Abstract
The transcription factor p73 is a member of the p53 tumor suppressor gene family and one of the key regulators of apoptosis. TP73 gene encodes two protein isoforms classes with diverse functions, TAp73 and DNp73, and TAp73 expression in tumor tissues is altered. Unlike the TP53 gene, TP73 is not mutated in cancers. Here, we sought to explore the expression of p73 isoforms across eight major cancer types using the publicly available data deposited at the GDC data portal and the TSVdb database. Our results showed that TAp73α is overexpressed in breast invasive carcinoma, stomach adenocarcinoma, lung squamous cell carcinoma, colon adenocarcinoma, and esophageal carcinoma tumors, whereas the expression of DNp73 isoforms is downregulated in breast invasive carcinoma (DNp73α,β,γ), Prostate Adenocarcinoma (DNp73β), Lung Adenocarcinoma (DNp73α), Lung Squamous Cell Carcinoma (DNp73α) tumors. In summary, this study revealed that TAp73α has higher expression than the DNp73 isoforms in several cancer types.

Abstract
AIM The aim of the current study was to evaluate the index of Cardiac Electrophysiological Balance (iCEB) in hospitalized COVID-19 patients receiving Hydroxychloroquine / azithromycin (HCQ / AZ) combination therapy to determine the susceptibility to ventricular arrhythmia among these patients. METHOD Sixty-seven COVID-19 patients admitted to the ward were included in the study. Electrocardiograms (ECGs) were obtained from all patients before the initiation of treatment and on treatment day 5. QT/QRS (iCEB) and QTc/QRS (iCEBc) ratios were calculated. RESULTS QRS, QT and QTc intervals were significantly prolonged on day 5 measurements compared to pre-treatment period (p <0.05). Overall, mean iCEB was 3.6±0.4 before treatment and 3.8±0.4 on day 5 in the study population (p <0.001). Considering the iCEBc values, a significant increase was observed in patients receiving HCQ/AZ treatment compared to pre-treatment period (4.1±0.5 vs 4.4±0.6; p <0.001). CONCLUSIONS To the best of our knowledge, this was the first study to investigate iCEB and iCEBc parameters in patients with COVID-19 on HCQ/AZ therapy. In this study, we demonstrated significantly increased iCEB and iCEBc values following HCQ/AZ treatment in COVID-19 patients. iCEB and iCEBc may serve as a noninvasive, simple, and novel biomarker for detecting increased pro-arrhythmia risk in COVID-19 patients (Tab. 3, Fig. 3, Ref. 36).

Abstract
PURPOSE Fibroblast growth factor-21 (FGF-21) is a member of fibroblast growth factor family. Both growth hormone (GH) and FGF-21 take place in the regulation of glucose and lipid metabolism. We aimed to investigate FGF-21 levels in acromegaly which is characterized by excess GH levels and is associated with comorbidities and altered body composition. METHODS We studied 43 subjects (21 females and 22 males, mean age of 50.0 ± 12.8) with acromegaly. The control group consisted of 40 gender- and age-matched subjects (25 females and 15 males, mean age of 48.8 ± 8.8). Acromegaly patients were classified into two groups; active acromegaly (AA; n = 26) and controlled acromegaly (CA; n = 17). Metabolic, anthropometric and laboratory values of subjects were recorded. FGF-21 level was measured by ELISA assay. RESULTS Median FGF-21 levels were significantly higher in acromegaly group compared to control group (85.5 vs. 59.0 pg/mL, p = 0.02, respectively). In the multiple regression model, FPG, A1c, HOMA-IR, glucose intolerance, BMI, visceral fat, hs-CRP, presence of hypertension, dyslipidemia and acromegaly were included as independent variables to explain variability of plasma FGF-21 levels in whole study group. The presence of acromegaly was the only determinant of increased FGF-21 levels in the whole study group (β coefficient = 0.253, p = 0.006). CONCLUSION FGF-21 levels were increased significantly in acromegaly group. Increased FGF-21 levels were significantly and independently associated with the state of acromegaly. Acromegaly may also be a FGF-21 resistance state independent from insulin resistance, glucose intolerance, obesity, hypertension and dyslipidemia.

Abstract
Species identification of sandflies is mainly performed according to morphological characters using classical written identification keys. This study introduces a new web-based decision support tool (sandflyDST) for guiding the morphological identification of sandfly species present in Anatolia and mainland Europe and classified in the Phlebotomus and Sergentomyia genera (both: Diptera: Psychodidae). The current version of the tool consists of 111 questions and 36 drawings obtained from classical written keys, and 107 photographs for the quick and easy identification of 26 species of the genus Phlebotomus and four species of the genus Sergentomyia. The tool guides users through a decision tree using yes/no questions about the morphological characters of the specimen. The tool was applied by 30 individuals, who then completed study questionnaires. The results of subsequent analyses indicated that the usability (x‾SUSScore=75.4) and users' level of appreciation (86.6%) of the tool were quite high; almost all of the participants considered recommending the tool to others. The tool may also be useful in training new entomologists and maintaining their level of expertise. This is a dynamic tool and can be improved or upgraded according to feedback. The tool is now available online at http://parasitology.ege.edu.tr/sandflyDST/index.php.

Abstract
AIM The expression differences of SCN8A (which encodes type VIII alpha subunit of voltage gated sodium channel) and NDUFC2 (which encodes C2 subunit of Complex I enzyme in oxidative phosphorylation) genes were evaluated in paired colorectal cancer (CRC) tissues which was relied on our partial transcriptome analysis data in cancer cell lines. MATERIALS AND METHODS A total of 62 paired tissues of CRC patients (34 male, 28 female) were included in the study. The mRNA levels of SCN8A and NDUFC2 genes were determined by using real-time PCR (qRT-PCR and semiquantitative PCR). RESULTS SCN8A gene expression level was significantly lower in tumor tissues (p = 0.0128) and in the patients with the age below 45 years (p = 0.0049). There were also meaningful relationships between the gender, grade of CRC, tumor location, histopathological classification, and SCN8A expression. There was no NDUFC2 differential expression. However, the tumors taken from right colon had significantly lower NDUFC2 expression. CONCLUSION Although the voltage gated sodium channels (VGSCs) and Complex I (CI) were associated to a number of diseases including different types of cancers, the different subunits of CI and individual members of VGSCs seem to be cancer type-specific in varying proportions.

Abstract
UNLABELLED Colorectal cancer (CRC) is the most common cancer of the gastrointestinal tract. Different factors are responsible for the development of CRC. Transient Receptor Potential (TRP) which is an important component of calcium channel is associated with several pathological conditions like cancer, neurodegenerative and cardiovascular diseases. Thirty members of the family of TRP ion channel in mammals have been determined till now. The aim of this study is to investigate TRPM, TRPV and TRPC gene expression levels in tumor tissues of CRC patients and to analyze the relationship of expression in tumor tissue of CRC with other known prognostic factors. MATERIAL AND METHODS In this study, 93 CRC patients were included. The level of TRP gene expression in paraffin blocks of normal and cancerous colorectal tissue samples were studied at the level of mRNA with Real-time PCR. RESULTS The mRNA expression level of TRPV3, TRPV4, TRPV5, TRPM4 and TRPC6 genes in 37 female and 56 male patients diagnosed with CRC was revealed lower in tumor tissue as compared to normal tissue (p < 0.05). No statistically significant differences of mRNA expression levels of other TRP genes were found. CONCLUSIONS TRP gene family like TRPV3, TRPV4, TRPV5, TRPM4 and TRPC6 may be thought as potential genes contributing to tumorigenesis as their expression decreases in CRC as compared to normal tissues.

Abstract
BACKGROUND The selection of appropriate rectal cancer treatment is a complex multi-criteria decision making process, in which clinical decision support systems might be used to assist and enrich physicians' decision making. OBJECTIVE The objective of the study was to develop a web-based clinical decision support tool for physicians in the selection of potentially beneficial treatment options for patients with rectal cancer. METHODS The updated decision model contained 8 and 10 criteria in the first and second steps respectively. The decision support model, developed in our previous study by combining the Analytic Hierarchy Process (AHP) method which determines the priority of criteria and decision tree that formed using these priorities, was updated and applied to 388 patients data collected retrospectively. Later, a web-based decision support tool named corRECTreatment was developed. The compatibility of the treatment recommendations by the expert opinion and the decision support tool was examined for its consistency. Two surgeons were requested to recommend a treatment and an overall survival value for the treatment among 20 different cases that we selected and turned into a scenario among the most common and rare treatment options in the patient data set. RESULTS In the AHP analyses of the criteria, it was found that the matrices, generated for both decision steps, were consistent (consistency ratio<0.1). Depending on the decisions of experts, the consistency value for the most frequent cases was found to be 80% for the first decision step and 100% for the second decision step. Similarly, for rare cases consistency was 50% for the first decision step and 80% for the second decision step. CONCLUSIONS The decision model and corRECTreatment, developed by applying these on real patient data, are expected to provide potential users with decision support in rectal cancer treatment processes and facilitate them in making projections about treatment options.
