In vertebrates, circulating androgen levels are regulated by the hypothalamic-pituitary-gonadal (HPG) axis through which the brain controls the gonads via the pituitary. Androgen levels ultimately depend on factors including season, temperature, social circumstance, age, and other variables related to reproductive capacity and opportunity. Previous studies with an African cichlid fish, Astatoti...

BACKGROUND/AIMS Cytomegalovirus (CMV) surveillance and preemptive therapy is a widely-used strategy for preventing CMV disease in transplant recipients. However, there are limited data on the incidence and patterns of CMV disease during the preemptive period. Thus, we investigated the incidence and pattern of tissue-invasive CMV disease in CMV seropositive kidney transplantation (KT) and hemato...

Abstract Background Heart valve regurgitation is common in patients with end-stage renal disease (ESRD). However, there are no data on the fate of mitral (MR) and aortic (AR) after kidney transplantation (KT). In this study, we sought to investigate regression or progression rates MR AR KT ESRD. Moreover, aimed explore clinical echocardiographic factors associated undergoing KT. Methods Among 1...

Our purpose was to assess the relationship between serum fibroblast growth factor 23 (FGF23) and left ventricular function, carotid intima-media thickness (CIMT) and laboratory features in children on peritoneal dialysis (PD). The study population consisted of 17 patients (11 female; median age 7.83 years, range 0.66-17.75) undergoing PD for 22 months (range 2-98). Serum FGF23, serum phosphorus...

In the peacock blenny, Salaria pavo, a species with courtship sex-role reversal, smaller, younger males mimic the courtship behavior and the nuptial coloration of females in order to get access to nests during spawning and to parasitize egg fertilization from nest-holder males. Later in their life, sneakers transform both morphologically and behaviorally into nest-holder males. In the present p...

INTRODUCTION There are no established indications for Liver transplant (LT) in patients with a Klatskin tumour (KT) due to the differences in the published results. OBJECTIVE To report on our patients who have non-disseminated unresectable KT and who were given a LT, and to compare results with those of patients who have had tumour resection and those who have not. PATIENTS AND METHOD We ha...
