The Eating with Ease Program Improved Veterinary Medical Students' Perceived Ability to Buy, Cook, and Eat Healthy Foods.

College students are challenged to consume healthy diets, and veterinary medical students may also have difficulty achieving optimal dietary intake, yet improved well-being is associated with following healthy dietary patterns. Individuals with food literacy-the inter-related knowledge, skills, and behaviors to plan and manage, select, prepare, and eat healthy foods-are better able to meet dietary recommendations. The Eating with Ease program developed and tested a nutrition education/culinary skill-building program to build first- and second-year veterinary medicine students' food literacy and healthy behaviors toward food. The curriculum emphasized health and nutrition, taste, food preparation skills, planning/decision making, and convenience. Students engaged in four 30-minute sessions and communicated through a mobile group messaging application. Pre- and post-program scores on the Eating and Food Literacy Behaviors Questionnaire (EFLBQ) were compared between those who finished the intervention and a control group of graduate students who completed a money management program. The intervention group (n = 23) had a mean age of 24.2 years (SD = 2.6), and the control group (n = 14) had a mean age of 27.1 years (SD = 2.3). Most participants were female (87%, n = 20 and 79%, n = 11 in the intervention and control groups, respectively). After completing the program, the veterinary medical students' mean EFLBQ factor change score for health and nutrition was significantly higher (p = .03) when compared to the control group. These findings suggest that a short, evidence-based nutrition education/culinary skill-building program may improve veterinary medical students' behaviors to choose, prepare and consume healthy foods.

The Use of Health Equity Impact Assessments to Modify Evidence Based Strategies within Local Health Departments in North Carolina.

BACKGROUND: Health equity impact assessments (HEIAs) inform the reduction of health inequities by evaluating programs or policies that affect target populations. Local health departments (LHD) receiving funding through the Improving Community Outcomes for Maternal and Child Health (ICO4MCH) Program conducted HEIAs for evidence-based strategies (EBSs). This paper describes the impact of HEIAs on the implementation of EBSs and highlights lessons learned during implementation of HEIA modifications. METHODS: We conducted a content analysis using data from the HEIA Modification Tracker and focus groups to identify themes and lessons learned. RESULTS: Fifteen HEIAs were conducted by five LHDs between 2016 and 2020. The most common modifications to EBS implementation were 1) increasing education and training for community members and 2) altering messaging mediums and language to reach intended audiences. DISCUSSION: Health equity impact assessments serve as a systematic and tangible way to center health equity, reflect on past processes, and inform improvements.

The Synucleins and the Astrocyte.

Synucleins consist of three proteins exclusively expressed in vertebrates. α-Synuclein (αS) has been identified as the main proteinaceous aggregate in Lewy bodies, a pathological hallmark of many neurodegenerative diseases. Less is understood about ß-synuclein (ßS) and γ-synuclein (γS), although it is known ßS can interact with αS in vivo to inhibit aggregation. Likewise, both γS and ßS can inhibit αS's propensity to aggregate in vitro. In the central nervous system, ßS and αS, and to a lesser extent γS, are highly expressed in the neural presynaptic terminal, although they are not strictly located there, and emerging data have shown a more complex expression profile. Synapse loss and astrocyte atrophy are early aspects of degenerative diseases of the brain and correlate with disease progression. Synucleins appear to be involved in synaptic transmission, and astrocytes coordinate and organize synaptic function, with excess αS degraded by astrocytes and microglia adjacent to the synapse. ßS and γS have also been observed in the astrocyte and may provide beneficial roles. The astrocytic responsibility for degradation of αS as well as emerging evidence on possible astrocytic functions of ßS and γS, warrant closer inspection on astrocyte-synuclein interactions at the synapse.

Identification of a Dau c PRPlike protein (Dau c 1.03) as a new allergenic isoform in carrots (cultivar Rodelika).

BACKGROUND: Up to 25% of food allergic subjects in central Europe suffer from carrot allergy. Until now, two isoforms of the major carrot (Daucus carota) allergen Dau c 1 have been described: Dau c 1.01, comprising five variants (Dau c 1.0101-Dau c 1.0105) and Dau c 1.02. OBJECTIVE: To investigate potential allergenic properties of a Dau c PRPlike protein, a novel isoform of the PR-10 protein family in carrot. METHODS: Dau c PRPlike cDNA from carrot roots (cv Rodelika) was cloned after RT-PCR and 5'RACE. Dau c PRPlike protein was expressed in E. coli, purified under native conditions by Ni-NTA chromatography and analysed by CD spectroscopy. Immuno-reactivity of the rDau c PRPlike protein was compared with rDau c 1.0104 and rDau c 1.0201 in terms of IgE binding (immunoblotting, ImmunoCAP), IgE cross-reactivity (ELISA inhibition) and in vitro mediator release with sera from carrot allergic patients. mRNA expression of Dau c PRPlike protein in wild-type and transgenic carrot roots was analysed by qRT-PCR. RESULTS: The Dau c PRPlike protein was identified as a new allergenic isoform, Dau c 1.03, in carrot roots. 68% of carrot allergic patients were sensitized to rDau c 1.03. The IgE-reactivity of rDau c 1.03 strongly correlated with reactivity to rDau c 1.0104, but not to rDau c 1.0201. The extent of IgE cross-reactivity and allergenic potency of Dau c 1 isoforms varied between the individual sera tested. Dau c 1.03 mRNA transcripts were up-regulated in Dau c 1.01 and Dau c 1.02 gene-silenced carrot roots. CONCLUSION AND CLINICAL RELEVANCE: Dau c 1 isoforms display distinct IgE epitope heterogeneity. Dau c 1.03 appears to contribute to the allergenicity of carrots and the manifestation of carrot allergy. The epitope diversity of different Dau c 1 isoforms should be considered for component-resolved diagnosis and gene silencing of carrot allergens.

Geospatial analysis of associations among mental health need, housing need, and involuntary psychiatric hospitalizations of people experiencing homelessness in Los Angeles County.

The purpose of this study was to use geospatial indicators of mental health need and homelessness in Los Angeles County Service Planning Areas (SPAs) and a psychiatric sample of adults who were homeless to investigate 1) overlap between SPA level of mental health need and corresponding volume of involuntary psychiatric hospitalizations over time; 2) overlap between SPA level of unsheltered homelessness and corresponding volume of involuntary psychiatric hospitalizations over time; and 3) associations between SPA level of mental health need, SPA level of unsheltered homelessness, and initiation of a mental health conservatorship for grave disability. A sample of 373 adults who were homeless and hospitalized on an involuntary psychiatric hold from 2016 to 2018 were linked to data from the Greater Los Angeles Homeless Count on unsheltered homelessness and from the California Health Interview Survey on need for mental health services and suicidality, using admission zip codes to link variables at the SPA level. Geospatial mapping and bivariate tests were used to examine geographic overlap of SPA mental health need and unsheltered homelessness with volume of involuntary psychiatric admissions over the study period. Multiple logistic regression modeling was used to examine associations of SPA mental health need and unsheltered homelessness with conservatorship initiation. The volume of patients admitted from SPAs with higher levels of mental illness need grew from 2016 to 2018 (Tau = 0.27, P < 0.001; Tau = 0.40, P < 0.001), but there were fewer patients admitted from SPAs with higher levels of unsheltered homelessness over the same years (Tau of -0.33, P < 0.001). Being admitted from SPAs with the highest levels of unsheltered homelessness was associated with higher odds of conservatorship initiation (OR = 1.73, 95% CI = 1.82-16.74). Results suggest a need for targeted mental health and housing services to reach areas of highest need in Los Angeles County.

Mental Health Conservatorship Among Homeless People With Serious Mental Illness.

OBJECTIVE: The purpose of this study was to examine associations between homelessness and length of psychiatric hospitalization and to explore the role of mental health conservatorship in determining discharge location for patients who are homeless and have a grave disability from serious mental illness. METHODS: This observational study used administrative data from a safety-net psychiatric hospital in Los Angeles. The sample included 795 adults (≥18 years) who were hospitalized on an involuntary psychiatric hold between 2016 and 2018. The outcome variables were length of stay (days) and discharge location (home, locked psychiatric facility, unlocked psychiatric facility, unhoused). The predictor variables were homelessness status and whether a mental health conservatorship was initiated during hospitalization. Multiple regression models were used to estimate associations between variables. RESULTS: Homelessness status was associated with 27.5 additional days (SE=3.5 days) of hospitalization in adjusted models. Homeless patients for whom conservatorship was initiated comprised 6% of the sample but 41% of total inpatient days. Among people who were homeless, initiation of a conservatorship was associated with significantly longer length of inpatient stay (mean=154.8 days versus 25.6 days for the whole sample) but also with lower odds of being unhoused at the time of discharge (risk ratio=0.19, 95% confidence interval=0.09-0.34). CONCLUSIONS: A mental health conservatorship can be a mechanism for helping homeless people with a grave disability from mental illness to transition from the streets to residential psychiatric treatment, but it requires substantial resources from facilities that initiate such conservatorships and does not guarantee resolution of long-term supportive housing needs.

Lion and spotted hyena distributions within a buffer area of the Serengeti-Mara ecosystem.

Most large carnivore populations are declining due to anthropogenic activities including direct persecution, prey depletion, habitat loss and degradation. protected areas (PAs) can help maintain viable large carnivore populations; however, anthropogenic activities occurring near and within PA borders or edges can reduce their effectiveness. We investigated the influence of edge effects on abundance of lions (Panthera leo) and spotted hyenas (Crocuta crocuta) in Maswa Game Reserve (MGR), a part of the Serengeti ecosystem in northern Tanzania. We conducted repeated call-ins to attract and enumerate lions and hyenas at 20 stations in MGR during June-July 2017. We used N-mixture models to estimate hyena and lion abundance in relation to land cover and distance from the south-western MGR borders which are adjacent to villages. We found lowest lion and hyena abundances by the south-western border, with abundance of both species increasing toward the eastern border adjacent to Serengeti National Park. Lions were uniformly distributed among land covers whereas hyenas were more abundant in woodlands. We suggest that reduced lion and hyena abundance near human settlements was in response to depleted prey, due to human actions. We recommend ecologically compatible land uses and effective border patrols to mitigate these adverse effects.

Enhanced antifungal and insect α-amylase inhibitory activities of Alpha-TvD1, a peptide variant of Tephrosia villosa defensin (TvD1) generated through in vitro mutagenesis.

TvD1 is a small, cationic, and highly stable defensin from the weedy legume, Tephrosia villosa with demonstrated in vitro antifungal activity. We show here peptide modifications in TvD1 that lead to enhanced antifungal activities. Three peptide variants, S32R, D37R, and Alpha-TvD1 (-G-M-T-R-T-) with variations in and around the ß2-ß3 loop region that imposes the two ß-strands, ß2 and ß3 were generated through in vitro mutagenesis. Alpha-TvD1 exhibited enhanced antifungal activity against the fungal pathogens, Fusarium culmorum and Fusarium oxysporum with respective IC(50) values of 2.5 µM and 3.0 µM, when compared to S32R (<5.0 µM and >5.0 µM), D37R (5.5 µM and 4.5 µM), and the wild type TvD1 (6.5 µM). Because of the enhanced antifungal activity, this variant peptide was characterized further. Growth of F. culmorum in the presence of Alpha-TvD1 showed deformities in hyphal walls and nuclear damage. With respect to the plant pathogenic bacterium, Pseudomonas syringae pv. tomato strain DC3000, both Alpha-TvD1 and the wild type TvD1 showed comparable antibacterial activity. Both wild type TvD1 and Alpha-TvD1 displayed inhibitory activity against the α-amylase of the mealworm beetle, Tenebrio molitor (TMA) with the latter showing enhanced activity. The human salivary as well as barley α-amylase activities were not inhibited even at concentrations of up to 50 µM, which has been predicted to be due to differences in the pocket size and the size of the interacting loops. Present study shows that the variant Alpha-TvD1 exhibits enhanced antifungal as well as insect α-amylase inhibitory activity.

Effects of genotype and AgNO3 on shoot regeneration in winter cultivars of rapeseed (Brassica napus).

Ability of shoot regeneration from cotyledon explants of rapeseed (Brassica napus) winter genotypes and the effect of silver nitrate and naphthalene acetic acid in shoot regeneration were investigated. The optimum medium for regeneration was the medium supplemented with 3 mg L(-1) 6-Benzylaminopurine and 0.15 mg L(-1) 1-naphthaleneacetic acid. The addition of 5 mg L(-1) silver nitrate significantly improved shoot regeneration. Shoot regeneration response was strongly different between genotypes with a range of variation from 79% in spring genotype PF and 7% in Okpi. The highest root production was recorded on medium containing indol-3-butyric acid. The rooted plants successfully transferred to soil and adapted to greenhouse conditions. No abnormally was observed and the regenerated plants were morphologically similar to the field grown parental plants.
