How long does immunosuppression last after a transplant?
Although the complete blood count and differential may be normal, immunosuppression may last for up to a year after the transplant, along with the risk of infections. Also, the oral cavity and salivary glands are commonly involved in graft-versus-host disease in allograft recipients. This can result in mucosal inflammation, ulceration, and xerostomia, so continued monitoring is necessary. Careful attention to oral care in the immediate and long-term post-transplant period is important to patients’ overall health.
Can you use fluoride for dental demineralization?
Fluoride rinses are not adequate to prevent tooth demineralization. Instead, a high-potency fluoride gel, delivered via custom gel-applicator trays, is recommended. Several days before radiation therapy begins, patients should start a daily 10-minute application of a 1.1% neutral pH sodium fluoride gel or a 0.4% stannous fluoride (unflavored) gel. Patients with porcelain crowns or resin or glass ionomer restorations should use a neutral pH fluoride. Be sure that the trays cover all tooth structures without irritating the gingival or mucosal tissues.

What is hyperthermia therapy?
Hyperthermia Therapy is an experimental form of cancer therapy that utilizes localized or whole-body administration of heat. Intense heating will cause denaturation and coagulation of cellular proteins, rapidly killing the cells within a tumor. What this means is the protein cells will lose their quaternary structure, tertiary structure and secondary structure which causes cell disruption and cell death. A mild heat-treatment in combination of other stresses can also cause apoptosis of the cell, which means the cell dies and creates fragments which are called apoptotic bodies, which can be cleaned up by phagocytic cells. Phagocytic cells engulf these apoptotic bodies which destroys them, rendering them unable to cause damage to surrounding cells.
How do nanoparticles kill cancer cells?
Doctors would then heat these nanoparticles up using magnetic fields or radio waves, killing the surrounding cancer cells. The particles would need to heat up quickly to successfully kill the cancer cells, however, due to the tendency of the body to carry heat away from a given location.
Is quercetin good for cancer?
Quercetin is a dietary supplement that makes for an excellent free-radical-scavenging antioxidant and it also promotes apoptosis in cancerous cells. In vitro it has been proven to have anti-tumor proclivities in both oral cancer and leukemia. Cultured skin and prostate cancer cells showed significant mortality (compared to nonmalignant cells) when treated with a combination of quercetin and ultrasound. Interestingly enough, ultrasound promotes topical absorption of up to 1,000% making a topical Quercetin and ultrasound combination to be a possible option for experimental cancer treatment. Quercetin is found in most fruits, vegetables, leaves and grains, which is why a diet high in these items can be very advantageous for many cancer patients. When taken orally, such as eating products that naturally contain it, it can be a helpful supplement to other cancer treatments, but doctors are trying to find a way to create a topical ointment that will work against cancerous cells to use in combination with ultrasound therapy. The topical ointment is still in early development, but the food items that contain this antioxidant are readily available on the market.
