A common skin fungus, Malassezia globosa may invade deep tissues through the skin or by other means, then cause tumor growth, according to a new study. The study results were reported in mBio, an open access journal of the American Society for Microbiology.

"It is important to take care of skin not only for beauty, but also for health. As a factor promoting tumor growth, intertumoral microorganisms need to be paid more attention."

 

Qi-Ming Wang, Ph.D., corresponding study author, professor in the School of Life Sciences, Institute of Life Sciences and Green Development, Hebei University, Hebei, China

Recently, an increasing number of studies have shown a relationship between fungus and cancer. In the new study, Wang and colleagues subjected mouse breast cancer cells to tumor transplantation and then injected the M. globosa into the mammary gland fat pad. At the end of the experiment, they collected the tumor tissue to measure the tumor size and observe the content of intertumoral M. globosa. The researchers discovered that M. globosa colonizes in breast fat pads leading to tumor growth. As a lipophilic yeast, the breast fat pad may provide an external source of lipids for the development of M. globosa, say the researchers. They also found that the pro-inflammatory cytokine interleukin (IL)-17a/macrophage axis plays a key role in mechanisms involved in M. globosa-induced breast cancer acceleration from the tumor immune microenvironment perspective.

"Although still controversial, the relationship between microbes and cancer is gaining attention. The imbalance of the microflora in the tumor may lead to disorder in the tumor microenvironment," Wang said. "For example, Helicobacter pylori emerged as a potential cause of gastric cancer. In addition, Fusobacterium nucleatum has been identified as a potential colorectal cancer biomarker in stool and is predominantly found in the tumor microenvironment. Bacteria or fungi may play a direct (e.g., toxins) or indirect (e.g., inhibition of anti-tumoral immune responses) role in the tumorigenesis pathways of many of these risk factors. The imbalance of microbial homeostasis in tumors has a certain significance for cancer diagnosis, treatment and prognosis." 

According to Wang, although the researchers found that M. globosa can promote the growth of tumors, the related transmission route is still unclear.

The Science Behind Foam Rolling: Relieving Muscle Tension and Improving Flexibility

 

As people try to embrace the newfound knowledge of producing a healthy active lifestyle, one piece of equipment that has caught much attention in recent times is the foam roller. Still, more than a simple piece of exercise equipment, the foam roller has turned into an athlete’s essential aide, a fitness freak’s must have tool to help them tone muscles, and even an everyday person’s preferred tool to help them ease out the kinks after a long day at work. 

By Samntha Naidu

However, how does foam rolling work, and how can it be incorporated appropriately into other activities for good health? In this article, you will discover more about the biomechanisms that would make foam rolling one of the most effective methods for muscle release, fitness flexibility, and musculoskeletal health.

Whether you are an athlete who trains every day, an office worker with a high level of sedentary lifestyle, or just a person who wants to be healthy and have good body flexibility, you should be knowledgeable on how foam rolling works so that it can be incorporated into your daily healthy regimen.

Understanding Muscle Tension

Before discussing the benefits of foam rolling it is important to understand why muscles get tense and the consequences that this has. Contraction of the muscle can be brought about by activities such as exercise, movement, stress, and even poor posture.

This is because when our muscles have been pulled or used frequently or have been stretched for quite some time, then their state becomes rigid and this causes numerous negative effects.

Muscle tension also tends to reduce flexibility which is one of the key reasons why people must not tense up their muscles frequently. The inability to move a muscle freely is the main cause of reduced flexibility, which in turn limits one’s ability to perform physical work or take part in physical exercises. They also may lead to more inflexibility, since the muscles and joints cannot move smoothly through each particular range of motion.

Another potential problem created by muscle tension is pain and discomfort. Muscle fatigue results from the accumulation of lactic acid and other metabolic waste products in the muscles causing muscles to have a ‘burning’ feeling, while muscle contraction exerts pressure on nerves leading to sharp, or they may radiating pain.

The Science of Foam Rolling

The actualities of foam rolling can, of course, be reduced to the process of myofascial release. Fascia is a fibrous structure of connective tissue, running throughout the body and enclosing muscles, bones, and other parts of the human organism. When this fascia becomes scarred or stuck it can cause muscle tension, pain, and even limited mobility.

Foam rolling, in effect, involves applying a certain amount of pressure to the muscles that need to be rolled, thus, breaking the adhesions within the fascia. This process known as the myofascial release has some benefits such as improvement of blood flow, minimizing of inflammation, and improvement of the flexibility and mobility of the muscular system.

Another advantage of foam rolling; particularly during physiological functioning is the boost in blood circulation. Foam Rolling works by exerting pressure on the affected muscles hence enhancing the flow of oxygenated blood to such parts to assist in the elimination of lactic acid and other metabolic wastes produced by muscles. The augmented blood flow can not only relieve the sensation of developing microtrauma within the muscles but also help the body recover them.

As well, foam rolling is also said to alleviate inflammation contained in the muscles in addition to enhancing blood circulation. Compression produced by the foam roller employed in this kind of treatment can help in the breakdown of substances that cause inflammation including cytokines and prostaglandins that cause muscle pain and stiffness. Effects such as less inflammation, therefore, make foam rolling helpful in helping one recover quickly and with ease to engage in physical activity again.

Foam Rolling Techniques and Best Practices

However, when it comes to foam rolling, some pearls of wisdom should be seen and understood to be able to harness the most out of it. In the case of foam rolling, it is essential to keep the right posture of the body and apply the right amount of force on the muscles that need to be worked on.

First, stand with your feet shoulder width apart resting the foam roller flat on the floor and aligning this so that the part of your body that you want to target is on it. For the initial press, just tilt back and forth with a fair amount of pressure. Do not press the guide wheel on bony protrusions or a part that feels tender when the is applied to them as this is painful and may cause harm.

The time spent on foam rolling and its applicability depends on numerous factors including goals and health condition of the person using it. While exercising one must spend from one to two minutes on each muscle group, several times a week. As a part of proper warm-up or stretching, foam rolling should be used before workout or after exercising.

The degree of foam rolling should be moderate for the person depending on his or her flexibility and overall tolerance rate. Beginners might also discover that using a softer foam roller or being less forceful during the application process is more bearable than that and on the other hand advanced rollers might obtain better results with additional pressure using a deeper roller or a massage ball.

Integrating Foam Rolling into a Healthy Lifestyle

Foam rolling is an effective method that can be relevant for the implementation by different personalities starting from active athletes and up to busy office clerks. Foam rolling as a part of a healthy lifestyle offers a lot of benefits among which the most important ones are:

Foam rolling can be more useful to active personalities like athletes and fitness freaks. Using foam rollers before a workout warm up helps build the muscles to be able to do the work while after a workout using the foam rollers helps reduce the muscle's soreness and inflammation. Furthermore, foam rolling exercise is useful for preventing injuries because of the enhanced flexibility and mobility that comes along with it.

At the same time, people who sit in the offices and almost do not move throughout the day can get a lot of benefits from foam rolling. Sitting for long hours results in the muscles tightening up and developing imbalances particularly so in regions such as the hips, lower back, and the shoulders.

Foam rolling should thus be made part of the activities done regularly to counter the impacts of extended sitting especially for those with desk jobs to enhance their flexibility and reduce muscle and bone harp.

Choosing the Right Foam Roller

Foam rolling has been known to be either very effective or very unbearable depending on the kind of roller one uses. Foam rollers can be categorized into various types of density, texture, and size, and all these have their special features.

These include firm rollers commonly of dense materials including EVA foam and High-Density polyethylene and are used for giving a more ‘massaging’ experience to the skin. These rollers are only useful for people who can endure the pain that comes with rolling hard on the body or in cases where one wants to target some deep muscles.

On the other hand, foam rollers with lesser density mainly those with softer and more flexible skin like gel foam rollers are best suited for tender muscles or those with tender muscles or people who are beginners in foam rolling.

rollers with cross-sectional dimensions, such as ridges, bumps, or grooves, can offer more bonuses for muscles and subgroups that for tangible reasons are more sensitive or stressed. One types of rollers are more characterized by a consistent level of rolling feeling and therefore is suitable to a large variety of users.

Conclusion

The science behind foam rolling is clear: this simple yet effective tool can play a crucial role in relieving muscle tension, improving flexibility, and supporting overall musculoskeletal health. By understanding the physiological mechanisms at work and incorporating proper foam rolling techniques into a healthy lifestyle, individuals can unlock a world of benefits.

Whether you're an active athlete, a desk-bound professional, or simply someone seeking to enhance your overall well-being, make foam rolling a regular part of your routine.
