Highly transparent, UV‐B protective Al–Zn–O films with potential application in greenhouse screen systems
Authors: Kosari Mehr Abbas , Hantehzadeh Mohammad Reza , Darabi Elham 
Published: January 2019

AbstractExtremely thin, Al–Zn–O composite films (21 ± 6 nm) are deposited on fused silica substrates under various percentages of oxygen in the oxygen/argon gas mixture (3%, 4.5%, 6%, and 7.5%). The films are prepared by a cylindrical DC magnetron sputtering system, utilizing a single compound target. The effects of the oxygen percentage on the compositional, morphological, and optical properties of the films are investigated by energy‐dispersive X‐ray spectroscopy, scanning electron microscopy, UV‐visible spectrophotometry, and atomic force microscopy. The chemical composition of the films is Al1 Zn1+X O with 0.2 < X < 1. The average visible transmittance of 93.6% with a high level of uniformity is obtained when the sputtering deposition performs under the oxygen percentage of 6%. It is found that the optical band gap of the films can be tailored toward higher energy by increasing oxygen percentage; however, the adjustable range is not so significant. The results offer cost‐efficient films with high, uniform transmittance in the visible region and with an ability to attenuate more than 10% of incident UV‐B radiation (280‐315 nm). This type of films can potentially be included in greenhouse screen systems to effectively protect the plants from the elevated UV‐B radiation without altering natural conditions.

Published: January 2019

BackgroundSilver diamine fluoride (SDF) causes dental black staining after its application.AimEvaluate the aesthetic perception, acceptability, and/or satisfaction of patients, parents, and professionals to the treatment of caries lesions with SDF through a scoping review.DesignA search was performed in seven databases and two key journals with no language or date restrictions. Studies that evaluated the aesthetic perception, satisfaction, and/or acceptability of patients, parents, and professionals to the treatment of carious lesions with SDF were considered eligible.ResultsFrom a total of 1177 articles, 10 studies were full text assessed for eligibility, with nine included in this scoping review. In general, the studies varied by population, study design, and methodologic evaluation. The type of tooth (anterior or posterior), family income, parental schooling, ethnicity, and need for advanced behaviour control methods were factors that influenced the results. The acceptability level increased as the child required more advanced methods of behaviour guidance. In general, the pigmentation caused by SDF did not interfere with the parents’ acceptability of the treatment; however, professionals believe that this could have influence. Regarding satisfaction, pigmentation did not influence parental satisfaction.ConclusionParents were satisfied with and found SDF acceptable, whereas professionals did not.

Published: January 2019

AbstractHigh‐strength zirconia (ZrO2) continuous fibers, which are potential candidates as ultra‐high temperature thermal insulators and reinforced materials, are typically fabricated by dry spinning an organozirconium precursor. However, the uncontrolled decomposition of organozirconium precursor usually occurs upon heat treatment that breaks the continuous fibers into pieces, resulting in the loss of tensile strength. Herein, in this contribution, we aimed to maintain the integrity of ZrO2 precursor fibers during heat treatment. For this purpose, novel high‐pressure vapor (HPV) pretreatment of ZrO2 precursor fiber was introduced. The HPV pretreatment is considered to be efficient for the removal of the organics in precursor, promoting the formation of amorphous structures of Zr(OH)4 and Zr(OH)3HCO3. Combining the studies of microstructures and tensile strengths, it was found that the amorphous structures played roles of cross‐linking points, keeping the fibers integrity during the followed heat treatment. After HPV pretreatment, the high‐strength ZrO2 continuous fibers would be obtained by direct sintering in air without any atmosphere which substantially lowered the cost. The tensile strengths of sintered ZrO2 continuous fibers pretreated by an optimized HPV procedure could reach up to as high as 1.299 GPa. The HPV pretreatment method provides a high‐efficiency, low‐cost technique for preparing high‐quality ceramic fibers.

Published: January 2019

Previously, we reported that magnetic stimulation of carotid sinus (MSCS) could lower arterial pressure in rabbits. In this randomized, sham‐controlled pilot study, we evaluated the effects of MSCS on blood pressure in pre‐hypertensive and hypertensive subjects. A total of 15 subjects with blood pressure higher than 130/80 mm Hg were randomized to receive sham or 1Hz MSCS. The changes of systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MAP) during treatment were compared between groups. The heart rate variability (HRV) and baroreflex sensitivity (BRS) before, during, and after treatments were analyzed. Reduction of SBP was significantly greater in subjects with MSCS than those with sham stimulation (6.6 ± 0.4 vs −2.5 ± 0.4 mm Hg, P < 0.001). Reduction of DBP was significantly greater in subjects with MSCS than those with sham stimulation (1.2 ± 0.2 vs −2.8 ± 0.2 mm Hg, P < 0.001). Reduction of MAP was significantly greater in subjects with MSCS than those with sham stimulation (1.4 ± 0.3 mm Hg vs −4.0 ± 0.3 mm Hg, P < 0.001). Reduction of HR was significantly greater in subjects with MSCS than those with sham stimulation (0.5 ± 0.5 vs −1.9 ± 0.3 beats/min, P = 0.002). BRS increased from 6.85 ± 0.77 to 8.79 ± 0.95 ms/mm Hg after MSCS compared with that at baseline (P = 0.027). Thus, MSCS can lower blood pressure and heart rate in pre‐hypertensive and hypertensive subject, warranting further study for establishing MSCS as a treatment for hypertension.

AbstractTn antigen is a truncated O‐glycan, frequently detected in colorectal cancer (CRC), but its precise role in CRC metastasis is not well addressed. Here we investigated the effects of Core 1 β3Gal‐T specific molecular chaperone (Cosmc) deletion‐mediated Tn antigen exposure on CRC metastasis and its underlying mechanism. We first used CRISPR/Cas9 technology to knockout Cosmc, which is required for normal O‐glycosylation, and thereby obtained Tn‐positive CRC cells. We then investigated the biological consequences of Tn antigen expression in CRC. The results showed that Tn‐positive cells exhibited an enhanced metastatic capability both in vitro and in vivo. A further analysis indicated that Tn antigen expression induced typical activation of epithelial‐mesenchymal transition (EMT). Mechanistically, we found that H‐Ras, which is known to drive EMT, was markedly up‐regulated in Tn‐positive cells, whereas knockdown of H‐Ras suppressed Tn antigen induced activation of EMT. Furthermore, we confirmed that LS174T cells (Tn‐positive) transfected with wild‐type Cosmc, thus expressing no Tn antigen, had down‐regulation of H‐Ras expression and subsequent inhibition of EMT process. In addition, analysis of 438 samples in TCGA cohort demonstrated that Cosmc expression was reversely correlated with H‐Ras, underscoring the significance of Tn antigen‐H‐Ras signalling in CRC patients. These data demonstrated that Cosmc deletion‐mediated Tn antigen exposure promotes CRC metastasis, which is possibly mediated by H‐Ras‐induced EMT activation.

AbstractHere, we report phenotypic differences and similarities of monozygotic twins with maturity‐onset diabetes of the young type 5 harboring a partial deletion of chromosome 17q12. The proband and her twin sister manifested complete aplasia and marked hypoplasia, respectively, of the body and tail of the pancreas. Whereas both twins showed marked hypoplasia of the right kidney and multiple cysts in both kidneys, only the proband's sister showed hydronephrosis in the left kidney. The proband had profound defects in insulin and glucagon secretion, as well as mild renal dysfunction, whereas her sister had pronounced renal dysfunction accompanied by mild defects in insulin and glucagon secretion. Both twins manifested hypomagnesemia and hyperuricemia, but no apparent liver dysfunction or intellectual disability. The severity of renal and pancreatic defects differed between monozygotic twins with maturity‐onset diabetes of the young type 5, suggesting that the phenotypes of this condition are determined not solely by genetic factors.
DIVERGENCE OF OPINION AND LONG‐RUN PERFORMANCE OF PRIVATE PLACEMENTS: EVIDENCE FROM THE AUCTION MARKET
Authors: Han Jianlei , Pan Zheyao , Zhang Guangli 
Published: January 2019

AbstractIn this article, we propose and construct a direct measure of investors’ divergence of opinion based on auction bids data from private placements in China. We find that firms with higher bids dispersion generate lower long‐run stock returns after the issuance of private placements. This effect is economically significant and robust when controlling for market discount, earnings management, alternative dispersion measures, and self‐selection bias. Moreover, this negative relation is stronger for stocks with more stringent short‐sale constraints. Our findings therefore provide strong evidence for the overvaluation hypothesis.
Effects of different blowing agents on physical properties of extruded puffed snacks made from yellow pea and red lentil flours

Published: January 2019

AbstractPulse flours are nutritionally dense ingredients that can increase protein and fiber contents of extruded foods to create healthier snacks. However, extruding with such ingredients can deteriorate desirable physical properties such as expansion. The use of physical blowing agents (e.g., gases) can counter this. In this study, N2 and CO2 gases were used to investigate the impact of blowing agents on physical properties of red lentil and yellow pea extrudates. Microscopy imaging of extrudate cross‐sections showed increased number of cells brought about by gas injection. Some textural parameters, such as crunchiness, were positively affected by gas use regardless of pulse type, whereas others, such as bowl life, were a function of both pulse and gas type. The greatest changes in overall extrudate color and lightness were observed for red lentil with N2 gas injection. The use of physical blowing agents during food extrusion presents great potential in manipulating extrudate expansion, microstructure, texture, and color, with N2 gas well suited for red lentil extrudates in dry form and CO2 gas well suited for yellow pea extrudates in wet form.Practical applicationsPhysical blowing agent‐assisted extrusion is a novel technology for the food industry's ability to control aerated food structure and texture. As such, the concentration and solubility of blowing agents may be manipulated to enhance the physical properties of high protein‐ and high fiber‐aerated foods, including ready‐to‐eat snacks, breakfast cereals, and gluten‐free products. The use of physical blowing agent‐assisted extrusion has tremendous potential for the development of nutritionally dense, plant‐based aerated foods with consumer appeal. The results obtained are useful for the food industry because incorporation of such food products into our daily diets, through processing them using innovative technologies, not only adds value to plants (e.g., pulses and cereals) but also has potential health, economic, and ecological benefits for the society.

Published: January 2019

AbstractThe aim of this study was to investigate the effects of autochthonous Lactobacillus plantarum strains (S50, S51, S72, S74, and S85) as starter cultures on growth of Listeria monocytogenes in sucuk (Turkish dry fermented sausage) production. The counts of L. monocytogenes, lactic acid bacteria, and Enterobacteriaceae as well as pH value and moisture content were determined in sucuk during ripening period. L. monocytogenes, lactic acid bacteria, and pH value were significantly affected (p < 0.01) by both starter culture and ripening period. A slight increase in L. monocytogenes count was observed in the control group whereas a reduction was observed in samples produced with L. plantarum strains at the first day of fermentation. Although L. monocytogenes reduction in control group with spontaneous microbiota was 0.54 log cfu/g after 11 days of ripening, reductions of as high as 2.74 log cfu/g was observed in the presence of L. plantarum S50.Practical applicationsIn the current study, five different autochthonous Lactobacillus plantarum isolates were identified, the effects of these strains on the behavior of Listeria monocytogenes in Turkish fermented sausage (sucuk) were determined. To the best of our knowledge, this is the first report investigating the effects of autochthonous lactic acid bacteria strains on behavior of L. monocytogenes in sucuk fermentation. As starter culture autochthonous lactic acid bacteria can be more competitive than commercial types. Our findings reveal the importance of the use of these autochthonous L. plantarum strains causes rapid pH drop to inhibit L. monocytogenes growth during sucuk fermentation. And also L. plantarum S50 strain may be more suitable for use as bioprotective culture or starter culture compared to other strains.

AbstractPurposeTo assess the impact of thermal cycling on flexural properties of denture base acrylic resin reinforced with microcrystalline cellulose (MCC) derived from oil palm empty fruit bunch (OPEFB).Materials and MethodsThe flexural strength and flexural modulus, following thermal cycling (5000 cycles of 5‐55°C) of 3 MCC‐reinforced poly methyl methacrylate (PMMA) specimens were compared with the conventional and commercially available high‐impact PMMA. The 3 test groups were represented by addition of various weight combinations of MCC and acrylic powders.ResultsAll 3 test groups with the addition of MCC demonstrated improved flexural strength and flexural modulus compared to the conventional resin, without and after thermal cycling. The highest mean flexural strength corresponded to the specimens reinforced with 5% MCC followed by 2% MCC.ConclusionAddition of MCC derived from OPEFB to PMMA may be a viable alternative to the existing, commercially available synthetic reinforced PMMA resins. The potential application of natural fillers in the fabrication of a reinforced denture base resin needs further study.
Redemption in a single low point story longitudinally predicts well‐being: The incremental validity of life story elements

Published: January 2019

AbstractObjectiveExtending research on the incremental validity of life story variables and the importance of particular kinds of story contexts, this paper tested the hypothesis that a single theme (narrative redemption) in a specific life story episode (the low point—or an episode that challenges the self) can predict well‐being, above and beyond covariates.MethodTwo samples, an emerging adult (N = 144) and a late midlife sample (N = 158), provided life story episodes with different life story collection methods (written and interview) and completed self‐report measures concurrently and longitudinally.ResultsThe findings indicated that low point redemption was associated concurrently and longitudinally with well‐being when controlling for the Big Five factors of Extraversion and Neuroticism and narrative word count. These associations held for three months among emerging adults and four years among late midlife adults. Aggregating redemption in high and low points did not improve the concurrent or longitudinal association between redemption and well‐being.ConclusionsThe findings demonstrate the capacity of elements in a single challenging episode of the life story to predict well‐being.

Published: January 2019

ABSTRACTBACKGROUNDDespite the environment being recognized as playing an important role in health, little is known about the influence of school and community factors on student health. This study aimed to identify the ecological factors influencing obesity among middle school students, including intrapersonal, interpersonal, school, and community factors.METHODSThe study sample consisted of 2069 students from 50 middle schools, with individual‐level data. School and community‐level data were collected using a school nurse survey and official materials from the National and Civic Statistics. These data were merged and used for a series of multilevel logistic regression analyses.RESULTSThere were significant variations in the students' overweight/obesity status, by ecological factors. Individual dietary habits, peer social support for physical activity, health education in the regular curriculum, the number of personal computer rooms per 100,000 individuals, and the area of public sports facilities per 100,000 individuals were significantly associated with student obesity.CONCLUSIONSTo be more effective, overweight/obesity prevention efforts for middle school students should focus not only on individual factors, but also on school and community factors.

Published: January 2019

ABSTRACTBACKGROUNDIn Colombia, the prevalence of overweight/obesity in children has increased by 26% in the past 5 years. School food environment may be an important contributor and offers opportunities for effective intervention.METHODSWe conducted a cross‐sectional study among 7‐ to 14‐year‐old schoolchildren from 10 schools in Bogotá, Colombia. We examined the school food environment and the relationship of individual‐level consumption, and physical activity with overweight/obesity, measured by body mass index and percentage body fat.RESULTSSchools with a restaurant/store were characterized as having excessive unhealthy foods. In the sample of 714 schoolchildren, 17.5% were overweight and 10.5% were obese. In multivariate models, boys had significantly increased odds of being overweight/obese (odds ratio [OR]: 1.53; p = .01) as compared to girls. Schoolchildren who consumed a greater number of energy drinks (OR = 1.82; p = .04), and those who spent more than 3 hours per schoolday watching TV (OR = 1.53; p < .01) had increased odds of being overweight/obese.CONCLUSIONSApproximately 1 in 4 schoolchildren were overweight/obese, with boys, energy drink consumers, and those with low physical activity having increased risk. School‐based interventions focused on improving food options and providing health behavior education may be effective to reduce overweight among children in Bogotá and similar settings.

Published: January 2019

ABSTRACTBACKGROUNDWith recent recommendations from professional organizations, long‐acting reversible contraception (LARC) methods are considered appropriate first‐line contraception for adolescents. Many school‐based health centers (SBHCs) in New York City (NYC) have recently added onsite LARC insertion and management to their contraceptive options. We aimed to explore key elements needed to implement LARC training and services into the SBHC setting and to identify successful factors for program implementation.METHODSSemistructured qualitative interviews were conducted with 19 providers and staff at 7 SBHCs in high schools in the Bronx and analyzed using Dedoose.RESULTSSupport and leadership from administration; comprehensive onsite training of providers and staff; developing an effective staffing model for procedure sessions; and patient‐centered contraceptive counseling were 4 key themes named by respondents as crucial to the program implementation process.CONCLUSIONSIntegrating LARC services onsite at SBHCs is feasible and positively received by providers and staff. With good leadership, staffing, training, and appropriate contraceptive counseling, both SBHCs and other primary clinics that serve adolescents can integrate LARC insertion, removal, and management into routine contraceptive care. This in turn can increase youth access to these methods.
