The Role of Dietary Habits in the Pathogenesis and Development of Inflammatory Bowel Disease: A Narrative Review.

Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), is a chronic immune-mediated disease. The incidence of IBD is influenced by various genetic and environmental factors, with dietary habits gaining significant scientific interest. While the role of diet in the pathogenesis and development of IBD is still debated, recent studies have demonstrated its potential impact.

Unraveling the impact of the p.R107L mutation on the structure and function of human αB-Crystallin: Implications for cataract formation.

To date, several pathogenic mutations have been identified in the primary structure of human α-Crystallin, frequently involving the substitution of arginine with a different amino acid. These mutations can lead to the incidence of cataracts and myopathy. Recently, an important cataract-associated mutation has been reported in the functional α-Crystallin domain (ACD) of human αB-Crystallin protein, where arginine 107 (R107) is replaced by a leucine.

Hybrid DNA/RNA nanostructures with 2'-5' linkages.

Nucleic acid nanostructures with different chemical compositions have shown utility in biological applications as they provide additional assembly parameters and enhanced stability. The naturally occurring 2'-5' linkage in RNA is thought to be a prebiotic analogue and has potential use in antisense therapeutics. Here, we report the first instance of DNA/RNA motifs containing 2'-5' linkages.

Base-pair conformational switch modulates miR-34a targeting of Sirt1 mRNA.

MicroRNAs (miRNAs) regulate the levels of translation of messenger RNAs (mRNAs). At present, the major parameter that can explain the selection of the target mRNA and the efficiency of translation repression is the base pairing between the 'seed' region of the miRNA and its counterpart mRNA. Here we use R relaxation-dispersion nuclear magnetic resonance and molecular simulations to reveal a dynamic switch-based on the rearrangement of a single base pair in the miRNA-mRNA duplex-that elongates a weak five-base-pair seed to a complete seven-base-pair seed.

A two-dimensional replica-exchange molecular dynamics method for simulating RNA folding using sparse experimental restraints.

We present a 2D replica exchange protocol incorporating secondary structure information to dramatically improve 3D RNA folding using molecular dynamics simulations. We show that incorporating base-pairing restraints into all-atom, explicit solvent simulations enables the accurate recapitulation of the global tertiary fold for 4 representative RNAs ranging in length from 24 to 68 nt. This method can potentially utilize base-pairing information from a wide variety of experimental inputs to predict complex RNA tertiary folds including pseudoknots, multi-loop junctions, and non-canonical interactions.

Partition, sorption and structure activity relation study of dialkoxybenzenes that modulate insect behavior.

Some dialkoxybenzenes are promising new insect control agents. These compounds mimic naturally occurring odorants that modulate insect behavior. Before applying these compounds, however, their persistence and biodegradability at the application site and in the environment should be understood.

Biodegradation of 1-allyloxy-4-propoxybenzene by selected strains of Pseudomonas putida.

Dialkoxybenzenes constitute a class of organic compounds with anti feeding and oviposition effects on the cabbage looper, Trichoplusia ni. Among them, 1-allyloxy-4-propoxybenzene has the highest feeding deterrence activity and potential for development as commercial insect control agent. To develop this compound, its fate in the environment needs to be studied.
