The cold-tolerant yeast is industrially useful for lager fermentation, high-quality wine, and frozen dough production. Cheongdo is a recent isolate from frozen peach samples which has a good fermentation performance at low temperatures and desirable flavor profiles. Here, phenotype microarray was used to investigate industrial potentials of Cheongdo using 192 carbon sources. Compared to commercial wine yeast EC1118, Cheongdo showed significantly different growth rates on 34 substrates. The principal component analysis of the results highlighted that the better growth of Cheongdo on galactose than on EC1118 was the most significant difference between the two strains. The intact gene and the galactose fermentation performance at a low temperatures suggested that Cheongdo is a promising host for industrial fermentation rich in galactose, such as lactose and agarose.

A male in his 20s presented with episodic headache and subsequently developed episodic unilateral weakness, dysphasia and encephalopathy. These paroxysmal episodes persisted over time with the development of background cognitive impairment and neuropsychiatric symptoms. MRI surveillance demonstrated progressive T2 hyperintensity with focal cortical oedema correlating to symptoms observed during clinical episodes.

Assessing the composition of immune pathways in neurodegenerative diseases can contribute to precision medicine. Using publicly available transcriptomic data, we sought to elucidate transcriptional networks pertinent to inflammatory pathways across brain regions and peripheral blood in AD/mild cognitive impairment (MCI) and peripheral blood in Parkinson's disease (PD).

Background: While there are numerous genome-wide association studies (GWAS) assessing the genetic basis of Alzheimer's disease (AD), there are far fewer studies examining genetic factors for cognitive and global resilience to AD neuropathology. By focusing on a gene-level rather than a single-variant basis, transcriptome-wide association studies (TWAS) have increased statistical power relative to GWAS and can assess the role of genetically regulated gene expression in AD resilience. We leveraged the largest available cis-eQTL meta-analysis summary statistics from brain tissue (MetaBrain Brain-Cortex; N = 2,547) and whole blood (eQTLGen; N = 31,684) and applied them to the largest cognitive and global resilience to AD neuropathology summary statistics from Dumitrescu et al.

Background: Structural variation (SV), defined as balanced and unbalanced chromosomal rearrangements >1 kb, is a major contributor to germline and neoplastic disease. Large variants have historically been evaluated by chromosome analysis and now are commonly recognized by chromosomal microarray analysis (CMA). The increasing application of genome sequencing (GS) in the clinic and the relatively high incidence of chromosomal abnormalities in sick newborns and children highlights the need for accurate SV interpretation and reporting.

is an important bacterial pathogen implicated in infections such as mastitis, metritis, pneumonia, and liver abscesses in both domestic and wild animals, as well as endocarditis and prosthetic joint infections in humans. Understanding the genomic and metabolic features that enable to colonize different anatomical sites within a host and its inter-kingdom transmission and survival is important for the effective control of this pathogen. We employed whole-genome sequencing, phenotype microarrays, and antimicrobial susceptibility testing to identify genomic, metabolic and phenotypic features, and antimicrobial resistance (AMR) genes in recovered from different livestock, companion, and wildlife animals.
