Cardioprotective effect of S-adenosyl L-methionine due to antioxidant and anti-inflammatory properties on isoproterenol-induced chronic heart failure in Wistar rats.

Objectives: The development and progression of chronic heart failure (CHF), hypertrophy, and remodeling strongly correlate with myocardial inflammation and oxidative stress. S-adenosylmethionine (SAMe), available as a dietary supplement, exerts anti-inflammatory and antioxidant effects. Previous reports show that by regulating angiogenesis and fibrosis, S-adenosyl-L-methionine improves ventricular remodeling.

Safety and Clinical Outcomes of a Complete "Minimalist" Left Atrial Appendage Occlusion Pathway.

The standard approach to catheter based left atrial appendage occlusion (LAAO) involves trans-esophageal echocardiography (TEE) guided screening and placement, and procedural general anesthesia requiring overnight stay. In pursuit of improved patient experience and reduced cost, streamlined approaches in each phase of care have been explored. However, the safety and clinical outcomes for a completely protocolized minimalist approach utilizing computed tomography angiogram (CTA), intracardiac echocardiography (ICE), conscious sedation, and same-day discharge are lacking.

CD spectra reveal the state of G-quadruplexes and i-motifs in repeated and other DNA sequences.

The B-DNA of the genome contains numerous sequences that can form various noncanonical structures including G-quadruplex (G4), formed by two or more stacks of four guanine residues in a plane, and intercalating motif (i-motif [iM]) formed by alternately arranged C-C pairs. One of the easy yet sensitive methods to study G4s and iMs is circular dichroism (CD) spectroscopy, which generates characteristic G4 and iM peaks. We have analyzed and compared the effects of various environmental factors including pH, buffer composition, temperature, flanking sequences, complimentary DNA strands, and single-stranded DNA binding protein (SSB) on the CD patterns of G4s and iMs generated by two groups of DNA molecules, one containing tandem repeats of GGGGCC and CCCCGG from the C9ORF72 gene associated with amyotrophic lateral sclerosis and frontotemporal dementia, and the second containing polyG/polyC clusters from oncogene promoter-proximal regions without such tandem repeats.

Engineered PVA-tamarind gum-based biocomposite for sustained ophthalmic delivery of moxifloxacin: Effect of nanocellulose on physicochemical, mechanoelectrical and permeation kinetics.

Widely used polysaccharide-based films in ophthalmic drug delivery have major limitations of inadequate mechanical strength, poor electrical conductivity, and insufficient ocular drug permeability. Moxifloxacin (MFX) biocomposite film of adequate mechanoelectrical properties was developed for sustained ophthalmic drug delivery. Nanocellulose (NC) incorporated (2.
