Generating distant analogies increases metaphor production.

Although a large body of work has explored the mechanisms underlying metaphor comprehension, less research has focused on spontaneous metaphor production. Previous research suggests that reasoning about analogies can induce a relational mindset, which causes a greater focus on underlying abstract similarities. We explored how inducing a relational mindset may increase the tendency to use metaphors to describe topics.

Acute perioperative alterations in metabolism: A pilot study using mass spectrometry-based metabolomics.

Objective: To characterize early physiologic stresses imposed by surgery by applying metabolomic analyses to deeply phenotype pre- and postoperative plasma and urine of patients undergoing elective surgical procedures.

Background: Patients experience perioperative stress through depletion of metabolic fuels. Bowel stasis or injury might allow more microbiome-derived uremic toxins to enter the blood, while the liver and kidney are simultaneously clearing analgesic and anesthetic drugs.

Clinical Applications of Bone Marrow CD34 Immunohistochemistry (BM CD34 IHC) Assay: International Council for Standardization in Hematology (ICSH) Guidelines.

Introduction: Investigation of bone marrow (BM) trephine biopsies and/or clot sections by CD34 immunohistochemistry (IHC) testing has been used by pathologists for several decades, and its clinical value has been well established with QBEND10 being the most frequently used primary antibody (Ab) clone. However, most other parameters related to the IHC protocol as well as the readout vary widely between clinical laboratories and in the published literature. The ICSH Working Group having reviewed the published evidence has established guidelines that will help to harmonize performance and reporting of CD34 IHC on BM biopsies.
