Urbanization and economic development cause water pollution in the inner-city canals and rivers globally. Bung Xang canal in Can Tho city of Vietnam is facing problems with water pollution due to the lack of centralized wastewater treatment plants and low public awareness on environmental protection. Perception of local residents was collected using structured questionnaires including both qualitative and quantitative information.

Sensitivity of cholinesterase activity in juvenile giant freshwater prawn (Macrobrachium rosenbergii de Man, 1879) to organophosphate diazinon.

Pesticides containing diazinon are frequently used in agriculture in the Vietnamese Mekong delta region leading to their potential residual occurrence in the environment. Under laboratory conditions, exposure to diazinon has been shown to result in adverse inhibition of cholinesterase enzyme (ChE) activity and subsequent death in several fish species. This study investigated a 96-h median lethal concentration (LC50) of diazinon concentrations from 0.

Comparison of Novel, Bach Mai Boston Tool (BBT) and the Patient-Generated Subjective Global Assessment (PG-SGA) for Oncology Inpatients.

Oncology inpatients are at high risk of malnutrition. Identification of at risk patients by nutrition screening requires a practical and easy to use tool. The aim of this study was to determine the validity of the Bach Mai Boston Tool (BBT) compared to a 'gold standard' full nutrition assessment using the Patient-Generated Subjective Global Assessment (PG-SGA).

The combined effect of Bassa 50EC and Vitashield 40EC on the brain acetylcholinesterase activity in climbing perch (Anabas testudineus).

The combined effect of Vitashield 40EC (chlorpyrifos ethyl-CPF) and Bassa 50EC (fenobucarb-F) was compared with the effects from exposure to the two pesticides separately, by measuring the brain acetylcholinesterase (AChE) activity in climbing perch fingerlings (Anabas testudineus). The experiment was conducted under controlled laboratory conditions and included three treatments containing 0.173 mg/L of CPF, 1.

Evaluation of the joint toxicity of chlorpyrifos ethyl and fenobucarb on climbing perch (Anabas testudineus) from rice fields in the Mekong Delta, Vietnam.

Organophosphates (e.g. chlorpyrifos ethyl) and carbamates (e.
