Objective: To record in detail, the long-term success of a bleaching treatment employing hydrogen peroxide in a severely darkened tooth.
Clinical Considerations: Tooth discoloration is an important aesthetic complain of patients. Because it is a relatively common condition, different materials and techniques capable of restoring the tooth color in a minimally invasive, conservative, and longstanding manner were developed. In this case, it was used the association between mediate (walking bleach) and immediate (internal/external) bleaching techniques using hydrogen peroxide as the main agent.
Conclusion: The association of techniques was a conservative therapeutic solution to restore the natural color of the right upper central incisor, which was darkened after an endodontic treatment performed more than twenty years ago. The bleaching protocol used presented no risk to the patient, such as cervical resorption and the color was stable over a 48 months period, showing the success of the protocol proposed for this case.
Clinical Significance: There is a possibility to severely darkened teeth receive an adequate bleaching treatment protocol, which can successfully restore the aesthetics and natural color in a conservative and long lasting way.

Blackberry can be considered a source of phenolic compounds with antioxidant properties, especially anthocyanins, which are responsible for the attractive color of the juice. However, blackberry juice quality can be reduced under severe heat treatments, resulting in darkened color and altered taste. Membrane separation processes are an alternative for the clarification and concentration of fruit juices, with advantages as the maintenance of the nutritional, sensory, and functional characteristics of the product.

The Ralstonia solanacearum Species Complex (RSSC) is the most significant plant pathogen group with a wide host range. It is genetically related but displays distinct biological features, such as restrictive geography occurrence. The RSSC comprises three species: Ralstonia pseudosolanacearum (phylotype I and III), Ralstonia solanacearum (phylotype IIA and IIB), and Ralstonia syzygii (phylotype IV) (Fegan and Prior 2005).

Background: We evaluated the inhaled corticosteroid/long-acting muscarinic antagonist/long-acting β-agonist (ICS/LAMA/LABA) triple therapy with budesonide/glycopyrronium/formoterol fumarate dihydrate (BGF) versus dual LAMA/LABA and ICS/LABA therapies in patients with chronic obstructive pulmonary disease (COPD) and phenotypic features of asthma (bronchodilator reversibility and elevated blood eosinophils), but no asthma diagnosis, for whom treatment guidelines are limited.
Patients And Methods: KRONOS (NCT02497001) and ETHOS (NCT02465567) enrolled patients with moderate-to-very-severe COPD, no current asthma diagnosis, and either ≥0 (KRONOS) or ≥1 (ETHOS) moderate/severe exacerbations in the prior year. This pooled post hoc analysis evaluated trough forced expiratory volume in 1 second (FEV) and FEV area under the curve from hours 0 to 4 (AUC) change from baseline over 12-24 weeks, moderate/severe exacerbation rates, and St George's Respiratory Questionnaire (SGRQ) total score over 24 weeks with ICS/LAMA/LABA (BGF 320/14.

Ginger, as a globally vital medicinal and food homologous crop, plays an irreplaceable role in human diet and healthcare. However, during the storage of ginger, the decline of physical properties and degradation of volatile flavor quality have emerged as an industrial concern that severely restricts the market value of the product. MeJA plays an essential role in extending fruit shelf life and regulate the synthesis of volatiles in horticultural products, yet its application in ginger remains unreported.

is a diverse genus of evergreen and deciduous species grown in gardens worldwide for their attractive flowers and foliage. In summer 2023, nine of 12 potted 'Nova Zembla' plants purchased from a wholesale nursery in Ohio exhibited wilting, leaf and stem discoloration, and severely darkened and softened roots, which eventually progressed into dieback and plant death. Roots tested positive with a Phytophthora Immunostrip® (Agdia, Inc.
