UNLV Theses, Dissertations, Professional Papers, and Capstones
Introduction
Mesenchymal stem cell (MSC) research is a contemporary topic in modern healthcare. These cells have the ability to divide and generate progeny, which then become committed to specific and distinctive end-stage phenotypes, such as cartilage or bone (Caplan 1991). MSCs have been isolated from a variety of tissues such as the umbilical cord, bone marrow, adipose tissue (Ding, Shyu & Lin 2011) and dental pulp (Takeda et al 2008). Although dental pulp is a viable source for MSCs, peer reviewed research has given limited attention to its retrieval process through intentional tooth splitting of extracted teeth. The purpose of …

Mesenchymal stem cells are derived from a variety of human tissues and are being bioengineered and studied for possible uses in the advancement of medicine. Recent efforts are being focused on Dental Pulp Stem Cells (DPSC's) due to the accessibility of this tissue. Many factors influence DPSC quality and quantity, including the specific methods used to isolate, collect, concentrate, and store these isolates once they are removed. Ancillary factors, such as the choice of media, the selection of early versus late passage cells, and cryopreservation techniques may also influence the differentiation potential and proliferative capacity of DPSC isolates.

Designing A Mechanical Linkage Capable Of Decreasing Force Transfer From The Facemask To The Protective Helmet When Loading Occurs, Levi Hansen
UNLV Theses, Dissertations, Professional Papers, and Capstones
Introduction
Sports that involve extensive personal contact have a high incidence of injury. The introduction of regulations mandating the use of personal protective equipment in these sports is the most common injury control strategy (Marshall et al., 2002). Negligible attention has been paid to the mechanical linkage between the facemask and helmet as a means of reducing force transfer from the facemask, through the helmet, and to the head and or neck of the athlete.
Methods
A novel prototype mechanical linkage of reasonable simplicity that provides 360° of freedom in motion capable of decreasing force transfer from the facemask to …
Determinants Of Head And Neck Cancer Survival In Nevada For 1995-2008, Xiao Q. Li
Determinants Of Head And Neck Cancer Survival In Nevada For 1995-2008, Xiao Q. Li
UNLV Theses, Dissertations, Professional Papers, and Capstones
Head and neck cancer (HNC), also known as oral cavity and pharyngeal cancer, comprises a group of cancers that arise in the head or neck region, such as the nasal cavity, sinuses, lips, mouth, salivary glands, and pharynx. Use of tobacco, alcohol, or a combination of the two, are major risk factors for head and neck cancer. Approximately 75% of oral cancers are attributable to smoking and/or alcohol consumption. More recently, the human papilloma virus (HPV) has also been associated with the development of head and neck cancer.
The objective of the present study is to investigate head and neck …
