Metal encapsulation of waste foundry sand stabilized with alkali-activated binder: Batch and column leaching tests.

Waste stabilization processes are important to add value and reduce environmental risks related to metal contamination of soils and groundwater. This study evaluated the metal encapsulation of: (i) waste foundry sand (WFS) stabilized with an alkali-activated binder (AAB), compared to (ii) WFS-Portland cement (PC) mixture. The AAB was composed by sugar cane bagasse ash (SCBA), hydrated eggshell lime, and sodium hydroxide solution. The metal leaching behavior from WFS-AAB and WFS-PC was investigated through batch and column tests according to NBR 10005 and ASTM D4874 methods, respectively. All WFS-AAB and WFS-PC mixtures showed no metal toxicity. WFS-AAB matrices encapsulated the heavy metals Cd, Cr, and Pb from WFS and SCBA. Leaching results from NBR 10005 method were more favorable than ASTM D4874 for water quality limits (CONAMA 460, Dutch List, and EPA). Binder type, metals leaching patterns, and leaching test procedures were key factors in understanding the environmental performance of cemented WFS.

Tremellomycetes isolated from organs of Columba livia.

Brain, lungs, and intestines of Columba livia captured in Brazil were analyzed for research on Tremellomycetes. Mycological culture presented the growth of colonies suggestive of Cryptococcus spp. in 11.60% (13/112) of the samples. Microscopy revealed capsulated yeast cells. Molecular analysis evidenced Papiliotrema flavescens, Naganishia diffluens, Filobasidium magnum, and Naganishia randhawae. Thermotolerance of Tremellomycetes isolates from brain and lung (n = 10) evidenced cell growth and viability at 37 °C. At 42 °C/24 h, these isolates showed viability, except for one P. flavescens isolate. Here, we report the first isolation of Tremellomycetes species from the brain and lungs of a healthy C. livia.

The study reported the first isolation of Tremellomycetes species, including P. flavescens, N. diffluens, F. magnum, and N. randhawae from the organs of domestic pigeons. All isolates expressed important virulence factors such as capsule and thermotolerance, indicating their pathogenic potential.

Effects of vaccine registration on disease prophylaxis: a systematic review.

BACKGROUND: The impact of the pandemic caused by the coronavirus (SARS-CoV-2), causing the disease COVID-19, has brought losses to the world in terms of deaths, economic and health problems. The expected return of the public to activities adapted to the new health situation led to discussions about the use of vaccination and its effects. However, the demand for proof of vaccination showed how inconsistent, unregistered, and uncontrolled this health process is with current technologies. Despite the proven effectiveness of vaccines in reducing infection rates, mortality, and morbidity, there are still doubts about their use in preventing certain infections and injuries, as well as the use of digital medical records for identification at public events and disease prevention. Therefore, this review aims to analyze the use of digital immunization cards in disease prevention in general. METHODS: A systematic review of Science, PubMed/MEDLINE, LILACS /BSV, CINALH, and IEEE and Xplore was performed using PRISMA guidelines. The authors summarized the studies conducted over the last decade on the impacts of prophylaxis by control through immunization cards. Studies were selected using the following terms: Vaccination; Mobile Applications; Health Smarts Cards; Immunization Programs; Vaccination Coverage. For data analysis, we used Mendeley, Excel, RStudio, and Bibliometrix software among others. RESULTS: A total of 1828 publications were found. After applying eligibility criteria (Articles published in Portuguese, Spanish or English in the last 10 years). Studies that only dealt with paper or physical records were excluded, as well as studies that were not linked to their country's health Department, as a possibility of bias exists with these types of information). After removing duplicates and applying filters 1 and 2, we included 18 studies in this review. This resulted in 18 papers that met our priori inclusion criteria; it was found that the most relevant sources were from the databases of the Institute of Electrical and Electronics Engineers (IEEE). CONCLUSIONS: Considering the selected studies, we found that scientific evidence and epidemiological surveillance are essential tools to characterize the efficiency and effectiveness of immunization passport protection intervention and to ethically justify them. Technological development of digital vaccine passports can assist in vaccination programs and positively impact disease prophylaxis.

The relation between columbiform birds (Columba livia) age and gender and infection indices of rhinonyssid and ereynetid mites.

Respiratory systems of birds may be parasitized by rhinonyssid and ereynetid mites, which are commonly found in their nasal cavities. Levels of infection caused by mites in relation to maturity and gender of birds have been poorly investigated. Although Columba livia is the host of both Tinaminyssus and Trispeleognathus species worldwide, there are no data on prevalence and mean intensity of infection by mites in immature and adult males and females. Therefore, this study aims to analyze infections in relation to characteristics of hosts in southern Brazil. In the sample of 160 birds under study, 24.38% were parasitized by rhinonyssid mites (Tinaminyssus melloi and Tinaminyssus columbae) while 5.0% were infested with ereynetid ones (Trispeleognathus striatus). Infections by rhinonyssid mites in immature and adult birds, as well as in male and female ones, were similar and there were no significant differences in prevalence and mean intensity of infection. However, when infections were analyzed separately, prevalence of T. melloi was significantly higher in immature (19.77%) than in adult (6.76%) birds (p = 0.021). Ereynetid mites, which parasitized only males, were more prevalent in adult (9.46%) than in immature (1.16%) birds (p = 0.025). Reproductive and behavioral characteristics of C. livia (e.g., year-round breeding and social behavior) may enable transmission and maintenance of mite populations, since direct contact among hosts and the presence of mites in their nests are considered forms of transmission. Even though information on the life history of mites is important to understand parasite-host relations, there is a gap in the biology of species commonly found in C. livia, which constitutes an area to be explored.

Ivabradine plus conventional treatment vs conventional treatment alone in reducing the mean heart rate in heart transplant recipients: A randomized clinical trial.

The absence of afferent nerves for heart rate (HR) regulation leaves the transplanted heart under the influence of its internal and hormonal control. The HR of heart transplantation (HTx) recipients varies from to 90-110 bpm, indicating a lack of vagal parasympathetic tone. We hypothesized that the reduction in mean HR using an If-channel antagonist (ivabradine) could be effective and safe in HTx recipients. The primary objective of this open-label randomized clinical trial was to compare the mean HR at 3, 6, 12, 18, 24, 30, and 36 months after randomization between an ivabradine plus conventional treatment group (IG) and conventional treatment alone group (CG). The secondary objectives were reduction in mortality, graft dysfunction, and ventricular mass. All patients were randomized between 1 and 12 months after HTx. Ivabradine started at randomization. Of the 35 patients, 54.28% were in the CG and 45.72% in the IG. There were no significant between-group differences in demographics. Over time, the HR differences between the groups became significant (P < .01). There were no significant between-group differences in mortality, graft dysfunction, and ventricular mass. We conclude that ivabradine could effectively and consistently reduce the HR in HTx recipients.

Yellow Fever Virus Reemergence and Spread in Southeast Brazil, 2016-2019.

The recent reemergence of yellow fever virus (YFV) in Brazil has raised serious concerns due to the rapid dissemination of the virus in the southeastern region. To better understand YFV genetic diversity and dynamics during the recent outbreak in southeastern Brazil, we generated 18 complete and nearly complete genomes from the peak of the epidemic curve from nonhuman primates (NHPs) and human infected cases across the Espírito Santo and Rio de Janeiro states. Genomic sequencing of 18 YFV genomes revealed the estimated timing, source, and likely routes of yellow fever virus transmission and dispersion during one of the largest outbreaks ever registered in Brazil. We showed that during the recent epidemic, YFV was reintroduced from Minas Gerais to the Espírito Santo and Rio de Janeiro states multiple times between 2016 and 2019. The analysis of data from portable sequencing could identify the corridor of spread of YFV. These findings reinforce the idea that continued genomic surveillance strategies can provide information on virus genetic diversity and transmission dynamics that might assist in understanding arbovirus epidemics.IMPORTANCE Arbovirus infections in Brazil, including yellow fever, dengue, zika, and chikungunya, result in considerable morbidity and mortality and are pressing public health concerns. However, our understanding of these outbreaks is hampered by the limited availability of genomic data. In this study, we investigated the genetic diversity and spatial distribution of YFV during the current outbreak by analyzing genomic data from areas in southeastern Brazil not covered by other previous studies. To gain insights into the routes of YFV introduction and dispersion, we tracked the virus by sequencing YFV genomes sampled from nonhuman primates and infected patients from the southeastern region. Our study provides an understanding of how YFV initiates transmission in new Brazilian regions and illustrates that genomics in the field can augment traditional approaches to infectious disease surveillance and control.

The emerging role of metallic nanoparticles in food.

Nanotechnology is widely used in biomedical applications, engineering sciences, and food technology. The application of nanocompounds play a pivotal role in food protection, preservation, and increasing its shelf life. The changing lifestyle, use of pesticides, and biological and/or chemical contaminants present in food directly affect its quality. Metallic nanoparticles (MNPs) are useful to develop products with antimicrobial activity and with the potential to improve shelf life of food and food products. Due to the prevention of microbial growth, MNPs have attracted the attention of researchers. Biopolymers/polymers can be easily combined with different MNPs which act as a vehicle not only for one type of particles but also as a hybrid system that allows a combination of natural compounds with metallic nanocompounds. However, there is a need for risk evaluation to use nanoparticles in food packaging. In this review, we aim to discuss how MNPs incorporated into polymers/biopolymers matrices can be used for food preservation, considering the quality and safety, which are desirable in food technology.

Aptima Trichomonas vaginalis assay elucidates significant underdiagnosis of trichomoniasis among women in Brazil according to an observational study.

OBJECTIVES: Trichomonas vaginalis (TV) infection is the most common non-viral STI globally and can result in adverse pregnancy outcomes and exacerbated HIV acquisition/transmission. Nucleic acid amplification tests (NAATs) are the most sensitive diagnostic tests, with high specificity, but TV NAATs are rarely used in Brazil. We investigated the TV prevalence and compared the performance of the US Food and Drug Association-cleared Aptima TV assay with microscopy (wet mount and Gram-stained) and culture for TV detection in women in Pelotas, Brazil in an observational study. METHODS: From August 2015 to December 2016, 499 consecutive asymptomatic and symptomatic sexually active women attending a Gynaecology and Obstetrics Outpatient Clinic were enrolled. Vaginal fluid and swab specimens were collected and wet mount microscopy, Gram-stained microscopy, culture and the Aptima TV assay performed. RESULTS: The median age of enrolled women was 36.5 years (range: 15-77). The majority were white, had a steady sexual partner and low levels of education. The TV detection rate was 4.2%, 2.4%, 1.2% and 0% using the Aptima TV assay, culture, wet mount microscopy and Gram-stained microscopy, respectively. The sensitivity of culture and wet mount microscopy was only 57.1% (95% CI 36.5 to 75.5) and 28.6% (95% CI 13.8 to 50.0), respectively. CONCLUSIONS: A 4.2% positivity rate of T. vaginalis was found among women in Pelotas, Brazil and the routine diagnostic test (wet mount microscopy) and culture had low sensitivities. More sensitive diagnostic tests (NAATs) and enhanced testing of symptomatic and asymptomatic at-risk women are crucial to mitigate the transmission of TV infection, TV-associated sequelae and enhanced HIV acquisition and transmission.

Donor hypernatremia and smoking addiction contribute to primary graft failure in heart transplantation.

INTRODUCTION: Primary graft failure (PGF) is an important contributor to early mortality, accounting for 41% of deaths within the first 30 days after heart transplantation (HT). Donor hypernatremia has been associated with PGF development. However, controversial data exist regarding the impact of sodium deregulation in patient survival after HT. This study aimed to assess the influence of donor hypernatremia on PGF development and to determine the serum sodium level threshold to assist in decision-making for organ procurement. METHODS: The medical record from 200 HT patients and organ donors were retrospectively assessed and categorized by PGF occurrence. Donor sodium levels were compared and cut-off points obtained by receiver operating characteristic (ROC) curve. A multiple logistic regression model was applied to assess the effects of factors and covariates that influence PGF development. RESULTS: Sodium levels of donors were significantly higher in recipients who developed PGF than those who did not develop PGF (162 vs. 153 mmol/L, P = .001). The sodium cut-off value determined by the ROC curve was 159 mmol/L. The group who received organs from donors with a serum sodium concentration ≥159 mmol/L had a higher incidence of PGF (63.3% vs 32.4%, P < .001). Furthermore, donor sodium levels ≥159 mmol/L increased the likelihood of recipients developing PGF by 3.4 times. It is also observed that the incidence of donor smoking addiction was significantly higher in the PGF group (28.6% vs. 11.5%, P = .004) and donor smoking addiction increased the risk of developing PGF by 2.8 times. CONCLUSION: Smoking addiction and the application of suboptimal organs from donors with hypernatremia contribute to primary graft failure in heart transplantation.

Determination of 17α-ethinylestradiol and toxic metals in surface waters, and estimation of daily intake.

The presence of substances such as hormones and toxic metal in aquatic ecosystem is interesting to the scientific community due to their adverse effects. We quantified 17α-ethynylestradiol (EE2) and toxic metals in the surface waters from Sorocaba and Pirajibu Rivers, in São Paulo State, and we estimated the daily intake for hormone, based on the amount of water consumed. EE2, Cd, Hg, As, Pb, and Mn were seasonally quantified in six different locations along the rivers. EE2 was evaluated by high-performance liquid chromatography. Toxic metals were determined by inductively coupled plasma mass spectrometer. Considering the entire sample year, EE2 concentrations ranged from 4.5 to 48.2 µg L-1. Comparing Sorocaba and Pirajibu rivers, the sample point in the entrance of the Pirajibu River through the city of Itu, São Paulo State, had higher amounts of EE2. Regarding metals, all results are according to the Brazilian and World Health Organization guidelines for drinking-water quality, except for Mn levels, which were higher than the limits in Autumn season in two locations. The estimated daily intake ranged from 13.45 to 40.9 µg/day/person. In conclusion, concentrations of EE2 in the Sorocaba and Pirajibu Rivers were higher than in other countries. The levels were as high as an intake of one pill for each person every day (considering an oral contraceptive has 0.03 mg of ethinylestradiol). Even though concentrations of toxic elements are in accordance with the Brazilian Regulation and World Health Organization, legislation for hormones and drugs needs to advance.

Association of Silver Nanoparticles and Curcumin Solid Dispersion: Antimicrobial and Antioxidant Properties.

The last century, more precisely after 1945, was marked by major advances in the treatment of infectious diseases which promoted a decrease in mortality and morbidity. Despite these advances, currently the development of antimicrobial resistance has been growing drastically and therefore there is a pressing need to search for new compounds. Silver nanoparticles (AgNps) have been demonstrating good antimicrobial activity against different bacteria, viruses, and fungi. Curcumin (CUR) extracted from rhizomes of Curcuma longa has a variety of applications including antiinflammatory, antioxidant, and antibacterial agent. The association between silver nanoparticles and curcumin in a formulation can be a good alternative to control infectious diseases due the antimicrobial properties of both compounds. The objective of this work was to develop a formulation composed of a thermoresponsive gel-with antimicrobial and antioxidant properties due to the association of AgNps with PVP and PVA polymers. After AgNp synthesis, these were incorporated together with the previously prepared CUR/P407 (1:2) solid dispersion (SD) into a polymer dispersion of 20% P407 (thermosensitive gel). Our results showed that the association between the AgNps with CUR SD demonstrated good antioxidant activity as compared to the standard compound. Measures of MIC showed more efficacy against Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa) than for Gram-positive bacteria (Staphylococcus aureus). This association enhances antimicrobial activity against E. coli and P aeruginosa and added antioxidant value in formulations.

Natural colorants from filamentous fungi.

In the last years, there is a trend towards the replacement of synthetic colorants by natural ones, mainly due to the increase of consumer demand for natural products. The natural colorants are used to enhance the appearance of pharmaceutical products, food, and different materials, making them preferable or attractive. This review intends to provide and describe a comprehensive overview of the history of colorants, from prehistory to modern time, of their market and their applications, as well as of the most important aspects of the fermentation process to obtain natural colorants. Focus is given to colorants produced by filamentous fungal species, aiming to demonstrate the importance of these microorganisms and biocompounds, highlighting the production performance to get high yields and the aspects of conclusion that should be taken into consideration in future studies about natural colorants.

Microbial diversification of Diels-Alder cycloadducts by whole cells of Penicillium brasilianum.

Functionalizations of cycloadducts are important steps for the use of Diels-Alder reactions in the construction of complex cyclic or polycyclic molecules from relatively simple starting materials. In the present work, we studied the ability of Penicillium brasilianum to perform microbial transformations of racemic Diels-Alder endo-cycloadducts. Thus, Diels-Alder products, obtained from reacting cyclopentadiene or 2,3-dimethylbutadiene with alkylated para-benzoquinones, were transformed by the resting cells of P. brasilianum producing new functionalized polycyclic compounds. These biotransformations yielded novel products of oxidation and ring closure, reduction of the C=C or C=O in [Formula: see text]-unsaturated system, and allylic hydroxylations. The reduction products (conjugated double bond and carbonyl group) were also synthesized, and the enantioselectivity of both in vitro and in vivo processes was evaluated. In all cases, the microbiological transformations were enantioselective. In silico docking studies of the Diels-Alder cycloadducts with P. brasilianum oxidoreductase "old yellow enzymes" shed more light on these transformations.

Anticancer activities of Withania somnifera: Current research, formulations, and future perspectives.

CONTEXT: Cancer, being a cause of death for major fraction of population worldwide, is one of the most studied diseases and is being investigated for the development of new technologies and more accurate therapies. Still the currently available therapies for cancer have many lacunae which affect the patient's health severely in the form of side effects. The natural drugs obtained from the medicinal plants provide a better alternative to fight against this devastating disease. Withania somnifera L. Dunal (Solanaceae), a well-known Ayurvedic medicinal plant, has been traditionally used to cure various ailments for centuries.

RESULTS: Various parts of W. somnifera especially the roots with its unique contents have been proved effective against different kinds of cancers. The most active components withanolides and withaferins along with a few other metabolites including withanone (WN) and withanosides have been reported effective against different types of cancer cell lines. CONCLUSION: This herb holds an important place among various anticancer medicinal plants. It is very essential to further screen and to investigate different formulations for anticancer therapy in vitro as well as in vivo in combination with established chemotherapy.

Bacterial cellulose production by Gluconacetobacter xylinus by employing alternative culture media.

Bacterial cellulose (BC) is used in different fields as a biological material due to its unique properties. Despite there being many BC applications, there still remain many problems associated with bioprocess technology, such as increasing productivity and decreasing production cost. New technologies that use waste from the food industry as raw materials for culture media promote economic advantages because they reduce environmental pollution and stimulate new research for science sustainability. For this reason, BC production requires optimized conditions to increase its application. The main objective of this study was to evaluate BC production by Gluconacetobacter xylinus using industry waste, namely, rotten fruits and milk whey, as culture media. Furthermore, the structure of BC produced at different conditions was also determined. The culture media employed in this study were composed of rotten fruit collected from the disposal of free markets, milk whey from a local industrial disposal, and their combination, and Hestrin and Schramm media was used as standard culture media. Although all culture media studied produced BC, the highest BC yield-60 mg/mL-was achieved with the rotten fruit culture. Thus, the results showed that rotten fruit can be used for BC production. This culture media can be considered as a profitable alternative to generate high-value products. In addition, it combines environmental concern with sustainable processes that can promote also the reduction of production cost.

Duddingtonia flagrans in the control of gastrointestinal nematodes of horses.

Horses can harbor a large amount of parasites that may cause serious clinical signs even death. The aim of this study was to evaluate the predatory activity of the fungus Duddingtonia flagrans against infective larvae (L3) of gastrointestinal nematodes of horses in fecal culture. The experimental design was completely randomized with three treated groups (G1, G2 and G3) and one control (CG), using eight animals/group. The treated animals received G1: 1.5 × 10(5); G2: 3 × 10(5) and G3: 6 × 10(5) chlamydospores of D. flagrans/kg body weight during 21 days. The fungi preparation was given at every other three-day interval. Faecal samples were collected during 30 days, on the same interval, to perform the fecal egg counts (EPG) and fecal culture for each horse. All groups demonstrated similar results for the EPG (P > 0.05) counts. D. flagrans significantly reduced (P < 0.05) the number of infective larvae after 72 h-interval between treatments. The G2 and G3 promoted higher results (P < 0.05) of L3 reduction compared to the CG. The biological control with the predacious fungi D. flagrans is still a promising free-living parasite regulator alternative to be use in livestock.

Following the needles: an anatomical study to evaluate the postoperative safety and symptoms of patients receiving a transobturator male sling implant.

PURPOSE: Implanting a transobturator male sling is a valid option to manage urinary incontinence after prostatectomy. We evaluated the trajectory of Argus T™ needles blindly introduced into the retropubic space to determine the safety and etiology of postoperative symptoms that can arise from this implant. MATERIALS AND METHODS: Needles were implanted and perineal dissection was performed in 20 fixed, adult human male cadavers. The distance was measured from the upper and lower extremities of the needles in the internal pelvic wall up to the obturator neurovascular bundle. Anatomical variations identified in this area proximal to the needles were characterized. The inguinocrural region was also dissected from the needles positioned there. Statistical analysis of the results was done. RESULTS: All needles transfixed the obturator internus muscle. Of the needles 90% were completely immersed in its fibers and not visible in the inner wall of the pelvis. The distance to the obturator neurovascular bundle and anatomical variations were noted. In the inguinocrural region the pectineus and adductor longus muscles were perforated in all cadavers. CONCLUSIONS: The needle sling implant preserves the obturator neurovascular bundle and obviates the potential for postoperative pelvic hematoma. The anatomical trajectory of the needles used for this implant account for the groin and perineal pain side effects. Based on similarities between the Argus T and other types of outside-in transobturator male slings the results of the current study could be extrapolated to the latter slings.

Exploring the interplay between miRNAs, apoptosis and viral load, in Dengue virus infection.

Dengue virus (DENV) is a major global health concern, causing millions of infections annually. Understanding the cellular response to DENV infection is crucial for developing effective therapies. This study provides an in-depth analysis of the cellular response to Dengue virus (DENV) infection, with a specific focus on the interplay between microRNAs (miRNAs), apoptosis, and viral load across different DENV serotypes. Utilizing a variety of cell lines infected with four DENV serotypes, the research methodically quantifies viral load, and the expression levels of miRNA-15, miRNA-16, and BCL2 protein, alongside measuring apoptosis markers. Methodologically, the study employs quantitative PCR for viral load and miRNA expression analysis, and Western blot for apoptosis and BCL2 detection, with a statistical framework that includes ANOVA and correlation analysis to discern significant differences and relationships. The findings reveal that despite similar viral loads across DENV serotypes, DENV-2 exhibits a marginally higher load. A notable upregulation of miRNA-15 and miRNA-16 correlates positively with increased viral load, suggesting their potential role in modulating viral replication. Concurrently, a marked activation of caspases 3 and 7, along with changes in BCL2 protein levels, underscores the role of apoptosis in the cellular response to DENV infection. Conclusively, the study enhances the understanding of miRNA involvement in DENV pathogenesis, highlighting miRNA-15 and miRNA-16 as potential regulatory agents in viral replication and apoptosis. These findings pave the way for further exploration into miRNA-based therapeutic strategies against DENV infection.

Ecotoxicological study of seven pharmaceutically active compounds: Mixture effects and environmental risk assessment.

Pharmaceutically active compounds (PhACs) have been detected in several aquatic compartments, which has been of environmental concern since PhACs can cause adverse effects on the aquatic ecosystem at low concentrations. Despite the variety of PhACs detected in surface water, ecotoxicological studies are non-existent for many of them, mainly regarding their mixture. In addition, water bodies can continuously receive the discharge of raw or treated wastewater with micropollutants. Thus, PhACs are subject to mixture and interactions, potentiating or reducing their toxicity. Therefore, the present study evaluated the toxicity on Aliivibrio fischeri of seven PhACs, which still needs to be explored in the literature. The effects were evaluated for the PhACs individually and for their binary and tertiary mixture. Also, the experimental effects were compared with the concentration addition (CA) and independent action (IA) models. Finally, an environmental risk assessment was carried out. Fenofibrate (FEN), loratadine (LOR), and ketoprofen (KET) were the most toxic, with EC50 of 0.32 mg L-1, 6.15 mg L-1 and 36.8 mg L-1, respectively. Synergistic effects were observed for FEN + LOR, KET + LOR, and KET + FEN + LOR, showing that the CA and IA may underestimate the toxicity. Environmental risks for KET concerning algae, and LOR e 17α-ethynylestradiol (EE2) for crustaceans and fish were high for several locations. Besides, high removals by wastewater treatment technologies are required to achieve the concentrations necessary for reducing KET and LOR risk quotients. Thus, this study contributed to a better understanding of the toxic interactions and environmental risks of PhACs.
