Woodward-Prevost reaction of alkenes with iodine and cobalt(II) acetate in acetic acid is reported. The reaction is facile and α-iodoacetates are obtained from both acyclic and cyclic alkenes in high yields within 15-55 min

Interactive Learning Paper Model of Inguinal Canal

The inguinal region is one of the most complex anatomic areas of human body even though it has been the subject of great interest to anatomists and surgeons because of its clinical importance. The aims of the study are to: 1. provide a simplification and in-depth understanding of the complex and confusing inguinal canal anatomy. 2. incorporate time-effective method in learning. 3. provide revision for coursework at any time and place. This study took place during the 2008–2009 academic year. The anatomical diagrams were prepared with the Microsoft word 2007 and printed on three A-4 papers. The inguinal canal was constructed using ordinary scissors and glue. The efficacy of the model construction is evaluated by testing 10 questions regarding the anatomy of inguinal canal before(pre-test) and after(post-test) doing the construction. The 5-point scale questionnaire was used to elicit the students’ views on different teaching methods in our university. The questionnaire with free comments section was completed by 62 second-year medical students (response rate 60.19%). Ninety six students performed the construction with most completing it within one hour. Scores on the anatomy pre-test and post-test were compared. The mean pre-test score was 8.406/10 and the mean post-test score was 9.309 /10. It was found that there was a significant increase in post-test score (P.05) in the 5-points scale questionnaire. We concluded that the 3-D paper model provides the opportunity to learn and correlate the spatial relations among the inguinal structures in a short period of time especially when taking constraints of time and the availability of other resources into account. Moreover, this model is inexpensive and easy to construct and a valuable supplement to conventional teaching methods

Case studies in anatomy: upper limb

Anatomy, as a part of the medical school curriculum, has always been recognized as an essential foundation for the clinical sciences. It forms a basis for the study of the normal structure for the subsequent study of surgery, medicine, pathology and the other clinical disciplines. In recent decades, despite the decrease in the number of hours students spend in an anatomy course, teaching methods in anatomy have improved. The major shift has been towards integration of clinical problems into the anatomy course. Problem based learning (PBL) has proved to be a very successful method for teaching medical students not only in basic sciences but also in developing problem solving skills and interpersonal relationships. The specific objectives listed in the following pages are intended to encourage students to actively take part in deriving the answers from the cases. Each case study is based on the clinical presentations, in which the detail has been re-focused to draw attention to specific anatomical regions. This book, emphasizing the applied aspects can be used as a supplement to existing classes in Gross Anatomy. This suite of programs attempts to bridge the gap between pre-clinical and clinical medicine. This book is not intended to be a replacement for a good textbook. It has been constructed.....not to save the student from taking the trouble to learn clinical anatomy but to encourage the student to take the trouble and save the taking of unnecessary trouble. We hope that this document should serve as the benchmark for anatomical knowledge and Medical students (preclinical and clinical), Allied health science students (physiotherapy students) and those who study this book will find it worthful

Transformer-Based Multi-Task Learning for Crisis Actionability Extraction

Social media has become a valuable information source for crisis informatics. While various methods were proposed to extract relevant information during a crisis, their adoption by field practitioners remains low. In recent fieldwork, actionable information was identified as the primary information need for crisis responders and a key component in bridging the significant gap in existing crisis management tools. In this paper, we proposed a Crisis Actionability Extraction System for filtering, classification, phrase extraction, severity estimation, localization, and aggregation of actionable information altogether. We examined the effectiveness of transformer-based LSTM-CRF architecture in Twitter-related sequence tagging tasks and simultaneously extracted actionable information such as situational details and crisis impact via Multi-Task Learning. We demonstrated the system’s practical value in a case study of a real-world crisis and showed its effectiveness in aiding crisis responders with making well-informed decisions, mitigating risks, and navigating the complexities of the crisis

Electron microscopic study of esophageal epithelium in non-erosive reflux disease

Introduction: Non-erosive reflux disease (NERD) is the most common phenotype of gastro esophageal reflux disease (GERD). Dilated intercellular spaces (DIS) in prickle cell layers are considered as early signs of acid damage to the esophageal epithelium. Objectives: The objective of this study was to explore DIS in both superficial and prickle cell layer of the esophageal epithelium of NERD patients and normal controls by using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Material and methods: The study group included 5 normal controls and 8 NERD patients with reflux symptoms, normal mucosa on endoscopy and positive 24-hour pH monitoring. Specimens were taken 5 cm above the Z line during gastroduodenoscopy and then routinely processed for both SEM & TEM studies. The nature of intercellular spaces between superficial cells and prickle cell layers were viewed by TEM and SEM respectively. Results: We found out that cellular attachments in the superficial cells differ significantly between the normal controls and patients with NERD (p value 0.007). Morphometric analysis of TEM microphotographs showed that the mean intercellular space diameter values of NERD patients were significantly ( two times) higher than that in normal controls (p<0.001). Conclusions: We can conclude that SEM study on DIS in esophageal surface cells is not a useful diagnostic test for differentiating between normal and NERD patients but TEM study in prickle cell layer is a promising diagnostic finding of early damage of esophageal epithelium
