Correlations between Cardiovascular Risk Factors and Ventricular Arrhythmias Following Primary Percutaneous Coronary Intervention in Patients with ST-Elevation Myocardial Infarction.

Background: Ventricular arrhythmias (VAs), which result from acute myocardial infarction and revascularization, are preventable causes of sudden cardiac death. This study aimed to determine the incidence, types, and risk factors of VAs in patients with ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention (PCI).

Methods: This cross-sectional study was conducted at the cardiology department of a tertiary care cardiac center in Zanjan, Iran.

Randomized Study of the Effects of Zinc, Vitamin A, and Magnesium Co-supplementation on Thyroid Function, Oxidative Stress, and hs-CRP in Patients with Hypothyroidism.

Hypothyroidism can occur due to deficiencies in micronutrients such as zinc, magnesium, and vitamin A. The aim of this study was to determine the effects of supplementation with these micronutrients on thyroid function, oxidative stress, and hs-CRP levels in patients with hypothyroidism. In a randomized double-blind, placebo-controlled trial with two parallel groups, 86 hypothyroid patients aged 20-65 were allocated to receive daily supplementation with either: (intervention group, n = 43) one 30 mg zinc gluconate capsule per day, one 250 mg magnesium oxide tablet per day, and one 25,000 IU vitamin A capsule twice/week for 10 weeks or (placebo group, n = 43) placebo capsules and tablets as above for 10 weeks.

Efficient Media for High Lipase Production: One Variable at a Time Approach.

Background: Lipase enzymes have applications in a wide range of industries. A crucial determining factor of industrial prices of these enzymes is the culture media composition that is constantly under review by researchers. In this work, for maximum lipase production by , culture media compositions were optimized using ″one variable at a time″ strategy.

Idiopathic pulmonary fibrosis is strongly associated with productive infection by herpesvirus saimiri.

Idiopathic pulmonary fibrosis is a fatal disease without effective therapy or diagnostic test. To investigate a potential role for γ-herpesviruses in this disease, 21 paraffin-embedded lung biopsies from patients diagnosed with idiopathic pulmonary fibrosis and 21 lung biopsies from age-matched controls with pulmonary fibrosis of known etiology were examined for a series of γ-herpesviruses' DNA/RNA and related proteins using in situ hybridization and reverse transcriptase-polymerase chain reaction (RT-PCR)-based methods. We detected four proteins known to be in the genome of several γ-herpesviruses (cyclin D, thymidylate synthase, dihydrofolate reductase, and interleukin-17) that were strongly co-expressed in the regenerating epithelial cells of each of the 21 idiopathic pulmonary fibrosis cases and not in the benign epithelia of the controls.
