Efficient Gene Delivery Admitted by small Metabolites Specifically Targeting Astrocytes in the Mouse Brain.

The development of efficient and targeted methods for delivering DNA in vivo has long been a major focus of research. In this study, we introduce a gene Delivery approach Admitted by small Metabolites, named gDAM, for the efficient and targeted delivery of naked DNA into astrocytes in the adult brains of mice. gDAM utilizes a straightforward combination of DNA and small metabolites, including glycine, L-proline, L-serine, L-histidine, D-alanine, Gly-Gly, and Gly-Gly-Gly, to achieve astrocyte-specific delivery of naked DNA, resulting in transient and robust gene expression in these cells.

Chlamydomonas reinhardtii polysaccharides retard rice starch retrogradation by weakening hydrogen bond strength within starch double helices.

This study investigated the effects of Chlamydomonas reinhardtii polysaccharides (CRPs) on retarding the retrogradation of japonica rice starch (JS) and glutinous rice starch (GS). Structure characterization revealed that CRPs, with an average molecular weight of 505 kDa, mainly consisted of glucose, mannose, and galactose and featured a triple-helix structure. CRPs could reduce the storage modulus increment of JS during the cooling process by interacting with amylose, thereby inhibiting gel network formation.

Targeting a cysteine proteinase inhibitor and a defensin-like protein in Litchi chinensis seed development leveraging endosperm single-nucleus transcriptome.

Seed development is one of the most important agricultural traits, determining both the crop yield and quality of fleshy fruits. A typically abortive litchi cultivar, Guiwei, exhibits heterogeneity in seed size across production areas, years, and individual trees. Previous studies have shown that 'Guiwei' seed development failure is associated with endosperm arrest and chilling conditions.

Impact of short-term soil disturbance on cadmium remobilization and associated risk in vulnerable regions.

A comprehensive understanding of cadmium (Cd) migration in soils near contaminated hotspots is crucial for optimizing remediation efforts and ensuring crop health. This study investigates agricultural soils from four sites in mining and sewage-irrigation areas, assessing the impact of inorganic and organic fertilizer application on soil Cd remobilization.

Matrine disturbs the eimeria necatrix-induced loop of tuft cell-intestinal stem cell-goblet cell by inactivating IL-13/JAK2/STAT3 signaling.

As sensors in the gut, tuft cells integrate a complex array of luminal signals to regulate the differentiation fate of intestinal stem cells (ISCs), which trigger a loop of tuft cell-ISC-goblet cell after parasitic infection. As a plant-derived alkaloid, Matrine plays a prominent role for standardizing ISC functions in Eimeria necatrix (EN)-exposed chicks. In this study, we investigated the modulation effects of Matrine on the specific intestinal epithelial cell loop in EN-exposed chicks in vivo and intestinal organoids (IOs) ex vivo.

LC-MS/MS Analyzing Praziquantel and 4-Hydroxypraziquantel Enantiomers in Black Goat Plasma and Mechanism of Stereoselective Pharmacokinetics.

Praziquantel (PZQ) is the most effective treatment for schistosomiasis, commonly administered as a racemic mixture of the two enantiomers. Despite many reports on the pharmacokinetics of PZQ, the stereoselective pharmacokinetics of PZQ and its major metabolite 4-hydroxypraziquantel (4-OH-PZQ) remain poorly understood in goats. In this study, the chiral LC-MS/MS method was further optimized for separating and quantifying PZQ, trans-4-OH-PZQ, and cis-4-OH-PZQ and their enantiomers and then applied for the molecular pharmacokinetics of three analytes in black goat plasma.
