The sake yeast allele contributes to the regulation of the tetrahydrofolate content in the folate synthetic pathway in sake yeast strains.

To elucidate the mechanism underlying tetrahydrofolate (THF) accumulation in sake yeast strains compared with that in laboratory yeast strains, we performed a quantitative trait locus (QTL) analysis. The results revealed that the sake yeast allele contributes to an increase in the ratio of THF to the total folate content in sake yeast.

Clinical prediction rule for neurological sequelae due to acute encephalopathy: a medical community-based validation study in Harima, Japan.

Objectives: This study aimed to verify the screening performance of our clinical prediction rule for neurological sequelae due to acute encephalopathy (NSAE-CPR), which previously identified the following three variables as predictive of poor outcomes: (1) refractory status epilepticus; (2) consciousness disturbance and/or hemiplegia at 6 hours from onset and (3) aspartate aminotransferase >90 IU/L within 6 hours of onset.

Design: Medical community-based multicentre retrospective cohort study.

Setting: Six regional hospitals in Harima and one tertiary centre in Kobe, Japan, from 2008 to 2012.

Sake yeast YHR032W/ERC1 haplotype contributes to high S-adenosylmethionine accumulation in sake yeast strains.

Sake yeasts are ideally suited for sake making, producing higher levels of ethanol, proliferating at lower temperatures, and producing greater levels of various aromatic components and nutrients than laboratory yeasts. To elucidate the mechanism underlying S-adenosylmethionine (SAM) accumulation in sake yeast strains compared with that in laboratory yeast strains, we performed quantitative trait locus (QTL) analysis and identified a significant QTL on chromosome VIII. Of the 165 genes mapped at 49.

Development of an enzyme-linked immunosorbent assay for serological diagnosis of tick-borne encephalitis using subviral particles.

The similarity of symptoms produced by tick-borne encephalitis (TBE) and Japanese encephalitis (JE) and the high degree of cross-reactivity between TBE and JE viruses by serological tests make the development of a differential diagnostic test a priority. In this study, recombinant prM/E proteins of TBE virus strain Oshima 5-10 expressed in mammalian cells resulted in the release of subviral particles (SPs) into the culture medium. Using the SPs as antigens, enzyme-linked immunosorbent assay (ELISA) systems were developed to detect TBE virus-specific IgM and IgG antibodies, designated SP-IgG and SP-IgM ELISAs, respectively.
