Article Synopsis
  • Bypass surgery is a common treatment for moyamoya disease, and the study evaluates the effectiveness of antiplatelet therapy (APT) in improving clinical outcomes post-surgery.
  • A systematic review analyzed data from five studies involving 903 patients, revealing that APT significantly improved bypass vessel patency and reduced transient ischemic events, while offering better functional outcomes.
  • However, APT showed no significant differences in the rates of postoperative strokes, seizures, or cerebral hemorrhages compared to those not receiving APT.

Most cancers re-activate telomerase to maintain telomere length and thus acquire immortality. Activating telomerase promoter mutations are found in many cancers, including melanoma. However, it is unclear when and if telomerase is strictly required during tumorigenesis.

The gene associated with the retinoid-IFN-induced mortality-19 (GRIM-19) protein is a regulator of a cell death regulatory protein that inhibits STAT3, which is a critical transcription factor for interleukin (IL)-17-producing T (Th17) cells and a key integrator of extracellular matrix accumulation in systemic sclerosis (SSc). This protein is also a component of mitochondrial complex I, where it directly binds to STAT3 and recruits STAT3 to the mitochondria via the mitochondrial importer Tom20. In this study, the role of GRIM19 and its relationship with STAT3 in SSc development was investigated using a murine model of SSc.

Article Synopsis
  • The study aimed to investigate the antibacterial effects of plasma-activated NaCl solution (PAN) on harmful bacteria like E. coli O157:H7, Salmonella Typhimurium, and Listeria monocytogenes, while also testing its use as a brine solution for mackerel.
  • PAN was created by treating different concentrations of NaCl solutions with plasma for varying times, resulting in a product with enhanced bactericidal properties compared to conventional plasma-activated water (PAW) and plasma-activated glycerol (PAG).
  • Results showed that higher NaCl levels in PAN improved its antibacterial effectiveness, causing cell membrane damage and increased oxidative stress in bacteria, significantly reducing microbial counts on mackerel without compromising

Background: Nervous necrosis virus (NNV) poses a severe threat to the aquaculture industry, particularly infecting fish fry with devastating mortality rates and inflicting heavy economic losses. Traditional detection methods, such as cell culture and conventional RT-PCR, are not only time-consuming and require specialized laboratory facilities but also hard to eliminate contamination. Rapid and accurate on-site detection methods in aquaculture settings are crucial for effective control of NNV outbreaks in fish farms.

siRNA therapeutics are emerging novel modalities targeting highly specific mRNA via RNA interference mechanism. Its unique pharmacokinetics (PKs) and pharmacodynamics (PDs) are significant challenges for clinical use. Furthermore, naked siRNA is a highly soluble macromolecule with a negative charge, making plasma membrane penetration a significant hurdle.

Cerebral Microbleeds (CMBs) are chronic deposits of small blood products in the brain tissues, which have explicit relation to various cerebrovascular diseases depending on their anatomical location, including cognitive decline, intracerebral hemorrhage, and cerebral infarction. However, manual detection of CMBs is a time consuming and error-prone process because of their sparse and tiny structural properties. The detection of CMBs is commonly affected by the presence of many CMB mimics that cause a high false-positive rate (FPR), such as calcifications and pial vessels.

Microlens array (MLA), through which all the sub-beams are focused, is widely used in multi-electron-beam systems. In this work, based on the differential algebraic (DA) method, we propose an approach in calculating the high-order aberrations for both axial and off-axial microlenses, considering the multipole fields that are introduced by the neighborhood structures in MLA, as well as the rotationally symmetric field. To perform the DA calculation, the electric fields of the microlenses are analyzed by using the azimuthal Fourier analysis and the Fourier-Bessel series Expansion.

Article Synopsis
  • The text discusses how graphene-based van der Waals heterostructures can manipulate spin-orbit coupling (SOC) through proximity effects, emphasizing the importance of understanding features near the Dirac point and the introduction of a unique "radial Rashba SOC."
  • It presents a method to differentiate between conventional Rashba SOC and radial Rashba SOC, utilizing large-scale magnetotransport calculations like transverse magnetic focusing and Dyakonov-Perel spin relaxation to reveal distinct experimental signatures.
  • Additionally, the study proposes a way to estimate the Rashba angle using magnetic field responses and explores the effects of Dresselhaus SOC, hinting at potential applications in radial superconducting diodes.

Lycium barbarum is a type of "medicine-food homology" whose geographical origin has attracted strong interest from consumers due to different regional quality characteristics. A sophisticated OPLS-DA model to verify Lycium barbarum origin was developed using 266 samples gathered from five cultivars in two regions between 2020 and 2022, which was based on 67 indices, including nutrients, bioactives, elements and stable isotopes. Twelve variables (fructose, δH, glucose, tartaric acid, Mo, Na, Sr, His, Phe, Mn, Lys and Rb) were selected to refine models that could distinguish Lycium barbarum origin without being impacted by cultivar or year.

This study explores the enhancement in magnetic and photoluminescence properties of Mn-doped (CdSe) nanoclusters, significantly influenced by the introduction of paramagnetic centers through doping, facilitated by optimized precursor chemistry and precisely controlled surface ligand interactions. Using a cost-effective and scalable synthesis approach with elemental Se and NaBH (Se-NaBH) in n-octylamine, we tailored bonding configurations (Cd-O, Cd-N, and Cd-Se) on the surface of nanoclusters, as confirmed by EXAFS analysis. These bonding configurations allowed for tunable Mn-doping with tetrahedral coordination, further stabilized by hydrogen-bonded acetate ligands, as evidenced by C NMR and IR spectroscopy.

Article Synopsis
  • Single-oxidant slurries used in chemical and mechanical polishing of 4H-SiC crystals struggle to achieve both high material removal rates (MRR) and excellent surface quality.
  • A new method employing a double oxidant slurry containing alumina, potassium permanganate, and potassium persulfate was developed, resulting in an MRR of 1045 nm/h and a surface roughness (Sa) of 0.33 nm, significantly outperforming single oxidant methods.
  • The CMP mechanism involves initial oxidation of the Si-C bonds on the wafer, followed by further oxidation and subsequent removal of oxidation layers through the mechanical action of alumina, paving the way for improved SiC device performance.
