DEPArray™ system: An automatic image-based sorter for isolation of pure circulating tumor cells.

Cytometry A 2018 Dec;93(12):1260-1266

Menarini Silicon Biosystems S.p.A, Bologna, Italy.

Circulating tumor cells (CTCs) are rare cells shed into the bloodstream by invasive tumors and their analysis offers a promising noninvasive tool to predict and monitor therapeutic responses. CTCs can be isolated from patient blood and their characterization at single-cell level can inform on the genomic landscape of a tumor. All CTC enrichment methods bear a burden of contaminating normal cells, which mandate a further step of purification to enable reliable downstream genetic analysis. Read More

Department of Pediatrics, Sendai Medical Center, 2-8-8 Miyagino, Sendai 983-8520, Japan.

Background: Kawasaki disease (KD) is an acute, systemic vasculitis syndrome that occurs in children. The clinical symptoms and epidemiological features of KD strongly suggest that KD is triggered by unidentified infectious agents in genetically predisposed patients. In addition, a number of studies have described the role of B cells in the development of KD. Read More

Impact of High Fat Diet on Vasoconstrictor Reactivity of White and Brown Adipose Tissue Resistance Arteries.

Am J Physiol Heart Circ Physiol 2018 Dec 14. Epub 2018 Dec 14.

Internal Medicine-Division of Geriatrics, University of Utah, United States.

Blood flow regulation is a critical factor for tissue oxygenation and substrate supply. Increased reactivity of arteries to vasoconstrictors may increase vascular resistance, resulting in reduced blood flow. Here, we aimed to investigate the effect of high fat (HF) diet on stiffness and vasoconstrictor reactivity of white and brown adipose tissue (WAT and BAT) resistance arteries and also investigated the interconversion of both the adipose depots during HF diet condition.

Losartan prevents the elevation of blood pressure in adipose-PRR deficient female mice while elevated circulating sPRR activates the renin angiotensin system.

Am J Physiol Heart Circ Physiol 2018 Dec 14. Epub 2018 Dec 14.

Graduate Center for Nutritional Sciences, University of Kentucky, United States.

The deletion of the prorenin receptor (PRR) in adipose tissue elevates systolic blood pressure (SBP) and circulating soluble form of PRR (sPRR) in male mice fed a high-fat diet (HF). However, sex differences in the contribution of adipose-PRR and sPRR to the regulation of the renin-angiotensin system (RAS) in key organs for blood pressure control are undefined. Therefore, we assessed blood pressure and the systemic and intrarenal RAS status in adipose-PRR KO female mice. Read More

Eating pathology and psychological outcomes in young adults in self-regulation interventions using daily self-weighing.

Health Psychol 2018 Dec 13. Epub 2018 Dec 13.

Warren Alpert Medical School.

Objective: Self-regulation interventions encouraging daily weighing prevent weight gain in young adults; however, concerns have been raised that such interventions may have undesirable effects on eating pathology, depression, and health-related quality of life (HRQL). The present study examined whether self-regulation interventions and self-weighing frequency were associated with these indices in normal weight individuals and those with overweight or obesity.

Methods: Young adults ( = 599), 18-35 years with a body mass index (BMI) 21. Read More

Age differences in everyday stressor-related negative affect: A coordinated analysis.

Psychol Aging 2018 Dec 13. Epub 2018 Dec 13.

Department of Biobehavioral Health and Medicine.

Advancing age is often characterized by preserved or even enhanced emotion regulation, which is thought to manifest in terms of age-related reductions in the within-person association between stressors and negative affect. Existing research from ecological momentary assessment and end-of-day daily diary studies examining such age-related benefits have yielded mixed results, potentially due to differences in samples, design, and measurement of everyday stressors and negative affect. We conducted a coordinated analysis of 5 ecological momentary assessments and 2 end-of-day daily diary studies to examine adult age differences in the within-person association between everyday stressors and negative affect.

A Special Risk Group for Hepatitis E Infection: The First Record of North Cyprus.

Pol J Microbiol 2018 ;67(4):525-528

Department of Biophysics, Faculty of Medicine, Near East University , Nicosia , Cyprus.

Hepatitis E virus (HEV) is transmitted by a fecal oral route from animals to humans following exposure to the body fluids of infected animals. We investigated the seroprevalence of anti-hepatitis E (anti-HEV) antibodies by monitoring IgG and IgM virus antibodies amongst employees in the animal industry in North Cyprus through a cross-sectional study. Samples were taken from individuals without occupational exposure to animals and from those who worked with animals (doing animal husbandry, veterinary work or butchery). Read More
