BACKGROUND Microvascular perfusion changes in scalds in children during the first weeks after injury is related to the outcome of healing, and measurements of perfusion, based on laser Doppler imaging, have been used successfully to predict the need for excision and grafting. However, the day-to-day changes in perfusion during the first weeks after injury have not to our knowledge been studied ...

Seeds of Silybum marianum which have been used to treat liver diseases have an active component called silymarin. Hairy root cultures of S. marianum could be able to produce silymarin. There is evidence that the use of elicitors has been an important strategy for improving the production of secondary metabolites. Elicitation is an interesting topic to investigate cell signaling pathway in secon...

OBJECTIVES To evaluate the effect of three calcium sodium phosphosilicate (CSPS)/sodium monofluorophosphate containing dentifrices, compared to positive and negative controls on plaque re-growth in a non-brushing model, after 4 days of twice daily use, as determined by plaque area and Turesky plaque index (TPI). METHODS This was an exploratory, single-centre, examiner-blind, randomised, contr...

BACKGROUND Evidence suggests that sleep loss is associated with an increased risk of obesity and diabetes; however, animal models have failed to produce weight gain under sleep deprivation (SD). Previous studies have suggested that this discrepancy could be due to more extreme SD conditions in experimental animals, their higher resting metabolic rate than that of humans, and the decreased oppor...

chlorpyrifos is one of the organophosphate pesticides that are commonly used to control insects in domestic activities and many agricultural farms that are located in close to water sources. hence, the present study, investigate the lethal toxicity of this pesticide. in this study, fish were treated in groups of 21 with different concentrations of chlorpyrifos (aria brand with active ingredient...

Bioassays are a useful tool for detecting possible impacts of pollutants on biota. Hyalella curvispina is an epibenthic amphipod native to South America used evaluate the toxicity environmental samples. However, information gaps persist regarding their sensitivity certain and tolerance salinity, so this research provides new data characterize response. In work, copper phenanthrene was analyzed,...

background: the human leukocyte antigen (hla) matching between organ donor and recipient is an acceptable strategy in clinical transplantation since 1964. however, in bone marrow transplantation, finding matched donors is often problematic. thus new method for down regulation of hla can be an alternative strategy to solve this problem. objective: to examine the effect of serum starvation on hla...

background: since heavy metals can accumulate in the tissues of aquatic organisms, they can cause a range of hazardous effects which can become harmful to humans. the aim of this study was to investigate the acute effects of some heavy metals as potential dangerous substances by assessing the mortality effects of mercuric chloride (hgcl2), lead chloride (pbcl2) and zinc sulfate (znso4) pollutan...

acute toxicity (96h-lc50) of potassium permanganate (pm) was determined for caspian kutum rutilus frisii kutum at two size classes (1 and 3 g). static renewal method was used. fish were exposed to different concentrations of pm and mortality was recorded thereafter, until 96 h. exposed fish showed behavioral stress indicators. 96h-lc50 was calculated to be 3.204 (3.147-3.260) mg/l for small fis...

ABSTRACT Casein precipitated by carbon dioxide (CO2-casein), and commercial sodium and calcium caseinates (1% w/v in water) were thermally deamidated at pH 8 for up to 96h at 85, 100, and 1158C. CO2-cas...
