Seeding cells into needled felt scaffolds for tissue engineering applications SUMMARY: Tissue engineering methods are under development that will enable the repair or replacement of a variety of tissues‚ including articular cartilage and bone. To engineer functional tissue it is necessary that scaffolds initially be seeded with a large number of cells distributed evenly throughout the scaffold structure. It previously has been shown that‚ compared to static seeding conditions‚ seeding scaffolds

The CELL THEORY‚ or cell doctrine‚ states that all organisms are composed of similar units of organization‚ called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin’s theory of evolution (1859)‚ Mendel’s laws of inheritance (1865)‚ and the establishment of comparative biochemistry (1940). Ultrastructural research and modern molecular biology have

In September of 1947 the Central Intelligence Agency (CIA) was realised and hatched‚ the eventuality of the intelligence reformation in the United States occurring after the Second World War. Less than a year before this date a Joint Congressional Investigation had come to the inevitable conclusion that the Pearl Harbour attack illustrated America’s need for a unified command structure and a more efficient centralised intelligence system. In an attempt to bring these conclusions into realisation

The Eyes of the Skin of Architecture Juhani Pallasmaa This book was written by Juhani Pallasmaa with regard to ‘Polemics’‚ on issues that were part of the architecture discourse of the time‚ i.e. 1995. It is also an extending of ideas expressed in an essay entitled “Architecture of the seven senses” published in 1994. As suggested by the title‚ this piece of literature attempts to highlight the importance of sensory experience in architecture. It is indeed a response to what the author terms

Stem cells Nowadays‚ stem cells are the hottest topic in the medical field. More and more researches are performed to investigate these mystic cells. In order to go deeper into this topic and fully understand it‚ let’s first take a look at the stem cells themselves‚ their origins and characteristics which make them so unique and crucial for the medical field. Stem cells are very complex and complicated‚ and‚ that is why‚ it takes a lot amount of time to get to the bottom of their structure to be

diagnosed with cancer. Skin Cancer is one of the most common types of cancers. Breast‚ prostate‚ lung‚ and colon cancer combined are still less than all the cases of skin cancer that are diagnosed in a year. Nearly half of all Americans who live to age sixty-five are expected to acquire skin cancer at least one time in their life‚ according to Medicinenet.com. The three types of skin cancer are Basal Cell Carcinoma‚ Squamous Cell Carcinoma‚ and Malignant Melanoma. Basal Cell Carcinoma (BCC)

The Cell Cycle Mitosis: the process by which cells reproduce themselves‚ resulting in daughter cells that contain the same amount of genetic material as the parent cell. Interphase Prophase Metaphase Anaphase Telophase Cytokinesis Cell Division Occurs in a series of stages of phases Interphase occurs before mitosis begins Chromosomes are copied (# doubles) Chromosomes appear as threadlike coils (chromatin) at the start‚ but each chromosome and its copy(sister chromosome) change to sister

STEM CELL RESEARCH AND THERAPYAND ITS IMPACTS ON SOCIETY Abstract There are several types of stem cells being used in stem cell research and therapy today. They are embryonic‚ adult and induced pluripotent stem cells. Each will be discussed further. This topic has stirred much moral‚ ethical and political debate as whether cells from fetuses should be used in this research. This impacts governmental policies on laws and funding. Another issue that must be analyzed is the
