Cryptocleidoid plesiosaurs from the Upper Jurassic are well known from the Oxford Clay (Callovian) of the United Kingdom. The plesiosaurs of the nearly coeval Sundance Formation (Oxfordian) of North America are poorly known, but are thought to include two cryptocleidoid taxa: Pantosaurus striatus and Tatenectes laramiensis. Here we present two specimens recently recovered from the Bighorn Basin...

The present paper deals with the piscicidal and muricidal (mice killing effect) activities of latex extract of Euphorbia royleana against freshwater snakehead fish, Channa punctatus and Swiss albino mice Mus musculus. Calculated values of lethal concentration (LC and LC ) showed that latex extract is toxic 50 90 against both the experimental animal. The toxicity of latex extract against freshwa...

Nuvan (DDVP) is a member of organophosphorus compounds. It is extremely toxic to insects and is widely used as insecticides. Nuvan has been taken for the acute toxicity to a fresh water fish Channa punctatus LC50 value calculated for the acute toxicity, which were 0.024 ml/L. Histopathological study of kidney and liver after 24hr, 48hr, 72hr and 96hr exposure to acute toxicity of Nuvan. Treatme...

In the marine environment, sessile cyanobacteria have developed chemical strategies for protection against grazers. turn, herbivores to circumvent these defenses and in certain cases even take advantage of them as shelter from their own predators. This is case Stylocheilus striatus, a sea hare that feeds on Anabaena torulosa, cyanobacterium produces toxic cyclic lipopeptides laxaphycin B family...

Three patients presented with an asymptomatic longitudinal pigmented band in a nail. A junctional melanocytic naevus in the nail matrix was suspected; this was confirmed by histological examination in each case. Differential diagnosis and management are discussed, together with a review of the literature. Local excision is considered to be the treatment of choice.

Comparative study was conducted to observe the efficacy of different feeding regimes on growth of Channa punctata. Six iso- proteinous diets were prepared by using different agro industrial by-products. Maximum weight gain was recorded with diet having 66.75% rice bran, 11.50% mustard cake, 23.0% groundnut cake, 5% molasses, 1.5% vitamin-mineral mixture and 0.5% salt with specific growth rate o...
