Design and evaluation of microencapsulated systems containing extract of whole green coffee fruit rich in phenolic acids

Publication date: Available online 11 October 2019Source: Food HydrocolloidsAuthor(s): Wanessa Costa Silva Faria, Edemilson Cardoso da Conceição, Waldenia de Melo Moura, Wander Miguel de Barros, Attilio Converti, Neura BragagnoloAbstractThe optimal conditions to microencapsulate green coffee (Coffea canephora) fruit extract (GCFE) by spray drying using a maltodextrin (MD)-gum Arabic (GA) mixture as carrier material were selected. For this purpose, a Central Composite Rotational Design was applied to investigate the combined effects of the MD percentage in the mixture and the extract-to-carrier agent mass ratio (mE/mC) as the independent variables. These effects were modelled by second-order polynomial models on several responses, namely process yield, encapsulation efficiency, water activity, losses of reducing capacity, caffeic acid, caffeine, trigonelline, 5-O-caffeoilquinic acid (5-CQA) from microcapsules (MCs) and 5-CQA retention after 180-days storage. The statistically significant effects were then submitted to more in-depth analysis by Response Surface Methodology. The highest process yield was obtained using a MD percentage of 80% and a mE/mC ratio of 1:1.5 (w/w). Both microencapsulated and non-encapsulated GCFE showed good stability during the accelerated stability study performed at 40 °C for 180 days. Surface morphology and particle size distribution of GCFE-loaded MCs were shown to be suitable for use in the food industry.Graphical abstract

This study aims to examine the effectiveness of the postural treatment of the Mézières method on elite rhythmic gymnastics athletes with low back pain. DESIGN: Double-blind, randomized, controlled trial. SETTING: The sports hall of "Puente Tocinos," Murcia, Spain. PARTICIPANTS: Ninety gymnastics athletes were randomized into 2 parallel groups (intervention: n = 39; control: n = 51), of whom 98.9% were women (women = 89; man = 1). INTERVENTION: The Mézières method postural therapy was implemented. It lasted about 60 minutes in repeated sessions of 2 to 3 meetings per wee...

CONCLUSIONS: Delayed activation of the VM registered in females determines an increase in anterior shear force, which is an important risk factor for incurring an ACL injury. This testing protocol becomes adequate for the screening of high-risk athletes and for targeting interventions to specific imbalances that may increase injury risk.

Authors: Fyock M, Cortes N, Hulse A, Martin J Abstract Clinical Scenario: Patellofemoral pain (PFP) is a common knee injury in recreational adult runners, possibly caused by faulty mechanics. One possible approach to reduce this pain is to retrain the runner's gait. Current research suggests that no definitive gold standard treatment for PFP exists. Gait retraining utilizing visual feedback may reduce PFP in both the short and long term. Clinical Question: In adult runners diagnosed with PFP, does gait retraining with real-time visual feedback lead to a decrease in pain? Summary of Key Findings: A literature search...

We carry out eight configurations, mono-, di-, tri-, tetra-, penta-, hexa-, hepta-, and octavacancies by using the density-functional-theory calculations (DFT). We calculate formation and dissociation energies to analyze the stability by finding the magic numbers. Magic numbers are the number of vacancy belonging to stable configurations. We find that di-, tetra-,...

Authors: Gabella G Abstract All the cells of rat detrusor muscle fall into one of five ultrastructural types: muscle cells, fibroblasts, axons and glia, and vascular cells (endothelial cells and pericytes). The tissue is ~79% cellular and 21% non-cellular. Muscle cells occupy 72%, nerves ~4% (1/3 axons, 2/3 glia), and fibroblast>3% of space. Muscle cells (up to 6 µm across and ~600 µm long, packed to almost 100,000 per mm2) have surface-to-volume ratio of 2.4 µm2/µm3 ~93% of cell volume is contractile apparatus, 3.1% mitochondria and 2.5% nucleus. Cell profiles are irregular but section...
