Abundant but short second-generation sequencing reads make assembly difficult, leading to fragmented genomes and gene annotations. Gene structure information from RNA sequences can be used to improve the completeness and contiguity of an assembly, but bioinformatics methods have been lacking. Rascaf is a highly efficient tool leveraging long-range continuity information from intron spanning RNA sequencing (RNA-seq) read pairs to detect new contig connections. It determines a heaviest path in an exon block graph that simultaneously represents a gene and the underlying contig relationships...

BACKGROUND: Laser and light-based therapies have been used successfully in the treatment of rosacea; however, evidence is lacking regarding the efficacy of radiofrequency (RF). OBJECTIVE: This study evaluated the efficacy of RF in the treatment of rosacea compared with pulsed dye laser (PDL). METHODS: Thirty patients with rosacea (erythematotelangiectatic rosacea [ETR], n = 20; papulopustular rosacea [PPR], n = 10) were enrolled in a randomized, controlled, split-face study...

Infestation by the biotrophic pathogen Gymnosporangium asiaticum can be devastating for plant of the family Rosaceae. However, the phytopathology of this process has not been thoroughly elucidated. Using a metabolomics approach, we discovered the intrinsic activities that induce disease symptoms after fungal invasion in terms of microbe-induced metabolic responses. Through metabolic pathway enrichment and mapping, we found that the host altered its metabolite levels, resulting in accumulation of tetrose and pentose sugar alcohols, in response to this fungus...

Antimicrobial peptides are central effector molecules in skin immunology. The functions of antimicrobial peptides in skin diseases include the ability to act as cytokines or growth factors, driving disorders such as psoriasis and rosacea, as well as their action as natural antibiotics to control bacteria that influence diseases such as atopic dermatitis and acne.

BACKGROUND: Minocycline, a broad-spectrum antibiotic from the group of tetracyclins, is frequently prescribed for acne vulgaris and rosacea. Hyperpigmentation is a relatively common side effect of this drug and can lead to multiple unsightly skin lesions, which are not always reversible. It can take a long period, from a few months to several years, before the lesions have completely vanished. CASE DESCRIPTION: A 24-year-old male was seen in our outpatient clinic because of slowly progressive pigmented lesions on his shins...

FT gene is expressed in leaves and buds and is involved in floral meristem determination and bud development in sweet cherry. In woody fruit perennial trees, floral determination, dormancy and bloom, depends on perception of different environmental and endogenous cues which converge to a systemic signaling gene known as FLOWERING LOCUS T (FT). In long-day flowering plants, FT is expressed in the leaves on long days. The protein travels through the phloem to the shoot apical meristem, where it induces flower determination...

Patient-reported treatment outcomes are important for evaluating the impact of drug therapies on patient experience. A randomized, double-blind, vehicle-controlled, parallel-group, multicenter, phase 3 study was conducted in 961 participants to assess patient perception of efficacy, utility, and effect on quality of life (QOL) of an azelaic acid (AzA) 15% foam formulation for the treatment of papulopustular rosacea (PPR). Secondary end points included patient-reported global assessment of treatment response, global assessment of tolerability, and opinion on cosmetic acceptability and practicability of product use...

Although there is presently no cure for rosacea, there are several recommended treatment options available to control many of the symptoms and to prevent them from getting worse. In addition to self-help measures like avoidance of trigger factors and proper skin care, rosacea management should include topical medications as one of the first-line choices for patients with erythematous and mild to severe papulopustular rosacea. Since mixed forms of characteristic rosacea symptoms are more common, medical treatment must be symptom-tailored for each individual case and will often involve a combination therapy...

Rosazea ist eine häufige chronisch-entzündliche Hauterkrankung, die typischerweise bei Erwachsenen vorkommt und das Gesicht betrifft. Synonyme der Rosazea sind Acne rosacea, Kupferfinne, Rotfinne, Couperose und Rosacea. Die Erkrankung ist durch einen chronischen und schubartigen Verlauf gekennzeichnet und wird durch ein genetisch prädisponiertes, multifaktorielles Geschehen bedingt. Ein vermehrtes Auftreten wird bei hellem Hauttyp und positiver Familienanamnese verzeichnet. Die charakteristischen Rosazea-Symptome manifestieren sich vorwiegend, aber nicht ausschließlich zentrofazial, wobei Stirn, Nase, Kinn und die Wangen maßgeblich betroffen sind...

Rosacea is characterised by a wide variety of vascular changes. Apart from telangiectasia and erythema, often so-called flushing occurs. These vascular abnormalities can be targeted with specific light and laser devices. In addition to KTP laser, pulsed dye laser (PDL) and Nd:YAG laser, also intense pulsed light devices (IPLs) are used. The described therapeutic effects include the reduction of vascular abnormalities and even improvement of papulopustular changes. While the KTP laser shows very good results in telangiectasia, the dye laser and IPL devices are used preferably in erythema...

Based on numerous trials, oral tetracyclines and most commonly their second-generation derivative doxycycline have become the main pillar in systemic rosacea treatment. However, the only preparation that has been approved so far in this setting is 40 mg doxycycline in an anti-inflammatory dosage and with a modified release formulation. With the introduction of this once-daily, non-antibiotic dosing of doxycycline, oral therapy is more commonly prescribed as first-line treatment in moderate to severe papulopustular rosacea...

Rosacea is a common chronic inflammatory skin disorder that typically occurs in adults and affects the face. Synonyms of rosacea include "acne rosacea", "couperose" and "facial erythrosis", in German also "Kupferfinne" and "Rotfinne". The disorder is characterised by a chronic and flaring course and is caused by a genetically predisposed, multifactorial process. A higher incidence is seen in people with fair skin and a positive family history. The characteristic rosacea symptoms manifest primarily, but not exclusively centrofacially, with forehead, nose, chin and cheeks significantly affected...

BACKGROUND: Rosacea is currently treated according to subtypes. As this does not adequately address the patient spectrum of clinical presentation (phenotypes), it has implications for patient management. The ROSacea COnsensus (ROSCO) panel was established to address this issue. OBJECTIVES: To incorporate current best treatment evidence with clinical experience from an international expert panel and establish consensus to improve outcomes for patients with rosacea...

Fruits are the defining feature of angiosperms, likely have contributed to angiosperm successes by protecting and dispersing seeds, and provide foods to humans and other animals, with many morphological types and important ecological and agricultural implications. Rosaceae is a family with ~3000 species and an extraordinary spectrum of distinct fruits, including fleshy peach, apple, and strawberry prized by their consumers, as well as dry achenetum and follicetum with features facilitating seed dispersal, excellent for studying fruit evolution...

REVIEW
Manal Abokwidir, Steven R Feldman
BACKGROUND: Rosacea is a chronic inflammatory skin condition associated with four distinct subtypes: erythematotelangiectatic, papulopustular, phymatous, and ocular. PURPOSE: To review the different kinds of management for all subtypes. METHODS: We divided rosacea management into three main categories: patient education, skin care, and pharmacological/procedural interventions. RESULTS: Flushing is better prevented rather than treated, by avoiding specific triggers, decreasing transepidermal water loss by moisturizers, and blocking ultraviolet light...

Studying closely related species and divergent populations provides insight into the process of speciation. Previous studies showed that the Sibiraea complex's evolutionary history on the Qinghai-Tibetan Plateau (QTP) was confusing and could not be distinguishable on the molecular level. In this study, the genetic structure and gene flow of Sibiraea laevigata and Sibiraea angustata on the QTP was examined across 45 populations using 8 microsatellite loci. Microsatellites revealed high genetic diversity in Sibiraea populations...

Peach (Prunus persica L.) is a highly valuable crop species and is recognized by molecular researchers as a model fruit for the Rosaceae family. Using whole-genome sequencing data generated from 129 peach accessions, here we perform a comprehensive genome-wide association study for 12 key agronomic traits. We show that among the 10 qualitative traits investigated, nine exhibit consistent and more precise association signals than previously identified by linkage analysis. For two of the qualitative traits, we describe candidate genes, one potentially involved in cell death and another predicted to encode an auxin-efflux carrier, that are highly associated with fruit shape and non-acidity, respectively...
