Type 1 Diabetes Cure Is Closer
Diabetes is a common disease. But while type 2 depends on lifestyle habits, type 1 diabetes occurs because of a problem in the body, where the pancreas stops producing insulin completely, and it is not possible to metabolize blood sugar. This usually happens because the body attacks the beta cells of this organ, responsible precisely for the production of this hormone. It usually manifests in childhood and adolescence, while type 2 diabetes is more common in adulthood.
However, this chronic disease is a little closer to being cured. Scientists at Harvard and the Massachusetts Institute of Technology (MIT) have successfully transplanted stem cells into mice, which have been converted into insulin-producing cells and sensitive to blood glucose levels. To prevent the immune system from also attacking these cells again, they developed a material using modified alginate, a compound derived from brown algae, which encapsulates cells.
Thereafter, the researchers used encapsulated human stem cells and implanted them in lab rats. After the procedure, rats immediately began producing insulin in response to blood sugar levels. With the encapsulation of the cells, the immune system of the mice did not respond to the new cells, guaranteeing the success of the experiment.
The next step is to replicate this process in humans to arrive at a new type of therapy against type 1 diabetes.
Obesity brings several health hazards, including hindering arterial, venous and lymphatic circulation. The arterial circulation, just to remember, takes blood from the heart to the extremities, blood rich in oxygen and foods essential for the nutrition of tissues. The venous circulation receives this poor blood in oxygen and nutrients and takes it back to the lung to be oxygenated.
Voice production depends on four components: airflow from the lungs, sound production from the vocal folds (correct name for the vocal chords) in the larynx (neck region), resonance and articulation of sound in speech in throat structures (pharynx, nasal and oral cavities), and general control by the central nervous system.
