The effect of interleukin-20 on periodontal tissue destruction in individuals with periodontitis.

BACKGROUND AND OBJECTIVE: Periodontitis is an inflammatory disease that destroys periodontal tissues. Interleukin-20 (IL-20), on the other hand, is known as a potent angiogenic, chemotactic, and pro-inflammatory cytokine associated with various chronic inflammatory disorders. IL-20 has a significant role in the regulation of osteoclastogenesis and osteoblastogenesis. This study aimed to evaluate the effect of IL-20 on periodontal destruction. METHODS: In this study, a total of 60 participants were included, 30 of whom were systemically and periodontally healthy (control group), and 30 were systemically healthy but had periodontitis (periodontitis group). Gingival crevicular fluid (GCF) and serum samples were collected from the participants for biochemical analysis. Enzyme-linked immunosorbent assay was used to determine the levels of IL-20, tumor necrosis factor (TNF)-α, IL1ß/IL-10, RANKL/osteoprotegerin (OPG), and matrix metalloproteinase-8 (MMP8). For statistical analysis, the independent t-test, Pearson correlation coefficients, and the Chi-square test were used. RESULTS: GCF IL-20, RANKL, RANKL/OPG, serum IL-20, RANKL, RANKL/OPG, MMP-8, TNF-α, IL-1B, and IL-1ß/IL-10 values were found to be statistically significantly higher in the periodontitis group than in the control group. GCF OPG and serum IL-10 values were found to be statistically significantly higher in the control group than in the periodontitis group. No statistically significant difference was observed between the groups in serum OPG values. A statistically significantly positive correlation was observed between serum IL-20 value and serum RANKL, RANKL/OPG, MMP-8, TNF-α, IL-1ß values, and periodontal clinical parameters. The ROC curves showed: AUC = 0.788 for GCF IL-20, and AUC = 1.000 for serum IL-20. CONCLUSION: According to the results of the study, IL-20 was found to be associated with periodontitis. The role of IL-20 in periodontal pathogenesis is related to osteoclastogenesis and collagen degradation. It is conceivable that IL-20 may increase bone destruction by both affecting the RANKL/OPG ratio and proinflammatory cytokines.

An investigation on protection properties of Tantalum (V) oxide reinforced glass screens on unexposed breast tissue for mammography examinations.

INTRODUCTION: The utilization of radiation shielding material positioned between the both breasts are crucial for the reduction of glandular dose and the safeguarding of the contralateral breast during mammographic procedures. This study proposes an alternative substance for shielding the contralateral breast from radiation exposure during mammography screening. METHODS: In this study, we present an analysis of the shielding effectiveness of transparent glass that has been doped with Tantalum (V) oxide encoded as BTZT6. The evaluation of this shielding material was conducted using the MCNPX code, specifically for the ipsilateral and contralateral breasts. The design of the left and right breast phantoms involved the creation of three-layer heterogeneous breast phantoms, consisting of varying proportions of glandular tissue (25%, 50%, and 75%). The design of BTZT6 and lead-acrylic shielding screens is implemented using the MCNPX code. The comparative analysis of dose outcomes is conducted to assess the protective efficacy of BTZT6 and lead-acrylic shielding screens. RESULTS: The utilization of BTZT6 shielding material resulted in a reduction in both breast dose and skin dose exposure when compared to the lead-acrylic shield. CONCLUSION: Based on the findings acquired, the utilization of BTZT6 shielding material screens during mammography procedures involving X-rays with energy levels ranging from 26 to 30 keV is associated with a decrease in radiation dose. IMPLICATIONS FOR PRACTICE: It can be inferred that the utilization of BTZT6 demonstrates potential efficacy in mitigating excessive radiation exposure to the breasts and facilitating the quantification of glandular doses in mammography procedures.

The effect of postoperative hepatic fibrosis factors on morbidity in mitral valve replacement surgery: A single center ten years' experience.

Background: Previous studies have shown that hepatic fibrosis indices and rates can be used to predict cardiovascular mortality and morbidity. Our aim with this study was to investigate the effect of aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio and fibrosis-4 (FIB-4) index calculated with ALT, AST, and platelet biomarkers, which are simple, fast, and relatively inexpensive and were used in previous studies to predict cardiovascular disease prognosis, on the prediction of postoperative morbidity and early mortality after mitral valve replacement (MVR) surgery. Methods: By scanning the hospital electronic health record system, 116 patients who underwent isolated MVR or MVR + tricuspid valve intervention were identified from 178 patients who underwent MVR with the standard sternotomy procedure between 2011 and 2021. The study was completed with 81 of these patients. Patients were divided into AST/ALT <2 (Group 1) and >2 (Group 2). In addition, the same patients were divided into FIB-4 index <3.25 (Group 3) and >3.25 (Group 4), and a total of four groups were formed. Results: The mean age of Group 2 was significantly higher than Group 1 (P = 0.049). In addition, the mean age of Group 4 was significantly higher than Group 3 (P = 0.003). Postoperative complications did not differ between Groups 1 and 2 (P > 0.05). While noninvasive mechanincal ventilation (NIMV) requirements did not differ between Groups 3 and 4 (P > 0.05), MV duration and intensive care unit stay were significantly longer in Group 4 (P < 0.05). Conclusion: The AST/ALT ratio, which has been shown to be a predictor of cardiovascular mortality in various studies, was not useful in predicting mortality and morbidity in our study. However, a high FIB-4 index, another hepatic fibrosis index, was found to be associated with increased perioperative bleeding, duration of mechanical ventilation, and cardiac intensive care unit stay, which are important criteria in the prediction of morbidity in cardiovascular surgery.

Dexmedetomidine alleviates vacuolization and necrosis in tubular epithelial cells induced by aortic cross-clamping.

OBJECTIVE: Acute kidney injury (AKI) is one of the main causes of mortality in patients undergoing emergency surgery due to an abdominal aortic aneurysm. This study aimed to determine the potential nephroprotective characteristics of dexmedetomidine (DMD) for the establishment of a standard therapeutic method for AKI. MATERIALS AND METHODS: Thirty Spraque Dawley rats were allocated to 4 groups: control, sham, ischemia-reperfusion, and ischemia/reperfusion (I/R)+dexmedatomidine. RESULTS: Necrotic tubules, degenerative Bowman's capsule and vascular congestion were observed in the I/R group. In addition, there was an increase in tissue malondialdehyde (MDA), interleukin (IL)-1 and IL-6 levels in tubular epithelial cells. In contrast, we observed decreased tubular necrosis, IL-1, IL-6 and MDA levels in the DMD treatment group. CONCLUSIONS: DMD has a nephroprotective effect against acute kidney injury resulting from I/R, which is related to aortic occlusion used in the treatment of ruptured abdominal aortic aneurysms.

Radioprotective effects of dexmedetomidine on X-ray-induced testicular damage.

OBJECTIVE: Approximately 70% of cancer patients require radiotherapy. However, despite its effectiveness in the treatment of cancer, radiotherapy can also affect and damage surrounding healthy tissues in addition to tumorous tissues. Since testicular tissues are highly radiosensitive, radiotherapy can cause impairments in spermatogenesis leading to infertility. The purpose of this study was to examine the potential radio-protective effect of dexmedetomidine (Dex), an α2-adrenoceptor agonist, on oxidative stress and apoptosis in testicular tissues caused by x-irradiation in rats. MATERIALS AND METHODS: Thirty male Sprague-Dawley rats were allocated into three groups of ten (n=10): control, irradiation (IR), and IR + Dex groups. The IR group was exposed to a single dose of 2 Gy IR. The IR+Dex group was given a single intraperitoneal (i.p.) dose of 100 µg/kg Dex before IR. The control group received a single dose of saline solution i.p. Testicular tissues removed 24 hours after IR were subjected to histochemical, biochemical, and immunohistochemical analysis. RESULTS: IR resulted in increased malondialdehyde (MDA) activity and significant changes in testis tissues. However, the application of Dex elevated glutathione levels by preventing MDA formation. In addition, Dex decreased tubular epithelial apoptosis via elevated Cleaved Caspase-3 expressions. CONCLUSIONS: Dex exhibited a radio-protective effect against lipid peroxidation and apoptosis caused by IR.

Ultrasensitive detection of circulating LINE-1 ORF1p as a specific multi-cancer biomarker.

Improved biomarkers are needed for early cancer detection, risk stratification, treatment selection, and monitoring treatment response. While proteins can be useful blood-based biomarkers, many have limited sensitivity or specificity for these applications. Long INterspersed Element-1 (LINE-1, L1) open reading frame 1 protein (ORF1p) is a transposable element protein overexpressed in carcinomas and high-risk precursors during carcinogenesis with negligible detectable expression in corresponding normal tissues, suggesting ORF1p could be a highly specific cancer biomarker. To explore the potential of ORF1p as a blood-based biomarker, we engineered ultrasensitive digital immunoassays that detect mid-attomolar (10-17 M) ORF1p concentrations in patient plasma samples across multiple cancers with high specificity. Plasma ORF1p shows promise for early detection of ovarian cancer, improves diagnostic performance in a multi-analyte panel, and provides early therapeutic response monitoring in gastric and esophageal cancers. Together, these observations nominate ORF1p as a multi-cancer biomarker with potential utility for disease detection and monitoring.

Therapeutic and Nutraceutical Effects of Polyphenolics from Natural Sources.

The prevalence of cardiovascular disease, oxidative stress-related complications, and chronic age-related illnesses is gradually increasing worldwide. Several causes include the ineffectiveness of medicinal treatment therapies, their toxicity, their inability to provide radical solutions in some diseases, and the necessity of multiple drug therapy in certain chronic diseases. It is therefore necessary for alternative treatment methods to be sought. In this review, polyphenols were identified and classified according to their chemical structure, and the sources of these polyphenol molecules are indicated. The cardioprotective, ROS scavenging, anti-aging, anticancer properties of polyphenolic compounds have been demonstrated by the results of many studies, and these natural antioxidant molecules are potential alternative therapeutic agents.

Comparison of C-MAC vs. McGrath video laryngoscopes on glottic exposure and endotracheal intubation success with stylet usage in obese patients.

OBJECTIVE: Cases of obesity are rising in parallel with the number of obese patients scheduled for anesthesia in which difficult airway is encountered. Video laryngoscopes (VL) have emerged as a popular device for the management of patients with difficult airway. The present study compares the success rate of intubation in obese patients using stylet in the ramped position using either a McGrath or C-MAC VLs. PATIENTS AND METHODS: Class II/III obese patients who were intubated with either McGrath (Group M, n=50) or C-MAC (Group C, n=50) laryngoscopes were assessed for the presence of difficult airway using the Difficult Airway Assessment tool, the Airway Difficulty Score and the Total Airway Score. The intubation attempts were made after the best glottic view, direct and indirect Cormack-Lehane (CL) score, and intubation time were recorded. In the event of failure, a further intubation attempt was made using a styled, and the intubation time was again recorded. If the intubation failed again, a third attempt was made using a C-MAC D-Blade. The Intubation Difficulty Scale score was recorded after the intubation. RESULTS: There was no statistically significant difference between groups in terms of demographic data, the number of patients with decreased CL score, the number of attempts required for intubation, or the first and second intubation time. The ADS Score, TAS Score, CL Score DL, and CL Score IN were found to be important risk factors for a second intubation requirement, and the cut-off value was found to be 8.50 for the ADS Score and 4.50 for the TAS Score in these patients. In the 38 patients who required a second intubation attempt, the procedure was successful in all, but one patient required a third attempt of intubation with C-MAC D-blade. CONCLUSIONS: Both McGrath and C-MAC were effective and comparable for best glottic view with no failed intubation. It was concluded that regardless of the type of video laryngoscope used, the use of a stylet in the first intubation attempt increases the success of intubation.

Assessment of quality of life, anxiety, depression, and sleep quality in women with fibromyalgia and their spouses.

OBJECTIVE: Fibromyalgia syndrome (FMS) is a chronic disease that is more common in adult women and is characterized by widespread pain in the body, especially in the musculoskeletal system. Fatigue, sleep disturbance, anxiety disorder, and depression can be observed in this syndrome alongside pain. The aim of our study was to investigate the effect of FMS on the quality of life, psychological condition, and sleep quality of affected female patients and their spouses compared to women without FMS and their spouses. PATIENTS AND METHODS: Thirty female patients diagnosed with fibromyalgia and their spouses and 38 healthy women and their spouses similar in age to these patients voluntarily participated in our study (136 participants total). The diagnosis of the patients was made according to the American College of Rheumatology. Turkish versions of the Short Form-36 (SF-36), the Hospital Anxiety and Depression Scale, and the Pittsburgh Sleep Quality Index (PSQI) questionnaires with validity and reliability were applied to all participants. The statistical analyses were carried out using SPSS 24.0 for Windows (SPSS Inc., Chicago, IL, US). Differences with p-values of ≤0.05 were statistically significant, and all results are expressed with a 95% confidence interval. RESULTS: A total of 136 people, including women with FMS (n=30), spouses of FMS women (n=30), non-FMS control women (n=38), and spouses of the control women (n=38), were included in the study. The patient and control groups were similar in age and gender. However, participants in the study group had higher mean Body Mass Indexes compared to the controls. Quality of life and its sub-scales (except SF-36/Social function parameter), depression, anxiety status, and sleep quality were significantly different between the patients and controls. Additionally, quality of life and its sub-scales (except SF-36/Social function parameter), depression, and anxiety status were significantly different between the spouses of the patients and controls. There were no significant differences between the groups regarding the mean SF-36/SF (p=0.995 for both). Additionally, there was no significant difference between the spouse of the patient and control regarding the mean PSQI values (p=0126). CONCLUSIONS: We believe that new and more comprehensive studies are necessary regarding the spouses of women with FMS in depression, anxiety, sleep quality disorders that we frequently see in women with FMS, and other psychosocial conditions that we have not mentioned here. In conclusion, women with FMS and their spouses.

Diagnosis and treatment of cardiac amyloidosis: position statement of the German Cardiac Society (DGK).

Systemic forms of amyloidosis affecting the heart are mostly light-chain (AL) and transthyretin (ATTR) amyloidoses. The latter is caused by deposition of misfolded transthyretin, either in wild-type (ATTRwt) or mutant (ATTRv) conformation. For diagnostics, specific serum biomarkers and modern non-invasive imaging techniques, such as cardiovascular magnetic resonance imaging (CMR) and scintigraphic methods, are available today. These imaging techniques do not only complement conventional echocardiography, but also allow for accurate assessment of the extent of cardiac involvement, in addition to diagnosing cardiac amyloidosis. Endomyocardial biopsy still plays a major role in the histopathological diagnosis and subtyping of cardiac amyloidosis. The main objective of the diagnostic algorithm outlined in this position statement is to detect cardiac amyloidosis as reliably and early as possible, to accurately determine its extent, and to reliably identify the underlying subtype of amyloidosis, thereby enabling subsequent targeted treatment.

Resveratrol prevents acute renal injury in a model of ruptured abdominal aortic aneurysm.

OBJECTIVE: To examine the biochemical and histopathological effects of ischemia/reperfusion (I/R) injury in a ruptured abdominal aortic aneurysm (RAAA) model in rats, and to investigate the potential protective role of resveratrol. METHODS: Thirty-two male Sprague-Dawley rats were randomly assigned into four groups-control, I/R, sham (I/R + solvent/dimethyl sulfoxide), and I/R + resveratrol. The control group underwent midline laparotomy only. In the other groups, infrarenal vascular clamps were attached following 60-min shock to the abdominal aorta. Ischemia was applied for 60 min followed by reperfusion for 120 min. In the I/R + resveratrol group, intraperitoneal 10 mg/kg resveratrol was administered 15 min prior to ischemia and immediately before reperfusion. The I/R + dimethyl sulfoxide group received dimethyl sulfoxide, and the I/R group was given saline solution. All animals were sacrificed by exsanguination from the carotid artery at the end of the experiment. In addition to histopathological examination of the rat kidney tissues, malondialdehyde, glutathione, catalase, and nitric oxide levels were also investigated. RESULTS: A decrease in glutathione, catalase and nitric oxide levels, together with increases in malondialdehyde levels, numbers of apoptotic renal tubular cells, caspase-3 levels, and tubular necrosis scores, were observed in the IR and I/R + dimethyl sulfoxide groups. In contrast, resveratrol increased glutathione, catalase and nitric oxide levels in renal tissues exposed to I/R, while reducing malondialdehyde levels, apoptotic renal tubular cell numbers, caspase-3 levels, and tubular necrosis scores. CONCLUSION: Our findings suggest that resveratrol can be effective against I/R-related acute kidney damage developing during RAAA surgery by reducing oxidative stress and apoptosis.

Mediastinal Thymolipoma: An Evaluation of the Clinical and Radiological Features and the Surgical Outcomes in 11 Cases

ABSTRACT Background: Thymolipoma is a rare benign tumour of the mediastinum, accounting for 2%-9% of all thymic tumours. Although many case reports have been published in the literature, few studies have analysed the clinical and radiological features and the surgical outcomes of this tumour. Objective: To evaluate the clinical and radiological features and the surgical outcomes of the patients with thymolipoma. Methods: We reviewed the records of the Pathology Department from the beginning of 2005 to the end of 2013. Results: We identified 11 patients with thymolipoma. There were eight male and three female patients. Their ages ranged from 27 to 72 years, with the mean age of 40 years. All patients described pulmonary or extrapulmonary symptoms. Two patients (18.2%) had myasthenia gravis. Chest X-ray was normal in four patients. Computed tomography of the thorax revealed a mass located in the anterior mediastinum in all patients. It showed fat attenuation in 4 of 11 patients (36.4%). Thymectomy was performed in all patients. The surgical approach was thoracotomy in five, sternotomy in four and video-assisted thoracic surgery in two patients. Thymolipomas ranged in size from 4 to 33 cm. One patient died 2 years after surgery. None of the remaining patients had evidence of recurrence on follow-up. Conclusion: Thymolipoma is a rare tumour of the thymus. It may be associated with myasthenia gravis. Surgical resection is the treatment of choice in the patients with thymolipoma. Complete surgical resection is the cure in most patients.

COSMIC RADIATION EXPOSURE CALCULATIONS FOR INTERNATIONAL AND DOMESTIC FLIGHTS DEPARTS FROM ISTANBUL AND ANKARA.

In this study, cosmic radiation doses were calculated for domestic and international flights departing from Istanbul and furthermore for domestic flights departing from Ankara using a software program called CARI-7A and also a mathematical method approach. Main parameters for calculating cosmic radiation are vertical cut-off rigidity, flight duration, latitude-longitude and altitude of the flight. Our calculation results agree with the measurements for domestic and international flights departing from Istanbul and Ankara.

A possible connection between circulating 25-hydroxy-vitamin D and molecular response in chronic myeloid leukemia.

OBJECTIVE: In this study we aimed to evaluate whether there is a link between circulating 25-OH-D levels and molecular response in chronic myeloid leukemia (CML). MATERIAL AND METHOD: A total of 61 patients with CML (31 women, 30 men) were recruited in this cross-sectional study. RESULTS: Binary logistic regression analysis demonstrated that increased vitamin D levels were independently associated with molecular response in subjects with CML. CONCLUSION: Our results indicated for the first time in the literature that severe deficiency of vitamin D was independently associated with molecular unresponsiveness in subjects with CML. 25-OH-D may be contributing to molecular response in the patients (Tab. 3, Ref. 24).

Molecular characterisation and phylogenetic analysis of Marek's disease virus in Turkish layer chickens.

1. There is no current data about the genotypes of Marek's disease virus (MDV) in Turkish poultry flocks; hence, this study was performed to analyse CVI988/Rispens, turkey herpesvirus (HVT) vaccine viruses and MDV field viruses as well as to perform phylogenetic analysis of MDV in Turkish layer chickens. 2. In 2017 and 2018, a total of 602 spleen samples from 49 layer flocks were collected from the Marmara, West Black Sea and Aegean regions. DNA was extracted from the spleen samples and the samples were analysed by real-time PCR probe assay to detect CVI988/Rispens and HVT vaccine viruses and MDV field strains. Samples found positive for MDV by real-time PCR were subjected to PCR using the Meq gene primers for phylogenetic analysis. 3. Amongst 49 flocks, virulent MDV was detected in nine flocks. CVI988/Rispens and HVT vaccine strains were detected in 47 flocks and HVT in all 49 flocks. Splenomegaly, hepatomegaly and tumours in the oviduct were observed in chickens of affected flocks. Virulent MDV was detected in 120 out of 602 spleen samples. Sequencing and phylogenetic analyses showed that MDVs detected in this study were closely related to MDV strains from Italy, Poland, Saudi Arabia, Iraq, India and China but showed diversity with MDV strains from Egypt and Hungary. Multiple sequence analysis of the Meq protein revealed several point mutations in deduced amino acid sequences. Interestingly, CVI988/Rispens vaccine virus from China (AF493555) showed mutations at position 66 (G66R) and 71 (S66A) along with two other vaccine strains from China (GU354326.1) and Russia (EU032468.1), in comparison with the other vaccine strain CVI988/Rispens (DQ534538). The molecular analyses of the Meq gene suggested that Turkish field strains of MDV are in the class of virulent or very virulent pathotypes. 4. The results have shown that MDV still affects poultry health, and the phylogenetic and amino acid variation data obtained will help in vaccination and control strategies.

[Diagnostics and Treatment of Cardiac Sarcoidosis - Consensus Paper of the German Respiratory Society (DGP) and the German Cardiac Society (DGK)]. / Diagnostik und Therapie der kardialen Sarkoidose.

Sarcoidosis is a multisystemic granulomatous disorder which affects the respiratory system in the majority of the cases. Symptomatic cardiac manifestations are found in less than 10 % of the affected cohorts and show a large heterogeneity based on the ethnic background. Cardiac sarcoidosis is not only found in patients with rhythmogenic heart disease, such as atrial and ventricular fibrillation but also in all phenotypes of cardiomyopathy. The overall morbidity and mortality caused by cardiac sarcoidosis in Germany remains unclear and large prospective international observational studies.underline the importance of this disease entity. This consensus paper on diagnostic and therapeutic algorithms for cardiac sarcoidosis is based on a current literature search and forms an expert opinion statement under the auspices of the German Respiratory Society and the German Cardiac Society. The rationale of this statement is to provide algorithms to facilitate clinical decision-making based on the individual case situation.

Effects of infliximab against carbon tetrachloride-induced intestinal injury via lipid peroxidation and apoptosis.

Carbon tetrachloride (CCL4) is often employed in the production of chlorofluorocarbons, petroleum refining, oil and rubber processing, and laboratory applications. Oral, subcutaneous, and inhalation exposure to CCL4 in animal studies have been shown to be capable of leading to various types of cancer (benign and malignant, liver, breast, and adrenal gland tumors). The present study also evaluated the protective role of infliximab (INF) against the deleterious effects of CCL4 on the intestinal system. Twenty-four male Sprague-Dawley rats were randomly assigned into three groups, control (n = 8), CCL4 (n = 8), and CCL4 + INF (n = 8). The control group received 1 mL isotonic saline solution only via intraperitoneal (i.p.) injection. The CCL4 group received a single i.p. dose of 2 mL/kg CCL4. The CCL4 + INF group received a single i.p. dose of 7 mg/kg INF followed 24 h later by a single dose of 2 mL/kg CCL4. All rats were euthanized 2 days following drug administration. CCL4 group samples also exhibited diffuse loss of enterocytes, vascular congestion, neutrophil infiltration, an extension of the subepithelial space and significant epithelial lifting along the length of the villi with a few denuded villous tips. In addition, CCL4 treatment increased intestinal malondialdehyde (MDA) level and caspase-3 positivity. On the other hand, INF decreased MDA levels, caspase-3 positivity, and loss of villous. Our findings suggest that CCL4 appears to exert a highly deleterious effect on the intestinal mucosa. On the other hand, INF is effective in preventing this CCL4-induced intestinal injury by reducing oxidative stress and apoptosis.

Characteristics of Turkish children with Type 2 diabetes at onset: a multicentre, cross-sectional study.

AIMS: To describe the baseline clinical and laboratory findings and treatment modalities of 367 children and adolescents diagnosed with Type 2 diabetes in various paediatric endocrinology centres in Turkey. METHODS: A standard questionnaire regarding clinical and laboratory characteristics at onset was uploaded to an online national database system. Data for 367 children (aged 6-18 years) newly diagnosed with Type 2 diabetes at 37 different paediatric endocrinology centres were analysed. RESULTS: After exclusion of the children with a BMI Z-score < 1 SD, those with genetic syndromes associated with Type 2 diabetes, and those whose C-peptide and/or insulin levels were not available, 227 cases were included in the study. Mean age was 13.8 ± 2.2 (range 6.5-17.8) years, with female preponderance (68%). Family history of Type 2 diabetes was positive in 86% of the children. The mean BMI was 31.3 ± 6.5 kg/m2 (range 18.7-61) and BMI Z-score was 2.4 ± 0.8 (range 1-5). More than half (57%) of the children were identified by an opportunistic diabetes screening due to existing risk markers without typical symptoms of diabetes. Only 13% (n = 29) were treated solely by lifestyle modification, while 40.5% (n = 92) were treated with metformin, 13% (n = 30) were treated with insulin, and 33.5% (n = 76) were treated with a combination of insulin and metformin initially. Mean HbA1C levels of the insulin and combination of insulin and metformin groups were 98 (11.1%) and 102 mmol/mol (11.5%), respectively, and also were significantly higher than the lifestyle modification only and metformin groups mean HbA1C levels (70(8.6%) and 67 mmol/mol (8.3%), respectively). CONCLUSIONS: An opportunistic screening of children who are at high risk of Type 2 diabetes is essential, as our data showed that > 50% of the children were asymptomatic at diagnosis. The other important result of our study was the high rate of exclusion from the initial registration (38%), suggesting that accurate diagnosis of Type 2 diabetes in youth is still problematic, even for paediatric endocrinologists.

Phylogeny and evolution of infectious bursal disease virus circulating in Turkish broiler flocks.

The emergence of new infectious bursal disease virus (IBDV) variants can threaten poultry health and production all over the world causing significant economic losses. Therefore, this study was performed to determine IBDV molecular epidemilogy, VP2 gene variation, and corresponding pathological lesions in IBDV infected chickens in Turkey. For this, 1855 bursa of Fabricius samples were collected from 371 vaccinated broiler flocks. Atrophia and haemorrhages were seen in the bursa Fabricius of very virulent IBDV (vvIBDV) infected chickens. Partial VP2 gene was sequenced and phylogenetic, recombination, and evolutionary analyses were performed. 1548 (83.5%) out of 1855 of bursa of Fabricius samples were IBDV positive and 1525 of those could be sequenced. The recombination analysis did not detect occurrence of any recombination event among the Turkish strains. Among 1525 sequenced samples, 1380 of them were found to be classical strains. Among 1380 classical strains, 1317 were similar to IBDV 2512, 11 to Faragher 52/70, 40 to 228 E, and 12 to Lukert strain. Out of 1525 reverse transcriptase ploymerase chain reaction positive samples, 144 of them were found to be similar to vvIBDV-VP2 gene reported to GenBank previously. The phylogenetic tree performed on a broad sequence dataset demonstrated grouping of vvIBDV Turkish strains in three different clusters, including sequences collected also from Iraq and Kuwait (Cluster 1), Indian (Cluster 2), and a distinct Turkish-only cluster (Cluster 3). The evolutionary rate estimation on branches/clades including Turkish strain mirrored the expected one for RNA viruses and no significant differences were found among different considered branches. In conclusion, results of this study indicate that vvIBDV strains similar to those circulating in various countries in the Middle East are present and undergoing evolution in chickens from Turkish broiler flocks. This point needs to be taken into account in planning adequate control strategies.

Gastroprotective effect of apricot kernel oil in ethanol-induced gastric mucosal injury in rats.

We investigated the gastroprotective effect of apricot kernel oil on ethanol induced gastric ulcer in rats. Male Wistar albino rats were divided into control, ethanol and apricot kernel oil + ethanol groups. The fatty acid composition of apricot kernel oil was determined using GC-MS. A gastric ulcer index was defined as the area percentage of the gastric mucosa consisting of ulcerated tissue. Gastric tissue was investigated by TUNEL staining for apoptosis, immunohistochemical iNOS staining, measurement of gastric IL-10 and IL-6 expression by ELISA and assays of catalase, malondialdehyde and superoxide dismutase. The ethanol group exhibited a higher gastric ulcer score, increased IL-6 level, increased number of inducible nitric oxide synthase-positive and TUNEL positive cells, and a higher MDA level compared to the control group. The apricot kernel oil + ethanol group exhibited significantly fewer gastric lesions compared to the ethanol group. Apricot kernel oil protects rat gastric mucosa against ethanol induced injury by its anti-inflammatory, anti-oxidative and anti-apoptotic effects, and might be useful for reducing the severity of gastric ulcers.
