Thyroid Stimulating Hormone (TSH) plays an important role the growth process, chronic hormone deficiency conditions will spur incidence of stunting. The purpose study was determine effect supplementary food formula substitution sea urchin gonads (Diadema Setosum) on hormone, height weight stunted toddlers S...

We report here a rare case of bilateral pure gonadoblastoma which accounts for only 0.2% of all ovarian tumours seen at Universiti Kebangsaan Malaysia from 1980 to 1987. This tumour occurred in an 18 year old Chinese "female" who presented with primary amenorrhoea. Examination showed a phenotypic female with poorly developed external gentalia. Exploratory laparotomy revealed a hypoplastic uteru...

glands. From this result, they indicated that the precocious sexual maturity was caused in the mouse by anuran anterior pituitary substances. It seems to the author that there would be no reference available,concerning the response of mammalian gonads to anterior pituitary hormones of pisces. Hence, in this paper effect of the hypophyseal gonadotropic hormones of tunny(Makaira marlina) to the g...

Yolk sac tumor (YST) is a common malignant primitive germ cell tumor that often exhibits differentiation into endodermal structures. They most commonly occur in childhood and adolescence and are rare after the age of 40 years. Derived from the yolk sac during the embryonic period, YSTs can occur in the gonads and germ cells because the tumor cells migrate from the yolk sac toward the gonads. He...

Ghrelin is an endogenous ligand of the growth hormone secretagogue receptor. It is mainly secreted by stomach cells but has also been shown to be present in the hypothalamus, pituitary, gonads and many other organs. Ghrelin is a regulator of energy homeostasis and GH secretion. Many studies have been done examining the influence of ghrelin on different organs. Ghrelin may play an important role...

Belly colouration, gonad carotenoid concentration and skin transparency were quantified in gravid Gobiusculus flavescens, as well as in females of five sympatric gobies where belly ornamentation has not been described. Although G. flavescens females did, indeed, have far more colourful bellies than the other species, this could only in part be explained by a high concentration of total gonad ca...

Stem cells have enormous potential for therapeutic application because of their ability to self-renew and differentiate into different cell types. Gonads, which consist of somatic cells and germ cells, are the only organs capable of transmitting genetic materials to the offspring. Germ-line stem cells and somatic stem cells have been found in the testis; however, the presence of stem cells in t...

This paper describes the occurrence of digenetic Rhipidocotyle santanaensis Lunaschi, 2004 in Brazil. This parasite was found in the liver, heart, gonads, intestine, pyloric caeca, stomach, swim bladder and cavity of Acestrorhynchus lacustris (Lütken, 1875) from the Batalha River, São Paulo State, with higher incidence in gonads and digestive tract. The parasite specimens found in this study sh...

The male reproductive system includes the gonads (testes), a series of specialized ducts (the epididymis, ductus deferens, ejaculatory duct, and urethra), accessory glands (the seminal vesicles, prostate, and bulbourethral glands), and the external genitalia (penis and scrotum). The female reproductive system includes the gonads (ovaries), derivatives of an embryonic system of ducts (the uterin...

Gigantidas platifrons is one of the most dominant deep-sea mussels in cold seeps ecosystems South China sea. Studies have shown that are a gonochoristic species, however, little known about molecular mechanisms sex determination G. . In this study, RNA-seq and WGBS methylation analysis were performed on adult gonads to identify potential sex-related genes generate comprehensive mussels. A total...
