Nanosensor for Fe(II) and Fe(III) Allowing Spatiotemporal Sensing .

Fluorescent nanosensors operating have shown recent success toward informing basic plant biology and agricultural applications. We developed near-infrared (NIR) fluorescent nanosensors using the Corona Phase Molecular Recognition (CoPhMoRe) technique that distinguish Fe(II) and Fe(III) species with limit of detection as low as 10 nM. An anionic poly(p-phenyleneethynylene) (PPE) polyelectrolyte wrapped single-walled carbon nanotube (SWNT) shows up to 200% turn-on and 85% turn-off responses to Fe(II) and Fe(III), respectively, allowing spatial and temporal analysis of iron uptake in both foliar and root-to-shoot pathways.

Cholesterol metabolism regulator SREBP2 inhibits HBV replication via suppression of HBx nuclear translocation.

The intricate link between cholesterol metabolism and host immune responses is well recognized, but the specific mechanisms by which cholesterol biosynthesis influences hepatitis B virus (HBV) replication remain unclear. In this study, we show that SREBP2, a key regulator of cholesterol metabolism, inhibits HBV replication by interacting directly with the HBx protein, thereby preventing its nuclear translocation. We also found that inhibiting the ER-to-Golgi transport of the SCAP-SREBP2 complex or blocking SREBP2 maturation significantly enhances HBV suppression.

Super-strong hydrogel reinforced by an interconnected hollow microfiber network via regulating the water-cellulose-copolymer interplay.

The discontinuous fiber reinforced hydrogels are easy to fail due to the fracture of the fiber matrix during load-bearing. Here, we propose a novel strategy based on the synergistic reinforcement of interconnected natural fiber networks at multiple scales to fabricate hydrogels with extraordinary mechanical properties. Specifically, the P(AA-AM)/Cel (P(AA-AM), poly(acrylic acid-acrylamide); Cel, cellulose) hydrogel is synthesized by copolymerizing AA and AM on a substrate of paper with an interconnected hollow cellulose microfiber network.

Auricular vagus nerve stimulation for mitigation of inflammation and vasospasm in subarachnoid hemorrhage: a single-institution randomized controlled trial.

Objective: Inflammation contributes to morbidity following subarachnoid hemorrhage (SAH). The authors of this study evaluate how applying noninvasive transauricular vagus nerve stimulation (taVNS) can target this deleterious inflammatory response following SAH and reduce the rate of radiographic vasospasm.

Methods: In this prospective, triple-blinded, randomized controlled trial, 27 patients were randomized to taVNS or sham stimulation.

Endoscopic retrograde cholangiopancreatography for patients aged ninety and older with choledocholithiasis: A single-center experience in south China.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) serves an essential role in treating biliary diseases, especially in choledocholithiasis. However, due to the limited human lifespan, there remains a paucity of clinical investigations on ERCP treatment in patients over 90 years old.

Aim: To explore the effectiveness and safety of ERCP in super-older patients aged ≥ 90 years with choledochal stones.
