To Tweet, or Not to Tweet: Gender Differences and Potential Positive and Negative Health Outcomes of Adolescents’ Social Internet Use

Adolescents and young adults are avid Internet users. Online social media, such as social networking sites (e.g., Facebook, MySpace), blogs, status updating sites (e.g., Twitter) and chat rooms, have become integral parts of adolescents’ and young adults’ lives. Adolescents are even beginning to enter the world of online dating with several websites dedicated to “teenage online dating. ” This paper reviews recent peer-reviewed literature and national data on 1) adolescents use of online social media, 2) gender differences in online social media and 3) potential positive and negative health outcomes from adolescents’ online social media use. We also examine parental monitoring of adolescents’ online activities. Given that parental supervision is a key protective factor against adolescent risk-taking behavior, it is reasonable to hypothesize that unmonitored Internet use may place adolescents’ at significant risk, such as cyberbullying, unwanted exposure to pornography, and potentially revealing personal information to sexual predators.
Grouping based power control for improving energy efficiency in dense small cell networks

Dense small cell networks (SCNs) has emerged as a cost-effective way of supporting a rapid growth of traffic demand. However, a large number of small cell base stations (SBSs) will consume a lot of energy, which is not conductive to improve the SCNs energy efficiency (EE). In this study, a novel small cell grouping based power control scheme is proposed to save energy as well as to maintain the network throughput for dense SCNs. Specifically, small cells are divided into different groups according to both the load and the inter-cell interference levels between the dense small cells, and accordingly the transmission power of the SBSs is reduced based on the proposed utility function. The existence of the optimal solutions to the problem is discussed, then the differential evolution (DE) is applied to obtain the optimal transmission power. System level simulation results demonstrate that the proposed scheme can significantly improve the SCNs EE without sacrifice of the network throughput.
Continuous Adaptation of the Dialysis Prescription Maintains Adequate Kprt/V in CAPD Patients

Objective To analyze the effect of individual adaptation of the dialysis prescription in continuous ambulatory peritoneal dialysis (CAPD), as compensation for the decline of residual renal function (RRF), on peritoneal (Kpt/V) and total (Kprt/V) urea clearance as well as on peritoneal (Kpcr) and total weekly creatinine clearances (CCr). Design Retrospective analysis of a 2-year period. Patients We analyzed 18 patients [15 male, 3 female; mean age 58.2 (24 – 80) years]. Main Outcome Measures Correlations between increased dialysis prescription and Kpt/V, Kprt/V, and Kpcr. Kprt/V and CCr measurements were based on a 24-hour dialysate and urine collection. Measurements were performed over a time period of 3 to 6 months. Results The results show a linear correlation between Kpt/V and Kpcr and the prescribed volume by kilogram body weight. Kprt/V was increased slightly by increasing the dialysis prescription. Dialysate-to-plasma (D/P) ratios of urea and creatinine remained unchanged. The mean prescribed dialysate volume increased from 7.4 ± 1.1 L to 10.6 ± 2.5 L. Mean Kprt/V could be maintained on a stable level for a 36-month period. Conclusion By adapting the dialysis prescription on an individual basis to the continuous decline of RRF, and taking the patient's body weight into account in the prescription decision, the increases in Kpt/V offset the decline in RRF. We recommend early individualization of prescription for patients on CAPD.
The Model of Masstransfer Intensification in Channels Using Nanowiresets inside and Nanostructures on the Wall

The gas and liquid mass transfer intensification is studied using nanowires placed in the flow as well as nanostractures organized on the channel wall. The results of the study can be applied to a drag reduction of the gas and liquid transport in channels. The model of drag reduction is developed using the set of submicronwires placed into the flow. On the wires surface the gas slippage in Knudsen layer is observed. The slippage results in a mass transfer intensification. The sets of wires placed near the channel axis of symmetry as well as placed close to the channel wall are analyzed for both types of cannel surface that are smooth or have the submicron roughness. The slip boundary condition on the surface of a submicron wire and the subsequent averaging procedure over the set of wires are applied to find the intensity of gas slippage as a function of number density of wires distribution as well as of wires shape. The results of numerical simulation of gas transport under a given pressure drop in channels demonstrate the drag reduction up to 300 percent.
El reconocimiento de los derechos de los pueblos indígenas de El Salvador entre el genocidio continuado y el reencuentro de nuestras raíces

This article reviews the critical path towards the recognition of indigenous peoples in El Salvador from colonial protection laws, through the abolition of such regulations, to the laws of extinction of communal lands during the nineteenth century. Subsequently, the genocide of 1932 and the amnesty granted to the perpetrators as well as the recognition of the rights of indigenous peoples in national and international law in the early years of this century is mentioned. The article concludes by listing the steps to take with indigenous communities to change their reality and to achieve intercultural vision as a country.TEORIA Y PRAXIS Year 14, No.28, January-May 2016, pp. 107-132
EEG Beta Range Dynamics and Emotional Judgments of Face and Voices

The purpose of this study is to clarify multi-modal brain processing related to human emotional judgment. This study aimed to induce a controlled perturbation in the emotional system of the brain by multi-modal stimuli, and to investigate whether such emotional stimuli could induce reproducible and consistent changes in the brain dynamics. As we were especially interested in the temporal dynamics of the brain responses, we studied EEG signals. We exposed twelve subjects to auditory, visual, or combined audio-visual stimuli. Audio stimuli consisted of voice recordings of the Japanese word ‘arigato’ (thank you) pronounced with three different intonations (Angry A, Happy H or Neutral N). Visual stimuli consisted of faces of women expressing the same emotional valences (A, H or N). Audio-visual stimuli were composed using either congruent combinations of faces and voices (e.g. H x H) or non-congruent (e.g. A x H). The data was collected with a 32-channel Biosemi EEG system. We report here significant changes in EEG power and topographies between those conditions. The obtained results demonstrate that EEG could be used as a tool to investigate emotional valence and discriminate various emotions.
Is neurointensive care really optional for comprehensive stroke care?

To the Editor: Expertise matters. The recent recommendations for Comprehensive Stroke Centers (CSC) put forth by the Brain Attack Coalition (BAC) make this argument convincingly using consensus and medical evidence when available.1 This document represents a landmark in advancing the care of stroke patients and will likely have important policy implications for hospitals, administrators, and regulatory agencies in planning for identification, certification, and management of CSCs. Certainly, this has been the case for the certification of Primary Stroke Centers recently implemented by the Joint Commission on Accreditation of Healthcare Organizations. Given the important implications of the CSC recommendations, it is unfortunate that the BAC has actually created recommendations that …
Molecular epidemiological analysis of enterohemorrhagic Escherichia coli infections in Japan.

Infection with enterohemorrhagic Escherichia coli (EHEC) serogroup O157 is one of the significant emerging diseases globally, which causes a variety of symptoms such as abdominal cramps, diarrhea and hemorrhagic colitis. As a serious complication, the haemolytic uremic syndrome (HUS) sometimes occurrs, which can lead to the death of the patient (1). Since the bacteria were first found in the North America in 1982, they have been isolated in many places around the world, especially in developed countries (2). Although our knowledge of the virulence mechanisms of this pathogen is still limited, the pathogenic factors of EHEC seem to consist of at least three independent elements: Shiga toxin (Stx) (3), which is cytotoxic for Vero cells and presently classified in two broad types, Stx1 and Stx2, is encoded by a temperent phage and associated with hemolytic uremic syndrome (1); the chromosomal LEE locus (4), which is a 35kb element also present in enteropathogenic E. coli and encodes genetic factors involved in the attaching and effacing process; a large plasmid carrying the hemolysin genes, of which role during infection is still unknow, but a correlation between the occurrence of the HUS and the presence of the hemolysin genes has been observed (5). In Japan, since an EHEC O157:H7 outbreak in which two out of 268 patients died of HUS occurred in a kindergarten at Urawa City of Saitama Prefecture in 1990, which cause was attributed to well water contaminated by the pathogen, a great attention has been drawn to this disease. We then established reporting system of EHEC isolates by the cooperation with prefectural and manucipal public health institutes (PHIs) and every report of EHEC isolation has been collected to IASR (Infectious Agents Surveillance Report) in NIID (National Institute of Infectious Diseases) since 1991. Until 1995, such reports of isolation
A Sieving ANN for Emotion-Based Movie Clip Classification

Effective classification and analysis of semantic contents are very important for the content-based indexing and retrieval of video database. Our research attempts to classify movie clips into three groups of commonly elicited emotions, namely excitement, joy and sadness, based on a set of abstract-level semantic features extracted from the film sequence. In particular, these features consist of six visual and audio measures grounded on the artistic film theories. A unique sieving-structured neural network is proposed to be the classifying model due to its robustness. The performance of the proposed model is tested with 101 movie clips excerpted from 24 award-winning and well-known Hollywood feature films. The experimental result of 97.8% correct classification rate, measured against the collected human-judges, indicates the great potential of using abstract-level semantic features as an engineered tool for the application of video-content retrieval/indexing.
Smooth Muscle Cell Outgrowth from Coronary Atherectomy Specimens in vitro Is Associated with Less Time to Restenosis and Expression of a Key Transcription Factor KLF5/BTEB2

Atherectomy specimens offer an opportunity to study the biology of coronary artery lesions. We cultured smooth muscle cells (SMCs) from specimens obtained from 24 patients with coronary restenosis after angioplasty to study the relationship between activity of SMCs (in vitro outgrowth) and the time course of restenosis. We also examined expression of a Kruppel-like zinc-finger transcription factor 5 (KLF; also known as BTEB2 and IKLF), which is markedly induced in activated SMCs, in the same specimens. SMC outgrowth was observed in 9 of 24 specimens (37.5%). Restenosis occurred sooner (p < 0.01) in patients whose specimens showed outgrowth compared to those whose specimens showed no outgrowth. Immunostaining for KLF5 was more common in specimens with outgrowth (89 vs. 20%, p < 0.01). These data suggest that the number of activated SMCs in lesions may determine in vitro outgrowth and also affect the time to restenosis.
“Too Many betas do not Spoil the Broth”: The Role of Beta Brain Oscillations in Language Processing

Over the past 20 years, brain oscillations have proven to be a gateway to the understanding of cognitive processes. It has been shown that different neurocognitive aspects of language processing are associated with brain oscillations at various frequencies. Frequencies in the beta range (13–30 Hz) turned out to be particularly important with respect to cognitive and linguistic manipulations during language processing. Beta activity has been involved in higher-order linguistic functions such as the discrimination of word categories and the retrieval of action semantics as well as semantic memory, and syntactic binding processes, which support meaning construction during sentence processing. From a neurophysiological point of view, the important role of the beta frequencies for such a complex cognitive task as language processing seems reasonable. Experimental evidence suggests that frequencies in the beta range are ideal for maintaining and preserving the activity of neuronal assemblies over time. In particular, recent computational and experimental evidence suggest that beta frequencies are important for linking past and present input and the detection of novelty of stimuli, which are essential processes for language perception as well as production. In addition, the beta frequency’s role in the formation of cell assemblies underlying short-term memory seems indispensable for language analysis. Probably the most important point is the well-known relation of beta oscillations with motor processes. It can be speculated that beta activities reflect the close relationship between language comprehension and motor functions, which is one of the core claims of current theories on embodied cognition. In this article, the importance of beta oscillations for language processing is reviewed based both on findings in psychophysiological and neurophysiological literature.
Accesibilidad del Financiamiento Agropecuario en Ameca, Jalisco, México

La agricultura en Mexico se ha polarizado en campesina y empresarial, esta ultima se distingue por ser mas tecnificada. Un factor importante para pasar de la agricultura campesina a una empresarial es el credito refaccionario, sin embargo, el sector agropecuario ha sufrido escasez en financiamiento debido a los riesgos que presenta el mismo; estos hacen que los intermediarios financieros tengan incertidumbre sobre el cumplimiento de pago del productor agropecuario y, por ende, la mayor parte de sus recursos se dirigen a otros sectores. Por otro lado, tambien los productores agropecuarios tienen incertidumbre, ya que hacer una inversion en un ambito riesgoso como la agricultura tiende a que los productores sean adversos al riesgo por lo que no gestionan credito. No obstante, hay productores que acceden al credito, los cuales se caracterizan por diferentes factores, mismos que hacen que la incertidumbre del intermediario disminuya y asi se otorgue el credito. En este estudio se indaga a traves de un proceso estadistico lineal en los factores del productor que reducen la incertidumbre y provocan un mayor acceso al credito, el cual demuestra que el tamano de la unidad productiva, ingreso, seguranza, entre otros, impacta positivamente en el acceso al credito en una institucion formal.
Nutritional evaluation of poultry by-product meal as a protein source for ruminants: effects on performance and nutrient flow and disappearance in steers.

We conducted three studies with steers to evaluate poultry by-product meal (PBM) as a supplemental N source for ruminants. An in situ study compared the solubility, degradation rate, and ruminal escape of PBM N with blood meal (BM), corn gluten meal (CGM), and soybean meal (SBM) N. Additionally, an 84-d growth study (n = 95, 228+/-5 kg BW) and a digestion trial (6 x 6 Latin square) were conducted. The basal diet for the growth and digestion studies consisted of 49% corn silage, 36% cottonseed hulls, and 15% supplement (DM basis). Sources of supplemental N (% of total supplemental N) were 100% SBM and 0, 25, 50, 75, and 100% PBM, with urea used to balance for N. In situ ruminal escape N (25.2, 55.3, 86.7, and 98.9% for SBM, PBM, CGM, and BM, respectively) was greater (P < .05) for PBM than for SBM; however, a greater (P < .05) proportion of BM and CGM N escaped ruminal degradation compared with PBM. Dry matter intake, ADG and gain/ feed increased linearly (P < .003) as PBM increased; however, no differences (P > .48) were observed in these variables for 100% PBM compared with 100% SBM. Duodenal N flow and small intestinal N disappearance increased linearly (P < .05) as PBM increased in the diet. Bacterial N flow to the small intestine was not affected (P > .19) by treatment; however, 100% SBM decreased (P < .04) bacterial CP synthesis (g bacterial N/kg OM disappearance from the stomach) compared with 0 and 100% PBM. In vivo ruminal escape N of PBM and SBM was 40.6 and 13.7%, respectively. Ruminal NH3 N decreased linearly (P < .001) as PBM increased. These data suggest that PBM can replace SBM as a source of supplemental N for steer calves that consume a diet based on corn silage and cottonseed hulls.
Developing Entrepreneurial Education at the University Focused on Start-ups

Research have shown that majority of start-ups fail. The reasons can be expressed as follows: premature scaling, poor product, ignoring customer needs, etc. This failure is caused by the lack of entrepreneurial skills of founders and their co-workers. Creating favorable start-up ecosystem requires cooperation of many stakeholders such as companies, public institutions (universities, self-governing regions, etc.) as well as enthusiastic individuals. Universities play crucial role in the ecosystem creation. They are actively trying to prepare students for their entrepreneurial career. They are organizing events as well as offering courses, which should help students to succeed with their start-ups. This paper describes the development of an entrepreneurial course at the University of Žilina. There was used case study method for describing several years of experiences with creation of such a course. Authors have tested various approaches in order to develop complex system of startup education which consists of university course, related thematic events and practical experience for students aiming to establish their own business. The system consists of using simple visual tools and related practical activities which will further improve their entrepreneurial knowledge. This proposed system serves as a basis for future research.
Cardiomyopathy Induced by Anthracycline‐Derivates

ABSTRACT. Two cases of anthracycline‐induced congestive heart failure are described. Serial assessment of cardiac function during treatment showed early deterioration of the systolic time intervals of the left ventricle (LSTI) before congestive cardiomyopathy could be demonstrated by echocardiography. We recommend that the cardiac function should be assessed regularly during anthracycline therapy by systolic time intervals and echocardiography to reveal early signs of cardiotoxic effect and that anthracycline therapy should be stopped when LSTI is 0.45 or when it has increased more than 50 % compared to pretreatment values
The assessment and evaluation of daily physical activity in children. A review

ABSTRACT. Related to the prevention of coronary heart disease (CHD) daily physical activity in children has become a field of interest. Epidemiological studies have shown that physical activity appears to offer some degree of protection against CHD. Hence a fundamental approach for prevention should begin at childhood. This review covers the state of the art within selected areas of the measurement of physical activity and their relationship to risk indicators of CHD. The areas addressed include the following: the use of different field methods to measure daily physical activity, methodological constraints in children and finally the role of physical activity, physical fitness and training in relation to the risk indicators of CHD in children.
Arabidopsis BRS1 Is a Secreted and Active Serine Carboxypeptidase*

The Arabidopsis BRS1 gene encodes a serine carboxypeptidase II-like protein. Its biological role in the brassinosteroid signaling pathway was first established by its capability to specifically suppress a weak brassinosteroid insensitive 1 (bri1) allele, bri1-5, when overexpressed. To gain additional insights into the molecular mechanisms of BRS1 function, the subcellular localization and the biochemical characteristics of BRS1 were determined by using transgenic plants harboring a 35S-BRS1-GFP construct and fusion proteins purified from 35S-BRS1-FLAG transgenic plants. The BRS1-GFP protein was mainly secreted and accumulated in the extracellular space. Immunological data suggest that BRS1 is proteolytically processed by an unknown endoproteinase in planta. Affinity-purified BRS1-FLAG from transgenic plants show strong hydrolytic activity with a broad P1 substrate preference including basic and hydrophobic groups on either side of the scissile bond. The hydrolytic activity of BRS1 can be strongly inhibited by a serine protease inhibitor, phenylmethylsulfonyl fluoride. The pH and temperature optima for the hydrolytic activity of BRS1 are pH 5.5 and 50 °C, respectively. These data demonstrate that BRS1 is a secreted and active serine carboxypeptidase, consistent with the hypothesis suggested by our previous genetic evidence that BRS1 may process a protein involved in an early event in the BRI1 signaling pathway.
ABC of the upper gastrointestinal tract: Anorexia, nausea, vomiting, and pain.

With the steady decline in diseases associated with Helicobacter pylori infection, the commonest diagnosis, both in general practice and hospital outpatients, is increasingly likely to be functional dyspepsia, a condition that is ill understood and for which management is poorly defined. [][1] Taking an emetic by Isaac Cruickshank (1757–1810) Although upper abdominal and epigastric pain is extremely common and hence a poor discriminator of disease, only 2-8% of the general population experience anorexia, nausea, and vomiting, and so these are much more likely to indicate disease. Thankfully, many of these events turn out to be short lived, and only about 25% of those affected consult their general practitioner, but this still accounts for 1-2% of all consultations in general practice. Two thirds of patients give the severity of their symptoms as a reason for consulting, but a similar proportion consult because of fear of serious disease, a factor that must be considered when planning management. The challenge is to reliably sift out and satisfactorily reassure the 40% with functional disease without missing those with more serious pathology. Anorexia, nausea, and vomiting with pain can all be regarded teleologically as protective reflexes whereby the body prevents the entry of toxins into the body. They also reduce the passage of chyme through diseased parts of the upper gut, thereby minimising further pain. View this table: Prevalence of symptoms in general population There are many possible organic causes, but, because there is an important central component, these behaviour patterns can be learnt and may be anticipatory. Thus, patients about to receive chemotherapy may vomit at the sight of the drugs, which they have previously associated with vomiting. Anxiety and depression can also be associated with alterations in taste—with associated anorexia, nausea, and weight loss—through neural pathways as yet poorly defined. Toxins and hypertonic saline induce vomiting by … [1]: /embed/graphic-1.gif
