Society expects that the wave of contemporary new discoveries in biological sciences will soon lead to novel treatments for human diseases, including many devastating brain disorders. Historically, medicinal chemists have contributed to drug discovery teams in ways that synergize with those from their partner sciences, and help transform new knowledge into the ultimate tangible asset: a new drug. The optimal balance of resources and the right strategy to minimize the risk of late clinical failure may differ for different therapeutic indications...

OBJECTIVE: To determine the informational consistency produced by the two most recent independent surveys and draw a conclusion whether the data would be sufficient for the National Center for Health Workforce Analysis and Bureau of Labor and Statistics consideration. METHODS: This paper compares workforce outcomes collected by the two most prominent acupuncture entities that have produced the most useful acupuncturist workforce data (California Acupuncture Board 2015 Occupational Analysis and the National Certification Commission of Acupuncture and Oriental Medicine® 2013 Job Analysis) at national and state levels...

Hahnsung Kim, Dong-Hyun Kim, Chul-Ho Sohn, Jaeseok Park
PURPOSE: To investigate the feasibility of chemical shift encoded, single-slab 3D GRASE for rapid fat-water separation within a single acquisition. METHODS: The proposed method incorporates signal-to-noise-ratio-optimal chemical shift encoding into single-slab 3D GRASE with variable flip angles. Chemical shift induced phase information was encoded in succession to different positions in k-space by inserting phase encoding blips between adjacent lobes of the oscillating readout gradients...

PURPOSE: The purpose of this work was to assess the impact of respiratory motion and to compare methods for suppression of respiratory motion artifacts in 4D Flow MRI. METHODS: A numerical 3D aorta phantom was designed based on an aorta velocity field obtained by computational fluid mechanics. Motion-distorted 4D Flow MRI measurements were simulated and several different motion-suppression techniques were evaluated: Gating with fixed acceptance window size, gating with different window sizes in inner and outer k-space, and k-space reordering...

Priti Mehta, Dhara Bhayani
To upkeep health of astronauts in a unique, isolated, and extreme environment of space is the primary goal for a successful space mission, hence, safe and efficacious medications are essential for the wellness of astronauts. Space medication has been challenged with problems related to efficacy. Along with altered physiology, one of the possible reasons could be instability of space medications in the presence of harsh spaceflight environmental conditions. Altered physical and chemical stability can result in reduced potency which can result in reduced efficacy...

William B Ventres
In this essay, I borrow the idea of universal precautions from infection control and suggest that family physicians use a set of considerations, based on the mnemonic UNIVERSAL, to nurture cultural humility, enter a metaphoric "space-in-between" in cross-cultural encounters, and foster global fluency. These UNIVERSAL considerations I base on my experiences in global family medicine, attending to economically poor and socially marginalized patients in both international and domestic settings. They are informed by readings in transcultural psychiatry, medical anthropology, development studies, and primary care...

Despite the high HIV burden faced by sex workers, data on access and retention in antiretroviral therapy (ART) are limited. Using an innovative spatial epidemiological approach, we explored how the social geography of sex work criminalization and violence impacts HIV treatment interruptions among sex workers living with HIV in Vancouver over a 3.5-year period. Drawing upon data from a community-based cohort (AESHA, 2010-2013) and linked external administrative data on ART dispensation, GIS mapping and multivariable logistic regression with generalized estimating equations to prospectively examine the effects of spatial criminalization and violence near women's places of residence on 2-day ART interruptions...

Manoj Kumar, Tanpreet Kaur, Anuj Sharma
In the present report, the role of computationally estimated efficiency indices and pose clustering has been demonstrated in effective decision making, resource management and chemical prioritization. As an example, 720 annulated furanones from six different scaffold classes were computationally docked against Pf-DHFR active site using AutoDock 4.2. Many trends were established by navigating efficiency indices (BEI and SEI) in 2D planes. These trends were then explained by comparing interaction profiles of docked poses with that of known actives/inhibitors...

Experimental research in medical physics has expanded the limits of our knowledge and provided novel imaging and therapy technologies for patients around the world. However, experimental efforts are challenging due to constraints in funding, space, time and other forms of institutional support. In this joint ESTRO-AAPM symposium, four exciting experimental projects from four different countries are highlighted. Each project is focused on a different aspect of radiation therapy. From the USA, we will hear about a new linear accelerator concept for more compact and efficient therapy devices...

PURPOSE: Multiparametric radiological imaging is used for diagnosis in patients. Potentially extracting useful features specific to a patient's pathology would be crucial step towards personalized medicine and assessing treatment options. In order to automatically extract features directly from multiparametric radiological imaging datasets, we developed an advanced unsupervised machine learning algorithm called the multidimensional imaging radiomics-geodesics(MIRaGe). METHODS: Seventy-six breast tumor patients underwent 3T MRI breast imaging were used for this study...

PURPOSE: Scatter correction in cone-beam computed tomography (CBCT) has obvious effect on the removal of image noise, the cup artifact and the increase of image contrast. Several methods using a beam blocker for the estimation and subtraction of scatter have been proposed. However, the inconvenience of mechanics and propensity to residual artifacts limited the further evolution of basic and clinical research. Here, we propose a rotating collimator-based approach, in conjunction with reconstruction based on a discrete Radon transform and Tchebichef moments algorithm, to correct scatter-induced artifacts...

INTRODUCTION: One-stage implant-based breast reconstruction has been recently improved by the introduction of biological [acellular dermal matrix (ADM)] and synthetic meshes. Advantages of ADMs in implant-based breast reconstruction derive from the expansion of the space available for the direct positioning of an implant, but their use could be associated with several complications. Although the majority of complications can be easily managed, mistakes in dealing with the first clinical signs of a potential adverse event can lead to implant loss...

: Although osmidrosis has been widely discussed in respect to its treatment modalities, there has been no definite consideration of postoperative management after the treatment of osmidrosis. We have tested the 40-125 mmHg range of negative pressure. We present negative pressure wound therapy (NPWT) of 70 mmHg for postoperative management in osmidrosis because NPWT has a role in removing fluid, such as blood or seroma, and diminishing the dead space between the skin and subcutaneous tissue...

Tremendous differences between human sexes are universally observed. Therefore, identifying and analyzing the sex-biased genes are becoming basically important for uncovering the mystery of sex differences and personalized medicine. Here, we presented a computational method to identify sex-biased genes from public gene expression databases. We obtained 1407 female-biased genes (FGs) and 1096 male-biased genes (MGs) across 14 different tissues. Bioinformatics analysis revealed that compared with MGs, FGs have higher evolutionary rate, higher single-nucleotide polymorphism density, less homologous gene numbers and smaller phyletic age...
