Thread Embedding Acupuncture Inhibits Ultraviolet B Irradiation-Induced Skin Photoaging in Hairless Mice.

Thread embedding acupuncture (TEA) is an acupuncture treatment applied to many diseases in Korean medical clinics because of its therapeutic effects by continuous stimulation to tissues. It has recently been used to enhance facial skin appearance and antiaging, but data from evidence-based medicine are limited. To investigate whether TEA therapy can inhibit skin photoaging by ultraviolet B (UVB) irradiation, we performed analyses for histology, histopathology, in situ zymography and western blot analysis in HR-1 hairless mice.

Determination of N-nitrosodiethanolamine, NDELA in cosmetic ingredients and products by mixed mode solid phase extraction and UPLC-tandem mass spectrometry with porous graphitic carbon column through systemic sample pre-cleanup procedure.

A rapid, sensitive, accurate and specific ultra-performance liquid chromatography coupled to tandem mass spectrometry (UPLC-MS/MS) method for the detection of N-nitrosodiethanolamine (NDELA), a highly toxic contaminant in cosmetic raw materials and products was developed and validated. Systematized sample preparation steps were developed according to product types. Various SPE cartridges and columns were examined to establish the condition of SPE and chromatographic separation for NDELA.

Effect of acupressure on nausea and vomiting during chemotherapy cycle for Korean postoperative stomach cancer patients.

Despite the development of effective antiemetic drugs, nausea and vomiting remain the main side effects associated with cancer chemotherapy. The purpose of this study was to examine the effect of acupressure on emesis control in postoperative gastric cancer patients undergoing chemotherapy. Forty postoperative gastric cancer patients receiving the first cycle of chemotherapy with cisplatin and 5-Fluorouracil were divided into control and intervention groups (n = 20 each).
