Mechanical-scan-free multicolor super-resolution imaging with diffractive spot array illumination

Nature Communications
Point-scanning microscopy approaches are transforming super-resolution imaging. Despite achieving parallel high-speed imaging using multifocal techniques, efficient multicolor imaging methods with high-quality illumination are currently lacking.

A comparative fellow-eye prospective study evaluating the efficacy of wavefront-guided VSS VISX CustomVue STAR S4 IR versus the wavefront-optimized WaveLight Allegretto in correction of compound myopic astigmatism

Journal of the Egyptian Ophthalmological Society, 2015
Aim The aim of the present study was to compare the differences in visual outcomes, higher-order aberrations and corneal asphericity, as measured by Q values, in patients undergoing laser in-situ keratomileusis using wavefront-guided variable-spot size ...

A scanning electron microscope study of oxolinic acid treatment of burn spot lesions of Macrobrachium rosenbergii

, 1986
Black burn spot exoskeletal lesions of bacterial aetiology are a frequent feature of crustaceans in intensive culture. The appearance under the scanning electron microscope of such lesions associated with Aeromonas hydrophila on Macrobrachium rosenbergii

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Unraveling the Mechanism of Cork Spot-like Physiological Disorders in ‘Kurenainoyume’ Apples Based on Occurrence Location

Plants
Cork spot-like physiological disorder (CSPD) is a newly identified issue in ‘Kurenainoyume’ apples, yet its mechanism remains unclear. To investigate CSPD, we conducted morphological observations on ‘Kurenainoyume’ apples with and without pre-harvest ...

Segmented Gamma Scanning of Conditioned Radioactive Wastes:Development, Experimental Validation and Application of an Angular-Scanning Procedure for Hot-Spot Characterization

, 2003
The “angular scanning” method allows both localization of hot spot(s) and the evaluation of the corresponding activity. Taking into account the experimental setup parameters (e.g., drum geometry, drum-detector distance, collimator geometry, etc.), the ...

A new flow chip in combination with multiphoton microscopy as a protocol for longitudinal 3D imaging of tissue calcification under shear stress

FEBS Open Bio, EarlyView.
Miniaturized flow chip platform enabling continuous perfusion and longitudinal multiphoton 3D imaging of vascular smooth muscle cell constructs under physiological flow. Brightfield imaging guides region selection, while CellTracker Green and mRuby‐labeled fetuin‐A visualize cells and mineral deposition, respectively. Magnesium supplementation markedly

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

FEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...
