Laparoscopic exploration (LE) is crucial for diagnosing intra-abdominal metastasis (IAM) in advanced gastric cancer (GC). However, overlooking single, tiny, and occult IAM lesions during LE can severely affect the treatment and prognosis due to surgeons' visual misinterpretations. To address this, we developed the artificial intelligence laparoscopic exploration system (AiLES) to recognize IAM lesions with various metastatic extents and locations.

Quaternary ammonium compounds (QACs) served as broad spectrum antimicrobial agents are widely applied for surface disinfection, skin and mucous disinfection, and mouthwash. The daily applications of QACs have significantly increased, especially during the COVID-19 pandemic. However, the environmental residues of QACs have demonstrated harmful impacts on the environment, leading to an increase in environmental contamination, resistant microbes and disruption of microecology.

We designed, synthesized, and evaluated the antitumor activity of a series of novel quinazoline-4-(6-methoxytetrahydroquinoline) analogues. Among the tested compounds, 4a4 exhibited the most potent antiproliferative activities across four human cancer cell lines with half-maximal inhibitory concentration (IC) values ranging from 0.4 to 2.

The purple sweet potato anthocyanins (PSPA) are known for their diverse health benefits, yet their hepatoprotective effects and the mechanisms by which they combat liver fibrosis have not been thoroughly investigated. This study aimed to elucidate these effects by employing a carbon tetrachloride (CCl)-induced mouse model of liver fibrosis. We conducted a comprehensive analysis of the effects of PSPA on liver injury, oxidative stress, inflammation, and fibrosis-related signaling pathways.

Background: Long-distance road transportation is a common practice in the beef industry, frequently resulting in bovine respiratory disease (BRD) and compromised growth performance. However, a comprehensive investigation integrating clinical performance, physiological conditions, and nasopharyngeal microflora remains lacking.

Methods: This study aimed to evaluate the respiratory health and immunometabolic status of 54 beef calves subjected to a 3000-km journey.

  • - Candida albicans is a common fungus that causes oral candidiasis, especially in vulnerable populations like the elderly and those with weakened immune systems, leading to challenges due to drug resistance and side effects of current treatments.
  • - Researchers found that moxidectin, an antiparasitic drug, enhances the effectiveness of existing antifungal drugs called polyenes by activating the ergosterol biosynthesis pathway in Candida albicans, which is crucial for the fungi's survival.
  • - In experiments, moxidectin combined with low doses of polyenes significantly reduced Candida albicans infection and inflammation in a mouse model, indicating its potential as a promising treatment option in clinical practice.

Transportation, an unavoidable process in livestock farming, causes metabolic disorders in the body, which then lead to endocrine disruption, being immunocompromised, and growth suppression. Lipid metabolism dysregulation is a critical phenotype induced by transportation. The liver is a vital organ in lipid metabolism, with a role in both lipid synthesis and lipolysis.

  • The study evaluates the clinical importance of methylation levels of DDR1 and CtBP genes in assessing the severity of acute pancreatitis (AP) using blood samples from both patients and healthy individuals.
  • Key findings showed that the methylation level of the CtBP1 gene and the MCTSI score were independent predictors of severe acute pancreatitis (SAP), with high accuracy values.
  • The research suggests that while CtBP1 methylation is a reliable predictor of SAP, the methylation levels of DDR1, SPINK1, CtBP2, and CFTR genes also have potential in identifying acute pancreatitis cases.

  • This study investigates how resistin (RETN), an adipocyte hormone, affects autophagy and inflammation in bovine alveolar macrophages (BAMs).
  • The researchers found that RETN treatment increased autophagosomes and altered protein expressions related to autophagy, specifically enhancing the LC3II/LC3I ratio while decreasing p62 levels.
  • RETN activated the AMPK/mTOR signaling pathway which is crucial for autophagy regulation and also reduced inflammation markers compared to the LPS treatment alone.

  • - The study aims to create a standardized MRI classification for brucellosis spondylitis (BS) to improve treatment methods and post-treatment follow-up.
  • - It analyzed data from 615 patients diagnosed with BS over 12 years, identifying key MRI characteristics and categorizing them into three main types, with Type II being the most common.
  • - The findings suggest that using MRI features can enhance the diagnosis and treatment strategies for BS, providing a framework for ongoing patient management.

  • - The study investigated MRI features to identify and differentiate the morphological and functional abnormalities associated with Parkinson's disease (PD) compared to normal aging changes in healthy individuals.
  • - Participants included 32 PD patients, 42 age-matched healthy controls (HCg1), and 33 younger controls (HCg2), with a focus on assessing cortical volume and brain connectivity.
  • - Results showed reduced cortical volumes in the frontal lobe and temporal lobe for HCg1 compared to HCg2, while PD patients didn't have significant volume differences from HCg1 but displayed lower connectivity, highlighting distinct changes caused by PD versus age-related changes.

Proliferation of renal tubular epithelial cells (TEC) is essential for restoring tubular integrity and thereby to support renal functional recovery from kidney ischemia/reperfusion (KI/R) injury. Activation of transcriptional factor c-Myc promotes TEC proliferation following KI/R; however, the mechanism regarding c-Myc activation in TEC is incompletely known. Heat shock protein A12A (HSPA12A) is an atypic member of HSP70 family.

The () cytotoxin-associated gene pathogenicity island (PAI) encodes 31 genes that assemble the type IV secretion system (T4SS) apparatus, which includes structures such as the outer membrane core complex, periplasmic ring, inner membrane complex and bacterial hairs. These proteins interact with each other to inject CagA into the host gastric epithelium. There are also individual unique functions that help interfere with host cellular pathways, modulate the immune response and colonize the host for a long time.
