Effects of chlorpyrifos toxicity on brain, pseudobranchial neurosecretory system and swimming performance of a catfish, .

In the present study, it was aimed to evaluate the adverse effects of CPF on the histopathology of the optic tectum and cerebellum, pseudobranchial neurosecretory system (PNS), biochemical assays of brain tissue, and locomotory behavior in catfish, . The fishes were exposed to an environmentally relevant concentration of 0.09 and 0.

Implementation of advanced radiotherapy technology to improve clinical outcomes in rural NSW.

Problem: Availability of advanced radiotherapy technology to treat cancer is limited in regional Australia. At Central West Cancer Care Centre, the utilisation rate of intensity-modulated radiotherapy and volumetric modulated arc therapy was significantly lower compared to other NSW public health services. Stereotactic ablative body radiotherapy treatment was not available at Central West Cancer Care Centre.

Acute toxic effects of chlorpyrifos on pseudobranchial neurosecretory system, brain regions and locomotory behavior of an air-breathing catfish, (Bloch 1794).

In the late twentieth century, tremendous use of second-class organophosphate insecticides especially chlorpyrifos (CPF) resulting into heavy accumulation in different non-targeted aquatic species including fishes leads to apparent structural and biochemical changes in different organs and related abnormal behavioral responses. The present study has been undertaken as a pioneer attempt to assess the toxic effects of CPF on histopathological changes in pseudobranchial neurosecretory cells (PNSCs) of a neuroendocrine system of gill region, optic tectum (OT) and cerebellum, biochemical changes (acetylcholinesterase (AChE) activity and antioxidant markers) in the brain and associated locomotory behavioral alterations in air-breathing catfish, . The fishes were exposed to CPF concentration of 1.
