Adverse Cardiovascular Risk Profile and Increased Diurnal Salivary Cortisol in Girls With Turner Syndrome: An Exploratory Study

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Patients with Turner Syndrome (TS) and those exposed to high concentrations of glucocorticoids have a number of characteristics in common, including an increased risk of cardiovascular disease. Pediatric TS patients underwent studies of salivary cortisol (SC) and cortisone (SCn), body composition, continuous glucose monitoring, vascular ...

Ribozyme‐Catalyzed Site‐Specific Labeling of RNA Using O6‐alkylguanine SNAP‐Tag Substrates

Angewandte Chemie, EarlyView.
SNAPR is a ribozyme that repurposes O6‐benzylguanine SNAP‐tag substrates for site‐specific labeling of RNA with bioorthogonal alkyne and azide functional groups, fluorophores or photocrosslinkers. The N1A‐alkylated RNA products were converted to N6A‐modified RNA by Dimroth rearrangement.

A Novel Merocyanine Derivative for Probing Polarity at Cubosome Interfaces

Asian Journal of Organic Chemistry, EarlyView.
This study develops a synthetic route to C10SP, a polarity‐sensitive sensor embedded in phytantriol‐based cubosomes. Strategic steps included tertiary amine‐mediated amidation to covalently attach a hydrophobic tail and controlled nitrogen methylation to form the iminium moiety within the indolenine scaffold.

Characterization of Noncovalent Complexes of Polyelectrolytes by Mass Spectrometry [PDF]

, 2015
Various ions of poly-L-lysine and polystyrene sulfonic acid were successfully observed first within a matrix-assisted laser desorption/ionization mass spectrometer and subsequently in an electrospray ionization mass spectrometer.

Structural Insight Into a Human H Ferritin@Gold‐Monocarbene Adduct: Aurophilicity Revealed in a Biological Context

Angewandte Chemie, EarlyView.
Human H ferritin (HuHf) is a nanocarrier for anticancer metal drugs. By cryo‐EM, a 1.51 Å structure of its adduct with Au(NHC)Cl was solved, showing a novel tetranuclear gold(I) cluster bound to Cys90 and Cys102. Short inter‐metal distances indicate aurophilic interactions.

Tuning Antiaromaticity Through Meso‐Substituent Orientation in Core‐Modified Isophlorins

Asian Journal of Organic Chemistry, EarlyView.
The antiaromaticity of dithiadioxaisophlorins is controlled by the steric bulkiness of meso‐substituents through their tilt angle relative to the macrocycle. Bulkier substituents maintain larger angles, preserving stronger antiaromaticity, while smaller groups facilitate π‐conjugation with the macrocycle, diminishing antiaromaticity.

Antiparallel β‐Sheet as a Key Motif of Amyloid‐β Inhibitor Designed via Topological Peptide Reprogramming

Angewandte Chemie, EarlyView.
Targeting Amyloid‐β (Aβ) aggregation requires a peptide‐based approach that accounts for the structural heterogeneity of Aβ. Here, we employ topological reprogramming via disulfide bonds to stabilize antiparallel β‐sheets within the dimeric peptide.

Alterations in gut microbiota and metabolites contribute to postoperative sleep disturbances

Animal Models and Experimental Medicine, EarlyView.
In this study, we classified postoperative patients into poor sleepers (PS) and good sleepers (GS) based on the bispectral index (BIS), and transplanted their fecal microbiota to pseudo‐germ‐free rats to analyze the sleep changes in rats and the potential mechanism.

Fluoride Enhances Alcohol Binding Within a Trigonal‐Prismatic Metal‐Organic Capsule

Angewandte Chemie, EarlyView.
Steric hindrance from methyl groups orients rectangular ligands “landscape”‐wise, forming a trigonal prismatic capsule with a large cavity. Endohedral functionalization of this capsule via fluoride binding tunes its guest affinity, enhancing the binding of alcohols over ketones and enabling selective perrhenate encapsulation and release, offering an ...

Identifying the optimal dose of cannabidiol by intrabuccal administration in Kramnik (C3HeB/FeJ) mice

Animal Models and Experimental Medicine, EarlyView.
Cannabidiol (CBD) has numerous therapeutic properties, and is used to treat neurological conditions, such as neuroinflammation. However, the optimal dose of CBD to penetrate the brain requires further investigation. The primary aim of this study was to use a mouse model and the intrabuccal route for CBD administration to determine the optimal dose at ...
