Actin Isovariant ACT2‐Mediated Cellular Auxin Homeostasis Regulates Lateral Root Organogenesis in Arabidopsis thaliana

Cytoskeleton, EarlyView.
ABSTRACT Lateral root (LR) organogenesis is regulated by cellular flux of auxin within pericycle cells, which depends on the membrane distribution and polar localization of auxin carrier proteins. The correct distribution of auxin carrier proteins relies on the intracellular trafficking of these proteins aided by filamentous actin as a track.

Potent monoclonal antibodies against multidrug‐resistant hypervirulent Klebsiella pneumoniae

Interdisciplinary Medicine, EarlyView.
A novel immunization strategy using a low‐virulence, multidrug‐resistant strain yields synergistic monoclonal antibodies against hypervirulent Klebsiella pneumoniae. These antibodies provide cross‐serotype protection through a dual‐mechanism of pathogen clearance and immunomodulation, offering a promising non‐antibiotic therapeutic for resistant ...

Streamlining antibiotic use in community acquired pneumonia: A quality improvement initiative

Journal of Hospital Medicine, EarlyView.
Abstract Background Evidence suggests a 3‐day total duration and early transition to oral therapy is safe in hospitalized patients with community acquired pneumonia (CAP)—though such care is not standard in the United States. To implement these evidence‐based practices, a multidisciplinary group led by a hospitalist and antimicrobial stewardship ...
