Changes in the Antibacterial Performance of Polymer-Based Nanocomposites Induced by Additive Manufacturing Processing.

The idea supporting the investigation of the current manuscript was to develop customized filters for air conditioners with different pore percentages and geometry with the additional advantage of presenting antibacterial performance. This property was expected due to the reinforcement of Cu nanoparticles in the polymeric matrix of poly(lactic acid) (PLA) and polyurethane (TPU). The filaments were characterized by their chemical composition, thermal and mechanical properties, and antibacterial behavior before and after processing by fused filament fabrication.

Cytogenetic markers in newborns of mothers with comorbidities.

We have studied the presence and frequency of micronuclei in exfoliated oral mucosa cells of full-term newborns and their association with maternal prenatal factors. We report an analytical, observational, cross-sectional, prospective study that includes 97 preterm infants (<37 weeks), 37 newborns from mothers with comorbidities, and 60 newborns from mothers without comorbidities, in a tertiary public hospital. Oral mucosa cells were collected within 24 h after birth.

Baclofen modulates the immune response after spinal cord injury with locomotor benefits.

Background And Purpose: Spinal cord injury (SCI) is a neurological condition that affects motor and sensory functions below the injury site. The consequences of SCI are devastating for the patients, and although significant efforts have been done in the last years, there is no effective therapy. Baclofen has emerged in the last few years as an interesting drug in the SCI field.

Nutritional Deficiencies Before and After Metabolic and Bariatric Surgery in Patients Above 50.0 kg/m: A Single Center Study.

Purpose: Metabolic and bariatric surgery (MBS) is an effective treatment for patients with body mass index (BMI) above 50.0 kg/m but nutritional deficiencies (ND) may arise. This study aimed to assess if patients with BMI above 50.

Pesticides and violations of human rights to health and food sovereignty in Guarani Kaiowá communities in MS, Brazil.

Brazil, one of the world's largest agricultural producers and consumers of pesticides, has expanded its agricultural area in the southern region of Mato Grosso do Sul, intensifying environmental contamination and increasing the vulnerability of indigenous populations. This research assessed the presence of pesticides in the waters of two indigenous communities in MS, Retomada Guyraroká and Aldeia Jaguapiru. Between 2021 and 2022, three sampling campaigns of surface, supply, and rainwater were conducted, considering the agricultural calendar.
