Hemophagocytic lymphohistiocytosis secondary to epstein-barr virus reactivation in a patient with COVID-19
No full textHemophagocytic lymphohistiocytosis (HLH) in coronavirus disease 2019 (COVID-19) is a recognized complication of severe illness. However, this phenomenon has been reported most often in the setting of acute infection. Here we present a case of a patient with a history of severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) infection that subsequently developed HLH weeks after treatment of COVID-19 and discharges from the hospital. Upon re-admission, work-up demonstrated the patient was experiencing Epstein-Barr virus (EBV) reactivation. As EBV infection is a known etiological trigger of HLH, this case provides an alternative mechanism for HLH seen in patients with a history of COVID-19 infection who present after the resolution of acute symptomatology. </p
The SIMUS method addresses two important MCDM drawbacks: Getting different results for the same problem, and the inability to model complex scenarios
No full textThis paper considers that actual methods for addressing MODM or MCDM scenarios share two shortcomings along these lines: a) Failing to show equal results when different MCDM methods solve the same problem. b) Inability to replicate actual scenarios, by not taking into account existing conditions, and thus, producing an approximate representation of reality, which obviously, renders not reliable results. This paper shows how the SIMUS method addresses these two shortcomings.</p
An assessment of indigenous knowledge of apitherapy in the Oromia region, Ethiopia
No full textApitherapy is the use of bee products such as honey, pollen, propolis, royal jelly, bee venom, and wax is used to prevent or treat illness and promote healing. The objectives of this study are to assess and document indigenous knowledge on the medicinal values of bee products in Ethiopia and generate baseline information on indigenous practices of the medicinal value of beehive products for further study. This study was conducted in beekeeping potential areas of Oromia Regional state by selecting seven zones and from each zone two districts and a total of 14 districts (Woreda) based on their potential for beekeeping, the existence of long-aged bee-keepers and accessibility. using a purposive sampling method and questionnaires were distributed to the elders and well-known traditional healers of the study areas. In answering the questionnaires 22-100 ages dwellers or respondents participated. The survey was conducted in 7 zones namely Jimma, Ilu ababora, West wollega, East wollega, East Shoa, West shoa, and Buno Bedele. Simple descriptive statistics were used to analyze the data obtained by collected questionnaires. The result of the study showed that 49.3% of Apis mellifera honey and 31.9% of stingless bee honey, majorly used bee products for apitherapy, and 70.3 % of the bee products used using traditional collection method. According to this study’s results, the traditional drug was prepared from honey in liquid form which comprises the biggest portion mark of 63.4% of respondents. The majority of the respondents strongly agree with bee products as a treatment for different diseases such as asthma, cough, common cold, TB, and wounds. A major challenge faced during using of bee products as medicine is the absence of awareness of apitherapy as it was reported by 28.8%. of the respondents. Thus, it can be concluded that bee products are well-known apitherapy in the Oromia region and it was recommended that awareness creation of bee products as apitherapy and further research on the medicinal value of beehive products for confirmation as medicine for different diseases since it may be a solution for various diseases resisting modern drugs.</p
Experimental in vitro modeling of hematopoiesis by using diffusion chambers of an original design
No full textOne of the most important tasks of biotechnology and regenerative medicine is to achieve long-term expansion of hematopoietic stem cells. One of the promising approaches to optimizing the cultures of hematopoietic cells is the creation of a microenvironment in the form of feeder stromal layers, which allows for the reproduction of the combination of soluble cytokines and growth factors necessary for hematopoiesis and promotes an increase in their proliferation [1,2].</p
Histological characterization of sexual reproduction in the coral Pocillopora damicornis (Coelenterata: Scleractinia) from the Red Sea
No full textThe scleractinian coral is common along the Red Sea coast, and its reproductive mode and period of reproduction were assessed using histological preparations. the sexuality, and reproductive mod timing of reproductive of pocillopora damicornis from adjacent to the fringing reefs of the Ubhur Creek in the Red Sea, were assessed using a serial histological section. Sexual reproduction in pocillopora damicornis a shallow water hermatypic coral was studied from December 2011 to November 2012. pocillopora damicornis is a simultaneous hermaphrodite with ovary and testis in the project into the body cavity on the same mesentery. Sperm and eggs were usually released simultaneously from the same polyp. The onset of the reproductive period of pocillopora damicornis was found to be limited (April to May). In the number of eggs and testes observed in this period, the gonads were found in the polyps. The pocillopora damicornis egg size ranged from 49.80 µm (in March) to 125.0 µm (in May). Four stages were chosen, to reflect very immature ovaries, the early stages of oocyte development, ova near maturity, and mature ova, and also four distinct stages of sperm development were identified. The state of gonads development (eg. testis and eggs) was measured by a calibrated eyepiece micrometer of a compound light microscope. Zooxanthellae were presented in the mature oocytes in pocillopora damicornis. This study aimed to examine the reproduction mode and timing of pocillopora damicornis.</p
The theory of centralized aerobic-anaerobic energy balance compensation and the right posture
No full textFor over four centuries the posture was under very different points of view. The theory of centralized Aerobic-Anaerobic Energy Balance Compensation (CAAEBC) gives an additional angle of consideration, associated with the concept of brachiocephalic arterial blood flow access to the rhomboid fossa. This helps to understand the requirements of the set of physical exercises, that will be able to keep the posture training simultaneously with the healthcare.</p
Features of the use of ungulates by oxpeckers (Buphagus) in central Kenya
No full textA detailed multi-year observational study of Red-Billed (RB) oxpecker (Buphagus erythrorhynchus) and yellow-billed (YB) oxpecker (B. Africanus) occurrence on a range of ungulate species was performed in two Kenyan national parks. Surprisingly observation of over 2100 individual Kongoni, in group sizes of 1 to > 50, revealed a total absence of oxpeckers, of either species, on Kongoni (Alcephalus buselaphus: subfamily Alcephalinae) in Nairobi National Park (NNP), although it was one of the most common bovid species present. There is no population of A. buselaphus at the second study site in central Kenya, Lake Nakuru National Park (LNNP). By contrast, the Impala (Aepyceros melampus), a smaller species, whose taxonomic status is phylogenetically ambiguous, but is widely considered to have evolved relatively recently in Africa, was a frequent oxpecker host in both NNP (29% of animals observed) and LNNP (12.9% of individual animals observed. Two species of gazelle Thompson’s gazelle (Gazella rufifrons)) and Grant’s gazelle (G. granti), subfamily Gazellinae, which were present in both parks but in relatively low abundance, were also not observed to host oxpeckers. The reason for these bovid subfamilies, apparently not being utilized as oxpecker hosts in central Kenya, is unclear and requires further research. </p

Medical and scientific research in Libya. Position on sustained developmental goals
No full textUNESCO recommendation on science and scientific researchers aims to support scientific research and science as tools for achievements of the 17 sustainable development goals (SDGs). Countries are responded differently to these recommendations. In this article we tried to assess the polices and measures taken by Libya State as a developing country to meet these recommendations. The assessment reveals big shortcomings in the Libyan government’s response to UNESCO recommendation on science and scientific researchers. </p
Stormwater management a case study of Nashik city
No full textStormwater management means to manage surface runoff. Stormwater management can reduce the runoff of rainwater. It includes controlling flooding and reducing erosion to improve water quality. This Strategy used in our Nasik city (Untwadi Road Signal) to prevent the impacts of Stormwater. We know that, in rainy season the water is flow over the ground surface. This rainwater does not have any suspended solid, it collects in drainage which flow by the force of gravity and then it discharges near lake or river. Urbanization reduces the infiltration rate of lands it causes of the flooding it occurs scouring and waterlogging problem. So, it is necessary to identify area of problem and suggest BMPs (Best Management Practices) techniques. </p
