Novel Cosmetic Ingredient CS-AA Polyion Complex and Skin Moisturizing Effect.

Purpose: The study explored the enhanced skin moisturizing capabilities and moisture retention effects achieved by forming a polyion complex using sulfated glycosaminoglycan (GAG), specifically chondroitin sulfate (CS), and amino acids (AA) such as glutamine (Q) and arginine (R). The overall hydration effect of this CS-AA complex was examined.

Methods: After analyzing the CS-AA polyion complex structure using spectroscopic methods, the ex vivo moisture retention ability was assessed under dry conditions using porcine skin samples.

Enhancement of Exfoliating Effects through the Novel Cosmetic Ingredient Mandelic acid_Carnitine Ion-Pairing Complex.

Purpose: This study aimed to develop a novel exfoliating material with high efficacy and low irritation by synthesizing the Mandelic acid_Carnitine ion pairing complex (M_C complex) and evaluating its exfoliating properties. Additionally, the study assessed the skin improvement effects of the M_C complex through clinical evaluations.

Methods: The M_C complex was synthesized in a 1:1 molar ratio of Mandelic acid and Carnitine.

Improving and evaluating the adhesion and stability of make-up by enhancing the affinity between skin/make-up layer.

Purpose: Make-up clumps, bumps and collapses are the three factors that determine how well make-up has been performed. The purpose of this study is to reduce the three factors mentioned above by using amphiphilic substances to increase the affinity between the skin and the make-up layer. In addition, it aims to evaluate the improvement of the make-up layer by developing an objective make-up layer evaluation method.

Reduction of enlarged facial pore using ion-paired amino acid through enhancement in skin permeation and exfoliation: A placebo-controlled in vivo study.

Background: Serine is a hypoallergenic but inefficient chemical exfoliant. Serine paired with arginine (ion-paired amino acid, IPA) shows enhanced lipophilicity, skin permeation, and exfoliation efficacy.

Aim: This study was conducted to determine whether exfoliation using an emulsion containing IPA could reduce enlarged facial pores and improve the dermis density.

5 nm Silver Nanoparticles Amplify Clinical Features of Atopic Dermatitis in Mice by Activating Mast Cells.

The triggering effect of silver nanoparticles (NPs) on the induction of allergic reactions is evaluated, by studying the activation of mast cells and the clinical features of atopic dermatitis in a mouse model. Granule release is induced in RBL-2H3 mast cells by 5 nm, but not 100 nm silver NPs. Increases in the levels of reactive oxygen species (hydrogen peroxide and mitochondrial superoxide) and intracellular Ca in mast cells are induced by 5 nm silver NPs.

Quantum efficiency of colloidal suspensions containing quantum dot/silica hybrid particles.

We have investigated the fluorescence properties of colloidal suspensions conntaining quantum dot (QD)/silica hybrid particles. First, we synthesized QD/silica hybrid particles with silica-QD-silica (SQS) core-shell-shell geometry, and monitored the quantum efficiencies of their suspensions at various particle concentrations. We found that the quantum efficiency (QE) of SQS particles in deionized (DI) water was much lower than that of the QDs even at low particle concentration, mainly due to the light scattering of emitted photons at the silica/water interface, followed by reabsorption by QDs.

Wheel Balanced Cancer Therapy for Longer Than 21 Days Can Have a Positive Effect on the Survival of Patients with Stage IV Cancer.

Objectives: Correlations of the levels of the nonspecific inflammatory markers C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) and of the coagulation marker fibrinogen with the treatment period of wheel balanced cancer therapy were determined.

Methods: Electronic charts of stage IV cancer patients hospitalized from February 1, 2008, to November 30, 2013, were reviewed retrospectively. Patients whose laboratory follow-up tests included at least two data points for at least one marker were included.

Bee venom pharmacopuncture: an effective treatment for complex regional pain syndrome.

Objectives: Treating complex regional pain syndrome (CRPS) is difficult because it still does not have a recommended therapy. A 29-year-old man was diagnosed with CRPS after surgery on his 4(th) and 5(th) left toes 7 years ago. Though he had undergone diverse pain treatment, the symptoms persisted, so he visited Dunsan Korean Medicine Hospital of Daejeon University.

Anesthetic experience using extracorporeal membrane oxygenation for cesarean section in the patient with peripartum cardiomyopathy: a case report.

Peripartum cardiomyopathy is a rare form of cardiomyopathy that is associated with significant mortality. It can cause a cardiac arrest during cesarean section even though the patient does not have any previous symptom and sign. The most important thing of anesthesia in this patient is an optimization of hemodynamic and respiratory status.
