Cholesteryl ester storage disease (CESD) results from loss-of-function mutations in LIPA, the gene that encodes lysosomal acid lipase (LAL). Hepatomegaly and deposition of esterified cholesterol (EC) in multiple organs ensue. The present studies quantitated rates of synthesis, absorption, and disposition of cholesterol, and whole body cholesterol pool size in a mouse model of CESD. In 50-day-ol...

Degradation of lysosomal lipids requires lysosomal acid lipase (LAL), the only intracellular lipase known to be active at acidic pH. We found LAL to be expressed in murine immune cells with highest mRNA expression in macrophages and neutrophils. Furthermore, we observed that loss of LAL in mice caused lipid accumulation in white blood cells in the peripheral circulation, which increased in resp...

The lateral accessory lobe (LAL) mediates signals from the central complex to the thoracic motor centers. The results obtained from different insects suggest that the LAL is highly relevant to the locomotion. Perhaps due to its deep location and lack of clear anatomical boundaries, few studies have focused on this brain region. Systematic data of LAL interneurons are available in the silkmoth. ...

OBJECTIVE Genome-wide association studies have linked variants at chromosome 10q23 with increased coronary artery disease risk. The disease-associated variants fall in LIPA, which encodes lysosomal acid lipase (LAL), the enzyme responsible for lysosomal cholesteryl ester hydrolysis. Loss-of-function mutations in LIPA result in accelerated atherosclerosis. Surprisingly, the coronary artery disea...

The clinical outcome of 21 adults with ALL1(MLL)/AF4 positive acute lymphoblastic leukemia enrolled in the GIMEMA LAL 2000 trial and of 25 patients entered into the previous 0496 study is reported. LAL 2000 included more intensive consolidation and transplants. Complete remission rates were 90% and 88% in the LAL 2000 and 0496 trials, respectively. Fifteen patients were transplanted (5 autologo...

The use of unmanned aerial vehicles (UAVs) to perform disaster relief task is becoming more and popular. Generally, UAVs for rescuing are required be heterogeneous, since the types rescue missions diverse. There many researches on allocation heterogeneous UAVs, in which they setup tasks randomly distributed when simulation. However, most cases distribution regular rather than random. Therefore,...

Lysosomal acid lipase deficiency (LAL-D) is a rare disorder of cholesterol metabolism with an autosomal recessive mode of inheritance. The absence or deficiency of the LAL enzyme gives rise to pathological accumulation of cholesterol esters in various tissues. A severe LAL-D phenotype manifesting in infancy is associated with adrenal calcification and liver and gastrointestinal involvement with...
