Co-exposure to deltamethrin and thiacloprid induces cytotoxicity and oxidative stress in human lung cells.

Deltamethrin (DEL) and thiacloprid (THIA) are commonly used synthetic insecticides in agriculture either separately or in combination. There is limited information in human cells for the effects of the mixture of DEL + THIA on oxidative stress. Therefore, the present study was designed to examine the effects of the mixture on cell proliferation and oxidative stress in human lung fibroblast cells.

Effects of Reverse Transcriptase Inhibitors on Proliferation, Apoptosis, and Migration in Breast Carcinoma Cells.

High telomerase activity in human breast cancer is associated with aggressive tumors resulting in decreased survival. Recent studies have shown that telomerase inhibitors may display anticancer properties in some human cancer cell lines. In the present study, we examined the effects of 4 reverse transcriptase inhibitors (RTIs), used for the treatment of HIV; Abacavir (AC), Lamivudine (LV), Stavudine (SV), and Tenofovir (TF) on proliferation, apoptosis, and migration in the normal human mammary epithelial cell line, hTERT-HME1, and the human breast cancer cell line, MCF-7.

Amoebicidal and Amoebistatic Effects of Artemisia argyi Methanolic Extracts on Acanthamoeba castellanii Trophozoites and Cysts.

Unlabelled: PURPOSE : The present study aimed to investigate the amoebicidal and amoebistatic efects of Artemisia argyi leaf methanolic extract by testing the effects on trophozoites and on cysts. We also determined cytotoxic effect, enzymatic and non-enzymatic antioxidant activities, total phenolic, lavonoid and antioxidative contents of A. argyi.

Cytogenetic alterations induced by flupyradifurone, a new butenolide insecticide, in human lymphocytes.

Flupyradifurone (FPD), a member of the new class of butenolide insecticides, acts on nicotinic acetylcholine receptors. Studies on genotoxic and carcinogenic effects of FPD are very limited. This is the first study to investigate the cytotoxic and genotoxic effects of FPD and its metabolites on human lymphocyte cultures with or without a metabolic activation system (S9 mix) using chromosomal aberration (CA) and micronucleus (MN) tests.

Argan oil reduces oxidative stress, genetic damage and emperipolesis in rats treated with acrylamide.

Acrylamide (AA), a well-known toxicant, is present in high-temperature-processed foods in heated foods. Argan oil (AO), a natural vegetable oil, is receiving increasing attention due to its powerful biological properties. However, limited information is available about its effects in lymphoid organs and bone marrow.

Effects of Viscum album L. extract and quercetin on methotrexate-induced cyto-genotoxicity in mouse bone-marrow cells.

Viscum album, a semi-parasitic plant, has been used both in traditional and supplementary medicine in the treatment of many diseases. Quercetin (QE), one of the major flavonoids in some fruits and vegetables, has anti-oxidative and anti-carcinogenic activities. Methotrexate (MTX), an anti-folate anti-metabolite, is a widely used anti-neoplastic drug with significant clastogenic effects.

Cytotoxic and genotoxic effects of high-frequency electromagnetic fields (GSM 1800 MHz) on immature and mature rats.

We investigated the cytogenotoxic effects of high frequency electromagnetic fields (HF-EMF) for 45 day and the effect of a recovery period of 15 day after exposure to EMF on bone marrow cells of immature and mature rats. The animals in treatment groups were exposed to 1800 MHz EMF at SAR of 0.37 W/kg and 0.

Genotoxic and cytotoxic effects of doxycycline in cultured human peripheral blood lymphocytes.

Doxycycline (DOX) is a broad-spectrum tetracycline antibiotic used in the treatment of many infections. In this study, the genotoxic and cytotoxic effects of DOX in cultured human peripheral blood lymphocytes were investigated by measuring chromosome aberrations (CAs), cytokinesis-block micronucleus (CBMN) assay, mitotic index (MI), and nuclear division index (NDI). Cultures were treated with DOX at three concentrations (2, 4, and 6 µg/mL) for 48 hours.

Cytogenetic effects of commercial formulations of deltamethrin and/or thiacloprid on Wistar rat bone marrow cells.

Deltamethrin (DEL) and thiacloprid (THIA) are two insecticides that are widely used in agriculture either separately or in combination. Studies on genotoxicity and cytotoxicity of TIA and the mixture of DEL and THIA insecticides have not been reported so far. Therefore, we investigated the cytotoxic and genotoxic effects of commercial formulations DEL and/or THIA in rat bone marrow cells, using mitotic index (MI), micronucleus (MN) and chromosome aberrations (CA) assay.

Evaluation of the genotoxicity and cytotoxicity of fexofenadine in cultured human peripheral blood lymphocytes.

Fexofenadine (FXF) is a new non-sedating antihistamine used in the treatment of seasonal allergic rhinitis and chronic idiopathic urticaria. Studies on FXF genotoxicity and cytotoxicity in cultured human peripheral blood lymphocytes have not been reported so far. Therefore, the present study is the first report investigating the genotoxic and cytotoxic effects of FXF in cultured human peripheral blood lymphocytes in vitro.

Viscum album L. extract and quercetin reduce cyclophosphamide-induced cardiotoxicity, urotoxicity and genotoxicity in mice.

Possible protective effects of a methanolic extract of Viscum album (VA) and quercetin (QE) against cyclophosphamide (CP) induced cardiotoxicity, urotoxicity and genotoxicity in mice were evaluated. Mice were administered orally VA (250 mg/kg/day) and QE (50 mg/kg/day) for 10 days alone or in combination with CP. After the same doses of VA and QE given for 7 days, rats were intraperitoneally administered CP (40 mg/kg) on days 8 and 9 of the experiment.

The antioxidant and antigenotoxic effects of pycnogenol(®) on rats treated with cisplatin.

Oxidative stress and inflammation are implicated in the pathogenesis of cisplatin-induced toxicity. Pycnogenol® is known for its strong antioxidant and anti-inflammatory effects. In this study, the possible protective effects of pycnogenol on kidney, bone marrow, and red blood cells in rats treated with cisplatin were investigated.

[Diagnosis of protozoa by loop-mediated isothermal amplification: (LAMP)].

Plasmodium, Isospora, Toxoplasma, Babesia and Cryptosporidium are parasites which have a significant role in human health. The location in which the protozoon settles in the body, the way that it leaves the host, and the sample which is send from the clinic are the elements of the general methods used in the diagnosis of the ailments caused from protozoan. Classical methods are not adequate for the identification of some protozoon; also, molecular methods have to be used in designating the distinctions between the species.
