  • The health benefits following exercise training are elicited by gene expression changes in skeletal muscle, which are fundamental to the remodeling process
  • there is increasing evidence that more short-term environmental factors can influence DNA methylation
  • dietary factors have the potency to alter the degree of DNA methylation in different tissues, 9,10 including skeletal muscle
  • In one study, a single bout of endurance-type exercise was shown to affect methylation at a few promoter CpG sites
  • In the context of diabetes, exercise training has been shown to affect genome-wide methylation pattern in skeletal muscle,13 as well as in adipose tissue.
  • physiological stressors can indeed affect DNA methylation
  • training intervention reshapes the epigenome and induces significant changes in DNA methylation
  • the findings from this tightly controlled human study strongly suggest that the regulation and maintenance of exercise training adaptation is to a large degree associated to epigenetic changes, especially in regulatory enhancer regions
  • Endurance training [after training (T2) vs. before training (T1)] induced significant (false discovery rate, FDR< 0.05) methylation changes at 4919 sites across the genome in the trained leg
  • identified 4076 differentially expressed genes
  • a complementary approach revealed that over 600 CpG sites correlated to the increase in citrate synthase activity, an objective measure of training response (Figure S4 and Dataset S14). This might imply that some of these sites could influence the degree of training response.
  • As expected by a physiological environmental trigger on adult tissue, the observed effect size on DNA methylation was small in comparison to disease states such as cancer
  • a preferential localization outside of CpG Islands/Shelves/Shores
  • endurance training especially influences enhancers
  • negative correlation was more prominent for probes in promoter/5′UTR/1st exon regions, while gene bodies had a stronger peak of positive correlation
  • The significant changes in DNA methylation, that primarily occurred in enhancer regions, were to a large extent associated with relevant changes in gene expression
  • The main findings of this study were that 3 months of endurance training in healthy human volunteers induced significant methylation changes at almost 5000 sites across the genome and significant differential expression of approximately 4000 genes
  • DMPs that increased in methylation were mainly associated to structural remodeling of the muscle and glucose metabolism, while the DMPs with decreased methylation were associated to inflammatory/immunological processes and transcriptional regulation
  • This suggests that the changes in methylation seen with training were not a random effect across the genome but rather a controlled process that likely contributes to skeletal muscle adaptation to endurance training
  • Correlation of the changes in DNA methylation to the changes in gene expression showed that the majority of significant methylation/expression pairs were found in the groups representing either increases in expression with a concomitant decrease in methylation or vice versa
  • The fraction of genes showing both significant decrease in methylation and upregulation was 7.5% of the DEGs or 2.3% of all genes detected in muscle tissue with at least one measured DNA methylation position. Correspondingly, 7.0% of the DEGs or 2.1% of all genes showed both significant increase in methylation and downregulation
  • we show that DNA methylation changes are associated to gene expression changes in roughly 20% of unique genes that significantly changed with training
  • Examples of structural genes include COL4A1, COL4A2 and LAMA4. These genes have also been identified as important for differences in responsiveness to endurance training
  • methylation status could be part of the mechanism behind variable training response
  • Among the metabolic genes, MDH1 catalyzes the reversible oxidation of malate to oxaloacetate, utilizing the NAD/NADH cofactor system in the citric acid cycle and NDUFA8 plays an important role in transferring electrons from NADH to the respiratory chain
  • PPP1R12A,
  • In the present study, methylation predominantly changed in enhancer regions with enrichment for binding motifs for different transcription factors suggesting that enhancer methylation may be highly relevant also in exercise biology
  • Of special interest in the biology of endurance training may be that MRFs, through binding to the PGC-1α core promoter, can regulate this well-studied co-factor for mitochondrial biogenesis
  • That endurance training led to an increased methylation in enhancer regions containing motifs for the MRFs and MEFs is somewhat counterintuitive since it should lead to the repression of the action of the above discussed transcription factors
  • decrease with training in this study, including CDCH15, MYH3, TNNT2, RYR1 and SH3GLB1
  • expression of MEF2A itself decreased with training
  • this study demonstrates that the transcriptional alterations in skeletal muscle in response to a long-term endurance exercise intervention are coupled to DNA methylation changes
  • We suggest that the training-induced coordinated epigenetic reprogramming mainly targets enhancer regions, thus contributing to differences in individual response to lifestyle interventions
  • a physiological health-enhancing stimulus can induce highly consistent modifications in DNA methylation that are associated to gene expression changes concordant with observed phenotypic adaptations

5 Things You Need To Understand If You are Having Chronic Pain! - 0 views

  •  
    Chronic pain is a type of pain that usually lasts for weeks to months. This pain can come and go, and it can be anywhere in the body. Chronic pain can lead to anxiety, depression, and insomnia. Chronic pain is quite different from acute pain and there are some differences between the two types. People usually experience severe pain, when it is injured by a broken bone or a cut on the skin. This pain does not last long. Pain is not something that can be ignored. If it grows, it should be fixed. As fear and pain persist, one begins to think negatively. Long-term negative thoughts begin to form in his mind, a process called fear conditioning. This factor causes an increase in blood pressure and anxiety disorders. Chronic pain is difficult to treat, and results in increased pain, fear, and negative thoughts. Extreme levels of fear lead to more pain, and the cycle of pain threats can be difficult to break. One of the best pills used to treat body pain symptoms is Hydrocodone 325mg, which you can easily buy from any trusted online pharmacy, such as Pharma Health Online.

    No surprise, testosterone in men and women have different effects.  I just wrote a post on this.  Testosterone is positively associated with increased risk of diabetes in women, but inversely with men.  That is increased T in women equals increased Diabetes in women; contrast with increased T associated with decreased Diabetes in men.   But the interesting point is SHBG.  This study found a strong inverse association between SHBG with diabetes in women when compared to men.  Meaning: low SHBG is associated with an increased risk of type II Diabetes.  This is at the same time that testosterone is associated with an increased risk.

Wheelchair 4 Wheel Drive - 0 views

  •  
    A wheelchair is a wheeled mobility device in which the user sits. The device is propelled either manually (by turning the wheels by the hand) or via various automated systems. Wheelchairs are used by people for whom walking is difficult or impossible due to illness (physiological or physical), injury, or disability. The chair seat size (width and depth), seat-to-floor height, footrests/leg rests, front caster outriggers, adjustable backrests, controls, and many other features can be customized on, or added to, many basic models, while some users, often those with specialised needs, may have wheelchairs custom-built. The usual size of the rear wheel ranges from twenty to twenty-six inches in diameter. A larger wheel increases the height of the seat off the ground and decreases the rolling resistance, thus easing the effort of pushing. The rear wheels can be solid or pneumatic. Solid wheels have a low rolling resistance and are very easy to maintain. They are ideal for use in institutional settings or for indoor use in noncarpeted areas. Pneumatic wheels have better grip on carpeted surfaces and are better if there is going to be significant outdoor use, but they run the risk of flats and require higher maintenance. The flat tire problem can be circumvented by the use of a foam insert that can prevent leaks. Wire spokes are lighter in weight but higher in maintenance. Most older persons will select large plastic spokes referred to as mag wheels. The wheels can be offset posteriorly to decrease the risk of tipping backwards.

    Wheelchairs is designed for those who prefer a removable armrest wheelchair. A removable armrest allows for easy patient transfer in and out of the chair.This chair is available in a different seat width and comes complete with swingaway footrests. It also incorporates solid rubber casters for a smooth and easy roll. Both detachable and flip-back arms are designed for easier lateral transfers. Most Wheelchairs in this category have Desk-Length arms, a shorter arm that allows rolling up to a desk or table. All are folding-frame chairs and are available in different seat widths. Detachable armrest for use in conjunction with wheelchairs. The armrest is comprised of a horizontal member supported at one end by a vertical member. The horizontal and vertical members are releasably attached to the wheelchair frame, and the attachment of the horizontal member to the wheelchair frame allows rotation of the horizontal member from the normal position to a position of non-use behind the back of the wheelchair. Wheelchairs - Arm Rests: The armrests support the arms and shoulders in comfortable positions and are often used to push off of for transferring from sitting to standing or held on to for balance. Desk-length armrests are shorter than standard length rests and are often chosen so that a person can pull up to a desk or table for easier access. The shorter length of these armrests is undesirable if the wheelchair user needs to use them to assist pushing into a standing position. In this case a full-length armrest would be preferred. Wheelchairs - Footrests: The footrest and legrest support protect the lower leg and feet. If they are too high they decrease the weight carried through the back of the thighs and can cause increased pressure over the buttock region. If they are two low they can cause pressure over the posterior thighs and cause problems with clearing barriers in the environment such as incline transitions.

    When it comes to wheelchairs, young children have a different set of needs than adults. Aesthetically, devices designed for kids are often sleek and colorful, and functionally, they are typically lightweight and adjustable. As any parent knows, young people don't stay the same size for long and since a wheelchair is a major purchase don't want a simple growth spurt to render it useless. That's why kids wheelchair category offers models that feature seat width and depth adjustability, elevating legrests, and other versatile features. Pediatric walkers differ from adult walkers in several ways. For one, walking aids for children are usually adjustable, taking growth patterns into account; but many models also provide gait training and postural correction. Those caring for kids in their formative years must be concerned about more than just the young person's mobility, they must also consider their development.

  • The benefits for men older than 65 years of age were compared with those of younger men, and the improvements in body weight, metabolic factors, psychological functioning, and sexual functioning were of the same magnitude in both age groups
  • weight loss was progressive over the 6-year period, effects of testosterone on lipids and on psychological and sexual functioning reached a plateau after approximately 3 years and these effects were sustained

  • the severity of the metabolic syndrome is associated with the severity of lower urinary tract symptoms
  • The symptoms of the metabolic syndrome improve upon testosterone treatment and testosterone may thus have a favorable effect on lower urinary tract symptoms
  • it seems reasonable to conclude that the risks of testosterone administration to elderly men are not disproportionately higher in elderly men than in younger men.
  • Despite evidence to the contrary, physicians still harbor a wrongful association between testosterone and the development of prostate pathology (prostate cancer and benign prostate hyperplasia)
  • Not surprisingly, the incidence of prostate cancer was higher in older men; however, it was lower than expected in both groups
  • These observations suggest that the incidence of prostate cancer in patients receiving testosterone therapy, both in the younger and in the older group, was not greater than in the general population not receiving testosterone treatment
  • The historical fear that raising testosterone levels will result in more prostate cancer has been dispelled, particularly by the work of Abraham Morgentaler
  • Higher serum testosterone levels fail to show an increased risk of prostate cancer, and supraphysiological testosterone does not increase prostate volume or PSA in healthy men
  • This apparent paradox is explained by the "saturation model,"
  • Recent studies indicate no increased risk of prostate cancer among men with serum testosterone in the therapeutic range
  • In the present observational study, no cases of major adverse cardiovascular events occurred.
