Ketoacidosis - Where Do the Protons Come From?

In extreme conditions ketosis can progress to ketoacidosis, a dangerous and potentially life-threatening condition. Ketoacidosis is most common in new or poorly treated type 1 diabetes. The acidosis is usually attributed to the 'acidic' nature of the ketone bodies (acetoacetate, 3-hydroxybutyrate, and acetone).

Variability and bias between magnetoencephalography systems in non-invasive localization of the primary somatosensory cortex.

Objectives: Magnetoencephalography (MEG) provides functional neuroimaging data for pre-surgical planning in patients with epilepsy or brain tumour. For mapping the primary somatosensory cortex (S1), MEG data are acquired while a patient undergoes median nerve stimulation (MNS) to localize components of the somatosensory evoked field (SEF). In clinical settings, only one MEG imaging session is usually possible due to limited resources.

Historical analysis of oil and gas well plugging in New York: is the regulatory system working?

The aim of this work was to evaluate New York State's regulatory program for plugging inactive oil and gas wells. Analysis of reports from the Division of Mineral Resources, Department of Environmental Conservation, reveals that three-fourths of the state's abandoned oil and gas wells were never plugged. Inadequate enforcement efforts have resulted in steady increases of unplugged oil and gas wells abandoned since 1992.

Instrumental neutron activation analysis of archaeological ceramics: scale and interpretation.

Instrumental neutron activation analysis has become a standard technique for the study of the production and distributional patterns of archaeological pottery. Questions once framed within the context of long distance exchange are now focused on issues of subregional and even intrasite levels. The increasing specificity at which these questions are poised requires a high level of analytical precision as we seek to observe statistically and archaeologically significant differences among groups of pottery produced from geographically closely spaced resources or the compositional differences that arise from production behaviors of the producers of the pottery.
