A Dynamic Gate Enables Regioselective Hydroxylation of Free Arginine by a Non‐Canonical Heme Enzyme

Advanced Science, EarlyView.
The YqcI/YcgG enzyme AglA employs a unique “sandwich” fold and a dynamic gating mechanism to selectively hydroxylate AMPn‐Arg at Nε. Site‐directed mutations reprogram regioselectivity or enable activity on free arginine by altering hydrogen‐bond networks, precisely positioning substrates.

New analytical challenges in characterization of antibody-drug conjugates

Journal of Chromatography Open
Since 1913, when Paul Ehrlich introduced the concept of “selective toxicity”, new strategies to obtain quality control, quantification of the drug were mandatory. For this reason, the introduction of antibody drug conjugates (ADC) has shown many critical

Statistical modeling of STR capillary electrophoresis signal

BMC Bioinformatics, 2019
Background In order to isolate an individual’s genotype from a sample of biological material, most laboratories use PCR and Capillary Electrophoresis (CE) to construct a genetic profile based on polymorphic loci known as Short Tandem Repeats (STRs).

Immunomodulatory Hydrogel Coating with SeNPs and Lithium Silicate Synergistically Promotes Osseointegration and Prevents Infection on Titanium Implants

Advanced Science, EarlyView.
This study introduces a multifunctional hydrogel coating (Lap‐CMCSMA/GelMA@SeNPs) that scavenges ROS, modulates immune responses, and shows strong antibacterial activity. It effectively restores the peri‐implant microenvironment. The coating exhibits excellent biocompatibility and promotes osteogenic differentiation.

Microfluidic Electrochemical Biosensor for the Detection of Platelet Factor 4 Antibody‐Mediated Thrombotic Disorders

Advanced Science, EarlyView.
A microfluidic electrochemical biosensor enables sensitive and specific detection of antibodies associated with vaccine‐induced immune thrombotic thrombocytopenia (VITT) and heparin‐induced thrombocytopenia (HIT). The platform uses two antigen targets— platelet factor 4 (PF4) and cross‐linked‐PF4 (c‐PF4)—and microliter volumes of patient sera to ...

Connexin 26 Functions as a Direct Transcriptional Regulator During the Cochlea Development

Advanced Science, EarlyView.
Connexin26 can not only form intercellular channels that mediate rapid communication on the cell membrane, but also enter the nucleus as a transcription factor to directly regulate the transcription of nuclear genes. In the developing cochlea, Cx26 can control the maturation of the molecular scissor ADAM10 by regulating the transcription of TspanC8 ...

Capillary Electrophoresis for Sampling Single Nerve Cells

CHIMIA, 1991
Two micro-capillary electrophoresis techniques are underdevelopment to acquire and determine catecholamines in single nerve cells. The first method involves the analysis of neurotransmitters in a portion of cytoplasm withdrawn from a single cell,

In Situ Lipoprotein‐seeking Dye for in Vivo Real‐Time Imaging of Lipid Dysregulation Diseases

Advanced Science, EarlyView.
This study develops lipoprotein‐seeking NIR‐II dyes that specifically bind circulating lipoproteins. These dyes form ultra‐stable complexes with endogenous lipoprotein, enabling real‐time, high‐contrast imaging of fatty liver and atherosclerotic plaques. Tunable binding kinetics allow customized imaging windows.
