Cis‐unsaturated sphingolipids support growth of sphingoid base‐deficient yeast but impair plasma membrane integrity

open access: yesFEBS Open Bio, EarlyView.
Sphingoid base structures, the sphingolipid backbones, vary among species. We established yeast cells in which the native sphingoid base was replaced with plant‐type bases containing cis or trans double bonds. This is, to our knowledge, the first eukaryotic model mostly composed of sphingolipids containing cis‐unsaturated sphingoid base, providing a ...

Porous glass makes effective substrate for ozone-sensing reagent [PDF]

open access: yes, 1965
Porous-glass substrate is used for absorption of a dye used in measuring the concentration of atmospheric ozone at high altitudes. This measurement is based on the chemiluminescence produced in the reaction between ozone and the dye, rhodamine B.

Development of an Ion-Sensor using Fluorescence Resonance Energy Transfer

open access: yes, 2014
A method is presented for the sensing of ions by determining the concentration of corresponding salts (KCl, NaCl, MgCl2, CaCl2, FeCl3, FeSO4, AlCl3) in water, based on Fluorescence resonance energy transfer (FRET) process.

Irisin evokes bradycardia by activating cardiac-projecting neurons of nucleus ambiguus. [PDF]

open access: yes, 2015
Irisin is a newly identified hormone induced in muscle and adipose tissues by physical activity. This protein and its encoding gene have been identified in the brain; in addition, the precursor for irisin, FNDC5, can cross the blood-brain barrier.

Optical Spectral Study of Rhodamine Dyes Mixture Solution in Chloroform [PDF]

open access: yesEngineering and Technology Journal, 2013
The spectral properties (absorption and fluorescence) of laser dyes (Rhodamine6G, Rhodamine 3GO and Rhodamine B) mixture have been studied. This type of laser dye belongs to the Xanthenes family, it has dissolved in chloroform to prepare (1*10-5 M) in ...

Practical Broad-Band Tuning of Dye Lasers by Solvent Shifting [PDF]

open access: yes, 1986
We have operated a dye laser over a broad wavelength range (593.8-667.0nm) by shifting the dye emission profile with incremental changes of solvent composition. This was accomplished with the laser operating continuously, and only minor adjustment of the

In Situ Constructed Magnetic Core‐Shell Hydrogen‐Bonded Organic Framework‐on‐Metal–Organic Framework Structure: an Efficient Catalyst for Peroxymonosulfate Activation

open access: yesAdvanced Functional Materials, EarlyView.
In this work, a magnetic core‐shell catalyst (HOF‐on‐Fe3O4/ZIF‐67) is successfully synthesized, consisting of a metal–organic framework (ZIF‐67) with magnetic Fe3O4 as the core and a porous hydrogen‐bonded organic framework (HOF) as the shell. The catalyst efficiently activated peroxymonosulfate, resulting in rapid and effective removal of water ...
