Investigations on the Maillard Reaction of Dextrins during Aging of Pilsner Type Beer.
J. Agric. Food Chem.
PUBLISHED: 09-30-2014
Show Abstract
Hide Abstract
Although Maillard reaction plays a pivotal role during preparation of food, only few investigations concerning the role of carbohydrate degradation in beer aging have been carried out. The formation of Maillard specific precursor structures and their follow-up products during degradation of low molecular carbohydrate dextrins in the presence of proline and lysine was studied in model incubations and in beer. Twenty-one ?-dicarbonyl compounds were identified and quantitated as reactive intermediates. The oxidative formation of 3-deoxypentosone as the precursor of furfural from oligosaccharides was verified. N-Carboxymethylproline and N-formylproline were established as novel proline derived Maillard advanced glycation end products. Formation of N-carboxymethylproline and furfural responded considerably to the presence of oxygen and was positively correlated to aging of Pilsner type beer. The present study delivers an in-depth view on the mechanisms behind the formation of beer relevant aging parameters.

Cadmium accumulation in chloroplasts and its impact on chloroplastic processes in barley and maize.

Hide Abstract
Data on cadmium accumulation in chloroplasts of terrestrial plants are scarce and contradictory. We introduced CdSO4 in hydroponic media to the final concentrations 80 and 250 ?M and studied the accumulation of Cd in chloroplasts of Hordeum vulgare and Zea mays. Barley accumulated more Cd in the chloroplasts as compared to maize, whereas in the leaves cadmium accumulation was higher in maize. The cadmium content in the chloroplasts of two species varied from 49 to 171 ng Cd/mg chlorophyll, which corresponds to one Cd atom per 728-2,540 chlorophyll molecules. Therefore, Mg(2+) can be substituted by Cd(2+) in a negligible amount of antenna chlorophylls only. The percentage of chloroplastic cadmium can be estimated as 0.21-1.32 % of all the Cd in a leaf. Photochemistry (F v/F m, ?PSII, qP) was not influenced by Cd. Non-photochemical quenching of chlorophyll-excited state (NPQ) was greatly reduced in barley but not in maize. The decrease in NPQ was due to its fast relaxing component; the slow relaxing component rose slightly. In chloroplasts, Cd did not affect mRNA levels, but content of some photosynthetic proteins was reduced: slightly in the leaves of barley and heavily in the leaves of maize. In all analyzed C3-species, the effect of Cd on the content of photosynthetic proteins was mild or absent. This is most likely the first evidence of severe reduction of photosynthetic proteins in leaves of a Cd-treated C4-plant.

Effect of weight loss on serum pigment epithelium-derived factor levels.
Eur. J. Clin. Invest.
PUBLISHED: 02-14-2011
Show Abstract
Hide Abstract
Cumulating evidence suggests that the broadly acting neurotrophic pigment epithelium-derived factor is associated with visceral adiposity, the metabolic syndrome, diabetes and exerts beneficial effects on atherosclerosis. To further elucidate the relationship between pigment epithelium-derived factor and metabolic perturbations characteristic of obesity, we examined the effect of pronounced weight loss on serum levels of pigment epithelium-derived factor.

Hide Abstract
Perforated diverticulitis with advanced generalized peritonitis is a life-threatening condition requiring emergency operation. To reduce the rate of colostomy formation, a new treatment algorithm with damage control operation, lavage, limited closure of perforation, abdominal vacuum-assisted closure (VAC; V.A.C.), and second look to restore intestinal continuity was developed.

Division of the short gastric vessels during laparoscopic Nissen fundoplication: clinical and functional outcome during long-term follow-up in a prospectively randomized trial.

Hide Abstract
Although the first laparoscopic Nissen fundoplication was performed almost two decades ago, division of the short gastric vessels is still controversially discussed. The aim of this prospectively randomized trial was to evaluate the clinical and functional outcome following laparoscopic Nissen fundoplication with division versus saving of the short gastric vessels during short- and long-term follow-up.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
