Microscale Patterning of Ultrahigh‐Viscosity Metallic‐Polymer Composites via Embedded Droplet Writing

Advanced Functional Materials, EarlyView.
A hybrid additive manufacturing platform integrates direct droplet writing of metallic composite with VAT photopolymerization to fabricate architected soft magnetic composites. This approach enables microscale patterning of high‐viscosity materials for programmable actuators, adaptive fluidic devices, and switchable adhesives, offering tunable ...

Die Vaterfamilie: eine bislang weitgehend 'unentdeckte' Familienform

Journal of Family Research, 1998
In Deutschland standen Väter bisher nur selten im Mittelpunkt sozialwissenschaftlicher Forschung. Erst recht gilt dies für alleinerziehende Väter; obwohl die sogenannten Vaterfamilien die schnellst wachsende Familienform sind.

Radical Resection of the Third Portion of the Duodenum for Secondary Aortoduodenal Fistula. [PDF]

Ann Gastroenterol Surg
Secondary aortoduodenal fistula most commonly involves the third portion of the duodenum and requires definitive management of both vascular and gastrointestinal components. We demonstrate a step‐by‐step technique for radical duodenal resection and reconstruction performed in structured collaboration with cardiovascular surgeons.

Reimplantation of the papilla of Vater

Journal of British Surgery, 1985
Abstract Detachment of the papilla of Vater from the duodenum may happen (a) deliberately, during duodenal resection for tumour without concomitant resection of the pancreatic head, and (b) accidentally in the course of gastrectomy for duodenal ulcer, when attempts to exteriorize the ulcer are made.

Graded Metallopolymer Structures with Shape‐Memory Abilities via DLP‐Based 3D‐Printing

Advanced Functional Materials, EarlyView.
This study presents the digital light processing (DLP) based 3D printing of graded metallopolymers featuring shape‐memory abilities. The permanent shape can be recovered in two distinct steps with excellent rates. The obtained graded prints range from simple rod‐like structures to complex hollow materials.

Coexistent ampullary squamous cell carcinoma with adenocarcinoma of the pancreatic duct

The Saudi Journal of Gastroenterology, 2011
Primary squamous cell carcinoma (SCC) of ampulla has seldom been reported. However, metastatic SCC to ampulla of Vater is well known. We report a case of primary SCC of ampulla of Vater coexistent with well-differentiated adenocarcinoma of the distal ...

Post-Metachronous Cancer of the Ampulla of Vater after Gastric Cancer Surgery: An Overview

Journal of the Dow University of Health Sciences, 2022
Post-metachronous ampulla of Vater carcinoma after gastric cancer is an extremely rare between multiple primary cancers. The published literature contains only a few cases. Among the cases males are found more frequently.

Deciphering the Photopolymerization‐Induced Nanostructures and Interface Formation for Submicrometer Additive Manufacturing

Advanced Functional Materials, EarlyView.
This work reveals the UV‐curing‐induced monomer‐rich domain, oligomer‐rich domain, and entangled oligomer domain. The cured submicron films in stressed state induce interlayer nano‐wrinkle structures during the deposition of the second layer. Stress‐free cured films in relaxed state form non‐diffusive, diffusive and semi‐diffusive interlayer ...

Carcinoma adenoescamoso de la ampolla de Vater: una patología inusual y con pobre pronóstico

Anales de la Facultad de Medicina, 2014
El carcinoma adenoescamoso de la ampolla de Váter es una neoplasia rara (incidencia de 1% de todas las neoplasias de la ampolla de Váter), en la que los componentes glandular y escamoso son histológicamente malignos.

Advances in 3D Bioprinting for Breast Cancer Modeling: Tumor Microenvironment, Metastasis, and Drug Screening

Advanced Healthcare Materials, EarlyView.
Three‐dimensional bioprinting transforms breast cancer modeling from simple constructs into spatially organized, multicellular, perfused, and patient‐derived platforms. This review shows how bioinks, cellular composition, architecture, and flow govern tumor behavior and drug response, while revealing why complexity alone is insufficient without ...
