Forensic isoscapes based on intra-individual temporal variation of O and Pb/Pb in human teeth.

Isotopic signatures used in the georeferencing of human remains are largely fixed by spatially distinct geologic and environmental processes. However, location-dependent temporal changes in these isotope ratios should also be considered when determining an individual's provenance and/or trajectory. Distributions of the relevant isotopes can be impacted by predictable external factors such as climate change, delocalisation of food and water sources and changes in sources and uses of metals.

Refining Stable Oxygen and Hydrogen Isoscapes for the Identification of Human Remains in Mississippi.

Isoscape refinement is an essential component for accurately predicting region-of-origin in forensic investigations involving isotope analysis of unidentified human remains. Stable oxygen (δ O) and hydrogen (δ H) isotopes were measured from 57 tap water samples collected across Mississippi to model refined isoscapes for the state. A tap water conversion equation, δ O =1.

Evaluation of the efficacy of spatiotemporal Pb isoscapes for provenancing of human remains.

Geospatially distributed isotopes (isoscapes) from biogeochemically fractionated processes have been applied in many forensic investigations, such as authentication of food and sourcing of drugs. Provenancing of human remains using isotopes has been hindered by a lack of appropriate isoscapes, by changes in these isoscapes over time, and by various homogenization processes. In this study we create spatiotemporal isoscapes for anthropogenic lead (Pb) for the contiguous United States and Europe using literature data from dated sediments, soils and biological tissues.

Outcomes of hip arthroscopy. A prospective analysis and comparison between patients under 25 and over 25 years of age.

Objective: To compare the results of hip arthroscopy in patients under the age of 25 with those over 25 years.

Design: From March 2006 until May 2010, data were collected on all patients who underwent hip arthroscopy for symptomatic intra-articular hip pathology. The patients were divided into two groups based on age (less than 25 years and over 25 years).

The synthesis of organo-soluble anatase nanocrystals from amorphous titania.

Highly soluble anatase nanocrystals of 4 nm diameter have been prepared by the reaction of amorphous titania with trifluoroacetic acid. The solubility of the nanocrystals is a result of surface bound carboxylate groups, and enables the organic-inorganic hybrid material to be processed from solution to yield high quality coatings and thin-films.

A professional development model for medical laboratory scientists working in the Core Laboratory.

The Division of Pathology and Laboratory Medicine at The University of Texas MD Anderson Cancer Center has implemented a professional development model designed to further the education, expertise, and experiences of medical laboratory scientists in the core laboratory. The professional development model (PDM) has four competency levels: Discovery, Application, Maturation and Expert. All levels require the medical laboratory scientist to learn new skill sets, complete task and projects, and meet continuing education and certification requirements.

Proliferating multicentric reticulohistiocytosis associated with papillary serous carcinoma of the endometrium.

Multicentric reticulohistiocytosis (MRH) is a rare histocytic disease characterized by destructive arthritis in association with classic skin findings. Although MRH is not strictly a paraneoplastic disease, one quarter of cases are malignancy related. We report a case of MRH with an initial remission followed by an acute exacerbation several years later heralding the clinical presentation of endometrial carcinoma.
