Comprehensive histopathological analysis of gastric cancer in European and Latin America populations reveals differences in PDL1, HER2, p53 and MUC6 expression.

Introduction: Gastric cancer (GC) burden is currently evolving with regional differences associated with complex behavioural, environmental, and genetic risk factors. The LEGACy study is a Horizon 2020-funded multi-institutional research project conducted prospectively to provide comprehensive data on the tumour biological characteristics of gastroesophageal cancer from European and LATAM countries.

Material And Methods: Treatment-naïve advanced gastroesophageal adenocarcinoma patients were prospectively recruited in seven European and LATAM countries.

Integrating molecular analyses with the 2021 WHO classification of adult pilocytic astrocytomas.

Pilocytic astrocytomas (PAs) are benign grade 1 gliomas according to the World Health Organization (WHO). They are common in children but rare in adults in whom they may have a worse prognosis. Pediatric PAs are usually associated with dysregulation of the mitogen-activated protein kinase (MAPK) pathway, often involving BRAF alterations such as the KIAA1549::BRAF (K-B) fusion or V600E mutation.

In vivo reduction of skin inflammation using ferulic acid-loaded lipid vesicles derived from Brewer's spent grain.

Breweŕs spent grain (BSG) is the main by-product of the brewing industry, and due to its rapid decomposition, it generates serious environmental problems such as malodors and greenhouse gases emissions. On the other hand, this lignocellulosic compound contains a large number of antioxidants, being ferulic acid (FA) the most abundant. FA is a powerful antioxidant molecule that has demonstrated significant protective effects on key components of the skin, including keratinocytes, fibroblasts, collagen, and elastin.

Isolation of β-O-4-Rich Lignin From Birch in High Yields Enabled by Continuous-Flow Supercritical Water Treatment.

The continuous flow supercritical water (scHO) treatment of Birch wood (T=372-382 °C; t=0.3-0.7 s; p=260 bar) followed by alkali extraction of lignin allowed for the isolation of lignin and lignin carbohydrate complexes (LCCs) with a high number of β-O-4 moieties in the range 29-57/100 Ar (evaluated by quantitative C NMR analysis) in yields ranging between 13-19 wt % with respect to the initial wood.

A comparative assessment of treatment methods to release ferulic and p-cumaric acids from Brewer's Spent Grains.

Brewers' spent grain (BSG) is the main byproduct from the brewing industry, which accounts for 85 % of the total waste generated during beer production. This lignocellulosic material is traditionally used as livestock feed and sold at a low price. However, BSG can be used as a low-cost feedstock for the production of bioactive molecules and chemicals precursors, upgrading the value of this byproduct.
