Fire-fighters’ personal protective clothing is the only source of protection for fire-fighters during fire-fighting. The protective clothing should provide adequate protection as well as should be comfortable to wear. The protection and comfort requirements are always the contradicting fact in several protective clothing including fire-fighters’. Appropriate material selection, clothing design ...

the aim of present study was to investigate the potential antioxidant and lung protective activities of sambucus ebulus (se) against toxicity induced by gamma irradiation. hydro alcoholic extract of se (20, 50 and 100 mg/kg ) was studied for its lung protective activity. . phenol and flavonoid contents of se were determined. male c57 mice were divided into 10 groups with five mice per group. on...

the aim of our work was to compare cytotoxic and membrane-damaging effects of o. majorana l. essential oil and linalool on hep g2 and to investigate their possible protective (antioxidant) effects against h2o2 induced membrane damage. the oils were investigated by gc and gc-ms and antioxidant activity was evaluated by dpph and -carotene–linoleic acid assays. assessment of cell viability was ma...

lead is an ubiquitous environmental toxin that induces a broad range of physiological biochemical, and behavioral dysfunctions. in this study, we examined the pathologic effects of lead acetate in nmri mouse ovarian tissue and the protective role of antioxidant l-cysteine, against the induced damage. we used lead acetate at a dose of 10 mg/kg, and l-cysteine at a dose of 200 mg/kg. both drugs w...

conclusions this study shows lower anti-hbs among students who were vaccinated at infancy compared to those vaccinated at older childhood or adolescence. also, subsequent measurement of anti-hbs level at the time of entrance to university is recommended for all previously immunized students. results vaccination coverage rates were 74.1%. about half the participants didn’t show serological evide...

We evaluated a personal protective equipment removal protocol designed to minimize wearer contamination with pathogens. Following this protocol often resulted in virus transfer to hands and clothing. An altered protocol or other measures are needed to prevent healthcare worker contamination.

Heat and mechanical protection properties of 6 fabric combinations commonly used in firefighters' protective clothing were assessed before and after different heat treatment. It was shown that after heat exposure, the values obtained were generally lower than in the original state. The mechanical properties of the materials were more affected by heat than by heat protective properties. In 2 cas...

We examined whether risk and protective factors of different functional trajectories were the same in 1,765 Dutch older persons. We assessed disability in 1993 and reassessed it in 2001. For 2001 as compared with 1993, we distinguished three trajectory groups: substantially poorer, somewhat poorer, and no change or better functioning. We assessed sociodemographic, health, and psychosocial poten...

Because few prospective studies have examined the independent influence of mothers and fathers on smoking experimentation, we tested the association between a set of parent-specific, familial and peer interactions with smoking experimentation in early adolescence. Data come from two cohorts in the British Youth Panel Survey (N = 1736; mean age at baseline, 11.26; SD = 0.65), a study of children...
