This study investigates the determinants of green energy penetration in the Next Eleven (N-11) economies over the period 2000–2022, with a particular focus on the roles of foreign direct investment (FDI), green transition, governance quality, industrial growth, and urbanization. The primary objective of the study is to assess how investment flows, structural transformation, and institutional capacity jointly shape the adoption of renewable energy in fast-growing emerging economies. To achieve this goal, the study employs a second-generation panel econometric and machine-learning framework that

BACKGROUND: Antibody-drug conjugates (ADCs) are emerging anti-cancer agents. The folate receptor alpha (FOLRα)-directed ADC mirvetuximab soravtansine recently demonstrated clinical activity in platinum-resistant ovarian cancer, with other ADCs currently in development. The relative expression of FOLRα and other ADC targets is largely unknown across ovarian cancer histotypes. METHODS: Expression levels of the ADC targets FOLRα, TROP2 and B7-H4 were assessed by immunohistochemistry in patient cohorts using tumour tissue microarrays of the major ovarian cancer histotypes: high grade serous (HGSOC

Osteoarthritis (OA) is a debilitating joint disorder that causes chronic pain, inflammation, and detrimental bone alterations. Despite significant advances in understanding OA pathogenesis, current therapeutic strategies remain inadequate in halting disease progression or providing effective pain relief, highlighting unmet clinical needs. Recent insights into OA nociceptive pathways, inflammatory mediators, and organelle dysfunction have revealed promising therapeutic targets. Specifically, OA progression is driven by mitochondrial dysfunction (marked by accumulated damaged mitochondria with e
