Abstract
OBJECTIVES To investigate ALB gene variations in patients suspected from familial dysalbuminemic hyperthyroxinemia (FDH). METHODS Eight Turkish patients were included into the study. Clinical and laboratory characteristics of the subjects and their parents were evaluated and genetic analysis were performed. RESULTS In genetic analysis, a previously reported heterozygous, c.725G>A variant was detected in exon seven of the ALB gene. CONCLUSIONS FDH is an asymptomatic condition however there is still a risk of misdiagnosis and unnecessary treatment. Therefore, if FDH is considered, initial ALB hotspot sequencing as a rapid and simple method is recommended instead of complex and expensive laboratory and imaging techniques.

Humanin's impact on pain markers and neuronal viability in diabetic neuropathy model. Arch Physiol Biochem 2024:1-11. [PMID: 38599217 DOI: 10.1080/13813455.2024.2336922] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Accepted: 03/26/2024] [Indexed: 04/12/2024]
Abstract
OBJECTIVE This study investigates the impact of chronic humanin (HN) treatment on pain-related markers (NMDA, substance P, TRPV1, and IL-1β) in diabetic mice's dorsal root ganglia (DRG). Additionally, we assess the effects of HN on cellular viability in DRG neurons. METHODS In vivo experiments involved 15 days of HN administration (4 mg/kg) to diabetic mice (n = 10). Protein levels of NMDA, IL-1β, TRPV1, and substance P were measured in diabetic DRG. In vitro experiments explored HN's impact on apoptosis and cellular viability, focusing on the JAK2/STAT3 pathway. RESULTS Humanin significantly reduced the elevated expression of NMDA, IL-1β, TRPV1, and substance P induced by diabetes (p < .05). Furthermore, HN treatment increased cellular viability in DRG neurons through JAK2/STAT3 pathway activation (p < .05). CONCLUSION These findings highlight the significance of understanding mitochondrial function and pain markers, as well as apoptosis in diabetes. The study provides insights for managing the condition and its complications.

Abstract
OBJECTIVE This study aimed to analyze the clinical data and pathologic aspects of endometrial polyps (EMPs) excised completely during surgical hysteroscopy and assess the connection between premalignant and malignant EMPs. PATIENTS AND METHODS This retrospective study includes 489 participants who underwent hysteroscopy due to endometrial polyps, and the clinical features and histological findings of the resected polyps analyzed. RESULTS Participants with EMPs were divided into six groups according to histologic findings. The histologic finding of most cases was simple benign endometrial polyp [397 patients (81.2%)]. Malignant polyp was detected in 3 patients (0.6%). The histologic findings according to age, menopausal status, and menstrual bleeding patterns at the time of presentation to the outpatient clinic were compared; however, no significant difference was observed. 237 patients were observed to have menometrorrhagia, which was the most prevalent symptom reported. The distribution of polyp sizes observed at hysteroscopy according to histologic findings was compared, but no significant difference was observed. CONCLUSIONS EMPs are often benign but can include premalignant or malignant tissue changes. Hysteroscopy is used for direct observation of the uterine cervix and resection of existing polyps, considering the increasing frequency of its use as a diagnostic and treatment tool.

Central MOTS-c infusion affects reproductive hormones in obese and non-obese rats. Neurosci Lett 2024; 826:137722. [PMID: 38462167 DOI: 10.1016/j.neulet.2024.137722] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 03/06/2024] [Accepted: 03/07/2024] [Indexed: 03/12/2024]
Abstract
MOTS-c, a mitochondrial-derived peptide, acts as a systemic hormone and MOTS-c level is inversely correlated with markers of obesity. Obesity is a risk factor for male reproductive physiology and is expressed as an important cause of infertility. In this study, we aimed to determine the effects of MOTS-c, which has been proven in the hypothalamus and testicles, on the actors involved in the reproductive axis. In the study, 80 male Wistar-Albino rats were divided into two main groups, obese and non-obese (n = 40). Rats in the first main group were fed with fatty diet feed and obesity was induced. The second main group was fed with normal diet feed. Each main group was divided into 4 subgroups (Control, Sham, 10 and 100 µM MOTS-c). The lateral ventricles of the animals in the treatment groups were infused with 10 and 100 µM MOTS-c (solvent in Sham group) for 14 days. At the end of the experiment, hypothalamic Gonadotropin-Releasing Hormone (GnRH) gene expression level, serum testosterone, Luteinizing hormone (LH) and Follicle stimulating hormone (FSH) levels were determined. MOTS-c infusion caused an increase in GnRH mRNA, protein expression levels and serum testosterone, LH and FSH levels in obese and non-obese rats (p < 0.05). MOTS-c administration more significantly upregulated hormone levels in non-obese rats (p < 0.05). MOTS-c administration increases these hormones, suggesting that MOTS-c may stimulate the reproductive axis. Our results reveal that MOTS-c plays a role in the central regulation of reproduction, as well as causes increased LH, FSH and testosterone release.

Abstract
OBJECTIVE Cerebral ischemia (CI) is a condition in which metabolic stress increases when blood flow is interrupted in a part of the brain, resulting in oxygen and glucose deprivation. It is known that asprosin (Asp), secreted from adipose tissue during fasting, has an effect on some metabolic processes such as apoptosis, autophagy, and glucose metabolism. This study aimed to explain which of the cell death/survival Asp induces in the CI/reperfusion model. MATERIALS AND METHODS In the study, 48 male Wistar Albino rats were divided into 6 groups: Sham, CI, Asp+CI, CI+Asp, CI+Asp+3-MA, and Asp+CI+3-MA (n=48). CI was created using the intraluminal filament technique for 60 minutes, autophagy inhibitor 3-MA (15 mg/kg/day) and Asp (1 µg/kg/day) injections were administered 3 days before or 3 days during reperfusion. Beclin-1, ATG5, ATG7, p62, Bcl-2, Bax, active-caspase-3, and active-caspase-9 protein levels from brain tissues were determined by the Western-Blot method. The infarct area was determined by triphenyl tetrazolium chloride (TTC) staining. The Kruskal-Wallis' test was used to compare differences between groups. p<0.05 was considered statistically significant. RESULTS Compared to the Sham group, the increase in ischemic area and the decrease in Beclin-1, ATG-5, ATG-7, Bcl-2, Bax, active-caspase-3 and active-caspase-9 levels in the CI groups are statistically significant (p<0.05). The increase of Beclin-1, ATG-7, Bcl-2, and Bax levels in the Asp groups is statistically significant compared to the CI group (p<0.05). When Asp+CI groups and CI+Asp groups are compared, an increase in Beclin-1 levels in the Asp+CI group and the increase in Bcl-2, Bax, active-caspase-3/9 and ATG-5 levels in the CI+Asp groups are statistically significant (p<0.05). CONCLUSIONS Asp has protective and therapeutic effects against CI/R damage. While applying Asp before ischemia activates the autophagy pathway more, applying it after ischemia protects the neuronal death/survival balance by activating the apoptosis pathway more.

Abstract
Synthesis of four sulfa drug derivatives (L1-L4) and Zn(II) complexes derived from sulfonamide group antibiotic substances was carried out using the hydrothermal technique (HT) and their structures of the obtained compounds were explained using elemental analysis (EA), FT-IR and NMR (1H- and 13C-). Cytotoxic activities of four novel sulfa drug based-Schiff base compounds and their Zn(II) complexes were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay using MCF-7 (human breast cancer), Caco-2 (human colorectal adenocarcinoma), A2780 (human ovarian cancer) and LNCaP (human prostate adenocarcinoma) cell lines. LogIC50 values of all obtained compounds were computed with the Graphpad Prism 6 program after 24 h of treatment for MCF-7, Caco-2, A2780 and LNCaP cells. Comet assay experiments were performed using LogIC50 concentrations of all compounds to determine DNA damage. Based on the data obtained, all compounds significantly decreased MCF-7, Caco-2, A2780 and LNCaP cell viability compared to the control groups (p < 0.05).

Modulation of Neuronal Damage in DRG by Asprosin in a High-Glucose Environment and Its Impact on miRNA181-a Expression in Diabetic DRG. Neurotox Res 2023; 42:5. [PMID: 38133838 DOI: 10.1007/s12640-023-00678-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 10/09/2023] [Accepted: 12/02/2023] [Indexed: 12/23/2023]
Abstract
Asprosin, a hormone secreted from adipose tissue, has been implicated in the modulation of cell viability. Current studies suggest that neurological impairments are increased in individuals with obesity-linked diabetes, likely due to the presence of excess adipose tissue, but the precise molecular mechanism behind this association remains poorly understood. In this study, our hypothesis that asprosin has the potential to mitigate neuronal damage in a high glucose (HG) environment while also regulating the expression of microRNA (miRNA)-181a, which is involved in critical biological processes such as cellular survival, apoptosis, and autophagy. To investigate this, dorsal root ganglion (DRG) neurons were exposed to asprosin in a HG (45 mmol/L) environment for 24 hours, with a focus on the role of the protein kinase A (PKA) pathway. Expression of miRNA-181a was measured by using real-time polymerase chain reaction (RT-PCR) in diabetic DRG. Our findings revealed a decline in cell viability and an upregulation of apoptosis under HG conditions. However, pretreatment with asprosin in sensory neurons effectively improved cell viability and reduced apoptosis by activating the PKA pathway. Furthermore, we observed that asprosin modulated the expression of miRNA-181a in diabetic DRG. Our study demonstrates that asprosin has the potential to protect DRG neurons from HG-induced damage while influencing miRNA-181a expression in diabetic DRG. These findings provide valuable insights for the development of clinical interventions targeting neurotoxicity in diabetes, with asprosin emerging as a promising therapeutic target for managing neurological complications in affected individuals.

Abstract
Arm swing and energy consumption play an important role in the realization of an effective gait. However, research on arm swing and energy consumption during gait in individuals with adolescent idiopathic scoliosis (AIS) is limited. The aim of this study was to investigate the spatiotemporal characteristics of gait, arm swing angles in the sagittal plane, energy consumption in individuals with AIS, to compare them with their healthy peers in this regard. 26 diagnosed with AIS and 21 healthy were included in this study. Evaluation measures were based on the Cobb angle, axial trunk rotation, trunk symmetry, sagittal curve measurements, spatiotemporal characteristics of gait with the GAITRite electronic walkway, sagittal plane arm swing with two video-camera recordings, and energy consumption. There were a decrease in right- sided sagittal arm swing, an increase in energy consumption, in left-side step time and right-side double support time in the scoliosis group compared to the control group. The other spatiotemporal characteristics of the gait were similar in both groups. The evaluation of arm swing, energy consumption, and gait of individuals with AIS may contribute to the development of rehabilitation programs by better identifying the deficiencies of individuals with AIS.

Molsidomine decreases hyperoxia-induced lung injury in neonatal rats. Pediatr Res 2023; 94:1341-1348. [PMID: 37179436 DOI: 10.1038/s41390-023-02643-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 04/11/2023] [Accepted: 04/17/2023] [Indexed: 05/15/2023]
Abstract
BACKGROUND The study's objective is to evaluate if Molsidomine (MOL), an anti-oxidant, anti-inflammatory, and anti-apoptotic drug, is effective in treating hyperoxic lung injury (HLI). METHODS The study consisted of four groups of neonatal rats characterized as the Control, Control+MOL, HLI, HLI + MOL groups. Near the end of the study, the lung tissue of the rats were evaluated with respect to apoptosis, histopathological damage, anti-oxidant and oxidant capacity as well as degree of inflammation. RESULTS Compared to the HLI group, malondialdehyde and total oxidant status levels in lung tissue were notably reduced in the HLI + MOL group. Furthermore, mean superoxide dismutase, glutathione peroxidase, and glutathione activities/levels in lung tissue were significantly higher in the HLI + MOL group as compared to the HLI group. Tumor necrosis factor-α and interleukin-1β elevations associated with hyperoxia were significantly reduced following MOL treatment. Median histopathological damage and mean alveolar macrophage numbers were found to be higher in the HLI and HLI + MOL groups when compared to the Control and Control+MOL groups. Both values were increased in the HLI group when compared to the HLI + MOL group. CONCLUSIONS Our research is the first to demonstrate that bronchopulmonary dysplasia may be prevented through the protective characteristics of MOL, an anti-inflammatory, anti-oxidant, and anti-apoptotic drug. IMPACT Molsidomine prophylaxis significantly decreased the level of oxidative stress markers. Molsidomine administration restored the activities of antioxidant enzymes. Molsidomine prophylaxis significantly reduced the levels of inflammatory cytokines. Molsidomine may provide a new and promising therapy for BPD in the future. Molsidomine prophylaxis decreased lung damage and macrophage infiltration in the tissue.

Abstract
Peptides are one of the leading groups of compounds that have been the subject of a great deal of biological research and still continue to attract researchers' attention. In this study, a series of tripeptides based on tyrosine amino acids were synthesized by the triazine method. The cytotoxicity properties of all compounds against human cancer cell lines (MCF-7), ovarian (A2780), prostate (PC-3), and colon cancer cell lines (Caco-2) were determined by the 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide assay method, and % cell viability and logIC50 values of the compounds were calculated. Significant decreases in cell viability were observed in all cells (p < 0.05). The comet assay method was used to understand that the compounds that showed a significant decrease in cell viability had this effect through DNA damage. Most of the compounds exhibited cytotoxicity by DNA damage mechanism. Besides, their interactions between investigated molecule groups with PDB ID: 3VHE, 3C0R, 2ZCL, and 2HQ6 target proteins corresponding to cancer cell lines, respectively, were investigated by docking studies. Finally, molecules with high biological activity against biological receptors were determined by ADME analysis.

Abstract
BACKGROUND The presence of Transient Receptor Potential Vanilloid 1 (TRPV1) channels was detected in many regions of the human and rat brain, including the cortex and hippocampus. TRPV1 channels have functions such as the modulation of synaptic transmission and plasticity and the regulation of cognitive functions. Previous studies conducted with TRPV1 agonists and antagonists show that this channel is associated with the neurodegenerative process. In the present study, the purpose was to investigate the effects of capsaicin, which is a TRPV1 agonist, and capsazepine, a TRPV1 antagonist, in the Alzheimer's Disease (AD) model that was induced by intracerebroventricular (ICV) administration of okadaic acid (OKA). METHODS The AD-like experimental model was created with bilateral ICV OKA injection. Intraperitoneal capsaicin and capsazepine injections were administered to the treatment groups for 13 days and histological and immunohistochemical examinations were performed from the cortex and hippocampal CA3 regions of the brain. The Morris Water Maze Test was used for spatial memory measurement. RESULTS ICV OKA administration increased the levels of caspase-3, phosphorylated-tau-(ser396), Aβ, TNF-α, and IL1-β, from the cortex and hippocampal CA3 regions of the brain and decreased the phosphorylated-Glycogen synthase kinase-3 beta-(ser9) levels. In addition, the OKA administration corrupted the spatial memory. The TRPV1 agonist capsaicin reversed the pathological changes induced by ICV OKA administration, but not the TRPV1 antagonist capsazepine. CONCLUSIONS It was found in the study that the administration of the TRPV1 agonist capsaicin reduced neurodegeneration, neuroinflammation, and deterioration in spatial memory in the AD model induced by OKA.

Abstract
This study was conducted to determine the possible effects of intracerebroventricular MOTS-c infusion on thyroid hormones and uncoupling proteins (UCPs) in rats. Forty male Wistar Albino rats were divided into 4 groups with 10 animals in each group: control, sham, 10 and 100 µM MOTS-c. Hypothalamus, blood, muscle, adipose tissues samples were collected for thyrotropin-releasing hormone (TRH), UCP1 and UCP3 levels were determined by the RT-PCR and western blot analysis. Serum thyroid hormone levels were determined by the ELISA assays. MOTS-c infusion was found to increase food consumption but it did not cause any changes in the body weight. MOTS-c decreased serum TSH, T3, and T4 hormone levels. On the other hand, it was also found that MOTS-c administration increased UCP1 and UCP3 levels in peripheral tissues. The findings obtained in the study show that central MOTS-c infusion is a directly effective agent in energy metabolism.

Abstract
In this study, we aimed to synthesize new peptide-substituted cyclotriphosphazenes from a series of tyrosine-based peptides and dioxyphenyl-substituted spirocyclotriphosphazenes, and to evaluate their in vitro cytotoxicity and genotoxicity activities. Genotoxicity studies were conducted to understand whether the cytotoxic compounds cause cell death through DNA damage. The structures of the novel series of phosphazenes were characterized by FT-IR, elemental analysis, MS, 1D (31P, 1H, and 13C-APT NMR), and 2D (HETCOR) NMR spectroscopic techniques. In vitro cytotoxic activities were carried out against human breast (MCF-7), ovarian (A2780), prostate (PC-3), colon (Caco-2) cancer cell lines and human normal epithelial cell line (MCF-10A) at different concentrations by using an MTT assay. The compounds showed considerable reductions in cell viability against all human cancer cell lines. Especially, the compounds exhibited notable effects in A2780 cell lines (p < 0.05). The IC50 values of the compounds in the A2780 cell line were calculated to be 1.914 µM for TG, 20.21 µM for TV, 20.45 µM for TA, 4.643 µM for TP, 5.615 µM for BTG, 1.047 µM for BTV, 27.02 µM for BTA, 0.7734 µM for BTP, 21.5 µM for DTG, 1.65 µM for DTV, 2.89 µM for DTA and 4.599 µM for DTP. DNA damage studies of the compounds were conducted by the comet assay method using tail length, tail density, olive tail moment, head length, and head density parameters, and the results showed that the cell death occurred through DNA damage mechanism. In a nutshell, these compounds show promising cytotoxic effects and can be considered powerful candidate molecules for pharmaceutical applications.

Abstract
BACKGROUND The protective effects of mitochondrial open reading frame of the 12S rRNA-c (MOTS-C) on cardiovascular diseases have been shown in numerous studies. However, there is little documentation of the relationship between MOTS-C and coronary blood flow in ST-segment elevation myocardial infarction (STEMI). OBJECTIVE We aimed to investigate the role of MOTS-C, which is known to have cytoprotective properties in the pathogenesis of the no-reflow phenomenon, by comparing the coronary flow rate and MOTS-C levels in patients with STEMI submitted to primary PCI. METHODS 52 patients with STEMI and 42 patients without stenosis >50% in the coronary arteries were included in the study. The STEMI group was divided into two groups according to post-PCI TIMI (Thrombolysis In Myocardial Infarction) flow grade:(i) No-reflow: grade 0, 1, and 2 and (ii) grade 3(angiographic success). A p value of <0.05 was considered significant. RESULTS MOTS-C levels were significantly lower in the STEMI group compared to the control group (91.9 ± 8.9 pg/mL vs. 171.8±12.5 pg/mL, p<0.001). In addition, the Receiver Operating Characteristics (ROC) curve analysis indicated that serum MOTS-C levels had a diagnostic value in predicting no-reflow (Area Under the ROC curve [AUC]:0.95, 95% CI:0.856-0.993, p<0.001). A MOTS-C ≥84.15 pg/mL measured at admission was shown to have 95.3% sensitivity and 88.9% specificity in predicting no-reflow. CONCLUSION MOTS-C is a strong and independent predictor of no-reflow and in-hospital MACE in patients with STEMI. It was also noted that low MOTS-C levels may be an important prognostic marker of and may have a role in the pathogenesis of STEMI.

Abstract
OBJECTIVE The fibrosis can be detected using non-invasive methods including prolidase activity, proline levels and galectin-3 (GAL-3) detection in the serum. The aim of this study was to investigate the liver fibrosis through non-invasive methods in chronic hepatitis B patients. PATIENTS AND METHODS This prospective case control study includes 56 patients with Chronic Active Hepatitis B (CAHB), 57 patients with Inactive Hepatitis B (IHB), and 60 healthy matched control subjects. The first group included the CAHB [hepatitis B surface antigen (HBsAg): positive; HBV DNA >2,000 IU/mL; normal or high alanine aminotransferase (ALT) value] undergo a liver biopsy, while the second group included the IHB (HBsAg: positive; HBV DNA: negative; normal ALT value). The third group comprised the healthy controls. Serum prolidase enzyme activities (SPEA), proline and galectin-3 levels were measured for each group. RESULTS Patients with CAHB had significantly higher SPEA levels (1,004.3±186.8 IU/L) than did the controls (196.5±306 IU/L) (p<0.001). Significantly higher serum GAL-3 levels were found in the CHB group compared with HBV carrier and the control groups (27.4±32.2 ng/mL, 6.5±13.4 ng/mL, 3.1±5.7 ng/mL, respectively, p<0.001). The relationship between serum prolidase activity, hidroxiprolyne and fibrosis (p<0.05). There were no significant differences in ALT levels between inactive HBV carriers and the control groups (p>0.05). CONCLUSIONS We suppose that hidroxiprolyne levels and prolidase enzyme activity might be an indicator as a marker for fibrosis in CAHB and the evaluation of response to treatment.

Abstract
OBJECTIVE Atherosclerosis plays a major role in the development of coronary artery disease (CAD). It has been shown that mitochondrial open-reading-frame of the twelve S rRNA-c (MOTS-c), a mitochondrial-derived peptide, has preventive effects on atherosclerosis. The aim of this study was to determine the relationship between MOTS-c levels and CAD presence and severity using SYNTAX score (SS) in patients with stable angina pectoris. PATIENTS AND METHODS Ninety-two consecutive patients with stable coronary artery disease (CAD+) and ninety-two consecutive patients with normal coronary artery (CAD-) were included. Presence and severity of coronary artery disease were determined using the SS. RESULTS We observed that the MOTS-c levels was lower in the CAD group (111±13 vs. 161±23, p<0.001). The MOTS-c levels were also found to be significant independent predictors for CAD in multiple regression analysis (p<0.001). A MOTS-c levels ≥130.9 had 80.3% sensitivity and 73.2% specificity (area under the curve [AUC]: 0.858, 95% CI: 0.895-0.999, p<0.001) for predicting CAD. CONCLUSIONS The authors revealed that there is a strong correlation between MOTS-c levels and CAD. Therefore, MOTS-c may help identify patients with CAD, thus allowing for early preventive treatment.

Abstract
Amino acid conjugates are described by the reaction of amino acids with bioactive organic groups such as vitamins, hormones, flavonoids, steroids, and sugars. In this study, 12 new conjugates were synthesized by reaction of cinnamic acid derivatives with various amino acids. Cytotoxic studies against four different human cancer cells (MCF7, PC-3, Caco-2, and A2780) were carried out by MTT assay method at five different concentrations. The structure-activity relationships based on the cell viability rates were evaluated. To compare the anticancer activities of the compounds using computational chemistry methods, they were docked against A2780 human ovarian cancer, Michigan Cancer Foundation-7 (MCF7), human prostate cancer (PC-3) and human colon epidermal adenocarcinoma (Caco-2) cell lines and compared with the standard 5-Fluorouracil. The results indicate that the efficacy of cinnamic acid derivatives increases with the presence of amino acids. Comet assay was conducted to understand whether the cell deaths occur through DNA damage mechanism and the results exhibit that the changes in the specified parameters were statistically significant (P<0.05). Our study demonstrated that the compounds cause cell death through the formation of DNA damage mechanism.

Abstract
OBJECTIVE There is little evidence related to the effects of the Omicron severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant on pregnancy outcomes, particularly in unvaccinated women. This study aimed to compare pregnancy outcomes of unvaccinated women infected with SARS-CoV-2 during the pre-Delta, Delta and Omicron waves. METHODS This was a retrospective cohort study conducted at two tertiary care facilities: Sancaktepe Training and Research Hospital, Istanbul, Turkey, and St George's University Hospitals NHS Foundation Trust, London, UK. Included were women who tested positive for SARS-CoV-2 by real-time reverse-transcription polymerase chain reaction (RT-PCR) during pregnancy, between 1 April 2020 and 14 February 2022. The cohort was divided into three periods according to the date of their positive RT-PCR test: (i) pre-Delta (1 April 2020 to 8 June 2021 in Turkey, and 1 April 2020 to 31 July 2021 in the UK), (ii) Delta (9 June 2021 to 27 December 2021 in Turkey, and 1 August 2021 to 27 December 2021 in the UK) and (iii) Omicron (after 27 December 2021 in both Turkey and the UK). Baseline data collected included maternal age, parity, body mass index, gestational age at diagnosis and comorbidities. The primary outcome was the need for oxygen supplementation, classified as oxygen support via nasal cannula or breather mask, non-invasive mechanical ventilation with continuous positive airway pressure (CPAP) or high-flow oxygen, mechanical ventilation with intubation, or extracorporeal membrane oxygenation (ECMO). Inferences were made after balancing of confounders, using an evolutionary search algorithm. Selected confounders were maternal age, body mass index and gestational age at diagnosis of infection. RESULTS During the study period, 1286 unvaccinated pregnant women with RT-PCR-proven SARS-CoV-2 infection were identified, comprising 870 cases during the pre-Delta period, 339 during the Delta wave and 77 during the Omicron wave. In the confounder-balanced cohort, infection during the Delta wave vs during the pre-Delta period was associated with increased need for nasal oxygen support (risk ratio (RR), 2.53 (95% CI, 1.75-3.65); P < 0.001), CPAP or high-flow oxygen (RR, 2.50 (95% CI, 1.37-4.56); P = 0.002), mechanical ventilation (RR, 4.20 (95% CI, 1.60-11.0); P = 0.003) and ECMO (RR, 11.0 (95% CI, 1.43-84.7); P = 0.021). The maternal mortality rate was 3.6-fold higher during the Delta wave compared to the pre-Delta period (5.3% vs 1.5%, P = 0.010). Infection during the Omicron wave was associated with a similar need for nasal oxygen support (RR, 0.62 (95% CI, 0.25-1.55); P = 0.251), CPAP or high-flow oxygen (RR, 1.07 (95% CI, 0.36-3.12); P = 0.906) and mechanical ventilation (RR, 0.44 (95% CI, 0.06-3.45); P = 0.438) with that in the pre-Delta period. The maternal mortality rate was similar during the Omicron wave and the pre-Delta period (1.3% vs 1.3%, P = 0.999). The need for nasal oxygen support during the Omicron wave was significantly lower compared to the Delta wave (RR, 0.26 (95% CI, 0.11-0.64); P = 0.003). Perinatal outcomes were available for a subset of the confounder-balanced cohort. Preterm birth before 34 weeks' gestation was significantly increased during the Delta wave compared with the pre-Delta period (15.4% vs 4.9%, P < 0.001). CONCLUSIONS Among unvaccinated pregnant women, SARS-CoV-2 infection during the Delta wave, in comparison to the pre-Delta period, was associated with increased requirement for oxygen support (including ECMO) and higher maternal mortality. Disease severity and pregnancy complications were similar between the Omicron wave and pre-Delta period. SARS-CoV-2 infection of unvaccinated pregnant women carries considerable risks of morbidity and mortality regardless of variant, and vaccination remains key. Miscommunication of the risks of Omicron infection may impact adversely vaccination uptake among pregnant women, who are at increased risk of complications related to SARS-CoV-2. © 2022 The Authors.

Abstract
A series of chalcone compounds (2-11) were designed and synthesized to determine their cytotoxic effects. The structures of 2-11 were fully characterized by their physical and spectral data. The in vitro cytotoxic effects of 2-11 were evaluated against human ovarian cancer (A2780), breast cancer (MCF-7) and prostate cancer (PC-3 and LNCaP) cell lines. The activity potentials of compounds were further evaluated through molecular docking studies with AutoDock4 and Vina softwares. All the compounds (except compound 5) showed significant cytotoxic effects at high doses in all cancer cell lines. Among all the compounds studied, one compound i.e. compound 2 demonstrated dose-dependent activity, particularly against A2780/LNCaP cancer cell lines. The most effective compounds 8, 9, 10 and 11 reduced the cell viability of A2780, MCF-7, PC-3 and LNCaP cells by 50-98%, while other compounds 2, 4 and 7 reduced the cell viability of A2780 cells by 70-90% at concentrations of 50 and 100 µM.

Abstract
Seven novel pyrazole derivatives (4a-g) and four novel starting compounds incorporating substituted pyridine moieties were synthesized successfully. Cell viability assay for the tested compounds was performed, and the inhibitory concentrationlogarithmic 50 (LogIC50 ) values of the compounds were calculated after a 24-h treatment. Four of the examined compounds (3d, 3g, 4f, and 4g) showed comparable cytotoxic activity against CaCo-2 compared to the standard drug docetaxel at 0.1 and 1 μM concentrations. Although the LogIC50 of docetaxel was -0.678 μM for CaCo-2 cells at 24 h, the LogIC50 values of compounds were -0.794, -0.567, -0.657, and -0.498 μM, respectively. Five of the compounds (2d, 2g, 3d, 3g, and 4e) showed comparable cytotoxic activity against MCF-7 at 0.1 μM concentration compared to docetaxel (p < 0.05). Docking studies revealed the compounds have a good affinity to the active site of the human topoisomerase II β enzyme. The antioxidant capacities of all compounds were determined using both 1,1-diphenyl-2-picrylhydrazyl and metal chelation methods. Although the compounds did not show significant antioxidant activity, relatively effective are compounds 3c, 3d, and 3g, which are hydrazine derivatives with approximately 50% antioxidant activity of standard antioxidants at concentrations of 62.5 and 125 μg/ml.

Abstract
Saxagliptin is an effective and selective dipeptidyl peptidase-4 (DPP-4) inhibitor. This study was designed to determine possible protective effects of saxagliptin against damage caused by renal ischaemia/reperfusion (I/R) in rats. In this study, 40 rats were divided into 4 groups (n = 10 for each). Group 1 (Control), Group 2 (I/R) in both kidneys ischaemia of 45 min was performed, and then reperfusion was applied for 24 h. Saxagliptin (Group 3: 2 mg/kg and Group 4: 10 mg/kg) was administered by oral gavage to the animals in treatment groups, before the I/R. Saxagliptin decreased the markers (BUN, Cre, NGAL, KIM-1 and IL-18) of acute renal damage in blood and kidney tissue. Saxagliptin provided increase in antioxidant enzyme levels and decrease in MDA and apoptosis. Histological results showed that the administration of saxagliptin exhibited a protective effect against renal damage caused by I/R. These results indicates that saxagliptin provide protection against kidney injury caused by I/R.

Abstract
Introduction Amisulpride is an atypical antipsychotic. Rabbit syndrome(RS) may be seen after antipsychotics use a few days or long‐term application. RS occurs after more frequent typical antipsychotics and also in rare cases atypical antipsychotics.Its characterized by the involuntary rhythmic movements of the lips however involves no tongue movements. Objectives Case report and reflection on its etiology Methods Case report and literature review Results A 28-year-old female with a diagnosis of schizophrenia applied with the complaints and symptoms of withdrawal, do not want to leave the house, physical anergy and avolition that started after stopped taking her medications. She was admitted to the psychiatry service and amisulpride treatment was started and was gradually increased to 800 mg/day. After 30 days of hospitalization, the patient was discharged with mild recovery. 14 days after the discharge, because of the abnormal involuntary movements in mouth, the patient applied. In clinical examination without tounge involvement, rhythmic motions were observed in the lips and jaw.Neurological examination, labrotory tests and cranial screening were all normal. She was evaluated by a private psychiatrist and was diagnosed with RS. Amisulpride treatment changed to olanzapine treatment with 15 mg/day. After two months, RS spontaneously regressed. Conclusions The resolution of the involuntary movements following discontinuation of amisulpride in our case, supported the diagnosis of RS. Although the mechanism by which RS emerges as a side‐effect of amisulpride is not fully understood, the drug’s high affinity for and selective binding to dopaminergic D2 and D3 receptors are thought to be responsible for this involuntary motion disorder.

Abstract
Introduction Venlafaxine is a serotonin-norepinephrine reuptake inhibitor and its extensive use for major depressive disorder and anxiety disorders. Although it has been reported that venlafaxine may have various side effects, as far as we know, spontaneous ejaculation(SE) has not been reported yet. Objectives We aim to describe this clinical case with venlafaxine-induced SE and to discuss the possible etiological factors. Methods Case report and literature review. Results A 53-year-old male with generalized anxiety disorder was initiated venlafaxine treatment with 75 mg/day. After two months patient’s complaints partially regressed and the dose of venlafaxine treatment was increased to 150 mg/day. 10 days after the dose increase, the patient applied with the complaint of SE 2-3 times a day. No urological etiology was found. During outpatient follow-ups, after the 5 days from reducing the daily dose to 75 mg/day, SE complaint completely regressed. After following couple of months, the patient by himself, increased the dose of venlafaxine to 150 mg/day without consulting a psychiatrist. Then SE recurred approximately 15 days later. Venlafaxine treatment dose was reduced again to 75 mg/day and urological complaints spontaneously regressed. Conclusions SE, a rare sexual side effect, represents ejaculation that occurs involuntarily and in the absence of any sexual stimuli. The possible mechanism of SE, detected as a side effect in our case, may be that increased adrenergic activity reduces ejaculatory latency and triggers spontaneous ejaculation. Antidepressant-associated sexual dysfunction could be a dose-dependent adverse event. Therefore, reducing the dosage of the treatment to a minimum effective dose could be an option.

Abstract
Synthesis of five different new compounds (1-5) were carried out. Their structures were characterized by spectroscopic methods such as Fourier transform infrared, Proton nuclear magnetic resonance, Carbon-13 nuclear magnetic resonance and Elemental analysis. Cytotoxic activities of five new sulfonamide based-Schiff base compounds were determined by MTT assay using A-2780 (human ovarian cancer) and MCF-7 (breast cancer) cell lines. LogIC50 values of the sulfonamide derivates compounds were calculated by Graphpad Prism 12 programme after a 24-hour treatment for A2780 and MCF-7 cells. Comet assay experiments were performed to determine DNA damage using LogIC50 concentrations of all compounds in A2780 and MCF-7 cells. All compounds significantly reduced A2780 and MCF-7 cell viability compared to control groups (p < 0.05). In addition, all compounds caused DNA damage in A2780 and MCF-7 cells (p < 0.05). These results show that the synthesized compounds exhibit cytotoxic effects against cancer cells and that the cause of cell death is due to DNA damage.Communicated by Ramaswamy H. Sarma.

Abstract
AIM Inflammation and oxidate stress are significant factors in the pathogenesis of bronchopulmonary dysplasia (BPD). The aim of this study is to investigate the efficacy of apocynin (APO), an anti-inflammatory, antioxidant, and antiapoptotic drug, in the prophylaxis of neonatal hyperoxic lung injury. METHOD This experimental study included 40 neonatal rats divided into the control, APO, BPD, and BPD + APO groups. The control and APO groups were kept in a normal room environment, while the BPD and BPD + APO groups were kept in a hyperoxic environment. The rats in the APO and BPD + APO groups were administered intraperitoneal APO, while the control and BPD rats were administered ordinary saline. At the end of the trial, lung tissue was evaluated with respect to the degree of histopathological injury, apoptosis, oxidant and antioxidant capacity, and severity of inflammation. RESULT The BPD and BPD + APO groups exhibited higher mean histopathological injury and alveolar macrophage scores compared to the control and APO groups. Both scores were lower in the BPD + APO group in comparison to the BPD group. The BPD + APO group had a significantly lower average of TUNEL positive cells than the BPD group. The lung tissue examination indicated significantly higher levels of mean malondialdehyde (MDA), total oxidant status (TOS), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β) in the BPD group compared to the control and APO groups. While the TNF-α and IL-1β levels of the BPD + APO group were similar to that of the control group, the MDA and TOS levels were higher compared to the controls and lower compared to the BPD group. The BPD group demonstrated significantly lower levels/activities of mean total antioxidant status, glutathione reductase, superoxide dismutase, glutathione peroxidase in comparison to the control and APO groups. While the mean antioxidant enzyme activity of the BPD + APO group was lower than the control group, it was significantly higher compared to the BPD group. CONCLUSION This is the first study in the literature to reveal through an experimental neonatal hyperoxic lung injury that APO, an anti-inflammatory, antioxidant, and antiapoptotic drug, exhibits protective properties against the development of BPD.

Abstract
Asprosin, a protein-based secretary product of white adipose tissue, stimulates appetite hepatic glucose production. It crosses blood-brain barrier and stimulates appetite center and causes sperm chemotaxis but exact role of this endogenous agent is not completely known. This study was conducted to investigate possible effects of central asprosin infusion on the hormones involved in the hypothalamic-pituitary-testicular (HPT) axis and sperm cells. Spraque Dawley male rats were divided into four groups; control, sham, low asprosin (34) and high asprosin (68 nM) groups, (n = 10 for each group). Control group remain intact while a brain infusion kit was placed in the lateral ventricles of the rats in the sham group (artificial cerebrospinal fluid) and asprosin (34 and 68 nM) was infused for 14 days. At the end of the experiment, the hypothalamus, blood, and epididymis tissues of the rats were collected. Gonadotropin-releasing hormone (GnRH) mRNA and tissue protein levels were determined in the hypothalamus tissue by RT-PCR and Western Blot methods. Serum luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone levels were examined using the ELISA method from blood samples and sperm cells were examined in the epididymis tissue. GnRH mRNA and protein expressions of asprosin administered groups were higher than control and sham groups (p < 0.05). Asprosin infusion was also found to increase serum FSH, LH, and testosterone levels (p < 0.05). In addition, sperm density, motility, and progressive movement were observed to increase in asprosin administered groups (p < 0.05). This study suggests that central asprosin stimulate the HPT axis and also epididymis tissue. Our results implicates potential role for asprosin in male infertility.

Abstract
Salusin-β (Sal-β), which originates from preprosalusin, is a multifunctional hormone with a peptide structure. Sal-β exists in the hypothalamus and can stimulate the pituitary gland. The present study was conducted to determine the effects of Sal-β on hormones that play roles in the male reproductive system. Forty male Wistar Albino rats were used in the study. No infusions were performed on the control group, and infusions were applied to the infusion groups (artificial cerebrospinal fluid to the sham group, 2 and 20 nM Sal-β to the experimental group) through intracerebroventricular infusion for 7 days at 10 μl/hour rate. The animals were decapitated after 7 days of infusion; and the hypothalamus, testicles, and blood tissue samples were collected. The gonadotropin-releasing hormone (GnRH) mRNA levels were determined from the hypothalamus tissues by using the Real Time-PCR Method, and the serum luteinizing hormone (LH), follicle-stimulating hormone (FSH) and testosterone levels were determined using the ELISA method. Also, Hematoxylin-Eosin Staining Method was used for histopathological evaluations in the testicle tissues. As a result, Sal-β infusion increased GnRH mRNA levels in hypothalamus tissues (p < 0.05) besides, serum LH, FSH, and testosterone levels of the rats were higher at significant levels following Sal-β infusion compared to the control and sham group (p < 0.05). In the histological examination of the testicle tissues, Sal-β application was found to decrease the seminiferous tubule diameter and germinal epithelial thickness (p < 0.05). This evidence is the first, indicating that Sal-β, which is administered to male rats with central infusion, stimulates hypothalamus and pituitary tissues, and causes increased secretion of male reproductive hormones.

Abstract
Nine novel hydrazone derivatives (4a-i) incorporating pyridine and isatin moieties were synthesized through one-pot, four-component heterocyclic condensation reactions. The structures of all new compounds (2a-e, 3a, 3c-e, and 4a-e) were identified by 1 H nuclear magnetic resonance (NMR), 13 C NMR, and Fourier-transform infrared spectroscopic techniques and elemental analysis. Cell viability assays for the tested hydrazone derivatives were performed and the log IC50 values of the compounds were calculated after a 24-h treatment. All hydrazide derivatives tested showed a promising antitumor activity against A-2780 cells as compared with the standard drug docetaxel with a log IC50 value of 0.2200 μM (p < .05). Seven of the examined compounds (4b-e, 4g-i) showed high cytotoxic activity against A-2780 cells as compared with the standard drug docetaxel. Whereas the log IC50 of docetaxel was 0.2200 μM for A-2780 cells at 24 h, the IC50 values of these compounds were -0.4987, -0.4044, -0.8138, -0.3868, -0.6954, -0.4751, and 0.1809 μM, respectively. Three of the compounds, 4b, 4d, and 4i, showed high cytotoxic activity against MCF-7 cells as compared with docetaxel (p < .05). Whereas the log IC50 of docetaxel was 0.2400 μM for MCF-7 cells at 24 h, the log IC50 values of compounds 4b, 4d, and 4i were -0.1293, -0.1700, and 0.2459 μM, respectively.

Abstract
The hexachlorocyclotriphosphaze compound (N3P3Cl6, HCCP) was reacted with excess (E)-(1-(4'-oxyphenyl)-3-(substituted-phenyl)prop-2-en-1-ones (2-11) to produce hexakis[(1-(4-oxyphenyl)-3-(substituted-phenyl)prop-2-en-1-one)]cyclotriphosphazenes (CP 2-11). The structures of products (CP 2-11) were confirmed using elemental analysis, FT-IR, MS spectral analysis as well as 31P, 1H and 13C-APT NMR techniques and their thermal properties determined by TGA and DSC techniques. The HOMO-LUMO energy gap and chemical reactivity identifiers were calculated and HOMO and LUMO images were viewed. According to the calculations, all the chemical potential values of CP 2-11 are negative and it shown that the molecules are stable. The in vitro cytotoxic of CP 2-11 investigated and their activity potentials were evaluated by molecular docking studies with Autodock Vina softwares. CP 2-11 compounds were found to demonstrate cytotoxic activity against human cancer cell lines (A2780, LNCaP and PC-3). The CP 2-11 compounds reduced the cell viability against all cancer cell lines in the range 36%-90% especially. The results showed that these compounds are powerful candidate molecules for pharmaceutical applications.

Abstract
Aims: 17α-hydroxylase deficiency is a rare form of congenital adrenal hyperplasia (CAH) which is inherited autosomal recessive. It occurs result of a mutations in gene cytochrome (CYP)17A1, which encodes both 17α-hydroxylase and 17,20-lyase enzymes. The main clinical findings of the disease are delayed puberty, primary amenorrhea in females, and disorders of sex development (DSD) in males. Also, hypertension and hypokalemia can be seen in both sexes. In this paper, we describe the clinical and genetic changes of two patients with 46,XY and 46,XX karyotypes from two different families who were diagnosed with complete 17α-hydroxylase enzyme deficiency.Methods: In this study various methods including clinical, hormonal, radiological and genetic analyzes were used. Blood samples were obtained for genetic tests. Genomic DNA was extracted from peripheral blood leukocytes, and coding sequence abnormalities of the CYP17 gene were assessed by polymerase chain reaction and direct sequencing analysis.Results: 17α-hydroxylase deficiency was diagnosed in 2 patients with 46,XX and 46,XY karyotype who presented with hypertension and delayed puberty. The pQ80 * (c.238C > T) mutation detected in both cases was evaluated as a novel variant.

Abstract
1,2,4-Triazoles are used as antifungal, antibacterial, antimicrobial, and antioxidant against some oxidative radical species. Recently, many 1,2,4-triazoles continue to be synthesized. In this study, the effect of the 1,2,4-triazole derivatives on human colon cancer (HT29) was investigated in vitro and in vivo in rats. MTT test was applied to in in vitro experiments. For in vivo study, rats were divided into seven groups as follows: Control group (negative control), azoxymethane (AOM), AOM + cisplatin 15, AOM + L1, AOM + L2, AOM + L3, and AOM + L4. To create colon cancer, the AOM injection was injected subcutaneously at a dose of 15 mg/kg, three times (once weekly). The in vivo studies were completed at 28 weeks. It was found that the 1,2,4-triazole derivatives reduced the cell viability (P < 0.05). In all animals in the experimental groups, mild dysplasia was detected in 100% of the colon mucosal epithelium. Severe dysplasia and adenocarcinoma were observed in L1 groups. As a result, this study determined that the 1,2,4-triazole derivatives exhibit antitumor activity.

Abstract
BACKGROUND Infection with the influenza A virus can cause severe disease and mortality. The effect of the different subtypes of influenza on morbidity and mortality is not yet known in Turkey. The aim of this study was to describe the predictors of fatality related to influenza A infection among hospitalized patients in Istanbul during the 2015-2016 influenza season, and to detail the differences between infections caused by H3N2 and H1N1. METHODS This was a multicenter study performed by the Istanbul Respiratory Infections Study Group of The Turkish Society of Clinical Microbiology and Infectious Diseases (KLİMİK), among patients hospitalized for influenza in Istanbul during the 2015-2016 influenza season. RESULTS A total of 222 patients hospitalized with laboratory-confirmed influenza during the 2015-2016 season were included in the study, of whom 25 (11.2%) died. The fatality rate was significantly higher among patients older than 65 years of age and those with chronic heart and kidney diseases (p<0.001), chronic neurological diseases (p=0.009), and malignancies (p=0.021). Thrombocyte counts were lower in those who died than in those who survived (p<0.004). The median alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, creatinine phosphokinase, and C-reactive protein levels were higher among fatal cases. In the multivariate analysis for the prediction of fatality, being >65years old (odds ratio (OR) 6.9, 95% confidence interval (CI) 2.07-23.08, p=0.002), being infected with influenza A(H3N2) (OR 4.2, 95% CI 1.27-14.38, p=0.019), and a 1-day delay in antiviral use (OR 1.28, 95% CI 1.01-1.63, p=0.036) were found to be associated with an increased likelihood of fatality. CONCLUSIONS The case fatality rate of influenza A(H3N2) was significantly higher than that of influenza A(H1N1). Detection of the infection, allowing the opportunity for the early use of antiviral agents, was found to be important for the prevention of fatality. The vaccination should be prioritized for at-risk groups.

Abstract
Persistent Müllerian Duct syndrome (PMDS) develops due to deficiency of anti-Müllerian hormone (AMH) or insensitivity of target organs to AMH in individuals with 46,XY karyotype. PMDS is characterized by normal male phenotype of external genitals, associated with persistence of Müllerian structures. This report includes the presentation of a 2.5 year old male patient due to bilateral undescended testis. His karyotype was 46,XY. The increase in testosterone following human chorionic gonadotropin stimulation test was normal. The patient was referred to our clinic after uterine, fallopian tube and vaginal remnants were recognized during the orchiopexy surgery. The family reported that the eight year old elder brother of the patient was operated on for right inguinal hernia and left undescended testis at the age of one year. A right transverse testicular ectopia was found in the elder brother. Both cases had normal AMH levels. AMHR2 gene was analyzed and a homozygous NM_020547.3:c.233-1G>A mutation was found that was not identified previously. In conclusion, we determined a novel mutation in the AMHR2 gene that was identified for the first time. This presented with different phenotypes in two siblings.

Abstract
The aim of this study was to evaluate the impact of intracerebroventricular chronic fibroblast growth factor 21 (FGF21) infusion on hypothalamic-pituitary-thyroid (HPT) axis, energy metabolism, food intake and body weight. Thirty male Wistar albino rats were used and divided into three groups including control, sham (vehicle) and FGF21 infused groups (n = 10). Intracerebroventricularly, FGF21 and vehicle groups were infused for 7 days with FGF21 (0.72 µg/day) and artificial cerebrospinal fluid, respectively. During the experimental period, changes in food intake and body weight were recorded daily. Serum thyroid stimulating hormone (TSH), Triiodothyronine (T3) and thyroxine (T4) levels were measured using ELISA. TRH and uncoupling protein 1 (UCP1) gene expressions were analyzed by using RT-PCR in hypothalamus and adipose tissues, respectively. Chronic infusion of FGF21 significantly increased serum TSH (p < 0.05), T3 (p < 0.05) and T4 (p < 0.001) levels. Additionally, hypothalamic TRH (p < 0.05) and UCP1 gene expressions (p < 0.05) in white adipose tissue were found to be higher than in the vehicle and control groups. While FGF21 infusion did not cause a significant change in food consumption, it caused a reduction in the body weight of rats (p < 0.05). Our findings indicate that FGF21 may have an effect on energy metabolism via the HPT axis.
