A paleopathological survey of ancient Peruvian crania housed at the Peabody museum of archaeology and ethnology at Harvard University, Cambridge, Massachusetts: a special emphasis on scurvy

Unknown Date (has links)
This thesis is a paleopathological survey of ancient Peruvian crania housed at the Peabody Museum of Archaeology and Ethnology at Harvard University, Cambridge, Massachusetts. Chapter one discusses the significance of this research, work prior to this thesis’s formulation, and defines paleopathological and bioarchaeological terms relevant to this thesis. Chapter two presents this thesis’s materials and methods. Of the 196 Peruvian crania in this study sample, 11 case studies are presented. Chapter three reports a case of probable scurvy and likely anemia comorbidity. This case study is accompanied by a critical analysis and review of the literature surrounding scurvy, a detailed macroscopic examination, and a rigorous differential diagnosis process. Chapter four offers cases representing pseudopathology, hematopoietic disease, infectious disease, joint disease, neoplastic disease, trauma, and trauma-induced disease. Chapter five presents a summary of this thesis. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2014. / FAU Electronic Theses and Dissertations Collection

Developmental axial skeletal deformities : baseline study with a zebrafish model

Harden, Jon M. 23 September 2003 (has links)
The aim of this study was to assess sensitivity of early life stage zebrafish to cadmium (Cd). Embryos and larva were exposed to Cd before the formation of skeletal elements. Exposure times were selected to determine whether Cd perturbed developmental processes that lead to skeletal deformities, and to characterize the types of skeletal deformities that occurred. Embryo/larva were exposed to 3μM, 10μM, 30μM, 100μM, 300μM, and 1000μM Cd at 12-36 hours post fertilization (hpf), 36-60hpf, 60-84hpf, and 144-168hpf in one series of experiments. This experiment was conducted at circumneutral pH. A second series of experiments with these same Cd concentrations were also conducted at pH 6 with embryo/larva exposed at 12-36hpf, 36-60hpf, and 60-84hpf. The fish that survived the exposures were raised for 40-60 days whereupon the surviving fish were overdosed with MS222, and X-rayed. The later early life stage fish were more sensitive to Cd toxicity; the chorion appeared to protect the earlier exposed embryos (zebrafish hatch 48-72hpf). Embryo/larva were more resistant to toxicity from dissolved Cd (pH 6) than particulate Cd (circumneutral pH); absence of functional gills during early life stages perhaps explained resistance to dissolved Cd. Notochord lesions (typically lethal within two weeks) occurred when embryos were exposed 12-36hpf. There was no evidence for sensitivity of early life stage zebrafish to Cd induced skeletal deformities that occurred within 40-60 days of Cd exposures. / Graduation date: 2004

Differential Diagnoses Of Temporal Bone Defects And Zygomatic Bone Lesions Found In Fetal And Infant Individuals From The Kellis 2 Cemetery, Dakhleh Oasis, Egypt

Jardine, Brittany A 01 January 2011 (has links)
The Kellis 2 cemetery site within the Dakhleh Oasis, Egypt provides a unique study opportunity due to the large number of infant, perinatal, and fetal individuals that have been recovered. Several of the infant and fetal remains have undiagnosed circular defects on the temporal bone, and others have undiagnosed lesions on the zygomatic bone. Of the 268 individuals under one year of age that have been analyzed from the Kellis 2 cemetery, twentysix individuals have the temporal bone defect and six have the zygomatic bone lesions. A survey of clinical and paleopathological research provided possible pathological conditions that could cause abnormalities such as defects or lesions on the temporal bones or zygomatic bones in the fetal and infant population. For this study, the temporal bone defects and zygomatic bone lesions were macroscopically observed and a descriptive analysis was created. The information garnered from the literature survey was then compared to the individuals from the Kellis 2 cemetery that had the temporal bone defects and zygomatic bone lesions to create a differential diagnosis. A differential diagnosis of the temporal bone defects includes mastoid emissary vein defects and petrosquamous sinus anomalies. A differential diagnosis of the zygomatic bone lesions includes scurvy. Contributing factors may also have been present in order for these defects and lesions to occur. Creating a differential diagnosis of the defects and lesions can provide information on the health, growth, and morbidity of the youngest members of the society related to the Kellis 2 cemetery.
