Self-care ability and influencing factors in chronic heart failure patients

Objectives: To describe the self-care abilities and associated factors in chronic heart failure (CHF) patients. Methods: Participant characteristics, illness-related information, and self-care ability were investigated using self-report questionnaires and patient records for 91 CHF patients in Nantong University Affiliated Hospital, China. Results: On average, patients had medium- to low-level self-care abilities. Comprehensive self-care ability was positively influenced by higher education level, employment status, and income level. Patients who received health education and had sound heart function had better self-care abilities. Regression analysis showed that the factors influencing self-care ability included average monthly income, education level, and heart function grading. Conclusions: Self-care ability in CHF patients is, in general, in medium to low ranges, indicating that medical workers need to enhance self-care education for CHF patients to help them better understand their condition and help them gain the necessary skills for self-care. We conclude that, when conducting self-care education for patients, medical workers should tailor their approach based on the individual characteristics of the patient. Doing so would effectively promote patient knowledge, mobility, and treatment compliance.
Anterior-only transthoracic surgery for adult spinal tuberculosis

anterior decompression followed by posterior fusion has been the surgical management of choice in spinal tuberculosis. Due to theatre time being at a premium, we have evolved to anterior only debridement, allo- graft strut reconstruction and instrumentation for tuberculosis in the adult thoracic spine. The aim of this study was to review the safety and efficacy of this treatment. Methods Twenty-nine adult thoracic tuberculosis patients were identified where anterior-only surgery had been performed. These were all mid-thoracic TB as circumferential surgery is still favoured in thoracolumbar disease. The surgery was performed by a single surgeon at a tertiary hospital. A retrospective review of clinical notes and radiological studies was performed.
University of Birmingham T cell immunity and caregiving stress in young and older caregivers

Background: The present study aimed to examine the impact of caregiving stress and aging on parameters of T cell immunity using caregivers and controls across two age cohorts. Methods: Seventy-nine young and older caregivers (parents of children with developmental disabilities and spousal dementia caregivers, respectively) were compared to 76 non-caregiving controls. Participants completed questionnaires to provide information about socio-demographics, health behaviour, psychosocial and caregiving variables, and provided a blood sample. T cell senescence and exhaustion markers, thymic output, and serum CMV antibody titre were assessed. Results: Despite greater psychological morbidity (greater depression, anxiety, perceived stress) than controls, caregivers showed robust immunity for most T cell parameters with the exception of KLRG-1 (marker involved in T cell senescence pathway). Conclusions: A higher percentage of KLRG1 + T cells in caregivers could explain the poorer vaccination response that has previously been reported in this group. These data also suggest that the impact of caregiving per se on immunity is not uniform.
Allelopathic effects of Eucalyptus globulus Labill. on seed germination and seedling growth of eggplant (Solanum melongena L.)

Eucalyptus spp. are known to contain various substances that are allelopathic. The objective of this study was to determine allelopathic effects of various solvent extracts (aqueous, methanolic, ethyl acetate, acetonic and benzene) of Eucalyptus globulus leaves in five concentrations ( , , , and g/L) on seed germination and early seedling growth of eggplant cv. Black Beauty. The experiment was carried out using a completely randomized design arranged in factorial scheme with three replicates. The results showed that all extracts had inhibitory effects on germination and seedling growth although degree of their inhibitions was different. Methanolic extract had the highest inhibitory effect on germination percentage and rate, root and shoot lengths and fresh and dry weights of eggplant seedlings whereas aqueous extract followed by acetonic extract had the lowest inhibitory effects. In all extracts, the reduction in germination and growth of eggplant seedlings increased significantly with increasing concentration. The results suggest that leaf extracts of E. globulus had potent allelopathic activity although the activity differed depending on extract and concentration.
Hybrid Nanotubular Structures for Photoelectrocatalysis Or Energy Storage Devices

The results of an experimental study devoted to the synthesis and characterisation of hybrid materials based on nanotubes (NT) of TiO2 modified by polyaniline (PANI) are presented in this work. The results demonstrated the final material performs well when applied as photoanode for water-splitting or for energy storage devices. TiO2 NTs have been synthesized by anodization of Ti foils from organic solution containing fluorides. The process of electro-polymerization of aniline has been carried out by cyclic voltammetry, starting from acid aqueous solution of the monomer. The performance of the polymeric structure has been investigated under the different conditions of electropolymerisation. The electrochemical capacitance of the samples has been investigated by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and galvanostatic charge–discharge tests (CDT). Moreover, photocurrent tests were performed in order to evaluate their ability in exploit the light irradiation.
The Protective and Recovery Effects of Fish Oil Supplementation on Cedar Pollen-Induced Allergic Reactions in Mice

Obesity is associated with the production of pro-inflammatory cytokines and therefore can lead to worsening of allergic reactions. Thus, there is cross-talk between obesity and allergic reactions. In this study, we investigated whether the anti-obesity action of fish oil supplementation is involved in the anti-allergic action also induced by fish oil. We observed attenuation of cedar pollen-induced IgE serum increases in two experimental protocols: 15% fish oil supplementation for 8 weeks, which attenuated body weight increases compared with 15% soybean supplementation, and 4% fish oil supplementation for 2 weeks, which did not affect body weight increases compared with 4% soybean or 4% lard supplementation. The former but not the latter protocol attenuated sneezing after pollen challenge. Gene expression of TNF-α and IL-13, a Th2 cytokine, was moderately reduced in the trachea and nasal mucosa in mice fed fish oil supple- ments. In a third protocol, fish oil was administered for up to 15 weeks after a cedar pollen sensitization and challenge-induced increase in IgE levels. These levels decreased following fish oil supplementation but were almost unaffected by soybean oil supplementation. Surprisingly, the IL-13 gene expression level in the nasal mucosa and trachea was higher in the fish oil group than in the soybean oil group. These results suggest that fish oil supplementation before, during, or after antigen sensitization and challenge in mice helped to reduce cedar pollen-induced allergic reactions in- dependent of its anti-obesity action. Fish oil supplementation can also exhibit pro- or anti-inflammatory action against IL-13 expression depending on the experimental protocol.
Perfectionism and thoughts about having cosmetic surgery performed

Trait perfectionism, perfectionistic self-presentation, and thoughts about having cosmetic surgery performed (TAHCSP) were examined. In Study 1, perfectionistic self-promotion (PSP) and nondisplay of imperfection (NDP) correlated with TAHCSP in 292 university women. Both Study 2 (N - 527 university women and 209 university men) and Study 3 (N= 43 gym-going women and 52 gym-going men) replicated findings from Study 1. Studies 2 and 3 extended Study 1 by showing that (a) socially prescribed perfectionism (SPP) correlated with TAHCSP and (b) PSP, NDP, and SPP correlated with TAHCSP in women only. PSP and NDP mediated the relation between SPP and TAHCSP in studies 2 and 3. Results held after controlling for age and body mass index. Perfectionists' pursuit of appearance ideals, fault-finding predilection, and concern over others' evaluations may generate and maintain TAHCSP.
Interaction of Additive Noise and Nonlinear Dynamics in the Double-Gyre Wind-Driven Ocean Circulation

AbstractIn this paper the authors study the interactions of additive noise and nonlinear dynamics in a quasigeostrophic model of the double-gyre wind-driven ocean circulation. The recently developed framework of dynamically orthogonal field theory is used to determine the statistics of the flows that arise through successive bifurcations of the system as the ratio of forcing to friction is increased. This study focuses on the understanding of the role of the spatial and temporal coherence of the noise in the wind stress forcing. When the wind stress noise is temporally white, the statistics of the stochastic double-gyre flow does not depend on the spatial structure and amplitude of the noise. This implies that a spatially inhomogeneous noise forcing in the wind stress field only has an effect on the dynamics of the flow when the noise is temporally colored. The latter kind of stochastic forcing may cause more complex or more coherent dynamics depending on its spatial correlation properties.
College Sexual Assault Prevention Programs: A Literature Review

A critical literature review is employed to evaluate the efficacy of sexual assault (SA) prevention programs on college campuses with special attention to cross-cultural application. SA prevention programs are required on college campuses but are rarely evaluated for efficacy. This review draws upon information and recommendations of preeminent authors in the field of SA research, using information gathered from peerreviewed journals and textbook chapters in order to apply what is known about SA prevention and cultural supports for SA to the generation of culturally relevant SA prevention. The author explores how the cultural supports for SA, including gender roles and rape myths, vary across cultures and influence sexual victimization rates with an end goal of honoring cultural diversity and tailoring SA interventions to meet the needs of a multiethnic audience.
Gold Nanoparticle-Assisted Laser Surface Modification of Borosilicate Glass Substrates

This paper describes the photomodification of borosilicate glass substrates assembled with 40 nm diameter gold nanoparticles (Au NPs) with surface coverages ranging from 17 to 23% on excitation of the localized surface plasmon band of the NPs with a 532 nm nanosecond pulsed-laser beam. The laser irradiation allowed the splitting and fusion of NPs on the substrate surface and, at the same time, the formation of craters of less than 10 nm diameter at various places following one laser shot with a relatively high intensity of 460 or 370 mJ·cm−2·pulse−1 but well below the breakdown threshold of 25−40 J·cm−2·pulse−1. The formation of the craters was more and more distinctly observed by continuous irradiations. The number density, average diameter, and the surface coverage of the craters were not linearly dependent on the laser shot number but exhibited the saturation behavior due to the consumption of Au NPs. The threshold laser energy for the crater formation was dependent on the accumulated number of laser s.
NetO-App: A Network Orchestration Application for Centralized Network Management in Small Business Networks

Software-defined networking (SDN) is reshaping the networking paradigm. Previous research shows that SDN has advantages over traditional networks because it separates the control and data plane, leading to greater flexibility through network automation and programmability. Small business networks require flexibility, like service provider networks, to scale, deploy, and self-heal network infrastructure that comprises of cloud operating systems, virtual machines, containers, vendor networking equipment, and virtual network functions (VNFs); however, as SDN evolves in industry, there has been limited research to develop an SDN architecture to fulfill the requirements of small business networks. This research proposes a network architecture that can abstract, orchestrate, and scale configurations based on small business network requirements. Our results show that the proposed architecture provides enhanced network management and operations when combined with the network orchestration application (NetO-App) developed in this research. The NetO-App orchestrates network policies, automates configuration changes, and manages internal and external communication between the campus networking infrastructure.
Self‐ and maternal representations, relatedness patterns, and problem behavior in middle childhood

The present study investigated the association between children’s representations of their mothers’ and teachers’ reports of children’s problem behavior. The research team conducted semistructured narrative interviews with a community sample of 203 Israeli 9- to 11-year-old children. Ten months later, researchers collected teachers’ reports of children’s internalizing and externalizing problems. This study investigated whether children’s self-representation narratives and their maladaptive relatedness stances questionnaire scores mediated this association. Results indicated that children reporting benevolent representations of their mothers exhibited lower levels of problem behavior. More positive self-representations and lower levels of skewness in children’s relatedness stances to their mothers both mediated this association. This article includes a discussion of these results in light of factors contributing to maladjustment in middle childhood. Object relations and attachment theories suggest that internal representations or working models of the caregiver are related to competent adjustment by enabling the construction of a stable and positive self-perception and by molding adaptive patterns of interpersonal interaction with significant others (Greenberg & Mitchell, 1983). These interpersonal patterns of relatedness are significant predictors of adjustment outcomes in infant and adult samples (Buist, Dekovilc, Meeus, & Van-Aken, 2004; Fonagy & Target, 1997; Hamilton, 2000). Less is known, however, about these associations in school-age children, who were the focus of the present investigation. In the present study, we were interested in targeting the association between school-age children’s internal representation of mother, relatedness style to her, and maladaptive behavior. From a developmental standpoint, middle childhood is a period where children are beginning to represent objects cognitively at a more abstract level (Piaget, 1955, 1962) and their social interactions with significant others become more complex and intimate (Baldwin, Cole, & Baldwin, 1982; Baumrind, 1989). These parallel processes have a direct bearing on the quality of children’s internal model of the caregiver and their perception of their relationship with her.
Comparative Study of Benzyl and Phenyl Compounds Chemical Structure Effects on the Inhibition of Methane Production by Digested Pig Manure Methanogens

Aims: The present paper aims to study the effect of aromatic structure on the inhibition of biogas production and more specifically the comparative study of benzyl and phenyl compounds chemical structure effects on the inhibition of methane production by digested pig manure methanogens. The objective of this study was also to examine the structuretoxicity relationships of aromatic compounds to acetoclastic methanogens. Study Design: Anaerobic digestion of pig manure, anaerobic toxicity essay, comparison of benzyl and phenyl compounds structure effects on the inhibition of methane gas biosynthesis. Place and Duration of Study: Department of Chemistry, University of Kinshasa (DR Congo), between September 2011 and May 2012. Methodology: The toxicity to acetoclastic methanogenic bacteria was performed with the Research Article International Research Journal of Pure & Applied Chemistry, 3(1): 48-58, 2013 49 standard method of serum bottles; digested pig manure was utilized as inoculums and acetate as substrate. The methane gas volume produced was measured by serum bottles liquid displacement systems (Mariotte flask system). Results: The obtained results indicate exist between the chemical structure of benzyl and phenyl compounds and their inhibitory effects on biosynthesis of methane by methanogenic bacteria. According to these results, α-chlorotoluene and bromobenzene with 0.61 and 2.90 mg/l IC50 values, respectively, are the most toxic compounds, while phenol and benzyl alcohol with IC50 values of 1248.90 and 2391.37 are less toxic. Comparing the phenyl and benzyl compounds with the same substituents (Cl, Br, H, OH), their behavior was diverse. The benzyl chloride is more toxic than phenyl chloride and benzyl bromide is less toxic than phenyl bromide. Otherwise, benzyl alcohol is less toxic than phenol. A significant correlation between the toxicity of phenyl compounds and their hydrophobicity (R = 0.911). But any correlation was not found for benzyl compounds. Conclusion: The obtained results indicate that relationships exist between the chemical structure of benzyl and phenyl compounds and their inhibitory effects on the production of methane by methanogenic archaea. The behavior of phenyl and benzyl are different in inhibition of methane production by the methanogens because their chemical structures are not identic.
Inverse association between the effect of carbohydrates on blood glucose and subsequent short-term food intake in young men 1 – 3

Background: A primary mechanism by which carbohydrates are thought to regulate satiety and food intake is through their effect on blood glucose. Objectives: The objectives were to describe the effect of defined carbohydrate preloads on food intake and blood glucose and to determine the association between food intake and blood glucose. Design: Three experiments were conducted in which selected carbohydrates as 1255-kJ isovolumetric beverages were administered to young men after an overnight fast. Measurements of blood glucose and appetite were made at specified times during the next 60 min. Food intake was measured at 60 min. Results: Glucose resulted in the highest glycemic response, which was followed, in order, by the responses to polycose, sucrose, amylopectin, a fructose-glucose mixture, and amylose. The high-glycemic-index preloads (glucose, polycose, and sucrose) resulted in lower mealtime energy intake during a test meal at 1 h, but the low-glycemic-index preloads (amylose, amylopectin, and a fructose-glucose mixture) did not. An inverse relation was observed between the blood glucose concentrations in the area under the curve and the subjective appetite (r = 0.23, P < 0.05) and food intake at 60 min (r = 0.24, P < 0.05). Conclusions: Food intake and subjective appetite are inversely associated with blood glucose response in the 60 min after consumption of carbohydrates. Carbohydrates with a high glycemic index (glucose, polycose, and sucrose) suppress subjective appetite and food intake in the short term, but those with a low glycemic index (amylose and amylopectin) do not.

A petrographic history of martian meteorite ALH84001: Two shocks and an ancient age

— ALH84001 is an igneous meteorite, an orthopyroxenite of martian origin. It contains petrographic evidence of two shock metamorphic events, separated by thermal and chemical events. The evidence for two shock events suggests that ALH84001 is ancient and perhaps a sample of the martian highlands. From petrography and mineral chemistry, the history of ALH84001 must include: crystallization from magma, a first shock (impact) metamorphism, thermal metamorphism, low-temperature chemical alteration, and a second shock (impact) metamorphism. Originally, ALH84001 was igneous, an orthopyroxene-chromite cumulate. In the first shock event, the igneous rock was cut by melt-breccia or cataclastic veinlets, now bands of equigranular fine-grained pyroxene and other minerals (crush zones). Intact fragments of the cumulate were fractured and strained (now converted to polygonized zones). The subsequent thermal metamorphism (possibly related to the first shock) annealed the melt-breccia or cataclastic veinlets to their present granoblastic texture and permitted chemical homogenization of all mineral species present. The temperature of metamorphism was at least 875 °C, based on mineral thermometers. Next, Mg-Fe-Ca carbonates and pyrite replaced plagioclase in both clasts and granular bands, producing ellipsoidal carbonate globules with sub-micron scale compositional stratigraphy, repeated identically in all globules. The second shock event produced microfault offsets of carbonate stratigraphy and other mineral contacts, radial fractures around chromite and maskelynite, and strain birefringence in pyroxene. Maskelynite could not have been preserved from the first shock event, because it would have crystallized back to plagioclase. The martian source area for ALH84001 must permit this complex, multiple impact history. Very few craters on young igneous surfaces are on or near earlier impact features. It is more likely that ALH84001 was ejected from an old igneous unit (Hesperian or Noachian age), pocked by numerous impact craters over its long exposure at the martian surface.
A global model for the uptake of atmospheric hydrogen by soils

A simple process‐based model for the consumption of atmospheric hydrogen (H2) has been developed. The model includes a description of diffusion and biological processes which together control H2flux into the soil. The model was incorporated into the LPJ‐WHyMe Dynamic Global Vegetation Model, and used to simulate H2 fluxes over the 1988–2006 period. The model results have been confronted with field and laboratory measurements. The model reproduces observed seasonal cycles of H2 uptake at different sites and shows a realistic sensitivity to changes in soil temperature and soil water content in comparisons with field and laboratory measurements. A recent study, based on 3D atmospheric model inversion, found an increase of the global H2 sink from soils, with a trend of −0.77 Tg a−2 for the 1992–2004 period (fluxes are negative as soils act as a sink for atmospheric H2). For the same period, however, our process‐based model calculates a trend of only −0.04 Tg a−2. Even when forced with drastic changes in soil water content, soil temperature and snow cover depth, our model is unable to reproduce the trend found in the inversion‐based study, questioning the realism of such a large trend.
