Exposure to Endocrine Disruptors and Nuclear Receptors Gene Expression in Infertile and Fertile Men from Italian Areas with Different Environmental Features [PDF]

open access: yes, 2015
Internal levels of selected endocrine disruptors (EDs) (i.e., perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), di-2-ethylhexyl-phthalate (DEHP), mono-(2-ethylhexyl)-phthalate (MEHP), and bisphenol A (BPA)) were analyzed in blood/serum of ...

Sodium Tanshinone IIA Sulfonate Attenuates Tumor Oxidative Stress and Promotes Apoptosis in an Intermittent Hypoxia Mouse Model

open access: yesTechnology in Cancer Research & Treatment, 2020
Objective: Intermittent hypoxia, a significant feature of obstructive sleep apnea, has pro-tumorigenic effects. Here, we investigated the effect of sodium tanshinone IIA sulfonate on oxidative stress and apoptosis in a mouse model of Lewis lung carcinoma

Physico-chemical characterization of bilirubin-10-sulfonate and comparison of its acid–base behavior with unconjugated bilirubin

open access: yesScientific Reports, 2021
Unconjugated bilirubin (UCB) is the end-product of heme catabolism in the intravascular compartment. Although beneficial for human health when mildly elevated in the body, when present at greater than a critical threshold concentration, UCB exerts toxic ...

Benzhydryl phenyl sulfone [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2009
In the title compound, C(19)H(16)O(2)S, the sulfur-bound phenyl group is approximately parallel to one of the two phenyl rings of the benzhydryl group, making a dihedral angle of 12.53 (10)°, and forms a dihedral angle of 41.25 (9)° with the other phenyl ring. In the crystal, weak C-H⋯O inter-actions form a two-dimensional network propagating along the

Homopolymer self-assembly of poly(propylene sulfone) hydrogels via dynamic noncovalent sulfone–sulfone bonding [PDF]

open access: yesNature Communications, 2020
Abstract Natural biomolecules such as peptides and DNA can dynamically self-organize into diverse hierarchical structures. Mimicry of this homopolymer self-assembly using synthetic systems has remained limited but would be advantageous for the design of adaptive bio/nanomaterials.
