Multi-omics data integration provides insights into the post-harvest biology of a long shelf-life tomato landrace.

In this study we investigated the transcriptome and epigenome dynamics of the tomato fruit during post-harvest in a landrace belonging to a group of tomatoes (Solanum lycopersicum L.) collectively known as "Piennolo del Vesuvio", all characterized by a long shelf-life. Expression of protein-coding genes and microRNAs as well as DNA methylation patterns and histone modifications were analysed in distinct post-harvest phases.

Tomato genomic prediction for good performance under high-temperature and identification of loci involved in thermotolerance response.

Many studies showed that few degrees above tomato optimum growth temperature threshold can lead to serious loss in production. Therefore, the development of innovative strategies to obtain tomato cultivars with improved yield under high temperature conditions is a main goal both for basic genetic studies and breeding activities. In this paper, a F4 segregating population was phenotypically evaluated for quantitative and qualitative traits under heat stress conditions.

Percutaneous suture-mediated patent foramen ovale closure: two-year clinical follow-up.

Background: Percutaneous suture-mediated patent foramen ovale (PFO) closure has been recently introduced in clinical practice showing a favorable efficacy and safety profile in most PFO cases. The aim of this study was to assess the long-term outcomes of PFO closure by direct suture in a large consecutive series of patients.

Methods: We extracted all consecutive patients who underwent percutaneous closure of the PFO by suture technique (HeartStitch, Fountain Valley, CA, USA) from June 2016 with a follow-up of at least 2 years.

Perclose Proglide™ for vascular closure.

In the past 20 years, numerous percutaneous vascular closure devices have been tested and compared with manual compression and to surgical cut-down. The suture-mediated closure device Perclose ProGlide™ system (Abbott Vascular, CA, USA) emerged as a safe and effective alternative for many procedures requiring either small or large bore vascular accesses. In this review, we will discuss the characteristics of this vascular closure device and the main studies that proved its potential to reduce vascular complications, time to deambulation, time to discharge and patient discomfort.

Accumulation of Ascorbic Acid in Tomato Cell Culture: Influence of the Genotype, Source Explant and Time of In Vitro Cultivation.

The production and commercialization of natural antioxidants is gaining increasing importance due to their wide range of biological effects and applications. In vitro cell culture is a valuable source of plant bioactive compounds, especially those highly dependent on environmental factors. Nonetheless, research on the accumulation in plant cultured cells of water-soluble antioxidant vitamins, such as the ascorbic acid (AsA), is very limited.

Variations of peel essential oils during fruit ripening in four lemon (Citrus limon (L.) Burm. F.) cultivars.

Background: Lemon processing procedures yield a significant amount of waste as peels, which are 57% of processed lemons and represent a possible source of bioactive compounds (essential oils, EOs). EOs were extracted from lemon fruits belonging to four cultivars harvested at four different sampling times (25 October, 23 November, 20 December, 1 February), characterized, and quantified through gas chromatography-mass spectrometry.

Results: The chemical composition of EOs highlighted that 26 compounds of the four lemon cultivars at the different ripening stages were clearly identified.

Characterisation of ground motion recording stations in the Groningen gas field.

The seismic hazard and risk analysis for the onshore Groningen gas field requires information about local soil properties, in particular shear-wave velocity (). A fieldwork campaign was conducted at 18 surface accelerograph stations of the monitoring network. The subsurface in the region consists of unconsolidated sediments and is heterogeneous in composition and properties.

Whole-genome re-sequencing of two Italian tomato landraces reveals sequence variations in genes associated with stress tolerance, fruit quality and long shelf-life traits.

Tomato is a high value crop and the primary model for fleshy fruit development and ripening. Breeding priorities include increased fruit quality, shelf life and tolerance to stresses. To contribute towards this goal, we re-sequenced the genomes of Corbarino (COR) and Lucariello (LUC) landraces, which both possess the traits of plant adaptation to water deficit, prolonged fruit shelf-life and good fruit quality.

Epistatic interaction between MyD88 and TIRAP against Helicobacter pylori.

The genes MyD88 and TIRAP encode the adaptor proteins MyD88 and TIRAP. TIRAP plays the crucial role of activating the MyD88-dependent pathway, which in turn controls the immune response (innate and adaptive) to Helicobacter pylori. We looked for an association of MyD88 and TIRAP with H.

Transcriptome and metabolome of synthetic Solanum autotetraploids reveal key genomic stress events following polyploidization.

Polyploids are generally classified as autopolyploids, derived from a single species, and allopolyploids, arising from interspecific hybridization. The former represent ideal materials with which to study the consequences of genome doubling and ascertain whether there are molecular and functional rules operating following polyploidization events. To investigate whether the effects of autopolyploidization are common to different species, or if species-specific or stochastic events are prevalent, we performed a comprehensive transcriptomic and metabolomic characterization of diploids and autotetraploids of Solanum commersonii and Solanum bulbocastanum.

Evaluation of fruit quality, bioactive compounds and total antioxidant activity of flat peach cultivars.

Background: Fruit quality traits (fresh weight, dry weight, soluble solids content, titratable acidity and firmness) as well as the content of bioactive compounds (phenolic compounds) and total antioxidant activity were evaluated in four commercial cultivars of peach (Greta, Ufo 4, Rome Star and Ufo 6) and four of nectarine (Neve, Planet 1, Maria Carla and Mesembrina) differing in fruit shape (standard or flat) and flesh colour (white or yellow), important cultivars of the Italian and foreign market. The higher fruit organoleptic quality and nutritional profile of flat peach and nectarine cultivars make them candidates for exploiting new market opportunities and the chance to improve profits of farmers.

Results: The results showed that assayed quality parameters differed greatly among cultivars.

Heterozygosity at the A625C polymorphic site of the MyD88 gene is associated with Mycobacterium bovis infection in cattle.

The study demonstrates that in cattle, animals heterozygous at the MyD88 A625C polymorphic marker have a 5-fold reduced risk for active pulmonary tuberculosis (odds ratio [OR] = 0.19; P = 6 × 10(-12)). The reduced risk, however, does not extend to animals with latent pulmonary tuberculosis (OR = 0.

Identification of candidate genes for phenolics accumulation in tomato fruit.

Phenolics are antioxidants present in tomato fruit that confer healthy benefits and exhibit crucial roles for plant metabolism and response to environmental stimuli. An approach based on two genomics platforms was undertaken to identify candidate genes associated to higher phenolics content in tomato fruit. A comparative transcriptomic analysis between the S.

Quantitative trait loci pyramiding for fruit quality traits in tomato.

Fruit quality is a major focus for most conventional and innovative tomato breeding strategies, with particular attention being paid to fruit antioxidant compounds. Tomatoes represent a major contribution to dietary nutrition worldwide and a reservoir of diverse antioxidant molecules. In a previous study, we identified two Solanum pennellii introgression lines (IL7-3 and IL12-4) harbouring quantitative trait loci (QTL) that increase the content of ascorbic acid (AsA), phenols and soluble solids (degrees Brix; °Bx) in tomato fruit.

Comparative transcriptomic profiling of two tomato lines with different ascorbate content in the fruit.

In recent years, interest in tomato breeding for enhanced antioxidant content has increased as medical research has pointed to human health benefits from antioxidant dietary intake. Ascorbate is one of the major antioxidants present in tomato, and little is known about mechanisms governing ascorbate pool size in this fruit. In order to provide further insights into genetic mechanisms controlling ascorbate biosynthesis and accumulation in tomato, we investigated the fruit transcriptome profile of the Solanum pennellii introgression line 10-1 that exhibits a lower fruit ascorbate level than its cultivated parental genotype.

The ascorbic acid content of tomato fruits is associated with the expression of genes involved in pectin degradation.

Background: High levels of ascorbic acid (AsA) in tomato fruits provide health benefits for humans and also play an important role in several aspects of plant life. Although AsA metabolism has been characterized in detail, the genetic mechanisms controlling AsA accumulation in tomatoes are poorly understood. The transcriptional control of AsA levels in fruits can be investigated by combining the advanced genetic and genomic resources currently available for tomato.

Management of nonvalvular atrial fibrillation: a comprehensive approach.

Atrial fibrillation is the most common arrhythmia in clinical practice, may coexist with conditions common to both cardiovascular and noncardiovascular diseases and is associated with considerable morbidity and mortality. Atrial fibrillation is often asymptomatic and diagnosed only when it has caused a potentially serious complication, such as an ischemic stroke. When atrial fibrillation has been identified, 2 objectives have to be addressed--the antiarrhythmic therapy based on rate control or rhythm control, and prevention of thromboembolism.

Antioxidant nutritional quality of tomato.

Regular consumption of tomatoes has been associated with decreased risk of chronic degenerative diseases. Epidemiological findings confirm the observed health effects are due to the presence of different antioxidant molecules such as carotenoids, particularly lycopene, ascorbic acid, vitamin E and phenol compounds, particularly flavonoids. In this work, eight components contributing to the healthy quality of tomato (i.
