Trends in overweight and obesity over 22 years in a large adult population: the HUNT Study, Norway

Some reports indicate that the obesity epidemic may be slowing down or halting. We followed body mass index (BMI) and waist circumference (WC) in a large adult population in Norway (n = 90 000) from 1984–1986 (HUNT1) through 1995–1997 (HUNT2) to 2006–2008 (HUNT3) to study whether this is occurring in Norway. Height and weight were measured with standardized and identical methods in all three surveys; WC was also measured in HUNT2 and HUNT3. In the three surveys, mean BMI increased from 25.3 to 26.5 and 27.5 kg m−2 in men and from 25.1 to 26.2 and 26.9 kg m−2 in women. Increase in prevalence of obesity (BMI ≥ 30 kg m−2) was greater in men (from 7.7 to 14.4 and 22.1%) compared with women (from 13.3 to 18.3 and 23.1%). In contrast, women had a greater increase in abdominal obesity (WC ≥ 102 cm for men and WC ≥ 88 cm for women). There was a continuous shift in the distribution curve of BMI and WC to the right, demonstrating that the increase in body weight was occurring in all weight groups, but the increase of obesity was greatest in the youngest age groups. Our data showed no signs of a halt in the increase of obesity in this representative Norwegian population.
Vesselplasty: a new technical approach to treat symptomatic vertebral compression fractures.

OBJECTIVE The objective of our study was to evaluate the effectiveness and safety of vesselplasty to treat symptomatic vertebral compression fractures (VCFs). SUBJECTS AND METHODS Twenty-nine patients undergoing vesselplasty at our institution between April 2006 and February 2008 were enrolled in the study. All patients had been undergoing medical therapy for one or more painful VCFs. Pain, mobility, and analgesic use scores were obtained, and restoration of vertebral body height was evaluated. A two-tailed paired Student's t test was used to compare differences in the mean scores for levels of pain, mobility, and analgesic use before and after the procedure and to evaluate changes in vertebral body height. We analyzed the influence of the age of the fracture and its cause in the variations in the pain, mobility, and analgesic use scores. RESULTS Seven of the 29 patients had fractures in more than one level, for a total of 37 procedures. The cause of the vertebral collapse was osteoporosis in 27 (73%), high-impact trauma in five (13.5%), myeloma in three (8%), and metastatic fracture in two (5.4%). The average pain score before treatment was 8.72 +/- 1.25 (SD), whereas the average pain score after treatment was 3.38 +/- 2.35. The average mobility score before treatment was 2.31 +/- 1.94, whereas the average mobility score after treatment was 0.59 +/- 1.05 (p < 0.001). The average analgesic use score before treatment was 3.07 +/- 1.46, whereas it was 1.86 +/- 1.90 after treatment (p < 0.001). There was no evidence of clinical complications. CONCLUSION Vesselplasty offers statistically significant benefits in improvements of pain, mobility, and the need for analgesia in patients with symptomatic VCFs, thus providing a safe alternative in the treatment of these fractures.
An empirical analysis of the antecedents of adoption of online services: A prototype-based framework

Purpose – Online services have replaced many services that were delivered through other avenues. However, adoption of them has varied significantly. This paper seeks to expand on technology adoption theories by integrating them with those exploring service innovation and attempts to explore factors that help or hinder the attitude towards using online services. Thus, the study aims to provide insight into attributes to which developers and designers of such services should pay attention.Design/methodology/approach – The study accomplishes the purpose stated above through testing a framework that was developed as a result of critical literature review, interviews, a brainstorming session, an expert focus group and a final large‐scale survey. A set of prototypes was developed as alternative interfaces for the online service.Findings – In addition to finding that usefulness and ease of use are affecting the intention to use in the case of online services, the paper also identified that users were positively .
Characterization of HLA‐F polymorphism in four distinct populations in Mainland China

Currently, there is a lack of information on polymorphism of human leucocyte antigen‐F (HLA‐F) gene in ethnically diverse human populations. In this study, HLA‐F allelic typing was performed for 690 individuals representing two southern Chinese Han populations (Hunan Han and Guangdong Han) and two northern Chinese populations (Inner Mongolia Han and Inner Mongolia Mongol), using polymerase chain reaction‐sequence‐specific priming (PCR‐SSP) and PCR‐sequencing methods. Our results showed that (i) HLA‐F*01 : 01 predominated in each population with a frequency >0.94 and HLA‐F*01 : 03 was relatively more common in the two northern Chinese populations with a frequency of approximately 0.05; (ii) both geographical and ethnical factors are related to HLA‐F allelic distribution, as evidenced by the significant difference in HLA‐F allelic distribution between the Hunan Han population and the two northern Chinese populations; (iii) significant linkage disequilibrium (LD) was observed for haplotype HLA‐A*03‐F*01 : 03 in three populations. In most cases, this haplotype extended to HLA‐E*01 : 03; and (iv) Ewens–Watterson homozygosity statistic at the HLA‐F locus did not depart significantly from expectation in each of the four populations. Our data revealed a low level of HLA‐F allelic variation in Chinese populations, suggesting that HLA‐F gene may have existed before some of the HLA‐A polymorphism and have been evolving under neutrality.
Testing the Recovery of Intrinsic Galaxy Sizes and Masses of z ∼ 2 Massive Galaxies Using Cosmological Simulations

Accurate measurements of galaxy masses and sizes are key to tracing galaxy evolution over time. Cosmological zoom-in simulations provide an ideal test bed for assessing the recovery of galaxy properties from observations. Here, we utilize galaxies with at z ∼ 1.7–2 from the MassiveFIRE cosmological simulation suite, part of the Feedback in Realistic Environments (FIRE) project. Using mock multi-band images, we compare intrinsic galaxy masses and sizes to observational estimates. We find that observations accurately recover stellar masses, with a slight average underestimate of and scatter. Recovered half-light radii agree well with intrinsic half-mass radii when averaged over all viewing angles, with a systematic offset of (with the half-light radii being larger) and a scatter of . When using color gradients to account for mass-to-light variations, recovered half-mass radii also exceed the intrinsic half-mass radii by . However, if not properly accounted for, aperture effects can bias size estimates by . No differences are found between the mass and size offsets for star-forming and quiescent galaxies. Variations in viewing angle are responsible for ∼25% of the scatter in the recovered masses and sizes. Our results thus suggest that the intrinsic scatter in the mass–size relation may have previously been overestimated by ∼25%. Moreover, orientation-driven scatter causes the number density of very massive galaxies to be overestimated by at .
Contribution of the basolateral isoform of the Na-K-2Cl- cotransporter (NKCC1/BSC2) to renin secretion.

Acute administration of loop diuretics like furosemide leads to a stimulation of renin secretion, an effect thought to result from inhibition of Na-K-2Cl cotransporter (NKCC2)-mediated salt transport at the luminal surface of the macula densa (MD). However, loop diuretics also inhibit NKCC1, the second isoform of the Na-K-2Cl cotransporter, with similar potency. In the present study, we examined the influence of furosemide on renin secretion in NKCC1-deficient mice to distinguish between effects of the loop diuretic involving NKCC2 and, by implication, the MD pathway, and effects that might occur via inhibition of NKCC1. Baseline plasma renin concentration (PRC) was 1,212 +/- 211 in NKCC1+/+ (n = 13) and 3,851 +/- 579 ng ANG I.ml(-1). h(-1) in NKCC1-/- mice (n = 14; P = 0.00024). Acute administration of furosemide (50 mg/kg i.p.) increased PRC significantly to 9,324 +/- 1,018 ng ANG I.ml(-1). h(-1) in NKCC1+/+ (n = 13; P < 0.0001 compared with basal) and to 14,188 +/- 2,274 ng ANG I.ml(-1). h(-1) in NKCC1-/- mice [n = 14; P = 0.0002 compared with basal; P = 0.034 compared with wild-type (WT) plus furosemide]. Renin mRNA expression was about threefold higher in NKCC1-/- compared with WT mice. There was considerable recruitment of granular cells to upstream regions of afferent arterioles in NKCC1-/- mice. Patch-clamp studies in single juxtaglomerular granular (JG) cells from WT mice showed an approximately 10% increase in membrane capacitance during incubation with furosemide (10(-4) M), indicating a direct effect of the loop diuretic on renin secretion. No effect of furosemide on membrane capacitance was observed in JG cells from NKCC1-deficient mice. Furosemide (10(-3) M) significantly stimulated renin release from primary cultures of JG cells from WT mice, whereas no response was observed in NKCC1-/- mice. Our data suggest that a functional NKCC1 suppresses basal renin release, at least in part, through a direct effect on JG cells.
Protein stabilization with a dipeptide‐mimic triazine‐scaffolded synthetic affinity ligand

Protein stabilization was achieved by a novel approach based on the adsorption and establishment of affinity‐like interactions with a biomimetic triazine‐scaffolded ligand. A synthetic lead compound (ligand 3′/11, Ka ≈ 104 M−1) was selected from a previously screened solid‐phase library of affinity ligands for studies of adsorption and stabilization of cutinase from Fusarium solani pisi used as a model system. This ligand, directly synthesized in agarose by a well‐established solid‐phase synthesis method, was able to strongly bind cutinase and led to impressive half‐lives of more than 8 h at 70 °C, and of approximately 34 h at 60 °C for bound protein (a 25‐ and 57‐fold increase as compared with the free enzyme, respectively). The ligand density in the solid matrix was found to be a determinant parameter for cutinase stabilization. It is conceivable that the highly stabilizing effect observed results from the binding of more than one ligand residue to the enzyme, creating specific macromolecular configurations that lock structural mobility thus improving molecular stability.

Prediction of Peptide and Protein Propensity for Amyloid Formation

Understanding which peptides and proteins have the potential to undergo amyloid formation and what driving forces are responsible for amyloid-like fiber formation and stabilization remains limited. This is mainly because proteins that can undergo structural changes, which lead to amyloid formation, are quite diverse and share no obvious sequence or structural homology, despite the structural similarity found in the fibrils. To address these issues, a novel approach based on recursive feature selection and feed-forward neural networks was undertaken to identify key features highly correlated with the self-assembly problem. This approach allowed the identification of seven physicochemical and biochemical properties of the amino acids highly associated with the self-assembly of peptides and proteins into amyloid-like fibrils (normalized frequency of β-sheet, normalized frequency of β-sheet from LG, weights for β-sheet at the window position of 1, isoelectric point, atom-based hydrophobic moment, helix termination parameter at position j+1 and ΔG° values for peptides extrapolated in 0 M urea). Moreover, these features enabled the development of a new predictor (available at http://cran.r-project.org/web/packages/appnn/index.html) capable of accurately and reliably predicting the amyloidogenic propensity from the polypeptide sequence alone with a prediction accuracy of 84.9 % against an external validation dataset of sequences with experimental in vitro, evidence of amyloid formation.
Predator Diversity and Abundance Provide Little Support for the Enemies Hypothesis in Forests of High Tree Diversity

Predatory arthropods can exert strong top-down control on ecosystem functions. However, despite extensive theory and experimental manipulations of predator diversity, our knowledge about relationships between plant and predator diversity—and thus information on the relevance of experimental findings—for species-rich, natural ecosystems is limited. We studied activity abundance and species richness of epigeic spiders in a highly diverse forest ecosystem in subtropical China across 27 forest stands which formed a gradient in tree diversity of 25–69 species per plot. The enemies hypothesis predicts higher predator abundance and diversity, and concomitantly more effective top-down control of food webs, with increasing plant diversity. However, in our study, activity abundance and observed species richness of spiders decreased with increasing tree species richness. There was only a weak, non-significant relationship with tree richness when spider richness was rarefied, i.e. corrected for different total abundances of spiders. Only foraging guild richness (i.e. the diversity of hunting modes) of spiders was positively related to tree species richness. Plant species richness in the herb layer had no significant effects on spiders. Our results thus provide little support for the enemies hypothesis—derived from studies in less diverse ecosystems—of a positive relationship between predator and plant diversity. Our findings for an important group of generalist predators question whether stronger top-down control of food webs can be expected in the more plant diverse stands of our forest ecosystem. Biotic interactions could play important roles in mediating the observed relationships between spider and plant diversity, but further testing is required for a more detailed mechanistic understanding. Our findings have implications for evaluating the way in which theoretical predictions and experimental findings of functional predator effects apply to species-rich forest ecosystems, in which trophic interactions are often considered to be of crucial importance for the maintenance of high plant diversity.
Endoscopic management of cerebrospinal fluid leaks and cephaloceles

The excellent visualization and atraumatic surgical techniques of endoscopic sinus surgery have been applied to the management of five cerebrospinal fluid leaks and two nasal cephaloceles. In all cases, the exact site of the lesion was identified. Four cerebrospinal fluid leaks were grafted with a free or pedicled septal mucosal graft. The fifth cerebrospinal fluid leak came from a narrow sphenoethmoid recess and stopped after the mucosa was abraded. The two cephaloceles were reduced intranasally and covered with bone and mucosal grafts. Not all cases seen in the same time period were treated endoscopically; two additional cerebrospinal fluid leaks were treated with conventional techniques because of severe nasal inflammatory disease and intracranial complications. The technique and indications for endoscopic management of cerebrospinal fluid leaks and cephaloceles are discussed.
Suppression of a mutation in OmpR at the putative phosphorylation center by a mutant EnvZ protein in Escherichia coli

Phosphorylation of OmpR, a transcription activator for ompF and ompC expression, is essential for its function and has been shown to be mediated in vitro by EnvZ, a transmembrane sensory receptor protein. On the basis of the three-dimensional structure of CheY which has an extensive sequence similarity with OmpR, three aspartic residues, D11, D12, and D55, of OmpR are considered to form a triacidic pocket serving as the phosphorylation center. When these aspartic acid residues were replaced with asparagine (D11N) or glutamine (D12Q and D55Q), ompF and ompC expression was almost completely blocked. Two pseudorevertants of the D11N mutation were isolated: one of them is a mutation in EnvZ (G240E), and the other is a mutation in OmpR (S48F). The envZ mutation (G240E) by itself was found to confer a phenotype very similar to that of the well known envZ11 mutation (T247R), suggesting that EnvZ (G240E) is an elevated kinase for OmpR. Consistent with this notion, EnvZ (T247R) was also able to suppress the D11N mutation in OmpR. An in vitro phosphorylation study showed that while the wild-type OmpR was phosphorylated by EnvZ, the D11N OmpR was not. These results suggest that the D11N mutation alters OmpR conformation in such a way that OmpR is very poorly phosphorylated by EnvZ. On the basis of the in vivo and in vitro analysis, the mechanisms by which the G240E mutation in EnvZ and the S48F mutation in OmpR suppress the D11N mutation in OmpR are discussed.
Do Users Focus on the Correct Cues to Differentiate Between Phishing and Genuine Emails?

This paper examines the cues that typically differentiate phishing emails from genuine emails. The research is conducted in two stages. In the first stage, we identify the cues that actually differentiate between phishing and genuine emails. These are the consistency and personalisation of the message, the perceived legitimacy of links and sender, and the presence of spelling or grammatical irregularities. In the second stage, we identify the cues that participants use to differentiate between phishing and genuine emails. This revealed that participants often use cues that are not good indicators of whether an email is phishing or genuine. This includes the presence of legal disclaimers, the quality of visual presentation, and the positive consequences emphasised in the email. This study has implications for education and training and provides a basis for the design and development of targeted and more relevant training and risk communication strategies.
Cost Estimation of Road Traffic Injuries Among Iranian Motorcyclists Using the Willingness to Pay Method

Background Motorcycle riders are amongst some of the most vulnerable road users. The burden of motorcycles injuries from low and middle income countries is under-reported. Objectives In this study, the cost of traffic injuries among motorcyclists was calculated using the willingness to pay (WTP) method in Iran in 2013. Patients and Methods In a cross-sectional study, 143 motorcyclists were randomly selected. The research questionnaire was prepared based on the standard WTP method [stated preference (SP), contingent value (CV) and revealed preference (RP) models] taking into consideration perceived risks, especially those in Iran. Data were collected by a scenario for motorcyclists. The criteria for inclusion in the study consisted of having at least a high school education and being in the age range of 18 - 65 years. The final analysis of the WTP data was performed using the Weibull model. Results The mean WTP was 888,110 IRR (Iranian Rial) among motorcyclists. The statistical value of life was estimated according to 4694 death cases as 3,146,225,350,943 IRR, which was equivalent to USD 104,874,178 based on the dollar free market rate of 30,000 IRR (purchasing power parity). The cost of injury was 6,903,839,551,000 IRR, equivalent to USD 230,127,985 (based upon 73,325 injured motorcyclists in 2013, a daily traffic volume of 311, and a daily payment of 12,110 IRR for 250 working days). In total, injury and death cases came to 10,050,094,901,943 IRR, equivalent to USD 335,003,163. Willingness to pay had a significant relationship with having experienced an accident, the length of the daily trip (in km), and helmet use (P < 0.001). Conclusions Willingness to pay can be affected by experiencing an accident, the distance of the daily trip, and helmet use. The cost of traffic injuries among motorcyclists shows that this rate is much higher than the global average. Thus, expenditure should be made on effective initiatives such as the safety of motorcyclists.
Genetic and epigenetic catalysts in early-life programming of adult cardiometabolic disorders

Evidence has emerged across the past few decades that the lifetime risk of developing morbidities like type 2 diabetes, obesity, and cardiovascular disease may be influenced by exposures that occur in utero and in childhood. Developmental abnormalities are known to occur at various stages in fetal growth. Epidemiological and mechanistic studies have sought to delineate developmental processes and plausible risk factors influencing pregnancy outcomes and later health. Whether these observations reflect causal processes or are confounded by genetic and social factors remains unclear, although animal (and some human) studies suggest that epigenetic programming events may be involved. Regardless of the causal basis to observations of early-life risk factors and later disease risk, the fact that such associations exist and that they are of a fairly large magnitude justifies further research around this topic. Furthermore, additional information is needed to substantiate public health guidelines on lifestyle behaviors during pregnancy to improve infant health outcomes. Indeed, lifestyle intervention clinical trials in pregnancy are now coming online, where materials and data are being collected that should facilitate understanding of the causal nature of intrauterine exposures related with gestational weight gain, such as elevated maternal blood glucose concentrations. In this review, we provide an overview of these concepts.
PARASITES IN A BIODIVERSITY HOTSPOT: A SURVEY OF HEMATOZOA AND A MOLECULAR PHYLOGENETIC ANALYSIS OF PLASMODIUM IN NEW GUINEA SKINKS

A sample of 204 skinks (Squamata: Scincidae) from 10 genera representing 24 species were collected from 10 different localities in New Guinea and examined for blood parasites. Hemogregarines, trypanosomes, microfilarial worms, and 8 infections showing 2 distinct morphological types of malaria parasites (Plasmodium sp.) were observed. Molecular sequence data, in the form of mitochondrial cytochrome b sequences from the Plasmodium infections, showed 2 distinct clades of parasites, 1 in Sphenomorphus jobiense hosts and 1 in Emoia spp. , which correspond to the 2 morphotypes. There was substantial genetic variation between the 2 clades, as well as within the clade of Emoia parasites. Nearly half of the skinks sampled had green blood pigmentation, resulting from the presence of biliverdin in the plasma; however, only 1 of these lizards was infected with Plasmodium sp. and only 2 had any blood parasites. These preliminary results suggest a high degree of phylogenetic diversity but a very low prevalence of Plasmodium spp. infections in the skinks of this globally important biodiversity hot spot.
