to study the population structure of decapods in the intertidal zone of bushehr rocky shores, some random sample collection from four rocky and rubble shores of bushehr were done using a 50×50 quadrates sampling unit, in four successive seasons from autumn 2009 to summer 2010. totally 8 speciesbelonging to 5 family of decapods were identified and counted. in the whole course of sample collectio...

The original description of erythromelalgia of Mitchell has been separated into three distinct disease entities of aspirin responsive erythromelalgia in thrombocythemia, incurable congenital dominant primary erythermalgia (PE), and aspirin resistant secondary erthermalgia. Aspirin responsive platelet-mediated erythromelalgic and thrombotic processes in the end-arterial circulation of toes or fi...

We have characterized a novel dominant allele of the sex-determining gene her-1 of Caenorhabditis elegans. This allele, called n695, results in the incomplete transformation of XX animals into phenotypic males. Previously characterized recessive her-1 alleles transform XO animals into phenotypic hermaphrodites. We have identified five new recessive her-1 mutations as intragenic suppressors of n...

The paper wasp Polistes dominulus is unique among the social insects in that nearly one-third of co-foundresses are completely unrelated to the dominant individual whose offspring they help to rear and yet reproductive skew is high. These unrelated subordinates stand to gain direct fitness through nest inheritance, raising the question of whether their behaviour is adaptively tailored towards m...

The p53 tumor suppressor gene is commonly altered in human tumors, predominantly through missense mutations that result in accumulation of mutant p53 protein. These mutations may confer dominant-negative or gain-of-function properties to p53. To ascertain the physiological effects of p53 point mutation, the structural mutant p53R172H and the contact mutant p53R270H (codons 175 and 273 in humans...
