Behavioral observation used to estimate pesticide exposure for farm workers in Brazil
(Pontificia Universidade Católica do Rio de JaneiroUniversidade de BrasíliaUniversidade de São Paulo, 2009)
Assessment of the harm caused by exposure to pesticides requires that a measure of exposure be available. While such information is available without difficulty in controlled laboratory studies, estimating the exposure of ...
Summer exposure assessment of Cu and Zn in drinking water in Shanghai, China
(TAYLOR & FRANCIS INC, 2006)
Daily exposures to chemicals in drinking water are of importance in risk assessment to human health. However, exposure assessment of chemicals in drinking water has seldom been performed in China. Until now, no such a ...
Influence of Time and Frequency of Passive Smoking Exposure on Mucociliary Clearance and the Autonomic Nervous System
(Daedalus Enterprises Inc, 2016-04-01)
BACKGROUND: There are still gaps in the knowledge regarding the damage to mucociliary and autonomous systems from passive exposure to cigarette smoke. Also, the influence of the frequency and duration of exposure on these ...
Does occupational exposure to anesthetic gases lead to increase of pro-inflammatory cytokines?
(Inflammation Research : Official Journal Of The European Histamine Research Society ... [et Al.], 2015)
There is great concern about the possible harmful effects of exposure to volatile anesthetics. The current study aimed at evaluating, for the first time, the effects of occupational exposure to anesthetic gases on physicians ...
Balance between early life tolerance and sensitization in allergy: dependence on the timing and intensity of prenatal and postnatal allergen exposure of the mother
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
P>Allergens can be maternally transferred to the fetus or neonate, though it is uncertain how this initial allergen exposure may impact the development of allergy responses. To evaluate the roles of timing and level of ...
Novel monitor paradigm for real-time exposure assessment
(Nature Publishing Group, 2010-06)
A wearable monitor that can reliably, accurately, and continuously measure personal exposure levels of various toxicants would not only accelerate the current environmental and occupational health and safety studies, but ...
The effects of exposure time on the surface microhardness of three dual-cured dental resin cements
(2011-09-01)
This study evaluated the exposure time of light-curing of the polymers used for cementation on microhardness test in different storage times. The polymers (specifically called resin cements) were RelyX ARC, RelyX U100, and ...
Effects of light exposure time on composite resin hardness after root reinforcement using translucent fibre post
(ELSEVIER SCI LTD, 2008)
Objectives: The purpose of this in vitro study was to evaluate the Vickers hardness (VHN) of a Light Core (Bisco) composite resin after root reinforcement, according to the light exposure time, region of intracanal ...
