An elastic head band which fits around a wearer's head from front to back wherein each end of such elastic band has part of attaching devices such that the head band will be held in place. The elastic band has essentially two purposes: one is decorative and the other is functional in that it helps to keep a wearer's wig in place. The wig in fact can be reversed from front to back and it further has a net attached to the inside. Further, a comb is fixedly attached to the front and back of the wig such that the wearer will insert the teeth of the comb into his or her natural hair. The band is meant to be replaceable and is attachable to the comb on the front of the wig by means of inserting the teeth of the comb into a plurality of loops disposed on the surface of the head band. Other means of attaching the head band to the inside of the wig may be employed. This may be in the form of button holes-buttons, male-female velcro, or any other well known fastening devices.

Provided herein are compositions, methods, systems, and kits for wound healing. As shown herein, CCN2/CTGF stimulated mesenchymal progenitor cells can form αSMA fibroblasts. Further, TGFβ was shown to stimulate further differentiation of αSMA fibroblasts to myofibroblasts associated with fibrosis. One aspect provides a composition including CCN2/CTGF and a TGFβ inhibitor, a P38 inhibitor, or a tyrosine kinase inhibitor. Another aspect provides a method of treating tissue wounds with CCN2/CTGF-containing compositions. Also provided are systems and kits for wound healing. Also provided are methods for forming αSMA fibroblasts mesenchymal progenitor cells.

An automatic service water tap is disclosed in which a battery operated motor is provided for controlling a water supply valve in response to the presence or absence of an object positioned within the range of an infrared generating and detecting system mounted in the tap. The valve operates using only a small amount of electric power under the control of a circuit which draws no electric power once the valve is moved to its opened or closed condition. Thus the consumption of the electric power is minimized to almost zero and the valve can be utilized for a long period of time only with a small single battery.
