Published: October 2018

Background: Gynecological problems of adolescents occupy a special space in the spectrum of gynecological disorders of all ages. In this study, an attempt has been made to review the health profile of adolescent girls visiting department of Obstetrics and Gynecology of a tertiary care hospital.Methods: This observational study was conducted at a tertiary care teaching hospital during June 2014 to May 2016. Data was collected after due permission.Results: Adolescent girls having gynecological problems were 2.3%. Mean age of menarche was 12.5 years. Anemia was present in 89(62.7%). About 72(50.7%) adolescent girls were having abnormal body mass index (BMI). Majority of girls 136(95.8%) had menstrual problems. Leucorrhoea, Pelvic Inflammatory Disease (PID), ovarian mass, urinary problems, breast problems, injury to genital tract and sexual assault were present in 42(29.6%), 24(16.9%), 20(14.1%), 13(9.2%), 12(8.5%), 4(2.8%) and 1(0.7%) respectively.Conclusions: A very small proportion of adolescent girls came to the hospital for health-related issues. Anemia was present in more than half of adolescent girls and almost half of adolescent girls were having abnormal BMI. Majority of adolescent girls had menstrual problems. Health education regarding normal physiology, various gynecological problems, importance of nutrition and exercise for adolescents is necessary.

Authors: Nayak Prasanta K. , Mukherjee Chandrima , Mitra Subarna
Published: October 2018

Background: The objective of the present study was to establish the role of AFC as a marker of ovarian reserve in fertility-proven and in sub-fertile Indian women, and to establish the baseline cut-off AFC values for Indian women.Methods: This is an Observational Case-Control type of study. Test subjects (n=30, age range 20-35 years) were selected randomly from all the women coming to our Out-Patient Department with Primary Infertility. Healthy female volunteers (n=30, age range 20-35years) were recruited from the local population. Statistics: Student t test was applied to compare the mean Antral Follicle count between the case and control group. Pearson correlation test was applied to assess the correlation between age and AFC for case and control group.Results: The results of the study show that there is a significant difference between the number of antral follicles between fertile and infertile women (p < 0.001). The baseline cut-off for successful pregnancy was established as an AFC of 12. There exists negative correlation (r = -0.249) between age and AFC case group indicating as the age increases AFC decreases.Conclusions: The findings from this study help in strengthening the idea that AFC serves as a marker for ovarian reserve. Our observation indicates that the number of antral follicles is lower in the subfertile patients as compared to the fertile group (in all age groups), in view of the significantly lower median AFC in women of the former group (P < 0.001).

Background: Postpartum hemorrhage is one of the leading causes of maternal death in the entire world. It affects 10% of deliveries. Emergency peripartum hysterectomy (EPH)defined as a lifesaving procedure involving the removal of the uterus to treat severe postpartum hemorrhage is one of the last-resort treatments for severe postpartum hemorrhage in case of failure of other techniques. Through this study, we aimed both to describe the epidemiological profile, to determine the etiologies, and maternal complications of EPH.Methods: It is about a descriptive retrospective study from January 1st, 2016 to January 1st, 2017 at the Befelatanana University Hospital of Obstetrics and Gynecology. We included all patients who underwent Emergency peripartum hysterectomy after 22 weeks of Amenorrhea (WA) regardless of the delivery route in the centre. We used the R software for the statistical analysis of the results.Results: We had 31 cases of EPH during this period with a prevalence of 0.44%. The average age was 26.38±5.61 years. Mean gestational age was 37±3.59 weeks of amenorrhea. In the 83.87% of cases, the patient received less than four prenatal consultations. Patients were referred in 45.16% of the cases. The delivery route was by cesarean section in 48.39% of cases. Eleven patients (35.48%) received a blood transfusion. Hysterectomy was subtotal in 96.77% of the cases. We had five (16.13%) maternal deaths during the study period. The leading cause of death was hemorrhagic shock (80%). The etiology of hysterectomy was dominated by uterine atony complicated by hemorrhage (48.39%), followed by retroplacental hematoma (25.81%) and uterine rupture (22.58%).Conclusions: EPH still holds its place in the management of postpartum hemorrhage in Madagascar. Maternal mortality remains high. Uterine atony was the most common indication for EPH. The prevention of postpartum hemorrhage by management of the third stage of labour should be carried out by any health actor.

Published: October 2018

Ectopic pregnancy is a condition in which the fertilized ovum is impacted anywhere other than the uterine cavity, these sites may be uterine tubes, cervix, ovary and abdomen. Ectopic implantation in the uterine tubes occurs up to 98%. The distribution according to its location is: 78% ampullary, 12% isthmic, 5% fibrous, 2-3% interstitial, 1% ovarian, 1-2% abdominal, and more rare in cervix with 0.5%. Ectopic pregnancy occurs 1.2 to 2% of pregnancies, with an associated mortality of 0.5 deaths per 1000 pregnancies. There are multiple risk factors for an ectopic pregnancy, among the most frequent are: women with pelvic inflammatory disease (salpingitis) conditioned mainly by Chlamydia trachomatis and Neisseria gonorrhea, anatomical abnormalities of the tubes, previous surgery in them (including sterilization), masses extrinsic tumors that compress them, endometriosis, zygote anomalies, endocrinopathies (corpus luteum deficiency in late ovulation), use of intrauterine devices, previous ectopic pregnancy (as a result of surgical treatment or due to persistence of the original risk factor), contraceptive users with gestagens in low doses, assisted reproduction techniques, smokers, secondary adhesions to surgical interventions on the uterus, ovaries, and other pelvic or abdominal organs, exposure of the uterus to diethylstilbestrol, among others. The objective of this case is to describe an advanced tubal ectopic pregnancy. The following case report is about a 24-year-old patient with a pregnancy of 19 weeks of gestation by first-trimester ultrasound and a history of recent laparoscopic cholecystectomy secondary to biliary lithiasis. He is in the first trimester of normo-evolutive and without symptoms. Authors present to the emergency department with a 24-hour abdominal pain syndrome that requires exploratory laparotomy and right salpingo-oophorectomy due to the presence of ruptured tubal ectopic pregnancy with average fetometry of 19 weeks of gestation. The patient is discharged after an adequate clinical evolution.

Published: October 2018

Background: The diagnosis and prognosis of breast cancer is done with various immunomarkers including estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor-2 (HER2/neu), and Ki-67. The diagnostic utility of Anaplastic Lymphokinase (ALK) and HER2/neu should be explored for better management of breast carcinoma patients. So, the present study was designed to determine the expression of immunostaining with ALK and HER2/neu in patients with breast cancer and to compare the association of ALK expression and HER2/neu with clinicopathological parameters.Methods: This is a cross sectional multicenter study carried out from October 2016 to March 2017. A total of 140 subjects having breast carcinoma by using non-probability purposive sampling technique were selected. After taking informed consent, tissue samples were taken from received specimen of mastectomy for hematoxylin and eosin stain. The immunohistochemistry for ALK and HER2/neu were assessed on the paraffin blocks of the tumor.Results: Out of total 140 cases invasive ductal carcinoma (89%), invasive lobular carcinoma (8%), invasive medullary carcinoma (2.1%) and papillary carcinoma (0.7%) were seen. ALK expression was positive in 81 patients (58%) while HER2/neu expression was positive in 53 cases (38%). Significant association was observed between ALK expression with histological grade, lymph node involvement, skin involvement and necrosis. There was also a significant association was seen between HER2/neu expression with lymph node metastasis and necrosis.Conclusions: Present study shows higher expression of ALK when compared to HER2/neu expression in breast cancer patients.

Authors: Ghrayeb Farid Abdulwahab , Rimawz Omar , Nimer Azzam
Published: October 2018

Background: Cancer is a major public health problem globally. The incidence of cancer is escalating rapidly in many low- and middle-income countries like Palestine due to the epidemiological transition. This could be due to lack of awareness, knowledge and beliefs about breast cancer and its management among females. Aims and objectives was to determine knowledge of breast cancer risk factors, symptoms and early detection methods among Al-Quds University female students.Methods: A descriptive cross-sectional study conducted over a period of 6 months in Al-Quds University. Study population was 332 female university students. Data was collected by using self-administered questionnaire.Results: The most widely known risk factors by the students were old age 62.7%, followed by obesity 44% and never being pregnant 30.7%. Approximately half of the students (48.8%) identified breast lump as a symptom for breast cancer. However, non lump symptoms were less known and less than half were aware of other warning signs. Only 48.5 % of students identified correctly the appropriate time to perform breast self examination.Conclusions: The findings of this study showed a low level of knowledge on breast cancer risk factors, early warning signs and BSE among female university students. Therefore, effective educational programs are required to improve the knowledge level of university students regarding breast cancer and related practices.

Published: October 2018

Background: Problem-based learning is an instructional approach that emphasizes inquiry. Problem-based learning was developed in the late 1960s and has been the most influential innovation in medical education during the past 50 years. Implementation of problem-based learning requires fundamental changes in the way educators conceive, design, deliver, and assess the curriculum. We designed this cross-sectional study to determine whether the staff members in the clinical years in the faculty of medicine in Northern Border University (NBU) has a previous experience with problem-based learning methods of teaching and to know their attitude towards it.Methods: Data were collected from 46 staff members in the clinical years of the faculty of medicine using hard copy questionnaire and analyzed using statistical package for social sciences software program.Results: The results showed that eighty percent of the clinical staff were graduated from colleges using the classical curriculum. Around 30% of them worked as PBL tutors before joining the faculty of medicine but all of them worked as PBL tutors after joining. Only one-third of the clinical staff know the steps of PBL when joining the faculty of medicine. Around 80% of study group think that hybrid curriculum is the best curriculum for faculties of medicine.Conclusions: The study group had the knowledge, practice, and experience of PBL method of teaching, they attended PBL workshops and like to attend more PBL workshops, in addition, the majority of faculty members think that the hybrid curriculum is the best for implementation in faculties of medicine.

Published: October 2018

Background: Chronic suppurative otitis media (CSOM) is a massive public health problem in developing countries like India, especially among low socio-economic class because of malnutrition, overcrowding, poor hygiene, inadequate health care and recurrent upper respiratory tract infections. CSOM cases unless managed effectively may land into various complications such as persistent otorrhoea, hearing impairment, mastoiditis, labyrinthitis, facial nerve paralysis to more serious intracranial abscesses.Methods: The study was carried out in a tertiary care hospital from January 2017 to December 2017 with an aim to determine the microbiological profile of ear discharge in patients suffering from CSOM and their antimicrobial susceptibility pattern using Kirby Bauer disc diffusion method.Results: Out of 630 samples processed, 407 (64.6%) samples were culture positive. Most common organism isolated was Pseudomonas spp. (43.2%) followed by S. aureus (39.1%). Most of isolates recovered were multidrug resistant.Conclusions: Management of CSOM consists mainly of eradicating infection and closure of tympanic membrane. Periodic monitoring of bacterial isolates and their antibiotic susceptibility pattern is necessary for administering appropriate antibiotics as empirical treatment and also helps in reducing the potentially disabling and fatal complications of CSOM.

Published: October 2018

Background: Puberty is the unique stage of growth and development associated with the social and psychological changes referred to as adolescence. The adolescent psychosocial development is the process through which the dependent child becomes a self reliant adult. A large number of adolescents suffer from psychosocial problems and many of these problems are of transient in nature and are often not even noticed. The objective of the study was to find out the prevalence of psychosocial problems among adolescents.Methods: A cross-sectional study was conducted in ward no 58 of Tangra area of Kolkata. The study group comprised of 420 adolescents, selected by multistage stratified random sampling. Data was collected on a pre-designed and pre-tested questionnaire by interviewing the adolescents and was subsequently analyzed by using suitable statistical package.Results: Anxiety was maximum (34.76%) in adolescent boys whereas conduct disorder was found to be maximum (28.57%) in adolescent girls. Majority (35.62%) of late adolescent boys were attributed to substance abuse. Anxiety was found to be the commonest problem among adolescent males in all religions. Educational difficulties were maximum among Muslim adolescents. The problems per subject (with psycho-social problems) were more in adolescent boys (4.4) and girls (3.8) having joint family. None of the class I adolescent girls claimed to have any educational difficulties.Conclusions: A holistic approach to underlying causes of psycho-social problems of adolescents should be undertaken. There is need of strengthening the existing “package” of services for adolescents in various initiatives and programmes.

It is commonly found in long term urinary catheter used and immune system deficiency patients as nosocomial disease. Morganella morganii was also involving skin, skeletal system and central nervous system. In this case we present sporadic Morganella morganii infection on sinonasal region with the presence of sinusitis, orbital absess, preseptal cellulitis and lamina propasia defect on 58 year old female diabetic patient. Microbiological assessment from nasal tissue and sinus puss discharge were reported as Morganella morganii. This is the first case of sinonasal Morganella morganii infection with sinonasal, preseptal cellulitis and orbital absess with lamina papyracea bone destruction.
Management of carbamazepine induced drug reaction with eosinophlia and systemic symptoms in Mediheal hospital-Nakuru, Kenya: a case report
Authors: Mawenzi Ramadhan L. , Parikh Dhiren
Published: October 2018

Adverse drug reactions (ADR) are undesirable events occurring as consequences of an ingested, injected or applied drug. Their spectrum can range from mild to severe reactions. Severe Cutaneous Adverse Reactions (SCARs) are diverse in presentation and in consequence. Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) is a type of life-threatening SCAR which affects the skin as well as the internal organs. Various drugs can cause DRESS, but aromatic anticonvulsants, especially carbamazepine are considered the major culprits. The diagnosis of DRESS requires a high index of suspicion followed by an intense sign-searching clinical examination guided by established criteria. We report a previously healthy 53 year old man of Kenyan ancestry who developed fever, widespread maculopapular rash, swollen eyelids and cervical lymphadenopathy three weeks after carbamazepine. Liver enzymes were markedly elevated and he had lymphocytopenia and a positive serology for human herpes virus type 6 (HHV6). Using the RegiSCAR criteria a probable diagnosis of DRESS secondary to carbamazepine was made. His treatment involved discontinuation of the drug, intravenous hydrocortisone together with mild topical steroids. He remarkably improved and was discharged on oral prednisone and followed up for three consecutive months. The length of his hospitalisation was ten days. Carbamazepine has potential to provoke DRESS in patients of Kenyan ancestry. DRESS should be anticipated before and during use of carbamazepine for early recognition. Treatment of DRESS should involve the immediate withdrawal of offending drug and rapid initiation of systemic corticosteroids as well as application of diluted topical steroids to sooth the skin.

Wstęp

Tętniakami nazywamy każde poszerzenie światła naczynia tętniczego przekraczające 50% średnicy w stosunku do średnicy uważanej za normę dla danego odcinka aorty. Wykrywane są często przypadkowo podczas wykonywania innych badań. Tętniaki aorty piersiowej dzielą się na prawdziwe i rozwarstwiające.

Materiał i metody

Badaniem objęto wszystkich chorych z rozpoznanym tętniakiem aorty piersiowej, hospitalizowanych w Klinice Kardiologii w latach 2010–2014. Badana grupa obejmowała 50 chorych w wieku 33–92 lat (średnia wieku 64 lata), w tym 9 kobiet i 41 mężczyzn. Analizie poddano dane z historii choroby dotyczące występowania czynników ryzyka rozwoju tętniaków aorty, wywiadu chorobowego oraz wyniki przeprowadzonych badań, w tym obrazowych, oraz sposób leczenia i rokowanie.

Wyniki

Z badanej grupy 25 osób (50%) było leczonych zachowawczo, a 25 (50%) operacyjnie. Z czynników predysponujących najczęściej występowały u badanych: nadciśnienie tętnicze (n = 42; 84%), dyslipidemia (n = 25; 50%), ChNS (n = 20; 40%), palenie tytoniu (n = 14; 28%) oraz obciążający wywiad rodzinny (n = 14; 28%). W grupie chorych z tętniakami rozwarstwiającymi leczenie operacyjne było częściej wybieranym sposobem leczenia (n = 23; 60,5%). Natomiast leczenie zachowawcze było preferowane u chorych z tętniakiem prawdziwym (n = 10; 83,3%).

Wnioski

Badana grupa chorych z tętniakiem aorty piersiowej obarczona była licznymi czynnikami ryzyka ich rozwoju. Analiza sposobu leczenia badanych nie wykazała przewagi żadnej z zastosowanych metod (chirurgicznej vs. farmakologicznej), a śmiertelność podczas hospitalizacji w obu grupach była taka sama.

WPROWADZENIE

Według Międzynarodowej Klasyfikacji Chorób i Problemów Zdrowotnych ICD-10, zespół Münchhausena jest zaburzeniem psychicznym, zaliczanym do kategorii diagnostycznej F68.1 „Zamierzone wytwarzanie lub naśladowanie objawów czy niewydolności fizycznych lub psychicznych (zaburzenia pozorowane)”. W przeciwieństwie do osób świadomie symulujących dolegliwości w celu uzyskania konkretnych korzyści, chorzy z podejrzeniem zespołu Münchhausena zgłaszając się kolejny raz do placówek służby zdrowia nie są świadomi swoich wewnętrznych motywów (społeczna gratyfikacja, potrzeba kontroli, wysoki poziom autoagresji), narażając się na długi proces diagnostyczny.

CEL PRACY:

Przedstawienie trudności związanych z różnicowaniem, rozpoznawaniem i odpowiednim leczeniem zespołu Münchhausena.
Przedstawiony opis przypadku dotyczy młodej pacjentki, wielokrotnie hospitalizowanej z powodu licznych dolegliwości somatycznych, u której mimo wielu przeprowadzonych badań, w tym obrazowych i zabiegowych, nie można było postawić żadnego, tłumaczącego występujące objawy, rozpoznania. Dopiero hospitalizacja psychiatryczna, z pełną analizą dotychczasowej historii chorobowej pacjentki, pozwoliła na postawienie diagnozy zespołu Münchhausena i podjęcie właściwego leczenia. Paradoksalnie rozpoznanie to mogło przyczynić się do umniejszania zgłaszanych przez pacjentkę w późniejszym okresie dolegliwości, które pojawiły się w związku z rozrastającym się guzem mózgu.

KOMENTARZ:

Właściwe rozumienie prezentowanych przez chorą objawów mogło doprowadzić do znacznie szybszego postawienia diagnozy. Późniejsze, tragiczne w skutkach objawy pokazują, iż nie można zamykać się w obrębie jednego rozpoznania. Istotną rolę zdają się odgrywać właściwie zaplanowane badania obrazowe.

Effect of pawpaw (Carica papaya) leaf meal and dietary enzymes on broiler performance, digestibility, carcass and blood composition
Authors: Oloruntola Olugbenga David , Ayodele Simeon Olugbenga , Oloruntola Deborah Adebukola
Published: October 2018

Exogenous enzymes and phytogenic feed additives are proposed as alternatives to antibiotic growth promoters in poultry production. This study assessed the effect of pawpaw leaf meal (PLM) inclusion and enzyme (E) supplementation in the diet of broiler chickens. In total 288 Arbor-Acre day-old broiler chickens were used. Four diets were formulated to be isocaloric and isonitrogenous: diet 1, control (0% PLM, 0% E), diet 2 (0% PLM, 0.05% E), diet 3 (5% PLM, 0% E), and diet 4 (5% PLM, 0.05% E). Each diet was replicated six times with 12 chickens in each batch. E improved (p < 0.05) the body weight gain at three weeks. The dry matter (DM), crude protein (CP), ether extract and ash digestibility were improved (p < 0.05) with E, whereas PLM inclusion produced (p < 0.05) an increase in DM and CP digestibility. The E x PLM effect was significant (p < 0.05) for DM and CP digestibility. E improved (p < 0.05) the slaughter weight and reduced the liver weight. Platelets varied across diets and increased (p < 0.05) with enzyme supplementation. E reduced (p < 0.05) low-density lipoproteins (LDL), whereas PLM reduced (p < 0.05) cholesterol and LDL. In conclusion, the association of E and PLM improved chicken growth, and E or PLM inclusion should benefit chicken health.

Sobre o uso dos termos geocronológicos e cronoestratigráficos
Authors: Arai Mitsuru , Branco Pércio de Moraes
Published: October 2018

Este artigo pretende estabelecer padrões, visando o uso correto de termos cronoestratigráficos e geocronológicos na literatura geocientífica. A distinção entre os dois tipos de termos foi claramente apontada pelo Guia de Nomenclatura Estratigráfica Brasileira de 1986. No entanto, o que vem se observando frequentemente é o uso equivocado desses termos, ou seja, o uso de termos cronoestratigráficos no lugar dos geocronológicos, e vice-versa. No início da década de 1990, o primeiro autor começou uma campanha contra esse mau uso por meio de contatos pessoais e da publicação de pequenas notas sobre a problemática. A decisão de escrever um artigo mais extenso e abrangente decorreu do fato do primeiro autor ter passado a fazer parte dos comitês editoriais dos periódicos Boletim de Geociências da Petrobras (2006–2013) e Revista Brasileira de Paleontologia (desde 2016), o que lhe permitiu ter a noção da gravidade da questão.
Dichotomous options in earth sciences education: brief reflection
Authors: Soares Paulo Cesar
Published: October 2018

The explosion and dissemination of knowledge and technologies is one of the characteristics of the current time. The teacher is no longer the reference of knowledge or competence. The expansion and deepening of concepts and methods grow exponentially. Knowledge does not provide a clear path to future life success. Earth-related issues are global sustainability concerns. Now, the claim is to pick up and deal with the information to solve specific problems. The expert apps have become powerful tools for learning and professional operations. There is a new student with different problems, social environment and motivations, especially his appreciation for autonomy, in an immense diversity of offers and demands. And there is new ways to learn, more friendly but more away from the real world. What does this change in the curricula and for the teacher and student in the classroom? Two opposite answers are the common behavior: focus on teaching or focus on learning. In the first, good teachers will look for the best subjects, based on gaps and remarkable discoveries and good examples in the body of scientific knowledge and attractive ways of presenting them to students. In the second, good teachers will help and guide students to organize and work to find the most appropriate and motivating issues and ways to deal with them to be useful in their lives. Earth sciences have many problems, solutions and challenges, daily in the news and in the surroundings of place and student life. Students become proud to be active in the group, in his real world, according to his needs, his challenges; and they need help and guidan­ce in this process. Teachers will focus on the motivations of these students to build their knowledge, their being, their skills, their professional abilities, their commitments as citizens and the reasons to lifelong learning.

Brazil faces educational and environmental crisis that enhance the importance of valuing geoscientific contents in school cur-ricula, especially in basic education. The modality of technical education integrated to high school courses (TEIHSC) open broad possibilities to build an integrated view of nature and of human interference. However, the current situation is one of great fragmentation of contents and diversification of teaching-learning approaches. As a contribution to understand better the national reality, the present project aims to carry out a survey of geoscientific themes present in the Brazilian official curricula of TEIHS courses and in the curricula of secondary professional education of public schools in Portugal. The distribution of technical schools in this teaching modality – TEIHS comprises the states of São Paulo, Rio de Janeiro, Minas Gerais and Espíri-to Santo and even in the official curricula of federal technical schools situated in these states. This project should discuss cur-ricular convergences and divergences from the background of the following courses: Agriculture, Surveying, Environmental Control, Forestry, Environment, Mining, Oil and Gas, Environmental Management, Agricultural Production, Forestry and Envi-ronmental Resources, Tourism and Environmental and Rural Tourism. The investigation will produce a comprehensive pano-rama of proposals for including geoscientific contents within this type of school integrative curriculum. The debate should at-tempt to recompose the basic needs to help citizens for taking well-founded decisions about socioeconomic, political and envi-ronmental changes.
SpArcFiRe: Enhancing Spiral Galaxy Recognition using Arm Analysis and Random Forests

Automated machine classifications of galaxies are necessary because the size of upcoming surveys will overwhelm human volunteers. We improve upon existing machine classification methods by adding the output of SpArcFiRe to the inputs of a machine learning model. We use the human classifications from Galaxy Zoo 1 (GZ1) to train a random forest of decision trees to reproduce the human vote distributions of the Spiral class. We prefer the random forest model over other black box models like neural networks because it allows us to trace post hoc the precise reasoning behind the classification of each galaxy. We find that, across a sample of 470,000 Sloan galaxies that are large enough that details could be seen if they were there, the combination of SpArcFiRe outputs with existing SDSS features provides a better machine classification than either one alone on comparison to Galaxy Zoo 1. We suggest that adding SpArcFiRe outputs as features to any machine learning algorithm will likely improve its performance.

Oriental lacquer, a natural and renewable polymeric coating, comes from the sap produced by lacquer trees. For practical application, oriental lacquer must be refined to reduce excess water and enhance its quality. In this study, drying oils were blended with oriental lacquer during the refining process to prepare an oil-modified refined lacquer (OMRL). The type and adding amount (0, 10, and 20% by wt.) of drying oils for wood coatings utilization were evaluated. Rhus succedanea oriental lacquer is composed of 54.1% urushiols, 34.3% water, 7.2% plant gum, and 4.4% nitrogenous compounds, and drying oils, including tung oil (TO), linseed oil (LO), and dehydrated castor oil (DCO) were used as materials in this study. The results show that the drying oil acts as a diluent, which reduces the viscosity and enhances the workability and could shorten the touch-free drying time and speed up the hardened drying of the OMRL. The results also indicate that the hardness, mass retention, Tg, tensile strength, abrasion resistance, and lightfastness of OMRL films decrease as more drying oils are blended. Conversely, the bending resistance, elongation at break, impact resistance increase, and particularly, the gloss, is greatly improved through the blending of more drying oils. In conclusion, the LO-modified refined lacquer (RL) has the highest film gloss and the DCO-modified RL has the shortest drying time for coating; otherwise, the film properties are similar among the three types of drying oil.

Schistosoma infection in snails can be monitored by microscopy or indirectly by sentinel mice. As both these approaches sometimes miss infections, more sensitive tests are needed, particularly in low-level transmission settings. In this study, the loop-mediated isothermal amplification (LAMP) technique, designed to detect a specific 28S ribosomal S. japonicum gene with high sensitivity, was compared to microscopy using snail samples from 51 areas endemic for schistosomiasis in five Chinese provinces. The results were compared with those by polymerase chain reaction (PCR) adding DNA sequencing as a reference when needed. The testing of pooled snail samples showed that a dilution factor of 1/50, i.e., one infected snail plus 49 non-infected ones, would still result in a positive reaction after the recommended number of amplification cycles. Testing a total of 232 pooled samples, emanating from 4,006 snail specimens, with the LAMP assay showed a 6.5% rate of infection, while traditional microscopy found only 0.04% positive samples in the same materials. Parallel PCR analysis confirmed the diagnostic accuracy of the LAMP assay, with DNA sequencing even giving LAMP a slight lead. Microscopy and the LAMP test were carried out at local schistosomiasis-control stations demonstrating that the potential of the latter assay to serve as a point-of-care (POC) test with results available within 60–90 minutes, while the more complicated PCR test had to be carried out at the National Institute of Parasitic Diseases (NIPD) in Shanghai, China. In conclusion, LAMP was found to be clearly superior to microscopy and as good as, or better, than PCR. Application of LAMP testing would be useful for surveillance and risk prediction as it requires less time than other techniques and can be used under field conditions, which improves and accelerates schistosomiasis control.
On the Nature of Irrationality
Authors: Cambaza Edgar
Published: October 2018

It has been a challenge to visualize in nature some concepts from abstract subjects such as mathematics and philosophy. Irrationality is certainly among the least comprehensive. This essay aimed to propose that irrationality is simply an illusion resulting from the human inability to grasp the full nature of reality, rather than actual continuity flaws in the fabric of existence. There are three major arguments: (1) human senses have limitations and these are likely to be extended to the intellect, (2) there are no observable existential discontinuities in everyday experience, and (3) some rational phenomena have irrational components. These arguments point towards the existence of a physical existence of irrational quantities or distances, visible to the human eye but not fully comprehended through arithmetic abstraction.
Impact of Nitrogen and Sulfur Supply on the Potential of Acrylamide Formation in Organically and Conventionally Winter Wheat

In a two-year field trial, the effect of nitrogen (N) and sulfur (S) fertilization was investigated on grain yield, grain quality parameters, formation of acrylamide (AA), and the precursor free asparagine (Asn) in organically and conventionally produced winter wheat cultivars. In both production systems, different types, amounts, and temporal distributions of N were tested. While the effect of S fertilizer types and amounts on free Asn was only tested in the conventional farming system. Within both cropping systems, grain yield and baking quality were significantly influenced by N treatment while the effect on free Asn was only minor. Especially within the organic farming system, increasing N fertilization levels did not increase free Asn significantly. A slight trend of increasing free Asn levels with an intensified N supply was observed, especially in the presence of crude protein contents of 14% or higher. But only N amounts of 180 kg N ha−1 or higher increased the probability of high free Asn contents considerably, while N supply below that amount led to free Asn values similar to the unfertilized controls. The results indicated that good baking quality can be achieved without significantly increasing free Asn levels. In addition, cultivars affected the levels of free Asn significantly. Compared to cv. “Bussard” and “Naturastar”, cv. “Capo” exhibited the lowest AA formation potential at an N supply of 180 kg N ha−1 while simultaneously reaching a crude protein content > 15% (conventional) and > 12% (organic). Thus, it seems that cultivars differ in their ability to store and incorporate free Asn into proteins. Over all trials, a correlation of free Asn and AA was shown by R2 = 0.77, while a relation of free Asn and protein was only R2 = 0.36. Thus, lowering free Asn by adjusting N treatments should not necessarily affect baking quality. S nutrition within conventional farming did not change free Asn amount or crude protein significantly, probably due to the fact that soil was not sulfate-deficient. In summary, it was evident that free Asn amounts in wheat varied widely both within cultivars and between cropping systems. In order to clearly unravel genotypic differences and their interaction with environmental factors and especially N fertilization, further research is needed.
