Sixteen healthy exercise trained participants underwent the following three, 10-h exposures in a randomized manner: (1) Hypobaric hypoxia (HH; 3450m terrestrial altitude) (2) Normobaric hypoxia (NH; 3450m simulated altitude) and (3) Normobaric normoxia (NN). Plasma oxidative stress (malondialdehyde, MDA; advanced oxidation protein products, AOPP) and(More)
Use of antiseptics and disinfectants is essential in infection control practices in hospital and other healthcare settings. In this study, the in vitro activity of a new promising compound, para-guanidinoethylcalix[4]arene (Cx1), has been evaluated in comparison with hexamidine (HX) and chlorhexidine (CHX), two older cationic antiseptics. The MICs for 69(More)
A review of clinical and experimental data pertaining to the standardization of allergenic extracts is presented. Various problems facing practicing allergists are outlined: potency and stability of extracts the reactivity of the patient, in vitro and in vivo methods for assessing potency. Practical recommendations for allergists concerning allergenic(More)
Independently, both inactivity and hypoxia augment oxidative stress. This study, part of the FemHab project, investigated the combined effects of bed rest-induced unloading and hypoxic exposure on oxidative stress and antioxidant status. Healthy, eumenorrheic women were randomly assigned to the following three 10-day experimental interventions: normoxic bed(More)
A selective review of clinical and experimental data pertaining to air pollution and its effects on health and disease is presented. Various air pollutants, their effects on health and national air quality standard levels are outlined. The guidelines for asthmatic patients to follow during air pollution episodes are enumerated.
