Cellulase immobilization properties and their catalytic effect on cellulose hydrolysis in ionic liquid

Cellulase was immobilized on chitosan by the method of covalent binding. The optimum immobilized conditions were as follow: the pH value was 5.0, the glutaraldehyde concentration was 0.015 (w/v) and the formaldehyde concentration was 0.15 (w/v). Both the free and immobilized cellulase were characterized by determining the pH, temperature, thermal stability and storage stability. The optimum pH of both the free and immobilized cellulase was found as 4. The immobilized cellulase had optimum temperature of 50 degrees C as compared to 40 degrees C in case of free enzyme. The immobilized enzyme showed higher thermal stability than the free cellulase, after 120 min, the activity of immobilized cellulose and the free enzyme retained 86.5 and 61% respectively. After 11 cycles, the activity of the immobilize enzyme conserved 80.27%. The immobilized enzyme exhibited slightly better storage stability than the free enzyme. The Km and Vm values for the immobilized and free cellulase were 8.1 and 1.84 mg/L and 0.01 and 0.0036 mg/ml/min respectively. Cellulose hydrolysis by immobilized cellulase in the presence of a 88 ionic liquid (IL), 1,3-dimethylimidazolium dimethylphosphate (MMIM-DMP), was investgated. The result showed that the addition of 20% (v/v) MMIM-DMP gave the highest initial rate, which was 1.3 and 13.9 times higher than the hydrolysis rate in citric acid - sodium hydrogen phosphate buffer and in IL, respectively.
Guaranteed Equal Opportunities? The Access to Nursing Training in Central Europe for People with a Turkish Migration Background

This paper examines the reason for the small percentage of professional nurses with a Turkish migration background and investigates possibilities to increase this low amount. Our society grows older, and the number of chronic diseases increases. Furthermore, nursing professionals tend to migrate, and the retirement of the baby boomer generation will also create a lack of professional nurses in Vorarlberg, Austria. People with a Turkish migration background, who are the second largest group without Austrian citizenship in Austria, could be an important resource for the upcoming lack of qualified nurses. The nursing profession could be a secure career opportunity for these people, and therefore it is of great importance to make access to professional nursing training easier for people with a Turkish migration background. This paper describes the effects of migration on society, institutions and individuals and gives an overview of concepts related to how to deal with this situation. This qualitative study investigates the access to nursing training for people with a Turkish migration background from three different points of view—those of experts, students and nurses with a Turkish migration background, and people with a Turkish migration background who have to pass a university entrance qualification—in the form of guided interviews. The results will illustrate structural and social barriers due to complex social dynamics and also highlight possibilities to reduce those barriers. Based on the results, prospects for professional nursing are deduced on the macro, meso and micro levels, which should generate an increasing number of nurses with a Turkish migration background.
Real-time Event Detection in Twitter: A Case Study

In this paper we present the study which uses hashing as a vectorizer and locality sensitive hashing to approximately find similar items, combined with incremental clustering to implement a practical real-time event detection algorithm. By gathering a substantial amount of Persian tweets, the proposed algorithm is evaluated. It is shown that the presented pipeline and methods are capable of detecting the events related to 7 out of 10 football matches during the days in which the Iranian national football team took part in the 2018 FIFA World Cup. A total of 102 events were detected with a precision of 87.25%.
5G New Radio Evaluation Against IMT-2020 Key Performance Indicators

The fifth generation (5G) of mobile radio technologies has been defined as a new delivery model where services are tailored to specific vertical industries. 5G supports three types of services with different and heterogeneous requirements, i.e. enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communications (URLLC) and massive Machine-Type Communications (mMTC). These services are directly related to exemplary verticals such as media, vehicular communications or the Industry 4.0. This work provides a detailed analysis and performance evaluation of 5G New Radio (NR) against a set of Key Performance Indicators (KPI), as defined in the International Mobile Telecommunications 2020 (IMT-2020) guidelines, and provides an overview about the fulfillment of their associated requirements. The objective of this work is to provide an independent evaluation, complementing the Third Generation Partnership Project (3GPP) contribution. From the original group of sixteen KPIs, eleven of them have been carefully selected, paying special attention to eMBB services. Results show that 5G NR achieves all considered requirements, therefore fulfilling the specific market’s needs for years to come.
The analysis of the MspI polymorphism within exon 3 of the calpastatin gene in Slovak Simmental cattle.

Calpastatin has important function in the tenderization process. The SNP polymorphisms in the calpastatin gene suchas UoG-CAST (intron 5) and CAST-T1 (3´UTR region) are used as markers in commercial test for prediction ofanimals with tenderness meat. The others research of the calpastatine gene confirmed the impact of a SNPpolymorphism in exon 3 on fertility and longevity in dairy cattle, too. The aim of this study was to analyse thepopulation of 113 animals of Slovak Simmental (42 bulls and 71 cows) for the missense SNP polymorphism in exon3. Bovine genomic DNA was isolated from sperm and blood by commercial kit. The SNP CAST c.283 C>T wasdetected by PCR-RFLP method with restriction endonuclease MspI. The favourable allele C was detected by tworestriction fragments 135 bp and 173 bp and the allele T with the one 308 bp fragment. In the analyzed population ofSlovak Simmental cattle were detected the following frequency of alleles and genotypes for the SNP c.283 C>T ofthe CAST gene. Frequencies of allele C and allele T were 0.6460 and 0.3540 and frequencies of genotypes were0.4336 (genotype CC), 0.4248 (genotype CT) and 0.1416 (genotype TT).
Effect of Method of Adding a Fibrolytic Enzyme to Dairy Cow Diets on Feed Intake Digestibility, Milk Production, Ruminal Fermentation, and Blood Metabolites#

This study investigated the effect of the method of applying a fibrolytic enzyme (Promote®; Cargill; Minnetonka, MN) on the performance of lactating dairy cows. A diet consisting of Tifton 85 bermudagrass silage, corn silage, and concentrate (35, 10 and 55% of dietary DM respectively) was fed ad libitum as a total mixed ration (TMR) twice daily. Cows were assigned randomly to the following five treatments: 1) control (no enzyme added), enzyme applied 2) at ensiling to bermudagrass (ES), 3) at mixing to the concentrate (EC), 4) at feeding to the TMR (ETMR), or 5) the bermudagrass silage (EF). In Experiment 1, thirty Holstein cows (129 days in milk, DIM) were used in a completely randomized, cross-over design consisting of two 28-d periods, with 14 d for adaptation and 14 d for sample collection. Voluntary DMI, total tract apparent digestibility of DM, NDF and CP, milk production and component yields were not affected by enzyme supplementation. Cows fed ETMR had lower blood βhydroxybutyrate concentration, tended to have greater milk fat and protein concentrations and lower blood urea-N concentration than cows fed the control diet. In Experiment 2, five ruminally-cannulated cows were fed the same five diets for three consecutive 15-d periods to measure rumen fermentation (d 12) and in situ degradation (d 14 and 15). Compared to cows fed the control diet, ruminal pH tended to be lower in cows fed EC and ruminal NH3-N concentration was lower in cows fed the ETMR diet. The molar proportion of acetic acid was lower in cows fed ETMR and EF diets vs. the control diet. Total volatile fatty acid concentration and acetate: propionate ratio were lower in cows fed ETMR vs the control diet. Enzyme application did not affect in situ degradability except that the ES diet tended to degrade at a faster rate than the control diet. Enzyme application to the TMR gave the most desirable responses (tended to increase milk fat and protein concentrations and improved the efficiency of ruminal energy utilization and decreased ruminal protein degradation). However, enzyme addition did not affect intake, digestibility or milk yield.
Rest-activity rhythms, daytime symptoms, and functional performance among people with heart failure

ABSTRACT Sleep disturbance and decreased daytime activity are well-described among people with chronic heart failure (HF) who suffer from disabling daytime symptoms and poor function. Alterations in the circadian rhythmicity of rest-activity may also be associated with these outcomes. However, little is known about the associations between rest-activity rhythms (RARS), symptoms, and functional performance or the extent to which they are explained by sleep characteristics among people with HF. The purpose of this study is to evaluate parametric and non-parametric circadian characteristics of RARs and the associations between these variables, daytime symptoms, and functional performance among patients with stable heart failure (HF). We recruited adults with stable HF from HF disease management programs. Participants wore wrist actigraphs for 3 d, completed one night of unattended polysomnography and the Six Minute Walk Test, and reported daytime symptoms and physical function. We performed cosinor, non-parametric, and spectral analyses to evaluate the rest-activity rhythms and computed bivariate correlations between the rest-activity rhythm, demographics, daytime symptoms, and functional performance. We conducted multiple regression analysis to examine how RARs contribute to daytime symptoms and functional performance after controlling for insomnia and covariates. The sample included 135 participants [Mean age = 60.6 (16.1) y, n = 88 (65.2%) male]. Older age, greater comorbidity, and poorer New York Heart Association (NYHA) Class, and more EEG arousals were associated with greater intra-daily variability of the RAR. More robust rhythmicity represented by the circadian quotient was associated with better NYHA class and less sleep fragmentation. A higher circadian quotient was significantly associated with lower fatigue, depression, and sleepiness, and better functional performance after controlling for insomnia and clinical and demographic characteristics. Circadian parameters of rest-activity are associated with symptoms and functional performance among people with HF independent of insomnia or sleep disordered breathing. Interventions targeted at improving the stability and strength of rest-activity rhythms may improve symptom and functional outcomes for these patients.
Empowering Health Workers to Protect their Own Health: A Study of Enabling Factors and Barriers to Implementing HealthWISE in Mozambique, South Africa, and Zimbabwe

Ways to address the increasing global health workforce shortage include improving the occupational health and safety of health workers, particularly those in high-risk, low-resource settings. The World Health Organization and International Labour Organization designed HealthWISE, a quality improvement tool to help health workers identify workplace hazards to find and apply low-cost solutions. However, its implementation had never been systematically evaluated. We, therefore, studied the implementation of HealthWISE in seven hospitals in three countries: Mozambique, South Africa, and Zimbabwe. Through a multiple-case study and thematic analysis of data collected primarily from focus group discussions and questionnaires, we examined the enabling factors and barriers to the implementation of HealthWISE by applying the integrated Promoting Action on Research Implementation in Health Services (i-PARiHS) framework. Enabling factors included the willingness of workers to engage in the implementation, diverse teams that championed the process, and supportive senior leadership. Barriers included lack of clarity about how to use HealthWISE, insufficient funds, stretched human resources, older buildings, and lack of incident reporting infrastructure. Overall, successful implementation of HealthWISE required dedicated local team members who helped facilitate the process by adapting HealthWISE to the workers’ occupational health and safety (OHS) knowledge and skill levels and the cultures and needs of their hospitals, cutting across all constructs of the i-PARiHS framework.
Men, chronic illness and healthwork: accounts from male partners of women with endometriosis.

Currently dominant in medical discourse, the concept of self-management sees the responsibility for health and illness shift from the state to the individual. However, while this emphasis on individual responsibility and management has burgeoned, the role and status of partners and other family members in the management of chronic illness remains under-theorised. While self-management privileges individual responsibility for the management of chronic illness, the role of partners remains unclear. This paper utilises data from a study of heterosexual couples' experiences of living with the chronic gynaecological condition endometriosis to explore how male partners engage in its day-to-day management. In all, 22 couples participated in in-depth, semi-structured interviews with each partner interviewed separately (n = 44). Data were analysed thematically and dyadically, informed by an interpretivist relational approach. The paper utilises the concept of healthwork to describe the illness work, everyday life work, biographical work and emotion work men engaged in. The paper demonstrates how the conceptual value of healthwork is enhanced by incorporating an analysis of the emotional effort required in managing chronic illness. The paper illustrates the value of investigating the role of partners in managing chronic illness to provide a fuller account of the distributed and relational nature of healthwork.
Structure-biological activity relationship of synthetic trihydroxilated chalcones

A atividade bacteriostatica de 2,4,2-trihidroxichalcona, 2,4,3-trihidroxichalcona e 2,4,4-trihidroxichalcona, preparadas por condensacao de 2,4-dihidroxiacetofenona e benzaldeido convenientemente substituido, contra Staphylococcus aureus ATCC 25923 foi avaliada pela tecnica de difusao em placas. Importantes halos de inibicao foram observados para os tres compostos. Com o proposito de esclarecer a relacao estrutura-atividade biologica, as concentracoes inibitorias minimas (CIM) frente a S. aureus foram determinadas, empregando o metodo da diluicao em caldo. Os resultados obtidos foram semelhantes a 2,4-dihidroxichalcona, observando-se a seguinte ordem: CIM 2,4,3-(OH)3 > CIM 2,4-(OH)2 > CIM 2,4,4-(OH)3 > CIM 2,4,2-(OH). A sequencia obtida mostra que a introducao de um grupo doador de eletrons (OH) no anel aromatico B provoca um aumento da bioatividade, sendo a intensidade dependente da posicao do substituinte -OH.
Comorbid Conditions, Mental Health and Cognitive Functions in Adults with Fibromyalgia

This study examined age group differences across adulthood in comorbid conditions, mental health, and cognitive function in people with fibromyalgia. Participants completed an online survey about how fibromyalgia affects their everyday life. Chi square analyses were conducted to examine associations between age groups and (a) comorbid conditions and (b) severity of anxiety and depression. ANOVA analyses examined age group differences on aspects of self-report cognitive function. The greatest prevalence of comorbid conditions was found in middle adulthood. Early adulthood was associated with more cases of severe anxiety with the lowest number of cases being in the oldest age group. Middle adulthood was associated with worse self-report pain compared to the youngest age group. Older adults showed better self-report cognitive function compared to younger adults. Distinct age profiles based on comorbid conditions, mental health, and symptom severity across adulthood in fibromyalgia have been demonstrated.
Synergistic Evaluation of Ginger and Licorice Extracts in a Mouse Model of Colorectal Cancer

Abstract Herbal medicine can be used to overcome the side effects of conventional treatments. This study aimed to evaluate the anticancer activities of ginger and licorice extracts, as well as the synergistic effects of their combination. Ginger ethanolic extract (GEE) and licorice methanolic extract (LME) were isolated by a Soxhlet extractor. Next, the anti-proliferative activity of the extracts, apoptosis induction, tumor growth inhibition, and tumor-infiltrating T lymphocytes were investigated. The MTT (3-[4, 5-dimethylthiazol-2-yl]-2, five diphenyl tetrazolium bromide) assay showed that GEE and LME decreased the CT26 cell viability in a dose-dependent manner; however, the GEE + LME combination was more effective (P < 0.05). The CT26 cells treated with each extract showed a significant increase in Bax/Bcl-2 ratio and caspase-3 gene expression, especially in the GEE + LME group (P < 0.001). Tumor volume significantly reduced in the GEE + LME group, compared to the negative controls. Finally, mice treated with GEE + LME showed a significant increase in the CTL/Treg cell ratio (P < 0.001) and Bax/Bcl2 ratio (P < 0.05). The study results revealed that GEE + LME can suppress cancer cell growth, increase apoptosis, and improve CTL infiltrating to the tumor site in a synergetic manner in-vivo and in-vitro. Therefore, the prepared mixture can be used in future clinical trials.
Agoramétrie’s Trunk Questions & Moscovici Social Representation’s Core – More than Just Similarities

Thirty years of almost annual Agoramétrie surveys of opinions in France on social conflicts have shown the existence of a very stable two-dimensional structure with a “closure” / “openness” axis and a second “emotional” axis. These same results also show the existence of “trunk questions” which systematically appear in these surveys. On the other hand, in social representation, Serge Moscovici and his colleagues have shown through the method of “associated words”, among others, that there is a very stable “core” or “nucleus” of social representations that generates and largely determine all the others. In this article, we present these two approaches and their results, and show that the set of “trunk questions” and the “heart” of social representations are more than just similar and perhaps identical.
Comparing the estimates of effect obtained from statistical causal inference methods: An example using bovine respiratory disease in feedlot cattle

The causal effect of an exposure on an outcome of interest in an observational study cannot be estimated directly if the confounding variables are not controlled. Many approaches are available for estimating the causal effect of an exposure. In this manuscript, we demonstrate the advantages associated with using inverse probability weighting (IPW) and doubly robust estimation of the odds ratio in terms of reduced bias. IPW approach can be used to adjust for confounding variables and provide unbiased estimates of the exposure’s causal effect. For cluster-structured data, as is common in animal populations, inverse conditional probability weighting (ICPW) approach can provide a robust estimation of the causal effect. Doubly robust estimation can provide a robust method even when the specification of the model form is uncertain. In this paper, the usage of IPW, ICPW, and doubly robust approaches are illustrated with a subset of data with complete covariates from the Australian-based National Bovine Respiratory Disease Initiative as well as simulated data. We evaluate the causal effect of prior bovine viral diarrhea exposure on bovine respiratory disease in feedlot cattle. The results show that the IPW, ICPW and doubly robust approaches would provide a more accurate estimation of the exposure effect than the traditional outcome regression model, and doubly robust approaches are the most preferable overall.
Functional analysis of the OsNPF4.5 nitrate transporter reveals a conserved mycorrhizal pathway of nitrogen acquisition in plants

Significance Low availability of nitrogen (N), mainly nitrate in aerobic soils, is a primary limiting factor for crop production. Most terrestrial plants live in symbiosis with arbuscular mycorrhizal (AM) fungi to increase nutrient uptake, including N, from soil. Research on the AM symbiosis field has focused almost exclusively on ammonium as the form of N transferred to the plants, and there has been no direct evidence of N transfer as nitrate thus far. Here, we report that mycorrhizal rice could receive more than 40% of its N via the mycorrhizal pathway and that the AM-specific nitrate transporter OsNPF4.5 accounted for approximately 45% of the mycorrhizal nitrate uptake. Our work suggests the presence of a mycorrhizal route for nitrate uptake in plants. Low availability of nitrogen (N) is often a major limiting factor to crop yield in most nutrient-poor soils. Arbuscular mycorrhizal (AM) fungi are beneficial symbionts of most land plants that enhance plant nutrient uptake, particularly of phosphate. A growing number of reports point to the substantially increased N accumulation in many mycorrhizal plants; however, the contribution of AM symbiosis to plant N nutrition and the mechanisms underlying the AM-mediated N acquisition are still in the early stages of being understood. Here, we report that inoculation with AM fungus Rhizophagus irregularis remarkably promoted rice (Oryza sativa) growth and N acquisition, and about 42% of the overall N acquired by rice roots could be delivered via the symbiotic route under N-NO3− supply condition. Mycorrhizal colonization strongly induced expression of the putative nitrate transporter gene OsNPF4.5 in rice roots, and its orthologs ZmNPF4.5 in Zea mays and SbNPF4.5 in Sorghum bicolor. OsNPF4.5 is exclusively expressed in the cells containing arbuscules and displayed a low-affinity NO3− transport activity when expressed in Xenopus laevis oocytes. Moreover, knockout of OsNPF4.5 resulted in a 45% decrease in symbiotic N uptake and a significant reduction in arbuscule incidence when NO3− was supplied as an N source. Based on our results, we propose that the NPF4.5 plays a key role in mycorrhizal NO3− acquisition, a symbiotic N uptake route that might be highly conserved in gramineous species.
