Weight loss predictability by plasma metabolic signatures in adults with obesity and morbid obesity of the DiOGenes study

Objective: Aim is to predict successful weight loss by metabolic signatures at baseline and to identify which differences in metabolic status may underlie variations in weight loss success. Methods: In DiOGenes, a randomized, controlled trial, weight loss was induced using a low calorie diet (800 kcal) for 8-weeks. Men (N5236) and women (N5431)...

Distinct defects in collagen microarchitecture underlie vessel-wall failure in advanced abdominal aneurysms and aneurysms in Marfan syndrome

An aneurysm of the aorta is a common pathology characterized by segmentalweakeningof the artery.Althoughit isgenerally accepted that the vessel-wall weakening is caused by an impaired collagen metabolism, a clear association has been demonstrated only for rare syndromes such as the vascular type Ehlers-Danlos syndrome. Here we show that vessel...

IPP-rich milk protein hydrolysate lowers blood pressure in subjects with stage 1 hypertension a randomized controlled trial

Background. Milk derived peptides have been identified as potential antihypertensive agents. The primary objective was to investigate the effectiveness of IPP-rich milk protein hydrolysates (MPH) on reducing blood pressure (BP) as well as to investigate safety parameters and tolerability. The secondary objective was to confirm or falsify ACE...

Safety evaluation of an IPP tripeptide-containing milk protein hydrolysate

Tensguard™ is a milk protein hydrolysate containing the lactotripeptide IPP. It is derived from cow's milk, which is present in the human diet and has a safe history of consumption. The final Tensguard™ product, a supplement or a functional food ingredient, is intended for use by people who want to follow a healthy diet and lifestyle in order to...

Efficient degradation of gluten by a prolyl endoprotease in a gastrointestinal model: Implications for coeliac disease

Background: Coeliac disease is caused by an immune response to gluten. As gluten proteins are proline rich they are resistant to enzymatic digestion in the gastrointestinal tract, a property that probably contributes to the immunogenic nature of gluten. Aims: This study determined the efficiency of gluten degradation by a post-proline cutting...

Bioavailability of tryptophan from a single oral dose of a trytophan-enriched peptide mixture in healthy men

The aim of the study was to investigate the bioavailability of tryptophan (Trp) from a Trp-enriched peptide mixture in healthy men. A second objective was to investigate the effect of this Trp-enriched protein hydrolysate on potential parameters of serotonergic activity. serum serotonim melatonin and prolactin and urinary 5-hydroxyindol-acetic...

Allosteric modulation and constitutive activity of fusion proteins between the adenosine A1 receptor and different 351Cys-mutated Gi α-subunits

We studied fusion proteins between the human adenosine A1 receptor and different 351Cys-mutated Gi1 α-subunits (A1-Giα) with respect to two important concepts in receptor pharmacology, i.e. allosteric modulation and constitutive activity/inverse agonism. The aim of our study was twofold. We first analysed whether such fusion products are still...

A pilot study to investigate effects of inulin on Caco-2 cells through in vitro metabolic fingerprinting

Metabolic fingerprints are novel measurement tools to evaluate the biochemical status of a living organism by using 1H NMR and multivariate data analysis (MVDA). In this way, a quick evaluation of changes in health or diseased state can be made, reflected in alterations of metabolic patterns. Normally, metabolic finger-printing is based on in...

Covalent binding of nitrogen mustards to the cysteine-34 residue in human serum albumin

Covalent binding of various clinically important nitrogen mustards to the cysteine-34 residue of human serum albumin, in vitro and in vivo, is demonstrated. A rapid method for detection of these adducts is presented, based on liquid chromatography-tandem mass spectrometry analysis of the adducted tripeptide Cys*-Pro-Phe after digestion of the...

Human granzyme B mediates cartilage proteoglycan degradation and is expressed at the invasive front of the synovium in rheumatoid arthritis

Objective. To investigate the cartilage-degrading capacity of granzyme B and the presence of granzyme B-positive cells at sites of erosion in the rheumatoid synovium. Methods. Granzyme B was added to [3H]proline/[35S]sulphate-labelled cartilage matrices and to cartilage explants. Proteoglycan degradation was assessed by the release of 35S and...

Identification and genetic analysis of a common molecular variant of histidine-rich glycoprotein with a difference of 2KD in apparent molecular weight

Two forms of histidine-rich glycoprotein (HRG) were detected on SDS-PAGE by silver staining and immunoblotting after isolation of the protein from pooled plasma using immune-affinity chromatography followed by chromatography with heparin-Sepharose. Both forms were single-chain molecules and the apparent molecular weights of form 1 and form 2...
