#1
X Liao, J Deng, J Y Xun, J X Yan
In the past decade, based on the "common disease-common variant" hypothesis, genomewide association studies (GWAS) have been extensively used to dissect the genetic components of complex diseases and quantitative traits. However, the identified disease-associated common variants by GWASs can only explain small part of the corresponding disease heritability. "Common disease-rare variant" hypothesis has been proposed to explore the missed heritability. With the development of the next generation sequencing technology, various association studies of less common variants are ongoing...

INTRODUCTION: Fluorescence-guided surgery has emerged as a powerful tool to detect, localize and resect tumors in the operative setting. Our laboratory has pioneered a novel way to administer an FDA-approved near-infrared (NIR) contrast agent to help surgeons with this task. This technique, coined Second Window ICG, exploits the natural permeability of tumor vasculature and its poor clearance to deliver high doses of indocyanine green (ICG) to tumors. This technique differs substantially from established ICG video angiography techniques that visualize ICG within minutes of injection...

Enoxaparin is a low-molecular weight heparin used to treat thrombotic disorders. Following the fatal contamination of the heparin supply chain in 2007-2008, the U.S. Pharmacopeia (USP) and U.S. Food and Drug Administration (FDA) have worked extensively to modernize the unfractionated heparin and enoxaparin monographs. As a result, the determination of molecular weight (MW) has been added to the monograph as a measure to strengthen the quality testing and to increase the protection of the global supply of this life-saving drug...

Shortage of donors still is the major obstacle for kidney transplantation. Living-related donors are the major resource of kidney transplantation at present. To expand the donor pool, spousal-donor kidney transplantation as one of the types of living-unrelated donors has been used to alleviate the organ shortage. A total of 116 living-kidney transplantations were retrospectively analyzed. We classified these recipients into two groups: a spousal-donor group (n = 50) and a living-related donor group (n = 66), and analyzed the outcome of transplantation...

To clarify the organization of motor representations in posterior parietal cortex, we test how three motor variables (body side, body part, cognitive strategy) are coded in the human anterior intraparietal cortex. All tested movements were encoded, arguing against strict anatomical segregation of effectors. Single units coded for diverse conjunctions of variables, with different dimensions anatomically overlapping. Consistent with recent studies, neurons encoding body parts exhibited mixed selectivity. This mixed selectivity resulted in largely orthogonal coding of body parts, which "functionally segregate" the effector responses despite the high degree of anatomical overlap...

Urocanic acid (UCA) is known as a major chemoattractant for Strongyloides stercoralis infective third-stage larvae (L3). Since Brugia pahangi is a skin-penetrating parasitic nematode similar to S. stercoralis, UCA was expected to be a chemoattractant for B. pahangi L3. Thus, the chemoattractant activity of UCA for B. pahangi L3 was assessed. The chemotactic responses of B. pahangi L3 to UCA or acetic acid (CH3COOH) dissolved in amine solutions were assessed using an agar-plate assay. A test solution of 200 mm UCA dissolved in aqueous 270 mm tris(hydroxymethyl)aminomethane (Tris) significantly attracted B...
