Few studies explore how diarrhoeal mortality varies subnationally, especially by cause, which is important for targeting investments. Even fewer examine indirect effects of diarrhoeal morbidity on child mortality. We estimated the subnational d...

Authors: Christensen LFB, Schafer N, Wolf-Perez A, Madsen DJ, Otzen DE Abstract Functional amyloid (FuBA) is produced by a large fraction of all bacterial species and represents a constructive use of the stable amyloid fold, in contrast to the pathological amyloid seen in neurodegenerative diseases. When assembled into amyloid, FuBA is unusually robust and withstands most chemicals including denaturants and SDS. Uses include strengthening of bacterial biofilms, cell-to-cell communication, cell wall construction and even bacterial warfare. Biogenesis is under tight spatio-temporal control, thanks to a simple but eff...

Abdel-Fattah, Assunta BorzacchielloAbstractInjectable hydrogels have revealed the great potential for use as scaffolds in cartilage and bone tissue engineering. Here, thermosensitive and injectable hydrogels containing β-tricalcium phosphate, hyaluronic acid, and corn silk extract-nanosilver (CSE-Ag NPs) were synthesized for their potential use in bone tissue regeneration applications. Spherical nanoparticles of silver were biosynthesized through microwave-ass...

Here, we demonstrate a novel technique to induce the antibacterial response in biomaterial substrates via surface polarization. In the present work, hydroxyapatite, HA-xZnO (x = 3.0, 4.5 and 7.5 wt. %) composites were processed by solid state sintering route at 1250 °C for 2 h. After phase evolution analyses, the detailed dielectric and electrical measurements were perf...

Abstract Retrospective analysis has already shown correlation between severe Chronic Periodontitis (CP) cases with human papiloma virus (HPV). Hence, we aimed to explore deep-seated infected granulation tissue removed during periodontal flap surgery procedures for residential bacterial species between HPV+ and HVP- CP cases, which may serve as good predisposition marker for oral cancer. All CP-granulation samples showed the prominence of Firmicutes, Proteobacteria, and Bacteroidetes phyla with an abundance of gram negative anaerobes, except Streptococcus. In Beta diversity nonmetric multidimensional scaling plot, ...

In this study, the protective effects of short-chain fructo-oligosaccharides (scFOS) on oxidized oil feeding-induced intestinal dysfunction were evaluated. Piglets were fed either a control diet, an oxidized oil diet, or an oxidized oil diet supplemented with scFOS (4 g/kg diet) for 28 days. The results showed that scFOS increased the expression of tight junction proteins and decreased the production of malondialdehyde and pro-inflammatory cytokines in jejunum of oxidized oil-challenged piglets. In addition, scFOS mitigated oxidized oil-dependent changes in the relative abundances of Prevotella_9, Bacteroides, Campylob...

In this study, we analyzed and compared the intestinal microbiota composition of patients with idiopathic focal epilepsy (n = 30) and healthy volunteer group (n = 10) by 16s ribosomal DNA sequencing. Proteobacteria phylum was found to be higher in patients with epilepsy (25.4%) than in healthy volunteers group (1.5%). The genera of Campylobacter, Delftia, Haemophilus, Lautropia, Neisseria among Proteobacteria phylum were found to be statistically significantly higher in patients with epilepsy than in healthy volunteers (p
