Effect of MEHP on testosterone synthesis via Sirt1/Foxo1/Rab7 signaling pathway inhibition of lipophagy in TM3 cells

Ecotoxicology and Environmental Safety
Mono-2-ethylhexyl phthalic acid (MEHP) is the most toxic metabolite of the plasticizer di-2-ethylhexyl phthalic acid (DEHP), and studies have shown that MEHP causes serious reproductive effects. However, its exact mechanisms of action remain elusive.

Mix‐to‐Prepare Dicarboxylic Acid‐Based Decoy Molecules Enable Wild‐Type P450BM3‐Catalyzed Oxidation of Non‐Native Substrates

ChemCatChem, Volume 18, Issue 9, 14 May 2026.
Amic acid‐based decoy molecules were developed by simple mixing of acid anhydrides and amines. The newly identified phthalic acid‐based decoy molecules enabled whole‐cell benzene hydroxylation by cytochrome P450BM3, achieving phenol production about 3 mM, without the need for prior complex chemical synthesis and purification of the decoy molecules ...

Disentangling the Multifactorial Influences on Diabetes Risk Among Rural Communities: Food Environment, Diet Quality, and Dietary Chemical Exposures

Diabetes/Metabolism Research and Reviews, Volume 42, Issue 4, May 2026.
ABSTRACT Aims Rural communities experience a higher prevalence of type 2 diabetes and diabetes‐related mortality than urban populations. This study sought to disaggregate the influences of demographic and socioeconomic factors, food environment, diet quality, and dietary chemical exposures on diabetes risk in rural areas.

Phthalates and Mixed Alkyl Phthalates Analysis in Plastics Using GC‐MS With Cold EI

Journal of Mass Spectrometry, Volume 61, Issue 5, May 2026.
ABSTRACT Phthalates are esters of phthalic acid. They are widely used as plasticizers to improve the flexibility, durability, and performance of plastics in a variety of products. However, certain phthalates are associated with significant health risks, including endocrine disruption and reproductive toxicity.

The benzene polycarboxylic acid (BPCA) pattern of wood pyrolyzed between 200°C and 1000°C [PDF]

, 2010
Environmental charcoals represent a poorly defined part of the black carbon (BC) combustion continuum and may differ widely in their chemical and physical properties, depending on combustion conditions and source material. The benzene polycarboxylic acid
