Laccase is widely used in several industrial applications and co-culture is a common method for enhancing laccase production in submerged fermentation. In this study, the co-culture of four yeasts with Pleurotus eryngii var. ferulae was found to enhance laccase production. An analysis of sterilization temperatures and extraction conditions revealed that the stimulatory compound in yeasts was te...
BACKGROUND Experimental tools for studying the complex steroidogenic interactions that occur between placenta and fetus during human pregnancy are extremely limited. OBJECTIVES We aimed to develop a co-culture model to study steroidogenesis by the human fetoplacental unit and its disruption by exposure to environmental contaminants. METHODS We cultured BeWo human choriocarcinoma cells, repr...
BACKGROUND: Desflurane and enflurane have been reported to produce substantial amounts of carbon monoxide (CO) in desiccated sodalime. Isoflurane is said to produce less CO and sevoflurane and halothane should produce no CO at all.The purpose of this study is to measure the maximum amounts of CO production for all modern volatile anesthetics, with completely dry sodalime. We also tried to estab...
When incubated in the presence of CO gas, Rubrivivax gelatinosus CBS induces a CO oxidation-H2 production pathway according to the stoichiometry CO + H2O --> CO2 + H2. Once induced, this pathway proceeds equally well in both light and darkness. When light is not present, CO can serve as the sole carbon source, supporting cell growth anaerobically with a cell doubling time of nearly 2 days. This...
This paper studies the modeling and optimization of energy use and greenhouse gas emissions of eggplant production using artificial neural network and multi-objective genetic algorithm in Guilan province of Iran. Results showed that the highest share of energy consumption belongs to diesel fuel (49.24%); followed by nitrogen (33.30%). The results indicated that a total energy input of 13910.67 ...

Carbon monoxide (CO) poisoning causes brain damage, which is attenuated by treatment with hydrogen [1], [2], a scavenger selective to hydroxyl radical (•OH) [3]. This suggests a role of •OH in brain damage due to CO poisoning. Studies have shown strong enhancement of •OH production in rat striatum by severe CO poisoning with a blood carboxyhemoglobin (COHb) level > 70% due to 3000 ppm CO, but n...
objective: in this study, we sought to better understand the immunoregulatory function of stem cells derived from human exfoliated deciduous teeth (shed). we studied the role of the interferon gamma (ifn-γ)-indoleamine 2,3-dioxygenase (ido)-axis in immunoregulation of shed compared to bone marrow derived mesenchymal stem cells (bmmscs) under the same conditions. materials and methods: in this c...
