Micro-injection Molded Droplet Generation System for Digital PCR Application.

Sensitive, effective, and quantitative analysis of infectious pathogens is an important task for the prevention of human health threats. Herein, we present an advanced approach to producing gene-encapsulated microdroplets for quantitative analysis using a micropatterned metal mold and injection molding technique with an automatically operated system. An injection molded microdroplet generation device was successfully fabricated with a minimum channel width of 30 μm and optimized to produce 100 μm diameter droplets.

Prediction of crime occurrence from multi-modal data using deep learning.

In recent years, various studies have been conducted on the prediction of crime occurrences. This predictive capability is intended to assist in crime prevention by facilitating effective implementation of police patrols. Previous studies have used data from multiple domains such as demographics, economics, and education.

Strain-dependent response to Cu(2+) in the expression of laccase in Pycnoporus coccineus.

The effects of Cu(2+) on the activity and expression of laccase were investigated in seven different strains of Pycnoporus coccineus collected from different regions in Korea. Cu(2+) was toxic to mycelial growth at concentrations greater than 0.5 mM CuSO4 and showed complete growth inhibition at 1 mM in the liquid culture.

Cloning and Molecular Characterization of β-1,3-Glucan Synthase from Sparassis crispa.

A β-glucan synthase gene was isolated from the genomic DNA of polypore mushroom Sparassis crispa, which reportedly produces unusually high amount of soluble β-1,3-glucan (β-glucan). Sequencing and subsequent open reading frame analysis of the isolated gene revealed that the gene (5,502 bp) consisted of 10 exons separated by nine introns. The predicted mRNA encoded a β-glucan synthase protein, consisting of 1,576 amino acid residues.

Generation and Evaluation of High β-Glucan Producing Mutant Strains of Sparassis crispa.

A chemical mutagenesis technique was employed for development of mutant strains of Sparassis crispa targeting the shortened cultivation time and the high β-glucan content. The homogenized mycelial fragments of S. crispa IUM4010 strain were treated with 0.

Breeding of new strains of mushroom by basidiospore chemical mutagenesis.

Chemical mutagenesis of basidiospores of Hypsizygus marmoreus generated new mushroom strains. The basidospores were treated with methanesulfonate methylester, an alkylating agent, to yield 400 mutant monokaryotic mycelia. Twenty fast-growing mycelia were selected and mated each other by hyphal fusion.
