Incorporating insect meals into poultry diets has emerged as a sustainable alternative to conventional feed sources, offering nutritional, welfare benefits, and environmental advantages. This study aims to monitor and compare volatile compounds emitted from raw poultry carcasses and subsequently from cooked chicken pieces from animals fed with different diets, including the utilization of insect-based feed ingredients. Alongside the use of traditional analytical techniques, like solid-phase microextraction combined with gas chromatography-mass spectrometry (SPME-GC-MS), to explore the changes in VOC emissions, we investigate the potential of S3+ technology.

Article Synopsis
  • The evolution of SARS-CoV-2 variants highlights the need for multivalent vaccines, leading to the development of SCTV01E, a tetravalent COVID-19 vaccine targeting variants Alpha, Beta, Delta, and Omicron BA.1.
  • A double-blind placebo-controlled trial showed SCTV01E had a vaccine efficacy of 69.4% against COVID-19 seven days post-vaccination, with higher efficacy rates in preventing symptomatic and all infections at 14 days.
  • The vaccine demonstrated a significant neutralizing antibody response against Omicron BA.5 and had mild reactogenicity, indicating its potential effectiveness against emerging SARS-CoV-2 variants.

We characterized the world's second case with ascertained extreme resilience to autosomal dominant Alzheimer's disease (ADAD). Side-by-side comparisons of this male case and the previously reported female case with ADAD homozygote for the APOE3 Christchurch (APOECh) variant allowed us to discern common features. The male remained cognitively intact until 67 years of age despite carrying a PSEN1-E280A mutation.

Successful pancreatic ductal adenocarcinoma (PDAC) immunotherapy necessitates optimization and maintenance of activated effector T cells (Teff). We prospectively collected and applied multi-omic analyses to paired pre- and post-treatment PDAC specimens collected in a platform neoadjuvant study of granulocyte-macrophage colony-stimulating factor-secreting allogeneic PDAC vaccine (GVAX) vaccine ± nivolumab (anti-programmed cell death protein 1 [PD-1]) to uncover sensitivity and resistance mechanisms. We show that GVAX-induced tertiary lymphoid aggregates become immune-regulatory sites in response to GVAX + nivolumab.
