communication disorder is a widespread disabling problems and associated with adverse, long term outcome that impact on individuals, families and academic achievement of children in the school years and affect vocational choices later in adulthood. the aim of this study was to determine prevalence of speech disorders specifically stuttering, voice, and speech-sound disorders in primary school s...

The process of haemostasis is complex and is further complicated in the parturient because of the physiological changes of pregnancy. Understanding these changes and the impact that they have on the safety profile of the anaesthetic options for labour and delivery is crucial to any anaesthetist caring for the parturient. This article analyses current theories on coagulation and reviews the phys...

CONTEXT The liver as an important organ in the body has many essential functions in physiological processes. One of the major activities of liver is drug metabolism. Hepatic dysfunction affecting hepatic physiological activities, especially drug metabolism can cause many problems during anesthesia and administration of different drugs to patients. EVIDENCE ACQUISITION Studies on hepatic disor...

Few therapies exist for the relief of dyspnea in restrictive lung disorders. Accumulating evidence suggests that nebulized opioids selective for the mu-receptor subtype may relieve dyspnea by modulating intrapulmonary opioid receptor activity. Our respective primary and secondary objectives were to test the hypothesis that nebulized fentanyl (a mu-opioid receptor agonist) relieves dyspnea durin...

Fibre is an essential component of the human diet that crucial for health, physiological and functional effects dietary fibre are associated with a wide range short-term long-term health benefits. provides energy source gut microbiome. The fermentation by microbiome results in production variety compounds benefits extend beyond gut, to immune system organs such as liver, kidneys even brain. inc...

Cognitive disorders can be associated with brain trauma, neurodegenerative disease or as a part of physiological aging. Aging in humans is generally associated with deterioration of cognitive performance and, in particular, learning and memory. Different therapeutic approaches are available to treat cognitive impairment during physiological aging and neurodegenerative or psychiatric disorders. ...

Many physiological processes and most endocrine functions show fluctuations over the course of the day. These so-called circadian rhythms are governed by an endogenous network of cellular clocks and serve as an adaptation to daily and, thus, predictable changes in the organism's environment. Circadian clocks have been described in several tissues of the stress axis and in adipose cells where th...

The recurring light/dark cycle that has a period length of about 24 hours has been internalized in various organisms in the form of a circadian clock. This clock allows a precise orchestration of biochemical and physiological processes in the body thus improving performance. Recently, we found that the clock component PERIOD2 (PER2) can coordinate transcriptional regulation of metabolic, physio...

The health of physiological tissue is governed by the continuous conversion of mechanical stimulus (stress) to bio-chemical response, a concept known as mechanical homeostasis. If this regulatory imperative becomes flawed, it may be detrimental, and consequently invoke or encourage the progression of various musculoskeletal disorders. This notion is corroborated by the quantification of altered...

This paper reviews biofeedback research from the perspective of cybernetic/feedback theory and applies the theory to the behavioral treatment of psychosomatic disorders. The concept of disregulation is used to elucidate how environmental factors can modulate the central nervous system and effect homeostatic, self-regulatory control of peripheral organs. When feedback from peripheral organs is d...
