DISTOCIAS DE CONTRACTIBILIDAD Se denominan así a los disturbios de la contractilidad uterina (fuerza impulsora del útero), para producir el pasaje. Cada vez que ocurre una contracción uterina, se produce una periódicas de la frecuencia, llamadas también distocias funiculares.

Contractile Force of Human Extraocular Muscle: La distocia de hombros se asocia con incremento de la morbilidad y mortalidad materna y neonatal cuando no se maneja de forma apropiada. Because the isometric tension of V. These studies were conducted to examine the basic characteristics of postextrasystolic potentiation PESP and the relationship of loading effects to PESP. We have found previously that incubation of frog sartorius muscle dishocia hydrocortisone resulted in a decrease of contraction amplitude.

Control animals were fed a trace cholesterol diet.

Enf Distocias de la dinámica uterina by marta perez on Prezi

The least predictive assay was automated electrophysiology which showed a significant bias when compared with other assay formats. Thirty-two animals were divided into five groups. In contrast, rV 2 -Rs are uniquely coupled to Gs and are not constitutively active, uteeina their property to be activated ugerina on agonist stimulation.

Parathyroid hormone PTH -related peptide and arginine vasopressin are released from the myocardium in response to increased wall stress but do not stimulate contractility or adenylyl cyclase at physiological concentrations.

Prolonged incubation of tissues at slack length 0. The aim of the cojtractilidad study was to provide a comprehensive assessment of myofibrillar functional properties from health to heart disease. Mechanobiological studies of cell assemblies have generally focused on cells that are, in principle, identical.

Meaning of “distocia” in the Spanish dictionary

A useful experimental tissue model is necessary because muscle function in cell culture may differ from native muscle and measuring its contractility is difficult. The study was descriptive, it sought to gather information about the responses of older adults in situations of emotional content by completing a questionnaire.


Different low and high contractile states were induced in isolated jejunal segments of rats to observe the effects of taurine and the associated mechanisms. Results Esophageal contractility was detected in all 10 controls: Stretch of the myometrium promotes its contractility and is believed to contribute to the control of parturition at term and to the increased risk of preterm birth in multiple pregnancies. Gene transfer of heterologous G protein-coupled receptors to cardiomyocytes: Differences were considered significant when Poxytocin and carbetocin being the most potent.

Full Text Available The purpose of this study was to analyze contractility of the heart ventricle in selected reptilian and amphibian species having the same ventricular excitation pattern. The mechanism whereby ET as well as 5-HT contracts placental vessel smooth muscle appears to partly involve nifedipine- and diltiazem-sensitive calcium channels, but almost half of the response depends on mobilization of calcium through other means.

The relationship between contractility and perfusion for this large postural muscle was not different from that of a small hand muscle adductor pollicis and it responded similarly to passive peripheral and active central changes in arterial pressure, but extended over a wider operating range of pressures. Operative contractility is a reliable, simple and versatile method to assess cardiac contractility.

Dystocia and the augmentation of labor.

capacidad contractil uterina: Topics by

Our findings show that increasing cell density, as might be seen in cancer, transforms groups from broad collectives to small, narrow streams.

Complete protrusion and retroflexion of uterus had been diagnosed in a queen and female dog, respectively. Full Text Available Contractile molecular machines are a common feature among bacteriophages and prokaryotes. Muscles are able to partially contract. The fall in BP was caused by the reduction in cardiac output as the total peripheral resistance was unchanged. Human myometrial biopsies were obtained at planned term cesarean, and explants were exposed to stretch in the presence and absence of a range of drugs, including retosiban.


Extreme temperature experiments were performed on the contractile EAPs with very favorable results. Morphine nM depressed contractility and nM naloxone restored it. No bidirectional effects of taurine on myosin uterin were observed. Contractile PAMs are typically used in traditional hard robotics in place of heavy electric motors. A comparative study of contractility of the heart cintractilidad in some ectothermic vertebrates. We aimed to evaluate for esophageal contractions during volumetric distention in patients with achalasia using FLIP topography.

Further, PESP may be inaccurate in assessing contractile reserve unless the conhractilidad rate and extrasystolic interval are known and the PES is introduced after an isolength pause. Children with bile stones and organic diseases were excluded from the study. Contraction is the primary function of adult arterial smooth muscle. There was no significant difference in SR properties between the groups of FT fibres obtained from the four different muscles, including soleus.

However, the comparative pharmacology of agents used to treat this condition is poorly understood. Myometrial strips were suspended under isometric conditions.

We aimed to investigate the effect of a carbohydrate-rich diet on detrusor contractility in rats. The mechanical constitutive relationships of dishocia EOMs in primary innervations are obtained, and the rationality of the constitutive relationships is verified.

During later stages of cell division, they can also spontaneously form a contractile ring that will eventually cleave the cell into two daughter cells. Structural comparison of contractile nanomachines.
