Enhanced degradation and removal of ciprofloxacin and ofloxacin through advanced oxidation and adsorption processes using environmentally friendly modified carbon nanotubes.

This study explores the utilization of adsorption and advanced oxidation processes for the degradation of ofloxacin (OFL) and ciprofloxacin (CIP) using a green functionalized carbon nanotube (MWCNT-OH/COOH-E) as adsorbent and catalyst material. The stability and catalytic activity of the solid material were proved by FT-IR and TG/DTG, which also helped to elucidate the reaction mechanisms. In adsorption kinetic studies, both antibiotics showed similar behavior, with an equilibrium at 30 min and 60% removal. The adsorption kinetic data of both antibiotics were well described by the pseudo-first-order (PFO) model. Different advanced oxidation processes (AOPs) were used, and the photolytic degradation was not satisfactory, whereas heterogeneous photocatalysis showed high degradation (⁓ 70%), both processes with 30 min of reaction. Nevertheless, ozonation and catalytic ozonation have resulted in the highest efficiencies, 90%, and 70%, respectively, after 30-min reaction. For AOP data modeling, the first-order model better described CIP and OFL in photocatalytic and ozonation process. Intermediates were detected by MS-MS analysis, such as P313, P330, and P277 for ciprofloxacin and P391 and P332 for ofloxacin. The toxicity test demonstrated that a lower acute toxicity was observed for the photocatalysis method samples, with only 3.1 and 1.5 TU for CIP and OFL, respectively, thus being a promising method for its degradation, due to its lower risk of inducing the proliferation of bacterial resistance in an aquatic environment. Ultimately, the analysis of MWCNT reusability showed good performance for 2 cycles and regeneration of MWCNT with ozone confirmed its effectiveness up to 3 cycles.

Propranolol adsorption onto multiwalled carbon nanotubes modified by green synthesis: pH, kinetic, and equilibrium studies.

This research investigated the adsorption of propranolol (PROP) by functionalized green carbon nanotubes (MWCNT-B), assessing the influence of pH, in addition to kinetic, equilibrium, and thermodynamic studies and reuse of the material. For this purpose, speciation of PROP and the point of zero charge (pHPZC) of MWCNT-B were performed, indicating a pKa of 9.67 and pHPZC of 3.31. The adsorption tests at different pH values revealed that in the range of pH 3 to 9, there is no significant variation in PROP uptake, despite this, at pH 11, the removal decreases. Regarding PROP adsorption, the equilibrium time ranged from 30 to 90 min, and the PFO model best represented the kinetic data. The Langmuir model was more predictive in representing isotherms (R2 > 0.95), and the adsorption process was spontaneous and favorable (ΔG < - 20 kJ mol-1) and indicated exothermic behavior (ΔH = - 33 kJ mol-1) for PROP removal. In addition, the material showed satisfactory thermal regeneration results and can be reused for four cycles. The results suggest that MWCNT-B is an attractive adsorbent and exhibits effective removal of propranolol from aqueous matrices.

Viral Hepatitis A, B and C in a Group of Transgender Women in Central Brazil.

Transgender women (TGW) have limited access to affordable viral hepatitis testing, hepatitis B vaccination, and treatment. We aimed to estimate the prevalence of viral hepatitis A, B, and C, as well as to compare the adherence and immunogenicity of two hepatitis B vaccine schedules among TGW in Central Brazil. A total of 440 TGW were interviewed and tested for hepatitis A, B, and C serological markers from 2017 to 2018. The hepatitis B vaccine was offered to 230 eligible TGW: 112 received a super accelerated hepatitis B vaccine schedule (G1) and 118 a standard schedule (G2). The antibody against the hepatitis A virus (HAV) was detected in 75.63% of the participants, and 12.3% of the TGW were exposed to the hepatitis B virus (HBV). Two (0.46%) participants were HBV carriers. Only 41.5% of the participants showed a serological profile of hepatitis B vaccination. The antibody against the hepatitis C virus (anti-HCV) was found in six participants (1.37%). Of the TGW who received the first vaccine dose, 62 (55.36%) and 49 (41.52%) in G1 and G2, respectively, received three doses (p = 0.036). The vaccine response was evaluated in 28 G1 and 22 G2 TGW; of these, 89.3% and 100% developed protective anti-hepatitis B surface-antigen titers, respectively (p = 0.113). Since one-third of younger transgender women are susceptible to HAV, hepatitis B immunization is low, and the anti-HCV rate is higher in this group than in the general population in Central Brazil, public-health attention is warranted. The super-accelerated scheme demonstrated better adhesion and good immunogenicity, suggesting that it would be a more cost-effective solution.

Análise midiática sobre o futebol feminino no Brasil: elementos didáticos para a Educação Física no ensino médio / Media analysis on women's soccer in Brazil: didactic elements for Physical Education in high school / Análisis mediático sobre fútbol femenino en Brasil: elementos didácticos para la Educación Física en la escuela secundaria

O objetivo desse estudo foi compreender a produção discursiva da revista PLACAR sobre o futebol feminino no Brasil e, após essa análise, produzir conhecimentos que possam ser utilizados para fomentar o debate sobre as relações de gênero nas práticas corporais durante as aulas de Educação Física no Ensino Médio. A partir de uma pesquisa documental, em 1017 periódicos da revista PLACAR, localizados na biblioteca do Museu do Futebol em São Paulo, foi realizada a análise de conteúdo para identificar as unidades de significado produzidas sobre o futebol feminino. A produção discursiva sobre a mulher no futebol está fortemente marcada pela proibição e discriminação em seu passado. Apesar disso, graças a inúmeras atletas e aos ideais feministas, as jogadoras estão gradativamente conseguindo espaço e respeito. Esse debate pode ser fomentado nas aulas de Educação Física Escolar a partir dos resultados dessa pesquisa.

The objective of this study was to understand the discursive production of PLACAR magazine on women's football in Brazil and, after this analysis, to produce knowledge that can be used to foster the debate on gender relations in body practices during Physical Education in High School. Based on a documentary research, in 1017 periodicals of PLACAR magazine, located in the library of the Museum of Football in São Paulo, a content analysis was carried out to identify the units of meaning produced about women's football. Discursive production about women in football is strongly marked by prohibition and discrimination in their past. Despite this, thanks to countless athletes and feminist ideals, the players are gradually gaining space and respect. This debate can be fostered in Physical Education classes from the results of this research.

Conservation potential of shade-tolerant forest species in agricultural mosaics in the eastern Brazilian Amazon

Shade-tolerant forest species are among the most susceptible to habitat loss in agricultural mosaics, where a variety of croplands is connected to forests at different levels of anthropogenic disturbance. We aimed to evaluate the community similarity of shade-tolerant species among different land use types across agricultural mosaics with different levels of disturbance. The study was conducted in three municipalities in southern and southeastern Pará state, in eastern Amazonia. A multiple-community similarity measure based on the Horn similarity index was used to compare land use types and assess the resilience of shade-tolerant species towards forest loss and disturbance at the landscape level. High shade-tolerant species similarity was found between mature forest fragments that underwent different levels of disturbance in all three agricultural mosaics, but secondary forests had lower similarity with mature forest in the most fragmented and altered mosaic. Shade-tolerant species showed very low density in croplands, but the same group of species seemed to colonize agricultural fields of annual crops and clean pasture, as they showed high community similarity. Another group of species was present in invaded pastures, probably due to the effects of time since land abandonment after woody species colonization. Mixed tree plantations were more similar to mature and secondary forests than other types of croplands. Shade-tolerant species similarity was higher among land use types inserted in agricultural landscapes that maintained conserved forest fragments. Our results suggest that the conservation of mature forests and landscape connectivity are crucial to the maintenance of shade-tolerant species in agricultural mosaics. (AU)

Objective: To report the experience of healthcare professionalsin the development of an educational resource to enhancehealth education actions on smoking in schools. ExperienceReport: The educational resource was created in 2012 by tworesidents of a specialization course in the MultidisciplinaryResidency in Family Health, Alagoas State University of HealthSciences. The educational resource consists of a doll called“Fumazete”, which shows the signs and symptoms of a smoker;through the senses and ego states this doll demonstrates thechanges in the smoking process. The resource is also composedby a wall, which has the trachea and lungs format anddemonstrates by means of figures some components ofcigarettes as well as the consequences of smoking. The childreninteracted with the doll and so knew the consequences ofsmoking, as well as the importance of supporting and guidingthose who decide to abandon such dependence. Comments:Working with the doll was a guiding strategy that used the ludicand ego states to cause a different feeling in each person. Bydoing so, the individuals would reframe a moment of theirlives that will be remembered due to the characteristicscontained either in the doll or in the wall. Thus, this resourceallows the students to learn about smoking and as well as tolink this topic with their own life experiences and, as such, actas multipliers of knowledge to prevent the use of tobacco. Theuse of the educational resource “Fumazete “ contributes to therethinking of strategies that are conceived in the interactionbetween schools and health services and the community,providing a more effective and humane background...
