The nuclear envelope — also called the nuclear membrane — consists of two membranes that surround the nucleus of plant and animal cells. Both the nucleus and the nuclear envelope were discovered by Scottish b
附两例病例: A. Axial T1-weighted sequence in a 53-year-old woman with a 3-month history of confusion demonstrates a a well-circumscribed,lobulated mass located in the frontal and parietal lobe, to be isointense to gray matter...
Who created the Bohr model? Essentials of the Bohr Model: The Bohr model describes the structure of an atom. It states that the nucleus is a small positive core and is surrounded by a cloud of electrons arranged in discrete energy levels. Prior to this model, it was thought that electrons...
The researchers analyzed data from 45 elderly people and found that people with fewer neurons in the "sleep switch" area were more probably to have sleepless nights."The fewer the neurons are, the more broken the sleep becomes. These findings show that the ventrolateral preoptic nucleus in ...
Increasing evidence suggests that a cross-talk mechanism between mitochondria and the nucleus is closely related to neuronal function and activity. Nuclear receptors (estrogen receptors, thyroid (T3) hormone receptor, peroxisome proliferators-activated receptor gamma2) and transcription factors (cAMP ...
and he's deciding on the producer". Roger is "basically through with preproduction and he's working with Alan Shacklock again." John has formed the nucleus of a new band with Lou Gramm-influenced vocalist Henry Small, keysman Andy Nye (ex-Michael Schenker Group) and drummer Zak Starkey. ...
When Dame Jocelyn Bell Burnell discovered the first pulsar 51 years ago, she revealed a new tool for solving many mysteries of the cosmos.
One can define latency as retention of viral genome in the nucleus of a cell for an extended period without pro- duction of infectious virions. Reactivation would then be the point at which virion formation occurs, which would permit limited viral gene expression without reactiva- tion. From ...
proteases, enzymes that break down proteins into their building blocks—amino acids. The proteases didn’t affect the precipitate, further cementing his view that this was not a protein. He also knew, based on previous work, that the substance was found in the nucleus, so he named it nuclei...
in sleep showed highe dopamine activity in three regions: the prefrontal cortex (前额叶皮质), nucleus accumbens (伏隔核) and hypothalamus(下丘脑).To figure out which areas were related to the mice's anti-depression effect, they silenced dopamine reaction in each of these areas of the brain....
