Effects of cage size on the natural behavior, serum parameters, production performance and hypothalamic mRNA expression profiles of laying hens.

The objective of this study was to evaluate the effects of cage size on the natural behavior, serum biochemistry, production performance and hypothalamic transcriptome profiles of laying hens. A total of 360 79-week-old hens were selected and randomly assigned to three groups (with five replicates each) with different cage sizes: large cages (LCs), medium cages (MCs), and small cages (SCs). The stocking density remained consistent across all groups throughout the experimental period.

Advancing Cancer Vaccines with Radionuclide Imaging.

Cancer vaccines are emerged as a beacon of hope in the fight against cancer. However, the lack of effective methods to directly observe their in vivo behavior and monitor therapeutic responses hinders their translation into clinical settings. Radionuclide imaging allows for non-invasive and real-time visualization of vaccine biodistribution and immunological response, offering valuable insights into the effectiveness of cancer vaccines and aiding in patient stratification.

Identification of a Novel Vascular Endothelial Growth Factor Receptor-3-Targeting Peptide for Molecular Imaging of Metastatic Lymph Nodes.

Because of the insidious nature of lymphatic metastatic cancer, accurate imaging tracing is very difficult to achieve in the clinic. Previous studies have developed the LARGR peptide (named TMVP1) as a radiotracer for vascular endothelial growth factor receptor-3 (VEGFR-3) imaging in cancer. However, its affinity for the target remains insufficient, resulting in low imaging sensitivity.

Motivation: Neoantigens, derived from somatic mutations in cancer cells, can elicit anti-tumor immune responses when presented to autologous T cells by human leukocyte antigen. Identifying immunogenic neoantigens is crucial for cancer immunotherapy development. However, the accuracy of current bioinformatic methods remains unsatisfactory.

The association between dietary zinc intake and osteopenia, osteoporosis in patients with rheumatoid arthritis.

Background: Diet has been shown to be associated with rheumatoid arthritis (RA), of which osteoporosis is the most common and important complication, and zinc has been shown to inhibit the inflammatory response, but studies on the relationship between dietary zinc and osteoporosis in patients with RA are limited and inconclusive. In this study, we aimed to explore the relationship between dietary zinc intake and osteoporosis or osteopenia in patients with RA.

Methods: Data on RA patients were derived from the National Health and Nutrition Examination Survey (NHANES) 2007 to 2010, 2013 to 2014, and 2017 to 2020.

VP3 protein of Senecavirus A promotes viral IRES-driven translation and attenuates innate immunity by specifically relocalizing hnRNPA2B1.

Unlabelled: Viruses deploy sophisticated strategies to hijack the host's translation machinery to favor viral protein synthesis and counteract innate cellular defenses. However, little is known about the mechanisms by which Senecavirus A (SVA) controls the host's translation. Using a series of sophisticated molecular cell manipulation techniques, heterogeneous nuclear ribonucleoprotein A2B1 (hnRNPA2B1) was identified as an essential host factor involved in translation control in SVA-infected cells.

Development and Evaluation of DOTA-FAPI-Maleimide as a Novel Radiotracer for Tumor Theranostic with Extended Circulation.

This study aimed to evaluate a novel albumin-binding strategy for addressing the challenge of insufficient tumor retention of fibroblast activation protein inhibitors (FAPIs). Maleimide, a molecule capable of covalent binding to free thiol groups, was modified to conjugate with FAPI-04 in order to enhance its binding to endogenous albumin, resulting in an extended blood circulation half-life and increased tumor uptake. DOTA-FAPI-maleimide was prepared and radiolabeled with Ga-68 and Lu-177, followed by cellular assays, pharmacokinetic analysis, PET/CT, and SPECT/CT imaging to assess the probe distribution in various tumor-bearing models.

Peptide-based PET tracer targeting LAG-3 for evaluating the efficacy of immunotherapy in melanoma.

Background: Lymphocyte activation gene 3 (LAG-3) is expressed on activated immune cells and has emerged as a promising target for immune checkpoints blockade. However, conflicting findings have been reported regarding the association between LAG-3 expression in tumors and patient prognosis, indicating the need for further investigation into the significance of LAG-3 expression levels in tumor therapies. In this study, Ga-NOTA-XH05, a novel peptide-based positron emission tomography (PET) tracer targeting LAG-3, was constructed to non-invasively detect LAG-3 expression in melanoma after CpG oligonucleotide (CpG) treatment and explore the relationship between LAG-3 expression and therapeutic effect.

Liver-specific delivery of spherical DNA frameworks for alleviation of hepatic ischemic reperfusion injury.

DNA nanostructures have long been developed for biomedical purposes, but their controlled delivery in vivo proposes a major challenge for disease theranostics. We previously reported that DNA nanostructures on the scales of tens and hundreds nanometers showed preferential renal excretion or kidney retention, allowing for sensitive evaluation and effective protection of kidney function, in response to events such as unilateral ureter obstruction or acute kidney injury. Encouraged by the positive results, we redirected our focus to the liver, specifically targeting organs noticeably lacking DNA materials, to explore the interaction between DNA nanostructures and the liver.

Investigating the efficacy of vacuum sealing drainage versus traditional negative pressure drainage in treating deep incision infections following posterior cervical internal fixation-a retrospective cohort study.

Background: Assessing the efficacy and safety of Vacuum Sealing Drainage (VSD) in treating deep incision infections (DII) following posterior cervical internal fixation.

Methods: We retrospectively studied the clinical effects of VSD and Traditional Negative Pressure Drainage (TND) on 12 patients with deep incision infection after posterior cervical fixation surgery who were treated in our department from 2012 to 2020. A comparison of patient-related factors (age, gender, BMI, comorbidities, initial internal fixation surgery segment, preoperative laboratory inflammation indicators) and surgical-related factors (postoperative duration of fever, positive rate of drainage fluid bacterial culture, Visual Analogue Scale (VAS) score at 3 days after surgery, laboratory indicators at 3 days after surgery, debridement frequency and drainage time, hospital stay, internal fixation retention rate, and infection recurrence rate) between the VSD group and the TND group was conducted using independent sample t tests to draw experimental conclusions.
