PEROXISOME PROLIFERATOR-ACTIVATED receptor (PPAR)is one of the three PPAR subtypes (PPAR , PPAR / , and PPAR ) that are ligand-activated transcription factors that belong to the nuclear hormone receptor superfamily (7, 12, 13, 19). Far beyond the stimulation of peroxisome proliferation in rodents after which they were initially named, PPARs control the transcription of large number of genes inv...

Partitioning of rainfall into evapotranspiration and runoff is controlled by climate and catchment characteristics. The degree of control exerted by these factors varies with the spatial and temporal scales of processes being modelled. Understanding individual hydrological processes and their relationships with climatic and catchment characteristics is an important step in predicting catchment ...

water changes information in the hydrological system, in time and space, as an environmental issue takes heed of managers and decision makers in watershed management and river engineering, which can be addressed by using spatially distributed modeling. in this study simulation of water balance components in taleghan mountainous watershed is performed using the spatially distributed hydrological...

Total body water and tonicity is tightly regulated by renal action of antidiuretic hormone (ADH), reninangiotensin-aldosterone system, norepinephrine and by the thirst mechanism. Abnormalities in water balance are manifested as sodium disturbances--hyponatremia and hypernatremia. Hyponatremia ([Na+ < 136 meq/ l]) is a common abnormality in hospitalized patients and is associated with increased ...

Many medical and surgical emergencies are complicated by derangement of water and electrolyte balance, the successful management of which depends upon the rapid assessment of essential clinical and laboratory data, and the prompt institution of a certain pre-arranged routine of treatment. An attempt is made in this review to illustrate the application of physiological principles to specific cli...

s modem respiratory intensive care becomes A increasingly well defined as a subspecialty, it is important to critically evaluate the effect of various types of ventilatory support on the patient as a whole. One aspect of the general care of the respiratory patient with which the physician must deal is fluid and electrolyte balance. The original report of Sladen et al,' suggesting that sodium an...

Dietary electrolyte balance is calculated as the sum of Na and K minus Cl and is expressed in mEq/kg of diet. The manipulation of dietary electrolyte balance (dEB) to enhance lactation and reproductive performance in dairy cattle and laying hens is not a new concept. However, the effects of dEB on reproduction and lactation in sows have not been elucidated. Thus, our objective for the experimen...

[Purpose] This research was designed to find out how the so-called "dynamic balance" is affected by doing different types of warm up exercises. In particular, the research is focused on the difference in the effect on dynamic Balance of warming up in water versus on the ground. [Subjects and Methods] Twenty healthy adults were the subjects of this study, with 10 people assigned each to two grou...

Simultaneous measurements of all major electrolytes including HCO3(-) and H+ as well as water demonstrated that fluids absorbed by the anterior intestine of the marine gulf toadfish under in vivo-like conditions on an overall net basis are hypertonic at 380 mOsm and acidic ([H+] = 27 mM). This unusual composition of fluids absorbed across the intestinal epithelium is due to the unusual intestin...

Many studies have shown that subjects lose significant amounts of body mass, fat mass as well as fat-free mass, during a climb to and/or a stay at high altitude. Altitude-induced weight loss is mainly caused by malnutrition due to hypoxia-related satiety, independent of acute mountain sickness.
