Neurohumoral and mechanical factors in the modulation of left ventricular mass

The goals for the research were to define, describe, and study those neuroendocrine and mechanical mechanisms that may play a role in the initiation and maintenance of an increase in, or cause regression of, the mass of the left ventricle. Dynamic changes in heart mass have been observed to occur in man and animals: (1) enlargement of the heart is frequently encountered in patients with hypertensive disease, and (2) decrease in heart mass has been reported for men exposed to prolonged space flight. The basic physiologic processes which may explain how these changes occur, and the effects of gain or loss of myocardial mass on cardiac performance were considered significant questions to be answered for the benefit of the National Aeronautics and Space Administration

Human Decomposition Ecology at the University of Tennessee Anthropology Research Facility

The University of Tennessee Anthropology Research Facility (ARF) is well known for its unique history as a site of human decomposition research in a natural environment. It has been integral to our understanding of the processes of human decomposition. Over the last 30 years 1,089 bodies have decomposed at this 1.28 acre facility, producing a density of 850 corpses per acre of land. This project evaluated the abiotic and biotic characteristics of the soil exposed to various levels of human decomposition in order to determine the effect on the physicochemical properties and the indigenous bacterial communities. Specifically, 75 soil samples were taken to determine abiotic properties. A biological matrix was generated for the 40 samples inside the facility based on sequencing of the 16S rDNA gene. The identified taxonomy was evaluated for differences among decomposition bins and taxa. Results of the abiotic soil properties demonstrated few differences among the predefined bins of decomposition density. Significant differences were observed between samples inside the facility to the negative control, and to those samples taken below actively decomposing corpses. When taken together, the abiotic data demonstrated a temporal shift away from control, with the greatest deviation at 18 to 24 months. After which time, the samples became more similar to control samples. Similarly, the biotic data remained concordant with the abiotic data, but demonstrated significant differences between the areas of high decomposition to those with no history of decomposition. The high decomposition bins were marked by high levels of chemoorganotrophic and sulfate-reducing bacteria, and a reduction in Acidobacteria, indicating a change in the community of underlying bacteria in response to carcass enrichment and ammonification of the soil. Thirty years of decomposition research at the ARF has forced a shift in the underlying bacterial community in response to the enrichment of the soil with increased nitrogen and carbon-containing compounds. The baseline data presented in this work provides a control dataset for further exploration regarding the biogeochemical relationships among microbial organisms, soil characteristics, and cadaver decomposition. Within this relationship exists the potential for developing new models relating to postmortem interval estimation and clandestine grave location

Wonder-Working Providence of Sions Saviour in New England 1628-1651

Late in the year 1653, but under date of 1654, Nathaniel Brooke, a London publisher, at the Angel in Cornhill, brought out a small octavo book of two hundred and thirty-six pages, entitled A History of New-England, from the English planting in the Yeere 1628 untill the Yeere 1652, etc. The title, inexact in any case, for the book is rather a history of Massachusetts than of all New England, was evidently affixed by the publisher. His advertisements show that at one time he thought of giving the book the title Historicall Relation of the First Planting of the English in New England in the Year 1628 to the Year 1653 and all the Materiall Passages happening there. But many reiterations in the text of the book show that the author\u27s own title for his production was that which appears in the running headlines of the printed book, and by which it has been generally known, The Wonder-working Providence of Sion\u27s Saviour in New England. The author\u27s name nowhere appears in the book

Distribution of heavy metals in the different parts of Cerithidea obtusa and the relationships between metal distribution and allometric parameters of the snail

The intertidal gastropod, Cerithidea obtusa were obtained from Bako and Sematan (Sarawak) and Deralik (Perak). Besides the shell, the snails were dissected into five different soft tissues. The soft tissues and the shell were then analysed for heavy metals. It was found that the highest concentrations of Cu (112 - 178 μg/g dw) and Zn (117 - 161 μg/g dw) were found in the tentacle; the highest concentrations of Cd (4.41 - 5.37 μg/g dw), Pb (53.2 - 63.8 μg/g dw) and Ni (26.1 - 27.9μg/g dw) were found in the shell. On the other hand, the highest Fe concentrations (910 - 2921 μg/g dw) were found in the operculum. The Spearman’s correlation coefficient and multiple stepwise linear regression also revealed that the allometric parameters can influence the distribution of heavy metals in some of the different parts. From the present findings indicated that the heavy metals accumulated by the C. obtusa from the environment might affect its physical growth, which was shown by the negative correlations found between the metals in the different parts with the allometric parameters
