Enhancing therapeutic effects and tracking of adipose tissue-derived mesenchymal stem cells for liver injury using bioorthogonal click chemistry.

Adipose tissue-derived mesenchymal stem cell (ADSC)-based therapy is attractive for liver diseases, but the long-term therapeutic outcome is still far from satisfaction due to the low hepatic engraftment efficiency of ADSC transplantation. Herein, we propose a strategy based on liver sinusoidal endothelial cell (LSEC)-targeting peptide modification and near infrared (NIR) fluorescent probe labeling for enhancing LSEC-barrier-migration ability and in vivo tracking of ADSCs in a liver injury mouse model. RLTRKRGLK (RK), a LSEC-targeted peptide, and indocyanine green (ICG), a FDA approved infrared fluorescent dye, were simultaneously modified on the ADSC surface via a bioorthogonal click reaction.

Gene editing the BmNPV inhibitor of apoptosis protein 2 (iap2) as an antiviral strategy in transgenic silkworm.

Apoptosis is a cellular defense mechanism used for the elimination of host cells infected by viruses. Viruses have evolved corresponding inhibitors of apoptosis genes to promote their replication. Anti-apoptosis-related genes, involved in baculovirus proliferation, have been proposed but it is unclear whether these genes can be manipulated in gene therapy.

Prevalence of β-Lactam Drug-Resistance Genes in Contaminating Ready-to-Eat Lettuce.

Thirty-four isolates from 91 ready-to-eat lettuce packages, obtained from local supermarkets in Northern California, were genotyped by multilocus sequence typing, tested for susceptibility to antimicrobial agents, and screened for β-lactamase genes. We found 15 distinct sequence types (STs). Six of these genotypes (ST1198, ST2625, ST2432, ST2819, ST4600, and ST5143) have been reported as pathogens found in human samples.

We screened 429 unrelated patients with genetically unassigned CADASIL-like syndrome for mitochondrial DNA m.

The Composition and Function of Pigeon Milk Microbiota Transmitted From Parent Pigeons to Squabs.

Mammalian neonates obtain antibodies, nutrients, and microbiota from breast milk that help them resist the complex growth environment. Similar to mammals' lactation behavior for their offspring, parent pigeons regurgitate pigeon milk (PM) from their crops to feed the squabs. Whether pigeon milk is as valuable as mammalian milk is not clear, especially in terms of microbiota.

Assessment of Camouflage Effectiveness Based on Perceived Color Difference and Gradient Magnitude.

We propose a new model to assess the effectiveness of camouflage in terms of perceived color difference and gradient magnitude. The "image color similarity index" (ICSI) and gradient magnitude similarity deviation (GMSD) were employed to analyze color and texture differences, respectively, between background and camouflage images. Information entropy theory was used to calculate weights for each metric, yielding an overall camouflage effectiveness metric.

Catalytic Asymmetric Three-Component Reaction of 2-Alkynylbenzaldehydes, Amines, and Dimethylphosphonate.

An efficient enantioselective synthesis of cyclic α-aminophosphonates via multicomponent reactions of 2-alkynylbenzaldehydes, amines, and dimethylphosphonate has been developed with the use of a chiral silver spirocyclic phosphate as the catalyst. This protocol provides straightforward access to a series of chiral C1-phosphonylated 1,2-dihydroisoquinoline derivatives with high yields (up to 99%) and high enantioselectivities (up to 94% ee) for a broad substrate scope. The products could be further transformed into densely functionalized compounds and corresponding α-aminophosphonic acids.
