Dosimetric studies involving in the experiments for the evaluation of the brain activation by LTE exposure

This paper presented the dosimetric studies in the research for evaluating the relationship between the LTE exposure and the brain regional activation. Measurement was made for the net power delivered to the dipoles for each exposed volunteer. During the exposure experiment, the exposed power was strictly controlled to achieve a constant exposure dose for each person. The numerical head model of each volunteer was reconstructed basing on the MRI images. FDTD simulation was performed to calculate the realistic power distribution in different head regions for all the exposed volunteers. Effects with the existence of the EEG electrode and leads on the head during the exposure were taken into considered in term of local SAR and regional induced current to prevent abnormal results. The dosimetric results were therefore applied for LTE EMF exposure related brain activation research.
Factor V Leiden mutation and pregnancy-related venous thromboembolism: What is the exact risk?

Summary The magnitude of the association of factor V Leiden mutation with pregnancy-related venous thrombosis remains unclear. Our objective was to undertake a systematic review and a meta-analysis of the literature to estimate precisely the association of factor V Leiden mutation with the risk of first,or recurrent,pregnancy-related venous thromboembolism. Studies published before October 2005 were identified by Medline®. Using both fixed and random effect models, odds ratios (OR) with accompanying 95% confidential intervals (CI) were calculated for the factor V Leiden mutation and the clinical end-point (Yusuf-Peto adaptation of the Mantel-Haenszel, DerSimonian and Laird method). We identified 13 studies including 7 cohorts and 6 case control studies relating to factor V Leiden and pregnancy-related venous thrombosis.The results from the cohorts showe a pooled OR of 4.46 (95% CI,1.82–10.94;7,879 pooled women), with no evidence of statistical heterogeneity (p=0.36), for the risk of a first venous thromboembolism during pregnancy or the postpartum period associated with the factor V Leiden mutation.Case-control studies revealed a higher risk ( OR 8.6,95% CI, 5.85–12.63; 1,524 pooled women) with significant heterogeneity (p<0.005). Because of insufficient data, an analysis for the risk of recurrence could not be performed. Our findings emphasize the fact that limited data are available on this topic.This meta-analysis provides clinicians with an estimate of the average risk of a first thrombosis occurring during pregnancy in women carrying the factor V Leiden to assist the management of such women.

Chitotriosidase in Patients with Acute Ischemic Stroke

Background: Following an acute brain ischemia, local endothelia allow monocyte chemoattraction into the lesion site which contributes to brain damage through a group of neurotoxic factors. A relationship exists between the extent of brain damage and the plasma level of monocyte products, including chitotriosidase, though usually strictly related to preexisting infectious-inflammatory diseases. Purpose: Since chitotriosidase activity is also elevated in pathogen-free conditions, we tested whether chitotriosidase upregulation might be specifically related to stroke and unrelated to clinically relevant infectious diseases. Methods: We studied the plasma level of chitotriosidase activity, TNF-α and IL-6 in 44 consecutive patients with acute brain ischemia without concomitant symptoms or signs of inflammatory-infectious diseases. Results were compared with stroke severity and outcome as detected by brain CT and NIH scale. Blood samples were collected, on average, 11 h after stroke onset. Results: Chitotriosidase activity positively correlates with stroke severity, as measured by NIH scale (r = 0.69, p<0.01), to the extent of brain damage as documented by CT (r = 0.75, p ≤ 0.001) and the TNF-α level (r = 0.76, p<0.001); it also inversely correlates with the IL-6 level (r = –0.43, p ≤ 0.05). Conclusion: Our results indicate that chitotriosidase is a specific marker of macrophage activation occurring in stroke which directly correlates with stroke severity independently of preexisting inflammatory or infectious conditions.
Molecular biology of prostate-cancer pathogenesis

Purpose of review The genetic and molecular basis of prostate-cancer pathogenesis is reviewed. Recent findings Several genetic loci have been found that are associated with hereditary predisposition to prostate cancer, but they account for a small fraction of all cases. A number of suppressor genes have been identified that are activated by either complete or partial genetic loss in sporadic prostate cancer. Chromosomal translocation results in transcriptional activation of truncated ETS transcription factors ERG and ETV1, the first candidates for dominant oncogenes for prostate cancer. Lastly, the androgen receptor is active throughout the course of prostate cancer and, in androgen-independent prostate cancer, takes on the role of a dominant oncogene as the target of gene amplification, overexpression, and the activation of mutations. Summary Genetic lesions responsible for familial and sporadic prostate cancer are being revealed and they suggest that prostate cancer often initiates owing to an increased susceptibility to oxidative damage; it then progresses by affecting transcription factors, the PI3 kinase pathway, and other growth stimulatory pathways. The final common pathway after androgen ablation appears to be activation of androgen receptor.
Smart RFIC: Millimeter-wave gigabit transceivers with digitally-enabled built-in self-calibration and auto-switching functions: The challenge of phase control modeling in phase shifter design

This paper reviews recent digitally calibration and I\Q mismatch compensation techniques. The phase control modeling of phase shifter or modulator design is the most challenging task in high-speed communications. All these built-in self-calibration and auto-switching functions are innovated to pave the road to the next-generation millimeter-wave 5G mobile smart RFIC.
Caligus tenuifurcatus Wilson, 1937 (Copepoda, Siphonostomatoida), a parasite of centropomid and lutjanid teleosts from a coastal system of the Mexican Pacific

Specimens of the parasitic siphonostomatoid copepod Caligus tenuifurcatus Wilson, 1937 were collected from the oral cavity of the yellowfin snook, Centropomus robalito Jordan et Gilbert; the white snook, C. viridis Lockington (Perciformes, Centropomidae), and the yellow snapper, Lutjanus argentiventris (Peters) (Perciformes, Lutjanidae), from a Pacific coastal system of Mexico. Infection was most intense on C. viridis. Caligus tenuifurcatus can be distinguished from its closest congener, C. bonito Wilson, by the body proportions and the basal ornamentation of the medial setae of the second exopodal segment of leg 1. Taxonomic illustrations are provided of both female and male. This is the third record of C. tenuifurcatus; hitherto, it was known only as a parasite of the roosterfish Nematistius pectoralis Gill (Perciformes, Nematistiidae) from Panama and the Gulf of California. Hence, the finding of C. tenuifurcatus as a parasite of two species of centropomids and one species of lutjanid represents a significant expansion of the known host range of this copepod in the eastern tropical Pacific.
Cost and availability of gluten-free food in the UK: in store and online

Objective Coeliac disease (CD) is a lifelong condition requiring strict adherence to a gluten-free (GF) diet and good availability of GF foods is critical to this. Patients with CD from lower socioeconomic groups are recognised to have higher treatment burden and higher food costs may impact this. Therefore, we aimed to assess the availability and cost of GF food in supermarkets and via the internet. Design Supermarkets and internet shops delivering to homes in a single city (UK) were analysed between February and March 2014. Stores were identified with comprehensive internet searches. Ten commonly purchased items were analysed for cost and compared with standard non-GF alternatives. Direct measurement of the number of GF foods available was compared between stores which were categorised according to previously published work. Setting Supermarkets covering the whole of Sheffield, UK. Results None of the budget supermarkets surveyed stocked any GF foods. Quality and regular supermarkets stocked the greatest range, each stocking a median of 22 (IQR 39) items (p<0.0001). All GF foods were at least four times more expensive than non-GF alternatives (p<0.0001). GF products are prevalent online, but 5/10 of the surveyed products were significantly more expensive than equivalents in supermarkets. Conclusions There is good availability of GF food in regular and quality supermarkets as well as online, but it remains significantly more expensive. Budget supermarkets which tend to be frequented by patients from lower socioeconomic classes stocked no GF foods. This poor availability and added cost is likely to impact on adherence in deprived groups.
RECOVERY OF LITTLE BROWN BATS (MYOTIS LUCIFUGUS) FROM NATURAL INFECTION WITH GEOMYCES DESTRUCTANS, WHITE-NOSE SYNDROME

Geomyces destructans produces the white fungal growth on the muzzle and the tacky white discoloration on wings and ears that characterize white-nose syndrome (WNS) in cave-hibernating bats. To test the hypothesis that postemergent WNS-infected bats recover from infection with G. destructans, 30 little brown bats (Myotis lucifugus) were collected in May 2009 from a WNS-affected hibernation site in New Jersey. All bats were confirmed to be infected with G. destructans using a noninvasive fungal tape method to identify the conidia of G. destructans and polymerase chain reaction (PCR). The bats were then held in captivity and given supportive care for 70 days. Of the 26 bats that survived and were humanely killed after 70 days, 25 showed significant improvement in the external appearance of wing membranes, had no microscopic evidence of infection by G. destructans, and had wing tissue samples that were negative for G. destructans by PCR. A subset of the bats was treated topically at the beginning of the rehabilitation study with a dilute vinegar solution, but treatment with vinegar provided no added advantage to recovery. Provision of supportive care to homeothermic bats was sufficient for full recovery from WNS. One bat at day 70 still had both gross pathology and microscopic evidence of WNS in wing membranes and was PCR-positive for G. destructans. Dense aggregates of neutrophils surrounded the hyphae that remained in the wing membrane of this bat.
Variability in time reproduction: difference in ADHD combined and inattentive subtypes.

OBJECTIVE To examine the relationship between time reproduction, performance variability, and sustained attention deficits in children with attention-deficit/hyperactivity disorder (ADHD) combined (ADHD-C) and inattentive (ADHD-I) subtypes, relative to matched controls. METHOD Participants (age range 7.1-14.1 years) performed a time reproduction task. A subset of the ADHD group was also tested on the Sustained Attention to Response Test. Absolute discrepancy, accuracy coefficient, and intraindividual variability scores on the time reproduction task were compared across the three groups (ADHD-C: N = 20; ADHD-I: N = 19; controls: N = 44) and correlated with the Sustained Attention to Response Test. RESULTS First, significantly better performance was observed in matched controls than in children with ADHD on the time reproduction task. Second, there was a significant difference between the two ADHD subtypes in the variability of the size of errors made at high time intervals (36-60 seconds). Third, intraindividual performance variability in the direction (over- versus underestimations) of time reproductions correlated with sustained attention performance. CONCLUSIONS Children with ADHD varied more in the size and direction of their time reproduction errors than control children. Those with ADHD-C demonstrated more intraindividual variability than did those with ADHD-I in the size of their errors. The data provide support for a relationship between sustained attention and time reproduction. This relationship has previously been inferred from common right-lateralized neural circuitry that is thought to subserve these processes.
The Effect of Web Accessibility and Usability on User Preference and Search Engine Ranking

With the increase need of using the Internet in most domains, and the increasing number of users whom use it, the need of accessible and usable sites also increased for both users with or without disabilities. Also, due to the high competitive rivalry between search engines in ranking results and disparity of ranking techniques, webmasters should know about search engine guidelines related to them. In this paper we evaluated accessibility, usability, and search issues for the most 10 popular web sites in three different Arab countries (Egypt, Saudi Arabia, and Jordan). A total of 30 websites evaluated using Sort Site tool, to find the effect of web accessibility and usability on user preference and search engine ranking. The results showed that there is a strong relationship between these issues. Therefore, webmasters should apply: accessibility, usability, and webmaster search guidelines.
VgrG-5 Is a Burkholderia Type VI Secretion System-Exported Protein Required for Multinucleated Giant Cell Formation and Virulence

ABSTRACT The type VI secretion system (T6SS) has emerged as a critical virulence factor for the group of closely related Burkholderia spp. that includes Burkholderia pseudomallei, B. mallei, and B. thailandensis. While the genomes of these bacteria, referred to as the Bptm group, appear to encode several T6SSs, we and others have shown that one of these, type VI secretion system 5 (T6SS-5), is required for virulence in mammalian infection models. Despite its pivotal role in the pathogenesis of the Bptm group, the effector repertoire of T6SS-5 has remained elusive. Here we used quantitative mass spectrometry to compare the secretome of wild-type B. thailandensis to that of a mutant harboring a nonfunctional T6SS-5. This analysis identified VgrG-5 as a novel secreted protein whose export depends on T6SS-5 function. Bioinformatics analysis revealed that VgrG-5 is a specialized VgrG protein that harbors a C-terminal domain (CTD) conserved among Bptm group species. We found that a vgrG-5 ΔCTD mutant is avirulent in mice and is unable to stimulate the fusion of host cells, a hallmark of the Bptm group previously shown to require T6SS-5 function. The singularity of VgrG-5 as a detected T6SS-5 substrate, taken together with the essentiality of its CTD for virulence, suggests that the protein is critical for the effector activity of T6SS-5. Intriguingly, we show that unlike the bacterial-cell-targeting T6SSs characterized so far, T6SS-5 localizes to the bacterial cell pole. We propose a model whereby the CTD of VgrG-5—, propelled by T6SS-5—, plays a key role in inducing membrane fusion, either by the recruitment of other factors or by direct participation.
Ocular surface changes and discomfort in patients with meibomian gland dysfunction.

OBJECTIVE To determine the importance of meibomian gland dysfunction (MGD) on the ocular surface. DESIGN Prospective study. SETTING A university-based referral practice. PATIENTS Patients with ocular discomfort (147 eyes) and without ocular discomfort (54 eyes) were examined. In the total 201 eyes, MGD was defined as the presence of an obstruction of the meibomian orifices (obstruction group [n = 54]) or the absence of a gland structure (gland dropout group [n = 36]), or both of these findings (combined group [n = 38]). There were not any findings of MGD in 73 eyes (non-MGD group). MAIN OUTCOME MEASURES Scores that were obtained from fluorescein and rose bengal staining, the breakup time of the tear film, the rates of tear evaporation and tear production, and meibography. RESULTS Of the 147 eyes with ocular discomfort, 95 (64.6%) had either an obstruction of an orifice or gland dropout, or both. The combined group had higher scores for staining with fluorescein (P = .002) and rose bengal (P = .021) compared with that in the non-MGD group. The rate of tear production was increased more in the gland dropout group than in the non-MGD group (P = .002). The rate of tear evaporation was significantly increased in the gland dropout group (P = .017). CONCLUSION Meibomian gland dysfunction is a major cause of ocular surface abnormalities and ocular discomfort.
Full-Dose Aprotinin Use in Coronary Artery Bypass Graft Surgery: An Analysis of Perioperative Pharmacotherapy and Patient Outcomes

BACKGROUND: Inappropriate activation of hemostasis and inflammation may contribute to postoperative morbidity and mortality. The serine protease inhibitor, aprotinin, has been shown to prevent tissue and organ injury in laboratory and animal studies. In this retrospective analysis, we evaluated the relationship of aprotinin therapy with organ dysfunction in humans undergoing coronary artery bypass graft surgery (CABG). METHODS: Data from prospective randomized, double-blind, placebo-controlled studies evaluating the safety and efficacy of full-dose aprotinin (2 million KIU load, 2 million KIU pump prime, and 0.5 million KIU/h continuous infusion) to reduce blood loss and transfusion requirements in patients undergoing CABG (placebo, n = 861; aprotinin, n = 862) were examined retrospectively. Primary end-points were death, adverse cerebrovascular outcome, myocardial infarction (MI), and pharmacological interventions (inotropic drugs, vasopressors, and antiarrhythmics). RESULTS: Univariate analysis showed that relative to placebo, full-dose aprotinin therapy was associated with significant effects on the incidence of adverse cerebrovascular outcome (odds ratio [OR] 0.42, 95% confidence interval [CI] 0.19–0.93; P = 0.03) and use of inotropic drugs (OR 0.79, 95% CI 0.65–0.97; P = 0.02), vasopressors (OR 0.74, 95% CI 0.61–0.90; P < 0.01), and antiarrhythmics (OR 0.79, 95% CI 0.65–0.96; P = 0.02), but not death (OR = 1.00, 95% CI 0.54–1.85; P = 1.0) or MI (OR 0.92, 95% CI 0.64–1.31; P = 0.6). Multivariate analysis confirmed results of univariate analysis. CONCLUSIONS: This retrospective analysis of data collected from prospective, randomized, placebo-controlled studies in CABG shows that full-dose aprotinin use was associated with a lower risk of adverse cerebrovascular outcomes and a reduced need for use of vasoactive drugs; the risk of death and perioperative MI was not affected by aprotinin therapy.
Preparing nanocomposite fibrous scaffolds of P3HB/nHA for bone tissue engineering

Nanocomposites are recently known to be among the most successful materials in biomedical applications. In this work we sought to fabricate fibrous scaffolds which can mimic the extra cellular matrix of cartilaginous connective tissue not only to a structural extent but with a mechanical and biological analogy. Poly(3-hydroxybutyrate) (P3HB) matrices were reinforced with 5, 10 and 15 %wt hydroxyapatite (HA) nanoparticles and electrospun into nanocomposite fibrous scaffolds. Mechanical properties of each case were compared with that of a P3HB scaffold produced in the same processing condition. Spectroscopic and morphological observations were used for detecting the interaction quality between the constituents. Nanoparticles rested deep within the fibers of 1 µm in diameter. Chemical interactions of hydrogen bonds linked the constituents through the interface. Maximum elastic modulus and mechanical strength was obtained with the presence of 5%wt hydroxyapatite nanoparticles. Above 10%wt, nanoparticles tended to agglomerate and caused the entity to lose its mechanical performance; however, viscoelasticity interfered at this concentration and lead to a delayed failure. In other words, higher elongation at break and a massive work of rupture was observed at 10%wt.
The public perception of protest.

Collective acts of disruption and violence are sometimes viewed as expressions of social protest, and sometimes as crime or rebellion, leading to different community reactions. Five theoretical perspectives can be used to predict when the protest interpretation will be made: (1) events must be credible as protest; (2) an optimal balance is required between appeal and threat; (3) protest interpretation is often an aspect of conciliation to avoid full-scale conflict; (4) protest interpretation can be an invitation to form a coalition; and (5) protest interpretation can be a phase of bargaining by authorities.
Atrial Fibrillation in the Goat Induces Changes in Monophasic Action Potential and mRNA Expression of Ion Channels Involved in Repolarization

MAP Changes and Ion Channel Expression in Goat AF. Introduction: Sustained atrial fibrillation (AF) is characterized by a marked shortening of the atrial effective refractory period (AKRP) and a decrease or reversal of its physiolonic adaptation to heart rate. The aim of the present study was to investigate whether the AF‐induced changes in AKKP in the goat are associated with changes in the atrial monophasic action potential (MAP) and whether an abnormal expression of specific ion channels underlies such changes.
Children with Autism Adapt Normally during a Catching Task Requiring the Cerebellum

The cerebellum, which has been found to be abnormal in histopathological studies of autism, is important for motor adaptation. We studied controls and children with high functioning autism (HFA) performing a catching adaptation test that is known to be impaired following cerebellar damage. Results showed no differences in adaptation rates or after-effects for HFA subjects versus controls. The findings indicate normal motor adaptation in HFA, suggesting normal or compensated cerebellar function for this task.
PLASMID PROFILE ANALYSIS OF SALMONELLAE ISOLATED FROM SOME MEAT PRODUCTS

A total of 300 random samples of luncheon, sausage and frozen minced meat (100 of each) were collected from different supermarkets at Qalyubia governorate. The samples were transferred directly to the laboratory under strict hygienic conditions and bacteriologically examined for detection and plasmid profile analysis of salmonellae. This work determined the plasmid profiles of the salmonella serovars by using ethidium bromid stained 1% agarose gel electrophoresis. In this study, plasmid analysis revealed that the isolated salmonella serotypes carry different numbers of plasmids with variable molecular weights ranged from 1233.18 to 15280.82 base pair (bp). The obtained results revealed that S. typhi, S. typhimurium and S. enteritidis contain a common molecular weight band at 7532.35 bp. and the number of plasmids ranged from 4 to 5 bands. Moreover, S. typhi and S. typhimurium sharing the same band at 1233.18 bp. In the current study, S. enteritidis and S. typhimurium were recognized to have common band at 1631.12 bp. The obtained results revealed that S. typhi, and S. enteritidis have 4 bands but S. typhimurium have 5 bands.
