HIF-1? And VEGF are also involved in osteogenesis, so the influence of these growth factors on the differentiation choices being made by the seeded stem cells is unknown (Polzer 7). The impact of prolonged hypoxic conditions on the seeded cells is another. Although Polzer and colleagues examined the timing of cell seeding relative to prevascularization, they discovered that the artificial scaffold rapidly filled with connective tissue. This process effectively clogged the matrix and prevented efficient seeding.
By comparison, researchers conducting spinal cord injury research into the efficacy of regenerative medicine techniques have been producing promising results (Sykova et al. 1113-1114). Hydrogels seeded with mesenchymal stem cells or bone marrow stem cells have produced positive results in both animal models and in phase I/II clinical trials. In rodents, the lesions were smaller 35 days post surgery and were functionally advanced compared to controls. White matter in the spinal cord was more intact and axons had begun to invade the scaffold from both ends of the transection. While most of seeded cells produced connective tissue, as the scaffold was being degraded by macrophages it was being replaced by additional connective and vascular tissue, astrocytic processes, and NF-160 positive axons. Functionally, patients who undertook the regenerative medicine intervention appeared to suffer no ill effects and may be doing better than they would have without the surgical intervention.
The research conducted by Polzer et al. And Sykova et al. explains why the use of an artificial scaffold remains a controversial regenerative medicine...
Appalachian Faith Healers Folk magic has been part of the Appalachian culture since the first Scottish and Irish people settled in the Appalachian Mountains in the 1700's. However, the development of folk medicine and faith healing in the Appalachian Mountains is a uniquely American experience. Appalachian folk medicine evolved from elements of European and Native American culture. In fact, today there are four different types of folk medicine practitioners in Appalachia:
Faith Integration in Nursing Leadership For the faith-based nurse, the spiritual dimension is central to nursing practice, just as clinical knowledge and technique are at the heart of the biomedical model. For the nurse leader, being active, caring and a being a supportive listener will go a long way to provide assistance in helping patient's cope with fears, anxieties, and medical history. Despite the models of patient-centered care, it is easy
Healthcare & Faith The author of this report has been asked to answer a few questions pertaining to faith and healthcare. The first question will be a compare and contrast of Christianity and Buddhism using the seven worldview questions as a prism. The second question asks the author to do a comparative analysis of the two faith systems and religions. Next, the author will explain the author's personal spiritual perspective on
Faith and medicine often work in parallel. They do not cross each other. While in grave medical situations, people may pray and have faith their loved ones will recover, often there is no intersection between both areas. When there is an intersection, that is when questions arise of whether a person should choose medicine over faith or vice versa. In the "Healing and Autonomy" case study, faith and medicine place
Healing Rituals Across Islam I was just 15 years old, and one day my grandmother found me. Left by a rebel at the side of the road my, grandmother knew. She knew by the fear in my eyes that I had just been raped. When she saw me she cried, and took me inside for no one to see me. She then went to the bush to find country medicine, and
Faith Diversity Diversity Faith Expressions Health Care Provider and Faith Diversity Health care professionals working at different levels meet several patients that belong to different regions of the world and have different faiths. Although, every health care professional has firm belief in his own faith but he should also have the ability to accept the diverse faiths concept. He must respect all religions and should not argue with the patients regarding their spiritual
