Childhood obesity increases the risk of developing metabolic diseases in adulthood, since environmental stimuli during critical windows of development can impact on adult metabolic health. Studies demonstrating the effect of prepubertal diet on adult metabolic disease risk are still limited. We hypothesized that a prepubertal control diet (CD) protects the adult metabolic phenotype from diet-induced obesity (DIO), while a high-fat diet (HFD) would predispose to adult metabolic alterations.

Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is a rare inherited condition described worldwide and characterized by a wide spectrum of heterogeneity in terms of genotype and phenotype. How sacsin loss leads to neurodegeneration is still unclear, and current knowledge indicates that sacsin is involved in multiple functional mechanisms. We hence hypothesized the existence of epigenetic factors, in particular alterations in methylation patterns, that could contribute to ARSACS pathogenesis and explain the pleiotropic effects of SACS further than pathogenic mutations.

Purpose: A comprehensive analysis of metabolites (metabolomics) has been proposed as a new strategy for analyzing liquid biopsies and has been applied to identify biomarkers predicting clinical responses or adverse events associated with specific treatments. Here, we aimed to identify metabolites associated with bortezomib (Btz)-related toxicities and response to treatment in newly diagnosed multiple myeloma (MM).
Methods: Fifty-four plasma samples from transplant-ineligible MM patients enrolled in a randomized phase II study comparing two less-intensive regimens of melphalan, prednisolone and Btz (MPB) were subjected to the lipidomic profiling analysis.

-methyladenosine (mA) in eukaryotic RNA is an epigenetic modification that is critical for RNA metabolism, gene expression regulation, and the development of organisms. Aberrant expression of mA components appears in a variety of human diseases. RNA mA modification in has proven to be involved in sex determination regulated by and may affect X chromosome expression through the MSL complex.

In the current work, the MWCNTs/ZnO nanocomposite was successfully synthesized using simple method. Then, FE-SEM, XRD, and EDX techniques were applied for morphological and structural characterization. Afterward, a sensitive voltammetric sensor based on modification of a screen-printed carbon electrode (SPCE) using MWCNTs/ZnO nanocomposite was developed for the determination of doxorubicin in the presence of dacarbazine.
