NuBBEDB: an updated database to uncover chemical and biological information from Brazilian biodiversity

open access: yesScientific Reports, 2017
The intrinsic value of biodiversity extends beyond species diversity, genetic heritage, ecosystem variability and ecological services, such as climate regulation, water quality, nutrient cycling and the provision of reproductive habitats it is also an ...

Prospects for the (Hyper)Nuclei Study in the Nica Energy Range

open access: yesParticles, 2023
The production of nuclei and hypernuclei is of interest for experimental and theoretical studies: it is a big question how such weakly bound objects survive in a hot, dense environment and which new insights on the heavy-ion collisions dynamics they can ...

Control of echolocation pulses by neurons of the nucleus ambiguus in the rufous horseshoe bat, Rhinolophus rouxi [PDF]

open access: yes, 1986
1. Horseradish peroxidase was applied by iontophoretic injections to physiologically identified regions of the laryngeal motor nucleus, the nucleus ambiguus in the CF/FM batRhinolophus rouxi. 2.

Interaction of antiprotons with nuclei [PDF]

open access: yesNuclear Physics A, 2015
We report on self-consistent calculations of $\bar{p}$ quasi-bound states in selected nuclei performed within the relativistic mean-field (RMF) model employing $\bar{p}$ coupling constants tuned to reproduce $\bar{p}$-atom data. We confirmed considerable polarization of the nuclear core induced by the antiproton.

Glucocorticoid receptor: translocation from the cytoplasm to the nuclei, chromatin and intranuclear chaperone cycles

open access: yesВавиловский журнал генетики и селекции, 2015
Glucocorticoid receptor (GR) is a ligand-dependent transcription factor, involved in the regulation of hundreds of genes. In the absence of any ligand, GR resides in the cytoplasm where it is sequestered in a multimeric chaperone complex consisting of ...

The Role of Selenium on the Formation of Spheroidal Graphite in Cast Iron

open access: yesMetals, 2021
Sulfur, an element that belongs to group 16 (chalcogens) of the periodic table, is an excellent promoter of nucleation substrates for graphite in cast iron.

Accurate detection of dysmorphic nuclei using dynamic programming and supervised classification [PDF]

open access: yes, 2017
A vast array of pathologies is typified by the presence of nuclei with an abnormal morphology. Dysmorphic nuclear phenotypes feature dramatic size changes or foldings, but also entail much subtler deviations such as nuclear protrusions called blebs.

Pairing in nuclei [PDF]

open access: yesPhysica Scripta, 2006
Simple generic aspects of nuclear pairing in homogeneous medium as well as in finite nuclei are discussed. It is argued that low-energy nuclear structure is not sensitive enough to resolve fine details of nuclear nucleon-nucleon (NN) interaction in general and pairing NN interaction in particular what allows for regularization of the ultraviolet (high ...

An ultra-low-power processor pipeline-structure

open access: yesDianzi Jishu Yingyong, 2019
With the rapid development of communication and chip technology, IoT will be an important part of the next generation of information technology, a powerful driving force to promote the intelligent process of our lives. Among the IoT terminal applications,

The Role of HO-1 and Its Crosstalk with Oxidative Stress in Cancer Cell Survival

open access: yesCells, 2021
Heme oxygenases (HOs) act on heme degradation to produce carbon monoxide (CO), free iron, ferritin, and biliverdin. Upregulation of cellular HO-1 levels is signature of oxidative stress for its downstream effects particularly under pro-oxidative status ...
