A method for administration of citrulline for the treatment of sickle cell disease and other complications of sickle cell disease thereof.

Citrulline for treatment of sickle cell crisis

This invention provides methods for treating endothelial dysfunction by administering an effective amount of citrulline to a patient. The patients may be suffering from acute respiratory distress syndrome (ARDS), sepsis, or infection by COVID-19 (Coronavirus Disease 2019); COVID-19 patients may be at risk of developing endothelial dysfunction, or they may be experiencing endothelial dysfunction. The effective amount of citrulline is sufficient to reduce the uncoupling of endothelial nitric oxide synthase (eNOS) or to reduce the formation of free radicals. Citrulline may be administered orally; intravenously; or both orally and intravenously in a sequential manner. Sequential administration of citrulline may be in three phases, such as (a) an initial phase in which citrulline is administered orally, (b) an intermediate phase wherein citrulline is administered intravenously, and (c) a final phase wherein citrulline is administered orally. The intermediate phase may be while the patient's breathing is being assisted mechanically.

Action of L-citrulline to prevent or treat endothelial dysfunction

The present invention provides compositions and methods of treating hyperphenylalaninemia (e.g., phenylketonuria) in a subject in need thereof comprising administering to the subject an effective amount of a phenylalanine dehydrogenase (PheDH) polypeptide. The present invention also provides pharmaceutical formulations comprising PheDH for lowering the phenylalanine concentration in the subject (e.g., in the intestines and/or blood).

Methods and compositions for treating phenylketonuria

The present disclosure relates to a biosensor capable of measuring the total concentration of one or a plurality of ammonia or ammonium ions with the use of indophenol reagents in the presence of an ionomer. In some embodiments, the biosensor comprises a perfluorinated membrane that comprises an ionomer in contact with an alkali buffer in a vessel configured to receive a sample, such as whole blood. The disclosure also relates to a method of detecting or quantifying the ammonia or ammonium ion concentration in whole blood in a point of care bio sensor without reliance on gas chromatography or any measurement that takes more than about twenty minutes.

Device and methods of using device for detection of hyperammonemia

The present disclosure relates to a biosensor capable of measuring the total concentration of one or a plurality of ammonia or ammonium ions with the use of indophenol reagents in the presence of an ionomer. In some embodiments, the biosensor comprises a perflurinated membrane that comprises an ionomer in contact with an alkali buffer in a vessel configured to receive a sample, such as whole blood. The disclosure also relates to a method of detecting or quantifying the ammonia or ammonium ion concentration in whole blood in a point of care bio sensor without reliance on gas chromatography or any measurement that takes more than about twenty minutes.

A method for administering citrulline to a patient during surgery without filtration of the hemolysis.

Intravenous administration of citrulline during surgery

Methods and compositions for treating a complication associated with aneurysmal subarachnoid hemorrhage (SAH), the method comprising administering an effective amount of a nitric oxide precursor to a subject in need thereof. Methods and compositions for treating vasospasm, the method comprising administering an effective amount of a nitric oxide precursor to a subject in need thereof.

Methods and compositions for treatment for coronary and arterial aneurysmal subarachnoid hemorrhage

The present invention relates to a biosensor capable of measuring the total concentration of one or a plurality of amino acids with the use of a reagentless system comprising an electrode modified by hydrogel that comprises at least one enzyme that oxidizes at least one substrate that is at least one amino acid. In some embodiments, the biosensor comprises a hydrogel comprising alginate. In some embodiments, the biosensor comprises use of a thermophilic bacterial metabolic enzyme immobilized or attached to the hydrogel.

Device and methods of using device for detection of aminoacidopathies

A method for administering citrulline to a patient during surgery without filtration of the hemolysis to reduce the uncoupling of eNOS enzyme dimer that leads to cardiopulmonary bypass-induced pulmonary injury.

Sequelae of cardiopulmonary bypass-induced pulmonary injury

An image analysis device includes circuitry that receives one or more input images and detects a plurality of anatomical landmarks on the one or more input images using a pre-determined face model. The circuitry extracts a plurality of geometric and local texture features based on the plurality of anatomical landmarks. The circuitry selects one or more condition-specific features from the plurality of geometric and local texture features. The circuitry classifies the one or more input images into one or more conditions based on the one or more condition-specific features.

Device and method for classifying a condition based on image analysis

The present disclosure relates to a bio-sensor capable of measuring the total concentration of one or a plurality of ammonia or ammonium ions with the use of indophenol reagents in the presence of an ionomer. In some embodiments, the biosensor comprises a perflurinated membrane that comprises an ionomer in contact with an alkaline buffer in a vessel configured to receive a sample, such as whole blood. The disclosure also relates to a method of detecting or quantifying the ammonia or ammonium ion concentration in whole blood in a point of care biosensor without reliance on gas chromatography or any measurement that takes more than about twenty minutes.

Isolated polynucleotide molecules and peptides encoded by these molecules are used in the analysis of human carbamyl phosphate synthetase I phenotypes, as well as in diagnostic and therapeutic applications, relating to a human carbamyl phosphate synthetase I polymorphism. By analyzing genomic DNA or amplified genomic DNA, or amplified cDNA derived from mRNA, it is possible to type a human carbamyl phosphate synthetase I with regard to the human carbamyl phosphate synthetase I polymorphism, for example, in the context of diagnosing and treating hepatic veno-occlusive disease (HVOD) associated with bone marrow transplants.
