Extending evolutionary forecasts across bacterial species.

Improving evolutionary forecasting requires progressing from studying repeated evolution of a single genotype under identical conditions to formulating broad principles. These principles should enable predictions of how similar species will adapt to similar selective pressures. Evolve-and-resequence experiments with multiple species allow testing forecasts on different biological levels and elucidating the causes for failed predictions.

Pancreatic Adenocarcinoma: Long-Term Outcomes of Adjuvant Therapy in the ESPAC4 Phase III Trial.

Purpose: The ESPAC4 trial showed that adjuvant chemotherapy with gemcitabine plus capecitabine (GemCap) produced longer overall survival (OS) than gemcitabine monotherapy. Subsequently, the PRODIGE24-CCTG PA.6 trial showed even longer survival for modified fluorouracil, folinic acid, irinotecan, and oxaliplatin (mFOLFIRINOX) than gemcitabine but had more restrictive eligibility criteria.

The effect of polygenic liability to mental disorders on COVID-19 outcomes in people with depression: the mediating role of anxiety.

Background: Genetic vulnerability to mental disorders has been associated with coronavirus disease-19 (COVID-19) outcomes. We explored whether polygenic risk scores (PRSs) for several mental disorders predicted poorer clinical and psychological COVID-19 outcomes in people with pre-existing depression.

Methods: Data from three assessments of the Australian Genetics of Depression Study ( = 4405; 52.

The mouse monoclonal antibody 4E3 is specific for the G1m17 allotype of human IgG1.

Allotype is an amino acid variation within the immunoglobulin isotypes. Four allotypes have been described for human IgG1 and two of them (G1m3 and G1m17) are located at position 214 in the CH1 region of the gamma chain. Various diseases have been associated with allotype expression, making the allotype research an interesting field in immunology.
