Novel method for correcting cephalic rotation in Asian nasal tip plasty.

Background: To correct nasal tip cephalic rotation, SEG made of cartilage or Medpor are often used in rhinoplasty. These techniques require extensive experience for the surgeon, and not all patients can accept this procedure. In this research, we introduce a new method to correct nasal tip cephalic rotation that is relatively simple and rapid.

Boosting electron transport process over multiple channels induced by S-doped carbon and FeS NPs interface toward high-efficiency antibiotics removal.

The enhancement of electron transport process on multiple channels of C-Fe and C-S-Fe bonds between dual-reaction centres was investigated for stimulating the antibiotics degradation in Fenton-like processes. Herein, multiple channels structure of sulfur-doped carbon coupled FeS cluster through C-Fe bond and C-S-Fe bond was constructed through density functional theory (DFT), and S-doped carbon framework coated FeS nanoparticles (FeS/SC) Fenton-like catalyst was prepared through hydrothermal and subsequent sulfuration process. The DFT calculations revealed that electrons are thermodynamically transferred from carbon to iron along both C-Fe and C-S-Fe bonds.

The as-obtained immobilized coating manifested a remarkable catalytic activity that the removal efficiencies of phenol and various antibiotics could reach more than 92% within 90 min, and presented excellent reusability after six runs in phenol removal.

Revealing the enhancing mechanisms of Fe-Cu bimetallic catalysts for the Fenton-like degradation of phenol.

To develop a heterogeneous Fenton-like catalyst with desirable activity and reusability remains a great challenge for the practical degradation of environmental remediation. Herein, we demonstrate a dendritic Fe-Cu bimetallic catalyst consisted of a Cu/FeO shell and a FeCu core (E100). In comparisons of single Cu, Fe and FeO, E100 performs far better performance for the Fenton-like degradation of phenol, and its dominant Fenton-like active centers are Fe species under acidic pH or Cu species under neutral pH.

Surgical reconstruction of massive scrotal lymphedema associated with hidradenitis suppurativa: a case report.

Hidradenitis suppurativa (HS) is a chronic, recurrent inflammatory cutaneous disease affecting apocrine glands. It can be associated with lymphedema of the surrounding tissues and most commonly affects scrotum. As a debilitating complication of HS, lymphedema can cause significant morbidity and further exacerbate HS condition, thus causing a vicious cycle.

Significantly Improved Dielectric Performance of Poly(1-butene)-Based Composite Films via Filling Polydopamine Modified Ba(ZrTi)O-Coated Multiwalled Carbon Nanotubes Nanoparticles.

The low dielectric constant of the nonpolar polymer poly(1-butene) (PB-1) limits its application as a diaphragm element in energy storage capacitors. In this work, Ba(ZrTi)O-coated multiwalled carbon nanotubes (BZT@MWCNTs) were first prepared by using the sol-gel hydrothermal method and then modified with polydopamine (PDA) via noncovalent polymerization. Finally, PB-1 matrix composite films filled with PDA-modified BZT@MWCNTs nanoparticles were fabricated through a solution-casting method.

Highly Selective Electrocatalytic Reduction of CO into Methane on Cu-Bi Nanoalloys.

Methane (CH), the main component of natural gas, is one of the most valuable products facilitating energy storage via electricity conversion. However, the poor selectivity and high overpotential for CH formation with metallic Cu catalysts prevent realistic applications. Introducing a second element to tune the electronic state of Cu has been widely used as an effective method to improve catalytic performance, but achieving high selectivity and activity toward CH remains challenging.

Self-Assembly of Amphiphilic Linear-Dendritic Carbosilane Block Surfactant for Waterborne Polyurethane Coating.

The traditional two-component waterborne polyurethane coating system cannot effectively inhibit the undesirable side reaction between polyisocyanate and water during curing hardening. It is difficult to avoid the microbubbles formed by this reaction during the film formation process, which severely degrades the appearance and decreases the performance of the film. Therefore, the addition of an amphiphilic Linear-Dendritic carbosilane Block Surfactant (LDBS) to the hardener can physically separate the polyisocyanate emulsion from water through self-assembly.

Background: Primary genital lymphedema is caused by congenital lymphatic dysplasia, which is often accompanied by lymphedema of the lower extremities. A lack of effective diagnostics and treatments are available in clinical practice. The purpose of this study is to present the experience of surgical treatment of genital lymphedema and follow-up magnetic resonance lymphangiography (MRL) examinations.

n-type polyaniline hole-blocking layer for high-efficiency QDSC by one-pot electropolymerization and selective aprotic cation ([EMIM]) doping.

In the field of clean solar-to-current devices, the photoelectron transfer process is essential for photovoltaic conversion in the typical n-i-p solar-cell structure. With regard to the oriented injection and ejection of photoelectrons, the development of hole-blocking layer (HBL) materials with a high electron transfer capability are exceedingly desirable. Profiting from the distortion of the p-π electron cloud attracted by a doped aprotic cation, a modified n-type polyaniline (PANI) as the HBL of a photoanode has been successfully fabricated through a facial one-pot square-wave potentiostatic electropolymerization method.

Angiopoietin-Tie signaling in kidney diseases: an updated review.

Angiopoietins (Angs) are a family of vascular growth factors that share multiple cellular functions related to cell survival, proliferation, and migration. Angs play physiological and pathological roles through the Tie tyrosine kinase receptors. The Ang-Tie signaling pathway participates in the developmental and tumor-induced angiogenesis and is also involved in many disease settings, such as vascular diseases, systemic inflammation, and cancers.

Magnetic Resonance Lymphography of Lymphatic Vessels in Upper Extremity With Breast Cancer-Related Lymphedema.

Background: Magnetic resonance lymphangiography (MRL) has been proven to be able to visualize pathological lymphatic networks and accompanying complications through subcutaneous injection of commonly used contrast agents. However, no comprehensive prior studies have previously been reported regarding MRL for the evaluation of upper extremity lymphedema in patients with breast cancer-related lymphedema (BCRL). In this study, we establish a novel MRL protocol to characterize the normal and abnormal characteristics of different clinical stages of BCRL in patients using high-spatial-resolution MRL.

IL-7 enhances the differentiation of adipose-derived stem cells toward lymphatic endothelial cells through AKT signaling.

Our study was designed to investigate the effects of IL-7 during the differentiation process of adipose-derived stem cells (ADSCs) toward lymphatic endothelial cells (LECs). IL-7 was added to the traditional induced medium, which was called the IL-7 (+) group, while the group that used traditional induced medium was called the IL-7 (-) group. After 7 days of induction of ADSCs, a comprehensive analysis was conducted between these two groups.

Construction of TiO Nanotubes/C/MnO Composite Films as a Binder-Free Electrode for a High-Performance Supercapacitor.

Although titanium dioxide (TiO) exhibits excellent promise in electrode materials for supercapacitors, its poor conductivity and low areal specific capacitance hamper further development. In this work, we have designed a clever way to deposit manganese dioxide (MnO) in order to improve its electrochemical performance via a facile and typical hydrothermal method. In a hydrothermal process, carbon (C), which deposited via new gas thermal penetration, acts as a reducing agent, while a potassium permanganate (KMnO) solution acts as an oxidant.

Surface Ligand Promotion of Carbon Dioxide Reduction through Stabilizing Chemisorbed Reactive Intermediates.

We have explored functionalizing metal catalysts with surface ligands as an approach to facilitate electrochemical carbon dioxide reduction reaction (CORR). To provide a molecular level understanding of the mechanism by which this enhancement occurs, we combine in situ spectroscopy analysis with an interpretation based on quantum mechanics (QM) calculations. We find that a surface ligand can play a critical role in stabilizing the chemisorbed CO, which facilitates CO activation and leads to a 0.
