Multiple Myeloma Immunophenotype Related to Chromosomal Abnormalities Used in Risk Assessment.

(1) Background: At diagnosis, multiplemyeloma risk estimation includes disease burden, end-organ damage, and biomarkers, with increasing emphasis on genetic abnormalities. Multicolor flow cytometry (MFC) is not always considered in risk estimation. We demonstrate associations found between genetic abnormalities and antigen expression of plasma cells measured by MFC.

New associations of serum β-carotene, lycopene, and zeaxanthin concentrations with , , , AND genes.

Variation in carotenoid bioavailability at individual and population levels might depend on host-related factors where genetic variation has a part to play. It manifests itself through the proteins involved in carotenoid intestinal absorption and metabolism, blood lipoprotein transport, or tissue uptake. This study aims to identify novel SNPs which could be associated with carotenoid serum concentrations.

Oxidative Properties of Blood-Derived Extracellular Vesicles in 15 Patients After Myocardial Infarction.

BACKGROUND In this study, we investigated the yield and composition of extracellular vesicles (EVs) derived from 40- to 60-year-old healthy male controls and post-myocardial infarction (post-MI) patients' blood samples and assessed their pro-inflammatory and oxidative-related properties. Our study aimed to determine the EV yield and composition differences between both groups and to find out if there were differences between EV-mediated oxidative stress reactions. MATERIAL AND METHODS Fifteen post-MI patients and 25 healthy individuals were included.

Association between hair cortisol concentration and metabolic syndrome.

Metabolic syndrome (MetS) is a highly prevalent disorder defined as a cluster of cardiometabolic risk factors including obesity, hyperglycemia, hypertension, and dyslipidemia. It is believed that excessive cortisol secretion due to psychosocial stress-induced hypothalamic-pituitary-adrenal axis activation might be involved in the pathogenesis of MetS. We sought to explore the association between MetS and psychosocial risk factors, as well as cortisol concentration measured in different biological specimens including saliva, blood serum, and hair samples.
