Were living longer these days, but that hasnt stopped newer branches of medicine from trying to enhance and further extend our lifespans.

Researchers in longevity medicine and biogerontology are studying drugs and compounds that can prevent and reverse aging on the cellular level.

Over the past few years, public interest in longevity issues has grown, but that interest is mostly in health-extending therapies, not simply life-extending therapies. Most people are interested in living longer, but only if they can also be healthier longer, Sonia Arrison, author of 100 Plus: How the Coming Age of Longevity Will Change Everything, From Careers and Relationships to Family and Faith, and founder of Singularity University in California, told Healthline.

While many people are focused on lifestyle changes, the addition of drugs rapamycin and metformin are two that Arrison mentioned gives humans more options to extend their lives as well as the quality of their lives.

Compared with preventative drugs such as statins to avoid having a heart attack, anti-aging drugs fight multiple diseases at once instead of focusing on one ailment, Arrison added.

A person who goes by the name Reason, a technologist and author on FightAging.org, which highlights health- and longevity-enhancing medical technologies, told Healthline that the drugs are targeting a wide range of age-related ailments and diseases.

All age-related diseases are age-related because they are caused by the processes of aging, which is to say an accumulation of damage in cells and tissues, Reason wrote in an email.

The field of geroprotection involves understanding cell senescence, which is when cells stop dividing.

When senescent cells no longer divide, they stop functioning, so organ health deteriorates. Cell senescence also causes the release of proinflammatory cytokines, which damage tissues.

This arena involves the use of geroprotectors, which are compounds that can stop or reverse cellular aging, and senolytics, which are compounds that can pinpoint and destroy senescent cells.

This is why researchers are looking into geroprotectors and senolytics, which requires long spans of time to understand.

In essence, todays researchers may never see the outcomes of the research theyve started because it can take decades to study. Nevertheless, scientists continue to try to understand these compounds and how they can alter our cells.

Researchers are also looking into our cells telomeres, which are short segments of DNA in our chromosomes that protect cells from wear and tear that comes with aging. As cells divide, they can shorten and no longer protect the chromosome or cell.

Lengthening them is the focus of recent research. Last year, a BGRF study was able to lengthen human telomeres.

A recent report in the journal Cell detailed how peptides were able to boost the life span of mice. The study examined how cell therapy could reverse poor age-related kidney function, fur loss, and frailty in mice.

Scientists are looking into whether or not the approach can also prolong the life span of mice. Human safety studies are in the works.

Reason said there are two schools of thought when exploring extending life through genetic pathways.

One approach is to alter cellular metabolism and make cells age more slowly, but the work is difficult and expensive. The other is to fix old tissue because we understand how it compares with young tissue.

No one yet fully understands everything these [older] cells do to us, but the fastest way to find out is to get rid of them, and we know that doing that in mice extends life and reverts aspects of aging, Reason explained.

Either you slow down the damage, or you repair the damage. Aging is damage. It is in the how of achieving one of those goals that all the complexity starts up, Reason added.

The Human Aging Genomic Resources (HAGR) website recently released DrugAge, a database of lifespan-extending drugs and compounds.

It includes 418 compounds that were recorded from studies on 27 different model organisms.

HAGR already operates the GenAge database of age and longevity-related genes in humans and model organisms. They also operate AnAge, which has aging and longevity records of more than 4,000 species, the GenDR database of genes associated with the life-extending effects of dietary restriction, and LongevityMap, which includes more than 2,000 human gene and genetic variations linked to longevity.

DrugAge incorporates earlier efforts by Biogerontology Research Foundation (BGRF) scientists, who produced Geroprotectors.org. Right now, its the largest database of its kind.

According to the research teams from BGRF and the University of Liverpool, pharmaceuticals have not targeted most age-related pathways. The research is only focused on a small number of pathways that are currently known.

The goal behind the database is to pave the way for discovery of new life span-extending and health span-extending compounds.

I am confident that it [DrugAge] will gain widespread use in the aging research community, and represents a significant milestone along the way to the coming paradigm shift in modern healthcare away from single disease treatment and toward geroprotective multi-disease prevention, Dmitry Kaminskiy, managing trustee of BGRF, said in a statement.

Franco Cortese, deputy director and trustee of BGRF, said in a statement the database will be extremely valuable for biogerontologists. The BGRF did not respond to Healthlines request for comment.

Already, researchers are using the data to identify trends and develop a better understanding of the comparative effects of geroprotectors on organisms.

Arrison is excited when she sees people teaming up globally to battle human disease and decline something that the DrugAge team is hoping to do with their database.

The more knowledge the health community can get, the better. The wonderful thing about the internet is that knowledge gets distributed faster, making the quest for cures that much quicker, Arrison added.

"Our publicity will show how what has become known as the 'Riobe Method' produces such results as abundant energy, strong sex drives, normal weight and significant protection from diseases such as cancer," he said.

According to Tim Allen, Vice President of Public Relations at TransMedia who'll be point person on the account, "Dr. Riobe addresses what so many patients complain about, but are not receiving effective treatments for, including such chronic conditions as fatigue, poor sleep and overweight.

"We plan to publicize how these common problems led Dr. Riobe to set out to find better alternatives and to learn methods that evaluate and treat root causes rather than mask symptoms. This calling led her to study Traditional Chinese Medicine and Holistic/Alternative Medicine includingBio-identical Hormone management."

About Dr. Riobe

Dr. Riobe completed her undergraduate studies at Columbia University/Columbia College in New York City where she grew up. She obtained her medical degree at NY Medical College and completed her residency in Obstetrics and Gynecology at Medical College of Pennsylvania and the University of South Carolina.

There she learned conventional medical practices which she practiced following her graduation and board certification in OB/GYN.

"During this time she became frustrated with what she saw as a 'cookie-cutter' approach to medicine and decided to incorporate alternative forms of medicine," Madden said.

"She found much better results when she combined traditional methods with time-tested Chinese medicine, which she incorporated into her practice and that will be the central theme of our PR campaign," he added.

Dr. Riobe's practice is located in Stuart, Florida where she treats patients while raising two children and maintaining remarkable personal fitness. She is an author and speaker at health and medical conferences nationwide. One of her books is titled "The Answer to Cancer."

More than half of family doctors in Canada are still using manual devices, a dated technology that often leads to misdiagnosis.

A study by researchers at the University of Montreal Hospital Research Centre (CRCHUM) reports that over half of the Canadian family doctors are still making use of manual devices to measure blood pressure, which is a dated technology. Using a manual device to measure blood pressure often leads to misdiagnosis. Approximately 20% of those receiving treatment for hypertension don't actually have it and do not need medication.

Automatic electronic devices, called oscillometric devices, are available and are recommended by the Guidelines of the Canadian Hypertension Education Program (CHEP) as preferable to manual measurement.

However, in the spring of 2016, the team that conducted the survey among the Canadian family doctors found that 52% of the 769 who responded stated that they made use of a manual tensiometer to measure patients' blood pressure, and only 43% used an automatic device.

The lead author of the study, Janusz Kaczorowski, is a medical sociologist, a CRCHUM researcher, and a professor in the Department of Family and Emergency Medicine.

Manual measurement is acceptable if it is done properly, but that is not always the case. Kaczorowski stated that clinicians should use automatic devices because they are more precise and take several measurements. Automated measurement has an advantage because it eliminates white-coat syndrome, which is an artificially high blood pressure reading that is a result of being in a doctor's office.

To take blood pressure properly, a 12- to 15-minute period is required with the patient being left alone in a room while the measurement is taken. That is difficult because the average visit to a family doctor lasts only 10 minutes.

Blood pressure is the pressure that the blood exerts on the walls of arteries. Measured in an artery in the arm, blood pressure has two measurements: systolic as the heart contracts and diastolic as the heart relaxes. Normal pressure has the systolic pressure at below 140 mmHg and the diastolic pressure at below 90 mmHg. Above those numbers, a person is said to have high blood pressure or hypertension.

In Canada, one of every five adults suffers from hypertension, which is the greatest global risk factor for disability and death. Healthcare costs due to hypertension were evaluated at over $13 billion in 2010. Kaczorowski says that if blood pressure was measured incorrectly, there are considerable financial implications as well as possible side effects, which could be avoided.

The CHEP Guidelines state that modification of health-related behaviors is an efficient way of treating and preventing high blood pressure and reducing the cardiovascular disease risk. It is possible to lower one's blood pressure with a healthy diet, reduced intake of sodium, regular physical activity, moderate consumption of alcohol, tobacco product avoidance, and stress management.

Regular infusions of a peptide that can selectively seek out and destroy broken-down cells that hamper proper tissue renewal, called senescent cells, showed evidence of improving healthspan in naturally-aged mice and mice genetically engineered to rapidly age. The proof-of-concept study, published March 23 in Cell, found that an anti-senescent cell therapy could reverse age-related loss of fur, poor kidney function, and frailty. It is currently being tested whether the approach also extends lifespan, and human safety studies are being planned.

The peptide took over four years of trial and error to develop and builds on nearly a decade of research investigating vulnerabilities in senescent cells as a therapeutic option to combat some aspects of aging (Trends in Molecular Medicine, 10.1016/j.molmed.2016.11.006). It works by blocking the ability of a protein implicated in senescence, FOXO4, to tell another protein, p53, not to cause the cell to self-destruct. By interfering with the FOXO4-p53 crosstalk, the peptide causes senescent cells to go through apoptosis, or cell suicide.

"Only in senescent cells does this peptide cause cell death," says senior author Peter de Keizer, a researcher of aging at Erasmus University Medical Center in the Netherlands. "We treated mice for over 10 months, giving them infusions of the peptide three times a week, and we didn't see any obvious side effects. FOXO4 is barely expressed in non-senescent cells, so that makes the peptide interesting as the FOXO4-p53 interaction is especially relevant to senescent cells, but not normal cells."

Results appeared at different times over the course of treatment. Fast-aging mice with patches of missing fur began to recover their coats after 10 days. After about three weeks, fitness benefits began to show, with older mice running double the distance of their counterparts who did not receive the peptide. A month after treatment, aged mice showed an increase in markers indicating healthy kidney function.

Senescent cell therapy is one of several strategies being tested in mice aimed at reversing aging or lengthening healthspan. In 2015, the Valter Longo laboratory at the University of Southern California reported that mice on a calorie-restricted diet that mimics fasting benefited from a longer life, a reduction in inflammatory disease, and improved memory (Cell Metabolism, 10.1016/j.cmet.2015.05.012). And last December, Juan Carlos Izpisua Belmonte at the Salk Institute of Biological Science and colleagues made headlines with their discovery that cellular reprogramming of epigenetic marks could extend lifespan and improve health in fast-aging mice (Cell, 10.1016/j.cell.2016.11.052).

"This wave of research on how we can fight aging is complementary, and not in competition," says de Keizer. "The common thread I see for the future of anti-aging research is that there are three fronts in which we can improve: The prevention of cellular damage and senescence, safe therapeutic removal of senescent cells, to stimulate stem cellsno matter the strategyto improve tissue regeneration once senescence is removed."

de Keizer aims to start a company based on these findings, but in the short term, he and his group want to show that their peptide is non-toxic in humans with no unforeseen side effects. They plan to offer a safety clinical trial in people with Glioblastoma multiforme, an aggressive brain tumor, which also shows high levels of the biomarkers needed for this FOXO4 peptide to be effective.

Question: My hormone replacement is not working; is there anything new?

Answer: Hormones affect every aspect of our lives, including general health, mood and overall well-being. The last 10 years have seen a dramatic change in attitude as to how men and women should be treated for hormonal imbalances.

While the movement toward bio-identical hormones has been appropriate from a safety standpoint, the delivery of hormones has been a source of frustration for many patients and their doctors. Because oral therapies have greater risks, patients have been encouraged to try creams, gels, injections and patches.

The issues with these delivery methods are uncontrolled fluctuations in hormone levels, poor absorption into the body, and messy and inconvenient treatment regimens. The net result is that, for many people, their symptoms are not effectively relieved, and the health benefits are not fully realized.

The answer lies in a therapy that, while popular worldwide, is only now beginning to receive the attention it deserves in the U.S. Pellet hormonal therapy seems to be the ideal solution to finding a safe, convenient, reliable and natural delivery of hormonal therapy. Pellets contain pure hormone that is not metabolized into unwanted byproducts, and allows your body to use the right amount of hormone to create better moods, vitality, and health and well-being.

New hormone treatment gaining popularity - Palm Beach Post

An anti-aging therapy could be one step closer; in a new study, researchers reveal how a peptide led to the destruction of cells that play a role in aging, reversing fur loss, kidney damage, and frailty in mice.

The research describes how the peptide stops levels of a protein called FOXO4 from increasing in senescent cells, which are cells that lose the ability to replicate and destroy themselves, but which remain metabolically active.

Senescent cells accumulate with age, and studies have shown that they can contribute to the aging process by causing damage to neighboring cells and impairing tissue function.

Previous research has shown that in senescent cells, levels of FOXO4 rise to prevent another protein called p53 from prompting the cells' self-destruction.

By blocking FOXO4 with the peptide, the research team has been able to restore programmed cell death, or apoptosis, in senescent cells.

"Only in senescent cells does this peptide cause cell death," says senior author Peter de Keizer, a researcher of aging at Erasmus University Medical Center in the Netherlands.

"FOXO4 is barely expressed in non-senescent cells, so that makes the peptide interesting, as the FOXO4-p53 interaction is especially relevant to those cells, but not normal cells."

On administering the peptide to fast-aging mice in regular doses, the researchers were able to reverse age-related conditions, such as fur loss and poor kidney health.

The findings were recently published in the journal Cell.

For their study, the researchers tested the peptide on older mice that had aged naturally and mice that had been genetically modified to age rapidly.

Both groups of mice developed characteristics and health problems commonly associated with aging, such as loss of fur, a decline in kidney health, and frailty.

Some of the rodents in each group were given infusions of the peptide three times a week for 10 months, while the remaining mice were monitored as controls.

Both the fast-aging and naturally aged mice saw improvements with peptide treatment, with no apparent side effects.

Within 10 days, the fast-aging mice began to experience fur regrowth. After 3 weeks, the naturally aged mice began to see improvements in fitness, compared with mice that did not receive the peptide.

Additionally, both the fast-aging and naturally aged mice started to demonstrate improvements in kidney function from 1 month after peptide treatment.

The team notes that the effects of peptide treatment were was so strong in fast-aging mice that doses needed to be reduced over the study period.

The researchers say that their findings support previous research showing that targeting senescent cells can help to reverse aging and increase lifespan, though much more research is warranted.

"The common thread I see for the future of anti-aging research is that there are three fronts in which we can improve: the prevention of cellular damage and senescence, safe therapeutic removal of senescent cells, to stimulate stem cells - no matter the strategy - to improve tissue regeneration once senescence is removed," says de Keizer.

He and his colleagues now plan to conduct a clinical trial to assess the safety of the peptide in humans.

Posted on March 24, 2017, 6 a.m. in Cancer Exercise

New study reveals that lactate, a molecule produced during intense exercise, plays a key role in cancer cell formation.

Medical researchers are on a quest to develop a comprehensive understanding of the mechanism that causes the process in which cells become cancerous. This process is known as oncogenesis. A recent study keys in on the molecule generated amidst intense exercise known as lactate. The purpose of this research is to explain lactate's role in the creation of cancer cells. The latest study's findings were published in the popular journal Carcinogenesis. About Lactate

Lactate is the byproduct of glycolysis, a chemical process that breaks apart sugar into smaller molecular components with the ultimate aim of generating energy. Lactate builds up in the blood and tissues when one engages in intense physical activity. If enough lactate accumulates, it can cause diminished physical performance as well as muscle tightness.

A famous German scientist named Otto Warburg first noticed that cancer cells consume an abundance of glucose compared to regular cells. Known as the Warburg effect, this phenomenon is a reference to the fact that cancer cells proceed through more glycolysis and generate more lactate than regular cells. The Latest Research

New research on this subject matter has been spearheaded by the director of the Sports Performance Department and physiology laboratory at the University of Colorado-Boulder's Sports Medicine and Performance Center. The director, Inigo San Millan, was determined to figure out why the Warburg effect occurs. Cancer research has deviated from cell metabolism study to genetics since Warburg's heyday in the early 20th century. However, the latest research might shift the spotlight back to lactate's role in the context of cancer development. Lactate and Oncogenesis

San Millan's research team suggests that lactate is the sole metabolic compound necessary and involved in the nearly half-dozen stages that stem from carcinogenesis. Their study analyzed the role of lactate in the process through which new blood vessels develop within tumors. This medical term for this process is angiogenesis. The study also examined the role of lactate in immune escape. This term refers to the cancer cells' eluding of the human body's natural immune responses. It also delves into the role of lactate in cell migration, self-sufficient metabolism, and metastasis.

San Millan's paper details how lactate assists in the creation of an acidic microenvironment outside of the cancer cell during metastasis. This phenomenon triggers the spread of additional cancer cells. The study also explores the connection between genetic components and lactate. The research team hypothesized that three transcription factors (p53, cMYC and HIF-1) common in the majority of cancers catalyze the deregulation of lactate. Can Halting Lactate Stop Cancer?

The important role of lactate in cancer cell creation helps explain why people who exercise on a regular basis have a low risk of cancer development. Individuals who exercise enjoy a body that is trained to transfer lactate to an energy source for the body, preventing an excessive accumulation of the metabolic compound. The findings allow for speculation that an idle lifestyle combined with an excessive consumption of sugar might lead to an abundance of lactate that leads to cancer. These findings show that lactate is not only present when cancer develops but required for each step of its development. What's Next?

San Millan hopes to team up with the University of Colorado Hospital to analyze the effects of custom tailored physical fitness programs created for cancer patients. At the moment, San Millan is studying the nuances of breast cancer cell lines. His hope is that additional research will ameliorate the quest to develop drugs that prevent the accumulation of lactate. These drugs will likely help key in on monocarboxylate transporters that transmit lactate between the body's cells.

Within 10 days, the fast-aging mice began to experience fur regrowth. After 3 weeks, the naturally aged mice began to see improvements in fitness, compared with mice that did not receive the peptide.

Additionally, both the fast-aging and naturally aged mice started to demonstrate improvements in kidney function from 1 month after peptide treatment.

The team notes that the effects of peptide treatment were was so strong in fast-aging mice that doses needed to be reduced over the study period.

The researchers say that their findings support previous research showing that targeting senescent cells can help to reverse aging and increase lifespan, though much more research is warranted.

"The common thread I see for the future of anti-aging research is that there are three fronts in which we can improve: the prevention of cellular damage and senescence, safe therapeutic removal of senescent cells, to stimulate stem cells - no matter the strategy - to improve tissue regeneration once senescence is removed," says de Keizer.

He and his colleagues now plan to conduct a clinical trial to assess the safety of the peptide in humans.

PureTech will take on the development of two mTORC1 inhibitors from Novartis aimed at stopping the decline of the immune system associated with age.

Novartis is building up the portfolio of PureTech is a Boston-based healthcare company listed on the London stock market. Originally an investment firm, it now has put together a drug pipeline from its biotech portfolio. Its latest additionsare twodrugs to prevent and treat diseases related toimmunosenescence, an age-related process that reduces the immune systems functions.

PureTech will create a subsidiary, resTORbio, to carry out the development, starting with a Phase IIb trial for age-related immune system deterioration. The US company has allocated 14M ($15M) for the program, giving it a 58% stake that could rise to 67% in the future with an additional 9M ($10M) investment.

For its part, Novartis will get an undisclosed equity stake in the company plus milestonepayments and royalties as the drug advances through development and commercialization. The big Swiss pharma has already run two Phase IIa studies in elderly patients with the two mTORC1 inhibitors.

The immune system progressively loses its function with age, leading to age-related disorders

Novartis already has an mTOR inhibitor in the market, Everolimus, used as an immunosuppressant for organ transplantation and certain forms of cancer. Preclinical research seemed to indicate that this drug could also extend the lifespan and boost the efficacy of vaccines, which led the company to start human trials.

However, despite the promising potential of the candidates, Novartis has decided to trust someone else with developmentand waitto see whether theyre successful in the long term.

The field ofanti-aging,focused on delaying and preventing age-related conditions, is still young and so far it mostly attracts innovative biotech companies rather than traditional pharma. But as medicine advances and the human lifespan increases, Im sure it will start gaining more and more recognition.
