Objective: To observe the clinical effect and safety of the warm acupuncture of Mongolian medicine in treatment of insomnia in the elderly, and to explore its underlying brain-gut peptide mechanism.

Methods: Sixty elderly patients with insomnia were randomly divided into a warm acupuncture group and a western medication group, 30 cases in each group. In the warm acupuncture group, the warm acupuncture of Mongolian medicine was operated at Dinghuixue (at the center of the vertex, the crossing site of the anterior midline and the line connected the upper edges of two ear apexes), Heyixue (at the depression of the spinous process of the 7th cervical vertebra) or Xinxue (at the depression of the spinous process of the 6th thoracic vertebra) in each treatment.

Hypothermia has been widely used to treat moderate to severe neonatal hypoxic-ischemic encephalopathy (HIE), yet evaluating the effects of hypothermia relies on clinical neurology, neuroimaging, amplitude-integrated electroencephalography, and follow-up data on patient outcomes. Biomarkers of brain injury have been considered for estimating the effects of hypothermia. Proteins specific to the central nervous system (CNS) are components of nervous tissue, and once the CNS is damaged, these proteins are released into biofluids (cerebrospinal fluid, blood, urine, tears, saliva), and they can be used as markers of brain damage.

Background: Amniotic fluid contamination (AFC) is a risk factor for neonatal hypoxic ischemic encephalopathy (HIE); however, the correlation between AFC level and the incidence and clinical grading of HIE, in addition to relevant biomarkers of brain damage, have not been assessed.

Methods: This single-center observational study included 75 neonates with moderate-to-severe HIE. The neonates with HIE were divided into four subgroups according to the AFC level: normal amniotic fluid with HIE group (NAF-HIE), I°AFC with HIE group (I°AFC-HIE), II°AFC with HIE group (II°AFC-HIE), and III°AFC with HIE group (III°AFC-HIE).

Article Synopsis
  • * Researchers created bilayer nanoparticles using trimethyl chitosan and soy peptides to enhance the oral bioaccessibility of diosmin, achieving a nanoparticle size of about 250 nm with over 97% encapsulation efficiency.
  • * The nanoparticles protect diosmin during gastric digestion while improving its release in the intestine, and they demonstrate strong antioxidant activities, reducing harmful brain levels of Malondialdehyde (MDA) when taken orally.

Type 2 diabetes mellitus (T2DM) is a complex and heterogeneous disease that primarily results from impaired insulin secretion or insulin resistance (IR). G protein-coupled receptors (GPCRs) are proposed as therapeutic targets for T2DM. GPCRs transduce signals via the Gα protein, playing an integral role in insulin secretion and IR.

The observation of the Higgs boson solidified the standard model of particle physics. However, explanations of anomalies (for example, dark matter) rely on further symmetry breaking, calling for an undiscovered axial Higgs mode. The Higgs mode was also seen in magnetic, superconducting and charge density wave (CDW) systems.

Coffee cherry husks, the main byproduct of coffee production, contain an abundance of polyphenols. In this study, dextran sodium sulfate (DSS)-induced colitis mice were used to study the protective effects of polyphenolic extracts of coffee cherry husks (CCHP) on inflammation. The results indicated that CCHP administration alleviated the histological changes of DSS-induced colitis in mice and downregulated the mRNA level of TNF-α, IL-1β, IL-6 and Cox-2.

Vitexin is a flavonoid which exerted many protective activities. However, the low bioavailability discounts the in vivo effects of vitexin. This study designed vitexin loaded bilayer nanoparticles by the assembly of soybean peptides and the coating of goblet cell targeting peptide CSKSSDYQC (CSK) coupled N-trimethyl chitosan (TMC), to improve the bioavailability of vitexin.

3D anisotropic functional properties (such as magnetic, electrical, thermal, and optical properties, etc.) in a single material are not only beneficial to the multipurpose of a material, but also helpful to enrich the regulatory dimensionality of functional materials. Herein, a colossal 3D electrical anisotropy of layered MAB-phase MoAlB single crystal is introduced and dissected.

van der Waals (vdW) magnets have emerged as a tunable platform for exploring a variety of layer-dependent magnetic phenomena. Here we probe the thickness-dependent magnetism of vanadium triiodide (VI), a material known as a layered ferromagnetic Mott insulator in its bulk form, using magnetic circular dichroism microscopy. Robust ferromagnetism is observed in all thin layers, down to the monolayer limit with large coercive fields.

Vitexin, a millet-derived flavonoid, has been reported to have many biological activities. The present study investigated the function of vitexin in neural oxidative stress and neuro-inflammation through HO induced oxidative damage cell model and high-fat diet (HFD)-induced mice model. Both of in vitro and in vivo data indicated that vitexin could reduce the content of malondialdehyde (MDA), increase the activity and expression of antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), as well as down regulate the expression of inflammatory factors, such as TNF-α and IL-1β.

Objective: Multiple randomized controlled trials have shown that hypothermia is a safe and effective treatment for neonatal moderate or severe hypoxic-ischemic encephalopathy (HIE). The neuroprotective mechanisms of hypothermia need further study. The aim of this study was to investigate the effect of hypothermia on the serum levels of myelin basic protein (MBP) and tumor necrosis factor-α (TNF-α) as well as neurodevelopmental outcomes in neonatal HIE.

Using bilayer CrI_{3} as an example, we demonstrate that stacking domain walls in van der Waals magnets can host one-dimensional (1D) magnon channels, which have lower energies than bulk magnons. Interestingly, some magnon channels are hidden in magnetically homogeneous background and can only be inferred with the knowledge of stacking domain walls. Compared to 1D magnons confined in magnetic domain walls, 1D magnons in stacking domain walls are more stable against external perturbations.

It has recently been shown that quantum-confined states can appear in epitaxially grown van der Waals material heterobilayers without a rotational misalignment (θ = 0°), associated with flat bands in the Brillouin zone of the moiré pattern formed due to the lattice mismatch of the two layers. Peaks in the local density of states and confinement in a MoS/WSe system was qualitatively described only considering local stacking arrangements, which cause band edge energies to vary spatially. In this work, we report the presence of large in-plane strain variation across the moiré unit cell of a θ = 0° MoS/WSe heterobilayer and show that inclusion of strain variation and out-of-plane displacement in density functional theory calculations greatly improves their agreement with the experimental data.
