Pseudoallencotyla gen. n., a new genus for Allencotyla pricei (Kritsky, Noble et Moser, 1978) (Monogenea: Heteraxinidae), with a key to genera of Het…
2003
In this study, we clarify the taxonomic status of Allencotyla pricei based on a re-examination of paratypes and voucher specimens. Four important characters are added to previous descriptions: the vagina is ventral; the cirrus is absent; the eggs are fusiform and have two polar filaments (one about 3.5 times longer than the other); and, there are two flat sclerites at each side of the dorsal trident-shaped sclerite in the clamps. A comparison of A. pricei with species from all the genera of the Heteraxininae, including Allencotyla mcintoshi, indicates that A. pricei has several exclusive characters, i.e., a ventral vagina, vaginal armature, two additional dorsal sclerites in the clamps, a v…
Three New Species of the Bothriomirine Genus Leprocapsus Poppius from Indonesia (Hemiptera: Heteroptera: Miridae: Cylapinae)
2012
Abstract Three new species of the genus Leprocapsus Poppius from Indonesia, L. irianjayensis n. sp. and L. parvus n. sp. (Irian Jaya), and L. schuhi n. sp. (Sulawesi), are described. A color photograph of the adult and illustration of the antennal segments I and II of each treated taxa, dorsal habitus drawing of L. schuhi, illustration of the male genitalia of L. parvus, and scanning electron micrographs of selected structures of L. irianjayensis, L. schuhi, and L. scutellaris are provided. A key to all known species, diagnosis and the distribution map of the genus Leprocapsus are given.
Forward rapidity isolated photon production in proton-nucleus collisions
2018
We calculate isolated photon production at forward rapidities in proton-nucleus collisions in the Color Glass Condensate framework. Our calculation uses dipole cross sections solved from the running coupling Balitsky-Kovchegov equation with an initial condition fit to deep inelastic scattering data and extended to nuclei with an optical Glauber procedure that introduces no additional parameters beyond the basic nuclear geometry. We present predictions for future forward RHIC and LHC measurements. The predictions are also compared to updated results for the nuclear modification factors for pion production, Drell-Yan dileptons and $J/\psi$ mesons in the same forward kinematics, consistently c…
Droits européens et droit de la famille : contribution à l'étude de la dynamique du rapprochement
2011
In Europe, there's now a trend for the standardization of national family laws.This is closely linked to the increase of sources. The Council of Europe’s right, the European Union’s right, and the Comparative Law are increasingly interfering with the inner process of the production of family laws.The uniform standardization of family Laws first and foremost originates in the interaction of sources.The relationship between the different european legal systems, whether national or supranational, cannot only be seen as hierarchic or horizontal.They are indeed much more complicated and are based upon communication i.e. based on exchange and mutual influence. Communication between the different …
The In Silico Fischer Lock-and-Key Model: The Combined Use of Molecular Descriptors and Docking Poses for the Repurposing of Old Drugs
2019
Not always lead compound and/or derivatives are suitable for the specific biological target for which they are designed but, in some cases, discarded compounds proved to be good binders for other biological targets; therefore, drug repurposing constitute a valid alternative to avoid waste of human and financial resources. Our virtual lock-and-key methods, VLKA and Conf-VLKA, furnish a strong support to predict the efficacy of a designed drug a priori its biological evaluation, or the correct biological target for a set of the selected compounds, allowing thus the repurposing of known and unknown, active and inactive compounds.
SF3B1 modulators affect key genes in metastasis and drug influx: a new approach to fight pancreatic cancer chemoresistance.
2021
Aim: Because mutations of splicing factor 3B subunit-1 (SF3B1) have been identified in 4% of pancreatic ductal adenocarcinoma (PDAC) patients, we investigated the activity of new potential inhibitors of SF3B1 in combination with gemcitabine, one of the standard drugs, in PDAC cell lines. Methods: One imidazo[2,1-b][1,3,4]thiadiazole derivative (IS1) and three indole derivatives (IS2, IS3 and IS4), selected by virtual screening from an in-house library, were evaluated by the sulforhodamine-B and wound healing assay for their cytotoxic and antimigratory activity in the PDAC cells SUIT-2, Hs766t and Panc05.04, the latter harbouring the SF3B1 mutations. The effects on the splicing pattern of pr…
In situ delivery of corticosteroids for treatment of oral diseases.
2017
In many mucocutaneous disorders, corticosteroids therapy is currently central. Systemic therapy is restricted to severe disorders whereas topical applications are considered as the first-line treatment. The oral cavity environment, the medication form and other factors related to the delivery method are key factors for the therapy efficiency and effectiveness. Current marketed medications are not able to avoid wrong drug exposure and scarce patients’ compliance. Innovative in situ delivery systems are able to prolong the drug retention time on the mucosa and to avoid the drawbacks of conventional formulations. This review is intended to give a general overview of oral mucocutaneous patholo…
Lifespan-Aware Routing for Wireless Sensor Networks
2010
Wireless Sensor Networks (WSNs) have the capability to become the eyes and ears for the future networked society allowing monitoring of any habitat or object's properties remotely and independently of an energy source. Services based on this technology may change the way we monitor and control remote areas and objects. In this paper we propose a different approach to routing data across Wireless Sensor Networks. We argue that a distance-vector protocol using a lifespan-aware metric is a plausible solution to the task of routing information in WSN in a manner that both saves energy of the individual node and manages summarized energy of the system equally and fairly. The concept is designed …
Overload breakdown in models for photosynthesis
2015
In many models of the Calvin cycle of photosynthesis it is observed that there are solutions where concentrations of key substances belonging to the cycle tend to zero at late times, a phenomenon known as overload breakdown. In this paper we prove theorems about the existence and non-existence of solutions of this type and obtain information on which concentrations tend to zero when overload breakdown occurs. As a starting point we take a model of Pettersson and Ryde-Pettersson which seems to be prone to overload breakdown and a modification of it due to Poolman which was intended to avoid this effect.
Effects of modulation of body fat in production of adiponectin in mice : consequences on hepatic metabolism of lipids
2010
Adiponectin (ApN), a 30-kDa adipokine abundantly produced by adipose tissue has been described for the first time in 1995. Early findings demonstrating serum adiponectin levels are inversely correlated with obesity initiated intense investigation of the relationship between adiponectin and all symptoms of the metabolic syndrome. Of these studies, strong evidence suggests that a weight loss induced by medication or hypocaloric diet led to increased circulating ApN levels and improvement of biochemical parameters. Thus, high levels of ApN have been correlated with an improvement of insulin sensitivity and lipid parameters reducing cardiovascular risk. However mechanisms involved in the improv…
