T-PEC: a novel test for the elicited production of clitic pronouns in Italian. Preliminary data.

The study presented in this article aims at investigating the clinical usefulness of a novel test, called T-PEC, for the diagnosis of Developmental Language Disorder in Italian preschool children. The instrument exploits the production of clitic pronouns, in particular third person direct object clitics (3PDO-CL), as a clinical marker for the disorder. Psychometric properties and normative data were computed on a sample of 70 children ranging in age from 4.

Functional differences in visceral and subcutaneous fat pads originate from differences in the adipose stem cell.

Metabolic pathologies mainly originate from adipose tissue (AT) dysfunctions. AT differences are associated with fat-depot anatomic distribution in subcutaneous (SAT) and visceral omental (VAT) pads. We address the question whether the functional differences between the two compartments may be present early in the adipose stem cell (ASC) instead of being restricted to the mature adipocytes.

Role of the PPAR-γ system in normal and tumoral pituitary corticotropic cells and adrenal cells.

PPAR-γ is a member of the nuclear hormone receptor superfamily of transcription factors, whose thiazolidinedione ligands (TZD) have been recently demonstrated to also possess anticancer properties in addition to their well-known insulin-sensitizer and glucose/lipid regulation activity. In this minireview, we summarize the current knowledge on PPAR-γ in normal and tumoral corticotropic pituitary and adrenal cells. The receptor expression has been shown in ACTH-secreting cells in both normal and adenomal pituitary as well as in normal and tumor adrenal cortex.

Peroxisome-proliferator-activated receptor gamma (PPARgamma) is required for modulating endothelial inflammatory response through a nongenomic mechanism.

Besides their well-known anti-diabetic effects, the peroxisome-proliferator-activated receptor gamma (PPARgamma) thiazolidinedione ligands (TZD) have been suggested to also display anti-inflammatory properties. The receptor role in mediating such effects is far from being elucidated. Here, we demonstrated that PPARgamma is necessary for TZD to interfere with TNFalpha and IFNgamma inflammatory activity in human endothelial cells.

Comparison between VDR analogs and current immunosuppressive drugs in relation to CXCL10 secretion by human renal tubular cells.

During kidney allograft rejection, CXC chemokine ligand 10 (CXCL10)-CXC chemokine receptor 3 (CXCR3) trafficking between peripheral blood and tissues initiates alloresponse and perpetuates a self-inflammatory loop; thus, CXCL10-CXCR3 axis could represent a pharmacologic target. In this perspective, immunosuppressors targeting graft-resident cells, beside immune cells, could be very advantageous. Vitamin D receptor (VDR) agonists exhibit considerable immunomodulatory properties.

Immunosuppression in cardiac graft rejection: a human in vitro model to study the potential use of new immunomodulatory drugs.

CXCL10-CXCR3 axis plays a pivotal role in cardiac allograft rejection, so that targeting CXCL10 without inducing generalized immunosuppression may be of therapeutic significance in allotransplantation. Since the role of resident cells in cardiac rejection is still unclear, we aimed to establish reliable human cardiomyocyte cultures to investigate Th1 cytokine-mediated response in allograft rejection. We used human fetal cardiomyocytes (Hfcm) isolated from fetal hearts, obtained after legal abortions.
