Background: Recent research has revealed a significant association between Anillin (ANLN) and miR-374a‑5p with the progression of tumors. Additionally, bioinformatics analysis indicated an inverse relationship in transcript expression levels between ANLN and miR-374a-5p. However, the specific mechanisms driving the miR-374a-5p/ANLN signaling axis in oral squamous cell carcinoma (OSCC) have not been thoroughly explored.

Article Synopsis
  • Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) have high mortality rates with limited treatment options, prompting research into human placental mesenchymal stem cells (hPMSCs) as a potential remedy.
  • The study involved inducing ALI in mice using lipopolysaccharide (LPS) and administering hPMSCs, showing improved lung health and reduced inflammation through changes in key inflammatory markers.
  • Findings indicated that the presence of the ACE2 gene is vital for the therapeutic effects of hPMSCs, suggesting a significant role in repairing lung tissue and providing a basis for future clinical treatments for ALI.

Article Synopsis
  • - The study investigates how nitric oxide (NO) enhances polysaccharide production in Nostoc flagelliforme through a process called S-nitrosylation (SNO), which modifies certain enzymes involved in this biosynthesis.
  • - It was found that certain key enzymes (G6PDH, ICDH, and UGDH) have their activity correlated with NO levels, and specific enzymes (UGDH and G6PDH) are particularly affected by SNO, as shown through various laboratory techniques.
  • - The research identifies specific sites on the enzymes that are modified by NO and proposes that this mechanism could lead to improved industrial production of polysaccharides from Nostoc flagelliforme.

Objective: Depression is a common comorbidity in hypertensive older adults, yet depression is more difficult to diagnose correctly. Our goal is to find predictive models of depression in hypertensive patients using a combination of various machine learning (ML) methods and metabolomics.

Methods: Methods We recruited 379 elderly people aged ≥65 years from the Chinese community.

Background: Untargeted metabonomics has provided new insight into the pathogenesis of sarcopenia. In this study, we explored plasma metabolic signatures linked to a heightened risk of sarcopenia in a cohort study by LC-MS-based untargeted metabonomics.

Methods: In this nested case-control study from the Adult Physical Fitness and Health Cohort Study (APFHCS), we collected blood plasma samples from 30 new-onset sarcopenia subjects (mean age 73.

Background: Stroke survivors often face challenges in motor learning and motivation during rehabilitation, which can impede their recovery progress. Traditional rehabilitation methods vary in effectiveness, prompting the exploration of novel approaches such as reward strategies. Previous research indicates that rewards can enhance rehabilitation motivation and facilitate motor learning.

Depression is a serious psychiatric illness that causes great inconvenience to the lives of elderly individuals. However, the diagnosis of depression is somewhat subjective. Nontargeted gas chromatography (GC)/liquid chromatography (LC)-mass spectrometry (MS) was used to study the plasma metabolic profile and identify objective markers for depression and metabolic pathway variation.

Background: Untargeted metabolomics can be used to expand our understanding of the pathogenesis of sarcopenia. However, the metabolic signatures of sarcopenia patients have not been thoroughly investigated. Herein, we explored metabolites associated with sarcopenia by untargeted gas chromatography (GC)/liquid chromatography (LC)-mass spectrometry (MS) and identified possible diagnostic markers.

Purpose: For early diagnosis of osteoporosis (OP), plasma metabolomics of OP was studied by untargeted LC/GC-MS in a Chinese elderly population to find possible diagnostic biomarkers.

Methods: A total of 379 Chinese community-dwelling older adults aged ≥65 years were recruited for this study. The BMD of the calcaneus was measured using quantitative ultrasound (QUS), and a T value ≤-2.

Introduction: There is a growing body of recent literature linking the association of specific or multiple lifestyles with cognitive impairment, but most of these studies have been conducted in Western populations, and it is necessary to study multiple lifestyles and cognitive abilities in different populations, with the primary population of this study being a select group of community-dwelling older adults in Shanghai, China.

Methods: The sample included 2,390 community-dwelling Chinese participants. Their cognitive function was assessed using the Mini-Mental State Examination (MMSE).

Background: The neutrophil-to-lymphocyte ratio (NLR) is a marker of inflammation that can be obtained quickly, conveniently, and cheaply from blood samples. However, there is no research to explore the effects of sex and age on the relationship between the NLR and mild cognitive impairment (MCI) in community-dwelling older adults.

Methods: A total of 3,126 individuals aged over 60 years in Shanghai were recruited for face-to-face interviews, and blood samples were collected.

Article Synopsis
  • Researchers successfully created one-dimensional nanofibers of ZnGaO, ZnO, and a combination of both using electrostatic spinning to study their effectiveness in breaking down tetracycline hydrochloride (TC-HCl).* -
  • The ZnGaO/ZnO composite formed a S-scheme heterojunction, which helped reduce the recombination of photogenerated carriers, leading to improved photocatalytic performance.* -
  • By adjusting the ratio of ZnGaO to ZnO, they achieved a maximum degradation rate of 0.0573 min, which is 20 times greater than TC-HCl's natural degradation rate, demonstrating a new method for efficient photocatalytic degradation.*
