Dyslipidemia is associated with increased risk of cardiovascular disease and atherosclerosis, and hence with high morbidity and mortality. This study investigated the effects of the nitroxide 4-hydroxy-2,2,6,6-tetramethylpiperidine 1-oxyl (Tempol) on lipid profile and cardiac morphology in low-density lipoprotein (LDL) receptor gene knockout (LDLr-/-) mice.Male LDLr-/- mice (three months old, approximately 22 g weight) were divided into the following groups: controls, including (1) standard chow (SC, ...

People's concern with the health of their animals has grown as the concern with their own health. The phenomenon known as humanization of animals has contributed to the emergence of this awareness about the care that animal owners need to have in relation with food, thus creating a new market nourishment, of natural and healthy foods. With revenues of US$ 91 billion in 2018, the pet food market is seen as a valuable market with great growth prospects for years to come. Nutrition is one of the most ...

Abstract We studied the chemical structure and yield of low-molecular-mass carbohydrates (LMMC) and soluble polysaccharides produced by green and red morphs of Gracilaria domingensis . Red plants had higher amounts of the LMMC floridoside than green morphs (324.4±8.1 and 220.1±6.0 μmol g -1 dry biomass, respectively). The yield of polysaccharides was similar between morphs (46.3±5.8% for the red and 41.4±8.3% for the green) as was the monosaccharide composition. The same agaran (6- O -methylated and sulphated) ...

BACKGROUND: Leishmaniasis is one of the most important infectious diseases worldwide. Our study can provide more knowledge about angiogenic and hypoxic events in leishmaniasis. We attempted to verify whether the HIF-1 α protein expression may be associated to VEGF-A, VEGFR2 and MMP9 in leishmanial lesions. OBJECTIVES: Besides understanding the pathway, we performed the correlation of VEGF-A, VEGFR2 and MMP9 proteins. METHODS: In this study, we gathered 54 paraffin blocks taken from skin lesions ...

A homogeneous iota/nu-hybrid carrageenan (71% iota- and 21% nu-) isolated from Eucheuma denticulatum was used as a model compound to study the cyclization reaction of α-d-galactose 2,6-disulfate units to 3,6-anhydro-α-d-galactose 2-sulfate. The rate of cyclization, at 70 °C, of this carrageenan is about 50 times faster than that of a porphyran (non-sulfated β-d-galactose linked to α-l-galactose 6-sulfate) and 210 times faster when compared with a lambda-carrageenan (2-sulfated β-d-units linked to α- ...

The rate of alkaline cyclization of porphyran is in the same order as those of carrageenan model compounds containing non-sulfated β-d-galactose units, showing that the cyclization of the α-galactosyl units does not depend on the β-d-adjacent sugar residues when they carry no sulfate groups. It also suggests that there is no influence of the α-d-galactose 2-sulfate on the cyclization rate, in spite of its change from the equatorial to the axial position during the conversion of the 4C1 to 1C4 chair ...

Summary The aim of this work was to present the clinical and embryological outcomes of 65 azoospermic patients with non‐mosaic K linefelter syndrome ( KS ), treated by testicular sperm extraction ( TESE ), followed by intracytoplasmic sperm injection ( ICSI ), either with fresh or cryopreserved testicular spermatozoa. In total, spermatozoa were recovered in 25/65 (38.5%) of the cases. Of the 48 patients who choose to perform TESE followed by ICSI using fresh testicular spermatozoa (treatment TESE ), spermatozoa was ...

Within the context of the ongoing sporotrichosis epidemic in the State of Rio de Janeiro, Brazil, sick cats plays an important role in the zoonotic transmission. The aim of this study was to update the number of feline cases diagnosed at the Fundação Oswaldo Cruz (2005-2011).The medical records of the cats followed were reviewed; the inclusion criterion was the isolation of Sporothrix spp. in culture.In total, 2,301 feline cases were ...

Summary Leishmaniasis covers a broad spectrum of diseases with distinct, and sometimes overlapping, characteristics. The common thread in all forms of leishmaniasis is the infection by the parasite Leishmania belonging to the genus Leishmania . Upon infection of humans, there can be at least three outcomes, (i) control of Leishmania by the host immune response resulting in asymptomatic disease, (ii) patent infection and development of a relatively mild form of leishmaniasis and (iii) patent infection ...

Chronic dental periapical lesions result from chronic inflammation of periapical tissues caused by continuous antigenic stimulation from infected root canals. Recent findings have suggested that T helper (Th) 1 and Th2-like cytokines are important in the pathogenesis of chronic periapical inflammatory diseases. However, the mechanisms regulating these immunoinflammatory pathways have not been fully elucidated. Thus, the aim of this study was to evaluate interleukin (IL)-4, IL-12, and interferon γ ( ...

Background Trypanosoma cruzi strains are currently classified into six discrete typing units (DTUs) named TcI to VI. It is known that these DTUs have different geographical distribution, as well as biological features. TcI and TcII are major DTUs found in patients from northern and southern Latin America, respectively. Our hypothesis is that upon infection of human peripheral blood cells, Y strain (Tc II) and Col cl1.7 (Tc I), cause distinct immunological changes, which might influence the clinical ...

Sporotrichosis occurs worldwide, and the metropolitan region of Rio de Janeiro, Brazil, is a main endemic area, with a large number of human and animal cases in the last 19 years. This mycosis is more frequently described in cats rather than in dogs. There are a limited number of oral antifungal agents for the treatment of sporotrichosis in animals. In this context, the effectiveness of terbinafine in the treatment of sporotrichosis in humans, as well as the promising results of in vitro susceptibility ...

The application of carbon paste electrodes modified with porphyran-capped gold nanoparticles (CPE/AuNps-PFR) to detect an important anticancer drug, 5-fluorouracil (5-FU), is described. Gold nanoparticles (AuNps) were synthesized through a green one-pot route, by using porphyran (PFR) (a sulfated polysaccharide extracted from red seaweed) as reducing and stabilizing agent. The reaction temperature and the concentrations of AuCl4− and PFR for AuNps-PFR synthesis were optimized by using a 23 full factorial ...

Corynebacterium diphtheriae is typically recognized as the a etiological agent of diphtheria, a toxaemic infection of the respiratory tract; however, both non-toxigenic and toxigenic strains are increasingly isolated from cases of invasive infections. The molecular mechanisms responsible for bacterial colonization and dissemination to host tissues remain only partially understood. In this report, we investigated the role of DIP2093, described as a putative adhesin of the serine-aspartate repeat ( ...

Here, we asked whether in vitro infection of human monocytes by Leishmania strains responsible for distinct clinical manifestations leads to early changes in immunological characteristics and ability of the host cells to control Leishmania. We evaluated the expression of toll- ...

Chagas disease is caused by the hemoflagellate protozoa Trypanosoma cruzi and is one of the most important neglected tropical diseases, especially in Latin American countries, where there is an association between low-income populations and mortality.

The Kato-Katz (KK) technique is the mainstay mapping tool for the diagnosis of Schistosoma mansoni infection, despite showing poor sensitivity in cases of low-intensity infections. As an alternative, a rapid point-of-care circulating cathodic antigen diagnostic test (POC-CCA) has been commercially developed that involves a simple urine assay to detect S. mansoni, rather than a stool-based parasitological examination. Although POC-CCA has proven to be a more sensitive test than KK, it is not yet clear ...

Visceral leishmaniasis (VL) or kala-azar, the most severe form of leishmaniasis, can lead to death if not properly diagnosed and treated. Correct identification of infected patients and reservoirs is vital for controlling the spread of leishmaniasis. Current diagnostic kits for leishmaniasis show high sensitivity and specificity, but can also result in false negatives and cross reactions with related parasitic infections. New diagnostic methods with greater accuracy are urgently needed for diagnosis ...
