The vacuolar H(+)-translocating ATPase (H(+)-ATPase), originally reported to consist of three major subunits, has been further purified from oat roots (Avena sativa var Lang) to determine the complete subunit composition. Triton-solubilized ATPase activity was purified by gel filtration on Sephacryl S400 and ion-exchange chromatography (Q-Sepharose). ATP hydrolysis activity of purified preparat...

PRIMARY nonfunction (PNF) of the liver is an inexact term and investigators continue to debate the site and origin of preservation injury. Some grafts with PNF fail in the operating room. while other grafts have to be replaced between I and 14 days postoperatively. The pathology of such grafts displays a spectrum of findings ranging from marked hepatocellular swelling and cholestasis to massive...

Colorectal cancer is one of the most frequently diagnosed malignancies in women and men. All systemic treatment options for colorectal cancer are based on 5-fluorouracil (5-FU), often administered in combination with oxaliplatin or irinotecan. Resistance to chemotherapy is a major obstacle to successful therapy. Nuclear factor kappa light chain enhancer of activated B cells (NF-κB) is a collect...

The purpose of this study was to determine if a particularsomatic cell count (SCC) range can be used as an indicator ofintramammary infection (IMI). Mastitis in dairy cows is mostlycaused by microbial infections and changes in pathogenicitymay be indicated by increased SCC. Cyto-microbiologicalexaminations were performed on 491 464 quarter andcomposite cow milk sampl...

Images of a scene captured with multiple cameras have different color values due to variations in capture and color rendering across devices. We present a method to accurately retrieve color information from uncalibrated images taken under uncontrolled lighting conditions with an unknown device and no access to raw data, but with a limited number of reference colors in the scene. The method is ...

K. McMahon, A. Pringle, M. Eastburn, D. Maillet Centre for Magnetic Resonance, University of Queensland, Brisbane, Queensland, Australia Introduction: Echo planar imaging (EPI) is a rapid sequence that has been applied with great success to diffusion, perfusion and functional magnetic resonance imaging (fMRI) of the brain. However, the oscillating gradients in EPI can produce artefacts such as ...

nutrient in estuaries. Phosphorus enters surface waters in both dissolved and particulate form and is generally Much of the nonpoint N and P entering surface waters of the the limiting nutrient in lakes. A large portion of the N Midwest is from agriculture. We determined if constructed wedands could be used to reduce nonpoint N and P exports from agricultural and P now entering U.S. freshwater ...

Auf der ACHEMA 2022 waren in Frankfurt 38 Anbieter von Zerkleinerungstechnik vertreten. Der vorliegende Bericht fasst kurz zusammen, welche Aussteller vertreten und was – vor allem an Neuerungen gezeigt wurde. Schwerpunkte einerseits Maschinen zum Dispergieren verklumpter bzw. sehr feinkörniger Pulver zur besseren Verarbeitbarkeit oder Einmischen Flüssigkeiten sowie andererseits Mahlkörpermühle...
