Parkinson's disease (PD) is a neurodegenerative disorder primarily characterized by motor impairments such as bradykinesia, tremor, and rigidity. Its neuropathological hallmarks include the progressive loss of dopaminergic neurons in the substantia nigra pars compacta (SNc) and the aggregation of α-synuclein (α-syn) into Lewy bodies (LBs), which gradually spread to other central nervous system regions and peripheral tissues. The etiology of PD is multifactorial, involving a complex interplay of genetic predisposition, aging, environmental exposures, and lifestyle factors. Disease pathogenesis

Mitochondrial dysfunction represents a central hallmark of aging and a broad spectrum of chronic diseases, ranging from metabolic to neurodegenerative and ocular disorders. Nicotinamide riboside (NR), a vitamin B3 derivative and efficient precursor of NAD+ (nicotinamide adenine dinucleotide), and berberine (BBR), an isoquinoline alkaloid widely investigated in metabolic regulation, have independently emerged as promising mitochondrial modulators. NR enhances cellular NAD+ pools, thereby activating sirtuin-dependent pathways, stimulating PGC-1α–mediated mitochondrial biogenesis, and triggering

BACKGROUND: There are no validated tools for the clinical neurological assessment of patients with leptomeningeal metastases (LM). However, clinical examination during the course of the disease guides medical management and is part of response assessment in clinical trials. Because neuroimaging may not always be obtained owing to rapid clinical deterioration, clinical neurological assessment of LM is essential, and standardization is important to minimize rater disagreement. METHODS: The Response Assessment in Neuro-oncology-LM group launched a 2-step process, aiming at improving and standardi

Genetic background is a major determinant of disc degeneration, a leading cause of chronic back pain and disability. Herein, we demonstrate that premature disc cell senescence contributes to early-onset degeneration in SM/J mice and test two systemic senotherapeutic strategies to mitigate it: Navitoclax (Nav.) and a cocktail of Dasatinib and Quercetin (DQ). While Nav. treatment did not improve severe degeneration in SM/J mice or senescence status, DQ-treated mice showed lower grades of degeneration and a decreased abundance of senescence markers, including p19ARF, p21, and the senescence-assoc

Metabolic dysfunction-associated steatotic liver disease (MASLD) is characterized by an exceptionally high global prevalence that is projected to continue rising in the near future. MASLD is strongly associated with a spectrum of cardiometabolic risk factors, and may itself, in turn, contribute to cardiovascular morbidity and mortality. This interconnection warrants the development of integrated treatment strategies targeting shared pathophysiological processes and addressing both hepatic, metabolic, and cardiovascular outcomes. In this work, we review the modern MASLD clinical development pip
