13. Consensus on the therapeutic management of atopic dermatitis - Brazilian Society of Dermatology
Abstract: BACKGROUND: Atopic dermatitis is a highly prevalent inflammatory and pruritic dermatosis with a multifactorial etiology, which includes skin barrier defects, immune dysfunction, and microbiome alterations. Atopic dermatitis is mediated by genetic, environmental, and psychological factors and requires therapeutic management that covers all the aspe

15. Avaliação química, ecotoxicológica e genotoxicológica de águas de cavas de mineração a céu aberto
RESUMO Lagos artificiais formados em áreas de mineração a céu aberto são unidades complexas e se constituem em passivos ambientais emergentes advindos da indústria da mineração. Embora estejam aumentando em número em várias partes do globo, são um problema ambiental recente e ainda pouco estudado, especialmente no tocante à qualidade e à toxicid

16. Behavioral, affective, and cognitive alterations induced by individual and combined environmental stressors in rats
Objective: To evaluate whether exposing rats to individual or combined environmental stressors triggers endophenotypes related to mood and anxiety disorders, and whether this effect depends on the nature of the behavior (i.e., innate or learned). Methods: We conducted a three-phase experimental protocol. In phase I (baseline), animals subjected to mixed sc

17. Study of skin neoplasms in a university hospital: integration of anatomopathological records and its interface with the literature
Abstract: Background: Skin cancer is a highly prevalent condition with a multifactorial etiology resulting from genetic alterations, environmental and lifestyle factors. In Brazil, among all malignant tumors, skin cancers have the highest incidences. Objective: To retrospectively evaluate the incidence, prevalence and profile of basal cell carcinoma, squam

18. Characterization of different techniques for obtaining minced fish from tilapia waste
Abstract The majority of tilapia farming is used for the production of fillets, resulting in the generation of waste that can be used to increase food stocks by producing minced fish. The aim of this study was to characterize and evaluate the viability of boiling and mechanical techniques for obtaining minced fish in relation to performance, physical-chemic

19. Hypnea musciformis (Wulfen) J. V. Lamour. (Gigartinales, Rhodophyta) responses to gasoline short-term exposure: biochemical and cellular alterations
ABSTRACT Presence of toxic compounds in marine coastal waters has increased exponentially since Industrial Revolution. In this way, we aimed to evaluate biochemical and physiological changes occurring within Hypnea musciformis after short-term exposure to gasoline. Hypnea musciformis was cultivated without gasoline and then exposed to various concentrations

20. Surface and vertical dimensional changes of mineral trioxide aggregate and biodentine in different environmental conditions
Abstract Surface changes in biological environments are critical for the evaluation of physical and biological activity of biomaterials. Objective: This study investigated surface alterations of calcium silicate-based cements after exposure to different environments. Material and Methods: Forty-eight cylindrical cavities were prepared on root surfaces. The c

21. Soil organic matter fractions affected by N-fertilizer in a green cane management in Brazilian Coastal Tableland
ABSTRACT The recent approach of eliminating the use of fire for sugarcane harvesting (green cane) resulted in managing the crop on a trash-blanketed soil, which changed the content and dynamic of carbon and the nitrogen requirement. These alterations are relevant due to economic and environmental aspects of sugarcane production systems. This study aimed to e

22. Temporal assessment of microbial communities in soils of two contrasting mangroves
ABSTRACT Variations in microbial communities promoted by alterations in environmental conditions are reflected in similarities/differences both at taxonomic and functional levels. Here we used a natural gradient within mangroves from seashore to upland, to contrast the natural variability in bacteria, cyanobacteria and diazotroph assemblages in a pristine ar

23. Influence of substrate on the richness and composition of Neotropical cave fauna
ABSTRACT The food base in the subterranean environment consists mainly of allochthonous materials. In this environment the resources are distributed generally in a heterogeneous dispersed way and the distribution of resources and their availability determine where the terrestrial invertebrates will reside, which is important for understanding ecological rela

24. Aryl hydrocarbon receptor overexpression in miniaturized follicles in female pattern hair loss
Abstract The etiopathogenesis of female pattern hair loss is still poorly understood. In addition to genetic and hormonal elements, environmental factors could be involved. The aryl hydrocarbon receptor is expressed in keratinocytes and can be activated by environmental pollutants leading to alterations in the cell cycle, inflammation, and apoptosis. Here we
