| In order to amalgamate research findings on HIV/AIDS in Nigeria as well as the trend of the infection in a concise manner, we reviewed published articles on the HIV/AIDS situation in Nigeria. We categorized this review into several subheadings. The HIV prevalence rate has continued to rise steadily from less than 0.1% in 1987, to 5.8% in 2001, with a slight decrease in 2003 to 5.0%. Although the knowledge about HIV and its mode of transmission is widespread, it is however disheartening to note that this did not result into appreciable attitudinal change and behavior modification among Nigerians. Both HIV-1 and HIV-2 have been identified in Nigeria, with HIV-1 being the predominant type. Furthermore, several subtypes like subtypes A, B, C, G and J have been... |

| The paper sets out the agenda for reviewing models of decision making in the context of farmers’ use of seasonal climate forecasting. Such forecasts have been framed in terms of shifts in cumulative distribution functions of yields or gross margins. Typically they have been applied to choices about crop variety, crop type, time of planting or level of fertiliser application. Fundamental questions are: how do farmers conceptualise and make use of the information contained in seasonal climate forecasts? Do our models of decision making represent well the way in which these decisions are made? |

| This work provides a review about the biotechnological production of citric acid starting from the physicochemical properties and industrial applications, mainly in the food and pharmaceutical sectors. Several factors affecting citric acid fermentation are discussed, including carbon source, nitrogen and phosphate limitations, pH of culture medium, aeration, trace elements and morphology of the fungus. Special attention is paid to the fundamentals of biochemistry and accumulation of citric acid. Technologies employed at industrial scale such as surface or submerged cultures, mainly employing Aspergillus niger, and processes carried out with Yarrowia lipolytica, as well as the technology for recovering the product are also described. Finally, this review... |

| Temperate Australia sits between the heat engine of the tropics and the cold Southern Ocean, encompassing a range of rainfall regimes and falling under the influence of different climatic drivers. Despite this heterogeneity, broad-scale trends in climatic and environmental change are evident over the past 30 ka. During the early glacial period (similar to 30-22 ka) and the Last Glacial Maximum (similar to 22-18 ka), climate was relatively cool across the entire temperate zone and there was an expansion of grasslands and increased fluvial activity in regionally important Murray Darling Basin. The temperate region at this time appears to be dominated by expanded sea ice in the Southern Ocean forcing a northerly shift in the position of the oceanic fronts and... |

| Cocos nucifera (L.) (Arecaceae) is commonly called the “coconut tree” and is the most naturally widespread fruit plant on Earth. Throughout history, humans have used medicinal plants therapeutically, and minerals, plants, and animals have traditionally been the main sources of drugs. The constituents of C. nucifera have some biological effects, such as antihelminthic, anti-inflammatory, antinociceptive, antioxidant, antifungal, antimicrobial, and antitumor activities. Our objective in the present study was to review the phytochemical profile, pharmacological activities, and toxicology of C. nucifera to guide future preclinical and clinical studies using this plant. This systematic review consisted of searches performed using scientific databases such as... |

| Date is the most popular fruit in middle-east countries. However, the date production process is accompanied by a substantial increase of loss during picking, storage, commercialization and conditioning process. Date and their byproducts have many essential elements for the growth of microorganisms. Thus, they can be converted into value-added compounds through biotechnology. In this paper, date and their processing byproducts used as substrates for producing value-added products such as organic acids, exopolysaccharide, antibiotics, date flavored probiotic fermented dairy, bakery yeast, etc, were reviewed. |

| The raninid genus Cyrtorhina Monod, 1956, is revised and restricted to Cyrtorhina granulosa Monod, 1956, from West Africa. A new genus, Flaberhina, is established for C. balabacensis Serène, 1971 from the Philippines and New Caledonia. Despite their superficial similarities, the two genera can easily be separated by the structures of the carapace, eye, antenna, pterygostome, thoracic sternum, pleon and penis. The taxonomy of the subfamily Cyrtorhininae Guinot & Ng, 2020, which contains both fossil and extant taxa, is also reviewed. |

| Human immunodeficiency virus type 1 (HIV-1) and type 2 (HIV-2) are the causative agents of AIDS. HIV-2 is prevalent at moderate to high rates in West African countries, such as Senegal, Guinea, Gambia, and Cape Verde. Diagnosis of HIV-2 is made with a positive HIV-1/HIV-2 ELISA or simple/rapid assay, followed by one or two confirmatory tests specific for HIV-2. Following CD4+ T cell counts, HIV-2 viral burden and clinical signs and symptoms of immunodeficiency are beneficial in monitoring HIV-2 disease progression. Although non-nucleoside reverse transcriptase inhibitors are ineffective in treating HIV-2, nucleoside reverse transcriptase inhibitors and protease inhibitors can be effective in dual and triple antiretroviral regimens. Their use can decrease... |

| Invasion biology is well-positioned epistemologically, theoretically and practically to address the challenge of being both scientifically and socially relevant. Yet, how well are we achieving these two dimensions of academic inquiry and impact? We explored this issue by a) surveying Argentine invasion biology practitioners (students, scientists and managers) to determine the types of collaborations they report and their stated preferences regarding research thematic priorities (autecology, impacts, management, patterns/distribution, presence/absence, processes/mechanisms, policy, social), and b) reviewing the invasion biology literature in Argentine Patagonia to establish research productivity, the publications' taxonomic, methodological (review,... |

| Ecological biogeography studies the factors that define the spatial distribution of species in the present time. This review summarises recent contributions on ecological biogeography. Most recent articles report environmental factors such as temperature, humidity and salinity as key elements in the ecological biogeography of many species (followed by other organisms and genetic characteristics). Molecular data indicate that some "unexplainable" ranges are artifacts caused by taxonomic misidentification (several species erroneously classified as a single species). Island biogeography theory is often adequate for conservation management, and the new neutral model of ecological biogeography does not fit all species on which it has been tested. Global warming... |

| The research on plant genetic resources is essential for the conservation of genetic diversity and accessions' divergence studies, as a basis for plant breeding. Aiming to know the state of art in this subject, a historical survey was carried out in Revista de Olericultura and in Horticultura Brasileira, from 1961 to 2006, searching for papers dealing with vegetable crops genetic resources. In each of the papers, the species studied, first author institution, publication year, applied software, number of accessions and descriptors, and the multivariate techniques used were registered. Based on these characteristics, papers were grouped using multivariate analysis. Sixty-one papers dealt somehow with genetic resources in the time covered by the survey, from... |
