Low rate of oropharyngeal human papillomavirus infection of women with cervical lesions and their partners: new data from Brazilian population.

BACKGROUND Although the natural history of cervical and oral infection by human papillomavirus (HPV) has been intensely investigated, the ability of this virus to infect oral and genital mucosae in the same individual and its potential of communicability are still unclear. OBJECTIVES This study aimed at assessing the presence of oropharyngeal HPV infection in women with cervical lesions and in their current sexual partners in a Brazilian population. METHODS It included a total of 65 patients, 43 women and 22 male partners. Medical history and the sociobehavioral profile were assessed through interviews that included the association of oropharyngeal HPV and the sexual behavior of patients, and also extra and intra-oral examinations were performed. Brushing was used to collect cells from the oropharyngeal mucosa. HPV DNA was checked through nested PCR with primers PGMY09/11 and GP5+/6+, and Pappilocheck to genotyping. RESULTS Oropharyngeal HPV infection was detected in four of 65 (6.15%) cases, with one of 43 (2.3%) women, and three of 22 (13.6%) male partners. Clinically no patient showed HPV-related oral lesions. Pappilocheck assay showed the absence of HPV genotype commonly found in cervical mucosa. Moreover, there was no correlation between the presence of oropharyngeal HPV and sexual behavior risk factors. CONCLUSIONS The results suggest that the presence of cervical lesions does not lead to HPV oropharyngeal infection. It also highlights the low rate of HPV infection in the oropharyngeal mucosa of women with cervical lesions and their partners in a researched sample.
Vision Rehabilitation of Persons with Age Related Macular Degeneration

As the population of the United States ages, there is an increase in the number of persons with age related macular degeneration (ARMD). Even as new prevention and treatment techniques are developed, the vision loss associated with ARMD may lead to loss of independence and quality of life. Low vision is a rehabilitative process designed to improve visual function and restore independence. This paper is a review of the current research related to low vision in the areas of magnification, contrast and illumination, reading, training, driving and outcomes assessment.
Sinusoidal Signal Analysis of Electroporation in Biological Cells

Conductivity measurements in suspensions of biological cells have been used since many years for electroporation effectiveness evaluation. However, conductivity modeling by means of instantaneous values of current and voltage during pulse application does not take into account the effects of the sample reactance and the dielectric dispersion of the medium. This can lead to misinterpretation in the electroporation analysis. The electrical modeling and characterization of electroporation using sinusoidal signal analysis at 10 kHz proposed in this paper allows us to avoid distortions due to reactive effects of the sample. A simple equation establishes the relation between suspension conductivity and membrane conductance. This model was used in experiments with suspensions of yeast cells and applied electric fields of up to 450 kV/m for 1 ms. The analysis using the proposed model resulted in membrane conductance values of up to 8000 S/m2 and allowed estimating the distribution profile of conductance on the cell membrane.
Overview of international teledermatology

Teledermatology is essentially “dermatology at a distance”, using one of many communication technologies to expand the reach of a dermatologist to those in need of their specialized knowledge. Most international teledermatology is store-and-forward in nature, a method in which images are stored on a computer and then transmitted electronically to a consulting dermatologist. This system is more convenient and less costly than real-time teledermatology. This review will focus on several of the store-and-forward teledermatology systems being developed and utilized successfully internationally. This discussion of “who” is practicing teledermatology is not comprehensive, but attempts to show some of the breadth of teledermatology practice around the world, including government national health plans, commercial endeavors, and charitable work by individuals and institutions. The goal in many instances is to provide better health outcomes through increased access, efficiency, and/or cost-effectiveness. More studies ultimately need to be conducted to develop a more comprehensive and sustainable model for teledermatology.
Collapsing flow topology using area metrics

Visualization of topological information of a vector field can provide useful information on the structure of the field. However, in turbulent flows standard critical point visualization will result in a cluttered image which is difficult to interpret. This paper presents a technique for collapsing topologies. The governing idea is to classify the importance of the critical points in the topology. By only displaying the more important critical points, a simplified depiction of the topology can be provided. Flow consistency is maintained when collapsing the topology, resulting in a visualization which is consistent with the original topology. We apply the collapsing topology technique to a turbulent flow field.
Extracting hydrographic objects from satellite images using a two-layer neural network

This paper presents a two-layer network for extracting hydrographic objects, such as rivers, from satellite images. The first layer is a locally connected network, which performs nonlinear smoothing. A unique property of the network is that the boundaries and junctions are presented with high accuracy while the noise within each region is greatly suppressed. A second layer is a locally excitatory globally inhibitory oscillator network (LEGION), which extracts the desired objects. The seeds of objects are selected separately. To find hydrographic objects, seed points are automatically identified from the original image, based on the assumption that water bodies are homogenous. Computationally, this approach is parallel and local and can be effectively implemented using hardware directly, the efficiency of which may provide a potential solution for real-time image processing. Experimental results using digital orthophoto images are provided.
Heritability of cooperative behavior in the trust game

Although laboratory experiments document cooperative behavior in humans, little is known about the extent to which individual differences in cooperativeness result from genetic and environmental variation. In this article, we report the results of two independently conceived and executed studies of monozygotic and dizygotic twins, one in Sweden and one in the United States. The results from these studies suggest that humans are endowed with genetic variation that influences the decision to invest, and to reciprocate investment, in the classic trust game. Based on these findings, we urge social scientists to take seriously the idea that differences in peer and parental socialization are not the only forces that influence variation in cooperative behavior.
A study of educational and career aspirations of Semarang freshmen universities, Indonesia

Using the Weidman (1989) Undergraduate Socialization model, the present study attempts toexamine the distinction between educational and career aspirations in public and privateuniversity freshman of Semarang, Indonesia. The correlation between the four dimensions ofindependent variables, student characteristics, parental socialization, significant others, andcollegiate experiences, and four dependent variables, educational aspirations, expecting aposition as a government employee, expecting a position as a private employee, and careeraspirations were analyzed.Data were collected through a survey distributed to 379 freshmen students from two public and two private universities, using a stratified sampling method to analyze data from each university. Data were analyzed using zero order correlations and multiple regressions analysis.For both public and private university students, almost all student characteristic variablesthat correlate with educational and career aspirations showed a significant positive effect, and the degree of its correlation for the public sample is greater than for the private counterpart.For both public and private university students, almost all parental socioeconomic statusindicated a positive significance for educational and career aspirations. For private students,there were some significant negative effects of parental encouragement, but, on the other hand,no significant negative effects appear on educational and career aspirations.All variable significant other for public university showed a positive effect on careeraspirations and some negative effects on three other dependent variables, while for the privateuniversity only one variable, significant other, showed a positive significant effect on careeraspirations and two variables had negative effects on expecting a position as a private employee.In the public university sample, almost all collegiate experiences variables that had acorrelation to educational and career aspirations showed significant positive effects. In addition,the relative absence of collegiate experiences for educational and career aspirations, especiallysocial integration, is somewhat contradictory to Weidman's model.Expecting a position as a government employee and expecting a position as private employee are new variables and were never used as criterion in the previous research on educational and career aspirations. However, it is not effective enough to employ in the model of educational and career aspirations.
Beyond ` 1 : Data Driven Sparse Signal Recovery using DeepInverse

We study a novel sparse signal recovery framework called DeepInverse that learns the inverse transformation from measurement vectors to signals using a deep convolutional network. We compare DeepInverse with `1-minimization from the phase transition point of view and demonstrate that it outperforms `1-minimization in the regions of phase transition plot where `1-minimization cannot recover the exact solution.
Memory retrieval and graphical passwords

Graphical passwords are an alternative form of authentication that use images for login, and leverage the picture superiority effect for good usability and memorability. Categories of graphical passwords have been distinguished on the basis of different kinds of memory retrieval (recall, cued-recall, and recognition). Psychological research suggests that leveraging recognition memory should be best, but this remains an open question in the password literature. This paper examines how different kinds of memory retrieval affect the memorability and usability of random assigned graphical passwords. A series of five studies of graphical and text passwords showed that participants were able to better remember recognition-based graphical passwords, but their usability was limited by slow login times. A graphical password scheme that leveraged recognition and recall memory was most successful at combining memorability and usability.
Influence of the Aln/Gan superlattices buffer thickness on the electrical properties of Algan/Gan HFET on Si substrate

The influence of the total thickness (periods of AlN/GaN SLs) of AlN/GaN superlattices (SLs) buffer on the static electrical properties of AlGaN/GaN HFETs is study for the purpose of improving device's breakdown voltage (BV) and reducing its on-resistance (R<inf>ON</inf>). It is found that for top-GaN layer with a constant thickness of lμm, a proper thickness of AlN/GaN SLs buffer (such as 2.5 μm with 100 period AlN/GaN SLs) could obtain better crystal quality of top-GaN layer as well as more robust devices with more superior performance in all aspects. The most robust HFETs in this work have achieved a specific on-resistance (R<inf>ON, SP</inf>) of 0.68 mΩ-cm<sup>2</sup> (@ L<inf>GD</inf>=4μm), a maximum on-state drain current (I<inf>D, max</inf>) of 430 mA/mm (@ L<inf>GD</inf>=4μm), an On/Off ratio of 2×10<sup>8</sup>, a BV of 552V at a drain leakage current of lμA/mm (@ L<inf>GD</inf>=15μm), and a figure-of-merit (FOM=BV<sup>2</sup>/R<inf>ON, SP</inf>) of 168 MW/cm<sup>2</sup> (@ L<inf>GD</inf>=8μm).
An antibody toolkit for the study of membrane traffic in Drosophila melanogaster

ABSTRACT The use of Drosophila melanogaster as a model organism has been pivotal to understanding the developmental processes of metazoans. However, the use of flies for studying subcellular organization is hampered by a paucity of reliable reagents to label specific organelles. Here, we describe the generation of mouse monoclonal antibodies against a set of markers of the secretory and endocytic pathways, along with goat polyclonal antibodies against two Golgi proteins. We show that the monoclonal antibodies are highly specific and sufficiently sensitive to detect endogenous proteins in crude extracts by immunoblotting with little background staining. By immunofluorescence the major compartments of the membrane traffic system (including the endoplasmic reticulum, the Golgi, and early and late endosomes) are labeled by at least one antibody. Moreover, the antibodies can be used to label organelles in fly tissues including salivary glands and wing imaginal discs. We anticipate that these antibodies will provide a useful tool kit to facilitate the investigation of how the endomembrane system functions and varies in the diverse tissue types of metazoans. Summary: We report the generation and characterization of set of monoclonal and polyclonal antibodies for labeling the major compartments of the secretory and endocytic pathways in Drosophila melanogaster.
Cytochrome P450 mono‐oxygenase‐regulated signalling of Ca2+ entry in human and bovine endothelial cells.

1. We tested the hypothesis that agonist‐stimulated Ca2+ entry, and thus formation of endothelium‐derived nitric oxide (EDNO) in vascular endothelial cells, is related to activation of microsomal P450 mono‐oxygenase (P450 MO) and the biosynthesis of 5,6‐epoxyeicosatrienoic acid (5,6‐EET). 2. Several P450 inhibitors diminished the sustained [Ca2+]i plateau response to agonist or intracellular Ca2+ store depletion with ATPase inhibitors by 31‐69% (fura‐2 technique). Mn2+ influx stimulated by agonists or ATPase inhibitors was prevented by P450 inhibitors. 3. Histamine‐ or ATPase inhibitor‐stimulated formation of EDNO was strongly attenuated (50‐83%) by P450 inhibitors, without any effect on EDNO formation by the Ca2+ ionophore A23187, indicating that decreased EDNO synthesis is due specifically to the inhibition of Ca2+ entry by these compounds. 4. Induction of P450 MO by beta‐naphthoflavone potentiated agonist‐induced Ca2+ and Mn2+ influx by 60 and 53%, respectively. Intracellular Ca2+ release remained unchanged. 5. The P450 MO product, 5,6‐EET (< 156 nmol l‐1), activated Ca2+/Mn2+ entry without any depletion of intracellular Ca2+ stores. The 5,6‐EET‐stimulated Ca2+/Mn2+ entry was not affected by P450 inhibitors. 6. As with the bradykinin‐stimulated Ca2+ entry pathway, the 5,6‐EET‐activated Ca2+ entry pathway was permeable to Mn2+ and Ba2+, sensitive to Ni2+, La3+ and membrane depolarization, and insensitive to the removal of extracellular Na+ or the organic Ca2+ antagonist, nitrendipine. 7. In the presence of 5,6‐EET, stimulation with bradykinin only transiently increased [Ca2+]i. Vice versa, 5,6‐EET failed to increase [Ca2+]i further in bradykinin‐stimulated cells. The sustained [Ca2+]i plateau phase induced by a co‐stimulation with bradykinin and 5,6‐EET was identical to that observed with bradykinin or 5,6‐EET alone. 8. These results demonstrate that Ca2+ entry induced by the P450 MO product, 5,6‐EET, is indistinguishable to that observed by stimulation with bradykinin. 9. All data support our hypothesis that depletion of endothelial Ca2+ stores activates microsomal P450 MO which in turn synthesizes 5,6‐EET. We propose that the arachidonic acid metabolite 5,6‐EET or one of its metabolites is a second messenger for activation of endothelial Ca2+ entry.
Sirolimus Improves Early Microcirculation, but Impairs Regeneration After Pancreatic Ischemia‐Reperfusion Injury

Ischemia and reperfusion injury remains a relevant problem in clinical pancreas transplantation. We investigated the effect of sirolimus (SRL) in a rodent model of 90‐min warm pancreatic ischemia. Four groups were studied: (1) sham surgery and vehicle; (2) sham surgery and SRL; (3) warm ischemia and vehicle; (4) warm ischemia and SRL. SRL (1.5 mg/kg/day) and vehicle were administered intraperitoneally for 3 days prior to surgery until the animals were killed. Microcirculation was assessed immediately after reperfusion by means of intravital fluorescence microscopy. Histopathological injury, apoptosis, proliferation and biochemical parameters were analyzed at 2 h, 1 day and 5 days after surgery. Ninety minutes after ischemia, intravital microscopy revealed an improved functional capillary density (p < 0.05) and reduction of adherent leucocytes (p < 0.01) and platelets (p < 0.05) in the SRL‐treated group compared to the vehicle‐treated controls. In contrast, on day 5 after ischemia, the pancreatic tissue of SRL‐treated animals showed a higher grade of histological injury (p < 0.05) and higher rate of apoptotic cells (p < 0.05) than the vehicle controls. In summary, our data indicate that administration of SRL improves microcirculation at a very early stage, but results in an impairment of the recovery phase after pancreatic ischemia‐reperfusion injury.
A 20 GS/s 1.2 V 0.13 $\mu\hbox{m}$ CMOS Switched Cascode Track-and-Hold Amplifier

A low voltage, low power, high sampling rate track-and-hold amplifier (THA) architecture is proposed. The THA samples at 20 GS/s and combines a distributed amplifier and a switched cascode stage. Power consumption for the circuit is 71 mW and it occupies 0.09 mm2 in 0.13 μm CMOS. The THA delivers up to 34 dB spur-free dynamic range (SFDR) and -32 dB total harmonic distortion (THD) at a supply voltage of 1.2 V. Input return loss remains below -10 dB over all frequencies of interest, while output return loss remains below -15 dB.
Transport discovery in wireless multi-transport environments

In order to utilize multiple transports, devices must discover common mechanisms for communication, a procedure we call multi-transport discovery. The multi-transport discovery algorithm presented in this paper is a four-phase procedure (transport probing, transport querying, address-to-device mapping, and transport accessibility) that can discover common transports within a multi-transport environment. Transport probing uses a transport-dependent device discovery mechanism to discover an initial link. Transport querying communicates over the probed link to query additional transports. Address-to-device mapping correctly correlates each transport to a remote device. Finally, transport accessibility periodically ascertains link availability during an application session.

The Upper Paleolithic represents both the phase during which anatomically modern humans appeared and the climax of hunter–gatherer cultures. Demographic expansion into new areas that took place during this period and the diffusion of burial practices resulted in an unprecedented number of well-preserved human remains. This skeletal record, dovetailed with ar-cheological, environmental, and chronological contexts, allows testing of hypotheses regarding biological processes at the population level. In this article, we review key studies about the biology of Upper Paleolithic populations based primarily on European samples, but integrating information from other areas of the Old World whenever possible. Data about cranial morphology, skeletal robusticity, stature, body proportions, health status, diet, physical activity, and genetics are evaluated in Late Pleistocene climatic and cultural contexts. Various lines of evidence delineate the Last Glacial Maximum (LGM) as a critical phase in the biological and cultural evolution of Upper Paleolithic populations. The LGM, a long phase of climatic deterioration culminating around 20,000 BP, had a profound impact on the environment, lifestyle, and behavior of human groups. Some of these effects are recorded in aspects of skeletal biology of these populations. Groups living before and after the LGM,
Discover whole part relationship between objects in video

This Paper develops a technique that efficiently discovers and analyzes the relationship between objects in captured video. The proposed framework detects and track the whole objects to extract temporal information from frame to frame which helps to find relation between objects by performing matching between objects in different frames. We use different techniques to implement these methods which were evaluated in order to assess how well they can detect moving regions, track objects and find relations. The final result of the algorithm is analyze by finding false positive and negative number of object detected which have relationship among each other in different frames.
The Removal of Homosexuality from the DSM: Its Impact on Today's Marriage Equality Debate

In 1973, the American Psychiatric Association (APA) removed homosexuality from its Diagnostic and Statistical Manual (DSM), leading to changes in the broader cultural beliefs about homosexuality and culminating in the contemporary civil rights quest for marriage equality. This paper reviews the history of theories about human sexuality that led up to that event and outlines the current sociopolitical environment in which marriage equality debates are taking place as well as the current state of marriage equality in the United States and elsewhere.
