¿Por qué se considera la temperatura un factor limitante en la tasa fotosintética?
By injecting Mesenchymal Stem Cells with ability to express high amount of Akt or protein kinase B in myocardium, researchers witnessed restored cardiac function and inhibition of ventricular remodeling. The effect was seen after two weeks of administration of cells. The culture containing hypoxic Akt-MSCs (conditioned medium) inhibits apoptosis or cell death induced due to hypoxia. Also, it triggers in vitro contraction of cardiomyocytes, the cardiac cells specifically responsible for contraction function.
The desired functional improvement can occur in short time which is less than 72 hours, the reason for which was hypothesized as paracrine action of cells. Hypothesis was proved by upregulation of genes that code for factors responsible for above mentioned effects (apoptosis and contraction). The factors are FGF-2, VEGF, HGF etc.

Answer:
It is a method of isometric muscle testing.
Explanation:
The manual muscle testing is used to determine the extension and degree of muscular weakness as a consequence of a disease, injury or disuse.
The results obtained from tests and exams provide a data planning base, so that the physician can plan a therapeutic procedure and periodic retesting for the patient.
The manual muscle testing requires no equipment other than the examiner's hands, it is highly portable and inexpensive, however this type of testing provides muscle strength data at only one point of ROM.
Answer:
The cell will shrink
Explanation:
Osmosis is the net movement of water molecules through a semipermeable membrane like the cell membrane from a region where their concentration is low to a region of high concentration. When the external solution has a higher osmotic pressure than the cell contents, then it is said to be hypertonic. The cell was placed in a hypertonic solution. The concentration gradient between the outside and the inside makes water molecules to move through the cell membrane to the external solution. This makes the cell to shrink due to loss of water.
