Sake is a Japanese alcoholic beverage produced by fermenting steamed rice and (a culture of on steamed rice) with sake yeast, a strain of Sake yeast strains are important for maintaining product quality and process efficiency. In this study, a strain from Muramatsu Park, Gosen City, Niigata Prefecture was isolated using a loop-mediated isothermal amplification (LAMP) assay. The yeast strain was cultured using the mass spore-cell/cell-cell mating method with a sake yeast haploid.

Article Synopsis
  • A proposed model aims to assess the risk of sudden water influx during tunnel construction in the karst region of southwest China, combining game theory with uncertainty measure theory.
  • The model identifies eight risk indicators related to rock solubility, geological structure, surface catchment, and hydrogeological factors, with subjective and objective weights calculated using various methods.
  • Tested on the Yanjin Tunnel of the Chongqing-Kunming High-speed Railway, the model showed consistent results with actual water inflow data, proving its effectiveness as a tool for evaluating water surge risks in karst tunnels.

Aim: Recent evidence suggests that acute liver failure (ALF) in some patients may reflect a dysregulated immune response, and that corticosteroids improve survival of the native liver in ALF patients with high serum alanine aminotransferase levels, which are an indication of liver inflammation. However, it is unclear whether steroids are effective for pediatric acute liver failure (PALF). The aim of this retrospective case-control study is to examine whether steroid therapy for PALF accompanied by immune activation improves the survival of native liver and to identify factors that predict responses to steroid treatment.

Emphysematous osteomyelitis (EO) is a rare and potentially fatal disease that often occurs in patients with underlying conditions, most commonly diabetes mellitus. Herein, we report a case of a 62-year-old man who presented with fever, tachycardia, and hypotension 112 days after liver transplantation. Blood tests revealed an increased inflammatory response.

Introduction Fan therapy has gained attention as a non-pharmacological treatment for alleviating dyspnea in patients receiving palliative care and in those with chronic progressive diseases. However, the effectiveness of fan therapy for dyspnea in critically ill patients in intensive care units (ICUs) remains unclear. This study aimed to investigate the efficacy and safety of fan therapy for lung transplant patients in the ICU.

Single-chain Fv (scFv) is a recombinant small antibody in which a polypeptide linker connects the variable regions of the light chain (VL) and the heavy chain (VH). The practical use of scFv, however, has been prevented by its tendency to aggregate due to interchain VL-VH interactions. We recently developed a cyclic scFv whose N-terminus and C-terminus were connected by protein ligation techniques.

Background: Long non-coding RNA (lncRNA) plays a crucial role in various biological processes, and mutations or imbalances of lncRNAs can lead to several diseases, including cancer, Prader-Willi syndrome, autism, Alzheimer's disease, cartilage-hair hypoplasia, and hearing loss. Understanding lncRNA-protein interactions (LPIs) is vital for elucidating basic cellular processes, human diseases, viral replication, transcription, and plant pathogen resistance. Despite the development of several LPI calculation methods, predicting LPI remains challenging, with the selection of variables and deep learning structure being the focus of LPI research.

Background: Eisenmenger syndrome (ES) is characterized by severe and irreversible pulmonary hypertension stemming from an uncorrected intracardiac shunt of significant size. The imbalance between systemic and pulmonary artery pressures predisposes patients with ES to the risk of cardiac arrest. Remimazolam has caused less circulatory depression, which may be advantageous for ES.

Article Synopsis
  • Nodular regenerative hyperplasia (NRH) is a rare liver disease that appears as small lumps in the liver and is linked to various health problems but can be hard to diagnose correctly.
  • A 49-year-old man found tumors in his liver during a check-up, but he didn't have any symptoms; doctors first thought it was a type of liver cancer.
  • After surgery to remove the tumors, tests showed they were actually non-cancerous lumps that looked like NRH, making it a complicated case for doctors.

Article Synopsis
  • The study examined chest CT findings in patients with severe acute respiratory distress syndrome (ARDS) undergoing veno-venous extracorporeal membrane oxygenation (V-V ECMO) across 24 hospitals in Japan.
  • Among 582 patients who had chest CT at V-V ECMO initiation, traction bronchiectasis and subcutaneous emphysema were associated with increased 90-day mortality, while patients with traction bronchiectasis were less likely to be successfully liberated from ECMO.
  • The findings suggest that certain chest CT features can provide important prognostic information and may be useful for predicting outcomes in severe ARDS patients on V-V ECMO.

Aim: This study was conducted to investigate the relationship between the hospitalizations and backgrounds of patients with coronavirus disease 2019 to identify specific risk factors.

Methods: This retrospective study used health observation records to analyze the relationship between certain risk factors and the subsequent hospitalization of 321 patients who were discharged from a residential care facility between January 16 and February 8, 2021. The usefulness of a hospitalization prediction score, created based on the presence of comorbidities and sex, was examined.

Remdesivir plays a key role in the treatment of coronavirus disease in 2019 (COVID-19). Haemodialysis is sometimes required for hospitalised patients with COVID-19, and patients undergoing haemodialysis are at an increased risk of severe COVID-19. In the present study, we report the serum concentrations of GS-441524, the active metabolite of remdesivir, in four patients undergoing continuous renal replacement therapy (CRRT).

In Japan, only single-unit cord blood transplantations (CBTs) are typically performed, and their number has increased over the last 23 years, with ongoing improvement in results. In most cases, CBTs with multiple HLA mismatches are used, owing to a low HLA barrier, and lower engraftment rate is a problem that must be overcome. Here, as part of an effort to improve guidelines for the selection and processing of CB units for transplantation, we sought to assess the present status of CBT in Japan and to elucidate factors contributing to the favorable outcomes, focusing in particular on selection by cell components of CB unit and HLA allele matching.

Functional dipeptides carnosine and anserine are abundant in muscle. We determined the effect of short-term dietary histidine (His) content on muscle carnosine and anserine contents and meat quality of broilers. Three groups of 28-day-old female broilers were fed diets with His contents of 67%, 100%, or 150% of requirement for 10 days before market (His contents 0.

This experiment investigated the sex responses of heat stress (HS) and subsequent recovery on growth performance, serum metabolic parameters, and redox status. Two hundred 38-day-old broilers were arranged in a completely randomized design with a 2 × 2 (temperatures and sexes) factorial arrangement in five replicates. Broilers were raised at 24 ± 1 °C or 32 ± 1 °C for 3 days and returned to 24 °C for 2 days.

Purpose: Small gastrointestinal stromal tumors (GISTs) can generally have nonspecific CT findings similar to those with benign submucosal tumors of the stomach. The purpose of this study was to explore the potential dual-layer dual-energy CT (dlDECT) parameters to differentiate small-sized (≤ 4 cm) GISTs from leiomyomas of the stomach.

Materials And Methods: This retrospective study included 26 SMTs ≤ 4 cm in diameter with pathological confirmation of either GIST (n = 17) or leiomyoma (n = 9) from May 2018 to January 2022.
