20-Hydroxyeicosatetraenoic acid (20-HETE) is a lipid mediator and one of the major arachidonic acid metabolites whose formation is mainly catalyzed by the enzymes cytochrome P450 (CYP) 4F2 and CYP4A11. Several studies have suggested that 20-HETE is involved in the pathogenesis of renal diseases, including diabetic nephropathy and autosomal dominant polycystic kidney disease, and we previously reported compound 1 as a dual inhibitor of CYP4A11/4F2 with therapeutic potential against renal fibrosis. Subsequent studies revealed that compound 1, the dual CYP4A11/4F2 inhibitor, however, exhibited low selectivity over another CYP4F subtype, CYP4F22, which catalyzes ω-hydroxylation of ultra-long-chain fatty acids (ULCFAs); ULCFAs are important for the formation of acylceramides, which play a role in skin barrier formation.

Prompt gammas imaging (PGI) is a promising method for observing a beam's shape and estimating the range of the beam from outside a subject. However 2-dimensional images of prompt gammas (PGs) during irradiation of protons were still difficult to measure. To achieve PGI, we developed a new gamma camera and imaged PGs while irradiating a phantom by proton beams.

Article Synopsis
  • Researchers conducted a study to explore the connection between thyroid autoantibodies (Tabs) and the clinical profiles of young patients (ages 3-29) with thyroid nodules, using data from 3,018 participants in the Fukushima Health Management Survey.
  • The study discovered that Tabs were found in 13.9% of participants, with higher rates in females, those with diffuse goiter, and those diagnosed with papillary thyroid carcinoma.
  • Findings indicate that Tab positivity is linked to larger thyroid sizes, the presence of diffuse goiter and papillary thyroid carcinoma, and high TSH levels, suggesting that testing for Tabs could enhance assessment methods for thyroid function and cancer detection in younger patients with nodules.

Background: Approximately 80% of non-communicable diseases (NCDs) have been reported in low- and middle-income countries (LMICs). However, studies on the usefulness of educational interventions run by non-healthcare workers in combating NCDs in resource-limited areas in rural parts of LMICs are limited. This study aimed to identify the effectiveness of a community-based simple educational program run by non-healthcare trained staff for several outcomes associated with NCDs in a resource-limited area.

Differentiating between idiopathic interstitial pneumonia (IIP) and secondary interstitial pneumonia, particularly connective tissue disease-associated interstitial lung disease (CTD-ILD), can be challenging histopathologically, and there may be discrepancies among pathologists. While surgical lung biopsy has traditionally been considered the gold standard for diagnosing interstitial pneumonia, the usefulness of transbronchial lung cryobiopsy (TBLC) has been reported. If TBLC could effectively distinguish between primary and secondary diseases, it would provide a less invasive option for patients.

  • Isoamyl alcohol is important for the ginjo aroma in sake and is produced via a biosynthesis pathway in yeasts involving the THI3 gene, which affects its production.
  • Disruption of the THI3 gene (Δthi3) results in decreased isoamyl alcohol production, especially under low nitrogen and low thiamine conditions.
  • The study found that the decrease in isoamyl alcohol in Δthi3 strains is linked to reduced levels of thiamine and thiamine diphosphate (TPP), a vital cofactor for enzyme activity, suggesting that THI3 is crucial for maintaining TPP levels necessary for isoamyl alcohol production.
