Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function
FEBS Open Bio, EarlyView.We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Practical guidance on the application of R-K integration method in finite element analysis of creep damage problem [PDF]
A practical user guidance of Runge-Kutta (R-K) integration method with the context of non-linear time dependent finite element analysis (FEA) was proposed in this paper.

FEBS Open Bio, EarlyView.Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death
FEBS Open Bio, EarlyView.Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

A damage-plasticity model for the dynamic failure of concrete
, 2011 A constitutive model based on the combination of damage mechanics and plasticity is developed to analyse concrete structures subjected to dynamic loading. The aim is to obtain a model, which requires input parameters with clear physical meanings.

Mechanisms of Perinatal Brain Damage
Annals of Medicine, 1991 Although the perinatal brain is more resistant towards hypoxia-ischemia than at any later stage of development, perinatal asphyxia still contributes to permanent brain damage in survivors. This short review focuses on the discussion of mechanisms of late neuronal death, i.e.

DNA damage and repair mechanism. [DNA damage and repair mechanisms] [PDF]
, 1976 The ability of cells to survive in an environment specifically damaging to its DNA can be attributed to a variety of inherent repair mechanisms. This is a form of repair in which alterations are directly reversed to their original form. This reversibility is exemplified by the photoreactivation of ultraviolet-induced pyrimidine dimers.

FEBS Open Bio, EarlyView.Early‐life exposure to a high‐fat diet altered intact Achilles tendons in rat offspring, making them thinner, stiffer, and molecularly distinct even without injury. These findings suggest that developmental high‐fat diet exposure may impair tendon quality and increase susceptibility to mechanical overload or tendon injury later in life.

A Combined High and Low Cycle Fatigue Life Prediction Model for Wind Turbine Blades
Applied SciencesA novel method is proposed for a combined high and low cycle fatigue (CCF) life prediction model based on Miner’s rule, incorporating load interactions and coupled damage effects to evaluate the fatigue life of wind turbine blades under CCF loading.
