ABSTRACT Early diagnosis of acute promyelocytic leukemia (APL), driven by PML‐RARA oncoprotein, is vital for survival, as delays can cause fatal coagulopathy without prompt therapeutic intervention of all‐trans retinoic acid and arsenic trioxide. Although APL is diagnosed using microscopy, immunophenotyping, and FISH/PCR for PML‐RARA, morphological ...

Structural Analysis and Inhibitor Modeling of Bacterioferritin From Brucella abortus
ABSTRACT Iron homeostasis in various pathogenic bacteria is regulated by bacterioferritins (Bfr) which function to store Fe3+ and release Fe2+ as needed for metabolic processes. The Bfr structure consists of 18 kDa subunits in which dimer pairs bind a heme molecule and are assembled into a highly symmetrical 24‐meric spherical structure with an ...

This article reports the first genome sequence of a UK Alternaria brassicae isolate. Dual RNA‐sequencing profiling of A. brassicae‐infected Brassica juncea leaves identified differentially expressed genes involved in pathogenicity and host response pathways in moderately resistant Sej‐2 (2) and moderately susceptible Pusa Jaikisan cultivars.

Biocarbon Suitability Evaluation for Direct Injection in Blast Furnace Ironmaking
This study examines densified biocarbon for direct injection in blast furnace ironmaking to reduce greenhouse gas (GHG). Enhanced burnout performance, along with favorable reactivity and carbon structure of the combustion residue, supports its suitability for blast furnace injection. Modeling results indicate that up to a 27% reduction in GHG emissions
