Abnormal dynamic features of cortical microstates for detecting early-stage Parkinson's disease by resting-state electroencephalography: Systematic analysis of the influence of eye condition.

Resting state electroencephalography (EEG) has proved useful in studying electrophysiological changes in neurodegenerative diseases. In many neuropathologies, microstate analysis of the eyes-closed (EC) scalp EEG is a robust and highly reproducible technique for assessing topological changes with high temporal resolution. However, scalp EEG microstate maps tend to underestimate the non-occipital or non-alpha-band networks, which can also be used to detect neuropathological changes.

Diabetes mortality burden attributable to influenza in China: A population-based time-series analysis.

Background: Previous studies have found an association between influenza, cardiovascular and cerebrovascular disease mortality, and all-cause mortality. And the vaccination of elderly diabetes is often recommended to reduce the risk of hospitalization and death. Nevertheless, no previous work has investigated the short-term impact of influenza on diabetes mortality in China.

Anti-Osteoporosis Is Imperative in Prevention of Progress of Ankylosing Spondylitis.

Background: Ankylosing spondylitis (AS) is a chronic autoimmune disease that affects the spine and peripheral joints, often leading to kyphosis, joint stiffness, and even ankylosis. Sagittal parameters, such as total thoracic kyphosis (TTK), thoracic kyphosis (TK), major thoracic kyphosis (MTK), and thoracolumbar kyphosis (TLK), are crucial indices for evaluating spinal alignment in AS patients and can reflect disease progression. This study aims to explore the relationship between bone mineral density (BMD), sagittal parameters, and joint ankylosis in AS patients.

Therapeutic effect of low-dose BMSCs-Loaded 3D microscaffold on early osteonecrosis of the femoral head.

The early treatment of Osteonecrosis of Femoral Head (ONFH) remains a clinical challenge. Conventional Bone Marrow Mesenchymal Stem Cell (BMSC) injection methods often result in unsatisfactory outcomes due to mechanical cell damage, low cell survival and retention rates, inadequate cell matrix accumulation, and poor intercellular interaction. In this study, we employed a novel cell carrier material termed "3D Microscaffold" to deliver BMSCs, addressing these issues and enhancing the therapeutic effects of cell therapy for ONFH.

Revolutionizing Tissue Clearing and 3-Dimensional Imaging: Transparent Embedding Solvent System for Uniform High-Resolution Imaging.

Combining transparent embedding with sectioning is likely to be the future direction for tissue clearing and 3-dimensional (3D) imaging. A newly published transparent embedding system, TESOS (Transparent Embedding Solvent System), ensures consistent submicron resolution imaging throughout the entire sample, and can be compatible with different microscopy systems. This method shows great potential in connectome mapping, and might be an optimal option for future 3D multiplex immunofluorescence and RNA in situ hybridization imaging.

Fundamentals of intervertebral disc degeneration and related discogenic pain.

Lumbar intervertebral disc degeneration is thought to be the main cause of low back pain, although the mechanisms by which it occurs and leads to pain remain unclear. In healthy adult discs, vessels and nerves are present only in the outer layer of the annulus fibrosus and in the bony endplate. Animal models, and histological and biomechanical studies have shown that annulus tear or endplate injury is the initiating factor for painful disc degeneration.

Role of neurogenic inflammation in intervertebral disc degeneration.

In healthy intervertebral discs (IVDs), nerves and blood vessels are present only in the outer annulus fibrosus, while in degenerative IVDs, a large amount of nerve and blood vessel tissue grows inward. Evidence supports that neurogenic inflammation produced by neuropeptides such as substance P and calcitonin gene related peptide released by the nociceptive nerve fibers innervating the IVDs plays a crucial role in the process of IVD degeneration. Recently, non-neuronal cells, including IVD cells and infiltrating immune cells, have emerged as important players in neurogenic inflammation.

Bolstered bone regeneration by multiscale customized magnesium scaffolds with hierarchical structures and tempered degradation.

Addressing irregular bone defects is a formidable clinical challenge, as traditional scaffolds frequently fail to meet the complex requirements of bone regeneration, resulting in suboptimal healing. This study introduces a novel 3D-printed magnesium scaffold with hierarchical structure (macro-, meso-, and nano-scales) and tempered degradation (microscale), intricately customized at multiple scales to bolster bone regeneration according to patient-specific needs. For the hierarchical structure, at the macroscale, it can feature anatomic geometries for seamless integration with the bone defect; The mesoscale pores are devised with optimized curvature and size, providing an adequate mechanical response as well as promoting cellular proliferation and vascularization, essential for natural bone mimicry; The nanoscale textured surface is enriched with a layered double hydroxide membrane, augmenting bioactivity and osteointegration.

Hydrogen bonding-mediated phase-transition gelatin-based bioadhesives to regulate immune microenvironment for diabetic wound healing.

Gelatin-based biomaterials have emerged as promising candidates for bioadhesives due to their biodegradability and biocompatibility. However, they often face limitations due to the uncontrollable phase transition of gelatin, which is dominated by hydrogen bonds between peptide chains. Here, we developed controllable phase transition gelatin-based (CPTG) bioadhesives by regulating the dynamic balance of hydrogen bonds between the peptide chains using 2-hydroxyethylurea (HU) and punicalagin (PA).

bFGF-Chitosan "brain glue" promotes functional recovery after cortical ischemic stroke.

The mammalian brain has an extremely limited ability to regenerate lost neurons and to recover function following ischemic stroke. A biomaterial strategy of slowly-releasing various regeneration-promoting factors to activate endogenous neurogenesis represents a safe and practical neuronal replacement therapy. In this study, basic fibroblast growth factor (bFGF)-Chitosan gel is injected into the stroke cavity.

Effects of unsaturated C18 fatty acids on "glucose-glutathione" Maillard reaction: Comparison and formation pathways of initial stage and meaty flavor compounds.

To explore the effect of oleic acid, linoleic acid, and linolenic acid on "glucose-glutathione" Maillard reaction initial stage and meaty flavor compounds formation pathways, glutathione-Amadori compound was synthesized, and identified by Q/TOF and NMR. Depending on the concentration of glutathione and glutathione-Amadori compound quantified by UPLC-MS/MS, the unsaturated C18 fat acids inhibited glutathione Amadori compound formation or accelerated degradation, and oleic acid inhibited most markedly. The results showed that 65 volatile compounds were detected by GC-MS-O in four model systems.

No microorganism was detected in amniotic fluid of healthy pregnancies from the second trimester to the delivery.

Background: The early colonization and establishment of the microbiome in newborns is a crucial step in the development of the immune system and host metabolism. However, the exact timing of initial microbial colonization remains a subject of ongoing debate. While numerous studies have attempted to determine the presence or absence of intrauterine bacteria, the majority of them have drawn conclusions based on sequencing data from maternal or infant samples taken at a single time point.

TERT de novo mutation-associated dyskeratosis congenita and porto-sinusoidal vascular disease: a case report.

Background: Dyskeratosis congenita is a rare genetic disease due to telomere biology disorder and characterized by heterogeneous clinical manifestations and severe complications. "Porto-sinusoidal vascular disease" has been recently proposed, according to new diagnostic criteria, to replace the term "idiopathic non-cirrhotic portal hypertension." TERT plays an important role in telomeric DNA repair and replication.

The causal relationship between steroid hormones and risk of stroke: evidence from a two-sample Mendelian randomization study.

It is unclear how steroid hormones contribute to stroke, and conducting randomized controlled trials to obtain related evidence is challenging.
