Abstract Background The relative ease of targeted gene disruption in the social amoeba Dictyostelium has stimulated its widespread use as an experimental organism for cell and developmental biology.However, the field has been hamstrung by the lack of techniques to recombine disrupted genes.Results We describe new techniques for parasexual fusion of
Control of Membrane Fouling in Organics Filtration Using Ce-Doped Zirconia and Visible Light
Membrane fouling has been a major issue in the development of more efficient water treatment processes.Specifically in surface waters filtration, organic matter, such as humic-like substances, can cause irreversible fouling.Therefore, this study evaluates the activity of a photocatalytic layer composed of Ce-doped zirconia nanoparticles in improvin
Hyperleptinemia is required for the development of leptin resistance.
Leptin regulates body weight by signaling to the brain the availability COARSE GREY SEA SALT of energy stored as fat.This negative feedback loop becomes disrupted in most obese individuals, resulting in a state known as leptin resistance.The physiological causes of leptin resistance remain poorly understood.Here we test the hypothesis that hyperlep
Ammonia and ammonium over the southern Baltic Sea. Part 1. Preparation of aerosol and air samples for the determination of ammonia by the indophenol method
1997 saw the start of a study into the spatial and temporal changes in the chemical composition of the atmosphere over the littoral and offshore waters of the Baltic Sea.Collection Blenders of samples and their subsequent chemical analysis was preceded by meticulous laboratory experiments concerning the validation and adaptation of the analytical p
