Cobalt oxide nanoparticles aggravate DNA damage and cell death in eggplant via mitochondrial swelling and NO signaling pathway

Biol. Res; 49 (), 2016
BACKGROUND: Despite manifold benefits of nanoparticles (NPs), less information on the risks of NPs to human health and environment has been studied. Cobalt oxide nanoparticles (Co3O4-NPs) have been reported to cause toxicity in several organisms. In this study, we have investigated the role of Co3O4-NPs ...

The anti-cancerous activity of recombinant trichosanthin on prostate cancer cell PC3

Biol. Res; 49 (), 2016
CONTEXT: Trichosanthin produced in the root tube of Trichosanthes kirilowii shows anti-tumor activity on a series of cancer cells including Hela, MCF-7, HL-60. But there is little information about its effect on the carcinogenesis of prostate cancer. OBJECTIVE: This work was designed to study the role of...

Effects and molecular mechanism of chitosan-coated levodopa nanoliposomes on behavior of dyskinesia rats

Biol. Res; 49 (), 2016
BACKGROUND: Chitosan, the N-deacetylated derivative of chitin, is a cationic polyelectrolyte due to the presence of amino groups, one of the few occurring in nature. The use of chitosan in protein and drug delivery systems is being actively researched and reported in the literature RESULTS: In this study...

Growth hormone in the presence of laminin modulates interaction of human thymic epithelial cells and thymocytes in vitro

Biol. Res; 49 (), 2016
BACKGROUND: Several evidences indicate that hormones and neuropeptides function as immunomodulators. Among these, growth hormone (GH) is known to act on the thymic microenvironment, supporting its role in thymocyte differentiation. The aim of this study was to evaluate the effect of GH on human thymocyte...

Potential role of marine algae extract on 3T3-L1 cell proliferation and differentiation: an in vitro approach

Biol. Res; 49 (), 2016
BACKGROUND: From ancient times, marine algae have emerged as alternative medicine and foods, contains the rich source of natural products like proteins, vitamins, and secondary metabolites, especially Chlorella vulgaris (C. vulgaris) contains numerous anti-inflammatory, antioxidants and wound healing sub...

Anti-inflammatory effects of Salvia plebeia R. Br extract in vitro and in ovalbumin-induced mouse model

Biol. Res; 49 (), 2016
BACKGROUND: Asthma is an increasing global health problem, and novel strategies to prevent or ameliorate the condition are needed. Here, the effects of 80 % ethanol extracts of Salvia plebeia R. Br. (SE) on an induced inflammatory response were investigated RESULTS: Salvia plebeia R. Br. inhibited produc...

Cadmium-induced apoptosis of Siberian tiger fibroblasts via disrupted intracellular homeostasis

Biol. Res; 49 (), 2016
BACKGROUND: Heavy metals can cause great harm to Siberian tigers in the natural environment. Cadmium (Cd2+) is an environmental contaminant that affects multiple cellular processes, including cell proliferation, differentiation, and survival. It has been shown to induce apoptosis in a variety of cell typ...

In vitro assessment of a computer-designed potential anticancer agent in cervical cancer cells

Biol. Res; 49 (), 2016
BACKGROUND: Computer-based technology is becoming increasingly essential in biological research where drug discovery programs start with the identification of suitable drug targets. 2-Methoxyestradiol (2ME2) is a 17ß-estradiol metabolite that induces apoptosis in various cancer cell lines including cerv...

Pharmacological study of the mechanisms involved in the vasodilator effect produced by the acute application of triiodothyronine to rat aortic rings

Braz. j. med. biol. res; 49 (8), 2016
A relationship between thyroid hormones and the cardiovascular system has been well established in the literature. The present in vitro study aimed to investigate the mechanisms involved in the vasodilator effect produced by the acute application of 10-8–10-4 M triiodothyronine (T3) to isolated rat...

Renin-angiotensin system blockers regulate the metabolism of isolated fat cells in vitro

Braz. j. med. biol. res; 49 (8), 2016
Due to the presence of the renin-angiotensin system (RAS) in tissues and its specific influence on white adipose tissue, fat cells are possible targets of pharmacological RAS blockers commonly used as anti-hypertensive drugs. In the present study, we investigated the effects of different RAS blockers on ...
