Abstract The growing global demand for sustainable, low-carbon energy has intensified research into biomass pyrolysis as a promising route for biofuel production. This study provides a comprehensive investigation of the kinetic and thermodynamic behavior of faba bean hulls, an un...

Role of venous excess ultrasound (VExUS) protocol in grading systemic venous congestion in adult Egyptian patients with congestive heart failure: a prospective study

Abstract Background Heart failure (HF) is a prevalent condition associated with substantial morbidity and mortality globally. Persistent congestion, particularly systemic venous congestion, can precipitate organ dysfunction and is linked to adverse clinical outcomes, including in...

Temperature‐Controlled Synthesis of Fe‐Based Graphite Nanocomposites for Sustainable Photocatalysis and Electrocatalysis Application

ABSTRACT This study reports the temperature‐controlled synthesis of iron‐based graphite nanocomposites prepared via a sol–gel route followed by electro‐spraying and evaluates their photocatalytic and electrocatalytic performance. At a calcination temperature of 750°C, the materia...

Aucubin Ameliorates Alloxan-Induced Diabetic Liver Injury in Association with Modulation of the Nrf2/HO-1 Antioxidant Axis and NF-κB-Associated Inflammatory and Apoptotic Signaling

Diabetes mellitus is associated with progressive hepatic injury driven by oxidative stress, inflammation, and apoptosis. Aucubin, a natural iridoid glycoside, possesses potent antioxidant and anti-inflammatory activities; however, its hepatoprotective mechanisms in diabetic liver...

Cytomegalovirus Latency Fuels Inflammation Following Myocardial Infarction

BACKGROUND: Epidemiological studies have consistently associated cytomegalovirus (CMV) seropositivity with adverse cardiovascular outcomes. However, the mechanisms by which cytomegalovirus infection impacts pathophysiology in the heart remain poorly understood. In this study, we...

Audiological profile in children with Incomplete Partition type I: case series

Abstract Introduction Incomplete Partition (IP) malformation constitutes 40% of Inner ear anomalies (IEAs) whereas the prevalence of IP-I was estimated to be around 20% of IEAs and around 2% of all cochlear malformation. IP-I has worse morphological and functional features than I...

Optimizing genotype and nitrogen management for improved yield and agronomic efficiency in dry direct seeded rice under temperate ecology

Rice production through conventional transplanting is becoming increasingly difficult because of limited water resources and labor shortages. Dry direct-seeded rice (DSR) offers a practical alternative with lower water and labor requirements. However, the success of DSR depends o...
