Nanotechnology permits broad advances in agriculture. However, as it is still at a relatively early stage of development, the potential risks remain unclear. Herein, for the first time, we reveal the following: 1) the impact of multi-walled carbon nanotubes (MWCNTs) on the accumulation/depuration behaviors of contaminants in crop, mustard (Brassica juncea), and 2) the permeability and transport...

objective: the toxic effects of sublethal concentrations of endosulfan on oreochromis niloticus was examined using bioaccumulation and histopathology studies of the liver as toxicological endpoint.  methods: the organization for economic cooperation and development #407 recommended static renewal bioassay was employed during the test .the test fish were exposed to sub-lethal concentrations sepa...

INTRODUCTION The use of extrarenal depuration techniques is increasingly frequent in patients admitted to the ICU. The use of these procedures has been related to a decrease in plasma concentrations of several antimicrobials, among which fluconazole. The activity of antifungal agents depends on achievement on adequate concentrations in plasma and at the site of infection. Micafungin is a new an...

The present study investigated both the effects of cadmium on the social interactions of rainbow trout and the differential accumulation of waterborne cadmium among social ranks of fish. Fish exposed to waterborne cadmium concentrations of 2 microg l(-1) for 24 h, followed by a 1, 2 or 3 day depuration period in clean water, had a decreased ability to compete with non-exposed fish. However, the...

A simple method for analyzing masses of water suspended fullerenes (nC60) in Daphnia magna by extracting to toluene and measuring by ultraviolet-vis spectrophotometry was developed. This method was used to assess bioaccumulation and depuration rates by daphnia after nC60 exposure in artificial freshwater. Accumulation was rapid during the first few hours, and based on accumulation modeling, 90%...

A quantitative structure-activity relationship (QSAR) model on depuration rate constants (k(d)) of polychlorinated biphenyls (PCBs) in freshwater mussel Elliptio complanata was successfully constructed using electrotopological state indices (ESI) and partial least squares (PLS) regression. The cross validated Q2(cum) and the correlation coefficient R for the model were determined to be 0.845 an...

In this study, autometallography and immunohistochemistry were used to localize and quantify cadmium and metallothionein (MT) levels, respectively, in cellular compartments of turbot liver on exposure to cadmium for 7 days and further depuration treatment for 14 days. Metals weakly bound to proteins (i.e. MTs) in hepatocyte lysosomes were visualized as black silver deposits (BSDs) using a light...

Sauna therapy has been used for hundreds of years in the Scandinavian region as a standard health activity. Studies document the effectiveness of sauna therapy for persons with hypertension, congestive heart failure, and for post-myocardial infarction care. Some individuals with chronic obstructive pulmonary disease (COPD), chronic fatigue, chronic pain, or addictions also find benefit. Existin...
