The first detection of Leishmania major in naturally infected Sergentomyia minuta in Portugal [PDF]

, 2013
Phlebotomine sandflies of the genus Sergentomyia are widely distributed throughout the Old World. It has been suggested that Sergentomyia spp are involved in the transmission of Leishmania in India and Africa, whereas Phlebotomus spp are thought to be ...

RanBP2-Mediated SUMOylation Promotes Human DNA Polymerase Lambda Nuclear Localization and DNA Repair [PDF]

, 2020
Cellular DNA is under constant attack by a wide variety of agents, both endogenous and exogenous. To counteract DNA damage, human cells have a large collection of DNA repair factors. Among them, DNA polymerase lambda (Polλ) stands out for its versatility,

In Vitro Evaluation of Novel Calcium Silicate‐Based and Resin‐Modified Calcium Silicate Materials: Cytocompatibility and Mineralization Potential on Human Dental Pulp Stem Cells for Pulp Repair

Microscopy Research and Technique, EarlyView.
This study demonstrates that Biodentine XP exhibits superior cytocompatibility, promotes odontogenic differentiation, and enhances mineralization in human dental pulp stem cells, supporting its use in regenerative endodontics. Resin‐modified materials showed lower bioactivity, highlighting the importance of material composition in pulp therapy outcomes.

Secrets within stems: The cryptic Apodanthes caseariae (Apodanthaceae), a rare neotropical holoendoparasite

PLANTS, PEOPLE, PLANET, EarlyView.
Holoendoparasites are extremely rare plants that live entirely hidden inside their hosts, with only flowers and fruits visible. We studied Apodanthes caseariae, found in central and South America, parasitizing Casearia sylvestris. Little is known about its life cycle.

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.

Dendrimeric Antigens for Passive Mast Cell Activation in the Evaluation of Amoxicillin Allergy

Allergy, EarlyView.
DeAns with defined nanoscale structure reveal that conjugate size and determinant density govern IgE‐mediated effector‐cell activation in AX allergy. All DeAn generations bind to sIgE in inhibition immunoassay, but only larger DeAns trigger FcεRI‐dependent responses in mouse MC, huRBL‐2H3, and LUVA cells.
