Heat shock protein 70 (HSP70)-interacting proteins (HIPs) have been studied in animals. HIPs perform diverse cellular functions, ranging from alleviating stress to suppressing the formation of insoluble protein, but how their orthologs function in plants is less known. This study shows that Arabidopsis HIP is a cytosolic and nuclear protein associated with HSP70.

Article Synopsis
  • - Sepsis leads to high mortality and is often complicated by acute kidney injury (AKI), which causes rapid decline in kidney function in patients.
  • - The study investigates how inhaling high concentration hydrogen affects septic mice with AKI, finding that it can reduce inflammation, improve kidney function, and increase survival rates without causing hypoxia.
  • - Hydrogen therapy appears to work by enhancing mitochondrial function, specifically by inhibiting mitochondrial fission and promoting fusion and biogenesis, alongside improving antioxidant enzyme activity and reducing inflammatory factors.

We investigated the association between cerebral small vessel disease (CSVD) and ipsilateral leptomeningeal collateral (LMC) status in patients with symptomatic intracranial atherosclerotic stenosis (sICAS). In 108 patients with 50-99% symptomatic intracranial internal carotid artery or M1 middle cerebral artery stenosis, 4 CSVD imaging markers (lacunes, cerebral microbleeds, enlarged perivascular spaces [EPVSs], and white matter hyperintensities [WMHs]) were assessed in MRI. Score of 0 or 1 was assigned to each marker and added up as a summary CSVD score (ranging 0-4) to reflect an overall CSVD burden.

Article Synopsis
  • Sepsis-associated encephalopathy (SAE) is a serious brain injury linked to sepsis, and this study explores the potential protective effects of inhaling high concentrations (67%) of hydrogen gas (H) on this condition in mice.
  • Researchers induced sepsis in mice and treated them with hydrogen gas, measuring survival rates, cognitive function, and various mitochondrial factors 24 hours post-surgery.
  • The results showed that hydrogen inhalation increased survival, improved memory, reduced inflammation, and promoted better mitochondrial health, suggesting that H may help regulate mitochondrial biogenesis and dynamics in traumatic brain conditions like SAE.

Importance: The China Antihypertensive Trial in Acute Ischemic Stroke II (CATIS-2) suggests that early antihypertensive treatment did not reduce the risk of dependency or death in acute ischemic stroke (AIS), compared with delayed treatment. Single subcortical infarction (SSI) is an important stroke subtype, and the association of antihypertensive timing with clinical outcomes is unclear.

Objective: To investigate the association of early vs delayed antihypertensive treatment with clinical outcomes in patients with SSI, stratified by the presence of parent artery disease (PAD) stenosis.

The fracture mechanism and macro-properties of SVSAC were studied using a novel test system combined with numerical simulations, which included three-point bending beam tests, the digital image correlation (DIC) technique, scanning electron microscopy (SEM), and ABAQUS analyses. In total, 9 groups and 36 specimens were fabricated by considering two critical parameters: initial notch-to-depth ratios (/) and concrete mix components (seawater and volcanic scoria coarse aggregate (VSCA)). Changes in fracture parameters, such as the load-crack mouth opening displacement curve (-CMOD), load-crack tip opening displacement curve (-CTOD), and fracture energy (), were obtained.

As a kind of proteolytic enzyme extracted from , lumbrokinase has been used as an antithrombotic drug clinically. Nevertheless, its potential in anti-cancer, especially in anti-non-small cell lung cancer (NSCLC), as a single form of treatment or in combination with other therapies, is still poorly understood. In this study, we explored the anti-tumor role and the responsive molecular mechanisms of lumbrokinase in suppressing tumor angiogenesis and chemoresistance development in NSCLC and its clinical potential in combination with bevacizumab and chemotherapeutics.

Epigenomic mechanisms are critically involved in mediation of genetic and environmental factors that underlie cancer development. Histone modifications represent highly informative epigenomic marks that reveal activation and repression of gene activities and dysregulation of transcriptional control due to tumorigenesis. Here, we present a comprehensive epigenomic and transcriptomic mapping of 18 tumor and 20 non-neoplastic tissues from non-small cell lung adenocarcinoma patients.

Despite the great promise in the development of biodegradable and ecofriendly air filters by electrospinning of poly(lactic acid) (PLA) nanofibrous membranes (NFMs), the as-electrospun PLA nanofibers are generally characterized by poor electroactivity and smooth surface, challenging the exploitation of electrostatic adsorption and physical interception that are in need for efficient removal of pathogens and particulate matters (PMs). Herein, a combined "electrospinning-electrospray" strategy was disclosed to functionalize the PLA nanofibers by direct anchoring of highly dielectric BaTiO@ZIF-8 nanohybrids (BTO@ZIF-8), conferring simultaneous promotion of surface roughness, electret properties (surface potential as high as 7.5 kV), and self-charging capability (∼190% increase in tribo-output voltage compared to that of pure PLA).

There may be different mechanisms underlying internal (IBZ) and cortical (CBZ) borderzone infarcts in intracranial atherosclerotic stenosis. In 84 patients with symptomatic, 50-99% atherosclerotic stenosis of M1 middle cerebral artery (MCA-M1) with acute borderzone infarcts in diffusion-weighted imaging, we classified the infarct patterns as isolated IBZ (n = 37), isolated CBZ (n = 31), and IBZ+CBZ (n = 16) infarcts. CT angiography-based computational fluid dynamics models were constructed to quantify translesional, post-stenotic to pre-stenotic pressure ratio (PR) in the MCA-M1 lesion.
