Salivary gland tumours in Iceland 1986-2015: a nationwide epidemiological analysis over a 30-year time period.

Salivary gland tumours (SGT) are a vast and heterogenous group of neoplasms. There is a relative lack of comprehensive nationwide epidemiological studies on the subject. The aim of this nationwide analysis was to gain insight into epidemiological traits, such as site, incidence and histological subtypes of SGT in general.

Placental protein 13 (PP13) stimulates rat uterine vessels after slow subcutaneous administration.

Introduction: Reduced concentrations of placental protein 13 (PP13) during the first trimester of human pregnancy are associated with elevated risk for the subsequent development of preeclampsia, which is one of the deadliest obstetrical complications of pregnancy. Previous studies by our group have shown that PP13 lowers blood pressure in pregnant rats, increases the size and weight of pups and placentas, and induces vasodilation of resistance arteries through endothelial signaling pathways involving endothelial nitric oxid synthase and prostaglandin.

Methods: In the present study, the effect of PP13 was investigated in nonpregnant female Sprague Dawley rats (n=27).

[Latent autoimmune diabetes in adults in Iceland: prevalence, phenotype and relatedness].

Introduction: Ninety percent of diabetic individuals in Iceland suffer from type 2 diabetes mellitus. Antibodies against ss-cell components characterise type 1 diabetes, but these antibodies are also found in type 2 diabetic individuals, defined as latent autoimmune diabetes in adults or LADA. The purpose of this investigation was to estimate the prevalence of LADA in Iceland and to describe the phenotype and relatedness of these individuals.
