Abstract: A computer-implemented method of monitoring an intracranial pressure using a fluid exchange system. The method includes receiving, at a processor, a first pressure value in an intracranial cavity; infusing a liquid into the intracranial cavity; receiving, at the processor, a second pressure value of the intracranial cavity; computing, using the processor, a difference between the first and second intracranial pressures; and in an event the difference between the first and second intracranial pressures exceeds a first pressure threshold value or is less than a second pressure threshold value, issuing a pressure signal output, via the processor, to indicate the first pressure threshold value has been exceeded or the difference between the first and second intracranial pressures is less than the second pressure threshold value.

Abstract: A fluid exchange system may include a control unit comprising a processor; a tube set attachment removably connected to the control unit, the tube set attachment comprising a tube set fluidly connected to a fluid source and a drainage receptacle; a catheter fluidly connected to the tube set; and at least one sensor positioned on at least one of the control unit and the tube set attachment, wherein the control unit may be configured to supply fluid to a patient through the tube set and drain fluid from the patient via the tube set, and wherein the control unit may be configured to receive measurements from the at least one sensor to adjust the supply of the fluid to the patient and the drainage of the fluid from the patient.

Abstract: This invention provides a Togavirus-amplified retrovirus vector and a novel method for packaging a retrovirus cassette that contains a heterologous nucleic acid, which is amplified in a packaging cell cytoplasm by a Togavirus vector. The retroviral cassette is packaged into infectious retrovirus particles by retroviral packaging cells. These retroviral particles carrying the retroviral packaging cassette are then used to infect host cells.

Abstract: The invention provides for methods and compositions for identifying proteins or chemicals that directly or indirectly modulate a genomic polynucleotide and methods for identifying active genomic polynucleotides. Generally, the method comprises inserting an adeno-associated virus derived expression construct having a reporter gene into an eukaryotic genome, usually non-yeast, contained in at least one living cell, contacting the cell with a predetermined concentration of a modulator, and detecting reporter gene expression in the cell.
