BACKGROUND: Lymphedema is an iatrogenic complication after breast cancer treatment in which lymph fluid in the affected limb progresses to fat deposition and fibrosis that are amenable to liposuction treatment. Magnetic resonance imaging (MRI) for lymphedema can differentiate fat tissue from fluid, but estimating relative volumes remains problematic. METHODS AND RESULTS: Patients underwent routine bilateral arm MRI both before and after liposuction for advanced lymphedema...

Radiologic images are vast three-dimensional data sets in which each voxel of the underlying volume represents distinct physical measurements of a tissue-dependent characteristic. Advances in technology allow radiologists to image pathologies with unforeseen detail, thereby further increasing the amount of information to be processed. Even though the imaging modalities have advanced greatly, our interpretation of the images has remained essentially unchanged for decades. We have arrived in the era of precision medicine where even slight differences in disease manifestation are seen as potential target points for new intervention strategies...

Entanglement is one of the most fascinating properties of quantum mechanical systems; when two particles are entangled the measurement of the properties of one of the two allows to instantaneously know the properties of the other, whatever the distance separating them. In parallel with fundamental research on the foundations of quantum mechanics performed on complex experimental set-ups, we assist today to a bourgeoning of quantum information technologies bound to exploit entanglement for a large variety of applications such as secure communications, metrology and computation...

Assisted reproductive technology (ART) can benefit from the features of microfluidic technologies, such as the automation of time-consuming labor-intensive procedures, the possibility to mimic in vivo environments, and the miniaturization of the required equipment. To date, most of the proposed approaches are based on polydimethylsiloxane (PDMS) as platform substrate material due to its widespread use in academia, despite certain disadvantages, such as the elevated cost of mass production. Herein, we present a rapid fabrication process for a cyclic olefin copolymer (COC) monolithic microfluidic device combining hot embossing-using a low-temperature cofired ceramic (LTCC) master-and micromilling...

The domain of biobanking has gone through many stages and as a result there are a wide range of commercial and open source software solutions available. The utilization of these software tools requires different levels of domain and technical skills for installation, configuration and ultimate us of these biobank software tools. To compound this complexity the biobanking community are required to work together in order to share knowledge and jointly build solutions to underpin the research infrastructure. We have evaluated the available tools, described them in a catalogue (BiobankApps) and made a selection of tools available to biobanks in a reference toolbox (BIBBOX) that are use-case driven...

Computer-based scaffolding assists students as they generate solutions to complex problems, goals, or tasks, helping increase and integrate their higher order skills in the process. However, despite decades of research on scaffolding in STEM (science, technology, engineering, and mathematics) education, no existing comprehensive meta-analysis has synthesized the results of these studies. This review addresses that need by synthesizing the results of 144 experimental studies (333 outcomes) on the effects of computer-based scaffolding designed to assist the full range of STEM learners (primary through adult education) as they navigated ill-structured, problem-centered curricula...

PURPOSE: The aim of this work is to develop a scalable continuous system suitable for the formulation of polymeric nanoparticles using membrane-assisted nanoprecipitation. One of the hurdles to overcome in the use of nanostructured materials as drug delivery vectors is their availability at industrial scale. Innovation in process technology is required to translate laboratory production into mass production while preserving their desired nanoscale characteristics. METHODS: Membrane-assisted nanoprecipitation has been used for the production of Poly[(D,L lactide-co-glycolide)-co-poly ethylene glycol] diblock) (PLGA-PEG) nanoparticles using a pulsed back-and-forward flow arrangement...

This study presents evidence on the role of emotions in the monetary evaluation of health technologies, namely, drug-eluting stents (DES) in our case. It is shown that subjects who are very afraid of having to undergo an angioplasty are: (a) less sensitive to the size of the risk reduction provided by DES and (b) willing to pay more. The lack of scope sensitivity questions the normative validity of the responses of highly emotional subjects. We provide evidence of this effect using what we call the cognitive-emotional random utility model and the responses of a face-to-face, computer-assisted personal interview survey conducted in a representative sample of the Spanish general population (n = 1663)...

REVIEW
Michael S Kinch, Pamela Woodard
The development of imaging agents was initially driven following the discovery of X-ray technologies, but quickly evolved and expanded to include radiolabeling of cells and tissues to assist disease diagnosis and progression. The first imaging agents preceded the Great War but the field did not gain momentum until the 1950s. The approval rate for imaging NMEs continued at a high level for the remainder of the 20th century, but substantially decreased thereafter. This decline in approval rates corresponds with industry consolidation...

Terence T Lao
Thalassemia is the commonest monogenic disease and manifests as severe anemia. It is increasingly encountered outside the Mediterranean region, Africa, Middle East, and Southeast Asia because of immigration. Pregnancy, previously uncommon in patients with homozygous β-thalassemia, is encountered increasingly because of improved management and assisted reproduction technology; however, preconceptional problems that include anemia, iron overload, cardiac dysfunction, thromboembolism, alloimmunization, infections, and endocrine and bone disorders, could influence maternal and obstetric outcome...
