Changes in short-chain fatty acids affect brain development in mice with early life antibiotic-induced dysbacteriosis.

Background: Early enteral nutrition and the gut microbiota profoundly influence neonatal brain development, with short-chain fatty acids (SCFAs) from the microbiota playing a pivotal role. Understanding the relationship between dysbiosis, SCFAs, and brain development is crucial. In this study, we investigated the impact of antibiotics on the concentration of SCFAs in neonatal feces.

Effects of intra- and inter-day temperature change on acute upper respiratory infections among college students, assessments of three temperature change indicators.

Background: Acute upper respiratory infection (AURI) is a significant disease affecting all age groups worldwide. The differences in the impacts of different temperature change indicators, such as diurnal temperature range (DTR), temperature variation (TV), and temperature change between neighboring days (TCN), on AURI morbidity, are not clear.

Methods: We collected data on 87,186 AURI patients during 2014-2019 in Zhengzhou.

Expanding the Potential of Neoantigen Vaccines: Harnessing Bacille Calmette-Guérin Cell-Wall-Based Nanoscale Adjuvants for Enhanced Cancer Immunotherapy.

Personalized antitumor immunotherapy utilizing neoantigen vaccines holds great promise. However, the limited immunogenicity of existing recognized neoantigens and the inadequate stimulation of antitumor immune responses by conventional adjuvants pose significant challenges. To address these limitations, we developed a nanovaccine that combines a BCG bacterial cell wall skeleton (BCG-CWS) based nanoscale adjuvant (BCNA) with peptide neoantigens (M27 and M30).

Study on the role of CCM3 gene and lead exposure induced neurotoxicity through neurovascular units.

Single-Mode Control and Individual Nanoparticle Detection in the Ultraviolet Region Based on Boron Nitride Microdisk with Whispering Gallery Mode.

Optical microcavities are known for their strongly enhanced light-matter interactions. Whispering gallery mode (WGM) microresonators have important applications in nonlinear optics, single-mode output, and biosensing. However, there are few studies on resonance modes in the ultraviolet spectrum because most materials with high absorption properties are in the ultraviolet band.

Genomic insights and antimicrobial resistance profiles of CRKP and non-CRKP isolates in a Beijing geriatric medical center: emphasizing the carrying high-risk clones and their spread.

Background: The escalating resistance of , a prevalent pathogen in healthcare settings, especially its carbapenem-resistant (CRKP), to a wide array of antibiotics, notably β-lactams, constitutes a formidable challenge for healthcare and global public health management.

Methods: This research compared the resistance phenotypes and genomic profiles of CRKP and Non-CRKP isolates in a Beijing hospital, focusing on high-risk gene-bearing CRKP clones and the structure of mobile genetic elements facilitating their spread across hospital departments. Forty isolates were collected from various departments of the hospital and subjected to antimicrobial susceptibility testing and whole-genome sequencing to analyze their resistance phenotypes and genomic features.

Drug-Loaded Bacillus Calmette-Guérin Bacteria for Immuno-Chemo Combo Therapy in Bladder Cancer.

Intravesical Bacillus Calmette-Guérin (BCG) is a well-established strategy for managing high-risk nonmuscle-invasive bladder cancer (NMIBC); however, over half of patients still experience disease recurrence or progression. Although the combined intravesical instillation of various chemotherapeutic drugs is implemented in clinical trials to enhance the BCG therapy, the outcome is far from satisfying due to severe irritative effects and treatment intolerance at high doses. Therefore, it is adopted the "biotin-streptavidin strategy" to doxorubicin (DOX)-encapsulated nanoparticles within live BCG bacteria (DOX@BCG) to improve treatment outcomes.

Outdoor environmental exposome and the burden of tuberculosis: Findings from nearly two million adults in northwestern China.

We simultaneously assessed the associations for a range of outdoor environmental exposures with prevalent tuberculosis (TB) cases in a population-based health program with 1940,622 participants ≥ 15 years of age. TB status was confirmed through bacteriological and clinical assessment. We measured 14 outdoor environmental exposures at residential addresses.

Identification of tree species based on the fusion of UAV hyperspectral image and LiDAR data in a coniferous and broad-leaved mixed forest in Northeast China.

Rapid and accurate identification of tree species remote sensing technology has become one of the important means for forest inventory. This paper is to develop an accurate tree species identification framework that integrates unmanned airborne vehicle (UAV)-based hyperspectral image and light detection and ranging (LiDAR) data under the complex condition of natural coniferous and broad-leaved mixed forests. First, the UAV-based hyperspectral image and LiDAR data were obtained from a natural coniferous and broad-leaved mixed forest in the Maoer Mountain area of Northeast China.

Whole transcriptome sequencing reveals a TCF4-ZNF384 fusion in acute lymphoblastic leukemia.

Previous studies have shown that, the clinical features and prognosis of ZNF384-rearranged pediatric acute lymphoblastic leukemia (ALL) depend on its translocation partners. We report two cases of TCF4-ZNF384 fusion, one 6-year-old girl and one 10-year-old boy, both diagnosed by whole-transcriptome sequencing, and TCF4 is the newest fusion partner of ZNF384. As illustrated in this first report of TCF4-ZNF384 fusion in ALL patients, the identification of patients with ZNF384 rearrangement in ALL patients is critical to elucidate outcomes associated with a specific rearrangement and to develop appropriate treatment strategies.
