REGENERATION OF INJURED KNEES — WITHOUT SURGERY If you’re reluctant to go under the knife even
though you have a serious knee injury, you may be a candidate for a relatively new, noninvasive remedy: a stem cell therapy procedure, done on an outpatient basis, in which stem cells from your own body, usually your bone marrow, are harvest- ed and injected into an injured knee to repair dam- age from osteoarthritis, meniscus tears, and other injuries — all in 45 minutes. “Stem cells are precursor cells for every kind of
cell in the body and what they can do is very powerful,” says Laith Jazrawi, M.D., an ortho- pedic surgeon and chief of the division of sports medicine at the NYU Langone Medical Center. Besides having the ability to
transform into other types of cells, stem cells release substanc- es that stop pain and infl amma- tion and promote a healing envi- ronment in an injured area. “What we’re doing is harness-
the other fi ve days (what’s often referred to as the 5:2 plan) to going for extended periods of time without eating. By contrast, time-restricted feed- ing means limiting your eating to an eight-hour period each day. What makes these short-term forms of fasting

ing a patient’s own healing abili- ties to augment the lifespan of the knee,” Dr. Jazrawi explains. Noticeable diff er- ences in pain, mobility, and functionality typically occur in six to 12 weeks.
IMPROVING HEALTH AND LONGEVITY WITH INTERMITTENT FASTING The anti-aging benefi ts of periodic fasting have
been touted for decades, based on research in animals. More recently, studies in humans have found that both intermittent fasting and time-re- stricted feeding can lead to profound health ben- efi ts, including weight loss and reductions in risk factors for diabetes, cardiovascular disease, and other life-threatening conditions. What’s more, research from the National Insti-
tute on Aging suggests that alternating between periods of fasting and/or exercise and eating/rest- ing may optimize brain function and resilience throughout the lifespan. Intermittent fasting can range from reducing
your calorie intake to 60 percent of your usual amount two days per week and eating normally

restricted feeding improve glucose regulation and increase insulin sensitivity, eff ects that are expect- ed to protect against diabetes, explains Mark P. Mattson, Ph.D., chief of the Laboratory of Neuro- sciences at the National Institute on Aging in Baltimore. In addition, these eating pat-
terns reduce infl ammation and blood pressure, improve choles- terol and triglyceride profi les, and lead to selective loss of abdominal fat while preserving muscle mass. They also increase “cellular

stress resistance and the num- ber of healthy mitochondria [the cells’ energy factories], enhance clearance of molecular garbage from cells, and enhance the abil- ity of cells to repair damaged mol-
ecules,” Mattson explains. “In the brain, they lead to enhanced production
of neurotrophic factors, proteins that promote the formation of new synapses and the stability of ex- isting synapses.”
A CURE FOR HEPATITIS C Several new oral treatments for hepatitis C have
recently become available — and they have cure rates of 90 percent or higher with minimal side ef- fects. “In the past, we had drugs that provided a gen-
eral boost to the immune system to fi ght the infec- tion. These had success rates around 40 percent,” explains Carlos Romero-Marrero, M.D., a staff physician in the department of gastroenterology and hepatology at the Cleveland Clinic. “These new agents directly act on the hepatitis
C virus, essentially preventing it from replicat- ing.” After eight to 12 weeks of treatment, “there’s almost no detectable virus in the body — it’s quite remarkable,” Dr. Romero-Marrero says.
