Estrogen-related receptor alpha drives mitochondrial biogenesis and resistance to neoadjuvant chemoradiation in esophageal cancer.

Neoadjuvant chemoradiotherapy (nCRT) improves outcomes in resectable esophageal adenocarcinoma (EAC), but acquired resistance precludes long-term efficacy. Here, we delineate these resistance mechanisms. RNA sequencing on matched patient samples obtained pre-and post-neoadjuvant treatment reveal that oxidative phosphorylation was the most upregulated of all biological programs following nCRT.

Diffuse large B-cell lymphoma with MYC gene rearrangements: Current perspective on treatment of diffuse large B-cell lymphoma with MYC gene rearrangements; case series and review of the literature.

In the past decade, patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL) were treated with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone) therapy. Standard treatment is now changing as a result of deeper understanding of underlying biologic differences of such lymphomas. One of the most powerful predictors of an adverse outcome on R-CHOP therapy is the presence of a MYC gene rearrangement (MYC+ lymphoma).

Imported human trichinellosis: sequential IgG4 antibody response to Trichinella spiralis.

Two out of five members of one household presented with clinical signs of trichinellosis after their return to the Netherlands. The family had consumed Trichinella-infected pork in Montenegro, formerly Yugoslavia. Serological tests were performed at 1, 2, 6, and 18 months after ingestion of the infected meat.

Chlorinated organic contaminants in breast milk of New Zealand women.

Breast milk samples from 38 women in New Zealand were analyzed for organochlorine pesticides, polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs), and polychlorinated dibenzofurans (PCDFs) as part of a World Health Organization collaborative study of breast-milk contaminants. The women were recruited from two urban areas (Auckland and Christchurch) and two rural areas (Northland and North Canterbury) in the North and South Islands of New Zealand. The best predictor of contaminant concentrations in breast milk was found to be the age of the mother.
