Abstract
Sustainable treatment of aqueous deficient dry eye (ADDE) represents an unmet medical need and therefore requires new curative and regenerative approaches based on appropriatein vitromodels. Tissue specific hydrogels retain the individual biochemical composition of the extracellular matrix and thus promote the inherent cell´s physiological function. Hence, we created a decellularized lacrimal gland (LG) hydrogel (dLG-HG) meeting the requirements for a bioink as the basis of a LG model with potential forin vitroADDE studies. Varying hydrolysis durations were compared to obtain dLG-HG with best possible physical and ultrastructural properties while preserving the original biochemical composition. A particular focus was placed on dLG-HG´s impact on viability and functionality of LG associated cell types with relevance for a futurein vitromodel in comparison to the unspecific single component hydrogel collagen type-I (Col) and the common cell culture substrate Matrigel. Proliferation of LG epithelial cells (EpC), LG mesenchymal stem cells, and endothelial cells cultured on dLG-HG was enhanced compared to culture on Matrigel. Most importantly with respect to a functionalin vitromodel, the secretion capacity of EpC cultured on dLG-HG was higher than that of EpC cultured on Col or Matrigel. In addition to these promising cell related properties, a rapid matrix metalloproteinase-dependent biodegradation was observed, which on the one hand suggests a lively cell-matrix interaction, but on the other hand limits the cultivation period. Concluding, dLG-HG possesses decisive properties for the tissue engineering of a LGin vitromodel such as cytocompatibility and promotion of secretion, making it superior to unspecific cell culture substrates. However, deceleration of biodegradation should be addressed in future experiments.

Abstract
BACKGROUND Heterogeneity in type 2 diabetes can be represented by a tree-like graph structure by use of reversed graph-embedded dimensionality reduction. We aimed to examine whether this approach can be used to stratify key pathophysiological components and diabetes-related complications during longitudinal follow-up of individuals with recent-onset type 2 diabetes. METHODS For this cohort analysis, 927 participants aged 18-69 years from the German Diabetes Study (GDS) with recent-onset type 2 diabetes were mapped onto a previously developed two-dimensional tree based on nine simple clinical and laboratory variables, residualised for age and sex. Insulin sensitivity was assessed by a hyperinsulinaemic-euglycaemic clamp, insulin secretion was assessed by intravenous glucose tolerance test, hepatic lipid content was assessed by 1 H magnetic resonance spectroscopy, serum interleukin (IL)-6 and IL-18 were assessed by ELISA, and peripheral and autonomic neuropathy were assessed by functional and clinical measures. Participants were followed up for up to 16 years. We also investigated heart failure and all-cause mortality in 794 individuals with type 2 diabetes undergoing invasive coronary diagnostics from the Ludwigshafen Risk and Cardiovascular Health (LURIC) cohort. FINDINGS There were gradients of clamp-measured insulin sensitivity (both dimensions: p<0·0001) and insulin secretion (pdim1<0·0001, pdim2=0·00097) across the tree. Individuals in the region with the lowest insulin sensitivity had the highest hepatic lipid content (n=205, pdim1<0·0001, pdim2=0·037), pro-inflammatory biomarkers (IL-6: n=348, pdim1<0·0001, pdim2=0·013; IL-18: n=350, pdim1<0·0001, pdim2=0·38), and elevated cardiovascular risk (nevents=143, pdim1=0·14, pdim2<0·00081), whereas individuals positioned in the branch with the lowest insulin secretion were more prone to require insulin therapy (nevents=85, pdim1=0·032, pdim2=0·12) and had the highest risk of diabetic sensorimotor polyneuropathy (nevents=184, pdim1=0·012, pdim2=0·044) and cardiac autonomic neuropathy (nevents=118, pdim1=0·0094, pdim2=0·06). In the LURIC cohort, all-cause mortality was highest in the tree branch showing insulin resistance (nevents=488, pdim1=0·12, pdim2=0·0032). Significant gradients differentiated individuals having heart failure with preserved ejection fraction from those who had heart failure with reduced ejection fraction. INTERPRETATION These data define the pathophysiological underpinnings of the tree structure, which has the potential to stratify diabetes-related complications on the basis of routinely available variables and thereby expand the toolbox of precision diabetes diagnosis.

Abstract
OBJECTIVE Prostate cancer diagnosis and treatment are increasing in current public healthcare programs. An improved resolution multiparametric magnetic resonance imaging (MRI) has shown the potential to enhance the detection and differentiation of this medical condition. In this study, MR perfusion parameters were investigated in different ages and diseases to differentiate clinically significant prostate cancer. PATIENTS AND METHODS From January 2017 to December 2022, 72 consecutive patients, who had undergone multiparametric MR imaging were enrolled in this study. Four different patient groups were formed: (1) those with prostate cancer, (2) those with prostatitis, (3) those with benign prostate hyperplasia (BPH), and (4) a control group. Quantitative dynamic contrast-enhanced (DCE)-MRI pharmacokinetic parameters included Ktrans, Kep, Ve, and iAUG. Different measurements were obtained from both the peripheral and transitional zones (PZ and TZ, respectively). Means values were compared between groups based on a univariate analysis. RESULTS Ktrans and Kep values in the PZ were found to be statistically significantly lower in the control group (p = 0. 003 and p = 0. 011, respectively). It was seen that Ktrans and Ve measurements obtained from PZ had a statistically significant determinant in detecting malignancy (p = 0. 013 and p = 0. 036, respectively). It was seen that Ktrans, Ve, and iAUG obtained from the TZ showed a statistically significant difference in prostate cancer (p = 0.025, p = 0.005, and p = 0. 011, respectively) in contrast to other cases. Peripheral Ve values were statistically significantly lower than those measured Ve values from the TZ in prostate cancer cases (p = 0.002) in contrast to the other cases. CONCLUSIONS Quantitative DCE-MRI parameters may vary according to age, disease, and zonal anatomy. These differences may contribute to the diagnosis of clinically relevant prostate cancer.

Abstract
OBJECTIVE We aimed to compare the risk of developing complications between patients who had long-term COVID-19 and those who did not. PATIENTS AND METHODS This is a retrospective study involving a total of 265 patients who had undergone total knee arthroplasty surgery. A cohort of patients (Group 1) who had been diagnosed with COVID-19 six months prior to total knee arthroplasty was established and matched to a cohort of patients who had never been diagnosed with COVID-19 (Group 2). Demographic information such as age and gender, underlying diseases, postoperative complications (surgical site infection, wound problem, periprosthetic fracture, deep vein thrombosis, pulmonary thromboembolism, hematoma, pneumonia, urinary tract infection) and exitus were recorded. RESULTS Of the 265 patients, 217 (81.9%) were females and 48 (18.1%) were males. 41 of these patients (15.5%) previously had COVID-19 (Group 1). The number of people who did not have COVID-19 was 224 (84.5%) (Group 2). There was no difference between group 1 and group 2 in terms of complications. CONCLUSIONS This study found that the rate of complications, including deep vein thrombosis, in patients who had COVID-19 six months before total knee arthroplasty was not higher than those who did not.

Abstract
Background In endodontic treatment, the aim is to completely determine, shape, and fill all root canals in a three-dimensional way. Missed canals lead to treatment failure. In mandibular molars, there may be an extra canal called the middle mesial canal between the mesiobuccal and mesiolingual canals. Aim The aim of this study was to evaluate the prevalence of missed middle mesial canals in root canal-treated mandibular molar teeth. Materials and Methods In this study, cone-beam computed tomography (CBCT) images of 1054 patients were analyzed. We identified 121 endodontically treated mandibular molars and evaluated the prevalence of missed canals. Results Although 33.05% of the root canal-treated teeth did not have a middle mesial canal, this canal was detected in the other 66.94%; 97.53% of teeth with a middle mesial canal could not be detected by clinicians. Conclusion Clinicians performing endodontic treatment of mandibular molar teeth should not ignore the presence of the middle mesial canal. Thus, it is very important for clinicians to have sufficient information about the localization, morphology, and variations of the middle mesial canal.

Abstract
OBJECTIVE This study aimed to evaluate maternal serum Netrin-1 and Netrin-4 levels in pregnancies complicated with placenta accreta spectrum. PATIENTS AND METHODS This cross-sectional study enrolled 49 pregnant women with the diagnosis of placenta accreta spectrum as the study group. Gestational age-matched 30 uncomplicated pregnant women with prior cesarean delivery and normal placentation were randomly selected as the control group. Maternal serum Netrin-1 and Netrin-4 levels were measured between weeks 34 and 36 of gestation. RESULTS There was no significant difference between the groups in terms of demographic characteristics. Maternal serum Netrin-1 levels were significantly lower in placenta accreta spectrum cases compared with those in the control group (p=0.038). There was no significant difference between the groups in terms of maternal serum Netrin-4 levels (p>0.05). There was a significant negative correlation between maternal serum Netrin-1 levels and the number of prior cesarean deliveries (r=-0.313, p=0.005). CONCLUSIONS The observed decrease in maternal serum Netrin-1 levels in placenta accreta spectrum cases associated with increased angiogenesis might be one of the factors involved in the pathophysiology of this disease.

Abstract
INTRODUCTION This study aimed to evaluate the possible effects of maxillary molar distalization on maxillary sinus mucosa thickness and sinus volume in 3-dimensions. METHODS The study was conducted with 46 patients: 73.9% (n = 34) females and 26.1% (n = 12) males. The patients had a mean age of 27.89 ± 6.62 years, ranging from 18 to 45 years. The study included patients who were admitted to the Faculty of Dentistry at Van Yüzüncü Yıl University between 2010 and 2021 and underwent cone-beam computed tomography (CBCT) before and after orthodontic treatment for various reasons. The CBCT scans of patients were divided into 2 groups: the first group underwent orthodontic treatment and maxillary molar distalization with Class II elastic, whereas the second group consisted of patients who did not get orthodontic treatment (control). In CBCTs, sinus mucosa thickness was measured on the anterior, posterior, medial, lateral, superior, and inferior walls of the maxillary right and left sinuses. Three-dimensional volume calculations were made using CBCT images taken before and after the treatment of both orthodontic treatment patients and control patients. Statistical significance was set at P <0.05. RESULTS The orthodontic treatment group had a mean distalization of 2.86 ± 0.27 mm. The mean distalization time was 8.01 ± 0.64 months. When the differences between the pretreatment and posttreatment CBCT scans were examined in terms of sinus mucosa thickness in the anterior, posterior, medial, lateral, and superior walls of the right and left sinuses, there was no statistically significant difference between treatment and control groups (P >0.05). The change in sinus mucosa thickness in the right and left sinus inferior wall from T1 to T2 was significantly higher in the control group than treatment group (P <0.05). In addition, the increase in maxillary sinus volume was statistically significantly higher in the treatment group than in the control group (P <0.05). CONCLUSIONS We observed that maxillary molar distalization caused an increase in maxillary sinus volume. The change in sinus mucosa thickness in the right and left sinus inferior wall was lower in the maxillary molar distalization group.

Abstract
BACKGROUND "Spaceflight associated neuro-ocular syndrome" (SANS) represents a challenging health condition in modern space medicine. Forty-eight percent of astronauts are diagnosed with SANS after long-term space missions. The pathophysiological mechanism seems to be multifactorial, and yet remains unknown. In this proof-of-concept study we plan to investigate retinal microcirculatory changes in weightlessness and aim to identify their role in the development of SANS. METHODS AND DESIGN Healthy individuals will take part in a parabolic flight campaign, which recreates fractioned total weightlessness periods. The airplane is specifically equipped, and designed for the execution of parabolic flight maneuvers and scientific research in microgravity. Retinal microcirculation will be assessed with a modified fundus camera, which allows dynamic vessel analysis. We will additionally measure intra-ocular pressure and hemodynamic changes during each phase of the flight. Blood samples will be analyzed at baseline, one hour and 24 hours after exposure to weightlessness. CONCLUSIONS This pilot study aims to investigate the feasibility of retinal microcirculation assessment during varying gravity. Results of this study may generate insights whether venous stasis in the eye, surrogated by the dilatation of retinal vessels and increase in intraocular pressure as signs of venous insufficiency, may potentially contribute to the development of SANS.

Abstract
New dyes were developed and produced utilizing distinct electron donors (phenothiazine and dibenzofuran), a π-spacer, and an electron acceptor of cyanoacetohydrazide, and their structures were studied using FT-IR and NMR spectroscopy. Following the synthesis of dye molecules, the photophysical and photovoltaic characteristics were investigated using experimental and theoretical methods. The photosensitizers have been exposed to electrochemical and optical property experiments in order to study their absorption performance and also molecular orbital energies. The monochromatic optical conversion efficiency of (Z)-N-((5-(10H-phenothiazin-2-yl)furan-2-yl)methylene)-2-cyanoacetohydrazide (PFCH) was found higher than that of (Z)-2-cyano-N'-((5-(dibenzo[b,d]furan-4-yl)furan-2-yl)methylene)acetohydrazide (BFCH), with IPCEs of 58 and 64% for BFCH and PFCH, respectively. According to the photosensitizer molecular energy level diagram, the studied dye molecules have strong thermodynamically advantageous ground and excited-state oxidation potentials for electron injection into the conduction band of titanium oxide. It was observed that the ability to attract electrons correlated favorably with molecular orbital energy. While density functional theory calculations were used to examine molecule geometries, vertical electronic excitations, and frontier molecular orbitals, experimental and computed results were consistent. Natural bond orbital and nonlinear optical properties were also calculated and discussed.

Abstract
AIM Patients with lipodystrophy are at high risk for chronic complications of diabetes. Recently, we have reported 18 diabetic foot ulcer episodes in 9 subjects with lipodystrophy. This current study aims to determine risk factors associated with foot ulcer development in this rare disease population. METHODS Ninety metreleptin naïve patients with diabetes registered in our national lipodystrophy database were included in this observational retrospective cohort study (9 with and 81 without foot ulcers). RESULTS Patients with lipodystrophy developing foot ulcers had longer diabetes duration (p = 0.007), longer time since lipodystrophy diagnosis (p = 0.008), and higher HbA1c levels (p = 0.041). Insulin use was more prevalent (p = 0.003). The time from diagnosis of diabetes to first foot ulcer was shorter for patients with generalized lipodystrophy compared to partial lipodystrophy (p = 0.036). Retinopathy (p < 0.001), neuropathy (p < 0.001), peripheral artery disease (p = 0.001), and kidney failure (p = 0.003) were more commonly detected in patients with foot ulcers. Patients with foot ulcers tended to have lower leptin levels (p = 0.052). Multiple logistic regression estimated significant associations between foot ulcers and generalized lipodystrophy (OR: 40.81, 95% CI: 3.31-503.93, p = 0.004), long-term diabetes (≥ 15 years; OR: 27.07, 95% CI: 2.97-246.39, p = 0.003), and decreased eGFR (OR: 13.35, 95% CI: 1.96-90.67, p = 0.008). CONCLUSIONS Our study identified several clinical factors associated with foot ulceration among patients with lipodystrophy and diabetes. Preventive measures and effective treatment of metabolic consequences of lipodystrophy are essential to prevent the occurrence of foot ulcers in these high-risk individuals.

Abstract
OBJECTIVES For many years, tumor development has been viewed as a cell-autonomous process; however, today we know that the tumor microenvironment (TME) and especially cancer-associated fibroblasts (CAFs) significantly contribute to tumor progression. Caveolin-1 (Cav-1) is a scaffolding protein which is involved in several cancer-associated processes as important component of the caveolae. Our goal was to shed light on the expression of the two different isoforms of Cav-1 in normal fibroblasts (NFs) and CAFs of patients with oral squamous cell carcinoma (OSCC). MATERIALS AND METHODS Fibroblasts from normal mucosa and CAFs were isolated and propagated in vitro. Gene expression of the different Cav-1 isoforms was assessed via quantitative real-time PCR (qPCR) and supplemented by protein expression analysis. RESULTS We could show that the Cav-1β isoform is more highly expressed in NFs and CAFs compared to Cav-1α. Furthermore, the different Cav-1 isoforms tended to be differently expressed in different tumor stages. However, this trend could not be seen consistently, which is in line with the ambiguous role of Cav-1 in tumor progression described in literature. Western blotting furthermore revealed that NFs and CAFs might differ in the oligomerization profile of the Cav-1 protein. CONCLUSION These differences in expression of Cav-1 between NFs and CAFs of patients with OSCC confirm that the protein might play a role in tumor progression and is of interest for further analyses. CLINICAL RELEVANCE Our findings support a possible role of the two isoforms of Cav-1 in the malignant transformation of OSCC.

Abstract
OBJECTIVES The purpose of this study was to evaluate the effect of section thickness on volume estimations of bone defects scanned using cone beam computed tomography (CBCT). METHODS 25 bone defects were prepared on sheep mandibles and scanned using a KaVo 3D eXam (KaVo Dental, Biberach, Germany) CBCT device. Section thickness of images were reconstructed at 0.25, 0.5, and 0.75 mm to estimate the volume of these defects using the semiautomatic segmentation method. The volume averages obtained using microcomputed tomography and Archimedes' method served as reference values. The estimated volumes at each section thickness were compared with the actual volumes using the Friedman test. The accuracy of volume estimation was determined by the percentage error with respect to the reference values, and the mean absolute error (MAE) was calculated. RESULTS Volumetric values of bone defects obtained with CBCT at section thicknesses up to 0.5 mm were compatible with the actual volumes (p > 0.05). The percentage errors at section thicknesses of 0.25, 0.5, and 0.75 mm were -5.4%, -7.3%, and -13.1%, respectively. The mean absolute errors were 13.6 mm3, 15.7 mm3, and 18.2 mm3, respectively. CONCLUSIONS The section thickness values of CBCT images can be increased to a reasonable level to obtain accurate volume estimation results and save time. The semiautomatic segmentation method can be used reliably for volume estimations of bone defects.

Abstract
Crigler-Najjar syndrome is a rare disease which is associated with congenital deficiency of uridine-diphosphate-gulukronyltransferase (UDP-glucuronosyltransferase, UGT) enzyme. In the surgery of these patients, it is necessary to use an anesthetic method that causes less damage to the liver. Spinal anesthesia is a good alternative to general anesthesia in these patients. Transversus abdominis plane block is a new method for ultrasound guided abdominal wall block. It is less invasive and relatively safer than conventional regional anesthetic techniques. Our case is a 30-year-old male patient with the diagnosis of Crigler-Najjar type 2 (Arias syndrome). There was a history of gallbladder edema, multiple stones and thickened gallbladder wall. We applied Transversus abdominis plane block in addition to spinal anesthesia as primary anesthesia for our patient who underwent laparoscopic surgery. We didn't experience any postoperative complications in our patient. In conclusion, laparoscopic surgery performed under combined spinal anesthesia and transvesus abdominis plane block in a Criggler Najjar type 2 (Arias syndrome) patient may be a simple and effective technique.

Abstract
Determination of antibodies against ToRCH antigens at the beginning of pregnancy allows assessment of both the maternal immune status and the risks to an adverse pregnancy outcome. Age-standardised seroprevalences were determined in sera from 1009 women of childbearing age residing in Mexico, Brazil, Germany, Poland, Turkey or China using a multiparametric immunoblot containing antigen substrates for antibodies against Toxoplasma gondii, rubella virus, cytomegalovirus (CMV), herpes simplex viruses (HSV-1, HSV-2), Bordetella pertussis, Chlamydia trachomatis, parvovirus B19, Treponema pallidum and varicella zoster virus (VZV). Seroprevalences for antibodies against HSV-1 were >90% in samples from Brazil and Turkey, whereas the other four countries showed lower mean age-adjusted seroprevalences (range: 62.5-87.9%). Samples from Brazilian women showed elevated seroprevalences of antibodies against HSV-2 (40.1%), C. trachomatis (46.8%) and B. pertussis (56.6%) compared to the other five countries. Seroprevalences of anti-T. gondii antibodies (0.5%) and anti-parvovirus B19 antibodies (7.5%) were low in samples from Chinese women, compared to the other five countries. Samples from German women revealed a low age-standardised seroprevalence of anti-CMV antibodies (28.8%) compared to the other five countries. These global differences in immune status of women in childbearing age advocate country-specific prophylaxis strategies to avoid infection with ToRCH pathogens.

Abstract
BACKGROUND The aim of this study was to evaluate the possible risk factors for mortality in adult patients with candidemia by investigating the causative agents, underlying conditions and predisposing factors. MATERIAL AND METHODS The data including causative Candida species, predisposing factors, and underlying conditions of candidemia patients between the years 2015-2017 were collected and the impact of these factors on mortality was evaluated. Patients were divided into two groups as died (died patients within 30 days of the onset of candidemia) and survived and risk factors were evaluated for each group. RESULTS We found 163 adult candidemia cases during the study period. Overall 30-day mortality was 40.5%. Candida parapsilosis was the most frequent causative agent (49.1%). C. parapsilosis candidemia was more common in the survived group compared with the died group (n: 49 (61.3%) vs. n: 31 (38.8%), P=0.888). Mortality rates were significantly higher in patients with dialysis (n: 27 (69.2%) vs. n: 12 (30.8%), P<0.00) and concurrent bacteremia (n: 20 (57.1%) vs. n: 15 (42.9%), P=0.024). Survival rates were significantly higher in patients with follow-up blood cultures (n: 75 (65.8%) vs. n: 39 (34.2%), P=0.013). The most important source of candidemia was catheter (49.7%), and C. parapsilosis was the most common causative agent (58%). The catheter was removed in 96.3% of these patients and the mortality rate was 38.5%. All of the patients received antifungal therapy and there was no significant difference between the effects of antifungals on mortality (n: 65 (39.9%) vs. 98 (60.1%), P=0.607). CONCLUSIONS Dialysis and concurrent bacteremia are strong predictors of mortality in 30 days within patients with candidemia, whereas follow-up blood cultures have a protective role with lower mortality rates. In our study, the most important source of candidemia was catheter, and C. parapsilosis was the most common causative agent. The catheter was removed in almost all patients and the mortality rate was almost one third among these patients.

Abstract
BACKGROUND We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2012 to December 2017 in 523 intensive care units (ICUs) in 45 countries from Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific. METHODS During the 6-year study period, prospective data from 532,483 ICU patients hospitalized in 242 hospitals, for an aggregate of 2,197,304 patient days, were collected through the INICC Surveillance Online System (ISOS). The Centers for Disease Control and Prevention-National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI) were applied. RESULTS Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the medical-surgical ICUs, the pooled central line-associated bloodstream infection rate was higher (5.05 vs 0.8 per 1,000 central line-days); the ventilator-associated pneumonia rate was also higher (14.1 vs 0.9 per 1,000 ventilator-days,), as well as the rate of catheter-associated urinary tract infection (5.1 vs 1.7 per 1,000 catheter-days). From blood cultures samples, frequencies of resistance, such as of Pseudomonas aeruginosa to piperacillin-tazobactam (33.0% vs 18.3%), were also higher. CONCLUSIONS Despite a significant trend toward the reduction in INICC ICUs, DA-HAI rates are still much higher compared with CDC-NHSN's ICUs representing the developed world. It is INICC's main goal to provide basic and cost-effective resources, through the INICC Surveillance Online System to tackle the burden of DA-HAIs effectively.

Abstract
PURPOSE The aim of this study was to evaluate the time course of orthodontic force-induced apoptosis and receptor activator of nuclear factor-κB ligand (RANKL)-induced osteoclastogenesis in a rat model under light- and heavy-force conditions. METHODS Male Wistar rats were divided into light-force (10 cN) and heavy-force (60 cN) groups (N = 28/group). Each group was divided into four time-course subgroups to evaluate all phases of orthodontic tooth movement. Mesialization appliances were placed on three united maxillary molars unilaterally and activated. Tooth movements were calculated, and periodontal ligament (PDL) widths were measured. Expression of Bax, Bcl‑2, caspase 3, caspase 9, and RANK-RANKL were assessed by immunohistochemistry. Expression levels at the PDL-alveolar bone border were compared between experimental and control groups and force groups. RESULTS The rate of tooth movement did not differ between the force groups. PDL widths were higher on the tension side in the heavy-force group in the post-lag phase. Pro-apoptotic protein Bax expression was elevated in the heavy-force group, whereas anti-apoptotic protein Bcl‑2 expression was elevated in the light-force group. RANK expression on days 7 and 21 and RANKL expression on day 21 differed between the force groups. CONCLUSIONS Evidence of orthodontic force-induced apoptosis is more robust with stronger forces than with weaker forces. Exuberant RANKL-induced osteoclastogenesis that was seen when applying a low force results from increased RANK and RANKL expression in the post-lag phase.

AbstractIn this investigation, attempts have been made to study the corrosion inhibition properties of three new triazepine carboxylate compounds for mild steel in 1.0 M hydrochloric acid medium. The evaluation was carried out using mass loss, electrochemical impedance spectroscopy and polarization curves measurement. Impedance diagrams and Bode plots for uninhibited and inhibited systems were analyzed using Zview program. The fitted data observed trails in nearly the same pattern as the experimental results. It is showed that triazepine carboxylate compounds are very good inhibitors for mild steel corrosion in 1.0 M hydrochloric acid medium which act as mixed-type inhibitors. So, the inhibition efficiency was increased with inhibitor concentration in the order Cl–Me–CN > Me–CN > Cl–Me–CO2Et which depended on their molecular structures. Electrochemical impedance spectroscopy showed that all compounds act by the formation of a protective film at the metal surface. Surface analyses via SEM and Optical 3D profilometry were used to investigate the morphology of the steels before and after immersion in 1.0 M HCl solution containing inhibitors. The correspondence between inhibition property and molecular structure of the triazepine carboxylate compounds was investigated, using density functional theory (DFT). Experimental and DFT study was further supported by molecular dynamic simulations study.

Abstract
INTRODUCTION Myocardial infarction is one of the leading causes of morbidity and mortality worldwide. Cellular interactions of red blood cells (RBCs) and platelets with endothelial cells and cardiomyocytes play a crucial role in cardiac ischemia/reperfusion (I/R) injury. However, addressing the specific impact of such cell-to-cell interactions in commonly employed in vivo models of cardiac I/R injury is challenging due to overlap of neuronal, hormonal, and immunological pathways. This study aimed to refine a Langendorff-based ex vivo transfer model to evaluate the impact of specific blood components on cardiac I/R injury. MATERIAL AND METHODS Murine whole blood, defined murine blood components (RBCs, platelet-rich plasma [PRP], and platelet-poor plasma [PPP], respectively) as well as human RBCs were loaded to the coronary system of isolated murine hearts in a Langendorff system before initiating global ischemia for 40 minutes. Following 60 minutes of reperfusion with Krebs Henseleit Buffer, left ventricular function and coronary flow were assessed. Infarct size was determined by specific histological staining following 120 minutes of reperfusion. RESULTS Loading of murine whole blood to the coronary system of isolated murine hearts at the beginning of 40 minutes of global ischemia improved left ventricular function after 60 minutes of reperfusion and reduced the infarct size in comparison to buffer-treated controls. Similarly, isolated murine RBCs, PRP, and PPP mediated a protective effect in the cardiac I/R model. Furthermore, human RBCs showed a comparable protective capacity as murine RBCs. CONCLUSION This Langendorff-based transfer model of cardiac I/R injury is a feasible, time-, and cost-effective model to evaluate the impact of blood components on myocardial infarction. The presented method facilitates loading of blood components of genetically modified mice to murine hearts of a different mouse strain, thus complementing time- and cost-intensive chimeric models and contributing to the development of novel targeted therapies.

Abstract
With the effects of anesthetic drugs on all organs and systems, it is known it affects the central nervous system functions at different grades and durations beyond acute unconsciousness. This causes cognitive functions of upper brain activities to be affected at varying degrees after anesthesia. After exposure to anesthetic agents, psychomotor and cognitive functions are deteriorated for 10--12 h, with sensitive tests it was showed that this deterioration lasted for 1--2 days. It has also been reported that this process can last till 3 months. Rapid recovery and mental readiness of patients, applied general anesthesia, are important objects for anesthesiologists. Postoperative cognitive functions are assessed in order to investigate mental changes caused by anesthesia and surgery or determine the level of recovery by determining the effects of anesthetics. In this case report, postoperative cognitive dysfunction (POCD) after donor nephrectomy was aimed.

Abstract
Aim We aimed to assess the factors which may affect the quality of life (QoL) of the patients who underwent curative gastrectomy for gastric cancer. Subjects and Methods Patients with gastric cancer, who underwent gastrectomy with curative intent at Department of Gastrointestinal Surgery, Kartal Training and Research Hospital from January 2013 to December 2015, were retrospectively reviewed. Gastrointestinal Quality of Life Index was utilized for this research. The clinical factors that might affect QoL after gastrectomy were selected. They were demographic data (age and gender), the American Society of Anesthesiologists classification, body mass index (BMI), operative variables (level and type of resection, type of dissection [D1, D2], type of reconstruction, and additional organ resections), postoperative appetite level, type of oncological treatment, and pathological stages. One hundred and eighteen patients were included in this study. Results Eighty-seven (73.7%) of them were male and mean age was 59.4 ± 10.2 (36-74). Mean follow-up period was 25.7 ± 11.3 (6-42) months. According to multivariate analysis, advanced stage, neoadjuvant therapy, lower BMI, poor appetite, and shorter follow-up were independently associated with poorer cumulative scores. Conclusions Advanced stage, application of neoadjuvant therapy, low BMI level, and poor postoperative appetite may deteriorate the postoperative QoL of the patients with gastric cancer.

Abstract
Aim In this study, we aimed to evaluate the clinical characteristics and outcomes of the patients with anal melanoma (AM), who underwent surgical treatment. Materials and Methods This study was conducted in Kartal Training and Research Hospital between January 2010 and December 2017. All patients, who underwent surgical resection with a diagnosis of AM, were enrolled. Results A total of 10 patients were examined, 8 of them were females, and their average age was 69.2 years (range, 47-85 years). Abdominoperineal resection (APR) was performed in five (50%) patients, and local excision (LE) was performed in other five (50%) patients. Three patients (30%) had stage I disease, two (20%) had stage II disease, and five (50%) had stage III disease. All five patients in APR group had stage III disease. In the comparison of the survival period after surgery, the mean survival period of the APR group was 6.2 months (range, 1-16 months) while that of the LE group was 19.6 months (range, 7-43 months). Conclusion LE with adjuvant radiation seems to offer good locoregional control without reducing the survival and may be an option of treatment for patients with small, superficial AM. However, APR should be offered for patients with locally advanced disease or as a salvage following recurrence.

Abstract
BACKGROUND In weightlessness, alterations in organ systems have been reported. The microcirculation consists of a network of blood vessels with diameters of a few μm. It is considered the largest part of the circulatory system of the human body and essential for exchange of gas, nutrients and waste products. An investigation of the microcirculation in weightlessness seems warranted but has not yet been performed. OBJECTIVE In this paper, we outline a study in which we will investigate the possible interrelations between weightlessness and microcirculation. We will induce weightlessness in the course of parabolic flight maneuvers, which will be conducted during a parabolic flight campaign. In this study protocol also an evaluation of a possible influence of parabolic flight premedication on microcirculation will be described. METHODS The microcirculation will be investigated by sublingual intravital measurements applying sidestream darkfield microscopy. Parameters of macrocirculation such as heart rate, blood pressure and blood oxygenation will also be investigated. RESULTS In our pre-study experiments, neither dimenhydrinate nor scopolamine altered microcirculation. CONCLUSIONS As the application of motion sickness therapy did not alter microcirculation, it will be applied during the parabolic flight maneuvers of the campaign. Our results might deepen the understanding of microcirculation on space missions and on earth.

Abstract
PURPOSE The standard treatment for patients with stage III non-small cell lung cancer (NSCLC), unsuitable for resection and with good performance, is definitive radiotherapy with cisplatin-based chemotherapy. Our aim is to evaluate the effect of the maximum value of standardized uptake values (SUVmax) of the primary tumor in positron emission tomography-computed tomography (PET/CT) before treatment on complete response (CR) and overall survival. METHODS The data of 73 stage III NSCLC patients treated with concurrent definitive chemoradiotherapy (CRT) between 2008 and 2017 and had PET/CT staging in the pretreatment period were evaluated. ROC curve analysis was performed to determine the ideal cut-off value of pretreatment SUVmax to predict CR. RESULTS Median age was 58 years (range 27-83 years) and 66 patients were male (90.4%). Median follow-up time was 18 months (range 3-98 months); median survival was 23 months. 1-year overall survival (OS) rate and 5-year OS rate were 72 and 19%, respectively. Median progression-free survival (PFS) was 9 months; 1-year PFS rate and 5-year PFS rate were 38 and 19%, respectively. The ideal cut-off value of pretreatment SUVmax that predicted the complete response of CRT was 12 in the ROC analysis [AUC 0.699 (0.550-0.833)/P < 0.01] with a sensitivity of 83%, and specificity of 55%. In patients with SUVmax < 12, CR rate was 60%, while, in patients with SUV ≥ 12, it was only 19% (P = 0.002). Median OS was 26 months in patients with pretreatment SUVmax < 12, and 21 months in patients with SUVmax ≥ 12 (HR = 2.93; 95% CI 17.24-28.75; P = 0.087). CR rate of the whole patient population was 26%, and it was the only factor that showed a significant benefit on survival in both univariate and multivariate analyses. CONCLUSION Pretreatment SUVmax of the primary tumor in PET/CT may predict CR in stage III NSCLC patients who were treated with definitive CRT. Having clinical CR is the only positive predictive factor for prolonged survival.

Abstract
Serum ferroxidase I (ceruloplasmin) and ferroxidase II activities were studied in 49 uremic patients under conservative treatment, in 79 patients undergoing hemodialysis and in 56 healthy subjects, as controls. Ferroxidase I was significantly higher in both groups of patients. Ferroxidase II was significantly elevated only in patients undergoing chronic hemodialysis. The cause of this difference is not clear, but seems to be of considerable interest.

Abstract
Introduction This study aimed to evaluate the clinical efficacy of intravenous metoclopramide for the relief of pain and nausea among the emergency department patients with renal colic. Methods Patients were randomised into three groups: tenoxicam (20 mg); tenoxicam (10 mg) plus metoclopramide (10 mg); and metoclopramide (10 mg). Changes in pain and nausea were examined at the 10th, 20th and 30th minute after treatment. The development of side effects would be recorded. After the 30th minute, the need for additional pain and nausea relief was evaluated. Results Totally 80 patients were enrolled in each group. There was significant mean pain score difference as measured by visual analog scale (VAS) from 0 minute to 10th, 20th and 30th minute post-treatment for all treatment groups (p<0.001). There was no significant difference in mean VAS decrease from 0 minute to the 30th minute: tenoxicam group: 36 mm [95% confidence interval (CI) 28-43 mm] vs. tenoxicam plus metoclopramide: 45 mm (95% CI 38-52 mm) vs. metoclopramide group: 37 mm (95% CI 30-45 mm) (p=0.163). Similarly, no significant differences in mean nausea scores between the three groups were demonstrated at the 10th, 20th and 30th minute after treatment (p=0.236, 0.330 and 0.652 respectively). After the 30th minute, 43 (53%) patients needed additional pain relieving agent in the tenoxicam group compared to 27 (33%) patients in the tenoxicam-metoclopramide group and 33 (41%) patients in the metoclopramide group (p=0.030). No significant adverse drug reaction events were encountered. Conclusion Metoclopramide is as effective as tenoxicam to treat pain and nausea for patients with renal colic in the emergency department. (Hong Kong j.emerg.med.2015;22:93-99)
