Mercuric chloride was introduced per Os in albino rats (Rattus norvegicus) as the LD50 (9.26 mg/kg b.w.). The assessment of mercuric toxicity done both after acute (0.926 b.w.) and sub-acute (0.033 treatment, while Panax ginseng also (10 separately. treatment significantly increases mercury retention liver blood serum along with increase weight, alone caused significant decrease weight blood. I...

Anthropogenic activities and the demand for trace elements have risen, causing an increase in their environmental levels, which could affect biota. High levels of living beings been associated with toxicity, metabolic disorders, oxidative stress, cancer. Seabirds, such as gulls, used bioindicators pollution caused by anthropogenic sources. Gulls are widely distributed worldwide, usually occupyi...

Selenium (Se) supplementation in the nutritionally relevant range counteracts methylmercury (MeHg) toxicity. Since Se tends to be abundant in fish, MeHg exposures alone may not provide an accurate index of risk from fish consumption. Molar ratios of MeHg:Se in the diets and Hg:Se in tissues of exposed individuals may provide a more accurate index. This experiment compared MeHg toxicity in relat...

BACKGROUND AND PURPOSE Posterior reversible encephalopathy syndrome (PRES) is known to occur after solid organ transplantation (SOT), potentially associated with cyclosporine and tacrolimus. In this study, we assess the frequency and clinical and imaging characteristics of PRES after SOT. MATERIALS AND METHODS We identified 27 patients (13 men and 14 women; age range, 22-72 years) who develop...

In the present study, Mercury (Hg) accumulation in different tissues of Yellowfin seabream under different Hg concentrations in the medium were investigated. For this, PurPuse 45 fish specimen of the same size (19.2±1.8cm and 134.0±36.1 g) were caught from Musa Estuary, in northwest of the Persian Gulf and transferred to the laboratory. Fish were divided into five different groups of 9 fish ...

The toxicity of arsenic and mercury is highly dependent on their unique chemical forms, mobility, bioavailability, biological roles. This places a strong demand specific metal species analysis rather than total quantification. Graphene oxide (GO) an excellent adsorbent for the extraction ions; however, functional moieties GO surface are not ion-specific. In this work, we chemically introduced t...

Solid waste management constitutes a major concern and unresolved problem in most parts of the world, particularly developing countries where solid is disposed unregulated dumpsites public spaces. This practice can lead to contamination environmental compartments such as soil, surface groundwater which could negatively impact human health. In this study, soil samples were collected from 15 sele...

Spatial trends and comparative changes in time of selected trace elements were studied in liver tissue from polar bears from ten different subpopulation locations in Alaska, Canadian Arctic and East Greenland. For nine of the trace elements (As, Cd, Cu, Hg, Mn, Pb, Rb, Se and Zn) spatial trends were investigated in 136 specimens sampled during 2005-2008 from bears from these ten subpopulations....

Insulin-like growth factor-I (IGF-1) ameliorates cardiac dysfunction in diabetes although the mechanism of action remains poorly understood. This study examined the role of PI-3 kinase/Akt/mammalian target of rapamycin (mTOR) and calcineurin pathways in cardiac effects of IGF-1 against glucose toxicity. Adult rat ventricular myocytes were cultured for 8 h with either normal (NG, 5.5 mM) or high...

Heavy metals (HMs) have the characteristics of high toxicity, long residual time, and difficult degradation, which pose a potential threat to aquatic ecosystems. The distribution migration HMs in different media can reflect their impact on ecosystem health. In this study, we analyzed seven (Zn, Cu, Cr, Ni, Hg, As, Pb) water sediment five groups organisms (fish, Crustacean, cephalopod, bivalvia,...
