Ultrasound Monitoring of Extant Adnexal Masses in the Era of Type 1 and Type 2 Ovarian Cancers: Lessons Learned From Ovarian Cancer Screening Trials

Women that are positive for an ovarian abnormality in a clinical setting can have either a malignancy or a benign tumor with probability favoring the benign alternative. Accelerating the abnormality to surgery will result in a high number of unnecessary procedures that will place cost burdens on the individual and the health delivery system. Surveillance using serial ultrasonography is a reasonable alternative that can be used to discover if changes in the ovarian abnormality will occur that favor either a malignant or benign interpretation. Several ovarian cancer screening trials have had extensive experiences with changes in subclinical ovarian abnormalities in normal women that can define growth, stability or resolution and give some idea of the time frame over which changes occur. The present report examines these experiences and relates them to the current understanding of ovarian cancer ontology, presenting arguments related to the benefits of surveillance

Eliminating helper phage from phage display

Phage display technology involves the display of proteins or peptides, as coat protein fusions, on the surface of a phage or phagemid particles. Using standard technology, helper phage are essential for the replication and assembly of phagemid particles, during library production and biopanning. We have eliminated the need to add helper phage by using 'bacterial packaging cell lines' that provide the same functions. These cell lines contain M13-based helper plasmids that express phage packaging proteins which assemble phagemid particles as efficiently as helper phage, but without helper phage contamination. This results in genetically pure phagemid particle preparations. Furthermore, by using constructs differing in the form of gene 3 that they contain, we have shown that the display, from a single library, can be modulated between monovalent (phagemid-like) and multivalent display (phage-like) without any further engineering. These packaging cells eliminate the use of helper phage from phagemid-based selection protocols; reducing the amount of technical preparation, facilitating automation, optimizing selections by matching display levels to diversity, and effectively using the packaged phagemid particles as means to transfer genetic information at an efficiency approaching 100%

Student Modeling Based on Fine-Grained Programming Process Snapshots

ICER '17 Proceedings of the 2017 ACM Conference on International Computing Education Research. New York, NY, USA : ACM, 2017 ISBN: 978-1-4503-4968-0I am studying the use of fine-grained programming process data for student modeling. The initial plan is to construct different types of program state representations such as Abstract Syntax Trees (ASTs) from the data. These program state representations could be used for both automatically inferring knowledge components that the students are trying to learn as well as for modeling students' knowledge on those specific components.Peer reviewe

IS900 Restriction Fragment Length Polymorphism (RFLP) Analysis of Mycobacterium avium subsp. paratuberculosis Isolates from Goats and Cattle in Norway

In Norway, paratuberculosis has been frequently diagnosed in goats, while cattle have been almost free of the infection. This difference in prevalence between goats and cattle has led to speculations about the existence of a Mycobacterium avium subsp. paratuberculosis (M. a. paratuberculosis) isolate that is non-pathogenic for cattle. There is little information available on genotypic variation of M. a. paratuberculosis isolated from animals in Norway. In the present study, genotypic information on 51 isolates from goats and four isolates from cattle in Norway was obtained by use of IS900 restriction fragment length polymorphism (RFLP) analysis. All isolates from cattle and 84% of the isolates from goats had the same RFLP pattern (B-C1). Five RFLP patterns not previously detected were found. No genotypic variation that could explain a difference in host origin was found between the isolates from cattle and the majority of the Norwegian goat isolates. This lack of difference indicates that the most common M. a. paratuberculosis isolates in Norway may infect both cattle and goats

The effect of moderate weight loss on echocardiographic parameters in obese female patients

Based on the data collected by KNOLL Hungary Ltd. in Hungary in 1999, 37% of the adult population is overweight while 23% is obese. Inappropriate diet containing excess calories and physical inactivity are responsible for these statistical values. In their former studies, the authors investigated the effects of different stages of obesity on the cardiovascular system, and have verified that even moderate obesity elicits pathological geometric and functional changes in the heart. In the present study, effect of a half-year-long life-style modification program on the morphologic and functional characteristics of the heart was investigated in twenty-one obese women. Life-style modification contained a diet with reduced energy uptake (1000–1300 Cal/day) and a regular physical training of minimum 3–4 hours weekly. By the end of the sixth month the weight loss was 5.1 kg (5.9%) on an average. There was a marked reduction in cardiac dimensions measured by echocardiography, with a very slight, non-significant decrease in left ventricular internal diameter, and a marked, significant reduction in the left ventricular wall thickness. Decrease of the left ventricular muscle mass exceeded the decrease of body weight. A marked elevation was found in the E/A quotient that reflected a definite improvement in diastolic function. Results indicate that physical training programs have a favourable effect on the echocardiographic parameters, therefore the process is reversible even without a pharmacological intervention

Prenatal Alcohol Exposure and Placental Insufficiency Results in Reduced Neuronal Complexity in the Rat Prefrontal Cortex

Prenatal Alcohol Exposure (PAE) can produce long-term neurodevelopmental deficits and impaired executive function. Alcohol exposure during gestation is associated with impaired fetal development caused by placental insufficiency. The impact following PAE and placental insufficiency (PI) remains unknown. Utilizing a three-dimensional (3D) Sholl analysis, we hypothesized that PAE+PI will result in decreased neuronal complexity within the frontal cortex, a region critical to executive functioning. Pregnant Long-Evans rats voluntarily drank 5% ethanol or saccharin water until embryonic day 18 (E18) to mimic moderate PAE. On E19, a laparotomy was performed to occlude the uterine artery for 60 minutes to induce PI. The pups delivered normally. At postnatal day 100 (P100), brains were extracted and Golgi-Cox stained. Coronal sections were imaged utilizing a Leica TCS SP8 Confocal microscope with z-stacking capabilities. A 3D Sholl analysis was conducted within Imaris software to assess variance in neural complexity between treatment groups. Analysis was completed with a 2-way ANOVA and t-test. Five PAE+PI and 5 control brains were collected. In the medial frontal cortex, 3 neurons were analyzed from each hemisphere. No statistical difference was noted between the two hemispheres, so the data was combined for each animal resulting in 6 neurons being analyzed. The proximal dendritic complexity was similar between groups. PAE+PI resulted in significantly diminished complexity more distal from the soma; at 80 mm the PAE+PI group had an average of 2.4 intersections while the control group had an average of 3.3 (p\u3c0.05). At 90 mm, the PAE+PI group continued to have fewer intersections compared to controls (1.8 vs. 2.6). This is the first study to investigate the dendritic complexity following PAE combined with PI within the frontal cortex. Given the importance of this region to executive function, this may provide insight into the long-term deficits that are observed and provide support for interventions

Media justice: Madeleine McCann, intermediatization and "trial by media" in the British press

Three-year-old Madeleine McCann disappeared on 3 May 2007 from a holiday apartment in Portugal. Over five years and multiple investigations that failed to solve this abducted child case, Madeleine and her parents were subject to a process of relentless ‘intermediatization’. Across 24–7 news coverage, websites, documentaries, films, YouTube videos, books, magazines, music and artworks, Madeleine was a mediagenic image of innocence and a lucrative story. In contrast to Madeleine’s media sacralization, the representation of her parents, Kate and Gerry McCann, fluctuated between periods of vociferous support and prolonged and libellous ‘trial by media’. This article analyses how the global intermediatization of the ‘Maddie Mystery’ fed into and fuelled the ‘trial by media’ of Kate and Gerry McCann in the UK press. Our theorization of ‘trial by media’ is developed and refined through considering its legal limitations in an era of ‘attack journalism’ and unprecedented official UK inquiries into press misconduct and criminality

Defining the gap between research and practice in public relations programme evaluation - towards a new research agenda

The current situation in public relations programme evaluation is neatly summarized by McCoy who commented that 'probably the most common buzzwords in public relations in the last ten years have been evaluation and accountability' (McCoy 2005, 3). This paper examines the academic and practitioner-based literature and research on programme evaluation and it detects different priorities and approaches that may partly explain why the debate on acceptable and agreed evaluation methods continues. It analyses those differences and proposes a research agenda to bridge the gap and move the debate forward
