Bending‐Resistant Intimate 3D Graphene–Metal Heterojunctions for Highly Sensitive and Robust Flexible Sensors

Advanced Science, EarlyView.
A reservoir‐guided silver‐nanoparticle soldering strategy is developed for bending‐resistant 3D graphene–metal heterojunctions. Controlled hot‐plate evaporation confines conductive ink within the metal reservoir, suppressing spreading and protecting the LIG interface from deformation‐induced fracture.

Remote Magnetomechanical Neuromodulation Uncovers Therapeutic Mechanisms for Alleviating Parkinsonian Symptoms in Freely Moving Mice

Advanced Science, EarlyView.
Magnetomechanical neuromodulation using magnetic nanodiscs enables remote activation of neurons. In a hemiparkinsonian mouse model, alternating magnetic fields actuate the nanodiscs to generate torque that opens mechanosensitive ion channels within the subthalamic nucleus, thereby modulating basal ganglia motor circuitry.

Herba Lysimachiae Polysaccharide‐Modified Selenium Nanoparticles Alleviate Oxidative Injury in Kidney Stones via TOMM22‐Regulated Mitophagy Activation

Advanced Science, EarlyView.
HLP‐SeNPs, a Lysimachia christinae polysaccharide‐modified selenium nanoparticle, treat kidney stones by downregulating TOMM22 expression, which reduces PINK1 translocation into mitochondria and promotes its retention on the outer mitochondrial membrane.

Scurvy may occur even in children with no underlying risk factors: a case report

Journal of Medical Case Reports, 2020
Background Since ancient times, scurvy has been considered one of the most fearsome nutritional deficiency diseases. In modern developed countries, this condition has become very rare and is only occasionally encountered, especially in the pediatric ...

An Unexpected Case of Scurvy in a Peritoneal Dialysis Patient

Case Reports in Nephrology and Dialysis, 2017
This case describes an obese adult male peritoneal dialysis patient who presented with a pruritic follicular rash. Nutrient deficiency was not suspected initially in this case because there was no history of protein-calorie malnutrition, but the patient ...

Re-evaluation of Ascorbic Acid Deficiency in Hemodialysed Patients

The International Journal of Artificial Organs, 1987
In 92 uremic patients under chronic hemodialysis without ascorbic acid supplementation, serum ascorbic acid was measured before hemodialysis and between two sessions. The results indicated a more serious ascorbic acid deficiency of patients than in previous studies.

Protein Structuromics Reveals a Loop‐Controlled Half‐Open Active Pocket Conformation Throughout Fe(II)/α‐ketoglutarate‐Dependent Dioxygenase Catalytic Cycle

Advanced Science, EarlyView.
This study reveals a conserved half‐open active pocket in Fe(II)/α‐ketoglutarate‐dependent dioxygenases through protein structuromics, distinguished by structural features comprising highly flexible loop elements. Enhanced sampling simulations‐guided mutagenesis experiments elucidated how this flexible loop regulates pocket open/closed conformations ...
