Bio‐Based Multilayer Composites Based on Blended Electrospun Fibers and Luffa Cylindrica for Enhanced Low‐Frequency Noise Absorption

Journal of Polymer Science, Volume 64, Issue 7, Page 1568-1582, 1 April 2026.
Bio‐based multilayer composites consisting of Luffa Cylindrica and electrospun microfibers exhibit enhanced sound absorption, shifting peak performance towards lower frequencies. The multilayer configuration improves acoustic wave dissipation, providing a tunable and sustainable solution for urban and traffic‐related noise mitigation.

Frontiers in the Management of Orthopaedic Periprosthetic Joint Infection

Journal of Orthopaedic Research, Volume 44, Issue 2, February 2026.
ABSTRACT Periprosthetic joint infection (PJI) is a devastating complication of total joint arthroplasty (TJA), one of the most frequently performed surgical procedures worldwide. Management of acute PJI commonly involves debridement, antibiotics, and implant retention (DAIR), though failure rates remain high due to antibiotic‐tolerant biofilms. Chronic

Genus zero PALF structures on the Akbulut-Yasui plugs

Osaka Journal of Mathematics, 2019
We construct a genus zero PALF structure on each of plugs introduced by Akbulut and Yasui and describe the monodromy as a positive factorization in the mapping class group of a fiber. We also examine the monodromies of PALFs on a certain pair of compact Stein surfaces such that one is obtained by applying a plug twist to the other.

A Novel PCK1 Gene Variant Associated With Cytosolic Phosphoenolpyruvate Carboxykinase Deficiency: Two Siblings With Different Clinical Presentations

JIMD Reports, Volume 67, Issue 1, January 2026.
ABSTRACT Cytosolic phosphoenolpyruvate carboxykinase (PEPCK‐C) deficiency is a rare autosomal recessive gluconeogenesis disorder caused by variants in the PCK1 gene. Clinically, PEPCK‐C deficiency is characterized by recurrent episodes of fasting‐induced hypoglycemia, liver dysfunction, and seizures, with the first hypoglycemic episode typically ...
