The Effects of Dissolved and Suspended Solids on Freshwater Meiofauna

Meiofauna include small-sized animals (\u3c 1mm) distributed in all aquatic ecosystems on Earth, where they play fundamental trophic and ecological roles. The biodiversity of marine meiofauna and its links with anthropogenic activities is routinely investigated, however, freshwater communities are less known. This is particularly true for the Southeastern United States, which is greatly investigated and elected a hotspot of biodiversity for larger species but very little is known about the meiofauna. The purpose of this research is to reveal the biodiversity of meiofauna from the Tennessee River and test for potential correlations with anthropogenic activities. As a proxy for pollution, dissolved and suspended solids were considered in this study. The research hypothesis is that meiofaunal biodiversity would be affected by possible changes of dissolved and suspended solids in the water column. Possible mechanisms causing biodiversity shifts could be ascribed to osmotic stresses of animals to cope with variation in dissolved solids or, more indirectly, because different sunlight penetration caused by suspended solids would affect primary production. To test the hypothesis, water samples were collected from nine stations located along the Tennessee River in Hamilton County. Each station was visited three times, and, during each visit, environmental parameters (including dissolved and suspended solids) were measured. Meiofauna biodiversity (estimated as richness, community composition, and phylogenetic diversity) was revealed using a metagenomic approach. Statistical analyses were applied to test for possible correlations between the biodiversity estimates and the measured environmental parameters. Results show a high biodiversity of meiofauna with more than 200 amplicon sequence variants distributed across 10 metazoan phyla. Environmental conditions are highly variable among stations and statistical analyses show that while both dissolved solids (TDS) and turbidity (suspended solids, NTU) did not significantly affect meiofauna biodiversity in the collected samples, various other water and sediment metrics were found to be significant predictors of meiofauna biodiversity. In conclusion, the results of this project not only reveal for the first time the meiofauna biodiversity from the Tennessee River, but also suggest that meiofauna could be used as a bioindicator for several anthropogenic activities in freshwater ecosystems

Socialization to interdisciplinary: faculty and student perspectives

Interdisciplinary research and education are a growing emphasis in United States institutions of higher education but relatively little is known about the doctoral students engaged in these atypical programs. The purpose of this study was to understand the socialization process of 18 students involved in a large-scale, federally funded, interdisciplinary research project focused on sustainability at one university. Using Weidman, Twale, and Stein’s framework of graduate student socialization, themes emerged related to (a) their distinctive characteristics and cultures, (b) the learning process, (c) balance, (d) uncertainty, and (d) support. Recommendations for policy and practice are included

First report of meiofauna biodiversity from the Tennessee River

Small-sized (\u3c 1mm) invertebrates, commonly known as meiofauna, are abundant and ubiquitous in all aquatic ecosystems, performing key functions such as nutrient cycling and sediment stability. Yet, their unexplored diversity and response to disturbances limit our capacity to understand, mitigate, and remediate the consequences of pollution and environmental changes. The biodiversity of meiofauna is largely overlooked especially in freshwater habitats. For example, the Tennessee River hosts more aquatic species than any other region in North America and contains one of the most diverse aquatic ecosystems in the world, however, little is known about its meiofaunal biodiversity. This work includes results obtained between 2019 and 2021 thanks to the contribution of research students working in Leasi’s lab and students enrolled in the Meiofauna Biodiversity class. An integrated morphological and molecular approach revealed the presence of over 200 meiofaunal species distributed across 10 phyla. Results support that the Tennessee River could be a hotspot of biodiversity for small-sized animals as well. Future works will focus on understanding how anthropogenic inputs affect meiofauna biodiversity in this important ecosystem

Personalized rTMS for Depression: A Review

Personalized treatments are gaining momentum across all fields of medicine. Precision medicine can be applied to neuromodulatory techniques, where focused brain stimulation treatments such as repetitive transcranial magnetic stimulation (rTMS) are used to modulate brain circuits and alleviate clinical symptoms. rTMS is well-tolerated and clinically effective for treatment-resistant depression (TRD) and other neuropsychiatric disorders. However, despite its wide stimulation parameter space (location, angle, pattern, frequency, and intensity can be adjusted), rTMS is currently applied in a one-size-fits-all manner, potentially contributing to its suboptimal clinical response (~50%). In this review, we examine components of rTMS that can be optimized to account for inter-individual variability in neural function and anatomy. We discuss current treatment options for TRD, the neural mechanisms thought to underlie treatment, differences in FDA-cleared devices, targeting strategies, stimulation parameter selection, and adaptive closed-loop rTMS to improve treatment outcomes. We suggest that better understanding of the wide and modifiable parameter space of rTMS will greatly improve clinical outcome

Direct Evidence for Octupole Deformation in 146^{146}Ba and the Origin of Large E1E1 Moment Variations in Reflection-Asymmetric Nuclei

Despite the more than one order of magnitude difference between the measured dipole moments in $^{144}$Ba and $^{146}$Ba, the strength of the octupole correlations in $^{146}$Ba are found to be as strong as those in $^{144}$Ba with a similarly large value of $B(E3;3^- \rightarrow 0^+)$ determined as 48($^{+21}_{-29}$) W.u. The new results not only establish unambiguously the presence of a region of octupole deformation centered on these neutron-rich Ba isotopes, but also manifest the dependence of the electric dipole moments on the occupancy of different neutron orbitals in nuclei with enhanced octupole strength, as revealed by fully microscopic calculations.Comment: 6 pages, 5 figures, accepted for publication in Phys.

Gamma Ray Line Constraints on Effective Theories of Dark Matter

A monochromatic gamma ray line results when dark matter particles in the galactic halo annihilate to produce a two body final state which includes a photon. Such a signal is very distinctive from astrophysical backgrounds, and thus represents an incisive probe of theories of dark matter. We compare the recent null results of searches for gamma ray lines in the galactic center and other regions of the sky with the predictions of effective theories describing the interactions of dark matter particles with the Standard Model. We find that the null results of these searches provide constraints on the nature of dark matter interactions with ordinary matter which are complementary to constraints from other observables, and stronger than collider constraints in some cases.Comment: 20 pages, 9 figure

Well-being Content Inclusion in Pharmacy Education Across the United States and Canada

Objective. To describe the landscape of well-being content inclusion across schools and colleges of pharmacy in the United States and Canada through identification of content implementation, incorporation, and assessment. Methods. A cross-sectional survey was distributed to all accredited schools and colleges of pharmacy in the United States (n=143) and Canada (n=10). Survey questions included curricular and cocurricular timing, frequency, assessment strategies, and support for well-being initiatives, using a framework of eight dimensions (pillars) of wellness to categorize content. Results. Descriptive data analyses were applied to 99 completed surveys (65%), 89 (62%) in the United States and 10 (100%) in Canada. Well-being content was most prevalent within the cocurricular realm and incorporated into didactic and elective more than experiential curricula. The most content came from intellectual, emotional, and physical pillars, and the least content came from financial, spiritual, and environmental pillars. Less than 50% of schools and colleges of pharmacy include well-being within their strategic plans or core values. Funding is primarily at the level of the university (59%) or the school or college of pharmacy (59%). Almost half of respondents reported inclusion of some assessment, with a need for more training, expertise, and standardization. Conclusion. Survey results revealed a wide range of implementation and assessment of well-being programs across the United States and Canada. These results provide a reference point for the state of well-being programs that can serve as a call to action and research across the Academy

The Tryptophan Hydroxylase Inhibitor LX1031 Shows Clinical Benefit in Patients With Nonconstipating Irritable Bowel Syndrome

Serotonin (5-hydroxytryptamine [5-HT]) has an important role in gastrointestinal function. LX1031 is an oral, locally acting, small molecule inhibitor of tryptophan hydroxylase (TPH). Local inhibition of TPH in the gastrointestinal tract might reduce mucosal production of serotonin (5-HT) and be used to treat patients with nonconstipating irritable bowel syndrome (IBS)
