BACKGROUND Parkinson's disease (PD) is an adult-onset movement disorder of largely unknown etiology. We have previously shown that loss-of-function mutations of the mitochondrial protein kinase PINK1 (PTEN induced putative kinase 1) cause the recessive PARK6 variant of PD. METHODOLOGY/PRINCIPAL FINDINGS Now we generated a PINK1 deficient mouse and… (More)
Proteasomal dysfunction and apoptosis are major hallmarks in the pathophysiology of Parkinson's disease (PD). PARK6 which is caused by mutations in the mitochondrial protein kinase PINK1 is a rare autosomal-recessively inherited disorder mimicking the clinical picture of PD. To investigate the cytoprotective physiological function of PINK1, we used primary… (More)
Saccular intracranial aneurysms are balloon-like dilations of the intracranial arterial wall; their hemorrhage commonly results in severe neurologic impairment and death. We report a second genome-wide association study with discovery and replication cohorts from Europe and Japan comprising 5,891 cases and 14,181 controls with approximately 832,000… (More)
Parkinson's disease (PD) is a neurodegenerative movement disorder of advanced age with largely unknown etiology, but well documented tissue damage from oxidative stress. Increased alpha-synuclein (SNCA) expression is known to cause a rare form of PD, early-onset autosomal dominant PARK4. We have previously shown that loss-of-function mutations of the… (More)
Mammalian cardiomyocytes become post-mitotic shortly after birth. Understanding how this occurs is highly relevant to cardiac regenerative therapy. Yet, how cardiomyocytes achieve and maintain a post-mitotic state is unknown. Here, we show that cardiomyocyte centrosome integrity is lost shortly after birth. This is coupled with relocalization of various… (More)
The eukaryotic glyoxalase system consists of two enzymatic components, glyoxalase I (lactoylglutathione lyase) and glyoxalase II (hydroxyacylglutathione hydrolase). These enzymes are dedicated to the removal of toxic α-oxoaldehydes like methylglyoxal (MG). MG is formed as a by-product of glycolysis and MG toxicity results from its damaging capability… (More)
This paper describes a Low-Noise Amplifier (LNA), designed using a 0.25-µm SiGe process, operating in the 4.4– 5 GHz band. A power gain of 12.8 dB at 5 GHz has been achieved with a power consumption of 23.77 mW using a 2 V power supply. The noise figure is 2.2 dB while the input referred 1dB compression point is −6.2 dBm.
Choline uptake into cholinergic neurons for acetylcholine (ACh) synthesis is by a specific, high-affinity, sodium- and temperature-dependent transport mechanism (HAChU). To assess the role of choline availability in regulation of ACh synthesis, the structure-activity relationships of several hemicholinium (HC) and quinuclidinyl analogs were evaluated in a… (More)
Skeletal muscles provide metazoans with the ability to feed, reproduce and avoid predators. In humans, a heterogeneous group of genetic diseases, termed muscular dystrophies (MD), lead to skeletal muscle dysfunction. Mutations in the gene encoding Caveolin-3, a principal component of the membrane micro-domains known as caveolae, cause defects in muscle… (More)
In this work a new test structure for mismatch characterization of CMOS technologies is presented. The test structure is modular, with a reduced area and it can be inserted in the space between the dies (scribe lines) on the wafers. The test structure has been implemented in a standard 0.18-µm digital CMOS technology.
