Book Beslenme Biyokimyası(Nobel Akademik Yayıncılık, 2022) Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi-Article Citation - WoS: 3Citation - Scopus: 3Thiol–disulfide balance and trace element levels in patients with seasonal allergic rhinitis(African Health Sciences, 2022) Savas, Hasan Basri; Gunizi, Huseyin; Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiAbstract Background: The prevalence of allergic diseases is gradually increasing worldwide. The most common such allergic disease is allergic rhinitis (AR). Objective: The present study investigated the possible relationship between seasonal AR and the thiol-disulfide balance and zinc and copper levels in adult individuals. Study Design and Methods: 130 male and female adults were included in the study. The participants’ serum thiol-disulfide balance and zinc and copper levels were measured spectrophotometrically using commercial kits. Statistical significance was accepted as p < 0.05 between the groups. Results: The serum copper (p = 0.001), native thiol (p = 0.006), reduced thiol (p < 0.001), and thiol oxidation reduction ratio (p < 0.001) levels were significantly lower in the seasonal AR group than in the control group. Conclusion: In AR patients, the low level of copper, which is an important trace element, the deterioration of the thiol-disulfide balance, which represents a unique indicator of the oxidant-antioxidant balance, the increased disulfide level caused by oxidative stress, and the decreased native thiol level can all serve as important biochemical markers.Article Response of Zinc Levels During Aerobic Exercise: A Special Connection between Increased Metabolic Stress and Altered Oxidant to Antioxidant Balance(Anatolia Sport Research, 2022) Kaya,Hüsamettin; Uğraş, Seda; Özdenk, Çağrı; 05.01.

Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiAchondroplasia is an autosomal dominant disorder. But 80% of cases are sporadic. Its incidence is between 1/25000 and 1.5/10000. Significant shortening of the femur and humerus occurs in patients with achondroplasia. This shortness causes the appearance of rhizomelic type of dwarfism. Since the skull of patients with achondroplasia is large during delivery, it may cause difficult delivery. During infancy, hypotonia is more dominant. Many patients also have delayed motor development. Our aim in the study is to present the successful physical therapy and rehabilitation process of our patient diagnosed with achondroplasia for one year and her condition from diagnosis to treatment. Our patient was born via cesarean section on 12.02.2020. The weight of the baby girl was 3500 grams. The mother's height was 162 cm. and the father's height was 174 cm. The mother was 23 years old and the father 27 years old. The same diagnosis was not present in any living relative of the patient. The patient was 1 year old when she applied to our center. She had completed head control and had not yet acquired the skills of rolling over, crawling, and sitting without support. Gross motor skills such as assisted standing and stepping were not developed. In this direction, after a 1-year physical therapy and rehabilitation period applied in 2 sessions a week, the patient gained the ability to walk independently.Article The effect of radiofrequency electromagnetic radiation on rat liver tissue and serum paraoxonase (PON1)(Annals of Medical Research, 2023) Yavaş, Mehmet Cihan; Kilitçi, Asuman; Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiAim: The development of technology increases the rate of everyone having a smartphone. Therefore, the possible biological effects of these devices are of concern. In this study, we aimed to investigate the effect of 2100 MHz radiofrequency electromagnetic radiation on rat liver tissue and serum paraoxonase 1 level. Materials and Methods: Within the scope of the study, a 2100 MHz radiofrequency electromagnetic radiation model was created. In our study, we used Sprague Dawley male rats. Two groups were made as sham-control and exposure group (5 h a day for 2 weeks). Liver tissue and serum paraoxonase were studied. Results: The paraoxonase 1 value of the exposure group was higher than the sham control group, and did not have statistically important difference in the comparison of exposure and sham control groups (p>0.05). Did not have important difference in histopathological parameters of rat liver tissue (p>0.05). Conclusion: Although it seems that radiofrequency radiation does not cause liver dam age, more detailed studies with short- and long-term exposure are neededArticle Is There a Relationship Between First-Trimester Aneuploidy Screening Serum Biomarker Values and Nuchal Translucency Measurements and the Development of Retinopathy of Prematurity (ROP) in Premature Infants?(Nature, 2023) Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiAbstract Purpose The purpose of this study is the evaluation of serum biomarker and nuchal translucency (NT) values measured during first-trimester aneuploidy screening in terms of the development of retinopathy of prematurity (ROP) in premature infants and investigation of whether the development of ROP is associated with these parameters. Methods In this retrospective cohort study, 3,750 premature infants who underwent ROP screening from 2016 to 2021 were identified from the hospital medical record system. Among 2,130 premature babies screened for firsttrimester aneuploidy, 166 babies whose mothers had single pregnancies were screened by the same method and showed the same clinical course in both eyes were included in the study. The infants were divided into two groups according to the presence of ROP, and those with ROP were further evaluated in two groups according to the presence of proliferation. The groups were compared in terms of the serum values of human chorionic gonadotropin and pregnancy-associated plasma protein A, among aneuploidy screening biomarkers, and NT measurements. Results There was no significant difference in the evaluated serum biomarker values and NT measurements between the ROP and non-ROP groups or between the proliferative ROP, non-proliferative ROP, and non-ROP groups. Conclusion Our results showed that first-trimester aneuploidy screening serum biomarker values and NT measurements were not associated with the development of ROP in premature infants.Article Anti-angiogenic and oxidative effects of brilliant blue at different concentrations in chorioallantoic membrane model(Modestum, 2023) Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiIntroduction: Artificial food colorings are increasingly used to make the color and appearance of foods more attractive. One commonly used food dye is E133, international-coded brilliant blue (BB). According to the European Food Safety Authority panel results in 2010, it was determined that BB daily remained below the acceptable daily intake (ADI) value for adults and exceeded ADI value for children. The purpose of this study was to investigate the effects of BB on angiogenesis and oxidative stress in the chorioallantoic membrane model. Materials & methods: In this investigation, fertilized chick eggs free of specific pathogens were used. The eggs that were not fully grown or fertilized were excluded. 50 embryos were distributed into five groups of 10 each. The negative control group was the control group, the positive control group was the bevacizumab group, and three different BB dosages (10-4 M, 10-5 M, and 10-6 M) were identified. At the end of the experiment, anti-angiogenesis scoring, and total antioxidant-oxidant capacity were evaluated. Results: According to the average score values, the control group had no anti-angiogenic impact, but the bevacizumab group had a strong anti-angiogenic effect (average score 1.1). Furthermore, the 10-4 M BB group had a weak anti-angiogenic impact (average score of 0.7), while the 10-5 M and 10-6 M BB groups had no anti-angiogenic effect (average score of 0.4 and 0.2, respectively). As a result of one-way analysis of variance test, it was seen that BB significantly increased total oxidant capacity and oxidative stress index values in proportion to the increase in dose (p<0.05). Conclusions: BB’s oxidant and anti-angiogenic effects indicate that high doses of processed foods containing artificial food dyes carry a risk for viable growth. Since there are not enough studies in the literature showing the oxidant or antiangiogenic effects of BB in chorioallantoic membrane model, the original data we presented in this study are pioneering.Article Anti-Angiogenic and Oxidant Effects of Monosodium Glutamate at Different Concentrations in Chorioallantoic Membrane Model(Muğla Sıtkı Koçman Üniversitesi, 2023) Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiMonosodium glutamate (MSG) is a flavor-enhancing food additive. MSG exposure is rising day by day because of the high commercial food consumption. MSG exposure causes damage to various tissues and organs. The aim of this study is to investigate the effects of MSG on angiogenesis and oxidant-antioxidant balance. Three different concentrations of MSG (10-4 M, 10-5 M, and 10-6 M), control, and the bevacizumab (10-6 M) were prepared and placed on the chorioallantoic membrane (CAM) of the embryos. Albumen was taken from the embryos before and after the experiment. Angiogenesis was investigated through the window that was opened on the eggshell. Angiogenesis was found to be normal in the control and 10-6 M MSG group (average score: 0.3). Anti-angiogenic effects were moderate in the 10-5 M MSG group (average score: 0.5) and in the 10-4 M MSG group (average score: 0.7), and strong in the bevacizumab group (average score: 1.1). According to our results, MSG shows anti-angiogenic properties in higher doses. MSG increased oxidative stress. According to the results of our research, it is seen that MSG inhibits angiogenesis in a dose-dependent manner in the CAM model and may cause an increase in oxidative damage by disrupting the oxidant-antioxidant balance. Since no previous study has been found in the literature regarding the effects of MSG on angiogenesis and oxidant-antioxidant balance in the CAM model, we think our results will fill an important gap in the literature.Book Part Endokrin Sistem Fizyolojisi(Akademisyen Kitapevi, 2023) Gökdemir, Gül Şahika; Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; 10.

Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiObjective: Legionnaires' disease is a fatal form of pneumonia brought on by an infection mostly caused by the 60 different species of Legionella pneumophila. Legionnaires' illness is caused by Legionella spp.-contaminated water systems. In this work, we sought to analyze Legionella species, serogroups (SG), and contamination in the water sources of hospitals in five regions in eastern Turkey. Methods: Between January 2017 and December 2018, a total of 1008 samples were examined, including 2 cooling towers, 62 hot water tanks, 104 cold water tanks, and 840 faucet shower heads. Samples were collected by the standard culture method L. pneumophila SG 1, it was analyzed for L. pneumophila SG 2-16 and Legionella spp. The samples were inoculated into BCYE and GVPC medium, and the colonies were assessed using a latex agglutination test, followed by species- and serotype-level identifications. Results: In our study, a total of 1008 water samples were examined, of which 35.31% (356) belonged to 2017, while 64.68% (652) belonged to 2018. 83.33% of the water samples were taken from faucets and shower heads, 10.32% from the cold water tank, 6.15% from the hot water tank, and 0.2% from the cooling tower, and the highest positivity rate was observed in the hot water tank with 12.60%. 7.04% (71) of the samples were positive, and 16.9% (12) of the positive samples were L. pneumophila SG 1, 77.46% (55) L. pneumophila SG 2-14 was detected, while 5.63% (4) were nonpneumophila (Legionella spp) it has been determined as. Conclusions: Legionella disease remains a significant public health threat. The water tanks of hospitals and hotels should be investigated more thoroughly, the necessary disinfection procedures should be carried out frequently. All hospitals should have water management policies, and towns and large buildings should establish comprehensive water system management programs that decrease Legionella growth and transmission. To enhance prevention measures and clinical diagnosis, we also need quicker ways of detecting Legionella in water systems and clinical samples.Article EFFECT OF METFORMIN ON MUSCLE ATROPHY IN EXPERIMENTAL DIABETIC RATS(2023) Gökdemir.Gül Şahika; Keşim, Dilek Aygül; Gökdemir, Mehmet Tahir; Baylan,Mukadder; Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; Department of Internal Medical Sciences / Dahili Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiBackground: Although first-line biguanide metformin is frequently administered to T2DM patients, the effects of long-term use on muscle are unknown. This study aimed to examine the effect of metformin-treated diabetes on muscle atrophy in experimental diabetic rats. Materials and methods: Twenty-one Wistar albino male rats in 3 groups were included in our research. Insulin resistance HOMA-IR, mTOR, and Myostatin levels and gastrocnemius weight were measured. Results: Myostatin level was significantly higher in the non-medicated diabetes group than in the healthy control group (p<0.001). Moreover, myostatin level was significantly lower in the metformin group (p=0.001). The weight of gastrocnemius was significantly lower in both the metformin-treated and non-metformin-treated diabetic groups compared to the control group (p<0.001 for both groups). Moreover, the gastrocnemius weight was significantly higher in the metformin group than in the non-medicated group (p=0.004). The HOME-IR level had a significantly negative correlation with the mTOR level (R=-0.783; P<0.001) and a positive correlation with the myostatin level (R=0.622; P=0.003). Conclusion: Our evidence and data support that metformin may be effective in preventing muscle wasting. To conclude, this study showed that metformin has anti-atrophic effects on muscles in diabetes and that metformin can prevent muscle mass loss.Article Importance of Curcumin Effect and Asprosin Level on Glucose Metabolism in Diabetic Rats(2023) Gökdemir, Mehmet Tahir; Taşdemir, Ezel; Yokus, Beran; Atmaca, Mukadder; Gokdemir, Gul SahikaAsprosin is a new hormone secreted mainly from white adipose tissue. It may be associated with the pathogenesis of obesity, diabetes and some metabolic diseases. The changes in plasma asprosin levels of experimental diabetic rats and the relation of these changes with liver glucose metabolism and some diabetes parameters were investigated, and the effects of metformin, gliclazide or curcumin treatment on plasma asprosin levels were tried. The study was designed as an animal model in diabetic rats The albino rats were divided into five groups. To induce diabetes, a single dose of STZ was injected intraperitoneally. Diabetics rats were treated intragastrically with metformin (D+Metformin group), gliclazide (D+Giliclazide group) or 20 curcumin (D+Curcumin group) for eight weeks. Fasting blood glucose, insulin levels and other parameters were measured. Plasma asporsin levels of untreated diabetic rats increased significantly (P<.001). Although the plasma asprosin levels of diabetic rats treated with the rugs were significantly lower (P<.001). Fasting blood glucose levels of diabetic rats treated with the drugs were found to be remarkably lower than the diabetic control values (P<.001, respectively). There was no significant difference in the insulin levels and HOMA- IR between these three groups. Curcumin treatment provides significant improvements in plasma asprosin level and diabetes parameters. The increase in plasma asprosin level in diabetic rats may be one of the main reasons that facilitate the development of the disease or is responsible for its pathogenesis. Our findings support the idea that curcumin may be an important treatment option for diabetes.Article Anti-angiogenic and oxidative effects of sodium benzoate at different concentrations in chorioallantoic membrane model.(Modestum, 2023) Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiAim: Due to the increased consumption of packaged foods, exposure to food additives is also increasing. Sodium benzoate (SB), a frequently used food additive, is generally used in alcoholic beverages, fruit, and vegetable juices, carbonated soft drinks, canned food, and various sauces. It is used to inhibit the formation of mold, yeast, and bacteria. This study was carried out to investigate the effects of SB exposure on angiogenesis and oxidant-antioxidant balance. Materials & methods: Three different concentrations of SB, bevacizumab, and empty pellets were prepared, placed on chorioallantoic membrane (CAM), and examined for antiangiogenesis. Total antioxidant capacity (TAC) and total oxidant capacity (TOC) measurements were made in the albumen samples, and oxidative stress index (OSI) value was calculated. Results: The control group had no anti-angiogenic effect, but the bevacizumab group had a strong anti-angiogenic effect.10-3 M SB had a weak anti-angiogenic effect, but 10-4 M SB and 10-5 M SB showed no anti-angiogenic effect. TOC levels increased with SB in a dose-dependent manner. TAC levels decreased depending on the dose in the experimental groups with SB application. OSI levels increased depending on the dose increase in SB. Conclusions: SB exposure caused a dose-dependent increase in oxidative stress and antiangiogenic effect in CAM model.Article Is There a Relationship Between First-Trimester Aneuploidy Screening Serum Biomarker Values and Nuchal Translucency Measurements and the Development of Retinopathy of Prematurity (ROP) in Premature Infants?(Springer, 2023) Küçük, Mehmet Fatih; Savaş Hasan Basri; Süren, Elçin; Erol, Muhammet; Yaprak, Lütfiye; Sabancı, Şenol; Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; 10.

Mardin Artuklu University / Mardin Artuklu ÜniversitesiPurpose The purpose of this study is the evaluation of serum biomarker and nuchal translucency (NT) values measured during first-trimester aneuploidy screening in terms of the development of retinopathy of prematurity (ROP) in premature infants and investigation of whether the development of ROP is associated with these parameters. Methods In this retrospective cohort study, 3,750 premature infants who underwent ROP screening from 2016 to 2021 were identified from the hospital medical record system. Among 2,130 premature babies screened for first-trimester aneuploidy, 166 babies whose mothers had single pregnancies were screened by the same method and showed the same clinical course in both eyes were included in the study. The infants were divided into two groups according to the presence of ROP, and those with ROP were further evaluated in two groups according to the presence of proliferation. The groups were compared in terms of the serum values of human chorionic gonadotropin and pregnancy-associated plasma protein A, among aneuploidy screening biomarkers, and NT measurements. Results There was no significant difference in the evaluated serum biomarker values and NT measurements between the ROP and non-ROP groups or between the proliferative ROP, non-proliferative ROP, and non-ROP groups. Conclusion Our results showed that first-trimester aneuploidy screening serum biomarker values and NT measurements were not associated with the development of ROP in premature infants.Article Ameliorating effects of low-dose ketamine administrations on opioid-induced memory impairments and neurodegeneration in mice(İnönü Üniversitesi Tıp Fakültesi, 2023) Uyar, Emre; Şeker, Uğur; Özhan, Onural; Açıkgül, Muhammet Burak; Çolak, Mehmet; İzci, Sevde Feyza; Parlakpınar, Hakan; Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiAim: Opioids have indispensable roles in pain management. A strong link exists between opioid use and memory impairments, mainly with continuous use. This study investigated the effects of two opioid drugs, meperidine and fentanyl, on emotional memory functions, brain morphology, and the possible protective effects of low-dose ketamine in mice. Materials and Methods: A passive avoidance (PA) test was used to measure emotional memory functions following seven daily drug applications in 48 male Balb/C mice (30-35 g). Meperidine (10 mg/kg), fentanyl (0.3 mg/kg), ketamine (5 mg/kg), and combinations of ketamine with the opioids were intraperitoneally injected daily. No drugs were utilized during the testing days. Brain tissues were obtained after sacrification and put into diluted formalin solution for histopathological analysis. Results: Transfer latencies of the meperidine and fentanyl-treated groups in the PA test were lower than in the vehicle-treated group (p<0.01, p<0.05, respectively). Ketamine combined with meperidine had higher latencies than in the meperidine-treated group (p<0.05). The augmenting effects of ketamine were evident against fentanyl and meperidine-induced neurotoxicity as morphologic alterations were reduced. Conclusion: Low-dose ketamine may fend against opioid-induced neurotoxicity and emotional memory impairments, especially against meperidine, which can be a practical alternative to fentanyl in clinical settings.Article COVID-19 Pandemisi Süresince Huzurevinde Kalan Yaşlıların Hijyen Alışkanlıkları Üzerine Bir İnceleme(Muş Alparslan Üniversitesi, 2023) Efe, Mehmet; Dicle, Yalçın; Pamuk, Deniz; Yalçın; Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; 10.

Mardin Artuklu University / Mardin Artuklu ÜniversitesiAbstract: Objective: Because the number of aging population is rising gradually this descriptive study is to evaluate the behaviors of individuals’ hygiene residing in residential homes during COVID-19 Pandemic. Method: The study was conducted through face-to-face interviews with 100 elderly individuals residing in nursing homes in two cities within the borders of the Eastern Anatolia Region, one of which has normal and the other metropolitan status. Data were collected with a socio-demographic information questionnaire and a questionnaire examining behaviors related to the mask-distance-cleanliness triad to protect against disease. Pearson chi-square analysis was applied to express the relationship between the groups. Results: A statistically significant relationship was found between the variable of the participants' COVID-19 recovery status and the use of masks indoors. (p: 0,008; r= .514) It was determined that there was a statistically significant relationship between the variable of COVID-19 transmission status of residential home residents and the use of hand sanitizer also there was a statistically significant relationship between the variable of the participants' status of having COVID-19 and the frequency of visitors to their rooms (p: 0,001; r= .646). Conclusions: Although the hygiene behaviors gained in order to prevent and reduce transmission during the pandemic are approaching the ideal level, it has been understood that more attention should be paid to the use of masks and social distance.Article Retrospective Evaluation of Tularemia Cases in Muş Province: 2011-2022(Mardin Artuklu University, 2023) Dicle, Yalçın; Aydın, Elif; Şen Gündoğan, Nesibe Efruz; Yalçın; Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiObjective: Tularemia is a bacterial disease of humans, wild and domestic animals. Recently, an increase in human tularemia cases has been observed in many countries worldwide. This study aimed to calculate the incidence of tularemia cases in Muş, determine the seasonal distribution of cases, and describe the socio demographic and clinical characteristics of tularemia cases detected over a twelve-year period. Methods: Data from 162 patients diagnosed clinically and serologically with tularemia and admitted to health facilities in Muş province between 2011 and 2022 were retrospectively analysed. Results: In our study, among 162 tularemia patients with F. tularensis microagglutination test titres of 1/160 and above, the ratio of male and female cases was equal (50%), and the mean age was 24.51 years. In the twelve-year evaluation, there were two major epidemics, and the most cases were seen in 2018 with 37 cases. Most cases were observed in winter (38.3%) and autumn (25.3%). Oropharyngeal tularemia was the most common form (64.2%) among the cases evaluated. Similar disease was found in 33.3% of patients living in the same neighbourhood as the patients, and no mortality was observed in any of the patients. Conclusion: As the oropharyngeal form is the most common, contact with contaminated water should be questioned, rodent and tick populations should be monitored and detailed epidemiological studies should be conducted. We believe that hygiene and sanitation measures are important with regard to tularemia outbreaks.Article Detection of Human Brucellosis by Brucellacapt and Rose Bengal Test in the Endemic Area(Fazile Nur Ekinci Akdemir, 2023) Aydın, Elif; Dicle, Yalçın; Kaçtaş, Şerif; Gümüş, Ali Furkan; Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiAbstract: Although brucellosis is the most common zoonosis in the world, it remains an infectious disease that has not received sufficient attention. There are a few tests detecting brucellosis by serum. Rose Bengal Test is an advantageous one. Our aim with this study was to compare Rose Bengal and Brucellacapt tests in serum samples and draw attention to the advantages of the test. Between June 2019 and June 2021, 7827 serum samples sent to the public health laboratory with a provisional diagnosis of brucellosis were evaluated. The Rose Bengal and Brucellacapt test (Vircell, Spain) was used to diagnose infection. Samples with antibody titer ≥1/160 were considered positive. Of the 7827 samples included in the study, 354 (4.6%) of the total 7677 serum samples tested were RBT positive, 118 (3.1%) of the 3776 samples tested were BCAP positive, and 118 (3.3%) of the 3626 samples tested were both RBT and BCAP positive. It was found that seropositivity was significantly higher in female patients (p<0.10). RBT and BCAP test positivity were most frequently observed in the 25-34 year age group. Considering brucellosis cases in terms of seasonal changes; 10.7% of cases were found in spring, 52.4% in summer, 20.9% in fall, and 16% in winter. In suspected cases, RBT is still considered the ideal detection method because it is easy to use, inexpensive, sensitive, and provides rapid results. It was concluded that the BCAP test is suitable for diagnosis due to its ability to detect blocker and high titer antibodies.Article Citation - WoS: 1Citation - Scopus: 1The distribution and the antimicrobial susceptibility features of microorganisms isolated from the burn wounds; a ten-year retrospective analysis(Oxford University Press, 2023) Özkaçmaz, Ayşe; Dicle, Yalçın; Bayram, Yasemin; Parlak, Mehmet; Akış, Feride; Çallı, İskan; Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiIn this study we aimed to evaluate the distribution features and antimicrobial susceptibility test results of the microorganisms isolated from the wounds of pediatric and adult burn patients. The culture and susceptibility test results of the microorganisms isolated from the wound swabs of the patients hospitalised in a tertiary burn care center in 10-years period, were retrospectively screened on the microbiology department databases. Their distribution of isolated microorganisms regarding species and susceptibility test results were compared with previous studies. A total of 367 microorganisms isolated from the burn wounds of 293 patients (13± 18.9 years, F/M: 0.93) (73 adult and 220 pediatric patients), were included in this study. A solitary agent was isolated in 239 (81.6%) patients, while two were isolated in 43 (14.7%) and three or more agents in 11 (3.8%). From these, 33% of the isolated microorganisms were gram positive cocci, 61% were gram negative bacteria and 6% were Candida spp. The most common isolated microorganisms were Staphylococcus aureus (18.5%), Pseudomonas spp. (16.9) and Escherichia coli (%11.2), while the least common was Streptococcus spp. (2.5%). Methicillin resistance was 15% among the S. aureus strains. No resistance was observed against levofloxacin, vancomycin, teicoplanin, linezolid, daptomycin, fusidic acid and tigecycline in S. aureus strains. The highest resistance rates were observed against levofloxacin (64%), tobramycin (64%), pip/tazobactam (63%), imipenem (63%), and the lowest against colistin (5%) and ceftazidime (29%), among Pseudomonas spp. The most common causative agents in burn wound infections and their current antimicrobial susceptibility features should be well identified, in order for prevention of serious complications and optimal management the condition to occur.Article The protective role of selenium in an experimental high fructose corn syrup exposure.(Modestum, 2023) Department of Basic Medical Sciences / Temel Tıp Bilimleri Bölümü; 10. Faculty of Medicine / Tıp Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu ÜniversitesiObjective: Nowadays, fructose is recognized as a significant health threat. Prepared foods containing fructose are consumed more because they do not create a feeling of satiety. Selenium is an essential trace element with antioxidant and cell protective properties. In this study, the effect of high fructose corn syrup, which is used as a sweetener in many foods and beverages and consumed during pregnancy, and the possible protective role of selenium in this effect were investigated and examined. Methods: Fertilized specific pathogen-free eggs were used in our study. These eggs were divided equally into four groups. Each group was allocated 10 eggs containing viable embryos. These groups are pre-process control, post-process control, high fructose corn syrup (HFCS55), and high fructose corn syrup and selenium (HFCS-55+Se 10-6 ) groups. Pellets containing and containing no active substance (HFCS-55, HFCS-55+Se 10-6 ) were carefully placed on the chorioallantoic membrane (CAM) of each egg in these groups. Oxidative stress status in all groups was determined by total oxidative stress (TOS) and total antioxidant capacity (TAC) methods. Results: In our study, a significant increase in TOS levels and a significant decrease in TAC levels were observed in egg groups given HFCS compared to other groups (p<0.05). The OSI value was shown to be lower in the group given HFCS+Se. Conclusion: As a result, HFCS was shown to increase oxidative stress. In line with our data, it has been shown that Se, plays a protective role against oxidative stress.
