Abstract
Kernels of cotton provide lint and linter for textiles, oil and protein for food and feed. Cotton seed is formed following fertilization between an ovule and a pollen grain. The seed coat is maternal in origin, whereas the embryo and attached cotyledonary leaves are hybrids of parental lines. The extraction of genomic DNA from an ungerminated whole, a portion or mixed seeds are prerequisite in genetic and genomic studies of cotton. As far as our knowledge, there is only one method of nondescriptive DNA extraction from ungerminated cotton seeds without affecting the seed germination capability, but it has technical difficulties and requires special equipment. Furthermore, the amount of DNA extracted using the published method is low and, therefore, it is only suitable for routine marker assisted selection studies. In this study, a DNA extraction protocol referred to as the CTAB-LiCl was developed for single whole cotton seed, a portion of cotton seed and bulked cotton seeds. This protocol uses a combination of CTAB and LiCl to lyse cells and deplete RNAs simultaneously. The CTAB-LiCl DNA extraction method was evaluated in ninety-six individuals of six different cotton cultivars along with two genetic standards of cotton, TM-1 (G. hirsutum L.), Pima 3-79 (G. barbadense L.), and several other plant species of different plant genera. Results revealed that this method produced high quality and amounts of DNA as confirmed by spectrophotometry, agarose gel, restriction enzyme digestion, polymerase chain reaction, and library production for next generation sequencing studies of whole genome bisulfite sequencing. It does not require the use of liquid nitrogen, RNase, proteinase K, or beta-mercaptoethanol and can be completed in approximately 2 h. Small tissues of the chalaza ends of ungerminated cotton seeds could be used to obtain high quality and quantity of DNA ranging from 14 to 28 µg without affecting the seeds' germination ability, allowing marker-assisted selection before planting and flowering.

Abstract
BACKGROUND In ovo application is the process of administering some nutrients or components into the egg. The main purpose of this application is to ensure that some nutrients are provided to chicks with a short incubation period. Few studies were conducted with taurine in fertile eggs; especially, no observation of hatchability and chick quality has been found. In addition, taurine has an anti-stress impact that fights oxidative factors. OBJECTIVE To assess the hatchability and chick quality after in ovo taurine administration. To determine the stress that may occur as a result of in ovo application and whether taurine has a stress-reducing effect. METHODS A total of 1200 fertile eggs from a 34-week-old broiler breeder (Ross 308) flock were categorized into 4 groups with 75 eggs per replicate: control (uninjected), taurine group (0.30 mL dissolved taurine in distilled water), sham control (sterile distilled water) and perforation (eggs perforated and then waxed). On day 14 of incubation, an in ovo injection was administered to the albumen. Data on hatching parameters and hepatic HSP70 levels were obtained using relevant formulas and western blotting, respectively. RESULTS Control chicks exhibited higher hatchability than other groups, with the taurine group showing the lowest hatchability. The HSP70 levels were the highest in the perforation group compared to the control group. An increase of 21.37% in the taurine group and 83.45% in the sham control group was observed compared to the control group. CONCLUSIONS The findings suggest that in ovo application may induce increased stress, whereas taurine may have positive effects in mitigating the stress caused by in ovo application.

Abstract
Feline Infectious Peritonitis (FIP) is a fatal disease caused by feline coronaviruses. The causative agent is Feline Infectious Peritonitis Virus, a mutation of Feline Enteric Coronavirus. Feline Corona Virus is very common in the cat population. In Feline Corona Virus infected cats, the development of FIP depends on the cat's immune response. FIP disease is more common in young and old cats because young and old animals have a weaker immune system. The acute phase response is a complex systemic reaction that occurs as a response to acute or chronic inflammatory processes such as infection, neoplasia or immunological disorders, tissue damage, trauma and surgery. The study material included 15 cat with presumptive FIP (study group) and 10 healthy cats (control group). Of the 15 cats, 9 (60%) showed dry and 6 (40%) effusive form. Serum amyloid A (SAA), haptoglobin (Hp), α1-acid glycoprotein (AGP), albumin, interleukin-6 (IL-6), hepcidin, alanine-amino transferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), blood urea nitrogen(BUN), and creatinine levels were measured in the serum collected from both groups. There were no difference between the wet and dry FIP in albumin values; haptoglobin, α1-acid glycoprotein, SAA and hepcidin values were significantly different between the two groups. IL-6, showed significant difference in both wet and dry FIP groups. It was also concluded that hepcidin may be used as a biomarker in Feline Infectious Peritonitis disease like other acute phase proteins.

Abstract
OBJECTIVE Cancer is the second most common non-communicable disease group in the world and its frequency is increasing. In parallel, side effects of drugs used in cancer treatment are frequently encountered. Doxorubicin (DOX) is one of the most effective multi-purpose anticancer drugs. However, its use is significantly limited due to the risk of cardiotoxicity. Sodium-glucose cotransporter-2 inhibitors are a group of antidiabetic drugs that have been shown to reduce cardiovascular events. Our aim is to examine the preventive effect of dapagliflozin on DOX-induced cardiac damage. SUBJECTS AND METHODS We used 30 albino rats. 20 of 30 rats were administered doxorubicin for cardiomyopathy model. The rats in the DOX arm were divided into two groups: those given penicillin and placebo. After the rats were terminated, tissues were prepared for histopathological and immunohistochemical examination. TNF-α, pro-BNP, troponin T and plasma FGF-21 levels were also measured in plasma. RESULTS The mean concentrations of cTnT and pro-BNP in the plasma of the DOX treated rats demonstrated a significantly higher value compared to the control group. Treatment with dapagliflozin caused a significant reduction in plasma cTnT, pro-BNP and TNF-α levels concentrations compared to the DOX control group (p < 0.001). The group of rats treated with dapagliflozin was effective in significantly decreasing the FGF-21 concentration and the percentage of fibronectin immunoexpression compared to the DOX control group (p < 0.0001). CONCLUSIONS This study revealed, for the first time, that dapagliflozin can improve DOX-induced cardiac dysfunction and pathological changes in non-diabetic rats. This result has shown that dapaglifozin, may be promising in terms of preventing cardiac damage that may develop in cancer treatment.

Abstract
BACKGROUND The role of Ca-125 in endometrial cancer is not fully known. Some authors have reported high Ca-125 levels in patients with recurrent or advanced endometrial cancer, whereas others have stated that Ca-125 levels and the advance of the disease were not correlated in endometrial cancer. This makes it inevitable for clinicians to search for different measurement methods or interpretation of the present tumor markers. The aim of this study was to evaluate the relationship between Ca-125 values of the serum and abdominal lavage fluid and postoperative histopathological parameters in patients with endometrial carcinoma. METHODS The study included patients who were diagnosed with endometrial cancer in the Gynecology Clinic and were planned to undergo surgery. The correlations of clinicopathological parameters with preoperative values of Ca-125 measured from serum and abdominal lavage fluid were investigated. The Spearman correlation test was applied in the analysis of correlations of serum and abdominal lavage fluid Ca-125 values with postoperative tumor characteristics. RESULTS The serum Ca-125 values were determined to be positively correlated with surgical stage, tumor diameter, and lymph node involvement (p = 0.03; p = 0.04; and p = 0.01, respectively). No correlation was determined between tumor grade and serum Ca-125 level. The level of Ca-125 in the abdominal lavage fluid was observed to be correlated with surgical stage and tumor grade, but not with tumor diameter or lymph node involvement (p = 0.01, p = 0.04, respectively). CONCLUSIONS The value of Ca-125 in the abdominal lavage fluid has a positive correlation with the surgical stage and tumor grade in patients with endometrial carcinoma.

Abstract
The nuclear ribosomal DNA (nrDNA) sequences are often used for phylogenetic analysis among organisms. Because DNA cytosine methylation and nucleolar dominancy are two common epigenetic mechanisms of nrDNA, we hypothesized that internal transcribed spacer 1 (ITS1), 5.8S rRNA and ITS2 of nrDNA sequences could be used as epigenetic biomarkers. Thus, this research was undertaken to study level and pattern of site-specific cytosine methylation of ITS1, 5.8S and ITS2 in nine tissues and/or developmental stage of pepper Capsicum annuum L. cultivar Demre Sivrisi. Tissues studied consisted of young and old roots at 30 and 90 days after sowing (das), mature dry seeds and seeds at 26 days of post anthesis (dpa), flowering buds at 1 day before flowering, pericarps at 3, 15 and 65 dpa. Levels and patterns of DNA cytosine methylation were identified at single base resolution using bisulfite conversion sequencing. Results of this study revealed that DNA cytosine level and pattern of ITS1, 5.8S and ITS2 were different in most tissues and/or developmental stages studied. In addition, methylation levels of CG, CHG and CHH contexts were also significantly different among the regions. Based on the findings of this study, it was concluded that high level of methylation of nrDNA sequences was relatively higher as observed in transposable element and promoter. On the other hand, its tissue-specific gene expression was effective as that of gene body and promoter methylation. Overall findings revealed that methylation levels of nrDNA could be used as biomarkers for tissue identification or age estimation in plants.

Abstract
Introduction: In this study, we aimed to determine if neutrophil to lymphocyte ratio could predict long term morbidity and mortality in patients who hospitalized for non-ST segment elevation acute coronary syndrome (NSTE-ACS) and had coronary slow flow on coronary angiography. Methods: In this observational study, 111 patients who presented with NSTE-ACS and diagnosed with coronary slow flow phenomenon on angiographic examination were included. Neutrophil to lymphocyte ratio (NLR) calculated as the ratio of the number of neutrophils to the number of lymphocytes. Patients classified into three groups according to NLR values. The term coronary slow flow phenomenon was depicted by calculating Thrombolysis in Myocardial Infarction frame count.Patients were followed up and the occurrence of recurrent angina, recurrent myocardial infarction, and long-term mortality was determined using medical records, phone calls, or face-to-face interviews. P values <0.05 considered to indicate statistical significance. Results: Recurrent angina and myocardial infarction occurred more frequently in the highest NLR tertile compared with middle and lowest NLR tertiles. High NLR group (NLR≥ 3.88 n=38) was significantly associated with younger age and smoking status. WBC, troponin I and CRP levels increased as the NLR tertile increased. Recurrent myocardial infarction and angina showed strong relationship with increasing NLR values. In multivariate regression analyses smoking and high NLR levels were independent predictors of recurrent myocardial infarction (HR:4.64 95%CI 0.95-22.52 P=0.04, HR: 1.48 95%CI 1.16-1.90 P<0.01 respectively) in the long term follow up. Conclusion: Our study demonstrated that high NLR values can be a valuable prognostic tool in the long term follow up of patients who presented with NSTE-ACS and diagnosed with slow flow phenomenon on coronary angiography.

Abstract
Purpose Respiratory diseases have a highly multifactorial etiology where different mechanisms
contribute to the individual's susceptibility. We conducted a deep characterization of loci
associated with asthma and lung function by previous genome-wide association studies
(GWAS). Methods Sixteen variants were selected from previous GWAS of childhood/adult asthma and pulmonary
function tests. We conducted a phenome-wide association study of these loci in 4,083 traits
assessed in the UK Biobank (n = 361,194 participants). Data from the Genotype-Tissue
Expression (GTEx) project were used to conduct a transcriptomic analysis with respect to
tissues relevant for asthma pathogenesis. A pediatric cohort assessed with the International
Study of Asthma and Allergies in Children (ISAAC) Phase II tools was used to further explore
the association of these variants with 116 traits related to asthma comorbidities. Results Our phenome-wide association studies (PheWAS) identified 206 phenotypic associations with
respect to the 16 variants identified. In addition to the replication of the phenotypes tested
in the discovery GWAS, we observed novel associations related to blood levels of immune cells
(eosinophils, neutrophils, monocytes, and lymphocytes) for the asthma-related variants.
Conversely, the lung-function variants were associated with phenotypes related to body fat
mass. In the ISAAC-assessed cohort, we observed that risk alleles associated with increased
fat mass can exacerbate allergic reactions in individuals affected by allergic respiratory
diseases. The GTEx-based analysis showed that the variants tested affect the transcriptomic
regulation of multiple surrounding genes across several tissues. Conclusions This study generated novel data regarding the genetics of respiratory diseases and their
comorbidities, providing a deep characterization of loci associated with asthma and lung
function.

Abstract
Mucopolysaccharidosis type VI (MPS VI) is a lysosomal storage disorder (LSD) characterized by a chronic, progressive course with multiorgan involvement. In our study, clinical, biochemical, molecular findings, and response to enzyme replacement therapy (ERT) for at least 6 months were evaluated in 20 patients with MPS VI. Treatment effects on clinical findings such as liver and spleen sizes, cardiac and respiratory parameters, visual and auditory changes, joints' range of motions, endurance tests and changes in urinary glycosaminoglycan excretions, before and after ERT were analyzed. ERT caused increased physical endurance and decreased urinary dermatan sulfate/chondroitin sulfate ratios. Changes in growth parameters, cardiac, respiratory, visual, auditory findings, and joint mobility were not significant. All patients and parents reported out an increased quality of life, which were not correlated with clinical results. The most prevalent mutation was p.L321P, accounting for 58.8% of the mutant alleles and two novel mutations (p.G79E and p.E390 K) were found. ERT was a safe but expensive treatment for MPS VI, with mild benefits in severely affected patients. Early treatment with ERT is mandatory before many organs and systems are involved.

Abstract
Abstract
RNA-seq has become the most popular method for transcriptome analysis and is widely used to study gene expression, detect mutations, fusion transcripts, alternative splicing, and post-transcriptional modifications. It is becoming the method of choice to detect alterations in diseases, especially cancer, to provide insights on the various molecular pathways perturbed by changes in the transcriptome and study their implications. As RNA-seq is being adopted in molecular diagnostics and biomarker identifications, the need for good quality, reproducible library preparation methods using very low amounts of RNA input, or precious clinical samples, is increasing. To address these challenges, we have developed a strand-specific RNA-seq library preparation method that retains information about which strand of DNA is transcribed, from as low as 5 ng total RNA input. Strand specificity is important for correct annotation of genes, identification of antisense transcripts with potential regulatory roles, and accurate determination of gene expression levels in the presence of antisense transcripts. Enhanced sensitivity to detect transcripts with even coverage across their length offers a non-biased approach for accurate quantification of transcript levels.
Methods: Enriched poly-A mRNA or ribo-depleted RNA (Universal Human Reference RNA) was used to make libraries with our strand specific library preparation method. Library quality and quantity were analyzed on an Agilent Bioanalyzer, pooled at equimolar ratio and sequenced on Illumina’s Nextseq 500. Paired end reads were mapped to a human reference genome (hg19) using Hisat2 and sequencing metrics were calculated using Picard's RNA-seq Metrics and RSeqC tools. Transcript abundance was measured using Salmon and the Ensembl GRCh38 CDS sequences.
Results: Libraries prepared with our streamlined method using inputs that range from 5ng to 1ug show greater than 98% directionality at all input levels. GC content analysis, gene body coverage and gene expression correlation are similar for all inputs tested (5ng to 1ug), even though input amounts vary by over three orders of magnitude. These consistent results are recapitulated with the spiked-in ERCC controls at all inputs.
Conclusions: Our library preparation method is streamlined and can be used for a wide range of input RNA without any major modifications to the protocol, making it an easy to follow, convenient method for RNA-seq library preparation. In addition, our method has increased sensitivity and specificity, especially for low-abundance transcripts, reduced PCR duplicates and sequence bias, delivering high quality strand-specific data even for low input RNA. Finally, our method is compatible with both poly A-tail enriched and ribosomal RNA depleted samples, and is amenable to large-scale library construction and automation.

Abstract
To dissect the role of immunogenetics in allergy and asthma, we performed a phenome-wide association study in 974 Turkish children selected from a cross-sectional study conducted using ISAAC (International Study of Asthma and Allergies in Children) Phase II tools. We investigated 9 loci involved in different immune functions (ADAM33, ADRB2, CD14, IL13, IL4, IL4R, MS4A2, SERPINE1, and TNF) with respect to 116 traits assessed through blood tests, hypertonic saline challenge tests, questionnaires, and skin prick tests. Multiple associations were observed for ADAM33: rs2280090 was associated with reduced MEF240% (i.e., the ratio of Mean Expiratory Flow after 240s of hypertonic saline inhalation with respect to the age- and ancestry-matched reference value) and with an increased risk of allergic bronchitis (p = 1.77*10−4 and p = 7.94*10−4, respectively); rs3918396 was associated with wheezing and eczema comorbidity (p = 3.41*10−4). IL4 rs2243250 was associated with increased FEV240 (Forced Expiratory Flow Volume after 240s of hypertonic saline inhalation; p = 4.81*10−4) and CD14 rs2569190 was associated with asthma diagnosis (p = 1.36*10−3). ADAM33 and IL4 appeared to play a role in the processes linked to allergic airway inflammation and lung function. Due to its association with wheezing and eczema comorbidity, ADAM33 may also be involved in the atopic march.

Abstract
The aim of this study was to evaluate the effects of aliskiren, direct renin inhibitor, as an antioxidant and tissue protective agent and evaluate the molecular, biochemical, and histopathological changes in experimental ischemia and ischemia/reperfusion injury in rat ovaries. Forty-eight female rats were randomly divided into eight groups: in Group 1, only sham operation was performed. Group 2 received 100 mg/kg aliskiren and sham operated. In Group 3, 3 h-period of bilateral ovarian ischemia was applied. Group 4 received a 3-h period of ischemia followed by 3 h of reperfusion. Groups 5 and 6 received 50 and 100 mg/kg, respectively, of aliskiren and bilateral ovarian ischemia was applied (after a 3-h period of ischemia, both ovaries were surgically removed). To Groups 7 and 8, 50 and 100 mg/kg of aliskiren were administered, respectively, and the induction of ischemia was performed. At the end of a 3-h period of ischemia, bilateral vascular clips were removed, and 3 h of reperfusion continued. After the experiments, IL-1β, IL-6, TNF-α, and iNOS mRNA expressions and SOD, GSH, MDA, renin, and angiotensin-II levels were determined and histopathological changes were examined in rat ovaries. Aliskiren treatment normalized excessive changes in cytokine and oxidative stress markers in both ischemia and ischemia/reperfusion injury. Histopathologically, treatment with aliskiren ameliorated the development of ischemia and/or ischemia/reperfusion tissue injury. This study concluded that aliskiren treatment is effective in reversing ischemia and/or ischemia/reperfusion induced ovary damage via the improvement of oxidative stress, reduction of inflammation, and suppression of the renin-angiotensin aldosterone system.

Abstract
Abstract
Immune sequencing allows for the study of complex immunological diseases by sequencing millions of V(D)J combinations from B-cell antibody and T-cell receptors. The popularity of this technique has increased due to recent throughput and read length improvements in next-generation sequencing technologies. However, structural and sequence complexities of antibody genes have made reliable targeting approaches challenging.
We have developed and optimized a method for accurate sequencing of full-length immune gene repertoires of B-cells and T-cells. The method uses a unique barcoding scheme specifically designed to tag every mRNA molecule with a unique identifier (UID) so that all PCR copies of each mRNA fragment can be collapsed into a single consensus sequence. This makes the assay extremely accurate, by resolving PCR bias and sequencing errors as well as allowing quantitative digital molecule counting.
Immune sequencing libraries were generated from total RNA extracted from Peripheral Blood Mononuclear Cells in duplicate from a single patient. The use of UIDs enabled absolute quantification of starting RNA molecules present in the original sample and therefore accurate ranking of the antibody clone abundance, by avoiding the bias incorporated by PCR or sequencing when total reads only were measured. Using the same sequencing method, tumor samples were analyzed for abundance of expanded clones via grouping clones by V gene, J gene and CDR3 similarity and ranking by mRNA abundance. Additionally, the use of isotype-specific primers (IgM, IgD, IgG, IgA and IgE) enabled measurement of the heavy chain isotype proportions within the samples. Further, alignment of full-length heavy chain antibody sequences generated using this method to germline genes from reference databases enabled quantitation of the mutation level of each antibody sequence, thereby providing information on the overall maturity and mutational profile of the sample repertoire.

Abstract
Immunogenes (i.e., genes related to the immune system and its functions) are involved in the predisposition to numerous traits and their variation contributes to the phenotypic variability observed among human groups. Turkish population presents particular genetic features since its genetic pool is an admixture of European, Middle-Eastern, and Central Asian ancestries. Here, we analyzed the haplotype structure of four immunogenetic loci (i.e., ADAM33; IL13-IL4; IL4R; MS4A2) in 482 subjects from five different regions of Turkey. Genotyping was performed using KASP technology. Turkish data were compared with the haplotype information available from the 1000 Genomes Project Phase 3 (26 human populations from 5 ancestry groups). We did not observe significant differences among Turkish groups. Comparing other ancestries, we identified haplotype similarity of Turkish subjects with European populations in IL13-IL4, IL4R, and ADAM33 loci; and with central Asians in MS4A2 region. Considering loci displaying Turkish-European haplotype similarity (i.e., IL13-IL4, IL4R, and ADAM33), we observed differences between Turkish subjects and northern/western Europeans. Conversely, no significant difference was determined in MS4A2 between Turkish and central Asian populations. Finally, we assessed the haplotypes responsible for the differences between Turkish and European samples and the potential functional effects on the immunogenetic loci investigated.

Abstract
OBJECTIVE Therapeutic hypothermia improves neurologic prognosis after cardiac arrest. The aim of this study was to report clinical experience with intravascular method of cooling in patients with cardiac arrest resulting from ST-segment elevation myocardial infarction (STEMI). METHODS Thirteen patients (11 male, 2 famele; mean age was 39.6±9.4 years) who had undergone mild therapeutic hypothermia (MTH) by intravascular cooling after cardiac arrest due to STEMI were included. Clinical, demographic, and procedural data were analyzed. Neurologic outcome was assessed by Cerebral Performance Category (CPC) score. RESULTS Anterior STEMI was observed in 9 patients. One patient died of cardiogenic shock complicating STEMI. Mean cardiopulmonary resuscitation (CPR) duration and door-to-invasive cooling were 32.9±20.1 and 286.1±182.3 minutes, respectively. Precooling Glasgow Coma Scale score was 3 in 9 subjects. Twelve patients were discharged, 11 with CPC scores of 1 at 1-year follow-up. No major complication related to procedure was observed. CONCLUSION In comatose survivors of STEMI, therapeutic hypothermia by intravascular method is a feasible and safe treatment modality.

Abstract
Background Postoperative atrial fibrillation is common after cardiac surgery. In this study, we aimed to investigate the value of interatrial conduction time for the prediction of early postoperative atrial fibrillation, using intra-operative transoesophageal echocardiography. Methods A total of 65 patients undergoing cardiac surgery in our hospital between January and March 2007 were prospectively evaluated, and 59 patients with sinus rhythm were included in the study. We performed transoesophageal echocardiography on all patients, and intra-operatively measured the interatrial conduction time, as recently described. The patients with episodes of atrial fibrillation during the post-surgery hospitalisation period were defined as group 1 and those without episodes were defined as group 2. Results Mean interatrial conduction time was 74 ± 15.9 ms in group 1 and 54 ± 7.9 ms in group 2. The difference in interatrial conduction time between the two groups was statistically significant (p < 0.05). In this study we found a statistically significant interatrial conduction delay between the groups. Postoperative atrial fibrillation was more frequent in patients with a longer interatrial conduction time. Conclusion Increased interatrial conduction time may cause postoperative atrial fibrillation and it can be measured intraoperatively by transoesophageal echocardiography.

Abstract
The Van cat is a domestic landrace found in the Van province of eastern Turkey. In this study, we aimed to determine the seasonal carriage of dermatophytes in Van cats without clinical lesions. A total of 264 hair specimens were collected from clinically healthy cats in and around the Van Province. Of these samples, 30.3% were obtained in spring, 30.6% in summer, 16.6% in autumn, and 22.3% in winter; 45.1% of samples were from male cats and the rest from female ones. Of the studied cats, 118 were younger than 1 year, 78 were 1-3 years old, and 68 were older than 3 years. The specimens were subjected to direct microscopic examination with 15% potassium hydroxide and cultured on Sabouraud dextrose agar and dermatophyte test medium supplemented with cycloheximide and chloramphenicol. Dermatophyte identification was carried out based on macroscopic and microscopic colony morphology, urease activities, in vitro hair perforation test, growth at 37°C, and pigmentation on corn meal agar. Dermatophytes were isolated from 19 (7.1%) of the 264 specimens examined. The most frequently isolated fungi were Trichophyton terrestre (4.1%), followed by Microsporum gypseum (1.1%), M. nanum (1.1%), and T. mentagrophytes (0.7%), and these fungi may represent a health risk for humans in contact with clinically healthy Van cats. M. canis was not isolated from any of the specimens. Our results show no significant (p>0.05) association between carriage of dermatophytes and the gender of cats. The carriage rate of dermatophytes was high in spring and winter, and the only possible risk factor for infection was age of the animal.

Abstract
OBJECTIVE The objective of this study was to retrospectively analyze the clinical course and postoperative long-term survival of patients diagnosed with isolated left main coronary artery (LMCA) stenosis after surgical revascularization. METHODS A total of 38 patients (27 males, 11 females) who were diagnosed with isolated LMCA stenosis and underwent surgical revascularization were enrolled in the study. Isolated LMCA stenosis was classified into 2 groups: ostial stenosis and nonostial stenosis. Coronary events were defined as death of cardiac origin, the need for a new myocardial revascularization procedure, or the occurrence of myocardial infarction in the course of follow-up. The postoperative assessment period included short- and long-term follow-up. The study endpoint was defined as all-cause mortality. RESULTS Among the 38 patients who participated in the study, 25 suffered from ostial LMCA stenosis. The early postoperative mortality rate before hospital discharge was 2.6%. Median duration of postoperative long-term follow-up was 73.43 months (range: 0.17-187.23). Median duration of long-term follow-up free from coronary events or percutaneous coronary interventions was 73.43 months. Postoperative 2-year survival rate was 97.4%, and 5-year survival rate was 92.1%. The postoperative survival period and period free of coronary events of patients with isolated ostial LMCA stenosis did not differ significantly from those of patients with nonostial stenosis (p=0.801, p=0.970, respectively). CONCLUSION Postoperative short- and long-term prognosis of isolated LMCA stenosis appears good in terms of mortality and coronary event symptoms.

Abstract
BACKGROUND Monocyte count to high-density lipoprotein ratio (MHR) has recently emerged as an indicator of inflammation and oxidative stress in the literature. We aimed to investigate the prognostic value of MHR in patients with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention (PCI). METHODS A total of 513 patients who were hospitalized with diagnosis of acute ST-segment elevation myocardial infarction and treated with primary PCI were retrospectively enrolled in the study. Demographic and clinical data, admission laboratory parameters, and MHR values were recorded. Inhospital major adverse cardiac events (MACE) and mortality were reported as the clinical outcomes. RESULTS Twenty-six patients (5%) died, and MACE was observed in 86 patients (17%) during hospital follow-up. Patients were categorized in 3 groups according to tertiles of admission MHR. The rates of inhospital mortality and MACE were significantly higher in tertile 3 group compared to tertile 1 group (10% vs 1%, 27% vs 11%; P < .01 and P < .01). In multivariate regression analysis, age, sex, presence of Killip 3 or 4, left ventricular ejection fraction, troponin I, C-reactive protein, and increased MHR levels (odds ratio, 1.03; 95% confidence interval, 1.01-1.05; P < .01) independently predicted inhospital mortality; age, presence of Killip 3 or 4, troponin I, and increased MHR levels (odds ratio, 1.02; 95% confidence interval, 1.01-1.04; P < .01) independently predicted MACE. CONCLUSION Admission MHR values were found to be independently correlated with inhospital MACE and mortality after primary PCI.

Abstract
UNLABELLED The incidence of biotinidase deficiency in Turkey is currently one of the highest in the world. To expand upon the information about the biotinidase gene (BTD) variations in Turkish patients, we conducted a mutation screening in a large series (n = 210) of probands with biotinidase deficiency, using denaturing high-performance liquid chromatography and direct DNA sequencing. The putative effects of novel mutations were predicted by computational program. Twenty-six mutations, including six novels (p.C143F, p.T244I, c.1212-1222del11, c.1320delG, p.V457L, p.G480R) were identified. Nine of the patients were symptomatic at the initial clinical assessment with presentations of seizures, encephalopathy, and lactic acidemia. The most common mutation in this group of symptomatic patients was c.98-104 del7ins3. Among the screened patients, 72 have partial and 134 have profound biotinidase deficiency (BD) of which 106 are homozygous for BTD mutations. The common mutations (p.R157H, p.D444H, c.98-104del7ins3, p.T532M) cumulatively accounted for 72.3% of all the mutant alleles in the Turkish population. CONCLUSION The identification of common mutations and hot spot regions of the BTD gene in Turkish patients is important for mutation screening in the Turkish population and helps to ascertain carriers, may have impact on genetic counseling and implementing prevention programs.

Abstract
AIM To determine the accuracy of international warfarin pharmacogenetic algorithms developed on large multiethnic cohorts (comprising more than 1000 subjects) to predict therapeutic warfarin doses in Turkish patients. MATERIALS & METHODS We investigated two Turkish warfarin-treated cohorts: patients with no history of hemorrhagic or thromboembolic event and patients with major and life-threatening hemorrhagic events. RESULTS International pharmacogenetic algorithms showed good performances in predicting the therapeutic dose of patients with no history of bleedings, but they did not significantly detect the incorrect warfarin dose of patients with major and life-threatening hemorrhagic events. CONCLUSION Although genetic information can predict the therapeutic warfarin dose, the accuracy of the international pharmacogenetic algorithms is not sufficient to be used for warfarin screening in Turkish patients.

Abstract
Reactivation of androgen receptor (AR) may drive recurrent prostate cancer in castrate patients. Ack1 tyrosine kinase is overexpressed in prostate cancer and promotes castrate resistant xenograft tumor growth and enhances androgen target gene expression and AR recruitment to enhancers. Ack1 phosphorylates AR at Tyr-267 and possibly Tyr-363, both in the N-terminal transactivation domain. In this study, the role of these phosphorylation sites was investigated by characterizing the phosphorylation site mutants in the context of full length and truncated AR lacking the ligand-binding domain. Y267F and Y363F mutants showed decreased transactivation of reporters. Expression of wild type full length and truncated AR in LNCaP cells increased cell proliferation in androgen-depleted conditions and increased colony formation. However, the Y267F mutant of full length and truncated AR was defective in stimulating cell proliferation. The Y363F mutant was less severely affected than the Y267F mutant. The full length AR Y267F mutant was defective in nuclear translocation induced by androgen or Ack1 kinase. The truncated AR was constitutively localized to the nucleus. Chromatin immunoprecipitation analysis showed that it was recruited to the target enhancers without androgen. The truncated Y267F AR mutant did not exhibit constitutive nuclear localization and androgen enhancer binding activity. These results support the concept that phosphorylation of Tyr-267, and to a lesser extent Tyr-363, is required for AR nuclear translocation and recruitment and DNA binding and provide a rationale for development of novel approaches to inhibit AR activity.

Abstract
BACKGROUND The interval between the peak and the end of the T wave (Tp-e interval) on 12-lead ECG is a measure of transmural dispersion of repolarization and may be related to malignant ventricular arrhythmias. The objective of this study was to investigate whether the Tp-e interval predicts in-hospital and long-term mortality in patients with ST-segment elevation myocardial infarction (STEMI) undergoing a primary percutaneous coronary intervention (pPCI). METHODS This study included 488 consecutive patients with STEMI treated with pPCI. Electrocardiograms were obtained after pPCI and the Tp-e interval was measured in leads without ST-segment elevation. RESULTS There were 46 (9.4%) deaths in the population, with a mean follow-up time of 21.1±10.2 months. The Tp-e interval was associated with not only in-hospital ventricular tachycardia/fibrillation, target vessel revascularization, and death but also long-term target vessel revascularization and death. Furthermore, the Tp-e interval measured using the tail method was found to be a significant predictor of long-term mortality in multivariable Cox analyses [odds ratio 1.018, 95% confidence interval (1.004-1.033)]. Findings were similar in the Tp-e interval and the heart rate-corrected Tp-e interval (cTp-e). CONCLUSION Tp-e and cTp-e measured using the tail method were found to be predictors of both in-hospital and long-term mortality.

Abstract
OBJECTIVE Predictive factors of damage to the Fallopian tube may guide the treatment for patients with tubal pregnancy. The purpose of this study was to evaluate the predictive value of ultrasonographic findings in patients affected by ampullary pregnancy for the determination of the depth of trophoblastic infiltration into the tubal wall on histological examination. MATERIAL AND METHODS 38 patients with ampullary pregnancy undergoing salpingectomy were enrolled into the study. The patients were divided into two subgroups depending on their transvaginal sonography (TVS) findings; either an ectopic gestational sac containing an embryo with cardiac activity or those with a tubal ring. The ampullary pregnancies were histologically classified according to the depth of infiltration of trophoblastic tissue into the tubal wall as follows: stage I: limited to mucosa; stage II: extension to the muscularis layer; stage III: complete infiltration of the tubal wall with or without rupture of the serosa. The association between findings on TVS and stage of trophoblastic invasion, serum beta-human chorionic gonodatropin (β-hCG) levels was evaluated. RESULTS Although there was no significant difference among two groups in terms of histological stage of trophoblastic infiltration (p = 0.257), patients in whom an embryo with cardiac activity had been identified were found to have higher percentage of stage II (47.8%) or stage III (8.7%) invasion. However, there was a significant difference in serum β-hCG levels on the day of surgery among the two groups (p = 0.028). CONCLUSIONS Ultrasonographic aspect of ampullary pregnancy is associated with depth of trophoblastic infiltration into the tubal wall and serum β-hCG levels.

Abstract
Many consortia and international projects have investigated the human genetic variation of a large number of ethno-geographic groups. However, populations with peculiar genetic features, such as the Turkish population, are still absent in publically available datasets. To explore the genetic predisposition to health-related traits of the Turkish population, we analyzed 34 genes associated with different health-related traits (for example, lipid metabolism, cardio-vascular diseases, hormone metabolism, cellular detoxification, aging and energy metabolism). We observed relevant differences between the Turkish population and populations with non-European ancestries (that is, Africa and East Asia) in some of the investigated genes (that is, AGT, APOE, CYP1B1, GNB3, IL10, IL6, LIPC and PON1). As most complex traits are highly polygenic, we developed polygenic scores associated with different health-related traits to explore the genetic diversity of the Turkish population with respect to other human groups. This approach showed significant differences between the Turkish population and populations with non-European ancestries, as well as between Turkish and Northern European individuals. This last finding is in agreement with the genetic structure of European and Middle East populations, and may also agree with epidemiological evidences about the health disparities of Turkish communities in Northern European countries.
