The Influence of Temperature, Storage Conditions, pH, and Ionic Strength on the Antioxidant Activity and Color Parameters of Rowan Berry Extracts.

Recent trends in the food industry combined with novel methods in agriculture could transform rowan into a valuable raw material with potential technological applications. Thus, the aim of this research was to investigate the content of bioactive compounds in its fruits and to assess the color and antioxidant stability of the extracts prepared from such fruits during various thermal treatments and at different pH and ionic strength values. Various spectrophotometric methods, HPLC, and capillary electrophoresis were used to quantify the concentrations of bioactive compounds-polyphenols, carotenoids, organic acids, and to assess antioxidant activity and color.

In vitro bioaccessibility of macular xanthophylls from commercial microalgal powders of and .

The bioaccessibility of the major carotenoids present in two commercial microalgal supplements in powder form was investigated through a standardized in vitro digestion method. The dried biomass of contained β-carotene (36.8 mg/100 g) and zeaxanthin (20.

A Brief Overview of Dietary Zeaxanthin Occurrence and Bioaccessibility.

As it exhibits no provitamin A activity, the dietary intake of zeaxanthin is not considered essential. However, its contribution to ocular health has long been acknowledged. Numerous publications emphasize the importance of zeaxanthin alongside lutein in ocular diseases such as cataracts and age-related macular degeneration which constitute an important health concern, especially among the elderly.

How to perform a late explantation of a Sapien XT transcatheter aortic prosthesis.

Starting as a therapeutically option for high-risk surgical patients with degenerative aortic valve stenosis, the transcatheter aortic valve implantation method is probably going to become the method of choice for this pathology also in younger and low-risk patients. As bioprosthesis are prone to degeneration, requiring a redo procedure, whenever a valve in valve procedure is contraindicated, a surgical valve replacement will become necessary. We describe a simple surgical method for explantation of a Sapien XT prosthesis that was implanted 7 years previously in a calcified aortic valve.

Sea Buckthorn Oil as a Valuable Source of Bioaccessible Xanthophylls.

Sea buckthorn oil, derived from the fruits of the shrub, also termed seaberry or sandthorn, is without doubt a strikingly rich source of carotenoids, in particular zeaxanthin and β-carotene. In the present study, sea buckthorn oil and an oil-in-water emulsion were subjected to a simulated gastro-intestinal in vitro digestion, with the main focus on xanthophyll bioaccessibility. Zeaxanthin mono- and di-esters were the predominant carotenoids in sea buckthorn oil, with zeaxanthin dipalmitate as the major compound (38.

Perioperative Patient Blood Management Programme. Multidisciplinary recommendations from the .

Patients with untreated anaemia or iron deficiency who undergo surgical procedures have an increased risk for mortality and morbidity. Patient Blood Management programmes address this issue worldwide and try to improve patient outcomes through a complex set of measures targeting anaemia correction, minimisation of bleeding and improvement of anaemia tolerance, in all phases of perioperative care. The Patient Blood Management Initiative Group is a multidisciplinary team of physicians from specialties including anaesthesiology, nephrology, surgery, orthopaedics, haematology, gastroenterology and transfusion medicine.

Amyloid-β 11C-PiB-PET imaging results from 2 randomized bapineuzumab phase 3 AD trials.

Objective: To evaluate the effects of bapineuzumab on brain β-amyloid (Aβ) burden using (11)C-Pittsburgh compound B ((11)C-PiB)-PET.

Methods: Two phase 3 clinical trials, 1 each in apolipoprotein APOE ε4 carriers and noncarriers, were conducted in patients with mild to moderate Alzheimer disease dementia. Bapineuzumab, an anti-Aβ monoclonal antibody, or placebo, was administered by IV infusion every 13 weeks for 78 weeks.

[Postoperative pain management in elderly patient].

Pain is a common occurrence for the hospitalized elderly, and may often be under recognized and inadequately managed. Insufficient pain management can lead to the sequelae of emotional distress and depression, delirium, anxiety, sleep disturbances, and physical disabilities, as well as increased health care costs. Effective pain management of the older adult begins with pain assessment using the proper tools.
