Intrinsic Birefringence of Poly (L-lactic acid)

open access: yesSen'i Gakkaishi, 1999
The intrinsic birefringence value of Poly (L-lactic acid) was estimated experimentally for the drawn and annealed fiber, in which almost all of the crystals involved are the α-form. The value 0.030-0.033 was obtained using Stein's formula by substituting the results of structural analysis for highly drawn and annealed samples.

Intelligent Programmable Membrane Nanosponge for Early Virus Blocking

open access: yesAdvanced Science, EarlyView.
A smart programmable nanosponge (ACNPs) displays high‐density viral receptors on its membrane and encapsulates fusion inhibitors to capture virions at the infection source through competitive binding and blocks their entry through protease inhibition for ultra‐early cascade interception. This modular, mucus‐penetrating platform shifts antiviral defence

Restoring Endothelial Mitochondrial Homeostasis With a Bioactive Nanoshield Promotes Vascular Regeneration on Cardiovascular Implants

open access: yesAdvanced Science, EarlyView.
A bioactive poly(citrate‐polyglycol‐procyanidin) (PCGP) nanoshield is developed for cardiovascular implants to restore endothelial mitochondrial homeostasis following vascular injury. By preserving mitochondrial integrity, re‐establishing metabolic balance, and activating PI3K/Akt/eNOS‐NO signaling, the PCGP interface promotes functional endothelial ...

Study of poly (l-lactic acid)/poly (d-lactic acid) stereocomplex as nucleating agent for poly (l- lactic acid) crystallization [PDF]

open access: yes, 2013
Poly (lactic acid) (PLA) is a biodegradable polymer with good renewability and processability. However, it has some drawbacks. The Poly (lactic acid) (PLA) stereocomplex formed via the interaction between optical isomers Poly (L-lactic acid) (PLLA) and ...

Effects of L‐ and D‐ form oligo(lactic acid)s grafted cellulose reinforcement on the thermal properties of poly(L‐lactic acid) composites

open access: yesSPE Polymers
L‐ and D‐ form oligo(lactic acid)s (OLLA and ODLA) grafted α‐cellulose (OLLA‐g‐cellulose and ODLA‐g‐cellulose) were prepared by the graft polycondensation reaction in C6H5CH3 medium at 130°C and 380 mm of mercury pressure.

A Metabolic‐Epigenetic Axis of AARS1/IGF2BP3‐K280 Lactylation Sustains Endometrial Cancer Stemness and Recurrence

open access: yesAdvanced Science, EarlyView.
Lactate‐driven endometrial cancer relapse is mediated by enzymatic protein modification. Elevated lactate levels activate AARS1, which catalyzes K280 lactylation of IGF2BP3, therefore stabilizing HMGA2 mRNA and promoting tumor stemness and recurrence.

Multi‐Tissue Crosstalk Regulating Meniscus Healing Under Inflammation and Physiological Loading

open access: yesAdvanced Science, EarlyView.
Using a novel Meniscus‐on‐a‐chip (MoC) model integrated with a meniscus‐specific bioreactor, this study investigated the roles of multi‐tissue crosstalk that regulates injury, healing, and degeneration of the meniscus injury under inflammation and pathophysiological loading.
