Increasing X‐ray energy improves data quality in serial crystallography

Journal of Synchrotron Radiation, EarlyView.
Advanced serial crystallography utilizing high‐energy X‐rays enhances diffraction efficiency, data quality and structural resolution under room‐temperature conditions.Serial synchrotron crystallography (SSX) enables structure determination from microcrystals under near‐physiological, room‐temperature conditions but is limited in part due to the ...

Spatial price competition and buyer power in the U.S. beef packing industry

American Journal of Agricultural Economics, EarlyView.
Abstract We develop a spatially‐explicit model of the U.S. beef packing industry to study key questions related to competition in an oligopsony setting. Cattle supplies are modeled at the county level, and packing plants' location, capacity, and ownership are taken as given. Packers procure negotiated cattle by competing in prices in each local (county)

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.

EFEK SONIKASI TERHADAP PROSES PEMBENTUKAN NANOPARTIKEL FE3O4 YANG DIMODIFIKASI DENGAN PEG-6000

Jurnal Teknik Mesin Cakram, 2018
Abstrak: Pada penelitian ini, serbuk nanopartikel magnetit (Fe3O4) dengan penambahan PEG-6000 telah berhasil dipreparasi dengan struktur kubik. Serbuk disintesis pada suhu 70°C dengan metode kopresipitasi dan dilanjutkan proses sonikasi. Serbuk nanopartikel Fe3O4 memiliki dua fasa yaitu Fe3O4 sebagai fasa dominan dan γ-Fe2O3 sebagai fasa minor.

Teleost‐specific ictacalcins exhibit similar structural organization, cation‐dependent activation, and transcriptional regulation as human S100 proteins

The FEBS Journal, EarlyView.
Calcium‐binding S100 proteins are important mediators of inflammation in humans. Distant members of this family have been recently discovered in teleost fish but their resemblance to human proteins has not been explored yet. This study demonstrates that zebrafish‐specific S100i1 and S100i2 (ictacalcins) possess identical structural organization and ...

Unveiling the combined influence of higher molecular weight polyethylene glycol and superplasticizer chemistry on fresh, mechanical, and microstructural performance of internally cured mortar

Materials Research Express
The limitations of conventional water curing in tall structures and arid regions necessitate alternative hydration strategies. Use of internal curing agents in high strength concrete can effectively mitigate evaporation and promote enhanced cement ...

Unexplained Elevated Vitamin B12: Consider Macro‐B12

International Journal of Laboratory Hematology, EarlyView.
ABSTRACT Introduction Elevated vitamin B12 concentration can be caused by supplementation, liver disease, kidney disease, or myeloid malignancies. Persistent, unexplained elevations of vitamin B12 can raise concern among patients and may lead to invasive diagnostic procedures, including bone marrow biopsy.

Enhanced exonuclease–Cas9 systems promote multiple nucleotide deletions with higher efficiency and broader targeting scope in plants

Journal of Integrative Plant Biology, EarlyView.
Cas9 preferentially generates small indels. By tethering an exonuclease and a DNA‐binding domain (DBD) to Cas9, the Exo‐DBD‐Cas9 system efficiently promotes multiple nucleotide deletions. These expanded deletions enable effective disruption of miRNA‐mediated regulation and relieve translational repression through targeted editing of 3′ untranslated ...
