How to Look younger in old age - Exercise Prevents Muscle Aging and atrophy

You must be familiar with the many leading celebrities of the world and you must be wondering why they are not getting old, how they look so younger in old age. Especially Male celebrities of today's era. There physique and muscles look and feel younger as compared to their age.
Scientist discovered the secret behind it.
University of Illinois researchers found out that an adult stem cell is present in muscle and this stem cell is responsive to exercise, a discovery that may provide a link between exercise and muscle health. This stem cell has the ability to regenerate the injured and aged muscle cell. These findings could lead to new therapeutic techniques using these cells to rehabilitate the injured muscle and prevent or even restore muscle loss that normally occurs with age.
Now the question is "how exercise prevent muscle ageing.
Mesenchymal Stem cells have been known to be present in the skeletal muscles and are responsible for minor repairs on the injuries which result from injections and chemical.
Now, Exercise also causes a kind of minor injury to the muscles as a result of the mechanical strain of heavy exercise on the muscles. Scientists believe that these mesenchymal stem cells accumulate in the affected muscle area and take part in regeneration and adaptation of muscle. Adaptation is a process in which in response to mechanical strain (as occur in body-building exercise) muscle increase in size to minimize the effects of strain next time.
These mesenchymal cells do not produce muscle cells by themselves. Instead, these stem cells release a large number of growth factors which in turn stimulate muscles cell regeneration.  Now scientist wonder that a large number of growth factors which are being released by stem cells improve only muscle health or they also take part in the improvement of the health of the whole body. Because obviously these growth factors would also be absorbed by the blood and there are high chances of their effect on other body parts such as bones etc.
Scientist are now trying to answer these questions and research is going on.
But whatever the results of that research would be. Scientist are sure that exercise and proper diet is the key to younger and healthier looks.

Human Parasites, Types of Parasites, and Classification

Parasite: A parasite is a living organism which gets nutrition and protection from another organism where it lives. Parasites enter into the human body through mouth, skin and genitalia. In this article, we will generally discuss the types and classification of parasites. It is important from an academic point of view. Those parasites are harmful, which derives their nutrition and other benefits from the host and host get nothing in return but suffers from some injury. Types of Parasites Ecto-parasite: An ectoparasite lives outside on the surface of the body of the host. Endo-parasite: An endo-parasite lives inside the body of the host, it lives in the blood, tissues, body cavities, digestive tract or other organs. Temporary parasite: A temporary parasite visits its host for a short period of time. Permanent parasite: Permanent parasite lives its whole life in the host. Facultative parasite: A facultative parasite can live both independently and dependently. It lives in the

How to taper off, wean off beta blocker, atenolol, Propranolol, Metoprolol

Beta blockers include, atenolol (Tenormin), propranolol (Inderal ) and metoprolol (Lopressor) and are used to treat high blood pressure, certain cardiac problems, migraine and few other conditions. People usually take atenolol, propranolol or metoprolol for many years as a treatment of high blood pressure or after having an episode of heart attack . Sometimes, it becomes necessary to withdraw these beta blockers due to their potential side effects that trouble the patients or sometimes doctor wants to change the drug and shift the patient to some other anti-hypertensive medicine. No matter whatever the cause is, whenever, a patient who has been using a beta blocker for a long period of time, and he needs to be stopped from further usage of that beta blocker, must not stop taking it. One should taper off the dose of a beta blocker. Now a question arises how to wean off or taper off a beta blocker? The method of tapering off beta blocker varies from individual to individual. Allow you

Difficulty in standing up from a sitting or squatting position, Causes & Solution

People who feel it difficult to stand up from a sitting or squatting position may have problem in one or more of the following structures. 1. Knee joint 2. Muscles of legs, thighs or buttock 3. Muscles of arms 4. Cerebellum Let’s now explain one by one, what kind of problems in above structures may cause difficulty in standing up from a sitting or squatting position. 1. How do problems in knee joints lead to difficulty in standing up? Knee joint is one of the primary and most affected joint that takes part in standing up. Other joints that take part are hip, ankle, knee, elbow, wrist and shoulder joint. Knee joint gets the most strain , and also knee joint is comparatively less supported. That’s why usually it’s the knee joint that starts to cry first because of arthritis. Knee joint arthritis causes long term knee pain , that makes the movement difficult at knee joint. Arthritis also makes the knee joint stiffer and slower and its range of motion also decreases. All these affects coll
