What is cell nuclear transfer? A cell nucleus transfer (synonym: cell nucleus transplantation) is the insertion of a cell nucleus into a nucleusless egg cell. This was artificially produced in advance, for example by using UV radiation. The egg cell, which now contains the nucleus, can then be inserted into a sexually mature individual and … What is cell nuclear transfer? | The cell nucleus
Introduction Most of the body’s tissues renew themselves continuously. This renewal is achieved by a constant formation of new cells. This new formation is achieved by a division of cells. This cell division requires that the cells are capable of dividing. The cells capable of division in adults are called adult stem cells. The actual … Cell Nuclear Division
Why does cell division occur? Nuclear division is necessary to create cells for tissues that are constantly renewing themselves. The body’s ability to function and heal is based on the fact that dead cells can be replaced by new ones. However, there are differences in the ability to divide between the different tissues.Some parts of … Why does cell division occur? | Cell Nuclear Division
How does a tumor develop? The word tumor literally means swelling and can be triggered by various processes. The most common cause of swelling is inflammation, which causes swelling due to increased water retention. A tumor caused by unchecked proliferation of cells is also called neoplasia. There are many different forms of neoplasia, which arise … How does a tumor develop? | Cell Nuclear Division
Definition – What is a Wolf-Hirschhorn Syndrome? The Wolf-Hirschhorn syndrome describes a complex of different malformations, which are caused by a change in the chromosomes (chromosomal aberration). The malformations include above all changes in the head, brain and heart. The Wolf-Hirschhorn syndrome occurs in about 1:50. 000 children. It affects girls more frequently than boys … Wolf-Hirschhorn Syndrome
TreatmentTherapy The Wolf-Hirschhorn-Syndrome is not curable. A purely symptomatic therapy is carried out with the aim of improving the quality of life of those affected. This includes various forms of therapy such as occupational therapy, physiotherapy, speech therapy and surgical correction of some malformations. Epilepsy should also be treated with medication. In some cases, artificial … TreatmentTherapy | Wolf-Hirschhorn Syndrome
What is the tyrosine kinase receptor? The tyrosine kinase receptor represents a membrane-bound receptor, i.e. a receptor anchored in the cell membrane. Structurally, it is a receptor with a transmembrane complex. This means that the receptor passes through the entire cell membrane and also has an extra- and intracellular side. On the extracellular side, the … What is the tyrosine kinase receptor? | The tyrosine kinase
For which indications are they used? Tyrosine kinase inhibitors are used for various malignant diseases. Imatinib is used in particular in chronic myeloid leukemia. Further applications are non-small cell lung cancer (NSCLC), breast cancer and colon cancer. Due to the highly selective attack mechanism of tyrosine kinase inhibitors, they are generally better tolerated than conventional … For which indications are they used? | The tyrosine kinase
What is a tyrosine kinase? Tyrosine kinase is a specific group of enzymes that are functionally assigned to protein kinases in a biochemical sense. Protein kinases reversibly (possibility of back-reaction) transfer phosphate groups to the OH group (hydroxy group) of the amino acid tyrosine. The phosphate group is transferred to the hydroxy group of the … The tyrosine kinase
Introduction Trypsin is an enzyme that is produced in the pancreas and is very important for the digestion of humans. It activates other digestive enzymes from the pancreas in the intestine, which in turn further break down proteins that are taken in with food. These can then be absorbed by the intestine as it continues … Trypsin
Trypsin inhibitors Trypsin inhibitors are peptides that prevent trypsin from exerting its effect in the intestine or restrict it. Trypsin is blocked and cannot fulfil its function as an activator of other digestive enzymes in the intestine. Trypsin inhibitors are found in various foods. A well-known representative is soybeans, which contain trypsin inhibitors in raw … Trypsin inhibitors | Trypsin
At what pH value does Trypsin work best? Trypsin, like most other digestive enzymes, can only work properly at a certain pH. The optimal pH range for trypsin is between 7 and 8, which corresponds to the pH range in the small intestine of a healthy person. If this range changes, trypsin can no longer … At what pH value does Trypsin work best? | Trypsin
