M. B., Muslim female, aged 25 years, wife of a doctor and sister of a doctor, on my friendly visit to her family on Gth April, 1942, told me that she had been having a slight temperature between 99? and 100?F. for four days. She had no other complaint except a little pain in the abdomen, especially in both subcostal regions. I told her not to worry, thinking that it was only an attack of sandfl...

A direct method based on oblique projections is adapted to compute the stationary distribution vector of a finite Markov chain. The algorithm can also be used to compute the group inverse of the corresponding generator matrix. It is shown how to update the stationary vector and other quantities of interest when one row of the transition probability matrix is modified. A GTH-like variant that ap...

The endocrine regulation of reproduction in a multiple spawning flatfish with an ovary of asynchronous development remains largely unknown. The objectives of this study were to monitor changes in mRNA expression patterns of three gonadotropin hormone (GTH) subunits (FSHβ, LHβ and CGα) and plasma GTH levels during ovarian maturation of half-smooth tongue sole Cynoglossus semilaevis. Cloning and ...

The Senegalese sole (Solea senegalensis) is a valuable flatfish for aquaculture, but it presents important reproductive problems in captivity. Spawning is achieved by wild-caught breeders but cultured broodstocks fail to spawn spontaneously and, when they do, eggs are unfertilized. To gain knowledge on the physiological basis underlying this reproductive dysfunction, this study aimed at analyzi...

The secretion of gonadotropins (GtH) in goldfish and carp, is stimulated by GtH-releasing hormone (GnRH) and is inhibited by dopamine. Studies with antidopaminergics have demonstrated to be effective in order to stimulate the spermiation and the ovulation in different species of teleosts. The reserpine, a drug that deplets the dopamine, has shown to stimulate the spermiation in the common carp....

Stagnant production, soaring prices, and enhanced imports of pigeonpea (red gram) have been matter of concern to the prime stakeholders in India. A new hybrid pigeonpea breeding technology, developed jointly by the International Crops Research Institute for the Semi-arid Tropics (ICRISAT) and Indian Council of Agriculture Research (ICAR) is capable of substantially increasing the productivity o...

We present a new accurate algorithm (REFUND) for computing the fundamental matrix (or closely related group inverse matrix) of a finite regular Markov chain. This algorithm is developed within the framework of the State Reduction approach exemplified by the GTH (Grassmann, Taksar, Heyman)/Sheskin algorithm for recursively finding invariant measure. The first (reduction) stage of the GTH/S algor...

LPXRFamide (LPXRFa) peptides have been characterized for their ability to inhibit gonadotropin (GTH) release in birds and stimulate growth hormone (GH) release in frogs. However, their involvement in regulating the reproductive hypothalamo-pituitary-gonadal axis in mammals and fish is inconclusive. To study the role of LPXRFa peptides in the regulation of GTH secretion, we cloned tilapia LPXRFa...
