Targeting Glioblastoma Stem Cells through Disruption of the Circadian Clock.

open access: yesCancer Discovery, 2019
Glioblastomas are highly lethal cancers, containing self-renewing glioblastoma stem cells (GSCs). Here, we show that GSCs, differentiated glioblastoma cells (DGCs), and non-malignant brain cultures all displayed robust circadian rhythms, yet GSCs alone ...

Endoplasmic reticulum–nuclei signaling enzyme-1 knockdown modulates effect of hypoxia and ischemia on the expression of circadian genes in glioma cells

open access: yesБіологічні студії, 2011
The main molecular components of circadian clock system are proteins which play a significant role in the control of both metabolism and malignant tumor growth.

Zegar tyka

open access: yesAutobiografia, 2021
The author briefly justifies the concept of chronopoetics. He refers to Lec’s aphorism, to Aleksander Wat’s poetry and his autobiographical prose. Chronopoetics exposes the clock as an object presented in literature and as a carrier of philosophical ...

Electricity and Clocks [PDF]

open access: yesNature, 1887
THE exact combination about which Mr. Wilson inquires is already in existence: it can be seen at 2, Garfield Buildings, Gray's Inn Road, in the Jensen electric bell factory. The arrangement used by Mr. Jensen—and it seems to me preferable to that suggested by Mr.

Tree of Life Reveals Clock-Like Speciation and Diversification [PDF]

open access: yesMolecular biology and evolution, 2014
Genomic data are rapidly resolving the tree of living species calibrated to time, the timetree of life, which will provide a framework for research in diverse fields of science. Previous analyses of taxonomically restricted timetrees have found a decline

Non-obesogenic doses of palmitate disrupt circadian metabolism in adipocytes

open access: yesAdipocyte, 2019
Saturated fatty acids, such as palmitate, lead to circadian disruption. We aimed at studying the effect of low doses of palmitate on circadian metabolism and to decipher the mechanism by which fatty acids convey their effect in adipocytes.

Hypothesis: Cryptochromes and brown fat are essential for adaptation and affect mood and mood-related behaviors.

open access: yesFrontiers in Neurology, 2012
Solar radiation and ambient temperature have acted as selective physical forces among populations and thereby guided species distributions in the globe.

Electricity and Clocks [PDF]

open access: yesNature, 1886
IN the absence of any details, apparently Mr. Wilson's simplest plan would be to insulate the hammer and bell of his “small striking clock,” and arrange that a galvanic current should pass through both, when they come in contact by the act of striking: this current of course to be directed to a large electro-magnet, to raise the hammer for striking on ...

Inexpensive programmable computer clock [PDF]

open access: yes, 1973
Clock's computer interface accepts pulses from computer (computer commands) and translates them into control signals for clock, and vice versa. Clock is preset by computer to a fixed number of time pulses, and then started.
