OBJECTIVES: The role of aluminum (Al) in the pathogenesis of neurodegenerative diseases has been implicated in several studies. However, the exact mechanisms of cytotoxic effects of Al have not been elucidated yet. The aim of this study was to investigate the effect of L-type calcium channel antagonist, nimodipine (NM), and lithium chloride (LiCl) on Al-induced toxicity in PC12 cells. MATERIALS AND METHODS: PC12 cells were treated with Al-maltolate (Almal) in the presence and absence of different concentrations of NM (50-150 μm) and/or LiCl (0...

OBJECTIVES: Renal cell carcinoma (RCC) is insensitive to conventional chemotherapy. Ginkgetin effectively treats several carcinoma cells. However, little is known about effects of Ginkgetin on RCC. In the present study, using 786-O cells, we evaluate whether Ginkgetin exerts anticancer effects against RCC. MATERIALS AND METHODS: 786-O cells suspended in the medium containing Ginkgetin were cultured for 24 hr to 72 hr, and then MTT assay was used to study cytotoxic effect of Ginkgetin...

OBJECTIVES: Interleukin-12 (IL-12) as a cytokine has been proved to have a critical role in stimulating the immune system and has been used as immunotherapeutic agents in cancer gene therapy. Chitosan as a polymer, with high ability of binding to nucleic acids is a good candidate for gene delivery since it is biodegradable, biocompatible and non-allergenic polysaccharide. The objective of the present study was to investigate the effects of cells transfected with IL-12 loaded chitosan nanoparticles on the regression of fibrosarcoma tumor cells (WEHI-164) in vivo...

OBJECTIVES: As T-cell immunoglobulin and mucin domain 3 (TIM-3) is an immune regulatory molecule; its blocking or stimulating could alter the pattern of immune response towards a desired condition. Based on the unique features of nanobodies, we aimed to construct an anti-TIM-3 nanobody as an appropriate tool for manipulating immune responses for future therapeutic purposes. MATERIALS AND METHODS: We immunized a camel with TIM-3 antigen and then, synthesized a VHH phage: mid library from its B cell's transcriptome using nested PCR...

OBJECTIVES: Although many researchers have confirmed induction of germ cells from bone marrow mesenchymal stem cells (BMMSCs), there are no reports that confirm spontaneous differentiation of germ cells from BMMSCs. In this study, we have evaluated the effect of adult Sertoli cell condition medium (SCCM) as a mutative factor in the induction of germ cells from BMMSCs. MATERIALS AND METHODS: BMMSCs were collected from the bone marrow of 6-8-week old NMRI mice and their mesenchymal entities were proven using superficial markers (expression of CD44 and CD73 and non-expresion of CD45 and CD11b) by fow cytometry...

REVIEW
Feyza Bora, Fatih Yılmaz, Taner Bora
Ecstasy (MDMA; 3,4-methylenedioxymethylamphetamine) is an illicit drug that has been increasingly abused by young people. Its effects include euphoria, enhanced sociability and heightened mental awareness. These come about via the increase of serotonin in both the central nervous system and the sympathetic nervous system. Despite the drug's prevalent abuse, serious or adverse effects are rare. Due to personal pharmacokinetics, effects from the same dosage vary according to the individual. Fatal instances may include acute hyponatremia, hyperthermia (>42 °C), disseminated intravascular coagulation (DIC) resulting from hyperthermia affecting the kidneys, and non-traumatic rhabdomyolysis...

OBJECTIVES: Similar characteristics of molecular pathways between cellular reprogramming events and tumorigenesis have been accentuated in recent years. Reprogramming-related transcription factors, also known as Yamanaka factors (OCT4, SOX2, KLF4, and c-MYC), are also well-known oncogenes promoting cancer initiation, progression, and cellular transformation into cancer stem cells. Long non-coding RNAs (lncRNAs) are a major class of RNA molecules with emerging roles in stem cell pluripotency, cellular reprogramming, cellular transformation, and tumorigenesis...

OBJECTIVES: Sugar cane molasses is a commonly used ingredient in several food products. Contrasting reports suggest that molasses may have potential adverse or beneficial effects on human health. However, little evidence exists that examines the effects of molasses on the different physiological systems. This study investigated the effects of sugar cane molasses on various physiological systems using in vivo and in vitro methods. MATERIALS AND METHODS: Molasses was administered orally to BALB/c, male mice and animals were randomly assigned into either a treatment or control group...
