who suffered from cervical cancer. Her cells have helped change the world of medicine. 6) What is the feeling of her family about the use of HeLa cells? The Lacks family was not informed that Henrietta’s cells were being used in research. They learned this 25 years later and they

characteristics of soft tissue are the basis for several clinical and nonclinical research studies, such as brain surgical simulation or breast needle biopsy (Kaster et al., 2011; O’Hagan & Samani, 2009). Usually, anomalies found within the breast are investigated by palpation techniques, in which responses of soft tissue to large deformation are utilized (Goodson, 1996). Recent research on the mechanical properties of soft tissue under compressive load has revealed that tissues exhibit a linear stress-strain

Finally the characteristics of the tissue at and surrounding the impact site has been shown to influence the resulting response [19]. These characteristics are referred to as collectively as contact phenomena. Contact phenomenon includes local variables such as skull shape, size, geometry, density and mass of neural tissue, thickness of scalp and skull, hair style, ratio of brain-head weight and strength of the head-neck junction[19]. These local variables seem to greatly different between the two

injury involving tendons or ligaments, which can be career or life ending depending on the severity. The injured soft tissue usually has a poor blood supply so they are prone to healing with scar tissue. This makes the healed area less elastic and decreases the function of the tendon or ligament, and re-injury to the soft tissue increases. Another issue associated with soft tissue injuries is the inflammation of a tendon called tendonitis that can be seen in 43% of horses returning to work (Alves

al, 2006). The success of the use of ultrasound has been recorded as early as the 1930’s, when in Berlin, sciatica in patients had been shown to have improved greatly. This evidently resulted in further research and new treatment methods being created (Stanley, 1958). Since then a lot of research has been carried out and advances in the use of ultrasound has been made and are continuing to be made all the time. The effects of ultrasound in rehabilitation will be researched and examined to understand

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

bioactivity by stimulating bone growth2. Some are designed to incorporate drugs that can be release by external stimuli or by time releasing mechanisms. These bioceramic drug delivery systems are being researched, as well as nano scale ceramics. Current research is not only looking at new and improved bioceramics but is also looking into using ceramics for use in cancer treatments. The use of ceramics in hyperthermia therapy is one of the methods currently being looking into3. The ceramic that is used

Hydroxyapatite, substitute apatite, biphasic system. They often have similar properties to the composition of bone. Their objective is to only mimic the mineral component of bone. They can also be considered bio-absorbable. They avoid the formation of fibrous tissue, and encapsulation of the implant, thus isolating it from the body system (this is a result of an immunological response). A lot of metal orthopedic implants are coated with this material, to help avoid this type of reaction. Nonoxide ceramics An

Introduction and Function Elastin is the one of the key components in the elastic property of tissues found in human tissues such as arteries, lungs, and elastic cartilage to name a few (Jacob, Sauvage, Osbourne 1). Elastin is mainly composed of amino acids glycine and proline, which are hydrophobic and are combined with lysine residues in crosslinks (NCBI 1). It plays a fundamental role in the recoil of tissues after being stretched, which is critical in maintaining the cells health (Weiss 1). Thirty

Over one hundred million animals every year die from animal testing, in the medical and cosmetic fields alone (“Experiments on Animals: Overview”). Animal testing is as big of a problem today as it has been in the past. Most people do not agree with animal testing today but years ago it was one of the only ways of testing. It was considered, if not the only, effective and efficient ways of testing a product’s toxicity. To date, animal testing is not warranted because of the development of new technology
