INTRODUCTION: Many teachers adopt instructional methods based on assumptions of best practices without attention to or knowledge of supporting education theory. Familiarity with a variety of theories informs education that is efficient, strategic, and evidence-based. As part of the Academic Life in Emergency Medicine Faculty Incubator Program, a list of key education theories for junior faculty was developed. METHODS: A list of key papers on theories relevant to medical education was generated using an expert panel, a virtual community of practice synthetic discussion, and a social media call for resources...

Virtual journal clubs (VJCs) provide a standardized, easily accessible forum for evidence-based discussion. The new virtual reality setting in which journal clubs and other online education events now take place offers great advantages and new opportunities for radiologists in academic medicine and private practice. VJCs continue to evolve, largely due to many emerging technologies and platforms. VJCs will continue to play an increasingly important role in medical education, interdisciplinary interaction, and multi-institutional collaboration...

PURPOSE: To describe a model-based reconstruction strategy for single-shot echo planar imaging (EPI) that intrinsically accounts for k-space nonuniformity, Nyquist ghosting, and geometric distortions during rather than before or after image reconstruction. METHODS: Ramp sampling and inhomogeneous B0 field-induced distortion cause the EPI samples to lie on a non-Cartesian grid, thus requiring the nonuniform fast Fourier transform. Additionally, a 2D Nyquist ghost phase correction without the need for extra navigator acquisition is included in the proposed reconstruction...

PURPOSE: To demonstrate the feasibility of turning transcranial magnetic stimulation (TMS) coil for MRI signal reception. METHODS: A critically coupled network was formed by using a resonated turn of TMS coil as the secondary and a regular radiofrequency (RF) coil as the primary. A third coil was positioned between the two coils for detuning during RF transmission. Bench measurement, numerical simulation, and MRI experiment were performed for validation. RESULTS: The signal-to-noise ratio of the proposed 2-in-1 coil is 35% higher in its field of view, compared with a MRI-only reference coil of the same size, made by the same material, and backed up by an untuned TMS coil, but lower than a RF surface coil of the same size without any TMS coil nearby...

It is known that some antidepressants and antipsychotics directly inhibit NMDA-type ionotropic glutamate receptors. In this study we systematically studied action of seven drugs (Fluoxetine, Citalopram, Desipramine, Amitriptyline, Atomoxetine, Chlorpromazine, and Clozapine) on NMDA receptors and Ca(2+)-permeable and -impermeable AMPA receptors in rat brain neurons by whole-cell patch-clamp technique. Except for weak effect of fluoxetine, all drugs were virtually inactive against Ca(2+)-impermeable AMPA receptors...

BACKGROUND: MNK1 and MNK2 are MAP kinase-interacting serine/threonine kinases, which are activated by RAS and MAPK signaling pathways and are involved in regulation of protein translation. Both kinases phosphorylate translation initiation factor eIF4E on a conserved serine 209. Overactivated eIF4E can act as an oncogene and contribute to the transformation both in vitro and in vivo and is highly expressed in diverse types of cancer. Interestingly, knockout mice that lack both Mnk1 and Mnk2 do not have any apparent phenotype...

This article demonstrates the relevance of animals to medical sociology by arguing that pet owners' accounts of veterinary decision-making can highlight key sociological themes which are important to both human and animal health. Based on semi-structured interviews, the article argues that interspecies 'kinship' allows for the extension of sociological claims regarding altruism, self-interest and mutuality from human blood donation to companion animal blood 'donation'. Furthermore, this study extends sociological understanding of the human-animal bond by showing how the dog's status as kin meant they were expected to donate blood, and that the act of donation itself represents an important opportunity for family 'display'...

The increasing level of antibiotic resistance in Gram-negative bacteria, together with the lack of new potential drug scaffolds in the pipeline, make the problem of infectious diseases a global challenge for modern medicine. The main reason that Gram-negative bacteria are particularly challenging is the presence of an outer cell-protecting membrane, which is not present in Gram-positive species. Such an asymmetric bilayer is a highly effective barrier for polar molecules. Several protein systems are expressed in the outer membrane to control the internal concentration of both nutrients and noxious species, in particular: (i) water-filled channels that modulate the permeation of polar molecules and ions according to concentration gradients, and (ii) efflux pumps to actively expel toxic compounds...

The ability to isolate specific, viable cell populations from mixed ensembles with minimal manipulation and within intra-operative time would provide significant advantages for autologous, cell-based therapies in regenerative medicine. Current cell-enrichment technologies are either slow, lack specificity and/or require labelling. Thus a rapid, label-free separation technology that does not affect cell functionality, viability or phenotype is highly desirable. Here, we demonstrate separation of viable from non-viable human stromal cells using remote dielectrophoresis, in which an electric field is coupled into a microfluidic channel using shear-horizontal surface acoustic waves, producing an array of virtual electrodes within the channel...

One of the most studied anti-cancer compounds of the last several decades is the microtubule targeting agent and cis-stilbene, combretastatin A4 (CA4). Despite promising results at the pre-clinical level, future clinical use of CA4 as a monotherapy is in question due metabolic vulnerability and conformational instability. Thus, medicinal chemists have focused on synthesizing derivatives with improved pharmokinetic profile. One common strategy has been the incorporation of the ethylene linker into a ring system, thus preventing the isomerization of CA4 into the virtually inactive trans-isomer...

We report a case of breast-conserving surgeryusing real-time virtual sonography(RVS)in a breast cancer patient who received neoadjuvant chemotherapy(NAC). The patient was a 63-year-old woman. Ultrasound(US)showed a lobulated 45 ×40×40mm diameter mass in the C area of the right breast. Histological examination found invasive ductal carcinoma that was negative for estrogen and progesterone receptors and for human epidermal growth factor receptor type 2/neu protein expression, and the Ki-67 index was 50%. The patient was diagnosed with breast cancer clinical stage II A(T2N0M0)...

BACKGROUND: Simulation in medicine is an indispensable tool to improve doctors' responses to different situations, enhancing their performance. However, simulation in ophthalmology is a very recent trend, mainly because of the high complexity of developing newer teaching tools, with the need for highly realistic models, mostly in surgical ophthalmic simulation. DISCUSSION: The whole development of simulation in ophthalmology, from the very first attempts that used basic models, to the newer virtual reality models, allows for a comprehensive, faster, and more efficient development of skills necessary in basic and advance procedures in ophthalmology, creating a better learning environment, improving costs, and developing a very promising panorama, in which simulation can be incorporated in teaching programs all around the globe...

Artificial Intelligence (AI) is a general term that implies the use of a computer to model intelligent behavior with minimal human intervention. AI is generally accepted as having started with the invention of robots. The term derives from the Czech word robota, meaning biosynthetic machines used as forced labor. In this field, Leonardo Da Vinci's lasting heritage is today's burgeoning use of robotic-assisted surgery, named after him, for complex urologic and gynecologic procedures. Da Vinci's sketchbooks of robots helped set the stage for this innovation...

Melanogenesis is a process to synthesize melanin, which is a primary responsible for the pigmentation of human skin, eye and hair. Although numerous enzymatic catalyzed and chemical reactions are involved in melanogenesis process, the enzymes such as tyrosinase and tyrosinase-related protein-1 (TRP-1) and TRP-2 played a major role in melanin synthesis. Specifically, tyrosinase is a key enzyme, which catalyzes a rate-limiting step of the melanin synthesis, and the downregulation of tyrosinase is the most prominent approach for the development of melanogenesis inhibitors...
