Parthenolide (PTN) is a secondary metabolite of the plant Tanacetum parthenium (L.) Schulz Bip. and is considered the chemical marker of this species. This sesquiterpene lactone (germacrene skeleton) has been described as responsible for the biological activity of the leaf extract. In addition, several studies in the literature have demonstrated its antiparasitic and antineoplastic activity. However, there is a need for knowledge of other safety parameters, such as pharmacokinetic, pharmacodynamic and toxicity evaluations. Therefore, in this investigation, the in vitro metabolism of parthenolide was performed with rat liver microsomes and biomimetic metabolism (such as cytochrome P-450 system) using organometallic catalysts. The biomimetic procedure was validated since the major compound of biomimetic oxidative reaction with meta-chloroperbenzoic acid catalyzed by metalloporphyrin 5,10,15,20-tetrakis(pentafluorophenyl)-porphyrin iron(III) chloride was also observed with rat liver microsomes. Previous chemoenzymatic synthesis studies of PTN afforded the same epoxide formation, this major oxidative compound was isolated and fully characterized as (1 R,10R)-epoxyparthenolide based on experimental and theoretical calculations of infrared (IR) and vibrational circular dichroism (VCD) data at the B3PW91/6-311G. Furthermore, for the first time, this metabolite was evaluated for trypanocidal and leishmanicidal activity. The mean inhibitory concentration (IC50) values were lower for PTN than its metabolite and showed significant cytotoxic effects for both parasites. This finding holds promise for addressing neglected diseases. (PTN L. L (L.

Resumo O acúmulo de produtos finais de glicação avançada (AGEs, do inglês advanced glycation end-products) provoca comprometimento morfofuncional dos rins. Os níveis de AGEs podem ser estimados de forma não invasiva por autofluorescência da pele (sAF). Exploramos se a sAF elevada prediz desfechos renais em indivíduos com diabetes tipo 2 (DT2). O estudo foi realizado como uma análise predefinida do Estudo Brasileiro sobre Diabetes, uma coorte prospectiva de centro único de adultos com DT2. Foram considerados os dados de 155 indivíduos acompanhados por até 1.716 dias. A incidência de eventos renais adversos maiores (MAKE, por sua sigla em inglês) foi de 9,6%. Indivíduos com sAF acima da mediana apresentaram maior incidência de MAKEs (4,6% vs. 21%; p = 0,002), com HR de 3,39 [IC 95%: 1,06–10,85; p = 0,040] após ajuste por idade e sexo. A alteração média da TFGe ajustada foi de 1,08 unidades (EP: 1,15; IC95%: –1,20, 3,37) no grupo de baixa sAF e de –5,19 unidades [EP: 1,93; IC95%: –9,10, –1,29] no grupo de elevada sAF (diferença entre sujeitos: F: 5,62; p = 0,019). O grupo sAF elevada apresentou maior prevalência de declínio rápido em comparação ao grupo sAF baixa (36,7% vs. 15,8%; p = 0,028). Em conclusão, a sAF elevada foi relacionada ao aumento da incidência de MAKEs e ao declínio mais rápido da TFGe entre indivíduos com DT2. Tal fato deve ser considerado pelos profissionais de saúde ao identificar indivíduos mais propensos a complicações renais relacionadas ao diabetes.

Abstract The accumulation of advanced glycation end-products (AGEs) elicits morphofunctional kidney impairment. AGEs levels can be noninvasively estimated by skin autofluorescence (SAF). We explored whether high SAF predicts kidney outcomes in type 2 diabetes (T2D) individuals. The study was conducted as a predefined analysis of the Brazilian Diabetes Study, a prospective single-center cohort of T2D adults. Data from 155 individuals followed for up to 1716 days were considered. The incidence of major adverse kidney events (MAKE) was 9.6%. Individuals with above-median SAF had a higher incidence of MAKEs (4.6% vs. 21%; p = 0.002), with an HR of 3.39 [95% CI: 1.06–10.85; p = 0.040] after adjustment by age and gender. The mean adjusted eGFR change was 1.08 units (SE: 1.15; 95%CI: –1.20, 3.37) in the low SAF and –5.19 units [SE: 1.93; 95%CI: –9.10, –1.29] in the high SAF groups (between-subject difference: F: 5.62, p = 0.019). The high-SAF group had a greater prevalence of rapid decliners than the low-SAF group (36.7% vs. 15.8%; p = 0.028). In conclusion, high SAF was related to increased incidence of MAKEs and faster decline in eGFR among T2D subjects.

Nos últimos anos, evidências do Registro Brasileiro de Biópsia óssea (REBRABO) apontaram uma alta incidência de intoxicação por alumínio (Al) no tecido ósseo de pacientes com DRC em diálise. Essa surpreendente informação parece representar não apenas um acúmulo passivo deste metal, visto que dados prospectivos do REBRABO sugerem que a presença de Al no tecido ósseo pode estar independentemente relacionada a eventos cardiovasculares adversos maiores. Essas informações contrastam com a percepção mundial do controle epidemiológico dessa condição. Neste artigo de opinião, discutimos por que o diagnóstico de acúmulo ósseo de Al não é relatado em outras partes do mundo, e também discutimos uma gama de possibilidades para entender por que nós acreditamos que o acúmulo de Al no tecido ósseo ainda ocorre, não como se apresentava no passado, ou seja, como uma síndrome com sinais e sintomas sistêmicos de intoxicação. anos (REBRABO (Al diálise metal maiores condição opinião mundo ocorre passado seja

In the last few years, evidence from the Brazilian Registry of Bone Biopsy (REBRABO) has pointed out a high incidence of aluminum (Al) accumulation in the bones of patients with CKD under dialysis. This surprising finding does not appear to be merely a passive metal accumulation, as prospective data from REBRABO suggest that the presence of Al in bone may be independently associated with major adverse cardiovascular events. This information contrasts with the perception of epidemiologic control of this condition around the world. In this opinion paper, we discussed why the diagnosis of Al accumulation in bone is not reported in other parts of the world. We also discuss a range of possibilities to understand why bone Al accumulation still occurs, not as a classical syndrome with systemic signs of intoxication, as occurred it has in the past. years (REBRABO (Al dialysis events world paper occurs intoxication past

In this study, we describe a light-driven photocatalytic decarboxylation of palmitic acid and related fatty acids using Chlorella variabilis fatty acid photodecarboxylase (CvFAP). By utilizing violet light emitting diode (LED) light (50 W; 397 nm), we achieved a remarkable conversion efficiency of 99% within just 4 min, surpassing the previous 79% conversion achieved in 60 min using blue LED light (300 W; 439 nm). Importantly, the use of 50 W violet LED light also resulted in a lower enzyme photoinactivation rate when compared to 300 W blue LED. Comparing the whole-cell biocatalyst with the enzymatic extract, we found that the former demonstrated superior catalytic performance and reduced susceptibility to photoinactivation. Furthermore, whole-cell biocatalyst reuse was demonstrated after five sequential batches. Employing this approach, we successfully synthesized 26 mmol L-1 h-1 of pentadecane, showcasing a promising strategy to improve productivity. These findings represent a significant advancement in CvFAP photodecarboxylation processes compared to the literature, utilizing an alternative light source, with potential implications to the biofuel sector. study lightdriven driven CvFAP. .

Niobium pentoxide shows an interesting reactivity that allows the control of different aspects of its morphology and chemistry. In this study, Nb2O5 nanoparticles were modified with protoporphyrin IX (PPIX) and tris(ethynylphenyl) pyrene derivative (PyPh3) by using 3-aminopropyltriethoxysilane as linkage group and used as photosensitizers against lung cancer. The antitumor photoactivity against the A549 tumor cell line as a model of in vitro study showed half maximal inhibitory concentration (IC50) ca. 15 μmol L-1 for both materials and the absence of dark activity, indicating the viability of dye-modified Nb2O5 as a photodynamic therapy (PDT) agent. chemistry NbO Nb O Nb2O PPIX (PPIX trisethynylphenyl tris ethynylphenyl tris(ethynylphenyl PyPh3 PyPh (PyPh3 3aminopropyltriethoxysilane aminopropyltriethoxysilane 3 cancer A A54 IC50 IC (IC50 ca 1 L1 L L- activity dyemodified dye PDT (PDT agent (PyPh A5 IC5 (IC5 (IC

Resumo O objetivo é avaliar o efeito de diferentes tratamentos superficiais e do envelhecimento na resistência ao cisalhamento da zircônia ultratranslúcida. Foram confeccionados 36 blocos de zircônia ultratranslúcida (7x7x2mm) e sinterizados. Em seguida, divididos em 12 grupos de acordo com o “tratamento de superfície” (C-Primer; Al-Jateamento com Al2O3+Primer; Si-Silicato+Primer; Gl -Glaze+HF+Primer; Z-Zirlink; Zp-Zirlink+Primer) e fatores de “armazenamento” (ST-com, 150 dias/37º e sem). Após o tratamento superficial, foram construídos cinco cilindros (Ø=2mm; h=2,0mm) de cimento resinoso (n=15) em cada bloco cerâmico; ao final foi realizado o ensaio de resistência ao cisalhamento (1mm/min, 50Kgf) e análise de falhas superficiais. Foram confeccionadas 60 amostras adicionais (2x2x2mm) para análises extras (rugosidade superficial, MEV e EDS). Os dados de resistência de união e rugosidade superficial foram avaliados estatisticamente por ANOVA (2 fatores/1fator), teste de Tukey (5%) e análise de Weibull, respectivamente. ANOVA (2 fatores) revelou que todos os fatores foram estatisticamente significativos para a resistência de união. Os grupos de silicatização (SiST: 30,47AMPa; Si: 29,21AMPa) apresentaram os maiores valores de resistência de união, independente do armazenamento (Tukey). Enquanto os grupos tratados com Zirlink (ZST: 2,76FMPa; Z: 5,27EFMPa) apresentaram os valores mais baixos, apenas semelhantes ao grupo GlST (5,14EFMPa). O módulo de Weibull (m) apresentou diferença estatística entre os grupos (p=0,000). A ANOVA (1 fator) revelou que o fator “tratamento superficial” (p=0,0000) foi estatisticamente significativo para rugosidade superficial.

Abstract The objective is to evaluate the effect of different surface treatments and storage on the shear strength of ultratranslucent zirconia. 36 blocks of ultra-translucent zirconia were fabricated (7x7x2mm) and sintered. Then, divided into 12 groups according to the “surface treatment” (C -Primer; Al -Sandblasting with Al2O3 + Primer; Si -Silicate + Primer; Gl -Glaze + HF + Primer; Z -Zirlink; Zp -Zirlink + Primer) and “storage” factors (ST-with 150 days/37º and without). After surface treatment, five cylinders (Ø=2mm; h=2.0mm) of resin cement (n=15) were constructed in each ceramic block; at the end, the shear strength test was performed (1mm/min, 50Kgf), and analysis of surface failures. 60 additional samples (2x2x2mm) were made for extras analysis (surface roughness, MEV, and EDS). Bond strength and surface roughness data were statistically evaluated by ANOVA (2 factors/1 factor), Tukey test (5%), and Weibull analysis, respectively. ANOVA (2-way) revealed that all factors were statistically significant for bond strength. The silicatization groups (SiST: 30.47AMPa; Si: 29.21AMPa) showed the highest bond strength values, regardless of storage (Tukey's test). While the groups treated with Zirlink (ZST: 2.76FMPa; Z: 5.27EFMPa) showed the lowest values, just similar to the GlST group (5.14EFMPa). The Weibull modulus (m) showed a statistical difference between groups (p=0.000). ANOVA (1 factor) revealed that the "surface treatment" factor (p=0.0000) was statistically significant for surface roughness. Therefore, the application of Zirlink and Glaze on pre-sintered zirconia did not promote efficient adhesion of the ultratranslucent zirconia to the resin cement, even when associated with a primer containing MDP. 3 ultra translucent 7x7x2mm xxmm x mm (7x7x2mm sintered Then 1 treatment C Primer -Primer Sandblasting AlO O Al2O Silicate “storage STwith ST 15 days37º daysº days 37º º without. without . without) Ø=2mm Ø2mm Ømm Ø 2mm (Ø=2mm h=2.0mm h20mm hmm h 2 0mm n=15 n15 n (n=15 block end 1mm/min, 1mmmin mmmin 1mm min (1mm/min 50Kgf, 50Kgf Kgf , 50Kgf) failures 6 2x2x2mm (2x2x2mm MEV EDS.

RESUMO O câncer de pulmão (CP) é uma das neoplasias mais comuns e letais no Brasil, e apenas 15% dos pacientes são diagnosticados nos estágios iniciais. O tabagismo persiste como o responsável por mais de 85% de todos os casos. O rastreamento do CP (RCP) por meio da TC de baixa dosagem de radiação (TCBD) reduz a mortalidade do CP em 20%, e, quando combinado com a cessação do tabagismo, essa redução chega a 38%. Na última década, diversos países adotaram o RCP como recomendação de saúde populacional. No Brasil, embora ainda incipiente, a discussão sobre o tema é cada vez mais ampla e necessária. Com o intuito de aumentar o conhecimento e estimular o debate sobre o RCP, a Sociedade Brasileira de Cirurgia Torácica, a Sociedade Brasileira de Pneumologia e Tisiologia e o Colégio Brasileiro de Radiologia e Diagnóstico por Imagem constituíram um painel de especialistas para elaborar as recomendações para o RCP. As recomendações aqui apresentadas foram baseadas em revisão narrativa da literatura, com ênfase em grandes estudos populacionais, em revisões sistemáticas e em recomendações de diretrizes internacionais, sendo construídas após ampla discussão pelo grupo de especialistas. Os temas revisados foram os seguintes: porque rastrear, considerações gerais sobre tabagismo, epidemiologia do CP, critérios de elegibilidade, achados incidentais, lesões granulomatosas, modelos probabilísticos, requisitos mínimos da TCBD, aquisições volumétricas, riscos do rastreamento, estrutura mínima e papel da equipe multidisciplinar, conduta segundo o Lung CT Screening Reporting and Data System (Lung-RADS), custos vs. benefícios e perspectivas do rastreamento.

ABSTRACT Although lung cancer (LC) is one of the most common and lethal tumors, only 15% of patients are diagnosed at an early stage. Smoking is still responsible for more than 85% of cases. Lung cancer screening (LCS) with low-dose CT (LDCT) reduces LC-related mortality by 20%, and that reduction reaches 38% when LCS by LDCT is combined with smoking cessation. In the last decade, a number of countries have adopted population-based LCS as a public health recommendation. Albeit still incipient, discussion on this topic in Brazil is becoming increasingly broad and necessary. With the aim of increasing knowledge and stimulating debate on LCS, the Brazilian Society of Thoracic Surgery, the Brazilian Thoracic Association, and the Brazilian College of Radiology and Diagnostic Imaging convened a panel of experts to prepare recommendations for LCS in Brazil. The recommendations presented here were based on a narrative review of the literature, with an emphasis on large population-based studies, systematic reviews, and the recommendations of international guidelines, and were developed after extensive discussion by the panel of experts. The following topics were reviewed: reasons for screening; general considerations about smoking; epidemiology of LC; eligibility criteria; incidental findings; granulomatous lesions; probabilistic models; minimum requirements for LDCT; volumetric acquisition; risks of screening; minimum structure and role of the multidisciplinary team; practice according to the Lung CT Screening Reporting and Data System; costs versus benefits of screening; and future perspectives for LCS.

ABSTRACT Introduction: Heart transplantation is the gold standard for advanced heart failure treatment. This study examines the survival rates and risk factors for early mortality in adult heart transplant recipients at a Brazilian center. Methods: This retrospective cohort study involved 255 adult heart transplant patients from a single center in Brazil. Data were collected from medical records and databases including three defined periods (2012-2015, 2016-2019, and 2020-2022). Statistical analysis employed Kaplan-Meier survival curves, Cox proportional hazards analysis for 30-day mortality risk factors, and Log-rank tests. Results: The recipients were mostly male (74.9%), and the mean age was 46.6 years. Main causes of heart failure were idiopathic dilated cardiomyopathy (33.9%), Chagas cardiomyopathy (18%), and ischemic cardiomyopathy (14.3%). The study revealed an overall survival of 68.1% at one year, 58% at five years, and 40.8% at 10 years after heart transplantation. Survivalimproved significantly over time, combining the most recent periods (2016 to 2022) it was 73.2% in the first year and 63% in five years. The main risk factors for 30-day mortality were longer time on cardiopulmonary bypass, the initial period of transplants (2012 to 2015), older age of the donor, and nutritional status of the donor (overweight or obese). The main causes of death within 30 days post-transplant were infection and primary graft dysfunction. Conclusion: The survival analysis by period demonstrated that the increased surgical volume, coupled with the team’s experience and modifications to the immunosuppression protocol, contributed to the improved early and mid-term outcomes.

RESUMO A associação entre síndrome de Guillain-Barré (SGB) e citomegalovírus (CMV) já é bem estabelecida na literatura, tendo sido primeiramente relatada em 1967. Porém, essa associação é rara em pacientes transplantados de órgãos sólidos, apesar da incidência de infecção sintomática por CMV ser maior nesta população. Devido ao seu potencial de gravidade, alta morbidade e mortalidade, a possibilidade de SGB não pode ser afastada em caso de complicação neurológica em pacientes transplantados. Neste relato, é descrito um caso de SGB secundária a CMV em um paciente transplantado renal de 8 anos de idade, na faixa etária pediátrica, intervalo com ainda maior escassez de relatos sobre essa associação. O paciente apresentava sorologia (IgG e IgM) negativa para CMV em exames pré-transplante, enquanto o doador possuía IgG positiva, havendo dessa forma alto risco de desenvolvimento da doença. A abertura do quadro clínico ocorreu cerca de dois meses após a realização do transplante, com sintomas e evolução clássicos de SGB. São discutidos os aspectos clínicos, diagnósticos, de tratamento e de evolução da doença, além da relação com as evidências presentes na literatura mundial.

ABSTRACT The association between Guillain-Barré syndrome (GBS) and cytomegalovirus (CMV) is already well established in the literature, first reported in 1967. However, this association is rare in solid organ transplant patients, although the incidence of symptomatic CMV infection is higher in this population. Due to its potential severity, high morbidity and mortality, the possibility of GBS cannot be ruled out in the case of neurological complications in transplant patients. In this report, a case of GBS secondary to CMV is described in an eight-year-old kidney transplant patient in the pediatric age group, an interval with an even greater scarcity of reports on this association. The patient had negative antibodies (IgG and IgM) for CMV in pre-transplant tests, while the donor had positive IgG antibodies, meaning a higher risk of developing the disease. The clinical condition began approximately two months after the transplant, with classic symptoms and the evolution of GBS. The clinical aspects, diagnosis, treatment and evolution of the disease are discussed, in addition to the evidence in the world literature.

ABSTRACT Asbestos was largely used in Brazil. It is a mineral that induces pleural and pulmonary fibrosis, and it is a potent carcinogen. Our objective was to develop recommendations for the performance of adequate imaging tests for screening asbestos-related diseases. We searched peer-reviewed publications, national and international technical documents, and specialists’ opinions on the theme. Based on that, the major recommendations are: Individuals exposed to asbestos at the workplace for ≥ 1 year or those with a history of environmental exposure for at least 5 years, all of those with a latency period > 20 years from the date of initial exposure, should initially undego HRCT of the chest for investigation. Individuals with pleural disease and/or asbestosis should be considered for regular lung cancer monitoring. Risk calculators should be adopted for lung cancer screening, with a risk estimate of 1.5%. Brazil fibrosis carcinogen asbestosrelated related diseases peerreviewed peer reviewed publications documents specialists theme are 2 investigation andor monitoring 15 1.5% 1.5 1.

Abstract For good wound management, simultaneous phases during the wound healing process must be considered, including protection against infection, modulation of the inflammatory process, and proliferation and acceleration of cell migration. The aim of this study was to obtain Poly (Vinyl Pyrrolidone) (PVP) hydrophilic fibers containing polyhexamethylene biguanide (PHMB) and hyaluronic acid (HA) using the electrospinning technique to improve chronic wound treatment. Polymers mean hydrodynamic radius and polydispersity index (PdI) were measured by dynamic light scattering (DLS), whereas fiber morphology and diameter were evaluated by scanning electron microscopy (SEM). Also, Fourier transform infrared spectroscopy (FTIR) and contact angle measurements were performed. Fibers were obtained and presented homogenous morphology with a smooth surface. The FTIR study demonstrated an interaction between C=O groups of PVP and HA/PHMB in the PVP + HA/PHMB fibrous composites. Contact angle analysis has shown a hydrophilic characteristic of fibers produced. These findings demonstrate the great potential of electrospinning for developing drug-delivery systems with antimicrobial properties for wound healing treatment. management considered infection migration Vinyl Pyrrolidone (PVP PHMB (PHMB HA (HA treatment PdI (PdI DLS, DLS , (DLS) SEM.

ABSTRACT This study aimed to evaluate the duplicity and synergism of slow drying and storage processes at low temperatures, using a refrigerated room under suitable conditions for coffee fruit just after harvest. A cold room was prepared to receive and store coffee fruit in bulk directly from the field, perform slow drying, and maintain water content at approximately 12% during three months of storage. The room operated at temperatures between 7 and 14 ºC and relative humidity between 37 and 41%. The coffee variety used was the Conilon Yellow 62. The initial water content reduction period from 54% (wb) to 12% (wb) was two months. For comparison, coffee harvested from the same batch was dried on a covered suspended bed. Results showed that the coffee dried and stored in the cold room received a sensory score of 86.41, while that dried on a suspended bed obtained a sensory score of 84.16. Moreover, the coffee dried and stored in the cold room had a higher energy content. Colorimetric analysis showed that the dried grains stored in the cold room had a reduction in the "a" coordinate, indicating an approximation to the green color. The cold room also allowed for extended storage of the coffee grains. harvest field 12 1 3 41 41% 62 54 wb (wb comparison 8641 86 86.41 8416 84 16 84.16 Moreover "a coordinate color 4 6 5 864 8 86.4 841 84.1 86. 84.
