Abstract:
A computerized electro-oculographic (CEOG) system with feedback control of test stimuli comprises an integrated system for automated administration of electro-oculographic tests and visual evoked response test to a patient, automated processing (32) of the results derived from such tests, and automated feedback control (10, 26) of the test stimuli in accordance with the processed test results. The CEOG system is responsive to operator selection (44) of desired stimuli to be administered as well as to operator specification of various test stimuli characteristics, for automatically administering to the patient the test stimuli having the desired characteristics. Electrode test data derived therefrom are immediately recorded (40, 42) on-line, and are immediately and automatically analyzed to provide critical information for immediate display (38) in acceptable format and in a very short period of time. The integrated CEOG system is especially noteworthy for its use of the analyzed test data to control and vary the test stimuli (16) administered to the patient in accordance with the analyzed tests data results.
Abstract:
It was found that the depletion of HERV-PTN mRNA prevents human choriocarcinoma growth, invasion and angiogenesis. Growth, invasion and angiogenesis of a tumor containing human endogenous retrovirus-pleiotrophin (HERV-PTN) sequences may be inhibited by administration of a choriocarcinoma inhibiting amount of PTN-targeted ribozymes. A ribozyme of the formula: '5-GTTGCAGGGCTGATGAGTCCGTTAGGACGAAATCTTACATC-3' was found to be particularly useful for this purpose.
Abstract:
Gelators gel a variety of nonpolar and polar liquids. Moreover, gelation of various monomers with subsequent polymerization of the gelled monomers forms organic zeolites and membrane materials. An ionic gelator includes salts of compounds of formula (I), where R , R and R are the same or different hydrogen or organic groups including alkyl groups, alkenyl groups, alkynyl groups, aryl groups, arylalkyl groups, alkoxy groups, aryloxy groups; X is a Group IIIA or Group VA element; R is a steroidal group, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an arylalkyl group, an alkoxy group or an aryloxy group; and Y is a Group IA or Group VIIA element or one-half of a Group IIA or VIA element, that is, a divalent counterion. The gelling agent composition may include a single isomer or mixtures of isomers of the formula (I). A non-ionic gelator also includes compounds of the formula (II): R R R X where R , R , R and X are defined as above.

Abstract:
It has now been found that, at certain concentrations, sphingosylphosphorylcholine (SPC) in solution can be used for wound healing at concentrations of from 0.1 mu M to 500 mu M. It has been found that at concentrations of 2 mu M to 10 mu M, very good results could be obtained. Compositions may be prepared using pharmaceutically acceptable carriers for topical application or for injection in or near the site of the wound.
Abstract:
This invention provides a method of treating patients suffering from malaria whilst avoiding cardioarrhythmias, the improvement thereof comprising the administration of desbutylhalofantrine in place of halofantrine. Dosage of 500 mg every six hours for three doses on day one with repeat of that dosage on day 7 for a total dosage of 3000 mg is appropriate for most treatment purposes in adults. Desbutylhalofantrine may also be given at dosage of 50 to 1000 mg as a prophylactic measure. Dosage may be given daily or one day per week.
Abstract:
The present invention is directed to novel progesterone derivatives, as well as to pharmaceutical compositions thereof, and methods of treatment using the derivatives. More particularly, the invention relates to C7-substituted derivatives of the pregnene series. The present invention is directed to methods of treating multidrug-resistant tumors, and especially breast tumors, with novel C7-substituted progesterone analogs.
Abstract:
Antisense oligonucleotides that hybridize to segments of the mRNA corresponding to the cDNA for pleiotrophin inhibit synthesis of pleiotrophin in vitro and in vivo. Pharmaceutical compositions containing these oligonucleotides as the active ingredients also are disclosed.
Abstract:
A pharmaceutical composition comprising a compound of formula (I): wherein Z is COOH, COOCH3 or CH2OH, or a pharmaceutically acceptable salt thereof, for use in an anti-histaminic treatment which does not induce any significant cardiac arrhythmia, comprising administering a therapeutically effective amount of a compound of formula (I) to a human patient.
Abstract:
A method for placing various types of catheters into the pericardial space takes advantage of the fact that the right auricle is a thin-walled, low-pressure structure which can be readily penetrated without damaging the pericardium or the epicardium. The method avoids surgical trauma and the risks of general anesthesia and infection. A catheter (202) is guided downstream through one of the venae cavae (204) to the right atrium (110). Once inside the right atrium (110), the catheter is passed into the right auricle (108). The wall at the apex (112) of the right auricle (108) is then pierced to gain access to the pericardial space (106). The method can be used to provide electrical stimuli to the heart, to pick up an ECG signal, to deliver pharmacologic agents to the heart, to improve vascularization, to remove pericardial fluid for analysis or pericardiocentesis, or to inject a radio-labelled or echo-sensitive dye into the pericardial space for precision fluid imaging.
