Background and Objective: In this study a newly developed microprocessor controlled power regulation and thermometry system integrated with a diode laser (805 nm wavelength) was evaluated with respect to temperature distribution, effectiveness of regulation, and ability to predict temperature distributions by computer simulation. Study Design/Materials and Methods: Experiments were performed in gr

A 15N tracing model was developed to analyse nitrous oxide (N2O) dynamics in terrestrial ecosystems, which build on previous tracing models for the quantification of the main mineral nitrogen (N) transformations and soil nitrite (NO2 -) dynamics. The N2O dynamics in the model are directly associated with three NO2 - sub-pools. Four pathways for N2O production in soil were considered in the model:

Early vascular ageing is common in patients with hypertension and increased burden of cardiovascular risk factors, often influenced by chronic inflammation. One aspect of this vascular ageing is arterial stiffening, as measured by increased pulse wave velocity or augmentation index and central pressure. Several studies have indicated that this process starts early in life and that arterial functio

Abstract Thiopental may be used for sedation before intubation in newborn infants. A boy, born at 33 weeks of gestation (gw); birth weight 2435 g, was prescribed thiopental 3 mg/kg before intubation. He developed temporary hypotension and oxygen desaturation, and remained unconscious for longer than expected with a suppressed electroencephalography for 48 h. Serum thiopental concentration was 82,

Objective: To examine how well ultrasound assessed occipitoposterior (OP) position or high sagittal (HS) position in primiparous women with a prolonged first stage of labor predicts a vaginal delivery and the duration of labor. Design: Prospective observational study. Setting. Stavanger University Hospital, a secondary referral center in Norway. Population. 105 primiparous women with prolonged f

Climate-induced phenological shifts may have serious consequences for organisms and populations, but it is challenging to link such shifts to demographic change. Here, we present an overview of current methodological approaches for studying the demographic consequences of phenological shifts, based on a literature survey of 62 studies on diverse taxa. The majority of these studies (66%) were condu

Cadmium and high vitamin A intake are both proposed risk factors for low bone mineral density (BMD), but potential interactions have not been studied. Within the Women's Health in the Lund Area, a population-based study in southern Sweden, we measured retinol in serum among 606 women aged 54-64 y. Data on BMD were measured by DXA at the distal forearm. Parathyroid hormone (PTH), bone alkaline phos

The flavocytochrome cellobiose dehydrogenase (CDH) is a versatile biorecognition element capable of detecting carbohydrates as well as quinones and catecholamines. In addition, it can be used as an anode biocatalyst for enzymatic biofuel cells to power miniaturised sensor-transmitter systems. Various electrode materials and designs have been tested in the past decade to utilize and enhance the dir

Bacterioplankton respiration (BR) may represent the largest single sink of organic carbon in the biosphere and constitutes an important driver of atmospheric carbon dioxide (CO2) emissions from freshwaters. Complete understanding of BR is precluded by the fact that most studies need to assume a respiratory quotient (RQ; mole of CO2 produced per mole of O-2 consumed) to calculate rates of BR. Many

The interaction between monolayers of iron phthalocyanine on a Au(111) support and carbon monoxide and nitric oxide is studied by X-ray photoelectron spectroscopy and density functional theory calculations. We find several carbon monoxide and nitric oxide adsorbate species, and in particular species that bind to the iron ions of the phthalocyanine compound. The formation of phthalocyanine carbonyl

In 2010, the Lithuanian Association of Arhtroplasty was established and on January 1, 2011, initiated a national study of all reoperations after total knee (TKR) and total hip replacement (THR) in Lithuania. The aim of the study was to investigate the revision rates after TKR and THR at two years follow-up.

The steroid hormone metabolite of vitamin D3, 1α,25-dihydroxyvitamin D3 (1,25D3), promotes osteogenic activity and regulates calcium and phosphate metabolism, which are actions regarded as classical vitamin D-regulated functions. Besides its role in these processes, 1,25D3 also seems implicated in the host defense against microbial/pro-inflammatory attacks. Low serum levels of vitamin D3 (vitamin

We developed an analytical theory for the many-body potential of mean force (POMF) between N spheres immersed in a continuum chain fluid. The theory is almost exact for a T polymer solution in the protein limit (small particles, long polymers), where N-body effects are important. Polydispersity in polymer length according to a SchulzFlory distribution emerges naturally from our analysis, as does t

The interaction of C-60 with the Au(111) surface has been investigated using synchrotron radiation-based electron spectroscopy. Resonant photoelectron spectroscopy and autoionization spectroscopy have been used to probe the coupling between the molecule and the substrate. Three distinct high energy spectator Auger features were observed that are only evident for a monolayer of C-60 chemisorbed to
