Gradient-grade solvents are suitable for liquid chromatography. These solvents are free from UV-absorbing impurities and ensure a consistent result in gradient analysis. Gradient grade solvents have undergone additional testing relative to isocratic solvents in order to ensure a low impurity gradient LC baseline and low gradient baseline drift.

Aspergillus fumigatus is a pathogenic fungus capable of causing both allergic lung disease and invasive aspergillosis, a serious, life-threatening condition in neutropenic patients. Aspergilli express an array of mycotoxins and enzymes which may facilitate fungal colonisation of host tissue. In

We have derived from normal human, mouse, and rat postnatal bone marrow primitive, multipotent adult progenitor cells (MAPCs) that can differentiate into most mesodermal cells and neuroectodermal cells in vitro and into all embryonic lineages in vivo. Here, we show

ATP analogs substituted in the gamma-phosphorus (ATPgammaS, beta, gamma-imido-ATP, and beta,gamma-methylene-ATP) were used to probe the involvement of P2 receptors in the modulation of synaptic transmission in the hippocampus, because their extracellular catabolism was virtually not detected in CA1 slices.

Early diagnosis and prevention is very important for lung cancer patients. Previous studies have emphasized that the level of coenzyme Q10 (CoQ10), present primarily in mitochondria, decreases with age and is low in patients with chronic diseases. Our goal was
