Follicular Helper T-cell Lymphoma With Hodgkin/Reed-Sternberg-Like Cells Versus Classic Hodgkin Lymphoma: A Comparative Study.

Lymphomas of T-follicular helper origin (T-follicular helper-cell lymphoma [TFHL]) are often accompanied by an expansion of B-immunoblasts, occasionally with Hodgkin/Reed-Sternberg-like (HRS-like) cells, making the differential diagnosis with classic Hodgkin lymphoma (CHL) difficult. We compared the morphologic, immunophenotypic, and molecular features of 15 TFHL and 12 CHL samples and discussed 4 challenging cases of uncertain diagnosis. Compared with CHL, TFHL disclosed more frequent sparing of subcortical sinuses, high-endothelium venule proliferation, dendritic cell meshwork expansion, T-cell atypia, and aberrant T-cell immunophenotype.

Silymarin-Enriched Extract from Milk Thistle Activates Thermogenesis in a Preclinical Model of High-Fat-Diet-Induced Obesity to Relieve Systemic Meta-Inflammation.

Background: Obesity and aging are associated with the progressive loss of brown adipose tissue (BAT), an increase in visceral white adipose tissue (vWAT), and a reduction in subcutaneous white adipose tissue (sWAT). The progressive expansion of visceral obesity promotes a low grade of systemic chronic inflammation (meta-inflammation), contributing to the onset of comorbidities such as type 2 diabetes mellitus (T2DM), metabolic syndrome, and even cancer. Thus, preserving the thermogenic activity of adipose tissue and improving the metabolic flexibility of sWAT could be an effective strategy to prevent the development of metabolic chronic diseases and promote healthy aging.

Bioavailability of Supplemented Free Oleanolic Acid and Cyclodextrin-Oleanolic Acid in Growing Pigs, and Effects on Growth Performance, Nutrient Digestibility and Plasma Metabolites.

Oleanolic acid (OLA) has beneficial health effects in animals, but in vivo efficacy in monogastric animals is questioned due to its low bioavailability. To gain further insight on the nutritional effects of OLA it was administered as part of a diet. We investigated digestibility and plasma OLA in pigs and the associated influence on growth, organs, digestibility of nutrients and plasma biochemical profile.

Polyphenols and Triterpenes Combination in an In Vitro Model of Cardiac Damage: Protective Effects.

Olive products contain high levels of monounsaturated fatty acids as well as other minor components such as triterpenic alcohols and other pentacyclic triterpenes, which together form the main triterpenes of virgin olive oil. Olive fruits and leaves contain significant amounts of hydrophilic and lipophilic bioactives including flavones, phenolic acids and phenolic alcohols, amongst others. Several studies have shown the benefits of these substances on the cardiovascular system.

Olive juice dry extract containing hydroxytyrosol, as a nontoxic and safe substance: Results from pre-clinical studies and review of toxicological studies.

Products derived from olives, such as the raw fruit and oils, are widely consumed due to their taste, and purported nutritional/health benefits. Phenolic compounds, especially hydroxytyrosol (HT), have been proposed as one of the key substances involved in these effects. An olive juice extract, standardized to contain 20% HT ("OE20HT"), was produced to investigate its health benefits.
