Stomatal distribution and post‐fire recovery: Intra‐ and interspecific variation in plants of the pyrogenic Florida scrub

American Journal of Botany, EarlyView.
Abstract Premise Amphistomy, the presence of stomata on both leaf surfaces, can increase photosynthesis yet is uncommon across vascular plants. The relative infrequency of amphistomy is often attributed to high costs, such as transpirational water loss.

Establishment patterns of saguaro cactus (Carnegiea gigantea) at the microsite scale help explain saguaro regeneration and distributions in heterogenous, regional habitats

American Journal of Botany, EarlyView.
Abstract Premise Establishment of long‐lived perennial plants is a pivotal event that often leads to reproductive maturity. The population dynamics of the giant saguaro cactus (Carnegiea gigantea) have been investigated over large spatial areas, but establishment patterns have not been studied at the microsite (1 m) scale.

Seguir adelante: A qualitative exploration of Latino farmworkers' work and nonwork resources

American Journal of Community Psychology, EarlyView.
Abstract Latino immigrant workers have been an exploited community within many dangerous workforces, but especially within the agricultural industry. They are a crucial population for the labor and economy of the U.S., yet Latino farmworkers report feeling expendable, discriminated against, and exposed to hazardous working conditions.

Medical Surveillance of Occupational Lead Exposure Using the EPA's Toxics Release Inventory and Adult Blood Lead Epidemiology and Surveillance Program: Illinois, 2016–2023

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Background Despite existing regulations mandating exposure control, training, and monitoring, many worksites continue to inadequately protect workers from lead exposure. The Environmental Protection Agency (EPA) requires facilities to report lead emissions to the Toxics Release Inventory (TRI), presenting a potential tool for identifying at ...

Improved husbandry measures to enhance reproducibility of wound healing studies in the Leprdb/db mouse

Animal Models and Experimental Medicine, EarlyView.
Though the Leprdb/db mouse is a common and well‐studied model of type II diabetes mellitus, there are a few specific guidelines for its husbandry, and wound complications are common. We present a modified husbandry approach for the Leprdb/db mouse that includes increased cage size, decreased housing density, and more frequent cage changes.

Structural Basis of Sequential Enantioselective Epoxidation by a Flavin‐Dependent Monooxygenase in Lasalocid A Biosynthesis

Angewandte Chemie, EarlyView.
Lsd18 is a flavin‐dependent monooxygenase from Streptomyces lasalocidi that performs two enantioselective epoxidations during lasalocid A biosynthesis. X‐ray crystal structures of Lsd18 bound to a substrate and product analogue illuminate how this enzyme performs multiple epoxidations on the same substrate molecule and how it controls stereoselectivity.

Rapid Access to an Enantioenriched Spiro Bisindole Directly from Indole and Acetone

Angewandte Chemie, EarlyView.
A catalytic enantioselective one‐pot “self‐assembly” strategy was developed for the exceedingly convenient access to a spiro bisindole directly from indole and acetone. The obtained enantiopure C2‐symmetric bisindole showed exceptional performance as a chiral backbone of diverse effective catalysts or ligands. Abstract Disclosed here is a “one‐pot self‐
