OBJECTIVE An analysis of Canadian survey data was performed to identify independent predictors of different protective behaviours and of their use in combination. METHODS Data from light-skinned respondents of the 1996 National Survey on Sun Exposure & Protective Behaviours who spent 30+ minutes per day of their leisure time in the sun (N = 1,027) were analyzed. Multivariable logistic regress...

in this study silver/poly vinyl alcohol (pva) and silver/poly vinyl pyrrolidone (pvp) nanocomposites were prepared via reduction of silver salt by employing dmf (n, n`- dimethyl formamide) as a reducing agent. effects of protective agents such as pva and pvp were also described here. we show that the acidic ph of pvp solution also affects the interaction between protective agents and silver nan...

Human neonates are born with an immature and naı̈ve acquired immune system, and many of the innate components of mucosal immunity are not fully developed. Thus, the innate immune system of human milk is an important complement to the mucosal barrier of the developing gut. The nursing mother provides her infant many protective agents through milk, a growing number of which have been identified as...

Doxorubicin, used in pediatric chemotherapy regimens, has cardiotoxic effects. Dexrazoxane is co-administrated with doxorubicin to prevent its cardiotoxicity. Here we have explored some alternative food or drugs to be used in absence of dexrazoxane since it’s not readily available in Iran at this time. Keywords: Pediatric, chemotherapy, doxorubicin, cardiotoxicity, dexrazoxane, Iran.

Childhood sun exposure is a particularly important determinant of skin cancer, yet little data are available for children. This paper describes sun behaviour among Canadian children for the summer of 2006. As part of the Second National Sun Survey (NSS2), 1,437 parents reported on the time spent in the sun, and the frequency of sun protection behaviours and sunburning for one of their children ...

Novel stable tellurium-containing carbohydrate derivatives are prepared from hexitols and pentitols through a double nucleophilic substitution with NaHTe in PEG-400. These tellurosugars react at very high rates with two-electron oxidants, including hypochlorous and peroxynitrous acid, formed at sites of inflammation, and show considerable promise as protective agents against oxidative damage.

Personal protective equipment (PPE) is an important part of worker protection during filovirus outbreaks. The need to protect against a highly virulent fluid-borne pathogen in the tropical environment imposes a heat stress on the wearer that is itself a safety risk. No evidence supports the choice of PPE employed in recent outbreaks, and standard testing procedures employed by the protective ga...
