Filed: 1995-03-27
Abstract: A method is disclosed for reducing excitotoxic damage to neurons, which can occur as a result of stroke, cardiac arrest, or other events or conditions. This method involves administering an aminoglycoside that suppresses the flow of calcium ions into neurons through N-type calcium channels. To be effective for such use, an aminoglycoside must suppress N-channel activity at a potency greater than streptomycin.      Aminoglycosides which meet this criterion (which includes neomycin and Gentamicin) can suppress the depolarizing activation of neurons, which in turn controls the release of glutamate, a neurotransmitter that becomes an endogenous toxin under excitotoxic conditions. Numerous aminoglycosides were tested in in vitro screening tests using brain cell membrane fragments to evaluate N-channel blocking potency.      Aminoglycosides with the highest N-channel blocking potency were then tested using (1) in vitro tests on hippocampal brain tissue, to evaluate recovery of neuronal activity after a period of oxygen deprivation; (2) in vivo tests to evaluate the control of induced seizures in intact adult mammals: and (3) in vivo tests to evaluate the reduction of brain damage due to surgically-induced ischemia in intact adult mammals. The results showed that (1) aminoglycosides which are more potent than streptomycin in blocking N-channel ion flow are effective in reducing excitotoxic brain damage, without causing undesired side effects, and (2) the effectiveness of all BBB-permeable aminoglycosides tested to date in preventing excitotoxic brain damage is directly correlated with their potency in suppressing N-channel activity. Evaluation of chemical structures also indicates a correlation between the number of primary amino groups on an aminoglycoside, and its potency as an N-channel blocker and neuroprotective agent.

Abstract: An air directional louver device, which incorporates one or more multi-grooved ratchet style notches to cooperate with corresponding mating fixed knife edge to mesh together.   Once the rotating ratchet grooves on the louver's axles and one or more fixed knife-edge pointer are meshed,  the louver can be held better in the last desired air direction set position than without the ratchet and pointer.  The rotating ratchet will help prevent also vibration and/or the forced air to the louver or to the fixed knife-edge pointer area from moving the louver frame to another undesirable position.  The fixed knife edge pointer, in another embodiment, will be rounded at its point for smoother operation and applied into the louver's corresponding holding area.  Further increase in the friction to change the louver position from one notch to another is attained by rounding the point and deepening the notches if desired.

Title: Resolution method and means for making expanded polymer products
Inventor: GUSTAFSSON PER ERIK
IPC: B29B13/08
Filed: 1994-02-22
Abstract: The present invention is for method and means by the manufacture of a product of expanded polymer, by which is obtained a weight per unit volume which is essentially lower than that of homogenous expanded material.  The starting material for the manufacture of a product according to the invention can be either a specially manufactured starting material or scrap and recovered material.  The pieces of expanded polymer are supplied in controlled quantities through a feeder to a space for the application of glue drops which are sprayed into the space from one or more dies.  In the space the pieces of polymer are dried by means of microwave energy which is obtained from an energy generator and magnetrones.  The dried pieces of polymer then are discarded from the space together with the air flow through the opening.  By the manufacture of a product according to the invention one starts from the pieces with glue applied to them as described above.  The pieces are put into some kind of mould wherein they are pressed against each other. Thereupon the material is heated so that the glue becomes sticky and the pieces attach to each other.  The heating is done by means of microwave energy which finds its way into and homogenously heats the whole volume of material.  The method according to the invention makes it possible to manufacture products which retain their elasticity and have a weight per volume unit essentially lower than that of the starting material.
