The effects of climatic conditions on green tea metabolites in three different growing areas Jeju Island, South Korea, were investigated through global metabolite profiling by 1H nuclear magnetic resonance (NMR) spectroscopy. Pattern recognition methods, such as principal component analysis (PCA) and orthogonal projection latent structure−discriminant (OPLS-DA), revealed clear discriminations teas from the areas. Variations theanine, isoleucine, leucine, valine, alanine, threonine,...
Thread lifting is a minimally invasive technique for facial rejuvenation. Various devices thread using polydioxanone (PDO) are popular in aesthetic clinics Korea, but there have been few studies regarding its use.To describe PDO and techniques adopted to counteract the descent laxity of face.A retrospective chart review was conducted over 24-month period. A total 31 procedures were performed. On each side, 5 bidirectional cog threads used procedure flabby skin nasolabial folds. And,...
Platelet-rich plasma (PRP) is an autologous concentration of human platelets contained in a small volume and has recently been shown to accelerate wound healing rejuvenate aging skin. The current study was conducted determine whether there are additional effects PRP combined with fractional laser therapy.Twenty-two Korean women underwent three sessions laser; 11 were treated topical application laser. Evaluations done at baseline 1 month after the final treatment. outcome assessments...
Background: Striae distensae (striae alba) is a challenging cosmetic problem for which various treatment modalities have been applied. However, the of striae has not satisfactory. Objectives: This study was done to evaluate effectiveness and safety enhanced penetration platelet rich plasma with ultrasound after fractional radiofrequency distensae. Subjects method: Eighteen participants were treated Legato system (Alma Lasers, Israel) every two weeks total four sessions. Thereafter, in order...
Infraorbital laxity is a common problem that increases with age. Blepharoplasty lipectomy very commonly performed surgical procedure to treat this problem; however, it invasive and associated the potential for re-emergence. Therefore, young patients may prefer non-surgical rather than procedure. Intense-focused ultrasound (IFUS) has emerged as an effective, non-surgical, tissue-tightening procedure.This study assessed safety efficacy of IFUS (Ulthera system, Ulthera Inc, Mesa, AZ, U.S.A.)...
Abstract Background Three dimensional (3D) cell cultures can be effectively used for drug discovery and development but there are still challenges in their general application to high-throughput screening. In this study, we developed a novel chemotherapeutic 3D screening system gastric cancer, named 'Cure-GA', discover clinically applicable anticancer drugs predict therapeutic responses. Methods Primary cancer cells were isolated from 143 fresh surgical specimens by enzymatic treatment....
As a new approach to islet transplantation, biocompatible monomethoxy-poly(ethylene glycol) (mPEG) was chemically grafted onto the pancreatic capsule. The aim of this study determine optimal conditions for completely covering by mPEG while maintaining high viability islets according reaction time and repeating number reaction. By grafting fluorescein-PEG instead mPEG, we determined as 1 h, during which procedure did not reduce viability. Insulin secretion from where on 3 times similar that...

Cryolipolysis received U.S. Food and Drug Administration clearance for reducing fat from the flanks, abdomen, thighs. The upper arms are an off-label indication cryolipolysis, outcome data on using a cryolipolytic device has rarely been published.This pilot study evaluated cryolipolysis to reduce arm fat.A flat vacuum applicator was used treat seven subjects in single-side study. patients underwent one cycle of upper-arm treatment, contralateral served as control. Follow-up conducted at 8...
Intense focused ultrasound (IFUS) is a novel modality for treating skin laxity that produces thermal effects at various depths while sparing the overlying tissue. This study assessed histologic changes and safety efficacy of intense (Doublo(TM), HIRONIC Co., Sungnam, Korea) tightening facial in Asian patients.Eleven patients with were treated IFUS evaluated before after treatment. Mean age was 46 years (range, 35-64 years). Two available hand-pieces different focal (3 mm 4.5 mm) used three...
Cryolipolysis is a noninvasive method for the selective reduction of fat, especially proven to be safe and effective in body contouring. There demand submental which related not only with favorable appearance but also signs aging.This study evaluated efficacy safety cryolipolysis subcutaneous fat area Asians.Ten healthy Koreans were treated using contact device (CoolMini applicator, Zeltiq Aesthetics). The was applied on participant's neck twice via two lateral approaches. Patient's weight...
Background: Conventional procedures including botulinum toxin and filler injections have their limitations in improving deep wrinkles decreasing tissue laxity, possess the propensity for vascular accidents. Absorbable thread is a recently commercialized field, but there little evidence on comparative superiority. Objectives: We observed effects of polydiaxanone (PDO) threads with different number strands relation to collagen production histopathology rat model. Materials methods: Dorsal skin...
Objectives This clinical trial is registered at ClinicalTrials.gov. (NCT02476981) randomized, prospective double-blind study compared remifentanil with dexmedetomidine for monitored anaesthesia care during minimally invasive corrections of vertebral compression fractures (vertebroplasty or kyphoplasty). Methods Patients > 65 years age American Society Anesthesiologists (ASA) classification I–III, scheduled vertebroplasty kyphoplasty under care, received (i.v. infusion 1–5 µg/kg/h)...
The purpose of this study was to investigate the effect hydroxypropyl methyl cellulose phthalate (HPMCP) coating on digestive stability and intestinal transport green tea catechins (GTCs).Two types HPMCP were prepared: one type with size smaller than 500 μm (S-HPMCP) other larger (L-HPMCP). An in vitro gastrointestinal model system coupled Caco-2 cells used for estimating bioavailability GTCs. Ultraperformance liquid chromatography a photodiode array detector performed analyze GTCs.The GTCs...
Intense focused ultrasound (IFUS) is a novel treatment modality for skin laxity. The delivery of thermal energy to the deeper tissue layers effectively tightens but can also cause significant fat atrophy, limiting its use in patients with lean face.We sought evaluate safety and efficacy modified IFUS on facial rejuvenation.This was retrospective, single-center study 28 subjects age-related laxity who underwent 3 sessions (UltraskinTM, WONTECH Co., Daejeon, Korea) at an interval four weeks,...
Cryolipolysis treatment is a non-invasive option for localized fat reduction without damaging the surrounding tissue. Clinical studies about cryolipolysis show various side effects, including temporary erythema, bruising, and transient numbness. But, no reports are available on motor nerve malfunction after cryolipolysis. A 24-year-old female received abdomen, both arms. After 10 days, patient complained of weakness inability to lift heavy objects. Symptoms continued 6 months, fully...
