Can the Psycho-Emotional State be Optimized by Regular Use of Positive Imagery?, Psychological and Electroencephalographic Study of Self-Guided Training

The guided imagery training is considered as an effective method and therefore widely used in modern cognitive psychotherapy, while less is known about the effectiveness of self-guided. The present study investigated the effects of regular use of self-guided positive imagery, applying both subjective (assessment of the psycho-emotional state) and objective (electroencephalographic, EEG) approaches to research. Thirty healthy subjects participated in the cognitive imagery-training program for 12 weeks. The schedule began with group training with an instructor for 2 days, where the participants learned various techniques of positive imagery, after which they continued their individual training at home. Psychological and EEG evaluations were applied at the baseline and at the end of the training period. The impact of training on the psycho-emotional states of the participants was evaluated through: Center for epidemiologic studies- Depression (CES-D) 20 item scale, Satisfaction with life scale (SWLS) and General Self-Efficacy scale (GSE). EEGs (19-channels) were recorded at rest with eyes closed. EEG analysis was performed using Low resolution electromagnetic tomography (LORETA) software that allows the comparison of current source density (CSD) and functional connectivity (lagged phase and coherence) in the default mode network before and after a workout. Initial assessment with CES-D indicated that 22 participants had subthreshold depression. After the training participants had less prominent depressive symptoms (CES-D, p = 0.002), were more satisfied with their lives (SWLS, p = 0.036), and also evaluated themselves as more effective (GSE, p = 0.0002). LORETA source analysis revealed an increase in the CSD in the right mPFC (Brodmann area 10) for beta-2 band after training (p = 0.038). LORETA connectivity analysis demonstrated an increase in lagged coherence between temporal gyruses of both hemispheres in the delta band, as well as between the Posterior cingulate cortex and right BA21 in the theta band after a workout. Since mPFC is involved in emotional regulation, functional changes in this region can be seen in line with the results of psychological tests and their objective validation. A possible activation of GAMK-ergic system is discussed. Self-guided positive imagery (after instructions) can be helpful for emotional selfregulation in healthy subjects and has the potential to be useful in subthreshold depression.
Índice de función sexual en mujeres que ejercen el comercio sexual

PALABRAS CLAVE: Sexualidad, trabajadoras sexual, mujer SUMMARY Background: Sexuality is displayed as a reflection of the level of physical, psychological and social wellbeing. Therefore, negative sexual experiences can affect the entire development as human beings. In Chile, there are no studies that investigate the presence of sexual dysfunctions in the sex worker. Aim: To evaluate the Female Sexual Function Index (FSFI) in women sex workers about their sexual performance with his regular partner and compared with women not sex workers. Methods: Sexually active women over 18 years. We work with purposive intentional non probabilistic sampling. The final number of women studied was 58, of which 23 women were sex workers (study group) and 35 women were not involved in the sex trade (control group). Results: The average age was 33 years for the control group and 35 years in the case of sex workers. 4% of sex workers had university education, 70% were unmarried and used as main contraceptive the IUD. Meanwhile, 34% of the control group had university education, 57% were single and used as primary contraceptive the hormone method. There were no significant differences in overall
Angiotensin‐Like Immunoreactivity in the Brain of the Spontaneously Hypertensive Rat

Evidence for the brain renin-angiotensin system being involved in the hypertension of the spontaneously hypertensive rat (SHR) includes central administration of angiotensin II (All) antagonists and converting enzyme inhibitors that lower blood pressure in SHR. Using the unlabeled antibody enzyme method, we have found a significant difference in the distribution of brain angiotensin in SHR and Wistar-Kyoto controls (WKY). Six rats of each group were perfused with buffered picric acid-paraformaldehyde, and their brains sectioned at 50 and 100 μ. The sections were reacted with a IMOOO dilution of AH antisenim for 36 hours followed by goat antirabbit immunoglobulin G and rabbit peroxidase antiperoxidase. For controls, preabsorption with All, arginine vasopressin or preimmune serum were evaluated. The results showed over twice as many cells and fibers staining for All-like immunoreactivity in SHR. The AH immunoreactive cell bodies were localized, in the order of their relative preponderance, in supraoptic and paraventricular nuclei of the hypothalamus, hippocampus, and cortex. The most prominent demonstration of All-like immunoreactivity was observed in fiber profiles containing densely stained varicosities, which were present in many neuroanatomical subdivisions of the brain and brain stem including anterior and middle hypothalamus, basal ganglia, thalamus, locus coeruleus, nucleus of the solitary tract, limbic structures, and reticular formation. The increased fiber staining in the SHR was particularly evident in the frontal hypothalamic region, medial preoptic, and stria terminalis. We conclude that the results support the hypothesis of brain AH involvement in hypertension. (Hypertension 4:514–523, 1982)
PERCEPÇÃO VISUAL E TATUAL-CINESTÉSICA DE COMPRIMENTO, ÁREA E VOLUME EM OBSERVADORES NORMAIS E CEGOS

Grupos independentes de observadores estimaram visual e tatual-cinestesicamente, atraves do metodo de estimacao de magnitude numerica, comprimentos de linhas, areas irregulares e volumes de cubos. Foram empregados tres grupos experimentais: Visao, Tato Induzido (su­jeitos vendados que julgaram os estimulos atraves do tato-cinestesia) e Tato Natural (cegos congenitos ou adquiridos). Parâmetros da funcao de potencia foram calculados para cada sujeito em cada grupo experimental. Os resultados mostraram que ha uma diferenca significativa entre os jul­gamentos de comprimento, area e volume quando estes sao realizados visualmente. Houve uma diminuicao sistematica dos expoentes em funcao do aumento das dimensoes espaciais (uni, bi e tridimensional) a serem julgadas. Este padrao de resultados sugere que para estimativas visuais parece haver tres canais de transducao sensorial: um para com­primento, outro para area e um outro para volume visual. Para os julga­mentos tatuais-cinestesicos os dados mostraram que nao ha diferencas entre as estimativas de estimulos unidimensionais e bidimensionais, mas ambas sao diferentes das estimativas de estimulos tridimensionais. Este padrao de resultados sugere que para julgamentos tatuais-cinestesicos ha provavelmente dois canais de transducao sensorial: um para estimu­los unidimensionais e bidimensionais, e um outro para estimulos tridimen­sionais.
Bioengineering and Biotechnology Perspective Article Soft Robotics: New Perspectives for Robot Bodyware and Control

The remarkable advances of robotics in the last 50 years, which represent an incredible wealth of knowledge, are based on the fundamental assumption that robots are chains of rigid links. The use of soft materials in robotics, driven not only by new scientific paradigms (biomimetics, morphological computation, and others), but also by many applications (biomedical, service, rescue robots, and many more), is going to overcome these basic assumptions and makes the well-known theories and techniques poorly applicable, opening new perspectives for robot design and control. The current examples of soft robots represent a variety of solutions for actuation and control. Though very first steps, they have the potential for a radical technological change. Soft robotics is not just a new direction of technological development, but a novel approach to robotics, unhinging its fundamentals, with the potential to produce a new generation of robots, in the support of humans in our natural environments. THE SOFT ROBOTICS CHALLENGE Robotics has grown exponentially in the last 50 years and today robotics technologies are very solid and robust, in the accurate, fast, and reliable control of robot motion. Almost all the theories and techniques for robot control, fabrication, and sensing, which represent an incredible wealth of knowledge, are based on a fundamental assumption and conventional definition of robots: a kinematic chain of rigid links. Recent advances in soft and smart materials, compliant mechanisms , and non-linear modeling, on the other hand, have led to a more and more popular use of soft materials in robotics worldwide. This is driven not only by new scientific paradigms (biomimetics, morphological computation, and others) but also by many application requirements (in the fields of biomedical, service, rescue robots, and many more), because of the expected capability of soft robots to interact more easily and effectively with real-world environments (Mazzolai et al., 2012; Pfeifer et al., 2012). In biomimetics, the use of soft materials is suggested by the uncountable examples of animal and vegetal systems. Rigid structures , like skeletons or exoskeletons, are always accompanied by soft tissues. These include mechanisms for varying the material characteristics such as stiffness, elasticity, and surface properties , etc. (Kim et al., 2013) for generating motion through muscles and for facilitating sensing in skins through embedded mechanoreceptors. Compliance, or softness, is also needed for implementing the principles of embodied intelligence, or morphological computation , a modern view of intelligence, attributing a stronger role …
Design of a Mobile Brain Computer Interface-Based Smart Multimedia Controller

Music is a way of expressing our feelings and emotions. Suitable music can positively affect people. However, current multimedia control methods, such as manual selection or automatic random mechanisms, which are now applied broadly in MP3 and CD players, cannot adaptively select suitable music according to the user’s physiological state. In this study, a brain computer interface-based smart multimedia controller was proposed to select music in different situations according to the user’s physiological state. Here, a commercial mobile tablet was used as the multimedia platform, and a wireless multi-channel electroencephalograph (EEG) acquisition module was designed for real-time EEG monitoring. A smart multimedia control program built in the multimedia platform was developed to analyze the user’s EEG feature and select music according his/her state. The relationship between the user’s state and music sorted by listener’s preference was also examined in this study. The experimental results show that real-time music biofeedback according a user’s EEG feature may positively improve the user’s attention state.
Maternal Primary Imprinting Is Established at a Specific Time for Each Gene throughout Oocyte Growth*

Primary imprinting during gametogenesis governs the monoallelic expression/repression of imprinted genes in embryogenesis. Previously, we showed that maternal primary imprinting is disrupted in neonate-derived non-growing oocytes. Here, to investigate precisely when and in what order maternal primary imprinting progresses, we produced parthenogenetic embryos containing one genome from a non-growing or growth-stage oocyte from 1- to 20-day-old mice and one from a fully grown oocyte of adult mice. We used these embryos to analyze the expression of eight imprinted genes:Peg1/Mest, Peg3, Snrpn,Znf127, Ndn, Impact,Igf2r, and p57 KIP2 . The results showed that the imprinting signals for each gene were not all imposed together at a specific time during oocyte growth but rather occurred throughout the period from primary to antral follicle stage oocytes. The developmental ability of the constructed parthenogenetic embryos was gradually reduced as the nuclear donor oocytes grew. These studies provide the first insight into the process of primary imprinting during oocyte growth.
Detecting negation scope is easy, except when it isn’t

Several corpora have been annotated with negation scope—the set of words whose meaning is negated by a cue like the word “not”—leading to the development of classifiers that detect negation scope with high accuracy. We show that for nearly all of these corpora, this high accuracy can be attributed to a single fact: they frequently annotate negation scope as a single span of text delimited by punctuation. For negation scopes not of this form, detection accuracy is low and under-sampling the easy training examples does not substantially improve accuracy. We demonstrate that this is partly an artifact of annotation guidelines, and we argue that future negation scope annotation efforts should focus on these more difficult cases.
Three distinct pneumotypes characterize the microbiome of the lung in BALB/cJ mice

Bacteria can rarely be isolated from normal healthy lungs using conventional culture techniques, supporting the traditional belief that the lungs are sterile. Yet recent studies using next generation sequencing report that bacterial DNA commonly found in the upper respiratory tract (URT) is present at lower levels in the lungs. Interpretation of that finding is complicated by the technical limitations and potential for contamination introduced when dealing with low biomass samples. The current work sought to overcome those limitations to clarify the number, type and source of bacteria present in the lungs of normal mice. Results showed that the oral microbiome is diverse and highly conserved whereas murine lung samples fall into three distinct patterns. 33% of the samples were sterile, as they lacked culturable bacteria and their bacterial DNA content did not differ from background. 9% of samples contained comparatively higher amounts of bacterial DNA whose composition mimicked that detected in the URT. A final group (58%) contained smaller amounts of microbial DNA whose composition was correlating to that of rodent chow and cage bedding, likely acquired by inspiration of food and bedding fragments. By analyzing each sample independently rather than working with group averages, this work eliminated the bias introduced by aspiration-contaminated samples to establish that three distinct microbiome pneumotypes are present in normal murine lungs.
Robust C-RAN Precoder Design for Wireless Fronthaul with Imperfect Channel State Information

Cloud Radio Access Network (C-RAN) architecture with optical fiber fronthaul has been confirmed as a promising solution to achieve high capacity and low latency signal transmission, which has been a key technology and trend of the evolving fifth generation (5G) cellular networks. However, with the fiber fronthaul increasing, the complexity and cost of the CRAN fronthaul networks will grow exponentially. Accordingly, the hybrid fronthaul network of wireless and optical will be the direction of C-RAN architecture design in the future. In this paper, we study the wireless fronthaul C-RAN system in downlink and propose a robust precoder design. The channel state information (CSI) at the baseband unit (BBU) pool and remote radio head (RRH) cluster is assumed to be imperfect, where the additive channel state information error is modeled as Gaussian distributed. Based on this model, we propose a robust C-RAN precoder design that minimizes the total transmit power under a signal-to-interference-plus-noise ratio (SINR) constraint at each user terminal. The original goal is to establish SINR constrained power allocation formulations in the form of convex conic optimization problem. The analysis results reveal that the original problem formulation is non-convex, in general. We develop a novel conservative approximation scheme for handling the non-convex constraint. Furthermore, we solve the optimization problem by transforming it into a semidefinite program with relaxation, which can be efficiently solved. Simulation results show the advantage of using the proposed power-conserving robust precoding algorithm.
Right Sylvian Fissure Subarachnoid Hemorrhage Has Electrocardiographic Consequences

Background and Purpose— Abnormal ECG changes are frequently observed in patients with subarachnoid hemorrhage (SAH). Recently, evidence has been obtained that right insular cortex mediates sympathetic cardiovascular effects. We therefore assessed the laterality and location of SAH dominance in inducing cardiovascular changes as measured by ECG, blood pressure, and heart rate. Methods— After exclusion of 11 SAH patients who died within 1 month after onset, we studied 118 consecutive patients. Data were obtained from records of blood pressure and pulse on admission. Abnormal ECG changes were determined from ECGs on admission and almost 1 month later. From brain CT scans performed immediately after admission, the amount of SAH in each of the 8 cisterns and fissures was measured semiquantitatively. Results— Twenty-six patients had abnormal changes on admission ECG, while 92 patients did not. Systolic blood pressure, diastolic blood pressure, and the amounts of blood in the left ambient cistern, left suprasellar cistern, quadrigeminal cistern, right ambient cistern, right suprasellar cistern, right sylvian fissure, and the set of all cisterns were significantly greater in the group with ECG change than in the group without ECG change. Multivariate logistic regression analysis with stepwise method indicated that systolic blood pressure >160 mm Hg (P =0.0006) and the amounts of SAH in the quadrigeminal cistern (P =0.022) and right sylvian fissure (P =0.0019) were independently associated with abnormal ECG change. Conclusions— Cardiac consequences are possible in patients with massive right sylvian fissure SAH or when systolic blood pressure is >160 mm Hg.
Stereotype Threat and Gender Differences in Performance on a Novel Visuospatial Task

Stereotype threat research has shown that being a member of a negatively stereotyped group may result in impaired performance on tests of skills thought to be relevant to the stereotype. This study investigated whether stereotype threat influences gender differences in performance on a novel test of visuospatial ability. Undergraduates (N = 194) were told that men outperform women on the test (explicit threat), were given no gender-relevant information (implicit threat), or were told that men and women do not differ (nullified stereotype). Although men outperformed women in the explicit and implicit stereotype threat groups, women's performance did not differ significantly from men's when told there is no gender difference. The effect was most pronounced for difficult line judgments. Although stereotypes regarding visuospatial ability may be less culturally salient than those of other cognitive abilities, these findings suggest that they influence performance nonetheless. Implications for optimizing cognitive test performance are discussed.
The Person We Knew: Perceptions of the Identity of Loved Ones With Dementia by Family Caregivers

While several studies have looked at the identity of dementia patients, most focus on the point of the view of the patient. However, caretakers’ and family members’ view of the identity of the dementia patient is unstudied. This study attempts to see how family caregivers’ view of their family member’s dementia manifests in communication about the loved one. This study is a preliminary examination of family caregivers’ constructions of the identity of their loved one, revealing that caretakers have one of three views: the patient without an identity, the patient as a different person, or the patient as “not lost” or gone. Caregivers’ interpretation of the loved one’s identity was seen in how the patient was discussed and treated.
THE EFFECT OF END USER PERCEPTIONS OF INFORMATION TECHNOLOGIES ON THE INFORMATION SHARING

In recent decades, extant studies have focused on dominance of Information Technologies (IT) using different perspectives. While some of these studies utilized domains of IT management, remaining scholarly works dealt with issues of employee perceptions regarding IT usage and how IT usage affects employee outcomes such as job satisfaction. Accordingly, aim of this study is to explore and measure how IT related perceptions of employees determine the use and sharing of information they derive out of using the system effectively. We conceptualized the perceptions in terms of perceived ease of use, perceived usefulness, perceived self-efficacy and perceived information strenght loss. Employee satisfaction will be evaluated as a mediating variable between IT perceptions and information sharing resulting from these employee perceptions. We will test our model using a 114sample unit size of employees from 3 different universities. The obtained data are analyzed through SPSS. Relaibility, normality, factor and regression analysis was conducted in order to test the hypothesis. Whether we could not find any mediation effect of the satisfaction in the model; the results revealed that both the perceived usefulness and ease of use effect knowledge sharing through IT, however satisfaction is only effected by perceived usefulness.
The neuraminidase inhibitor oseltamivir is effective against A/Anhui/1/2013 (H7N9) influenza virus in a mouse model of acute respiratory distress syndrome.

BACKGROUND High mortality and uncertainty about the effectiveness of neuraminidase inhibitors (NAIs) in humans infected with influenza A(H7N9) viruses are public health concerns. METHODS Susceptibility of N9 viruses to NAIs was determined in a fluorescence-based assay. The NAI oseltamivir (5, 20, or 80 mg/kg/day) was administered to BALB/c mice twice daily starting 24, 48, or 72 hours after A/Anhui/1/2013 (H7N9) virus challenge. RESULTS All 12 avian N9 and 3 human H7N9 influenza viruses tested were susceptible to NAIs. Without prior adaptation, A/Anhui/1/2013 (H7N9) caused lethal infection in mice that was restricted to the respiratory tract and resulted in pulmonary edema and acute lung injury with hyaline membrane formation, leading to decreased oxygenation, all characteristics of human acute respiratory distress syndrome. Oseltamivir at 20 and 80 mg/kg protected 80% and 88% of mice when initiated after 24 hours, and the efficacy decreased to 70% and 60%, respectively, when treatment was delayed by 48 hours. Emergence of oseltamivir-resistant variants was not detected. CONCLUSIONS H7N9 viruses are comparable to currently circulating influenza A viruses in susceptibility to NAIs. Based on these animal studies, early treatment is associated with improved outcomes.
