Discrimination and Stigma Associated with Obesity: A Comparative Study between Spain and Egypt. Data from the OBESTIGMA study.

INTRODUCTION: This study explores the under-investigated area of obesity-related discrimination and stigmatization across different countries, specifically comparing Spain (Europe) and Egypt (Middle East). METHODS: We conducted a cross-sectional observational study involving 2,090 participants from both countries. Participants completed three well-validated questionnaires to assess their attitudes towards obesity, experiences of weight-related stigma, and internalization of weight bias: Antifat Attitudes Scale (AFA), Stigmatizing Situations Inventory (SSI), and Weight Bias Internalization Scale (WBIS). Participants were categorized into four groups based on BMI and history bariatric surgery. RESULTS: Egyptian participants [BMI = 30.2±6.7 kg/m2 (range: 18.5 to 69.0 kg/m2)] showed significantly higher aversion towards obesity, as indicated by higher AFA score, compared to their Spanish counterparts [BMI = 35.4±10.1 kg/m2 (18.5 to 71,9 kg/m2)]. In contrast, Spanish participants reported higher levels of weight bias internalization with increasing BMI, while in Egypt, this association was negative. The association of bariatric surgery on stigma reduction also differed between the countries. Multivariate analysis revealed that residing in Egypt was an independent risk factor for higher scores in AFA and WBIS (Odds Ratio 8.20 [95% confidence interval: 6.78 to 9.62], p<0.001 and OR 6.28 [95% CI: 4.78 to 7.78], p<0.001; respectively). In contrast, Spaniards experienced more stigmatizing situations than Egyptians [OR -2.54 (95% CI: 6.78 to 9.62), p<0.001]. CONCLUSION: Our study underscore the complex and diverse nature of obesity-related attitudes across cultures. Understanding these cultural differences is crucial for developing effective, culturally sensitive strategies to tackle weight stigma. This research opens avenues for further studies and interventions tailored to cultural contexts.

The Relationship between Healthy Vascular Aging with the Mediterranean Diet and Other Lifestyles in the Spanish Population: The EVA Study.

The aim of this study was to analyze the relationship between healthy vascular aging (HVA) and the Mediterranean diet alongside other lifestyles in a Spanish population aged 35 to 75 years without previous cardiovascular diseases. METHODS: In this cross-sectional descriptive study, 501 individuals aged 35 to 75 years were recruited from five health centers by random sampling stratified by age and sex (55.90 ± 14.24 years, 49.70% men). HVA was determined in two steps. Step 1: Subjects with vascular damage to the carotid arteries or peripheral arterial disease were classified as non-HVA. Step 2: The study population was classified by age and sex using the percentiles of the vascular aging index (VAI), with VAI ≤p25 considered HVA and >p25 considered non-HVA. The VAI was estimated using the following formula (VAI = (log (1.09) × 10 cIMT + log (1.14) cfPWV) × 39.1 + 4.76. Carotid-femoral pulse wave velocity (cfPWV) was measured with the SphygmoCor® device, and carotid intima-media thickness using Sonosite Micromax® ultrasound. Mediterranean diet (MD) adherence, alcohol and tobacco use were recorded through validated questionnaires. Physical activity was assessed with the ActiGraph-GT3X® accelerometer. RESULTS: The mean VAI value was 61.23 ± 12.86 (men-63.47 ± 13.75 and women-59.04 ± 11.54; p < 0.001). HVA was found in 18.9% (men-19.9% and women-17.8%). In the multiple regression analysis after adjusting for possible confounding factors, the mean VAI value showed a positive association with alcohol use (ß = 0.020) and sedentary hours per week (ß = 0.109) and a negative association with hours of activity per week (ß = -0.102) and with the number of healthy lifestyles (ß = -0.640). In the logistic regression analysis, after adjusting for possible confounding factors and compared to those classified as non-HVA, subjects classified as HVA were more likely to show MD adherence (OR = 0.571), do more than 26 h per week of physical activity (OR = 1.735), spend under 142 h per week being sedentary (OR = 1.696), and have more than two healthy lifestyles (OR = 1.877). CONCLUSION: The results of this study suggest that the more time spent doing physical activity and the less time spent in a sedentary state, the lower the vascular aging index and the greater the likelihood of being classified in the group of subjects with HVA.

Pigmented acuminated condylomas seborrhoeic keratosis-like: a new entity?

BACKGROUND: Condyloma acuminatum is caused by human papillomavirus (HPV), which typically presents as excrescent, pedunculated, papillomatous lesions which may be of a pale colour. On rare occasions, we have observed pigmented genital lesions that are similar to seborrhoeic keratoses, but with histological findings of condyloma acuminatum and positive genotyping for HPV. We have termed these 'seborrhoeic keratosis-like' type condylomas. METHODS: This is an observational retrospective study. The following clinical data were collected: age, sex, time of evolution, location, isolated or multiple lesions, monomorphous or polymorphous/mixed lesions. HPV genotyping was performed in all cases, and excision for histological study in eight cases. RESULTS: A total of 31 patients were diagnosed with this type of pigmented condylomata acuminata. Of these, 16 had isolated lesions (less than five lesions) and 15 had multiple lesions. 67% of the lesions exhibited slow growth, with an evolution period of greater than 1 year. The most frequent location was the base of the penis and pubis. HPV genotyping of the lesions was positive in all cases, with the HPV-6 genotype predominating (28 cases, 90.3%). The lesions exhibited dermoscopic differences from other pigmented lesions and histological findings attributable to HPV infection (pseudoparakeratosis, koilocytosis, etc) and others similar to those observed in seborrhoeic keratoses. CONCLUSIONS: A total of 31 patients were diagnosed with pigmented verrucous lesions, excrescents, isolated or multiple, in the genital region. These lesions exhibited clinical characteristics similar to seborrhoeic keratoses, with positive genotyping for HPV. In the majority of cases, the genotype was HPV-6. These lesions have been named 'pigmented condylomata acuminata seborrhoeic keratosis-like'. Only 10 cases of these lesions have been described in the literature.

Effect of a novel copper chloride gel on endometrial growth and function in healthy volunteers.

RESEARCH QUESTION: Does the application of a micro-dose of copper chloride gel increase endometrial production of vascular endothelial growth factor (VEGF) without compromising endometrial function or producing embryo toxicity? DESIGN: An estimate of optimal dose was made based on cell culture studies. Ten healthy participants received an initial uterine application of placebo gel, followed by copper chloride gel (37.5 µM, 75 µM, or 150 µM dose) in a later hormone replacement cycle. Endometrial biopsies (day 5.5 luteal) and pelvic ultrasound were carried out during each cycle to evaluate endometrial function and growth. Uterine fluid was assessed for residual copper levels on the day of biopsy, and copper chloride gel underwent mouse embryos assay assessment for potential embryo toxicity. RESULTS: The copper gel significantly increased endometrial VEGF expression (quantitative polymerase chain reaction), and also increasing endometrial thickness by an average of 2.2 mm compared with matched control cycles. The copper gel did not adversely affect endometrial morphology or maturation (histological dating and molecular receptivity testing), and mouse embryos assay studies showed no evidence of embryo toxicity. Furthermore, uterine cavity flush samples mostly lacked copper, with only negligible amounts present in one sample. CONCLUSION: Applying copper chloride gel to the uterine cavity upregulated endometrial VEGF and significantly increased endometrial thickness and volume. No adverse effects on the endometrium or embryos were observed. Copper chloride gels show promise for treating suboptimal endometrial thickness if the results of this study are confirmed by larger randomized controlled trials.

EP2/EP4 targeting prevents tumor-derived PGE2-mediated immunosuppression in cDC2s.

Tumor-derived prostaglandin E2 (PGE2) impairs anti-tumor immunity by priming suppressive functions on various immune cell types, including dendritic cells (DCs). In this way, tumors mediate DC dysfunction and hamper their anti-tumoral activity. PGE2 is known to modulate DC function via signaling through the E-prostanoid receptor type (EP) 2 and EP4. Preclinical studies have demonstrated the therapeutic value of targeting EP2/4 receptor signaling in DCs. Ongoing phase I clinical trials with EP antagonists have shown immunomodulation in cancer patients. However, the systemic drug administration leads to off-target events and subsequent side-effects. To limit the off-target effects of EP targeting, EP2 and EP4 antagonists were encapsulated in polymeric nanoparticles (NPs). In this study we evaluated the efficacy of EP2/4 specific antagonists encapsulated in NPs to protect cDC2s from suppressive effects of tumor-derived PGE2 in different tumor models. We show that tumor-derived PGE2 signals via EP2/4 to mediate the acquisition of a suppressive phenotype of cDC2s. EP2/4 antagonists encapsulated NPs impaired the conversion of cDC2s towards a suppressive state and inhibited the occurrence of suppressive features such as IL-10 production or the ability to expand Tregs. Importantly, the NPs abolished the transition towards this suppressive state in different tumor models: Melanoma-conditioned media, ascites fluid derived from ovarian cancer patients (2D), and upon coculture with colorectal cancer patient-derived organoids (3D). We propose that targeting the PGE2-EP2/4 axis using NPs can achieve immunomodulation in the immune system of cancer patients, alleviate tumor-derived suppression, and thus facilitate the development of potent anti-tumor immunity in cancer patients.

Leakage of plastics and other debris from landfills to a highly protected lake by wintering gulls.

GENERAL CONTEXT: Gulls ingest plastic and other litter while foraging in open landfills, because organic matter is mixed with other debris. Therefore, gulls are potential biovectors of plastic pollution into natural habitats, especially when they concentrate in wetlands for roosting. NOVELTY: We quantified, for the first time, the flow of plastic and other anthropogenic debris from open landfills to a natural lake via the movement of gulls. We focused on Fuente de Piedra, an inland closed-basin lake in Spain that is internationally important for biodiversity. METHODOLOGY: In 2022, we sampled gull pellets regurgitated in the lake by lesser black-backed gulls Larus fuscus that feed on landfills, as well as their faeces, then characterized and quantified debris particles of ≥0.5 mm. By combining GPS and census data from 2010 to 2022, together with plastic quantification based on FTIR-ATR analysis, we estimated the average annual deposition of plastic and other debris by the wintering gull population into the lake. MAIN RESULTS: 86 % of pellets contained plastics, and 94 % contained other debris such as glass and textiles. Polyethylene (54 %), polypropylene (11.5 %) and polystyrene (11.5 %) were the main plastic polymers. An estimated annual mean of 400 kg of plastics were moved by gulls into the lake. Only 1 % of plastic mass was imported in faeces. DISCUSSION: Incorporating the biovectoring role of birds can provide a more holistic view of the plastic cycle and waste management. Biovectoring is predictable in sites worldwide where gulls and other waterbirds feed in landfills and roost in wetlands. We discuss bird deterrence and other ways of mitigating debris leakage into aquatic ecosystems.

Perceived Quality of Life Is Related to a Healthy Lifestyle and Related Outcomes in Spanish Children and Adolescents: The Physical Activity, Sedentarism, and Obesity in Spanish Study.

BACKGROUND: Maintaining a healthy lifestyle is crucial for safeguarding the well-being and quality of life perception, appropriate growth, and development of children and adolescents, while also mitigating the risk of future adult-onset diseases. OBJECTIVE: To assess associations between perceived quality of life and healthy lifestyle and related outcomes in Spanish children and adolescents. METHODS: Cross-sectional analysis of 8-16-year-old children and adolescents (n = 3534) were included in the nationwide study of Physical Activity, Sedentarism, and Obesity in Spanish Youth (PASOS). Data were collected through (1) questionnaires on health-related quality of life (HRQoL), healthy lifestyle outcomes (dietary intake, physical fitness, sleep, and screen time), and (2) anthropometric measurements for weight status assessment. Data were analysed by logistic regression, using the health-related quality of life (HRQoL) as the grouping variable. RESULTS: Participants with a lower HRQoL were those with a lower adherence to the MedDiet and lower achievement of the recommended daily intake of fruit and vegetables. They were also less likely to follow the recommendations for screen time and sleep (with the exception of the weekend) compared to participants with a higher HRQoL. Participants with a lower HRQoL showed a lower healthy weight status and poorer physical fitness than those with a higher HRQoL. CONCLUSIONS: Healthy eating habits, healthy weight status (normal weight), appropriate sleep time, physical fitness, and limited screen time play a crucial role in the perceived quality of life in children and adolescents.

Increase in Vascular Function Parameters According to Lifestyles in a Spanish Population without Previous Cardiovascular Disease-EVA Follow-Up Study.

The aim of this longitudinal descriptive observational study was to analyze the influence of different lifestyles on arterial stiffness (AS) throughout five years of follow-up and to describe the differences by sex in a Spanish adult population without cardiovascular disease at the start of the study. A random stratified sampling by age and sex was used to obtain 501 subjects included in the initial assessment. No cardiovascular disease was allowed in the subjects. The average age was 55.9 years, and 50.3% were women. A total of 480 subjects were analyzed again five years later. Alcohol and tobacco consumption were collected with standardized questionnaires. Adherence to the Mediterranean diet was assessed with the Mediterranean diet adherence screener (MEDAS) questionnaire. Physical activity was assessed with the short version of the International Physical Activity Questionnaire-Short Form (IPAQ-SF) and sedentary time was assessed with the Marshall Sitting Questionnaire (MSQ). AS was assessed by measuring carotid-femoral pulse wave velocity (cfPWV) and central augmentation index (CAIx) with SphygmoCor System®, and ankle pulse wave velocity (baPWV) and cardio ankle vascular index (CAVI) with Vasera VS-1500®. Increases in vascular function measures per year of follow-up were: cfPWV = 0.228 ± 0.360 m/s, baPWV = 0.186 ± 0.308 m/s, CAVI = 0.041 ± 0.181 m/s, and CAIx = 0.387 ± 2.664 m/s. In multiple regression analysis, positive association was shown between an increase in baPWV and tobacco index (ß = 0.007) and alcohol consumption (ß = 0.005). Negative association was shown between CAVI and Mediterranean diet score (ß = -0.051). In multinomial logistic regression analysis, the OR of tobacco index of subjects with a cfPWV increase >P75 was OR = 1.025 and of subjects classified between P25 and P75 was OR = 1.026 regarding subjects classified with an increase P75 was OR = 1.006 regarding subjects classified with an increase P75, and an OR = 0.841 was found of subjects classified between P25-75 regarding subjects classified with an increase

Assessment of obesity stigma and discrimination among Spanish subjects with a wide weight range: the OBESTIGMA study.

Introduction: This study aims to assess the extent of rejection and instances of stigmatization linked to obesity within the Spanish population, encompassing a diverse spectrum of weights ranging from normal weight to morbid obesity. Additionally, the study seeks to identify the primary factors influencing these experiences and further examines the impact of bariatric surgery on such dynamics. Materials and methods: Multicenter observational study with involving a total of 1,018 participants who were recruited from various Obesity Units. Negatives attitudes towards people with obesity were assessed through three questionnaires: (i) Antifat Attitudes Scale (AFA), (ii) Stigmatizing Situations Inventory (SSI) and (iii) Weight Bias Internalization Scale (WBIS). Subjects were categorized into four groups based on their BMI and history of prior bariatric surgery. Results: The cumulative score across all questionnaires (AFA, SSI and WBIS) exhibited a progressive increase, from participants with normal weight to those with obesity (p < 0.001 for all). Within the AFA questionnaire, males showed more rejection towards people with obesity than women, also perceiving obesity as a disease linked to a lack of willpower (p = 0.004 and p = 0.030, respectively). The overall SSI score was negatively associated with age (r = -0.080, p = 0.011), with young participants encountering more stigmatizing experiences than their adult counterparts. Neither employment status nor educational demonstrated a significant association with any of the questionnaires. Interestingly, patients who underwent lost weight following bariatric surgery did not exhibit improved outcomes. Conclusion: Individuals with obesity demonstrate a heightened level of aversion towards the disease compared to those with normal weight. Concurrently, the incidence of stigmatizing encounters displays a concerning escalation among younger individuals.

The effect of vitrification on blastocyst mitochondrial DNA dynamics and gene expression profiles.

PURPOSE: Does vitrification/warming affect the mitochondrial DNA (mtDNA) content and the gene expression profile of blastocysts? METHODS: Prospective cohort study in which 89 blastocysts were obtained from 50 patients between July 2017 and August 2018. mtDNA was measured in a total of 71 aneuploid blastocysts by means of real-time polymerase chain reaction (RT-PCR). Transcriptomic analysis was performed by RNA sequencing (RNA-seq) in an additional 8 aneuploid blastocysts cultured for 0 h after warming, and 10 aneuploid blastocysts cultured for 4-5 h after warming. RESULTS: A significant decrease in mtDNA content just during the first hour after the warming process in blastocysts was found (P < 0.05). However, mtDNA content experimented a significantly increased along the later culture hours achieving the original mtDNA levels before vitrification after 4-5 h of culture (P < 0.05). Gene expression analysis and functional enrichment analysis revealed that such recovery was accompanied by upregulation of pathways associated with embryo developmental capacity and uterine embryo development. Interestingly, the significant increase in mtDNA content observed in blastocysts just after warming also coincided with the differential expression of several cellular stress response-related pathways, such as apoptosis, DNA damage, humoral immune responses, and cancer. CONCLUSION: To our knowledge, this is the first study demonstrating in humans, a modulation in blastocysts mtDNA content in response to vitrification and warming. These results will be useful in understanding which pathways and mechanisms may be activated in human blastocysts following vitrification and warming before a transfer.

Preoperative renal embolisation in patients with polycystic kidney disease requiring incisional hernia repair after renal transplantation.

In the same way that renal transcatheter arterial embolisation (TAE) has demonstrated its effectiveness and safety compared with nephrectomy of the polycystic kidney at the time of transplantation, we propose that TAE can be a minimally invasive option in the surgical preparation for incisional hernia repair in order to reduce the compressive effect of the polycystic kidney, creating space and ensuring safe hernia repair. The objective of this article is to describe the first case in which TAE is used in advance of incisional hernia secondary to renal transplantation in patients with autosomal dominant polycystic kidney disease.

Utility of anti-GM-CSF antibodies in the diagnosis of pulmonary alveolar proteinosis: a case report.

Introduction: Pulmonary alveolar proteinosis (PAP) is a disease characterized by the accumulation of lipoprotein-aceous material in the alveoli as a consequence of deficient processing of pulmonary surfactant. It is classified into primary, secondary, and congenital forms. Primary PAP (autoimmune origin) is characterized by the presence of antibodies against granulocyte-macrophage colony-stimulating factor (GM-CSF), while secondary PAP is due to multiple causes such as exposure to certain environmental substances. We present a case of a patient with probable mixed PAP, primary and secondary, due to exposure at the patient's workplace. Case presentation: A 35-year-old male patient attends the outpatient clinic of pulmonology due to symptoms of exertional dyspnea for one year. Pulmonary function tests are performed, and the chest X-ray reveals diffuse bilateral lung involvement with a ground-glass pattern. Incision and excision lung biopsy show findings compatible with predominant PAP in the left lower lobe (LLL). Additionally, a positive anti-GM-CSF antibody result is obtained. The patient is treated with bronchoalveolar lavage (BAL) and nebulized sargramostim. The patient shows satisfactory progress. Discussion: The clinical, analytical, radiological, and histological manifestations were compatible with the diagnosis of autoimmune PAP, and there was suspicion of secondary PAP due to exposure to rock wool. The role of the laboratory, in this case, was essential for the diagnostic confirmation of PAP by performing the determination of anti-GM-CSF antibodies.

Characterization of Neospora caninum virulence factors NcGRA7 and NcROP40 in bovine target cells.

Bovine neosporosis is one of the major causes of reproductive failure in cattle worldwide, and differences in virulence between isolates have been widely shown. However, the molecular basis and mechanisms underlying virulence in Neospora caninum are mostly unknown. Recently, we demonstrated the involvement of NcGRA7 and NcROP40 in the virulence of N. caninum in a pregnant murine model using single knockout mutants in these genes generated by CRISR/Cas9 technology. In this study, the role of these proteins was investigated in two in vitro models using bovine target cells: trophoblast (F3 cell line) and monocyte-derived macrophages (BoMØ). The proliferation capacity of the single knockout mutant parasites was compared to the wild-type strain, the Nc-Spain7 isolate, using both cell populations. For the bovine trophoblast, no differences were observed in the growth of the defective parasites compared to the wild-type strain, neither in the proliferation kinetics nor in the competition assay. However, in naïve BoMØ, a significant decrease in the proliferation capacity of the mutant parasites was observed from 48 h pi onwards. Stimulation of BoMØ with IFN-γ showed a similar inhibition of tachyzoite growth in defective and wild-type strains in a dose-dependent manner. Finally, BoMØ infected with knockout parasites showed higher expression levels of TLR3, which is involved in pathogen recognition. These results suggest that NcGRA7 and NcROP40 may be involved in the manipulation of innate immune defense mechanisms against neosporosis and confirm the usefulness of the BoMØ model for the evaluation of N. caninum virulence mechanisms. However, the specific functions of these proteins remain unknown, opening the way for future research.

Cocoa Bean Shell: A By-Product with High Potential for Nutritional and Biotechnological Applications.

Cocoa bean shell (CBS) is one of the main solid wastes derived from the chocolate industry. This residual biomass could be an interesting source of nutrients and bioactive compounds due to its high content in dietary fibres, polyphenols and methylxanthines. Specifically, CBS can be employed as a raw material for the recovery of, for example, antioxidants, antivirals and/or antimicrobials. Additionally, it can be used as a substrate to obtain biofuels (bioethanol or biomethane), as an additive in food processing, as an adsorbent and, even, as a corrosion-inhibiting agent. Together with the research on obtaining and characterising different compounds of interest from CBS, some works have focused on the employment of novel sustainable extraction methods and others on the possible use of the whole CBS or some derived products. This review provides insight into the different alternatives of CBS valorisation, including the most recent innovations, trends and challenges for the biotechnological application of this interesting and underused by-product.

Immunomodulatory, Anti-Inflammatory, and Anti-Cancer Properties of Ginseng: A Pharmacological Update.

Ginseng, a medicinal plant of the genus Panax, boasts a rich historical record of usage that dates back to the Paleolithic period. This botanical is extensively acknowledged and consumed in Eastern countries for its therapeutic properties, and, in Western countries, it is becoming increasingly popular as a remedy for fatigue and asthenia. This review provides an update on current research pertaining to ginseng and its isolated compounds, namely, ginsenosides and polysaccharides. The primary focus is on three crucial pharmacological activities, namely, immunomodulation, anti-inflammatory, and anti-cancer effects. The review encompasses studies on both isolated compounds and various ginseng extracts obtained from the root, leaves, and berries.

Seed Size, Not Dispersal Syndrome, Determines Potential for Spread of Ricefield Weeds by Gulls.

Recent field data suggest that migratory gulls disperse many rice field weeds by gut passage (endozoochory), most of which are dry fruited and widely assumed to have no long-distance dispersal mechanisms, except via human activity. We investigated this mechanism with a feeding experiment, in which seeds of five common rice field weeds (in order of increasing seed size: Juncus bufonius, Cyperus difformis, Polypogon monspeliensis, Amaranthus retroflexus, and the fleshy-fruited Solanum nigrum) were fed to seven individuals of lesser black-backed gulls Larus fuscus held in captivity. We quantified seed survival after collecting faeces at intervals for 33 h after ingestion, then extracting intact seeds and running germination tests, which were also conducted for control seeds. All five species showed high seed survival after gut passage, of >70%. Gut retention times averaged 2-4 h, but maxima exceeded 23 h for all species. Germinability after gut passage was 16-54%, and gut passage accelerated germination in J. bufonius and S. nigrum, but slowed it down in the other species. All species had lower germinability after gut passage compared to control seeds (likely due to stratification prior to the experiment), but the loss of germinability was higher in smaller seeds. There was no evidence that the different dispersal syndromes assigned to the five species (endozoochory, epizoochory or barochory) had any influence on our results. In contrast, mean gut retention time was strongly and positively related to seed size, likely because small seeds pass more quickly from the gizzard into the intestines. Non-classical endozoochory of dry-fruited seeds by waterbirds is a major but overlooked mechanism for potential long-distance dispersal, and more research into this process is likely essential for effective weed management.

Phytochemical Characterization and In Vitro and In Silico Biological Studies from Ferns of Genus Blechnum (Blechnaceae, Polypodiales).

The genus Blechnum represents one of the most ecologically and therapeutically important groups of ferns that grow in tropical, subtropical and temperate regions. In this work, the chemical fingerprint of lyophilized extracts of Blechnum chilense, B. hastatum, B. magellanicum and B. penna-marina species, the determination of their antioxidant activity through ORAC, FRAP and DPPH assays and inhibition of cholinesterase enzymes (AChE and BChE), and an in silico analysis of selected majority compounds on cholinesterase enzymes were identified. Nineteen compounds were recorded for B. chilense, nine in B. hastatum, seventeen in B. magellanicum and seventeen in B. penna-marina by liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry (UHPLC-ESI-QTOF-MS). The content of phenolic compounds, flavonoids, antioxidant activity and enzyme inhibition were variable among species, with best results for B. penna-marina. Molecular docking evidenced low toxicities, significant pharmacokinetic properties, and significant binding affinities of the tested compounds for the AChE and BChE enzymes. These fern species show high diversity of bioactive compounds and represent a promising resource in phytotherapy, especially for their optimal levels of phenolic compounds that support their antioxidant activity.
