The crystal structure of iron, the major component Earth's inner core (IC), is unknown under IC high pressure (P) (3.3--3.6 Mbar) and temperature (T) (5000--7000 K). Experimental theoretical data on phase diagram iron at these extreme PT conditions are contradictory. Applying quasi-ab initio ab molecular dynamics we computed free energies body-centered cubic (bcc), hexagonal close-packed (hcp),...

BACKGROUND Informal carers of persons with dementia are in contact with numerous healthcare professionals (HCP) in a complex healthcare system. Successful collaboration between the parties involved appears to be essential for good dementia care. Thus, we investigated the perceptions of both HCP and informal carers regarding successful collaboration and sought to describe obstacles and facilitat...

Bacillus subtilis undergoes a highly distinctive division during spore formation. It yields two unequal cells, the mother cell and the prespore, and septum formation is completed before the origin-distal 70% of the chromosome has entered the smaller prespore. The mother cell subsequently engulfs the prespore. Two different probes were used to study the behavior of the terminus (ter) region of t...

The hydrophobin EAS from the fungus Neurospora crassa forms functional amyloid fibrils called rodlets that facilitate spore formation and dispersal. Self-assembly of EAS into fibrillar rodlets occurs spontaneously at hydrophobic:hydrophilic interfaces and the rodlets further associate laterally to form amphipathic monolayers. We have used site-directed mutagenesis and peptide experiments to ide...

The growth dynamics of extraradical mycelium and spore formation of 14 "Rhizophagus" isolates from different sites in Argentina were evaluated under monoxenic conditions. A modified Gompertz model was used to characterize the development of mycelium and spores for each isolate under the same conditions. The lag time, maximal growth rate and total quantity of both extraradical hyphae and spores ...

CONTEXT Influenza is a major cause of patient morbidity. Mandatory influenza vaccination of healthcare personnel (HCP) is increasingly common yet has uncertain clinical impact. This study systematically examines published evidence of the benefits and harm of influenza vaccine mandates. EVIDENCE ACQUISITION MEDLINE, Embase, the Cochrane Library, Cumulative Index to Nursing and Allied Health Li...

INTRODUCTION Recently, a non-invasive, continuous ventricular stroke volume monitoring system using skin electrodes has been developed. In contrast to impedance-based methods, the new technique (ventricular field recognition) enables measurement of changes in ventricular volume. A prototype using this new method was built (the hemologic cardiac profiler, HCP) and validated against a reference m...

BACKGROUND In Colombia, HIV and AIDS constitute one of the major diseases of high cost to the health system, making necessary health risk management of patients with this disease through comprehensive health care programs with their respective evaluation of results. OBJECTIVE To evaluate the relative cost-effectiveness of a care program for patients with HIV/AIDS affiliated to a health insure...

Objective(s):Mesenchymal stem cells (MSCs) derived from Wharton’s jelly (WJ-MSCs) are now much more appealing for cell-based infertility therapy. Hence, WJ-MSCs differentiation toward germ layer cells for cell therapy purposes is currently under intensive study. Materials and Methods: MSCs were isolated from human Wharton’s jelly and treated with BMP4, retinoic acid (RA) or co-cultured on huma...

In previous studies we showed that a chronic colitis associated with a Thl T cell response can be induced by the rectal administration of the haptenizing reagent 2,4,6-trinitrobenzene sulfonic acid (TNBS). We report here that oral administration of haptenized colonic proteins (HCP) before rectal administration of TNBS effectively suppresses the ability of the latter to induce colitis. This supp...
