(Marmara Univ, Fac Medicine, 2024) Şener, Göksel; Ertas, Busra; Kaya, Rumeysa Keles; Sevinc, Sevgi Kocyigit; Amuran, Gokce Gullu; Ercan, Feriha; Cetinel, Sule; Eczacılık Meslek Bilimleri Bölümü
Objective: The aim of this study was to reveal the effect of apocynin (APO) on the factors involved in obesity-related endothelial dysfunction (ED) and atherosclerosis (AS). Materials and Methods: Male Wistar albino rats were divided into control (CNT), high-fat diet (HFD) and HFD+APO groups. HFD and HFD+APO groups were fed HFD for sixteen weeks. APO (25 mg/kg) was administered to the HFD+APO group for the last four weeks. The effects of APO on: AS-related metabolic parameters (triglyceride, total cholesterol, high-density lipoprotein-cholesterol, insulin and leptin), oxidative stress (OS), [ malondialdehyde, glutathione, nicotinamide adenine dinucleotide phosphate (NADPH)oxidase-2, oxidised-low-density lipoprotein (ox-LDL) and 8-hydroxy-2-deoxyguanosine], low-density lipoprotein and ox-LDL uptake potential (activin receptor-like kinase-1 and lectin-like oxidized low-density lipoprotein receptor-1, respectively), tissue inflammation inducible-nitric oxide synthase, nitric oxide), programmed cell death (terminal deoxynucleotidyl-transferase-dUTP-nick-end (alpha-smooth muscle actin), histology and ultrastructure of thoracic aorta were evaluated. Results: In obesity, APO had an ameliorative effect on metabolic parameters, OS, inflammation, ED, programmed cell death and oxLDL uptake potential, but not on foam cell formation and LDL uptake potential. Conclusion: Apocynin may improve ED and AS in obesity by suppressing OS-linked factors involved in the early stage of AS.

(Marmara Univ, Fac Medicine, 2023) Özkaya, Şebnem Özgen; Ozkaya, Sebnem Ozgen; Beslenme ve Diyetetik Bölümü
Objective: This study aims at examining dietary intake in children and adolescents with type 1 diabetes mellitus (DM) and comparing the results with national dietary intake recommendations. Patients and Methods: One hundred fifty children and adolescents (52.7% female) with an average age of 12.2 +/- 3.1 years and with type 1 DM who were followed by the Pediatric Endocrinology Polyclinic participated in the study. Three-day food intake records and clinical information regarding the type 1 DM condition of the participants were obtained. Results: No gender-related significant difference was found among the participants regarding food intake. The percentage of energy derived from fat (average 39.6%) and saturated fat (16.1%) were higher than the recommended levels in both gender groups. The percentage of energy derived from carbohydrates (female 44.1 +/- 5.7%, male 43.0 +/- 6.8%) was below the recommended levels. The dietary fiber intake in children aged 6-10 years with type 1 DM met recommendations, whereas, it was below the recommended levels in other age groups. Micronutrient inadequacy was common in children and adolescents with type 1 DM. Conclusions: The authors believe that guidelines and programs are needed for children and adolescents with type 1 DM to reduce total fat and saturated fat intake, increase carbohydrate and dietary fiber intake up to the recommended levels, and prevent multiple micronutrient inadequacies.

(Marmara Univ, Fac Medicine, 2021) Şener, Göksel; Ozbeyli, Dilek; Sen, Ali; Cevik, Ozge; Sener, Goksel; Ercan, Feriha; Eczacılık Meslek Bilimleri Bölümü
Objective: Methotrexate (MTX) is a drug commonly used for the treatment of malign neoplastic and inflammatory diseases. Anti-oxidant and anti-inflammatory effects of bitter melon (BM) were reported. The aim of this study was to examine the effects of BM fruit extract on MTX-induced testicular and epididymal damage. Materials and Methods: Sprague Dawley male rats were divided into three groups (n=8) as control, MTX and MTX+BM. A single dose of MTX (20 mg/kg) was injected intraperitoneally to the MTX and MTX+BM groups. BM fruit extract (600 mg/kg) was applied to the MTX+BM group orally for 5 days. Testes were examined for general histopathology, proliferating and apoptotic cells. The epididymis samples were used for the evaluation of sperm morphology. Oxidative and inflammatory markers were analysed biochemically. Results: Increased abnormal spermatozoa, degenerated seminiferous tubules with increased apoptotic cells and decreased proliferative cells were observed in the MTX group. TNF-alpha, IL-1 beta, 8-hydroxy-2-deoxyguanosine and caspase-3 levels increased, superoxide dismutase and catalase levels decreased in both testis and epididymis samples. All these histological and biochemical parameters were ameliorated in the MTX+BM group. Conclusion: Methotrexate causes testis damage by decreasing spermatogenic cells and increasing apoptosis through oxidative stress and inflammation. BM extract improves testis and epididymis damage with its possible anti-oxidant and anti-inflammatory effects.

(Marmara Univ, 2022) Şener, Göksel; Genc-Kahraman, Nevin; Ipekci, Hazal; Ustundag, Unsal Veli; Tunali-Akbay, Tugba; Emekli-Alturfan, Ebru; Yarat, Aysen; Eczacılık Meslek Bilimleri Bölümü
Caloric restriction (CR) and exercise (EX) have impacts on improving metabolic risk factors. This study aimed to investigate the changes in the brain after EX and/or CR in metabolic syndrome (MeS) induced by a high fructose diet in rats. Sprague-Dawley male rats were divided into five groups. Drinking water including 10% fructose solution was given to rats for 12 weeks to develop a MeS rat model. Animals with MeS were submitted to EX and/or CR for 6 weeks. Blood glucose, and brain tissue damage and antioxidant parameters were measured. Brain lipid peroxidation, sialic acid, mucin, fucose levels increased in the MeS group compared to the control (C) group. These parameters reduced significantly in the metabolic syndrome with caloric restriction (MeS+CR) group, and more significantly in the metabolic syndrome with exercise and caloric restriction group (MeS+EXCR), compared to the MeS group. Glutathione levels, superoxide dismutase and catalase activities decreased in the MeS group compared to the C group, increased both in the MeS+CR group, and MeS+EXCR group compared to the MeS group. High fructose diet consumption can lead to brain tissue damage and decreased antioxidant levels were found to be improved best in the MeS+EXCR group.

(Acta Medica Belgica, 2024) Özdinçler, Arzu; Alpozgen, A. Zengin; Gungor, F.; Ozdincler, A. Razak; Altun, S.; Fizyoterapi Ve Rehabilitasyon Bölümü
Fear of movement, pain, and loss of shoulder function are the most common problems irrespective of their approach to management after proximal humeral fracture (PHF). However, it has been unclear whether there could be differences between both treatments in early clinical outcomes. It can help physiotherapists to guide in choosing treatment approaches. This study aimed to compare kinesiophobia, pain, range of motion (ROM), shoulder function, and Quality of life (QoL) in patients treated with either conservative (CT) versus surgical (ST) after PHF. In addition, it aimed to determine correlations between fear of movement and seconder outcome measures. This cross-sectional study enrolled the patients having 5-6 weeks (being permitted active movement) after being treated either CT or ST and receiving no physical therapy. Pain, passive and active ROMs, shoulder function, fear of movement, and QoL were evaluated. 42 patients were recruited. Kinesiophobia scores were similar (p=0.55) and moderate in both groups. There was a significant difference in degrees of shoulder active flexion, active and passive abduction in favor of the CT group (p=0.05, p=0.02, p=0.04, respectively). However, there was no difference between groups regarding the remaining clinical outcomes. Furthermore, kinesiophobia showed a moderate negative correlation with energy/fatigue, social functioning, and general health. These findings showed that patients treated surgically did not have more kinesiophobia, less function, and QoL before starting physiotherapy, despite having soft tissue damage and different types of fractures. However, surgically treated patients had significantly less range of motion.

(Marmara Univ, 2022) Şener, Göksel; Okuyan, Betul; Sen, Ali; Ercan, Feriha; Onel, Huseyin; Goger, Fatih; Sener, Goksel; Eczacılık Meslek Bilimleri Bölümü
The overall aim of the present research is to evaluate for the first time the curative effect of Cotinus coggygria leaves on burn injury in an experimental burn model along with its anti-inflammatory and antioxidant activity potential. Also, phenolic compounds of C. coggygria were characterised by LC-MS/MS. Wistar albino rats weighing 200-250 g were exposed to 90 degrees C bath for 10 s to induce burn injury, involving 30% of the total body surface area. In the treatment groups, 5% C. coggygria ethanol extract was applied topically as a cream immediately after the burn. Blood and skin tissue samples were taken after decapitation at the 4th and 48th hours following the burn procedure. Interleukin 1-beta (IL-1 beta) and tumour necrosis factor (TNF-alpha) were determined in serum samples, and hydroxyproline, prostoglandin E2 (PGE2), and myeloperoxidase (MPO) activity and 8-hydroxy-2'-deoxy-guanosine (8-OHdG) levels were determined in skin tissue samples. Increased levels of serum cytokines were decreased with C. coggygria treatment in both periods. MPO activity, prostaglandine (PGE2), and 8-OhdG levels increased, while hydroxyproline levels decreased due to burn damage. On the other hand, these parameters were returned to its normal levels with C. coggygria treatment. In addition, the tissue histology of animals treated with C. coggygria showed a complete epithelialization with increased collagenation. As a result, C. coggygria may be an alternative treatment approach for burns-induced skin damage and wounds.

(Kare Publ, 2024) Şener, Göksel; Dorucu, Dogancan; Gulerturk, Oznur; Sen, Ali; Cevik, Ozge; Cetinel, Sule; Sener, Goksel; Eczacılık Meslek Bilimleri Bölümü
OBJECTIVE: Nephrolithiasis is a common urological disease that can lead to renal failure. Oxidative stress has been shown to be a contributing factor for nephrolithiasis and many agents have been studied to prevent and treat oxidative stress-related nephrolithiasis and renal damage. Myrtus communis (MC) extract has been shown to be an important antioxidant in different animal models. In this study, MC extract was administered preventively or therapeutically to rats with kidney stones, and its effectiveness was investigated. METHODS: Wistar albino rats were divided into four groups (n=8); control (C), ethylene glycol (EG), EG+preventive MC, and EG+curative MC groups. The nephrolithiasis model was created by adding 0.75% EG to drinking water for 8 weeks. Ultimately, 24-hour urine was collected to measure calcium, citrate, and creatinine levels. After decapitation, kidney tissues were harvested for histological analyses, measurement of osteopontin and 8-hydroxydeoxyguanosine (8-OHdG) levels, and N-acetyl-beta-glucosaminidase (NAG), myeloperoxidase (MPO) and caspase-3 activities. RESULTS: In 24-hour urine samples, calcium, citrate and creatinine levels were decreased in the EG group, while oxalate levels were increased and in treatment groups these parameters returned to control levels. MPO, 8-OHdG, caspase-3 and NAG activity were significantly increased in tissue and these changes were reversed in both MC groups. Histological findings also supported the biochemical parameters. CONCLUSION: MC can reduce oxidative stress and histopathological changes in kidney tissues in rat nephrolithiasis model when used as either a preventive or therapeutic agent. If supported with further clinical trials, MC might have clinical implications in preventing oxidative renal cell injury and ultimately kidney stone formation.

(Istanbul Univ, 2022) Yılmaz Karaoğlu, Sümeyye; Tufan, Elif; Sivas, Guzin Goksun; Gokmen, Begum Gurel; Dursun, Ercan; Ozbeyli, Dilek; Tunali-Akbay, Tugba; Eczane Hizmetleri Bölümü
Objectives: The aim of this study was to determine the effects of whey proteins on methotrexate (MTX)-induced brain and small intestine damage. Materials and Methods: 30 Sprague Dawley rats (200-300 g) were divided into four groups: Control, control + whey, MTX, and MTX+whey. MTX was administered at 20 mg/kg (single dose) intraperitoneally to the MTX group rats, and 2 mg/kg of whey protein were administered by oral gavage for 10 days to the whey groups. Lipid peroxidation, glutathione, and nitric oxide (NO) levels, as well as glutathione-Stransferase and superoxide dismutase activities were measured in the brain and small intestine. SDS-polyacrylamide gel electrophoresis of the brain and intestine tissues were also carried out. Results: While MTX treatment caused oxidative damage in the brain and small intestine, whey protein administration ameliorated MTXinduced oxidative stress. MTX administration did not change the brain's NO level, while an increase in intestinal NO level was detected. Conclusion: MTX induced oxidative stress in the brain and small intestine changed the protein metabolism in these tissues regardless of reduced food intake. Consecutive 10-day administration of whey proteins has shown its therapeutic effect on MTX-induced brain and small intestine oxidative damage.

Objective: Bisphenol A (BPA) is a toxic compound that causes oxidative stress by disrupting antioxidant enzymes and promoting tissue lipid peroxidation. This study aimed to examine the impacts of BPA on serum oxidative stress in rats and to detect the antioxidant feature of Panax ginseng (PxG) in reducing BPA-induced oxidative stress. Materials and Methods: Wistar Albino rats (250-300 g) were divided into control, control + PxG, BPA, and BPA + PxG groups. 50 mg/kg BPA and 100 mg/g PxG were given for six weeks. Serum total antioxidant and oxidant status, lipid peroxidation, and glutathione levels were determined. Results: BPA administration increased total oxidant status and lipid peroxidation, while PxG administration to the BPA group decreased these parameters. PxG also increased total antioxidant status and glutathione levels compared to the BPA group. Conclusion: BPA was seen to cause an increase in oxidative parameters and PxG administration to restore the oxidative stress that was generated after BPA exposure, suggesting that this may help to prevent the adverse effects caused by BPA exposure.

(Ijrr-iranian Journal Radiation Res, 2021) Şahin, Sevim; Ozturk, A.; Gungor, G.; Karabey, A. U.; Sahin, S.; Duruksu, G.; Gundogdu, O.; Elektrik-elektronik Mühendisliği Bölümü
Background: The radiobiological effect of high dose rate FFF beams on the DU-145 cells was investigated with SBRT plans which have >10 Gy. Methods and Materials: To compare the radiobiological effect on DU-145 cell line four experiments designed: (1) the constant dose rate of 6 MV and 6 MV FFF with increased dose per pulse (2) the effect of dose per pulse while increasing instantaneous dose rate for 6 MV and 6 MV FFF, (3) the effect of increased average dose rate for 6 MV FFF and (4) the effect of protracted treatment time and modulation of 6 MV FFF beams. The survival fraction was counted with WST. Results: FF and FFF for 6 MV with same dose rate and treatment time has no effect on cell survival. Significant differences was observed on survival which were irradiated with 6 MV 600 MU/min and 6 MV FFF 1400 MU/min (p=0.024). There was no difference between 6 MV FFF 600 MU/min and 6 MV FFF 1400 MU/min for 10 Gy. The significant survival difference obtained for 20 Gy. The survival percentages for both 10 Gy and 20 Gy with Cyberknife were obtained higher than FFF. Conclusion: Our in-vitro study presented here show that higher dose rate and reduced treatment time might become a crucial factor for SBRT especially which has >10 Gy fraction dose.

Ethanolic Extract of Cotinus Coggygria Leaves Attenuates Crystalluria and Kidney Damage in Ethylene Glycol-Induced Urolithiasis in Rats
(Kare Publ, 2023) Şener, Göksel; Ozgur, Gunal; Ertas, Busra; Sen, Ali; Eker, Pinar; Sener, Tarik Emre; Sener, Goksel; Eczacılık Meslek Bilimleri Bölümü
OBJECTIVE: Nephrolithiasis is a common cause of kidney insufficiency. Nephrolithiasis is proven to be the result of various biochemical and inflammatory processes that result in crystal formation and subsequent aggregation. Cotinus coggygria L. (CCog) is a plant extract which has been used as a Turkish remedy for kidney stones. With this study, we planned to evaluate the effects of CCog extract in ethylene glycol (EG)-induced nephrolithiasis model in rats.METHODS: The study group comprised 32 Wistar albino rats which were divided into Control (C), EG, CCog Prophylaxis (CC+EG+CC), and CCog Treatment (EG+CC) groups. Stone formation was induced by adding EG (0.75%) into rat's drinking water. Normal drinking water was given to Control group for 8 weeks. Throughout the study period of 8 weeks, EG group was given only EG (0.75%) and CC+EG+CC group was given both EG and CCog. In EG+CC group, EG (0.75%) was given for 8 weeks whereas CCog was given for the past 4 weeks. After the 8th week, 24-h urine samples were collected. Rats were then sacrificed and kidney tissue samples were harvested. RESULTS: Metabolites (calcium, citrate) and creatinine in 24 h urine samples were decreased in CC+EG+CC and EG+CC groups. While hyperoxaluria was observed in the EG group, oxalate levels were similar to control levels in the P-CCog and C-CCog groups. The N-acetyl-beta-glucosaminidase and myeloperoxidase activities were both increased in EG group and these parameters were significantly decreased on CCog treatment.CONCLUSION: We can conclude that C. coggygria extract can have beneficial effect on lowering concentration of stone-forming metabolites in urine and consequently protect renal tissues from damage due to nephrolithiasis. C. coggygria extract can be considered as a potential prophylactic and therapeutic option in high-risk stone formers. Furthermore, our data confirm ethnobotanical use of CC against nephrolithiasis.

AIM: The aim of this study was to determine the problems, perceived stress, and coping with the stress of mothers of children with chronic diseases during the pandemic. METHODS: The study was conducted with cross-sectional design. The data were gathered from the mothers of children with chronic diseases who were followed up at the endocrine outpatient clinic of a hospital in Istanbul between February 1, 2021, and May 31, 2021. The data were collected by conducting face-to-face interviews with mothers of 117 children through information form, Perceived Stress Scale (PSS), and the Coping with Stress Scale (CSS). RESULTS: It was determined that 35.9% of the mothers stated that they had problems during the pandemic since their children suffered from chronic diseases. The mean scores of the mothers were 26.88 +/- 6.69 points for the PSS and 87.35 +/- 11.04 points for the CSS and there was a negative and weak correlation between their scale scores (r = -.190; p < .05). CONCLUSION: It was found that families faced many different problems during the pandemic, such as the treatment and control of their children. In case of extraordinary situations such as pandemics, nurses should provide planned guidance and counseling services to children with chronic diseases and their families in order to manage the negative situations they experience.

Evaluation of Hydrazide-Hydrazone and 4-Thiazolidinone Derivatives of Etodolac as Potential Anticancer Agents in Leukemia Cells
(Bentham Science Publ Ltd, 2024) Küçükgüzel, Şükriye Güniz; Averbek, Sera; Sevinc, Sevgi Kocyigit; Kilinc, Olca; Suzgun, Pelin Cikla; Kucukguzel, S. Guniz; Orun, Oya; Eczacılık Meslek Bilimleri Bölümü
Background Nonsteroidal anti-inflammatory drugs (NSAIDs), which are commonly used for their anti-inflammatory and analgesic properties, have also been found to prevent cancer. (+/-)(R,S) Etodolac is an NSAID that belongs to the class of cyclooxygenase-2 inhibitors. Various derivatives of etodolac are synthesized to boost its anti-proliferative action and lessen its potential negative effects. In our earlier studies, some novel derivatives of etodolac exhibited stronger cytotoxic effects on prostate cell lines and had similar effects on leukemia cells in pre-screening experiments.Objective Using the K562 leukemia cell line as a model, we sought to investigate the anti-cancer properties of a hydrazide-hydrazone derivative (SGK-205) and a 4-thiazolidinone derivative of etodolac (SGK-216).Materials and Methods In the current investigation, SGK-205 and SGK-216 compounds were administered to K562 cells for 24 and 48 hours at concentrations of 10, 25, 50, 75 and 100 mu M. Cell viability was assessed using the MTT test, and apoptosis by Annexin V-PI staining and mitochondrial membrane potential assays, together with mRNA expressions of apoptotic proteins. The levels of the proteins, HER2 and COX2, were also examined to evaluate COX2 inhibitory capacity.Results In K562 cells, there was a definite dose-dependent response to SGK-205 and SGK-216 compounds. Results from MTT viability tests, together with mitochondrial membrane potential measurements and Annexin V-PI staining, revealed that SGK-216 and SGK-205 significantly outperformed etodolac in terms of their apoptotic and anti-proliferative activities. The concentration range of 10-20 mu M for both chemicals was sufficient to start biological responses. Apoptosis was also investigated through the expressions of pro- and anti-apoptotic proteins. Additionally, gene expression research demonstrated SGK-205 to be a beneficial substitute to etodolac in lowering COX-2 and human epidermal growth factor receptor-2 (HER2) expression.Conclusion Our data indicated both derivatives to have higher anti-proliferative and apoptotic effects compared to etodolac. An overall assessment highlighting apoptotic induction potential, acceptable toxicity levels, a consistent dose-response relationship, and COX2 inhibitory actions, in particular, indicated SGK-205 as a viable novel therapeutic.

BACKGROUND: The aim of this study was to investigate the immediate effect of chiropractic high velocity low amplitude (HVLA) sacroiliac manipulation on muscle strength and balance in healthy individuals with asymptomatic dysfunction of the sacroiliac joint. METHODS: Quadriceps and hamstring muscle strength and balance were measured before and after the application in healthy individuals, using the Biodex Balance System and MicroFet 2 Hand Dynamometer (Biodex Medical Systems, Inc., Shirley, NY, USA). Balance was measured when the patients stood on their feet eyes open, and eyes closed. In total, 60 individuals were included in the study. They were divided into two groups and the experimental group had 40 individuals in total. No application was made to the control group. One-time chiropractic HVLA sacroiliac manipulation was applied to the experimental group. RESULTS: In the control group, the quadriceps muscle strength of the right leg was 58.51 kg in the first measurement and 52.95 kg in the second measurement. The left leg yielded 57.62 kg in the first measurement and 51.06 kg in the second measurement. The Hamstring Muscle Strength of the right leg in the control group was 41.77 kg in the first measurement and 38.28 kg in the second measurement. In the left leg, it was 41.96 kg in the first measurement and 39.36 kg in the second measurement. For balance measurement, there was a significant improvement in balance in the second measurement in both eyes-closed and eyes-open positions. In the experimental group, the Quadriceps Muscle Strength of the right leg was 58.05 kg in the first measurement and 67.43 kg in the second measurement. In the left leg, it was 56.23 kg in the first measurement and 64.97 kg in the second measurement. Hamstring muscle strength increased significantly in both right and left legs after chiropractic HVLA manipulation (P<0.05). In the experimental group, the hamstring muscle strength of the right leg was 34.68 kg in the first measurement and 43.29 kg in the second measurement. In the left leg, it was 35.96 kg in the first measurement and 43.64 kg in the second measurement. CONCLUSIONS: There was no significant improvement in balance of both legs in eyes-closed and eyes-open position after chiropractic HVLA manipulation.

(Springer india, 2022) Dönmez, Ramazan; Gormez, Aysegul; Tıbbi Hizmetler ve Teknikler Bölümü
To evaluate the compatibility of preoperative 3D magnetic resonance cholangiopancreatography (3D MRCP) and intraoperative cholangiographies (IOC) of donors using Huang classification in living donor liver transplantation. Thirty-six consecutive right donor hepatectomy cases were retrospectively analyzed with preoperative MRCP and intraoperative cholangiography. Biliary variants were determined according to the Huang classification. Compatibility in MRCP and IOC was evaluated. 3D MRCP accurately determined the biliary anatomy in 32 of 36 cases (88.88%). The IOC of the 36 donors showed 25 normal bifurcations and 11 biliary variants. For detecting normal and variant anatomy, sensitivity, specificity, PPV, and NPV were 96.0%, 72.7%, 88.9%, and 88.9.0%, respectively. There was a substantial inter-rater agreement between IOC and MRCP in determining normal and variant anatomy (kappa = 0.724, p < 0.001). 3D MRCP is a non-invasive useful method to evaluate non-dilated bile ducts preoperatively in living donor liver transplantation. The eligibility criteria determined according to preoperative MRCP images should also be confirmed by intraoperative cholangiography.
