With the recent clinical implementation of real-time MRI guided x-ray beam therapy (MRXT), attention is therapy (MRPT). MRI guidance for proton beam therapy is expected to offer a compelling improvement to the turning to the concept of combining real-time MRI guidance with proton beam therapy; MRI guided proton beam current treatment workflow which is warranted arguably more than for x-ray beam therapy. This argument is born out of the fact that proton therapy toxicity outcomes are similar to that of the most advanced IMRT treatments, despite being a fundamentally superior particle for cancer treatment...

Matt Shirley
Dupilumab (Dupixent(®)) is a fully human monoclonal antibody directed against the interleukin (IL)-4 receptor α (IL-4Rα) subunit. Dupilumab inhibits the signalling of the type 2 cytokines IL-4 and IL-13 and was co-developed by Regeneron Pharmaceuticals and Sanofi as a potential therapeutic agent for the treatment of atopic or allergic diseases. In March 2017 dupilumab received its first global approval, in the USA, for use in the treatment of adult patients with moderate-to-severe atopic dermatitis whose disease is not adequately controlled with topical prescription therapies or when those therapies are not advisable...

BACKGROUND: Understanding the genotype-phenotype map is fundamental to our understanding of genomes. Genes do not function independently, but rather as part of networks or pathways. In the case of metabolic pathways, flux through the pathway is an important next layer of biological organization up from the individual gene or protein. Flux control in metabolic pathways, reflecting the importance of mutation to individual enzyme genes, may be evolutionarily variable due to the role of mutation-selection-drift balance...

Bacteriophages are ubiquitous and affect most facets of life, from evolution of bacteria, through ecology and global biochemical cycling to human health. The interactions between phages and bacteria often lead to biological novelty and an important milestone in this process is the ability of phages to regulate their host's behavior. In this review article, we will focus on newly reported cases that demonstrate how temperate phages regulate bacterial gene expression and behavior in a variety of bacterial species, pathogenic and environmental...

Germinal vesicle breakdown (GVBD) is the first milestone that an oocyte needs to achieve towards completing the maturation and gaining potential to fertilise. Significantly lower in vitro embryo production rate in buffaloes can be attributed to heterogeneity of GVBD occurrence among oocytes obtained from abattoir derived ovaries. Evidence from our earlier work had suggested that different qualities of buffalo oocytes differ significantly in their timing of GVBD. Besides, these oocytes also differ in terms of volume of Akt phosphorylation, which initiates the process of GVBD...

The enhancement of thermoelectric figure of merit ZT requires to either increase the power factor or reduce the phonon conductance, or even both. In graphene, the high phonon thermal conductivity is the main factor limiting the thermoelectric conversion. The common strategy to enhance ZT is therefore to introduce phonon scatterers to suppress the phonon conductance while retaining high electrical conductance and Seebeck coefficient. Although thermoelectric performance is eventually enhanced, all studies based on this strategy show a significant reduction of the electrical conductance...

The vitamin B12 status of infants depends on maternal B12 status during pregnancy, and during lactation if breastfed. We present a 9-month-old girl who was admitted to the metabolic unit for assessment of developmental delay. She was exclusively breastfed and the introduction of solids at 5 months was unsuccessful. Investigations revealed pancytopenia, undetectable B12 and highly elevated methylmalonic acid and homocysteine. Methylmalonic acid and homocysteine normalised following B12 injections. Marked catch-up of developmental milestones was noted after treatment with B12...

Canada's approach to shared decision making (SDM) remains as disparate as its healthcare system; a conglomerate of 14 public plans - ten provincial, three territorial and one federal. The healthcare research funding environment has been largely positive for SDM because there was funding for knowledge translation research which also encompassed SDM. The funding climate currently places new emphasis on patient involvement in research and on patient empowerment in healthcare. SDM fields have expanded from primary care to elder care, paediatrics, emergency and critical care medicine, cardiology, nutrition, occupational therapy and workplace rehabilitation...

The "Innsbruck Goggle Experiments" on long-term wearing of reversing mirrors, prismatic and half prismatic goggles, and colored half goggles represent a milestone in research on adaptation (adapting to the introduced "disturbance") and after-effects (after removal of the "disturbance"). By means of these goggles it is, for example, possible to invert or distort the visual field (such as flipping top and bottom or left and right), as well as to observe how individuals learn to change the image back to vertical or recognize left and right...

Neurodevelopmental reflex testing is commonly used in clinical practice to assess the maturation of the nervous system. Neurodevelopmental reflexes are also referred to as primitive reflexes. They are sensitive and consistent with later outcomes. Abnormal reflexes are described as an absence, persistence, reappearance, or latency of reflexes, which are predictive indices of infants that are at high risk for neurodevelopmental disorders. Animal models of neurodevelopmental disabilities, such as cerebral palsy, often display aberrant developmental reflexes, as would be observed in human infants...
