In pelagic ecosystems, the principal source of organic matter is via autotrophic production and the primary sink is through heterotrophic respiration. One would therefore anticipate that there is some degree of linkage between these two compartments. Recent work has shown that respiration in the light is higher than dark respiration. Consequently, many of the methods used to determine respiration
Vascular aging is described as a gradual process involving biochemical, enzymatic, and cellular changes of the vasculature and modification of the signals that modulate them. On the basis of this conception a new pathophysiological model for deeper understanding of cardiovascular risk and its treatment was introduced. The idea of early vascular aging, that is the acceleration of vascular aging see
A 12-bit 125-MHz digital-to-analog converter (DAC) for communication application is designed. It is based on current-steering segmented architecture and modified Q2 random walk switching scheme to obtain 12-bit accuracy. A new voltage swing reduced driver (VSRD) is implemented to promote the dynamic performance. The DAC uses 0.18 µm 1.8 V standard digital CMOS technology. The die area (core) is 2.
This paper is based on the findings of a research work by Abukhader and Jönson (2004a), who discuss the possibilities and limitations of the ties of postponement strategy in food supply chains. They identified the cases/examples (i.e. company cases) of application of postponement across the various categories of foods: frozen, chilled/fresh and long shelf life. The food industry nowadays is in nee
Apolipoprotein E (ApoE), a cholesterol transporter and an immunomodulator, is brain protective after experimental stroke and implicated in brain repair. Here, we study the involvement of ApoE in the restoration of brain function after experimental stroke, by using animal housing conditions that differentially improve recovery after occlusion of the middle cerebral artery occlusion (MCAO). We found
Fixed binary convolutional codes are considered which are simultaneously optimal or near-optimal according to three criteria: namely, distance profiled, free distanced_{ infty}, and minimum number of weightd_{infty}paths. It is shown how the optimum distance profile criterion can be used to limit the search for codes with a large value ofd_{infty}. We present extensive lists of such robustly optim
To confirm findings from a previous pilot study in a larger normal cohort and to study first trimester maternal serum levels of cell-free fetal hemoglobin (HbF) and the heme-scavenger α1-microglobulin (A1M) in patients who subsequently developed preeclampsia (PE), furthermore to evaluate these proteins as predictive biochemical markers of PE.
Objective: To assess whether a genetic risk score that was previously shown to be associated with myocardial infarction and coronary artery disease is also associated with markers of carotid atherosclerosis. Design: A total of 4022 middle-aged subjects from the general Swedish population were genotyped and individually assigned a genetic risk score based on 13 single-nucleotide polymorphisms (SNPs
OBJECTIVE: /st> To investigate the effect of tumour necrosis factor (TNF) antagonist treatment of patients with rheumatoid arthritis (RA) on sick leave (SL) and disability pension (DP) in a population-based setting in southern Sweden. METHODS: /st> All patients with RA in the South Swedish Arthritis Treatment Group register living in the county of Skåne (population 1.2 million), who started their
