BACKGROUND: Vegetable growers in Arctic areas usually must rely on market strategies based on regional origin and product quality. Swede roots (rutabaga) were grown in a phytotron to investigate the effect of high latitude light conditions on sensory quality and some health and sensory-related compounds. Experimental treatments included modifications of 24 h natural day length (69° 39' N), by moving plants at daily intervals to dark chambers with either no light, fluorescent growth light and/or low intensity photoperiod extension...

BACKGROUND: The upper half of the human small intestine, known as the jejunum, is the primary site for absorption of nutrient-derived carbohydrates, amino acids, small peptides, and vitamins. In contrast to the colon, which contains 10(11)-10(12) colony forming units of bacteria per ml (CFU/ml), the normal jejunum generally ranges from 10(3) to 10(5) CFU per ml. Because invasive procedures are required to access the jejunum, much less is known about its bacterial microbiota. Bacteria inhabiting the jejunal lumen have been investigated by classical culture techniques, but not by culture-independent metagenomics...

BACKGROUND: The management strategy for patients with atrial fibrillation (AF) is often very complex, electrical cardioversion (EC) being often used to restore sinus rhythm in those patients. The increased risk of thromboembolic complications was lowered using anticoagulation therapy. Usually, the anticoagulation was achieved using vitamin K antagonists (VKAs), but over the last years we witnessed a wide implementation of the novel oral anticoagulants (NOACs). STUDY QUESTION: Study question was to compare the efficacy of NOACs versus VKAs in patients undergoing elective EC for persistent AF, by assessing the presence of left atrial spontaneous contrast and left atrial thrombi (LACS), as well as the occurrence of the thromboembolic events in the first month after the procedure...

Tuberculosis (TB) presents a serious health problem with approximately one-third of the world's population infected with Mycobacterium tuberculosis in a latent state. Experience from the pre-antibiotic era and more recent clinical studies have established a beneficial role of sunlight and vitamin D in patients with TB. At the same time, experimental data have shown that Th1 cells through production of IFNγ are crucial for cathelicidin release by macrophages, bacterial killing, and containment of M. tuberculosis in granulomas...

Previous research has shown that cows fed ≥24% of the diet dry matter (DM) as field peas decreased milk yield as well as concentration and yield of milk protein, possibly due to reduced DM intake and limited supply of Lys and Met. Twelve multiparous and 4 primiparous lactating Holstein cows were randomly assigned to 1 of 4 diets in a replicated 4 × 4 Latin square design. The diets contained (DM basis) 34.8% corn silage, 15.2% grass-legume silage, 5.9% roasted soybean, 2.4% mineral-vitamin premix, 2.0% alfalfa pellets, and either (1) 36% ground corn, 2...
