Soaking Water Management Strategies for Enhanced Quality of Parboiled Rice

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Parboiling is a hydrothermal process that alters rice physicochemical and nutritional properties. The soaking step is crucial, influencing off‐flavor formation, mineral retention, and effluent quality. This study evaluated five soaking water (SW) management strategies combining different frequencies and volumes of SW ...

Mechanical Behaviour of Vacuum‐Infused GFRP Composites at Elevated Temperatures—Influence of Fibre Architecture

Fire and Materials, EarlyView.
ABSTRACT This study addresses the influence of fibre architecture on the mechanical properties of vacuum‐infused glass fibre reinforced polymer (GFRP) composites at elevated temperatures (ET). Laminates with three different fibre configurations—unidirectional (UD), bidirectional 0°/90° cross‐ply (BD), and ±45° off‐axis angle‐ply (OA) – were tested in ...

Systemic and Local Adiposity in the Bone Marrow Microenvironment Associated With Improved Prognosis in Hodgkin Lymphoma: Imaging and Molecular Analysis

International Journal of Cancer, Volume 159, Issue 3, Page 782-796, 1 August 2026.
Schematic overview of systemic and bone marrow‐specific adiposity in Hodgkin Lymphoma (HL). Body Mass Index was associated with bone marrow (BM) involvement, relapse, and mortality (1). In contrast, increased yellow marrow density was associated with poorer prognosis (2).

How does leaf age affect performance? A comparative study of essential oils from young and mature Eucalyptus globulus leaves in crop protection

Pest Management Science, Volume 82, Issue 8, Page 7510-7525, August 2026.
Leaf age influences metabolomic profiling but not bioactivity of Eucalyptus globulus essential oils. Leaf age affects volatile levels of young and adult E. globulus oils, but not their bioactivity. Young leaf essential oil had higher contents of α‐ and β‐pinene. AEEO had higher levels of 1,8‐cineole and trans‐pinocarveol.

Exploring Biological Properties of Manganese(II)‐Phenanthroline‐Based Complexes: In Vitro Insights

ChemistrySelect, Volume 11, Issue 29, 3 August 2026.
Four Mn(II) complexes with phenanthroline derivatives were studied. These compounds were tested against several parasites and different human cancer cells. Despite its cytotoxicity on breast cancer, DNA seems not to be the main biological target. These complexes can drive the design and development of new metal‐based agents with improved biological ...
