Introduction of personal protective equipment (PPE) in the process of quantitative exposure and risk assessment should be addressed carefully. PPE which have been designed and manufactured according to CE-criteria and have proved to pass relevant test criteria, can be classified as "proper functioning". However, test criteria for PPE are not equal to levels of protection which can be achieved i...

the prevalence of primary infection with t. gondii in pregnant women and risk of congenital infection in their neonates in various parts of tehran are unknown. the prevalence rate of antibodies to t. gondii ranges from 24% in tehran to 62.7% in babol. this study describes the epidemiology of toxoplasma infection in pregnant women in tehran and risk factors of congenital toxoplasmosis in newborn...

OBJECTIVES a) To identify possible risk factors associated with rural accidents in women, b) to describe women's knowledge about zoonosis, c) to describe women's risk perception about farming, d) to describe mothers' risk perception about children's activities in rural settings, e) to estimate the initial age of exposure to the rural setting and its dangers, and f) to identify possible risk fac...

AIM To determine the use of personal protective equipment (PPE) among pregnant greenhouse workers in Italy and to identify risk factors related to the non-use of appropriate preventive measures. METHODS A structured questionnaire was administered by trained interviewers, to Italian female greenhouse workers regarding their use of PPE and the occurrence of adverse pregnancy outcomes in their f...

objective: barberry root extract contains various alkaloids that are considered as antioxidants. beneficial effect of aqueous extract of berberis integerrima root (aebir) was evaluated for renal function in diabetic rats induced by stz. material and methods: diabetes was induced by i.p. injection of streptozotocin (65 mg/kg bw) to rats, after 15 h of fasting. diabetic rats were randomly grouped...

background: dna immunization with plasmid dna encoding bacterial, viral, parasitic and tumor antigens has been reported to trigger protective immunity. objective: to evaluate the use of a dna immunization strategy for protection against anthrax, a plasmid was constructed. methods: the partialsequence of protective antigen of bacillus anthracis, amino acids 175-764, as a potent immunogenic targe...

Pili are essential virulence factors in many Gram-negative bacteria; however, they have not been described in most important Gram-positive pathogens. While screening the sequence of multiple genomes of Group B Streptococcus, we identified protective antigens that formed high molecular weight polymers. Immunogold electron microscopy revealed that the structures have a pilus-like form. These larg...

The interferon response protects cells from invading viral pathogens by transcriptionally inducing the expression of interferon-stimulated genes (ISGs), some of which encode effectors with varied antiviral functions. As screening technologies improve and mouse model development quickens, more ISGs are continually being identified, characterized mechanistically, and evaluated for protective role...
