Chemical shift assignments of DRB2 domains, a dsRNA binding protein in A. thaliana RNAi pathway.

In Arabidopsis thaliana, micro-RNA regulation is primarily controlled by DCL1, an RNase III enzyme, and its associated proteins. DCL1, together with DRB2, governs a specific group of miRNAs that induce the inhibition of target mRNA translation. DRB2 is a multi-domain protein containing two N-terminal dsRNA binding domains (dsRBD) separated by a linker, followed by an unstructured C-terminal tail.

Cyclic cooperativity contributions determine the hydrogen bond strengths in molecular clusters.

Non-invasive volumetric ultrasound localization microscopy detects vascular changes in mice with Alzheimer's disease.

Alzheimer's Disease (AD) is the most common form of dementia and one of the leading causes of death. AD is known to be correlated to tortuosity in the microvasculature as well as decreases in blood flow throughout the brain. However, the mechanisms behind these changes and their causal relation to AD are poorly understood.

Focal Septic Arthritis Elicits Age and TLR2-Dependent Periarticular Bone Loss.

Introduction: Septic arthritis, primarily caused by (), is a severe joint infection that leads to joint and bone damage. lipoproteins (LPPs) bind to Toll-like Receptor 2 (TLR2), inducing arthritis and localized bone loss. Aging affects TLR2 immune response to pathogens.

Appraisal of the Fragments-In-Fragments Method for the Energetics of Individual Hydrogen Bonds in Molecular Crystals.

We report a direct application of the molecular tailoring approach-based (MTA-based) method to calculate the individual hydrogen bond (HB) energy in molecular crystal. For this purpose, molecular crystals of nitromalonamide (NMA) and salicylic acid (SA) were taken as test cases. Notably, doing a correlated computation using a large molecular crystal structure is difficult.
