Background: The island sign is a predictor of hematoma expansion and worse outcomes in patients of spontaneous primary intracerebral hemorrhage (ICH). The biological mechanism of the island sign remains unclear, but its presence might be influenced by the underlying vasculopathy related to Apolipoprotein E () genotypes. Therefore, we aimed to research the association between genotypes and the island sign.

The agile Earth observation satellite scheduling problem (AEOSSP) with time-dependent transition time is a combinatorial optimization challenge. Due to its NP-hardness, problem-tailored methods are sensitive to instances and require massive computational overhead. Recently, deep reinforcement learning (DRL) models have shown promise in efficiently addressing the AEOSSP.

Lipase-catalyzed esterification for enhancing oil quality has garnered extensive attention due to its eco-friendly and efficient merits. Nevertheless, during the catalytic esterification process at the oil-water interface to reduce acid value, the immobilized lipase is prone to detachment as a result of continuous mechanical agitation. In this study, inspired by the aerodynamic theory of golf ball surfaces, a novel immobilized enzyme system is designed and fabricated to improve the quality of Antarctic krill oil and prolong its storage time.

This study evaluated the in vitro antioxidant activity and bioactive compound content of mixed-strain lactic acid bacteria-fermented black mulberry juice (FBMJ) and its protective effects against oxidative stress using physicochemical experiments and a cellular oxidative stress model. We also performed preliminary analyses of polysaccharide structures in FBMJ and identified the dynamic changes in the phenolic profiles of FBMJ during the fermentation process. The results indicated that FBMJ polyphenols can improve cell vitality and prevent HO-induced oxidative stress by reducing intracellular reactive oxygen species concentrations and regulating mitochondrial membrane potential.

Background And Purpose: Lobar intracerebral hemorrhage (ICH) is associated with a high risk of recurrence, particularly in elderly patients, where cerebral amyloid angiopathy (CAA) is often the primary cause. Diagnostic markers of CAA-related ICH, including subarachnoid hemorrhage (SAH) and finger-like projection (FLP), have recently been developed. Here, we aimed to explore the associations between SAH, FLP and the risk of ICH recurrence in lobar ICH patients.

Electrocatalytic CO-to-CO conversion with a high CO Faradaic efficiency (FE) at low overpotentials and industrial-level current densities is highly desirable but a huge challenge over non-noble metal catalysts. Herein, graphitic N-rich porous carbons supporting atomically dispersed nickel (NiN-O sites with an axial oxygen) were synthesized (denoted as O-Ni-N-GC) and applied as the cathode catalyst in a CORR flow cell. O-Ni-N-GC showed excellent selectivity with a FE over 92% at low overpotentials ranging from 17 to 60 mV, and over 99% at 80 mV.

Recent studies have unveiled the deep sea as a rich biosphere, populated by species descended from shallow-water ancestors post-mass extinctions. Research on genomic evolution and microbial symbiosis has shed light on how these species thrive in extreme deep-sea conditions. However, early adaptation stages, particularly the roles of conserved genes and symbiotic microbes, remain inadequately understood.

Background: Transcranial direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS) are common non-invasive brain stimulation (NIBS) methods for functional recovery after stroke. Motor imagery (MI) can be used in the rehabilitation of limb motor function after stroke, but its effectiveness remains to be rigorously established. Furthermore, there is a growing interest in the combined application of NIBS with MI, yet the evidence regarding its impact on the recovery of upper limb function after stroke is inconclusive.

With the rapid development of industry, agriculture, and urbanization, various organic pollutants have accumulated in natural water, posing a potential threat to both the ecological environment and human beings, and removing organic pollutants from water is an urgent priority. Piezoelectric techniques, with the advantages of green, simple operation, and high efficiency, are highly sought after in the degradation of environmental organic pollutants. Moreover, combining piezoelectric techniques with advanced oxidation processes (AOPs), photocatalysis, or electrocatalysis can further effectively promote the efficient degradation of target pollutants.

Background: Metronidazole is a first-line antibiotic to treat Helicobacter pylori infections. However, the Clinical Laboratory Standards Institute guidelines recommend against using antimicrobial susceptibility test (AST) to test metronidazole resistance, due to the unreliable predictive power which can result in treatment failure.

Recent studies have shown that aqueous U(VI) ions can be transformed into U(VI) precipitates through electrocatalytic redox reactions for uranium recovery. However, there have been no reports of U(IV) solids, such as UO, using electrochemical methods under ambient conditions since low-valence states of uranium are typically oxidized to U(VI) by O or HO. Here we developed a secondary metal ion-induced strategy for electrocatalytic production of U(IV) solids from U(VI) solutions using a catalyst consisting of atomically dispersed gallium on hollow nitrogen-doped carbon capsules (Ga-N-C).

Removing trace amounts of acetylene (CH) from ethylene (CH)-rich gas mixtures is vital for the supply of high-purity CH to the chemical industry and plastics sector. However, selective removal of CH is challenging due to the similar physical and chemical properties of CH and CH. Here, we report a "single-molecule trap" strategy that utilizes electrostatic interactions between the one-dimensional (1D) channel of a covalent organic framework (denoted as COF-1) and CH molecules to massively enhance the adsorption selectivity toward CH over CH.

Fatty liver injury is a prevalent condition in most farmed fish, yet the molecular mechanisms underpinning this pathology remain largely elusive. A comprehensive feeding trial spanning eight weeks was conducted to discern the potential of dietary chitosan in mitigating the deleterious effects of a high-fat diet (HFD) while concurrently exploring the underlying mechanism. Growth performance, haemato-biochemical capacity, antioxidant capacity, apoptotic/anti-apoptotic gene expression, inflammatory gene expression, and histopathological changes in the liver, kidney, and intestine were meticulously assessed in Nile tilapia.
