Drug Development.

Background: The DL-3-n-butylphthalide (NBP), a multi-target neuroprotective drug, improving cognitive impairment in patient with vascular cognitive impairment has been confirmed. The efficacy of NBP in patients with cognitive impairment due to Alzheimer's disease (AD) remains unknown. This study aimed to evaluate the efficacy and safety of NBP in patients with mild cognitive impairment (MCI) due to AD though a clinical randomized controlled trail.

Drug Development.

Background: Effective early intervention of mild cognitive impairment (MCI) is the key for preventing dementia. However, there is currently no drug for MCI. As a multi-targeted neuroprotective agent, butylphthalide has been demonstrated to repair cognition in patients with vascular cognitive impairment, and has the potential to treat MCI due to Alzheimer's disease (AD).

The stereoselective bioactivity and mechanism of indoxacarb against Spodoptera frugiperda.

Background: Indoxacarb, a type of chiral pesticide, is used to control Lepidoptera insects. Most studies had focused on the environmental behavior and selective toxicity of indoxacarb enantiomers, and the mechanism behind its selective biological activity against target organisms is not well understood.

Results: Spodoptera frugiperda was selected as the target insect.

A Novel Competing Endogenous RNA Network Reveals Potential Mechanisms and Biomarkers of Chemoresistance in Lung Adenocarcinoma.

Platinum resistance is a common cause of chemotherapy failure in lung adenocarcinoma (LUAD). Competing endogenous RNAs (ceRNAs), which function by competitively binding to miRNAs, can influence drug response. However, the regulatory mechanisms of ceRNAs underlying chemoresistance in LUAD remain largely unknown.

Symmetrical and asymmetrical surface structure expansions of silver nanoclusters with atomic precision.

Controlling symmetrical or asymmetrical growth has allowed a series of novel nanomaterials with prominent physicochemical properties to be produced. However, precise and continuous size growth based on a preserved template has long been a challenging pursuit, yet little has been achieved in terms of manipulation at the atomic level. Here, a correlated silver cluster series has been established, enabling atomically precise manipulation of symmetrical and asymmetrical surface structure expansions of metal nanoclusters.

Madecassoside mitigates acute myocardial infarction injury by activating the PKCB/SPARC signaling pathway.

The current treatments and drugs of myocardial infarction (MI) remain insufficient. In recent years, natural products have garnered significant attention for their potential in treating cardiovascular diseases due to their availability and lower toxicity. Saponins, in particular, showed promising effects for cardiac protection.

Inherent asymmetry of Rpd3S coordinates its nucleosome engagement and association with elongating RNA polymerase II.

The Rpd3S histone deacetylase complex has a crucial role in genomic integrity by deacetylating transcribed nucleosomes following RNA polymerase (Pol) II passage. Cryo-EM studies highlight the importance of asymmetrical Rco1-Eaf3 dimers in nucleosome binding, yet the interaction dynamics with nucleosomal substrates alongside elongating Pol II are poorly understood. Here we demonstrate the essential function of the Rco1 N-terminal intrinsically disordered region (IDR) in modulating Pol II association, in which K/R mutations within the Rco1 IDR impair interaction of Rpd3S with the C-terminal domain (CTD) of Rpb1, without affecting nucleosome recognition or complex integrity.

Organocatalytic enantioselective synthesis of double S-shaped quadruple helicene-like molecules.

Helicene-shaped molecules are compelling chemical structures with unique twisted helical chirality and remarkable properties. Although progress occurs in the catalytic asymmetric synthesis of helicene (-like) molecules, the enantioselective synthesis of multiple helicenes, especially four or higher helicity, is still challenging and has yet to be achieved. Herein, we report an organocatalytic [4 + 2] cycloadditions to achieve double S-shaped quadruple helicene-like molecules with high enantioselectivity (up to 96% e.

Holocellulose nanofibrils biomimetic entrapment of liquid metal enable ultrastrong, tough, and lower-voltage-driven paper device.

Integrating liquid metal (LM) with wood fibers for flexible paper electronics is intriguing yet extremely challenging due to poor mechanical performance. Here, we disclose a hemicellulose trapping strategy to achieve exceptional ultrastrong and tough LM-based paper electronics. Holocellulose nanofibrils (HCNFs) with hemicellulose retention of approximately 20 % are found to effectively entrap nanoscale LM within the fibril network, analogous to spider silk capturing small water droplets.

Oligosaccharide-assisted resolution of holothurian fucosylated chondroitin sulfate for fine structure and P-selectin inhibition.

Fucosylated chondroitin sulfate (FCS) from Holothuria mexicana (FCS) was selected for investigation because of its intriguing branch features. Selective β-eliminative depolymerization and the bottom-up assembly were performed to unravel that FCS consisted of a {D-GlcA-β1,3-D-GalNAc} backbone and branches of alternating Fuc (55 %) and D-GalNAc-α1,2-L-Fuc (45 %), the highest proportion of disaccharide branch reported to date. In branches, sulfation could occur at every free -OH site except O-3 of GalNAc, being the most complex and various structure features of natural FCS.
