Investigating the optimal amount of chlorine consumption in the disinfection of the effluent of the Arak sewage treatment plant [PDF]

رویکردهای نوین در مهندسی آب و محیط زیست
Since chlorine is a highly toxic substance, if it is combined with organic elements in the wastewater, it causes the creation of odorous compounds and causes the creation of byproducts in the wastewater, and some of them are known as carcinogenic ...

Biogeochemical cycles of chlorine in the coniferous forest ecosystem: practical implications

Plant, Soil and Environment, 2010
Chlorine - one of the most widespread elements on the Earth - is present in the environment as chloride ion or bound to organic substances. The main source of chloride ions is the oceans while organically bound chlorine (OCl) comes from various sources ...

Syntheses and Glycosidase Inhibitory Activities, and in Silico Docking Studies of Pericosine E Analogs Methoxy-Substituted at C6

Marine Drugs, 2020
Inspired by the significant α-glucosidase inhibitory activities of (+)- and (−)-pericosine E, we herein designed and synthesized 16 analogs of these marine natural products bearing a methoxy group instead of a chlorine atom at C6. Four of these compounds

Secondary organic aerosol from chlorine-initiated oxidation of isoprene [PDF]

Atmospheric Chemistry and Physics, 2017
Recent studies have found concentrations of reactive chlorine species to be higher than expected, suggesting that atmospheric chlorine chemistry is more extensive than previously thought.

Data on the level of haloacetic acids in indoor swimming pools of Iran: A case study of Tehran

Data in Brief, 2018
Haloacetic acids (HAAs) are the second most prevalent class of DBPs after trihalomethanes (THMs) in water disinfected by chlorine compounds. Within this study, we present new data on occurrence and speciation of HAA levels in 15 indoor swimming pools in ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

FEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Effect of Bromide Ions on the Transformation of Natural Organic Matter and the Formation of Halogenated Byproducts in the UV/chlorine Oxidation Process

能源环境保护
The UV/chlorine advanced oxidation process (AOP), which generates various highly reactive radical species, effectively degrades micropollutants and inactivates microorganisms.

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.
