Photosynthetic diatoms are exposed to rapid and unpredictable changes in irradiance and spectral quality, and must be able to acclimate their light harvesting systems to varying light conditions. Molecular mechanisms behind light acclimation in diatoms are largely unknown. We set out to investigate the mechanisms of high light acclimation in Phaeodactylum tricornutum using an integrated approac...

Rainbow smelt (Osmerus mordax) display an impressive ability to acclimate to very cold water temperatures. These fish express both anti-freeze proteins and glycerol in their plasma, liver, muscle and other tissues to avoid freezing at sub-zero temperatures. Maintenance of glycerol levels requires active feeding in very cold water. To understand how these fish can maintain activity at cold tempe...

We aimed at testing potential effects of extraocular bright light via the ear canals on human evening melatonin levels, sleepiness and psychomotor vigilance performance. Twenty healthy young men and women (10/10) kept a regular sleep-wake cycle during the 2-week study. The volunteers reported to the laboratory on three evenings, 2 h 15 min before usual bedtime, on average at 21:45 h. They were ...

A method for the study of the control of the attainment of thermal acclimation has been applied to the crabs, Cancer pagurus and Carcinus maenas. Crabs were heterothermally acclimated by using an anterior-posterior partition between two compartments, one at 8 degrees C and the other at 22 degrees C. One compartment held a three-quarter section of the crab including the central nervous system (C...

Sorption-based techniques have been widely studied for metal recovery. Conventionally, sorption and desorption steps are operated in fixed-bed column system under one-pass mode (FO); however, such requires a large volume of solution passing the bed when feed concentration is low. In this study, highly stable amine-coated alginate melamine (ML/APG) sponge was prepared applied combined process in...

Single fibres were isolated from the fast myotomal muscle of the short-horned sculpin (Myoxocephalus scorpius L.). Fish were acclimated to either 5 °C (10 h:14 h light:dark) or 15 °C (12 h:12 h light:dark) for 1­2 months. Isometric tension (Fmax) and unloaded contraction velocity (Vslack) were determined in maximally activated skinned fibres over the range 0 to 20 °C. Fibres iso...

A self-catenated Zn(II)-organic framework formulated as [Zn2(3,3'-bpeab)(oba)2]·DMF (1) exhibiting a six-connected 44·610·8 topology has been successfully synthesized through the mixed-ligand of kinked 3,3'-bis[2-(4-pyridyl)ethenyl]azobenzene (3,3'-bpeab) and 4,4'-oxybis-benzoic acid (H2oba) under solvothermal condition. UV light triggers isomerization of complex 1 in a single-crystal-to-single...

Supplemental Experimental Procedures Confocal UV Laser Scanning Microscopy of Filipin-Sterol Fluorescence Dot-Blot Detection of Filipin-Sterol Fluorescence Analysis of Arabidopsis roots was performed by employing a Nikon Sterols (Sigma) and 4-cholesten-3-one (Sigma) in chloroform at 20 Diaphot 300 inverted microscope, connected to a Nikon RCM 8000 mM were spotted onto Transblot nitrocellulose m...

A capillary electrophoresis (CE)/optical fiber light-emitting diode (LED)-induced fluorescence detection method is developed for the determination of agmatine in biological samples. The agmatine was precolumn-derivatized with fluorescence tagging reagent, fluorescein isothiocyanate (FITC). Optimal separation and determination for agmatine were obtained with an electrophoretic buffer of 20 mM so...
