Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Indirect measurement of pasture mass and pasture growth rate on sheep and beef pastures
This study aimed to develop calibrations for the measurement of pasture mass and pasture growth rate on sheep and beef pastures. Herbage within quadrats (0.12-0.2 m2) was measured with either an electronic rising plate meter (RPM) (n=2279), capacitance pasture meter (CPM) (n=693) or pasture ruler (n=2528) for the development of linear and curvilinear ...

Small RNA pathways in mammalian oocytes
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Dual native G‐quadruplex folding is associated with chromatin looping at the MYC locus
BG4‐detectable G‐quadruplex (G4) in HaCaT and NHEK keratinocytes identified folded and unfolded G4s enriched at promoters/TSSs and active enhancers, whereas unfolded G4s also overlapped weak/poised enhancers. At MYC–PVT1, 3C‐qPCR detected enhancer–promoter looping only when G4s were simultaneously folded at both regulatory elements under native ...

Agronomic Behavior of Cenchrus purpureus Varieties Tolerant to Salinity
A study was made at the Experimental Station of Pastures and Forages, at the Jorge Dimitrov Agricultural Research Institute to determine the effect of cutting age (60, 90, 120 days), and cultivar (CT-500 and CT-115) of new varieties of Cenchrus purpureus

Epigenetic reprogramming in hematopoietic stem and progenitor cells (HSPCs) and downstream myeloid cells, mediated by H3.3 downregulation and endogenous retroelement (ERE) overexpression, contributes to the progression of multiple sclerosis (MS). ABSTRACT Background Skewed myelopoiesis in the bone marrow has been identified as a key driver of multiple ...

BENEFITS OF JOINT MANAGEMENT OF GREEN MANURE AND MYCORRHIZAL INOCULANTS IN CROP PRODUCTION
Background. Nutrient supply is a decisive component of agricultural systems, but in Cuba only 25 % of cultivated areas can be fertilized, influencing their productivity negatively.

Cracking the Code: Genotype–Phenotype Correlation Models in Sarcoglycanopathies
ABSTRACT Objective Sarcoglycanopathies are among the most severe limb‐girdle muscular dystrophies (LGMD), though milder presentations have been described. These diseases are primarily caused by missense variants, but the limited predictability of their effect on protein maturation, complex formation, and transport has hindered reliable genotype ...
