Evaluation of genetic variability and relatedness among eight Centaurea species through CAAT-box derived polymorphism (CBDP) and start codon targeted…

2021

Centaurea is a value-ultimate genus of medicinal plants showing high diversification levels, especially within the Mediterranean basin, and is still traditionally recognized as a complicated taxon. So far, few studies utilizing molecular markers have been done on Centaurea spp. towards a better dissection of its phylogeny and accurate assessment of genetic diversity. Here, two functional marker systems, start codon targeted (SCoT) polymorphism and CAAT box-derived polymorphism (CBDP), were implemented to assess the genetic diversity between eight wild Centaurea species in Egypt. Seventeen SCoT and 19 CBDP primers generated 197 and 179 bands, respectively. These primers generated 158 (80.2%)…

Legionella pneumophila pangenome reveals strain-specific virulence factors

2010

Abstract Background Legionella pneumophila subsp. pneumophila is a gram-negative γ-Proteobacterium and the causative agent of Legionnaires' disease, a form of epidemic pneumonia. It has a water-related life cycle. In industrialized cities L. pneumophila is commonly encountered in refrigeration towers and water pipes. Infection is always via infected aerosols to humans. Although many efforts have been made to eradicate Legionella from buildings, it still contaminates the water systems. The town of Alcoy (Valencian Region, Spain) has had recurrent outbreaks since 1999. The strain "Alcoy 2300/99" is a particularly persistent and recurrent strain that was isolated during one of the most signifi…

A propósito de la inalterabilidad e intangibilidad del patrimonio genético humano como bien digno de protección penal

2019

En el presente estudio se efectúa una reflexión sobre el delito de manipulación genética contemplado en el artículo 159 del Código penal, precepto cuya concreta regulación despierta numerosas objeciones, especialmente en atención al bien jurídico de carácter colectivo que protege, como es la identidad genética, cuestionándose si esta conducta en particular encontraría mejor acomodo en la legislación administrativa. This paper makes a reflection on the crime of genetic manipulation contemplated in Article 159 of the Criminal Code, a provision whose specific regulation raises many objections, especially in attention to the collective legal right that protects, such as genetic identity, questi…

Cancer survival in Europe 1999-2007 by country and age: results of EUROCARE--5-a population-based study

2013

Background: Cancer survival is a key measure of the effectiveness of health-care systems. EUROCARE-the largest cooperative study of population-based cancer survival in Europe-has shown persistent differences between countries for cancer survival, although in general, cancer survival is improving. Major changes in cancer diagnosis, treatment, and rehabilitation occurred in the early 2000s. EUROCARE-5 assesses their effect on cancer survival in 29 European countries. Methods: In this retrospective observational study, we analysed data from 107 cancer registries for more than 10 million patients with cancer diagnosed up to 2007 and followed up to 2008. Uniform quality control procedures were a…

Characterization of Metabolically Healthy Obese People and Metabolically Unhealthy Normal-Weight People in a General Population Cohort of the ABCD St…

2017

There is actually no consensus about the possibility that in some instances, obesity may be a benign metabolically healthy (MH) condition as opposed to a normal-weight but metabolically unhealthy (MUH) state. The aim of this study was to characterize MH condition and to investigate possible associations with metabolic and cardiovascular complications. One thousand nineteen people (range of age 18–90 years) of the cohort of the ABCD_2 study were investigated. Participants were classified as normal weight (BMI < 24.9 kg/m2) or overweight-obese (BMI ≥25 kg/m2); they were also classified as MH in the presence of 0-1 among the following conditions: (a) prediabetes/type 2 diabetes, (b) hyperte…

Effects of repeated short episodes of environmental acidification on Atlantic salmon (Salmo salar) from a landlocked population

2020

Abstract Chronic or repeated exposure to environmental contaminants may result in allostatic overload, a physiological situation in which the costs of coping affect long-term survival and reproductive output. Continuous measurements in Otra, the largest river in southern Norway, show the occurrence of repeated 24–48 h episodes of acidification. This work investigates the impact of repeated short acidification episodes on a unique land-locked population of normally anadromous Atlantic salmon (“Bleke”). This was done by recording physiological measures of stress and allostatic load in fish exposed for 7 days to continuous or repeated episodes of simulated environmental acidification or untrea…

Analysis of composition, morphology, and biosynthesis of cuticular wax in wild type bilberry (Vaccinium myrtillus L.) and its glossy mutant

2021

Abstract In this study, cuticular wax load, its chemical composition, and biosynthesis, was studied during development of wild type (WT) bilberry fruit and its natural glossy type (GT) mutant. GT fruit cuticular wax load was comparable with WT fruits. In both, the proportion of triterpenoids decreased during fruit development concomitant with increasing proportions of total aliphatic compounds. In GT fruit, a higher proportion of triterpenoids in cuticular wax was accompanied by a lower proportion of fatty acids and ketones compared to WT fruit as well as lower density of crystalloid structures on berry surfaces. Our results suggest that the glossy phenotype could be caused by the absence o…

Rapid adaptation of signaling networks in the fungal pathogen Magnaporthe oryzae

2019

Abstract Background One fundamental question in biology is how the evolution of eukaryotic signaling networks has taken place. “Loss of function” (lof) mutants from components of the high osmolarity glycerol (HOG) signaling pathway in the filamentous fungus Magnaporthe oryzae are viable, but impaired in osmoregulation. Results After long-term cultivation upon high osmolarity, stable individuals with reestablished osmoregulation capacity arise independently from each of the mutants with inactivated HOG pathway. This phenomenon is extremely reproducible and occurs only in osmosensitive mutants related to the HOG pathway – not in other osmosensitive Magnaporthe mutants. The major compatible so…
