Unraveling the active site cover of coproheme decarboxylase from Listeria monocytogenes

open access: yesThe FEBS Journal, EarlyView.
During heme biosynthesis in Gram‐positive bacteria, coproheme decarboxylase (ChdC) catalyzes the conversion of four‐propionate substrate coproheme to the two propionate product heme b. Its active site is universally covered by a flexible linking loop. This study identifies an important histidine residue, which stabilizes the loop in a ChdC homolog.

Performance of Automated Hematology Analyzer Criteria in Detecting Peripheral Blood Smear Abnormalities: A Systematic Literature Review

open access: yesInternational Journal of Laboratory Hematology, EarlyView.
ABSTRACT Objectives Criteria for visual examination of stained peripheral blood smear (PBS) differ among institutions in the United States and internationally. In an effort to standardize review criteria, the International Consensus Group for Hematology Review (ICGHR) proposed in 2005 a consensus list of rules for CBC findings that should trigger a ...

Phenotypic scoring of canola blackleg severity using machine learning image analysis

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Canola blackleg is a fungal disease that causes significant yield loss and plant death of infected canola (Brassica napus L., Brassica rapa L., Brassica juncea L.) fields worldwide. One of the most effective methods for controlling blackleg is through the cultivation of resistant varieties.

Influence of Storage Time on Functional Bulk Properties of Low‐Pressure Oxygen/Argon Plasma Modified Polypropylene Fabric

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 33, September 5, 2026.
Treatment of polypropylene fabric in oxygen plasma was used to impart the fabric surface with more hydrophilic surface properties. Changes in bulk properties were minimal as the modification mainly affected the fabric surface. Bulk fabric properties water retention, moisture content and wicking were monitored over a period of 33 days.

mGluR5 in ECCCK to BLA Circuit Modulates Depressive‐Like Phenotypes through CCK Signaling

open access: yesAdvanced Science, Volume 13, Issue 43, 3 August 2026.
Dysregulation of mGluR5 and CCK signaling contributes to major depressive disorder, yet circuit‐level mechanisms remain unclear. Here, the ECCCK→BLA pathway is identified as a critical regulator of affective behavior. mGluR5 modulates synaptic function and CCK signaling within this circuit, controlling stress susceptibility and depressive‐like states ...

GK PUA Domain Modulates Cables, Cooperativity, and Proline Feedback

open access: yesAggregate, Volume 7, Issue 8, August 2026.
EcGK tetramers hierarchically assemble into metabolic filaments and bundle into metabolic cables. Upon substrate binding, this dynamic equilibrium shifts from inactive cables to active tetramers to drive catalysis; meanwhile the inhibitor proline stabilizes an X‐shaped conformation, redirecting assembly toward filaments to enable efficient feedback ...

An Olfactory Piriform Cortex‐Lateral Hypothalamus Neural Circuit Contributes to Linalool‐Induced Analgesia

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 8, August 2026.
Linalool odor exposure activates a glutamatergic projection from the piriform cortex to the lateral hypothalamus (PiriGlu‐LH), mediating descending inhibitory pain pathways. This demonstrates a novel neural mechanism for olfactory‐induced pain modulation and suggests potential therapeutic implications for pain management.

Cleaning Efficacy of Air Polishing on Tobacco‐Stained Resin Composite: An In‐Vitro Study

open access: yesClinical and Experimental Dental Research, Volume 12, Issue 4, August 2026.
ABSTRACT Objective To evaluate the efficacy of air‐polishing on color change and surface roughness of resin composite and enamel specimens after standardized cigarette smoke exposure. Methods Sixty composite/enamel specimens were exposed daily to cigarette smoke in an automated chamber over four 14‐day cycles (five cigarettes/day).
