OBJECTIVE: This study investigated the quercetin (Que) effects on growth of MCF-7 human cancer breast cell line and its cellular death mechanism. BACKGROUND: Quercetin has been found to be very efficacious against many different types of cancer cells. However, the study is not sufficiently powered to demonastrate anticancer mechanisms. METHODS: MCF-7cells were treated by 50 µM/ ml of Que for 48 hours. MCF-7 cells were also pretreated with 10 Μm ZVAD (apoptosis inhibitor) or 3 mM Nec-1 (necroptosis inhibitor) for evaluation of cell death induced by apoptosis or necroptosis...

OBJECTIVE: Spinal epidural fibrosis is a clinical condition that develops after laminectomy and can compress the spine. Many agents have been tried for the treatment, but none has entered clinical use at present. Pegaptanib sodium is an antiangiogenetic drug that prevents the development of new vessels and thus adhesion by inhibiting the effect of VEGF. MATERIAL AND METHOD: 20 Wistar rats were used in this study. The rats were divided into 2 different groups as the control and pegaptanib sodium group...

AIM: Increased intracranial pressure following trauma and subsequent possible development of brain death are important factors for morbidity and mortality due to ischemic changes. We aimed to establish the role of ischemic modified albumin (IMA) in the early diagnosis of the process, starting with increased intracranial pressure and ending with brain death. MATERIALS AND METHODS: Eighteen Wistar-Albino rats were divided into three groups; control (CG, n = 6), increased intracranial pressure (ICPG, n = 6), and brain death (BDG, n = 6)...

OBJECTIVE: For epileptics, pregnancy contains the balance between no seizure period and antiepileptic use having the least teratogenicity risk. The purpose is to analyse with flow cytometry the apoptotic effects on postnatal brain tissue caused by prenatal use of second generation antiepileptics oxcarbazepine (OXC) and gabapentin (GBP) having different effect mechanisms. METHOD: 30 (n = 5 each group) Wistar albino male rats (45-days-old) are used. First 3 groups are exposed to OXC (100 mg/kg/day), GBP (50 mg/kg/day), and saline, respectively on the 1st-5th prenatal days (preimplantation-implantation period) while the second 3 groups are exposed to the same substances on the 6th-15th prenatal days (organogenesis), respectively...

The role of vitamin D in calcium absorption and bone health is known. The studies revealed that vitamin D modulates breast cancer cell growth and it is also associated with a reduced breast cancer risk. The primary objective of this study was to highlight the metabolic effect of Vitamin D on MCF-7 breast cancer cell line. For that purpose, we checked the apoptosis, energy, amino-acid and acylcarnitine levels in cancer cells, that the study propose, that 1α, 25(OH)2D3 could inhibit cell growth in a dose and time dependent manner...

INTRODUCTION:   Renal cell cancer (RCC) is not a single entity, but consists of different types of tumors derived from various parts of the nephron (epithelium or renal tubules). It is known that cancer initiation and progression is related to the balance between oxidants and antioxidants directly. Interestingly, advanced stages of cancer such as metastasis, angiogenesis are associated with cell oxidative capacity. Familiar antioxidative substances such as carotenes and vitamin C inhibit oxidation of other molecules during carcinogenesis...

NTRODUCTION:   Obesity is one of the most serious public health problem worldwide. Adipose tissue synthetize and secrete many growth factors and several cytokines known as adipokines. Studies demonstrated changes in the levels of these adipokines in many types of cancer associated with obesity. In this study, we aimed to evaluate the possible relationship between adiponectin and leptin levels with pancreas cancer and disease stage, representative of Turkish population. MATERIALS AND METHODS:   The study was conducted between April 2012 - November 2013...
