Suboptimal concordance in testing and retesting results of triple-negative breast carcinoma cases among laboratories: one institution experience

open access: yesCancer Cell International, 2019
Background Triple-negative breast carcinoma (TNBC) patients do not benefit from hormone- or human epidermal growth factor receptor 2- (HER2-) targeted therapies. Accurate testing is pivotal for these patients. Methods TNBC cases that were retested at our

Growth of GaN blue LEDs with in situ growth monitoring

open access: yesIII-Vs Review, 1997
AbstractOne of the most exciting developments in the field of III–V semiconductors in the last several years has been the application of the AI-Ga-In Nitride material system to the production of UV-to-green light emitting devices. From the pioneering research of Akasaki and Nakamura to the production of LEDs by such companies as Nichia, CREE and Toyoda

In-situ growth studies of sputtered ybco thin films by spectroscopic ellipsometry [PDF]

open access: yes, 1997
Using spectroscopic ellipsometry we studied in-situ the growth of off-axis sputtered YBa2Cu3O6+x thin films on (001) SrTiO3 as a function of the deposition parameters. Especially in the very first growth stage (106A cm¿2 @ 77 K) is smooth and homogeneous,

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

In situ stable crack growth at the micron scale [PDF]

open access: yesNature Communications, 2017
AbstractGrain boundaries typically dominate fracture toughness, strength and slow crack growth in ceramics. To improve these properties through mechanistically informed grain boundary engineering, precise measurement of the mechanical properties of individual boundaries is essential, although it is rarely achieved due to the complexity of the task ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

In situ growth of CuO nanoparticles onto cotton textiles

open access: yesAdvances in Natural Sciences: Nanoscience and Nanotechnology, 2020
The application of nanotechnology has gained importance in the finishing of textile products, imparting them functional properties, which are achieved without affecting the textile. A novel method was developed for the in situ growth of CuO nanoparticles

In situ study of the endotaxial growth of hexagonal CoSi2 nanoplatelets in Si(001) [PDF]

open access: yes, 2015
This investigation aims at studying-by in situ grazing-incidence small-angle x-ray scattering-the process of growth of hexagonal CoSi2 nanoplatelets endotaxially buried in a Si(001) wafer.

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...
