Bisphenols and Phthalates in Bottled Mineral Water: First Evidence of Co‐Occurrence, Estrogenic Activity, and Health Risk in Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA), its structural analogs, and phthalates are synthetic chemicals widely used, with documented endocrine‐disrupting activity. This study aimed to develop and validate a selective multiresidue analytical method for the simultaneous determination of BPA, 10 bisphenol analogs, and six phthalates in PET‐bottled mineral water.

Gas check prevention during calendering of poly(vinyl chloride) films using poly(caprolactone)‐based additives

Journal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 441-452, March 2025.
Three poly(caprolactone) (PCL)‐based additives of differing molecular weights were used as a secondary plasticizer to prevent gas checks in PVC films produced through calendering. Results showed that chemical and physicochemical properties influence the prevention or reduction of gas checks, unlike rheological properties including complex viscosity and

Thermal Degradation and Thermal Decomposition of Plasticized PVC Including POSS Additives for PVC Compounds: Mechanisms, Impact, and Performance of Standards

Journal of Vinyl and Additive Technology, EarlyView.
Additives' structures. ABSTRACT Poly(vinyl chloride) has been a key polymeric material since its commercial production in 1931, demonstrating versatility across numerous industries due to its compatibility with various additives. PVC's inherent properties, flame retardance, durability, and recyclability make it ideal for building and construction ...

The role of iron in normal and impaired testicular function

Andrology, EarlyView.
Abstract Iron plays a critical role in testicular physiology, impacting spermatogenesis, testosterone production, and overall testicular function. Iron homeostasis is maintained through systemic and cellular regulatory mechanisms, including hepcidin‐mediated systemic iron control and the iron‐responsive element/iron regulatory protein (IRE/IRP) system ...

Contact sensitisers activate keratinocytes and induce cytotoxicity via Transient Receptor Potential Ankyrin 1 in allergic contact dermatitis

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Allergic contact dermatitis (ACD) is a frequent inflammatory skin disease with limited therapeutic options. While neuronal Transient Receptor Potential Ankyrin 1 (TRPA1) has been implicated in ACD, the role of keratinocyte TRPA1 remains unclear.

Occurrence and Washout of Health‐Hazardous Chemicals in Children's Clothing

Contact Dermatitis, EarlyView.
A survey of 60 children's garments from the Swedish market showed a varying, often highly complex chemical content. The highest levels were generally found in synthetic materials and the lowest in light‐coloured cotton. Further, the washout effect by laundry and sweat migration of textile chemicals was investigated.

Abnormal cleavage patterns in equine in vitro‐produced embryos lead to higher early pregnancy loss

Equine Veterinary Journal, EarlyView.
Summary Background Despite significant advances, in vitro production (IVP) of equine embryos continues to lack standardised embryo classification criteria and is associated with increased rates of early pregnancy loss compared with in vivo‐derived blastocysts.

Shedding light on the parasite communities and diet of the deep‐sea shark Deania profundorum (Smith & Radcliffe, 1912) (Squaliform: Centrophoridae) from the Avilés Canyon (southern Bay of Biscay)

Journal of Fish Biology, EarlyView.
Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and
