The evolutionary path of the epithelial sodium channel δ-subunit in Cetartiodactyla points to a role in sodium sensing.

The epithelial sodium channel (ENaC) plays a key role in osmoregulation in tetrapod vertebrates and is a candidate receptor for salt taste sensation. There are four ENaC subunits (α, β, γ, δ) which form αβγ- or δβγ ENaCs. While αβγ-ENaC is a 'maintenance protein' controlling sodium and potassium homeostasis, δβγ-ENaC might represent a 'stress protein' monitoring high sodium concentrations.

[ANMCO Position paper: From acute to chronic disease: the needs of complex cardiac patients].

Managing a patient suffering from a chronic disease requires a multidisciplinary team that can take care of them beyond the simple coordination of various specialties. In this context, a central role in the treatment of chronic heart disease is the continuity of care that should promote organic integration among different hospital departments, hospital and community. This position paper of the Italian Association of Hospital Cardiologists (ANMCO) aims at defining the general principles to inspire care for complex cardiac patients at different phases of the disease.

Anti-p53 and anti-heat shock proteins antibodies in patients with malignant or pre-malignant lesions of the oral cavity.

Background: Evaluation of circulating anti-p53 antibodies is an easy-to-perform, widely employed, procedure to assess the p53 status in cancer patients.

Materials And Methods: Levels of circulating anti-p53 antibodies in patients affected either by oral SCC or by pre- malignant oral lesions were assayed using a commercial ELISA kit. Autoantibody titers to Hsp60 and Hsp72 were determined by conventional ELISA.
