28 results about "Hemoglobin" patented technology

Hemoglobin (American English) or haemoglobin (British English) (/ˈhiːməˌɡloʊbɪn, ˈhɛ-, -moʊ-/), abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein in the red blood cells (erythrocytes) of almost all vertebrates (the exception being the fish family Channichthyidae) as well as the tissues of some invertebrates. Hemoglobin in blood carries oxygen from the lungs or gills to the rest of the body (i.e. the tissues). There it releases the oxygen to permit aerobic respiration to provide energy to power the functions of the organism in the process called metabolism. A healthy individual has 12 to 20 grams of hemoglobin in every 100 ml of blood.

Application of huperzine A in treatment of beta-thalassemia

The invention relates to the technical field of medicines, in particular to application of huperzine A in treatment of beta-thalassemia. It is found for the first time that the anti-Alzheimer disease drug huperzine A can be directly combined with gamma-globin to inhibit degradation of gamma-globin through a ubiquitin-proteasome pathway, so that the stability of gamma-globin and the fetal hemoglobin level are improved; the abnormal erythropoiesis and hemolysis phenotype of the beta-thalassemia are improved under the condition of not changing the mRNA expression. Animal experiments show that huperzine A obviously improves hematocrit and the number of red blood cells, reduces the size distribution width of the red blood cells and the proportion of reticulocytes, relieves oxidative stress, hemolysis, splenomegaly and iron overload, and has no obvious liver and kidney toxicity. The invention creatively provides a new strategy for improving HbF by regulating and controlling protein homeostasis instead of transcriptional up-regulation, and provides a new drug action mechanism and application direction for treatment of beta-thalassemia and other hemoglobin diseases.

Use of composition comprising TET pathway inhibitor and ferroptosis inducer in manufacture of medicament for treatment of malignant tumors

Disclosed is the use of a composition comprising a TET pathway inhibitor and a ferroptosis inducer in the manufacture of a medicament for the treatment of malignant tumors. It is found that TET1 up-regulates expression of a ferroptosis key regulation gene GCH1 through an NF [kappa] B signal, promotes synthesis of BH4, activates a GPX4 non-dependent pathway, and plays a key hub role in controlling ferroptosis sensitivity. Through combined use of TET pathway inhibitors (including a TET inhibitor and a BH4 synthesis inhibitor), the sensitivity of tumor cells to the ferroptosis inducer can be significantly improved, and the in-vivo use dosage of the ferroptosis inducer is reduced to 1% (1 mg / kg) of the conventional treatment dosage. The composition of the TET pathway inhibitor and the ferroptosis inducer, provided by the invention, can be used for remarkably improving the ferroptosis induction curative effect of various malignant tumors, particularly ferroptosis insensitive tumors, and enhancing the safety and universality of ferroptosis induction treatment.

Infusion of nitrite iv caused an acute drop in resting energy expenditure (oxygen consumption) and nitrate, when given perorally, caused a reduction in oxygen consumption during exercise and a depression of the increase in blood glucose observed after an oral glucose tolerance test. The doses of nitrate and nitrite did not cause any detectable change in methemoglobin levels of blood. Also, nitrate and nitrite did not alter lactate levels in blood. This discovery provides useful treatments to regulate the energy expenditure and glucose homeostasis of a mammal by administration of inorganic nitrite and / or nitrate.
