Abstract
OBJECTIVE Infertility impacts a substantial number of couples worldwide, and about 50% of cases are linked to male factors. The analysis of seminal fluid composition can improve diagnostic accuracy and offer deeper insights into the pathophysiology of male factor infertility. This study seeks to identify novel markers for diagnosing and treating male infertility by comparing organic acid profiles in the seminal fluid of individuals with normospermia, oligospermia, and azoospermia. PATIENTS AND METHODS Semen samples were collected from men with normospermia, oligospermia, and azoospermia. The organic acid profile in the seminal fluid was analyzed using liquid chromatography-mass spectrometry/mass spectrometry (LC/MS-MS). Data analysis was performed using SPSS and MetaboAnalyst. RESULTS The study revealed significant differences in metabolite levels among normospermic, oligospermic, and azoospermic individuals. In groups with oligospermia, there were significant decreases in the levels of 2-OH-Isovaleric Acid, 3-Methyl-2-Oxovaleric Acid, Ethyl-Malonic Acid, Citric Acid, Oxoproline, Malic Acid, N-Acetyl-Aspartic Acid, Suberic Acid, Glutaconic Acid, and Succinic Acid. Similarly, individuals with azoospermia exhibited a notable reduction in the levels of Citric Acid, Malic Acid, and Suberic Acid. Furthermore, according to the Variable Importance in the Projection (VIP) score analysis, Ethyl-Malonic Acid, Glycolic Acid, and 3-Methyl-2-Oxovaleric Acid were identified as crucial factors for diagnosis and potential treatment strategies. CONCLUSIONS The data obtained from the study highlights the significant potential of metabolites in assessing infertility and gaining a more in-depth understanding of the underlying pathological mechanisms.

Abstract
OBJECTIVE The World Health Organization recognizes infertility as a public health issue. An estimated 48.5 million couples worldwide grapple with infertility. Infertility and spermatogenesis dysfunction arise from diverse genetic factors, including single-gene mutations and chromosomal abnormalities. Current research continues to explore other potential causes of infertility, leveraging both proteomic and metabolomic analyses. The primary aim of this study is to underscore the significance of investigating male infertility from a metabolomic perspective. PATIENTS AND METHODS This study aimed to identify new markers for diagnosing and treating male infertility by examining the carnitine profiles in seminal fluids of individuals diagnosed with the normospermic group, oligospermic group, and azospermic group, employing the LC/MS-MS method. RESULTS The first three L-carnitines C2 (Acetylcarnitine), C8:1 (Octenoylcarnitine), and C16:1 (Palmitoleylcarnitine), emerged as potential novel markers for diagnosis and treatment. CONCLUSIONS Based on these findings, we posit that the results obtained in this study will aid in diagnosing, treating, and monitoring systemic diseases, and provide a foundation for more comprehensive future molecular studies aimed at enhancing prevention and treatment strategies for infertility.

Abstract
BACKGROUND The renin-angiotensin-aldosterone system was shown to be activated in severe COVID-19 infection. We aimed to investigate the relationship between angiotensin converting enzyme (ACE) levels, ACE gene polymorphism, type 2 diabetes (T2DM), and hypertension (HT) and the prognosis of COVID-19 infection. METHODS This cross-sectional study analyzed the clinical features of adult patients with SARS-CoV-2 infection. ACE gene analysis and ACE level measurements were performed. The patients were grouped according to ACE gene polymorphism (DD, ID or II), disease severity (mild, moderate, or severe), and the use of dipeptidyl peptidase-4 enzyme inhibitor (DPP4i), ACE-inhibitor (ACEi) or angiotensin receptor blocker (ARB). Intensive care unit (ICU) admissions and mortality were also recorded. RESULTS A total of 266 patients were enrolled. Gene analysis detected DD polymorphism in the ACE 1 gene in 32.7% (n = 87), ID in 51.5% (n = 137), and II in 15.8% (n = 42) of the patients. ACE gene polymorphisms were not associated with disease severity, ICU admission, or mortality. ACE levels were higher in patients who died (p = 0.004) or were admitted to the ICU (p<0.001) and in those with severe disease compared to cases with mild (p = 0.023) or moderate (p<0.001) disease. HT, T2DM, and ACEi/ARB or DPP4i use were not associated with mortality or ICU admission. ACE levels were similar in patients with or without HT (p = 0.374) and with HT using or not using ACEi/ARB (p = 0.999). They were also similar in patients with and without T2DM (p = 0.062) and in those with and without DPP4i treatment (p = 0.427). ACE level was a weak predictor of mortality but an important predictor of ICU admission. It predicted ICU admission in total (cutoff value >37.092 ng/mL, AUC: 0.775, p<0.001). CONCLUSION Our findings suggest that higher ACE levels, but not ACE gene polymorphism, ACEi/ARB or DPP4i use, were associated with the prognosis of COVID-19 infection. The presence of HT and T2DM and ACEi/ARB or DPP4i use were not associated with mortality or ICU admission.

Abstract
INTRODUCTION After a scorpion sting, patients commonly present to hospitals with pain. Our study sought to compare the analgesic efficacy of IV paracetamol, IV dexketoprofen trometamol, topical lidocaine, and placebo in patients reporting pain after presenting with a history of scorpion sting. METHODS This double-blind, randomized, placebo-controlled study was conducted in the emergency department of a tertiary hospital. Adult patients who presented with the complaint of pain after a scorpion sting and did not have systemic findings were randomly assigned to 1 of the following 4 groups: IV paracetamol, IV dexketoprofen trometamol, topical lidocaine, and placebo. The visual analog scale scores were measured at the time of presentation to the emergency department and at 30 and 60 min to determine the pain intensity. RESULTS The study included 106 patients, of whom 30 were in the paracetamol group, 26 in the dexketoprofen trometamol group, 25 in the topical lidocaine group, and 25 in the placebo group. We did not find a different analgesic effect among the groups in the first 30 min (P=0.185). IV paracetamol, dexketoprofen trometamol, and topical lidocaine did not show different analgesic effects in the first 60 min (P>0.05). IV paracetamol and dexketoprofen trometamol were found to provide a more effective analgesia than the placebo at 60 min (P<0.05). The analgesic effects of topical lidocaine and placebo did not differ (P=0.330). CONCLUSIONS IV paracetamol and IV dexketoprofen trometamol provided analgesia in the first 60 min, similar to topical lidocaine but superior to placebo.

Abstract
PURPOSE Vitamin D deficiency has emerged as another potential risk factor for coronavirus disease (COVID-19) due to the immunomodulatory effects of 25 hydroxyvitamin D [25 (OH)D]. Vitamin D receptor (VDR) gene polymorphisms such as Fok I, Bsm I, Apa I, and Taq I are also associated with different courses of viral infections. This study aimed to evaluate the association between the VDR gene polymorphism at Fok I, Taq I, Bsm I, and Apa I genotypes and the prognosis of COVID-19 in respect to vitamin D deficiency. METHODS Two-hundred ninety-seven patients with COVID-19 were enrolled. Serum 25 (OH)D levels were measured. Four variant regions of the VDR gene, FokI, BsmI, ApaI, and TaqI were determined. RESULTS Eighty-three percent of subjects had vitamin D deficiency, and 40.7% of the whole group had severe deficiency. Median 25 (OH)D level was 11.97 ng/ml. Vitamin D levels were not related to inflammatory markers, disease severity, admission to intensive care unit (ICU), and mortality. While disease severity was related to Fok I Ff genotype, it was Taq TT genotype for ICU admission. Moreover, the ApaI aa genotype was common among the patients who were died. None of the deceased subjects had the Fok I FF genotype. CONCLUSION 25 (OH)D levels were not related to the severity and mortality of COVID-19. VDR gene polymorphisms are independently associated with the severity of COVID-19 and the survival of patients.

Abstract
STUDY OBJECTIVE To determine the analgesic efficacy of TENS treatment in patients with renal colic in the emergency department (ED). METHODS This double-blind, randomized controlled trial was conducted in a tertiary care ED. Patients with a definitive diagnosis of renal colic were assigned (1:1) as randomized to receive the real TENS with frequency 100 Hz, pulse width 200 microseconds, voltage 2 mA, or placebo with sham TENS. Pain intensity was measured using visual analog scales (VAS) at baseline, after 15 and 30th minutes. RESULTS A total of 100 patients were included in the final analysis: 50 patients treated with real TENS and 50 patients treated with sham TENS. VAS scores in both groups were similar at baseline. The mean reduction in VAS score at 15 min was 33.3 ± 17.6 (95% Confidence interval (CI): 28.3 to 38.3) for the real TENS group and 14.9 ± 11.6 (95% CI 11.6 to 18.2) for the sham TENS group (mean difference: 18.4 (95% CI: 12.5 to 24.4, P < 0.0001). The mean reduction in VAS score at 30 min was 63.7 ± 21.1 (95% CI: 57.7 to 69.7) for the real TENS group and 14.9 ± 16.2 (95% CI: 19.5 to 10.3) for the sham TENS group (mean difference: 48.8, 95% CI: 41.4 to 56.3, P < 0.0001). Four patients (8%) in the real TENS group and 24 patients (48%) in the sham TENS group required the rescue medication after 30th minutes. CONCLUSIONS TENS is effective for acute pain treatment in renal colic patients in the ED. TENS therapy could be a treatment option for renal colic.

Abstract
OBJECTIVE To evaluate the association between maternal fructosamine levels at the time of delivery and stillbirth. DESIGN Secondary analysis of a case-control study. SETTING Multicentre study of five geographic catchment areas in the USA. POPULATION All singleton stillbirths with known diabetes status and fructosamine measurement, and representative live birth controls. MAIN OUTCOME MEASURES Fructosamine levels in stillbirths and live births among groups were adjusted for potential confounding factors, including diabetes. Optimal thresholds of fructosamine to discriminate stillbirth and live birth. RESULTS A total of 529 women with a stillbirth and 1499 women with a live birth were included in the analysis. Mean fructosamine levels were significantly higher in women with a stillbirth than in women with a live birth after adjustment (177 ± 3.05 versus 165 ± 2.89 μmol/L, P < 0.001). The difference in fructosamine levels between stillbirths and live births was greater among women with diabetes (194 ± 8.54 versus 162 ± 3.21 μmol/L), compared with women without diabetes (171 ± 2.50 versus 162 ± 2.56 μmol/L). The area under the curve (AUC) for fructosamine level and stillbirth was 0.634 (0.605-0.663) overall, 0.713 (0.624-0.802) with diabetes and 0.625 (0.595-0.656) with no diabetes. CONCLUSIONS Maternal fructosamine levels at the time of delivery were higher in women with stillbirth compared with women with live birth. Differences were substantial in women with diabetes, suggesting a potential benefit of glycaemic control in women with diabetes during pregnancy. The small differences noted in women without diabetes are not likely to justify routine screening in all cases of stillbirth. TWEETABLE ABSTRACT Maternal serum fructosamine levels are higher in women with stillbirth than in women with live birth, especially in women with diabetes.

Abstract
Background Acute gastrointestinal (GI) bleeding is a common cause of hospitalization. There are conflicting results regarding the effectiveness of early endoscopy in patients with upper GI bleeding. Objective The study aimed to determine the benefit of early endoscopy and the epidemiological characteristics of patients presenting to the emergency department with non-variceal acute upper GI bleeding. Methods Patients over 18 years of age who presented to the emergency department with upper GI between 2015 and 2016 and underwent endoscopy were included in the study. The patients were divided into two groups: early endoscopy group (endoscopy within the 24 h) and late endoscopy group (endoscopy after 24 h). Results Of 104 patients, 57.7% were man, and the mean age was 66.27 ± 17.64 years. Of the patients who underwent endoscopy, 80 (76.9%) were in the early endoscopy group. There was no difference in blood transfusion needs (P = 0.388), re-bleeding (P = 0.137), the need for surgery, and mortality rates with regard to the timing of endoscopy. The results of the receiver-operating characteristics curve analysis revealed patients with a GBS ≥ 9 were taken as high-risk, and a prognosis analysis was performed accordingly. However, in patients undergoing early endoscopy, a difference was detected with respect to the length of hospital stay (P = 0.011) and treatment costs (P = 0.030). In the comparison with the admission time (working/non-working h) and variables, there were no significant differences in the length of hospital stay (P = 0.230), transfusion needs (P = 0.348), re-bleeding frequency (P = 0.905), and treatment costs (P = 0.094). Conclusion Endoscopy within 24 h in the setting of acute upper non-variceal GI bleeding is associated with an increase in the length of hospital stay and treatment costs, but is not associated with re-bleeding, transfusion needs, need for surgery, and mortality.

Abstract
OBJECTIVE The aim of the present study was to investigate the neuroprotective effect of ceftriaxone in a rat brain ischemia/reperfusion injury model. METHODS The oxidative stress parameter, malondialdehyde (MDA) levels with or without ceftriaxone treatment in brain ischemia/reperfusion injured rats as well as in controls were measured in serum and brain tissue. Motor examinations of the rats were also performed. One-way Analysis of Variance (ANOVA) test was used for analysis. Duncan's Multiple Range Test was performed in multiple comparisons. p < 0.05 were considered statistically significant. RESULTS: The data of this study showed that ceftriaxone treatment reduced the MDA levels in brain tissues in ischemia/reperfusion injured rats. Moreover, Bederson motor scores were higher in the ceftriaxone treated group as compared to the ischemia group (p = 0.092). CONCLUSION These results suggest that ceftriaxone could be beneficial for the prevention of brain ischemia/reperfusion injury caused by acute arterial occlusion through reducing the tissue MDA level (Tab. 2, Fig. 5, Ref. 24).

Abstract
AIM Cornus mas L is commonly used due to its anti-inflammatory, anti-carcinogenic and anti-oxidant properties. In the study, the effects of C. mas L extract on a solid tumor were examined in the Ehrlich solid tumor model developed in Balb/C type mice. METHODS Ehrlich acid tumor (EAT) cells (1x106 EAT cell) from the stock animal were injected subcutaneously (s.c.) through the nape of the mice. Treatment groups of solid tumor-induced animals received 100 mg/kg and 200 mg/kg of C. mas L extract intraperitoneally (i.p.) for 14 days. RESULTS Tumor volumes and animal weights were found to be statistically significant compared to the control group (p < 0.05). AgNOR staining was performed in tumor tissues. Statistically significant differences were observed between the groups in terms of TAA/NA ratio (p < 0.05). Immunohistochemical and biochemical parameters were also evaluated. An estimation of tumor proliferation of the lung, liver, brain, kidney, testis and tumor antioxidant parameters viz. lipid peroxidation, reduced glutathione (GSH), glutathione S-transferase (GST), superoxide dismutase (SOD) and catalase (CAT) was made. CONCLUSIONS Our study showed that the anti-tumor effect of C. mas L in assisted tumor development with EAT cells, was mediated by the enhancement of oxidative stress with multiple mechanisms (Tab. 6, Fig. 12, Ref. 38).

Abstract
2,4-dinitrotoluene (2,4-DNT) is a priority environmental xenobiotic pollutant which has toxic, mutagenic, and carcinogenic properties. Thus, its biodegradation by applying recent approaches such as taking advantage of plant-bacteria interactions is crucial. In this work, the genes from Burkholderia sp. R34, necessary for 2,4-DNT degradation, were integrated into wild-type Pseudomonas putida (P. putida) KT2440 genome, and this strain, named KT.DNT, was inoculated to soil in in vitro conditions. To estimate the disappearance of 2,4-DNT in contaminated soil, samples were taken from different time intervals, extracted and analyzed using high-performance liquid chromatography (HPLC). Biotransformation of 2,4-DNT increased gradually and the degradation in soil after 14-days of treatment with the bacterium was found to be the 97.1%, indicating that the engineered strain could be a remarkable candidate for in situ bioremediation of 2,4-DNT-contaminated sites. In addition, in vitro interaction of this bacterium with a model plant, Arabidopsis thaliana (A. thaliana), enhanced lateral root and root hair formation together with dry root weight. Moreover, the initial 2,4-DNT concentration was decreased to 68% within 2 h with the plant-associated KT.DNT in liquid culture. Hence, the usage of this bacterium with plants could also be a promising application for the 2,4-DNT biotransformation.

Abstract
OBJECTIVE We aimed to evaluate the diagnostic impact of 18F-FDG PET/CT in staging apocrine breast carcinoma (ABC) and primary breast neuroendocrine carcinoma (PBNEC) and to demonstrate possible alterations of the 18F-FDG uptake in these histopathologic subtypes. In addition, we aimed to compare 18F-FDG PET/CT findings between ABC, PBNEC and invasive ductal carcinoma. MATERIAL AND METHODS A total of 570 patients and 585 breast lesions were retrospectively included in this study. After patients were classified into molecular subtypes according to the histopathological analysis, 18F-FDG PET/CT imaging was performed. The SUVmax findings of primary tumors obtained from 18F-FDG PET/CT were compared between the groups. RESULTS Invasive ductal carcinoma was the most prevalent breast carcinoma (77.7%, n=446), with a low proportion of ABC (4.1%, n=24) and PBNEC (2.4%; n=14) diagnosed. The highest mean SUVmax was calculated in HER2 subtype of ABC and 18F-FDG uptake ratio in HER2 and TN subtypes were found statistically higher than Luminal B type of ABC (p=0.038 and p=0.019, respectively). Although 18F-FDG uptake in Luminal B subtype of PBNEC was higher than Luminal A subtype, difference was not statistically significant. Additionally, the axillary metastasis rate was significantly higher in the ABC group (p=0.015). CONCLUSIONS The histopathological ABC subtype group showed different 18F-FDG uptake than the invasive ductal carcinoma group. Even if 18F-FDG uptake was lower in the PBNEC group than in the other groups, PET/CT showed and adequate performance in detecting primary tumors and metastases. The 18F-FDG PET/CT scan results may contribute to the initial staging and management of ABC and PBNEC patients.

Abstract
Objectives Repeated admissions of patients with undiagnosed psychiatric problems in emergency departments (ED) is a major contributor to patient unsatisfaction and overcrowding in EDs. We evaluated the presence of psychiatric disorders in non-emergent admissions in the ED of a tertiary care hospital. Materials and Methods This cross-sectional study was carried out in Eskisehir Osmangazi University Hospital between December 2015 and March 2016. The study group consists of 4320 non-emergent patients (31% of all admissions to non-emergent ED). Psychiatric assessments of patients were done using the Primary Care Evaluation of Mental Disorders (PRIME-MD) scale prior to their discharge from the ED. The Mann-Whitney U, Kruskal-Wallis and Chi-square tests, as well as multivariate logistic regression, were performed for statistical analysis. Results The mean age was 30 ± 11.7 years years ranging from 18 to 78 years. Among non-emergent cases, 44% had at least one psychiatric disorder. The most frequent psychiatric disorder was mood disorder (major and minor depression). Females with a comorbid disease and lower education level had increased risk for mood disorders, anxiety disorders, and somatoform disorders. Single males with a comorbid disease had increased risk for alcohol dependence. Conclusions Undiagnosed patients with psychiatric disorders appear to be frequent users of medical emergency department services. These results might be helpful in developing more effective strategies to serve the mental health needs of the undiagnosed. People's awareness of psychiatric disorders should be increased.

Abstract
Many types of aflatoxin cause problems for both public and animal health. Aflatoxin B1 (AFB1) is the most toxic and commonly encountered fungal toxin that appears in poultry feed and in feeds stored under unsuitable conditions. AFB1 decreases feed quality, egg production and fertility of hatching eggs. Also, AFB1 alters the development of embryos by infecting eggs. We investigated using sequence analysis the changes caused by different concentrations of AFB1 on the promoter sequences of the growth hormone regulated gene-1 (GHRG-1) in chick embryo at 13, 17, 19 and 21 days incubation. DNA isolated from the liver of chick embryos treated with different concentrations of AFB1 was separated using agarose gel electrophoresis to detect apoptosis, and DNA interaction with AFB1 was investigated using plasmids to detect changes in electrophoretic mobility and their effects on DNA. Base changes of the promoter sequences of GHRG-1 in 5 ng/egg, 15 ng/egg and 40 ng/egg doses of AFB1 were increased on day 19 compared to base changes of the same AFB1 doses on day 13. We also found that AFB at different concentrations changed the mobility of DNA by binding to it, and that high doses of AFB1 destroyed DNA. The DNA interaction study using plasmid demonstrated that AFB1 at high doses was bound to plasmid DNA, slowed its mobility and inhibited restriction cuts.
