Erythrocyte Membrane Fluidity and Omega-3 Fatty Acid Intake: Current Outlook and Perspectives for a Novel, Nutritionally Modifiable Cardiovascular Risk Factor.

Omega-3 fatty acids reduce triglycerides and have several positive effects on different organs and systems. They are also found in the plasma membrane in variable amounts in relation to genetics and diet. However, it is still unclear whether omega-3 supplementation can reduce the occurrence of major cardiovascular events (MACEs).

SGLT2 inhibition and adipose tissue metabolism: current outlook and perspectives.

Sodium-glucose co-transporter 2 inhibitors (SGLT2i) have emerged as important agents for the treatment of type 2 diabetes mellitus (T2DM). SGLT2 inhibitors have been associated with improved cardiovascular outcomes, not only through their immediate hemodynamic effects-such as glycosuria and (at least temporary) increased natriuresis-but also due to their multifaceted impact on metabolism. Recently, studies have also focused on the effects of SGLT2 inhibitors on adipose tissue.

Human subjects with impaired beta-cell function and glucose tolerance have higher levels of intra-islet intact GLP-1.

Aims: A number of studies have suggested that pancreatic α cells produce intact GLP-1, thereby constituting a gut-independent paracrine incretin system. However, the debate on whether human α cells contain intact GLP-1 and whether this relates to the presence of diabetes is still ongoing. This study aimed to determine the presence of proglucagon-derived peptides, including GLP-1 isoforms, in pancreas biopsies obtained during partial pancreatectomy from metabolically profiled human donors, stratified according to pre-surgery glucose tolerance.

A single bout of physical exercise improves 1-hour post-load plasma glucose in healthy young adults.

Purpose: Physical exercise is a key component in the treatment of type 2 diabetes and plays an important role in maintaining a healthy glucose metabolism even in healthy subjects. To date, no studies have investigated the effect of a single bout of aerobic physical exercise on glucose metabolism in young, moderately active, healthy adults.

Methods: We performed an OGTT 7 days before and 24 h after a single bout of physical exercise, to evaluate 1-hour post-load plasma glucose and surrogate indexes of insulin sensitivity and insulin secretion.

Advancing Diabetes Research: A Novel Islet Isolation Method from Living Donors.

Pancreatic islet isolation is critical for type 2 diabetes research. Although -omics approaches have shed light on islet molecular profiles, inconsistencies persist; on the other hand, functional studies are essential, but they require reliable and standardized isolation methods. Here, we propose a simplified protocol applied to very small-sized samples collected from partially pancreatectomized living donors.

Beta-cell function and glucose metabolism in patients with chronic pancreatitis.

Aims: Chronic pancreatitis (CP) is - along with acute pancreatitis - the most frequent cause of diabetes of the exocrine pancreas (DEP). Although insulin deficiency is widely accepted as the major feature of DEP, it is still unclear whether diabetes associated with CP is characterized by additional or different functional defects of the insulin secretory machinery. To identify possible functional defects specifically induced by CP, we performed a cross-sectional study in individuals with normal glucose tolerance (NGT), impaired glucose tolerance (IGT) and diabetes mellitus (DM) comparing patients with and without CP (CP vs.

Physical Activity and Type 2 Diabetes: In Search of a Personalized Approach to Improving β-Cell Function.

Type 2 diabetes mellitus (T2DM) is one of the most widespread diseases worldwide. Lifestyle interventions, including diet and physical activity (PA), are fundamental non-pharmacological components of T2DM therapy. Exercise interventions are strongly recommended for people with or at risk of developing or already with overt diabetes, but adherence to PA guidelines in this population is still challenging.

Identification and Molecular Characterization of a Novel Large-Scale Variant (Exons 4_18 Loss) in the LDLR Gene as a Cause of Familial Hypercholesterolaemia in an Italian Family.

Next-generation sequencing (NGS) is nowadays commonly used for clinical purposes, and represents an efficient approach for the molecular diagnosis of familial hypercholesterolemia (FH). Although the dominant form of the disease is mostly due to the low-density lipoprotein receptor (LDLR) small-scale pathogenic variants, the copy number variations (CNVs) represent the underlying molecular defects in approximately 10% of FH cases. Here, we reported a novel large deletion in the LDLR gene involving exons 4-18, identified by the bioinformatic analysis of NGS data in an Italian family.

An update on pancreatic regeneration mechanisms: Searching for paths to a cure for type 2 diabetes.

Background: Over the last decades, various approaches have been explored to restore sufficient β-cell mass in diabetic patients. Stem cells are certainly an attractive source of new β-cells, but an alternative option is to induce the endogenous regeneration of these cells.

Scope Of Review: Since the exocrine and endocrine pancreatic glands have a common origin and a continuous crosstalk unites the two, we believe that analyzing the mechanisms that induce pancreatic regeneration in different conditions could further advance our knowledge in the field.
