Fetal Pain Perception: Legislative Assertions and Developmental Neuroscience

open access: yesAnnals of the Child Neurology Society, EarlyView.
ABSTRACT Background Pain perception is a conscious experience, but neither pain nor consciousness is defined in the developing human fetus. Emergent consciousness may be regarded as a phenomenon that ultimately arises from an essential minimum of functional neuronal connectivity. Proposed U.S.

Nuclear dynamics: Formation of bodies and trafficking in plant nuclei

open access: yesFrontiers in Plant Science, 2022
The existence of the nucleus distinguishes prokaryotes and eukaryotes. Apart from containing most of the genetic material, the nucleus possesses several nuclear bodies composed of protein and RNA molecules.

Interactions of U2 Gene Loci and Their Nuclear Transcripts with Cajal (Coiled) Bodies: Evidence for PreU2 within Cajal Bodies [PDF]

open access: yesMolecular Biology of the Cell, 2000
The Cajal (coiled) body (CB) is a structure enriched in proteins involved in mRNA, rRNA, and snRNA metabolism. CBs have been shown to interact with specific histone and snRNA gene loci. To examine the potential role of CBs in U2 snRNA metabolism, we used a variety of genomic and oligonucleotide probes to visualize in situ newly synthesized U2 snRNA ...

Twenty years of dynamic occupancy models: a review of applications and look to the future

open access: yesEcography, EarlyView.
Since their introduction over 20 years ago, dynamic occupancy models (DOMs) have become a powerful and flexible framework for estimating species occupancy across space and time while accounting for imperfect detection. As their popularity has increased and extensions have further expanded their capabilities, DOMs have been applied to increasingly ...

SART3-Dependent Accumulation of Incomplete Spliceosomal snRNPs in Cajal Bodies

open access: yesCell Reports, 2015
Cajal bodies (CBs) are evolutionarily conserved nuclear structures involved in the metabolism of spliceosomal small nuclear ribonucleoprotein particles (snRNPs). CBs are not present in all cell types, and the trigger for their formation is not yet known.

Physiology–microhabitat matching may help organisms cope with the thermal and hydric challenges under climate change: a tale of two lizards

open access: yesEcography, EarlyView.
Climate change is significantly affecting biodiversity, and organisms that depend on external temperature – such as ectotherms – are particularly vulnerable to these effects. Microhabitats provide refuge for species, thereby reducing exposure to thermal and hydric stress under climate change.

Interchromatin granule clusters in vitellogenic oocytes of the flesh fly, Sarcophaga sp.

open access: yesFolia Histochemica et Cytobiologica, 2008
Insect oocyte nuclei contain different extrachromosomal nuclear bodies including Cajal bodies and interchromatin granule clusters (IGCs). In the present study, we describe IGC equivalents in the vitellogenic oocytes of the flesh fly, Sarcophaga sp. These

Hit and run versus long-term activation of PARP-1 by its different domains fine-tunes nuclear processes. [PDF]

open access: yes, 2019
Poly(ADP-ribose) polymerase 1 (PARP-1) is a multidomain multifunctional nuclear enzyme involved in the regulation of the chromatin structure and transcription.

Reversible Nuclear-Lipid-Droplet Morphology Induced by Oleic Acid: A Link to Cellular-Lipid Metabolism [PDF]

open access: yes, 2017
Neutral lipidsÐinvolved in many cellular processesÐare stored as lipid droplets (LD), thosemainly cytosolic (cLD) along with a small nuclear population (nLD).

Denervated Schwann cells attract macrophages by secretion of leukemia inhibitory factor (LIF) and monocyte chemoattractant protein-1 in a process regulated by interleukin-6 and LIF [PDF]

open access: yes, 2002
Injury to peripheral nerves results in the infiltration of immune cells, which remove axonal- and myelin-derived material. Schwann cells could play a key role in this process by regulating macrophage infiltration.
