摘要:
The present invention provides a compound in substantially pure form having the structure: ##STR1## wherein each of R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, and R.sub.8 may independently be hydrogen, halogen, nitro, CF.sub.3, hydroxy, C.sub.1-5 alkyl, aryl or OR.sub.9, wherein R.sub.9 is C.sub.1-5 alkyl, wherein R.sub.10 is COC.sub.1-5 alkyl; or wherein any two consecutive R groups may be members of a C.sub.5 -C.sub.6 membered ring, and wherein the intracyclic-dashed line represents a covalent bond which may be present or absent, with the proviso that when R.sub.10 is present, the exocyclic-covalent bond is absent, and when R.sub.10 is absent, the exocyclic-covalent bond is present, and with the proviso that when R.sub.10 is absent, R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, and R.sub.8 cannot all be hydrogen and when R.sub.10 is absent, R.sub.5, R.sub.6, R.sub.7, and R.sub.8 cannot all be hydrogen when either R.sub.1, R.sub.2, R.sub.3, or R.sub.4 is hydroxy, or R2 is carboethoxy. The present invention further provides a composition comprising the compound described above in an amount effective to modulate cellular expression of a mammalian gene encoding erythropoietin and a carrier.
摘要:
A unique filtering face-piece respirator or mask that is constructed of filtration media capable of sub-micron particle absorption or filtration. Utilizing existing and broadly available low cost media, the mask is patterned from a single sheet of material. It is constructed in a manner that creates an adequate seal as it fits snugly to the user's face, creates structure to ensure a low volume air gap, and deploys unique vertical pleats to increase surface area in order to decrease pressure drop across the mask. Specifically, the design enables the user to inhale and exhale with a pressure drop below 0.4 inches of water at elevated breathing rates of up to 110 liters per hour. Valve design and positioning enable more than 90% of used air to be exited the mask. Meeting these criteria, the mask is intended to be a low cost solution that provides protection from virus, air pollution, or other pathogens with little restriction, allowing subjectively ‘comfortable’ usage during sports and other highly aerobic activities.
摘要:
There is disclosed a computer apparatus incorporating a model component for calculating time series and a user interface component for controlling the model and displaying the time series. The user interface allows events to be defined which are used by the model, by positioning event markers relative to an event schedule graphic. The apparatus may be used as a financial planning tool, in which case the model is a financial model and the events are financial events. Such a planning tool may further incorporate a component to provide planning suggestions based on the model and defined events.
