“We examined the structure of personal life values as a representation of underlying motivation, in a Spanish sample of children and adolescents 12 – 16 years old. In general, results showed selleck screening library that youth put higher priority on intrinsic life goals (meaningful relationships, being physically healthy, self-acceptance) than extrinsic life goals (image, money, power). Gender differences were found in specific life goals. When comparing our results with another longitudinal American study using the same instrument and methodology,

we found similar results, although Spanish youth value priorities goals related to support rather than striving as m American adolescents. Cultural and age trend in life priorities are discussed.”
“Parkinson Disease (PD) is a common neurodegenerative disorder of intricate etiology, caused by progressive loss of aminergic neurons and accumulation of Lewy bodies. The predominant role of genetics in the etiology of the disease has emerged since the identification of the first pathogenetic mutation in SNCA (alpha-synuclein) gene, back in 1997. Mendelian parkinsonisms, a minority among all PD forms, have been deeply investigated, with 19 loci identified. More recently, genome wide association Nutlin-3 supplier studies have provided convincing evidence that variants in some of these genes, as well as in other genes, may confer an increased risk learn more for late onset, sporadic PD. Moreover, the finding that heterozygous mutations in the GBA gene (mutated in Gaucher disease) are among the strongest genetic susceptibility factors for PD, has widened the scenario of PD genetic background to enclose a number of genes previously associated to distinct

disorders, such as genes causative of spinocerebellar ataxias, mitochondrial disorders and fragile X syndrome. At present, the genetic basis of PD defines a continuum from purely mendelian forms (such as those caused by autosomal recessive genes) to multifactorial inheritance, resulting from the variable interplay of many distinct genetic variants and environmental factors.”
“A Ca2+ signaling model is proposed to consider the crosstalk of Ca2+ ions between endoplasmic reticulum (ER) and mitochondria within microdomains around inositol 1, 4, 5-trisphosphate receptors (IP3R) and the mitochondrial Ca2+ uniporter (MCU). Our model predicts that there is a critical IP3R-MCU distance at which 50% of the ER-released Ca2+ is taken up by mitochondria and that mitochondria modulate Ca2+ signals differently when outside of this critical distance. This study highlights the importance of the IP3R-MCU distance on Ca2+ signaling dynamics.
