Transmission blocking malaria vaccines are aimed to block the development and maturity of sexual stages of parasite within mosquitoes. The vaccine candidate antigens (Pfs25, Pfs48/45, Pfs230) that have shown transmission blocking immunity in model systems are in different stages of development. These antigens are immunogenic with limited genetic diversity. Pfs25 is a leading candidate and curre...

Background: Due to lack of detailed standards of sexual maturity in individuals with Intellectual, sensory and motor disability in Iran and the importance of timing of onset of puberty in these individuals, a study is necessary. By knowing the onset of puberty, physiologic and behavioral changes can be traced in these people, as well as the potential impact of the puberty on the underlying dise...

In this study, the reproductive biology of chub population in Hafik Lake was investigated. 242 samples were caught between April and November 2009. The age of S. cephalus samples were found to range between I-VIII in addition, 153 of them were female and 89 were male. Their fork lengths changed between 114-332 mm, and body weights were between 22.5 and 550.3 g. Male specimens were determined t...

this study was carried out to determine the effects of lactobacillus plantarum on chemical compositionand nutritive value of whole-plant corn (wpc) ensiled at different stages of maturity. based on local routinepractice, wpc was harvested at three stages of maturity as follows: (1) two weeks before routine harvestingtime; (2), one week before routine harvesting time and (3), routine harvesting ...

—Most anurans exhibit sexual size dimorphism (SSD). This morphological variation between the sexes may be attributed to different ages at maturity, growth rate, or longevity. We present the first data on age structure and growth pattern of Hypsiboas cordobae using skeletochronology, and analyze SSD considering age-specific differences in body size based on 71 individuals. Snout-vent length (SVL...

The general assumption that brain size differences are an adequate proxy for subtler differences in brain organization turned neurobiologists toward the question why some groups of mammals such as primates, elephants, and whales have such remarkably large brains. In this meta-analysis, an extensive sample of eutherian mammals (115 species distributed in 14 orders) provided data about several di...

Abstract We present a detailed histological study of long bones from an ontogenetic series Mussaurus patagonicus , early sauropodomorph the Lower Jurassic Argentina. Twenty bones, including humeri, femora and fibulae, obtained 13 individuals different body sizes were sampled for analysis. In general terms, cortical bone is formed by well vascularized fibrolamellar parallel fibred bone. Except s...
