Müller Cell Reactivity in Response to Photoreceptor Degeneration in Rats with Defective Polycystin-2
BACKGROUND Retinal degeneration in transgenic rats that express a mutant cilia gene polycystin-2 (CMV-PKD2(1/703)HA) is characterized by initial photoreceptor degeneration and glial activation, followed by vasoregression and neuronal degeneration (Feng et al., 2009, PLoS One 4: e7328). It is unknown whether glial activation contributes to neurovascular degeneration after photoreceptor degenerat...
INTRODUCTION Intervertebral discs (IVD) are swollen structures which support substantial static and dynamic loads. Load-carriage is achieved by hydrostatic pressurization of the fluid-filled nucleus pulposus (NP) contained by the ultra-low hydraulic permeability of the endplates and mechanically strong annulus fibrosis (AF). During the diurnal loading cycle, fluid is slowly wrung out in a proce...
We have used the isolated planar cortex of sea urchin eggs to examine the role of osmotic forces in exocytosis by morphological and physiological methods. Electron micrographs of rotary-shadowed replicas show an en face view of exocytosis and demonstrate fusion of cortical vesicles to the underlying oolemma upon addition of calcium. Freeze-fracture replicas of rapidly frozen cortices reveal spe...
Antibiotics are added to semen extenders to take care of heavy microbial load, however, their continuous use poses a constant threat of developing antibiotic resistance by the common microbes present in the semen. Our hypothesis was that natural honey, having antibacterial activity and rich in fructose could replace the use of antibiotics and fructose in the semen extender. Twenty-four ejaculat...
The volume-sensitive chloride current (ICl,swell) is found in the mammalian myocardium and is activated by osmotic swelling. The goal of this study was to examine the importance of the tyrosine kinases focal adhesion kinase (FAK) and Src kinase in cardiac ICl,swell regulation. Neonatal rat ventricular myocytes were cultured on collagen membranes and infected with adenovirus expressing beta-gala...
