Purpose In the United States, 3.8 million women have a history of breast (BC) or ovarian cancer (OC). Up to 15% of cases are attributable to heritable mutations, which, if identified, provide critical knowledge for treatment and preventive care. It is unknown how many patients who are at high risk for these mutations have not been tested and how rates vary by risk criteria. Methods We used pooled cross-sectional data from three Cancer Control Modules (2005, 2010, 2015) of the National Health Interview Survey, a national in-person household interview survey...

Utilizing data from 40 in-depth interviews, this article identifies both barriers and facilitators to colorectal screening guideline adherence among Appalachian Kentucky adults recruited through a community-based research network. Key findings identify (a) varying levels of knowledge about screening guidelines, (b) reticence to engage in screening processes, and (c) nuanced communication with healthcare providers and family members regarding screening adherence. What participants knew about the screening process was often derived from personal stories or recalled stories from family members about their screening experiences...

Epithelial-mesenchymal transition (EMT) can directly contribute to some malignant phenotypes of tumor cells including invasion, metastasis and resistance to chemotherapy. Although EMT is widely demonstrated to play a critical role in chemoresistance and metastasis, the potential signaling network between EMT and drug resistance is still unclear. The distribution of drugs in the internal and external environment of the tumor cells is tightly linked with ATP-binding cassette (ABC) transporters. Recent studies have shown that ABC transporters expression changed continuously during EMT...

BACKGROUND: The United Nations has called for countries to improve access to mobility devices when needed. The World Health Organization has published guidelines on the provision of manual wheelchairs in less-resourced settings. Yet little is known about the extent to which appropriate wheelchairs are available and provided according to international guidelines. This study's purpose was to describe wheelchair users' experiences receiving services and acquiring wheelchair skills in urban and peri-urban areas of Kenya and the Philippines...

There is a need for new, targeted smoking cessation interventions for smokers living with HIV. The Information-Motivation-Behavioral Skills (IMB) model has been applied effectively to HIV-related health behaviors and was used in this qualitative study to elicit factors that could lead to the development of innovative and successful cessation interventions for this population. Twenty individuals who smoked from two clinics providing care to people living with HIV participated in open-ended interviews, responding to questions covering the domains of the IMB model, as applied to smokers living with HIV...

OBJECTIVE: To explore risk perceptions, sexual practices and healthcare needs among men who have sex with men in the provincial city of Tanga in northern Tanzania. Previous research suggests that HIV/STIs are increasing problems for this population. Yet, few studies have been conducted outside the urban area of Dar es Salaam, which has limited our knowledge about the HIV/STI risk factors and healthcare needs among men who have sex with men who live outside major metropolitan areas. METHOD: During three months in 2013, 10 in-depth interviews with men who have sex with men were conducted in Tanga...

Many studies use population analysis approaches, such as dimensionality reduction, to characterize the activity of large groups of neurons. To date, these methods have treated each neuron equally, without taking into account whether neurons are excitatory or inhibitory. We studied population activity structure as a function of neuron type by applying factor analysis to spontaneous activity from spiking networks with balanced excitation and inhibition. Throughout the study, we characterized population activity structure by measuring its dimensionality and the percentage of overall activity variance that is shared among neurons...

Physician-scientists are individuals who actively participate in patient care, have undergone additional research training, and devote the majority of their time to research. Physician-scientists are traditionally the primary catalysts in bridging the translational gap-that is, the failure to link fundamental new knowledge in the pathobiology of disease with advances in health care and health policy in a timely manner. However, there has been a shift away from training physician-scientists, and financial support for the physician-scientist is diminishing globally, causing the translational gap to grow...

Ivan Salgado, Isaac Chairez
In this paper, a differential neural network (DNN) implemented as a robust observer estimates the dynamics of perturbed uncertain nonlinear systems affected by exogenous unknown inputs. In the first stage, the identification error converges into a neighborhood around the origin. Then, the second-order sliding mode supertwisting algorithm implemented as a robust exact differentiator reconstructed the unknown inputs. The approach proposed in this paper can be applied in the case of full access to the state vector (identification problem) and in the case of partial access to the state vector (estimation problem)...

J J Rodríguez-Rojas, E A Rebollar-Téllez
The aims of the study were to (a) investigate the effect of trapping methods on alpha diversity; and (b) enhance the knowledge of the sandfly assemblage in the state of Quintana Roo. Field work was undertaken in a tropical forest of southern Mexico from August 2013 to July 2014. Sampling was conducted monthly during three consecutive nights. For each trapping night, 12 different types of trap were operated from 18.00 to 24.00 hours in four transects. Measures of alpha community diversity were based on the quantification of the number of species (Chao 2, Jackknife 2, Clench's equation, Margalef's index) and the community structure, as well as the dominance (Simpson and Berger-Parker indexes) and evenness (Shannon's entropy index, true diversity of the Jost and Pielou index)...

OBJECTIVE: Mesial temporal lobe epilepsy (mTLE) is a severe neurological disorder characterized by recurrent seizures. mTLE is frequently accompanied by neurodegeneration in the hippocampus resulting in hippocampal sclerosis (HS), the most common morphological correlate of drug resistance in mTLE patients. Incomplete knowledge of pathological changes in mTLE+HS complicates its therapy. The pathological mechanism underlying mTLE+HS may involve abnormal gene expression regulation, including posttranscriptional networks involving microRNAs (miRNAs)...

Understanding how ecological and evolutionary processes interdependently structure biosphere dynamics is a major challenge in the era of worldwide ecosystem degradation. However, our knowledge of 'eco-evolutionary feedbacks' depends largely on findings from simple systems representing limited spatial scales and involving few species. Here we review recent conceptual developments for the understanding of multispecies coevolutionary processes and then discuss how new lines of concepts and methods will accelerate the integration of ecology and evolutionary biology...

BACKGROUND: Next-generation sequencing is widely used to identify disease-causing variants in patients with rare genetic disorders. Identifying those variants from whole-genome or exome data can be both scientifically challenging and time consuming. A significant amount of time is spent on variant annotation, and interpretation. Fully or partly automated solutions are therefore needed to streamline and scale this process. RESULTS: We describe Phenotype Driven Ranking (PDR), an algorithm integrated into Ingenuity Variant Analysis, that uses observed patient phenotypes to prioritize diseases and genes in order to expedite causal-variant discovery...

Cytokines are known to play important roles in a wide range of pathologic conditions spanning all organ systems in every species studied. As our knowledge of the physiology of individual cytokines expands and our ability to measure multiple cytokines in smaller biological samples increases, we gain more insight into the significance and function of each cytokine and the importance of cytokine networks. Previous studies that reported measurements of cytokine concentrations from serum or plasma in dogs with infectious, autoimmune, metabolic, endocrine, and neoplastic diseases yield an appreciation for the complexity of cytokine control and potential applications for cytokine measurements in the diagnosis, prognosis, and therapy of a variety of disease conditions...

Anterior patterning of animals is based on a set of highly conserved transcription factors but the interactions within the protostome anterior gene regulatory network (aGRN) remain enigmatic. Here, we identify the red flour beetle Tribolium castaneum ortholog of foxQ2 (Tc-foxQ2) as a novel upstream component of the aGRN. It is required for the development of the labrum and higher order brain structures, namely the central complex and the mushroom bodies. We reveal Tc-foxQ2 interactions by RNAi and heat shock-mediated misexpression...

The Cognitive Estimation Test (CET) is a widely used test to investigate estimation abilities requiring complex processes such as reasoning, the development and application of appropriate strategies, response plausibility checking as well as general knowledge and numeracy (e.g., Shallice and Evans, 1978; MacPherson et al., 2014). Thus far, it remains unknown whether the CET is both sensitive and specific to frontal lobe dysfunction. Neuroimaging techniques may not represent a useful methodology for answering this question since the complex processes involved are likely to be associated with a large network of brain regions, some of which are not functionally necessary to successfully carry out the CET...

This article is a personal account of my research in HIV prevention and how and why I navigated my way from social psychology to 'social health' via multidisciplinarity. My work in HIV prevention - from 1984 to the present day - developed my understandings of epistemology, building on and expanding the ways in which I undertook research. This article describes those whose writings and research influenced me and the input of colleagues and students. It also demonstrates my disquiet with the individualism of psychology as a way of thinking about what was needed to prevent HIV transmission...
