A Comparative Analysis of Photobiomodulation-Mediated Biological Effects of Single Versus Double Irradiation on Dental Pulp Stem Cells: An Study.

In recent years, fractionated irradiation protocols, rather than a simple plan of exposure, have been proposed as a more effective method in the field of tissue regeneration. Thus, this study aimed at a comparative analysis of single versus double irradiation of an 808-nm diode laser, in terms of dental pulp stem cells' (DPSCs) viability and proliferation . Subcultured DPSCs were either irradiated, or not (control group), with energy densities of 3, 7, and 12 J·cm in a single- or double-session manner (24 h apart).

G-CSF augments the neuroprotective effect of conditioned medium of dental pulp stem cells against hypoxic neural injury in SH-SY5Y cells.

Objectives: Dental pulp stem cells (DPSCs) can differentiate into functional neurons and have the potential for cell therapy in neurological diseases. Granulocyte colony-stimulating factor (G-CSF) is a glycoprotein family shown neuroprotective effect in models of nerve damage.we evaluated the protective effects of G-CSF, conditioned media from DPSCs (DPSCs-CM) and conditioned media from transfected DPSCs with plasmid encoding G-CSF (DPSC-CMT) on SH-SY5Y exposed to CoCl as a model of hypoxia-induced neural damage.

Evaluation of the Cytotoxic and Apoptogenic Effects of Glabridin and Its Effect on Cytotoxicity and Apoptosis Induced by Doxorubicin Toward Cancerous Cells.

In the present study, we tried for the first time to examine the anti-proliferative and anti-apoptogenic effect of Glabridin (Glab) toward three groups of cancer cells (SKNMC, H1299, and A2780). Furthermore, the possibility of co-administration of Glab with doxorubicin (DOX) to these cells was also examined to find out whether Glab can potentiate the cytotoxic effect of this chemotherapy agent. Different cellular assays (MTT, caspase-3 activity, MMP, RT-PCR analysis) were carried out on the cancer cells treated with Glab.

The Protective Effect of Different Extracts of Three Species against HO-Induced Oxidative Stress and Apoptosis in PC12 Neuronal Cells.

Background: Oxidative stress causes cell damage and is involved in many neurological diseases. The antioxidant properties of plant materials for the maintenance of health and protecting against different diseases stimulated scientist to investigate different herbs. Different species have exhibited antioxidant activity.

Bioassay-guided Isolation of Neuroprotective Fatty Acids from against 1-methyl-4-phenylpyridinium-induced Neurotoxicity.

Objective: Parkinson's disease, a slowly progressive neurological disease, is associated with degeneration of the basal ganglia of the brain and a deficiency of the neurotransmitter dopamine. The main aspects of researches are the protection of normal neurons against degeneration. Fatty acids (FAs), the key structural elements of dietary lipids, are carboxylic straight chains and notable parameters in nutritional and industrial usefulness of a plant.

Protective effect of bioactive compounds from against cisplatin-induced oxidative stress and apoptosis in the PC12 cell line.

Objectives: The present study aims to evaluate the protective effect of the compounds isolated from () against oxidative stress and apoptosis induced by cisplatin (CIS) in PC12 cells.

Materials And Methods: Six compounds were isolated as quercetrin-3---D-glucopyranoside (QUE), osthol (OST), verbenone-5---D-glycopyranoside (VER), Isoimperatorin (ISO), kaempferol-3---D-glucopyranoside (KAM), and echinophorin B (ECH). For this study, we used MTT reduction assay for detection of protective effects of isolated compounds on CIS-induced cytotoxicity in PC12 cells.

Synthesis and Biological Evaluation of -(5-(pyridin-2-yl)-1,3,4-thiadiazol-2-yl)benzamide Derivatives as Lipoxygenase Inhibitor with Potential Anticancer Activity.

In the recent years, the role of LOX enzymes in the origin of neoplastic diseases such as colorectal, skin, pancreatic and renal cancers has been confirmed. A new series of 1,3,4-thiadiazole derivatives bearing 2-pyridyl moiety was synthesized and the cytotoxicity of the members of this series was assessed using MTT protocol. Enzyme inhibitory activity of the prepared compounds was also tested against 15-lipoxygenase-1 as a novel target for the discovery of anticancer drugs.

Protective effects of fractions from Artemisia biennis hydro-ethanolic extract against doxorubicin-induced oxidative stress and apoptosis in PC12 cells.

Objectives: This study was designed to indicate whether different fractions from Artemisia biennis hydroethanolic extract could provide cytoprotection against oxidative stress and apoptosis induced by doxorubicin (DOX) in rat pheochromocytoma cell line (PC12).

Material And Methods: Cell viability was determined by MTT assay. Also, activation of caspase-3 and superoxide dismutase were evaluated by spectrophotometry.

Phthalimide analogs as probable 15-lipoxygenase-1 inhibitors: synthesis, biological evaluation and docking studies.

Background: Recent studies have been explained the role of lipoxygenases (LOX) in the origin of cancer. Among the lipoxygenases, the 5-LOX, 12-LOX and 15-LOX are more important in the cause of neoplastic disorders. In the present investigation, a new series of anticancer agents with 1,3,4-thiadiazole and phthalimide substructures were synthesized and their in vitro cytotoxicity was evaluated by MTT assay.

Histopathologic and sonographic analysis of laparoscopic removal ovarian nonendometriotic cyst: the evaluating effects on ovarian reserve.

Currently, laparoscopic cystectomy is the first-line therapy for ovarian benign cysts that are resistant to current therapies. There are different studies that point to ovarian reserve damage due to laparoscopic cystectomy. In this study, we evaluate the ovarian damage following laparoscopic cystectomy for non-endometriosis cysts using ultrasound and pathology findings.

Extracts of Artemisia ciniformis Protect Cytotoxicity Induced by Hydrogen Peroxide in H9c2 Cardiac Muscle Cells through the Inhibition of Reactive Oxygen Species.

Objective. Artemisia ciniformis (Asteraceae) and A. biennis are two of 34 Artemisia species growing naturally in Iran.

Performance of pregnant women on folic acid intake.

The cause of neural tube defects (NTDs) is multifactorial and in this case folic acid has an important role. Since the neural tube is closed during 21-28 days of pregnancy, most of women are not informed about their pregnancy at this time, and as a result the golden time of folic acid consumption is missed. The aim of this study was evaluating the performance of pregnant women attending to Tehran Women's Hospital in regard to folic acid intake during pre-conceptional period between 2011 and 2012.
