RESUMEN

BACKGROUND: The evaluation of gender-affirming facial feminization surgery (FFS) outcomes can be highly subjective, which has resulted in a limited understanding of the social perception of favorable gender and aesthetic facial appearance following FFS. Eye-tracking technology has introduced an objective measure of viewer subconscious gaze. OBJECTIVES: The aim of this study was to use eye-tracking technology to measure attention and perception of surgery-naive cisgender female and feminized transgender faces, based on viewer gender identity. METHODS: Thirty-two participants (18 cisgender and 14 transgender) were enrolled and shown 5 photographs each of surgery-naive cisgender female and feminized transgender faces. Gaze was captured with a Tobii Pro X2-60 eye-tracking device (Tobii, Stockholm, Sweden) and participants rated the gender and aesthetic appearance of each face on Likert-type scales. RESULTS: Total image gaze fixation time did not differ by participant gender identity (6.00 vs 6.04 seconds, P = 0.889); however, transgender participants spent more time evaluating the forehead/brow, buccal/mandibular regions, and chin (P < 0.001). Multivariate regression analysis showed significant associations between viewer gender identity, age, race, and education, and the time spent evaluating gender salient facial features. Feminized faces were rated as more masculine with poorer aesthetic appearance than surgery-naive cisgender female faces; however, there was no significant difference in the distribution of gender appearance ratings assigned to each photograph by cisgender and transgender participants. CONCLUSIONS: These results demonstrate that gender identity influences subconscious attention and gaze on female faces. Nevertheless, differences in gaze distribution did not correspond to subjective rated gender appearance for either surgery-naive cisgender female or feminized transgender faces, further illustrating the complexity of evaluating social perception of favorable FFS outcomes.

RESUMEN

Breast cancer incidence and metastasis in postmenopausal women are known to associate with obesity, but the molecular mechanisms behind this association are largely unknown. We investigated the effect of adipokine resistin on epithelial to mesenchymal transition (EMT) and stemness in breast cancer cells in vitro. Previous reports demonstrated that the inflammatory actions of resistin are mediated by the adenylyl cyclase-associated protein 1 (CAP1), which serves as its receptor. As a model for our study, we used MCF-7 and MDA-MB-231 breast cancer and MCF-10A breast epithelial cells. We showed that in MCF-7 cells resistin increases the migration of MCF-7 and MDA-MB-231 cells and induces the formation of cellular protrusions through reorganization of F-actin filaments. Resistin upregulated the expression of mesenchymal markers involved in EMT (SNAIL, SLUG, ZEB1, TWIST1, fibronectin, and vimentin), and downregulated those of epithelial markers (E-cadherin and claudin-1). Resistin also potentiated the nuclear translocation of SNAIL protein, indicating initiation of EMT reprogramming. We further induced EMT in non-carcinogenic breast epithelial MCF-10A cells demonstrating that the effects of resistin on EMT were not breast cancer cell specific. In order to assess whether resistin-induced EMT depends on CAP1, we used siRNA approach to silence CAP1 gene in MCF-7 cells. Results demonstrated that when CAP1 was silenced, the induction of SNAIL, ZEB1 and vimentin expression by resistin as well as SNAIL and ZEB1 nuclear translocation, were abolished. Additionally, CAP1 silencing resulted in a suppression of MCF-7 cells migration. We performed quantitative PCR array profiling the expression of 84 genes related to cancer stem cells (CSC), pluripotency and metastasis and selected a set of genes (ALDH1A1, ITGA4, LIN28B, SMO, KLF17, PTPRC, PROM1, SIRT1, and PECAM1) that were modulated by resistin. Further experiments demonstrated that the effect of resistin on the expression of some of these genes (PROM1, PTPRC, KLF17, SIRT1, and PECAM1) was also dependent on CAP1. Our results demonstrate that resistin promotes the metastatic potential of breast cancer cells by inducing EMT and stemness and some of these effects are mediated by CAP1.

RESUMEN

Eribulin is active and safe in heavily pre-treated metastatic breast cancer patients. Few safety data have been published in third line. We aimed to report the specific safety profile on third line beyond taxanes and anthracyclines in advanced breast cancer (ABC). A multicenter phase II, prospective study was conducted in anthracyclines and taxanes pre-treated HER2-negative ABC, programmed to receive eribulin as third-line chemotherapy. Adverse events (AEs) were assessed and classified according to CTCAE. In addition, efficacy, in terms of overall survival (OS) and progression-free survival (PFS), and the dynamics of circulating tumor cells (CTCs) during treatment were assessed. 59 patients fulfilled the criteria. All but one showed AEs with a cumulative number of 598 AEs. The most frequent grade 3/4 drug-related AEs were neutropenia (1.7%), febrile neutropenia (0.5%), leukopenia (0.5%), alopecia (0.5%), asthenia (0.3%), elevated gamma glutamyl transferase levels (0.2%), and respiratory tract infection (0.2%). Median PFS was 4 months (95% CI 3.1-5.9) and median OS was 13.6 months (11.8-not reached). The mean number of CTCs in peripheral blood was significantly reduced from baseline to cycle 2 (16.8 vs 5.4 CTCs; P < 0.001). Median OS was significantly longer in <5 baseline CTC patients compared to ≥5 baseline CTC patients (13.1 months [95% CI: 11.8-not reached] vs 12.5 months [95% CI: 7.6-not reached]; P = 0.045). A significant correlation (P = 0.0129) was observed between CTC levels at cycle 2 and death when CTCs were analyzed using cox regression. Eribulin chemotherapy is effective and safe as third line in advanced HER2-negative breast cancer. CTC levels correlate with overall survival.

RESUMEN

BACKGROUND: The incidence of differentiated thyroid carcinoma (DTC) in Cuba is low and the contribution of host genetic factors to DTC in this population has not been investigated so far. Our goal was to assess the role of known risk polymorphisms in DTC cases living in Havana. We genotyped five polymorphisms located at the DTC susceptibility loci on chromosome 14q13.3 near NK2 homeobox 1 (NKX2-1), on chromosome 9q22.33 near Forkhead factor E1 (FOXE1) and within the DNA repair gene Ataxia-Telangiectasia Mutated (ATM) in 203 cases and 212 age- and sex- matched controls. Potential interactions between these polymorphisms and other DTC risk factors such as body surface area, body mass index, size, ethnicity, and, for women, the parity were also examined. RESULTS: Significant association with DTC risk was found for rs944289 near NKX2-1 (OR per A allele = 1.6, 95% CI: 1.2-2.1), and three polymorphisms near or within FOXE1, namely rs965513 (OR per A allele = 1.7, 95% CI: 1.2-2.3), rs1867277 in the promoter region of the gene (OR per A allele = 1.5, 95% CI: 1.1-1.9) and the poly-alanine tract expansion polymorphism rs71369530 (OR per Long Allele = 1.8, 95% CI: 1.3-2.5), only the 2 latter remaining significant when correcting for multiple tests. Overall, no association between DTC and the coding SNP D1853N (rs1801516) in ATM (OR per A Allele = 1.1, 95% CI: 0.7-1.7) was seen. Nevertheless women who had 2 or more pregnancies had a 3.5-fold increase in risk of DTC if they carried the A allele (OR 3.5, 95% CI: 3.2-9.8) as compared to 0.8 (OR 0.8, 95% CI: 0.4-1.6) in those who had fewer than 2. CONCLUSIONS: We confirmed in the Cuban population the role of the loci previously associated with DTC susceptibility in European and Japanese populations through genome-wide association studies. Our results on ATM and the number of pregnancies raise interesting questions on the mechanisms by which oestrogens, or other hormones, alter the DNA damage response and DNA repair through the regulation of key effector proteins such as ATM. Due to the small size of our study and to multiple tests, all these results warrant further investigation.

RESUMEN

OBJECTIVE: The objectives of this study were to investigate if referred pain elicited by active trigger points (TrPs) reproduced the symptoms in individuals with painful knee osteoarthritis (OA) and to determine the relationship between the presence of active TrPs, intensity of ongoing pain, function, quality of life, and sleep quality in individuals with painful knee OA. METHODS: Eighteen women with bilateral painful knee OA, aged 79 to 90 years, and 18 matched controls participated. Muscle TrPs were bilaterally explored in several muscles of the lower extremity. Trigger points were considered active if the elicited referred pain reproduced knee symptoms, and TrPs were considered latent if the elicited pain did not reproduce symptoms. Pain was collected with a numerical pain rate scale (0-10), function was assessed with Western Ontario and McMaster Universities, quality of life was assessed with the Medical Outcomes Study Short Form 36 questionnaire, and sleep quality was determined with the Pittsburgh Sleep Quality Index. RESULTS: Women with knee OA exhibited a greater number of active TrPs (mean, 1 ± 1; P < .001) but similar number of latent TrPs (mean, 4 ± 2) than healthy women (mean, 4 ± 3; P = .613). A greater number of active TrPs were associated with higher intensity of ongoing pain (r = 0.605; P = .007). Higher intensity of ongoing knee pain was associated with lower physical function (P < .05). CONCLUSIONS: The referred pain elicited by active TrPs in the lower extremity muscles contributed to pain symptoms in painful knee OA. A higher number of active TrPs was associated with higher intensity of ongoing knee pain.

RESUMEN

Bovine Johne's disease (BJD) or paratuberculosis is caused by Mycobacterium avium spp. paratuberculosis (MAP) and is a worldwide problem among domestic and wild ruminants. While vaccines are available, natural differences in background immunity between breeds within species and between individuals within herds suggest that genetic differences may be able to be exploited in marker-assisted selection as an aid to disease control. The major histocompatibility complex (MHC) is an important component in immune recognition with considerable genetic variability. In this study, associations between the MHC and resistance to BJD were explored in dairy cattle across two herds in which some of the cattle had been vaccinated with Silirum® (n = 540 cows). A BJD susceptible animal was exposed to MAP and became infected, while a resistant animal was exposed but did not become infected. There are different ways to define both exposure and infection, with different levels of stringency, therefore many classifications of the same set of animals are possible and were included in the analysis. The polymorphic regions of major histocompatibility complex class I (MHC I) and class II (MHC II) genes were amplified from the genomic DNA by PCR and sequenced, targeting exons 2 and 3 of the classical and non-classical MHC I genes and exon 2 from the DRB3, DQA1, DQA2 + 3 and DQB MHC II genes. The frequencies of MHC I and MHC II haplotypes and alleles were determined in susceptible and resistant populations. In unvaccinated animals, seven MHC I haplotypes and seven MHC II haplotypes were associated with susceptibility while two MHC I and six MHC II haplotypes were associated with resistance (P < 0.05). In vaccinated animals, two MHC I and three MHC II haplotypes were associated with susceptibility, while one MHC I and two MHC II haplotypes were associated with resistance (P < 0.05). The alleles in significant haplotypes were also identified. Case definitions with higher stringency resulted in fewer animals being included in the analyses, but the power to detect an association was not reduced and there was an increase in strength and consistency of associations. Consistent use of stringent case definitions is likely to improve agreement in future association studies.

RESUMEN

Mycobacterium bovis causes tuberculosis in cattle and when transmitted to humans typically causes extra-pulmonary tuberculosis (EPTB). Bovine tuberculosis (bTB) has a global distribution and is controlled in most countries to protect animal and public health. Recent studies revealed that bTB is established on dairy farms in Fiji where EPTB cases have been reported in people. The aims of this pilot investigation were to look for putative zoonotic TB (EPTB) cases in people and to evaluate practices that might contribute to the persistence and transmission of M. bovis between cattle and to humans. Existing data sets were shared between the Fiji Ministry of Agriculture and Ministry of Health and a questionnaire-based survey was implemented using One Health principles. Statistically significant co-location and close proximity of EPTB cases and bovine TB affected farms were identified. The bTB infection status of farms was significantly associated with unfenced water sources where cattle grazed. Of 247 households, 65 % shared drinking water sources with cattle and 36 % consumed raw milk without boiling, while 62 % of participants reported backyard slaughter of cattle. Several participants reported current symptoms potentially suggestive of TB (chronic cough) but the impact of smoking and history of previous TB treatment could not be evaluated. Farmers had limited understanding of the practices required to prevent bTB at farm level. Further study is recommended and should include an assessment of lifetime EPTB diagnoses, classification of farms based on more recent bTB test data and molecular typing of mycobacterial isolates from humans, cattle and the environment. A targeted awareness and education approach is required to reduce the future risk of zoonotic TB and to help ensure uptake of recommendations and practices aimed at controlling and preventing bTB.

RESUMEN

Introduction: Alpelisib is an orally selective PI3K alpha inhibitor recently available for the treatment of advanced breast cancer. PI3K pathway is an intracellular signaling pathway that plays an important role in regulating glucose metabolism. Hyperglycemia is the most common adverse event associated. Methods: We describe the case of a severe hyperglycemia associated with alpelisib treatment in a patient with metastatic breast cancer and previously near-normal glycemia. We analyze the clinical presentation, PI3K inhibitor pharmacodynamic aspects, its influence in glycemic control and the required treatment approach. Results: An important impairment of glycemic control was observed after initiation of alpelisib. In addition to insulin sensitizers drugs, intensive insulin regimen was necessary. Flash glucose monitoring (FGM) information has been helpful in understanding the pharmacodynamic aspects of alpelisib and insulin titration. Development of hyperglycemia is fast, already observed 24 hours after initiation of therapy. FGM shows severe and persistent hyperglycemia during most of the day, with a significant downward effect in the 4 hours after each daily intake, which evidences the strong but transitory effect of the drug enzyme blockade. C-peptide level is remarkable in accordance with drug pharmacodynamics, consistent with a significant insulin resistance. Conclusions: Glucose monitoring should always be performed in patients treated with alpelisib, especially in patients with diabetes and prediabetes. It is crucial to anticipate in these patients. Any delay can lead to a worsening in metabolic control resulting in the discontinuation or reduction of alpelisib, which would lead to a decrease in its effectiveness, and consequently would deny patients an effective treatment with an impact on survival.

RESUMEN

Control of bovine tuberculosis (bTB) is a priority for animal health, biosecurity, and human health authorities in Fiji as evident from the long-term funding of the Bovine Brucellosis and Tuberculosis Eradication and Control program (BTEC) and notable improvements to the program described in this paper. To evaluate the performance of the Fiji BTEC program from 2015 to 2020, all available bTB data for cattle were analyzed. Data sources included BTEC bTB testing records, abattoir records and laboratory records. We integrated all information to quantify the bTB tests applied, bTB positive farms and animals, meat inspection and laboratory findings. Test coverage was highest among dairy cattle in Central Division (~73%), where bTB was highly prevalent with 7.8% of dairy cattle and 61.7% of dairy farms found to be positive between 2015 and 2020. There was no visible downward trend in the apparent prevalence of bTB over the 6-year period. During 2019 and 2020, only 21.3% (51/239) of the tested dairy farms maintained their clear status, another 8.4% (20/239) reverted to infected status after 1 year or more of being bTB clear, and most farms remained infected during these 2 years. Factors observed to be contributing to this situation were persistent infections, related in part to the significant number of untested animals, uncontrolled animal movements, and larger farm size. Similar to other developing countries, bTB remains a serious concern and further strengthening of the program targeting the main contributors to bTB persistence, along with maintenance of a comprehensive reporting and traceability system, industry awareness and government support are needed. Control of bTB in Fiji is a long-term objective that must have multiple stakeholder engagement and regular review to measure success.

RESUMEN

BACKGROUND: Of the primary procedures associated with facial gender confirmation surgery, those involving the mentomandibular complex have received the least attention in the literature. METHODS: The authors present their experience with 837 trans feminine patients operated on for facial gender confirmation surgery who underwent mandibular bone contouring procedures, including bone contouring, chin and mandibular body and angle ostectomies, and osteotomies to reposition the chin. The authors describe the surgical techniques and materials used, and present a customized lower border-supported cutting guide designed by their team and used with 205 patients. A femininity perception score was calculated preoperatively and 12 months postoperatively, and satisfaction with the results was measured 12 months postoperatively. RESULTS: The postoperative follow-up ranged from 12 to 110 months. The mean femininity perception score increased from 47.86 preoperatively to 76.41 at 12 months postoperatively (p < 0.001). No emergency surgical operations were required. In no case was there any permanent damage to the mental or inferior dental nerve. The reoperation percentage because of problems detected during the postoperative period was 2.63 percent (22 patients). CONCLUSIONS: With facial gender confirmation surgery of the jawline and chin, it is possible to modify the transverse and vertical components of the jaw; soften the gonial angles; change the format, bone volume, and position of the chin; and harmonize the entire mandibular line. The facial feminization achieved high satisfaction scores regarding the results and feminine gender appearance 12 months after surgery. The future of mandibular bone contouring techniques includes planning with virtual software and surgical support with patient-specific cutting guides.

RESUMEN

Importance: Three-dimensional planning software is not standardized in facial gender-affirming surgery. Objective: To develop and validate surgical planning software to create cutting guides to contour the lower jaw border. Design, Setting, and Participants: A 3-year prospective case series study done in three phases: software development, validation, and surgical guide application. Ethics committee approval was obtained to enroll the patients (Clinical Research Ethics Committee, Hospital Costa del Sol, Marbella, Spain). Main Outcomes and Measures: Validation phase: degree of agreement between the planned and obtained results, modification of cephalometric parameters, and surgical times. Application phase: surgical technique description, complications, and patient-reported outcome measures. Results: The degree of agreement between the planned and obtained results was inframillimetric (0.31 ± 0.70 mm). The guides reduced the mandible to within feminine parameters (p < 0.05). Surgical times decreased by 10.96% with chin ostectomies (p < 0.05) and 23.06% with lower jaw border (angle-to-angle) surgeries (p < 0.001). In the application phase, revision surgery was required for 11 patients out of 260 (4.23%). Conclusions and Relevance: The use of cutting guides on the lower jaw border is effective, helps reach standard feminine parameters, and decreases surgical times.

RESUMEN

Purpose of Review: Review work to create and evaluate educational materials that could serve as a primary prevention strategy to help both providers and patients in Panama, Colombia, and the USA reduce disease burden of Toxoplasma infections. Recent Findings: Educational programs had not been evaluated for efficacy in Panama, USA, or Colombia. Summary: Educational programs for high school students, pregnant women, medical students and professionals, scientists, and lay personnel were created. In most settings, short-term effects were evaluated. In Panama, Colombia, and USA, all materials showed short-term utility in transmitting information to learners. These educational materials can serve as a component of larger public health programs to lower disease burden from congenital toxoplasmosis. Future priorities include conducting robust longitudinal studies of whether education correlates with reduced adverse disease outcomes, modifying educational materials as new information regarding region-specific risk factors is discovered, and ensuring materials are widely accessible.

RESUMEN

Purpose of Review: Review building of programs to eliminate Toxoplasma infections. Recent Findings: Morbidity and mortality from toxoplasmosis led to programs in USA, Panama, and Colombia to facilitate understanding, treatment, prevention, and regional resources, incorporating student work. Summary: Studies foundational for building recent, regional approaches/programs are reviewed. Introduction provides an overview/review of programs in Panamá, the United States, and other countries. High prevalence/risk of exposure led to laws mandating testing in gestation, reporting, and development of broad-based teaching materials about Toxoplasma. These were tested for efficacy as learning tools for high-school students, pregnant women, medical students, physicians, scientists, public health officials and general public. Digitized, free, smart phone application effectively taught pregnant women about toxoplasmosis prevention. Perinatal infection care programs, identifying true regional risk factors, and point-of-care gestational screening facilitate prevention and care. When implemented fully across all demographics, such programs present opportunities to save lives, sight, and cognition with considerable spillover benefits for individuals and societies.

RESUMEN

Purpose of Review: Review international efforts to build a global public health initiative focused on toxoplasmosis with spillover benefits to save lives, sight, cognition and motor function benefiting maternal and child health. Recent Findings: Multiple countries' efforts to eliminate toxoplasmosis demonstrate progress and context for this review and new work. Summary: Problems with potential solutions proposed include accessibility of accurate, inexpensive diagnostic testing, pre-natal screening and facilitating tools, missed and delayed neonatal diagnosis, restricted access, high costs, delays in obtaining medicines emergently, delayed insurance pre-approvals and high medicare copays taking considerable physician time and effort, harmful shortcuts being taken in methods to prepare medicines in settings where access is restricted, reluctance to perform ventriculoperitoneal shunts promptly when needed without recognition of potential benefit, access to resources for care, especially for marginalized populations, and limited use of recent advances in management of neurologic and retinal disease which can lead to good outcomes. Supplementary Information: The online version contains supplementary material available at 10.1007/s40124-022-00268-x.

RESUMEN

Purpose of Review: Review comprehensive data on rates of toxoplasmosis in Panama and Colombia. Recent Findings: Samples and data sets from Panama and Colombia, that facilitated estimates regarding seroprevalence of antibodies to Toxoplasma and risk factors, were reviewed. Summary: Screening maps, seroprevalence maps, and risk factor mathematical models were devised based on these data. Studies in Ciudad de Panamá estimated seroprevalence at between 22 and 44%. Consistent relationships were found between higher prevalence rates and factors such as poverty and proximity to water sources. Prenatal screening rates for anti-Toxoplasma antibodies were variable, despite existence of a screening law. Heat maps showed a correlation between proximity to bodies of water and overall Toxoplasma seroprevalence. Spatial epidemiological maps and mathematical models identify specific regions that could most benefit from comprehensive, preventive healthcare campaigns related to congenital toxoplasmosis and Toxoplasma infection.

RESUMEN

In Panama, epidemiological data on congenital toxoplasmosis are limited, making it difficult to understand the scope of clinical manifestations in the population and factors that may increase the risk of infection. This study provides insight into the epidemiological situation of maternal and congenital toxoplasmosis in Panama and contributing information on the burden of this disease in Central America. Blood samples were collected from 2326 pregnant women and used for the detection of anti-T. gondii antibodies. A high seroprevalence (44.41%) was observed for T. gondii infection in pregnant women from different regions of Panama, with an estimated incidence rate of congenital toxoplasmosis of 3.8 cases per 1000 live births. The main risk factors associated with T. gondii infection using bivariate statistical analysis were an elementary level education and maternal age range of 34-45 years. Multivariate statistical analyses revealed that in some regions (San Miguelito, North and West regions), the number of positive cases correlated with the presence of pets, stray dogs and the consumption of poultry. In other regions (East and Metropolitan regions), the absence of pets was considered a protective factor associated with negative cases, while the presence of stray cats and the age range of 25-34 years did not represent any risk in these regions.

RESUMEN

BACKGROUND: No data exist on the prospective outcomes of facial feminization surgery. This study set out to determine the effects of facial feminization surgery on quality-of-life outcomes for gender-diverse patients. METHODS: A prospective, international, multicenter, cohort study with adult gender-diverse patients with gender dysphoria was undertaken. Facial feminization outcome score was calculated preoperatively and postoperatively (1-week to 1-month and >6 months). Photogrammetric cephalometries were measured at the same time points. Self-perceived preoperative masculinity and femininity were recorded. Externally rated gender appearance (scale of 1 to 5, with 1 being most feminine) and general aesthetics (scale of 1 to 10, with 10 being very good) for 10 facial feminization surgery patients were compared with those of five cisgender controls. Univariate linear regression analyses were used to predict outcomes from facial feminization surgery. RESULTS: Sixty-six consecutive patients were enrolled. Patients noted that their brows, jaws, and chins were the most masculine aspects of their faces (54.5 percent, 33.3 percent, and 30.3 percent, respectively). Median facial feminization outcome score increased from 47.2 preoperatively to 80.6 at 6 months or more postoperatively (p < 0.0001). Mean satisfaction was excellent (3.0 at both 1-month and ≥6-month follow-up; p = 0.46). Cephalometric values were significantly more feminine after surgery. Gender appearance was feminine to very feminine (1.83 ± 0.96) and general aesthetics were good (6.09 ± 2.01) but different from those of cisgender women controls (1.25 ± 0.49 and 7.63 ± 1.82, respectively; p < 0.001 for each). CONCLUSION: Facial feminization achieved improved quality of life, feminized cephalometries, feminine gender appearance, good overall aesthetics, and high satisfaction that were present at 1 month and stable at more than 6 months. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMEN

Resistin is an adipokine produced by the white adipocytes and adipose-derived macrophages, which mediates inflammation and insulin resistance Huang et al., 1997 and Renehan et al., 2008 Feb. Here, we provide data on the effect of resistin on epithelial to mesenchymal transition (EMT) in breast cancer cells in vitro. As model systems, we used human MCF-7 (low-metastatic) and MDA-MB-231 (high-metastatic) breast cancer cell lines. To optimize experimental conditions, we treated the cells with various concentrations of resistin (12.5, 25 and 50 ng/ml) for different time intervals (6 and 24 hours), and measured SOCS3 mRNA expression by using qRT-PCR analysis. Further, we used qRT-PCR and Western blot analyses to measure the expression of various epithelial (E-cadherin, claudin-1) and mesenchymal (SNAIL, SLUG, ZEB1, TWIST1, fibronectin, and vimentin) markers after resistin treatment. This data article is part of a study Avtanski et al., 2019 May, where detailed interpretation and discussion can be found.

RESUMEN

Croton reflexifolius H. B. K (Euphorbiaceae) is a very common medicinal plant in the Huastecan region of Mexico that, according to local folk medicine, is considered useful in the treatment of gastritis and gastric ulcer. We have aimed to test the validity of this practice by using the experimental model of an ethanol-induced gastric ulcer in male Wistar rats. The results showed that C. reflexifolius had gastroprotector activity, that the hexane extract had the highest protective activity (64.38+/-7.72%), and that polyalthic acid isolated from this extract was the main active gastroprotector agent. Rats treated orally with polyalthic acid showed a gastroprotective effect similar to that elicited by carbenoxolone. As with carbenoxolone, the effect elicited by polyalthic acid was attenuated by pretreatment with either N(G)-nitro-L-arginine methyl ester (70 mgkg(-1), i.p.), a nitric oxide (NO) synthase inhibitor, or N-ethylmaleimide (10 mgkg(-1), s.c.), a blocker of sulfhydryl groups. This suggested that the gastroprotective mechanism of this diterpenoid involved the participation of both NO and endogenous sulfhydryl groups. Contrary to carbenoxolone, the gastroprotective effect of polyalthic acid was not affected by the inhibition of prostaglandin synthesis with indometacin (10 mgkg(-1), s. c.). In conclusion, Croton reflexifolius contains compounds with gastroprotector activity. Polyalthic acid, which was isolated from this plant, was the main compound with gastroprotector activity, having effectiveness similar to that found with the use of carbenoxolone. Whereas NO and sulfhydryl groups were involved in the mechanisms of gastroprotective action of polyalthic acid, prostaglandins were not.

RESUMEN

Toxoplasmosis is a worldwide zoonotic disease but information regarding domestic animals in Central America is scarce and fragmented. The aim of this study was to determine the seroprevalence of Toxoplasma gondii in domestic cats and dogs in different metropolitan regions of Panama. A total of 576 samples were collected; sera from 120 cats and 456 dogs were tested using a commercial indirect enzyme-linked immunosorbent assay (ELISA). The overall seroprevalence of IgG antibodies was 30.73%. There is high seroprevalence of T. gondii in cats and dogs in the metropolitan regions around the Panama Canal; however, differences between these species were not significant. Statistical analysis indicated that there are relevant variables, such as the age of animals, with a direct positive relationship with seroprevalence. None of the variables related to animal welfare (veterinary attention provided, type of dwelling, and access to green areas and drinking water) were associated with seropositivity.
