Satish C. Bhatnagar (Math) gave an invited talk to the Gujarat Ganit Parishad and Geometry Club of Ahmedabad on an overseas trip to India in May. He gave the talk, "Navigating the Straits of Geometry," at the Vikram Sarabhai Science Community Center, which is near the main campus of Gujarat University.

Kai-Yu Ho (Physical Therapy) and David Lee (Life Sciences) received a Faculty Opportunity Award in the collaborative interdisciplinary research category for their study “Knee Pain, Tendon Degeneration, and Limb-Socket Dynamics in Trans-Tibial Amputees.” Their work seeks to understand how below-the-knee prosthetic sockets influence the transmission of loads and the deformation of tissues in the residual limb during walking, and then relate the parameters to patellar tendon morphology and clinical measures of knee joint function and pain.

Hui Zhang (Chemistry and Biochemistry) and a team of UNLV biochemistry researchers recently published a paper in the journal Nature Communications. The paper is entitled “Methylated DNMT1 and E2F are Targeted for Proteolysis by L3MBTL3 and CRL4DCAF5 Ubiquitin Ligase”. Lysine-specific methylation of histones is a major epigenetic modification that regulates chromatin structure and gene expression. Emerging evidence indicates that a large number of nonhistone proteins are also lysine methylated and a major function of this modification is to control the stability of the methylated proteins. The research team  discovered for the first time a novel mechanism by which the stability of methylated proteins is regulated to control the epigenetic inheritance of DNA methylation and gene expression during cell division.

Xiangxue Xiao and Yingke Xu (both Environmental and Occupational Health and Nevada Institute of Personalized Medicine), and Bowen Liu (Math and NIPM) recently published findings in Osteoporosis International, a high-impact peer-reviewed medical journal published by Springer that is an official journal of the International Osteoporosis Foundation and the National Osteoporosis Foundation. The graduate students’ findings resulted from projects they worked on while enrolled in EAB 788 in spring 2017, a course taught by professor Qing Wu (Environmental and Occupational Health and NIPM) that focuses on logic and application of meta-analysis in public health. Xiao and Xu published “Thiazide Diuretic Usage and Risk of Fracture: A Meta-Analysis of Cohort Studies” on March 25. Liu published “Depression and Risk of Fracture and Bone Loss: An Updated Meta-Analysis of Prospective Cohort Studies” on March 12.

Nora Caberoy (Life Sciences) and Francisco Sy (Community Health Sciences) gave their research presentations at the 38th Philippine American Academy of Science and Engineering Annual Meeting and Symposium public health session at the University of Arizona earlier this month. Caberoy presented her research "Lessons from the Eye: Can We Redirect the Cellular Eating Process to Prevent Alzheimer's Disease?" Dr. Sy presented " An Assessment of Filipino American Health in the Greater Las Vegas Area: A Pilot Study".

Andrea Darby (Life Sciences) recently won first prize in the Science Slam competition at the 59th Annual Drosophila Research Conference in Philadelphia. The title of her spoken word piece was "Pet Project." She is an undergraduate student in her senior year.

Jun Yong Kang and Hai Huang (both Chemistry and Biochemistry), as well as computational study collaborators at the University of Colorado, Denver, published a research article, "Direct Aryloxylation/Alkyloxylation of Dialkyl Phosphonates for the Synthesis of Mixed Phosphonates," in Angewandte Chemie. This research demonstrates a new synthetic transformation of dialkylphosphonates to mixed phosphonates under mild reaction conditions. The mixed phosphonates are prevalent in pharmaceuticals and bioactive small molecules such as antibacterial, ligand prodrug, and enzyme inhibitors. This synthetic method avoids the use of toxic metals, hazardous chloride reagents, and moisture sensitive chloride intermediates for the synthesis of biologically important mixed phosphonate compounds.

Boo Shan Tseng and Sophia Araujo Hernandez (both Life Sciences), as well as collaborators at the University of Washington and the University of Calgary, published a research article, "A Biofilm Matrix-Associated Protease Inhibitor Protects Pseudomonas Aeruginosa from Proteolytic Attack", in the high-impact journal mBio. The work shows that when bacteria grow in communities called biofilms, the material holding the bacteria together retains a specific extracellular protein. This protein protects the biofilm bacteria from a bactericidal enzyme that is commonly produced by the immune system during infection, representing yet another way biofilm bacteria, which are a common cause of chronic and hospital-acquired infections, can increase their tolerance against the immune response. Hernandez is one of Tseng's undergraduate students.

Jichun Li (Math) and collaborators published a paper "Mathematical Analysis and Finite Element Time Domain Simulation of Arbitrary Star-Shaped Electromagnetic Cloaks" in the top-tier journal SIAM Journal on Numerical Analysis in January. In March, he published a paper "Regularity Analysis of Metamaterial Maxwell’s Equations with Random Coefficients and Initial Conditions" in the highly ranked journal "Computer Methods in Applied Mechanics and Engineering".
