Senolytic treatment attenuates immune cell infiltration without improving IAV outcomes in aged mice

Aging Cell, Volume 24, Issue 4, April 2025.
Aging exacerbates IAV infection severity in aged mice. Senolytic treatment fail to improve IAV morbidity and survival in aged mice. Senolytics suppress immune infiltration into the lungs. Acute senolytic treatment does not reduce senescence markers. Abstract Aging is a major risk factor for poor outcomes following respiratory infections.

Protective Effect of Trehalose Sugar on Amyloid-Membrane Interactions using BLM Electrophysiology [PDF]

Alzheimer's disease (AD) is a neurodegenerative disease characterized by dementia and memory loss in the elderly population. The amyloid-$\beta$ peptide (A$\beta$ 1-42) is one of the main pathogenic factors in AD and is known to cause damage to neuronal cellular membranes.

A Lipid Rafts Theory of Alzheimer's Disease [PDF]

arXiv, 2023
I present a theory of Alzheimer's Disease (AD) that explains its symptoms, pathology, and risk factors. To do this, I introduce a new theory of brain plasticity that elucidates the physiological roles of AD-related agents. New events generate synaptic and branching candidates competing for long-term enhancement. Competition resolution crucially depends

Piezo1 exacerbates inflammation‐induced cartilaginous endplate degeneration by activating mitochondrial fission via the Ca2+/CaMKII/Drp1 axis

Aging Cell, Volume 24, Issue 4, April 2025.
Schematic illustration of the role of Piezo1 in inflammation‐induced CEP degeneration. Piezo1 promotes Drp1 S616 phosphorylation and mitochondrial translocation, then triggers mitochondrial fragmentation and dysfunction via the Ca2+/CaMKII signalling.

Tissue fibrosis: a principal proof for the central role of Misrepair in aging [PDF]

arXiv, 2015
Tissue fibrosis is the phenomenon that a tissue has progressive deposition of collagen fibers with age. Tissue fibrosis is associated with aging of most of our organs, and it is the main pathology in arteriosclerosis, chronic bronchitis/emphysema, and benign prostatic hyperplasia.

Polymorphous low grade adenocarcinoma-an unusual presentation [PDF]

, 2010
Polymorphous low-grade adenocarcinoma (PLGA) is a neoplasm that occurs frequently in the mucosa of the soft and hard palates, in the buccal mucosa and in the upper lip and is very rare within the nasopharynx. We present a case of PLGA, which presented as

Immunosenescence Profile Is Associated With Increased Susceptibility to Severe COVID‐19

Aging Cell, EarlyView.
(A) A previous immunosenescence profile in individuals infected with SARS‐CoV2 creates a permissive environment for progression to severe COVID‐19: higher inflammaging, accumulation of exhausted/senescent T cells, an oligoclonal B‐cell repertoire, and accelerated epigenetic age.

An exceptional case of peritoneal cystic echinococcosis in a domestic cat in Australia

Australian Veterinary Journal, Volume 103, Issue 5, Page 254-260, May 2025.
A case of peritoneal cystic echinococcosis (CE) in a domestic cat was reported from Queensland, Australia. Physical examination of the cat indicated a large, distended abdomen, which when palpated appeared to be fluid‐filled. Ultrasonography showed numerous cysts with hyperechoic walls and anechoic contents within the cat's abdominal cavity.
