Background and aim : Skeletal muscle is reduced in various chronic disease states resulting in sarcopenia. Sarcopenia is an objective and measurable clinical marker for malnutrition. Slice-O- Matic has been used to measure skeletal muscle from computed tomography (CT) images. However, it is expensive and not easily available. In this study, we measure skeletal muscle mass from CT images using Adobe Photoshop and compare it to Slice-O-Matic in order to realiably validate a novel and more cost-effective
structural skeleton (cytoskeleton) within the muscle cells, through the outer membrane (sarcolemma) of each cell, to the tissue framework (extracellular matrix) that surrounds each cell (Straube and Campbell, 1997). Due to defects in this assembly, contraction of the muscle leads to disruption of the outer membrane of the muscle cells and eventual weakening and wasting of the muscle Symptoms: Up to the age of 1-3 years, affected boys have normal muscles that is they learn to stand and walk later than

Some go their whole lives without knowing what it is like to even crawl. SMA is the number one genetic killer in infants under two (What is Spinal Muscular Atrophy?) it affects people for the rest of their life and the disease is devastating, so why is it taking a backseat to other infant diseases such as SIDS? SMA is a genetic
What is Spinal Muscular Atrophy? Spinal Muscular Atrophy is a disease that can destroy the “lower motor neurons in the nerve cells” (Spinal Muscular Atrophy, 2015). Spinal Muscular Atrophy affects the spinal cord that controls our everyday movement. These cells send out processes in the peripheral nerve to eventually make contact to our muscle, legs, arms, chest, breathing muscles. SMA is a very rare disease but it is the second most common recessive disease after cystic fibrosis. It is a very serious
the effects of microgravity on the human body and how to counteract these effects. One major concern of prolonged exposure to microgravity is muscular atrophy. Muscular atrophy is the condition of losing the proteins that make up muscle cells, leading to degradation of muscles (“Muscle Atrophy” 1). This loss of muscle cells happen when muscles are not used,
loss of gravity which can either be in space or stimulated space. The musculoskeletal system is particularly affected during this condition. Muscle atrophy results primarily from decreased protein synthesis (Hu et al., 2014). Thus while in space there could be a reduction of protein synthesis for up to 50% within several hours which can lead to loss of muscle protein (Fitts et al., 2001). Microgravity also results on bone mineral loss of about 4% of weight bearing bones. This affect can be due to
occur de novo rather than inheriting a defective copy of the gene from each parent. This deficiency results in degeneration of motor neurons causing muscle atrophy, particularly in the limbs and the muscles that control the mouth, throat and respiration. There are four types of SMA, types I, II, III, and IV which are defined based on the severity of muscle weakness and the age of symptom onset. SMA type I (Werdnig-Hoffmann disease) is the most severe. SMA type I-affected infants represent approximately
peripheral nervous system to send signals or relay sensory information. CMT typically presents with distal predominance of limb-muscle wasting, weakness, and sensory loss , . Symptoms start in the feet, which commonly have high arches, hammer toes, intrinsic muscle weakness, and wasting. The disease then begins to affect the legs and the lower thighs, which results in distal atrophy of the lower limbs. The hands become affected, followed by the forearms. Sensory loss also
Steroids Anabolic steroids, technically known as anabolic-androgenic steroids, are drugs that are related to the cyclic steroid ring system and have similar effects to testosterone in the body. They increase protein within cells, especially in skeletal muscles. They address the development and maintenance of masculine characteristics such as the growth of the vocal cords, testicles and body hair. Anabolic steroids were first made in the 1930s, and are now used therapeutically in medicine to stimulate bone
comparable. The reasons for the effects of spaceflight are even more complex than that of detraining. During flight astronauts go through changes in the muscular strength and mass, similar to that of injured athletes, yet at an even fast rate. The muscles that keep the body upright on earth decline in strength and mass inevitably to allow the body to respond appropriately to microgravity. The rate at which strength and mass are loss again depends on the physical condition of the astronauts and the
deleterious. What are Anabolic Steroids and how do they work? Anabolic steroids are synthetic derivatives of the male hormone testosterone. Most healthy males produce 2-10 milligrams per day of testosterone. Testosterone is responsible for muscle development, facial hair growth, and deepening of the voice. The hormone produces these results when it is absorbed from the bloodstream by certain types of cells. Molecules of testosterone fit into receptor sites located inside the cells, just as
HEAT THERAPY BE AN EFFECTIVE TREATMENT FOR SARCOPENIA? Introduction These days muscle pain and spasms have become the most common complaint of many working men and women. To avoid this pain most of them rely upon spa’s to lessen their pain. One of the main techniques used in the spa’s to reduce muscle pain is heat therapy. This nonpharmacological technique helps in reducing the muscle pain as it vasodilates the muscle causing the blood flow to increase at the site of inflammation or injury (Mohammadpour

This indicates that I am at an increased risk of musculoskeletal injuries because of repetitive body movements and muscle atrophy.

She had been so neglected she had sat with her head down, depressed so long that her muscles in her head and neck had started to atrophy. She could barely chew it was so bad. She was so dehydrated that her nose was dry, cracked and even raw in spots from where he had tried to lick moisture back onto it. She was so afraid of everything that she cowered and hid
Introduction to Duchenne Muscular Dystrophy Duchenne Muscular Dystrophy is caused by the mutation of the necessary muscle protein dystrophin that occurs on the X chromosome, and due to the way the disease is inherited it usually affects males. Males have only one copy of the X chromosome from their mother and one copy of the Y chromosome from their father. If their X chromosome has a DMD gene mutation, they will have Duchenne muscular dystrophy. According to the US National Library of Medicine (www
Introduction This module of study has focused on many aspects of human health, anatomy, and the disease process. It has included such topics as the human organ systems, the mechanism of disease and the resulting disruption of homeostasis, the integumentary system, and the musculoskeletal system. The following case studies explore how burn classification will affect treatment, how joint injuries can disrupt mobility, and last, how a sedentary lifestyle can contribute to a decline in a person’s health

The rotator cuff is a group of muscles and tendons in the shoulder that connects the upper arm (humerus) to the shoulder blade (scapula). The rotator cuff tendons provide stability to the shoulder while the muscles allow the shoulder to rotate. The muscles in rotator cuff are Teres minor, Infraspinatus, Supraspinatus, and Subscapularis. The muscles in the rotator cuff inserts at the scapula and has a tendon that attaches to the humerus. The rotator cuff is often a subject to athletic injuries. These
longevity is well established. Regular exercise leads to a reduction in the risk of coronary heart disease, in which fatty deposits (plaque) form in blood vessels supplying the muscular wall of the heart, compromising oxygen delivery to the heart muscle. In addition, with regular exercise the efficiency of the heart during exercise is increased. Many people exercise to lose weight. A calorie is a unit that measures the energy content of foods and the energy expenditure by the body. When the
