Article Synopsis
  • Edoxaban, a non-vitamin K oral anticoagulant, is approved for stroke prevention in atrial fibrillation (AF) patients in many Asian countries, but its long-term effectiveness and safety had limited data in Taiwan prior to this study.
  • The Global ETNA-AF registry analyzed two-year outcomes in Taiwan and three other Asian countries, revealing that edoxaban users in Taiwan were generally older with lower kidney function but showed comparable low rates of clinical events across regions.
  • The study concluded that despite some variations in patient characteristics, the low rates of cardiovascular death and major bleeding events indicate that edoxaban is effective and safe for routine clinical use among AF patients in Taiwan and other Asian countries.

Photodependent processes, including circadian rhythm, autophagy, ubiquitination, neddylation/deneddylation, and metabolite biosynthesis, profoundly influence microbial pathogenesis. Although a photomorphogenesis signalosome (COP9/CSN) has been identified, the mechanism by which this large complex contributes to the pathophysiological processes in filamentous fungi remains unclear. Here, we identified eight CSN complex subunits in the rice blast fungus and functionally characterized the translocon subunits containing a nuclear export or localization signal (NES/NLS).

Isw2 proteins, ubiquitous across eukaryotes, exhibit a propensity for DNA binding and exert dynamic influences on local chromosome condensation in an ATP-dependent fashion, thereby modulating the accessibility of neighboring genes to transcriptional machinery. Here, we report the deletion of a putative MoISW2 gene, yielding substantial ramifications on plant pathogenicity. Subsequent gene complementation and chromatin immunoprecipitation sequencing (ChIP-seq) analyses were conducted to delineate binding sites.

Background: Sodium-glucose cotransporter 2 inhibitors (SGLT2i) and dipeptidyl peptidase-4 inhibitors (DPP4i) are important second-line treatments for patients with type 2 diabetes mellitus (T2DM). Patients taking SGLT2i have favorable cardiovascular outcomes via various mechanisms, including autonomic nervous system (ANS) modulation. This study aimed to use neuro-electrocardiography (neuECG) to test the effects of SGLT2i or DPP4i on the ANS.

Article Synopsis
  • Subclinical atrial fibrillation (AF) increases risks of developing clinical AF, stroke, and cardiovascular death; researchers aimed to test if closed loop stimulation (CLS) could reduce atrial high-rate episodes (AHREs) in pacemaker patients compared to conventional dual-chamber rate-adaptive pacing (DDDR).
  • A study with 1,210 patients showed that those using CLS had a lower incidence of the primary endpoint (first AHRE lasting ≥6 min, stroke, or TIA) compared to DDDR over a 3-year period, particularly effective in patients without atrioventricular block or AF history.
  • The findings suggest that dual-chamber CLS significantly reduces AHRE occurrence, highlighting its potential benefits for patients
