No Statistic Correlation between Superoxide Dismutase and Peroxidase Activities and Aluminum-Induced Lipid Peroxidation in Maize, Implying Limited Roles of Both Enzymes in Prevention against Aluminum-Induced Lipid Peroxidation

Changes of and correlation among root tolerance index (RTI), root Aluminum (Al) content, root/shoot ratio (RSR), root malondialdehyde (MDA) content, and Superoxide dismutase (SOD) and peroxidase (POD) isoforms of maize YQ 7-96 were investigated under Al stress and removal of the stress (RS). Consequently, Al stress led to significant decreases in RTI, RSR, SOD and POD activities, but resulted in significant increase in root MD A and, Al accumulation in the tissues; Root SOD and POD activities did not correlate with Al and MDA contents in roots; The activities of SOD and POD were much lower in roots than in leaves. It can be concluded that (1) Al stress can lead to lipid peroxidation; (2) there is a larger POD family composed of different POD isoforms, some of which are of tissue-specific expression and play different roles in detoxification of Al in maize; (3) for POD isoforms, POD 2 is root-specific. POD 6 and POD 7 are all leaf-specific, POD 5 is not only root-specific but also RS-responsive; (4) high sensitivity of maize to Al is in part associated with much lower activities of both SOD and POD in roots; and (5) more importantly, both SOD and POD are therefore hinted to be not key players in prevention against Al-induced lipid peroxidation.
Short-term clinical results of Nobel Direct implants: a retrospective multicentre analysis.

PURPOSE The present retrospective clinical study was undertaken to evaluate the survival rate and marginal bone conditions around Nobel Direct one-piece implants. The purpose was also to compare the results with when these implants are used for immediate/early loading with implants allowed to heal before loading. MATERIAL AND METHODS Forty-three consecutive patients previously treated with 117 Nobel Direct implants at four different centres were evaluated. The implants had been used in both jaws for treatment after loss of single and multiple teeth. Immediate/early loading (within 2 weeks) with a provisional crown/bridge was applied to 95 implants, while 22 implants healed unloaded for 6 weeks to 6 months before loading. Calculations of marginal bone loss were performed in radiographs taken at placement and after an average of 10.2 months (range 1-18 months) of loading. RESULTS Six (5.1%) of the 117 implants were removed during the follow up. All failed implants belonged to the immediate/early loading group giving a failure rate of 6.3% for this group and 0% for two-stage implants. The failure rate was higher for flapless (7.9%) than for flap surgery (0%). The marginal bone loss was -2.4 mm (SD 1.5) for all implants, while 37.6% showed more than 3 mm of loss during the follow up. Bone loss increased with time of follow up. Implants subjected to immediate/early loading showed more bone loss than two-stage implants: -2.6 mm (SD 1.5) vs. -1.6 mm (SD 1.1). Moreover, 41.3% of immediately loaded and 22.7% of two-stage implants presented with more than 3 mm of bone loss. CONCLUSIONS This short-term retrospective analysis showed a poor clinical outcome of Nobel Direct implants. Extensive marginal bone loss (>3 mm) was found around more than 1/3 of the implants evaluated. Less resorption and no failures were experienced when implants were allowed to heal from 6 weeks to 6 months before occlusal loading. Within the limitations of the present study design, data indicate that immediate loading, the use of this implant for multi-unit constructions and flapless surgery are risk factors for failure of Nobel Direct implants.
Parenting styles, feeding styles and food-related parenting practices in relation to toddlers’ eating styles: A cluster-analytic approach

Introduction Toddlers’ eating behaviors are influenced by the way parents interact with their children. The objective of this study was to explore how five major constructs of general parenting behavior cluster in parents of toddlers. These parenting clusters were further explored to see how they differed in the use of feeding strategies (i.e. feeding styles and food parenting practices) and by reported child eating styles. Methods An online survey with 1005 mothers/caregivers (legal guardians) with at least one child between 12 and 36 months old was conducted in the United States in 2012, assessing general parenting behavior, feeding style, food parenting practices and the child eating styles. Results A three cluster solution of parenting style was found and clusters were labelled as overprotective/supervising, authoritarian, and authoritative. The clusters differed in terms of general parenting behaviors. Both overprotective and authoritative clusters showed high scores on structure, behavioral control, and nurturance. The overprotective cluster scored high on overprotection. The ‘authoritarian’ cluster showed lowest levels of nurturance, structure and behavioral control. Overprotective and authoritative parents showed very similar patterns in the use of food parenting practices, e.g. monitoring food intake, modeling, and promoting healthy food intake and availability at home. Overprotective parents also reported higher use of pressure to eat and involvement. Authoritarian parents reported high use of giving the child control over their food behaviors, emotion regulation, using food as a reward, and controlling food intake for weight control. Children’s eating styles did not largely vary by parenting cluster. Conclusion This study showed that a relatively new parenting style of overprotection is relevant for children’s eating behaviors. Overprotective parents reported food parenting practices that are known to be beneficial for children’s food intake, such as modelling healthy food intake, as well as more unfavorable practices such as pressure. Longitudinal data on parenting practices and their relation to healthy eating in children is needed to inform communication and interventions for parents, reinforcing key feeding strategies which have positive effects on child eating behaviors and addressing parenting styles that have unintended negative effects.
FRP RODS WITH PIEZOELECTRIC TRANSDUCERS FOR DAMAGE DETECTION

FRP materials open the door to new types of sensors for civil infrastructure. In this work FRP rods with imbedded piezoelectric transducers are used to detect damage in concrete. The detection of damage specifically cracking in civil structures is of great interest for SHM. Small (mm sized) piezoelectric transducers can be used to detect damage in several different modes, but are challenging to effectively mechanically couple to civil structures. In this work piezoelectric transducers were embedded into FRP rods to enhance the mechanical coupling. The sensors were tested by embedding them in concrete test cylinders and then sense the effects of controlled damage. The sensors are operated with a pair of transducers, where one acts excite and the other acts to sense mechanical response. The effects of damage could be clearly observed in plots of response versus frequency. Damage tended to increase the number of mechanical modes that could be observed.
Susceptibility to Salmonella typhimurium Infection and Effectiveness of Vaccination in Mice Deficient in the Tumor Necrosis Factor Alpha p55 Receptor

ABSTRACT Mice defective in the ability to produce the tumor necrosis factor alpha p55 receptor (TNFαp55R) were orally challenged with a number ofSalmonella typhimurium HWSH derivatives that differ in virulence. In comparison to TNFαp55R+/+ mice, TNFαp55R−/− mice succumbed earlier to challenge with wild-type S. typhimurium HWSH and S. typhimurium HWSH purE. In contrast, TNFαp55R−/− mice were able to control anS. typhimurium HWSH aroA challenge, although greater numbers of Salmonella organisms were present in the tissues for a longer time period than was observed with TNFαp55R+/+ mice. Vaccination of normal and TNFαp55R knockout animals with S. typhimurium HWSH aroA showed that TNFαp55R−/− mice, unlike TNFαp55R+/+ mice, were not protected against a virulent S. typhimurium HWSH challenge. Splenocytes from TNFαp55R−/− mice exhibited a reduced ability to proliferate in the presence of S. typhimuriumantigen compared to TNFαp55R+/+ mice. Thus, TNFαp55R is essential for controlling Salmonellagrowth in tissues and for recall of immunity in murine salmonellosis.
Cloning and characterization of the genes for two distinct cephalosporin acylases from a Pseudomonas strain

Pseudomonas sp. strain SE83 converts cephalosporin C and 7 beta-(4-carboxybutanamido)cephalosporanic acid (GL-7ACA) to 7-aminocephalosporanic acid (7ACA). A DNA library of this strain was constructed in Escherichia coli and screened for the ability to deacylate GL-7ACA to 7ACA. Apparently, two distinct genes, designated acyI and acyII, were cloned on 4.8- and 6.0-kilobase-pair BglII fragments, respectively. The enzymes encoded by the two genes showed different substrate specificities, and the acyII-encoded enzyme was found to yield 7ACA from cephalosporin C by direct deacylation. Expression of the two genes in E. coli was strongly dependent on a promoter of the vector. The coding regions for acyI and acyII were localized on the 2.5- and 2.8-kilobase-pair fragments, respectively, by subcloning experiments, and high expression of both genes was obtained by placing them under the control of the lacUV5 promoter. The acyII-encoded enzyme was purified and shown to be composed of two nonidentical subunits with molecular weights of 26,000 and 57,000. Maxicell analysis revealed three acyII-specific polypeptides, two of which corresponded to the above subunits. The third polypeptide with a molecular weight of 83,000 was suggested to be the precursor of both subunits.
HERITABILITY AND NON GENETIC FACTORS FOR LIFETIME PRODUCTION TRAITS IN NEW ZEALAND WHITE RABBITS RAISED IN INTENSIVE SYSTEM OF PRODUCTION

Data on 14210 litters of New Zealand White rabbits produced by 2945 does mothered by 1613 dams and fathered by 842 sires were analysed to characterize this breed for lifetime production traits and to estimate variance components and heritabilities of these traits. Lifetime production traits measured per doe were total number born (TNB), total number born alive (TNBA), total number weaned (TNW), number of litters produced by the doe (NL) and length of lifetime production (LT). The mean performances of lifetime production traits per doe were 39.2, 42.0 and 31.2 bunnies for TNBA, TNB and TNW, respectively. LT was 8.1 month and NL was 4.8 litters. Litter size in which the doe was born constituted a highly significant (P<0.001) source of variation in TNBA, TNB and TNW. The heritabilities (h2) for these traits were low and ranged from 0.05 to 0.13. Heritabilities estimated were reliable and precised since standard errors for heritabilities were low and ranged from 0.003 to 0.076.
Dynamic interactions of biofilms of mucoid Pseudomonas aeruginosa with tobramycin and piperacillin

The dynamic interaction of planktonic and biofilm cells of mucoid Pseudomonas aeruginosa with tobramycin and piperacillin was investigated in a chemostat system. The results indicated that planktonic and young biofilm cells of the 2-day-old chemostat culture of P. aeruginosa were susceptible to killing by chemostat-controlled doses of either 250 micrograms of piperacillin per ml plus 5 micrograms of tobramycin per ml or 500 micrograms of piperacillin per ml plus 5 micrograms of tobramycin per ml. Complete eradication of the planktonic and young biofilm cells was observed after exposure of the cells to six chemostat-controlled doses of these antibiotic at 8-h intervals for 7 days. Regrowth of the organism was not observed after the termination of antibiotic therapy on day 7. A different picture was observed when antibiotic treatment was initiated on day 10 after inoculation. Viable old biofilm cells were reduced to approximately 20% after exposure to the chemostat-controlled doses of 500 micrograms of piperacillin per ml plus 5 micrograms of tobramycin per ml. Complete eradication of old biofilm cells could not be achieved, and regrowth of the organism occurred after the termination of antibiotic therapy. These data suggest that young biofilm cells of mucoid P. aeruginosa can be effectively eradicated with the combination of piperacillin and tobramycin, while old biofilm cells are very resistant to these antibiotics and eradication of old biofilm cells is not achievable with the chemostat-controlled doses of piperacillin and tobramycin used in this study.
Consonantal and vocalic gestures in the articulation of the Italian glides /j/ and /w/ at different syllable positions

From a phonological point of view, four glides (or approximants) exist in Italian: /j/, /w/, [i̯] and [u̯]. Glides still raise a lot of questions, from the definition of the necessary and sufficient features for their identification (Chitoran, Nevins, 2008), to their characterization at the acoustic and articulatory levels of speech production (Gick, 2003). In this paper, in order to describe the articulatory features of Italian glides, we analyzed the kinematics of both consonantal and vocalic gestures involved in the production of /j/ and /w/, by using 3D electromagnetic articulography (EMA; Carstens Medizinelektronik GmbH). The results show similar articulatory features for both glides in the way they differentiate themselves from corresponding vowels [i] and [u].
Study of histomorphological patterns of ovarian tumors

Introduction: Ovarian tumors have various histomorphological patterns. Histopathological examination plays an important role is classifying ovarian tumors for better prognosis. Ovarian tumors are classified into surface epithelial tumors, germ tumors and sex cord stromal tumors. This study was done to know various histomorphological patterns of ovarian tumors. Materials and Methods: Both retrospective and prospective study done from March 2013 to April 2015 for 2 yrs in the department of pathology, Kakatiya Medical College Warangal and private histopathological laboratories. On microscopy histomorphological patterns of ovarian tumors were noted. Sections were given and slides were stained with H & E. Special stains like reticulin, PAS, mucicarmine were done where ever necessary. Results: 154 ovarian tumors were studied, 78.5% (121/154) were benign and 21.4% (33/154) were malignant. Surface epithelial tumors were most common (61.6%), followed by germ cell tumors (29.8%). Sex cord stromal tumors comprised only 4.5 % (7/154) of all ovarian tumors. Metastatic tumors of ovaries were far less common than primary ovarian tumors. They comprised only 3.8 % (6/154) of all ovarian tumors. Age ranged from 15-65 with majority of cases were reported among 35- 45yrs 81 (52.5%). The youngest patient of our series was a girl of 16 yrs with dysgerminoma and the oldest patient was a 65 yrs, a case of mucinous cystadenocarcinoma ovary. Conclusion: Surface epithelial tumors were most common followed by germ cell tumors. Majority of tumors were reported amongage group 35- 45yrs. Metastatic tumors of ovaries were less common.
Comprehensive framework for internet banking adoption: an empirical analysis in the Indian context

The study presents an integrated framework to analyse factors influencing consumer's acceptance of online banking services and tests its validity in the Indian context. The framework draws from two basic models most widely used in literature namely the technology acceptance model TAM and the technology readiness TR model. The results validate the basic TAM hypothesis that the intention to use internet banking is predicted by the two factors of perceived usefulness and perceived ease of using online banking technology. Age, gender and TR profiles moderate the relationship between the two factors and the behavioural intention to use internet banking. Trust in the bank was found to be another key factor driving a customer's intention. Knowledge of the customer demographics and TR profiles and how they influence his acceptance of internet banking can enable banks to understand their customers better and design tailor made marketing efforts towards activation.
Identification of metabolic fluxes in hepatic cells from transient 13C‐labeling experiments: Part II. Flux estimation

This contribution addresses the identification of metabolic fluxes and metabolite concentrations in mammalian cells from transient 13C‐labeling experiments. Whilst part I describes experimental set‐up and acquisition of required metabolite and 13C‐labeling data, part II focuses on setting up network models and the estimation of intracellular fluxes. Metabolic fluxes were determined in glycolysis, pentose‐phosphate pathway (PPP), and citric acid cycle (TCA) in a hepatoma cell line grown in aerobic batch cultures. In glycolytic and PPP metabolite pools isotopic stationarity was observed within 30 min, whereas in the TCA cycle the labeling redistribution did not reach isotopic steady state even within 180 min. In silico labeling dynamics were in accordance with in vivo 13C‐labeling data. Split ratio between glycolysis and PPP was 57%:43%; intracellular glucose concentration was estimated at 101.6 nmol per 106 cells. In contrast to isotopic stationary 13C‐flux analysis, transient 13C‐flux analysis can also be applied to industrially relevant mammalian cell fed‐batch and batch cultures. Biotechnol.

Antiviral medications for preventing cytomegalovirus disease in solid organ transplant recipients.

BACKGROUND The risk of cytomegalovirus (CMV) infection in solid organ transplant recipients has resulted in the frequent use of prophylaxis with the aim of preventing the clinical syndrome associated with CMV infection. OBJECTIVES To determine the benefits and harms of antiviral medications to prevent CMV disease and all-cause mortality in solid organ transplant recipients. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, reference lists and abstracts from conference proceedings without language restriction. SELECTION CRITERIA Randomised and quasi-randomised controlled trials comparing antiviral medications with placebo or no treatment, trials comparing different antiviral medications and trials comparing different regimens of the same antiviral medications in recipients of any solid organ transplant. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed trial quality and extracted data from each trial. Statistical analyses were performed using the random effects model and results expressed as relative risk (RR) for dichotomous outcomes with 95% confidence intervals (CI). Subgroup analysis and univariate meta-regression were performed using restricted maximum-likelihood to estimate the between study variance. Multivariate meta-regression was performed to investigate whether the results were altered after allowing for differences in drugs used, organ transplanted and recipient CMV serostatus at the time of transplantation. MAIN RESULTS Thirty two trials (3737 participants) were identified. Prophylaxis with aciclovir, ganciclovir or valaciclovir compared with placebo or no treatment significantly reduced the risk for CMV disease (19 trials; RR 0.42, 95% CI 0.34 to 0.52), CMV infection (17 trials; RR 0.61, 95% CI 0.48 to 0.77), and all-cause mortality (17 trials; RR 0.63, 95% CI 0.43 to 0.92) primarily due to reduced mortality from CMV disease (seven trials; RR 0.26, 95% CI 0.08 to 0.78). Prophylaxis reduced the risk of herpes simplex and herpes zoster disease, bacterial and protozoal infections but not fungal infection, acute rejection or graft loss. Meta-regression showed no significant difference in the risk of CMV disease or all-cause mortality by organ transplanted or CMV serostatus; no conclusions were possible for CMV negative recipients of negative organs. In direct comparison trials, ganciclovir was more effective than aciclovir in preventing CMV disease (seven trials; RR 0.37, 95% Cl 0.23 to 0.60). Valganciclovir and intravenous ganciclovir were as effective as oral ganciclovir. AUTHORS' CONCLUSIONS Prophylaxis with antiviral medications reduces CMV disease and CMV-associated mortality in solid organ transplant recipients. They should be used routinely in CMV positive recipients and in CMV negative recipients of CMV positive organ transplants.
Canvassing the Filipino Trans Man’s Story: A Narrative Analysis of Transgender Men’s Youtube Video Blogs

This exploratory study strives to understand the stories of Filipino transgender men through the lens of narrative psychology. By listening to the narratives of trans men, I explored how their gender and male identity is reconstructed and negotiated within Filipino society. The Youtube video blogs of five Filipino trans men were analyzed using narrative analysis. Nine key events were found and organized under the pre-transition, the transition, and the post-transition timeline. The nine events revolved around the following themes: (1) realization of identity, (2) coping with gender dysphoria, (3) coming out, (4) decision to transition, (5) undergoing hormone therapy, (6) engaging with the trans community, (7) facing social/institutional challenges, (8) balancing between stealth or coming out, and (9) finding the road to advocacy and resolution. Overall, the findings specified social and psychological challenges that compel trans men to create their own gendered narratives.
Microstructure , mechanical properties and wear behaviour of Zn − Al − Cu − TiB 2 in situ composites

Zn−Al−Cu−TiB2 (ZA27−TiB2) in situ composites were fabricated via reactions between molten aluminum and mixed halide salts (K2TiF6 and KBF4) at temperature of 875 °C. The microstructure, mechanical properties and wear behavior of the composites were investigated. Microstructure analysis shows that fine and clean TiB2 particles distribute uniformly through the matrix. The mechanical properties of the composites increase with the increase in TiB2 content. As TiB2 content increases to 5% (mass fraction), an improvement of HB 18 in hardness and 49 MPa in ultimate tensile strength (UTS) is achieved. The overall results reveal that the composites possess low friction coefficients and the wear rate is reduced from 5.9×10 to 1.3×10 mm/m after incorporating 5% TiB2. Friction coefficient and worn surface analysis indicate that there is a change in the wear mechanism in the initial stage of wear test after introducing in situ TiB2 particles into the matrix.
Code Reuse in Open Source Software Development: Quantitative Evidence, Drivers, and Impediments

The focus of existing open source software (OSS) research has been on how and why individuals and firms add to the commons of public OSS code - that is, on the “giving” side of this open innovation process. In contrast, research on the corresponding “receiving” side of the innovation process is scarce. We address this gap, studying how existing OSS code is reused and serves as an input to further OSS development. Our findings are based on a survey with 686 responses from OSS developers. As the most interesting results, our multivariate analyses of developers’ code reuse behavior point out that developers with larger personal networks within the OSS community and those who have experience in a greater number of OSS projects reuse more, presumably because both network size and a broad project experience facilitate local search for reusable artifacts. Moreover, we find that a development paradigm that calls for releasing an initial functioning version of the software early - as the “credible promise” in OSS - leads to increased reuse. Finally, we identify developers’ interest to tackle difficult technical challenges as detrimental to efficient reuse-based innovation. Beyond OSS, we discuss the relevance of our findings for companies developing software and for the receiving side of open innovation processes in general.
