Carbon monoxide (CO) is a colorless, odorless, and non-irritating gas produced as a result of incomplete combustion of carbon-containing fuels and materials. CO can affect all tissue organs including the brain, heart, kidney, skeletal muscle, skin, peripheral nerve, etc. (1). The clinical presentation of CO poisoning are variable and nonspecific. It is well-known about CO intoxication of brain ...

Pekka Sulkunen ABSTRACT Theoretical attempts to formulate cultural theories of drinking and drug use have traditionally stemmed from norm-theory or functionalism. These tend to reduce drinking and drug practices to intoxication alone or to neglect intoxication altogether.. The semiotic turn in the 1980s brought “meaning” to the focus of cultural studies. This article proposes, following Bruno L...

Cannabis use history as predictor of neurocognitive response to cannabis intoxication remains subject to scientific and policy debates. The present study assessed the influence of cannabis on neurocognition in cannabis users whose cannabis use history ranged from infrequent to daily use. Drug users (N = 122) received acute doses of cannabis (300 μg/kg THC), cocaine HCl (300 mg) and placebo. Coc...

abstract lettuce is one of the best accumulators of heavy metals and nitrate between leafy vegetables. through this research, it was tried to decreased cadmium absorption with humic acid (ha) and studies the effect of ha on the accumulation and metabolism of nitrate. plants were grown in the peat/perlite and irrigated with hoagland solution with addition of cadmium (2 and 4 mg l -1) and ha (100...

nitrate concentration of the soil, at the start of growing season, is high due to minerali-zation of soil organic n during the fall and the addition of n fertilizers. it may be useful to exploit this n form as much as possible. therefore, the nitrate uptake, assimilation and dry matter production of several wheat cultivars were examined in a series of experiments using a hydroponic culture syst...
