In rats, androgens in adulthood regulate the morphology of motoneurons in the spinal nucleus of the bulbocavernosus (SNB), including the size of their somata and the length of their dendrites. There are conflicting reports about whether androgens exert similar influences on SNB motoneurons in mice. We castrated or sham-operated C57BL6J mice at 90 days of age and, thirty days later, injected cho...

Vascular smooth muscle cells (VSMCs) play important roles in cardiovascular disorders and biology. Outlined in this paper is a step-by-step procedure for isolating aortic VSMCs from adult C57BL6J male mice by enzymatic digestion of the aorta using collagenase. The plating, culturing, and subculturing of the isolated cells are discussed in detail along with techniques to characterize VSMC phenot...

Prenatal viral infection has been associated with development of schizophrenia and autism. Our laboratory has previously shown that viral infection causes deleterious effects on brain structure and function in mouse offspring following late first trimester (E9) administration of influenza virus. We hypothesized that late second trimester infection (E18) in mice may lead to a different pattern o...

OBJECTIVES/HYPOTHESIS The murine model has been used extensively to model and study human deafness. Technical difficulty in the surgical approach due to the small size of the tympanic bulla and a robust stapedial artery has limited its application for studies of cochlear implantation and electrical stimulation. We describe a minimally traumatic, stapedial artery-sparing approach to the round wi...

Two-dimensional gel electrophoretic analysis of cell lysates from Brucella abortus 2308 and the isogenic hfq mutant Hfq3 revealed that the RNA binding protein Hfq (also known as host factor I or HF-I) is required for the optimal stationary phase production of the periplasmic Cu,Zn superoxide dismutase SodC. An isogenic sodC mutant, designated MEK2, was constructed from B. abortus 2308 by gene r...

Abstract Background and Aims Voluntary exercise is of utmost importance to avert a plethora diseases ameliorate other conditions, such as neuromuscular diseases, however in some occasions, the inflammation can be exacerbated by intense physical activity. The folic acid kidney disease model key interest since it non-invasive leads conspicuous fibrosis. Our main objective was determine influence ...
