#1
Kinam Kwon, Dongchan Kim, HyunWook Park
PURPOSE: To reconstruct MR images from subsampled data, we propose a fast reconstruction method using the multilayer perceptron (MLP) algorithm. METHODS AND MATERIALS: We applied MLP to reduce aliasing artifacts generated by subsampling in k-space. The MLP is learned from training data to map aliased input images into desired alias-free images. The input of the MLP is all voxels in the aliased lines of multi-channel real and imaginary images from the subsampled k-space data, and the desired output is all voxels in the corresponding alias-free line of the root-sum-of-squares of multi-channel images from fully-sampled k-space data...

BACKGROUND: Breast reconstruction after mastectomy in the treatment of locally advanced breast cancer is often done in stages and before radiotherapy. We have previously published an algorithm for immediate free autologous reconstruction after neoadjuvant chemotherapy and preoperative radiotherapy. This protocol was designed to provide a shorter and simpler reconstructive path whilst improving cosmesis and maintaining oncological efficiency. METHODS: A total of 29 patients were included and underwent surgery for 30 cancers by the first author between 2010 and September 2015...

Ido Greenberg, Yoel Shkolnisky
We consider the problem of estimating an unbiased and reference-free ab-inito model for non-symmetric molecules from images generated by single-particle cryo-electron microscopy. The proposed algorithm finds the globally optimal assignment of orientations that simultaneously respects all common lines between all images. The contribution of each common line to the estimated orientations is weighted according to a statistical model for common lines' detection errors. The key property of the proposed algorithm is that it finds the global optimum for the orientations given the common lines...

Peri/post-operative antibiotic prophylaxis (POABP) has become standard practice for preventing surgical site infections (SSI) in head and neck cancer patients undergoing microvascular reconstruction, but few data exist on optimal POABP regimens. Current surgical prophylaxis guideline recommendations fail to account for the complexity of microvascular reconstruction relative to other head and neck procedures, specifically regarding wound classification and antibiotic duration. Selection of POABP spectrum is also controversial, and must balance the choice between too narrow, risking subsequent infection, or too broad, and possible unwanted effects (e...

Patient-reported quality of life (QoL) outcomes have the potential to assist clinicians in providing individually tailored treatment decisions. QoL assessments were collected prospectively for 168 consecutive patients treated for oral cancer between 1 January 2010 and 31 December 2014 using the University of Washington Quality of Life Questionnaire. Patients were followed up for 18 months post-treatment. Sub-group analyses were performed using paired t-tests and analysis of variance (ANOVA) to compare the effects of adjunctive chemoradiotherapy, type of bone resection, and methods of soft and hard tissue flap reconstruction...

REVIEW
E Bradley Strong, Celeste Gary
Zygomaticomaxillary fractures account for approximately 25% of all facial fractures. They can be grouped into high-velocity and low-velocity injuries. A complete head and neck examination is critical for accurate clinical diagnosis. A thin-cut axial CT scan with sagittal, coronal, and 3-D reconstruction is important for accurate diagnosis and treatment planning. A thorough understanding of bony tetrapod anatomy and fracture mechanics is critical to treatment planning. Treatment options include closed and open reduction with internal fixation...

Ionic liquid (IL)-acid pretreatment is known to not only enhance the enzymatic hydrolysis efficiency of lignocellulose but also to generate deposits on the surface of fiber by conventional water regeneration, which retard the increment. In this study, ethanol aqueous solution regeneration was developed as a new method to change the substrates characteristics for IL-acid pretreatment and their effects on the enzymatic hydrolysis were evaluated. Following the IL-acid reaction, the biomass slurry was subjected to ethanol aqueous solution at various concentration...

OBJECTIVE: Juvenile DermatoMyositis (JDM) is an inflammatory pediatric myopathy characterized by focal capillary loss in muscle, followed by a progressive recovery upon adequate immunomodulating treatments, although some patients remain refractory to treatments. While the underlying mechanism of capillary depletion remains uncertain, recent studies have identified an upregulation of type I Interferon (IFN-I) expression specific to JDM. Given that myogenic precursor cells (MPCs) exert pro-angiogenic activity during normal skeletal muscle regeneration, we hypothesized that they may also modulate vascular remodeling /angiogenesis during JDM...

Adalimumab and Infliximab are recombinant IgG1 monoclonal antibodies (mAbs) that bind and neutralize human tumor necrosis factor alpha (TNFα). TNFα forms a stable homotrimer with unique surface-exposed sites for Adalimumab, Infliximab and TNF receptor binding. Here, we report the structures of Adalimumab-TNFα and Infliximab-TNFα complexes modeled from negative stain EM and cryo-EM images. EM images reveal complex structures consisting of 1:1, 1:2, 2:2 and 3:2 complexes of Adalimumab-TNFα and Infliximab-TNFα...

Undetected in Europe since 2010, bluetongue virus serotype 8 (BTV-8) re-emerged in August 2015 in Central France. To gain insight into the re-emergence on the French territory, we estimated the seroprevalence in cattle before the detection of BTV-8 in 2015, in areas differentially affected by the current outbreak. A retrospective survey based on the analysis of stored sera was thus conducted in the winter preceding the re-emergence in seven French departments including the one where the virus was first detected...

Bottle gourd (Lagenaria siceraria) is an important vegetable crop as well as a rootstock for other cucurbit crops. In this study, we report a high-quality 313.4-Mb genome sequence of a bottle gourd inbred line, USVL1VR-Ls, with a scaffold N50 of 8.7 Mb and the longest of 19.0 Mb. About 98.3% of the assembled scaffolds are anchored to the 11 pseudomolecules. Our comparative genomic analysis identifies chromosome-level syntenic relationships between bottle gourd and other cucurbits, as well as lineage-specific gene family expansions in bottle gourd...
