Published: July 2016

ABSTRACTIn this study, an investigation of the rheological behavior of starch/poly(vinyl alcohol) (PVA)/titanium oxide (TiO2) nanofluids was performed. It revealed that the rheological behavior of starch suspensions displays a particular change due to the presence of PVA and TiO2. All examined fluids demonstrated non‐Newtonian behavior and followed the Power law model. The main and interacting effects of starch, PVA, and TiO2 nanoparticles concentrations were studied using the analysis of variance. The results indicated that the flow behavior index (n), as well as the consistency index (K) of suspensions, is influenced by the PVA and TiO2 contents. The flow behavior index (n) decreased and consistency index (K) increased by an increase in PVA concentration. A reverse trend is observed by the addition of TiO2 nanoparticles to starch and PVA blend suspensions. The difference in rheological behaviors was ascribed to the presence of binary and triplet interactions between starch, PVA, and TiO2 nanoparticles. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

Published: July 2016

ABSTRACTIn this study, we present the first characterization of pure PEDOT:PSS aerogels fabricated via a facile and reproducible freeze–drying technique using no additional crosslinking agents, and it is demonstrated that these materials provide a promising path to new classes of polymeric thermoelectric materials. The morphology, chemical composition, and thermoelectric properties of these robust and mechanically stable aerogels were investigated upon treatment with ethylene glycol. By direct comparison to fully dense PEDOT:PSS thick films, it is shown that the electronic portion of thermoelectric transport in PEDOT:PSS was remarkably unaffected by morphological porosity, presenting exciting opportunities for novel soft materials that simultaneously integrate thermoelectric behavior while also capitalizing on the high surface area scaffolding accessible in such aerogel architectures. © 2016 Wiley Periodicals, Inc.

ObjectivePatients with systemic lupus erythematosus (SLE) have an increased risk of cardiovascular disease (CVD) and impaired endothelial repair. Although vitamin D deficiency is associated with increased CVD risk in the general population, a causal relationship has not been demonstrated. We aimed to determine whether vitamin D deficiency directly modulates endothelial dysfunction and immune responses in a murine model of SLE.MethodsVitamin D deficiency was induced in lupus‐prone MRL/lpr mice by dietary restriction for 6 weeks. Endothelium‐dependent vasorelaxation was quantified using aortic ring myography, and endothelial repair mechanisms were assessed by evaluating the phenotype and function of bone marrow endothelial progenitor cells (EPCs) and with the use of an in vivo Matrigel plug model. Lupus disease activity was determined by evaluating expression of interferon‐stimulated genes (ISGs) in splenic tissue, positivity for serum autoantibodies, and renal histology. To validate the findings, expression of ISGs was also measured in whole blood from vitamin D–deficient and vitamin D–sufficient patients with SLE.ResultsVitamin D deficiency resulted in impaired endothelium‐dependent vasorelaxation and decreases in neoangiogenesis without a change in the total number of EPCs. There were no differences in anti–double‐stranded DNA titers, proteinuria, or glomerulonephritis (activity or chronicity) between vitamin D–deficient or sufficient mice. Vitamin D deficiency was associated with a trend toward increased ISG expression both in mice and in patients with SLE.ConclusionThese findings indicate that vitamin D deficiency is associated with hampered vascular repair and reduced endothelial function, and may modulate type I interferon responses.

ObjectiveTo evaluate the efficacy and safety of ABT‐494, a selective JAK‐1 inhibitor, in patients with moderate‐to‐severe rheumatoid arthritis (RA) and an inadequate response to methotrexate (MTX).MethodsThree hundred RA patients receiving stable doses of MTX were randomly assigned equally to receive immediate‐release ABT‐494 at 3, 6, 12, or 18 mg twice daily, 24 mg once daily, or placebo for 12 weeks. The primary efficacy end point was the proportion of patients meeting the American College of Rheumatology 20% improvement criteria (achieving an ACR20 response) at week 12, as determined using the last observation carried forward method.ResultsAt week 12, the proportion of ACR20 responses was higher with ABT‐494 (62%, 68%, 80%, 64%, and 76% for the 3, 6, 12, 18, and 24 mg doses, respectively) than with placebo (46%) (using nonresponder imputation) (P < 0.05 for the 6, 12, and 24 mg doses). There was a significant dose‐response relationship among all ABT‐494 doses (P < 0.001). The proportions of patients achieving ACR50 and ACR70 responses were significantly higher for all ABT‐494 doses (except the 12 mg dose for the ACR70 response) than for placebo, as were changes in the Disease Activity Score in 28 joints using the C‐reactive protein level (DAS28‐CRP). Rapid improvement was demonstrated by significant differences in ACR20 response rates and changes in the DAS28‐CRP for all doses compared with placebo at week 2 (the first postbaseline visit). The incidence of adverse events was similar across groups; most were mild, and infections were the most frequent. One serious infection (community‐acquired pneumonia) occurred with ABT‐494 at 12 mg. There were dose‐dependent increases in high‐density lipoprotein (HDL) and low‐density lipoprotein (LDL) cholesterol, but the LDL cholesterol:HDL cholesterol ratios were unchanged through week 12. Mean hemoglobin levels remained stable at lower doses, but decreases were observed at higher doses.ConclusionThis study evaluated a broad range of doses of ABT‐494 in RA patients with an inadequate response to MTX. ABT‐494 demonstrated efficacy, with a safety and tolerability profile similar to that of other JAK inhibitors.

BackgroundNonsyndromic cleft with or without cleft palate (nsCL/P) is a common birth defect. Although genome‐wide association studies (GWAS) have identified numerous risk variants, a considerable fraction of the genetic heritability remains unknown. The aim of the present study was to replicate a previous finding that de novo deletions in a 62 kb region of chromosome 7p14 are a risk factor for nsCL/P, using an independent cohort.MethodsData from a published case–control GWAS cohort of 399 patients and 1318 controls were used. Copy number variant (CNV) detection in the 62 kb candidate region of 7p14 was performed using QuantiSNP. Putative CNVs in probands were verified and validated by quantitative polymerase chain reaction. Segregation analyses were performed in family members for whom DNA was available.ResultsWithin the 62 kb candidate region, a deletion of 7.4 kb showed association with nsCL/P (13/387 cases, 20/1300 controls, plowest = 0.024, odds ratio = 2.22). In all families with a sporadic case (n = 3), the deletion occurred de novo. In multiplex families, both incomplete segregation and incomplete penetrance were observed.ConclusionThe present data support the hypothesis that deletions at 7p14 are a common risk factor for nsCL/P. Genome‐wide CNV analyses in nsCL/P cohorts are warranted to explore the functional relevance of these deletions and their contribution to nsCL/P, and to determine exact breakpoints.

CBT reduces CBF: cognitive‐behavioral therapy reduces cerebral blood flow in fear‐relevant brain regions in spider phobia

Published: July 2016

AbstractBackgroundImaging studies have provided evidence that cognitive‐behavioral therapy (CBT) is able to change brain activation in phobic patients in response to threatening stimuli. The changes occurred in both emotion‐generating and modulatory regions. In this study, we use a data‐driven approach to explore resting state cerebral blood flow (CBF) measured by arterial spin labeling (ASL), before and after CBT.MethodsEight female patients with spider phobia were scanned before and 1 month after an exposure‐based group therapy for spider phobia. Each MRI session consisted of an ASL resting state measurement acquired before and after a symptom provocation task involving the showing of spider pictures in the scanner. The first ASL acquisition measured anticipatory anxiety and the second measured postprocessing of phobia‐relevant stimuli.ResultsCognitive‐behavioral therapy significantly reduced spider phobic symptoms in all patients. Symptom reduction during anticipatory anxiety was accompanied by reduced bilateral CBF in the parahippocampal gyrus, ventral anterior thalamus, Brodmann area 8, and the anterior cingulate cortex. During postprocessing of phobia‐relevant stimuli, patients showed reduced CBF in the bilateral insula, components of the motor cortex, and areas associated with language functions.ConclusionsLongitudinal CBF dynamics following CBT were in concordance with results from several studies using BOLD fMRI to investigate the effects of psychotherapy on brain activity. CBF can be quantified by ASL, with the principal advantage of sensitivity to slow variations in neural activity and task independence. Therefore, ASL may be a suitable method for monitoring and evaluating the efficacy of psychotherapy or pharmacotherapy approaches.

Published: July 2016

AbstractObjectivesIatrogenic spinal cord injuries (SCIs) caused by invasive procedures or surgical interventions have previously been reported as case studies. The primary objective of this study was to investigate and analyze the incidence, etiology, and prognosis of iatrogenic SCI in Western Norway.MethodsMedical records of all 183 patients admitted to the SCU between 01.01.2004 and 31.12.2013 were reviewed. Gender, age, diagnosis, iatrogenic medical procedure, symptoms and findings before and after injury, mechanism of injury, level of injury, and ASIA Impairment Scale (AIS) score prior iatrogenic SCI, at admittance and discharge were recorded, as were the length of the period prior to admittance and the length of stay.ResultsTwenty‐three (12.5%; 14 men, nine women) of 183 patients met the criteria for iatrogenic SCI. The annual incidence rate was estimated 2,3 per 1,000,000 (SD ±1.0). Mean age at iatrogenic SCI was 55.5 years (range 16–79 years). Intervention for cervical spinal stenosis was the leading cause of iatrogenic SCI, followed by operations on the aorta and spine. Iatrogenic SCIs was most frequently located on the thoracic level. The patients suffered from clinical incomplete injuries (AIS score C and D) both at admittance and discharge from the SCU. Most patients improved, but no patient recovered completely after SCI.ConclusionAlthough the annual incidence rate of iatrogenic SCI is low in Norway, individual consequences are serious. Increased awareness of the causes of SCI may decrease the risk of iatrogenic SCI.

AbstractCarotenoids and retinol are considered biomarkers of fruits and vegetables intake, and are of much interest because of their anti‐inflammatory and antioxidant properties; however, there is inconsistent evidence regarding their protective effects against lung cancer. We conducted a meta‐analysis of prospective studies of blood concentrations of carotenoids and retinol, and lung cancer risk. We identified relevant prospective studies published up to December 2014 by searching the PubMed and several other databases. We calculated summary estimates of lung cancer risk for the highest compared with lowest carotenoid and retinol concentrations and dose–response meta‐analyses using random effects models. We used fractional polynomial models to assess potential nonlinear relationships. Seventeen prospective studies (18 publications) including 3603 cases and 458,434 participants were included in the meta‐analysis. Blood concentrations of α‐carotene, β‐carotene, total carotenoids, and retinol were significantly inversely associated with lung cancer risk or mortality. The summary relative risk were 0.66 (95% confidence interval [CI]: 0.55–0.80) per 5 μg/100 mL of α‐carotene (studies [n] = 5), 0.84 (95% CI: 0.76–0.94) per 20 μg/100 mL of β‐carotene (n = 9), 0.66 (95% CI: 0.54–0.81) per 100 μg/100 mL of total carotenoids (n = 4), and 0.81 (95% CI: 0.73–0.90) per 70 μg/100 mL of retinol (n = 8). In stratified analysis by sex, the significant inverse associations for β‐carotene and retinol were observed only in men and not in women. Nonlinear associations were observed for β‐carotene, β‐cryptoxanthin, and lycopene, with stronger associations observed at lower concentrations. There were not enough data to conduct stratified analyses by smoking. In conclusion, higher blood concentrations of several carotenoids and retinol are associated with reduced lung cancer risk. Further studies in never and former smokers are needed to rule out confounding by smoking.
Generation of New Complestatin Analogues by Heterologous Expression of the Complestatin Biosynthetic Gene Cluster from Streptomyces chartreusis AN1542

Published: July 2016

AbstractThe heterologous expression of the biosynthetic gene cluster (BGC) of natural products enables the production of complex metabolites in a well‐characterized host, and facilitates the generation of novel analogues by the manipulation of the genes. However, the BGCs of glycopeptides such as vancomycin, teicoplanin, and complestatin are usually too large to be directly cloned into a single cosmid. Here, we describe the heterologous expression of the complestatin BGC. The 54.5 kb cluster was fully reconstituted from two overlapping cosmids into one cosmid by λ‐RED recombination‐mediated assembly. Heterologous expression of the assembled gene cluster in Streptomyces lividans TK24 resulted in the production of complestatin. Deletion of cytochrome P450 monooxygenase genes (open reading frames 10 and 11) and heterologous expression of the modified clusters led to the production of two new monocyclic and linear derivatives, complestatins M55 and S56.
