Multinodular and Vacuolating Neuronal Tumor of the Cerebrum: A New “Leave Me Alone” Lesion with a Characteristic Imaging Pattern

The most recent 2016 WHO classification includes MVNT as a unique cytoarchitectural pattern of gangliocytoma, though it remains unclear whether MVNT is a true neoplastic process or a dysplastic hamartomatous/malformative lesion. The authors report 33 cases of presumed multinodular and vacuolating neuronal tumor of the cerebrum that exhibit a remarkably similar pattern of imaging findings consisting of a subcortical cluster of nodular lesions. They conclude that these are benign, nonaggressive lesions that do not require biopsy in asymptomatic patients and behave more like a malformative process than a true neoplasm. SUMMARY: Multinodular and vacuolating neuronal tumor of the cerebrum is a recently reported benign, mixed glial neuronal lesion that is included in the 2016 updated World Health Organization classification of brain neoplasms as a unique cytoarchitectural pattern of gangliocytoma. We report 33 cases of presumed multinodular and vacuolating neuronal tumor of the cerebrum that exhibit a remarkably similar pattern of imaging findings consisting of a subcortical cluster of nodular lesions located on the inner surface of an otherwise normal-appearing cortex, principally within the deep cortical ribbon and superficial subcortical white matter, which is hyperintense on FLAIR. Only 4 of our cases are biopsy-proven because most were asymptomatic and incidentally discovered. The remaining were followed for a minimum of 24 months (mean, 3 years) without interval change. We demonstrate that these are benign, nonaggressive lesions that do not require biopsy in asymptomatic patients and behave more like a malformative process than a true neoplasm.
Emotional intelligence and conflict resolution strategies in romantic heterosexual couples

This study investigated the relationships between emotional intelligence (EI) and confl ict resolution strategies in romantic heterosexual couples. 164 couples solved the Test of Emotional Intelligence (TIE), a Polish measure based on the ability model of EI, and the Problem-Solving Strategies Inventory (PSSI) in two versions: self-report and a report of partner’s behavior. We assumed that individuals high in EI should have superior confl ict resolution skills and engage in active and constructive strategies, avoiding those characterized as passive and destructive. These hypotheses were supported for women, but not for men. Females’ EI was consistently positively related to self-report measures of Voice, and negatively related to self-reports of Neglect. Emotionally intelligent men did not declare use of more constructive or positive confl ict resolution styles; however, their female partners judged them as more prone to use of those strategies. The results also revealed a positive assortative mating effect with regard to EI. Additionally, the study demonstrated an interesting disparity between male and female’s reports on relationship behaviors.
Attentional Focusing Strategies Influence Muscle Activity During Isokinetic Biceps Curls

The present study assessed the influence of different attentional focusing instructions upon muscular activity during biceps curl movements. Twenty-nine participants carried out 10 biceps curl repetitions on an isokinetic dynamometer at 60oas-1 using control, internal (focusing upon arm movements) and external (focusing upon movement of the bar) attentional focusing strategies whilst Electromyography (EMG) activity of the biceps brachii was recorded. Significantly higher levels of EMG activity were observed in the internal and control conditions when compared to when an external strategy was used. When data was normalised against the control condition, the internal strategy resulted in significantly higher levels of EMG activity when compared to the external strategy. Attentional focusing strategies and instructions influence the observed muscular activity, which has direct implications for both skill execution and physical training settings. Coaches, trainers, and physiotherapists should be aware of the effects that different instructional emphases can have at a muscular level.
Dependable wireless mesh networks: An integrated approach

Wireless Mesh Networks (WMNs) are replacing wireless Infrastructure networks in many areas because of their lower cost and higher flexibility. However, applications in the Process Industry and Telerobotics field require not only flexible but also dependable service, which is not provided by existing solutions. To make a WMN dependable, many problems have to be solved on different layers. With this paper, we describe our ongoing work to provide an integrated solution to increase the dependability of WMNs. Our approach combines network coverage planning on the physical layer, bandwidth management on the link layer and live network monitoring to improve the reliability, availability and maintainability of a WMN. We provide fine-grained means to improve the predictability of the network components, thus making the WMN more dependable. In this paper, we present first results of our ongoing work, and describe how they are interleaved.
A Passive Mixer for a Wideband TV Tuner

This brief presents the design of a direct conversion mixer for a wideband television tuner operating at 48-860 MHz. The mixer consists of a transconductance stage, a passive current switching stage, and a transimpedance amplifier stage. In the switching stage, by adopting an opposite phase auxiliary switching quad configured in parallel with the main switching quad, the unwanted harmonics at the output of the switching stage are suppressed, thereby preventing mixer linearity degradation at low input frequencies. The proposed mixer is implemented in a 0.13-μm CMOS technology, and measurements show more than a 19.5-dB voltage gain, 12-dB noise figure, and 8-dBm IIP3 over the entire operating band of 48-860 MHz while dissipating 4.5 mA from a 1.2-V supply.
Analysis of the Soft Tissue Facial Profile of Croatians Using of Linear Measurements

One hundred and ten subjects (52 males and 58 females) between 23-28 years of age with dental Class I occlusal relationship, good soft tissue profile, and Caucasian ethnicity were selected from the population of dental students at the University of Zagreb, Croatia. The soft tissue facial profiles were digitally analyzed using linear (11 vertical and 14 horizontal) measurements made with standardized photographic records, taken in natural head position, to determine average soft tissue facial profile for males and females. The application of Student t-test showed gender dimorphism in most parameters of the labial, nasal. and chin areas. Almost all vertical variables were larger in the males, except the length of the nasal tip, which was larger in females. In the height of the vermilion, no gender dimorphism was observed. The females exhibited shallower labial sulci than the males and their chins were at least as prominent as those of the males. This study showed that male chins are not absolutely more prominent than female chins, but only appear to be such because their labial sulci are deeper.
The impact of social networking technology on students

Social networking includes social networking sites (SNSs) as well as apps. The purpose of this thesis was to investigate the impact of social networking tech-nology on students. The research questions focused how university students experience their interaction with social networking regarding advantages and disadvantages, and for what purposes they are using it personal, professional or study). A quantitative surveys study was used and data was collected through online questionnaires delivered via SNSs, e-mails and through delivery and col-lection method. 122 valid responses were collected and 17 invalid responses were discarded. The questionnaire framework was built by means of the con-cept of ease of use from Technology Acceptance Model (TAM) and the five values of Uses and Gratification Theory; “purposive value”, “self-discovery”, “maintaining interpersonal interconnectivity”, “social enhancement value” and “entertainment value”. The findings showed that 64% considered themselves to be positively influenced by SNSs and 27% to be neither positively or nega-tively influenced. Only 11 % considered that SNSs influenced them negatively. According to our findings, some of the most frequent advantages are keeping in touch with family and friends, cost and time efficient, easy to use and entertaining. And for the disadvantages, the responses were mostly time consuming, health issues, privacy issues, addiction to technology and cyber bulling. The majority of respondents reported using SNS firstly for personal use, secondly for study use and the professional use was the least selected. 88% of the respondents thought that it is easy to use SNSs. The purposive value of SNS use was to get information, the self-discovery value to learning about oneself and others, for the maintaining interpersonal connectivity, to stay in touch, and for the entertainment value, it was to pass time away when bored. The results indicated that the social enhancement value was not very important for the respondents.
Current Directions in Psychological

Successful negotiation of everyday life would seem to require people to possess insight about deficiencies in their intellectual and social skills. However, people tend to be blissfully unaware of their incompetence. This lack of awareness arises because poor performers are doubly cursed: Their lack of skill deprives them not only of the ability to produce correct responses, but also of the expertise necessary to surmise that they are not producing them. People base their perceptions of performance, in part, on their preconceived notions about their skills. Because these notions often do not correlate with objective performance, they can lead people to make judgments about their performance that have little to do with actual accomplishment.

Outflow : Visualizing Patient Flow by Symptoms and Outcome

Electronic Medical Record (EMR) databases contain a large amount of temporal events such as diagnosis dates for various symptoms. Analyzing disease progression pathways in terms of these observed events can provide important insights into how diseases evolve over time. Moreover, connecting these pathways to the eventual outcomes of the corresponding patients can help clinicians understand how certain progression paths may lead to better or worse outcomes. In this paper, we describe the Outflow visualization technique, designed to summarize temporal event data that has been extracted from the EMRs of a cohort of patients. We include sample analyses to show examples of the insights that can be learned from this visualization.
Optimum spreading bandwidth for selective RAKE reception over Rayleigh fading channels

Building on the developments in the performance analysis of generalized selection combining (GSC), this paper examines the optimum spreading bandwidth for a fixed-complexity GSC diversity receiver operating over independent identically distributed Rayleigh paths. For this purpose, the study considers three performance criteria: (1) average combined signal-to-noise ratio (SNR) at the GSC output; (2) average bit error probability (BEP); and (3) outage probability of the instantaneous combined SNR at the GSC output. For the average BEP criterion, results are presented for both coherent and noncoherent combining. For the average combined SNR and some instances of the average BEP optimization problem, an accurate approximate estimate of this optimum bandwidth in the form of a solution of a transcendental equation is provided. In other cases, where the optimization is not easily tractable in an analytic fashion, a numeric-search procedure is used to find this optimum bandwidth for different performance criteria and system parameters of interest. Finally, simplified rule-of-thumb-type formulas are also presented as a good reference for picking the optimum spreading bandwidth given a set of system parameters and a particular performance criterion of interest.
Photic Driving in Migraine

In this issue of Cepkalalgia, the study by Puca et al. on steady state visual evoked potentials provides additional data confirming that hyperexcitability to light is a hallmark of the cerebral cortex in migraineurs between attacks. Since the seminal observation by Golla & Winter (1) of an increased photic drive of the EEG in migraineurs, cortical hyperreactivity to visual stimuli has been demonstrated with various methods, e.g. epidemiological surveys (2) functional tests (3, 4), steady state (5) , flash (6) or pattern reversal (7, 8) evoked potentials. It is not clear whether the cortical hyperexcitability is due to lack of inhibition by intrinsic GABAergic neurons (4) or to an abnormal modulation of the cortex by subcortical (monoaminergic) pathways (9). It was hypothesized that the former, which postulates a loss of cortical interneurons, might be an acquired consequence of repeated insults (hypoxia/spreading depression) to the visual cortex, while the latter could be a genetic abnormality. One major interest of Puca et al.’s study is that they find a positive correlation between visual reactivity and family history of migraine or autonomic symptoms during the attack, which favors the hypothesis of an inherited, subcortical dysfunction. Unfortunately, the reliability of information concerning severity of attack-associated symptoms and affected family members can be questioned in the absence of diary card data and of family interviews. Because of their importance for migraine pathogenesis, the correlations found here need to be confirmed using these more stringent methods.
Overview of results obtained at the Globus-M spherical tokamak

Experiments and simulations to achieve high values of plasma parameters at the Globus-M spherical tokamak (ST) at moderate absolute auxiliary heating power (up to 0.8 MW) and high specific heating power (up to 2–3 MW m−3) are described. Important distinguishing features are the low edge safety factor range, which is unusual for STs, 2.7 < q < 5 and small plasma–outer wall space (3–5 cm). High ion heating efficiency with neutral beam injection (NBI) was demonstrated. Results of numerical simulation of fast ion trajectories are described and fast ion generation during the NBI and ion cyclotron resonance heating is discussed. Investigations on their confinement and slowing down are also presented. Reasons for achievement of high IC heating efficiency are outlined. Reliable H-mode regime achievement is described. Transport ASTRA modelling demonstrated that during NB heated H-mode ion heat diffusivity remains neoclassical and the particle diffusion coefficient inside transport barrier decreases significantly. Analysis was performed of divertor tile and special probe surfaces after irradiation by plasma during a large number of shots (3000–10 000 shots). Mixed layer composition is measured and deuterium retention in different tokamak first wall areas is estimated. Plasma jet injection experiments with upgraded plasma jet are described. Jet penetration to the plasma centre with immediate increase of density and temperature drop is proved and analogy with pellet injection is outlined.
Directional Gene Movement from Human-Pathogenic to Commensal-Like Streptococci

Group A streptococci (GAS) are highly pathogenic for humans, and their closest genetic relatives, group C and G streptococci (GCS and GGS, respectively), are generally regarded as commensals, although they can be found in association with human disease. As part of an effort to better understand the evolution of virulence, the phylogenetic relationships between GAS, GCS, and GGS were examined. The nucleotide sequence was determined for an internal portion of seven housekeeping (neutral) loci among >200 isolates of GAS and 34 isolates of GCS or GGS obtained from human subjects. Genotypic analysis failed to show support for the separation of GCS and GGS into two distinct populations. Unlike GAS, there was poor concordance between emm type and genetic relatedness among GCS and GGS. All housekeeping genes within GAS displayed relatively low levels of sequence diversity. In contrast, individual GCS and GGS strains had mosaic genomes, containing alleles at some loci that were similar or identical to GAS alleles, whereas the alleles at other loci were about 10 to 30% diverged. The data provide evidence for a history of recent interspecies transfer of neutral genes that exhibits a strong net directionality from GAS donors to GCS and GGS recipients. A model for the evolution of GAS and of GCS and GGS is described. We have uncertainties as to the overall strength of the main conclusion on interspecies gene transfer of highly divergent housekeeping gene alleles from group A streptococci (GAS) to group C and G streptococci (GCS/GGS), due to an inability to replicate some of the original GCS/GGS-derived sequence data. The reasons may be that (i) the GCS/GGS DNA template used for PCR ampliﬁcation was contaminated with trace amounts of GAS DNA and/or (ii) there are subtleties with the PCR ampliﬁcation conditions that could not be replicated due to changes in commercial reagents, thermal cyclers, etc. A clear-cut resolution of this matter may require whole-genome sequencing and assembly for at least a few GCS/GGS strains.
The conjunctiva in corneal epithelial wound healing

BACKGROUND/AIMS During the healing of corneal epithelial wounds with limbal involvement, conjunctival epithelium often migrates across the denuded limbus to cover the corneal surface. It is believed that, over a period of time, conjunctival epithelium covering the cornea assumes characteristics of corneal epithelium by a process referred to as conjunctival transdifferentiation. The purpose of this study was to examine, clinically, the fate of conjunctival epithelial cells covering the cornea and to assess the healing of corneal epithelial wounds when the conjunctival epithelium was removed or actively prevented from crossing the limbus and extending onto the cornea. METHODS 10 patients with conjunctivalisation of the cornea were followed for an average of 7.5 months. Five patients in this group had their conjunctival epithelium removed from the corneal surface and allowed to heal from the remaining intact corneal epithelium. In another four patients with corneal epithelial defects, the conjunctival epithelium was actively prevented from crossing the limbus by mechanically scraping it off. RESULTS The area of cornea covered by conjunctival epithelium appeared thin, irregular, attracted new vessels and was prone to recurrent erosions. Conjunctivalisation of the visual axis affected vision. Removal of conjunctival epithelium from the cornea allowed cells of corneal epithelial phenotype to cover the denuded area with alleviation of symptoms and improvement of vision. It was also established that migration of conjunctival epithelium onto corneal surface could be anticipated by close monitoring of the healing of corneal epithelial wounds, and prevented by scraping off conjunctival epithelium before it reached the limbus. CONCLUSION This study shows that there is little clinical evidence to support the concept that conjunctival transdifferentiation per se, occurs in humans. “Replacement” of conjunctival epithelium by corneal epithelial cells may be an important mechanism by which conjunctival “transdifferentiation” may occur. In patients with partial stem cell deficiency this approach can be a useful and effective alternative to partial limbal transplantation, as is currently practised.
Video behaviour profiling and abnormality detection without manual labelling

A novel framework is developed for automatic behaviour profiling and abnormality sampling/detection without any manual labelling of the training dataset. Natural grouping of behaviour patterns is discovered through unsupervised model selection and feature selection on the eigenvectors of a normalised affinity matrix. Our experiments demonstrate that a behaviour model trained using an unlabelled dataset is superior to those trained using the same but labelled dataset in detecting abnormality from an unseen video
[Nursing beliefs and actions in exercising patient advocacy in a hospital context].

OBJECTIVE Analyzing beliefs and actions of nurses in exercising patient advocacy in a hospital context. METHOD A quantitative cross-sectional exploratory and descriptive study, conducted with 153 nurses from two hospitals in southern Brazil, one public and one philanthropic, by applying Protective Nursing Advocacy Scale - Brazilian version. Data were analyzed using descriptive statistics and analysis of variance. RESULTS Nurses believe they are advocating for patients in their workplaces, and agree that they should advocate, especially when vulnerable patients need their protection. Personal values and professional skills have been identified as major sources of support for the practice of advocacy. CONCLUSION Nurses do not disagree nor agree that advocating for patients in their working environments can bring them negative consequences. It is necessary to recognize how the characteristics of public and private institutions have helped or not helped in exercising patient advocacy by nurses.
Influence of Fuel Moisture Content and Reactor Temperature on the Calorific Value of Syngas Resulted from Gasification of Oil Palm Fronds

Biomass wastes produced from oil palm mills and plantations include empty fruit bunches (EFBs), shells, fibers, trunks, and oil palm fronds (OPF). EFBs and shells are partially utilized as boiler fuel while the rest of the biomass materials like OPF have not been utilized for energy generation. No previous study has been reported on gasification of oil palm fronds (OPF) biomass for the production of fuel gas. In this paper, the effect of moisture content of fuel and reactor temperature on downdraft gasification of OPF was experimentally investigated using a lab scale gasifier of capacity 50 kW. In addition, results obtained from equilibrium model of gasification that was developed for facilitating the prediction of syngas composition are compared with experimental data. Comparison of simulation results for predicting calorific value of syngas with the experimental results showed a satisfactory agreement with a mean error of 0.1 MJ/Nm3. For a biomass moisture content of 29%, the resulting calorific value for the syngas was found to be only 2.63 MJ/Nm3, as compared to nearly double (4.95 MJ/Nm3) for biomass moisture content of 22%. A calorific value as high as 5.57 MJ/Nm3 was recorded for higher oxidation zone temperature values.
