The world's coral reefs appear to be in a global decline, yet most previous research on coral reefs has taken place at depths shallower than 30 m. Mesophotic coral ecosystem (depths deeper than ~30 m) studies have revealed extensive, productive habitats and rich communities. Despite recent advances, mesophotic coral ecosystems remain understudied due to challenges with sampling at deeper depths. The few previous studies of mesophotic coral ecosystems have shown variation across locations in depth-specific species composition and assemblage shifts, potentially a response to differences in habitat or light availability/water clarity...

Tumor mutation load (TML) has been proposed as a biomarker of patient response to immunotherapy in several studies. TML is usually determined by tumor biopsy DNA (tDNA) whole exome sequencing (WES), therefore TML evaluation is limited by informative biopsy availability. Circulating cell free DNA (cfDNA) provided by liquid biopsy is a surrogate specimen to biopsy for molecular profiling. Nevertheless performing WES on DNA from plasma is technically challenging and the ability to determine tumor mutation load from liquid biopsies remains to be demonstrated...

Barbara Wilson, Lori Harwood
There is a lack of consensus in the literature on what constitutes successful arteriovenous fistula (AVF) cannulation outcomes from the patient perspective. The purpose of this study was to describe what successful cannulation means to patients on hemodialysis. A qualitative descriptive approach was used. A purposeful sample of 17 patients dialyzing with an AVF participated in one face-to-face interview. Using content analysis, four themes were identified that impact the patient experience in defining successful cannulation: 1) an emotional response - pain and anxiety, 2) a 'friendly' nurse-patient relationship, 3) nursing interventions/technical skills during cannulation, and 4) the impact of the environment...

Rangelands are Earth's dominant land cover and are important providers of ecosystem services. Reliance on rangelands is projected to grow, thus understanding the sensitivity of rangelands to future climates is essential. We used a new ecosystem model of moderate complexity that allows, for the first time, to quantify global changes expected in rangelands under future climates. The mean global annual net primary production (NPP) may decline by 10 g C m(-2) yr(-1) in 2050 under Representative Concentration Pathway (RCP) 8...

REVIEW
Klaske M Schukken, Floris Foijer
Chromosomal instability (CIN) and aneuploidy are similar concepts but not synonymous. CIN is the process that leads to chromosome copy number alterations, and aneuploidy is the result. While CIN and resulting aneuploidy often cause growth defects, they are also selected for in cancer cells. Although such contradicting fates may seem paradoxical at first, they can be better understood when CIN and aneuploidy are assessed separately, taking into account the in vitro or in vivo context, the rate of CIN, and severity of the aneuploid karyotype...

BACKGROUND: Extracellular volume (ECV) by T1 mapping requires the contrast agent distribution to be at equilibrium. This can be achieved either definitively with a primed contrast infusion (infusion ECV), or sufficiently with a delay postbolus (bolus-only ECV). For large ECV, the bolus-only approach measures higher than the infusion ECV, causing some uncertainty in diseases such as amyloidosis. PURPOSE: To characterize the relationship between the bolus-only and current gold-standard infusion ECV in patients with amyloidosis...

BACKGROUND: Pediatric retroperitoneal tumors in the renal bed are often large and heterogeneous, and their diagnosis based on conventional imaging alone is not possible. More advanced imaging methods, such as diffusion-weighted (DW) MRI and the use of intravoxel incoherent motion (IVIM), have the potential to provide additional biomarkers that could facilitate their noninvasive diagnosis. PURPOSE: To assess the use of an IVIM model for diagnosis of childhood malignant abdominal tumors and discrimination of benign from malignant lesions...

BACKGROUND: Critical incidents in difficult airway management are still a main contributory factor for perioperative morbidity and mortality. Many national associations have developed algorithms for management of these time critical events. For implementation of these algorithms the provision of technical requirements and procedure-related training are essential. Severe airway incidents are rare events and clinical experience of the individual operators is limited; therefore, simulation is an adequate instrument for training and evaluating difficult airway algorithms...

Currently, endovascular coiling is a popular treatment for basilar tip aneurysms, which usually involve a wide neck. Serious complications can occur when the posterior cerebral artery (PCA) originating from a wide neck is not properly preserved. Accordingly, various adjunctive procedures using stents or a balloon have been introduced. Herein we report two cases of basilar tip aneurysms in which retrograde horizontal (from one PCA to the other PCA) stent-assisted coiling was successful, and we provide a summary of the important technical points...
