Association between organophosphate pesticide exposure and atopic dermatitis: a cross-sectional study based on NHANES 1999-2007.

Background: Organophosphate pesticides (OPPs) are widely used environmental chemicals with potential health impacts, but their relationship with atopic dermatitis (AD) remains unclear.

Methods: Using data from the National Health and Nutrition Examination Survey (NHANES) 1999-2007, we investigated associations between urinary OPP metabolites and AD in 4,258 adults. Six dialkyl phosphate (DAP) metabolites were measured, and weighted quantile sum (WQS) regression was used to assess mixture effects.

Pancreatic cancer differential methylation atlas in blood, peri-carcinomatous and diseased tissue.

Background: Pancreatic cancer is common in elderly persons, and less than 20% of patients present with localized, potentially curable tumors.

Methods: We compared the methylated sites and genes in pericarcinous tissues compared to cancer tissue, and blood compared to pericarcinous tissues in order to harvest methylation markers for putative diagnostic and therapy monitoring purposes.

Results: Of 15,397 CpG sites detected in 7,440 genes, 5,605 (36.

Targeting Phosphorylation of p21-activated Kinase 1 at Thr423 Induces Cell Cycle Arrest and Apoptosis in Cutaneous T-cell Lymphoma Cells.

Cutaneous T-cell lymphoma (CTCL) represents a rare group of extranodal T-cell lymphoproliferative diseases. Due to poor clinical outcome of CTCL, there is an urgent need for new and improved therapies. A small molecule, IPA-3, which inhibits p21-activated kinase 1 (PAK1), has shown therapeutic potential in various types of malignancies.
