High genetic stability of potato yellow mosaic Panama virus infecting tomato in Panama
2018
The relevant regions in Panama involved in commercial tomato production, including the Chiriqui, Veraguas, Herrera, Los Santos and Panama Oeste provinces, were surveyed for the distribution and genetic diversity of potato yellow mosaic Panama virus (PYMPV) in the growing seasons of 2011 and 2012. A total of 28 tomato plots were surveyed and 314 individual tomato plants were sampled. DNA was extracted from each plant for a subsequent rolling circle amplification (RCA) analysis, to confirm the presence of begomovirus infections. The samples displaying a positive RCA reaction were subsequently analysed by PCR with a specific primer pair to identify PYMPV. This virus was detected in samples col…
Targeting Nonsense: Optimization of 1,2,4-Oxadiazole TRIDs to Rescue CFTR Expression and Functionality in Cystic Fibrosis Cell Model Systems
2020
Cystic fibrosis (CF) patients develop a severe form of the disease when the cystic fibrosis transmembrane conductance regulator (CFTR) gene is affected by nonsense mutations. Nonsense mutations are responsible for the presence of a premature termination codon (PTC) in the mRNA, creating a lack of functional protein. In this context, translational readthrough-inducing drugs (TRIDs) represent a promising approach to correct the basic defect caused by PTCs. By using computational optimization and biological screening, we identified three new small molecules showing high readthrough activity. The activity of these compounds has been verified by evaluating CFTR expression and functionality after…
Safflower Yellow and Its Main Component HSYA Alleviate Diet-Induced Obesity in Mice: Possible Involvement of the Increased Antioxidant Enzymes in Liv…
2020
PurposeOxidative stress plays an important role in the pathogenesis of obesity and its associated disorders. Safflower yellow (SY) and hydroxysafflor yellow A (HSYA), the natural compounds isolated from Carthamus tinctorius L., has been found to possess antioxidative and anti-obesity properties. The purpose of the present study is to investigate whether SY and its main component HSYA alleviate obesity by the antioxidant effects.MethodsDiet-induced obese (DIO) mice were treated with 200 mg/kg/d SY or HSYA for 10 weeks. Body weight, fat mass, serum biochemical parameters and superoxide dismutase (SOD) activities were measured. Glucose and insulin tolerance tests were performed. The expression…
Chromosome-scale assembly of the yellow mealworm genome
2022
Background: The yellow mealworm beetle, Tenebrio molitor, is a promising alternative protein source for animal and human nutrition and its farming involves relatively low environmental costs. For these reasons, its industrial scale production started this century. However, to optimize and breed sustainable new T. molitor lines, the access to its genome remains essential. Methods: By combining Oxford Nanopore and Illumina Hi-C data, we constructed a high-quality chromosome-scale assembly of T. molitor. Then, we combined RNA-seq data and available coleoptera proteomes for gene prediction with GMOVE. Results: We produced a high-quality genome with a N50 = 21.9Mb with a completeness of 99.5% an…
El Grand Débat National de Francia : análisis de un proceso participativo multicanal.
2021
En una época de cambios tecnológicos y sociales, la ciudadanía demanda nuevos canales de participación pública. En los últimos tiempos distintos procesos de participación recurren a la opinión ciudadana para adoptar decisiones. El movimiento de los chalecos amarillos desencadenó una ola de protestas en Francia a la que quiso hacerse frente con el Grand Débat National, un proceso participativo multicanal, a distintos niveles administrativos. El estudio de su desarrollo y resultados debe servir para diseñar futuros procesos similares.

Chromophobe cell renal carcinoma and its variants--a report on 32 cases.
1988
This paper reports on 32 chromophobe cell renal carcinomas observed in 697 renal cell cancers (RCC) of adults (peak in the sixth decade of life). The chromophobe cell-type differs from other types of RCC macroscopically, the cut-surface being predominantly of grey-beige colour. Histologically, there are two variants: one is the typical (light) variant (n = 22) and the other is eosinophilic (n = 10). Both variants have in common (a) reaction of the cytoplasm with Hale's acid iron colloid; (b) electron microscopic detection of cytoplasmic microvesicles (150-300 nm), frequently with 'inner vesicles', and (c) low glycogen content in comparison with the clear cell carcinoma. Immunocytochemical i…
Blue-yellow deficiencies in young moderate smokers.
2021
Purpose To evaluate whether tobacco affects color vision in young moderate smokers. Methods Chromatic mechanisms of 13 moderate smokers (10–20 cigarettes/day and at least 5 years smoking) and 17 non-smokers in the 18–35 age range were assessed with the Farnsworth-Munsell 100-hue (FM100h) test and short wavelength automated perimetry (SWAP). Results FM100h Total Error Scores (TES) were higher for smokers, and although differences were not significant (p = 0.14), a linear model with principal component analysis was able to explain 95% of the variance in TES and red-green partial error scores, though not in blue-yellow partial error scores (p = 0.07), using the number of years as smokers and t…
Modulation of La Crosse virus infection in Aedes albopictus mosquitoes following larval exposure to coffee extracts
2013
This commentary highlights key points, basic ideas, and future outlooks presented by Eastep et al. (2012) in Frontiers in Physiology-Systems Biology. The authors have provided an interesting investigation about the successful use of an environmentally friendly product derived from plants as a larvicidal agent to control mosquito populations as well as a substance that could alter the vector competence of mosquitoes for arthropod-borne viruses (arboviruses). Specifically Eastep and collaborators used coffee extracts (with and without caffeine) to try to answer two hypothesis: first, coffee extracts could have good results as a mosquitocidal compounds applied in larval biotopes and second, vi…
