Total Cranial Vault Remodelling Versus Minimally Invasive Suturectomy With Postoperative Helmet Therapy in Sagittal Craniosynostosis.

Different surgical techniques have been explored over time to treat children with scaphocephaly. The objective of this study is to compare morbidity and cosmetic outcomes in total cranial vault remodelling (TCVR) and minimally invasive suturectomy with postoperative helmet therapy (MISPH) in patients with scaphocephaly. The authors performed a retrospective comparative cohort study, including 43 patients with isolated sagittal craniosynostosis who underwent TCVR (n=17) or MISPH (n=26) at the Antwerp University Hospital between April 2008 and December 2022.

Monolithic Integration of Nano-Ridge Engineered InGaP/GaAs HBTs on 300 mm Si Substrate.

Nano-ridge engineering (NRE) is a novel method to monolithically integrate III-V devices on a 300 mm Si platform. In this work, NRE is applied to InGaP/GaAs heterojunction bipolar transistors (HBTs), enabling hybrid III-V/CMOS technology for RF applications. The NRE HBT stacks were grown by metal-organic vapor-phase epitaxy on 300 mm Si (001) wafers with a double trench-patterned oxide template, in an industrial deposition chamber.

Paroxysmal otalgia treated with microvascular decompression of the intermediate nerve: illustrative case.

Background: Intermediate nerve neuralgia is a rare type of cranial neuralgia that causes clinical, therapeutic, and diagnostic challenges. Studies have described pharmacological and surgical treatment options. Surgical treatment ranges from sectioning of neural structures to microvascular decompression.

Regulation of intestinal permeability: The role of proteases.

The gastrointestinal barrier is - with approximately 400 m - the human body's largest surface separating the external environment from the internal milieu. This barrier serves a dual function: permitting the absorption of nutrients, water and electrolytes on the one hand, while limiting host contact with noxious luminal antigens on the other hand. To maintain this selective barrier, junction protein complexes seal the intercellular space between adjacent epithelial cells and regulate the paracellular transport.

Observation and understanding of anisotropic strain relaxation in selectively grown SiGe fin structures.

The performance of heterogeneous 3D transistor structures critically depends on the composition and strain state of the buffer, channel and source/drain regions. In this paper we used an in-line high resolution x-ray diffraction (HRXRD) tool to study in detail the composition and strain in selectively grown SiGe/Ge fin structures with widths down to 20 nm. For this purpose we arranged fins of identical dimensions into larger arrays which were then analyzed using an x-ray beam several tens of micrometers in size.
