Tributyltin Protumorigenic Effects Targeting Prostate Cancer Cell Metabolism, Proliferation, Migration, and Invasion

open access: yesEnvironmental Toxicology, Volume 41, Issue 9, Page 709-729, September 2026.
ABSTRACT Prostate cancer (PCa) is an endocrine‐related cancer highly dependent on androgenic signaling. Beyond hormone dependence, extrinsic factors play a significant role in the risk of developing PCa, which raises concern about the influence of environmental compounds such as endocrine‐disrupting chemicals (EDCs). Tributyltin (TBT) is an EDC used in

Cannabinoid and adenosine A2A receptor crosstalk regulates postnatal and adult hippocampal neurogenesis

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 18, Page 5440-5457, September 2026.
Background and purpose Adult neurogenesis is a tightly regulated process affected by both cannabinoid receptors (CB1 and CB2) and adenosine 2A (A2A) receptors, both of which modulate neural progenitor cell activity. While emerging evidence suggests an interaction between these neuromodulatory systems, the extent and mechanism of their interplay in ...

Gardiquimod Nanoemulsion Targets Cutaneous Leishmaniasis Lesions Reducing Systemic Toxicity and Parasite Burden

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 30, 14 August 2026.
Nanoemulsion delivery of a TLR7 agonist enhances safety and promotes colocalization with Leishmania‐infected macrophages in skin lesions, enabling a ∼2‐log reduction in parasite burden. However, tissue‐level constraints and TLR‐driven regulatory feedback generate a mixed immune response that limits complete parasite clearance.

Nutritional Value of Biofloc Meal for White Cachama (Piaractus orinoquensis): Effects of Inclusion Level on Digestibility, Growth Performance, and Protein Retention

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 4, August 2026.
ABSTRACT Biofloc technology (BFT) offers a sustainable aquaculture strategy; however, the value of its byproduct, biofloc meal (BFM), as a feed ingredient requires validation for key species. This study evaluated the use of BFM from a tilapia–molasses system as a feed ingredient for white cachama (Piaractus orinoquensis) juveniles.
