The future of pyrogenicity testing: Phasing out the rabbit pyrogen test. A meeting report
Biologicals. 2023 Aug 27;84:101702. doi: 10.1016/j.biologicals.2023.101702. Online ahead of print.ABSTRACTThe rabbit pyrogen test (RPT) was the benchmark for pyrogenicity testing, but scientific advancements have provided innovative and humane methods, such as the in vitro monocyte-activation test (MAT). However, transitioning from the RPT to the MAT has been challenging. The European Directorate for the Quality of Medicines & HealthCare, the Council of Europe, and the European Partnership for Alternative Approaches to Animal Testing jointly hosted an international conference entitled "The future of pyrogenicity testin...

Report of the third conference on next-generation sequencing for adventitious virus detection in biologics for humans and animals
Biologicals. 2023 Jul 19;83:101696. doi: 10.1016/j.biologicals.2023.101696. Online ahead of print.ABSTRACTNext-generation sequencing (NGS) has been proven to address some of the limitations of the current testing methods for adventitious virus detection in biologics. The International Alliance for Biological Standardization (IABS), the U.S. Food and Drug Administration (FDA), and the European Directorate for the Quality of Medicines and Healthcare (EDQM) co-organized the "3rd Conference on Next-generation Sequencing for Adventitious Virus Detection in Biologics for Humans and Animals", which was held on September 27-28, 20...

Fight Aging! Newsletter, July 17th 2023
In conclusion, the longevity-associated genotype of FLT1 may confer increased lifespan by protecting against mortality risk posed by hypertension. We suggest that FLT1 expression in individuals with longevity genotype boosts vascular endothelial resilience mechanisms to counteract hypertension-related stress in vital organs and tissues. Resistance Exercise Slows the Onset of Pathology in a Mouse Model of Alzheimer's Disease https://www.fightaging.org/archives/2023/07/resistance-exercise-slows-the-onset-of-pathology-in-a-mouse-model-of-alzheimers-disease/ With the caveat that mouse models of Alzheimer's...

In conclusion, among Swedish middle-aged subjects, nearly two-thirds showed complete fatty degeneration of thymus on CT. Age-Related Dysfunction of Water Homeostasis https://www.fightaging.org/archives/2023/06/age-related-dysfunction-of-water-homeostasis/ Dehydration can be an issue in older people. As in every complex system in the body, the mechanisms by which hydration is regulated become dysfunctional with advancing age. Researchers here look at the brain region responsible for regulating some of the response to dehydration, cataloging altered gene expression in search of the more important mechani...

Conclusions Implanted Hair Follicle Cells Produce Remodeling of Scar Tissue Assessment of Somatic Mosaicism as a Biomarker of Aging The Gut Microbiome of Centenarians https://www.fightaging.org/archives/2023/01/the-gut-microbiome-of-centenarians/ The state of the gut microbiome is arguably as influential on health as exercise. Various microbial species present in the gut produce beneficial metabolites, such as butyrate, or harmful metabolites, such as isoamylamine, or can provoke chronic inflammation in a variety of ways. An individual can have a better or worse microbiome, assessing these and other fu...

In conclusion, circulating monocytes in older adults exhibit increased expression of activation, adhesion, and migration markers, but decreased expression of co-inhibitory molecules. MERTK Inhibition Increases Bone Density via Increased Osteoblast Activity https://www.fightaging.org/archives/2022/12/mertk-inhibition-increases-bone-density-via-increased-osteoblast-activity/ Bone density results from the balance of constant activity on the part of osteoblasts and osteoclasts, the former building bone, the latter breaking it down. With advancing age, the balance of activity shifts to favor osteoclasts, prod...

IABS/DCVMN webinar on next generation sequencing
This report is for the webinar that was organized by the International Alliance for Biological Standardization (IABS) and the Developing Countries Vaccine Manufacturers Network (DCVMN), held on July 20, 2022, as an introduction to the technical and bioinformatics concepts of NGS and to some of the strengths and limitations of using the technology for those working in vaccine production or development. The current state of scientific knowledge and readiness of NGS to replace or supplement the current viral tests was further discussed in the 3rd Conference on NGS for Adventitious Virus Detection in Biologics for Humans and A...
