This study aimed to evaluate the relationships between hematological inflammatory indicators and the enhancement of ICAS plaques and to search for hematological indicators that can predict ICAS plaque instability.
Methods: Consecutive adult patients diagnosed with ICAS from April 2018 to December 2021 were recruited retrospectively, and every patient underwent HR-VWI.
Objective: Polypyrimidine tract-binding protein 1 (PTBP1) is an RNA-binding protein, which plays a role in pre-mRNA splicing and in the regulation of alternative splicing events. However, little was known about the correlation between PTBP1 and glioma and its prognostic significance in glioma patients. Our aim was to investigate the expression, functional role, and prognostic value of PTBP1 in glioma.

Context: Osteoarthritis (OA) is a common chronic degenerative joint disease resulting in physical disability and reduced quality of life. Different biochemical signaling pathways are involved in the progression of OA, including the c-Jun NH2-terminal kinase (JNK) signal transduction pathway.
Objective: In this study, we have reviewed the recent updates on the association of JNK pathway with OA.
Osteoarthritis (OA) is characterized by progressive destruction of articular cartilage, resulting in significant disability. Chondrocytes present in various types of cartilage and are responsible for the growth and maintenance of the tissue. Over-proliferation of human chondrocytes may contributes to OA pathological process.

This study investigated the effects of arm swing under natural arm swing condition and active arm swing condition on local dynamic stability and gait variability of the trunk segments (C7 and T10 joint) and lower extremity joints (hip, knee and ankle joint). The local divergence exponents (λs) and mean standard deviation over strides (MeanSD) of 24 young healthy adults were calculated while they were walking on treadmill with two arm swing conditions at their preferred walking speed (PWS).

Earlier studies have shown that osthole, a main active constituent isolated from Cnidium monnieri (L.) Cusson, could be considered as an attractive therapeutic agent in the treatment of ischemic stroke.
View Article and Find Full Text PDFAims: Oxidative stress (OS) plays an important role in the pathogenesis of neurodegenerative diseases, including Alzheimer's disease (AD). This study was designed to uncover the cellular and biochemical mechanisms underlying the neuroprotective effects of tacrine-3-caffeic acid (T3CA), a novel promising multifunctional anti-Alzheimer's dimer, against OS-induced neuronal death.
Methods And Results: T3CA protected HT22 cells against high-concentration-glutamate-induced cell death in time- and concentration-dependent manners and potently attenuated glutamate-induced intracellular reactive oxygen species (ROS) production as well as mitochondrial membrane-potential (ΔΨ) disruption.

An analytic model for an injection-locked dual-loop optoelectronic oscillator (OEO) is proposed and verified by experiments in this paper. Based on this theoretical model, the effect of injection power on the single-sideband phase noise of the OEO is analyzed, and results suggest that moderate injection is one key factor for a balance between phase noise and spur for OEO. In order to measure superlow phase noise of OEOs, a cross-correlation measurement system based on the fiber delay line is built, in which high linear photodetector and low-phase-noise amplifier are used to improve systematic sensitivity.

With the comparison of the historical data in 1960, the potential effects of intensive aquaculture on the aquatic environment were analyzed, aimed to provide theoretical support for the sustainable fishery of freshwater lakes. A total of 98 phytoplankton species belonging to 7 phyla and 54 genera were collected, among which, Peridinium bipes, Chroomonas acuta, Chlorella vulgaris, Crytomonas ovate, Cyclotella meneghiniana, Crytomonas erosa, Anabaena circinalis, Microcystis aeruginosa, and Anabaena azotica were the dominant species, and had obvious seasonal variations.

Objective: There is currently no consensus on a standardized treatment strategy for olfactory neuroblastoma (ONB), especially for intracranial invasion. This purpose of this study is to explore the appropriate treatment modality and prognostic factors of intracranial invasive ONB.
Study Design: Case series with chart review.
Background: Spontaneous intracerebral hemorrhage (ICH) carries a high mortality rate, with survivors commonly left with permanent neurological deficits. Mesenchymal stem cell (MSC) transplantation promotes functional recovery in experimental ICH, and treatment with hepatocyte growth factor (HGF) is beneficial in ischemic stroke.
Objective: We hypothesize that transplantation of MSCs with previous transduction of HGF has an additive effect in promoting neurological recovery through myelin and axonal regeneration.
Objectives: This study aimed to investigate the possible modification of the neuroprotective effect of sodium ferulate, when orally co-administered with borneol, in transient global cerebral ischaemia-induced functional, histological and cellular alterations in mice.
Methods: The bilateral common carotid artery occlusion was conducted in C57 BL/6J mice for 25 min. The mice were then subjected to a water maze test over an extended recovery period, followed by an assessment of neuronal loss in the CA1 region of the hippocampus (haematoxylin and eosin staining).
