Control of OSA in a patient with CCC of soft palate using bilateral hypoglossal nerve stimulation.

Patients with complete concentric collapse of the redropalatal airway are excluded from unilateral hypoglossal nerve stimulation. This case report shows good control of OSA in a patient with CCC with a new bilateral hypoglossal nerve stimulator.

Anthocyanins and their physiologically relevant metabolites alter the expression of IL-6 and VCAM-1 in CD40L and oxidized LDL challenged vascular endothelial cells.

Scope: In vitro and in vivo studies suggest that dietary anthocyanins modulate cardiovascular disease risk; however, given anthocyanins extensive metabolism, it is likely that their degradation products and conjugated metabolites are responsible for this reported bioactivity.

Methods And Results: Human vascular endothelial cells were stimulated with either oxidized LDL (oxLDL) or cluster of differentiation 40 ligand (CD40L) and cotreated with cyanidin-3-glucoside and 11 of its recently identified metabolites, at 0.1, 1, and 10 μM concentrations.

Phenolic metabolites of anthocyanins modulate mechanisms of endothelial function.

Anthocyanins are reported to have vascular bioactivity, however their mechanisms of action are largely unknown. Evidence suggests that anthocyanins modulate endothelial function, potentially by increasing nitric oxide (NO) synthesis, or enhancing NO bioavailability. This study compared the activity of cyanidin-3-glucoside, its degradation product protocatechuic acid, and phase II metabolite, vanillic acid.

Methods for isolating, identifying, and quantifying anthocyanin metabolites in clinical samples.

The metabolic fate of anthocyanins until recently was relatively unknown, primarily as a result of their instability at physiological pH and a lack of published methods for isolating and identifying their metabolites from biological samples. The aim of the present work was to establish methods for the extraction and quantification of anthocyanin metabolites present in urine, serum, and fecal samples. 35 commercial and 10 synthetic analytes, including both known and predicted human and microbial metabolites of anthocyanins, were obtained as reference standards.

Human metabolism and elimination of the anthocyanin, cyanidin-3-glucoside: a (13)C-tracer study.

Background: Evidence suggests that the consumption of anthocyanin-rich foods beneficially affects cardiovascular health; however, the absorption, distribution, metabolism, and elimination (ADME) of anthocyanin-rich foods are relatively unknown.

Objective: We investigated the ADME of a (13)C5-labeled anthocyanin in humans.

Design: Eight male participants consumed 500 mg isotopically labeled cyanidin-3-glucoside (6,8,10,3',5'-(13)C5-C3G).

Simultaneous pasteurization and homogenization of human milk by combining heat and ultrasound: effect on milk quality.

The combination of ultrasound and heat (thermoultrasound) is an emerging food preservation technique that retains higher quantities of bioactive components compared with current thermal pasteurization practice, but has not yet been assessed for pasteurizing human milk. Artificially contaminated human milk samples were treated with ultrasound (20 kHz, 150 watts) with and without heating. The retention of four human milk proteins was quantified by biochemical assay and laser scattering particle sizing was used to determine the extent of homogenization.

Design and characterization of a human milk product for the preterm infant.

Background: It is necessary to fortify human milk to promote optimal growth of the very preterm infant. However, the addition of non-human milk components to human milk is not ideal because of the risk of feeding intolerance and necrotizing enterocolitis. Human milk products (HMP) are an alternative to commercially available fortifiers, but their preparation is likely to result in modifications to the qualities of human milk.

Retention of the immunological proteins of pasteurized human milk in relation to pasteurizer design and practice.

Pasteurizing donor human milk inactivates bacteria that may be of concern to the preterm infant. However, current practice for Holder Pasteurization (62.5 degrees C for 30 min) is detrimental to the bioactivity of human milk.

A method for standardizing the fat content of human milk for use in the neonatal intensive care unit.

Background: Accurately targeting the nutritional needs of the early preterm infant is challenging when human milk is used due to the natural variation in energy composition. The purpose of this study was to develop and evaluate a simple method for reducing the variation in fat and energy content of human milk prior to fortification such that the infant receives a diet of known composition.

Methods: Milk was centrifuged at low speed to concentrate the fat into a cream layer and a predetermined volume of skim milk is removed to meet a specific fat concentration.
