Discovery of 15-deoxynaphthomycins activating the antioxidant NRF2-ARE pathway from Streptomyces sp. N50 via genome mining, global regulator introduction, and molecular networking.

Genome mining is a promising avenue for expanding the repertoire of microbial natural products, which are important for drug development. This approach involves predicting genetically encoded small molecules by examining bacterial genomes via accumulated knowledge of microbial biosynthesis. However, it is also important that the microbes produce the predicted molecule in practice.

Therapeutic potential of a systemically applied humanized monoclonal antibody targeting Toll‑like receptor 2 in atopic‑dermatitis‑like skin lesions in a mouse model.

Atopic dermatitis (AD) is a prevalent, persistent inflammatory skin disorder distinguished by pruritic and irritated skin. Toll-like receptors (TLRs) are specialized receptors that recognize specific patterns associated with pathogens and tissue damage, triggering an innate immune response that protects the host from invading pathogens. Previously, it was demonstrated that intradermal injection of the humanized anti-TLR2 monoclonal antibody (Ab) Tomaralimab effectively relieved AD-like skin inflammation in BALB/c mouse models exposed to house dust mite extracts.

Recurrence-free survival after hepatectomy using propofol-based total intravenous anaesthesia and sevoflurane-based inhalational anaesthesia: a randomised controlled study.

Background: While evidence from preclinical and observational cohort studies have suggested potential disparities in tumour behaviour associated with the choice of intra-operative anaesthetics, clinical evidence of tumour recurrence and metastasis remains inconclusive. We aimed to compare the impact of intra-operative anaesthesia on oncologic outcomes following hepatectomy for hepatocellular carcinoma.

Methods: Adult patients scheduled for elective hepatectomy for hepatocellular carcinoma were assigned randomly (1:1) to either propofol-based total intravenous anaesthesia or sevoflurane-based inhalational anaesthesia.

Relationship between the Geriatric Nutrition Risk Index and the prognosis of severe coronavirus disease 2019 in Korea.

Background: Malnutrition exacerbates the prognosis of various diseases; however, its specific impact on severe coronavirus disease (COVID-19) outcomes remains underexplored.

Methods: This multicenter study in Korea assessed the nutritional status of 1,088 adults with severe COVID-19 using the Geriatric Nutritional Risk Index (GNRI) based on serum albumin levels and body weight. The patients were divided into the GNRI>98 (no-risk) and GNRI≤98 (risk) groups.

Therapeutic role of aripiprazole in cartilage defects explored through a drug repurposing approach.

Articular cartilage has a limited regenerative capacity, resulting in poor spontaneous healing of damaged tissue. Despite various scientific efforts to enhance cartilage repair, no single method has yielded satisfactory results. With rising drug development costs, drug repositioning has emerged as a viable alternative.
