Regular Exercise Key to Slow Down Aging by Affecting Telomeres Length

In a new research finding by the scientists at Brigham Young University, based in Utah, we may have found the key to slow down the aging process. The scientists in the study, published in the journal Preventive Medicine, in May, 2017 have revealed that the secret to cell-based aging is coded in the tiny bits of our DNA. These tips found on the ends of our chromosome are called telomeres and their length get shortened each time the cells replicate, making you older.

Startling as it may seem, the aging can be reversed by keeping yourself physically active with regular and consistent levels of exercise. While a variety of factors, including lifestyle changes, influence the length of the telomeres in your chromosome, exercise seems to be easiest way to reverse aging.

Longer Telomere Signals Clear Advantage in Aging

The finding underlies the observation the researchers made by correlating the telomere length with the aging process among a number of people with varying levels of physical activity. Larry Tucker, one of the researchers, and a professor specializing in the exercise sciences, observed that people with elevated physical activity levels possess telomeres of nine years younger compared to those who are sedentary. Furthermore, these adults have telomeres with biological age of seven years younger than people who exercise only moderately. Tucker revealed that the telomeres of least length were observed in the sedentary people.

The data were gleaned through by observing the physical activity of 5,823 adults who may have engaged in 62 activities over a 30-day duration. The subjects had participated in the National Health and Nutrition Examination Survey (NHANES), a unique survey by the Centers for Disease Control and Prevention.

Moderate Activity May Not Make Any Difference

Surprisingly, the revelation that may alert many is that there isn’t any marked difference in the telomere length between those with low level of physical activity and those with sedentary lifestyle. So the writing on the wall is clear—low or moderate physical activities is equivalent to none. So then, what constitutes the right amount of exercise: For women, they need to sweat it out with at least 30 minutes of cardiovascular exercises and men need to exercise for at least 40 minutes for five days a week to keep themselves active.

While it’s still not clear about the exact mechanism by which exercise affects the length of telomeres in adults, Tucker opines that regular physical activity suppresses inflammation and oxidative stresses—factors closely linked to the telomeres length.

Government Funding Backs Development of Urgent Care Centers

San Francisco, California, May 15, 2017: The rapidly growing global geriatric population and soaring demand for cost-effective healthcare services have supported the establishment of urgent care centers across the globe. There are various other factors that are impacting the growth of the global market for urgent care centers, which have been covered in detail in a report by TMR Research, titled “Urgent Care Centers Market – Global Industry Analysis, Size, Share, Trends, Analysis, Growth, and Forecast 2017–2025.” The report is a professional study encompassing all the important aspects of the market.

Patients with chronic diseases such as cancer and cardiovascular disorders require timely monitoring and laboratory tests. Therefore, the rising prevalence of chronic diseases is one of the primary factors augmenting the global urgent care centers market. The growing investment from several governments and private bodies in urgent care centers are also working in favor of the market. Moreover, the merits offered by urgent care centers such as quick services and appointment flexibility is causing a shift in consumer preference from big corporate hospitals to these centers, which has a major impact on the market. The growth of the market is, however, hampered by the dearth of qualified healthcare providers and the high capital involved in the establishment of these centers.

North America and Europe, which are home to some of the major developed countries, account for a substantial cumulative share in the global arena. The U.S. is at the forefront of the growth of North America, due to growing number of urgent care centers in the country coupled with the growing preference for these centers in case of non-emergency health-related conditions. The burgeoning demand for cost-effective healthcare services is also supplementing the growth of the region.

On the basis of services, the global urgent care centers market can be segmented into illness, physical, diagnostics, injuries, screening, and vaccination. In terms of geography, Asia Pacific is expected to progress at a promising pace over the forthcoming years. Countries such as China, India, Australia, Japan, and New Zealand are the sights of high growth rate in the region, primarily owing to a widening base of population that is cost-conscious and is rapidly aging.

The global urgent care centers market is highly fragmented in nature, with private physician offices and physician groups representing a significant chunk in the overall marketplace. Some of the prominent companies operating in the market are Patient First, MD Now, CareSpot Express Healthcare LLC, FastMed Urgent Care, MinuteClinic LLC, MedExpress U.S., AFC/Doctors Express, NextCare Concentra Inc., Urgent Care, and HealthWorks Inc.

Untapped Medical Needs to Drive Retinitis Pigmentosa Market towards Growth

San Francisco, California, May 15, 2017: Retinitis pigmentosa is a medical condition inherited, which causes retinal degeneration. Since there are no treatments available for curing retinitis pigmentosa, they are much awaited and a great potential lies for new players venturing in the market. TMR Research in its latest report, studies the global business process as a service market. The report is titled “Retinitis Pigmentosa (RP) Market – Global Industry Analysis, Size, Share, Growth, Trends and Forecast 2017 – 2025.”

According to the report, the untapped medical needs for patients suffering from retinitis pigmentosa are making it a highly competitive arena and this will drive players and researchers into extensive investments and studies. In the past, several attempts have been made to slow down the degeneration process of the retina by consuming the supplement of 15,000 I.U. of Vitamin A or by consuming fish oil. However, the actual treatment is yet to be discovered, creating opportunities of growth in the market.

The report is an extensive overview of the retinitis pigmentosa market, describing this medical condition, its causes, and attempts to control the degeneration. It discusses in detail, the factors contributing to the growth of the market and those factors that act as a challenge and hampers any further growth of the market. The impact analysis of both driving and challenging factors is included in the report. Also given, is a brief history of all the key players operating in the global retinitis pigmentosa market.

The global retinitis pigmentosa market is treading towards growth in a slow manner owing to the unavailability of therapeutics to cure this rare disease. However, this has also opened doors of opportunity for players, as they take up the challenge to fight this medical condition and come up with effective cure and treatment. People afflicted with generic disorders are not receiving proper treatment due to a lack of proper cure and this is resulting in retinitis pigmentosa. Thus, there is a high demand for therapeutics that can restore vision. The approval of Argus II retinal prosthesis system by the FDA is creating a hope for patients, as it enhances a person’s ability to see and recognize movement and images.

Another new approach by the name of optogenetics is being implemented and further researched upon, by companies from the ophthalmology market. This new approach makes use of gene therapy for restoring lost sight. Such positive developments are expected to boost the confidence of players in the market and encourage them to further their efforts in researching and developing effective treatment options. Leading players operating in the market include: ReGenX Biosciences, LLC, ReNeuron Group plc, Ocugen, Inc., Orphagen Pharmaceuticals, Inc., Sucampo Pharmaceuticals, Okuvision GmbH, and Amarantus BioScience Holdings, Inc.

Human Body to be Source of Energy for New Implantable Medical Devices

Researchers from the University of Connecticut and UCLA have developed a novel bio-friendly energy storage system. It is called supercapacitor and it operates using charged ions or particles from fluids present in a human body. This device, as per researchers, will pose no threat to the body’s biological systems, and it could results in longer-lasting pacemakers for cardiac patients and other implantable medical devices.

The team of researchers from UCLA was led by Richard Kaner, who is a distinguished professor of material science and engineering, and chemistry and biochemistry. The team from Connecticut on the other hand was led by James Rusling, who is a professor of cell biology and chemistry. The paper on their novel design was published earlier this week in the journal of Advanced Energy Materials.

What is the Inspiration behind the Research?

Implantable devices such as pacemakers, which help in regulating abnormal heart rhythms and others have provided a new lease of life to millions around the world over the last few years. However, a majority of these devices are powered using traditional batteries, which eventually give up on running out power and are replaced, which means another painful surgery for the patient, besides the associated risk of infection. Moreover, these batteries contain toxic material, which could endanger a patient’s life if it leaks.

Alternate Method of Generating Energy from Human Body Proposed by Researchers

The researchers therefore proposed an alternate method of enabling these devices get the required energy. The supercapacitors invested by them are charged using electrolytes, which are collected from biological fluids such as urine and blood serum. These capacitors will also work with an energy harvester, which will convert heat and motion generated from a human body into electricity. Combining supercapacitors with energy harvesters will provide endless power to keep an implantable device running for a lifetime. With the novel technology, the need to replace implantable device will perhaps get eliminated in the future.
