rodlet cells are frequently found in teleost fishes and although their role in organisms is not completely understood. the occurrence of these cells are related to stress and may undergo changes in contaminated environments, thereby allowing their use as biomarkers. this hypothesis is tested in the present study. thirty specimens of oreochromis niloticus were divided into three groups, two grou...

background: chlorpyrifos is an organophosphate pesticide that elicits broad-spectrum insecticidal activity against a number of important arthropod pests. determining the insecticides’ toxicity to amphibians can give us a better understanding regarding the role of toxicants in amphibian declines. this information would be beneficial to assess their ecological relevance at environmental concentra...

A pilot Integrated Fruit Production (IFP) programme for pest and disease management was evaluated on approximately 88 apple orchards throughout New Zealand. Insect control was based on increased use of biological control, monitoring and threshold-based applications of insecticides. The insect growth regulator tebufenozide was used for control of codling moth and leafrollers, while homopteran pe...

This paper discusses the toxicity and antidotal effects of 32 compounds. Screening studies have shown that these compounds combined with atropine are effective antidotes against the organophosphate nerve agents Tabun and/or Soman, having a therapeutic factor equal or greater than 2.0 when tested in mice or rats. We analysed the results of these studies, and recommend that these compounds should...

We have performed a quartz crystal microbalance (QCM) study of the uptake and nanotribology of organophosphate (tricresylphosphate (TCP) and t-butyl phenyl phosphate (TBPP)) layers adsorbed from the vapor phase onto amorphous and polycrystalline silicon and octadecyltrichlorosilane (OTS) treated silicon substrates. The materials were selected for their relevance to MEMS applications. About 3–5 ...

A case of organophosphate (OP) poisoning who recovered after requiring almost 1000 mg of atropine, 10 gm of PAM and ventilatory support for 7 days is presented here. The overview of organophosphate poisoning and its management is given. With the approach adopted, the mortality reported in the general medicine unit in the central hospital in Nepal is 7.4%. The two important aspects of the manage...

Background: Organophosphate pesticide (OP) exposure may be associated with the subsequent development of cognitive decline, which is used to assess early stage Alzheimer’s disease. We investigated correlations between biomarkers OP and decline among farmers nonfarmers.

Prolonged exposure to organophosphates in low concentrations caused diarrhoea in 38 students, lecturers and other personnel at an agricultural college. The symptoms of those affected, plasma pseudocholinesterase levels, topography of the orchards and vegetable gardens, the various insecticides and quantities used, and the exposure due to prevailing winds have been studied. We conclude that safe...
