A simple, reliable method for the in vitro cultivation of snapping turtle embryos was demonstrated. This technique was used to study somite formation in explants containing segmental plates. Segmental plates formed a full complement of somites whether the neural tube or the neural tube and notochord was present. Explanted snapping turtle segmental plates formed an average of 6.6 +/- 1.2 somites...

Recent research has suggested that contaminants in the environment may influence sex differentiation and reproductive endocrine function in wildlife. Concentrations of organochlorine contaminants (total polychlorinated biphenyls, pesticides) were higher in the blood plasma of snapping turtles from contaminated sites than in those from reference sites. The ratio of the precloacal length to the p...

The active parts of 11 medicinal plants were analyzed for physico-chemical evaluation, phytochemical determination and antioxidant activity. The physico-chemical evaluation revealed that highest water soluble extractive was from Origanum vulgare (38%), highest chloroform extractive was from Psoralea corylifolia (21%); highest ethanolic extractive was that of Acorus calamus (11%) and the highest...

In continuation of Nepalese medicinal plant screening research, we have examined the antibacterial property of 40 methanol crude extracts in vitro using disc diffusion method against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Bacillus subtilis. Overall, 95 % of the extracts showed antibacterial activity against at least one Gram-negative bacteria and 90 % of the extract...

Four species of Tephritoidea, three from genus Anastrepha: A. obliqua (Macquart), A. sororcula Zucchi and A. serpentina (Wiedemann), and one from genus Ceratitis, C. capitata (Wiedemann) were compared based on puparium morphology and application of the Heteroduplex Mobility Assay (HMA). Puparia were characterized for the first time using the spiracular posterior plate morphology. Application of...

Although neuro-fuzzy models and other similar modeis have great flexibility they also have drawbacks, especially for systems which have high uncertainty associated . This paper points out which are the major drawbacks of neuro-fuzzy models and proposes a methodology to design fault detectors in uncertain systems using neuro-fuzzy models. The coolíng coil of an air-conditioning system is used as...

A review of world literature on ajamline has been attempted; almost two third of the work is available in the German language. Ajmaline was isolated from rauwolfia serpentina, by Dr. Salimuzzaman Siddilui, and named after Hakim Ajmal Khan who who has used products of rauwolfia as antihypertentive and cardiac sedative. Antiarrhythmic effects of ajmaline are due to depression of atrioventricular ...
