Nowadays, hydrogels are widely used as wound dressings in biomedical applications. Similar to other types of the moist (wet) wound dressings, it is necessary to have sufficient information about their dehydration kinetics during the pre-usage period (e.g. storage duration) and also the wound healing process. In this work, hydrogel wound dressings based on polyvinyl alcohol were prepared by...

We have known for many years that the dehydration of plant cells can lead to accumulation of the plant growth regulator ABA. Application of this compound to well-watered plants mimics many of the effects of soil drymg on gene expression, physiology, growth, and development, making this compound a strong candidate for a role in the droughted plant. Dehydration of leaves can result in massive acc...

abstract cerebral sinovenous thrombosis (csvt) in children has rarely been reported in the literature, especially without underlying disorder. it has increasingly been diagnosed due to clinical awareness and sensitive neuroimaging techniques. the aim of this article was to report a case of cerebral sinovenous thrombosis without underlying disorder. we reported a 5 year old girl, presented with ...

during the recent decades, substantial changes are made in the borders and contents of physiology as a basic course for the students in medicine. here some strategies are presented to preserve the classical and integrative approaches in teaching physiology, while these approaches extent our knowledge to molecular, sub-cellular and cellular levels.

BACKGROUND An accurate assessment of the degree of dehydration in infants and children is important for proper decision-making and treatment. This emphasizes the need for laboratory tests to improve the accuracy of clinical assessment of dehydration. The aim of this study was to assess the relationship between clinical and laboratory parameters in the assessment of dehydration. METHODS We eva...

there is no doubt that breast-feeding is the best and safest way of feeding infants. physiological weight loss occurs in the first two or three days of life, and the achievement of birth weight is expected towards the end of the first week. hypernatremic dehydration may occur in exclusively breast-fed infants if milk supply is low during these first few days. it is not because of the high sodiu...

Larvae of the Antarctic midge, Belgica antarctica, routinely face periods of limited water availability in their natural environments on the Antarctic Peninsula. As a result, B. antarctica is one of the most dehydration-tolerant insects studied, surviving up to 70% loss of its body water. While previous studies have characterized the physiological effects of a single bout of dehydration, in nat...
