Single-Cell Peptide Profiling to Distinguish Stickleback Ecotypes with Divergent Breeding Behavior.

Variation in parenting behavior is widespread across the animal kingdom, both within and between species. There are two ecotypes of the three-spined stickleback fish () that exhibit dramatic differences in their paternal behavior. Males of the common ecotype are highly attentive fathers, tending to young from eggs to fry, while males of the white ecotype desert offspring as eggs.

Longer Total Interhospital Transfer Times for Rural Sepsis Patients Not Associated with Increased Mortality.

Objectives: Sepsis is a time-sensitive condition, and many rural emergency department (ED) sepsis patients are transferred to tertiary hospitals. The objective of this study was to determine whether longer transport times during interhospital transfer are associated with higher sepsis mortality or increased hospital length-of-stay (LOS).

Methods: A cohort of rural adult (age ≥ 18y) sepsis patients transferred between hospitals were identified in the TELEmedicine as a Virtual Intervention for Sepsis Care in Emergency Departments (TELEVISED) parent study.

Ring Fixator Bone Transport is Associated With Fewer Unplanned Major Reoperations than Masquelet in the Treatment of Segmental Bone Defects of the Tibia.

Objective: To determine whether bone transport or Masquelet results in higher rates of major unplanned reoperations for the treatment of segmental tibial bone defects ≥4 cm in length.

Methods: Design: Retrospective cohort.

Setting: Level I trauma center.

Effects of Cofeeding Hydrogen on Propane Dehydrogenation Catalyzed by Isolated Iron Sites Incorporated into Dealuminated BEA.

Iron sites dispersed on nonacidic siliceous supports have been reported to be catalytically active for propane dehydrogenation (PDH), yet the precise relationship between site structure and catalytic activity remains elusive. This study provides a comprehensive understanding of the catalytic performance of iron supported on dealuminated BEA (DeAlBEA) zeolites for PDH. Using XAS, UV-vis, and IR spectroscopy of adsorbed pyridine and deuterated acetonitrile, it was found that, at an Fe/Al of 0.

Teaching Preclinical Medical Students Lifestyle Counseling Skills for Patients' Health Behavior Change.

Introduction: Physicians face barriers to counseling patients regarding lifestyle, specifically, low perceived importance of and confidence in counseling, leading to underuse. There is a dearth in the literature evaluating educational interventions for counseling skills among preclinical medical students. Closing this gap is crucial to taking advantage of critical opportunities early in training.
