––Estimating local deer populations is an important consideration for deer managers. Shelled corn is commonly used to attract white-tailed deer (Odocoileus virginianus) to infrared-triggered camera survey sites. The addition of mineral formulations may increase deer visitation. We evaluated the effect of four mineral formulations on deer visitation at two study areas in Tennessee. Mineral formu...

Our group has devoted to the application of Nuclear Magnetic Resonance (NMR) spectroscopy and Nuclear Magnetic Resonance Imaging (MRI) to basic science and clinical problems of bone mineral and matrix, and to the diseases associated with bone. NMR spectroscopy provides an analysis of the ionic composition and structure of the mineral crystals and matrix, i.e., the properties of bone as a materi...

background: osteoporosis is a major public health concern around the world. it has been shown that bone mineral den­sity is correlated to anthropometric measures like height and weight, but this association may vary depending on ethnic and environmental factors. the aim of this study was to identify probable relations between anthropometric measures and bone mineral density. methods: in this po...

The prebiotic significance of laboratory experiments that study the interactions between oligomeric RNA and mineral species is difficult to know. Natural exemplars of specific minerals can differ widely depending on their provenance. While laboratory-generated samples of synthetic minerals can have controlled compositions, they are often viewed as "unnatural". Here, we show how trends in the in...

A heavy media column is used for the separation of the mineral fractions of a sample. Thus the directly weighed per cent of the mineral composition of the rock or ore sample is accomplished. ttre teihnique may be applied to the concentration of a particular species, e,ren i.r trace amounts, for further mineralogical studies or for practical commercial metallurgical mineral beneficiation purposes'

A survey was conducted in certain parts of Haryana to record the prevalence of micro mineral deficiency in buffaloes. The prevalence of soil Cu, Co, Zn and Fe deficiency was 55.26%, 6.9%, 59.12% and 7.89% respectively. While that of fodder Cu, Co, Zn and Fe was 60.64%, 6.7%, 61.22% and 11.37% respectively. The overall prevalence of serum Cu, Co, Zn and Fe deficiency in Haryana was 59.2%, 19.1%,...

1. Serial measurements of total body calcium have been made by prompt gamma-neutron activation analysis in 13 patients with inflammatory bowel disease over a mean period of 23 months. Changes in spinal trabecular bone mineral density and radial shaft bone mineral content were also assessed by using quantitative computed tomography and single photon absorptiometry, respectively. 2. The mean annu...

BACKGROUND AND PURPOSE Established methods of assessing bone mineral density are associated with additional radiation exposure to the patient. In this study, we aimed to validate a method of assessing bone mineral density in routine multidetector row CT of the lumbar spine. MATERIALS AND METHODS In 38 patients, bone mineral density was assessed in quantitative CT as a standard of reference an...

OBJECTIVE: We aimed to analyze the applicability of a fracture risk assessment tool for the prediction of osteoporotic fractures in middle-aged and elderly healthy Chinese adults. METHODS: A standard questionnaire was administered, and bone mineral density was measured in residents visiting the Dongliu Street Community Health Service Center. Paired t-tests were used to compare the FRAX-based ...
