Inferring the absence of an incipient population during a rapid response for an invasive species.

Successful eradication of invasives is facilitated by early detection and prompt onset of control. However, realizing or verifying that a colonization has occurred is difficult for cryptic species especially at low population densities. Responding to the capture or unconfirmed sighting of a cryptic invasive species, and the associated effort to determine if it indicates an incipient (small, localized) population or merely a lone colonizer, is costly and cannot continue indefinitely. However, insufficient de...

A collaborative computer aided diagnosis (C-CAD) system with eye-tracking, sparse attentional model, and deep learning.

Computer aided diagnosis (CAD) tools help radiologists to reduce diagnostic errors such as missing tumors and misdiagnosis. Vision researchers have been analyzing behaviors of radiologists during screening to understand how and why they miss tumors or misdiagnose. In this regard, eye-trackers have been instrumental in understanding visual search processes of radiologists. However, most relevant studies in this aspect are not compatible with realistic radiology reading rooms. In this study, we aim to develop...

The ipsilesional attention bias in right-hemisphere stroke patients as revealed by a realistic visual search task: Neuroanatomical correlates and functional relevance.

Right-hemisphere stroke may cause an ipsilesional attention bias and left hemispatial neglect. Computerized time-limited tasks are more sensitive than conventional paper-pencil tests in detecting these spatial attention deficits. However, their frequency in the acute stage of stroke, the neuroanatomical basis and functional relevance for patients' everyday life are unclear.

The search of "canonical" explanations for the cerebral cortex.

This paper addresses a fundamental line of research in neuroscience: the identification of a putative neural processing core of the cerebral cortex, often claimed to be "canonical". This "canonical" core would be shared by the entire cortex, and would explain why it is so powerful and diversified in tasks and functions, yet so uniform in architecture. The purpose of this paper is to analyze the search for canonical explanations over the past 40 years, discussing the theoretical frameworks informing this re...

The use of the functional state of the joints for the estimation of the effectiveness of the application of oxygen/ozone therapy for the rehabilitative treatment of the patients suffering from knee arthritis.

In the recent years, the ever increasing tendency toward the growth in the prevalence of degenerative-dystrophic articular diseases has been observed especially among the young subjects and the middle-aged people. The enhanced economic burden of treating the patients with this condition on the public health care system frequently comes not only from chronic pathology of the joints but also from the development of concomitant disorders which dictates the necessity of the search for the new methods for the ma...

This critical review explores the (i) oral physiology of a baby nursing (ii) factors that can decrease a baby's ability to nurse efficiently, the problems these cause and their management and the (iii) relation between poor nursing efficacy and the risk of early childhood caries (ECC) Study design: An expansive search of the literature was performed using...

Capillary Electrophoresis (CE) vs. HPLC in the determination of asialo-Tf, a crucial marker for the reliable interpretation of questioned CDT increases.

CDT is a collective biomarker including asialo- and disialo-Tf, but researchers have generally focused attention on disialo-Tf, because of its easier detectability, since asialo-Tf is typically not detectable by the current methods in abstinent individuals, social drinkers and in many alcohol abusers with moderate CDT increases. In the search of a confirmation marker of alcohol-related CDT increases, the detectability of asialo-Tf was re-evaluated comparatively by using CE vs. HPLC.

Serum free light chains for monitoring systemic lupus erythematosus activity.

Introduction: Systemic lupus erythematosus (SLE) is an autoimmune disease leading to chronic inflammation of numerous tissues and organs. The search for clinically useful markers of its activity is ongoing. At present, it is suggested that serum free light chains (FLC) may be useful in assessing SLE activity. The aim of study: To investigate the relationship between serum levels of free light chains (FLC) and the activity of SLE.

In search of constrained FTY720 and phytosphingosine analogs as dual acting anticancer agents targeting metabolic and epigenetic pathways.

A series of compounds containing pyrrolidine and pyrrolizidine cores with appended hydrophobic substituents were prepared as constrained analogs of FTY720 and phytosphingosine. The effect of these compounds on the viability of cancer cells, on downregulation of the nutrient transport systems, and on their ability to cause vacuolation was studied. An attempt to inhibit HDACs with some phosphate esters of our analogs was thwarted by our failure to reproduce the reported inhibitory action of FTY720-phosphate.

Static Rope Evacuation by Helicopter Emergency Medical Services in Rescue Operations in Southeast Norway.

Physician-staffed helicopter emergency medical services (HEMS) in Norway are an adjunct to existing search and rescue services. Our aims were to study the epidemiological, operational, and medical aspects of HEMS daylight static rope operations performed in the southeastern part of the country and to examine several quality dimensions that are characteristic of this service.

Scoping review of systematic review abstracts about temporomandibular disorders: Comparison of search years 2004 and 2017.

The purposes of this study were to determine how many systematic reviews and meta-analyses relating to temporomandibular disorders (TMDs) had been published as of 2017 compared with those published as of 2004 and then to summarize the findings, based on an analysis of the abstracts from those studies.

Prepared for the Unexpected: Accessory Ovaries with Abernethy Malformation.

Supernumerary and accessory ovaries are collectively coined ectopic ovaries. These are rarely encountered by the benign gynecologist, and are often discovered incidentally during evaluation for other gynecologic, gastrointestinal or urologic pathologies. We report the presentation of a patient with multiple accessory ovaries in addition to a rare congenital anomaly of the splanchnic vasculature called an Abernethy malformation. Incidental identification of ectopic ovaries necessitates a search for additiona...

The analysis of the pathogenetic factors for the psychosocial maladaptation formation in patients with alcohol dependence.

Introduction: The search for early diagnostic markers of the psychosocial maladaptation formation in alcohol dependence to optimize the treatment, rehabilitation and preventive measures in this cohort of patients is one of the urgent tasks of the contemporary narcology to date. The aim: The purpose of the paper was to reveal the significant pathogenetic factors for the psychosocial maladaptation formation in patients with alcohol dependence.

Multiple representations in visual working memory simultaneously guide attention: The type of memory-matching representation matters.

Whether multiple visual working memory (VWM) representations can simultaneously become active templates to guide attention is controversial. The single-item-template hypothesis argues that only one VWM representation can be active at a time, whereas the multiple-item-template hypothesis argues that multiple VWM templates can simultaneously guide attention. The present study examined the two hypotheses in three (out of four) experiments, using three different types of memory objects: Experiment 1: shapes; Ex...

Assessors' and trainees' perceptions of workplace-based assessments in histopathology.

Workplace-based assessments (WBAs) are an integral part of specialist medical and dental training in the UK. Histopathology represents a very different training environment to the surgical specialities so it is important to know that the current WBAs are fit for purpose. A literature search revealed very little evidence regarding the perception of WBAs in histopathology. The aim of this study was therefore to assess the current perception of WBAs in histopathology by assessors and trainees.

Efficacy and Safety of Indwelling Pleural Catheters in Management of Hepatic Hydrothorax: A Systematic Review of Literature.

Hepatic hydrothorax (HH) is an infrequent but debilitating and therapeutically challenging complication of advanced liver cirrhosis. As evidence suggests against chest tube placement in HH, many clinicians are reluctant to place indwelling pleural catheters (IPCs) for non-malignant effusions like HH. We aim to study the efficacy and safety of IPCs as an alternative treatment option in our systematic review. A literature search was conducted using the electronic database engines MEDLINE, PubMed, EMBASE, Ovi...

Differential expression of vitamin D associated genes in the aorta of coronary artery disease patients with and without rheumatoid arthritis.

Vitamin D has an important role in the immune system, and has been linked to rheumatoid arthritis (RA) and coronary artery disease (CAD). The exact mechanisms by which vitamin D is involved in these processes are still unclear. Therefore, we wanted to search for differences in expression of genes involved in the vitamin D receptor (VDR) activation pathway and genes that are known to alter upon vitamin D stimulation, in the aortic adventitia of CAD patients with and without RA.

Impact of the economic crisis on pain research: a bibliometric analysis of pain research publications from Ireland, Greece, and Portugal between 1997 and 2017.

Background and aims The recent economic crisis started in the USA in 2008 but quickly had worldwide impact. Ireland, Greece, and Portugal were in economic distress in 2009 and received rescue monetary packages from the European Union (EU) and the International Monetary Fund (IMF) in the following years. Meanwhile, the economic recovery has begun for those countries, but at different paces. The aim of the present study was to evaluate if the economic crisis influenced pain research outcomes, by performing a ...

Diurnal Variations of Depression-Related Health Information Seeking: Case Study in Finland Using Google Trends Data.

Some of the temporal variations and clock-like rhythms that govern several different health-related behaviors can be traced in near real-time with the help of search engine data. This is especially useful when studying phenomena where little or no traditional data exist. One specific area where traditional data are incomplete is the study of diurnal mood variations, or daily changes in individuals' overall mood state in relation to depression-like symptoms.

Coloseminal vesicle fistula after low anterior resection: Report of a case and review of the literature.

A rectoseminal vesicle fistula after a low anterior resection for rectal cancer is a rare complication despite their anatomic proximity. From a Medline search from 1966 to date, a total of twenty-one previous cases of coloseminal vesicle fistula have been reported. From these cases, eleven were a complication of laparoscopic low anterior resection for rectal cancer.

Extracting similar terms from multiple EMR-based semantic embeddings to support chart reviews.

Word embeddings project semantically similar terms into nearby points in a vector space. When trained on clinical text, these embeddings can be leveraged to improve keyword search and text highlighting. In this paper, we present methods to refine the selection process of similar terms from multiple EMR-based word embeddings, and evaluate their performance quantitatively and qualitatively across multiple chart review tasks.

Constraints on Exotic Spin-Dependent Interactions Between Matter and Antimatter from Antiprotonic Helium Spectroscopy.

Heretofore undiscovered spin-0 or spin-1 bosons can mediate exotic spin-dependent interactions between standard model particles. Here, we carry out the first search for semileptonic spin-dependent interactions between matter and antimatter. We compare theoretical calculations and spectroscopic measurements of the hyperfine structure of antiprotonic helium to constrain exotic spin- and velocity-dependent interactions between electrons and antiprotons.
