Obesity is an important modifiable risk factor for chronic diseases. While there is increasing focus on the role of dietary sugars, there remains a paucity of data establishing the association between sugar intake and obesity in the general public. The objective of this study was to investigate associations of estimated sugar intake with odds for obesity in a representative sample of English adults. We used data from 434 participants of the 2005 Health Survey of England. Biomarkers for total sugar intake were measured in 24 h urine samples and used to estimate intake...

The innate immune response is critical for animal homeostasis and is conserved from invertebrates to vertebrates. This response depends on specialized cells that recognize, internalize, and destroy microbial invaders through phagocytosis. This is coupled to autonomous or non-autonomous cellular signaling via reactive oxygen species (ROS) and cytokine production. Lipids are known signaling factors in this process, as the acute phase response of macrophages is accompanied by systemic lipid changes that help resolve inflammation...

Adenosine triphosphate (ATP) accumulates at sites of tissue injury and inflammation. Effects of extracellular ATP are mediated by plasma membrane receptors named P2 receptors (P2Rs). The P2R most involved in inflammation and immunity is the P2X7 receptor (P2X7R), expressed by virtually all cells of innate and adaptive immunity. P2X7R mediates NLRP3 inflammasome activation, cytokine and chemokine release, T lymphocyte survival and differentiation, transcription factor activation, and cell death. Ten human P2RX7 gene splice variants and several SNPs that produce complex haplotypes are known...

In many biotechnological applications, it is useful for gene expression to be regulated by multiple signals, as this allows the programming of complex behaviour. Here we implement, in Escherichia coli, a system that compares the concentration of two signal molecules, and tunes GFP expression proportionally to their relative abundance. The computation is performed via molecular titration between an orthogonal σ factor and its cognate anti-σ factor. We use mathematical modelling and experiments to show that the computation system is predictable and able to adapt GFP expression dynamically to a wide range of combinations of the two signals, and our model qualitatively captures most of these behaviours...

Glucocorticoids (GCs) are widely employed in inflammatory, autoimmune and neoplastic diseases, and, despite the introduction of novel therapies, remain the first-line treatment for inducing remission in inflammatory bowel disease (IBD). Given the high incidence of suboptimal response, associated with a significant number of side effects, that are particularly severe in paediatric patients, the identification of subjects that are most likely to respond poorly to GCs is extremely important. Recent evidence suggests that the long non-coding RNA (lncRNA) GAS5 could be a potential marker of GC resistance...

Previous studies have examined the association between elevated serum uric acid (SUA) level and hypertension; however, the association in the Chinese elderly is still uncertain. A cross-sectional study was performed in a rural district of Beijing. A total of 2,397 participants (967 men and 1,430 women) completed the survey. The SUA levels of participants were categorized into four levels using the quartiles (P25, P50, and P75) as cutoff values. Participant was diagnosed as hyperuricemia if the SUA level was ≥417 μmol/L (male) or ≥357 μmol/L (female)...

We demonstrate exceptionally large modulation of PL intensity in hierarchical titanium dioxide (TiO2) nanostructures exposed to molecular oxygen (O2). Optical responsivities up to about 1100% at 20% O2 concentrations are observed in hyperbranched anatase-phase hierarchical structures, outperforming those obtainable by commercial TiO2 nanopowders (up to a factor of ∼7 for response to synthetic air) and significantly improving the ones typically reported in PL-based opto-chemical gas sensing using MOXs. The improved PL response is discussed in terms of the specific morphology of hierarchical structures, characterized by simultaneous presence of small nanoparticles, large surface areas, and large voids...

A new concept for rapid and efficient salt removal from minute volumes of saline samples is presented by using multiple phase micro-electromembrane extraction (μ-EME). Disposable μ-EME unit is filled with five consecutive plugs of immiscible aqueous and organic solutions; the aqueous sample forms the central phase and is encompassed by two free liquid membranes (FLMs) and two extraction solutions. Salt cations and anions migrate in opposite directions from the sample solution on application of 300 V d.c. electric potential, cross the neighboring FLM and are transferred to the corresponding extraction solution...

Neuroblastoma (NB) is the most common extracranial pediatric solid tumor. Around 70% of patients with metastatic disease at diagnosis present bone-marrow infiltration, which is considered a marker of poor outcome; however, the mechanism underlying this specific tropism has to be elucidated. Tumor-derived exosomes may support metastatic progression in several tumors by interacting with the microenvironment, and may serve as tumor biomarkers. The main objective of this study was to identify an exosomal signature associated with NB metastatic bone-marrow dissemination...

Fungal species display an extraordinarily diverse range of lifestyles. Nevertheless, the survival of each species depends on its ability to sense and respond to changes in its natural environment. Environmental changes such as fluctuations in temperature, water balance or pH, or exposure to chemical insults such as reactive oxygen and nitrogen species exert stresses that perturb cellular homeostasis and cause molecular damage to the fungal cell. Consequently, fungi have evolved mechanisms to repair this damage, detoxify chemical insults, and restore cellular homeostasis...

Dumping syndromes are a frequent complication of gastric or bariatric surgery and include early and late dumping. Early dumping is a consequence of rapid delivery of hyperosmolar nutrients into the bowel. Late dumping is the result of a reactive hypoglycemia induced by a hyperinsulinemic response. These syndromes are becoming increasingly prevalent with the rising incidence of bariatric surgery. Effective management of these complications requires multidisciplinary collaboration. First line management of early and late dumping syndrome involves specific dietary and behavioral modifications which generally improve the quality of life of patients...
