Influence of different sources of vegetable, whey and microalgae proteins on the physicochemical properties and amino acid profile of fresh pork saus…
2019
Abstract The purpose of this study was to evaluate changes in the physicochemical properties and amino acid profiles of pork sausages prepared by including vegetable protein sources (beans, peas, and lentils), microalgae (Chlorella and Spirulina) or whey, as compared with a control (soy protein). Significant differences were found for all the studied parameters. The protein content was significantly lower in sausages made with pea protein compared with the control. Colour parameters changed significantly after the incorporation of microalgae proteins. Moreover, significant differences among treatments were observed in the amino acid profile. The inclusion of Spirulina proteins resulted in a…
Fruit production and quality evaluation of four litchi cultivars (Litchi chinensis Sonn.) grown in Mediterranean climate
2017
Introduction - The agronomic and qualitative responses of the litchi fruit (Litchi chinensis Sonn.) grown in Mediterranean climate are not yet studied. In this study, yield components, physico-chemical and sensory traits of four commercial litchi cultivars were recorded over two productive seasons. Materials and methods - Fruits of the cvs Tai So, Wai Chee, Brewster and Kwai Mai were collected at commercial maturity stage and subjected to productive (yield, efficiency, number of fruits, crop load), analytical (fruit weight, transversal diameter, longitudinal diameter, moisture, total soluble solid content (TSS), titratable acidity (TA), TSS/TA ratio, seed weight, peel weight, percentage of …
The impact of Carpobrotus cfr. acinaciformis (L.) L. Bolus on soil nutrients, microbial communities structure and native plant communities in Mediter…
2016
Background and aims: Carpobrotus spp. are amongst the most impactful and widespread plant invaders of Mediterranean habitats. Despite the negative ecological impacts on soil and vegetation that have been documented, information is still limited about the effect by Carpobrotus on soil microbial communities. We aimed to assess the changes in the floristic, soil and microbial parameters following the invasion by Carpobrotus cfr. acinaciformis within an insular Mediterranean ecosystem. Methods: Within three study areas a paired-site approach, comparing an invaded vs. a non-invaded plot, was established. Within each plot biodiversity indexes, C and N soil content, pH and microbial biomass and st…
Culture into perfusion-assisted bioreactor promotes valve-like tissue maturation of recellularized pericardial membrane
2020
Derivation of tissue-engineered valve replacements is a strategy to overcome the limitations of the current valve prostheses, mechanical, or biological. In an effort to set living pericardial material for aortic valve reconstruction, we have previously assessed the efficiency of a recellularization strategy based on a perfusion system enabling mass transport and homogenous distribution of aortic valve-derived “interstitial” cells inside decellularized pericardial material. In the present report, we show that alternate perfusion promoted a rapid growth of valve cells inside the pericardial material and the activity of a proliferation-supporting pathway, likely controlled by the YAP transcrip…
Mapping landscape canopy nitrogen content from space using PRISMA data
2021
Abstract Satellite imaging spectroscopy for terrestrial applications is reaching maturity with recently launched and upcoming science-driven missions, e.g. PRecursore IperSpettrale della Missione Applicativa (PRISMA) and Environmental Mapping and Analysis Program (EnMAP), respectively. Moreover, the high-priority mission candidate Copernicus Hyperspectral Imaging Mission for the Environment (CHIME) is expected to globally provide routine hyperspectral observations to support new and enhanced services for, among others, sustainable agricultural and biodiversity management. Thanks to the provision of contiguous visible-to-shortwave infrared spectral data, hyperspectral missions open enhanced …
Correlation of the chemiluminescence-activity of peripheral blood monocytes with CSF parameters of inflammation and the clinical course of patients w…
2009
– The chemiluminescence-activity (CL-A) of peripheral blood monocytes (MO) was measured in eight patients with lymphocytic meningitis or meningoencephalitis and compared to CSF parameters and the clinical course. The initial maximum CL-A was around four times above the control and decreased to normal values within approximately 20 days. Poor correlations were found when the CL-A was compared to CSF parameters in the total group of patients. With regard to the CSF parameters in individual patients the CL-A was closely related to the cell count, to a lesser degree to the protein content, but not to the IgG content. Finally, a very good correlation of the CL-A was found with the clinical cours…
Diet high in protein-rich foods with structured sport activity may be useless to lose fat mass and maintain fat-free mass
2020
Background The aim of this study was to demonstrate that a normal protein diet along with minimal sports activity can be enough to lose fat mass and maintain muscle mass. Methods All participants were prescribed a hypocaloric nutritionally balanced Mediterranean-style diet tailored to the individual for 8 weeks. Body composition and energy expenditure were measured. Sedentary patients (G1) were only recommended to perform minimal aerobic training, while sport subjects (G2) were prescribed structured physical activity and higher calorie and protein contents in the diet. Results There were no significant differences between the two groups for any of the measured parameters. Conclusions The mo…
Hyperechogenicity of the substantia nigra in healthy controls is related to MRI changes and to neuronal loss as determined by F-Dopa PET
2009
Abstract Transcranial ultrasound (TCS) has been shown to reveal hyperechogenicity of the substantia nigra (SN) in Parkinsonian patients and in about 10% of healthy controls. It is hypothesized that SN hyperechogenicity in healthy subjects is a vulnerability marker for idiopathic Parkinson's disease (IPD). Although there is strong evidence that the echomarker results from increased local iron content, the exact pathophysiological mechanisms remain incompletely understood. Thus, prognostic impact can only be estimated. We examined 14 subjects with SN hyperechogenicity (SN+) (7 IPD patients and 7 controls) and 7 healthy controls without the echomarker (SN−) by a magnetic resonance imaging meth…
Elevated Protein Content and Prolyl 4-Hydroxylase Activity in Severely Degenerated Human Annulus Fibrosus
2000
Alterations involved with the intervertebral disc degeneration are partly well described, however, it is not so well known how collagen network is affected by the disease. We analyzed the rate of collagen biosynthesis (estimated by the enzymic activities of prolyl 4-hydroxylase and galactosylhydroxylysyl glucosyltransferase) and the level of hydroxylysylpyridinoline and lysylpyridinoline crosslinks both in normal (n=7) and degenerated (n=7) human annulus fibrosus. The activity of prolyl 4-hydroxylase was significantly increased in degenerated tissue. However, no significant changes in the collagen content or in the amount of hydroxylysylpyridinoline and lysylpyridinoline collagen crosslinks…
Mößbauer- und ESCA-Untersuchungen zur Bildung oxidischer Eisenphasen in wäßrigen Medien unter der Einwirkung organischer Korrosionsinhibitoren
1982
Korrosionsschichten auf Stahl nach Exposition in Wasser mit bestimmter Harte und Chloridgehalt wurden hinsichtlich der Wirksamkeit beigefugter organischer Inhibitoren mittels Mosbauer- und ESCA-Spektroskopie untersucht. Es entstehen relativ dicke Schichten mit einem unerwartet niedrigen Eisengehalt in Form von FeOOH. Die Schichten enthalten merkliche Mengen von Ionen aus der Testlosung und auch Abbauprodukte der Inhibitormolekule. Letztere werden anscheinend in dem korrosiven Medium zersetzt. Es ist anzunehmen, das das Gesamtmolekul zwar den Transport des Inhibitors zum Metall beeinflust, die eigentliche Inhibierung aber allein durch funktionelle Gruppen erfolgt. Mossbauer and ESCA investig…
