Mercury and selenium in biological pump under upwelling-downwelling influence in Cabo Frio shelf, South Atlantic Ocean, Brazil.

The knowledge of metals concentration in upwelling areas are a concern due the higher productivity of these areas In Cabo Frio Upwelling-Downwelling System (CFUS) is high primary productivity area and has been identified as an Hg hotspot to biota in SE Brazil that has been susceptible to Hg inputs, due to growing industrialization in the region. To investigate the concentration of Hg and Se metals, as well as the trophic transfer of these metals, the present study investigated Hg and Se concentrations in 64 samples collected in net mesh of >20, >64, >150 and >300 μm, in 2012, in the region's water masses. Higher mean Hg concentrations were found in zooplankton, 0.

Two-Stage Mayo Clinic Class IIIb Celiac Axis Resection for Pancreatic Adenocarcinoma: Stepwise Management.

Background: The National Comprehensive Cancer Network guidelines consider pancreatic cancer with celiac axis (CA), proper hepatic artery (PHA), and superior mesenteric artery (SMA) involvement unresectable. Thus, technical reports and video illustrations of these operations are rare. We report the stepwise management of multivascular reconstruction for Mayo Clinic class IIIb CA resections at New York University Langone Health, a dedicated center of excellence in pancreatic surgery.

Development of a Composite Score Based on Carbohydrate Antigen 19-9 Dynamics to Predict Survival in Carbohydrate Antigen 19-9-Producing Patients With Pancreatic Ductal Adenocarcinoma After Neoadjuvant Treatment.

Purpose: Dynamics of carbohydrate antigen 19-9 (CA19-9) often inform treatment decisions during and after neoadjuvant chemotherapy (NAT) of patients with pancreatic ductal adenocarcinoma (PDAC). However, considerable dispute persists regarding the clinical relevance of specific CA19-9 thresholds and dynamics. Therefore, we aimed to define optimal thresholds for CA19-9 values and create a biochemically driven composite score to predict survival in CA19-9-producing patients with PDAC after NAT.
