AV standardizes the verification of laboratory results, improves turnaround time (TAT), detects errors in the total test process, and enables effective use of laboratory staff. In this study, we aimed to evaluate the outcomes of implementing the AV in a tertiary hospital. Methods The study was performed in Gazi University Health Research and Application Hospital, Core Biochemistry Laboratory, between August 2017 and October 2019. Step by step, AV algorithms were designed and implemented via middleware for 29 clinical biochemistry tests. A comprehensive validation was performed before the AV system was run. Initially, AV system was tested with datasets and simulated patients (dry testing). Next, samples that may violate AV rules were tested anonymously with no-named trial barcodes (wet testing). Finally, validation of the system was performed with real patients, while the AV was running in the background but not active (i.e., while the manual verification was still going on). After all these steps were successful, the system was started. Results In the daytime, AV rates were ≥75 % for 23 of 29 tests. In night-shift, AV rates were ≥70 % for 16 of 25 tests. Report-based performance was found 26 % for daytime. TAT in the daytime decreased after AV implementation. Conclusions Although this is the first time we have implemented the AV, a significant percentage of the tests have been verified. However, approaches that will increase the percentage of report-based verification will enhance the efficiency of autoverification.","PeriodicalId":23344,"journal":{"name":"Turkish Journal of Biochemistry","volume":"59 3","pages":"626 - 633"},"PeriodicalIF":0.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139268707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Elevated levels of hepcidin in renal failure contribute to the development of anemia. We aimed to evaluate the association between hepcidin and inflammation in hemodialysis patients and how dialysis affects hepcidin levels. Methods Hepcidin clearance with hemodialysis was investigated by measuring hepcidin concentrations by enzyme-linked immunosorbent assay (ELISA) method before and after hemodialysis of 40 patients in a single dialysis session. Hemogram parameters and ferritin, iron, total iron binding capacity (TIBC), and C-reactive protein (CRP) were measured and evaluated their relations with predialysis hepcidin levels. Results Hepcidin levels decreased significantly with dialysis treatment (p=0.009). Median hepcidin concentration before dialysis was measured as 330 ng/mL (83–459) and post-dialysis median hepcidin concentration was 250 ng/mL (94–384). There was a significant correlation between predialysis hepcidin levels and ferritin (r=0.858, p<0.001), TIBC (r=−0.451, p=0.004), and MCV (r=0.384, p=0.016). It was found that increases in ferritin levels in time were positively correlated with hepcidin before dialysis. Conclusions We think that understanding the removal of the hepcidin by dialysis, which causes a decrease in the amount of iron available in the anemia, is important in managing future therapy.","PeriodicalId":23344,"journal":{"name":"Turkish Journal of Biochemistry","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74104098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies have shown that miR-564 and miR-718 are either downregulated or upregulated in various cancers. The purpose of this study was to examine the levels of expression of miR-564 and miR-718 in colorectal cancer (CRC) patients’ tumor and non-tumor tissues. Methods The study group consisted of tumor and non-tumor tissues obtained from a total of 80 CRC patients. The expression levels of miRNAs were determined using quantitative Real-Time Polymerase Chain Reaction (RT-qPCR). Additionally, using bioinformatics analysis, the transcription factors (TFs) that are associated with miR-564 and miR-718 were identified as well as the GO (Gene Ontology) and KEGG (Kyoto Encyclopedia of Genes and Genomes) enrichment pathway analysis of these miRNAs. Results According to the findings of RT-qPCR, both miR-564 and miR-718 expression levels were significantly downregulated in CRC (p<0.001). There was a statistically significant correlation between the expression levels of miR-564 and miR-718 (p=0.006). Both miR-564 and miR-718 regulated TFs including E2F1, HIFIA, BRD4, KDM2B, ESR1, MYC, PHF8, RUNX1, TCF12 and YY1. According to KEGG analysis, miR-564 and miR-718 were associated with Hippo and FoxO signaling pathways, respectively (p<0.05).

The pigment epithelium-derived factor (PEDF) is a protein that is one of the most potent angiogenesis inhibitors. The effect of blood PEDF concentration on DRP formation remains unclear. The present study aimed to determine whether the plasma concentration of PEDF is effective on the appearance of DRP. Methods The present study consisted of 62 patients with diabetes mellitus and 20 healthy participants. The patient group included 28 patients with non-proliferative DRP, 13 with proliferative DRP, and 21 diabetic patients without DRP. The PEDF levels in patient serum samples were detected through the ELISA method. The body mass index of the participants was calculated. Results Serum PEDF levels of diabetic patients (1.533 ± 0.233 μg/mL) were found to be lower (2.163 ± 0.343 μg/mL) than healthy participants (p=0.002). The PEDF levels were similar in the DRP and non-DRP groups (p=0.337). The plasma PEDF level decreased along with the progression of DRP (p=0.001). Conclusions The PEDF concentration in the blood decreases along with the increase of DRP grade. Decreased blood concentration of PEDF may be important to predict microvascular complications. Agents containing PEDF may be used intraocularly/systemically for therapeutic purposes to prevent vascular complications of diabetes in the near future.","PeriodicalId":23344,"journal":{"name":"Turkish Journal of Biochemistry","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87819288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has several complex mechanisms for evading human immunity. The objective of the study was to examine the secretory immunoglobulin A (sIgA) mediated immune response in saliva to detect P. aeruginosa in pulmonary tuberculosis. Methods The infection with P. aeruginosa was categorized according to the Leeds criteria in the final 86 individuals who were proven to have pulmonary tuberculosis by polymerase chain reaction. Levels of serum immunoglobulin G (IgG) and sIgA which are specific to P. aeruginosa were measured using the method of ELISA. Results Patients in the “free of infection (patients who were infected with P. aeruginosa in the lower respiratory tract at the beginning of the study later became negative)” and “intermittent colonized (patients who were infected with P. aeruginosa throughout the study)” groups had substantially higher median baseline sIgA levels in saliva and a much greater proportion of sIgA positive than patients who were never colonized (patients who were found to be P. aeruginosa negative throughout the study) (p=0.038). Median baseline IgG level was 10.7 (1.7–145.0), 8.3 (2.5–22.9), and 6.7 (3.3–17.1) for the patients categorized as “intermittent colonization”, “free of infection” and “never colonized”, respectively. After 3 years of study, sIgA level was found in significant high level among the patients with infection of P. aeruginosa (p=0.003).

Exogenous miRNAs are unstable in the plasma due to degradation by nucleases; hence, choosing a harmless and effective delivery mode is crucial in the quest for miRNA-based therapeutics to treat neurological disorders. This review aims to shed light on the emerging role of nanotechnology-based approaches using miRNAs to treat neurodegenerative disorders. Nanotechnology encompasses a broad spectrum of applications, one of which is its role in developing nanoscale drug delivery systems. Nanotechnology-based drug delivery systems have attracted the attention of researchers due to the superiority of this mode over conventional treatment systems in terms of their favorable attributes such as bio-compatibility, bio-degradability, extremely small size, and the ability to cross the blood-brain barrier.

Left untreated, it leads to acquired immunodeficiency syndrome (AIDS). Antiretroviral therapy (ART) is used to control HIV infection. Etravirine (ETR) is an important non-nucleoside reverse transcriptase inhibitor (NNRTI) utilized in the treatment of HIV. Low-level viremia (LLW) is a serious clinical condition, and the underlying mechanisms remain incompletely understood. The aim of our study is to analyze and elucidate the resistance status of Lys104Gln, Lys102Gln, Lys101Arg-Lys104Arg, Ser191Phe, Ile94Leu-Lys104Arg, Lys104Glu-His235Leu, Ala98Ser and Val179Ile mutations using in-silico methods, which are identified as low-level viremic strains, because their resistance status to ETR is unknown. Methods Homology modeling was performed using the Swiss Model program. Molecular docking of ETR with the reverse transcriptase (RT) enzyme was conducted using the CB-Dock program developed by AutoDock Vina. Protein-ligand interaction analysis was carried out using the protein-ligand interaction profiler (PLIP). Results A98S and V179I mutations altered the physicochemical properties of the region, resulting in changes to the conformational structure of the NNRTI hydrophobic pocket compared to the wild-type and consequently decreased docking scores. Conclusions Based on the evaluation of literature data and in-silico analyses, it is believed that A98S and V179I mutations may alter the conformational structure of the hydrophobic pocket where ETR binds, potentially resulting in low-level resistance against ETR.","PeriodicalId":23344,"journal":{"name":"Turkish Journal of Biochemistry","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74018421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a lifelong disease, asthma has episodes. Inflammation continues to occur in the clinical remission of asthma. It can be difficult to diagnose childhood asthma, especially in clinical remission. We hypothesized that some cytokines secreted to nasal fluid from the airway during inflammation might help diagnose clinical remission of asthma. Moreover, sampling nasal fluid is an easy and non-invasive procedure, so it may be a preferable sampling method.
