1. Oxygen in concentrations of over 70 per cent of an atmosphere is poisonous to dogs, rabbits, guinea pigs and mice. 2. The poisonous effects manifest themselves in drowsiness, anorexia, loss of weight, increasing dyspnea, cyanosis and death from oxygen want. 3. The cause of oxygen want is a destructive lesion of the lungs. 4. The lesion may be characterized grossly as an hemorrhagic edema. Mi...

AIM To report our experience of acute kidney injury (AKI) developed after exposure to poisonous substance. METHODS Retrospective study where data was collected from case records of patients coming to this institute during January 1990 to May 2016. This institution is a tertiary care center for renal care in the metropolitan city of Karachi, Pakistan. History of ingested substance, symptoms on...

From the poisonous mushroom Clitocybe acromelalga, a new glutamate-containing dipeptide was isolated. Its structure was deduced to be N-(gamma-aminobutyryl)-L-glutamic acid (10) based on spectral data and was confirmed by synthesis.

If an animal experiences gastrointestinal malaise after eating a novel feed, it develops a dislike for the feed called a conditioned flavor aversion (CFA). Understanding flavor aversions is important for diet-training procedures, understanding animal responses to poisonous plants, and preparing animals for new foraging environments. Our research objectives were to determine how variation in 1) ...

Theories of species coexistence have played a central role in ecology and evolutionary studies of the origin and maintenance of biodiversity in highly diverse communities. The concept of niche and associated theories predict that competition for available ecological space leads to a ceiling in species richness that influences further diversification patterns. By contrast, the neutral theory sup...

Morphological integration can respond to environmental conditions, a response that may be dynamic through ontogeny. Among fishes, brook charrs (Salvelinus fontinalis) display a trophic polymorphism that makes it a good species for analyzing the ontogeny of morphological integration. To better understand the processes regulating variation and integration, we assess the ontogenetic dynamics of co...

The study was designed to investigate the effect of duration of frozen storage on the proximate profile of fishes lizadussmieri, sparidae, sciaenide and platycephalidae. The fishes were subjected to sixty days of frozen storage. Protein decreases with increasing duration of frozen storage; with the fresh samples (not frozen) having the highest protein content (13.02 ± 0.09%). while the least (1...

Environmental factors play a major part in human health. Environmental pollutants are often as poisonous to humans as the environment. Presently, much time and energy is dedicated to keeping pollution apart from human society, with varying success. But as global population densities rise, current levels of pollution will become inviable due to public health concerns. An emergent example of this...
