A combined ¹H nuclear magnetic resonance and electrospray ionization-mass spectrometry analysis to understand the basal metabolism of plant-pathogenic Fusarium spp.

Many ascomycete Fusarium spp. are plant pathogens that cause disease on both cereal and noncereal hosts. Infection of wheat ears by Fusarium graminearum and F.

Co-ordinated expression of amino acid metabolism in response to N and S deficiency during wheat grain filling.

Increasing demands for productivity together with environmental concerns about fertilizer use dictate that the future sustainability of agricultural systems will depend on improving fertilizer use efficiency. Characterization of the biological processes responsible for efficient fertilizer use will provide tools for crop improvement under reduced inputs. Transcriptomic and metabolomic approaches were used to study the impact of nitrogen (N) and sulphur (S) deficiency on N and S remobilization from senescing canopy tissues during grain filling in winter wheat (Triticum aestivum).

[Monitoring ischemia-/reperfusion syndrome in abdominal aortic aneurysm--conventional operation versus stent implantation].

From a biochemical point of view, our study corroborates the suggestion that implantation of a stent graft is less invasive than conventional surgery for infrarenal aortic aneurysm. In general, ischemia during open aortic surgery lasts shorter but affects a much greater part of the body than stent implantation. Eventration before, and more pronounced reperfusion following conventional repair cause marked intra-operative increases in TxB2, 6-keto-PGF1 alpha, and sICAM-1 levels.

Plasma palmitate turnover in subjects with thermal injury.

Using a continuous infusion of [1-13C] palmitic acid tracer, plasma palmitate turnover was measured 14 times in nine bandaged, thermally injured adults. Plasma glucose (102 +/- 4 mg/dl), insulin (21 +/- 4 microU/ml), and glucagon (296 +/- 34 pg/ml) levels were significantly elevated compared with values in uninjured controls. Circulating plasma epinephrine (67 +/- 11 pg/ml) and norepinephrine (219 +/- 57 pg/ml) levels were more than twofold their respective control values of 261 +/- 4 pg/ml and 211 +/- 7 pg/ml but less than the previously defined plasma threshold levels for lipolytic effects of these catecholamines as circulating hormones.
