The asymmetric exclusion process: Comparison of update procedures

open access: yes, 1997
The asymmetric exclusion process (ASEP) has attracted a lot of interest not only because its many applications, e.g. in the context of the kinetics of biopolymerization and traffic flow theory, but also because it is a paradigmatic model for ...

From “Passive Supplementation” to “Active Repair”: Melatonin Reshapes the Treatment Paradigm for Late‐Onset Hypogonadism by Targeting Leydig Cell Senescence

open access: yesAging Cell, Volume 25, Issue 5, May 2026.
Melatonin restores testosterone production in aging Leydig cells by targeting key pathological drivers, particularly oxidative stress and mitochondrial dysfunction. This approach offers a fundamental strategy to reshape the Late‐onset hypogonadism treatment paradigm.

Biological Degradation of Phthalates: From Bioremediation to Plastic Waste Valorization

open access: yesChemSusChem, Volume 19, Issue 7, 14 April 2026.
Phthalic acid isomers play a key role in the plastics industry, but pose significant environmental and health concerns. This review explores the microbial biodegradation of phthalates and their esters, focusing on bacterial enzymes, catabolic pathways, and cellular uptake mechanisms of phthalates.

Di(2-ethylhexyl)phthalate (DEHP) and di-n-butylphthalate (DBP) exposure through diet in hospital patients. [PDF]

open access: yes, 2013
Ready-to-eat packed meals intended to hospital patients were studied over a two-weeks period to measure the contents of di-(2-ethylhexyl) phthalate (DEHP) and di-n-butylphthalate (DBP) and to evaluate their daily intake by total diet.

Children's exposure to Di(2-ethylhexyl)phthalate and dibutylphthalate plasticizers from school meals. [PDF]

open access: yes, 2011
Packed school meals for children 310 years old were studied to evaluate the levels of di(2-ethylhexyl)phthalate (DEHP) and di-n-butylphthalate (DBP) and the influence of the packaging process on meal contamination, and their contribution to daily ...
