Background: The hippocampus is associated with mood disorders, and the activation of quiescent neurogenesis has been linked to anxiolytic effects. Near-infrared (NIR) light has shown potential to improve learning and memory in human and animal models. Despite the vast amount of information regarding the effect of visible light, there is a significant gap in our understanding regarding the response of neural stem cells (NSCs) to NIR stimulation, particularly in anxiety-like behavior.

Background: Low back pain is a major disorder that causes disability and is strongly associated with intervertebral disc degeneration (IDD). Because of the limitations of contemporary interventions, stem cell transplantation (SCT) has been increasingly used to regenerate degenerative discs. Nevertheless, analyses of high-impact papers in this field are rare.

The third, stepped-wedge, cluster-randomized, Intensive Care Bundle with Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial (INTERACT3), has shown that a goal-directed multi-faceted Care Bundle incorporating protocols for the management of physiological variables was safe and effective for improving functional recovery in a broad range of patients with acute intracerebral hemorrhage (ICH). The INTERACT3 Care Bundle included time- and target-based protocols for the management of early intensive lowering of systolic blood pressure (SBP, target <140mmHg), glucose control (target 6.1-7.

Flexible and diverse manipulation of electromagnetic (EM) waves in half space (reflection or transmission) has facilitated strong aspiration toward full-space wave control. However, it remains challenging to achieve independent amplitude and phase control, which seriously hinder the real-world applications. Herein, an innovative strategy of trifunctional metasurface is proposed to independently and simultaneously manipulate the amplitude and phase of circular polarized waves in full space.

Background And Aims: Although existing evidence suggests that arterial stiffness and obesity impact cardiovascular health, limited studies have been conducted to explore the association between brachial-ankle pulse wave velocity (baPWV), obesity-related indices, and the risk of atherosclerotic cardiovascular disease (ASCVD).

Methods And Results: The study participants were among those who completed the baPWV measurement at the second follow-up examination (during 2018-2020) of the Rural Chinese Cohort Study. Logistic regression models were employed to calculate odds ratios (ORs) and 95 % confidence intervals (CIs) of the 10-year incident risk score of ASCVD associated with baPWV and obesity-related indices.

At present, there lacks a definitive pharmaceutical intervention or therapeutic approach for diabetes-associated cognitive impairment. Herein, we delved into the impact of electroacupuncture on cognitive function in high-fat diet/streptozocin (HFD/STZ)-induced T2DM mice and underlying mechanisms. Hippocampal insulin resistance was determined by western blot analysis.

The titanium-based lithium ion sieve (HTO), renowned for its exceptional adsorption performance and cyclic stability, was utilized in addressing the global shortage of lithium resources. However, the recovery and reuse efficiency of HTO in powder form is relatively low, which limits its application in industrial fields. To address this issue, this study utilized carboxymethyl cellulose (CMC) as the principal matrix material, while polyvinyl alcohol (PVA) played a dual function as both matrix and crosslinker, negating the necessity for supplementary crosslinking materials.

Background: Cardiovascular disease (CVD) remains a significant public health challenge in China. This study aimed to project the burden of CVD from 2020 to 2030 using a nationwide cohort and to simulate the potential impact of various control measures on morbidity and mortality.

Methods: An agent-based model was employed to simulate annual CVD incidence and mortality from 2021 to 2030.

Article Synopsis
  • * A comparison of sour jujube 'Qingjiansuanzao' and cultivated jujube 'Junzao' revealed that sour jujube has higher PA levels that decrease as the fruit develops.
  • * Research identified specific genes, ZjLAR and ZjANR, that promote PA production; overexpressing these genes in both jujube and other plants increased PA content, providing insights for improving jujube fruit quality.

  • - The study investigates the role of LGALS3BP as a potential biomarker to differentiate between four subtypes of idiopathic inflammatory myopathies (IIM): dermatomyositis (DM), anti-synthetase syndrome (ASS), immune-mediated necrotizing myopathy (IMNM), and sporadic inclusion body myositis (sIBM), alongside healthy controls (HCs).
  • - Using bioinformatics and enzyme-linked immunosorbent assay (ELISA), the researchers found that serum LGALS3BP levels varied significantly across the IIM subtypes and were linked to clinical features and inflammatory markers, particularly indicating a higher prevalence of interstitial lung disease (ILD) in patients with elevated levels.

A better understanding of how sympathetic nerves impact pancreatic function is helpful for understanding diabetes. However, there is still uncertainty and controversy surrounding the roles of sympathetic nerves within the pancreas. To address this, we utilize high-resolution imaging and advanced three-dimensional (3D) reconstruction techniques to study the patterns of sympathetic innervation and morphology in the islets of adult wild-type (WT) and diabetic mice.

This study demonstrates the controllable switching of skyrmion helicity using spin-orbit torque, enhanced by thermal effects. Electric current pulses applied to a [Pt/Co]/Ru/[Co/Pt] multilayer stripe drive skyrmions in a direction opposite to the current flow. Continuous pulsing results in an unexpected reversal of skyrmion motion.

Article Synopsis
  • Cells react to DNA damage through responses like DNA repair or programmed cell death (apoptosis), but the factors influencing these choices are not well understood.
  • The protein ANGPTL8, which is usually involved in lipid metabolism, also plays a key role in guiding cells towards apoptosis instead of repair when faced with DNA damage.
  • ANGPTL8 interacts with a protein called PARP1, promoting apoptosis by enhancing PARP1's accumulation on damaged DNA, while its own levels decrease after DNA damage to prevent excessive toxicity.

  • The study aimed to evaluate whether protamine administration increases pulmonary artery pressures (PAPs) in patients undergoing specific heart surgeries, like pulmonary artery reconstruction and unifocalization.
  • Conducted as a retrospective study using data from a pediatric heart center, researchers analyzed outcomes after protamine and calcium were administered, revealing significant increases in PAP at intervals post-administration.
  • The findings indicated that protamine led to a notable rise in PAP after surgery, while coadministering calcium did not result in a greater increase.
