BACKGROUND: Patients with chronic kidney disease are at increased risk of cystic kidney disease that requires imaging monitoring in many cases. However, these same patients often have contraindications to contrast-enhanced computed tomography and magnetic resonance imaging. This study evaluates the accuracy of contrast-enhanced ultrasound (CEUS), which is safe for patients with chronic kidney disease, for the characterization of kidney lesions in patients with and without chronic kidney disease...

The Pig-a assay is being developed as an in vivo gene mutation assay for regulatory safety assessments. The assay is based on detecting mutation in the endogenous Pig-a gene of treated rats by using flow cytometry to measure changes in cell surface markers of peripheral blood cells. Here we present a methodology for demonstrating that phenotypically mutant rat T-cells identified by flow cytometry contain mutations in the Pig-a gene, an important step for validating the assay. In our approach, the mutant phenotype T-cells are sorted into individual wells of 96-well plates and expanded into clones...

A neural signature of asymptomatic preclinical Alzheimer's disease (AD) is disrupted connectivity between brain regions; however, its underlying mechanisms remain unknown. Here, we tested whether a preclinical pathologic feature, tau aggregation in the entorhinal cortex (EC) is sufficient to disrupt the coordination of local field potentials (LFPs) between its efferent regions. P301L-mutant human tau or green fluorescent protein (GFP) was virally overexpressed in the EC of adult rats. LFPs were recorded from the dorsal hippocampus and prelimbic medial prefrontal cortex while the rats underwent trace eyeblink conditioning where they learned to associate 2 stimuli separated by a short time interval...

INTRODUCTION: Eye injury is the second most common cause of visual impairment and a leading cause of monocular blindness in the United States. There are approximately 6 million ED visits related to drug use annually, including misuse or abuse of pharmaceuticals and illicit drug use. The purpose of this study was to assess the relationship between ocular trauma and substance abuse among emergency department patients and to assess that relationship with demographic factors, including age and gender...

Fanglue Lin, James K Tsuruta, Juan D Rojas, Paul A Dayton
Ultrasound contrast-enhanced super-resolution imaging has recently attracted attention because of its extraordinary ability to image vascular features much smaller than the ultrasound diffraction limit. This method requires sensitive detection of separable microbubble events despite a noisy tissue background to indicate the microvasculature, and any approach that could improve the sensitivity of the ultrasound system to individual microbubbles would be highly beneficial. In this study, we evaluated the effect of varying microbubble size on super-resolution imaging sensitivity...

Parenting group success begins with attendance. Using archival pilot data from 99 mothers who enrolled in the Mom Power (MP) parenting intervention, this study sought to understand the factors that influenced participant engagement and retention. MP is a group-based, early intervention program grounded in attachment theory that utilizes motivational interviewing as a core component to enhance program engagement. Study aims were to qualitatively describe the reasons why mothers were interested in participating in the program, including what they hoped to gain from the experience, and to quantitatively examine the extent to which attendance was associated with demographic, experiential, and psychosocial factors...

The extracellular microenvironment is an integral component of normal and diseased tissues that is poorly understood owing to its complexity. To investigate the contribution of the microenvironment to lung fibrosis and adenocarcinoma progression, two pathologies characterized by excessive stromal expansion, we used mouse models to characterize the extracellular matrix (ECM) composition of normal lung, fibrotic lung, lung tumors, and metastases. Using quantitative proteomics, we identified and assayed the abundance of 113 ECM proteins, which revealed robust ECM protein signatures unique to fibrosis, primary tumors, or metastases...

Objectives: We examined differences in depressive symptoms among people 65 and older who live alone, exploring whether these differences are associated with both health and environmental contexts. Method: Data are from the 2006 wave of Health Retirement Study (N = 2,956, age range: 65-104). We used a two-step cluster analytical approach to identify subgroups of health-limitation profiles and environmental profiles. Logistic regression models determined associations between subgroups and depressive symptoms...

Effective removal or dissolution of large blood clots remains a challenge in clinical treatment of acute thrombo-occlusive diseases. Here we report the development of an intravascular microbubble-mediated sonothrombolysis device for improving thrombolytic rate and thus minimizing the required dose of thrombolytic drugs. We hypothesize that a sub-megahertz, forward-looking ultrasound transducer with an integrated microbubble injection tube is more advantageous for efficient thrombolysis by enhancing cavitation-induced microstreaming than the conventional high-frequency, side-looking, catheter-mounted transducers...

The death-associated protein kinase 1 (DAPK1) is a potent mediator of neuronal cell death. Here, we find that DAPK1 also functions in synaptic plasticity by regulating the Ca(2+)/calmodulin (CaM)-dependent protein kinase II (CaMKII). CaMKII and T286 autophosphorylation are required for both long-term potentiation (LTP) and depression (LTD), two opposing forms of synaptic plasticity underlying learning, memory, and cognition. T286-autophosphorylation induces CaMKII binding to the NMDA receptor (NMDAR) subunit GluN2B, which mediates CaMKII synaptic accumulation during LTP...

Couplehood can be an important source of resilience in the face of memory loss, but couple identity has only recently been explored and has rarely been measured. This paper examines older spouses' descriptions of their couple identity and discusses salient themes. Data come from 19 couples from the Couples Life Story Project, a life review intervention where one partner has memory loss. Using baseline data, we analyzed how partners depicted their couple identity using a series of separate and overlapping circles...

Cancers of the pancreas have the poorest prognosis among all cancers, as many tumors are not detected until surgery is no longer a viable option. Surgical viability is typically determined via endoscopic ultrasound imaging. However, many patients who may be eligible for resection are not offered surgery due to diagnostic challenges in determining vascular or lymphatic invasion. In this paper, we describe the development of a dual-frequency piezoelectric transducer for rotational endoscopic imaging designed to transmit at 4 MHz and receive at 20 MHz in order to image microbubble-specific superharmonic signals...

BACKGROUND: Genetic and environmental factors contribute to the development of celiac disease (CD), but specific genetic predisposing factors remain poorly understood. One candidate is allele 2 of the hs1.2 enhancer within the immunoglobulin heavy chain region. In humans, there are four possible alleles and a previous study of an Italian cohort demonstrated a significantly increased frequency of allele 2 in patients with CD. AIMS: The purpose of the current study was to determine if a similar association between allele 2 and CD exists in an American population from Dayton, OH...

Childhood stunting, being short for one's age, has life-long consequences for health, human capital and economic growth. Being stunted in early childhood is associated with slower cognitive development, reduced schooling attainment and adult incomes decreased by 5-53%. The World Health Assembly has endorsed global nutrition targets including one to reduce the number of stunted children under five by 40% by 2025. The target has been included in the Sustainable Development Goals (SDG target 2.2). This paper estimates the cost of achieving this target and develops scenarios for generating the necessary financing...

Single Lgr5 intestinal stem cells (ISCs) can be expanded in vitro into epithelial organoids or "mini-guts", self-organizing cellular structures that recreate the intestinal differentiation program; Paneth cells, which constitute the intestinal stem cell niche, secrete stem cell growth signals, and are thus essential for this process. In a recent paper published in Nature, Rodríguez-Colman et al. describe how Paneth cells may be supporting the metabolic state of ISCs.

INTRODUCTION: Left atrial appendage (LAA) closure has become of major interest for patients with atrial fibrillation intolerant to oral anticoagulation therapy (OAC). Patients with a contraindication to both OAC and antiplatelet therapy are not eligible for percutaneous LAA closure. We aimed to find an alternative treatment for these specific patients. METHODS: From March 2014 until December 2015 five patients were referred for percutaneous LAA closure. Alternative treatment was necessary due to an absolute contraindication to OAC and antiplatelet therapy (n = 4) or after previous failed percutaneous device implantation (n = 1)...
