Removal processes and estrogenic activity of bisphenol—A and triclosan using microalgae

\ua9 2024 The AuthorsThis study aimed to evaluate the effect of microalgal photoautotrophic treatment on estrogenic activity (EA) and removal process of two emerging contaminants (ECs), bisphenol-A (BPA) and triclosan (TCS), in synthetic wastewater (SWW). The concentration used for BPA (17 mg/L) and TCS (325 μg/L) is the median effective concentration (EC50). Two conditions were evaluated, using a microalgae inoculum of ≈300 and ≈500 mg TSS/L (Total Suspended Solids per liter). For BPA, biodegradation was found to be the removal process contributing to the highest percentage removal, reaching >40 % for both initial microalgae inoculum (≈300 and ≈500 mg TSS/L). For TCS, the highest removal process was photodegradation, with >28 % (sum of direct and indirect removal). However, for TCS it was observed that for TSS ≈ 500 mg/L TSS, sorption (adsorption and absorption) increased by ≈17 % with respect to that determined for TSS ≈ 300 mg/L. Microalgae photoautotrophic treatment, using ≈500 mg TSS/L, resulted in a reduction of EA for TCS (by 33 %); but a 1.13-fold increase of EA for BPA. No EA effect of BPA and TCS was observed at ≈300 mg TSS/L. Both treatments resulted in a removal of >95 % of BPA and ≈86 % of TCS. For direct photodegradation, removals of both BPA and TCS were quantified as 3.8 % and 14.4 %, respectively. However, an increase in EA was observed for both ECs (1.79-fold for BPA and 1.23-fold for TCS). Indirect photodegradation resulted in removals of 26.2 % and 14.1 %, respectively. Additionally, EA showed a 2.4-fold increase for BPA, whilst a 17.99 % decrease was observed for TCS. In conclusion, no linear correlation was observed between EA and EC removals. Microalgae photoautotrophic treatment resulted in high removal efficiencies of TCS and BPA, as well as a decreased EA of TCS

Nutritional Assessment of Plant-Based Meat Alternatives: A Comparison of Nutritional Information of Plant-Based Meat Alternatives in Spanish Supermarkets

Since the classification of processed meat as carcinogenic by the International Agency for Research on Cancer (IARC) in 2015, an increase in consumption of plant-based meat alternatives (PBMAs) has been observed worldwide. This occurs in a context characterized by concern for health, animal welfare, and sustainability; however, evidence of their nutritional quality is still limited. Therefore, our objective was to evaluate the nutritional profile and processing degree of PBMAs available in Spain. In 2020, products from seven Spanish supermarkets were analyzed for their nutritional content and ingredients. Of the 148 products, the majority were low in sugars but moderate in carbohydrates, total and saturated fat, and high in salt. The main vegetable protein sources were soy (91/148) and wheat gluten (42/148). Comparatively, 43/148 contained animal protein, the most common being egg. Overall, PBMAs had a long list of ingredients and additives, and they were classified as ultra-processed foods (UPFs) according to the NOVA system. This study shows that the PBMAs available in Spanish supermarkets have a variable nutritional composition within and between categories. Further research is needed to determine if replacing meat with these UPFs could be a good alternative towards healthier and more sustainable dietary patterns

Efficacy of lavender essential oil in reducing stress, insomnia, and anxiety in pregnant women: A systematic review

Background/Objectives: During pregnancy, women can experience stress, anxiety, and insomnia, which affect their health and wellbeing. Since many conventional medications are contraindicated for pregnant women, there is a need to find alternative therapies for alleviating their discomfort. Lavender essential oil (EO) is recognized for its calming and relaxing properties; therefore, our goal was to review current knowledge of lavender EO use to reduce anxiety and stress as well as to improve sleep quality in pregnant women. Methods: We conducted a comprehensive literature search in 11 databases that included clinical trials published between 2000 and 2022. Results: Of the 251 articles found, only 6, comprising a total of 413 participants that used lavender EO during the second or third trimester of pregnancy, met the inclusion/exclusion criteria. One trial measured sleep quality, one measured anxiety, two measured both anxiety and stress, and two measured only stress. All studies reported significant (at least p < 0.05) improvement in the respective conditions and no adverse effects. Conclusions: The results obtained suggest that although the use of lavender EO during pregnancy has shown to have certain efficacy, given the small number of participants and lack of strong scientific literature, more studies are needed to provide further evidence on this topic.info:eu-repo/semantics/publishedVersio

A web platform for collaborative semi-automatic OCR Post-processing

Digital Humanities researchers often make use of software that helps them in the task of finding non-trivial relationships among characters in historical text. Usually, the source texts that contain such information come from OCR acquired volumes, carrying high amounts of errors within them. This work explains the development of a web platform for the task of OCR post-processing and ground-truth generation. This platform employs machine learning to predict the correct texts accurately from OCR noisy strings. The method used for this task involves transformers for character-based denoising language models. An active learning workflow is proposed, as the users can feed their corrections to the platform, generating new annotated data for re-training the underlying machine learning correction models.Fil: Mechaca, Ana Lidia.

Patient Navigation Services in the Rio Grande Valley: Impacts on Clinicians, Students, and Patients

Purpose: Health professions students of the UTRGV AHEC Scholars Program sought to improve coordination of care and reduce barriers to care recommendations for patients of the UTHealthRGV AHEC clinics. We enacted a student-run multidisciplinary health care system navigation intervention, to address health disparities experienced by residents of colonias in the RGV. Description: Health professions students voluntarily signed up to become “health care system navigators” (HCSNs) as part of a community-engagement activity sponsored by the AHEC Scholars Program. Students received informal training from AHEC staff in the use of the clinic EMR related to identifying patient contact information, documenting patient tele-encounters, and messaging clinic staff. Student navigators interacted via phone with clinician-identified at-risk patients on a regular basis to discuss care recommendations, care progress, and any barriers present in addressing recommendations. Using a student-created community resource directory, navigators connected patients to needed resources and services according to their identified care recommendations and barriers to care. Students met virtually on a weekly basis with clinic providers of AHEC clinics to discuss patient care updates, concerns, and questions. To determine initiative feasibility and effectiveness, three stakeholder groups were surveyed: clinicians, HCSNs, and patients who completed their use of patient navigation services. Each stakeholder group was surveyed monthly for the first three months of program implementation to account for possible addition of members and/or a shift in opinion over time. Survey results revealed uniformly positive feedback from clinicians, HCSNs, and patients. Partners: The AHEC Scholars Program and its community engagement activities, including the HCSN initiative, are financially supported by UTRGV SOM and HRSA. The AHEC Clinic staff at the San Carlos, Bob Clark, and La Victoria locations facilitated clinician and patient interactions with HCSNs. Looking Ahead: Standardized communication procedures and formal HCSN trainings are areas for refinement as the program matures. Stakeholder feedback suggests that the HCSN intervention is a promising and acceptable link between patients, providers, and community resources to address barriers to care and to instill the importance of addressing social determinants of health for health professional trainees. Expansion of this pilot program to other UTHealthRGV clinics awaits future implementation

Morris water maze overtraining increases the density of thorny excrescences in the basal dendrites of CA3 pyramidal neurons

The hippocampus plays a fundamental role in spatial learning and memory. Dentate gyrus (DG) granular neurons project mainly to proximal apical dendrites of neurons in the CA3 stratum lucidum and also, to some extent, to the basal dendrites of CA3 pyramidal cells in the stratum oriens. The terminal specializations of DG neurons are the mossy fibers (MF), and these huge axon terminals show expansion in the CA3 stratum oriens after the animals undergo overtraining in the Morris Water Maze task (MWM). However, to our knowledge there are no reports regarding the possible changes in density of post-synaptic targets of these terminals in the basal dendrites of CA3 neurons after overtraining in the MWM. The purpose of this work was to study the density of thorny excrescences (TE) and other dendritic spine types (stubby, thin, and mushroom) in the CA3 stratum oriens in animals overtrained in the MWM for three consecutive days and in animals trained for only one day. Seven days after MWM training, the animals were sacrificed, and their brains removed and processed for rapid Golgi staining to visualize the different types of dendritic protrusions. Our results revealed that the relative quantity of stubby, thin, and mushroom dendritic spines did not change, regardless of amount of training. However, a significant increase in the density of TE was detected in the overtrained animals. These results strongly suggest that spatial water maze overtraining induces an increased density of MF–TE connections, which might be functionally relevant for long-term spatial memory formation.Fil: Gómez Padilla, Eurídice.
