomus papatasi, Phlebotomus perniciosus and Phlebotomus perfiliewi. The sandfly becomes infected when biting an infected human in the period between 48 hours before the onset of fever and 24 hours after the end of the fever, and remains infected for its lifetime. Besides this horizontal virus transmission from man to sandfly, the virus can be transmitted in insects transovarially, from an infected female sandfly to its offspring.Pappataci fever is seldom recognised in endemic populations because it is mixed with other febrile illnesses of childhood, but it is more well-known among immigrants and military personnel from non-endemic regions.

Question: Does an infection for Sandflies go away over time?
Answer: remains infected for its lifetime
Collenchyma cells – collenchyma cells are alive at maturity and have thickened cellulosic cell walls. These cells mature from meristem derivatives that initially resemble parenchyma, but differences quickly become apparent. Plastids do not develop, and the secretory apparatus (ER and Golgi) proliferates to secrete additional primary wall. The wall is most commonly thickest at the corners, where three or more cells come in contact, and thinnest where only two cells come in contact, though other arrangements of the wall thickening are possible. Pectin and hemicellulose are the dominant constituents of collenchyma cell walls of dicotyledon angiosperms, which may contain as little as 20% of cellulose in Petasites. Collenchyma cells are typically quite elongated, and may divide transversely to give a septate appearance. The role of this cell type is to support the plant in axes still growing in length, and to confer flexibility and tensile strength on tissues. The primary wall lacks lignin that would make it tough and rigid, so this cell type provides what could be called plastic support – support that can hold a young stem or petiole into the air, but in cells that can be stretched as the cells around them elongate. Stretchable support (without elastic snap-back) is a good way to describe what collenchyma does. Parts of the strings in celery are collenchyma.

Question: What is the name of a type of string that constitutes parts of celery?
Answer: collenchyma
Parenchyma cells are living cells that have  functions ranging from storage and support to photosynthesis (mesophyll cells) and phloem loading (transfer cells). Apart from the xylem and phloem in their vascular bundles, leaves are composed mainly of parenchyma cells. Some parenchyma cells, as in the epidermis, are specialized for light penetration and focusing or regulation of gas exchange, but others are among the least specialized cells in plant tissue, and may remain totipotent, capable of dividing to produce new populations of undifferentiated cells, throughout their lives. Parenchyma cells have thin, permeable primary walls enabling the transport of small molecules between them, and their cytoplasm is responsible for a wide range of biochemical functions such as nectar secretion, or the manufacture of secondary products that discourage herbivory. Parenchyma cells that contain many chloroplasts and are concerned primarily with photosynthesis are called chlorenchyma cells. Others, such as the majority of the parenchyma cells in potato tubers and the seed cotyledons of legumes, have a storage function.

Question: What are made up almost entirely of parenchyma cells?
Answer: leaves
Phloem is a specialised tissue for food transport in higher plants, mainly transporting sucrose along pressure gradients generated by osmosis, a process called translocation. Phloem is a complex tissue, consisting of two main cell types, the sieve tubes and the intimately associated companion cells, together with parenchyma cells, phloem fibres and sclereids. Sieve tubes are joined end-to-end with perforate end-plates between known as sieve plates, which allow transport of photosynthate between the sieve elements. The sieve tube elements lack nuclei and ribosomes, and their metabolism and functions are regulated by the adjacent nucleate companion cells. The companion cells, connected to the sieve tubes via plasmodesmata, are responsible for loading the phloem with sugars. The bryophytes lack phloem, but moss sporophytes have a simpler tissue with analogous function known as the leptome.

Question: What is the leptome?
Answer: simpler tissue with analogous function
Plant cells differentiate from undifferentiated meristematic cells (analogous to the stem cells of animals) to form the major classes of cells and tissues of roots, stems, leaves, flowers, and reproductive structures, each of which may be composed of several cell types.

Question: what are the resultant of plant cell differentiation?
Answer: orm the major classes of cells and tissues of roots, stems, leaves, flowers, and reproductive structures
The plant epidermis is specialised tissue, composed of parenchyma cells, that covers the external surfaces of leaves, stems and roots. Several cell types may be present in the epidermis. Notable among these are the stomatal guard cells that control the rate of gas exchange between the plant and the atmosphere, glandular and clothing hairs or trichomes, and the root hairs of primary roots.  In the shoot epidermis of most plants, only the guard cells have chloroplasts. Chloroplasts contain the green pigment chlorophyll  which is needed for photosynthesis.  The epidermal cells of aerial organs arise from the superficial layer of cells known as the tunica (L1 and L2 layers) that covers the plant shoot apex, whereas the cortex and vascular tissues arise from innermost layer of the shoot apex known as the corpus (L3 layer). The epidermis of roots originates from the layer of cells immediately beneath the root cap. The epidermis of all aerial organs, but not roots, is covered with a cuticle made of polyester cutin or polymer cutan (or both), with a superficial layer of epicuticular waxes. The epidermal cells of the primary shoot are thought to be the only plant cells with the biochemical capacity to synthesize cutin.

Question: Epidermal cells can do what?
Answer: synthesize cutin
Xylem is a complex vascular tissue composed of water-conducting tracheids or vessel elements, together with fibres and parenchyma cells. Tracheids  are elongated cells with lignified secondary thickening of the cell walls, specialised for conduction of water, and first appeared in plants during their transition to land in the Silurian period more than 425 million years ago (see Cooksonia). The possession of xylem tracheids defines the vascular plants or Tracheophytes. Tracheids are pointed, elongated xylem cells, the simplest of which have continuous primary cell walls and lignified secondary wall thickenings in the form of rings, hoops, or reticulate networks. More complex tracheids with valve-like perforations called bordered pits characterise the gymnosperms. The ferns and other pteridophytes and the gymnosperms have only xylem tracheids, while the flowering plants also have xylem vessels. Vessel elements are hollow xylem cells without end walls that are aligned end-to-end so as to form long continuous tubes. The bryophytes lack true xylem tissue, but their sporophytes have a water-conducting tissue known as the hydrome that is composed of elongated cells of simpler construction.

Question: What kind of plants possess xylem?
Answer: Tracheophytes

Question: Fibers, parenchyma cella and which other vessels compose Xylem?
Answer: Tracheids
Booth was born in Gloucester, England in 1871. He was educated at Gloucester College and Gloucester County School under headmaster the Reverend H. Lloyd Brereton. In 1889 he entered the Central Technical College, City and Guild, London after passing the entrance examination. He completed a three-year course in civil engineering and  mechanical engineering under Professor William Cawthorne Unwin FRS. He completed the Diploma of Associateship (ACGI), coming second in the engineering department. He became a student of the Institution of Civil Engineers.

Question: In what area was his Diploma?
Answer: engineering
Edgar Allan Poe (; born Edgar Poe; January 19, 1809 – October 7, 1849) was an American writer, editor, and literary critic. Poe is best known for his poetry and short stories, particularly his tales of mystery and the macabre. He is widely regarded as a central figure of Romanticism in the United States and of American literature as a whole, and he was one of the country's earliest practitioners of the short story. He is generally considered the inventor of the detective fiction genre and is further credited with contributing to the emerging genre of science fiction. He was the first well-known American writer to earn a living through writing alone, resulting in a financially difficult life and career.Poe was born in Boston, the second child of actors David and Elizabeth "Eliza" Arnold Hopkins Poe. His father abandoned the family in 1810, and his mother died the following year. Thus orphaned, the child was taken in by John and Frances Allan of Richmond, Virginia. They never formally adopted him, but he was with them well into young adulthood. Tension developed later as John Allan and Poe repeatedly clashed over debts, including those incurred by gambling, and the cost of Poe's secondary education. He attended the University of Virginia but left after a year due to lack of money. Poe quarreled with Allan over the funds for his education and enlisted in the Army in 1827 under an assumed name. It was at this time that his publishing career began with the anonymous collection Tamerlane and Other Poems (1827), credited only to "a Bostonian". Poe and Allan reached a temporary rapprochement after the death of Frances Allan in 1829. Poe later failed as an officer cadet at West Point, declaring a firm wish to be a poet and writer, and he ultimately parted ways with John Allan.

Question: What school did Poe attend?
Answer: University of Virginia
Poe planned for years to produce his own journal The Penn (later renamed The Stylus), but he died before it could be produced. He died in Baltimore on October 7, 1849, at age 40; the cause of his death is unknown and has been variously attributed to alcohol, "brain congestion", cholera, drugs, heart disease, rabies, suicide, tuberculosis, and other causes.Poe and his works influenced literature around the world, as well as specialized fields such as cosmology and cryptography. He and his work appear throughout popular culture in literature, music, films, and television. A number of his homes are dedicated museums today. The Mystery Writers of America present an annual award known as the Edgar Award for distinguished work in the mystery genre.

Question: What was the originally planned name for this work?
Answer: The Penn
Poe switched his focus to prose and spent the next several years working for literary journals and periodicals, becoming known for his own style of literary criticism. His work forced him to move among several cities, including Baltimore, Philadelphia, and New York City. He married Virginia Clemm in 1836, his 13-year-old cousin. In January 1845, Poe published his poem "The Raven" to instant success, but Virginia died of tuberculosis two years after its publication.

Question: Who did Poe marry eventually?
Answer: Virginia Clemm
A basic metabolic panel measures sodium, potassium, chloride, bicarbonate, blood urea nitrogen (BUN), magnesium, creatinine, glucose, and sometimes calcium.  Tests that focus on cholesterol levels can determine LDL and HDL cholesterol levels, as well as triglyceride levels.Some tests, such as those that measure glucose or a lipid profile, require fasting (or no food consumption) eight to twelve hours prior to the drawing of the blood sample.For the majority of tests, blood is usually obtained from the patient's vein. Other specialized tests, such as the arterial blood gas test, require blood extracted from an artery. Blood gas analysis of arterial blood is primarily used to monitor carbon dioxide and oxygen levels related to pulmonary function, but is also used to measure blood pH and bicarbonate levels for certain metabolic conditions.While the regular glucose test is taken at a certain point in time, the glucose tolerance test involves repeated testing to determine the rate at which glucose is processed by the body.

Question: What are the other specialized treatments?
Answer: arterial blood gas test
A venipuncture is useful as it is a minimally invasive way to obtain cells and extracellular fluid (plasma) from the body for analysis. Blood flows throughout the body, acting as a medium which provides oxygen and nutrients to tissues and carries waste products back to the excretory systems for disposal. Consequently, the state of the bloodstream affects, or is affected by, many medical conditions. For these reasons, blood tests are the most commonly performed medical tests.If only a few drops of blood are needed, a fingerstick is performed instead of a venipuncture.Phlebotomists, laboratory practitioners and nurses are those in charge of extracting blood from a patient. However, in special circumstances, and emergency situations, paramedics and physicians extract the blood. Also, respiratory therapists are trained to extract arterial blood to examine arterial blood gases.

Question: When might someone other than a phlebotomist draw blood from a patient?
Answer: special circumstances, and emergency situations
Polymerase chain reaction (DNA). DNA profiling is today possible with even very small quantities of blood: this is commonly used in forensic science, but is now also part of the diagnostic process of many disorders.

Question: where is DNA used today?
Answer: forensic science
NTSC color encoding is used with the System M television signal, which consists of ​30⁄1.001 (approximately 29.97) interlaced frames of video per second. Each frame is composed of two fields, each consisting of 262.5 scan lines, for a total of 525 scan lines. 486 scan lines make up the visible raster. The remainder (the vertical blanking interval) allow for vertical synchronization and retrace. This blanking interval was originally designed to simply blank the receiver's CRT to allow for the simple analog circuits and slow vertical retrace of early TV receivers. However, some of these lines may now contain other data such as closed captioning and vertical interval timecode (VITC). In the complete raster (disregarding half lines due to interlacing) the even-numbered scan lines (every other line that would be even if counted in the video signal, e.g. {2, 4, 6, ..., 524}) are drawn in the first field, and the odd-numbered (every other line that would be odd if counted in the video signal, e.g. {1, 3, 5, ..., 525}) are drawn in the second field, to yield a flicker-free image at the field refresh frequency of ​60⁄1.001 Hz (approximately 59.94 Hz). For comparison, 576i systems such as PAL-B/G and SECAM use 625 lines (576 visible), and so have a higher vertical resolution, but a lower temporal resolution of 25 frames or 50 fields per second.

Question: What did CRT TV's need a vertical blanking interval for?
Answer: vertical synchronization and retrace

Question: What type of circuits were used in early TV receivers?
Answer: analog
The 59.94 rate is derived from the following calculations. Designers chose to make the chrominance subcarrier frequency an n + 0.5 multiple of the line frequency to minimize interference between the luminance signal and the chrominance signal. (Another way this is often stated is that the color subcarrier frequency is an odd multiple of half the line frequency.) They then chose to make the audio subcarrier frequency an integer multiple of the line frequency to minimize visible (intermodulation) interference between the audio signal and the chrominance signal. The original black-and-white standard, with its 15,750 Hz line frequency and 4.5 MHz audio subcarrier, does not meet these requirements, so designers had either to raise the audio subcarrier frequency or lower the line frequency. Raising the audio subcarrier frequency would prevent existing (black and white) receivers from properly tuning in the audio signal. Lowering the line frequency is comparatively innocuous, because the horizontal and vertical synchronization information in the NTSC signal allows a receiver to tolerate a substantial amount of variation in the line frequency. So the engineers chose the line frequency to be changed for the color standard. In the black-and-white standard, the ratio of audio subcarrier frequency to line frequency is ​4.5 MHz⁄15,750 Hz = 285.71. In the color standard, this becomes rounded to the integer 286, which means the color standard's line rate is ​4.5 MHz⁄286 ≈ 15,734 Hz. Maintaining the same number of scan lines per field (and frame), the lower line rate must yield a lower field rate. Dividing ​4500000⁄286 lines per second by 262.5 lines per field gives approximately 59.94 fields per second.

Question: How much does the division yield approximate in fields per second?
Answer: 59.94
The National Television System Committee was established in 1940 by the United States Federal Communications Commission (FCC) to resolve the conflicts between companies over the introduction of a nationwide analog television system in the United States. In March 1941, the committee issued a technical standard for black-and-white television that built upon a 1936 recommendation made by the Radio Manufacturers Association (RMA). Technical advancements of the vestigial side band technique allowed for the opportunity to increase the image resolution. The NTSC selected 525 scan lines as a compromise between RCA's 441-scan line standard (already being used by RCA's NBC TV network) and Philco's and DuMont's desire to increase the number of scan lines to between 605 and 800. The standard recommended a frame rate of 30 frames (images) per second, consisting of two interlaced fields per frame at 262.5 lines per field and 60 fields per second. Other standards in the final recommendation were an aspect ratio of 4:3, and frequency modulation (FM) for the sound signal (which was quite new at the time).

Question: What standard was recommended for the sound signal?
Answer: frequency modulation (FM)

Question: How many scan lines did NTSC select as a compromise?
Answer: 525
The actual figure of 525 lines was chosen as a consequence of the limitations of the vacuum-tube-based technologies of the day. In early TV systems, a master voltage-controlled oscillator was run at twice the horizontal line frequency, and this frequency was divided down by the number of lines used (in this case 525) to give the field frequency (60 Hz in this case). This frequency was then compared with the 60 Hz power-line frequency and any discrepancy corrected by adjusting the frequency of the master oscillator. For interlaced scanning, an odd number of lines per frame was required in order to make the vertical retrace distance identical for the odd and even fields, which meant the master oscillator frequency had to be divided down by an odd number.

Question: How many lines was it?
Answer: 525
Diabetic neuropathy affects all peripheral nerves including sensory neurons, motor neurons, but rarely affects the autonomic nervous system.  Therefore, diabetic neuropathy can affect all organs and systems, as all are innervated. There are several distinct syndromes based on the organ systems and members affected, but these are by no means exclusive. A patient can have sensorimotor and autonomic neuropathy or any other combination. Signs and symptoms vary depending on the nerve(s) affected and may include symptoms other than those listed. Symptoms usually develop gradually over years.

Question: when do the symptoms develop?
Answer: gradually over years

Question: What factor causes varied and possibly additional symptoms?
Answer: the nerve(s) affected
Globally diabetic neuropathy affects approximately 132 million people as of 2010 (1.9% of the population).Diabetes is the leading known cause of neuropathy in developed countries, and neuropathy is the most common complication and greatest source of morbidity and mortality in diabetes. It is estimated that neuropathy affects 25% of people with diabetes. Diabetic neuropathy is implicated in 50–75% of nontraumatic amputations.

Question: what %does neurotherapy affect people with diabetes
Answer: 25%
Longer nerve fibers are affected to a greater degree than shorter ones because nerve conduction velocity is slowed in proportion to a nerve's length. In this syndrome, decreased sensation and loss of reflexes occurs first in the toes on each foot, then extends upward. It is usually described as a glove-stocking distribution of numbness, sensory loss, dysesthesia and night time pain. The pain can feel like burning, pricking sensation, achy or dull. A pins and needles sensation is common. Loss of proprioception, the sense of where a limb is in space, is affected early. These patients cannot feel when they are stepping on a foreign body, like a splinter, or when they are developing a callous from an ill-fitting shoe. Consequently, they are at risk of developing ulcers and infections on the feet and legs, which can lead to amputation. Similarly, these patients can get multiple fractures of the knee, ankle or foot, and develop a Charcot joint. Loss of motor function results in dorsiflexion, contractures of the toes, loss of the interosseous muscle function that leads to contraction of the digits, so-called hammer toes. These contractures occur not only in the foot but also in the hand where the loss of the musculature makes the hand appear gaunt and skeletal. The loss of muscular function is progressive.

Question: The speed of a nerve's conduction velocity is affected by what?
Answer: nerve's length

Question: Which part of the body does one experience less feeling in first with the syndrome?
Answer: toes
The autonomic nervous system is composed of nerves serving the heart, lungs, blood vessels, bone, adipose tissue, sweat glands, gastrointestinal system and genitourinary system. Autonomic neuropathy can affect any of these organ systems. The most commonly recognized autonomic dysfunction in diabetics is orthostatic hypotension, or becoming dizzy and possibly fainting when standing up due to a sudden drop in blood pressure. In the case of diabetic autonomic neuropathy, it is due to the failure of the heart and arteries to appropriately adjust heart rate and vascular tone to keep blood continually and fully flowing to the brain.  This symptom is usually accompanied by a loss of respiratory sinus arrhythmia – the usual change in heart rate seen with normal breathing. These two findings suggest autonomic neuropathy.

Question: What can affect other organs?
Answer: Autonomic neuropathy
The main risk factor for diabetic neuropathy is hyperglycemia.  In the DCCT (Diabetes Control and Complications Trial, 1995) study, the annual incidence of neuropathy was 2% per year but dropped to 0.56% with intensive treatment of Type 1 diabetics. The progression of neuropathy is dependent on the degree of glycemic control in both Type 1 and Type 2 diabetes. Duration of diabetes, age, cigarette smoking, hypertension, height, and hyperlipidemia are also risk factors for diabetic neuropathy.

Question: What can lead to diabetic neuropathy?
Answer: hyperglycemia
