Activity of xanthine oxidase, levels of lipid peroxidation and ascorbic acid were studied in African land snail (Achatina marginatus) from two sites with different pollution potentials. Lipid peroxidation was significantly higher in the snails from the polluted site compared to the value obtained from the same species from the control site. Similarly, the activity of xanthine oxidase in the sna...

This paper is the first taxonomic account of the hydroid orders Anthoathecatae and Leptothecatae from the Caribbean and Pacific coast of Costa Rica. All specimens are currently stored at the reference collection of the Museo de Zoología, Escuela de Biología, Universidad de Costa Rica. Sixteen hydroid species are recorded: Eudendrium carneum, Pennaria disticha, Acryptolaria longitheca, Plumulari...

The larval morphology of Hypsiboas leptolineatus was studied. The tadpole has an ovoid body in lateral view, wider than deep; snout rounded with dorsal reniform nostrils; spiracle sinistral with lateral wall attached to body; anal tube dextral; tail fins convex with acuminate tip; oral disc ventral; labial tooth row formula is 2(2)/3(1); moderately developed beaks with serrated jaw sheaths.

Despite the increased social and financial burden associated with autism spectrum disorder (ASD), no particular treatment for this illness has been identified. A detailed examination of prior trials conducted to treat revealed that nutrition intervention was commonly utilised as an additional method therapy. Indeed, early detection nutritional deficiencies metabolic problems, together appropria...

The genetic variation in Eumeces latiscutatus from the main islands of Japan and the northern Ryukyus was investigated and compared with that of its close relatives (E. okadae and E. marginatus) using allozyme data. All three samples from the northern Tokara Island Group, currently identified as E. latiscutatus, were shown to belong to E. marginatus and not to E. latiscutatus. The non-monophyly...
