Abstract
BACKGROUND Ovarian cancer is the leading cause of gynecological cancer deaths. One of the major challenges in treating ovarian cancer with chemotherapy is managing the resistance developed by cancer cells to drugs, while also minimizing the side effects caused by these agents In the present study, we aimed to examine the effects of a combination of alpha lipoic acid (ALA), with cisplatin and paclitaxel in ovarian cancer(OVCAR-3). METHODS The cytotoxic effects of ALA, cisplatin and paclitaxel on OVCAR-3 cells were determined. Four groups were formed: Control, ALA, Cisplatin + Paclitaxel, ALA + Cisplatin + Paclitaxel. The effects of single and combined therapy on cell migration, invasion and colony formation were analyzed. Changes in the expression of genes related to apoptosis, cell adhesion and cell cycle were analyzed with Real-time polymerase chain reaction(RT-PCR). The oxidative stress index and The Annexin V test were performed. RESULTS The reduction in rapamycin-insensitive companion of mTOR(RICTOR) expression in the ALA + Cisplatin + Paclitaxel group was found statistically significant(p < 0.05). The decrease in MMP-9 and - 11 expressions the ALA + Cisplatin + Paclitaxel group was statistically significant(p < 0.05). The lowest values for mitogen-activated protein kinase(MAPK) proteins were found in the ALA + Cisplatin + Paclitaxel group. No colony formation was observed in the Cisplatin + Paclitaxel and ALA + Cisplatin + Paclitaxel groups. The lowest wound healing at 24 h was seen in the ALA + Cisplatin + Paclitaxel group. CONCLUSIONS This study is the first one to investigate the combined treatment of ALA, Cisplatin, Paclitaxel on OVCAR-3. While ALA alone was not effective, combined therapy with ALA, has been found to reduce cell invasion, especially wound healing in the first 24 h, along with tumor cell adhesion.

Abstract
BACKGROUND Ovarian cancer is the fifth leading cause of cancer-related death in women. Patients are usually diagnosed with advanced tumor metastass. Epithelial over cancer cells spread from primary tumor by undergoing epithelial mesenchymal transition (EMT). It has been suggested that alpha lipoic acid (ALA), a natural antioxidant lipophilic compound, reduces the oxidative stress by causing apoptosis and inhibition of proliferation of cell in cancer cells. The aim of our study was to establish a transforming growth factor β1 (TGF β1) dependent epithelial mesenchymal transition model in the SKOV-3 ovarian adenocarcinoma cell line which is an epithelial subtype of ovarian cancer and to investigate the effects of alpha lipoic acid on EMT and ovarian cancer migration. METHODS For establish an EMT model, SKOV-3 cells were treated with different dose of TGF β1 and XTT cell viability kit was used to find IC 50 dose of ALA. Four different groups that are control, TGF β1, ALA and ALA + TGF β1 were created. Changes in the expression of genes related to EMT markers that are E-cadherin, vimentin, Snail, Slug, Twist and Zeb were analyzed with quantitative real-time PCR. These proteins were determined with the immunocytochemistry method. The migration capacity was analyzed with wound healing assay. Matrigel invasion capacity test was used to show invasion and colonization test to show colonization. RESULTS The dose of TGF β1 was determined 100 ng/ml at 72 h, the IC50 dose of ALA 219.033 µM at 48 h was determined. EMT markers in the TGF β1 group were compatible with EMT and it was shown to inhibit EMT in the groups given ALA. According to wound healing, colonization and invasion experiments, proliferation and invasion increased in TGF β1 group, but decreased in ALA and combined groups (p < 0.05). CONCLUSION These results indicate that ALA suppresses the metastasis of ovarian cancer cells by regulating EMT, implying that ALA might be a potential therapeutic agent for the treatment of ovarian cancer.

Abstract
OBJECTIVES Stem cell treatment is based on Melatonin which is crucial for lots of pathological and physiological pathways. Our aim is determining the most appropriate dose of melatonin affecting the rat adipose tissue mesenchymal stem cells. METHODS Stem cells were isolated from male rat adipose tissue. Differentiation and characterization experiments were performed. Cell viability analyses in stem cells were used the XTT [2,3-Bis-(2-methoxy-4-Nitro-5-Sulfophenyl)-2H-Tetrazolium-5-Carboxanilide] assay. After 24 h incubation, different concentrations (0.5, 1, 5, 10, 50 µM) of extract were treated to the stem cells for 24 h, 48 and 72 h considering time and dose dependent manner. Total antioxidant status (TAS) and the total oxidant status (TOS) in control cells and melatonin treated cells (5, 10 µM) were determined Rel Assay commercial kits. RESULTS In 24 h, melatonin increased cell viability in all groups. When we evaluate the effect of melatonin in 48 h, the most proliferation increase was seen at 5, 10 µM doses. When the total oxidant activity melatonin was found to be significantly lower in 5 and 10 µM dose groups of melatonin. CONCLUSIONS Melatonin increases the survivor of stem cells and the most effective dose is 5 and 10 µM. The reduction of the oxidative stress index as a result of treating melatonin to mesenchymal stem cells showed that melatonin is a powerful antioxidant for stem cells.

Abstract
Our aim is to investigate the effect of the Mesenchymal stem cell (MSC) administration on the release of Mammalian Target of Rapamycin (mTOR) and Phosphorylated- mTOR(p-mTOR) in Cyclophosphomide (CTX) induced ovarian damage. Rats divided into three groups. The first group was categorized as the control(C group;n = 6), the second group as CTX-administered group (CTX group;n = 6), and the third group as CTX and MSC-administered group (CTX + SC group;n = 6). CTX was injected intraperitoneally at 50 mg/kg on the first day and at 8 mg/kg during the following 13 days. In Group 3, adipose-derived MSCs (5 × 104) were injected locally into the ovary. Both ovaries were removed at the end of the 8th week. The follicle count was made. The expression of mTOR and p-mTOR was analyzed immunohistochemically. The follicles in the ovary of Group C were observed in normal structures. Degeneration was evident in the CTX group. In the CTX + SC group, the degenerative appearance monitored in the CTX group vanished in most areas, and fibrosis was greatly reduced. The number of follicles in the CTX group was lower than that of both C and CTX + SC groups (p < 005). In the C group, mTOR showed strong positive staining while mTOR and p-mTOR expression was negative in all follicles in the CTX group. Both mTOR and p-mTOR revealed moderate positive expression in the CTX + SC group. MSC therapy rescued the damage ovarian function created by CTX, reducing follicle loss. MSCs were shown to inhibit the loss of mTOR and p-mTOR signaling, which is key to meiosis in oocytes.

Abstract
We aimed to evaluate the possible effects of seasonal variation on semen parameters. We retrospectively analysed the data of 6,116 semen samples collected at a university hospital for eight years. The past ambient temperature, relative humidity and daylight duration records, and birth registry of the province were obtained to examine the relationship of seasonal changes in semen parameters with annual birth rates and environmental factors. The mean age was 33.03 ± 6.86 years. We found a significant difference between months for sperm concentration (p < .0001), total sperm count (p < .0001), progressively motile sperm count (p < .0001) and normal sperm morphology (p = .028). The sperm concentration and total count were significantly lower in July and August compared with December, May and June. The progressively motile sperm count in October was 23.6% less than the value of May. The temperature and temperature-humidity index were negatively correlated with semen parameters. The highest number of births was in the summer. However, no correlation was present between deliveries and the semen concentration regarding months (rs = 0.199, p = .083). In conclusion, we observed significant seasonal and monthly differences in sperm concentration, sperm count and progressively motile sperm count. Increased ambient temperature due to seasonal changes may be a detrimental factor for semen parameters.

Abstract
The use of stem or progenitor cells from bone marrow, or peripheral or umbilical cord blood is becoming more common for treatment of diabetic foot problems. These cells promote neovascularization by angiogenic factors and they promote epithelium formation by stimulating cell replication and migration under certain pathological conditions. We investigated the role of CD34 + stem cells from human umbilical cord blood in wound healing using a rat model. Rats were randomly divided into a control group and two groups with diabetes induced by a single dose of 55 mg/kg intraperitoneal streptozocin. Scarred areas 5 mm in diameter were created on the feet of all rats. The diabetic rats constituted the diabetes control group and a diabetes + stem cell group with local injection into the wound site of 0.5 × 106 CD34 + stem cells from human umbilical cord blood. The newly formed skin in the foot wounds following CD34 + stem cell treatment showed significantly improvement by immunohistochemistry and TUNEL staining, and were closer to the wound healing of the control group than the untreated diabetic animals. The increase in FGF expression that accompanied the local injection of CD34 + stem cells indicates that FGF stimulation helped prevent apoptosis. Our findings suggest a promising new treatment approach to diabetic wound healing.
