Chylous Reflux in Pediatric Primary Lymphedema of the Lower Limbs and Genitalia: A Retrospective Study of 167 Patients.

Chylous reflux (CR) in primary lymphedema (PL) of the lower extremities is rare and requires particular diagnostic procedures. This study aimed to determine clinical and lymphoscintigraphic traits for efficient screening. Pediatric patients with PL of lower extremities treated in our institution between January 2020 and December 2023 were reviewed.

Review on bile dynamics and microfluidic-based component detection: Advancing the understanding of bilestone pathogenesis in the biliary tract.

Bilestones are solid masses found in the gallbladder or biliary tract, which block the normal bile flow and eventually result in severe life-threatening complications. Studies have shown that bilestone formation may be related to bile flow dynamics and the concentration level of bile components. The bile flow dynamics in the biliary tract play a critical role in disclosing the mechanism of bile stasis and transportation.

Gelation of Hole Transport Layer to Improve the Stability of Perovskite Solar Cells.

To achieve high power conversion efficiency (PCE) and long-term stability of perovskite solar cells (PSCs), a hole transport layer (HTL) with persistently high conductivity, good moisture/oxygen barrier ability, and adequate passivation capability is important. To achieve enough conductivity and effective hole extraction, spiro-OMeTAD, one of the most frequently used HTL in optoelectronic devices, often needs chemical doping with a lithium compound (LiTFSI). However, the lithium salt dopant induces crystallization and has a negative impact on the performance and lifetime of the device due to its hygroscopic nature.

Mouse tail models of secondary lymphedema: fibrosis gradually worsens and is irreversible.

Although the mouse tail model of secondary lymphedema has been widely used in research, our knowledge regarding some of the characteristic changes in this model is lacking. Therefore, in the current study, we aimed to identify pathologic changes after surgery. Tail lymphedema was created in C57BL/6J mice by disconnecting both superficial and deep lymphatic vessels.

Reduction of intrinsic defects in hybrid perovskite films via precursor purification.

A simple chemical process was developed in a scalable manner, to reduce trap states in perovskite absorbers from the very beginning. The obvious decrease of I in methylammonium iodide and the decrease of trap density in the resultant films were identified, which led to the power conversion efficiency (PCE) of perovskite solar cells (PSCs) increase from 16.5% to 18.

A single molecular fluorescent probe for selective and sensitive detection of nitroaromatic explosives: A new strategy for the mask-free discrimination of TNT and TNP within same sample.

A simple naphthalene based fluorescent probe was first time reported as dual sensing of 2,4,6-trinitrotolune (TNT) and 2,4,6-trinitrophenol (TNP) by distinguishable changes in both solution color change and fluorescence within same sample without any mask agent. Upon addition of TNT and TNP, the strong emission quenching at 412nm and a new emission band at 530nm was observed, respectively. In addition, the sensing mechanism was evaluated by DFT calculations by Gaussian 09 software.
