Background: Long-read sequencing is rapidly evolving and reshaping the suite of opportunities for genomic analysis. For the MinION in particular, as both the platform and chemistry develop, the user community requires reference data to set performance expectations and maximally exploit third-generation sequencing. We performed an analysis of MinION data derived from whole genome sequencing of K...

Goals and Education Materials The project began by considering ways in which technology could improve learning in introductory chemistry courses. Chemistry concepts are abstract and initially are difficult to attach to real-world experience. For this reason, high school and college chemistry courses have evolved a standard set of paper-and-pencil manipulations (dimensional analysis, balancing e...

Human AP endonuclease 1 (APE1, REF1) functions within the base excision repair pathway by catalyzing the hydrolysis of the phosphodiester bond 5 ' to a baseless sugar (apurinic or apyrimidinic site). The AP endonuclease activity of this enzyme and two active site mutants were characterized using equilibrium binding and pre-steady-state kinetic techniques. Wild-type APE1 is a remarkably potent e...

Fatemeh Karimi Tabar was born in Asadabad/Hamedan (Iran) in 1986. She completed her B.Sc. in chemistry in 2008 from Bu-Ali Sina University, Hamedan, Iran. She was graduated from M.Sc. degree in organic chemistry from Shiraz University 2010, Shiraz, Iran. She is currently Organic Chemistry Ph.D student under the supervision of prof. M.A. Zolfigol and prof. A. Khazaei in department of chemistry a...

Vegetation emits large quantities of biogenic volatile organic compounds (BVOC). At remote sites, these compounds are the dominant precursors to ozone and secondary organic aerosol (SOA) production, yet current field studies show that atmospheric models have difficulty in capturing the observed HOx cycle and concentrations of BVOC oxidation products. In this manuscript, we simulate BVOC chemist...

Medicinal chemistry is an interdisciplinary science at the intersection of organic chemistry, biochemistry (bioorganic chemistry), computational chemistry, pharmacology, pharmacognosy, molecular biology, and physical chemistry. This branch of chemistry is involved with the identifi cation, design, synthesis, and development of new drugs that are safe and suitable for therapeutic use in humans a...

The central role that phosphates play in biological systems, suggests they also played an important role in the emergence of life on Earth. In recent years, numerous important advances have been made towards understanding the influence that phosphates may have had on prebiotic chemistry, and here, we highlight two important aspects of prebiotic phosphate chemistry. Firstly, we discuss prebiotic...

The DNA duplex is an exquisite macromolecular array that stores genetic information to encode proteins and regulate pathways. Its unique structure also imparts chemical function that allows it also to mediate charge transport (CT). We have utilized diverse platforms to probe DNA CT, using spectroscopic, electrochemical, and even genetic methods. These studies have established powerful features ...

A new recoverable molybdenum nanocatalyst was prepared by immobilization  of a Schiff base ligand on the surface of silica coated magnetite nanoparticles (Fe3O4@SiO2) through condensation reaction between 3-aminopropyl triethoxysilane and 2-hydroxy1-naphthaldehyde and succeeding reaction with dioxomolybdenum(VI) acetylacetonate (MoO2(acac)2). The synthesized cat...

Chalcones are the condensation product of acetophenone in combination with aromatic aldehydes in the presence of strong base. Chalcones and their metal complexes having prominent role in modern coordination chemistry. These compounds possessing novel structural features, interesting spectral and magnetic properties, have been the subject of intensive research due to their importance in medical,...
