Abstract
OBJECTIVE The objective of this study was to investigate the protectiveness of resveratrol on cisplatin-induced damage to the ovary using experimental models. METHODS A total of 30 female Wistar-Albino rats constituted the research material. The rats were categorized into three groups: Group 1 was administered one milliliter of 0.9% NaCl solution, Group 2 was administered 7.5 mg/kg cisplatin, and Group 3 was administered 7.5 mg/kg cisplatin and 10 mg/kg resveratrol. Ovaries were extirpated in all groups and subjected to biochemical and histopathological tests. Cisplatin-induced damage to ovarian tissue was graded and scored as the total histopathological findings score. The ovarian function was assessed using immunohistochemical staining for c-kit expression. Rats' malondialdehyde, catalase, and superoxide dismutase levels were determined. RESULTS The histopathological finding score was significantly higher in Group 2 than in other groups (p<0.05). The superoxide dismutase and catalase levels were significantly higher in Group 3 than in Group 2 (p<0.001 for both cases). The malondialdehyde level was significantly higher in Group 2 than in Group 3 (p<0.001). CONCLUSION The study findings demonstrated that resveratrol reduced ovarian injury and enhanced biochemical parameters following cisplatin-induced ovary damage in experimental models.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can potentially infect female reproductive organs. In this study, we investigated the presence of SARS-CoV-2 in cervicovaginal fluid. This study included 31 female patients aged 18–65 years. The presence of SARS-CoV-2 RNA was investigated by RT‒PCR in two separate cervicovaginal swab samples collected from patients 14 days apart. Viral RNA was extracted using Bio-Speedy ®vNAT® Viral Nucleic Acid Buffer (vNAT) solution, and SARS-CoV-2 RNA was analyzed using Bio-Speedy SARS-CoV-2 RT‒qPCR kits in a Bio-Rad CFX96 TouchTM device. First and second cervical swab samples were collected 14 days apart. The SARS-CoV-2 RNA result was negative in all 53 cervicovaginal swab samples collected. Negative SARS-CoV-2 RNA results in cervicovaginal swab samples indicate that coronavirus disease 2019 (COVID-19) is not sexually transmitted. However, the number of studies on this subject and the sample size examined are still insufficient for reaching this conclusion.

Abstract
The aim of this study is to assess the FNDC5 and myonectin expressions and serum levels of myonectin and irisin in women with PCOS. 90 participants were included in this case-control study. 45 of these participants were with PCOS, and 45 of them were healthy volunteers matched for age and body mass index (BMI). Serum irisin and myonectin levels were measured with commercially available enzyme-linked immune sorbent assay (ELISA) kits. Expression of the myonectin and FNDC5 genes were determined by RT-PCR analysis. It was found out that FSI, HOMA-IR, LH, LH/FSH, TT, serum irisin and serum myonectin levels, myonectin mRNA expression, and FNDC5 mRNA expression were higher in the PCOS group, whereas HDL-C level was lower in the PCOS group (p < .05). When the groups were compared, it was detected that IR and HA were significantly higher in the PCOS group (p < .05). Serum irisin and myonectin levels, and myonectin and FNDC5 mRNA expressions were increased in women with PCOS. These molecules can be target molecules in PCOS pathophysiology and treatment.IMPACT STATEMENTWhat is already known on this subject? Although the aetiology of PCOS is not fully understood, it is thought that insulin resistance may play a critical role. In recent studies, the relationship of cytokines secreted from skeletal muscle with insulin resistance has been shown. The effects of irisin and myonectin, which are members of the myokine family, on lipid and glucose metabolism are known.What do the results of this study add? Although there are many studies in the literature regarding serum irisin levels in women with PCOS, their results are confusing. There is a study in the literature investigating the relationship between myonectin and PCOS. In our study, we evaluated myonectin and FNDC mRNA expressions in addition to serum irisin and myonectin levels. As a result, we found that markers and their mRNA expressions were lower in patients with PCOS compared to controls.What are the implications of these findings for clinical practice and/or further research? We think that the results of our study will shed light on future studies. Due to their effects on adipose tissue, these markers may play a role in the aetiology of long-term complications of PCOS. Moreover, they can become pharmacological targets in preventing these complications.

Abstract
OBJECTIVE Coronavirus infections, including SARS, MERS and COVID-19 have significant impact on global health as well as on pregnancies. The aim of this review was to enlighten and summarize the cumulative knowledge regarding the relationship between Coronavirus outbreaks and pregnancy. MATERIALS AND METHODS Literature search was commenced in order to analyze the maternofetal effects of Coronavirus outbreaks. RESULTS Fever and cough are the most common presenting symptoms of COVID-19 which mostly affects pregnant women in their 3rd trimester with a maternal mortality rate of 0-77% and fetal and neonatal mortality rates of 1.2%. Fetal demise is common in critically ill pregnant. Pregnancy seems as a worsening factor for SARS and MERS epidemics and both infections affect prominently 3rd trimester pregnancies, although abortion (57%) is a significant risk for cases of early pregnancy. Clinical course of COVID-19, SARS and MERS may be rapid and worse in pregnant women than non-pregnant individuals. Cesarean section is the choice of delivery in most reported women due to mostly obstetrical reasons, although vaginal delivery seems not a worsening factor for the disease. CONCLUSIONS COVID-19, SARS and MERS have significant detrimental effect on pregnancy. Rapid intervention, treatment, and intensive care support are essential for infected pregnant. Timely delivery is important in order to avoid intrauterine fetal death.

Abstract
Objectives Endometrial cancer is the most frequent tumor of the female genital tract.
Ubiquitin is a small protein (8.5 kDa) found in all eukaryotic cells, binds
to substrate proteins via a three-phase enzymatic pathway referred to as
ubiquitination and plays an important role in cellular stability. Neural
precursor cell-expressed developmentally down-regulated 4-like (NEDD4L)
functions in the last phase of this enzymatic process. In this study, we
investigated NEDD4L protein expression in endometrial cancer. Methods The study participants were divided into patients with benign endometrial
pathologies (Group 1, n = 23), patients with endometrial hyperplasia (Group
2, n = 21) and patients with endometrial cancer (Group 3, n = 20). NEDD4L
expression was detected by immunohistochemical staining and H scores were
calculated to standardize staining intensity. Statistical analysis was
performed using SPSS 16.0. Results NEDD4L expression levels according to H scores were significantly lower in
patients diagnosed with endometrial cancer compared with those with benign
endometrial pathologies. Conclusion NEDD4L is involved in maintaining cell stability, and reduced NEDD4L
expression as a result of gene mutation may disrupt this balance in favor of
tumorigenesis.

Abstract
OBJECTIVE Evaluation of mean platelet volume (MPV), neutrophil to lymphocyte ratio (NLR), and platelet count in the detection of malignant and benign ovarian tumors. MATERIAL AND METHODS Sixty-six patients admitted to the present clinic over three years were in- cluded in the study. Patients diagnosed with ovarian cancer were grouped into the areas of epithelial and granulosa cell tumor diagno- sis. The values were compared to patients with benign cystic structure. Patients' preoperative hematologic parameters and their values four weeks postoperatively were analyzed. Statistical analyses were performed with SPSS software. RESULTS MPV, NLR, and platelet count were observed at a higher rate as statistically significant in patients diagnosed with malignant ovarian cancer, compared to those with benign adnexal mass. CONCLUSION The hemnatological parameters such as MPV, NLR, and platelet count in the detection of malignant ovarian tumors have been evaluated as useful new markers.
