Development and Evaluation of a Screening Scale for Indirect Trauma Caused by Media Exposure to Social Disasters

As a result of mass media development, disaster-related information, such as the severity of damage, can be easily shared; thus, the issue of consequent indirect trauma has become as important as that of direct trauma. This study developed a scale to measure the degree of indirect trauma caused by media exposure to social disasters and then verified this scale’s reliability and validity. Initial items were developed through a literature review; 39 items were selected by examining their content validity and conducting a pretest. To verify the scale’s validity and reliability, exploratory factor analyses were conducted, and Cronbach’s alpha coefficients were calculated. The explanatory power of the screening scale developed through this study was 62.2%. The scale was ultimately composed of three factors comprising 24 items. Through exploratory factor analyses, factors were identified as “psychological, physical, and behavioral responses to social disasters” (factor 1), “moral resentment due to social disasters” (factor 2), and “a sense of threat to life due to social disasters” (factor 3). Regarding internal reliability, Cronbach’s alpha values ranged between 0.85 and 0.96. Future studies with expanded participant populations are suggested, which could further verify the scale’s validity and reliability and complement its shortcomings.

Combined analysis of Xylopia rubescens Oliv. leaf oil using gas chromatography with flame ionization detection, gas chromatography with mass spectrometry and 13C nuclear magnetic resonance: structure elucidation of new compounds

Phytochemicals have been isolated from extracts of various Xylopia species (Annonaceae) growing wild in the African rainforest. In contrast, no phytochemical investigations have been reported to date on Xylopia rubescens Oliv. The aim of the present work was to describe the composition of X. rubescens leaf oil. Analysis of the leaf oil has been undertaken by a combination of chromatographic and spectroscopic techniques. Three new compounds have been isolated and their structures elucidated as furanoguaia-1,4-diene, furanoguaia-1,3-diene and (8Z,11Z,14Z)-8,11,14-heptadecatrien-2-ol. One other compound is reported for the first time as a natural compound. The oil composition was dominated by both furanoguaiadienes (34.2% and 11.4%, respectively) and by (8Z,11Z,14Z)-8,11,14-heptadecatrien-2-one (12.8%). The composition of X. rubescens leaf oil varied dramatically from those of the essential oils isolated from other Xylopia species. Copyright © 2013 John Wiley & Sons, Ltd.
Living cationic polymerization of .alpha.-methylstyrene initiated with a vinyl ether-hydrogen chloride adduct in conjunction with tin tetrabromide

The first example of living cationic polymerization of α-methylstyrene was achieved with an initiating system that consist of the HCl-adduct of 2-chloroethyl vinyl ether [1a: CH 3 CH(OCH 2 CH 2 Cl)Cl] and SnBr 4 in CH 2 Cl 2 at -78°C. The number-average molecular weight of the polymers increased in direct proportion to monomer conversion up to 110 000 (DP n =1000) and agreed with the calculated values assuming that one polymer chain forms per 1a molecule. Throughout the reaction, the molecular weight distribution of the polymers stayed very narrow (M w /M n ∼1.1)
Body composition by bioelectrical impedance, muscle strength, and nutritional risk in oropharyngeal dysphagia patients.

INTRODUCTION oropharyngeal dysphagia (OD) has complications such as malnutrition and dehydration. Body composition is an important factor for nutritional status. OBJECTIVE to evaluate the presence of cachexia, phase angle, muscle strength, and nutritional risk according to the type of feeding regimen tolerated by patients, determined with the volume-viscosity swallow test (V-VST). METHODS this cross-sectional study included hospitalized adults of both sexes with a diagnosis of OD established by the Eating Assessment Tool and V-VST. Nutritional risk status was assesed using the Nutritional Risk Screening-2002 tool. Phase angle and cachexia were determined through bioelectrical impedance vector analysis (BIVA), and functional capacity through handgrip strength (HGS) and anthropometric parameters. RESULTS seventy-nine patients with a median age of 73 years (56-79 yrs) were included; 79.9 % of patients were categorized at nutritional risk. According to the V-VST, 27 (34.2 %) patients tolerated nectar viscosity; 27 (34.2 %) belonged to the spoon-thick and 25 (31.6 %) to the exclusive tube feeding groups. In the exclusive tube feeding group a lower phase angle (3.7° ± 0.9) and lower HGS of 9 kg (5-15) were observed in comparison to the nectar and spoon-thick groups (in both, 4.6° ± 1.1, p = 0.005), which featured 20 kg (16-31) and 19 kg (14-26), respectively (p = 0.03). CONCLUSION nutritional risk was present in 79.9 % of the study population. BIVA allows to evaluate the integrity of muscle mass and tissue hydration, both related to phase angle. A lower phase angle and HGS were observed in the exclusive tube feeding group. These factors are considered important for prognosis.
Controlled Synthesis and Energy Applications of One‐Dimensional Conducting Polymer Nanostructures: An Overview

The past decade has witnessed increasing attention in the synthesis, properties, and applications of one‐dimensional (1D) conducting polymer nanostructures. This overview first summarizes the synthetic strategies for various 1D nanostructures of conjugated polypyrrole (PPy), polyaniline (PANI), polythiophene (PTh), poly(p‐phenylenevinylene) (PPV) and derivatives thereof. By using template‐directed or template‐free methods, nanoscale rods, wires/fibers, belts/ribbons, tubes, arrays, or composites have been successfully synthesized. With their unique structures and advantageous characteristics (e.g., high conductivity, high carrier mobility, good electrochemical activity, large specific surface area, short and direct path for charge/ion transportation, good mechanical properties), 1D conducting polymer nanostructures are demonstrated to be very useful for energy applications. Next, their applications in solar cells, fuel cells, rechargeable lithium batteries, and electrochemical supercapacitors are highlighted, with a strong emphasis on recent literature examples. Finally, this review ends with a summary and some perspectives on the challenges and opportunities in this emerging area of research.
Microstructure and Mechanical Properties of AA7075 Aluminum Alloy Fabricated by Spark Plasma Sintering (SPS)

AA7075 aluminum alloy is widely used for several high-technology applications for its high mechanical strength to weight ratio but is still the subject of several studies seeking a further increase in its mechanical properties. A commercial powder is used, either as-received or after ball-milling. Dense AA7075 samples are prepared in one step by Spark Plasma Sintering, at 550 °C with a holding time of 15 min and a uniaxial pressure of 100 MPa. No additional heat treatment is performed. Laser granulometry, X-ray diffraction and optical- and scanning electron microscopy show that both grain size and morphology are preserved in the dense samples, due to the relatively low temperature and short sintering time used. The samples prepared using the ball-milled powder exhibit both higher Vickers microhardness and transverse fracture strength values than those prepared using the raw powder, reflecting the finer microstructure.
Associations of Insomnia Symptoms With Cognition in Persons With Heart Failure

Although cognitive impairment is common among persons with heart failure and negatively impacts self-care, hospitalization, and mortality, the associations between cognitive impairment and insomnia symptoms are not clearly understood. The purpose of this study was to explore these associations and examine if they are maintained after adjusting for relevant sociodemographic, clinical, and lifestyle factors. Guided by the Neurocognitive model of insomnia and sleep and the self-care conceptual model, a cross-sectional data analysis using parametric testing was conducted on the Health and Retirement Study wave 2016. Difficulty initiating sleep and early morning awakening, but not difficulty maintaining sleep were significantly associated with poorer cognitive performance in the bivariate and multivariate analysis. Our results are suggestive of different phenotypes of insomnia symptoms that may have different associations with cognition in persons with heart failure. Further research using objective measurements of insomnia symptoms and detailed neuropsychiatric testing of cognition is needed to confirm this conclusion.
Acute Effects of Global Postural Re-Education on Non-Specific Low Back Pain. Does Time-of-Day Play a Role?

Low back pain is one the most common forms of musculoskeletal disorders. Thus, several physiotherapeutic strategies (e.g., global postural re-education therapy) have been used for reducing low back pain. The aim of this study was to determinate if acute application of global postural re-education session associated effects are influenced by the time-of-day when this physical therapy is applied. Eight participants in a randomized, counterbalanced order were acutely tested both before and 24 h after a global postural re-education therapy session (10 min session) in three different time-of-day points; morning (i.e., AM; 7:00–9:00 h), midday (i.e., AM; 12:00–14:00 h) and afternoon (i.e., PM; 18:00–20:00 h). In each session, low back pain Visual Analogue Pain Scale [VAS]), flexibility, function capacity (Roland Morris Questionnaire [RMQ], and physical functioning Oswestry Disability Index [ODI]) were recorded. Results showed a pain reduction (VAS Scale) 24 h post Global postural re-education [GPR] session (p = 0.001) and increasing of flexibility pre-post GPR session in all the time-of-day points (morning, midday, and afternoon) (p = 0.001) while no differences were reported in RMQ (p = 0.969) and ODI (p = 0.767). Thus, acute GPR session produces the same effects on flexibility, low back pain, function capacity, and physical functioning values independently of time-of-day when it is applied.
Contrasting off‐line segmentation decisions with on‐line word segmentation during reading

In two experiments, we investigated the correspondences between off‐line word segmentation and on‐line segmentation processing during Chinese reading. In Experiment 1, participants were asked to read sentences which contained critical four‐character strings, and then, they were required to segment the same sentences into words in a later off‐line word segmentation task. For each item, participants were split into 1‐word segmenters (who segmented four‐character strings as a single word) and 2‐word segmenters (who segmented four‐character strings as 2 two‐character words). Thus, we split participants into two groups (1‐word segmenters and 2‐word segmenters) according to their off‐line segmentation bias. The data analysis showed no reliable group effect on all the measures. In order to avoid the heterogeneity of participants and stimuli in Experiment 1, two groups of participants (1‐word segmenters and 2‐word segmenters) and three types of critical four‐character string (1‐word strings, ambiguous strings, and 2‐word strings) were identified in a norming study in Experiment 2. Participants were required to read sentences containing these critical strings. There was no reliable group effect in Experiment 2, as was the case in Experiment 1. However, in Experiment 2, participants spent less time and made fewer fixations on 1‐word strings compared to ambiguous and 2‐word strings. These results indicate that the off‐line word segmentation preferences do not necessarily reflect on‐line word segmentation processing during Chinese reading and that Chinese readers exhibit flexibility such that word, or multiple constituent, segmentation commitments are made on‐line.
Salmonella Vaccine Vector System for Foot-and-Mouth Disease Virus and Evaluation of Its Efficacy with Virus-Like Particles

Foot-and-mouth disease virus (FMDV) causes a highly contagious and devastating disease in livestock animals and has a great potential to cause severe economic loss worldwide. The major antigen of FMDV capsid protein, VP1, contains the major B-cell epitope responsible for effectively eliciting protective humoral immunity. In this study, irradiated Salmonella Typhimurium (KST0666) were used as transgenic vectors containing stress-inducible plasmid pRECN-VP1 to deliver the VP1 protein from FMDV-type A/WH/CHA/09. Mice were orally inoculated with ATOMASal-L3 harboring pRECN-VP1, and FMDV virus-like particles, where (VLPFMDV)-specific humoral, mucosal, and cellular immune responses were evaluated. Mice vaccinated with attenuated Salmonella (KST0666) expressing VP1 (named KST0669) showed high levels of VLP-specific IgA in feces and IgG in serum, with high FMDV neutralization titer. Moreover, KST0669-vaccinated mice showed increased population of IFN-γ (type 1 T helper cells; Th1 cells)-, IL-5 (Th2 cells)-, and IL-17A (Th17 cells)-expressing CD4+ as well as activated CD8+ T cells (IFN-γ+CD8+ cells), detected by stimulating VLPFMDV. All data indicate that our Salmonella vector system successfully delivered FMDV VP1 to immune cells and that the humoral and cellular efficacy of the vaccine can be easily evaluated using VLPFMDV in a Biosafety Level I (BSL1) laboratory.
Specific Adsorption of Trace Amounts of Calcium and Strontium by Hydrous Oxides of Iron and Aluminum1

Freshly prepared Fe and Al hydrous oxide gels and the amorphous product of heating gibbsite selectively adsorbed traces of Ca and Sr from solutions containing a large excess (∼1M) of NaNO3. The fraction of the added Ca (Sr) adsorbed depended principally on the suspension pH, the amount of solid present, and to a lesser extent on the NaNO3 concentration. Significant Ca and Sr adsorption occurred on the Fe and Al gels, and heated gibbsite, at pH values below the points of zero charge (8.1, 9.4, and 8.3±0.1, respectively), indicating specific adsorption. The pH (± 0.10) at which 50% of the Ca was adsorbed (pH50) occurred at pH 7.15 for the Fe gel (0.093M Fe), 8.35 for the Al gel (0.093M Al), and 6.70 for the heated gibbsite (0.181M Al); for Sr, the pH50 values were 7.10, 9.00, and 6.45, respectively. For the Fe gel and heated gibbsite, an empirical model based on the law of mass action described the pH dependence of adsorption reasonably well and suggested that for each Ca or Sr fraction adsorbed, approximately one proton was released. Failure of the Al gel to fit this model may have resulted from its rapid aging.
Genetic variants in human BCL2L11 (BIM) are associated with ulcerative forms of Buruli ulcer

ABSTRACT Buruli ulcer (BU) is a devastating skin mycobacterial infection characterized by extensive cell death, which was previously suggested to be mediated by Bcl2-like protein 11 (BIM, encoded by the BCL2L11 gene). We here report the association of genetic variants in BCL2L11 with ulcerative forms of the disease in a cohort of 618 Beninese individuals. Our results show that regulation of apoptosis in humans contributes to BU lesions associated with worse prognosis, prompting for further investigation on the implementation of novel methods for earlier identification of at-risk patients.
Classification and identification of amino acids based on THz spectroscopy

Amino acids are important nutrient substances for life, and many of them have several isomerides, while only L-type amino acids can be absorbed by body as nutrients. So it is certain worth to accurately classify and identify amino acids. In this paper, terahertz time-domain spectroscopy (THz-TDS) was used to detect isomers of various amino acids to obtain their absorption spectra, and their spectral characteristics were analyzed and compared. Results show that not all isomerides of amino acids have unique spectral characteristics, causing the difficulty of classification and identification. To solve this problem, partial least squares discriminant analysis (PLS-DA), firstly, was performed on extracting principal component of THz spectroscopy and classifying amino acids. Moreover, variable selection (VS) was employed to optimize spectral interval of feature extraction to improve analysis effect. As a result, the optimal classification model was determined and most samples can be accurately classified. Secondly, for each class of amino acids, PLS-DA combined with VS was also applied to identify isomerides. This work provides a suggestion for material classification and identification with THz spectroscopy.
Ex vivo Retrieval of Mature Oocytes for Fertility Preservation in a Patient with Bilateral Borderline Ovarian Tumor

Abstract We report a case of ultrasound-guided ex vivo oocyte retrieval for fertility preservation in a woman with bilateral borderline ovarian tumor, for whom conventional transvaginal oocyte retrieval was deemed unsafe because of the increased risk of malignant cell spillage. Ovarian stimulation with gonadotropins was performed. Surgery was scheduled according to the ovarian response to exogenous gonadotropic stimulation; oophorectomized specimens were obtained by laparoscopy, and oocyte retrieval was performed ∼ 37 hours after the ovulatory trigger. The sum of 20 ovarian follicles were aspirated, and 16 oocytes were obtained. We performed vitrification of 12 metaphase II oocytes and 3 oocytes matured in vitro. Our result emphasizes the viability of ex vivo mature oocyte retrieval after controlled ovarian stimulation for those with high risk of malignant dissemination by conventional approach.
Genetic Admixture in the Population of Wild Apple (Malus sieversii) from the Tien Shan Mountains, Kazakhstan

There is growing attention given to gene flow between crops and the wild relatives as global landscapes have been rapidly converted into agricultural farm fields over the past century. Crop-to-wild introgression may advance the extinction risks of rare plants through demographic swamping and/or genetic swamping. Malus sieversii, the progenitor of the apple, is exclusively distributed along the Tien Shan mountains. Habitat fragmentation and hybridization between M. sieversii and the cultivated apples have been proposed to be the causal mechanism of the accelerated extinction risk. We examined the genetic diversity pattern of eleven wild and domesticated apple populations and assessed the gene flow between M. sieversii and the cultivated apples in Kazakhstan using thirteen nuclear microsatellite loci. On average, apple populations harbored fairly high within-population diversity, whereas population divergences were very low suggesting likely influence of human-mediated dispersal. Assignment results showed a split pattern between the cultivated and wild apples and frequent admixture among the apple populations. Coupled with the inflated contemporary migration rates, the admixture pattern might be the signature of increased human intervention within the recent past. Our study highlighted the prevalent crop to wild gene flow of apples occurring in Kazakhstan, proposing an accelerated risk of genetic swamping.
Will Life Extension Affect Our Social Judgments? Evidence That the Possibility of Indefinite Life Extension Increases Harshness Toward Social Transgressors

We tested the hypothesis that if indefinite life extension (ILE) through medical technologies were to become a reality, then people may become harsher in their judgment of social transgressors. In support of this hypothesis, we found that higher positive attitudes towards ILE technologies related to harshness in judgment of social transgressions (Study 1), and that making ILE plausible (compared to not plausible) led participants to endorse harsher punishments for social transgressors (Studies 2–3). We replicated this effect and found that it is not amplified by subliminal death primes, although the primes also increased harshness (Study 3). These results may have implications to understanding how social judgment may be affected by the prospect of ILE.

Development of a Human-Display Interface with Vibrotactile Feedback for Real-World Assistive Applications

It is important to operate devices with control panels and touch screens assisted by haptic feedback in mobile environments such as driving automobiles and electric power wheelchairs. A lot of consideration is needed to give accurate haptic feedback, especially, presenting clear touch feedback to the elderly and people with reduced sensation is a very critical issue from healthcare and safety perspectives. In this study, we aimed to identify the perceptual characteristics for the frequency and direction of haptic vibration on the touch screen with vehicle-driving vibration and to propose an efficient haptic system based on these characteristics. As a result, we demonstrated that the detection threshold shift decreased at frequencies above 210 Hz due to the contact pressure during active touch, but the detection threshold shift increased at below 210 Hz. We found that the detection thresholds were 0.30–0.45 gpeak with similar sensitivity in the 80–270 Hz range. The haptic system implemented by reflecting the experimental results achieved characteristics suitable for use scenarios in automobiles. Ultimately, it could provide practical guidelines for the development of touch screens to give accurate touch feedback in the real-world environment.
Stereometric characterization of Dinizia excelsa Ducke wood from Amazon rainforest using atomic force microscopy

Dinizia excelsa Ducke under three different cut conditions were carefully analyzed. The morphology and stereometry of different wood cutting surfaces (longitudinal radial, longitudinal tangential, and transversal) were studied by SEM and AFM. The results obtained in this study suggest that both the height parameters and the advanced stereometric parameters of the surfaces did not reveal a significant difference, indicating that the spatial patterns do not change according to the type of cut. In this way, the surface microtexture does not vary depending on the cut type. Similarly, the Hurst's coefficients did not show any significant difference in the spectrum of the PSD fractal region. On the other hand, Minkowski functionals presented a morphological difference between the samples. These results showed that the microtexture of the wood surface does not change as a function of the type of cut submitted to the same polishing process.
