Hydrolysis of oligosaccharides in the gastrointestinal tract alters their prebiotic effects on probiotic strains.

Unlabelled: Oligosaccharides have been widely used as prebiotics in the food industry, however their properties have been examined in vitro, without considering hydrolysis in the human digestive tract, especially in the small intestine. Here, we hypothesized that the prebiotic effects and utilization efficiency of ingested oligosaccharides would be altered in the colon, as their structures are partially hydrolyzed during digestion. Different types of oligosaccharides were partially degraded during simulated digestion, and digestible monosaccharides were released from the initial substrates.

Anti-Inflammatory, Neurotrophic, and Cytotoxic Oxylipins Isolated from Twigs.

Oxylipins are important biological molecules with diverse roles in human and plants such as pro-/anti-inflammatory, antimicrobial, and regulatory activity. Although there is an increasing number of plant-derived oxylipins, most of their physiological roles in humans remain unclear. Here, we describe the isolation, identification, and biological activities of four new oxylipins, chaenomesters A-D (), along with a known compound (), obtained from twigs.

Bilateral hemispheric changes and language outcomes in chronic left hemisphere stroke.

The role of the right hemisphere in recovery of language function after left hemisphere stroke remains unclear. This prospective study aimed to determine the relationship between bilateral hemispheric changes and severity of aphasia in patients with chronic left hemisphere stroke. Twenty-three patients with left hemisphere stroke with aphasia and 10 healthy control patients underwent high-resolution T1-weighted and diffusion tensor imaging.

Structural and functional improvements due to robot-assisted gait training in the stroke-injured brain.

Robot-assisted gait training (RAGT) can improve walking ability after stroke. Because the underlying mechanisms are still unknown, we analyzed changes in post-stroke injured brains after RAGT. Ten non-ambulatory patients receiving inpatient rehabilitation were examined within 3 months of stroke onset.
