Rotator Cuff Tears and Stem Cells

Regenerative medicine with stem cells for rotator cuff injuries is being researched. Rotator cuff injuries are a common problem with the shoulder. The rotator cuff is a set of muscles and tendons which provide stability for the shoulder and allows extensive movement. The rotator cuff is prone to injury either through something abruptly happening or wear and tear or a combination of both. Often these injuries are difficult to heal and sometimes require surgery. In regenerative medicine, the body’s own healing potentials are attempted to be harnessed. Stem cells can grow into different types of cells. Researchers at the University of Michigan analyzed the stem cells that surround the rotator cuff and found that there were markers present that were more likely to produce new fat growth instead of new muscle growth when compared to other stem cells around other muscles in the body. This sheds light on to the possibility of taking stem cells from a different part of the body and placing them near the rotator cuff to help develop stronger muscle and tendon.

Identifying higher risk prostate cancer patients

A study that was published in the January issue of Mayo Clinic proceedings indicated genetic alterations maybe used as a marker in determining higher risk prostate cancer patients. When a man is diagnosed with prostate cancer and it is felt to be lower risk, treatment decisions have to be made between them and their doctor. The publication indicated that genetic markers may be analyzed in these patients to help determine if they should be more aggressive with their treatment or not. This is good news for men’s health and working with their physician.

Elevated levels of a newly discovered molecule responsible for aging bones

As we age, our bodies increasingly produce a molecule that suppresses certain functions. As levels of this regulatory molecule rise, key signalling molecules that mediate bone growth decline. Older bodies suppress stem cell production on a molecular level, scientists report.

Researchers at the Medical College of Georgia at Augusta University have uncovered exciting evidence of systemic alterations that occur with age. Their work has revealed how bones weaken and deteriorate in the aging body. One molecule in particular – microRNA-141-3P – appears to accumulate in bone tissue over time. Scientists have found that elevated levels of microRNA-141-3P are associated with osteoporosis and assorted bone pathology. The problematic molecule inhibits the absorption of vitamin C by various bone cells. It prevents the skeleton from effectively utilizing vitamin C – slowly starving bones of a much needed nutrient. This systemic shift in nutrition limits the resources available for normal bone growth. Over time, aging bones weaken and osteoporosis can develop.

Researchers suspected that suppressing microRNA-141-3P could keep bones processing vitamin C and regenerating themselves for far longer than they would under normal aging conditions. Rodent test subjects were treated with a clinical grade inhibitor of microRNA-141-3P; the result was younger, stronger bones. Scientists theorize that a similar inhibiting medication could be used in human subjects to reverse and prevent bone deterioration. The research is compelling and paints an optimistic picture of beneficial anti-aging therapy.

Development and distribution of this drug are likely far in the future. Nevertheless, the research indicates that scientists may be able to keep bones younger, for longer. By regulating a single key component of a complex cellular network, bone aging may be prevented.

Gene mutation associated with hair loss and wrinkles

Researchers at the University of Alabama at Birmingham have been experimenting with mouse mitochondrial DNA. When they introduce a mutation into this gene sequence, mice develop hair loss and wrinkles. When this gene mutation is reversed and turned back on to normal, the mice returned to smooth skin and normal fur again. They also noticed that the mice seemed to have less energy and move more slowly. What is interesting is that these external signs of aging were able to be reversed.

Light Therapy for Skin

DaVinci Med Spa offers light therapy as a modality or as an add on to procedures. According to WebMD in an article titled Testing Potential Uses for Light Therapy, “For instance, when longer wavelength or visibly “red” light hits the skin, it nudges mitochondria (the cell’s powerhouses) to make energy more efficiently and boost production of healing anti-inflammatories or disease-fighting antioxidants.” 

Cortisone (triamcinolone) shots in arthritic knees or PRP

According to a recently published research paper by Timothy E. McAlindon, DM, MPH, et al, “Among patients with symptomatic knee osteoarthritis, intra-articular triamcinolone, compared with intra-articular saline, increased cartilage volume loss and had no effect on knee pain over 2 years.” This report was published in The Journal of the American Medical Association in May of 2017. 140 patients with symptomatic arthritis were entered into the study. Half got a cortisone shot every 3 months while the other half got saline (placebo) shots in their knee. Those that got cortisone shots resulted in significantly greater cartilage volume loss than did saline patients. In other words they lost cartilage with steroid shots and did no better as far as pain.

Dr AJ Cummings has been using Platelet Rich Plasma (PRP) instead of cortisone shots on his patients for years now.
