The present invention provides for systems and methods for inhaled CO therapy to prevent, attenuate, or delay processes that accelerate the loss of organ or tissue function, thereby increasing the lifespan of transplanted organs or tissues, or slowing the decline of native organs or tissues, or delaying the need for replacement of diseased native organs with organ transplants. Such biological processes that are prevented, attenuated, or delayed include chronic persistent inflammation, fibrosis, scarring, as well as immunologic or autoimmune attack.

Dysglycemia as a risk factor for neurodevelopmental disorder or developmental diabetes. The risk is assessed based on measurement of a glucose control indicator in a blood sample. One particular example of a neurodevelopmental disorder is retinopathy of prematurity in an infant. One particular example of a glucose control indicator is ‘comprehensive glycated hemoglobin fraction’ or ‘comprehensive glycated albumin fraction.’ This is calculated using ‘total whole blood protein’ in the denominator. In the case of chronic hyperglycemia, there is an increased risk of proliferative retinopathy of prematurity. In the case of chronic hypoglycemia, there is an increased risk of non-proliferative retinopathy of prematurity. This ‘total whole blood protein’ technique could also be used to determine the glucose control status in other types of patients.

Provided is a method of using an aptamer for detecting a glycated hemoglobin in a whole blood, the method includes that the aptamer is provided, the aptamer includes a DNA sequence selected from the group consisting of derived sequences of SEQ ID NOs: 1, 2, 3, and 4, in which the derived sequences refer to that 3′ end and/or 5′ end of the derived sequences are modified, and the derived sequences have 90% identity to the SEQ ID NOs: 1, 2, 3, and 4. The aptamer and the whole blood are contacted. A concentration of a conjugate of the aptamer and the glycated hemoglobin is estimated. Provided also is a nanoelectronic aptasensor including the above aptamer.

A system for determining a concentration of hemoglobin A1C includes a first electrochemical test strip, the first electrochemical test strip providing for an HbA1C concentration; and a second electrochemical test strip, the second electrochemical test strip providing for the total amount of hemoglobin.

The treatment of diabetes mellitus with excellent hypoglycemic effect that suppresses lactic acidosis without substantially increasing the blood lactate concentration. A composition for treating diabetes mellitus with hypoglycemic effect that suppresses lactic acidosis without substantially increasing the blood lactate concentration, and the composition has branched-chain amino acids and salts of biguanide derivatives and derivatives of biguanide derivatives or branched-chain amino acids as the active components. The composition will be more effective when leucine, isoleucine, or valine is included as branched-chain amino acids, and metformin as the biguanide derivative.
