Background: Underlying diseases and aggressive procedures, such as different types of surgery and care, for patients with critical conditions in intensive care units (ICU) may be associated with physiological disorders. Objectives: This study intended to determine the effect of therapeutic touch on physiological variables of patients undergoing mechanical ventilation in ICU. Methods: This...

objective: addiction, especially morphine dependence is a prevalence and incurable disease. with regard to low ability of new chemical drugs in treatment of addicted ones and with respect to herbal medicine recommendation due to lower side effects and cheap production. this study experimentally examined the effect of p.harmala on morphine withdrawal syndrome. materials and methods: animals wer...

Thyroid hormone production is regulated via pituitary thyrotropin (TSH) modulation of thyroxine (T4) prohormone secretion by the thyroid gland and regulation of active triiodothyronine (T3) production in peripheral tissues via metabolic events influencing activities of the iodothyronine monodeiodinase enzyme systems. Control at both levels is developmentally regulated and modified in serious no...

Hunger and satiety are usually discussed from the perspective of the central nervous system. In this paper we instead find the foundation for an understanding of hunger in the basic biochemical and physiological processes of energy metabolism. Such considerations suggest that the stimulus for hunger should be sought among changes that occur in the supply of metabolic fuels rather than in the ut...

The aim of this article is to review those aspects of corrosion behaviour that are most relevant to the clinical application of implant alloys. The special modes of corrosion encountered by implant alloys are presented. The resistance of the different materials against the most typical corrosion modes (pitting corrosion, crevice corrosion and fretting corrosion) is compared, together with obser...

Phalaenopsis is an important genus of orchids that is grown for economical production of cut flower and potted plants. The objective of this study is the evaluation of correlation between morphological and physiological traits of self and cross-pollination of 5 varieties of Phalaenopsis orchid. Some morphological traits were measured: Capsule length (CL), capsule volume (CV), weight of seeds in...

Introduction: Sleep deprivation is one of the factors affecting the physiological performance of athletes and laboratory evidence has suggested a link between sleep deprivation and decreased physical performance of athletes. The aim of this study was to determine the effect of sleep deprivation on objective and subjective physiological responses of student-athletes. Material and Methods: The r...
