Comprehensive Evaluation of Fructus Tsaoko, Seeds of Tsaoko Fructus and Ginger Made Seeds of Tsaoko Fructus Based on Drug‐Like Compounds and Aroma Analysis

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
This study mainly consists of two parts. First, after screening for drug‐like metabolites via LC–MS and GC–MS, a comprehensive evaluation model was established using a principal component analysis‐based weighted scoring method, by which the drug‐likeness ranking of three samples was determined.

Rhodium‐Catalyzed Regioselective Addition of N‐Hydroxyl Imides to Internal Alkynes

Israel Journal of Chemistry, Volume 66, Issue 3, May 2026.
An intermolecular rhodium‐catalyzed regioselective addition of N‐hydroxyl imides to internal alkynes leads to branched O‐allyl compounds, which can be readily transformed to allylic alcohols and O‐allyl hydroxylamines after deprotection. Isotopic labelling experiments suggest a plausible reaction mechanism.

Novel Laboratory Approaches in Heavy Chain Disease With Discordant Immunoglobulin Quantitation: A Case Report and Literature Review

Journal of Clinical Laboratory Analysis, Volume 40, Issue 9, May 2026.
In this study, we investigated a rare case of γ‐heavy chain disease (γ‐HCD) through an integrated laboratory approach. Routine protein analyses (serum protein electrophoresis, immunotyping, and serum/urine immunofixation) identified an IgG monoclonal component without detectable light chains.

OCTA-Based Biomarker Characterization in nAMD

2025 IEEE 6th International Conference on Image Processing, Applications and Systems (IPAS)
We aim to enhance ophthalmologists' decision-making when diagnosing the Neovascular Age-Related Macular Degeneration (nAMD). We developed three tools to analyze Optical Coherence Tomography Angiography images: (1) extracting biomarkers such as mCNV area and vessel density using image processing; (2) generating a 3D visualization of the ...

Metal‐Free Electrophilic Borylative Cyclizations of Alkynes

The Chemical Record, Volume 26, Issue 5, May 2026.
Metal‐free borylative cyclizations based on electrophilic alkyne activation by boron Lewis acids provide efficient access to borylated hetero‐ and carbocycles. Early studies using B(C6F5)3 displayed limited scope and application, whereas recent ClBcat‐ and BCl3‐based methods enable mild CB and CC/CX bond formation for the synthesis of cycles ...

Choroidal vascular hyperpermeability patterns in central serous chorioretinopathy correlate with microperimetry: CERTAIN study report 4

Acta Ophthalmologica, Volume 104, Issue 3, Page 288-295, May 2026.
Abstract Purpose This report evaluates the association of three distinct leakage patterns of choroidal vascular hyperpermeability (CVH) on indocyanine green angiography (ICGA), previously correlated with disease chronicity, with retinal sensitivity measured by microperimetry in central serous chorioretinopathy (CSC): unifocal indistinct signs of ...
