FDA/EMA pathways and regulatory frameworks for aging interventions
Interventions that extend lifespan in animal models could, in principle, decelerate the aging process as a whole. Alternatively, they could act by suppressing one or more individual late-life pathologies that contribute to mortality. Here we …
BACKGROUND AND OBJECTIVES: Centenarians represent a growing demographic that remains under-theorized in gerontology. Subsumed within the broader category of the oldest old, they are often examined through a biomedical lens, which tends to frame extreme …
Sapindus saponaria L. (S. saponaria), popularly known as "saboeiro" or "monkey soap," is traditionally used in South America for inflammatory, infectious, and dermatological conditions. Despite its wide use, toxicological data remain limited, and the presence …
INTRODUCTION: Skin aging, marked by wrinkles, volume loss, and reduced hydration, has driven growing interest in minimally invasive aesthetic treatments to restore skin quality and appearance. This study aimed to evaluate the efficacy and safety …
The bone marrow niche (BMN) plays a central role in regulating hematopoietic stem-cell (HSC) maintenance, lineage commitment, and immune homeostasis, while also supporting osteogenesis and maintaining skeletal integrity. Once considered static, the BMN is now …
AIMS: Numerous preclinical studies suggested that targeted inhibition of mammalian target of rapamycin (mTOR) may be beneficial for the treatment of osteoporosis. However, the relevance of these findings to human populations remains unclear. We hypothesized …
BACKGROUND: Poly-L-lactic acid (PLLA) is a biostimulatory injectable that restores midfacial volume through collagen neogenesis rather than gel-based filling. Controlled clinical evidence directly quantifying PLLA's volumetric efficacy remains limited. OBJECTIVES: To evaluate the efficacy, safety, …
BACKGROUND: Concomitant abdominoplasty and breast surgery has gained popularity among women seeking comprehensive esthetic rejuvenation. However, concerns remain regarding whether combining procedures increases perioperative risk compared with performing them in isolation. PURPOSE: Compare complication rates …
Population-level sex biases in human neuroanatomy have been highly debated, with prior literature often limited by narrow age windows and simplistic assumptions about how brain regions scale with sex differences in average total brain size. …
Researchers found that corylin, a flavonoid from a traditional medicinal plant, extended lifespan and improved stress resistance in C. elegans worms by activating two key proteins that enhance cellular housekeeping and mitochondrial health. While promising, …
Background: GLP1 receptor agonists (GLP1RAs) and SGLT2 inhibitors (SGLT2Is) have established cardiovascular benefits for patients with type 2 diabetes mellitus (T2DM), with similar class-level effectiveness found in previous studies. However, real-world comparative effectiveness assessments of …
Glioblastoma is a highly aggressive primary brain tumour marked by extensive genomic and epigenomic alterations, cellular heterogeneity, and therapeutic resistance. Despite maximal surgical resection followed by chemoradiotherapy, median survival remains approximately 15 months, reflecting the …
Researchers gave aging mice rapamycin and found it prevented the normal decline in movement and motor control, with females benefiting more than males. The benefits appear linked to reduced oxidative stress and cellular stress in …
This review examines how lysosomes—cellular recycling centers—actively regulate aging through two newly discovered signaling pathways (lysosomal surveillance response and transgenerational lysosomal signaling) and the protein TFEB. These findings suggest targeting lysosomal activity could be a …
BackgroundAs dementia prevalence rises globally, it is critical to find preventions that target modifiable risk factors like blood pressure. Pulse pressure (PP), a marker of arterial stiffness, contributes independently to cognitive impairment. Yet, clinically interpretable …
Monocytes and macrophages are critically involved in the pathogenesis of atherosclerotic cardiovascular disease (ASCVD). Accumulating evidence indicates that monocytes and macrophages can develop innate immune memory and exhibit sustained pro-inflammatory properties in response to stimuli …
This review examines cellular senescence (aging cells that stop dividing) in muscle regeneration, finding that senescent cells play a dual role: they can briefly help repair muscle after injury, but when they accumulate in aging …
Energy-based devices are widely used for facial rejuvenation; as a result, an increasing proportion of patients presenting for facelift or necklift surgery have a history of prior treatment with ultrasound- or radiofrequency-based technologies. While the …
Researchers used computer simulations to map how a NAD+ analog activates SIR2, an enzyme linked to aging, by triggering a cascade of conformational changes that act like an internal relay system. They identified a previously …
The temporal coupling between cortical blood-oxygen-level-dependent (BOLD) activity and CSF inflow has recently been proposed as a non-invasive marker of glymphatic function, a brain-wide clearance system closely linked to sleep, neuromodulatory regulation and neurodegeneration. Reduced …
