Abstract Background In Ethiopia, about 92.3% of all the fuelwood (firewood and/or charcoal) is consumed for cooking, heating and lighting purposes by domestic households and the demand is growing from 10 to 14%. However, there are little/no practical experiences or documented indigenous knowledge on how traditional people identify and select high fuelwood producing plant species with short rotation periods at Boset District. Therefore, the present study was aimed at: (1) selecting and documenting high fuelwood producing plant species at Boset District; (2) identifying major predictor variables that influence the prioritization and selection of species; and (3) develop a Generalized Linear Model (GLM) to predict the selection of species. Methods A total of 96 informants comprising 59 men and 37 women between the ages of 18 and 81 were sampled. Data were collected using structured interviews, guided field walk, discussions and field observations. Results Collected data indicated that 88.5% of the informants involved in firewood collection, while 90% practiced charcoal making. A total of 1533.60 Birr per household on average was earned annually from this activity. A total of 25 fuelwood producing plant species were identified and documented at Boset District. Of these, Acacia senegal, Acacia tortilis and Acacia robusta were the three best prioritized and selected indigenous high fuelwood producing species. Prosopis juliflora, Parthenium hysterophorus, Azadirachta indica, Calotropis procera, Cryptostegia grandiflora, Lantana camara and Senna occidentalis further grouped under introduced fuelwood species. Prediction of GLM assured sampled Kebeles and source of income generated from fuelwood species positively and significantly (p < 0.001) related to selection of species. Higher efficiency to provide energy and heat; little or no smoke or soot; easier to cut and split the wood and easier availability were some of the main selection criteria. Conclusions This study provides valuable information in selecting and documenting of high fuelwood producing plant species for proper management and sustainable use at Boset District. The three most selected species (A. senegal, A. tortilis and A. robusta) should be further evaluated at laboratory to determine their calorific value and combustion characteristics.

Plant Poisoning

Plant poisoning is a health concern in many countries where plants are used either accidently, especially among children, or intentionally for purposes such as assassination, suicide, hunting, fishing and treating various diseases. Presently, despite the implementation of toxicology surveillance systems in many countries, plant poisoning continues to be a preventable cause of morbidity and mortality. In the Aden governorate of Yemen, there are no laws or regulations for the prevention of plant poisoning, despite the existence of several poisonous species in gardens, and as roadside trees planted by the local authority, or growing wildly in public areas. In addition, there is a lack of scientific studies on the risks of these poisonous plants. Therefore, we undertook this study, based on scientific review, to document and illustrate the botanical, geographical and toxicological characteristics of fourteen poisonous plants collected from different districts of Aden governorate. The documented poisonous species (6 species) belong to Apocynaceae followed by Fabaceae (2 species), whereas Aristolochiaceae, Cucurbitaceae, Dracaenaceae, Euphorbiaceae, Meliaceae, and Verbenaceae are represented by one species each. The toxic parts of the majority of studied poisonous species are the whole plant, latex, seeds, and fruits. Cardiotoxicity, cytotoxicity, gastrointestinal toxicity, and inflammation of skin and mucous membrane are the main clinical manifestations. They are caused by varying amounts of plant toxins such as cardiac glycosides in Calotropis procera, Cryptostegia grandiflora, Nerium oleander and Thevetia peruviana, and cytotoxic toxins such as toxalbumins in Abrus precatorius and Ricinus communis, aristolochic acids in Aristolochia bracteolate, and vinca alkaloids in Catharanthus roseus, as well as gastrointestinal toxins such as cucurbitacins in Citrullus colocynthis, and tannins in Caesalpinia pulcherrima. Inflammation of skin and mucous membrane is caused by calcium oxalate crystals in Calotropis procera latex, and soluble protein in Cryptostegia grandiflora latex. Moreover, Azadirachta indica caused a number of toxicities attributed partially to tetranortriterpenoids, while Sansevieria trifasciata toxicity was reported to be low. The significance of this work is to promote the awareness among the local authority to take legal actions against plant poisoning. In addition, it provides the physicians with scientific information for the diagnosis and treatment of poisoning by some plants. It is hoped that this study motivates researchers to conduct further research on poisonous plants throughout Yemen.

The work was intended to investigate the antibacterial activity of the various medicinal plants viz. Calotropis procera, Jatropha curcas, Cryptostegia grandiflora, Clerodendron inermis and Cassia tora, collected from Indore (Madhya Pradesh, India) region. The aim of the study, with an objective, was to evaluate the antimicrobial potentials and to determine the zone of inhibition of extracts of selected plants on some medically important bacterial strains. The antimicrobial activity was determined in the extracts using agar disc diffusion method. Various plant extracts were tested for the antibacterial activities against Bacillus subtilis, Salmonella typhi, Staphylococcus aureus, Escherichia coli and Corynebacterium diphteriae. Zone of inhibition of extracts were compared with that of standards like streptomycin. The outcomes illustrated that the noteworthy inhibition of the bacterial growth was shown against the tested organisms. The phytochemical analyses of the plants were also carried out. The microbial activity of the selected plant was due to the presence of various secondary metabolites. Hereafter, these plants can be used to discover bioactive natural products that may serve as leads in the development of new pharmaceuticals research activities.

В обзоре рассматриваются современные представления об этиологии, патогенезе, факторах риска, диагностике и лечении острого панкреатита после операций на сердце в условиях искусственного кровообращения. Для поиска научных публикаций применяли базу данных PubMed, поисковую систему Google Scholar, а также при статейные списки литературы. Анализ литературы показал, что одной из причин острого панкреатита после кардиохирургических вмешательств является абдоминальная ишемия. При поздней диагностике и несвоевременно начатом лечении он ассоциируется с неблагоприятным прогнозом и высокой летальностью. Чтобы избежать неблагоприятных последствий, необходимы стратификация их риска и определение индивидуальной лечебной тактики. Разработка алгоритма ведения данной категории пациентов позволит стратифицировать их по группам риска и повысить эффективность лечебных мероприятий.

 There is scant research-based evidence on the development and adoption of open access (OA) and institutional repositories (IRs) in Africa, and in Kenya in particular. This article reports on a study that attempted to fill that gap and provide feedback on the various OA projects and advocacy work currently underway in universities and research institutions in Kenya and in other developing countries. The article presents the findings of a descriptive study that set out to evaluate the current state of IRs in Kenya. Webometric approaches and interviews with IR managers were used to collect the data for the study. The findings showed that Kenya has made some progress in adopting OA with a total of 12 IRs currently listed in the Directory of Open Access Repositories (OpenDOAR) and five mandatory self-archiving policies listed in the Registry of Open Access Repositories Mandatory Archiving Policies (ROARMAP). Most of the IRs are owned by universities where theses and dissertations constitute the majority of the content type followed by journal articles. The results on the usage and impact of materials deposited in Kenyan IRs indicated that the most viewed publications in the repositories also received citations in Google Scholar, thereby signifying their impact and importance. The results also showed that there was a considerable interest in Swahili language publications among users of the repositories in Kenya.
