Prostaglandin E(2) is a major renal cyclooxygenase metabolite of arachidonate and interacts with four G protein-coupled E-prostanoid receptors designated EP(1), EP(2), EP(3), and EP(4). Through these receptors, PGE(2) modulates renal hemodynamics and salt and water excretion. The intrarenal distribution and function of EP receptors have been partially characterized, and each receptor has a dist...

Prostaglandin (PG)E derivatives are widely used for treating gastric mucosal injury. PGE receptors are classified into four subtypes, EP(1), EP(2), EP(3), and EP(4). We have tested which EP receptor subtypes participate in gastric mucosal protection against ethanol-induced gastric mucosal injury and clarified the mechanisms of such protection. The gastric mucosa of anesthetized rats was perfuse...

A rapid, novel spectrofluorimetric method to determine epristeride (EP) in biological fluids and a pharmaceutical formulation was developed, based on the fact that fluorescence intensity of l-tryptophan could be quenched by EP in the medium of pH=9.0. The various factors influencing fluorescence quenching were discussed. The quenching mechanism was investigated with the quenching type, synchron...

This brief review analyzes the evolution of motor control theories along two lines that emphasize active (motor programs) and reactive (reflexes) features of voluntary movements. It suggests that the only contemporary hypothesis that integrates both approaches in a fruitful way is the equilibrium-point hypothesis. Physical, physiological, and behavioral foundations of the EP-hypothesis are cons...

Growth, body composition and energetic efficiency of early-pregnant (EP), normal-pregnant (NP) and virgin mice fed ad libitum were studied. Mean mating ages were 29.4 + .45 and 51.5 + .29 days for EP and NP females, respectively. Protein, fat and ash weights and caloric value at parturition were greater in NP than in EP females, as were the percentages of protein and fat. However, EP females ha...

Expressing and understanding one's own emotional responses to negative events, particularly those that challenge the attainment of important life goals, is thought to confer physiological benefit. Individual preferences and/or abilities in approaching emotions might condition the efficacy of interventions designed to encourage written emotional processing (EP). This study examines the physiolog...

Epidermal growth factor (EGF) family members, including epiregulin (EP), play a fundamental role in epithelial tissues; however, their roles in immune responses and the physiological role of EP remain to be elucidated. The skin has a versatile system of immune surveillance. Biologically active IL-1alpha is released to extracellular space upon damage from keratinocytes and is a major player in s...

The aim of this study was to compare how respiratory compensation point (RCP) and end-test power (EP) change in response to the same four-week high intensity interval training (HIIT). The power output associated with RCP and EP before and after HIIT were recorded in 24 recreationally active participants (14 men and 10 women). RCP was determined from an incremental exercise test and EP was deriv...

Enteropeptidase (EP) is a serine proteinase and activates trypsinogen to trypsin, thus playing an important role in food digestion. Nevertheless, the localization of EP is still controversial, likely due to a lack of studies using specific antibodies against EP. The aim of this study was to define cellular localization of EP in human duodenum and expression in tumor cells at the duodenal region...

We examine climate change impacts on net primary production (NPP) and export production (sinking particulate flux; EP) with simulations from nine Earth system models (ESMs) performed in the framework of the fifth phase of the Coupled Model Intercomparison Project (CMIP5). Global NPP and EP are reduced by the end of the century for the intense warming scenario of Representative Concentration Pat...
