Calcium is the most abundant mineral in the human body and is involved in critical physiological and cellular processes. It is essential for the development, maintenance, and integrity of bone tissue throughout life. Identifying new natural food-grade chelating agents to improve calcium uptake is of increasing interest.

Research on new strategies to regulate glucose homeostasis to prevent or manage type 2 diabetes is a critical challenge. Several studies have shown that protein-rich diets could improve glucose homeostasis. Whey protein hydrolysis allows the release of amino acids and bioactive peptides, which exert numerous well-documented bioactivities.

Milk and dairy products are significant sources of proteins and peptides impacting human health. In this way, the interest in CPPs, bioactive phosphorylated peptides resulting from the hydrolysis of caseins, has grown in the past years. CPPs were mainly studied for their capacity to chelate and increase the bioavailability of essential minerals involved in multiple physiological processes.

The identification of phosphopeptides is currently a challenge when they are part of a complex matrix of peptides, such as a milk protein enzymatic hydrolysate. This challenge increases with both the number of phosphorylation sites on the phosphopeptides and their amino acid length. Here, this paper reports a four-phase strategy from an enzymatic casein hydrolysate before a mass spectrometry analysis in order to enhance the identification of phosphopeptides and phosphosites: (i) the control protein hydrolysate, (ii) a two-step enzymatic dephosphorylation of the latter, allowing for the almost total dephosphorylation of peptides, (iii) a one-step enzymatic dephosphorylation, allowing for the partial dephosphorylation of the peptides and (iv) an additional endoGluC enzymatic hydrolysis, allowing for the cleavage of long-size peptides into shorter ones.

Background: The aim of our study was to describe a large population with anomalies involving the SHOX region, responsible for idiopathic short stature and Léri-Weill dyschondrosteosis (LWD), and to identify a possible genotype/phenotype correlation.

Methods: We performed a retrospective multicenter study on French subjects with a SHOX region anomaly diagnosed by multiplex ligation-dependent probe amplification or Sanger sequencing. Phenotypes were collected in each of the 7 genetic laboratories practicing this technique for SHOX analysis.

Core Facilities are key elements in the research portfolio of academic and private research institutions. Administrators overseeing core facilities (core administrators) require assessment tools for evaluating the need and effectiveness of these facilities at their institutions. This article discusses ways to promote best practices in core facilities as well as ways to evaluate their performance across 8 of the following categories: general management, research and technical staff, financial management, customer base and satisfaction, resource management, communications, institutional impact, and strategic planning.

Background/aims: Transient idiopathic hyperglycaemia (TIH) is partly due to defective processing of proinsulin to insulin in preterm neonates, whereas transient neonatal diabetes mellitus (TNDM) is a rare genetic form of pancreatic β-cell dysfunction. Distinguishing these two conditions is difficult yet essential to allow personalised management and genetic testing. Here we investigated whether metabolic or therapeutic features contributed to the diagnosis in preterm neonates.

We report on a 3-year-old girl with a de novo complex X chromosome rearrangement associated with congenital pulmonary alveolar proteinosis (PAP) and short stature. Array comparative genome hybridization and FISH analyses contributed to characterize the complex rearrangement consisting of a 7.37 Mb terminal deletion of Xp22.

The relative importance of the cytokine milieu versus cytolytic T lymphocyte-associated antigen 4 (CTLA-4) and T cell receptor signal strength on T cell differentiation remains unclear. Here we have generated mice deficient for signal transducer and activator of transcription 6 (STAT6) and CTLA-4 to determine the role of CTLA-4 in cytokine-driven T cell differentiation. CTLA-4-deficient T cells bypass the need for STAT6 in the differentiation of T helper type 2 (T(H)2) cells.

Objective: Treatment of autoimmune diseases with therapies that tolerize pathogenic lymphocytes may obviate the need for longterm global immunosuppression. In vitro, non-Fc receptor binding derivatives of anti-murine CD3 monoclonal antibodies tolerize type 1 T cells and stimulate type 2 T cells. Recently, a humanized non-FcR binding derivative of the anti-human CD3 Mab OKT3, huOKT3gamma1(ala-ala), has been described.

Background: Type 1 diabetes mellitus is a chronic autoimmune disease caused by the pathogenic action of T lymphocytes on insulin-producing beta cells. Previous clinical studies have shown that continuous immune suppression temporarily slows the loss of insulin production. Preclinical studies suggested that a monoclonal antibody against CD3 could reverse hyperglycemia at presentation and induce tolerance to recurrent disease.
