Using small-angle X-ray scattering to investigate the compaction behaviour of a granulated clay [PDF]

, 2015
The compaction behaviour of a commercial granulated clay (magnesium aluminium smectite, gMgSm) was investigated using macroscopic pressure-density measurements, X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray microtomography (XμT) and ...

CONE BEAM COMPUTED TOMOGRAPHY EVALUATION OF TWO OBTURATION TECHNIQUES AFTER PREPARATION WITH TWO NOVEL ROTARY SYSTEMS (IN VITRO STUDY) [PDF]

Alexandria Dental Journal, 2016
INTRODUCTION: Three dimensional obturation is an essential factor for the success of root canal treatment which is achieved by the adaptation of the root filling to the canal walls to create a homogenous mass of filling.OBJECTIVES: To compare the ...

Mitotic chromosomes are compacted laterally by KIF4 and condensin and axially by topoisomerase IIα [PDF]

Journal of Cell Biology, 2012
Mitotic chromosome formation involves a relatively minor condensation of the chromatin volume coupled with a dramatic reorganization into the characteristic “X” shape. Here we report results of a detailed morphological analysis, which revealed that chromokinesin KIF4 cooperated in a parallel pathway with condensin complexes to promote the lateral ...

Lateral and longitudinal compaction of PRC1 overlap zones drives stabilization of interzonal microtubules

Molecular Biology of the Cell, 2023
In mammalian cells, there is a gradual reduction in midzone microtubule dynamics from a single, highly dynamic population to a mixture of dynamic and more stable microtubules during anaphase. As cells enter telophase, the microtubules transition to a static array, which requires both lateral and longitudinal compaction of PRC1 on microtubules.

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.
