Climate Change and Air Pollution Dynamics: Synergistic Effects and Mitigation Strategies
Abstract: Climate change and air pollution are deeply interlinked environmental problems that jointly exacerbate human health, ecosystem integrity, and economic well‑being. As global temperatures rise, shifts in meteorological conditions—such as increased heat, altered precipitation, and more frequent extreme weather events—modify pollutant generation, dispersion, chemical transformation, and removal processes. Meanwhile, many sources of air pollution are also sources of greenhouse gases (GHGs), giving rise to potential co‑benefits or trade‑offs when formulating mitigation …

Role of Impaired Digestion in Disease Pathogenesis: According to Unani System of Medicine
Abstract: The relationship between digestion and disease occupies a central position in Greco-Arab (Unani) medicine, as emphasized by classical physicians such as Ibn Sina and Al-Razi. In Unani medicine, digestion (Haḍm) is not confined to the gastrointestinal tract alone but represents a comprehensive physiological and metabolic process involving four sequential stages: gastric digestion (Haḍm-e-Mi‘dī), hepatic digestion (Haḍm-e-Kabidī), vascular digestion (Haḍm-e-‘Urūqī), and tissue digestion (Haḍm-e-‘Uḍwī). These stages are governed by Quwwat-e-Hāḍima (digestive …
