Rat atrial natriuretic peptides inhibit oxygen consumption by rat kidney.
The inhibitory effect of high and low molecular weight native and synthetic rat atrial peptides on oxygen consumption in isolated rat kidney mitochondria and slices was measured. Oxygen consumption by mitochondria was measured in the presence of succinate and/or adenosine diphosphate, furosemide, and low and high molecular weight native and synthetic rat atrial peptides. After the addition of s...

متن کاملDemecolcine-induced enucleation of sheep meiotically maturing oocytes.
The objective of this study was to investigate the possible effect of demecolcine, a microtubule-disrupting reagent, on induced enucleation (IE) of sheep meiotically maturing oocytes. Immunofluorescent staining with anti-tubulin antibodies was used to examine the spindle status of the oocytes. When the oocytes with intact germinal vesicles (GV) were cultured in the medium containing various con...
متن کاملMicrotubule and microfilament organization in maturing human oocytes.
Various stages of immature human oocytes were imaged for microtubule, microfilament and chromatin organization. After germinal vesicle breakdown, a small microtubule aster was observed near the condensed chromatin. The asters appeared to elongate and encompass the condensed chromatin. At metaphase I stage, microtubules were detected in the meiotic spindle. The meiotic spindle in metaphase II wa...
متن کاملZinc Availability Regulates Exit from Meiosis in Maturing Mammalian Oocytes
Cellular metal ion fluxes are known in alkali and alkaline earth metals but are not well documented in transition metals. Here we describe major changes in the zinc physiology of the mammalian oocyte as it matures and initiates embryonic development. Single-cell elemental analysis of mouse oocytes by synchrotron-based X-ray fluorescence microscopy (XFM) revealed a 50% increase in total zinc con...
