The sexual system of the decapod (caridean) shrimp Lysmata is protandric simultaneous hermaphroditism (PSH). Individuals first mature as males (male phase = MP) and then when older (larger) change to the external phenotype of female carideans (female phase = FP). However, unlike purely protandric carideans, Lysmata FPs retain reduced male gonadal tissues and ducts, and are able to mate nonrecip...

Kentucky, at his clinic which was a veritable beehive of activity almost entirely devoted to the surgery of the hand. I remember that it was located near about the Mohammad Ali Avenue, who recently passed away because that is where he was born as Casius Clay. Years before I first met Dr. Kleinert, I had served as a resident at the Grace Hospital in Detroit (1972) where they used to speak about ...

Kinase Suppressor of Ras (KSR) is a conserved protein that positively regulates Ras signaling and may function as a scaffold for Raf, MEK, and ERK. However, the precise role of KSR is not well understood, and some observations have suggested that KSR might act in a parallel pathway. In C. elegans, ksr-1 is only required for a specific Ras-mediated process (sex myoblast migration) and is a nones...

How true! God never meant his machine to be mended by ordinary mortals. It was made with built in mechanisms needed for the rescue measures. Modern living has robbed most of the “civilised” world of the many benefits of an active lifestyle. Man has become sedentary what with all the gadgets for assisting him in every walk of life. Even housewives have become more or less sedentary. This is a cu...

Genetic relationships among Carica papaya cultivars, breeding lines, unimproved germplasm, and related species were established using amplified fragment length polymorphism (AFLP) markers. Seventy-one papaya accessions and related species were analyzed with nine EcoRI-MseI primer combinations. A total of 186 informative AFLP markers was generated and analyzed. Cluster analysis suggested limited...

Nature, 230, 167-168. usual finding in true hermaphroditism with the exception of a limited few who demonstrate a 46,XY chromosomal complement or a variant due to mosaicism. The diagnosis of true hermaphroditism requires the demonstration of both ovarian an...

The objective of the present study was to determine the length (mm) for sex transformation of hermaphroditism in white spot grouper Epinephelus coeruleopunctatus as a basis for developing breeding technology. Fish sampling was carried out between April and October 2013 in Padang City waters, Indonesia. A total of 56 white spot groupers were recorded during the study; of these 22 were male, 28 f...
