OBJECTIVE: To compare two fat suppression techniques used for 3D T1-weighted sequence in breast MRI (magnetic resonance imaging), namely Dixon versus spectral fat saturation (fat sat). MATERIALS AND METHODS: All breast MRI examinations performed in a Philips 3 T unit between March 2013 and October 2015 including either a Dixon or a fat sat sequence were retrospectively analyzed. The examinations were subjectively evaluated by two independent experienced readers in a scale of 5 for overall quality of fat suppression, homogeneity of fat suppression, definition of anatomic structures and focal lesions, diagnostic confidence for axillary and internal mammary regions and the presence of artifacts, 1 corresponding to excellent and 5 to non-diagnostic quality...

We conducted a prospective interventional study to evaluate the role of endoscopic endonasal dacryocystorhinostomy in children. Our study population was made up of 20 patients-18 boys and 2 girls, aged 2 to 12 years (mean: 5.3)-who presented with signs and symptoms suggestive of nasolacrimal duct blockage that was refractory to conventional medical treatment. In all cases, blockage was confirmed by nasolacrimal duct syringing that demonstrated regurgitation from the opposite punctum. The primary outcome measures for success were resolution of symptoms and duct patency on lacrimal irrigation...

Nitrogen is one of the most important elements for plants and is closely related to photosynthesis. High temperature stress significantly inhibits photosynthesis under both steady-state and flecked irradiance. However, it is not known whether nitrogen can affect the decrease in photosynthesis caused by high temperature, especially under flecked irradiance. In the present study, a pot experiment was conducted under two nitrogen (N) supplies with rice plants, and the steady-state and dynamic photosynthesis rates were measured under 28 and 40°C...

White adipose tissue (WAT) plays a central role in whole-body energy homeostasis through storage and release of fatty acids. A deeper understanding of the complex and highly integrated pathways regulating WAT fatty acid metabolism, and how they are altered with obesity, is necessary for diagnostic and therapeutic innovations in nutritional disorders. In this multi-omics study, we investigated the influence of obesity on fatty acid metabolism in human subcutaneous adipose tissue (SAT) using an approach that integrated transcriptomic, peptidomic, and fatty acid analyses...

Enteroaggregative Escherichia coli (EAEC) is frequently found in diarrheal stools worldwide. It has been associated with persistent diarrhea, weight loss, and failure to thrive in children living in developing countries. A number of important EAEC virulence genes are identified; however, their roles in acute and persistent diarrhea have not been previously investigated. The aim of this study was to identify specific EAEC virulence genes associated with duration and type of diarrhea in Danish children. We aimed to improve the current diagnostics of EAEC and enable targeting of strains with an expected severe disease course...

Studies generally show children who have entered out-of-home care have worse educational outcomes than the general population, although recent research suggests maltreatment and other adversities are major contributing factors. Children's out-of-home care experiences vary and may affect their outcomes. This study examined the influence of placement stability, reunification, type of care, time in care and age at entry to care on children's educational outcomes. We conducted a population-based record-linkage study of children born in Western Australia between 1990 and 2010 who sat State or national Year 3 reading achievement tests (N=235,045 children, including 2160 children with a history of out-of-home care)...

Much has been written about the learning benefits of peer teaching for medical trainees. What remains less certain is how practically to implement "Student-as-teacher" (SaT) programs combining teacher-skills training with hands-on teaching experiences for medical students to prepare them for their roles as teachers in residency and beyond. In this article, we address this gap by outlining twelve tips for the implementation of SaT programs based on review of the literature and our experience implementing SaT curricula at our institution...

BACKGROUND: Hepatopulmonary syndrome is a severe complication of liver disease, with greatly increased mortality. The syndrome is characterized by increased blood-flow, intrapulmonary vasodilatation and angiogenesis, leading to effects including the formation of shunts. This leads to a decrease in arterial oxygen pressure. Liver transplantation is the only effective treatment. CASE DESCRIPTION: A 74-year-old woman with cirrhosis of the liver attended the pulmonary outpatients' clinic with progressive dyspnoea, which worsened if she sat upright from a lying position (platypnoea)...

Saponins are secondary metabolites that are widely distributed in plants. There are two major saponin precursors in soybean: soyasapogenol A, contributing to the undesirable taste, and soyasapogenol B, some of which have health benefits. It is important to control the ratio and content of the two major saponin groups to enhance the appeal of soybean as a health food. The structural diversity of saponin in the sugar chain composition makes it hard to quantify the saponin content. We measured the saponin content in soybean by removing the sugar chain from the saponin using acidic hydrolysis and detected novel quantitative trait loci (QTLs) for saponin content...

In April 2016, southeast Asia experienced surface air temperatures (SATs) that surpassed national records, exacerbated energy consumption, disrupted agriculture and caused severe human discomfort. Here we show using observations and an ensemble of global warming simulations the combined impact of the El Niño/Southern Oscillation (ENSO) phenomenon and long-term warming on regional SAT extremes. We find a robust relationship between ENSO and southeast Asian SATs wherein virtually all April extremes occur during El Niño years...
