Ureteric peristalsis, which occurs via alternating contraction and relaxation of ureteric smooth muscle, ensures the unidirectional flow of urine from the kidney to the bladder. Understanding of the molecular mechanisms underlying ureteric excitation-contraction coupling, however, is limited. To address these knowledge deficits, and in particular to test(More)
The microcirculation is the site of gas and nutrient exchange. Control of central or local signals acting on the myocytes, pericytes and endothelial cells within it, is essential for health. Due to technical problems of accessibility, the mechanisms controlling Ca2+ signalling and contractility of myocytes and pericytes in different sections of(More)
Mesenchymal stem cells (MSCs) play important roles in tissue repair and cancer progression. Our recent work suggests that some mesenchymal cells, notably myofibroblasts exhibit regulated exocytosis resembling that seen in neuroendocrine cells. We now report that MSCs also exhibit regulated exocytosis. Both a G-protein coupled receptor agonist, chemerin, and(More)
In this review, we give a state-of-the-art account of uterine contractility, focussing on excitation-contraction (electro-mechanical) coupling (ECC). This will show how electrophysiological data and intracellular calcium measurements can be related to more modern techniques such as confocal microscopy and molecular biology, to advance our understanding of(More)
In ureteric microvessels the antagonistic relationship between Ca(2+) signalling in endothelium and Ca(2+) oscillations in myocytes and pericytes of arterioles and venules involves nitric oxide (NO), but the underlying mechanisms are not well understood. In the present study we investigated the effects of carbachol and NO donor SNAP on Ca(2+) signalling and(More)
Transient receptor potential melastatin 8 (TRPM8) is the principal cold and menthol receptor channel. Characterized primarily for its cold-sensing role in sensory neurons, it is expressed and functional in several nonneuronal tissues, including vasculature. We previously demonstrated that menthol causes variable mechanical responses (vasoconstriction,(More)
Mg2+, ATP-dependent Ca2+ accumulation in the rat myometrial mitochondria was investigated in complex experiment using Ca2+ isotope (45Ca2+) and Ca(2+)-sensitive label tetracycline. Monotonous increase of the fluorescence signal, insensitive to thapsigargin (100 nM) was observed with following establishing the stationary state of incubation at 2 min. which(More)
A three years' study was performed regarding the influencing of vaccine therapy in 360 patients affected with diseases caused by bacterial allergy. An evaluation was made concerning the effects obtained by treatment with autovaccines in 110 patients, with stock vaccines in 60 patients, with autovaccines enriched with strain Neisseria meningitidis (N.m) in(More)
Recent advances in pericyte research have contributed to our understanding of the physiology and pathophysiology of microvessels. The microvasculature consists of arteriolar and venular networks located upstream and downstream of the capillaries. Arterioles are surrounded by a monolayer of spindle-shaped myocytes, while terminal branches of precapillary(More)
