A Polygenic Risk Score as a Risk Factor for Medication‐Associated Fractures

Some commonly prescribed drugs are associated with increased risk of osteoporotic fractures. However, fracture risk stratification using skeletal measures is not often performed to identify those at risk before these medications are prescribed. We tested whether a genomically predicted skeletal measure, speed of sound (gSOS) from heel ultrasound, which was developed in 341,449 individuals from UK Biobank and tested in a separate subset consisting of 80,027 individuals, is an independent risk factor for fracture in users of fracture‐related drugs (FRDs). To do this, we first assessed 80,014 UK Biobank participants (including 12,678 FRD users) for incident major osteoporotic fracture (MOF, n = 1189) and incident hip fracture (n = 209). Effects of gSOS on incident fracture were adjusted for baseline clinical fracture risk factors. We found that each standard deviation decrease in gSOS increased the adjusted odds of MOF by 42% (95% confidence interval [CI] 1.34–1.51, p < 2 × 10−16) and of hip fracture by 31% (95% CI 1.15–1.50, p = 9 × 10−5). gSOS below versus above the mean increased the adjusted odds of MOF by 79% (95% CI 1.58–2.01, p < 2 × 10−16) and of hip fracture by 42% (95% CI 1.08–1.88, p = 1.3 × 10−2). Among FRD users, each standard deviation decrease in gSOS increased the adjusted odds of MOF by 29% (nMOF = 256, 95% CI 1.14–1.46, p = 7 × 10−5) and of hip fracture by 30% (nhip fracture = 68, 95% CI 1.02–1.65, p = 0.0335). FRD users with gSOS below versus above the mean had a 54% increased adjusted odds of MOF (95% 1.19–1.99, p = 8.95 × 10−4) and a twofold increased adjusted odds of hip fracture (95% 1.19–3.31, p = 8.5 × 10−3). We therefore showed that genomically predicted heel SOS is independently associated with incident fracture among FRD users. © 2020 American Society for Bone and Mineral Research.
Quantitative analysis of the local rates of growth of dicot leaves at a high temporal and spatial resolution, using image sequence analysis

Summary A new technique is presented for quantitative mapping of dicot leaf growth at high spatial and temporal resolution, at a speed making online-mapping feasible. Time lapse video sequences of growing leaves are captured by a personal computer (PC) with a frame-grabber board and a standard CCD camera, and evaluated using algorithms that have been recently developed to analyse motion in dynamic image sequences. Growth can be detected at under 1% per hour, with a time resolution of minutes and a spatial resolution of a few millimeters. The new technique has been verified by comparing it with classical approaches to map integrated growth. Diurnal courses of leaf growth ofRicinus communisand tobacco are presented to demonstrate the localised character of growth in leaves. Expansion growth is restricted to the base of the leaf and is restricted to a few hours at the end of the night and the start of the day. The high resolution of the method is illustrated by mapping the responses to step-changes in leaf turgor. A 3 bar turgor jump led to a rapid transient expansion over the entire length of the leaf that was partially reversed when the turgor was relaxed.
MODEL-BASED TEST CASE PRIORITIZATION: A SYSTEMATIC LITERATURE REVIEW

Re-testing all test cases during regression testing is costly and time-consuming. These problems motivate researchers to come up with various techniques to overcome them. One of the techniques is Test Case Prioritization that prioritizes test cases in test suite by ordering them according to a desired objective goal. Model-based is one of the approaches which utilizes the system models to make prioritization. The main purpose of this systematic review is to identify and categorize the current state-of-the-art while providing a baseline for future research in model-based Test Case Prioritization. A general search term related to model-based approach was used during the study search in selected digital libraries ranging from 2005 to 2016 to find primary studies that propose model-based approach. A total of 32 primary studies consisting of 21 combinations of conference proceedings, workshop, and symposium and 12 journal articles were finalized after going through a strict selection process. A sum of 48 distinct approaches with their respective characteristics and models used have been identified, and some general constraints of model-based Test Case Prioritization have been highlighted. Future research is recommended to put more focus in detailing the introduced category to benefit the researchers and practitioners.
Space-Time Surveillance of Negative Emotions after Consecutive Terrorist Attacks in London

Terrorist attacks pose significant threats to mental health. There is dearth information about the impact of consecutive terrorist attacks on space-time concentrations of emotional reactions. This study collected (1) Twitter data following the two terrorist attacks in London in March and June of 2017, respectively, and (2) deprivation data at small areal levels in the United Kingdom. The space-time permutation model was used to detect the significant clusters of negative emotions, including fear, sadness, and anger in tweets. Logistic regression models were used to examine the social deprivation of communities associated with negative tweeting. The results reported two significant clusters after the March attack, one was in London, ten days after the attack, and the other was far from the attack site between Manchester and Birmingham, three days after the attack. Attention to the reoccurring attack in June diminished quickly. The socially deprived communities experienced double disadvantage—sending fewer tweets but expressing more negative emotions than their counterparts. The findings suggest that terrorism can affect public emotions far and broad. There is a potential for surveillance to rapidly identify geographically concentrated emotions after consecutive or prolonged disasters using social media data.
Exploring Consumers’ Purchase Intention of an Innovation of the Agri-Food Industry: A Case of Artificial Meat

Green consumption is an emerging environmental topic receiving global attention. Because livestock production is a primary source of greenhouse gas emission, the “low-carbon diet” has become a new trend in the catering industry. Fast food companies have been launching vegetarian products because artificial meat requires less water and land resources than traditional livestock and has lower carbon emissions. This study explores the influence of consumers’ attitude, subjective norms (SNs), and perceived behavioral control (PBC) on their purchase intention for vegetarian burgers from the product knowledge (PK) and environmental concern (EC) perspectives. Based on the theory of planned behavior, the purchase intention of people from different food cultures to pay for fast food burgers is discussed. Five hundred questionnaires were distributed, of which 436 were valid. The results revealed that: (1) consumers’ SNs, PBC, and EC significantly affect purchase intention (PI), and SNs and PK have no significant relationship with PI; and (2) vegetarians are willing to pay higher prices than nonvegetarians. This study recommends that industry personnel should attempt to increase consumers’ knowledge regarding artificial meat and expand marketing channels to improve the convenience of purchasing artificial meat foods by conducting lectures and media promotion, respectively.
Fatty Acid Composition of Fry Mirror Carp (Cyprinus carpio) Fed Graded Levels of Sand Smelt (Atherina boyeri) Meal

The effect of replacement of fish meal (FM) in diets with sand smelt meal (SSM) on fatty acid composition of carp fry, Cyprinus carpio, was examined. Five isonitrogenous and isoenergetic (38% crude protein, ) diets replacing 0, 25, 50, 75, and 100% FM protein by SSM protein were formulated. Each diet was randomly allocated to triplicate groups of fish in aquaria, and each aquarium was stocked with 20 fish (initial average weight of ). Fish were fed twice daily to apparent satiation for 13 weeks. Results indicated that final weight, specific growth rate and feed efficiency ratio of fish fed with different SSM replacement diets did not differ significantly (p>0.05) from fish fed the control diet, except for 100% SSM level. No significant differences were noted among experimental treatments on dry matter, protein, lipid and ash contents of the fish body composition (p>0.05). Fatty acid analysis showed that saturated fatty acids in fish muscle significantly decreased, but monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) did not change with increasing dietary SSM. However, some changes also could be observed for some particular fatty acids in experimental fish. For example, the amounts of 15:0, 17:0, 18:1n-7, 18:2n-6 and 22:5n-3 significantly increased, but 16:0, 18:1n-9, 18:3n-3 and 20:1 n-9 significantly decreased with increasing dietary SSM. Total n-6 PUFA increased with increasing dietary SSM, but total n-3 PUFA were not changed in muscle of fish fed the experimental diets. The ratio of n-3 to n-6 was not affected significantly in muscle of fish fed the experimental diets containing different proportions of SSM, including the control diet.
Effectiveness of Home Bleaching Treatment after Resin Infiltrant Application.

PURPOSE Resin infiltration may be a barrier for bleaching gels. The aim of this study was to compare dental bleaching effectiveness using low-concentration gels on heavily or mildly stained teeth that were or were not treated with resin infiltration agents. MATERIALS AND METHODS Forty bovine enamel surfaces were submitted to demineralisation, after which two staining protocols were performed. Twenty specimens were immersed in a staining broth for 24 h (Lab 1) or 7 days (Lab 2). Ten specimens of each group received resin infiltrant application following the manufacturer's recommendation. All specimens were bleached using 15% carbamide peroxide gel for 14 days (8 h daily). Colour measurement was performed using a reflectance spectrophotometer at three time points: baseline, after staining, and after bleaching. Data (CIEDE00) were analysed using Student's t-test (p < 0.05). RESULTS No statistically significant differences were observed in Lab 1 (p = 0.560). For Lab 2, statistically significant differences were detected (p = 0.031). Once bleaching was achieved to some degree (Lab 2), the resin infiltrant may have behaved as a semipermeable barrier to the carbamide peroxide gels. CONCLUSION Bleaching treatment was effective on mildly pigmented tooth surfaces. On the other hand, in comparison to the control group, the heavily pigmented surfaces bleached less in the presence of the resin infiltrant, possibly due to the lack of free radicals penetrating into the substrate.
Topoisomerase I-driven repair of UV-induced damage in NER-deficient cells

Significance NER removes helix-destabilizing bulky adducts including UV lesions and crosslinks generated by formaldehyde. NER protects skin cells from carcinogenesis. XP patients deficient in NER develop progressive neurological dysfunction. We discovered that collaboration between TOP1 and the BER pathway can substitute for the lack of NER. This previously unappreciated repair pathway is initiated by TOP1-dependent sensing topological alterations near UV lesions and subsequent SSB formation followed by BER. Considering that the SSB formation by TOP1 is the rate-limiting step, and TOP1 expression is very low in the skin and neuronal tissues, our finding may help understand the molecular mechanisms and genetic determinants underlying the neurological dysfunction of XP patients, although TOP1-relevant endogenous lesions are currently unknown. Nucleotide excision repair (NER) removes helix-destabilizing adducts including ultraviolet (UV) lesions, cyclobutane pyrimidine dimers (CPDs), and pyrimidine (6–4) pyrimidone photoproducts (6–4PPs). In comparison with CPDs, 6–4PPs have greater cytotoxicity and more strongly destabilizing properties of the DNA helix. It is generally believed that NER is the only DNA repair pathway that removes the UV lesions as evidenced by the previous data since no repair of UV lesions was detected in NER-deficient skin fibroblasts. Topoisomerase I (TOP1) constantly creates transient single-strand breaks (SSBs) releasing the torsional stress in genomic duplex DNA. Stalled TOP1-SSB complexes can form near DNA lesions including abasic sites and ribonucleotides embedded in chromosomal DNA. Here we show that base excision repair (BER) increases cellular tolerance to UV independently of NER in cancer cells. UV lesions irreversibly trap stable TOP1-SSB complexes near the UV damage in NER-deficient cells, and the resulting SSBs activate BER. Biochemical experiments show that 6–4PPs efficiently induce stable TOP1-SSB complexes, and the long-patch repair synthesis of BER removes 6–4PPs downstream of the SSB. Furthermore, NER-deficient cancer cell lines remove 6–4PPs within 24 h, but not CPDs, and the removal correlates with TOP1 expression. NER-deficient skin fibroblasts weakly express TOP1 and show no detectable repair of 6–4PPs. Remarkably, the ectopic expression of TOP1 in these fibroblasts led them to completely repair 6–4PPs within 24 h. In conclusion, we reveal a DNA repair pathway initiated by TOP1, which significantly contributes to cellular tolerance to UV-induced lesions particularly in malignant cancer cells overexpressing TOP1.
Gender Differences in the Levels of Periodontal Destruction, Behavioral Risk Factors and Systemic Oxidative Stress in Ischemic Stroke Patients: A Cohort Pilot Study

Background: Due to the higher frequency of ischemic stroke in men compared to women, we aimed to determine if gender differences exist regarding periodontal status and several plasma biomarkers in patients with a recent large artery atherosclerosis ischemic stroke (IS). Material and methods: Patients with their first IS within less than six weeks who were able to undergo periodontal examinations were evaluated. Demographic data, periodontal status, oxidative stress parameters/plasma antioxidant capacity, and C-reactive protein in patients who suffered a recent large artery atherosclerosis ischemic stroke were reccorded. Results: 93 patients were included in the study. More men were smokers (12/57 vs. 3/36) and consumed alcohol (17/57 vs. 3/36), and more women had higher glycemic values (p = 0.023), total cholesterol (p < 0.001), LDL (low-density lipoprotein)-cholesterol (p = 0.010), and HDL (high-density lipoprotein)-cholesterol (p = 0.005) levels. Significantly more men than women had moderate plus severe periodontal disease (p = 0.018), significantly higher levels of nitric oxide (p = 0.034), and significantly lower levels of total antioxidant capacity (p = 0.028). Conclusions: In this pilot study, men seem to be more prone to oxidative stress and to develop more severe forms of periodontitis among patients with stroke, but the results need validation on a larger sample.
In vitro Seed Germination of Coscinium fenestratum (Gaertn.) Colebr

The present investigation was aimed to study the In vitro seed germination potential of Coscinium fenestratum An endangered woody climber with high medicinal value to ensure germplasm conservation and mass production of planting material to meet the unlimited demand. Mature seeds of C. fenestratum can be successfully surface sterilized by dipping explants in 0.1% Mercuric Chloride (HgCl2) solution (w/v) for 2 min followed by 2 successive washings using sterilized distilled water. After surface sterilization, hard seed coats have to be damaged to overcome mechanical seed dormancy. After that seeds should be soaked 24h in filter sterilized 2,250 mg/L Gibberelic Acid (GA3) solution to break the physiological dormancy. When mature seeds stored at 4oC for 36 months, in sealed cellophane after wrapping with wet cotton; soften the hard seed coats make it easy for mechanical damaging. The experiments were repeated in two fruiting seasons (September 2011 and June 2012). Seeds have to be cultured into MS salt fortified sterilized sand: coir dust (1:1) incorporated culture vessels. To minimize fungal contaminations; 0.7g/L systemic fungicide Thiophanate methyl 70% WP (w/v) has to be introduced into culture medium. To facilitate in vitro germination, seeds should be exposed to total darkness and temperature should be increased to 32±2oC inside an incubator. Fresh seeds treated with 2,250mg/L GA3 for 24 h before culture initiation achieved 80% mean In vitro germination rate within 9 months Original Research Article Annual Research & Review in Biology, 4(23): 3549-3565, 2014 3550 of culture period. After 3 months of storage, to achieve 76% mean In vitro germination rate within a month seeds need to be exposed 24 hour to 2,250mg/L GA3. If they soaked 24h in sterilized distilled water, it was needed 4 months time to gain same result. Over 90% seedlings were successfully acclimatized and introduced to field conditions.
The mcr-9 Gene of Salmonella and Escherichia coli Is Not Associated with Colistin Resistance in the United States

Reports of transmissible colistin resistance show the importance of comprehensive colistin resistance surveillance. Recently, a new allele of the mobile colistin resistance (mcr) gene family designated mcr-9, which shows variation in genetic context and colistin susceptibility, was reported. We tested over 100 Salmonella enterica and Escherichia coli isolates with mcr-9 from the National Antimicrobial Resistance Monitoring System (NARMS) in the United States for their susceptibility to colistin and found that every isolate was susceptible, with an MIC of ≤1 μg/ml. ABSTRACT Reports of transmissible colistin resistance show the importance of comprehensive colistin resistance surveillance. Recently, a new allele of the mobile colistin resistance (mcr) gene family designated mcr-9, which shows variation in genetic context and colistin susceptibility, was reported. We tested over 100 Salmonella enterica and Escherichia coli isolates with mcr-9 from the National Antimicrobial Resistance Monitoring System (NARMS) in the United States for their susceptibility to colistin and found that every isolate was susceptible, with an MIC of ≤1 μg/ml. Long-read sequencing of 12 isolates revealed mcr-9 on IncHI plasmids that were either independent or integrated into the chromosome. Overall, these results demonstrate that caution is necessary when determining the clinical relevance of new resistance genes.
Oral capsulized Fecal microbiota transplantation for eradication of carbapenemase-producing Enterobacteriaceae colonization with a metagenomic perspective.

BACKGROUND Carbapenemase-producing Enterobacteriaceae (CPE) infections lead to considerable morbidity and mortality. We assessed the potential of fecal microbiota transplantation (FMT) to eradicate CPE carriage and aimed to explain failure or success through microbiome analyses. METHODS In this prospective cohort study, all consenting eligible CPE carriers were treated with oral capsulized FMT for 2 days. The primary outcome was CPE eradication at 1 month, defined by 3 consecutive negative rectal swabs, the last also negative for carbapenemase gene by PCR. Comprehensive metagenomics analysis of the intestinal microbiome of donors and recipients before and after FMT was performed. RESULTS Fifteen CPE carriers received FMT, 13 of which completed 2 days of treatment. CPE eradication at 1 month was successful in 9/15 and 9/13, respectively. Bacterial communities showed significant changes in both beta and alpha diversity metrics among participants achieving CPE eradication that were not observed among failures. Post-FMT samples' beta-diversity clustered according to the treatment outcome, both in taxonomy and in function. We observed a significant decrease in beta diversity in participants who received post-FMT antibiotics. Enterobacteriaceae abundance decreased in post-FMT samples of the responders, but increased among failures. Functionally, a clear demarcation between responders (who were similar to the donors) and failures was shown, driven by antimicrobial resistance genes. CONCLUSION Our study provides the biological explanation for the effect of FMT against CPE carriage. Decolonization of CPE by FMT is likely mediated by compositional and functional shifts in the microbiome. Thus, FMT might be an efficient strategy for sustained CPE eradication.
Feeding biology of the Greyheaded Parrot, Poicephalus fuscicollis suahelicus (Reichenow), in Northern Province, South Africa

Abstract The Greyheaded Parrot, Poicephalus fuscicollis suahelicus, feeds on at least 25 tree species through its range. In Northern Province, South Africa, it was recorded feeding on the fruit of six tree species during the non-breeding season (August-December) and eight species during the breeding season (April-August). It was also recorded feeding on the bark of three additional species during the breeding season. Competition with other avian frugivores was low as Greyheaded Parrots were specialist feeders, accessing the kernel of unripe fruit, which other species are unable to do. Energy content of food species ranged from 15.72 MJ kg−1 (Gmelina arborea, an exotic) to 31.18 MJ kg−1 (Sclerocarya birrea), and protein from 8.75% (G. arborea) to 39.81% (Melia azaderach, an exotic). Feeding choice reflected seasonal fruit availability, and during any one month feeding occurred on few tree species.
Sex-Based Differences in Tensiomyography as Assessed in the Lower Erector Spinae of Healthy Participants: An Observational Study

Background: Although there is mounting evidence on sex-linked differences in paraspinal muscle function, it is unknown whether sex-based variations in mechanical and contractile characteristics of the lumbar erector spinae (LES) can be monitored noninvasively in healthy participants at rest using tensiomyography (TMG). Hypothesis: Sex-specific effects in muscle displacement (Dm) and velocity of muscle deformation (Vd) will be observed via TMG assessed in the LES. Study Design: Observational study. Level of Evidence: Level 3. Methods: LES response was measured in a relaxed state in 40 healthy adults (20 females). Possible differences between the conditions were investigated using mixed-model analyses of variance. Two-stage hierarchical linear regression analyses were performed to predict the outcome of TMG Dm and Vd based on participant sex. Results: There were significant main effects of sex with large effect sizes for both TMG parameters, resulting from lower mean values in women compared with men (Dm, P < 0.01; Vd, P < 0.01). In contrast, neither the main effect of side (left vs right LES) nor the interaction between the side and sex reached significance (all P > 0.3). Introducing the sex variable in stage 2 of the regression analyses significantly improved the prediction of the TMG parameters (all ∆R2 ≥ 0.18; all P < 0.01; all f2 ≥ 0.29). Conclusion: Sex-based differences in muscle stiffness and contractile characteristics could be observed by TMG on LES muscles in healthy individuals at rest. The data suggest that these disparities are not exclusively attributable to anthropometric measures but may be linked to intrinsic sex-based differences in skeletal muscle characteristics. Clinical Relevance: We recommend implementing TMG in a clinical setting using the obtained results as a basis to factor for the patient’s biological sex when assessing effects of therapeutic/exercise regimens aiming at the optimization of myofascial tissue regeneration and performance.
