Abstract
BACKGROUND Various types of nasal tampons are used for packing after septoplasty. Intranasal splints are widely used as they are more advantageous than other materials regarding the lower complication rates of synechia, and lesser pain during removal. However, there is no consensus on the timing of intranasal splint removal after septoplasty operations. AIM In this study, we aimed to investigate the effects of removal time of intranasal splints on postoperative complications after septoplasty. METHODS One hundred patients who had septoplasty were randomly divided into two groups according to splint removal time. In group I, the splints were removed on the third postoperative day and in group II, splints were removed on the seventh postoperative day. Pain during splint removal was evaluated by visual analog scale (VAS). Complications of hemorrhage, septal hematoma, crusting, mucosal injury, and infection were recorded during splint removal and compared. In the first postoperative month, hemorrhage, crusting, mucosal injury, infection, synechia, and in the second postoperative month, synechia and perforation rates were compared between two groups. RESULTS Mucosal crusting was significantly higher in group II during splint removal. There was no statistically significant difference between the two groups regarding the complication rates and pain scores. Our findings showed no significant difference in pain scores during splint removal and postoperative complications between the two groups except for mucosal crusting. CONCLUSION Based on our findings, although there is no consensus on the optimal time for splint removal, earlier removal of splints can be considered a favorable option after septoplasty operations.

Abstract
OBJECTIVE This study aimed to evaluate the effects of affected knee flexion for 24 vs. 72 hours on blood loss, pain, range of motion, and functional outcomes after total knee arthroplasty. PATIENTS AND METHODS The present study included 46 participants with a mean age of 64.33 ± 6.70 years. The affected knee of the first 23 participants, based on the order of operations, was positioned at 70° flexion for 24 hours, and the knee of the next 23 participants was positioned at 70° flexion for 72 hours. Participants were evaluated before the operation and on postoperative day 3 and week 6. Pain, edema, range of motion, time up and go test scores, and Western Ontario McMaster Universities Arthritis Index scores, hemoglobin, and hematocrit were measured before the operation and on postoperative at day 3 and week 6. RESULTS We found that the calculated blood loss was 575.07 ± 282.44 and 578.39 ± 297.11 mL in patients who underwent short- and long-duration flexion positioning, respectively (p = 0.921). The active flexion angles at postoperative week 6 were 83.61° ± 22.03° and 105.91° ± 13.06° in the short- and long-duration flexion groups, respectively (p < 0.01). Furthermore, the Western Ontario and McMaster Universities Arthritis Index scores at postoperative week 6 were 35.52 ± 24.71 and 17.17 ± 15.37 in the short- and long-duration flexion groups, respectively (p < 0.01). CONCLUSIONS Long-duration flexion positioning after total knee arthroplasty may lead to better middle-term flexion range of motion and physical function scores than short-duration flexion positioning.

Abstract
Verbascum thapsus (VT) is a medicinal plant that is used in folk medicine to treat a variety of ailments. For this study, the biological functions of VT methanol extract were determined in vitro. The plant's methanol extract was created through the maceration process. The phytochemical composition of plant extracts was investigated using liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS). The antioxidant capacity of the extract was determined using the DPPH (2,2-diphenyl-1-picrylhydrazil) and ABTS (2,2-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) tests and its cytotoxicity was assessed using the MTT ((3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, a tetrazole)) assay on the Caco-2 (human colorectal adenocarcinoma cells), LNCaP (Lymph Node Carcinoma of the Prostate), and HEK293 cell lines (Human embryonic kidney 293 cells) used to model colon, prostate, and non-cancerous cells. VT extract showed low DPPH and ABTS radical scavenging activities compared to standard antioxidants at 30 mg/ml concentration. In addition, it was determined that VT extract inhibited acetylcholinesterase enzyme.

Abstract
OBJECTIVE This study aimed to investigate the relationship between hypercortisolism and temporal muscle thickness (TMT) in Cushing's disease (CD). METHODS A retrospective review of medical records was conducted for patients with CD who presented to our clinic between 2012 and 2022. Biochemical data and TMT measurements from sella imaging were evaluated during diagnosis and the first postoperative year. RESULTS A total of 44 patients were included in the study, with an average age of 43.9 years, of which 38 were female. The mean TMT at the time of diagnosis was 19.07 ± 1.71 mm, with no significant difference between males and females (p = 0.097), and no correlation between the TMT and age at diagnosis (p = 0.497). There was an inverse relationship between TMT and serum cortisol levels, 24-h UFC, and midnight salivary cortisol at the time of diagnosis of CD (p < 0.05, for all). One year after surgery, TMT significantly increased in all patients compared to baseline (p < 0.001). Furthermore, patients who achieved postoperative remission had significantly higher TMT values compared to those who did not achieve remission (p = 0.043). Among the patients who achieved remission, those who achieved remission through surgery had significantly higher TMT compared to those who could not reach remission with surgery and patients who started medical treatment and achieved biochemical remission (p = 0.01). Patients with severe myopathy and sarcopenia had significantly lower TMT values than the others (p < 0.001). CONCLUSION Temporal muscle thickness was found to be associated with disease activity and disease control in Cushing's disease.

Abstract
OBJECTIVE The present research aimed to study the possible protective effects of Silymarin on testicular I/R injury in a rat model evaluated through histopathology and biochemical parameters. MATERIALS AND METHODS This research investigated the impact of Silymarin on IR damage in male Wistar albino rats. Animals were divided into three groups: group 1 (sham), group 2 (IR), and group 3 (IR+Silymarin). RESULTS There were no notable differences in the levels of malondialdehyde (MDA), myeloperoxidase (MPO), and glutathione (GSH) across the three groups (p=0.260, p=0.486 and p=0.803, respectively). Contrarily, the total antioxidant status (TAS) levels exhibited significant variations between groups (p=0.001). The total oxidant status (TOS) levels also differed significantly between groups (p=0.004). The tissue evaluations uncovered substantial differences in the Johnson score, which is used to gauge testicular damage. A distinct contrast was seen between Group 1 and Group 2, and also between Group 2 and Group 3, with an all-encompassing p-value lower than 0.01. The same significant disparities were found for the percentages of Bax and Annexin V immunostaining (p<0.01 for each), reflecting the inflammation and apoptosis brought about by ischemia-reperfusion and the protective effects of the treatment. CONCLUSIONS The outcomes of the current investigation showed that Silymarin could be a valuable agent for reducing testicular tissue damage following I/R injury.

Abstract
OBJECTIVE Depression affects adolescents worldwide and often predicts more serious disease manifestations in later lifetimes. Peer victimization or bullying, another form of child abuse, increases symptoms of depression. In this paper, the relationship between peer bullying and depression in adolescence was investigated. SUBJECTS AND METHODS Each adolescent who was admitted to the adolescent unit completed forms referred to as the 'Depression Scale For Children' and the 'Multidimensional Peer Victimization Scale'. Sociodemographic features and results of the scales' evaluation were studied. SPSS 16.0 program was used for statistical analysis. The p-value below 0.05 was considered statistically significant. RESULTS 239 adolescents, 120 of whom were male, were investigated. A positive relationship was determined among total and sub-scale scores of peer victimization-determining scale and depression scale scores. A negative relationship was determined between height, weight, age of the child, and sub-scale score of threat/intimidation. Both the total score of the peer victimization-determining scale and sub-scale scores of ridicule, open attack, and relational attack pertaining to patients with depression proved to be significantly higher than in those without depression. CONCLUSIONS The awareness of educators and parents, notably adolescents, must be raised in regard to peer victimization, and activities for increasing the communicative skills of adolescents and for allowing them to be able to express their emotions should also be performed. Identifying and preventing peer victimization, one of the causes of depression, and launching the treatment process for this are the first steps to be taken in terms of a healthy adulthood.

Abstract
Diabetic nephropathy (DN), a severe diabetes complication, causes kidney morphological and structural changes due to extracellular matrix accumulation. This accumulation is caused mainly by oxidative stress. Semi-essential amino acid derivative taurine has powerful antioxidant and antifibrotic effects. The aim of this study was to investigate the renoprotective effects of taurine through its possible roles in oxidative stress, extracellular matrix proteins, and the signaling pathways associated with the accumulation of extracellular matrix proteins in DN rats. 29 Wistar albino rats were randomly separated into control, taurine, diabetes, and diabetes + taurine groups. Diabetes animals were injected 45 mg/kg streptozosine. Taurine is given by adding to drinking water as 1% (w/v). Urine, serum, and kidney tissue were collected from rats for biochemical and histological analysis after 12 weeks. According to the studies, taurine significantly reduces the levels of malondialdehyde (MDA), total oxidant status (TOS), and protein expression of NADPH oxidase 4 (NOX4) that increase in diabetic kidney tissue. Also, decreased superoxide dismutase (SOD) activity levels significantly increased with taurine in diabetic rats. Moreover, increased mRNA and protein levels of fibronectin decreased with taurine. The matrix metalloproteinase (MMP)-2 and MMP-9 activities and their mRNA levels increased significantly, and this increase was significantly summed with taurine. There was a decrease in mRNA expression of Extracellular matrix metalloproteinase inducer (EMMPRIN). Taurine significantly increased this decrease. Diabetes increased mRNA expressions of transforming growth factor (TGF)-β and Smad2/3. Taurine significantly reduced this induction. TGF-β protein expression, p38, and Smad2/3 activations were also inhibited, but taurine was suppressed significantly. All these findings indicate that taurine may be an effective practical strategy to prevent renal diabetic injury.

Abstract
Background Type 1 fascia graft tympanoplasty (T1FGT) is the mainstay surgical approach for the treatment of tympanic membrane perforations. The most widely used graft material is temporal muscle fascia, and graft take rates are reported differently. The methods to enhance graft take are still being investigated. Aim: The aim of our study was to investigate the effect of titanium-prepared platelet-rich fibrin (T-PRF) on graft take and hearing outcomes in T1FGT. Materials and Methods Fifty-seven ears eligible for T1FGT were involved in the study and prospectively evaluated. T-PRF was applied with T1FGT in 27 ears. Thirty ears in the other group underwent only T1FGT. The patients underwent an otomicroscopic and audiometric examination in preoperative and postoperative 2nd week, 1st month, and 6th month. Both groups were evaluated in terms of hearing levels, infection, and graft take rates. Results Two patients in the T1FGT + T-PRF group and seven patients in the T1FGT group had postoperative perforation (graft take rate: 92.6% versus 76.7%). The graft take rate was found to be increased in the T-PRF group although the difference was not statistically significant. In the T1FGT group, the percentage of infection was higher than in the T1FGT + T-PRF group. When the preoperative and postoperative 6th-month audiometry was compared, a statistically significant hearing gain was obtained for both groups. Conclusion In the treatment of tympanic membrane perforations, T-PRF applied over the fascia graft was shown to increase graft take rates and decrease the probability of infection. Further studies with larger samples are needed to demonstrate the effects of PRF.

Abstract
Renal ischemia-reperfusion (I-R) injury is a complex pathophysiologic condition characterized by oxidative stress, inflammation and apoptosis. We investigated the potential renoprotective effect of nebivolol, a β1 adrenergic receptor blocker, against renal I-R injury. We focused on the role of nebivolol in activating p38 mitogen-activated protein kinase (MAPK) signaling, Akt (protein kinase B) and nuclear factor-κB (NFκB) transcription factors, which contribute to oxidative stress, inflammation and apoptosis during renal I-R. We divided 20 adult male Wistar albino rats into three experimental groups. Group 1 was a sham control in which only laparotomy was performed. Group 2 was the I-R group in which both kidneys were made ischemic for 45 min, then reperfused for 24 h. Group 3 was the I-R + nebivolol group in which 10 mg/kg nebivolol was administrated by gavage for 7 days before I-R. We measured Inflammation, oxidative stress and active caspase-3 as well as activation of p38 MAPK, Akt (protein kinase B) and NFκB transcription factor. Nebivolol significantly reduced oxidative stress and increased superoxide dismutase levels during renal I-R. We found that nebivolol significantly decreased interstitial inflammation, and TNF-α and interleukin-1β mRNA expression. Nebivolol significantly reduced active caspase-3 and kidney injury molecule-1 (KIM-1) expressions. Nebivolol also significantly decreased activation of p38 MAPK signaling and NFκB, and induced Akt activation during renal I-R. Our findings suggest that nebivolol may be useful for management of renal I-R injury.

Abstract
Aim Diabetic macular oedema (DME) can develop at all stages of diabetic retinopathy, causing visual impairment and blindness. Modern diets are high in advanced glycation end products (dAGEs), derived from processing methods, exerting a pivotal role in promoting diabetic retinopathy risk. In present study, we investigate the relationship between dietary and serum levels of AGEs and DME in type 2 diabetic subjects. Methods This case-control study was conducted between July 2018 and February 2019 on 50 case subjects with DME and 40 healthy controls without DM without DME. The sociodemographic characteristics, nutritional status, and anthropometric measurements were evaluated. The advanced glycation end products (AGEs) and receptor for AGEs (sRAGE) levels in serum were analysed. Results The AGEs levels of the DME group were higher than in the control group (p <0.05). sRAGE levels were higher in the DME group, but not statistically significant (p >0.05). The dietary intake of AGEs was higher in the DME group (p <0.05). It was found that an increase in neck circumference increased the risk of DME (p <0.001). Conclusion A positive correlation was found between DME and AGEs, dAGE, neck circumference, and waist circumference. For the validity of these results, studies, including controlled nutrition interventions, are needed.

Abstract
BackgroundThe frequency of pulmonary rheumatoid nodules closely relates to the diagnostic modality and changes from <0.4% to 32%. Also, it is known that seropositive RA patients tend to have more extra-articular disease.ObjectivesWe aimed to compare the disease and pulmonary rheumatoid nodule characteristics of seropositive and seronegative RA patients.MethodsIn this study, all RA patients - according to ICD-10 code - and had at least one chest computerized tomography (CT) were examined and revealed 4117 individual patients. First, RA diagnosis was confirmed according the patients’ history, physical examination, radiography and laboratory assessment. Then, chest CTs were examined by an experienced radiologist. To classify pulmonary nodules as ‘’pulmonary rheumatoid nodule’’, following inclusion and exclusion criteria were used; For inclusion: 1) nodules with changing dimension on follow-up, 2) At least two nodules with different dimensions, 3) Cavitary nodule at any chest CT. For exclusion: 1) Solitary nodules OR all nodules ≤ 5mm and without follow-up OR no change on follow-up. Biggest nodule was named as dominant nodule. Then, patients were grouped according to rheumatoid factor and anti-CCP status as seropositive (RF ± anti-CCP) and seronegative. Demographics, comorbidities, RA-spesific treatments and nodule characteristics were compared.ResultsOf 680 RA patients who had pulmonary nodule in chest CT, 208 (30.6%) patients were classified as having pulmonary rheumatoid nodule. 167 (80.3%) patients were seropositive. Demographic and comorbidity characteristics were similar among seronegative and seropositive patients (Table 1). Regarding RA-spesific treatments, methotrexate, leflunomide and rituximab were prescribed more frequently in seropositive patients. For nodule characteristics, seropositive patients had higher number of nodules (5 [1-48] vs 3 [1-27]; p=0.004), bigger dominant nodule (8 [3-95] vs 6 [3-45] mm; p=0.011), and higher percentage of cavitary nodule (28.7% vs 12.2%; p=0.03). Localization of the nodule was compareble.Table 1.Comparison of demographic, disease and nodule characteristics of seropositive and seronegative patients (n=208)Seropositive (n=167, 80.3%)Seronegative (n=41, 19.7%)P valueFemale, n(%)113 (67.7)28 (68.3)0.94Age at the time of CT (median, min-max)61 (24-83)59.7 (20-83)0.28Smoking (n=73)26 (43.3)4 (30.8)0.40- Never smoked34 (56.7)9 (69.2)- Ever smokedComorbidity (n=188)127 (84.7)30 (78.9)0.40- Hypertension72 (55.0)18 (58.1)0.91- Diabetes (n=166)25 (18.5)7 (22.6)0.79- CAD (n=165)30 (22.6)7 (21.9)0.93- Heart Failure (n=164)15 (11.4)6 (18.8)0.41- COPD (n=163)20 (15.2)1 (3.2)0.13- Asthma (n=160)15 (11.6)5 (16.1)0.54- CKD (n=169)20 (14.5)8 (25.8)0.22- ILD (n=202)54 (33.1)10 (25.6)0.37RA-spesific treatments (ever)90 (72.6)16 (55.2)0.07- Methotrexate (n=153)105 (64.0)12 (30.8)0.001- Leflunomide (n=208)117 (70.5)25 (61.0)0.06- Hydroxchloroquine (n=169)65 (47.4)11 (36.7)0.28- Sulfasalazine (n=167)39 (39.0)6 (27.3)0.30- TNFi (n=122)41 (39.8)2 (9.5)0.008- Rituximab (n=124)11 (9.9)2 (8.0)0.77- Tofacitinib (n=136)12 (11.9)2 (10.5)0.86- Abatacept (n=120)9 (8.5)2 (8.7)0.98- Tocilizumab (n=129)Number of nodules at baseline CT (median, min-max)5 (1-48)3 (1-27)0.004Diameter of dominant nodule (median, min-max) (mm)8 (3-95)6 (3-45)0.011Localization of dominant nodul64 (38.3)15 (36.6)0.84- Left or right?64 (38.3)12 (29.3)0.48◦ Left51 (30.5)16 (39.0)0.28- Upper, middle or lower?52 (31.1)13 (31.7)◦ Upper69 (41.3)21 (51.2)◦ Middle22 (13.2)7 (17.1)◦ Lower76 (45.5)13 (31.7)-Peripheral, central or subpleural◦ Peripheral◦ Central◦ SubpleuralCavitation48 (28.7)5 (12.2)0.03Calcification54 (32.5)12 (29.3)0.69CAD: Coronary artery disease, CKD: Chronic kidney disease,; ILD: Interstitial Lung Disaese,ConclusionAutoantibodies seem to have impact on the characteristics of pulmonary rheumatoid nodules.

Abstract
We introduce a simple method to extract the nuclear coherent and isotope incoherent, spin incoherent, and magnetic neutron scattering cross section components from powder scattering data measured using a single neutron beam polarization direction and a position-sensitive detector with large out-of-plane coverage. The method draws inspiration from polarized small-angle neutron scattering and contrasts with conventional so-called "xyz" polarization analysis on wide-angle instruments, which requires measurements with three orthogonal polarization directions. The viability of the method is demonstrated on both simulated and experimental data for the classical "spin ice" system Ho2Ti2O7, the latter from the LET direct geometry spectrometer at the ISIS facility. The cross section components can be reproduced with good fidelity by either fitting the out-of-plane angle dependence around a Debye-Scherrer cone or grouping the data by angle and performing a matrix inversion. The limitations of the method and its practical uses are discussed.

Abstract
Abstract:
New ruthenium complexes bearing bipyridine ligands with different substituents (propyl, hexyl, isobutyl, and benzyl) were synthesized and characterized by MS, NMR, FTIR, and UV/Visible spectroscopy. Moreover, their cytotoxic, anti-carcinogenic, and anti-biofilm activities were evaluated. The electrochemical properties of the complexes have been investigated by cyclic voltammetry. The HOMO and LUMO energy levels of RuL1-RuL4 were found as (-5.45 eV)-(-5.46 eV) and (-2.98 eV)-(-3.01 eV), respectively. Cytotoxic activities of ruthenium complexes were investigated in Caco-2, HepG2, and HEK293 cells. It was found that RuL3 showed a cytotoxic effect on cancer cells without affecting non-cancerous cells at applied doses. The presence of the benzyl group may increase the cytotoxic effect of RuL3 compared to other derivatives that contain the alkyl group. The apoptotic effect of the RuL3 derivative was determined by using Arthur image-based cytometer. It found that RuL3 was induced apoptosis in Caco-2 (5-fold) and HepG2 (2-fold) cancer cells, respectively. All ruthenium complexes inhibited Staphylococcus aureus ATCC 29213 biofilm, but RuL3 had a more pronounced effect. Moreover, RuL3 had biofilm inhibition and biofilm degradation effect while RuL1 and RuL4 demonstrated only biofilm inhibition. The fluorescent microscopy analysis confirmed the antibiofilm effect of ruthenium complexes. All of these results clearly showed that RuL3 showed cytotoxic and apoptotic effects on cancer cells.

Abstract
BACKGROUND Indole-based heterocyclic compounds play important roles in pharmaceutical chemistry due to their unexpected biological and pharmacological properties. OBJECTIVE Herein, we describe novel biological properties (antioxidant, antimicrobial and anti-cancer) of 3- bromo-1-ethyl-1H-indole (BEI) structure. METHODS BEI was synthesized from 1-Methyl-2-phenylindole and N-bromosuccinimide and was characterized by using 1H and 13C NMR. Cytotoxicity was determined by MTT assay. Apoptosis analysis of BEI was determined by Arthur™ image-based Cytometer. Different methods were applied to assess the antioxidant activity of BEI. Molecular docking studies were conducted to determine the interactions of bonding between GST isozymes and BEI. RESULTS According to the antioxidant and antimicrobial activity assays, BEI compound showed reduced total antioxidant activity compared to the Trolox standard, whereas it showed moderate antimicrobial activity against Aspergillus niger and Phytophora eryhtrospora. Notably, the BEI compound demonstrated substantial selective cytotoxicity for the first time towards cancer cell lines, and there existed a significant decrease in the percentage of live cells treated with BEI, in comparison to the control ones. Interestingly, BEI exhibited a promising glutathione S-transferase isozymes inhibition. CONCLUSION The results of this study suggest that BEI seems to be a promising molecule to be used in the design of new anti-cancer agents that provide superiority to present commercial anti-cancer drugs.

Abstract
This study represents synthesis, characterization, screening of antibiofilm efficacy, and cytotoxicity of iridium bis-terpyridine complexes. The complexes were characterized by NMR, MS, FTIR, UV/Visible, and fluorescence spectroscopies. The efficacy of biofilm inhibition and eradication of iridium complexes was evaluated using a crystal violet assay test and verified by fluorescence microscopy. Cytotoxicity and apoptosis analysis of iridium complexes were determined in this study. The results of our study revealed that three iridium complexes had the potential to inhibit biofilm formation and moderate the ability to destroy pre-formed biofilm of S. aureus ATCC 29,213. 250 µM concentration of synthesized complexes showed the highest antibiofilm activity (75% for Ir1, 90% for Ir2, and 71% for Ir3). The significant inhibition obtained at 6.25 µM concentration of Ir2 and Ir3 revealed the potential of our samples. Also, Ir1 and Ir2 complexes had a good capacity to destroy pre-formed biofilm. The results clearly showed that iridium complexes have cytotoxic activity towards colon cancer (Caco-2) and liver cancer (HepG2) cell lines without affecting non-cancerous cells (HEK293) at applied doses. Moreover, tested compounds induced apoptosis in these cancer cells. All of these results showed that iridium complexes had possessed the ability to inhibit or destroy pre-formed biofilm and could be developed as an effective agent against bacterial biofilms. Moreover, these pure substances may have valuable anti-cancer activity and it should be confirmed with further studies for therapeutic effects.

Abstract
AbstractA total of 46 Staphylococcus aureus isolates from fish and ground beef were tested for the agr types, icaABCD genes, and biofilm formation at 12, 25 and 37 °C by the microtiter plate and the MTT assays. All isolates were positive for the icaABD genes, while 97.8% were positive for the icaC. All isolates produced biofilms at 37 and 25 °C, but 93.5% of them were also biofilm producers at 12 °C. There was no significant difference in biofilm formation between 25 and 37 °C using the crystal violet assay (P > 0.05). However, statistically significant differences were detected between 12 and 25 °C as well as 12 and 37 °C (P < 0.05). All isolates were significantly different in biofilm production by the MTT assay at all tested temperatures. Furthermore, a relationship between the presence of the icaABCD genes and biofilm formation was observed. The agr type I was the most prevalent (54.4%) among the isolates, followed by agr type II (41.3%) and agr type III (9.6%). In this study, the S. aureus isolates exhibited biofilm formation ability responsible for persistence of bacteria in foods, which may lead to food spoilage and human health problems.

Abstract
BACKGROUND Marine actinomycetes are among indispensable sources of natural bioactive compounds with unique antimicrobial and anti-cancer activities. OBJECTIVE Herein, it was aimed to elucidate bioactive potential of a marine-derived Streptomyces ovatisporus S4702T, isolated previously. METHODS Streptomyces ovatisporus S4702T was cultured in N-Z Amine broth and extraction was carried out using different organic solvents. Bioassay guided purification was followed by chemical characterization using NMR and LC-MS/MS. The compound was then evaluated for its antibacterial, antioxidant and cytotoxic activities. RESULTS Etyl acetate extracts gave the highest antibacterial activity and chemical characterization of this extract indicated the formula as C15H29O5N3 and the corresponding possible molecular structure as 4H-chromen-4-one derivative. It was found highly potent against Bacillus subtilis ATCC 6633 (MIC: 0.25 µg ml-1) and Micrococcus luteus ATCC 9341 (MBC: 0.5 µg ml-1). It has no remarkable antioxidant activity, but higher EC50 value and less cytotoxicity against normal cells. The EC50 values of this chromen derivative were found as 9.68 µg ml-1 for human colon carcinoma, 9.93 µg ml-1 for human prostate adenocarcinoma and 25.5 µg ml-1 for human embryonic kidney cells. CONCLUSION Overall, the presented 4H-chromen-4-one derivative is a remarkable bioactive compound with potent antibacterial and cytotoxic activity. With its high bioactive potential, it is proposed as a good candidate in medicine.

Abstract
A molecular hybridization of natural products is a new concept in drug discovery and having critical roles to design new molecules with improved biological properties. Hybrid molecules display higher biological activities when compared to the parent drugs. In the present study, two natural products (thymol and artemisinin (ART)) are used for the synthesis of new hybrid thymol-artemisinin. After characterization, the cytotoxic activity of ART-thymol was tested against different cancer cell lines and non-cancerous human cell line. ART-Thymol show the cytotoxic effect with EC50 values 70,96μM for HepG2, 97,31μM for LnCap, 6,03μM for Caco-2, 77,98μM for HeLa and 62,28μM for HEK293 cells, respectively. Moreover, ART-Thymol was checked for drug-likeness, and the kinase inhibitory activity. ART-Thymol is investigated by using molecular docking. The results of qPCR was indicated CDK2 and P38 were inhibited by ART-Thymol. These results improved that thymol-artemisinin may be new candidates as an anticancer agents.

Abstract
Colistin methanesulfonate (CMS), a clinical form of colistin, is widely used as a last-line treatment for multidrug-resistant (MDR) gram-negative bacterial infections in critically ill patients presenting a considerably high mortality rate. However, nephrotoxicity is considered to be a critical adverse effect that limits CMS's clinical use. Alpha-lipoic acid (ALA) is a strong antioxidant that is effective in preventing nephrotoxicity in many models. The aim of this study was to investigate ALA's ability to protect against nephrotoxicity induced by colistin in rats. Male Wistar albino rats were randomly divided into four groups. Group 1 was the control group (Control; n = 6), in which isotonic saline was administered to the rats. Group 2 was the ALA group (ALA; n = 6) in which rats received 100 mg/kg ALA. Groups 3 was the CMS (CMS; n = 7) in which 450.000 IU/kg/day of CMS was administered to the rats. Groups 4 was the CMS + ALA group (n = 6), in which rats were injected with 100 mg/kg of ALA 30 min before administration of CMS. All injections were performed intraperitoneally at 1, 4, 7, and 10 days. Urine was collected by using a metabolic cage for 24 h after each administration. The rats were euthanized under ether anesthesia after 24 h of the last administration. Blood and kidney samples then were collected for histological and biochemical analysis. ALA pretreatment could reverse the effects of colistin-induced nephrotoxicity, partly through its suppressing effect on Nox4 and caspase-3, which in turn results in its antioxidant and antiapoptotic effect. Therefore, ALA may be an effective strategy for the management of colistin nephrotoxicity.

Abstract
Iron has been implicated in oxidative tissue injury owing to its ability to generate reactive oxygen species (ROS). We investigated the reno-protective effects of alpha lipoic acid (ALA) by investigating its effects on the kidney isoform of NADPH oxidase (Nox4) and the specific signaling pathways, p38 MAPK and PI3K/Akt, which participate in apoptosis and survival, respectively. We established four groups of seven rats: control, 100 mg/kg ALA, 80 mg/kg iron sucrose (IS) and IS + ALA. IS and ALA were injected intravenously and rats were sacrificied after 6 h. The mRNA expression of the subunits of NADPH oxidase, Nox4 and p22phox; tumor necrosis factor-alpha (TNF-α); and kidney injury molecule-1 (KIM-1) were measured using quantitative real time polymerase chain reaction (qRT-PCR). Active caspase-3 protein expression was evaluated by immunostaining. Also, p38 MAPK and PI3K/Akt signaling pathways were analyzed using western blot. ALA suppressed the mRNA expression of Nox4, p22phox, TNF-α and KIM-1. Active caspase-3 protein expression induced by IS was decreased by ALA. ALA also suppressed p38 MAPK and activated the PI3K/Akt signaling pathway following IS administration. We found that ALA may be an effective strategy for preventing oxidative acute kidney injury caused by IS.

Abstract
Abstract
Background
Mental health literacy (MHL) is critical to reduce health inequality and for raising awareness and early recognition of mental illnesses. This study among students and teachers in Istanbul, Turkey, aimed to (1) determine the knowledge levels towards mental illnesses, (2) identify barriers to help-seeking behaviors and (3) assess stigmatizing attitudes towards mental illnesses.
Methodology
A cross-sectional, descriptive study design was used, and 810 high school students and 241 teachers were included in our study between Mar-Jul 2019. Data was collected through the Mental Health Literacy Questionnaire and the Beliefs towards Mental Illness Scale.
Results
Students' recognition percentages of depression, schizophrenia and social phobia vignettes were found to be 27.5%, 47.7% and 6.2%, respectively. Teachers' were found to be 46.5%, 42.7% and 26.1%, respectively. A statistically significant relationship was found between students' correct recognition of vignettes and gender, age group, mother education levels, and father education levels (p < 0,005). Female sex, older age, and having a parent with higher level of education were more likely to correct identify the vignettes. Among teachers, a significant relationship was found between correct recognition of vignettes and gender (p < 0,005). Females were more likely to correct identify the vignettes. Regarding the BMI subscales, students' average score was 21,6±9,8 for “poor social and interpersonal skills and incurability”, 19,9±6,9 for “dangerousness”, 1,5±2,3 for “shame” and 42,9±16,2 for total scale and the teachers' average scores were 23,6±10,1, 21,3±6,6, 1,2±1,7 and 46,2±16,6 in the same order.
Conclusions
The findings show that efforts are needed among both pupils and teachers in order to encourage help seeking behavior and to increase the belief that the solution of mental health problems is possible. Strengthening accessible mental health services and reducing stigma towards mental illnesses are also crucial.

Abstract
The hepatitis C virus (HCV) is a blood-borne pathogen that causes acute or chronic infection of the liver, sometimes leading to serious liver damage and fatality. The objective of this study was to evaluate HCV prevalence in patients attending the Regional Training and Research Hospital for Medical Examination and Surgery in Samsun Province of Turkey between 2014 and 2017. Blood specimens taken from 152 596 patients were screened for HCV infection by using the anti-HCV assay. Seropositive samples were subjected to polymerase chain reaction (PCR) testing in order to determine whether the HCV infection was active. Genotyping was then performed. Overall, HCV seropositivity and active HCV infection were 2.76% and 2.05%, respectively. Foreign nationals accounted for 5.61% of the seropositive samples and 1.37% of active HCV infective samples. We further report that 2017 was the year with the highest seroprevalence which was 3.64%. HCV genotype 1 was the most common genotype detected in residents of Samsun Province at 89.86%, followed by Genotype 3 at 4.54%. This study provides important information on the levels of HCV infection in the Samsun region of Turkey. The data indicate that there was a rising trend of HCV infection between 2014 and 2017.

Abstract
OBJECTIVES The aim of this clinical study was to evaluate the clinical performance of Class II restorations of a high-viscosity glass ionomer material, of a bulk-fill composite resin, and of a microhybrid composite resin. METHODS AND MATERIALS One hundred nine Class II restorations were performed in 54 patients using three different restorative materials: Charisma Smart Composite (CSC; a conventional composite resin), Filtek Bulk Fill Posterior Restorative (FBF; a high-viscosity bulk-fill composite), and Equia Forte Fil (EF; a high-viscosity glass ionomer). Single Bond Universal adhesive (3M ESPE, Neuss, Germany) was used for both conventional and bulk-fill composite resin restorations. The restorations were evaluated using modified US Public Health Service criteria in terms of retention, color match, marginal discoloration, anatomic form, contact point, marginal adaptation, secondary caries, postoperative sensitivity, and surface texture. The data were analyzed using the chi-square, Fisher, and McNemar tests. RESULTS Eighty-four restorations were evaluated at two-year recalls. There were clinically acceptable changes in composite resin restorations (FBF and CSC). In addition, no statistically significant difference was observed between the clinical performances of these materials in terms of all criteria (p>0.05). However, there was a statistically significant difference between the EF group and the FBF and CSC groups in all parameters except for marginal discoloration, secondary caries, and postoperative sensitivity (p<0.05). CONCLUSIONS The tested bulk-fill and conventional composite resins showed acceptable clinical performance in Class II cavities. However, if EF is to be used for Class II restoration, its use should be carefully considered.

Abstract
Bovine parainfluenza 3 virus (BPI3V)is one of the most important respiratory pathogens and a leading cause of serious respiratory illnesses in cattle, both independent of and in connection with other pathogens involved in the bovine respiratory disease complex (BRDC). In this study, we aimed to identify the historical circulation of genotype C bovine BPI3V (BPI3Vc) in Turkey using the archival serum samples of domestic ruminants that had been collected from six provinces of northern Anatolia in Turkey between 2009-2010. A total of 896 sera from cattle (n=442), sheep (n=330), and goats (n=124) were randomly selected and screened with a virus neutralization test in order to detect antibodies for BPI3Vc. The overall seropositivity rate was 21.09%, with seropositivity rates for cattle, sheep, and goats of 21.04%, 20.00%, and 24.19%, respectively. Neutralizing antibody titers for selected samples ranged between 1/4 to 1/512. This study represents the first serological study conducted using the first BPI3V isolate of Turkey.

Abstract
Aim We report the results of the surgical treatment of symptomatic urachal cysts. Materials and Methods The medical records of patients who underwent urachal cyst excision between 2012 and 2017 were reviewed retrospectively at our hospital. The age, sex, presenting complaint, method of diagnosis, average cyst diameter, surgical procedure, and postoperative complications of each patient were recorded. Results Twenty-seven patients who had urachal cyst were included in this study; 5 out of 27 patients were treated conservatively and the rest of patients were treated surgically, made up of 16 males (72%) and 6 females (28%). The average age of the patients was 7 years (range: 1-17). The most common reason for referral was abdominal pain in 12 patients (54%), discharge in 6 patients (28%), fever in 2 patients (9%), and an abdominal mass in 2 patients (9%). An ultrasound scan was performed in all patients as an initial imaging study. The average cyst diameter was 1.5 cm (range: 1-6 cm). Laparotomy was performed in 16 patients, with 6 patients undergoing laparoscopic excision. Postoperative wound infection developed in two patients. Conclusions Patients with urachal cysts may be managed conservatively initially. However, patients who do not show any clinical and radiological signs of regression, or those who have large cysts, should undergo surgical excision through laparotomy or a laparoscopic approach.

Abstract
Cell-type specific gene expression programs are tightly linked to epigenetic modifications on DNA and histone proteins. Here, we used a novel CRISPR-based epigenome editing approach to control gene expression spatially and temporally. We show that targeting dCas9-p300 complex to distal non-regulatory genomic regions reprograms the chromatin state of these regions into enhancer-like elements. Notably, through controlling the spatial distance of these induced enhancers (i-Enhancer) to the promoter, the gene expression amplitude can be tightly regulated. To better control the temporal persistence of induced gene expression, we integrated the auxin-inducible degron technology with CRISPR tools. This approach allows rapid depletion of the dCas9-fused epigenome modifier complex from the target site and enables temporal control over gene expression regulation. Using this tool, we investigated the temporal persistence of a locally edited epigenetic mark and its functional consequences. The tools and approaches presented here will allow novel insights into the mechanism of epigenetic memory and gene regulation from distal regulatory sites.

Abstract
BACKGROUND AND STUDY AIMS Although several factors are thought to be responsible for the development of colonic diverticulosis (CD), the underlying pathogenesis is still obscure and needs clarification. The aim of this study was to determine the prevalence, location and clinical features of CD and especially to detect whether there is an association between CD and postures during defecation. PATIENTS AND METHODS This prospective study enrolled 757 patients. The subjects were divided into two groups as a diverticulosis group (D group, n:95) and non-diverticulosis group (non-D group, n:662). RESULTS The median patient age was 54.9±13.2 years. CD frequency was 12.5% (n:95). The most commonly involved part of the colon was the sigmoid colon (56.8%). Diverticula location was on the left in 45.3% (n:43), on the right in 24.2% (n:23) and on both sides of the colon in 30.5% (n:29). Patients in the D group were older (p<0.001) and were predominantly female (p:0.04). The frequency of sitting during defecation (Western type toilet) was higher in the D group compared to the non-D group (72.2% vs 53.5%; p:0.007). The use-time of a Western-type toilet was longer in the D group compared to the non-D group (p:0.04). In multivariable logistic regression analysis, age and toilet type were independent risk factors for the development of diverticulosis. CONCLUSION Sitting during defecation seems to increase the risk of CD.

Abstract
ETHNOPHARMACOLOGICAL IMPORTANCE Decoction and infusion prepared from aerial parts of Lavandula stoechas L. (L. stoechas) have been traditionally used as remedy against several components of metabolic syndrome (MetS) and associated disorders including type II diabetes and cardiovascular diseases by Anatolian people. AIM OF THE STUDY The aim is to elucidate the potential ameliorative effects of L. stoechas aqueous extracts on insulin resistance and inflammation models through multitarget in vitro approaches and also to elucidate mechanism of action by analyzing transcriptional and metabolic responses. MATERIALS AND METHODS An aqueous extract was prepared and fractionated to give rise to ethyl acetate (EE) and butanol (BE) extracts. The anti-insulin resistance effects of BE and EE were evaluated on palmitate induced insulin resistance model of H4IIE, C2C12 and 3T3L1 cells by using several metabolic parameters. Specifically, whole genome transcriptome analysis was performed by using microarray over 55.000 genes in control, insulin resistant and EE (25 µg/mL) treated insulin resistant H4IIE cells. Anti-inflammatory effects of both extracts were analyzed in LPS-stimulated RAW264.7 macrophages. RESULTS Both EE and BE at low doses (25-50 µg/mL) significantly decreased hepatic gluconeogenesis in H4IIE cell line by suppressing the expression of PEPCK and G6Pase. In C2C12 myotubes, both extracts increased the insulin stimulated glucose uptake more effectively than metformin. Both extracts decreased the isoproterenol induced lipolysis in 3T3L1 cell line. Moreover, they also effectively increased the expression of lipoprotein lipase protein level in insulin resistant myotubes at low doses. EE increased the protein level of PPARγ and stimulated the activation AKT in insulin resistant H4IIE and C2C12 cell lines. The results obtained from biochemical assays, mRNA/protein studies and whole genome transcriptome analyses were found to be complementary and provided support for the hypothesis that EE might be biologically active against insulin resistance and act through the inhibition of liver gluconeogenesis and AKT activation. Besides, LPS induced inflammation in RAW264.7 macrophages was mainly inhibited by EE through suppression of iNOS/NO signaling, IL1β and COX-2 genes. HPLC-TOF/MS analysis of EE of L. stoechas mainly resulted in caffeic acid, apigenin, luteolin, rosmarinic acid and its methyl ester, 4-hydroxybenzoic acid, vanillic acid, ferrulic acid and salicylic acid. CONCLUSION Data suggest that EE of L. stoechas contains phytochemicals that can be effective in the treatment/prevention of insulin resistance and inflammation. These results validate the traditional use of L. stoechas in Anatolia against several metabolic disorders including metabolic syndrome.

Abstract
INTRODUCTION Child abuse is a serious public problem. Signs of abuse are often present in the oro-facial region and dentists are in a strategic position to recognise and report suspected cases. The aim of this study was to investigate dental students' knowledge about and attitudes towards child abuse. MATERIAL AND METHODS This study was performed at the Faculty of Dentistry of the Ondokuz Mayis University. The data were collected through a self-report questionnaire administered to dental students (137 female/111 male) in three different dental classes (third, fourth and fifth study years) and grouped by considering those students who have been training in the school year of 2013. The definition of physical and social indicators of abuse, awareness regarding legal and ethical responsibilities, students' experience and requests made by students were evaluated by the students' response to questions put in the questionnaire. Descriptive statistics and chi-square tests were performed to analyse the questionnaire data. RESULTS The questionnaire completion rate was 100%. About 67.74% of the third year, 40.71% of the fourth year and 16.67% of the fifth year believed that they could detect child abuse cases. However, results indicated a major lack of knowledge of social indicators, signs of physical abuse and reporting procedure amongst all respondents. The assessment of the total correct answers exhibited significant differences amongst third-, fourth- and fifth-year students' answers. Fifth-year students had the highest rate of correct responses (P < 0.05). Most students wanted to receive more knowledge about this topic. CONCLUSION Dental students in Turkey are not sufficiently prepared for their role in diagnosing suspected cases of child abuse.

Abstract
OBJECTIVES In ankylosing spondylitis (AS) patients, cardiac and vascular involvement may manifest as atherosclerosis and coronary artery disease. Systemic inflammation, oxidative stress, increased low-density lipoprotein (LDL) cholesterol and decreased high-density lipoprotein (HDL) cholesterol constitute a significant risk for atherosclerosis. This study investigated the relationship between carotid intima-media thickness (CIMT), LDL/HDL ratio, total oxidant status (TOS; an indicator of oxidative stress) and ischemic modified albumin (IMA; an ischemic marker in AS patients). PATIENTS AND METHODS Sixty AS patients were diagnosed using the Modified New York Criteria; 54 age- and gender-matched participants were included as controls. CIMT, LDL/HDL ratio, TOS and IMA were measured using the most appropriate methods. RESULTS IMA was higher in AS patients compared to controls (p < 0.0001). TOS was also increased in AS patients (p = 0.005); as was CIMT (p < 0.0001). The LDL/HDL ratio was also greater in AS patients compared to controls (p = 0.047). A positive correlation was found between CIMT and LDL/HDL ratio among AS patients. CONCLUSION Elevated CIMT, IMA and TOS levels suggest an increased risk of atherosclerotic heart disease in AS patients. The LDL/HDL ratio was higher in AS patients compared to controls, and there was a correlation between LDL/HDL ratio and CIMT, albeit statistically weak. Therefore, the LDL/HDL ratio is not a reliable marker to predict atherosclerotic heart disease in AS patients.

Abstract
Dysregulated expression of matrix metalloproteinases (MMPs) is closely associated with the pathogenesis of renal ischemia/reperfusion injury (I/R). The production of excessive reactive oxygen species (ROS) causes tissue damage. Increased ROS production causes activation of p38 mitogen-activated protein kinase (MAPK) signaling, which participates in gene regulation of MMPs, especially MMP-2 and MMP-9 (gelatinases). Taurine (2-aminoethanesulfonic acid) in mammalian cells functions in bile acid conjugation, maintenance of calcium homeostasis, osmoregulation, membrane stabilization, and antioxidation, antiinflammatory, and antiapoptotic action. We investigated the effects of taurine and the possible role of p38 MAPK signaling on regulation of MMP-2 and MMP-9 in a renal I/R injury model in rats. Rats were divided into three groups: sham, I/R, and I/R + taurine treated. After a right nephrectomy, I/R was induced by clamping the left renal pedicle for 1 h followed by 6 h reperfusion. Taurine was administered 45 min prior to induction of ischemia. Renal function was assessed by serum creatinine and blood urea nitrogen (BUN) levels. Tubule injury and structural changes were evaluated by light microscopy. Malondialdehyde (MDA) levels were analyzed by high performance liquid chromatography (HPLC). Superoxide dismutase (SOD) activity levels were measured using a colorimetric kit. mRNA expression of MMP-2 and MMP-9 was determined by real-time polymerase chain reaction. MMP-2 and MMP-9 activities were measured using a fluorimetric kit. Phosphorylated p38 (p-p38) and total p38 MAPK protein expressions were evaluated by western blot. Taurine pretreatment significantly attenuated renal dysfunction and histologic damage, such as renal tubule dilation and loss of brush borders. The pretreatment also decreased the MDA level and attenuated the reduction of SOD activity in the kidney during I/R. Taurine pretreatment also decreased significantly both MMP-2 and MMP-9 mRNA expression and MMP-9 activity induced by I/R. In addition, the activity of p38 MAPK signaling was down-regulated significantly by taurine administration. Inhibition of MMP-2 and MMP-9 expression and MMP-9 activity caused by taurine may be associated with suppression of p38 MAPK activation during I/R induced renal injury in rats. Therefore, taurine administration may prove to be a strategy for attenuating renal I/R injury.

Abstract
A total of 120 samples including 40 freshwaterfish(Oncorhynchus mykiss), 40 seawater fish (Sparus aurata) and 40 ground beef samples were examined for the presence of Staphylococcus aureus. The isolates were identified using biochemical tests and a PCR for the species-specific fragment (Sa442) and thermonuclease gene (nucA). The presence of staphylococcal enterotoxin genes (sea, seb, sec, sed and see), toxin genes (eta, etb, tsst), methicillin resistance gene (mecA) and some phenotypic virulence factors was also tested. Genotypic characterization of the isolates was analyzed by PCR-RFLP of the coa gene. Overall, 36 (30%) meat samples were contaminated with S. aureus. Of the 36 isolates, 3 (8.3%) were found to be positive for enterotoxin genes. Only 1 isolate (5.9%) from ground beef had the sea gene. In addition, 1 (12.5%) of the freshwater fish and 1 (9.1%) of the seawater fish carried both the sea and sed genes. The presence of seb, sec, see, eta, etb and tsst was not detected among the isolates of S. aureus. The amplified coa gene revealed five different clusters. Seven and six distinct RFLP patterns were obtained with AluI and HaeIII digestion, respectively. All isolates were found to be positive for slime, hemolytic and DNase activity while 41.7% of them were beta-lactamase positive. The presence of methicillin resistance was neither detected by PCR nor the disk diffusion method. A total of 94.4% of the isolates were resistant to at least one antimicrobial while 44.4% of them were resistant to at least two or more antimicrobials.

Abstract
OBJECTIVES Behcet's disease (BD) is a systemic vasculitis characterized by cardiovascular complications. Early diagnosis of these complications can reduce morbidity and mortality. Carotid artery intima-media thickness (cIMT) and the logarithmic value of triglyceride to high density lipoprotein ratio (atherogenic index of plasma, AIP) are good markers of atherosclerosis. The purpose of this study was to investigate whether AIP is a predictive marker of subclinical atherosclerosis in BD patients. PATIENTS AND METHODS A total of 84 BD patients (60 male, 24 female) and 84 healthy control individuals (58 male, 26 female) were included in this study. cIMT measurements were made, and AIP values were calculated. RESULTS cIMT (p < 0.001) and AIP (p < 0.001) values of the BD patients were higher than those of the control group. A strong independent relationship was found between the AIP value and cIMT (β = 0.232, p = 0.018). In the subgroup analysis, the cIMT and AIP values of male BD patients were higher than those of female BD patients. CONCLUSION Increased AIP and cIMT values can be a good marker for subclinical atherosclerosis in BD patients, especially in male BD patients.

Abstract
Objective Erythropoietin (EPO) improves cardiac function and induces neovascularisation in post-myocardial infarction heart failure. The aim of this study was to analyse the association between the serum erythropoietin level and coronary collateral development in patients with coronary artery disease and chronic total occlusion. Methods A total of 168 patients consisting of 117 with coronary artery disease (CAD, (62 with chronic total occlusion (CTO), 55 without CTO)) and 51 with healthy coronary arteries were included in the study. The patients were assigned as coronary artery disease without CTO (group 0), CAD with CTO (group 1: poor collateral development, group 2: good collateral development) and normal coronary arteries (group 3). Results There was a significant positive correlation between serum EPO levels and the Rentrop scores in angiography (r = 0.243, p = 0.001). Similarly, a positive correlation was found between serum EPO levels and the Syntax scores (r = 0.253, p = 0.001). Echocardiography revealed a negative correlation between serum EPO levels and the cardiac ejection fraction (r = −0.210, p = 0.006). Conclusions Serum EPO is a useful biomarker for coronary collateral development in patients with CTO.
