The Early Upper Palaeolithic open‐air site of Friedrichsdorf‐Seulberg, Germany, in the context of the northern central European Aurignacian

Boreas, EarlyView.
Our knowledge of the Early Upper Palaeolithic occupation in northern central Europe is very limited, and recent research at the open‐air site of Friedrichsdorf‐Seulberg in Hesse, Germany, provides important new information on the Aurignacian. The site is rather small (26.5 m2) and spatial analysis identified a central hearth with two associated ...

A bifacial paradise—The site of Ochtmissen, Germany, and its lithic assemblage in the context of the last glacial (early MIS 4) in the north‐central European Lowland

Boreas, EarlyView.
The Palaeolithic site of Ochtmissen (Lower Saxony, Germany) was excavated in fluvial terrace deposits during the winter of 1993/1994. The current study presents, for the first time, a thorough analysis of the lithic assemblage, encompassing its primary technological and typological characteristics, as well as the type and age of the fluvial deposits ...

Brain metastasis‐associated fibroblasts shape the tumour microenvironment to enhance cancer cell invasion

Brain Pathology, EarlyView.
Brain metastasis‐associated fibroblasts are active stromal components of the metastatic niche characterised by extracellular matrix remodelling and production of pro‐migratory mediators. They promote monocyte and cancer cell migration and enhance cancer cell invasion while having no growth‐promoting effect on cancer cells.

A revised classification system of the marronoid clade of spiders (Araneae), based on dense sampling phylogenomics and comparative morphology

Cladistics, EarlyView.
Abstract The marronoid clade is a globally distributed, ecologically diverse group of spiders. It is an important faunal component in both natural and synanthropic environments, and even found in aquatic and extreme habitats such as desert salt flats. The systematics of the marronoid clade has been notoriously unstable due to the widespread character ...

Effect of Hyaluronic Acid on Palatal Wound Healing—A Randomized Crossover Clinical Trial

Clinical Oral Implants Research, EarlyView.
ABSTRACT Aim To assess the effect of a hyaluronic acid (HyA) containing gel on patient‐related outcomes (PRO) and wound healing after palatal punch‐biopsy representing a free gingival graft. Material and Methods A punch‐biopsy (6 mm diameter, 2 mm thickness) was harvested from one side of the palate at Day 0 and from the contralateral side at Day 21 ...

Adhesion of Newly Developed Composite Resin Splinting Materials to Enamel: Effect of Enamel Surface Treatment

Dental Traumatology, EarlyView.
ABSTRACT Background/Aim To evaluate the shear bond strength (SBS) of newly developed composite resin materials intended for dental splinting to enamel and to determine whether phosphoric acid etching alone provides reliable adhesion. Material and Methods Four experimental materials (G‐Fix, Light Fix, Ortho Connect, and Ortho Connect Flow) were compared

Effects of organic solvents on the depth‐of‐cure determination of conventional and bulk‐fill resin composites

European Journal of Oral Sciences, EarlyView.
Abstract This study investigated the influence of organic solvents on the depth of cure (DOC) of resin composites. Two conventional (Filtek Universal [FU] and Beautifil II [BE]) and two bulk‐fill (Filtek One Bulk Fill [FO] and Beautifil‐Bulk [BB]) composites were evaluated.
