253 Mathilde will be the next asteroid to be visited by a spacecraft (NEAR). Mathilde is an exceptional slow and complex rotatorwith a period of 17.4 days (Mottola et al., 1995). Binzel et al. (1996) have obtained the first spectrum ofMathilde in the visible range. To search for any variation on the asteroid surface, we have performed several observations in the visible range at the European So...

Telomeres comprise the protective caps of natural chromosome ends and function in the suppression of DNA damage signaling and cellular senescence. Therefore, techniques used to determine telomere length are important in a number of studies, ranging from those investigating telomeric structure to effects on human disease. Terminal restriction fragment (TRF) analysis has for a long time shown to ...

Among the 14 known endemic countries in the Eastern and Southern Africa subregion, mapping has been completed in seven and is in progress in four. Five countries have active mass drug administration programmes, and up to six rounds of mass treatment have been given in some of the implementation areas. Three countries have initiated disability prevention and management as part of their programme...

cucumber mosaic virus (cmv) is one of widely-spread viruses of plants with the broadest host range encompassing over 1200 species. one major limiting factor for detection of the virus is unavailability of the virus-specific antibodies especially in developing countries. recombinant dna technology facilitates antibody preparation without requiring special equipment. in this study, coat protein (...

background and objective: streptococcosis/lactococcosis is the cause of high morbidity and mortality in aquaculture sector and to date a number of species of streptococcus and lactococcus genera including s. iniae, s. agalactiae, s. dysagalactiae, s. parauberis, s. feacalis, l. garvieae and l. lactis have been discriminated as the cause of disease in aquatic animals. despite the use of diagnost...
