Human papillomavirus (HPV) infections rank as the most prevalent sexually transmitted infections globally. The Brazilian Ministry of Health recommends the topical use of 70%-90% trichloroacetic acid (TAA) for treating condyloma acuminata, yet this method suffers from a high recurrence rate of 36% and requires roughly six applications. Topical photodynamic therapy (PDT) has shown effectiveness in targeting subclinical lesions, but it also necessitates multiple sessions for complete lesion clearance.

Background: Patients on maintenance hemodialysis (HD) face complications due to the accumulation of protein-bound uremic toxins, such as advanced glycation end products (AGEs), which contribute to inflammation, oxidative stress, and cardiovascular disease. Conventional HD techniques inadequately remove AGEs. This study evaluates the efficacy of the HA130 hemoadsorption cartridge combined with high-flux HD (HF-HD) in enhancing AGE removal.

Objectives: This experimental study compared the accuracy of implant insertion using the free-hand (FH) technique, static computer-aided surgery (S-CAIS), or dynamic computer-assisted surgery (D-CAIS) and to evaluate the correlation of learning curves between surgeons' experience and surgical time.
Materials And Methods: Thirty-six models were randomly assigned to three groups (FH, n = 12; S-CAIS, n = 12; D-CAIS, n = 12). Each model was planned to receive four implants in the maxillary anterior and posterior regions.

This research was designed to investigate the metabolite profiling, phenolics content, and the trypanocidal, nematicidal, antibacterial, antifungal, and free radical scavenging properties of Motyka. The air-dried material was extracted successively with dichloromethane and methanol (UlMeOH). Two phases were obtained from the extract with dichloromethane, one soluble in methanol (UlDCM-s) and the other insoluble (UlDCM-i).

Our article deals with the governance of responsible research and innovation (RRI) and aims to set out a first psychologically grounded decision-theoretic method for the governance of RRI. We approach the governance of RRI as a multicriteria group decision analysis problem of delivering social welfare in an innovation ecosystem. Following such a methodological approach, we develop a psychologically grounded multicriteria group decision analysis method that integrates in its value function the main psychological effects captured in the value function of prospect theory as the main theory of individual decision-making under risk.

The Neural Crest cells are multipotent progenitor cells formed at the neural plate border that differentiate and give rise to a wide range of cell types and organs. Directional migration of NC cells and their correct positioning at target sites are essential during embryonic development, and defects in these processes results in congenital diseases. The NC migration begins with the epithelial-mesenchymal transition and extracellular matrix remodeling.

Background: The prevalence of colorectal cancer (CRC) in patients with ulcerative colitis (UC) is higher than in the general population, in Latin America there is a progressive increase of UC, and information about CRC screening in inflammatory bowel disease (IBD) is scarce. The aim of this study was to analyze the findings of endoscopic surveillance of CRC in patients with IBD according to available technology.
Methods: Multicenter, cross-sectional, analytical study conducted in Latin American countries, in patients with UC, predominantly with more than 8 years of diagnosis and different degrees of disease activity.

Dado el aumento constante en la tasa de incidencia del VIH en Chile, se han impulsado estrategias de prevención conjunta, con la promoción del testeo de VIH como uno de sus pilares fundamentales. El presente estudio se propuso identificar los determinantes sociales del testeo de VIH en la población chilena a partir de datos secundarios provenientes de la Encuesta Nacional de Salud, Sexualidad y Género 2022-2023. Se contó con un diseño transversal y una muestra representativa de 20392 adultos chilenos residentes en sectores urbanos.

Science is crucial for evidence-based decision-making. Public trust in scientists can help decision makers act on the basis of the best available evidence, especially during crises. However, in recent years the epistemic authority of science has been challenged, causing concerns about low public trust in scientists.

Science is integral to society because it can inform individual, government, corporate, and civil society decision-making on issues such as public health, new technologies or climate change. Yet, public distrust and populist sentiment challenge the relationship between science and society. To help researchers analyse the science-society nexus across different geographical and cultural contexts, we undertook a cross-sectional population survey resulting in a dataset of 71,922 participants in 68 countries.

Families have been subject to enormous transformations with the emergence of artificial reproductive technology and the appearance of donor-conceived children. These new families are challenged to disclose origins with their children and parents feel concern that conception stories might have an emotional impact on their children. Fertility counsellors still feel ill-equipped on what to recommend to parents because developmental psychology has not designed systematic evidence-based guidelines to address a three-dimensional matter: 'what', 'when', and 'how' to discuss conception stories.

Toluidine blue O (TBO) is a type I-type II photosensitizer that has shown good efficacy and selectivity in antimicrobial and anticancer photodynamic therapy applications. However, its complex photochemistry with multiple photoproducts hinders its application as a photosensitizer. We have previously described the mechanism for photooxidative demethylation of TBO which in acetonitrile yields two main products: demethylated-TBO (d-TBO) and double-demethylated-TBO (dd-TBO).

Environmental stress on early life stages has severe consequences for individual performance and population dynamics. The internal incubation process of the symbiotic intertidal anemone Anthopleura hermaphroditica ends when the juveniles leave the gastrovascular cavity of the adult, at which moment they are exposed to a highly stressful environment due to tidal changes and environmental radiation in the Quempillén estuary. To determine the cellular and physiological tolerance capabilities of juvenile anemones to changes in salinity and environmental radiation resulting from the abandonment of the gastrovascular cavity, an experiment with an orthogonal design was performed on individuals exposed to four levels of salinity (30.

Background: A small number of reviews have explored lower- versus higher-volume training in non-athletes, but the growing challenge of congested schedules in team sports highlights the need to synthesize evidence specific to team sport athletes. Thus, the objectives of this systematic review with meta-analysis are twofold: (i) to summarize the primary physiological and physical fitness outcomes of lower-volume versus higher-volume training interventions in team sports players; and (ii) to compare the effects of lower-volume training with higher, considering the training modalities used.
Methods: We conducted searches across key databases, including PubMed, Scopus, SPORTDiscus, and Web of Science.

Promoting incidental physical activity (IPA) can help reduce sedentary lifestyles and physical inactivity levels in the population. However, there is heterogeneity in the definition of IPA, and studies have yet to synthesize the empirical findings on this topic. This review aimed to (1) Synthesize the definitions of the IPA used in the scientific literature, (2) Identify the behaviors part of the IPA, and (3) Synthesize the main findings on IPA.

This study explored gross motor development (GMD) trajectories among 6359 children, with and without autism, from the Growing Up in New Zealand longitudinal cohort study. By the age of 8, 173 children had either an autism diagnosis (n = 108) or parent-reported autism concerns (n = 65). Gross motor milestones were reported by mothers when children were 9, 24, and 54 months of age.

The Simons Observatory (SO) is a cosmic microwave background (CMB) experiment located in the Atacama Desert in Chile that will make precise temperature and polarization measurements over six spectral bands ranging from 27 to 285 GHz. Three small aperture telescopes (SATs) and one large aperture telescope (LAT) will house 60,000 detectors and cover angular scales between one arcminute and tens of degrees. We present the performance of the dichroic, low-frequency (LF) lenslet-coupled sinuous antenna transition-edge sensor (TES) bolometer arrays with bands centered at 27 and 39 GHz.
