An Uncommon Presentation of Aortic Endarteritis.

Endocarditis is an uncommon infectious complication of congenital heart disease (CHD), typically presenting with fever as its primary symptom; however, its occurrence may not always be accompanied by fever. This paper elaborates on a case involving a patient with surgically corrected Berry syndrome and residual aortic coarctation. The clinical presentation of aortic endarteritis in this case manifested as seizures attributed to a hemorrhagic stroke.

Design and Characterization of a Cheese Spread Incorporating Extract.

Marine algae have been emerging as natural sources of bioactive compounds, such as soluble dietary fibers and peptides, presenting special interest as ingredients for functional foods. This study developed a cheese spread incorporating red seaweed extract and subsequently characterized it in terms of nutritional, pH, and microbiological parameters and bioactivities including prebiotic, antidiabetic, antihypertensive, and antioxidant activities. This food was produced through incorporation of extract (3%), obtained via enzymatic extraction Viscozyme L in a matrix containing whey cheese (75%) and Greek-type yoghurt (22%).

Simultaneous transcatheter pulmonary and tricuspid valve-in-ring implantation.

We report on a 50-year-old female patient, with several severe comorbidities and high-surgical risk, in whom we successfully performed a simultaneous transcatheter pulmonary and tricuspid valve-in-ring implantation to treat both bioprosthetic pulmonary valve dysfunction and native torrential tricuspid valve regurgitation, the latter previously managed with a Carpentier annuloplasty ring.

and Enzymatic Extracts: Chemical, Structural, and Cytotoxic Characterization.

Seaweeds, which have been widely used for human consumption, are considered a potential source of biological compounds, where enzyme-assisted extraction can be an efficient method to obtain multifunctional extracts. Chemical characterization of and extracts obtained by Alcalase and Viscozyme assisted extraction, respectively, showed an increment of macro/micro elements in comparison to the corresponding dry seaweeds, while the ratio of Na/K decreased in both extracts. Galactose, mannose, xylose, fucose, and glucuronic acid were the main monosaccharides (3.

Abdominal pain of cardiovascular origin.

Infective endocarditis is a microbial infection of the endocardium and it is rare in the pediatric population. In children, congenital heart disease is one of the most important risk factors for developing infective endocarditis and can involve other structures in addition to cardiac valves. The prognosis is generally better than in other forms of endocarditis, although the average mortality rate in the pediatric population is 15-25%.

Chemical and structural characterization of Pholiota nameko extracts with biological properties.

Edible mushrooms including Pholiota nameko are excellent sources of extractable bioactive compounds with much to explore. Enzymatic extractions with Cellulase and Viscozyme were responsible for highest extraction yields (67-77%). No strong antioxidant activity was observed although extracts were able to scavenge ABTS(+) and OH(+).

Chemical composition of red, brown and green macroalgae from Buarcos bay in Central West Coast of Portugal.

Six representative edible seaweeds from the Central West Portuguese Coast, including the less studied Osmundea pinnatifida, were harvested from Buarcos bay, Portugal and their chemical characterization determined. Protein content, total sugar and fat contents ranged between 14.4% and 23.

Impact of enzyme- and ultrasound-assisted extraction methods on biological properties of red, brown, and green seaweeds from the central west coast of Portugal.

Seaweeds are an excellent source of bioactive compounds, and therefore the use of sustainable and food compatible extraction methods such as enzyme-assisted (EAE) and ultrasound-assisted extraction were applied on Sargassum muticum, Osmundea pinnatifida, and Codium tomentosum. Extracts were evaluated for proximate characterization and biological properties. Higher extraction yields were observed for C.

The impact of uranium mine contamination of soils on plant litter decomposition.

As part of a tier 3 risk assessment performed for a uranium mining area, the ability of soils with different degrees of metal contamination to degrade organic matter was assessed using litter bags filled with leaves of Quercus robur, Pinus pinaster, Salix atrocinerea, or a mixture of the three species. Litter bags were exposed at different sites within the mine area and at a reference area for 3, 6, 9, and 12 months. Biomass loss, nitrogen (N), phosphorus (P), carbon (C) and total fatty acid, total phenolic, and ergosterol contents were assessed for each litter bag retrieved from the field.

Strategies based on silica monoliths for removing pollutants from wastewater effluents: a review.

Silica monoliths have been used for more than half a century in a wide variety of applications, such as stationary phases for microextraction fibers, capillary columns for chromatography, in the encapsulation of biomolecules for affinity chromatography and for microfluidic or microarray chips and, more recently, and less well known for wastewater treatment. The main objective of this review article is to specifically overview the strategies that use silica monoliths for the removal of chemical pollutants from wastewater effluents or prepared solutions. The discussion of advantages and drawbacks of such strategies will be supported with the main studies carried out so far which have been performed in laboratory environment only.

Development of probiotic tablets using microparticles: viability studies and stability studies.

Alternative vectors to deliver viable cells of probiotics, to those conferring limited resistance to gastrointestinal conditions, still need to be sought. Therefore the main goal of the study was to develop tablets able to protect entrapped probiotic bacteria from gastric acidity, thus providing an easily manufacturing scale-up dosage form to deliver probiotics to the vicinity of the human colon. Whey protein concentrate microparticles with Lactobacillus paracasei L26 were produced by spray-drying and incorporated in tablets with cellulose acetate phthalate and sodium croscarmellose.

Marine biotechnology advances towards applications in new functional foods.

This review summarizes the advances in biotechnological tools for production of functional ingredients, including enzymes, for the food industry.

[Emery-Dreifuss muscular dystrophy: case report].

Emery-Dreifuss muscular dystrophy type 1 (EDMD1) is a familial disease with X-Linked recessive transmission, caused by a mutation in a nuclear envelope protein, emerin. Clinical manifestations usually occur in adolescence and include contractures, muscle atrophy and weakness, and cardiac conduction disturbances. We describe the case of a young male, aged 16, with first-degree atrioventricular (AV) block and limited extension of both forearms.

Metabolic profiling of potential probiotic or synbiotic cheeses by nuclear magnetic resonance (NMR) spectroscopy.

To assess ripening of potential probiotic cheeses (containing either Lactobacillus casei -01 or Bifidobacterium lactis B94) or synbiotic cheeses with fructooligosaccharides (FOS) or a 50:50 mix of FOS/inulin, metabolic profiles have been obtained via classical biochemical analyses and by NMR spectroscopy. The addition of prebiotics to the cheeses resulted in lower proteolysis indices, especially in those synbiotic cheeses inoculated with B. lactis B94.

Evaluation of tertiary treatment by fungi, enzymatic and photo-Fenton oxidation on the removal of phenols from a kraft pulp mill effluent: a comparative study.

Pulp and paper mills generate pollutants associated to their effluents depending upon the type of process, type of the wood materials, process technology applied, management practices, internal recirculation of the effluent for recovery, the amount of water used in the industrial process and type of secondary treatment. This study is the first that reports a simultaneous evaluation of the effects of tertiary treatments by fungi (Rhizopus oryzae and Pleurotus sajor caju), by enzyme (laccase) and by an oxidation process (photo-Fenton) on individual phenols (vanillin, guaiacol, phloroglucinol, vanillic acid and syringic acid) of a Eucalyptus globulus bleached kraft pulp and paper mill final effluent after secondary treatment (BKPME). The tertiary treatments were applied on BKPME samples and in BKPME samples supplemented with extra concentration of each phenol.

High blood pressure in the pediatric age group.

The definition of hypertension (HT) in the pediatric age group is based on the normal distribution of blood pressure (BP) in healthy children. Normal BP is defined as being below the 90th percentile for gender, age and height, and hypertension as equal to or higher than the 95th percentile on at least three separate occasions. If the values are above the 90th percentile but below the 95th percentile, the child should be considered prehypertensive.

Transcatheter closure of a fenestration in intracardiac Fontan circulation.

We present a case of tricuspid atresia and the treatment that was used in a child now aged 12. The malformation was corrected at the age of five through intracardiac Fontan circulation. Later, the child developed a right-to-left shunt due to dehiscence in the intra-atrial conduit, causing significant desaturation.
