Correlation Between PIK3R1 Expression and Cell Growth in Human Breast Cancer Cell Line BT-474 and Clinical Outcomes.

Background: While mutations in the gene play important roles in human breast carcinogenesis, gene alterations are recognized as actionable mutations for clinical cancer treatment. We aimed to elucidate the role of PIK3R1 in cell proliferation on breast carcinoma and to correlate the PIK3R1 expression with patients' outcome using human tumor tissue arrays.

Methods: Using human BT-474 (estrogen receptor (ER)+/human epidermal growth factor receptor 2 (HER2)-high) breast carcinoma cell line as model, the role of PIK3R1 in cell proliferation was elucidated by knock-down of the gene (ΔPIK3R1) in this cell line.

Temporal trends of prescription rates, oral anticoagulants dose, clinical outcomes and factors associated with non-anticoagulation in patients with incident atrial fibrillation.

Objective: To analyze the temporal trends of oral anticoagulant (OAC) prescription, direct oral anticoagulant (DOAC) dose, clinical outcomes and factors associated with non-anticoagulation in patients with incident atrial fibrillation (AF).

Patients And Methods: During January 1, 2011, to December 31, 2020, a total of 249,107 patients with newly diagnosed AF were identified, and the 1-year risks of ischemic stroke, intracranial hemorrhage (ICH), and all-cause mortality were analyzed.

Results: OAC prescription increased from 22.

Effects of different warm-up methods on 50-meter breaststroke swimming performance.

Purpose: To examine the effects of different warm-up methods on 50 m breaststroke performance in both breaststroke specialists and individual medley swimmers.

Methods: 18 swimmers (breaststroke group: 9, individual medley group: 9) who met the qualification standards for the National Intercollegiate Athletic Games participated in this study. Each participant completed four different warm-up protocols (a conventional 1,400 m warm-up and a 700 m conventional warm-up that integrated tubing-assisted (TA), paddle (PD), or squat (SQ) warm-ups) over four separate days.

Patterns of pharmacological treatment in patients with atrial fibrillation: an analysis from the prospective GLORIA-AF Registry Phase III.

Background: Polypharmacy (i.e., treatment with ≥ 5 drugs) is common in patients with atrial fibrillation (AF) and has been associated with suboptimal management and worse outcomes.

Green Synthesis of Tetrahydropyrazino[2,1-a:5,4-a']diisoquinolines as SARS-CoV-2 Entry Inhibitors.

A class of tetrahydropyrazino[2,1-a:5,4-a']diisoquinoline derivatives were synthesized under environmentally friendly conditions using water as the solvent. The 3-D structures of some synthesized compounds were determined by X-ray diffraction. Since naturally occurring isoquinoline alkaloids have significant antiviral activities against a wide range of viruses, including coronaviruses, the synthesized compounds were assayed for their inhibitory activities against SARS-CoV-2.
