In this study, we aimed to determine the rate of implementation of RLUP in medical biochemistry laboratories, and to contribute to new regulations by collecting the information and opinions of the laboratory experts participating the survey. Methods Thirty questions were uploaded to an online survey tool (SurveyMonkey®, San Mateo, ABD). The first five were descriptive for laboratories. Among the remaining 25 questions, one is open-ended and addresses the various topics encompassed by the project’s scope. Results The questionnaire was completed by 202 medical biochemistry specialists, of whom 82.12 % reported that they did not implement autoverification. 55.65 % defined consultations in Hospital Management Information System (HIMS), but; 70.49 % were not using it actively. 57.69 % of the participants answered, “I agree” to the statement “I think RLUP is feasible”. It was observed that the specialists tried to implement rational laboratory practices partially depending on their laboratory capacity, hospital administration and Laboratory Information Management System (LIMS).

While the potential asymmetric effects of the left and right branches of the vagus nerve remain uncertain, this study aims to investigate the impact of unilateral, bilateral, and atropine interventions on HRV parameters and choline levels within cardiac tissue. Methods 40 male adult Wistar albino rats were randomly assigned to the five groups (each n=8): sham-operated, atropine, right vagotomy, left vagotomy, and bilateral vagotomy. Heart rate variability (HRV) analyses were conducted, and the levels of total choline/acetylcholine in heart tissues were quantified. Statistical analyses were performed to assess the results. Results The bilateral vagotomy and atropine groups exhibited higher heart rates and high frequency power (HF), along with reduced low frequency power (LF). Total power (TP) remained relatively unchanged. In the bilateral vagotomy group, DFAα1 was significantly elevated while DFAα2 was reduced significantly. SD1 and SampEn were significantly lower in both the bilateral vagotomy and atropine groups. Notably, the right vagotomy group displayed significant changes primarily in the 15th minute, particularly in time-domain parameters, HF, TP, and SD1, with a significant increase observed in total choline levels.

Our findings suggest that compensatory hemodynamic recovery, possibly driven by contralateral vagal overactivity, may contribute to these observed results.","PeriodicalId":23344,"journal":{"name":"Turkish Journal of Biochemistry","volume":"11 17","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141700498","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}

The purpose of this study is to identify the molecular pathways in which genes related to RP illness are involved, as well as uncover the biological processes and molecular functions connected with those genes via the use of gene ontology (GO) analysis. Methods Genes associated with RP in the MalaCards Human Diseases database were detected. Twenty genes obtained from the MalaCards Human Diseases database were included in the study for gene ontology analysis via the STRING database. Accordingly, possible interactions between 20 genes were determined through STRING and network enrichment was performed. Results A significant enrichment by gene ontology enrichment analysis was detected in a subset of genes involved in biological processes including cellular response to luteinizing hormone stimulus, negative regulation of fibrinolysis, negative regulation of smooth muscle cell apoptotic process, plasminogen activation, cellular response to follicle-stimulating hormone stimulus. The assay for molecular function determined enrichment of a subset of genes in chemoattractant activity, growth factor activity, heparin binding, sulfur compound binding, growth factor receptor binding. Through the use of KEGG pathways, we were able to identify many molecular processes that contribute to RP, including the AGE-RAGE signaling pathway in diabetic complications, complement and coagulation cascades, fluid shear stress, atherosclerosis. Conclusions Some individuals may have a genetic predisposition to the onset of Raynaud’s phenomenon. Our data showed that it is associated with genes involved in vascular damage and fibrosis, especially in RP.

This study aims to investigate the relationship between PPARG-C161T polymorphism and the risk of ISR, considering clinical features. Methods According to the results of coronary angiography, the patients who had undergone drug-eluting stent implantation were categorized into two groups: ISR (n=116) and non-ISR (n=265). The control group consisted of 140 healthy subjects with asymptomatic for CAD or any systemic disease. PPARG-C161T genotypes were determined using the real-time polymerase chain reaction melting curve analysis. Results T2DM, hypertension, and hyperlipidemia were observed as the main clinical features causing non-ISR and ISR. The 161-CC genotype was associated with an increased risk of ISR compared to both controls (p=0.014) and non-ISR patients (p=0.008). This difference remained statistically significant after multivariate analysis for non-ISR patients (p=0.003) but not for the ISR group. The prevalence of hypertension and hyperlipidemia was higher in ISR patients with T2DM than in non-ISR patients with T2DM (p=0.002 and p=0.009, respectively). Multivariate logistic regression analysis in subgroups based on the presence of T2DM showed that hypertension (p<0.001) was associated with ISR in patients with T2DM. Conclusions This study points out the association between the PPARG 161-CC genotype and the risk of ISR, which also means that the PPARG 161-T allele is protective against ISR. However, this effect could be divergent in the presence of the metabolic components of the restenosis phenotype, especially T2DM.","PeriodicalId":23344,"journal":{"name":"Turkish Journal of Biochemistry","volume":"31 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141340405","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}

Methods We established four distinct rat groups: corn oil (negative control group), 20 % fructose (positive control group), 20 % fructose and 100 mg/kg curc (100 mg/kg curc group), and 20 % fructose and 200 mg/kg curc (200 mg/kg curc group). The ELISA method was used to determine serum insulin levels, an auto-analyzer was used to measure serum glucose levels, and homeostatic model assessment of insulin resistance (HOMA-IR) values were calculated. In the rat’s skeletal muscle and adipose tissues, the ELISA method was used to determine the following parameters: insulin receptor substrate-1 (IRS-1), phosphorylated insulin receptor substrate-1 (p-IRS-1), PI3K, phosphatidylinositol 3,4,5-trisphosphate (PIP3), phosphoinositide-dependent kinases (PDK-1), phosphorylated Akt (p-Akt), AMPK and glucose transporter type 4 (GLUT4) levels. Results The positive control group exhibited a significant increase in serum glucose, insulin, and HOMA-IR levels, confirming the establishment of the insulin resistance model.
