introduction: it has been reported the alkaline response of pancreas to duodenal acidification is partly mediated through duodenal release of h2s, but till now the effect of duodenal acidification on gastric h2s release has not been investigated. therefore, the present study designed to evaluate the effects of duodenal acidification on gastric h2s release and level of mrna expression of cystath...

The twentieth century has witnessed a process of significant transition of the Syrian Christian community in Kerala in terms of its demographic and socio-economic status. In this paper, the transition of the demographic structure is discussed in terms of size, composition, geographic distribution and growth rates and the underlying factors of transition comprising fertility, mortality, and migr...

In 1901, Thomas Hunt Morgan wrote: " The fact that the process of regener-ation is useful to the organism cannot be made to account for its existence in the organism " (Morgan, 1901). Although such words may strike us today as being counter to the general concepts of natural selection, Morgan reached this conclusion after an exhaustive study of regeneration in both plants and animals (Morgan, 1...

Background: Bradford protein assay is popular due to its ease of performance and relative sensitivity. Many researchers and laboratories in Iran use standard assay of Bradford by cuvette. No commercial kit was available for Bradford microplate assay in Iran. Meanwhile, imported Bradford commercial kits are very expensive and have a long delivery time in Iran. Till now no study or document on Br...

Propolis is a resinous hive product Kv bees. The versatile biological activities of propolis, such as its antibacterial, antiviral, fungicidal, anti­ ulcer, immunostimulating, hypotensive and cytosta­ tic properties, as well as its successful clinical applica­ tions [1 — 3] have created an increasing interest in its chemical composition. The last appears to be very complex — the bees collect pr...

Why does regeneration take place in some animals but not others? Increased understanding of gene function is required to dissect the genetics, cell biology, and physiological aspects that make regeneration possible. An unlikely model animal, the planarian Schmidtea mediterranea, is proving valuable in this endeavor.
