Type IV Monteggia-equivalent fracture in an adult: a case report [PDF]

Clinics in Shoulder and Elbow, 2023
A Monteggia fracture is a proximal ulnar fracture with proximal radioulnar ligamentous instability. While there is no precise definition, Monteggia-equivalent fractures are generally considered Monteggia fractures accompanied by radial head fractures ...

Bilateral Variation of Radial Artery: Two Case Reports and Literature Review [PDF]

Journal of Research in Applied and Basic Medical Sciences, 2022
The radial artery is useful in interventional treatment, and its variation is important for the clinician consideration. During the dissection of Sudanese adult 83-old-male cadaver, multiple upper limbs, a rare vascular variation, was observed in cases 1

Radial variation of fiber morphology and wood density of the commercial species Drypetes sp. and Myroxylon balsamum

Maderas: Ciencia y Tecnología
Studying the radial variation of wood density, an essential biophysical property that reflects the quality of commercial species in tropical forests, is crucial. Understanding how these variations relate to wood anatomy provides valuable insights.

Radial Variations in Surface Characteristics of Pine Wood (Pinus merkusii) Modified with Glycerin–Citric Acid

Jurnal Ilmu Pertanian Indonesia
Pine wood (Pinus merkusii) is a native Indonesian softwood species with high commercial value but low natural durability (class IV), limiting its use in outdoor applications. This study modified the pine wood using a 20% glycerin–citric acid solution (1:

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

FEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
