Background. Studies have reported a higher preva-lence of hypogonadism in men with type 2 diabetes mellitus (T2DM) than non-diabetic men. The pattern T2DM using gonado-tropin-releasing hormone (GnRH) stimulation test Sub-Saharan Africa is unknown. Objective. This study was conducted to determine the prevalence and Nigerian T2DM. Methods. A cross-sectional involving 358 179 as controls. Androgen...

The greater amberjack Seriola dumerili is a large teleost fish with rapid growth and excellent flesh quality, whose domestication represents an ambitious challenge for aquaculture. The occurrence of reproductive dysfunctions in greater amberjack reared in captivity was investigated by comparing reproductive development of wild and captive-reared individuals. Wild and captive-reared breeders wer...

Occasionally, nurses perform phlebotomy via intravenous catheters, especially to improve efficiency in short-stay or procedural units. The intent of this practice is to reduce the number of venipunctures and thus increase patients’ comfort. However, obtaining laboratory specimens from peripheral intravenous catheters may hemolyze the specimens, and can even dislodge catheters and necessitate re...

Identifying the sources of variation in traits of larvae is one of the first steps in interpreting the role of phenotypic variation in recruitment. We examined the contributions of geographic source and parentage to phenotypic variation in offspring traits in a gadid, Microgadus tomcod, from 2 contrasting yet nearby locations. Adults were collected from the Hudson River (HR), a polluted riverin...

Patterns of reproductive ontogeny in four species coral reef wrasses (F: Labridae) Hemigymnus melapterus, fasciatus, Cheilinus fasciatus and Oxycheilinus digramma were investigated. Populations each sampled from two island groups the central Great Barrier Reef (GBR), Australia, reefs Philippines. These three sampling locations span 30° latitude. The GBR Philippine experience biologically signif...

A high sensitivity human chorionic gonado-tropin (hCG) detection was conducted by a tapered side-polished (TSP) optical fiber sensor. Experimentally, the TSP sensor made side polishing short section of single mode to D shape structure and tapering small diameter ( $ < 10~\mu \text{m}$ in experiments). By functionalizing ...

MAMMALS, as a rule, are described as having melanocytes of neural crest origin confined almost entirely to the skin. Of the organs other than skin which have been described as possessing melanocytes are portions of the gonado-genital apparatus of the Opossum (Burns, 1939), and, in the house mouse, tissues of the nictitans, the meninges of the brain, the parathyroids, the thymus and harderian gl...

 The paper focuses on some of the biological characteristics of golden grey mullet, Liza aurata in Iranian waters of the Caspian Sea. Samples of commercial catch of mullet obtained by means of beach seine fishing cooperatives along the Iranian coasts of Caspian Sea (2007-2008) as monthly interval. Samples subjected to biometric measurement to specify their biological characteristics. The male/f...
