Abstract: The present invention relates to targeting an intracellular enzyme for release of covalently linked bioactives which results in a synergistic effect between the bioactives. The present invention relates to the use of bioactives that are directly connected covalently or through a covalent molecular linker which have increased therapeutic activity when released as the free bioactives by intracellular enzymes as compared to when the bioactives are administered individually (i.e. not covalently linked). Further, methods are described of administering to patients in need thereof, bioactives as linked bioactives having increased therapeutic activity. Accordingly, this invention also relates to methods of treating patients for certain diseases.

Abstract: Provided are methods for determining the activity of proteins that modulate the acetylation state of a protein substrate. The methods may be used for determining both acetyltransferase activity and deacetylase activity. The methods utilize mass spectrometry for determining the acetylation state of a substrate peptide. The methods may also be used to identify compounds that modulate the activity of a protein having acetyltransferase or deacetylase activity. In some embodiments, a compound that modulates a deacetylase is an activator of the deacetylase.

Abstract: Provided are methods for determining the activity of proteins that modulate the acetylation state of a protein substrate. The methods may be used for determining both acetyltransferase activity and deacetylase activity. The methods involve fluorescence polarization measurements for determining the acetylation state of a substrate peptide. The methods may also be used to identify compounds that modulate the activity of a protein having acetyltransferase or deacetylase activity. Also provided are substrates for acetyltransferase or deacetylase enzymes for use in association with a fluorescence polarization assay.

Abstract: A system and method for measuring alveolar performance during ventilation using a microphone positioned adjacent to the distal end of a ventilation tube. The microphone is connected to a monitor that filters the signals received from the microphone to eliminate unwanted noise, such as that caused by the heart and turbulent airflow through the large airways of the lungs. The desired signals are then amplified and displayed on a graph as a function of lung volume during inflation. A clinician may take appropriate ventilation strategies based on the results displayed by the system to avoid ventilator induced lung injuries and decrease the mortality rates of patients having acute respiratory distress syndrome.

Abstract: The invention discloses a novel method for preventing acute lung injury in a mammal following trauma. The method includes treating the mammal with an effective amount of a tetracycline prior to intrapulmonary accumulation of neutrophils.
