hyperimmune bovine colostrum
A dietary supplement consisting of bovine colostrum, containing high titers of immunoglobulins (Igs), with immunostimulating and anti-infective activities. Hyperimmune bovine colostrum is harvested during the first days after calving from cows that have been inoculated repeatedly with specific pathogens during pregnancy. In addition to high titers of anti-pathogen specific antibodies, hyperimmune colostrum is also rich in other immune factors, proline-rich polypeptides (PRP), lactoferrin, glycoproteins, lactalbumins, cytokines, growth factors, vitamins, and minerals. This dietary supplement may exhbit anti-infective activity in immunocompromised patients. Check for active clinical trials using this agent. (NCI Thesaurus)
hyperpolarized helium 3
A contrast agent composed of hyperpolarized helium He 3 gas (HP3He), with potential usage in diagnostic nuclear magnetic resonance (NMR)-based imaging (MRI). Upon inhalation, the hyperpolarized helium He 3 gas is distributed throughout the lungs. MRI, immediately following HP3He administration, allows for the visualization of lung structures based on the distribution pattern of the gas. This may aid in the diagnosis of certain lung abnormalities. Hyperpolarization of He 3 enhances NMR signals and thus improves imaging and assessment of lung function. Check for active clinical trials using this agent. (NCI Thesaurus)
hyperpolarized xenon 129
A contrast agent composed of hyperpolarized xenon Xe 129 gas (HP129Xe), with potential usage in diagnostic nuclear magnetic resonance (NMR)-based imaging (MRI). Upon inhalation, the hyperpolarized xenon 129 gas is distributed throughout the lungs. MRI, immediately following HP129Xe administration, allows for the visualization of lung structures based on the distribution pattern of the gas. This may aid in the diagnosis of certain lung abnormalities. Hyperpolarization of Xe 129 enhances NMR signals and thus improves imaging and assessment of lung function. Check for active clinical trials using this agent. (NCI Thesaurus)
hypertonic saline
Any solution of sodium chloride (NaCl) in water with a concentration of NaCl higher than that found in physiological saline (0.9% w/v). When administered in vivo, hypertonic saline (HTS) exhbits several physiological effects beneficial to cerebral injury including: 1) osmotic and vasoregulatory - by promoting the flow of excess water from cerebral tissue to the blood via osmosis and decreasing edema in the vascular endothelium of injured tissues, thus lowering vascular resistance and allowing more blood flow; 2) hemodymanic - by effectively expanding plasma volume; 3) immunomodulatory - by preventing leukocytes from becoming activated and adhering to injured neurons and; 4) neurochemical - by counteracting detrimental excitatory amino acids through the normalization of neuronal cell membranes and by restoration of normal electrolyte and neurotransmitter levels in brain cells, and normal cell volumes. Check for active clinical trials using this agent. (NCI Thesaurus)
hypoxia-activated prodrug TH-4000
A proprietary, hypoxia-activated prodrug with potential antineoplastic activity. Upon administration, the hypoxia-activated prodrug TH-4000 is activated in the hypoxic cells within tumors into an irreversible pan-HER inhibitor via a mechanism of action not yet fully elucidated. As a result, this agent inhibits cellular proliferation and differentiation of tumor cells overexpressing HER kinases, which belong to the epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases. Healthy, normal tissues may be spared due to the hypoxia-specific activity of this agent, potentially reducing systemic toxicity. Check for active clinical trials using this agent. (NCI Thesaurus)
Hypoxin
(Other name for: hypoxia-activated prodrug TH-4000)
Hytone
(Other name for: therapeutic hydrocortisone)
