Inhibition of 7α,26-dihydroxycholesterol biosynthesis promotes midbrain dopaminergic neuron development.

Dysregulated cholesterol metabolism has been linked to neurodegeneration. We previously found that free, non-esterified, 7α,(25)26-dihydroxycholesterol (7α,26-diHC), was significantly elevated in the cerebrospinal fluid of patients with Parkinson's disease (PD). In this study we investigated the role of 7α,26-diHC in midbrain dopamine (mDA) neuron development and survival.

A Greek physician's portrait in Windsor Castle.

To the visitor to Windsor Castle, the Thomas Lawrence portraits in the Waterloo Chamber represent the most important contributors to the military defeat of Napoleon Bonaparte, by British, Prussian, Russian and Austrian forces at the Battle of Waterloo. Nevertheless, only few individuals realise that a Greek physician, Count Ioannis Capodistrias, a native of the island of Corfu, stands among these leading personalities as a diplomat, the Russian Minister of Foreign Affairs, who contributed remarkably to European unity in the early nineteenth century and as a statesman ('Governor' of Greece) with a tragic end to his life, after establishing a Greek State practically from ruins.

Virus antibody survey in different European populations indicates risk association between coxsackievirus B1 and type 1 diabetes.

Enteroviruses (EVs) have been connected to type 1 diabetes in various studies. The current study evaluates the association between specific EV subtypes and type 1 diabetes by measuring type-specific antibodies against the group B coxsackieviruses (CVBs), which have been linked to diabetes in previous surveys. Altogether, 249 children with newly diagnosed type 1 diabetes and 249 control children matched according to sampling time, sex, age, and country were recruited in Finland, Sweden, England, France, and Greece between 2001 and 2005 (mean age 9 years; 55% male).

Ιnflammatory or septic arthritis associated with mycoplasma pneumonia in children: Two case reports and review of the literature.

Inflammatory or septic arthritis due to Mp is an extremely unusual manifestation in children, and the functional outcome of the joints is difficult to be predicted. Two cases with Mp infection are presented. The first patient had positive PCR for Mp after hip aspiration and arthrotomy with thorough irrigation and debridement.
