Introduction: The sella turcica has gained importance as a stable bony landmark in cephalometric studies.
Aim of the work: The aim of the work was to explore the changes that accompany postnatal ontogeny of the sella turcica until full development, and to verify its contribution in age estimation and sexual assignment among Egyptians.
Subjects and methods: Six selected measurements of the sella turcica of 215 Egyptian patients were assessed using Multidetector Computed Tomography (MDCT). The patients represented different ages and were referred to the Radiodiagnosis and Intervention Department. The gathered data were then subjected to statistical analysis including correlation and …

We identified the mitochondrial DNA haplogroups A, B, C and D in 75 present-day Maya individuals, 24 Maya individuals of the colonial period and one pre-Columbian Maya individual from Quintana Roo, Mexico. We examined these data together with those of 21 Maya populations accounting for 647 present-day Maya individuals and 104 ancient Maya individuals. A demographic study based on the analysis of fertility and endogamy was carried out in two modern Maya populations to identify cultural factors that influence the mitochondrial haplogroup genetic diversity. Most present-day and ancient Maya populations show a distribution pattern of mitochondrial haplogroup frequencies A, C, …

A number of recent articles have appeared on the hominin Denisova fossil remains. Many of them focus on attempts to produce DNA sequences from the extracted samples. Often these project mtDNA sequences from the fossil remains of a number of Neandertal fossils and the Denisovans in an attempt to understand the evolution of Mid Pleistocene human ancestors. These papers, introduce a number of problems in the interpretation of speciation in hominins. One concerns the degradation of the ancient DNA and its interpretation as authentic genetic information. Another concerns the idea of “species” versus that of “population” and the use of …

This study investigates the relationship between O and H isotopes in samples of Mexican hair and drinking water. The purpose of this study was twofold. First, we wanted to quantify the relationship between isotopes in Mexican hair and tap water to understand the impact of water stress and differing socioeconomic status on accurate predictions of drinking water. Second, we wanted to determine whether currently existing semi mechanistic models could accurately represent the relationship between hair and tap water. For this study, we used a subset of paired (N = 62) human hair and (N = 76) tap water samples. Isotope …

With the ongoing growth of gene-based research in recent decades, the possibility of examining changes that have taken place in structures over the course of evolution has become increasingly accessible. One intriguing subject at the forefront of evolutionary research is that of how environmental pressures affect species evolution through epigenetic adaptation. In this paper we present the available molecular components of adaptation to cold environments in two extinct mammals – the woolly mammoth and the Neanderthal. These two species co-existed in similar geographic and environmental European settings during the Middle and Upper Pleistocene and both were direct descendants of African …
Celiac Disease: A Physiological Overview And Possible Future Work With Emphasis On Raman Spectroscopy, Katlyn Curtin Mehne
Celiac Disease: A Physiological Overview And Possible Future Work With Emphasis On Raman Spectroscopy, Katlyn Curtin Mehne
Wayne State University Theses
Celiac Disease is a condition whereby ingesting Gluten causes an autoimmune reaction in the intestines with adverse effects throughout the body. Although statistic analysis estimates that 1% of the general population is affected by this condition, the diagnosis and treatment research lacks in key areas of understanding. This is a summary of current research and physiological information on the impact of Celiac Disease. In the last twenty years, Raman Spectroscopy assisted in diagnosis and treatment of various other ailments. In this case, Raman Spectroscopy can be used to research immunological cells involved in Celiac Disease and further research.
