BACKGROUND: Influenza burden in Brazil is considerable with 4.2-6.4 million cases in 2008 and influenza-like-illness responsible for 16.9% of hospitalizations. Cost-effectiveness of influenza vaccination may be assessed by different types of models, with limitations due to data availability, assumptions, and modelling approach. OBJECTIVE: To understand the impact of model complexity, the cost-utility of quadrivalent versus trivalent influenza vaccines (QIV versus TIV) in Brazil was estimated using three distinct models: a 1-year decision tree population model with three age groups (FLOU); a more detailed 1-year population model with five age groups (FLORA); and a more complex lifetime multi-cohort Markov model with nine age groups (FLORENCE)...

Antibiotic-caused changes in intestinal flora (dysbiosis) can have various effects on the host. Secondary bile acids produced by intestinal bacteria are ligands for specific nuclear receptors, which regulate glucose, lipid, and drug metabolism in the liver. The present study aimed to clarify the effect of changes in secondary bile acids caused by antibiotic-induced dysbiosis on the host physiology, especially glucose, lipid, and drug metabolism. After oral administration of non-absorbable antibiotics for 5 days, decreased amounts of secondary bile acid-producing bacteria in faeces and a reduction in secondary bile acid [lithocholic acid (LCA) and deoxycholic acid (DCA)] levels in the liver were observed...

The use of glyphosate, as a post-emergence broad-spectrum herbicide in genetically modified glyphosate-tolerant (GT) cotton, supposes a big change in weed management programs with respect to a conventional regime. Thus, alterations in arable flora and arthropod fauna must be considered when evaluating their potential impacts. A 3-year farm-scale study was conducted in a 2-ha GT cotton crop, in southern Spain, to compare the effects of conventional and glyphosate herbicide regimes on weed abundance and diversity and their consequences for ground-dwelling predators...

Diatoms are a diverse and ecologically important group of phytoplankton. Although most species are considered free living, several are known to interact with other organisms within the plankton. Detailed imaging and molecular characterization of any such partnership is, however, limited, and an appraisal of the large-scale distribution and ecology of such consortia was never attempted. Here, observation of Tara Oceans samples from the Benguela Current led to the detection of an epibiotic association between a pennate diatom and a tintinnid ciliate...

Background -Anthracyclines, such as doxorubicin (DOX), are potent anti-cancer agents for the treatment of solid tumors and hematological malignancies. However, their clinical use is hampered by cardiotoxicity. This study sought to investigate the role of PI3Kγ in DOX-induced cardiotoxicity and the potential cardio-protective and anti-cancer effects of PI3Kγ inhibition. Methods -Mice expressing a kinase-inactive PI3Kγ or receiving PI3Kγ selective inhibitors were subjected to chronic DOX treatment. Cardiac function was analyzed by echocardiography and DOX-mediated signaling was assessed in whole hearts or in isolated cardiomyocytes...

Telfairia occidentalis possesses high antioxidant activity. However, the antioxidant components of the plant have not yet been identified. This study was undertaken to identify the phenolics in the leaf of the plant. Extract and fractions of the leaf of the plant were analysed using the HPLC and GCMS. HPLC analysis revealed the presence of gallic acid (22.19μg/mg), catechin (29.17μg/mg), caffeic acid (9.17μg/mg), ferulic acid (0.94μg/mg), sinapic acid (1.91 μg/mg) and 4-hydroxy benzoic acid (43.86 μg/mg) in the aqueous extract...

BACKGROUND: Fragile X syndrome (FXS) is the most common form of inherited intellectual disability. FXS is caused by a silencing of the FMR1 gene that results in a loss or absence of the gene's protein product, fragile X mental retardation protein. The phenotype of FXS is consistently associated with heightened anxiety, although no previous study has investigated attentional bias toward threat, a hallmark of anxiety disorders, in individuals with FXS. METHODS: The current study employed a passive-viewing eye-tracking version of the dot probe task to investigate attentional biases toward emotional faces in young children with FXS (n = 47) and without FXS (n = 94)...

Laser-capture microdissection (LCM) allows for retrieval of specific cell populations in situ. By combining immunofluorescent labeling with LCM, mRNAs can be probed by qRT-PCR for determining in situ gene expression during health and disease. This approach permits obtaining and analyzing histologically enriched cell populations in a tissue that can be hardly obtained from other methods such as white matter astrocytes from rodents or any individual cell population from archival human or rodent brain tissues...

A 52-year-old man developed interstitial pneumonitis during treatment with desvenlafaxine for major depressive disorder. The man received desvenlafaxine at 50 mg for symptoms of depression 4 years earlier. Six months after a dose increase to 100 mg, he developed bronchitic symptoms with mild, persistent dyspnea. Investigations revealed a restrictive pattern on pulmonary function testing, bilateral upper lobe reticular opacities with traction bronchiectasis on radiology imaging, and end-stage interstitial fibrosis with honeycomb changes consistent with chronic hypersensitivity pneumonitis on open lung biopsy...

BACKGROUND: Nanoparticles (NPs) administered orally will meet the gut microbiota, but their impacts on microbiota homeostasis and the consequent physiological relevance remain largely unknown. Here, we describe the modulatory effects and the consequent pharmacological outputs of two orally administered fullerenols NPs (Fol1 C60(OH)7(O)8 and Fol113 C60(OH)11(O)6) on gut microbiota. RESULTS: Administration of Fol1 and Fol113 NPs for 4 weeks largely shifted the overall structure of gut microbiota in mice...

Fermented milk products are rising in popularity throughout the world because of their health benefits, including improving digestion, normalizing the function of the immune system, and aiding in weight management. This study applies an in situ quantitative NMR method to monitor chemical changes in three kinds of fermented milk products, Bulgarian yogurt, Caspian Sea yogurt and kefir, during fermentation. As a result, the concentration changes in nine organic compounds, α/β-lactose, α/β-galactose, lactic acid, citrate, ethanol, lecithin, and creatine, were monitored in real time...

BACKGROUND: Rhodococcus equi is an important cause of foal pneumonia. While its isolation from different sources has been widely evaluated, there is a need to better understand the R. equi epidemiology from samples of the nasal cavity of healthy horses.

Microbiome studies show altered microbiota in head and neck squamous cell carcinoma (HNSCC), both in terms of taxonomic composition and metabolic capacity. These studies utilized a traditional bioinformatics methodology, which allows for accurate taxonomic assignment down to the genus level, but cannot accurately resolve species level membership. We applied Resphera Insight, a high-resolution methodology for 16S rRNA taxonomic assignment that is able to provide species-level context in its assignments of 16S rRNA next generation sequencing (NGS) data...

Caspase-4/5 in humans and caspase-11 in mice bind hexa-acylated lipid A, the lipid moeity of lipopolysaccharide (LPS), to induce the activation of non-canonical inflammasome. Pathogens such as Francisella novicida express an under-acylated lipid A and escape caspase-11 recognition in mice. Here, we show that caspase-4 drives inflammasome responses to F. novicida infection in human macrophages. Caspase-4 triggers F. novicida-mediated, gasdermin D-dependent pyroptosis and activates the NLRP3 inflammasome. Inflammasome activation could be recapitulated by transfection of under-acylated LPS from different bacterial species or synthetic tetra-acylated lipid A into cytosol of human macrophage...

Macrophages populate the healthy myocardium and, depending on their phenotype, may contribute to tissue homeostasis or disease. Their origin and role in diastolic dysfunction, a hallmark of cardiac aging and heart failure with preserved ejection fraction, remain unclear. Here we show that cardiac macrophages expand in humans and mice with diastolic dysfunction, which in mice was induced by either hypertension or advanced age. A higher murine myocardial macrophage density results from monocyte recruitment and increased hematopoiesis in bone marrow and spleen...
