Estrous behavior in rodents is triggered by the binding of progesterone (P) to its intracellular receptor (PR). Non‐steroidal agents (i.e., gonadotropin‐releasing hormone, noradrenaline, dopamine and others), acting at the membrane, can facilitate estrous behavior in estrogen‐primed rats. This action is mediated through the generation of second messengers (cyclic AMP, cyclic GMP, calcium) which, in turn, phosphorylate through diverse kinase systems (protein kinases A, G or C) either the PR or associated ...

The CXCR4/CXCL12 axis has been extensively associated with different types of cancer correlating with higher aggressiveness and metastasis. In diffuse large B-cell lymphoma (DLBCL), the expression of the chemokine receptor CXCR4 is involved in the dissemination of malignant B cells and is a marker of poor prognosis. CXCR7 is a chemokine receptor that binds to the same ligand as CXCR4 and regulates de CXCR4-CXCL12 axis. These findings together with the report of CXCR7 prognostic value in several tumor ...

To reap its full benefits, 5G must evolve into a scalable decentralized architecture by exploiting intelligence ubiquitously and securely across different technologies, network layers, and segments. In this article, we propose end-to-end and ubiquitous secure machine learning (ML)-powered intent-based networking (IBN). The IBN framework is aware of its state and context to autonomously take proactive actions for service assurance. It is integrated in a zero-touch control and orchestration framework ...

The degradation of Metoprolol (MET) by photo-Fenton was studied in different photoreactors. The importance of the irradiation source, UVC (λ = 254 nm), black blue lamps (λ = 365 nm) and simulated sunlight, was investigated at lab-scale experiments. Moreover, compound parabolic collectors (CPC), at pilot-scale with sunlight, have been also applied. Photo-Fenton treatment employing black blue lamps gave the best results, in terms of mg MET removal per accumulated energy. Using the highest Fe2+ (10 mg/L) and ...

This study investigates the variation of different parameters such as MET concentration, total organic carbon (TOC), chemical oxygen demand (COD) per accumulated energy (determined by actinometries), analyzing the performance of the different set-ups tested. First order apparent rate constants were calculated for the systems. Nearly total MET removal was achieved through ...

Background For years, the genetics of metastatic colorectal cancer (CRC) have been studied using a variety of techniques. However, most of the approaches employed so far have a relatively limited resolution which hampers detailed characterization of the common recurrent chromosomal breakpoints as well as the identification of small regions carrying genetic changes and the genes involved in them. Methodology/Principal Findings Here we applied 500K SNP arrays to map the most common chromosomal lesions ...

Progesterone exerts a variety of actions in the brain through the interaction with its receptors (PR) which have two isoforms with different function and regulation: PR-A and PR-B. Progesterone may modulate neurotransmission by regulating the expression of neurotransmitters synthesizing enzymes or their receptors in several brain regions. The role of PR isoforms in this modulation is unknown. We explored the role of PR isoforms in the regulation of tryptophan (TPH) and tyrosine (TH) hydroxylase, and ...

Estrous behavior induced by progesterone (P) treatment of estradiol-primed rats is followed by a period in which females do not respond behaviorally to a second administration of P [sequential inhibition (SI)]. SI is thought to involve P-dependent down-regulation of hypothalamic P receptor (PR) content. This study tested the hypothesis that the 26S proteasome participates in the regulation of SI and brain PR content in female rats. Ovariectomized, estrogen-primed (estradiol benzoate, 2 μg sc) adult rats ...

Maximum entropy procedures for estimating coarse-grain parameters from molecular dynamics (MD) simulation data are considered within the specific context of the sequence-dependent cgDNA rigid-base model of DNA. We describe a quite general approach that exploits a maximum absolute entropy principle to fit an observed matrix of covariances subject to the constraint of only allowing a prescribed sparsity pattern of nearest-neighbor interactions in the free energy. We also allow indefinite local stiffness- ...
