Discovery of Spirosnuolides A-D, Type I/III Hybrid Polyketide Spiro-Macrolides for a Chemotherapeutic Lead against Lung Cancer.

Four new macrolides, spirosnuolides A-D (-, respectively), were discovered from the termite nest-derived sp. INHA29. Spirosnuolides A-D are 18-membered macrolides sharing an embedded [6,6]-spiroketal functionality inside the macrocycle and are conjugated with structurally uncommon side chains featuring cyclopentenone, 1,4-benzoquinone, hydroxyfuroic acid, or butenolide moieties.

High-Throughput Screening of 3-Dimensional Co-culture Hair Follicle Mimetic Tissue with an Enhanced Extracellular Matrix for the Screening of Hair Growth-Promoting Compounds.

Hair follicle cells reside within a complex extracellular matrix (ECM) environment in vivo, where physical and chemical cues regulate their behavior. The ECM is crucial for hair follicle development and regeneration, particularly through epithelial-mesenchymal interactions. Current in vitro models often fail to replicate this complexity, leading to inconsistencies in evaluating hair loss treatments.

Comparison of different group-level templates in gradient-based multimodal connectivity analysis.

The study of large-scale brain connectivity is increasingly adopting unsupervised approaches that derive low-dimensional spatial representations from high-dimensional connectomes, referred to as gradient analysis. When translating this approach to study interindividual variations in connectivity, one technical issue pertains to the selection of an appropriate group-level template to which individual gradients are aligned. Here, we compared different group-level template construction strategies using functional and structural connectome data from neurotypical controls and individuals with autism spectrum disorder (ASD) to identify between-group differences.

Efficacy and safety of rebamipide/nizatidine in patients with erosive gastritis: A randomized, multicenter, phase 4 study.

Background: For the treatment of gastritis, rebamipide, a mucoprotective agent, and nizatidine, a gastric acid suppressant, are commonly employed individually.

Aim: To compare the efficacy of Mucotra SR (rebamipide 150 mg) and Axid (nizatidine 150 mg) combination therapy with the sole administration of Axid in managing erosive gastritis.

Methods: A total of 260 patients diagnosed with endoscopically confirmed erosive gastritis were enrolled in this open-label, multicenter, randomized, phase 4 clinical trial, allocating them into two groups: Rebamipide/nizatidine combination twice daily nizatidine twice daily for 2 weeks.

Prognostic Implications of the Bethesda System in Fine-Needle Aspiration for Follicular Thyroid Carcinoma.

Context.—: Fine-needle aspiration is an effective tool for sampling thyroid nodules; its results are classified according to the Bethesda System for Reporting Thyroid Cytopathology (BSRTC), whose categories define malignancy risks.
