Abstract:
To study the interactions between insulin and contraction on the skeletal muscle glucose transport system, the hindquarters of male rats were perfused in the absence of insulin, in the presence of insulin (30 mU/ml), during contractions induced by sciatic nerve stimulation, or during contractions plus insulin. Compared with control preparations, rates of glucose uptake in the perfused hindquarter were increased by 2.5- and 2.6-fold in the insulin and insulin plus contraction groups, respectively, but not significantly increased in the contraction only preparations. After perfusion, soleus and

Collagen lattices containing bovine retinal pericytes (RPs), vascular smooth muscle cells (VSMCs), pulmonary microvessel endothelial cells (PMECs), or aortic endothelial cells (AECs) were prepared and contraction was quantitated by measuring the resulting change in lattice area. VSMCs were the most efficient at lattice contraction followed by RPs and then PMECs. AECs did not contract the lattices. To document further that these observations represent contraction, cells were grown on inert silicone rubber sheets. Substratum wrinkling was indicative of tension development and quantitated as perc

Intercellular communication between germ cells and neighboring somatic cells is essential for reproduction. Caenorhabditis elegans oocytes are surrounded by and coupled via gap junctions to smooth muscle-like myoepithelial sheath cells. Rhythmic sheath cell contraction drives ovulation and is triggered by a factor secreted from oocytes undergoing meiotic maturation. We demonstrate for the first time that signaling through the epidermal growth factor-like ligand LIN-3 and the LET-23 tyrosine kinase receptor induces ovulatory contractions of sheath cells.

Introduction. Plasma membrane calcium ATPase is a constitutive structure of cells that functions as a high affinity system of releasing Са2+ ions from the cytoplasm and ensures a long-term maintenance of the basal concentration of these cations in the state of dormancy. Currently, there are no satisfactory means for the pharmacological correction of plasma membrane calcium ATPase function. Thus, elaboration, synthesis, and study of substances with the targeted impact on plasma membrane calcium ATPase are topical issues.

Several disease states, including hypertension, are associated with elevations in plasma endothelin-1 (ET-1) and variable changes in vascular contraction to ET-1. The spotting lethal ( sl) rat carries a deletion of the endothelin-B (ETB) receptor gene that prevents expression of functional ETB receptors, resulting in elevated plasma ET-1. On a normal diet, these rats are normotensive and thus provide an opportunity to study the vascular effects of chronically elevated ET-1 in the absence of hypertension.

Abstract:
Body contouring with liposuction has evolved significantly from the early approach of simply debulking excess fatty tissue, to affecting the mechanical properties of different tissue types and layers. Operative paradigms have been expanded to apply energy-based technologies intraoperatively to provide more uniform aspiration, selective fatty tissue emulsification in soft and fibrous body areas, minimize trauma to nerves and vessels, expose the fibrous septal network, reduce operator fatigue and help deliver smooth shapes with less discomfort and bruising. Advanced refinements with the delivery of monopolar and bipolar radiofrequency energy for soft tissue heating have been shown to reduce the residual soft tissue laxity that often follows voluminous fat removal. The Renuvion® (Apyx™ Medical, Clearwater, FL) radiofrequency powered helium plasma technology introduces an emerging concept in which the delivery of subdermal thermal energy preferentially coagulates the fascia and fibrous septal network through a conductive helium plasma stream seeking the path of least resistance, which in turn results in collagen contraction and tissue shrinkage that permits re-draping of the skin and enhanced definition. The physics and mechanics of Renuvion® subdermal soft tissue coagulation will be presented, along with clinical applications that have provided the authors more contouring finesse and has augmented liposuction outcomes.

Abstract:
Gastric peristaltic contractions are the basis for emptying of solids from the stomach. These events begin in the mid to high corpus region, develop into a ring around the stomach, and spread down the length of the stomach to the pylorus. The pressure wave resulting from gastric peristalsis pushes the contents of the stomach toward the pyloric sphincter, but a nearly simultaneous contraction of the ring of muscle in the pyloric canal and the terminal antrum ultimately forces much of the food in the retrograde direction, toward the body of the stomach. Sheer forces that develop as a result of this forceful retropulsion cause mechanical disruption of solid particles. Repetitive peristaltic contractions (e.g., in the human these events occur about 3 times per minute), over a period of time, reduces ingested foods to small particles. The action of gastric peristalsis in the distal stomach facilitates emptying and the reduced particle diameter aides in chemical digestion of foods in the small intestine. Pathophysiological conditions that disrupt or disorganize gastric peristalsis can impair or delay normal gastric emptying. Gastric peristaltic contractions result from depolarization of the plasma membranes of smooth muscle cells. For many years it has been known that gastric muscles display periodic (or rhythmic) electrical activity in which membrane potential oscillates between negative potentials and more depolarized levels. The oscillations in membrane potential are known as electrical slow waves (see Color Figs. 2.1 and 2.2 in separate color insert). Slow waves are generated within the tunica muscularis of the proximal corpus along the greater curvature of the stomach, and these events spread around the circumference and down the stomach to the pylorus. A greater velocity of propagation around the stomach than down the stomach causes development of a ring of excitation, and this is the electrical basis underlying gastric peristaltic contractions. Studies have shown that electrical slow waves are generated by specialized pacemaker cells, known as interstitial cells of Cajal (ICCs). The main pacemaker ICCs in the stomach form a dense network of electrically coupled cells between the circular and longitudinal muscle layers of the corpus and antrum.

Abstract:
The posterior pituitary produces arginine vasopressin, which has a key role in fluid homeostasis, and oxytocin, which stimulates uterine contraction during birth and ejection of milk during lactation. Cranial diabetes insipidus is the passage of large volumes of dilute urine due to vasopressin deficient synthesis and/or release. The most common cause is lesions of the neurohypophysis or the hypothalamic median eminence damaging the magnocellular neurons. MRI of the neurohypophysis is required to delineate the cause. Mild polyuria can be managed simply by ensuring adequate fluid intake; treatment with the long-acting vasopressin analogue, desmopressin is used for more severe cases. The syndrome of inappropriate antidiuresis is diagnosed when there is hyponatraemia with hypotonic plasma, inappropriate urine osmolality, and urinary sodium more than 20 mmol/litre, together with no evidence of volume overload or hypovolaemia, and normal renal, adrenal, and thyroid function.

Abstract:
Molecular mechanisms and targets of cyclic guanosine monophosphate (cGMP) accounting for vascular smooth muscles (VSM) contractility are reviewed. Mathematical models of five published mechanisms are presented, and four novel mechanisms are proposed. cGMP, which is primarily produced by the nitric oxide (NO) dependent soluble guanylate cyclase (sGC), activates cGMP-dependent protein kinase (PKG). The NO/cGMP/PKG signaling pathway targets are the mechanisms that regulate cytosolic calcium ([Ca2+]i) signaling and those implicated in the Ca2+-desensitization of the contractile apparatus. In addition to previous mathematical models of cGMP-mediated molecular mechanisms targeting [Ca2+]i regulation, such as large-conductance Ca2+-activated K+ channels (BKCa), Ca2+-dependent Cl− channels (ClCa), Na+/Ca2+ exchanger (NCX), Na+/K+/Cl− cotransport (NKCC), and Na+/K+-ATPase (NKA), other four novel mechanisms are proposed here based on the existing but perhaps overlooked experimental results. These are the effects of cGMP on the sarco−/endo- plasmic reticulum Ca2+-ATPase (SERCA), the plasma membrane Ca2+-ATPase (PMCA), the inositol 1,4,5-trisphosphate (IP3) receptor channels type 1 (IP3R1), and on the myosin light chain phosphatase (MLCP), which is implicated in the Ca2+-desensitization. Different modeling approaches are presented and discussed, and novel model descriptions are proposed.

Evidence against this concept was provided by Zucker-Franklin, who showed that platelet plasma membrane is different from that of the MK (freeze-fracture, membrane antigens). Several authors have described contractile processes in MK’sWe have performed detailed electronmicroscopic studies of the numerous small MK's of a subject with congenital macrothrombocytopenia. In the young granular MK’s a central zone with organelles and a thick peripheral zone without organel

Abstract In this study, the influence of the direction of the plasma-induced flow generated by a plasma actuator (PA) on the jet flow was investigated. Nozzles equipped with two types of PAs to generate forward (Type A) and backward (Type B) flows were used in this investigation. At a duty ratio was 50%, for both Types A and B, the fluctuation due to the plasma-induced flow yielded the most stable fluctuation near the nozzle exit. In the case of the Type B PA, the centerline velocity was increased by the contraction of the main flow near the nozzle exit due to the influence of the backflow. Ad

Abstract:
Abstract An investigation has been undertaken on the analysis of residual stress in glass coatings during plasma spraying. Theoretical analysis and in-situ experimental measurements show that the residual stresses in glass coatings are particularly sensitive to the heat input from the plasma flame, since this can raise the temperature to above the glass transition temperature. Control of the spraying parameters enables the quench stress of splats to be relaxed by the end of the spraying and the only significant remaining source of stress derives from the differential contraction between the co

Abstract:
Review question / Objective: The aim of this meta-analysis is to evaluate the efficacy and safety of intraoperative infusion of combined 5-fluorouracil and low molecular weight heparin (LMWH) for the prevention of postoperative proliferative vitreoretinopathy in patients with retinal detachment. Condition being studied: Postoperative proliferative vitreoretinopathy (PVR) is the primary cause of failure of retinal reattachment surgery. 5-fluorouracil (5-FU) inhibits the proliferation of fibroblasts, and suppresses collagen contraction. On the other hand, heparin reduces fibrin exudation, and in
