The rotation and coma profiles of comet C/2004 Q2 (Machholz) [PDF]

, 2007
Aims. Rotation periods of cometary nuclei are scarce, though important when studying the nature and origin of these objects. Our aim is to derive a rotation period for the nucleus of comet C/2004 Q2 (Machholz). Methods. C/2004 Q2 (Machholz) was monitored

Comparison of the Effects of Electrolytic and Chemical Destruction of the Red Nucleus on the Compensatory Capacity of Rats With Rubrospinal Tract Lesions

Neural Plasticity, 1999
Transection of the rubrospinal tract in rats, performed before lesion of the red nucleus, resulted in the facilitated recovery of motor activity and operantly conditioned reflexes. Such facilitation was absent when the red nucleus is lesioned alone. This

The circumnuclear environment of the peculiar galaxy NGC 3310 [PDF]

, 2009
Gas and star velocity dispersions have been derived for eight circumnuclear star-forming regions (CNSFRs) and the nucleus of the spiral galaxy NGC3310 using high resolution spectroscopy in the blue and far red.

Combined Application of Quantitative Susceptibility Mapping and Diffusion Kurtosis Imaging Techniques to Investigate the Effect of Iron Deposition on Microstructural Changes in the Brain in Parkinson’s Disease

Frontiers in Aging Neuroscience, 2022
ObjectivesBrain iron deposition and microstructural changes in brain tissue are associated with Parkinson’s disease (PD). However, the correlation between these factors in Parkinson’s disease has been little studied.

Brain afferents to the lateral caudal ventrolateral medulla : a retrograde and anterograde tracing study in the rat [PDF]

, 2003
The ventrolateral medulla (VLM) modulates autonomic functions, motor reactions and pain responses. The lateralmost part of the caudal VLM (VLMlat) was recently shown to be the VLM area responsible for pain modulation.

Rhythmic glucose metabolism regulates the redox circadian clockwork in human red blood cells

Nature Communications, 2021
Red blood cells, which do not possess a nucleus, have circadian redox rhythms with incompletely understood regulatory mechanisms. Here the authors show that glucose metabolism plays a crucial role in regulating circadian redox status of human red blood ...

Arabidopsis FHY1 and FHY1-LIKE Are Not Required for Phytochrome A Signal Transduction in the Nucleus

Plant Communications, 2020
Photoreceptors of the phytochrome family control a multitude of responses in plants. Phytochrome A (phyA) is essential for far-red light perception, which is important for germination and seedling establishment in strong canopy shade.
