Constraining how the biological pump operated in the past is important for understanding past atmospheric carbon dioxide concentrations and Earth's climate history. However, reconstructing the history of the biological pump requires proxies. Due to their intimate association with biological processes, several bioactive trace metals and their isotopes are potential proxies for past phytoplankton productivity, including iron, zinc, copper, cadmium, molybdenum, barium, nickel, chromium, and silver. Here, we review the oceanic distributions, driving processes, and depositional archives for these nine metals and their isotopes based on GEOTRACES-era datasets. We offer an assessment of the overall maturity of each isotope system to serve as a proxy for diagnosing aspects of past ocean productivity and identify priorities for future research. This assessment reveals that cadmium, barium, nickel, and chromium isotopes offer the most promise as tracers of paleoproductivity, whereas iron, zinc, copper, and molybdenum do not. Too little is known about silver to make a confident determination. Intriguingly, the trace metals that are least sensitive to productivity may be used to track other aspects of ocean chemistry, such as nutrient sources, particle scavenging, organic complexation, and ocean redox state. These complementary sensitivities suggest new opportunities for combining perspectives from multiple proxies that will ultimately enable painting a more complete picture of marine paleoproductivity, biogeochemical cycles, and Earth's climate historyThis contribution grew (and grew) out of a joint workshop between GEOTRACES and Past Global Changes (PAGES) held in Aix-en-Provence in December 2018.

Highlights From the Annual Meeting of the American Epilepsy Society 2022

With more than 6000 attendees between in-person and virtual offerings, the American Epilepsy Society Meeting 2022 in Nashville, felt as busy as in prepandemic times. An ever-growing number of physicians, scientists, and allied health professionals gathered to learn a variety of topics about epilepsy. The program was carefully tailored to meet the needs of professionals with different interests and career stages. This article summarizes the different symposia presented at the meeting. Basic science lectures addressed the primary elements of seizure generation and pathophysiology of epilepsy in different disease states. Scientists congregated to learn about anti-seizure medications, mechanisms of action, and new tools to treat epilepsy including surgery and neurostimulation. Some symposia were also dedicated to discuss epilepsy comorbidities and practical issues regarding epilepsy care. An increasing number of patient advocates discussing their stories were intertwined within scientific activities. Many smaller group sessions targeted more specific topics to encourage member participation, including Special Interest Groups, Investigator, and Skills Workshops. Special lectures included the renown Hoyer and Lombroso, an ILAE/IBE joint session, a spotlight on the impact of Dobbs v. Jackson on reproductive health in epilepsy, and a joint session with the NAEC on coding and reimbursement policies. The hot topics symposium was focused on traumatic brain injury and post-traumatic epilepsy. A balanced collaboration with the industry allowed presentations of the latest pharmaceutical and engineering advances in satellite symposia

Multidomain, Surface Layer-associated Glycoside Hydrolases Contribute to Plant Polysaccharide Degradation byCaldicellulosiruptorSpecies

Frontal view of the east elevation, close view of the lower; The campanile, or bell-tower, of Florence Cathedral was begun shortly after Giotto was elected Master of Works in April 1334. He died in 1337, but a design attributed to him survives (Siena, Mus. Opera Duomo). Only the lowest zone corresponds to the completed tower. Work was continued during the 1340s by Andrea Pisano and finished in the late 1350s by Francesco Talenti, who increased the height of the storeys, thus enhancing the elegance and lightness of the structure; he also added a flat-topped belfry. The campanile is square in plan with octagonal corner buttresses. It is divided into horizontal zones: the lower ones are decorated with reliefs and statues, while the upper and slightly narrower part of the tower is pierced on each of its four sides, first by two storeys of twin, two-light openings and, finally, in its uppermost storey, by a single great tripartite window. The campanile is 84 m high and, like the cathedral, is faced in white, green and pink marble. Source: Grove Art Online; http://www.groveart.com/ (accessed 2/10/2008

High rates of posttraumatic stress symptoms in women living with HIV in Canada

Women living with HIV experience high levels of trauma exposure before and after diagnosis. One of the most challenging outcomes following trauma exposure is posttraumatic stress disorder. Despite high exposure to traumatic events, the presence and contributors to posttraumatic stress disorder symptoms have not been examined in women living with HIV in Canada.CHIWOS is funded by a Canadian Institutes of Health Research (CIHR) Operating Grant (grant #MOP-111041), the CIHR Canadian HIV Trials Network (CTN 262), the Ontario HIV Treatment Network (OHTN), and the Academic Health Science Centres (AHSC) Alternative Funding Plans (AFP) Innovation Fund. The following authors received salary support awards: CIHR Postdoctoral Fellowship (Anne C. Wagner), Clinician Investigator Program at UBC (Denise Jaworsky), Canada Research Chair program (Angela Kaida), Fonds de Recherche Sante QueÂbec and Federation des Omnipracticiens du QueÂbec (Alexandra de Pokomondy). Neora Pick is on the boards of VIIV Healthcare and Gilead Sciences. Alexandra de Pokomandy is a site principal investigator for several VIIV Healthcare HIV trials, is a site co-investigator for Gilead Sciences and Merck HIV trials, and received honoraria for participating on the advisory board for VIIV Healthcare. Mona Loutfy has been a site principal investigator and sub-investigator on Merck, VIIV Healthcare, and Gilead Sciences clinical trials and has been on Advisory Boards for these three pharmaceutical companies.
