The identity of the tropical African Polichne mukonja Griffini, 1908 (Orthoptera, Tettigoniidae, Phaneropterinae)

2016

Polichne mukonja Griffini, 1908 from Cameroon was hitherto known only from the holotype preserved at the Royal Belgian Institute of Natural Sciences, Brussels. This was probably due to the fact that the genus Polichne Stål, 1874 distributed only in Australia and Papua New Guinea. In view of this distribution, the tropical African species was therefore overlooked in the African literature. The recent discovery of two specimens at the Naturhistorisches Museum, Vienna, now provides us with a better understanding of the identity of this taxon, which is related to the African genus Catoptropteryx Karsch, 1890. Polichne mukonja is here transferred to a new genus Griffinipteryx and both taxa are p…

Positive solutions for nonlinear Robin problems

2017

We consider a parametric Robin problem driven by the p-Laplacian with an indefinite potential and with a superlinear reaction term which does not satisfy the Ambrosetti-Rabinowitz condition. We look for positive solutions. We prove a bifurcation-type theorem describing the nonexistence, existence and multiplicity of positive solutions as the parameter varies. We also show the existence of a minimal positive solution $\tilde{u}_\lambda$ and establish the monotonicity and continuity of the map $\lambda\to \tilde{u}_\lambda$.

Identification of mycorrhiza-regulated genes with arbuscule development-related expression profile

2004

Suppressive subtractive hybridisation was applied to the analysis of late stage arbuscular mycorrhizal development in pea. 96 cDNA clones were amplified and 81, which carried fragments more than 200 nt in size, were sequence analysed. Among 67 unique fragments, 10 showed no homology and 10 were similar to sequences with unknown function. RNA accumulation of the corresponding 67 genes was analysed by hybridisation of macro-arrays. The cDNAs used as probes were derived from roots of wild type and late mutant pea genotypes, inoculated or not with the AM fungus Glomus mosseae. After calibration, a more than 2.5-fold mycorrhiza-induced RNA accumulation was detected in two independent experiments…

Targeting the Activin Receptor Signaling to Counteract the Multi-Systemic Complications of Cancer and Its Treatments

2021

Muscle wasting, i.e., cachexia, frequently occurs in cancer and associates with poor prognosis and increased morbidity and mortality. Anticancer treatments have also been shown to contribute to sustainment or exacerbation of cachexia, thus affecting quality of life and overall survival in cancer patients. Pre-clinical studies have shown that blocking activin receptor type 2 (ACVR2) or its ligands and their downstream signaling can preserve muscle mass in rodents bearing experimental cancers, as well as in chemotherapy-treated animals. In tumor-bearing mice, the prevention of skeletal and respiratory muscle wasting was also associated with improved survival. However, the definitive proof tha…

In-depth characterization of denitrifier communities across different soil ecosystems in the tundra

2022

Abstract Background In contrast to earlier assumptions, there is now mounting evidence for the role of tundra soils as important sources of the greenhouse gas nitrous oxide (N2O). However, the microorganisms involved in the cycling of N2O in this system remain largely uncharacterized. Since tundra soils are variable sources and sinks of N2O, we aimed at investigating differences in community structure across different soil ecosystems in the tundra. Results We analysed 1.4 Tb of metagenomic data from soils in northern Finland covering a range of ecosystems from dry upland soils to water-logged fens and obtained 796 manually binned and curated metagenome-assembled genomes (MAGs). We then sear…

INFLUENCE OF FAMILY HISTORY OF TYPE 2 DIABETES ON PHENOTYPE AND PERFORMANCE IN YOUNG PEOPLE OF BOTH SEX.

2010

The type 2 diabetes is commonly considered a complex genetic disease, resulting from interactions between multiple genes and environmental factors without any single factor having strong independent effects. We studied the influence of family history to type 2 diabetes on physical phenotype of 47 health adolescents. In both sexes groups with positive family history (FH+) had the highest values of stature and body weight (p<0.05 for males, not significant for females), waist circumference (p<0.05 for males, not significant for females), and wrist circumference (p=0.05 for males, not significant for females). Considering performance, FH+ males showed a significant higher performance in power …

Family history to type 2 diabetes influence on body parameters of young soccer players

2011

The aim of our study was to analyze the difference of phenotype in healthy soccer players with family history of type 2 diabetes and healthy soccer players without family history of type 2 diabetes. The anthropometric parameters and body composition was analysed. The group with positive family history (FH+) had the highest values of wrist circumference (p<0.05) associated with not statistically significant increase of body fat mass and fat free mass. Also, the heart function was analysed. FH+ players had a diastolic basal pressure values higher than other group, but other functional parameters were the same. Analysing lung function indicators, FH+ players showed significant greater FEV1 and…

A class of multivariate type I generalized logistic distributions

2010

The logistic distribution has found important applications in many different fields and several different forms of generalizations have been proposed in the literature. However it seems, with a few exceptions, that there are not in the literature forms of multivariate generalized logistic distributions. In this paper we focus on the type I generalized logistic distribution and, based on a procedure of multivariate transformation of multivariate exponential distributions, we introduce a class of multivariate type I generalized logistic distributions. We provide some examples of bivariate and multivariate distributions of this class.
