Prevalence of genetic variants in SERPINB2 and PKNOX1 genes in erythema nodosum leprosum patients from southern Brazil.

Introduction: Erythema nodosum leprosum (ENL) is a humoral immune response to Mycobacterium leprae that is characterized by erythematous nodules, and may or may not be associated with systemic symptoms. Thalidomide is the primary treatment for ENL in Brazil, but peripheral neuropathy (PN) is a significant adverse effect. Genetic variants in SERPINB2 and PKNOX1 genes have been implicated in the predisposition to develop thalidomide-induced peripheral neuropathy (TiPN) in patients with multiple myeloma.

Sensitizing agents found in children and adolescents with recalcitrant atopic dermatitis: a cross-sectional study with a pediatric battery.

Background: Atopic dermatitis is the most common inflammatory skin disease in childhood and has an important impact on quality of life, especially severe cases or those that are recalcitrant to treatments. Sensitization to allergens with the potential for allergic contact dermatitis is a factor associated with cases of recalcitrant atopic dermatitis. Understanding the relationship between atopic dermatitis, allergens, and allergic contact dermatitis is essential.

Tumor in the plantar region: dermatofibrosarcoma protuberans in an infrequent topography.

Dermatofibrosarcoma protuberans is a rare mesenchymal tumor; it is locally aggressive and presents high rates of local recurrence. It may present as a nodular or plaque vegetating lesion. It mainly affects the trunk and proximal limbs, being rare in the distal extremities.

Anoxic-biocathode microbial desalination cell as a new approach for wastewater remediation and clean water production.

Bioelectrochemical systems are emerging as a promising and friendly alternative to convert the energy stored in wastewater directly into electricity by microorganisms and utilize it in situ to drive desalination. To better understand such processes, we propose the development of an anoxic biocathode microbial desalination Cell for the conversion of carbon- and nitrogen-rich wastewaters into bioenergy and to perform salt removal. Our results demonstrate a power output of 0.

Prospects in bioelectrochemical technologies for wastewater treatment.

Bioelectrochemical technologies are emerging as innovative solutions for waste treatment, offering flexible platforms for both oxidation and reduction reaction processes. A great variety of applications have been developed by utilizing the energy produced in bioelectrochemical systems, such as direct electric power generation, chemical production or water desalination. This manuscript provides a literature review on the prospects in bioelectrochemical technologies for wastewater treatment, including organic, nutrients and metals removal, production of chemical compounds and desalination.

Biological fuel cells produce bioelectricity with in-situ brackish water purification.

Biological fuel cells, namely microbial desalination cells (MDCs) are a promising alternative to traditional desalination technologies, as microorganisms can convert the energy stored in wastewater directly into electricity and utilize it in situ to drive desalination, producing a high-quality reuse water. However, there are several challenges to be overcome in order to scale up from laboratory research. This study was conducted in order to better understand the performance of MDCs inoculated with marine sediments during the treatment of brackish water (5.

Inhibition of an enriched culture of ammonia oxidizing bacteria by two different nanoparticles: Silver and magnetite.

Metal and metal oxide nanoparticles are getting attention over the past years. They can be used to several purposes, especially in commercial and medical applications. Undoubtedly, this lead to higher production and, consequently, increasing the risks of exposition, once they can be released into environment without a proper control.

Magnetite nanoparticles influence the ammonium-oxidizing bacteria activity during nitritation process.

With nanotechnology dissemination, nanomaterials' (NMs) release into the environment is inevitable and may adversely affect the wastewater treatment processes. Among the NMs, the iron oxide nanoparticles have a considerable commercial potential, mainly because their magnetic properties, high catalytic ability and antimicrobial activity. However, few studies have examined their potential effect on the biological wastewater treatment.
