public how to protect against 03. People whose 03 sensitivity is clinically apparent by symptoms or lung function loss are commonly advised to minimize exposure by avoiding outdoor exercise during pollution episodes. The same advice now seems appropriate for clinically "insensitive" individuals, given that they may experience asymptomatic lung function decrements, as well as lung inflammation a...

Fourth-year medical students at Zagreb University School of Medicine were surveyed about their knowledge and attitudes regarding HIV/AIDS in 2002/03 and this was compared to a student generation studying during 1993/94. Results indicated that the 2002/03 students scored significantly higher then did 1993/94 students on knowledge, and attitudes towards HIV/AIDS. However, 84% of 2002/03 students ...

The main objective of the present investigation is to evaluate the anti-inflammatory & analgesic activity of ethanolic extract of Shirishadi polyherbal compound on rats. Shirishadi compound consist of three herbal drugs namelyShirisha (Albizzia lebbeck), Nagarmotha (Cyprus rotandus) & Kantakari (Solanum xanthocarpum).In Ayurveda (ancient Indian system of medicine) all these herbs alone or in co...

Ethylenediurea (EDU), N[2-(2-oxo-l-imidazolidinyl) ethyl]-N'-phenylurea is known to prevent ozone (03) damage to leaf tissues. However, the mechanisms of protection are unclear. We tested the hypothesis that EDU protects against 03 damage by scavenging hydroxyl free radicals (OH). An in vitro study involving the use of high-performance liquid chromatography equipped with an electrochemical dete...

The aim was to assess heterosis in a set of 16 summer-squash hybrids, and evaluate the combining capacity of the respective parental lines, which differed as to the degree of parthenocarpy and resistance to PRSV-W (Papaya Ringspot Virus-Watermelon strain). The hybrids were obtained using a partial diallel cross design (4 × 4). The lines of parental group I were 1 = ABX-037G-77-03-05-01-01-bulk,...

This article reports the development and evaluation of two nano-emulsions (F45T-03/HFB and F15T-03/PFOB) containing fluorinated trityl radicals dissolved in perfluorocarbons. Preparation with a high-pressure homogenizer conferred sub-micronic size to both nano-emulsions. In vitro and in vivo EPR spectroscopy showed that the nano-emulsions had much greater oxygen sensitivity than the hydrophilic...

We screened a small molecular library that was designed and independently synthesized in vitro and found a new drug (MY-03-01) that is active against ovarian cancer. We established that MY-03-01 effectively inhibited SKOV-3 cell survival in a dose-dependent manner, based on cell viability rates, and that it not only induced SKOV-3 apoptosis by itself, but also did so synergistically with paclit...

A global three-dimensional model of tropospheric hemistry is used to investigate the changes in tropospheric 03 and OH since preindustrial times as a result of fuel combustion and industry, biomass burning, and growth in atmospheric CH 4. Model results indicate a 63% increase of the global tropospheric 03 burden from preindustrial times to present (80% and 50% in the northern and southern hemis...
