In many fruit species, including grapevine, grafting is used to improve scion productivity and quality and to adapt the plant to environmental conditions. However, the mechanisms underlying the rootstock control of scion development are still poorly understood. The ability of rootstocks to regulate nitrogen uptake and assimilation may contribute to this control. A split-root system was used to grow heterografted grapevines and to investigate the molecular responses to changes in nitrate availability of two rootstocks known to affect scion growth differently...

BACKGROUND: Patients with longstanding ulcerative colitis and colonic Crohn's disease have an increased risk of colorectal cancer (CRC) compared with the general population. This review assessed the evidence that endoscopic surveillance may prolong life by allowing earlier detection of CRC or its pre-cursor lesion, dysplasia, in patients with inflammatory bowel disease (IBD). OBJECTIVES: To assess the effectiveness of cancer surveillance programs for diagnosis of IBD-associated colorectal cancer and in reducing the mortality rate from colorectal cancer in patients with IBD...

High-quality data analysis methodology remains a bottleneck for metabolic profiling analysis based on ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry. The present work aims to address this problem by proposing a novel data analysis strategy wherein (1) chromatographic peaks in the UPLC-QTOF dataset are automatically extracted by using an advanced multiscale Gaussian smoothing-based peak extraction strategy. (2) A peak annotation stage is used to cluster fragment ions that belong to the same compound...

Chronic wounds affect 12-15% of patients with diabetes and are associated with a drastic decrease in their quality of life. Here we demonstrate that purified mature naïve B220(+) /CD19(+) /IgM(+) /IgD(+) B cells improve healing of acute and diabetic murine wounds after a single topical application. B cell treatment significantly accelerated acute wound closure by 2-3 days in wild-type mice and 5-6 days in obese diabetic mice. The treatment led to full closure in 43% of chronic diabetic wounds, as compared to only 5% in saline-treated controls...

This study aims to understand the role that optimism could play in the context of a health asset approach to promote adolescent health-related quality of life (HRQOL). Adolescents (n = 948), between 11 and 16 years old from a medium-sized rural town in Sweden, answered questionnaires measuring optimism, pessimism, and HRQOL. The findings indicate a significant decrease in optimism and a significant increase in pessimism between early and midadolescence. The study has allowed us to present associational evidence of the links between optimism and HRQOL...

The ovarian follicle encloses oocytes in a microenvironment throughout their growth and acquisition of competence. Evidence suggests a dynamic interplay among follicular cells and oocytes, since they are constantly exchanging "messages". We dissected bovine ovarian follicles and recovered follicular cells (FCs-granulosa and cumulus cells) and cumulus-oocyte complexes (COCs) to investigate whether the PI3K-Akt signaling pathway impacted oocyte quality. Following follicle rupture, COCs were individually selected for in vitro cultures to track the follicular cells based on oocyte competence to reach the blastocyst stage after parthenogenetic activation...

INTRODUCTION: Although ANC services are increasingly available to women in low and middle-income countries, their inadequate use persists. This suggests a misalignment between aims of the services and maternal beliefs and circumstances. Owing to the dearth of studies examining the timing and adequacy of content of care, this current study aims to investigate the timing and frequency of ANC visits in Ethiopia. METHODS: Data was obtained from the nationally representative 2011 Ethiopian Demographic and Health Survey (EDHS) which used a two-stage cluster sampling design to provide estimates for the health and demographic variables of interest for the country...

BACKGROUND: There is a significantly high rate of work-related musculsokeletal injuries in sonography professionals. To date, assessment of risk factors for work- related injuries in sonographers has been based primarily on surveys, subjective reports, and observational methods. There is a need to develop quantitative techniques to better understand risk factors and develop preventive interventions. OBJECTIVE: We pilot tested a high-resolution force-measuring probe capable of precisely measuring forces applied through the transducer by sonographers and used this novel direct measurement technique to evaluate forces during abdominal imaging...

Jizhou Li, Florian Luisier, Thierry Blu
We propose a non-iterative image deconvolution algorithm for data corrupted by Poisson or mixed Poisson-Gaussian noise. Many applications involve such a problem, ranging from astronomical to biological imaging. We parametrize the deconvolution process as a linear combination of elementary functions, termed as linear expansion of thresholds (LET). This parametrization is then optimized by minimizing a robust estimate of the true mean squared error, the Poisson unbiased risk estimate (PURE). Each elementary function consists of a Wiener filtering followed by a pointwise thresholding of undecimated Haar wavelet coefficients...

Knowledge of the microbiological quality and prevalence of antibiotic resistance and virulence genes in bacterial isolates from leafy green vegetables supplied by formal suppliers (retailers) and informal suppliers (street vendors) in South Africa is limited. Because leafy vegetables have been implicated in foodborne disease outbreaks worldwide, 180 cabbage and spinach samples were collected from three major retailers and nine street vendors in Johannesburg, South Africa. Escherichia coli and coliforms were enumerated using Petrifilm plates...

Countertransference is an important aspect of the therapeutic relationship that exists in therapies of all theoretical orientations, and depending on how it is managed, it can either help or hinder treatment. Management of countertransference has been measured almost exclusively with the Countertransference Factors Inventory (Van Wagoner, Gelso, Hayes, & Diemer, 1991) and its variations, all of which focus on 5 therapist qualities theorized to facilitate management: self-insight, conceptualizing ability, empathy, self-integration, and anxiety management...

Cholestatic liver diseases (CLDs) encompass a variety of disorders of bile formation and/or flow which generally result in progressive hepatobiliary injury and ultimately end-stage liver disease. Many patients with CLD are diagnosed between the ages of 20-50 years, a particularly productive period of life professionally, biologically, and in other respects; it is not surprising, thus, that CLD is often associated with impaired health-related quality of life (HRQOL) and uncertainty regarding implications for and outcomes of pregnancy...
