Photorespiration is a process that competes with photosynthesis, in which Rubisco oxygenates, instead of carboxylates, its substrate ribulose 1,5-bisphosphate. The photorespiratory metabolism associated with the recovery of 3-phosphoglycerate is energetically costly and results in the release of previously fixed CO(2) . The ability to quantify photorespiration is gaining importance as ...

Quantum dots (QD) are powerful labels for probing diffusion and interaction dynamics of proteins on the single molecule level in living cells. Protein cross-linking due to multifunctional QD strongly affects these properties. This becomes particularly critical when labeling interactions partners with QDs for interrogating the dynamics of complexes. We have ...

Adequate nutritional support is a major challenge in head trauma patients, since malnutrition cannot be reversed by standard enteral nutrition. We hypothesized that an oligomeric formula could improve nutritional status by restoring intestinal trophicity. Eighteen male Sprague-Dawley rats (300-330 g) underwent gastrostomy (D-7) and Traumatic Brain injury (TBI) by hydraulic ...

Abstract We argue for a morphofunctional approach to emotion modeling that can also aid the design of adaptive embodied systems. By morphofunctionality we target the online change in both structure and function of a system, and relate it to the notion of physiology and emotion in animals. Besides the biological ...

Elucidating the molecular mechanisms of selective ligand recognition by proteins is a long-standing problem in drug discovery. Rapid increase in the availability of three-dimensional protein structural data indicates that a data-driven approach for finding the rules that govern protein-ligand interactions is increasingly attractive. However, this approach is not straightforward because ...

Objective: In the last six years, several studies reported a positive association between TSH and risk of papillary cancer. The rationale of this finding is based on a stimulatory action exerted by TSH on thyroid cell proliferation and/or progression of a pre-existing papillary carcinoma. To validate this hypothesis, we perform ...

Plant pathogenic bacteria utilize complex signalling systems to control the expression of virulence genes at the cellular level and within populations. Quorum sensing (QS), an important intercellular communication mechanism, is mediated by different types of small molecules, including N-acyl homoserine lactones (AHLs), fatty acids and small proteins. AHL-mediated signalling systems ...
