Background: Peach is among the main foods causing allergic reactions in the Mediterranean adult population. Only a single peach allergen, named Pru p 3, has been characterized. However, a potential ...role of profilin has also been suggested in grass pollen‐associated allergy to peach.
Methods: Complementary DNA clones for two different peach profilin isoforms were obtained by reverse transcriptase polymerase chain reaction using non‐degenerated primers. Expression of recombinant peach profilin was performed in Escherichia coli, and confirmed using rabbit polyclonal antibodies to sunflower pollen profilin. Twenty‐nine individual sera from patients with peach allergy proved by double‐blind, placebo‐controlled food challenges (DBPCFC), either with (n = 15) or without (n = 14) specific IgE to Bet v 2, were used in immunodetection assays to test recombinant peach profilin reactivity.
Results: Each peach profilin cDNA included an open reading frame coding for a 131 amino acid protein. The peach profilin isoforms, designated Pru p 4.01 and Pru p 4.02, showed 80% of amino acid sequence identity, and were very similar (>70% identity) to allergenic profilins from plant foods and pollens. Recombinant Pru p 4.01 was expressed in E. coli as a nonfusion protein, displaying the expected molecular size and reacting with anti‐profilin antibodies. rPru p 4.01 was recognized by all sera (15 of 15) with specific IgE to Bet v 2, whereas no sera (zero of 14) without IgE to this birch allergen reacted with rPru p 4.01.
Conclusions: Peach profilin Pru p 4 is very closed to other allergenic profilins from plant foods and pollens. A complete correlation between reactivity to rPru p 4 and rBet v 2 has been found in sera from peach allergic patients.
Objective. Currently, Latinos and African Americans constitute more than one-quarter of the U.S. population. The sheer size of these groups suggests an opportunity for increased political influence, ...with this opportunity providing the incentive for greater social and political interaction between them. The objective of this article is to determine the role of Latino group consciousness in the formation of attitudes toward African Americans. Methods. Utilizing data from the 1999 Washington Post/Henry J. Kaiser Family Foundation National Survey on Latinos, a multivariate ordered logit model is employed to test the relationship between Latino group consciousness and perceptions of commonality with African Americans. Results. Results show that group consciousness in the form of Latino internal commonality and perceived discrimination are contributors to Latino perceptions of commonality with African Americans. Conclusion. This analysis demonstrates that before any meaningful political alliances can be formed between the nation's two largest minority groups, Latinos may need to develop strong levels of panethnic identity.
This manuscript examines how personally knowing a deportee and/or undocumented immigrant affects the mental health of Latina/o adults. Utilising a new survey sponsored by the Robert Wood Johnson ...Foundation Center for Health Policy at the University of New Mexico (n = 1493), we estimate a series of logistic regressions to understand how personal connections to immigrants are affecting the mental health of Latinos using stress process theory. Our modelling approach takes into consideration the sociopolitical, familial, cultural, and personal contexts that make up the Latina/o experience, which is widely overlooked in datasets that treat Latinos as a homogeneous ethnic group. Our findings suggest that knowing a deportee increases the odds of having to seek help for mental health problems. The significance of this work has tremendous implications for policy makers, health service providers, and researchers interested in reducing health disparities among minority populations especially under a new administration, which has adopted more punitive immigration policies and enforcement.
Latino, Black, American Indian/Alaska Native (AI/AN), and Native Hawaiian or Other Pacific Islander people have the highest hospitalizations and death rates from COVID-19. Social inequalities have ...exacerbated COVID-19 related health disparities. This study examines social and structural determinants of COVID-19 vaccine uptake. Results from logistic regressions suggest Latino and Black people were less likely to be vaccinated. People that did not have health insurance, a primary care doctor and were unemployed were more than 30% less likely to be vaccinated for COVID-19. Greater perceived health inequalities in one’s neighborhood and perceived racial/ethnic discrimination were associated with a decreased odds in being vaccinated. People that suffered the loss of a household member from COVID-19 were three times more likely to have been vaccinated. Establishing policies that will increase access to health insurance and create jobs with living wages may have lasting impacts. Furthermore, collaboration with local and national community organizations can enhance the development of sustainable solutions.
Abstract
We explore the racial and ethnic politics associated with mask wearing early in the COVID-19 pandemic. Using panel and cross-sectional data from the National Panel Study of COVID-19 (n = ...1,996) fielded in March and April 2020, we asked Americans about their self-reported race/ethnicity, their political party affiliation, and if they have worn a mask or scarf in public to stop the spread of the coronavirus. We also asked respondents who reported wearing a mask in public if they worry they might be mistaken for a criminal. Our logistic regression models found that racial and ethnic minorities are more likely to wear a mask or scarf over their faces to prevent the spread of COVID-19 despite being more likely to worry about being criminalized by police or security while wearing a mask. We argue that proximal contact with the virus, because racial and ethnic minorities are more likely to be affected by COVID-19, leads to increased willingness by people in these groups to protect themselves and others. Democrats were also more likely to wear masks compared with Republican respondents. and those living in Republican-led states were less likely to wear a mask in public and more likely to be criminalized for wearing a mask.
Was mask use during the early COVID-19 pandemic political? In our paper, we use panel and cross-sectional data from the National Panel Study of COVID-19 fielded in March and April 2020 when we asked Americans whether they had worn masks. We also asked those who wore a mask if they felt criminalized while wearing a mask. Our findings show that there are stark differences in mask use between demographic groups and worrying about being criminalized while wearing one.
Purpose This research uses a translation experiment to assess the Spanish translation of the "fair" response in the self-rated health measure among a representative study of the Latino population in ...the USA. Methods Using a unique Latino-specific survey (n = 1200), researchers built in a split sample approach in the self-rated health status measure where half of the Spanish-speaking respondents (n = 600) were randomly given "regular" and the other half were given "Mas o Menos" in translating the English "fair" response. We first estimate a logistic regression model to estimate differences across language categories on the probability of reporting poor and fair health and then estimate a multinomial logistic regression to test whether respondents who took the survey in Spanish and given "regular" are more likely to rate their health as fair compared to English speakers and Spanish-speaking respondents who are given the "Mas o Menos" version. Results From our logistic regression model, we find that Spanish-speaking respondents given the "regular" response are more likely to report poor health relative to English-speaking respondents and Spanish-speaking respondents who were randomly given "Mas o Menos." The results from our multinomial logistic models suggest that Spanish respondents provided with "Mas o Menos" are more likely to rate their health as good relative to the base category of fair and relative to both English and Spanish speakers given "regular." Conclusion This research informs the study of racial and ethnic disparities by providing a detailed explanation for mixed findings in the Latino health disparities literature. Researchers interested in self-rated health should translate the general self-rated health option "fair" to "Mas o Menos" as our wording experiment suggests that the current wording "regular" overinflates the reporting of poor health.
There are significant geographic gaps in our knowledge of marine mammal evolution because most fossils have been found and described from Northern Hemisphere localities and a few other high-latitude ...areas in the Southern Hemisphere. Here, we describe fossil cetacean remains from five geological units in the South American tropics (Urumaco, Codore, Castilletes, Cantaure, and Querales formations) generally representing marginal marine depositional environments (estuaries, deltas, and tidal flats). While fossil cetaceans from Venezuelan Neogene localities have been previously studied, this paper includes the first descriptions of fossil cetaceans from Colombia, including a diverse assemblage of mysticetes and odontocetes. We identified and provisionally referred fragmentary remains to the iniid
Ischyrorhynchus vanbenedeni
and to the platanistid
Zarhachis flagellator
. The latter suggests the presence of Platanistidae in the eastern coast of South America during the early-middle Miocene, representing the second record of Platanistidae in South America and the first record of Platanistidae in eastern South America. Other less-diagnostic specimens are characterized by features commonly seen in longirostrine odontocetes such as Iniidae, Platanistidae, Pontoporiidae, Lipotidae, Eoplatanistidae, and Squalodelphinidae.
What did Native American women and men voters think about Donald Trump on the eve of the 2018 election? This question has important implications for understanding the gendered political attitudes of ...peoples adversely targeted by Trump’s politics. To examine this issue, we analyze a path-breaking, nationally representative sample of six hundred Native American voters. We find that Native Americans’ attitudes about sexual harassment are central to their attitudes about politics and policy in the Trump era. This relationship suggests that Native American voters are an informed electorate influenced by the president’s words and actions. Our work demonstrates multiple ways that gender influenced Native American politics during an election where gender and racial identities were central. In so doing, our work illuminates how race, institutions, and vulnerability affect the political attitudes of Native American voters, one of the least studied groups in American politics.
