Advanced Molecular Biologic Techniques In Toxicologic Disease, Jeanine Ward, Gyongyi Szabo, David Mcmanus, Edward Boyer

Gyongyi Szabo

The advancement of molecular biologic techniques and their capabilities to answer questions pertaining to mechanisms of pathophysiologic events have greatly expanded over the past few years. In particular, these opportunities have provided researchers and clinicians alike the framework from with which to answer clinical questions not amenable for elucidation using previous, more antiquated methods. Utilizing extremely small molecules, namely microRNA, DNA, protein, and nanoparticles, we discuss the background and utility of these approaches to the progressive, practicing physician. Finally, we consider the application of these tools employed as future bedside point of care tests, aiding in the ultimate goal of …


Excessive Dietary Calcium In The Disruption Of Structural And Functional Status Of Adult Male Reproductive System In Rat With Possible Mechanism, A K. Chandra, Pallav Sengupta, Haimanti Goswami, Mahitosh Sarkar Dec 2011

Excessive Dietary Calcium In The Disruption Of Structural And Functional Status Of Adult Male Reproductive System In Rat With Possible Mechanism, A K. Chandra, Pallav Sengupta, Haimanti Goswami, Mahitosh Sarkar

Pallav Sengupta, PhD

Calcium is essential for functioning of different systems including male reproduction. However, it has also been reported as chemo-castrative agent. The study has been undertaken to elucidate the effect of excessive dietary calcium on male reproductive system in animals with possible action. Adult male healthy rats fed CaCl2 at different doses (0.5 g %, 1.0 g % and 1.5 g %) in diet for 13 and 26 days to investigate reproductive parameters as well as the markers of oxidative stress. Significant alteration was found (p<0.05) in testicular and accessory sex organs weight, epididymal sperm count, testicular steroidogenic enzyme (Δ5 3β-HSD …
