A felvidéki soltészfalvakról
No full textThe aim of the author in this essay is to analize some terms: more Scultetorum, sub iure Saxonum, iuxta consuetudinem Scepus. She comes to the conclusion that these words usually indicated those „hospes"-\awy which originally were brought into the Hugarian Kingdom by German „hospites" and were completed with Hungarian characteristics. These terms were also used as the name of the elements of the „hospes"-law
Formative synonymia of adjectives in dialects – selected interpretative issue.
No full textAutor prezentuje wybrane problemy analizy odprzymiotnikowych derywatów, które wchodzą w relacje synonimii słowotwórczej. Na przykładzie występujących w gwarach Polski centralnej przymiotników ekspresywnych oraz oznaczających intensyfikację cechy lub jej osłabienie omawia trudności związane z interpretacją znaczenia derywatów oraz funkcji formantów, które je tworzą. Przymiotniki oznaczające wysoki stopień natężenia danej cechy tworzą szeregi synonimów bliskoznacznych, których formanty, pełnią różną funkcję – ekspresywną (np. -uchny, -uśki, -utki, -usi, -usieńki) oraz wzmacniającą i wyolbrzymiającą nazywaną cechę (np. -chny, -achny, -alachny, -aśny, -aśki). Szczególną uwagę zwraca się na kontekst, który odgrywa podstawową rolę w prawidłowym odczytaniu znaczenia przymiotników o znaczeniu cechy niepełnej. Jest on podstawowym narzędziem selekcji materiału, w którym te same formanty (np. -awy, przy-, przy-/-awy) tworzą derywaty wskazujące na osłabienie cechy podstawowej oraz jej nadmiar.The author presents selected issues of an analysis of adjectival derivatives which are parts of formative synonymia. She discusses difficulties with the interpretation of the meaning of derivatives and the function of the formants that create them. The analysis is based on expressive adjectives that indicate intensification and weakening of a feature. These adjectives occur in the dialects of central Poland. The adjectives indicating a high degree of intensity of a given feature result in a number of synonyms whose formants fulfil different functions: expressive (e.g. -uchny, -uśki, -utki, -usi, -usieńki), strengthening and exaggerating (e.g. -chny, -achny, -alachny, -aśny, -aśki). Special attention has been paid to the context that plays a primary role in the understanding of adjectives of an incomplete feature. It is a major tool of selecting the material in which the same formants (e.g. -awy, przy-, przy-/-awy) create derivatives indicating the weakening or excess of the primary feature
Autoimmune polyendocrinopathy type II in a Chinese patient
No full textAutoimmune polyendocrinopathy type II is rarely reported in Chinese patients. A 42-year-old Chinese woman with a history of Hashimoto's thyroiditis and hypogonadotropic hypogonadism presented with pneumonia. During hospitalisation, she went into an adrenal crisis and diabetic ketoacidosis. Subsequent dynamic hormonal tests revealed primary and secondary adrenal insufficiency. She also had pernicious anaemia, possible alopecia areata, and myasthenia gravis. This constellation of multiple endocrine and non-endocrine disorders led to the diagnosis of autoimmune polyendocrinopathy type II. As the syndrome can be lethal, it is important to maintain a high index of suspicion, enabling early diagnosis and the appropriate replacement therapy, to ensure a successful outcome.link_to_subscribed_fulltex
Perspective of students in the Global Citizenship in Dentistry as an international peer learning experience
No full textObjective:
To explore the achievement and perception of dental students in an international peer learning setting via the Global Citizenship in Dentistry (GCD) program.
Methods:
In the GCD program, year-2 dental students from universities in Egypt, Hong Kong, Malaysia, UK, and the United States developed a portfolio of a restorative procedure in simulation laboratory and uploaded to an online platform (https://gcd.hku.hk/). Through the platform, the students left comments on each other's portfolios to share and discuss their knowledge and experiences on restorative dentistry. This study invited students from Hong Kong in 2018–2019 to complete an open-ended questionnaire to explore their experience on the GCD program. The feedback was compiled and analyzed.
Results:
All 71 year-2 students completed the questionnaire. Their most dominant comments were positive feelings about learning different clinical principles and methods from universities abroad. The students also enjoyed the cultural exchange from the comfort of their own devices. Other recurrent comments included the improvement of the skills of communication and comments on the peers’ work in a professional manner. The students were enthusiastic about being able to apply their critical thinking in evaluating their work. They shared their learning barriers, including the extra time needed for the program, some unenthusiastic responses from groupmates, and delayed replies from peers. They made suggestions to remove the barriers in the learning process of the GCD program.
Conclusion:
Students generally welcomed the GCD program and benefitted from the global academic exchange, development of critical thinking, enhancing professional communication skills, as well as opportunities of cultural exchange.link_to_subscribed_fulltex
Dosage requirement of erythropoietin can be reduced with more frequent administration
No full textIn short-term studies, once weekly and twice weekly dosing regimens of erythropoietin (EPO) have both been shown to be effective in correcting anaemia in dialysis patients. However, the optimal dosing frequency has yet to be determined. The long-term effects of EPO given by more frequent divided doses in 10 stable haemodialysis patients were studied. The patients achieved a stable haemoglobin level for at least 3 months prior to the study. The frequency of administration was altered from 4000 units once weekly to 2000 units twice weekly in seven patients, from 4000 units once every 10 days to 2000 units twice weekly alternating with 2000 units once weekly in two patients, and from 4000 units fortnightly to 2000 units once weekly in one patient. After the conversion, EPO dosage was adjusted in order to maintain the haemoglobin at the preconversion level. At the end of 28 weeks, the mean haemoglobin level remained unchanged. However, the mean dosage requirement of EPO reduced from 3400 units per week to 2500 units per week (P = 0.019). This represents a significant 26% reduction in dosage and cost. It was concluded that subcutaneous administration of frequent small doses of EPO is a more cost-effective way of correcting anaemia in haemodialysis patients.link_to_subscribed_fulltex
Review of anaesthetic management for cataract surgery in transplant recipients
No full text\ua9 The Author(s) 2020. The prevalence of transplantation is on the increase worldwide. Corneal transplantation is the most common form of human donor transplantation. Transplantation of other organs and bone marrow is established treatment for various end-organ failure and many haematological conditions, respectively. Success and survival of these patients have increased with advances in immunosuppression. Unfortunately, these patients are susceptible to cataract formation as a consequence of immunosuppressive therapy and accelerated progression of several diseases. Topical anaesthesia and regional ophthalmic blocks are ideal for cataract surgery in cooperative adults. General anaesthesia may be required in children, for extremely anxious or claustrophobic adults and for complex surgery such as simultaneous cataract and corneal transplantation. The perioperative anaesthetic management of cataract surgery in a transplant recipient is no different to a standard technique in a healthy adult, but additional challenges are posed by the underlying pathology necessitating transplantation, function of the transplanted organ, physiological and pharmacological problems of allograft denervation, side-effects of immunosuppression, risk of infection and potential for rejection. This narrative review summarises optimal anaesthetic management in transplant recipients undergoing cataract surgery
Misalignment Between Perceptual Boundaries and Weight Categories Reflects a New Normal for Body Size Perception
No full text© 2021, The Author(s). Combatting the current global epidemic of obesity requires that people have a realistic understanding of what a healthy body size looks like. This is a particular issue in different population sub-groups, where there may be increased susceptibility to obesity-related diseases. Prior research has been unable to systematically assess body size judgement due to a lack of attention to gender and race; our study aimed to identify the contribution of these factors. Using a data-driven multi-variate decision tree approach, we varied the gender and race of image stimuli used, and included the same diversity among participants. We adopted a condition-rich categorization visual task and presented participants with 120 unique body images. We show that gender and weight categories of the stimuli affect accuracy of body size perception. The decision pattern reveals biases for male bodies, in which participants showed an increasing number of errors from leaner to bigger bodies, particularly under-estimation errors. Participants consistently mis-categorized overweight male bodies as normal weight, while accurately categorizing normal weight. Overweight male bodies are now perceived as part of an expanded normal: the perceptual boundary of normal weight has become wider than the recognized BMI category. For female bodies, another intriguing pattern emerged, in which participants consistently mis-categorized underweight bodies as normal, whilst still accurately categorizing normal female bodies. Underweight female bodies are now in an expanded normal, in opposite direction to that of males. Furthermore, an impact of race type and gender of participants was also observed. Our results demonstrate that perceptual weight categorization is multi-dimensional, such that categorization decisions can be driven by ultiple factors.University of Tennessee Health Science Centre; Brunel University London
Changes of ATP and ADP in cultured astrocytes under and after in vitro ischemia
No full textA very large body of evidence from in vivo studies has been accumulated on a link between the change of energy and cell survival/apoptosis. Using an in vitro ischemia model, we have previously shown that ischemia could induce apoptosis in astrocytes. In this study, we utilized the same in vitro model to investigate changes in ATP and ADP levels in cultured astrocytes and attempted to demonstrate an energy-cell death linkage. Astrocytes remained unaltered after 2 hr of ischemia but were moderately or severely damaged after 4 or 6-8 hr, respectively. The astrocytes that survived various lengths of in vitro ischemic incubation retained their ability to produce ATP after ischemia. Both ATP and ADP levels were increased in astrocytes that remained alive under in vitro ischemia for over 6 hr. The largest decline in the percent of viable astrocytes during ischemia corresponded well to the reduction in ATP and ADP levels in these cultures.Biochemistry & Molecular BiologyNeurosciencesSCI(E)PubMed14ARTICLE121663-16682
