Advanced glycation end products (AGEs) generated from the Maillard reaction (MR) during food processing in the human physiological environment, have been proven to be significantly associated with various chronic metabolic diseases. In this study, 18 flavonoids were investigated to study their effects on AGEs formation during MR within a glucose-lysine-arginine model system. Five AGEs- N-carboxymethyl-lysine (CML), N-carboxyethyl-lysine (CEL), pyrraline, pentosidine, and argpyrimidine-were determined by high-performance liquid chromatography-mass spectrometry, with inhibitory rates ranging between 0 % and 71.

Metagenomic next-generation sequencing (mNGS) has greatly improved our understanding of pathogens in infectious diseases such as pulmonary tuberculosis (PTB). However, high human DNA background (> 95%) impedes the detection sensitivity of mNGS in identifying intracellular Mycobacterium tuberculosis (MTB), posing a pressing challenge for MTB diagnosis. Therefore, there is an urgent need to improve MTB diagnosis performance in PTB patients.

Effective fractionation of lignocellulose into hemicellulose, cellulose, and lignin is the precondition for full-component valorization. Generally, harsh reaction conditions are used to improve fractionation efficiency, which leads to severe lignin condensation and inhibits its value-added applications. To address this issue, a novel biphasic system consisting of molten salt hydrates (MSHs) and n-butanol was developed for birch fractionation.

Natural polysaccharides attract scientists and industries' interest with diverse applications in biomaterials, immune regulation, gut microbiota regulation, food additives, and more. Nevertheless, the absence of standardized purity criteria created significant challenges in characterizing polysaccharides, leading to varied and complicated structures, and impeding progress in research and development. Consequently, it is essential to obtain samples that adhere to high-level and unified purity standards for effective polysaccharide research.

Background: Constipation is one of the most common non-motor symptoms in patients with Parkinson's disease (PD), which could manifest during the early stage of the disease. However, the etiology of constipation in PD remains largely unknown. Previous studies supported that gastrointestinal dysfunction may be associated with functional connectivity alterations in paraventricular hypothalamic nucleus (PVN).

Background: Lateral cervical lymph node metastasis (LLNM) is a well-established prognostic factor influencing recurrence and survival in patients with papillary thyroid carcinoma (PTC). However, the accuracy of preoperative imaging examinations is limited. We have pioneered a minimally invasive technique-endoscopic thyroidectomy via sternocleidomastoid muscle posteroinferior approach (ETSPIA).

Background And Purpose: Patients with obstructive sleep apnea (OSA) experience chronic intermittent hypoxia and sleep fragmentation, leading to brain ischemia and neurological dysfunction. Therefore, it is important to identify features that can differentiate patients with OSA from healthy controls (HC) and provide insights into the underlying brain alterations associated with OSA. This study aimed to distinguish patients with OSA from healthy individuals and predict clinical symptom alterations using cerebellum-whole-brain static and dynamic functional connectivity (sFC and dFC, respectively), with the cerebellum as the seed region.

Purpose: A transoral surgical corridor can provide adequate exposure for extirpation of benign tumors arising from the parapharyngeal space (PPS). However, peri-operative complications following a transoral approach to the PPS have not been sufficiently described. This study retrospectively reviewed patients with PPS tumor extirpated via an endoscopic-assisted transoral approach, aiming to evaluate the safety of this approach and summarize the peri-operative complications.

Purpose: This study is to evaluate the altered number of functional connection (s) in patients with obstructive sleep apnea (OSA) by functional connectivity density (FCD), to investigate its relationship with cognitive function, and to explore whether these features could be used to distinguish OSA from healthy controls (HCs).

Methods: Seventy-six OSA patients and 72 HCs were included in the analysis. All participants underwent resting-state functional magnetic resonance imaging scan.

The impact of volatile organic compounds (VOCs) on type 2 diabetes (T2D) among older adults is unknown. The multiple linear regression model and the multiple binary logistic regression were used to evaluate the relationships between mVOCs and glucose homeostasis/T2D, respectively. Among the 19 mVOCs, the higher levels of urinary N-acetyl-S-(2-hydroxypropyl)-L-cysteine (2HPMA, compound CID:44146439) and N-acetyl-S-(2-hydroxypropyl)-L-cysteine (HPMMA, compound CID:107774684) were significantly associated with higher odds of T2D (OR = 1.

Background: Previous studies have reported that the tumor immune microenvironment (TIME) was associated with the prognosis of lung cancer patients and the efficacy of immunotherapy. However, given the significant challenges in obtaining specimens of brain metastases (BrMs), few studies explored the correlation between the TIME and the prognosis in patients with BrMs from lung adenocarcinoma (LUAD).

Methods: Transcript profiling of archival formalin-fixed and paraffin-embedded specimens of BrMs from 70 LUAD patients with surgically resected BrMs was carried out using RNA sequencing.

Fructose 1,6-diphosphatase 1 (FBP1) is an enzyme involved in gluconeogenesis and glycolysis inhibition. Dendritic cells (DCs) are antigen-presenting cells, and antigens presented to T cells activate the immune response. FBP1 inhibits the development of several tumors, and high FBP1 expression inhibits the proliferation, migration, and invasion of lung cancer cells.
