Phospholipid hydroperoxide glutathione peroxidase (PHGPx), an antioxidative selenoprotein, is modulated by estrogen in the testis and oviduct. To examine whether potential endocrine disrupting chemicals (EDCs) affect the microenvironment of the testes, the expression patterns of PHGPx mRNA and histological changes were analyzed in 5-week-old Sprague-Dawley male rats exposed to several EDCs such...

Males are at greater risk of cardiovascular and renal disease than are females. For example, male spontaneously hypertensive rats (SHR) have higher blood pressures than females. Androgens have been strongly implicated in the hypertension of male SHR, because castration attenuates the hypertension. This study determined whether the androgen receptor plays a role in hypertension in male SHR and w...

Endocrine disruption compounds (EDC) are known to affect reproduction, development, and growth of exposed organisms. Although in vertebrates, EDCs mainly act through steroid receptors (e.g. androgen estrogen receptors), their absence many invertebrates suggests the involvement another biological pathway endocrine effects. As retinoid signaling is present almost all Metazoa its gastropods (i.e. ...

Approximately 65% of patients with prostatic cancer treated by the combination therapy using a gonadorelin (LHRH) agonist or orchidectomy in association with the antiandrogen Anandron complained of a delay in recovering vision after bright illumination (sun, television, bright light). Detailed ophthalmological examination revealed an increase in the photostress recovery time to an average of 9 ...

In this update, bicalutamide (Casodex, Zeneca Pharmaceuticals) has been confirmed as an effective, well-tolerated and convenient non-steroidal anti-androgen for advanced prostate cancer. Preclinical and clinical studies have indicated its potential as monotherapy, with quality of life advantages compared with castration. A head-to-head comparison with flutamide, where both anti-androgens were u...

A protocol for the ab initio crystal structure determination of powdered solids at natural isotopic abundance by combining solid-state NMR spectroscopy, crystal structure prediction, and DFT chemical shift calculations was evaluated to determine the crystal structures of four small drug molecules: cocaine, flutamide, flufenamic acid, and theophylline. For cocaine, flutamide and flufenamic acid,...

A comprehensive screening of the more recent DFT theoretical approach to structural analysis is presented in this section of theoretical structural analysis. The chemical name of 2-methyl-N-[4-nitro-3-(trifluoromethyl)phenyl]-propanamide is usually called as Flutamide (In the present study it is abbreviated as FLT) and is an important and efficacious drug in the treatment of anti-cancer resista...

Fluid and solute transport across the epithelium of the male excurrent duct is important for sperm maturation and storage. Aquaporin 9 (AQP9), which allows permeation of water and neutral solutes, is abundant throughout the male reproductive tract, where it is expressed at the apical membrane of rat epididymal principal cells as early as at 1 week of age. We evaluated the effect of neonatal exp...
