The present study determines the effect of compression over bioimpedance of healthy soft tissue (in-vitro and in-vivo). Electrical impedance spectroscopy (EIS) is a promising tissue characterization and tumor detection technique that uses tissue impedance or admittance to characterize tissue and identify tissue properties as well as cell structure. Variation in EIS measurements while applying pressure suggests that compression tends to affect soft tissue bioimpedance. Moreover, the displacements in tissue caused by applied compression may provide useful information about the structure and state of the tissue. Thus combining the changes to the electrical properties of tissue resulted by applied compression, with the changes in tissue displacements caused by applied compression, and consequently measuring the effect that electrical and mechanical properties have on each other, can be useful to identify tissue structure. In this study, multifrequency bioimpedance measurements were performed on in-vitro and in- vivo soft tissue at different pressure levels. Increasing compression on the in-vitro tissue results in an increase in both extracellular resistance and membrane capacitance while it causes a reduction in the intracellular resistance. However, as the compression over the in-vivo samples increases, the intracellular and extracellular resistance increase and the membrane capacitance decreases. The in-vivo measurements on human body are also tested on contra- lateral tissue
When the tissue was immersed in calcium free solution and stimulated with Ach via the PMC pathway, a small contraction (1.15g) was observed compared to the baseline contraction trace (6.37g). Contraction recovered when the bathing solution was changed back to normal Krebs (5.63g). For the next stimulus, K+-depolarising solution, the baseline control produced a force of 6.17g in normal Krebs solution. When calcium free K+-depolarising solution was used to stimulate the tissue in calcium free solution, via the EMC pathway, the tissue barely contracted at 0.09g. In the second experiment, verapamil was added to the bathing solution. When the tissue was stimulated by Ach in the presence of verapamil, it
Have you ever sat down on Thursday, Monday, or Sunday to watch some espn NFL Football? Well I certainly have, Have you ever just looked at the players and realized they're getting paid millions to represent our country? Then they just start kneeling at games, That makes me disappointed in them for millions they still don’t respect the flag. Whenever I see a player kneel I always think, why are you kneeling, who even started this, and when was this started.
I am interested in pursing the controversy sparked by the kneeling of NFL players during the national anthem. I chose this topic because I am an NFL fan and interested in the responses generated towards this action. The things I will research are the rules of kneeling in NFL games to see if the players are technically allowed to kneel during the national anthem. I would research the purpose of the kneeling of NFL players, what protest it symbolizes, and how it started. To fully understand this topic, it is essential to research about the origin of this conversation. Another thing I would research are people's thoughts towards this stance like the government and the NFL organization. Researching about the government and the organization's perspectives
The Effects of Different Stretching Techniques on Myosin and Actin Fibers and How it Affects Athletic Performance
a. Inform a lifeguard, if one is close. If not, request that somebody call 911.
Leave the socks to soak for a short duration of time then wash the stockings. Once washed, ensure you rinse them to remove any excess liquid. Once you have completed this process, wrap the socks in a towel to make a package, and apply pressure to the package to remove as much moisture as possible (this can be done by placing the package on the ground and standing on it to tread it flat). Once you have removed as much moisture as you can, remove the stockings from the packaged towel and hand them up to
Occupational health service providers are trained to treat sport injuries.Getting injured can be a nightmare for an athlete. An injury requires that an athlete sit out of the games until he or she recovers. That is why an injury can not only take a physical toll on a person, but it can also take an emotional toll.
Pulling or straining a muscle is easier than most people think. It can happen to the fittest athletes and even the most limber young children, not just older adults. This type of injury can take some time to heal, which reduces the ability to exercise in the mean time. Luckily, muscle pain can be prevented by using the following five easy tips:
Around ten years ago my life was changed forever when I became a victim of a car accedint. Once at the hospital it was found that I was had two compression fractures and that the T12 fracture could cause paralysis or other issues. The deciding factor seemed to depend on the swelling muscles around the breaks. Unluckily the swelling had already begun. Compression fractures of the spine are fairly common in car accidents but I wasn't sure just what it meant.
Arterial tourniquet is used in limb surgeries to provide a bloodless field and improve the surgical conditions. However, tourniquet inflation is associated with some consequences that may be relatively benign in healthy individuals, but could be hazardous in patients with impaired cardiac conditions [1]. Tourniquet inflation is associated with an increased sympathetic outflow, an increase in arterial blood pressure and severe pain [2-4].
Contractility is an ability to shorten a muscle with force and acuteness when stimulated. Contractions are responsible for all body movement this helps to keep the body alive. When the muscle contracts they design different strengths of movement. There are four different types of contractions. The isotonic contraction is when force is generated by the changing the length of muscle. A concentric contraction is when a movement causes the muscle to shorten by generating force. An eccentric contraction is when the muscle causes itself to elongate in return to a greater opposing force. An isometric contraction is when the muscle generates force without changing the length of your muscle. All of these allow a human to move their eyes, participate
Contributions with the field of biomechanics along with advancements in technology have led to improvements in the general and public safety pertaining to motor vehicles. Air bags have reduced mortality rates in motor vehicle accidents significantly throughout the years. Air bags have undergone development for many years, first being introduced in the 1960’s with the release of the first commercial air bag in the 1980’s appearing in motor vehicles. Air bags have been a subject of research and tests throughout the years currently still evolving. Through studies and research collected, air bags have shown to be a beneficial innovation to the health and safety of the public.
The word "Cancer" means a group of diseases that are characterized by unrestrained cellular development. It It refers to cellular intrusion into neighboring tis-sues and may turn into metastasise if not treated at early stage. The most widely diagnosed malignancy in males is prostate cancer. Peripheral zone of the gland is the place where prostate cancers are generally found. It constitutes a dense arrangement of cancerous epithelial cells commonly in small form, penetrating glands with a symmetrical de-crease in stromal volume [2]. B. Lee et al. [3] used tissue bio-impedance to differentiate between the diseases because morphological differences between normal and malignant prostate tissue are present and sensitivity of electrical im-pedance spectra to cellular structure was known. Bio-impedance is one of the properties referred to a tissue’s re-sistance when electrical current flows in the tissue. It also means the ability of tissue to store electrical charges. Bio-impedance normally depends on spacing of cells, cellular density and size, and the components of the extracellular ma-trix (ECM). Differences between the malignant and benign tissue impedance of can be a distinguishing criteria for pathological procedures for cancer detection [1]. Actually, it was shown by Skourou et al. [4] that when there is tumor, the tissue impedance may be more sensible than conventional imaging techniques, such as computed tomography (CT) and ultrasound imaging. Normal and neo-plastic
Pressure injury, due to its high prevalence & probability, is nowadays seen as a patient safety issue internationally. As patient 's safety is paramount, a great importance is accorded to the issue. Even the performance of hospitals is benchmarked against the skin care quality, an attribute of quality care. This comparative essay outlines the evidence-based best practice recommendations to abate the risk of pressure injuries to patients in care. These recommendations, in essence, relate to the five research journal articles published recently.
