摘要:
A method of isolating epithelial cells from a human skin tissue or internal organ tissue using trypsin and ethylenediamine tetraacetic acid (EDTA) simultaneously with the application of magnetic stirring, a method of preconditioning isolated biological cells by the application of physical stimulus, i.e., strain, are provided. Epithelial cells can be isolated by the method with increased yield, colony forming efficiency (CFE), and colony size. Also, the increased percentage of stem cells in isolated cells is advantageous in therapeutic tissue implantation by autologous or allogeneic transplantation. In skin cells preconditioned by the application of strain, cell division is facilitated, and the secretion of extracellular matrix components and growth factors and the activity of matrix metalloproteinases (MMPs) are improved. When preconditioned cells are implanted by autologous or allogeneic transplantation to heal a damaged tissue, the improved cell adhesion, mobility, and viability provides a biological adjustment effect against a variety of stresses or physical stimuli which the cells would undergo after implantation, with improved capability of integration into host tissue, thereby markedly improving the probability of success in skin grafting.

A hand carry type portable curing apparatus using a long-arc UltraViolet (UV) lamp for concentrating the external air on the long-arc UV lamp and enhancing cooling efficiency by disposing a fan at a tilt angle and in addition installing a means for forcibly inducing a flow of air inside is provided. The apparatus includes a housing having an accepting part therein, the long-arc UV lamp installed in the accepting part of the housing, and a fan installed in the housing and cooling the long-arc UV lamp. The fan is installed on the slant to tilt toward the front in a front surface of the housing.
摘要:
The present invention relates to a novel use of herbal extracts in a pharmaceutical composition for prevention and treatment of nephritis and, more particularly, to a pharmaceutical composition and a health functional food for prevention and/or treatment of nephritis that contains at least one herbal extract selected from the group consisting of a Crataegi Fructus extract, a Cinnamomi Cortex extract, a Prunella Spica extract, and an Equiseti Herba extract, a method for prevention and/or treatment of nephritis using the herbal extract, and a use of the herbal extract in preparation of a composition for prevention and/or treatment of nephritis. The herbal extract has a good therapeutic effect for nephritis on a nephritis model of which the nephritis is induced by a drug such as gentamicin, cisplatin, etc., and a good inhibitory activity on the growth of mesangial cells in kidneys, thereby providing a very useful means for prevention and/or treatment of nephritis.

摘要:
Embodiments relate to systems and methods for touch-based two-stage text input. An electronic device (102), such as a wearable wireless device, can be configured with a two-stage input interface (116) on a display (104). A first stage can include a seek area (120), which displays a subset of letters or other symbols to represent the full range of symbolic elements that are available, in a compressed form. The user can identify an intended target range (128) by touching an area at or around the letter or other symbol of interest. That input triggers the display of a second stage of the interface in a separate selection area (122), in which all letters or other symbols in the target range are expanded and displayed. The user can then touch and lift off the letter or other symbol they wish to choose, for example, to insert in a message or application.
