Prolonged Turnaround Time of the Hematology Laboratory and Related Factors in the South Gondar Zone, North West Ethiopia, Multi‐Centered Study

Journal of Clinical Laboratory Analysis, EarlyView.
Long turnaround times were prevalent in the hematology laboratories of South Gonder zone hospitals, predominantly as a result of staff incompetence. Clotted blood samples, low blood fill levels, and the day of the week were significant factors linked to delays, with samples collected on Friday having a higher likelihood of prolonged turnaround time ...

Egg yolk hydrolysate shows moderate impact on osteoporosis in ovariectomized rats

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND This study investigated the protective effect of egg yolk hydrolysate (FC) on osteoporosis in ovariectomized (OVX) rats, a well‐established model of postmenopausal bone loss. OVX rats were fed diets supplemented with 0.2% or 1% FC for 13 weeks.

Atmospheric Chemistry of CFH2CH2CH2CFH2: Kinetics and Mechanism of Reactions With Cl Atoms and OH Radicals

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT The atmospheric chemistry of 1,4‐difluorobutane (CFH2CH2CH2CFH2) was investigated through a kinetic and mechanistic study of the reaction with chlorine (Cl) atoms and hydroxyl (OH) radicals. Using Fourier transform infrared (FTIR) spectroscopy and relative rate methods, the rate constants (k) for the reactions were determined at 298 ± 2 K as k(

Genome‐wide screen reveals a universal role of ATP in ciprofloxacin tolerance among genetically distinct Escherichia coli persisters

mLife, EarlyView.
Abstract Bacterial persisters show tolerance to bactericidal antibiotics and play essential roles in chronic infections; however, the general mechanisms underlying persister formation and antibiotic tolerance remain insufficiently characterized. In this study, the Escherichia coli Keio library was used to identify genes involved in ciprofloxacin ...

Made in the shade: Leaf responses of native wildflowers to single‐axis photovoltaic solar energy

PLANTS, PEOPLE, PLANET, EarlyView.
As solar energy expands globally, balancing renewable power generation with biodiversity and ecosystem health has become an urgent challenge. This study investigated how native wildflowers respond at leaf level to the unique microclimates created by rotating solar panels in California's Central Valley.

Snapshots of Motion: A Novel Structural Intermediate Reveals Conserved Dynamics in Archaeal DNA Ligases

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT We present the first x‐ray crystallographic structural evidence of an archaeal DNA ligase showing the AMP covalent adduct together with further cofactor hydrolysis, capturing a transient intermediary in the first step of the ligation reaction, triggered by the pyrophosphate hydrolysis.

The X‐Ray Crystal Structure of BorF, the Flavin Reductase Subunit of a Two‐Component Flavin‐Dependent Tryptophan Halogenase

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT BorF is a short‐chain flavin reductase from a desert soil bacterium that uses NADH to reduce FAD to FADH2, which is used by the tryptophan‐6‐halogenase BorH to chlorinate tryptophan in the biosynthetic pathway of borregomycin A. The X‐ray crystal structure of BorF bound to FAD was solved to 2.37 Å by molecular replacement.
