Investigation of selection signatures of dairy goats using whole-genome sequencing data.

Dairy goats, a livestock species with a long history of milk production, are essential for the economic advancement of nations, particularly in regions experiencing growth. In this study, we gathered whole-genome resequencing data of 58 goats, including 34 dairy goats and 24 wild goats (Bezoar), to explore the selection signatures linked to milk production traits using ROH (Runs of homozygosity), CLR (composite likelihood ratio), Fst (Fixation index), XP-EHH (Ex-tended haplotype homozygosity across populations) and XP-CLR(Cross-population composite likelihood ratio test) methods. Analysis of five tests of selection signatures for dairy goats revealed a total of 210 genes, with 24 genes consistently identified in at least two approaches.

Mining and analysis of key genes related to rice seed longevity in NJ9108 based on transcriptomics.

Longevity changes in seed directly affect the germination rate, seedling morphology, and storage time. Therefore, the identification of seed longevity genes has significant value for cultivating seeds that are storage-resistant and have long lifespan.

Promotion of microplastic degradation on the conjugative transfer of antibiotic resistance genes in the gut of macrobenthic invertebrates.

Due to the natural salt solubility of proteins as emulsifiers, a large amount of salt is required to fill the emulsion system to facilitate the completion and stability of the emulsion emulsification process. High salt diets and edible products have been rejected and gradually replaced by health products dominated by low salt concepts. However, low salt conditions can make it difficult for emulsion systems to form or collapse.

Kinetic Resolution of Racemic Radicals in Asymmetric Photoredox Minisci Reactions with Azaarenes for Precise Construction of Two Non-adjacent Stereocenters.

Despite the significant potential of photocatalysis as a robust synthetic tool, the high reactivity of radicals often presents challenges in achieving optimal chemoselectivity. In this study, we demonstrate that this inherent limitation can be strategically harnessed for asymmetric photoredox catalysis. By utilizing a chiral catalyst to facilitate kinetic resolution between the two enantiomers of racemic radical intermediates, one enantiomer selectively undergoes the desired transformation, while noncatalytic side reactions deplete the other enantiomer.

Unraveling Compressive Strain and Oxygen Vacancy Effect of Iridium Oxide for Proton-Exchange Membrane Water Electrolyzers.

Iridium-based electrocatalysts are commonly regarded as the sole stable operating acidic oxygen evolution reaction (OER) catalysts in proton-exchange membrane water electrolysis (PEMWE), but the linear scaling relationship (LSR) of multiple reaction intermediates binding inhibits the enhancement of its activity. Herein, the compressive strain and oxygen vacancy effect exists in iridium dioxide (IrO)-based catalyst by a doping engineering strategy for efficient acidic OER activity. In situ synchrotron characterizations elucidate that compressive strain can enhance Ir─O covalency and reduce the Ir─Ir bond distance, and oxygen vacancy (O) as an electronic regulator causes rapid adsorption of water molecules on the Ir and adjacent Ov (Ir─O) pair site to be coupled directly into O─O intermediates.

The results indicate that higher temperatures enhance the CO permeability, while an appropriate amount of water improves separation selectivity. The effects of DES and PEGIL (PEG-modified ionic liquid) solvents differ due to their distinct molecular structures.

Ultrahigh antipsychotics selective accumulation and efficient photocatalytic degradation using a novel 2D BiOIO-based molecularly imprinted photocatalyst.

Adsorption-assisted photocatalytic degradation of pollutants is an effective method to improve degradation efficiency. However, most adsorptive photocatalysts are not selective and cannot efficiently remove low-concentration targets in complex systems, which limit their practical application. Therefore, a novel molecularly imprinted photocatalyst (MI-BiOIO) with high selectivity and adsorption capacity was prepared using two-dimensional BiOIO nanosheet as the matrix.

Quality control of mitochondrial nucleoids.

Mitochondrial nucleoids, organized complexes that house and protect mitochondrial DNA (mtDNA), are normally confined within the mitochondrial double-membrane system. Under cellular stress conditions, particularly oxidative and inflammatory stress, these nucleoids can undergo structural alterations that lead to their aberrant release into the cytoplasm. This mislocalization of nucleoid components, especially mtDNA, can trigger inflammatory responses and cell death pathways, highlighting the critical importance of nucleoid quality control mechanisms.
