Planar cell polarity (PCP)-signaling and associated tissue polarization are evolutionarily conserved. A well documented feature of PCP-signaling in vertebrates is its link to centriole/cilia positioning, although the relationship of PCP and ciliogenesis is still debated. A recent report in Drosophila established that Frizzled (Fz)-PCP core signaling has an instructive input to polarized centriole positioning in non-ciliated Drosophila wing epithelia as a PCP read-out. Here, we review the impact of this observation in the context of recent descriptions of the relationship(s) of core Fz-PCP signaling and cilia/centriole positioning in epithelial and non-epithelial cells...

This study qualitatively examined rural emerging adults' ways of thinking (i.e., lay theories) about the causes of intimate partner violence (IPV) and ideas on how to prevent IPV most effectively. Participants were 74 individuals (majority Caucasian, heterosexual, low income) between the ages of 18 and 24 who resided in one of 16 rural communities. Participants' perceptions of the causes of IPV included (a) individual-level pathology, stress, and lack of education; (b) intergenerational transmission of violence and early-life factors; (c) relationship stressors and challenges; and (d) community factors...

PURPOSE: The prevalence of intimacy and substance use among adolescents and young adults during cancer therapy has not been well described. METHODS: The "Resilience in Adolescents and Young Adults with Cancer" study was a prospective, multicenter, mixed-methods cohort study. English-speaking patients 14-25 years old with newly diagnosed cancer were invited to complete a comprehensive survey at the time of enrollment (T1) and 3-6 months later (T2). Intimate relationships and health behaviors were assessed with questions adapted from the Guidelines for Adolescent Preventative Services assessment...

Microbial communities contain diverse bacteria that play important roles in every environment. Advances in sequencing and computational methodologies over the past decades have illuminated the phylogenetic and functional diversity of microbial communities from diverse habitats. Among the activities encoded in microbiomes are the abilities to synthesize and resist small molecules, yielding antimicrobial activity. These functions are of particular interest when viewed in light of the public health emergency posed by the increase in clinical antimicrobial resistance and the dwindling antimicrobial discovery and approval pipeline, and given the intimate ecological and evolutionary relationship between antimicrobial biosynthesis and resistance...

The mammalian gastrointestinal tract has co-developed with a large number of microbes in a symbiotic relationship over millions of years. Recent studies indicate that indigenous bacteria are intimate with the intestine and play essential roles in health and disease. In the quest to maintain a stable niche, these prokaryotes influence multiple host metabolic pathways, resulting from an interactive host-microbiota metabolic signaling and impacting strongly on the metabolic phenotypes of the host. Since dysbiosis of the gut bacteria result in alteration in the levels of certain microbial and host co-metabolites, identifying these markers could enhance early detection of diseases...

Traumatic brain injury (TBI) in women experiencing intimate-partner violence (IPV) is common, and IPV afflicts 30 % of women worldwide. However, the neurobiology and related sequelae of these TBIs have never been systematically examined. Consequently, TBI treatments are typically absent and IPV interventions are inadequate. There has been a call for a comprehensive assessment of IPV-related TBIs and their relationship to aspects of women's cognitive and neural functioning. In response, we examined brain-network organization associated with TBI and its cognitive effects using clinical interviews and neuropsychological measures as well as structural and functional Magnetic Resonance Imaging (fMRI) in women experiencing IPV-related TBI...

INTRODUCTION: Patient-reported outcome measures are increasingly utilized in dermatology to assess the impact of skin disease on quality of life. Despite recognition of the influence of skin disease on intimate relationships, an instrument to assess intimacy has not been developed. The objective of this study was to create the Dermatologic Intimacy Scale (DIS) and administer the prototype to a patient population. METHODS: A group of healthcare providers at the University of California San Francisco created the DIS prototype...

Today, nurses are confronted with much more in their day-to-day activities than 40 years ago. Not only are nurses caring for more patients during their shifts, patients are acute and complex and have shorter hospital stays. The nurse-patient relationship has been a focus of nursing since the profession began. Nurses today engage with vulnerable individuals in intimate and highly technical environments. Not only do nurses care for people using highly technical skills, but also nurses educate and support individuals toward healing by listening, and encouraging people toward improved health...

URu2Si2 is one of the most enigmatic strongly correlated electron systems and offers a fertile testing ground for new concepts in condensed matter science. In spite of >30 years of intense research, no consensus on the order parameter of its low-temperature hidden-order phase exists. A strong magnetic field transforms the hidden order into magnetically ordered phases, whose order parameter has also been defying experimental observation. Here, thanks to neutron diffraction under pulsed magnetic fields up to 40 T, we identify the field-induced phases of URu2Si2 as a spin-density-wave state...

Research that simultaneously examines the relationship of multiple types of family and community violence with youth outcomes is limited in the previous research literature, particularly in Latin America. This study examined the relationship of youth exposure to family and community violence-parental use of corporal punishment, violence in the community, intimate partner physical aggression-with eight subscales of the Youth Self Report among a Chilean sample of 593 youth-mother pairs. Results from multilevel models indicated a positive association between youth exposure to violence in the family and community, and a wide range of behavior problem outcomes, in particular, aggression...

AIMS: Conventional computed tomography (CT) approaches provides limited visualization of the entire endoluminal changes of aortic dissection (AD), which is essential for its treatment. As an important supplement, three-dimensional CT virtual intravascular endoscopy (VIE) can show relevant details. This study aims to determine the value of VIE in displaying the entry tear and intimal flap of AD. METHODS AND RESULTS: Among 127 consecutive symptomatic patients with suspected AD who underwent CT angiography (CTA), 84 subjects were confirmed to have AD and were included in the study...

BACKGROUND: The association between alcohol consumption and intimate partner violence (IPV) has been reiterated in numerous studies. Some authors have found higher levels of risk factors in intimate partner violence offenders (IPVOs) with alcohol problems than in IPVOs without such problems. OBJECTIVE: The aim of this study is to analyze the relationship of contextual variables with harmful alcohol use in a sample of IPVOs. METHOD: This cross-sectional research analyzes data from 231 IPVOs...

Much cross-sectional research documented associations between sexuality and life satisfaction, but very little longitudinal research on the topic has considered whether changes in sexuality and life satisfaction unfold together over time. Using data from 5582 individuals in partnerships surveyed across 5786 intimate relationships (providing 18,712 observations for analysis) during five waves of the German Family Panel (pairfam), this study examined whether intraindividual changes in sexual frequency and satisfaction were associated with corresponding intraindividual changes in life satisfaction...

Blood vessels function as conduits for distribution of blood throughout the circulatory system. Large arteries, in addition to the essential conduit function, also serve to dampen the effect of pulsatile ventricular ejection that generates pulsatile pressure with each cardiac cycle; that is, they exhibit a 'cushion' function. The conduit function can be compromised by intimal effects that cause obstruction to flow, generally attributed to plaque formation due to intimal changes affected by atherosclerotic processes...

Childhood exposure to intimate partner violence (IPV) results in numerous, lifelong, negative health outcomes, underscoring the American Academy of Pediatrics' recommendation for IPV screening and intervention in the pediatric health care setting. We report a case in which a mother denied IPV during routine IPV screening in a pediatric emergency department (ED). However, subsequent discussion with health care providers during the ED visit revealed IPV. The mother declined to meet with an IPV advocate because the abuser was texting repeatedly to ask about the duration of the ED visit...

BACKGROUND: Contextual factors, such as exposure to stressors, may be antecedents to IPV perpetration. These contextual factors may be amenable to modification through intervention and prevention. However, few studies have examined specific contextual factors. To begin to address this gap, we examined the associations between financial stressors and three types of physical IPV perpetration. METHODS: This analysis used data from Wave IV of The National Longitudinal Study of Adolescent to Adult Health...

The virulence of highly pathogenic bacteria such as Salmonella, Yersinia, Staphylococci, Clostridia, and pathogenic strains of Escherichia coli involves intimate cross-talks with the host actin cytoskeleton and its upstream regulators. A large number of virulence factors expressed by these pathogens modulate Rho GTPase activities either by mimicking cellular regulators or by catalyzing posttranslational modifications of these small proteins. This impressive convergence of virulence toward Rho GTPases and actin indeed offers pathogens the capacity to breach host defenses and invade their host, while it promotes inflammatory reactions...

Reactive oxygen species (ROS) play a key role in the regulation of many biological processes in plants. Nonetheless, they are considered highly reactive and toxic to cells. Owing to their toxicity, as well as their important role in signaling, the level of ROS in cells needs to be tightly regulated. The ROS gene network, encoding a highly redundant arsenal of ROS scavenging mechanisms and an array of enzymes involved in ROS production, regulates ROS metabolism and signaling in plants. In this article, we review the role of the ROS gene network in plants and examine how it evolved...

A comprehensive understanding of the normal and abnormal aortic root is paramount if we are to improve not only our assessment of the aortic root and its components but also the surgical approach to reconstructing this complex structure when congenitally malformed. Most anatomic and imaging-based classifications of the normal root recognize and describe the basic components, which include the shape and size of the three aortic sinuses and their three valvar leaflets, as well as the sinutubular junction and proximal ascending aorta...
