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 …

Thermophilic Adaptation of Anaerobic Sludge for Electricity Production
Abstract: Normal 0 false false false EN-US X-NONE X-NONE Anaerobic digestion of biogas inside the digester occurs in a particular temperature range. Research shows that the production can be increased by 33% by switching over from mesophilic temperature range (3040 ° C) to thermophilic temperature range (5060 ° C). Even then, biogas plants generally work in mesophilic range because a large amount of energy is required to maintain the high digester …

Mind-Gut Connection: The Psychosomatic Effects of Stress and Emotions on Digestive System
Abstract: Stress, understood as an immediate disruption to bodily equilibrium, triggers an adaptive or allostatic response that impacts gastrointestinal function both in the short and long term. The enteric nervous system communicates in both directions with the brain through parasympathetic and sympathetic pathways, collectively forming what is known as the brain-gut axis. Unani scholars describe stress as a response to the loss of something valuable, such as an opportunity, a desired …

Microbial Competition in the Rumen: Insights into Fermentation Kinetics, Host Health, and Environmental Sustainability
Abstract: Microbial competition within the rumen is a crucial determinant of fermentation efficiency, nutrient utilization, and overall host health in ruminant animals. The complex microbial community in the rumen comprises bacteria, protozoa, fungi, and archaea, all of which interact in intricate and often competitive ways to degrade feed and produce essential metabolites. This competition significantly influences fermentation kinetics, determining the rate and efficiency of carbohydrate, protein, and fat breakdown. Such microbial …
