The Basic Theory and Application of the Mirror Neuron System in Dysphagia after Stroke.

The discovery of the brain's mirror neuron system enables researchers to gain a deeper understanding of social cognitive activities from the level of neural mechanisms. Mirror neurons are situated in bilateral brain regions, overlapping with the swallowing neural network, and there are complex network pathways connecting the two. Repeatedly inducing the activation of mirror neurons in stroke patients can enhance the brain's ability to relearn its original swallowing function, and then restore the swallowing neural network.

Expression and prognostic value of ferritinophagy-related NCOA4 gene in low-grade glioma: integration of bioinformatics and experimental validation.

Background: Low-grade glioma (LGG) is a primary brain tumor with relatively low malignancy. NCOA4 is a key regulator of ferritinophagy-related processes and is involved in the occurrence and development of many cancers. However, the role of NCOA4 in LGG remains poorly understood.

Supramolecular phosphorescent assemblies based on cucurbit[8]uril and bromophenylpyridine derivatives for dazomet recognition.

A bromophenylpyridine derivative (N1) was designed, synthesized, and the molecule was incorporated into the cavity of the cucurbit[8]uril (Q[8]) as a guest to form a 2:1 host-guest complex. This complex demonstrates good room temperature phosphorescence (RTP) properties in aqueous solution. The host-guest interaction and optical properties of N1@Q[8] in aqueous solution were studied by means of H NMR, ultraviolet-visible absorption spectroscopy, fluorescence spectroscopy, phosphorescence spectroscopy, scanning electron microscopy and inverted fluorescence microscopy.

Intermittent oro-esophageal tube feeding for cerebral small vessel disease patients with dysphagia: A randomized controlled study.

Methods: This randomized controlled study included 60 CSVD patients with dysphagia who received routine treatment. Participants were randomly divided into the intervention group (with IOE, n = 30) and the control group (with NGT, n = 30).

Chromosomal rearrangements and instability caused by the LINE-1 retrotransposon.

LINE-1 (L1) retrotransposition is widespread in many cancers, especially those with a high burden of chromosomal rearrangements. However, whether and to what degree L1 activity directly impacts genome integrity is unclear. Here, we apply whole-genome sequencing to experimental models of L1 expression to comprehensively define the spectrum of genomic changes caused by L1.

Sulforaphane inhibits multiple myeloma cell-induced osteoclast differentiation and macrophage proliferation by elevating ferroportin1.

Purpose: Osteolysis is a common complication in patients with multiple myeloma (MM). Our previous studies have demonstrated that MM cells can promote osteoclast differentiation of macrophages. In this study, we explored the effect of sulforaphane (SFN), a natural NRF2 activator found in broccoli, on MM cell-induced osteoclast differentiation.

Knockdown of TcGluCl leads to the premature pupation of Tribolium castaneum larvae possibly by influencing the calcium-mediating hormone homeostasis.

The glutamate-gated chloride channels (GluCls) are widely existed in the neural and nonneural tissues of invertebrate. In addition to play important roles in signal transduction, the GluCls also showed multiple physiological functions in insects such as participate in the juvenile hormone synthesis. In the present study, the potential roles of TcGluCl in growth and development of the red flour beetle Tribolium castaneum were explored.

Opposite expression of NCOA4 in glioblastoma tissues and cell lines.

Recent research has found that ferroptosis is the most prevalent type of programmed cell death in glioma tissues and is associated with malignant progression, poor prognosis, and exacerbated immune suppression in glioblastoma (GBM). In recent years, nuclear receptor coactivator 4 (NCOA4) has been identified as a key protein in ferroptosis, but its expression in GBM tissues remains unclear. We observed an intriguing phenomenon where the expression pattern of NCOA4 was opposite in GBM tissues compared to three GBM cell lines (U87-MG, U251, and LN229), with NCOA4 expression being elevated in brain tissue but decreased in the GBM cells.

How enteral nutrition modes influence nasopharyngeal carcinoma survivors with late dysphagia after radiotherapy: a randomized controlled study.

Background: Palliation to late dysphagia after radiotherapy for nasopharyngeal carcinoma (NPC) continues to be a challenge. Intermittent oro-esophageal tube feeding (IOE) is an emerging enteral nutrition mode that can address nutrition and quality of life issues related to nasogastric tube feeding (NGT).

Objectives: This study aims to investigate the effect of IOE versus NGT in late dysphagia after radiotherapy for NPC.

The molecular mechanisms of chemotherapeutic resistance in tumors (Review).

Chemotherapy remains a prevalent treatment for a wide range of tumors; however, the majority of patients undergoing conventional chemotherapy experience varying levels of chemoresistance, ultimately leading to suboptimal outcomes. The present article provided an in‑depth review of chemotherapy resistance in tumors, emphasizing the underlying factors contributing to this resistance in tumor cells. It also explored recent advancements in the identification of key molecules and molecular mechanisms within the primary chemoresistant pathways.

Application of Matrix-Assisted Laser Desorption Ionization Time-of-Flight Mass Spectrometry for Identification of Foodborne Pathogens: Current Developments and Future Trends.

Foodborne pathogens have gained sustained public attention, exerted significant pressure on food manufacturers, and posed serious health risks to human. Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) has been employed for quick and accurate identification of microorganisms in the prevention of foodborne epidemics in recent years. Herein, we first summarize the principle of MALDI and its workflow for foodborne pathogens.

PHF8/KDM7B: A Versatile Histone Demethylase and Epigenetic Modifier in Nervous System Disease and Cancers.

Many human diseases, such as malignant tumors and neurological diseases, have a complex pathophysiological etiology, often accompanied by aberrant epigenetic changes including various histone modifications. Plant homologous domain finger protein 8 (PHF8), also known as lysine-specific demethylase 7B (KDM7B), is a critical histone lysine demethylase (KDM) playing an important role in epigenetic modification. Characterized by the zinc finger plant homology domain (PHD) and the Jumonji C (JmjC) domain, PHF8 preferentially binds to H3K4me3 and erases repressive methyl marks, including H3K9me1/2, H3K27me1, and H4K20me1.

Assessment of lower respiratory tract microbiota associated with pulmonary tuberculosis in children.

Background: The respiratory microbiota plays a crucial role in the development of tuberculosis (TB).
