Hydrothermal Chemistry of the M(I,II)/PAHA/Anion System

This research encompasses the detailed investigation of the design and synthesis of metal organic framework (MOF) materials involving the M(I,II)/ polyazaheterocycle/anion system in order to expand our understanding of the principles which render the chemistry more controllable and predictable. In addition, this research investigates the development of properties in these classes of compounds. Furthermore, it has been demonstrated that hydrothermal reaction conditions of stoichiometry, pH, and temperature can influence the identity of the products. The structural versatility of the M(I,II)/polyazaheterocycle/anion system for M = Cu(I,II), Co(II), Ni (II), Zn (II), and Cd(II) and where the anion is F-, Cl-, I-, OH-, SO42-, or PO43-, is a reflection of the many structural determinants at play. These include factors such as: (i) the variety of coordination polyhedra available to the metal, (ii) variable modes of coordination associated with the azole(ate) ligands, (iii) the role of functional substituents on the azolate moiety, (iv) the incorporation and coordination preferences of secondary anionic components (Xn- or XOmn-) and (v) the variable incorporation of solvent molecules. The structural chemistry of these materials is quite complex, as evidenced by the range of component substructures observed including a range of chains, layers, frameworks, and embedded metal/azolate clusters. In addition, many of the products exhibited interesting magnetic properties. While a number of recurring structural motifs have been observed, the remarkable array of structures of materials in this study underlines the difficulty in predicting product composition and the challenge in rational design of framework materials. It is anticipated that the continued elaboration of a structural data base for these complex hierarchical materials will evolve into a structural systematic

Prioritization and Planning to Improve Urban Tree Health in the Chicago Region

The Chicago Region Trees Initiative (CRTI) has collected one of the largest data sets on urban forestry in the United States. This data informs where and how CRTI prioritizes its work and capacity building. This data has been incorporated into interactive online resources that communities and neighborhoods can access to help decision makers, landowners, and managers understand where and what to plant, the value of the urban forest, impacts of woody invasive species, heat island challenges, and where opportunities exist for oak ecosystem enhancement. This data helps CRTI and its partners to prioritize action

Cross Sector Partnerships – Development of the Chicago Region Trees Initiative

The Chicago Region Trees Initiative (CRTI) is a partnership of more than 200 organizations across the seven county Chicago metro region. The CRTI believes that trees are critical to our quality of life, and its mission is to ensure that trees are more healthy, abundant, diverse, and equitably distributed to provide needed benefits to all people and communities in the Chicago region. Our key goals are to inspire people to value trees, increase the Chicago region’s tree canopy, reduce threats to trees, and enhance oak ecosystems. The CRTI has built upon the work and programs of others, and the experience of partners to shape the urban forest in the Chicago region by 2050

Cyanobacterial endobionts within a major marine, planktonic, calcifier (Globigerina bulloides, Foraminifera) revealed by 16S rRNA metabarcoding

We investigated the possibility of bacterial symbiosis in Globigerina bulloides, a palaeoceanographically important, planktonic foraminifer. This marine protist is commonly used in micropalaeontological investigations of climatically sensitive subpolar and temperate water masses as well as wind-driven upwelling regions of the world's oceans. G. bulloides is unusual because it lacks the protist algal symbionts that are often found in other spinose species. In addition, it has a large offset in its stable carbon and oxygen isotopic compositions compared to other planktonic foraminifer species, and also that predicted from seawater equilibrium. This is suggestive of novel differences in ecology and life history of G. bulloides, making it a good candidate for investigating the potential for bacterial symbiosis as a contributory factor influencing shell calcification. Such information is essential to evaluate fully the potential response of G. bulloides to ocean acidification and climate change. To investigate possible ecological interactions between G. bulloides and marine bacteria, 18S rRNA gene sequencing, fluorescence microscopy, 16SrRNA gene metabarcoding and transmission electron microscopy (TEM) were performed on individual specimens ofG. bulloides(type IId) collected from two locations in the California Current. Intracellular DNA extracted from fiveG. bulloidesspecimens was subjected to 16S rRNA gene metabarcoding and, remarkably, 37–87 % of all 16S rRNA gene sequences recovered were assigned to operational taxonomic units (OTUs) from the picocyanobacterium Synechococcus. This finding was supported by TEM observations of intact Synechococcus cells in both the cytoplasm and vacuoles of G. bulloides. Their concentrations were up to 4 orders of magnitude greater inside the foraminifera than those reported for the California Current water column and approximately 5 % of the intracellular Synechococcus cells observed were undergoing cell division. This suggests that Synechococcus is an endobiont of G. bulloides type IId, which is the first report of a bacterial endobiont in the planktonic foraminifera. We consider the potential roles of Synechococcus and G. bulloides within the relationship and the need to determine how widespread the association is within the widely distributed G. bulloides morphospecies. The possible influence of Synechococcus respiration on G. bulloides shell geochemistry is also explored

Oral Health and Barriers to Care in Burlington Housing Authority Residents

Background Oral health affects everyone and serves as a model for the long term benefits of establishing preventative health practices early in life. However, children with significant socioeconomic stress or cultural and language barriers to access may have difficulty obtaining oral hygiene information, or developing and maintaining oral health regimens. The Burlington Housing Authority (BHA) provides housing subsidization to low-income families and services many resettled refugee families in Burlington, VT. We recognize some intervention initiatives are already and place, and will evaluate program efficacy and utilization. Ultimately, we seek to understand barriers to the existing programs and recommend strategies to increase utilization, compliance, and education in our target population.https://scholarworks.uvm.edu/comphp_gallery/1273/thumbnail.jp

Understanding Occupational Injury and Substance Use Issues among Workers in the Shellfish and Lobster Industries

In 2022, American lobster (Homarus americanus) and softshell clam (Mya arenaria) harvests contributed $283 million to Downeast Maine’s economy, employing thousands of harvesters. Harvesting is grueling work. Pain from work-related injuries precedes most opioid deaths, and workers in fisheries are disproportionately at risk. Harvesters are typically self-employed and often uninsured or underinsured, complicating access to care. Prior studies have focused on injury risk or drug use among harvesters without revealing how injury, pain and substance use intertwine with cultural, social and regulatory factors. This study examined the socio-ecologically embedded injury/ pain/ substance use process with surveys of harvesters (n=106) and healthcare providers and advocates (n=31) followed by interviews of harvesters (n=13) and providers (n=8). We found that harvesters are extremely prone to injury from myriad causes. Shellfish harvesters were more injury-prone and socially vulnerable than lobster harvesters. Deferral of care, problems with healthcare access, age, lack of cultural competency among healthcare providers, and challenges with financial stability were linked to poor outcomes. Interviewees shared many anecdotes of addiction and overdose stemming from injury. Self-medication with substances other than opioids was also prevalent, indicating widespread pain-related challenges. Participants reported family disruption and incarceration related to substance use disorder, and common comorbidities included hepatitis-C, HIV and organ failure. Consultation with community partners yielded recommendations to support health and keep Maine\u27s fisheries afloat, including community-embedded healthcare services, fisheries policy arrangements that reduce injury risk and incentivize health, financial education for managing boom and bust cycles, and expanded insurance programs

Prediction of winter vitamin D status and requirements in the UK population based on 25(OH) vitamin D half-life and dietary intake data

On a population basis, there is a gradual decline in vitamin D status (plasma 25(OH)D) throughout winter. We developed a mathematical model to predict the population winter plasma 25(OH)D concentration longitudinally, using age-specific values for 25(OH)D expenditure (25(OH)D3t1/2), cross-sectional plasma 25(OH)D concentration and vitamin D intake (VDI) data from older (70+ years; n=492) and younger adults (18-69 years; n=448) participating in the UK National Diet and Nutrition Survey. From this model, the population VDI required to maintain the mean plasma 25(OH)D at a set concentration can be derived. As expected, both predicted and measured population 25(OH)D (mean (95%CI)) progressively declined from September to March (from 51 (40-61) to 38 (36-41)nmol/L (predicted) vs 38 (27-48)nmol/L (measured) in older people and from 59 (54-65) to 34 (31-37)nmol/L (predicted) vs 37 (31-44)nmol/L (measured) in younger people). The predicted and measured mean values closely matched. The predicted VDIs required to maintain mean winter plasma 25(OH)D at 50nmol/L at the population level were 10 (0-20) to 11 (9-14) and 11 (6-16) to 13(11-16)μg/d for older and younger adults, respectively dependent on the month. In conclusion, a prediction model accounting for 25(OH)D3t1/2, VDI and scaling factor for the 25(OH)D response to VDI, closely predicts measured population winter values. Refinements of this model may include specific scaling factors accounting for the 25(OH)D response at different VDIs and as influenced by body composition and specific values for 25(OH)D3 t1/2 dependent on host factors such as kidney function. This model may help to reduce the need for longitudinal measurements

Vitamin D and SARS-Co V-2 virus/COVID-19 disease

Summary for social mediaVitamin D is essential for good health, especially bone and muscle health. Many people have low blood levels of vitamin D, especially in winter or if confined indoors, because summer sunshine is the main source of vitamin D for most people. Government vitamin D intake recommendations for the general population are 400 IU (10 µg) per day for the UK7 and 600 IU (15 µg) per day for the USA (800 IU (20 µg) per day for >70 years) and the EU.9 Taking a daily supplement (400 IU /day (10 µg/day) in the UK) and eating foods that provide vitamin D is particularly important for those self-isolating with limited exposure to sunlight. Vitamin D intakes greater than the upper limit of 4000 IU (100 µg) per day may be harmful and should be avoided unless under personal medical/clinical advice by a qualified health professional
