Biological clocks and other molecular biomarkers of aging are difficult to implement widely in a clinical setting. In this study, we used routinely collected hematological markers to develop an aging clock to predict blood age and determine whether the difference between predicted age and chronologic age (aging gap) is associated with advanced aging in mice. Data from 2,562 mice of both sexes and three strains were drawn from two longitudinal studies of aging.

The aim of this study was to formulate novel biomixtures with the ability to dissipate globally used pesticides. For this, an effective stabilization of two wastes, poultry litter and activated sewage sludge, was achieved through a combination of composting and vermicomposting, with the aid of the earthworm Eisenia fetida. Hence, two different mixtures were prepared combining the wastes with and without the addition of sewage sludge, and their physicochemical and microbiological characterization was examined during both processes.

The exponential scientific and technological progress during the past 30 years has favored the comprehensive characterization of aging processes with their multivariate nature, leading to the advent of Big Data in preclinical aging research. Spanning from molecular omics to organism-level deep phenotyping, Big Data demands large computational resources for storage and analysis, as well as new analytical tools and conceptual frameworks to gain novel insights leading to discovery. Systems biology has emerged as a paradigm that utilizes Big Data to gain insightful information enabling a better understanding of living organisms, visualized as multilayered networks of interacting molecules, cells, tissues and organs at different spatiotemporal scales.

Article Synopsis
  • * A study placed 14-month-old female mice on various dietary plans, focusing on how CR and TRF with different eating windows affect their health, disease progression, and lifespan.
  • * Results indicated that CR led to more significant health benefits, unique serum profiles, and increased lifespan compared to TRF, suggesting that prolonged fasting combined with lower energy intake offers better advantages, especially in older female mice.

Heat stress in poultry is a major concern, especially in regions with hot summers and scarce cooling infrastructure. Dietary supplementation with antioxidants, such as polyphenols, has risen as a strategy to mitigate the physiological consequences of heat stress. A by-product of the extraction of oil from chia seeds, which is discarded if not used, could be a possible source of polyphenols.

Article Synopsis
  • Organisms have evolved internal timing systems to manage physiological processes, but these are often overlooked in areas like dietary supplementation for farm animals under environmental stress.
  • Research tested the hypothesis that thymol could help alleviate heat stress effects in Japanese quail, finding that its benefits are influenced by both long-term and short-term timing.
  • Results showed that thymol supplementation significantly improved conditions during the mornings of the first week, emphasizing the need to consider timing in dietary strategies for animals under stress.

Avian require comfortable temperatures for optimal development and heat stress is a high concern in warm weather countries. We aimed to assess the dynamics of immunoendocrine and biochemical variables responses of birds exposed to a heat stressor applied during daylight hours, during the chronic stress and the recovery periods. We hypothesize that variables involved in the birds response will be differentially and gradually modified during those periods.
