Reconstruction of Small Nasal Defects

open access: yesSeminars in Plastic Surgery
AbstractThe nose maintains a central importance in both functional and aesthetic human anatomy. With such importance comes numerous possible defects with equally plentiful techniques available for repair. One of the most common causes for nasal reconstruction is Mohs micrographic surgery to excise basal and squamous cell carcinomas.

Defect-Assisted Contact Property Enhancement in a Molybdenum Disulfide Monolayer

open access: yes, 2019
Contact engineering for two-dimensional (2D) transition metal dichalcogenides (TMDCs) is crucial for realizing high-performance 2D TMDC devices, and most studies on contact properties of 2D TMDCs have mainly focused on Fermi level unpinning.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

RCC prolapse causing Aortic regurgitation in a restrictive VSD [PDF]

open access: yes, 2015
The incidence of aortic right coronary cusp (RCC) prolapse in outlet ventricular septal defect (VSD) is reported at 5%- 16%. Detection of RCC prolapse is critical in patients with outlet VSD because this complication may cause permanent aortic ...
