Neurodegenerative disorders, such as Alzheimer's disease (AD), Parkinson's disease (PD) and frontotemporal dementias (FTD), are considered distinct entities, however, there is increasing evidence of an overlap from the clinical, pathological and genetic points of view. All neurodegenerative diseases are characterized by neuronal loss and death in specific(More)
The adenylate cyclase system present in particulate fractions prepared from two planarian species was tested for sensitivity to various neurotransmitters. While dopamine and other catecholamines were ineffective, serotonin was capable of stimulating the enzyme. Among the various serotonin agonists tested, only 8-OH-DPAT resulted effective on the adenylate(More)
The effect of nerve growth factor (NGF) on the utilization and fate of uniformly labeled 14C glucose and on the content of several pyridine and purine nucleotides has been tested in the clonal cell line PC12. After incubation for 72 h with NGF, PC12 cells exhibit a 2.7-fold increase in glucose utilization and a 4.7-fold increase in CO2 release. During the(More)
In recent years there has been a large scientific and public debate on climate change and its direct as well as indirect effects on human health. In particular, a large amount of research on the effects of climate changes on human health has addressed two fundamental questions. First, can historical data be of some help in revealing how short-run or(More)
The dystrobrevins (alpha and beta) are components of the dystrophin-associated protein complex (DPC), which links the cytoskeleton to the extracellular matrix and serves as a scaffold for signaling proteins. The precise functions of the beta-dystrobrevin isoform, which is expressed in nonmuscle tissues, have not yet been determined. To gain further insights(More)
The identification of the forces that drive oil stock prices is extremely important given the size of the Oil&Gas industry and its links with the energy sector and the environment. In the next decade oil companies will have to deal with international policies to contrast climate change. This issue is likely to affect companies' shareholder values. In this(More)
In mammals, the biological activity of the stem/progenitor compartment sustains production of mature gametes through spermatogenesis. Spermatogonial stem cells and their progeny belong to the class of undifferentiated spermatogonia, a germ cell population found on the basal membrane of the seminiferous tubules. A large body of evidence has demonstrated that(More)
MicroRNAs (miRNAs) are emerging as key regulators of complex biological processes in several cardiovascular diseases, including atrial fibrillation (AF). Reverse transcription-quantitative polymerase chain reaction is a powerful technique to quantitatively assess miRNA expression profile, but reliable results depend on proper data normalization by suitable(More)
Cyclin-dependent kinase 5 regulatory subunit 1 (CDK5R1) encodes p35, the main activatory subunit of cyclin-dependent kinase 5 (CDK5). The p35/CDK5 active complex plays a fundamental role in brain development and functioning, but its deregulated activity has also been implicated in various neurodegenerative disorders, including Alzheimer’s disease (AD).(More)
Progranulin (PGRN) is a secreted protein expressed ubiquitously throughout the body, including the brain, where it localizes in neurons and is activated microglia. Loss-of-function mutations in the GRN gene are an important cause of familial frontotemporal lobar degeneration (FTLD). PGRN has a neurotrophic and anti-inflammatory activity, and it is(More)
