A Fast UHF RFID Localization Method Using Unwrapped Phase-Position Model

A novel ultrahigh-frequency (UHF) radio frequency identification (RFID) localization method is proposed in this paper, by which the location of a static passive tag can be easily obtained using a mobile RFID antenna. An unwrapped phase-position model with three parameters is built, and the location of the tag can be pinpointed through an ordinary nonlinear least-squares algorithm. The main advantage of this method is that it is cheap in computation cost compared with the existing grid-based methods. The experimental tests confirm that the proposed method can localize the RFID tags with a competitive computational efficiency and accuracy performance, i.e., millisecond-level computing time and centimeter-level location accuracy. The proposed UHF RFID localization method is well suited to the pervasive location-aware applications, searching RFID-tagged item in the intelligent warehouse by the mobile robot with an onboard RFID system, for example. Note to Practitioners—Ultrahigh-frequency (UHF) radio frequency identification (RFID) has become an efficient booster for the warehouse logistics management due to its low cost, battery-free, and unique identification. The location-aware technology based on RFID is an enabling technology for intelligent warehouse logistics. This paper proposes a passive UHF RFID tag localization method, by which the tags can be easily localized by the use of a mobile RFID system. The experimental results show that the proposed method can localize the static tags with good performance, especially low computation cost. The proposed localization method contributes to the pervasive location-aware application, in which their computation ability is usually limited. For example, mobile robots with the RFID system autonomously seek the RFID-tagged stocks in a warehouse.
Changing Cultural Practices: A Case Study of Male Circumcision in South Africa

This article presents a case study of Simon, a 25-year old Black South African male. According to his Pedi customs, Simon underwent traditional male circumcision (TMC) as a 12-year-old adolescent. He tells of his fears relative to this experience and how, over time, he transitioned from a belief in TMC to a strong preference for medical male circumcision (MMC). Using a single-case study design, the aim of the research was to explore the value of the exercise of choice in TMC, which may influence cultural perceptions of gender and masculinity. The study unpacks the way in which the meaning and experience of TMC is shaped by the social and cultural contexts of South Africa. This qualitative exploration complements conventional medical accounts of circumcision, which are often focused on the medical procedure while ignoring cultural and social factors. Issues of gender, particularly the construction of hegemonic masculinity and how it positions men, women, and young boys in relation to each other and their communities, are discussed. Simon’s case study provides new insights and perspectives on personally and culturally sensitive issues which are not easily accessed nor commonly understood. Data collected via in-depth interviews were transcribed and analyzed thematically. Analysis applied information from the literature and key concepts from the theoretical standpoint of social constructivism. Case study analysis allowed space for unexpected, emergent themes to arise from the data. Four main themes were identified, notably language, silence, patriarchy, and masculinity.
Participant characteristics and self-reported weight status in a cross-sectional pilot survey of self-identified followers of popular diets: Adhering to Dietary Approaches for Personal Taste (ADAPT) Feasibility Survey

Abstract Objective: To describe characteristics of self-identified popular diet followers and compare mean BMI across these diets, stratified by time following diet. Design: Cross-sectional, web-based survey administered in 2015. Setting: Non-localised, international survey. Participants: Self-selected followers of popular diets (n 9019) were recruited to the survey via social media and email announcements by diet community leaders, categorised into eight major diet groups. Results: General linear models were used to compare mean BMI among (1) short-term (<1 year) and long-term (≥1 year) followers within diet groups and (2) those identifying as ‘try to eat healthy’ (TTEH) to all other diet groups, stratified by time following the specific diet. Participants were 82 % female, 93 % White and 96 % non-Hispanic. Geometric mean BMI was lower (P < 0·05 for all) among longer-term followers (≥1 year) of whole food, plant-based (WFPB), vegan, whole food and low-carb diets compared with shorter-term followers. Among those following their diet for 1–5 years (n 4067), geometric mean BMI (kg/m2) were lower (P < 0·05 for all) for all groups compared with TTEH (26·4 kg/m2): WFPB (23·2 kg/m2), vegan (23·5 kg/m2), Paleo (24·6 kg/m2), vegetarian (25·0 kg/m2), whole food (24·6 kg/m2), Weston A. Price (23·5 kg/m2) and low-carb (24·7 kg/m2). Conclusion: Our findings suggest that BMI is lower among individuals who made active decisions to adhere to a specific diet, particularly more plant-based diets and/or diets limiting highly processed foods, compared with those who simply TTEH. BMI is also lower among individuals who follow intentional eating plans for longer time periods.
NAD‐specific glutamate dehydrogenase from Thermus thermophilus HB8: purification and enzymatic properties

An NAD-specific glutamate dehydrogenase from Thermus thermophilus HB8 was purified 350-fold by a several-step procedure involving Blue-Sepharose chromatography. The native protein had a molecular mass of approximately 289 kDa, and consisted of six subunits with a molecular mass of 48 kDa each. The optimum pH for the deaminating reaction was 8.0. The optimum temperature was around 85–90°C. NAD-glutamate dehydrogenase showed a high coenzyme specificity, catalysed preferentially glutamate catabolism and presented Km values for NAD and l-glutamate of 0.27±0.03 mM and 49±10 mM, respectively. No activity was detected with NADH or NADPH, 2-oxoglutarate and ammonia. Enzyme activity was found to be very stable at 72°C. Differential scanning calorimetry revealed a tm of 95°C for denaturation.

Evaluation of the teaching recovery techniques community-based intervention for accompanied refugee children experiencing post-traumatic stress symptoms (Accompanied refugeeS In Sweden Trial; ASsIST): study protocol for a cluster randomised controlled trial

Background Refugee children have often experienced traumas and are at significant risk of developing mental health problems, such as symptoms of post-traumatic stress disorder (PTSD), depression and anxiety, which can continue for years after resettlement. The Accompanied refugeeS In Sweden Trial (ASsIST) aims to evaluate a community-based intervention, called ‘Teaching Recovery Techniques’ (TRT), for accompanied refugee minors experiencing PTSD symptoms. Methods/design A cluster randomised controlled trial will be conducted in which participants will be randomly allocated to one of the two possible arms: the intervention arm (n=113) will be offered the TRT programme and the waitlist-control arm (n=113) will receive services as usual, followed by the TRT programme around 20 weeks later. Outcome data will be collected at three points: pre-intervention (T1), post-intervention (T2; c.8 weeks after randomisation) and follow-up (T3; c.20 weeks after randomisation). Ethics and dissemination Ethical approval was granted by the Regional Ethical Review Board in Uppsala (Ref. 2018/382) (24th February 2019). Results will be published in scientific journals. Trial registration details ISRCTN17754931. Prospectively registered on 4th June 2019.
Structure and function of the juxtamembrane GAF domain of potassium biosensor KdpD

KdpD/KdpE two‐component signaling system regulates expression of a high affinity potassium transporter responsible for potassium homeostasis. The C‐terminal module of KdpD consists of a GAF domain linked to a histidine kinase domain. Whereas certain GAF domains act as regulators by binding cyclic nucleotides, the role of the juxtamembrane GAF domain in KdpD is unknown. We report the high‐resolution crystal structure of KdpD GAF domain (KdpDG) consisting of five α‐helices, four β‐sheets and two large loops. KdpDG forms a symmetry‐related dimer, wherein parallelly arranged monomers contribute to a four‐helix bundle at the dimer‐interface, SAXS analysis of KdpD C‐terminal module reveals an elongated structure that is a dimer in solution. Substitution of conserved residues with various residues that disrupt the dimer interface produce a range of effects on gene expression demonstrating the importance of the interface in inactive to active transitions during signaling. Comparison of ligand binding site of the classic cyclic nucleotide‐binding GAF domains to KdpDG reveals structural differences arising from naturally occurring substitutions in primary sequence of KdpDG that modifies the canonical NKFDE sequence motif required for cyclic nucleotide binding. Together these results suggest a structural role for KdpDG in dimerization and transmission of signal to the kinase domain.
Comparison Between Clopidogrel and Prasugrel Associated With CYP2C19 Genotypes in Patients Receiving Percutaneous Coronary Intervention in a Japanese Population.

BACKGROUND The association between cytochrome P450 (CYP) 2C19 genotypes and adverse events in patients treated with clopidogrel or prasugrel after percutaneous coronary intervention (PCI) in the Japanese population is unclear.Methods and Results:This study consisted of 1,580 patients whoseCYP2C19genotypes were assessed at Shiga University of Medical Science Hospital, and 193 clopidogrel-treated and 217 prasugrel-treated patients who were followed more than 1 year after receiving PCI were analyzed. Among 1,580 patients, the prevalence of normal, intermediate, and poor metabolizers was 32%, 49%, and 17%, respectively. Overall incidence of the primary outcome, defined as a composite of cardiovascular death, myocardial infarction, definite stent thrombosis, ischemic stroke, or major bleeding was not significantly different between the clopidogrel and prasugrel groups (adjusted hazard ratio [HR] 1.98, 95% confidence interval [CI] 0.85-4.61, P=0.12). Among patients with theCYP2C19loss-of-function (LOF) allele, however, the incidence of the primary outcome was significantly higher in the clopidogrel group (adjusted HR 3.19, 95% CI 1.10-9.24, P=0.03), whereas no difference was observed among patients without theCYP2C19LOF allele (adjusted HR 0.67, 95% CI 0.14-3.26, P=0.62). CONCLUSIONS Among patients with theCYP2C19LOF allele, the use of clopidogrel was significantly associated with increased adverse events. Thus, further investigation is needed to establish the practical use ofCYP2C19genotyping.
Economic hardship and child intake of foods high in saturated fats and added sugars: the mediating role of parenting stress among high-risk families

Abstract Objective: Economic hardship (EH) may link to poorer child diet, however whether this association is due to resource limitations or effects on family functioning is unknown. This study examines whether parenting stress mediates the association between EH and child consumption of foods high in saturated fats and added sugars (SFAS). Design: Data were collected from the Fragile Families and Child Wellbeing study. EH was assessed using eight items collected when children were between 1–9 years old. Mothers reported parenting stress and frequency of child consumption of high SFAS foods when children were 9 years old. Latent growth curve modelling (LGCM) and structural equation modelling tested direct associations between the starting level/rate of change in EH and high SFAS food consumption, and parenting stress as a mediator of the association. Setting: Twenty US cities. Participants: Mothers/children (n 3846) followed birth through age 9 years, oversampled ‘high-risk’, unmarried mothers. Results: LGCM indicated a curvilinear trend in EH from ages 1–9, with steeper increases from ages 3–9 years. EH did not directly predict the frequency of high SFAS foods. Average EH at 3 and 5 years and change in EH from ages 1–9 predicted higher parenting stress, which in turn predicted more frequent consumption of high SFAS foods. Conclusions: Findings suggest it may be important to consider parenting stress in early prevention efforts given potential lasting effects of early life EH on child consumption of high SFAS foods. Future research should explore how supports and resources may buffer effects of EH-related stress on parents and children.

Holistic assessment of the microbiome dynamics in the substrates used for commercial champignon (Agaricus bisporus) cultivation

Microorganisms strongly influence and are required to generate the selective substrate that provides nutrients and support for fungal growth, and ultimately to induce mushroom fructification under controlled environmental conditions. In this work, the fungal and bacterial microbiota living in the different substrates employed in a commercial crop (compost phase I, II and III, flush 1 and 2, and casing material on day 1, 6 and 8 after compost casing and during flush 1 and 2) have been characterized along the different stages of cultivation by metataxonomic analysis (16S rRNA and ITS2), analysis of phospholipid fatty acid content (PLFAs) and RT‐qPCR. Additionally, laccase activity and the content of lignin and complex carbohydrates in compost and casing have been quantified. The bacterial diversity in compost and casing increased throughout the crop cycle boosted by the connection of both substrates. As reflected by the PLFAs, the total living bacterial biomass appears to be negatively correlated with the mycelium of the crop. Agaricus bisporus was the dominant fungal species in colonized substrates, displacing the pre‐eminent Ascomycota, accompanied by a sustained increase in laccase activity, which is considered to be a major product of protein synthesis during the mycelial growth of champignon. From phase II onwards, the metabolic machinery of the fungal crop degrades lignin and carbohydrates in compost, while these components are hardly degraded in casing, which reflects the minor role of the casing for nourishing the crop. The techniques employed in this study provide a holistic and detailed characterization of the changing microbial composition in commercial champignon substrates. The knowledge generated will contribute to improve compost formulations (selection of base materials) and accelerate compost production, for instance, through biotechnological interventions in the form of tailored biostimulants and to design environmentally sustainable bio‐based casing materials.
Phonological false recognition, recollection, and familiarity in healthy aging and Alzheimer's disease.

BACKGROUND Thirty healthy older people, 20 Alzheimer's disease patients (matched on age and education level) and 33 young people, participated in an experiment to implicitly induce phonological false memories, allowing us to obtain estimates of their recollection, familiarity, and false recognition. METHOD In the study task, words were selected which used half of the letters in the alphabet. In the recognition test, there were three types of non-studied new words: critical lures using letters from the same half of the alphabet as the study task words; distractors formed using the unused half of the alphabet, and distractors formed using all the letters in the alphabet. RESULTS Results showed that: (a) in all the samples, critical lures produced more false recognitions than distractors composed of all the letters in the alphabet or distractors composed of the letters not used in the study, showing a significant phonological false recognition effect; (b) both recollection and familiarity declined with age and dementia; (c) phonological false recognition increased with age and Alzheimer's disease. CONCLUSIONS These results seem to support the idea that estimates of recollection, familiarity, and phonological false recognition can be used as early markers of cognitive impairment.
Magnetic Nanoparticles Based Solid Phase Extraction Methods for the Determination of Trace Elements

Abstract The past three decades has seen significant advancements in instrumental detection techniques for both organic and inorganic analytes, leading to more accurate and precise measurements. The relevance of sample preparation prior to instrumental reading cannot be underestimated, and this area has also seen major improvements, with solid phase extraction (SPE) and its miniaturized version (solid phase microextraction, SPME) serving as an efficient clean-up and preconcentration method for analytes. Magnetic nanoparticles (MNPs) belong to the new generation of sorbents, and their characteristic small size and easy manipulation under magnetic field make them ideal materials for extraction of several analytes. This review presents the basic principles of SPE and SPME, and lays more emphasis on different types of MNPs that have been used as efficient separation and preconcentration tools. In addition, application of MNPs for the determination of trace elements in environmental, biological and food samples are well documented in this review.
Glucagon-like peptide-1 response to whey protein is less diminished by dipeptidyl peptidase-4 in comparison with responses to dextrin, a lipid and casein in rats

Abstract Although glucose is the best-known nutrient to stimulate glucagon-like peptide-1 (GLP-1) secretion, dietary peptides also potently stimulate GLP-1 secretion. Certain peptide fragments derived from dietary proteins possess dipeptidyl peptidase-4 (DPP-4) inhibitory activity in vitro. Hence, we hypothesised that dietary peptides protect GLP-1 from degradation through attenuating DPP-4 activity in vivo. Here, we compared GLP-1 responses with dietary proteins, a carbohydrate and a lipid (Intralipos) in rats having or not having plasma DPP-4 activity. Plasma GLP-1 concentrations clearly increased by oral administration of whey protein (2–4 g/kg), but not by that of dextrin (2–4 g/kg), in control rats (untreated Sprague–Dawley rats and F344/Jcl rats), having DPP-4 activity. In contrast, dextrin administration increased the plasma GLP-1 concentrations as the whey protein administration did, in rats having reduced or no DPP-4 activity (a DPP-4 inhibitor, sitagliptin-treated Sprague–Dawley rats or DPP-4-deficient F344/DuCrl/Crlj rats). DPP-4 inhibition by sitagliptin treatment also enhanced GLP-1 response to Intralipos, and casein, but the treatment did not further enhance GLP-1 response to whey protein. Intestinal GLP-1 content and gastric emptying rate were not associated with differences in GLP-1 responses to test nutrients. The luminal contents from rats administered whey protein decreased DPP-4 activity in vitro. These results suggest that GLP-1 released by dextrin, Intralipos and casein was immediately degraded by DPP-4, while GLP-1 released by whey protein was less degraded. Our study provides novel in vivo evidence supporting the hypothesis that dietary peptides not only stimulate GLP-1 secretion but also inhibit DPP-4 activity to potentiate GLP-1 response.
Effects of Polymethylmethacrylate Cement Viscosity and Bone Porosity on Cement Leakage and New Vertebral Fractures After Percutaneous Vertebroplasty: A Prospective Study

Study Design: A prospective randomized study. Objectives: To evaluate the effect of bone cement viscosity as well as of bone porosity on cement leakage during vertebroplasty and to analyze the occurrence of new vertebral fractures after the procedure. Methods: Between April 2012 and December 2013, 60 patients suffering from osteoporotic vertebral fractures underwent vertebroplasty. The patients were randomly assigned into 2 equal groups. High-viscosity cement was used in group A, while low-viscosity cement was used in group B. Patients were followed-up for a minimum of 2 years. Results: Cement leakage occurred in 16 patients in group B (20 vertebral bodies) and in 6 patients in group A (9 vertebral bodies). The difference was statistically significant (χ2 = 2.3, P = .01). Lower T-scores were associated with significantly more cement leakage (t = 3.338, P = .002 in group A, and t = 4.329, P = .000 in group B). Patients with a T-score worse than −1.8 had a significantly higher risk of cement leakage if low-viscosity cement was used (χ2 = 3.25, P = .05). New vertebral fractures occurred in 14 (23%) patients, after a mean of 6.5 ± 5.5 months, 10 patients in group A and 4 in group B. The difference did not reach the statistical significance level (χ2 = 3.354, P = .067). Patients presenting with multiple fractures had a significantly more number of new vertebral fractures (χ2 = 7.464, P = .006). Conclusions: The clinical outcome of vertebroplasty was not influenced by cement viscosity. However, lower cement viscosity and higher degree of osteoporosis were found to be significant risk factors for cement leakage. Furthermore, the number of vertebral body fractures on presentation was a predictor for the occurrence of new fractures postoperatively.
Geographic variation in the PRNP gene and its promoter, and their relationship to chronic wasting disease in North American deer

ABSTRACT PRNP genotypes, number of octarepeats (PHGGGWGQ) and indels in the PRNP promoter can influence the progression of prion disease in mammals. We found no relationship between presence of promoter indels in white-tailed deer and mule deer from Nebraska and CWD presence. White-tailed deer with the 95 H allele and G20D mule deer were more likely to be CWD-free, but unlike other studies white-tailed deer with the 96S allele(s) were equally likely to be CWD-free. We provide the first information on PRNP genotypes and indels in the promoter for Key deer (all homozygous 96SS) and Coues deer (lacked 95 H and 96S alleles, but possessed a uniquely high frequency of 103 T). All deer surveyed were homozygous for three tandem octarepeats.
