The role of coaches in promoting anti-doping education among athletes is well researched in the western world. The present study examined the role of Physical Education (P.E.) teachers in anti-doping education in Ghana under doping practices, knowledge of anti-doping control and the importance of doping education in training programmes among student-athletes. Semi-structured interviews involving eleven P.E. teachers aged 31-46 who coached all the sporting disciplines in Senior High Schools-football, handball, netball, hockey, volleyball, table tennis, badminton and athletics were conducted. Based on the preliminary results, additional information was requested from 10 student-athletes on the use of doping products and the harmful effects. The interviews were transcribed, and the data were analysed thematically. The findings revealed that although coaches and athletes are aware of the effects of doping, the effort to promote anti-doping education have been met with resistance as students claimed P.E. teachers are not health professionals. To be recognised as the best, P.E. teachers were also found culpable of aiding students to use banned performance-enhancing drugs during competitions. A worrying picture of the present study is the sale of drugs to people especially the youths without prescriptions. This has not led only to loss of lives, but to an increase in doping cases, as students can easily have access to drugs that can be used in doping. The present study proposes recommendations and suggestions to the political stakeholder, based on its findings.

Response evaluation criteria in solid tumors (RECIST) are a method used to evaluate and document the response to cancer treatment in solid tumors. The availability of a new class of immuneoncology drugs has resulted in the need to modify RECIST criteria methodology. The first leadership immuno-oncology network (LION) master course brought together experts in oncology and immuno-oncology. Six questions were put to the experts and their opinion, supporting evidence, and experience were discussed to arrive at a practical consensus recommendation. n this nascent field, the availability of a practical consensus recommendation developed by experts in the field is of immense value to the community oncologist and other health-care consultants.

Background:: Tibolone is a synthetic steroid commercialized by Organon under the brand name Livial (Org OD14), which is used in hormone therapy for menopause management and treatment of postmenopausal osteoporosis. Tibolone is defined as a selective tissue estrogenic activity regulator (STEAR) demonstrating tissue-specific effects on several organs such as brain, breast, urogenital tract, endometrium, bone and cardiovascular system. Aims:: This work aims to (1) present an overview of important published literature on existing methods for the analysis of tibolone and/or its metabolites in pharmaceutical formulations and biological fluids and (2) to conduct a critical comparison of the analytical methods used in doping control, pharmacokinetics and pharmaceutical formulations analysis of tibolone and its metabolites. Results and conclusions: : The major analytical method described for the analysis of tibolone in pharmaceutical formulations is High Pressure Liquid Chromatography (HPLC) coupled with ultraviolet (UV) detection, while Liquid Chromatography (LC) or Gas Chromatography (GC) used in combination with Mass Spectrometry (MS) or tandem mass spectrometry (MS/MS) is employed for the analysis of tibolone and/or its metabolites in biological fluids.

AbstractAnatomy is the key to accurate imaging interpretation. It is essential for radiologists to thoroughly understand the normal anatomy and spatial relationships of the stomach and duodenum to accurately localize the site of abnormality. In this article, we describe in detail the gross and applied radiological anatomy of the stomach and duodenum, and the current role of various radiological investigations (including barium studies, endoscopic ultrasonography, computed tomography, and magnetic resonance imaging) in the evaluation of the diseases involving the stomach and duodenum.

In this article, I review a cross-section of research in socio-hydrology from across disciplines in order to better understand the current role of historical-archival analysis in the development of socio-hydrological scholarship. I argue that despite its widespread use in environmental history, science and technology studies, anthropology, and human geography, archival methods are currently underutilized in socio-hydrological scholarship more broadly, particularly in the development of socio-hydrological models. Drawing on archival research conducted in relation to the socio-hydrology of coastal Guyana, I demonstrate the ways in which such scholarship can be readily incorporated into model development.
