[ 1 ] - Association between the synonymous variant organic cation transporter 3 (OCT3)-1233G>A and the glycemic response following metformin therapy in patients with type 2 diabetes
Objective(s): Organic cation transporter 3 (OCT3) as a high-capacity transporter contribute to the metabolism of metformin. The present study was conducted to determine the genotype frequencies of the variant OCT3-1233G>A (rs2292334) in patients with newly diagnosed type 2 diabetes (T2D) and its relationship with response to metformin. Materials and Methods: This study included 150 patients wit...
[ 2 ] - Prevalence of EPIYA motifs in Helicobacter pylori strains isolated from patients with gastroduodenal disorders in northern Iran
Background: Cytotoxin-associated gene A (CagA)-positive strains of Helicobacter pylori are associated with gastroduodenal diseases. Evidences have suggested that the type of H pylori CagA EPIYA motifs may be associated with specific disorders (i.e., gastritis, peptic ulcer, or gastric cancer). We investigated the prevalence of different EPIYA motifs (A, B, C, or D) in H. pylori strains is...
[ 3 ] - Hepatotoxicity and ALT/AST Enzymes Activities Change in Therapeutic and Toxic Doses Consumption of Acetaminophen in Rats
Acetaminophen (APAP) poisoning is the most common drug intoxication, which often leads to acute liver failure (ALF). In this study, the effects of different doses of APAP on aminotransferases (AST and ALT) and liver pathological lesions were assessed in young rats. 32 male albino Wistar rats were randomly selected and divided into eight groups. In case groups, three groups after one hour, and 3...
[ 4 ] - Association between prostate specific antigen change over time and prostate cancer recurrence risk: a joint model
Background: Prostate specific antigen (PSA) is an important biomarker to monitor patients after treated with radiation therapy (RT). The aim of this study is to evaluate the relationship between the PSA data and prostate cancer recurrence using the joint modeling. Methods: This historical cohort study was performed on 422 prostate cancer patients. Inclusion criteria included: patients with loc...
[ 5 ] - Sperm Retrieval in Patients with Klinefelter Syndrome: A Skewed Regression Model Analysis
Background The most common chromosomal abnormality due to non-obstructive azoospermia (NOA) is Klinefelter syndrome (KS) which occurs in 1-1.72 out of 500-1000 male infants. The probability of retrieving sperm as the outcome could be asymmetrically different between patients with and without KS, therefore logistic regression analysis is not a well-qualified test for this type of data. This stud...
