Context. White-light flares (WLFs) are crucial for understanding the energy transport and heating processes in the lower solar atmosphere. Systematic studies are highly necessary. However, most WLFs are very weak and dif...

The Neupert effect empirically states that, for many solar flares, the soft X-ray (SXR) time derivative nearly fits the hard X-ray (HXR) or microwave time profiles. This simple relationship supports flare models in which...

High-mass microquasars are binary systems composed by a massive star and a compact object from which relativistic jets are launched. Regarding the companion star, observational evidence supports the idea that winds of ho...

We present a new method for automatic detection of flare events from images in the optical range. The method uses neural networks for pattern recognition and is conceived to be applied to full-disk Halphaimages. Images a...

The almost unexplored frequency window from submillimeter to mid-infrared (mid-IR) may bring new clues about the particle acceleration and transport processes and the atmospheric thermal response during solar flares. Bec...

We present high time resolution observations of Active Region 8910 obtained simultaneously at 212 and 405 GHz during a large Hα flare, which produced a soft X-ray class X1.1 event. Data were obtained with the new solar ...

Abstract Objective To review the existing recommendations on the prenatal care of women with systemic lupus erythematosus (SLE), based on currently available scientific evidence. Methods An integrative review was per...

IntroductionGouty tophi are chronic inflammatory nodules resulting from monosodium urate (MSU) crystal deposition, often leading to joint deformity, skin ulceration, and functional impairment. Surgical management remains...

IntroductionChronic spontaneous urticaria (CSU) is a clinical diagnosis managed according to American Academy of Allergy, Asthma & Immunology (AAAAI) and the American College of Allergy, Asthma & Immunology (ACAAI) guide...

IntroductionMacrophage activation syndrome (MAS) is a rare, potentially fatal hyperinflammatory complication of autoimmune disease, characterized by fever, cytopenias, hyperferritinemia, and multiorgan involvement (1). I...

Context. The physical mechanisms driving neutrino and electromagnetic flares in blazars remain poorly understood. Aims. We investigate a prominent multimessenger flare in the quasar PKS 0446+11 to identify the processes ...

Abstract Objective Pregnancy in women with lupus poses a higher risk of complications compared with the general population. The present study aimed to determine and describe the obstetric and neonatal outcomes of pregna...

BackgroundComplex inflammatory phenotypes in children can pose significant diagnostic challenges, particularly when clinical, histopathologic, and immunologic findings do not conform to established diagnoses. We present ...

Background and Literature ReviewHypereosinophilic syndrome (HES) is a rare, heterogeneous group of disorders defined by persistent hypereosinophilia (>1,500 cells/µL) with eosinophil-mediated end-organ damage. Its estim...

Background Chronic relapsing diseases, such as ulcerative colitis, incur considerable long-term health burden to the patient and the state. Early interventions that reduce the rate of relapse could provide considerable b...

The short-lived active region (AR) NOAA 7968 was thoroughly observed all along its disk transit (June 3 to 10, 1996) from space and from the ground. During the early stage of its evolution, flux emerged in between the tw...

Abstract Background Knee osteoarthritis (KOA) is a prevalent degenerative joint condition marked by progressive loss of articular cartilage and chronic inflammation. Recent studies have recognized Cellular Communication ...

The line-of-sight magnetograms from Solar Optical Telescope Narrowband Filter Imager observations of NOAA Active Region 10930 have been used to study the evolution of spinning and braiding helicities over a period of fiv...

The VHE (E > 100 GeV) blazar Mrk 501 was observed between April 17 and May 5, 2009, as part of a 4.5-months-long multiwavelength campaign from radio to VHE gamma-ray. This source has a history of spectral variability wit...

O experimento foi conduzido por três anos na EPAGRI - Estação Experimental de Ituporanga, SC, com o objetivo de selecionar cultivares de milho e sorgo para ensilagem. Foram testados treze cultivares de milho e oito de...

O experimento foi conduzido na Epagri, Estação Experimental de Ituporanga, SC, com o objetivo de determinar a época e a densidade de semeadura de Avena strigosa Schreb. (aveia preta) e Lolium multiflorum Lam. (azevém...
