Kinetics of single cell protein production from natural gas by a microorganism (a Methylomonas sp.) was studied experimentally and by modeling at equal amount of air and natural gas. Kinetic models of Monod, Moser, Teissier, Aiba, Andrews, and Noack were used for illustrating cell growth. Methane and oxygen were considered as limited substrates with concentration in the range 2-10 mg/lit. Death...

Background and Objective: Excessive production of free radicals during oxidative stress can cause serious damage to important biomolecules and activate programmed cell death pathways in the body. In the nervous system, neuronal cell death leads to many progressive neurodegenerative disorders. The aim of this study was to evaluate the effects of adenosine on the inhibition of apoptosis in oxidat...

Background & aim: Cancer is a disharmony amongst cell growth and death which results in accumulation of cells. Bone cancer is an absolutely dangerous type of cancer and occurs when the bone-making cells are disrupted. Despite some reports on the anticancer effects of simvastatin, the activity of simvastatin on bone cancer cells has not been reported. The aim of this study was to evaluate the cy...

Introduction: Astrocytes have an important role in many neurodegenerative diseases. Active astrocytes release inflammatory factors such as NO and ILs. Shikonin, a naphthoquinone pigment of Lithospermum erythrorhizon roots has anti-inflammatory and antitumoral effects. The present study aims to investigate the anti-inflammatory and toxic effects of Shikonin on cultured astrocytes. Methods...

objective: glioblastoma multiforme (gbm), one of the most common and aggressive malignant brain tumors, is highly resistant to radiotherapy. numerous approaches have been pursued to find new radiosensitizers. we used a picogreen and colonogenic assay to appraise the dna damage and cell death in a spheroid culture of gbm cells caused by iodine-131 (i-131) beta radiation in the presence of topote...

Background and purpose: Adenocarcinoma gastric cancer is one of the most common cancers of upper gastrointestinal tract. Many natural compounds are known to have anti-tumor activities through induction of tumor cell apoptosis. Tribulus terrestris is a plant with antioxidant and anti-inflammatory effects that has been recommended in the world and Iranian traditional medicine. These effects have ...

Introduction: Cancer, the uncontrolled division of cells, occurs because of environmental factors and genetic disorders. Breast cancer is the most common cancer and the second leading cause of cancer death in women. Four categories of key genes, including oncogenes, tumor suppressor genes, repairing genes, and programmed– cell death genes, contribute to cancer development. Bromoacetic acid is a...

calprotectin, a calcium-bound protein complex, is abundant in the cytosol of neutrophils. it has been reported that this protein has an apoptotic activity in tumor cells. since calprotectin increases in colorectal cancer, this study was conducted to investigate, for the first time, the cytotoxicity/apoptotic effect of calprotectin on ht29/219 and sw742 colon carcinoma and adenocarcinoma cell li...
