We investigated the properties of an artificial chimeric peptide that contains an Arg-Gly-Asp (RGD)tripeptide, the versatile cell recognition signal of extracellular matrix protein components, coupled to a carboxyl-terminal fragment of the highly specific a-thrombin hibitor, hirudin (residues 53-64): WG-SANGDFEEIPEEYL (RGD-hir~din'~-'~). Hir ~ d i n ~ ~ ' ~ and RGD-hir~din'~-'~ inhibited th...

The two-sample Lepage test, devised for testing equality of the location and scale parameters against the alternative that at least for one of the parameters the equality does not hold, is extended to the general case of k > 1 sampled populations. It is shown that its limiting distribution is the chi-square distribution with 2(k — 1) degrees of freedom. This fc-sample statistic is shown to yiel...

Indian population is well known for its genetic diversity, ethnicity and microdifferentiation process. The present work deals with the distribution of A1A2BO, Rh (D), PTC tasting ability and Red green Colorblindness to study the genetic structure, fitness and microdifferentiation process among different Muslim populations of North India. We have undertaken a survey of the gene frequencies of th...

BACKGROUND Sponges have long been known to be ecologically important members of the benthic fauna on coral reefs. Recently, it has been shown that sponges are also important contributors to the nitrogen biogeochemistry of coral reefs. The studies that have been done show that most sponges are net sources of dissolved inorganic nitrogen (DIN; NH4 (+) and NO3 (-)) and that nitrification, mediated...

Availability and leaching of dissolved inorganic N (DIN = NH4 + NO3) in soil were measured in a periodically flooded forest of the Central Amazon floodplain (v rzea) during one terrestrial phase. Special emphasis was on the effects of a legume and a nonlegume tree species. NH4-N accounted for more than 85% of DIN even at the end of the terrestrial phase although it decreased throughout the expe...
