Morphological and Functional Characterization of IL-12Rβ2 Chain on Intestinal Epithelial Cells: Implications for Local and Systemic Immunoregulation.

Interaction between intestinal epithelial cells (IECs) and the underlying immune systems is critical for maintaining intestinal immune homeostasis and mounting appropriate immune responses. We have previously showed that the T helper type 1 (T1) cytokine IL-12 plays a key role in the delicate immunological balance in the gut and the lack of appropriate levels of IL-12 had important consequences for health and disease, particularly with regard to food allergy. Here, we sought to understand the role of IL-12 in the regulation of lymphoepithelial cross talk and how this interaction affects immune responses locally and systemically.

Type 1 diabetes, sport practiced, and ankle joint mobility in young patients: What is the relationship?

Background/objective: It is known that patients with diabetes can develop limited joint mobility (LJM) and that this can depend on the metabolic control maintained and the duration of the disease. The aims of this study were to verify the presence of ankle joint mobility (AJM) deficits in both plantar and dorsiflexion in young type 1 diabetic patients (T1D) considering also the possible role of sport practiced as a further factor, able to modify AJM.

Methods: AJM was evaluated by an inclinometer in 82 T1D patients (M/F: 48/34), mean age 12.

History vs. legend: Retracing invasion and spread of Oxalis pes-caprae L. in Europe and the Mediterranean area.

Oxalis pes-caprae L. is a South African geophyte that behaves as an invasive in the eurimediterranean area. According to a long-established hypothesis, O.

Snow's case revisited: new tool in geographic profiling of epidemiology.

Geographic Profiling technique is used to find the origin of a series of crimes. The method was recently extended to other fields. One of the best renowned data in epidemiology is that by John Snow during an outburst of cholera in London.

Statistical detection of nanoparticles in cells by darkfield microscopy.

In the fields of nanomedicine, biophotonics and radiation therapy, nanoparticle (NP) detection in cell models often represents a fundamental step for many in vivo studies. One common question is whether NPs have or have not interacted with cells. In this context, we propose an imaging based technique to detect the presence of NPs in eukaryotic cells.

The psychological aspects in sexually transmitted infections.

Background: Over the last years the number of sexually transmitted diseases has greatly increased. This can be attributed mainly to less rigidity in the gender role and to the ever growing sexual liberalization. Sexuality today as in the past, represents an important and complex dimension of the human being.

Hepato-systemic gradient of carbon monoxide in cirrhosis.

Background And Aims: Experimental data suggest that in liver cirrhosis splanchnic and systemic vasculature exhibit marked endothelial Carbon monoxide (CO) overproduction, while recent data demonstrated heme oxygenase (HO) hyperactivity in the liver of rats with cirrhosis. No data are so far available on CO levels in the hepatic veins of cirrhotic patients. We aimed at evaluating whether plasma CO levels differ between systemic (peripheral vein) and hepatic (hepatic vein) circulation in patients with viral cirrhosis with and without ascites.

Increased plasma carbon monoxide in patients with viral cirrhosis and hyperdynamic circulation.

Objectives: Our aim was to measure plasma carbon monoxide (CO) in patients with liver cirrhosis and portal hypertension.

Methods: In 36 cirrhotic patients (24 with ascites) and 9 healthy volunteers, we evaluated CO plasma levels and systemic hemodynamics (using ultra-trace gas chromatography and echocardiography, respectively). Heme oxygenase (HO) activity and expression were measured in isolated polymorphonuclear (PMN) cells.
