Toward a Rationale for the PTC124 (Ataluren) Promoted Readthrough of Premature Stop Codons: A Computational Approach and GFP-Reporter Cell-Based Assay

2014

The presence in the mRNA of premature stop codons (PTCs) results in protein truncation responsible for several inherited (genetic) diseases. A well-known example of these diseases is cystic fibrosis (CF), where approximately 10% (worldwide) of patients have nonsense mutations in the CF transmembrane regulator (CFTR) gene. PTC124 (3-(5-(2-fluorophenyl)-1,2,4-oxadiazol-3-yl)-benzoic acid), also known as Ataluren, is a small molecule that has been suggested to allow PTC readthrough even though its target has yet to be identified. In the lack of a general consensus about its mechanism of action, we experimentally tested the ability of PTC124 to promote the readthrough of premature termination c…

The on-line coupled atmospheric chemistry model system MECO(n) – Part 5: Expanding the Multi-Model-Driver (MMD v2.0) for 2-way data exchange includin…

2018

Abstract. As part of the Modular Earth Submodel System (MESSy), the Multi-Model-Driver (MMD v1.0) was developed to couple online the regional Consortium for Small-scale Modeling (COSMO) model into a driving model, which can be either the regional COSMO model or the global European Centre Hamburg general circulation model (ECHAM) (see Part 2 of the model documentation). The coupled system is called MECO(n), i.e., MESSy-fied ECHAM and COSMO models nested n times. In this article, which is part of the model documentation of the MECO(n) system, the second generation of MMD is introduced. MMD comprises the message-passing infrastructure required for the parallel execution (multiple programme mul…

Tratamiento jurídico de una enfermedad social. Los trastornos de la conducta alimentaria (TCA)

2018

The boundless increase of people suffering from an Eating Disorder (ED), makes necessary to develop measures related to other factors, in order to overcome the ones characterized of being strictly sanitary. The disease has become a social and cultural phenomenon. The exaltation of the cult to the body, with the stereotype of the extreme thinness linked with beauty and success is causing that, particularly young people, try to achieve an image which, in many cases, can jeopardize their health, that is the reason why the rearrangement of values has become an objective of paramount importance. Therefore, the fight against this social illness requires legal actions in order to prevent it from g…

Euparyphium albuferensis and Echinostoma friedi (Trematoda: Echinostomatidae): Experimental cercarial transmission success in sympatric snail communi…

2008

Euparyphium albuferensis and Echinostoma friedi cercarial infectivity to four species of sympatric snails was exam- ined under single- or multiple-choice laboratory conditions to show the level of parasite-snail host compatibility. Radix peregra, Lymnaea fuscus, Physella acuta and Gyraulus chinensis act as second intermediate hosts of both parasite species although differ- ent cercarial transmission success (CTS) was observed. In single-host experiments, R. peregra and P. acuta showed a high de- gree of compatibility with E. albuferensis, while only P. acuta in the case of E. friedi. In two-choice snail communities, a snail with high CTS increased the values of another with low compatibilit…

Dinner with the roommates: trophic niche differentiation and competition in a mutualistic ant‐ant association

2020

1. The potential for competition is highest among species in close association. Despite net benefits for both parties, mutualisms can involve costs, including food competition. This might be true for the two neotropical ants Camponotus femoratus and Crematogaster levior, which share the same nest in a presumably mutualistic association (parabiosis). 2. While each nest involves one Crematogaster and one Camponotus partner, both taxa were recently found to comprise two cryptic species that show no partner preferences and seem ecologically similar. Since these cryptic species often occur in close sympatry, they might need to partition their niches to avoid competitive exclusion. 3. Here, we in…

Ontogenetic Habitat Selection by Hadwenius pontoporiae (Digenea: Campulidae) in the Intestine of Franciscanas (Cetacea)

1997

The linear habitat selection of 4 sequential maturity stages (1, 2, 3, and 4) of the trematode Hadwenius pontoporiae in the intestines of 26 South American dolphins Pontoporia blanvillei was investigated. The franciscana is a suitable host for H. pontoporiae because all 26 hosts were infected, the infrapopulations being composed mostly of gravid (stage 4) worms. Most trematodes were found in the first third of the intestine. The niches of the maturity stages decreased from stage 1 to 4. Gravid worms favored the most anterior part of the duodenum, whereas stages 1, 2, and 3 occurred more posteriorly in every host. The distributions of the maturity stages showed a narrow site fidelity and wer…

Compensating acquitted pre-trial detainees

2015

Abstract Western legal systems are far from having provided the same solution to the problem of whether acquitted pre-trial detainees should be compensated for the harm suffered as a result of detention on remand. Various arguments have been formulated in order to justify or criticize this compensation, but the possible incentive effects of this compensation on criminal behavior has not yet been considered. This paper analyzes these effects, focusing on the case where detention was lawfully and diligently carried out by State agents, and not having been caused by negligence on the part of the detainee. The paper shows that such compensation can either deter crime or encourage it, depending …

Passive congregation based particle swam optimization (pso) with self-organizing hierarchical approach for non-convex economic dispatch

2017

This paper proposes a passive congregation based PSO with self-organizing hierarchical algorithm approach for solving the economic dispatch problem of power system, where some of the units have prohibited operating zones. This Algorithm is known to perform better than conventional gradient based optimization methods for non-convex optimization problems. Conventional PSO algorithm is a population based heuristic search, employing problem of premature convergence. In this work, an innovative approach based on the concept of passive congregation based PSO with self-organizing hierarchical approach is employed to overcome the problem of premature convergence in classical PSO method.

High order normal form construction near the elliptic orbit of the Sitnikov problem

2011

We consider the Sitnikov problem; from the equations of motion we derive the approximate Hamiltonian flow. Then, we introduce suitable action–angle variables in order to construct a high order normal form of the Hamiltonian. We introduce Birkhoff Cartesian coordinates near the elliptic orbit and we analyze the behavior of the remainder of the normal form. Finally, we derive a kind of local stability estimate in the vicinity of the periodic orbit for exponentially long times using the normal form up to 40th order in Cartesian coordinates.
