Provided are methods and compositions for promoting cellular metabolism and cellular repair in a tissue of a subject in need thereof. The composition includes at least one N-methyl-D-aspartate receptor (NMDAR) modulator to modulate metabolic activity in cells and at least one nuclear factor erythroid 2-related factor 2 (NRF2) modulator to modulate repair activity in cells. Optionally, the composition also includes at least one inactive component and at last one microbial modulator. The composition synergistically modulates a positive-feedback signal-amplification cycle comprising NMDAR and NRF2 in cells, which, in turn, promotes cellular metabolic fitness (CMF) in a tissue of a subject in need thereof.

Provided is a pharmaceutical agent for effective prophylaxis and/or treatment of a pathological condition with decreased lung compliance. The pharmaceutical agent for prophylaxis and/or treatment of a pathological condition with decreased lung compliance is characterized by having a polyamine. The polyamine includes at least one of spermine (Spm), spermidine (Spd), and putrescine (Put). The pharmaceutical agent improves lung compliance and ameliorates gas exchange dysfunction, and therefore, can ameliorate pathological conditions such as acute respiratory distress syndrome (ARDS), acute lung injury (ALI), lung diseases caused by dysfunctional endogenous pulmonary alveolar surfactant, multiple organ dysfunction syndrome (MODS), and cardiogenic pulmonary edema.

Disclosed is use of a composition for preventing and/or eliminating platelet aggregation in an in vitro blood sample. The composition comprises at least one compound selected from the group consisting of formula, R1-NH—R2, and a salt thereof. Also disclosed is an agent, which comprises the compound for reducing platelet aggregation interference in an in vitro blood test, and a method for preventing and/or eliminating platelet aggregation in a sample in an in vitro blood test. The compound of the present invention exhibits a disaggregation effect in multiple types of platelet aggregation circumstances, and the platelet disaggregation takes effect within a short time without additional conditions such as temperature control with water bath, prolonged reaction time and the like, thereby eliminating platelet aggregation in a sample conveniently and thus accurate blood cell detection parameters can be obtained.

The nutritional food product compositions disclosed herein are provided to increase the levels of bioavailable spermidine. The compositions may include naturally-sourced spermidine in the form of a spermidine-containing fruit, vegetable, legume, and/or grain, one or more components that indirectly provides increased spermidine content, and a supplemental amount of spermidine. The compositions result in an improved profile panel of traditional biomarkers of general health and cellular health, higher levels of energy and alertness, reduced inflammation, and a stronger immune system.
