Smart ulvan films responsive to stimuli of plasticizer and extraction condition in physico-chemical, optical, barrier and mechanical properties.

Smart films were produced with ulvan extracted from the green seaweed Ulva. lactuca at different extraction conditions, by varying the glycerol or sorbitol in specific plasticizer concentration. Chemical composition and molecular weight characteristics of ulvans were carried out by GLC and HPSEC analysis, respectively.

Anti-inflammatory and hemostatic effects of Desf.

The work presented here was aimed to investigate the anti-inflammatory and hemostatic activities of extract and to establish the relationship between its bioactivity and chemical composition. Twenty-three secondary metabolites were identified, most of them are good anti-inflammatory agents, in line with data by carrageenin-induced rat paw edema assays of the -butanol extract showing high anti-inflammatory inhibition (63.90%) of edema swelling in the rat paw at the dose 200 mg/kg after 4 h.

Effect of pH on the functional properties of Arthrospira (Spirulina) platensis protein isolate.

In the present study, a protein isolate extracted from Arthrospira platensis by isoelectric precipitation was evaluated for its functional properties. The maximum nitrogen solubility was 59.6±0.

Whole-body (201)Tl scintigraphy can detect exercise lower limb perfusion abnormalities in asymptomatic diabetic patients with normal Doppler pressure indices.

Significant lower limb arterial obstruction is usually detected by Doppler ankle-brachial pressure index (ABPI) measurement. However, ABPI is non-contributory in cases of diabetic medial sclerosis or calcifications and is unsuitable for the detection of small vessel involvement. Thallium-201, a perfusion agent, is frequently used for the investigation of coronary artery disease, and whole-body (201)Tl scintigraphy (WBS) has also been reported to be useful in the assessment of peripheral artery disease (PAD).

Prognostic value of radionuclide angiography in patients with right ventricular arrhythmias.

Background: The prognosis of patients with right ventricular (RV) arrhythmias remains uncertain. This study prospectively evaluated the prognostic value of RV and left ventricular (LV) involvement assessed by radionuclide angiography (RNA) as predictors for sudden death.

Methods And Results: Patients (n=188) with severe arrhythmias originating from the RV were followed up for a mean of 45+/-34 months.
