Background And Purpose: Early identification of malignant cerebral edema (MCE) in patients with acute ischemic stroke is crucial for timely interventions. We aimed to identify regions critically associated with MCE using the Alberta Stroke Program Early Computed Tomography Score (ASPECTS) to evaluate the association between location-specific-net water uptake (NWU) and MCE.

Materials And Methods: This multicentre, retrospective cohort study included patients with acute ischemic stroke following large anterior circulation occlusion.

Lignin represents a significant source of aromatic hydrocarbons in the natural world. The production of high-value chemicals from lignin has the great potential to effectively address the issue of fossil energy scarcity. In this study, complex sulfides of nickel‑cobalt bimetallic catalysts were prepared via hydrothermal synthesis and subsequently employed in the catalytic hydrogenolysis of CO bonds present in lignin.

The efficient hydrogenolysis of CO ether bonds in lignin is the key for producing bio-oil and high-value chemicals. In this work, we synthesized a series of Ni-MOF-derived porous carbon spheres anchored Ni catalysts (Ni/C-x-T) with different metal/ligand molar ratios and calcination temperatures through solvothermal and carbothermal reduction method, and evaluated their catalytic transfer hydrogenolysis (CTH) performance for lignin model compounds using isopropanol as H-donor. The Ni/C-2-400 catalyst exhibited the excellent CTH performance, affording almost 100 % conversion of 2-phenoxy-1-phenylethanol even at a low reaction temperature of 120 °C.

While senescent cells have detrimental roles in several contexts, they are highly heterogeneous. p16 highly expressing senescent cells have been reported to exert beneficial functions in wound healing. Here we use Xenium spatial transcriptomics to identify a distinct p21 highly expressing senescent population induced on wounding, with a pro-inflammatory profile.

Article Synopsis
  • Cardiac T2 mapping is a diagnostic tool that faces challenges with spatial resolution, which may limit its effectiveness in detecting small heart lesions.
  • This study presents a new cardiac T2 mapping technique using the SCC-LLRT algorithm, validated by tests on both phantoms and human participants, showing improved spatial resolution without increased acquisition time.
  • Results indicated that the new method significantly reduces artifacts and noise while enhancing overall image quality compared to traditional imaging techniques, leading to better-defined images of the myocardium.

  • A multicenter randomized controlled trial in China investigated the impact of adding coronary CT-derived fractional flow reserve (CT-FFR) to routine coronary CT angiography (CCTA) on the need for invasive coronary angiography (ICA) and major adverse cardiovascular events (MACE) in patients with suspected coronary artery disease (CAD).
  • The study involved 5,297 participants, showing that the CCTA plus CT-FFR group had a lower ICA rate (10.0%) compared to the CCTA alone group (12.4%) over a 90-day follow-up.
  • While MACE rates were similar between groups, the CCTA plus CT-FFR approach resulted in fewer cardiac events after one year (0.5%

  • The study focuses on the enzyme MAT2A, which is linked to synthetic lethality in cancers that lack methylthioadenosine phosphorylase, found in about 15% of cancer cases.
  • A new MAT2A inhibitor named SCR-7952 shows strong anti-tumor effects in lab tests and animal studies without raising bilirubin levels.
  • SCR-7952 works well in combination with specific types of PRMT5 inhibitors, enhancing their effectiveness by disrupting PRMT5 function and affecting splicing of the FANCA gene, suggesting its potential as a treatment for -deleted cancers.

A key challenge in aging research is extending lifespan in tandem with slowing down functional decline so that life with good health (healthspan) can be extended. Here, we show that monthly clearance, starting from 20 months, of a small number of cells that highly express p21 (p21) improves cardiac and metabolic function and extends both median and maximum lifespans in mice. Importantly, by assessing the health and physical function of these mice monthly until death, we show that clearance of p21 cells improves physical function at all remaining stages of life, suggesting healthspan extension.

  • The evolution of SARS-CoV-2 variants highlights the need for multivalent vaccines, leading to the development of SCTV01E, a tetravalent COVID-19 vaccine targeting variants Alpha, Beta, Delta, and Omicron BA.1.
  • A double-blind placebo-controlled trial showed SCTV01E had a vaccine efficacy of 69.4% against COVID-19 seven days post-vaccination, with higher efficacy rates in preventing symptomatic and all infections at 14 days.
  • The vaccine demonstrated a significant neutralizing antibody response against Omicron BA.5 and had mild reactogenicity, indicating its potential effectiveness against emerging SARS-CoV-2 variants.

Immune checkpoint inhibition targeting the PD-1/PD-L1 pathway has become a powerful clinical strategy for treating cancer, but its efficacy is complicated by various resistance mechanisms. One of the reasons for the resistance is the internalization and recycling of PD-L1 itself upon antibody binding. The inhibition of lysosome-mediated degradation of PD-L1 is critical for preserving the amount of PD-L1 recycling back to the cell membrane.

Broadly neutralizing antibodies are proposed as therapeutic and prophylactic agents against HIV-1, but their potency and breadth are less than optimal. This study describes the immunization of a llama with the prefusion-stabilized HIV-1 envelope (Env) trimer, BG505 DS-SOSIP, and the identification and improvement of potent neutralizing nanobodies recognizing the CD4-binding site (CD4bs) of vulnerability. Two of the vaccine-elicited CD4bs-targeting nanobodies, G36 and R27, when engineered into a triple tandem format with llama IgG2a-hinge region and human IgG1-constant region (G36×3-IgG2a and R27×3-IgG2a), neutralized 96% of a multiclade 208-strain panel at geometric mean ICs of 0.

Two-dimensional molybdenum borides (MBenes) comprise a new class of 2D transition metal borides that exhibit potential photonics applications. Recently, the synthesis of individual single-layer MoBT (T = O, F, OH) MBene sheets has been realized, which attracted considerable attention in optoelectronics. However, there is still a lack of understanding and regulation of the photophysical processes of MoBT MBene.

Chemoselective hydrogenation of carbonyl in unsaturated aldehydes is a significant process in the chemical industry, in which the development of aqueous-phase reaction systems as a substitution to organic ones is challenging. Herein, we report Ir atomic cluster catalysts anchored onto WO nanorods a reduction treatment at various temperatures (denoted as Ir/WO-T, = 200, 300, 400, and 500 °C), which accelerates the chemoselective hydrogenation of carbonyl groups in aqueous solutions. The optimal catalyst Ir/WO-300 exhibits exceptional activity (TOF value: 1313.

N-linked glycosylation is an essential and highly conserved co- and post-translational protein modification in all domains of life. In humans, genetic defects in N-linked glycosylation pathways result in metabolic diseases collectively called Congenital Disorders of Glycosylation. In this modification reaction, a mannose rich oligosaccharide is transferred from a lipid-linked donor substrate to a specific asparagine side-chain within the -N-X-T/S- sequence (where X ≠ Proline) of the nascent protein.

Background: Susceptibility-weighted imaging (SWI) and T1/T2 mapping can be used to detect reperfusion intramyocardial hemorrhage (IMH) in ST-segment elevation myocardial infarction (STEMI) patients. However, the sensitivity and accuracy of the SWI and T1/T2 mapping sequences were not systematically compared. The study aimed to evaluate image quality and diagnostic performance of SWI in patients with IMH, compared with T1/T2 mapping.

The effects of zirconium doping on the thermodynamic, electronic, and optical properties of tin dioxide are investigated by using density functional theory calculations combined with the cluster expansion method. In the whole composition range, the formation enthalpies of all structures are positive, indicating that SnO-ZrO is an immiscible system and the ZrSnO alloy has a tendency of phase separation at low temperature. The phase diagram of ZrSnO ternary alloy shows that the critical temperature is 979 K, which means that when the growth temperature of ZrSnO crystal is higher than the critical temperature, it is possible to realize the full-component solid solution.
