The relationship between amyloid and toxic species is a central problem since the discovery of amyloid structures in different diseases. Despite intensive efforts in the field, the deleterious species remains unknown at the molecular level. This may reflect the lack of any structure-toxicity study based on a genetic approach. Here we show that a structure-toxicity study without any biochemical ...
conclusions results from the present study elucidated that treatment with the aqueous extract of l. citriodora leaves was well tolerated via daily ip injection at doses up to 200 mg/kg for a period of 21 days and did not produce any toxicity. the safety of l. citriodora aqueous extract was also confirmed by cell viability assay. objectives the present study evaluated the acute, subacute, and ce...
In recent years, with the aggravation of environmental pollution, study aquatic ecotoxicology has become a hot topic. Some organisms, such as large fleas, toads, and zebrafish, have been developed applied model organisms. They increasingly used to bioaccumulation toxicity pollutants due advantages their small size, easy reproduction, short life cycle, low maintenance cost, ability combine genet...
Increased production and use of nanomaterials has led to an ever growing exposure of livingorganisms to these substances. Limited knowledge about possible toxicity of nanomaterialsand their potential to harm living creatures is becoming a serious concern. To address thisproblem, there is a need for development of diagnostic methods enabling effective determinationof potential toxicity of nanoma...
Despite intensive studies on examining the toxicity of nanomaterials (NMs), our current understanding on potential toxicity in relation to size and cellular responses has remained limited. In this work, we have developed a whole-cell based capacitive biosensor (WCB) to determine the biological toxicity of nanoparticles (NPs) using iron oxide (Fe3O4) NPs as models. This WCB chip comprised of an ...
rifampin, an antibiotic widely used for the treatment of mycobacterial infections, produceshepatic, renal and bone marrow toxicity in human and animals. in this study, the protectiveeffects of vitamin c and n-acetylcysteine (nac) on the toxicity of rifampin on hepg2 cellswere investigated.human hepatoma cells (hepg2) were cultured in 96-well m of rifampin in the presence ofmicroplate and expose...
Objective(s): Diabetes is a metabolic disease with an increasing prevalence for which finding new and efficient therapeutic approaches has always been a challenge. Preserving integrity and functionality of pancreatic β-cells as the only source of insulin in the body is such a case. To achieve this goal different cellular targets have been proposed among which pancreatic estrogen receptors have ...
Crocin, the main constituent of saffron (Crocus sativus L.), is a natural carotenoid which is known for its antioxidant activity. Liver as the organ that metabolizes many chemicals is one of the first position that is at risk of environmental pollutants. It is clear that compounds that exhibit antioxidant properties, scavenging of free radicals and inhibition of lipid peroxidation are expected ...
