Maryam Sadat Ghasemzadeh was born in Ghaen/ Southern Khorasan, Iran. She received her B.Sc. in Pure Chemistry from Imam Khomeini International University and M.Sc. in Organic Chemistry from Birjand University under the supervision of Professor Sara Sobhani. She is currently studying her Ph.D. in Ferdowsi University of Mashhad under the supervision of Professor Batool Akhlaghinia. Her current re...

Proteochemometrics was applied in the analysis of the binding of organic compounds to wild-type and chimeric melanocortin receptors. Thirteen chimeric melanocortin receptors were designed based on statistical molecular design; each chimera contained parts from three of the MC(1,3-5) receptors. The binding affinities of 18 compounds were determined for these chimeric melanocortin receptors and t...

Many classes of odorants and volatile organic compounds that are deleterious to our wellbeing can be emitted from diverse cooking activities. Once emitted, they can persist in our living space for varying durations. In this study, various volatile organic compounds released prior to and during the pan frying of fish (mackerel) were analyzed at three different cooking stages (stage 1 = raw (R), ...

OBJECTIVES The purpose of this study was to measure the concentration of volatile organic compound (VOC)s originated from the chemicals used and/or derived from the original parental chemicals in the photolithography processes of semiconductor manufacturing factories. METHODS A total of four photolithography processes in 4 Fabs at three different semiconductor manufacturing factories in Korea...

Mesoporous organic-inorganic hybrid materials, a new class of materials characterized by large specific surface areas and pore sizes between 2 and 15 nm, have been obtained through the coupling of inorganic and organic components by template synthesis. The incorporation of functionalities can be achieved in three ways: by subsequent attachment of organic components onto a pure silica matrix (gr...

Introduction: A major goal of the Mars Science Laboratory (MSL) mission is to search for past and present habitable environments at Gale crater [1]. To achieve this goal MSL has, in particular, the capability to detect complex organic molecules in rocks and soils using the Sample Analysis at Mars instrument (SAM). A primary goal of the SAM investigation is to carry out a search for organic comp...

BACKGROUND Previous research has shown exposure to air pollution increases the risk of adverse birth outcomes, although the effects of residential proximity to significant industrial point sources are less defined. The objective of the current study was to determine whether yearly reported releases from major industrial point sources are associated with adverse birth outcomes. METHODS Materna...

Few reports have characterized mutagenic compounds in respirable airborne particles (<2.5 micrometers in diameter; PM2.5) collected at different sites on a regional scale (hundreds of km). Previously, we reported differences in the human (h1A1v2) cell mutagenicity of whole and fractionated organic extracts of PM2.5 samples collected in Boston, MA, Rochester, NY, and Quabbin Reservoir, a rural s...
