    Abstract Urban tree canopies provide manifold benefits, such as: improved air quality, moderated temperatures, reduced storm water runoff, increased property value, reduced crime, improved visual aesthetics, and reduced health problems. Socioeconomically disadvantaged neighborhoods often have many fewer trees than other neighborhoods. This mixed methods case study explored approaches to expand the participatory process in tree stewardship with residents from a socioeconomically disadvantaged neighborhood in Washington, D.C. As a first step, we used semi-structured interviews to elicit residents’ experiences regarding nature and trees. We then built public-private partnerships to strategically convene multi-year tree planting efforts. We additionally performed targeted community outreach, developed a Tree Planting Challenge, and supported mural art to draw attention to the urban tree canopy. Ultimately, the mixed approaches resulted in more than 660 commitments to having free trees planted on properties in a matter of 12 months. We review these findings and discuss implications for future research into collective efficacy-building for a range of sustainability issues.

    Abstract Background: Current medicines do not provide sufficient seizure control for nearly one-third of patients with epilepsy. New options are needed to address this treatment gap. We recently found that the atypical amino acid d-leucine protected against acutely-induced seizures in mice, but its effect in chronic seizures has not been explored. We hypothesized that d-leucine would protect against spontaneous recurrent seizures. We also investigated whether mice lacking a previously-described d-leucine receptor (Tas1R2/R3) would be protected against acutely-induced seizures.
    Methods: Male FVB/NJ mice were subjected to kainic acid-induced status epilepticus and monitored by video-electroencephalography (EEG) (surgically implanted electrodes) for 4weeks before, during, and after treatment with d-leucine. Tas1R2/R3 knockout mice and controls underwent the maximal electroshock threshold (MES-T) and 6-Hz tests.
    Results: There was no difference in number of calendar days with seizures or seizure frequency with d-leucine treatment. In an exploratory analysis, mice treated with d-leucine had a lower number of dark cycles with seizures. Tas1R2/R3 knockout mice had elevated seizure thresholds in the MES-T test but not the 6-Hz test.
    Conclusions: d-Leucine treatment was ineffective against chronic seizures after kainic acid-induced status epilepticus, but there was some efficacy during the dark cycle. Because d-leucine is highly concentrated in the pineal gland, these data suggest that d-leucine may be useful as a tool for studying circadian patterns in epilepsy. Deletion of the Tas1R2/R3 receptor protected against seizures in the MES-T test and, therefore, may be a novel target for treating seizures.

    Abstract Approximately half of all vaccines produced annually are wasted because effectivity is dependent on protein structure and heat exposure disrupts the intermolecular interactions needed to maintain the structure. Thus, most vaccines require a temperature-controlled supply chain to minimize waste. A more sustainable technology was developed via the adsorption of invasion plasmid antigen D (IpaD) onto mesoporous silica, improving the thermal stability of this protein-based therapeutic. Seven silicas were characterized to determine the effects of pore diameter, pore volume, and surface area on protein adsorption. The silica-IpaD complex was then heated above the IpaD denaturing temperature and

    Abstract Introduction and aim of the study: Vitamin D deficiency is a common problem in Poland and worldwide. In the light of recent epidemiological studies, D hypovitaminosis causes not only skeletal diseases, but also other chronic diseases such as immunodeficiency or some types of cancer. The proper knowledge can significantly determine pro-health behaviour, therefore the aim of the study was to analyse the knowledge, opinion and social behaviour regarding vitamin D.
    Material and methods: The survey was conducted among 300 Silesian Voivodeship inhabitants (178 women and 122 men) using an anonymous survey containing 40 questions.
    Results: 59% of people were aware of solar radiation, as a main source of vitamin D in the human body. Sea fish, as the main dietary vitamin D source, were known to 58% of respondents. The highest number of indications (67%) had dairy products, which are poor sources of cholecalciferol. 37% of people were aware that even a well-balanced diet was not able to provide the required daily dose of vitamin D. 78% of people in the study group were aware of the calcaemic effect of vitamin D. Only 9% of respondents were aware of the safe amount of daily sun exposure, sufficient for vitamin D synthesis, while 69% indicated periods of time longer than recommended. 76% of the respondents showed a positive attitude to sun exposure. Taking vitamin D supplementation was declared by 45% of the study participants, while a serum 25(OH)D level was tested only by 6.5% of the respondents.
    Conclusions: Insufficient knowledge about the vitamin D sources among the Silesian Voivodeship inhabitants, misconceptions about the possibility to reach adequate blood levels through the diet, and at the same time low consumption of products rich in vitamin D and its supplements, may be the causes of vitamin D deficiencies.

    Abstract We investigated the association between genetic polymorphisms in cytochrome P450 (CYP2R1, CYP24A1, and the CYP3A family) with nonsummer plasma concentrations of vitamin D metabolites (25-hydroxyvitamin D3 (25(OH)D3) and proportion 24,25-dihydroxyvitamin D3 (24,25(OH)2D3)) among healthy individuals of sub-Saharan African and European ancestry, matched on age (within 5 years; n = 188 in each ancestral group), in central suburban Pennsylvania (2006-2009). Vitamin D metabolites were measured using high-performance liquid chromatography with tandem mass spectrometry. Paired multiple regression and adjusted least-squares mean analyses were used to test for associations between genotype and log-transformed metabolite concentrations, adjusted for age, sex, proportion of West-African genetic ancestry, body mass index, oral contraceptive (OC) use, tanning bed use, vitamin D intake, days from summer solstice, time of day of blood draw, and isoforms of the vitamin D receptor (VDR) and vitamin D binding protein. Polymorphisms in CYP2R1, CYP3A43, vitamin D binding protein, and genetic ancestry proportion remained associated with plasma 25(OH)D3 after adjustment. Only CYP3A43 and VDR polymorphisms were associated with proportion 24,25(OH)2D3. Magnitudes of association with 25(OH)D3 were similar for CYP3A43, tanning bed use, and OC use. Significant least-squares mean interactions (CYP2R1/OC use (P = 0.030) and CYP3A43/VDR (P = 0.013)) were identified. A CYP3A43 genotype, previously implicated in cancer, is strongly associated with biomarkers of vitamin D metabolism. Interactive associations should be further investigated.

    Abstract There are no effective treatments for millions of patients with intractable epilepsy. High-fat ketogenic diets may provide significant clinical benefit but are challenging to implement. Low carbohydrate levels appear to be essential for the ketogenic diet to work, but the active ingredients in dietary interventions remain elusive, and a role for ketogenesis has been challenged. A potential antiseizure role of dietary protein or of individual amino acids in the ketogenic diet is understudied. We investigated the two exclusively ketogenic amino acids, L-leucine and L-lysine, and found that only L-leucine potently protects mice when administered prior to the onset of seizures induced by kainic acid injection, but not by inducing ketosis. Unexpectedly, the D-enantiomer of leucine, which is found in trace amounts in the brain, worked as well or better than L-leucine against both kainic acid and 6Hz electroshock-induced seizures. However, unlike L-leucine, D-leucine potently terminated seizures even after the onset of seizure activity. Furthermore, D-leucine, but not L-leucine, reduced long-term potentiation but had no effect on basal synaptic transmission in vitro. In a screen of candidate neuronal receptors, D-leucine failed to compete for binding by cognate ligands, potentially suggesting a novel target. Even at low doses, D-leucine suppressed ongoing seizures at least as effectively as diazepam but without sedative effects. These studies raise the possibility that D-leucine may represent a new class of anti-seizure agents, and that D-leucine may have a previously unknown function in eukaryotes.
