This study examines the distribution of microbial communities and antibiotic resistance genes (ARGs) across various vectors in poultry farm environments. The results show that airborne particulate matter (PM) and soil harbor the highest counts of microbial genes, exceeding those found in poultry visceral samples, which display lower microbial diversity and ARG levels. This highlights environmental vectors, particularly soil and PM, as major reservoirs for ARGs.

Eosinophilic gastroenteritis (EGE) is an inflammatory disease characterized by a significant increase in eosinophils. EGE itself is rare, and cases with clinical manifestations of hemorrhagic ascites are even rarer, which undoubtedly increases the risk of misdiagnosis. Given this, this study reports a rare case of pediatric EGE presenting with paroxysmal abdominal pain without apparent cause, accompanied by acute tonsillitis and mesenteric lymphadenitis, suggesting a possible intestinal infection.

Article Synopsis
  • This study looks at how traumatic stress affects gene expression in specific areas of the brain (the mPFC) linked to neuropsychiatric disorders like PTSD and anxiety disorders.* -
  • Using an animal model of stress, researchers found 62 genes that were expressed differently in the brain areas studied, with each area showing unique patterns related to functions like synapse formation and neuronal activity.* -
  • The findings suggest that certain pathways related to neurodegeneration and stress signaling may play a role in how individuals respond to trauma, highlighting potential areas for further research and treatment.*

Purpose: We aimed to evaluate the clinical efficacy of a combined treatment regimen involving terpinen-4-ol (T4O) and eyelid deep cleaning for managing Demodex blepharitis.

Methods: In this randomized, open-label trial, 40 patients diagnosed with Demodex blepharitis at the Cornea Specialty Clinic of Hankou Aier Eye Hospital were enrolled. Participants were randomly assigned to either a T4O or a combination treatment group.

Article Synopsis
  • - The standard treatment for small-cell lung cancer (SCLC) is platinum-based chemotherapy, which has a high response rate of 50-90%.
  • - Durvalumab, an immune checkpoint inhibitor, is now recommended as a first-line treatment alongside traditional chemotherapy for advanced SCLC, although it can lead to immune-related side effects.
  • - This case report highlights a man in his late 50s with extensive-stage SCLC who developed rare and potentially fatal autoimmune encephalitis after receiving durvalumab treatment, contributing to the understanding of this adverse effect.

Background: The relationship between dysregulation of the immune system and reproductive health, particularly in the context of abortion, is an area of critical research. Identifying the immunological factors that contribute to abortion could provide valuable insights into its prevention and management.

Methods: This study used bidirectional two-sample Mendelian Randomization (MR) approach to evaluate the causal link between 731 immune cell features and the risk of abortion.

  • The study aims to create a nomogram for early prediction of severe mycoplasma pneumoniae pneumonia (SMPP) in both pediatric and adult patients by analyzing 550 cases, classified into severe and non-severe groups.
  • Various models were developed using clinical data, imaging, and radiomics features, assessed through different statistical methods, including logistic regression and AUC metrics.
  • The integrated model showed strong predictive ability, particularly in testing cohorts, with a notable improvement when combining clinical and imaging features, demonstrating its effectiveness for identifying SMPP.

Purpose: This study aimed to identify preoperative factors that predict visual acuity and Kmax 3 years after corneal cross-linking (CXL) in patients with keratoconus (KC), and to develop a prediction model.

Methods: We enrolled 68 patients with KC and followed up on 100 eyes that received CXL for at least 3 years. Preoperative data, including age, UDVA, CDVA, cylinder, SE, and the parameters of tomography including Kmax were collected as predictors.

Background: Intracerebral hemorrhage (ICH) stands out as the most fatal subtype of stroke, currently devoid of effective therapy. Recent research underscores the significance of Axl and its ligand growth arrest-specific 6 (Gas6) in normal brain function and a spectrum of neurological disorders, including ICH. This study is designed to delve into the role of Gas6/Axl signaling in facilitating hematoma clearance and neuroinflammation resolution following ICH.

Chemosensory protein (CSP) genes significantly enriched in the female antennae are potential molecular candidates for mediating female oviposition behaviors. In this study, we presented the interaction mechanisms of a female-antenna-biased PxutCSP19 in to 47 host volatiles, four biopesticides and 24 synthetic insecticides. Using a bioinformatics-based homology search, 22 genes orthologous to PxutCSP19 were identified from 22 other butterflies with high sequence identities to each other (73.

Photothermal therapy synergized with photodynamic therapy for the treatment of tumors has emerged as a promising strategy. However, designing photosensitizers with both high photothermal efficiency and high photodynamic performance remains challenging. In contrast, the strategy of rationalizing the design of photosensitizers using the physiological properties of tumors to improve the photon utilization of photosensitizers during phototherapy is more advantageous than the approach of endowing a single photosensitizer with complex functions.

Background: Driver genes are essential predictors of targeted therapeutic efficacy. Detecting driver gene mutations in lung adenocarcinoma (LUAD) patients can help to screen for targeted drugs and improve patient survival benefits. This study aims to investigate the mutation characterization of driver genes and their correlation with clinicopathological features in LUAD.

A novel dispersive solid-phase microextraction method based on a metal-organic framework (MIL-100(Fe)) combined with a dispersive liquid-liquid microextraction technique was proposed for the extraction and enrichment of four insecticides in beverages. The qualitative and quantitative analysis of these insecticides was conducted using HPLC-MS/MS. To optimize the extraction process, several parameters were investigated, and the main variables were optimized using CCD-based RSM.

Pectin, a natural polysaccharide, holds versatile applications in food and pharmaceuticals. However, there is a need for further exploration into extracting novel functional fractions and characterizing them thoroughly. In this study, a sequential extraction approach was used to obtain three distinct lemon pectin (LP) fractions from lemon peels (Citrus Eureka): LP extracted with sodium acetate (LP-SA), LP extracted with ethylenediaminetetraacetic acid (LP-EDTA), and LP extracted with sodium carbonate and sodium borohydride (LP-SS).

Unlabelled: The gut microbiota of poultry is influenced by a variety of factors, including feed, drinking water, airborne dust, and footpads, among others. Gut microbiota can affect the immune reaction and inflammation in the lungs. To investigate the effect of gut microbiota variation on lung inflammation induced by PM (fine particulate matter) in broilers, 36 Arbor Acres (AA) broilers were randomly assigned to three groups: control group (CON), PM exposure group (PM), and PM exposure plus oral antibiotics group (PMA).
