Vertical Scar Reduction Mammaplasty Using the Superomedial-Based Pedicle Technique in Gigantomastia.

Background: Breast reduction surgery has witnessed significant advancements in recent years; however, it continues to pose challenges for both surgeons and patients when dealing with cases involving excessive breast volume and severe breast ptosis. This study aimed to assess the aesthetic outcomes and the impact on the quality of life, as measured by the BREAST-Q questionnaire, in patients with gigantomastia and severe breast ptosis who underwent reduction mammaplasty using the superomedial-based pedicle technique.

Methods: We present a retrospective series comprising 84 patients who underwent reduction mammoplasty utilizing the superomedial pedicle technique.

Platelet-Rich Fibrin in Fat Grafts for Facial Lipofilling: A Randomized, Controlled Split-Face Clinical Trial.

Objective: Previous studies have reported that platelet-rich fibrin (PRF) may enhance the efficacy of fat grafts in facial lipofilling. However, these studies either lacked objective data or were not randomized, controlled trials. Thus, we aimed to objectively evaluate the efficacy of PRF in facial lipofilling.

Response of salinity gradient power generation to inflow mode and temperature difference by reverse electrodialysis.

Sustainable utilization has been becoming the core idea of concentrated seawater disposal, which makes the harvest of salinity gradient power based on reverse electrodialysis (RED) become one of the important ways. As the important factors affecting RED performance, different flow orientations along the membrane and solution temperature have been studied in the previous researches. However, there are still some details that need to be clarified.

Wetting Behavior and Tribological Properties of Polymer Brushes on Laser-Textured Surface.

Polymer brush layers can act as effective lubricants owing to their low friction and good controllability. However, their application to the field of tribology is limited by their poor wear resistance. This study proposes a strategy combining grafting and surface texturing to extend the service life of polymer brushes.

CTLA-4 polymorphisms and systemic lupus erythematosus (SLE): a meta-analysis.

The aim of this study was to summarize results on the association of cytotoxic T-lymphocyte antigen-4 (CTLA-4) promoter exon-1 +49 and 1722T/C polymorphism with systemic lupus erythematosus (SLE) susceptibility by using the meta-analysis. We searched all the publications about the association between CTLA-4) promoter exon-1 +49 and 1722T/C polymorphism and SLE from PubMed, Elsevier Science Direct, Chinese Biomedical Literature Database (CBM), Chinese National Knowledge Infrastructure (CNKI), and Wanfang (Chinese). Previous CTLA-4 association studies with SLE, however, have produced inconsistent results.

Quantification of domoic acid in shellfish samples by capillary electrophoresis-based enzyme immunoassay with electrochemical detection.

A new method was developed to quantify domoic acid by capillary electrophoresis-based enzyme immunoassay (CE-EIA) with electrochemical (EC) detection. The method was based on noncompetitive immunoreaction between free domoic acid antigen (Ag) and excessive amount of horseradish peroxidase (HRP)-labeled antidomoic acid antibody tracer (Ab*) in liquid phase. Then the bound enzyme-labeled complex (Ab*-Ag) and unbound Ab* were separated by CE, and the system of HRP catalyzing H(2)O(2)/o-aminophenol (OAP) reaction was adopted for EC detection.

PDTC attenuate LPS-induced kidney injury in systemic lupus erythematosus-prone MRL/lpr mice.

Lipopolysaccharide (LPS) from bacteria can accelerate and exacerbate lupus nephritis (LN) and induce infiltrating inflammatory cells in kidney in animal models. Pyrrolidine dithiocarbamate (PDTC) is known to exert anti-inflammatory effects. Monocyte chemoattractant protein-1(MCP-1) is upregulated by various stimuli, including LPS, high glucose, and hyperosmolality.

Online preconcentration and two-dimensional separation of cationic compounds via hyphenation of capillary zone electrophoresis with cyclodextrin-modified micellar electrokinetic capillary chromatography.

A novel preconcentration/separation approach, which online combined CZE with CD-modified MEKC, was developed for simultaneous enhancing resolving power and detection sensitivity. CZE with cation-selective exhaustive injection and transient ITP preconcentration was used as the first dimension, from which the effluent fractions were further analyzed by CD-modified MEKC acting as the second dimension. As the key to successful integration of CZE with MEKC, a new interface was designed and electroaccumulation focusing strategy was employed to avoid analyte band diffusion at the interface.

Sequential preconcentration by coupling of field amplified sample injection with pseudo isotachophoresis-acid stacking for analysis of alkaloids in capillary electrophoresis.

A novel on-column sequential preconcentration method based on the combination of field-amplified sample injection induced by acetonitrile and pseudo isotachophoresis (ITP)-acid stacking is developed for simply but efficiently concentrating alkaloid cations in a high-salt sample matrix in capillary electrophoresis. Acetonitrile (70%) added to a sample solution with a high-salt sample matrix not only induces field-amplified sample stacking by decreasing conductivity but also acts as a termination reagent in the succeeding pseudo ITP. After sample injection had been completed, a plug of H(+) was injected electrokinetically and a neutralization reaction between H(+) and tartrate from the buffer solution produced a low conductivity zone, in which the injected analyte cations were further concentrated.

[Functions of spleen tyrosine kinase (Syk) gene and its correlation to neoplasms].

Spleen tyrosine kinase (Syk) was thought to be a hematopoietic cell-specific signaling molecule and plays an essential role in maturation of lymphocytes and activation of immune cells. Recent evidences show that it is also expressed by many non-hematopoietic cell types. Down-regulation of Syk expression was first observed during breast cancer progression, now its abnormal expression has also been detected in many other types of tumors.

Synthesis of methane in nanotube channels by a flash.

Inorganic synthesis of organic molecules is a significant step for the primordial life. Generally, inorganic synthesis of methane necessitates, in addition to catalyst, a high-temperature and high-pressure environment. Here we will show that such an environment could be locally and instantly realized in the channels of single-walled carbon nanotubes (SWNTs) even under room temperature and ultrahigh vacuum conditions just by a visible-light flash, owing to the ultra-photothermal effect of nanomaterials.
