LONG-TERM USE OF GLUCOCORTICOID MODULATED PARATHYROID HORMONE LEVELS IN OSTEOPOROSIS PATIENTS.

Glucocorticoids are drugs that are often used in both inpatient and outpatient settings. Their anti-inflammatory action is often utilized to treat a variety of diseases. A range of undesirable outcomes might occur with long-term glucocorticoid use, particularly long-term high-dose applications.

Progress in biomechanical stimuli on the cell-encapsulated hydrogels for cartilage tissue regeneration.

Background: Worldwide, many people suffer from knee injuries and articular cartilage damage every year, which causes pain and reduces productivity, life quality, and daily routines. Medication is currently primarily used to relieve symptoms and not to ameliorate cartilage degeneration. As the natural healing capacity of cartilage damage is limited due to a lack of vascularization, common surgical methods are used to repair cartilage tissue, but they cannot prevent massive damage followed by injury.

Engineered substrates incapable of induction of chondrogenic differentiation compared to the chondrocyte imprinted substrates.

It is well established that surface topography can affect cell functions. However, finding a reproducible and reliable method for regulating stem cell behavior is still under investigation. It has been shown that cell imprinted substrates contain micro- and nanoscale structures of the cell membrane that serve as hierarchical substrates, can successfully alter stem cell fate.

Cell encapsulation in alginate-based microgels using droplet microfluidics; a review on gelation methods and applications.

Cell encapsulation within the microspheres using a semi-permeable polymer allows the two-way transfer of molecules such as oxygen, nutrients, and growth factors. The main advantages of cell encapsulation technology include controlling the problems involved in transplanting rejection in tissue engineering applications and reducing the long-term need for immunosuppressive drugs following organ transplantation to eliminate the side effects. Cell-laden microgels can also be used in 3D cell cultures, wound healing, and cancerous clusters for drug testing.
