Drug resistance in Plasmodium falciparum parasites is associated with the single nucleotide polymorphism (SNP) exo-E415G, which considered as a marker to reduce susceptibility artimisinin and leads treatment failure. This study aims establish procedure based on tetra-primer ARMS PCR technique detect SNP exo-E415G malaria patients who experienced failure artemisinin. DNA sample from P. 3D7 isola...
A strategy for exo and enantioselective 1,3-dipolar cycloaddition of azomethine imines to 2-acryloyl-3-pyrazolidinone is described. The corresponding cycloadducts are isolated with high diastereoselectivities (up to >96:4 exo/endo) and enantioselectivities (up to 98% ee).
The cycloisomerisation of simple keto-alkynes proceeds at room temperature under the mild conditions of gold catalysis. Bicyclic fused and spiro compounds can be obtained by overall 5-exo and 6-exo carbon-carbon bond-forming cyclisations.
Increasing evidence suggests that exosomes are involved in retinal cell degeneration, including their insufficient release; hence, they have become important indicators of retinopathies. The exosomal microRNA (miRNA), particular, play roles regulating ocular and functions, photoreceptor maturation, maintenance, visual function. Here, we generated organoids (ROs) from human induced pluripotent s...
At synapses in the mammalian brain, continuous information transfer requires the long-term maintenance of homeostatic coupling between exo- and endocytosis of synaptic vesicles. Because classical endocytosis is orders of magnitude slower than the millisecond-range exocytosis of vesicles, high frequency vesicle fusion could potentially compromise structural stability of synapses. However, the mo...
Alkaline exonuclease and single-strand DNA (ssDNA) annealing proteins (SSAPs) are key components of DNA recombination and repair systems within many prokaryotes, bacteriophages and virus-like genetic elements. The recently sequenced β-proteobacterium Laribacter hongkongensis (strain HLHK9) encodes putative homologs of alkaline exonuclease (LHK-Exo) and SSAP (LHK-Bet) proteins on its 3.17 Mb gen...
A phage lambda-based recombination system, Red, can be used for high-efficiency mutagenesis, repair, and engineering of chromosomal or episomal DNA in vivo in Escherichia coli. When long linear double-stranded DNA with short flanking homologies to their targets are used for the recombination, the lambda Exo, Beta, and Gam proteins are required. The current model is: (i) Gam inhibits the host Re...
We report here the first combined amplified fragment length polymorphism (AFLP) analysis of genomic DNA fingerprinting data and cluster analysis of the exo-polysaccharide glycosyl linkage data of 10 regionally different strains of Lentinula edodes to compare their genetic and structural similarities and differences. In addition, the monosaccharide compositions, molecular weights, glycosyl struc...
