Sites of Belonging, Sites of Empowerment: How Asian American Girls Construct "Home" in a Borderland World

This ethnographic study explores the ways in which nine first, 1.5, and second generation Asian American high school girls imagine, search for, and construct home-like sites. The study revealed that "home" for the girls was not only the place where the girls sleep, their families reside, or the country from where they came. Instead, "home," was multiple, literal, and imagined spaces, places, and communities where the girls felt a sense of belonging, empowerment, community, ownership, safety, and opportunity. In order to examine the behaviors, meaning, and perspectives of these girls, I conducted participant observations, interviews, and focus groups at an Asian American youth organization as well as in the girls' homes, schools, and neighborhoods. I also had online communication with the girls and collected supplementary materials and sources. The study revealed that the girls had creativity and improvisational skills to invent various "homes" as they linked the many worlds in which they lived. The girls carved out multiple "homes" --through imagining belonging globally while building belonging locally. They imagined an expansive understanding of "home" in the deterritorialized world. They idealized their countries of origin, acknowledged the United States as a possible "home," portrayed a third possible homeland where they had never lived, and fashioned a pan-Asian consciousness. The girls not only imagined "homes" outside of their immediate view but also co-constructed a home-like community in their everyday lives. They named it the Basement Group, after the place where they hang out in school. They developed a group identity which honored five characteristics: 1) expansion of who is family to include friends, 2) pride in diversity and inclusivity, 3) celebrations of cultural fusion, 4) value of "natural" girlhood beauty, and 5) shared interest in Asian popular culture. They constructed a borderland community in which they could collectively celebrate and nurture their in-between lives. This study illuminated the power and complexity of their lives in-between as well as expanded the terrains of agency that the girls possessed. The study also revealed intersectional differences among the girls. It provided lessons for youth organizations and schools to create spaces where immigrant youth can thrive

Localization of Heat Shock Protein 27 (Hsp27) in the Rat Gingiva and its Changes with Tooth Eruption

Heat shock protein 27 kDa (Hsp27) functions as a molecular chaperon to prevent apoptosis as well as to contribute to the regulation of cell proliferation and differentiation during development. In the present study, the localization of Hsp27 in the oral epithelium of rats and its expression change during formation of the gingiva with the tooth eruption were examined immunohistochemically to elucidate the roles of Hsp27 in the oral mucosa

Reassociation of annelid giant hemoglobin from the polychaete Perinereis aibuhitensis

Annelid extracellular hemoglobin (Hb) is a supramolecule with molecular mass of ～3,500kDa. The giant Hb consists of 12 subassemblies (globin dodecamers, D) and 18 homodimeric linkers (L) of non-globin chain. The globin dodecamer and linker were isolated from the polychaete Perinereis aibuhittensis Hb separately. Subsequently, these two components were mixed in the presence of 1M urea at a neutral pH to reform a whole molecule of Hb. At first L was refined by reverse phase chromatography in organic solvent. On the other hand, Perinereis Hb was incubated in 4M urea solution at 4°C for 5 min, and applied to two amphoteric ion-exchange resin column to remove L stick to the resin, and to isolate only D. The eluate was condensed and subjected to gel filtration. As a result, an ingredient of molecule mass ～210 kDa, that is D, was provided in high yield. When D and L were mixed in the molar ratio of approximately 1:1 in 50mM phosphate buffer (pH 7.2) in the presence of 1 M urea at room temperature, most of the proteins met to natural Hb size again within about 20 hours. Furthermore, similar experiments were performed in 50 mM Tris-HCl buffer (pH 7.2) containing 1 M urea in the presence of 1 mM CaCl2 or 1mM EDTA. It was observed that the reassociation was affected substantially by the presence of Ca2+. In conclusion, the homodimeric linkers have the key role to form the gigantic Hb

Can i have a second child? dilemmas of mothers of children with pervasive developmental disorder: a qualitative study

<p>Abstract</p> <p>Background</p> <p>Pervasive developmental disorder (PDD) has an uncertain etiology, no method of treatment, and results in communication deficiencies and other behavioral problems. As the reported recurrence risk is 5%-10% and there are no methods of either prevention or prenatal testing, mothers of PDD children may face unique challenges when contemplating second pregnancies. The purpose of this study was to explore the mothers' lived experiences of second child-related decision-making after the birth of a child with PDD.</p> <p>Methods</p> <p>The participants for this study were restricted to mothers living within the greater Tokyo metropolitan area who had given birth to a first child with PDD within the past 18 years. The ten participants were encouraged to describe their experiences of second-child related decision-making after the birth of a child with PDD on the basis of semi-structured interviews. Data analysis was performed by using Interpretive Phenomenological Analysis (IPA), which is concerned with understanding what the participant thinks or believes about the topic under discussion.</p> <p>Results</p> <p>We identified two superordinate themes. The first was balancing hopes and fears, in which hope was the potential joy to be gained by the birth of a new child without PDD and fears were characterized as uncertainty of PDD and perception of recurrence risk, burden on later-born children, and negative effects on a child with PDD.</p> <p>The second superordinate theme was assessing the manageability of the situation, which was affected by factors as diverse as severity of PDD, relationship between mother and father, and social support and acceptance for PDD. Our 10 participants suffered from extreme psychological conflict, and lack of social support and acceptance for PDD created numerous practical difficulties in having second children.</p> <p>Conclusions</p> <p>Our participants faced various difficulties when considering second pregnancies after the birth of children with PDD in the Japanese society. As lack of social support and acceptance for PDD also played a large role in second child-related decision-making, creating a social environment that more fully accepts those disabled and providing flexible support systems for families of children with PDD are crucial.</p

Exome-wide association study to identify rare variants influencing COVID-19 outcomes : Results from the Host Genetics Initiative

Previously, the COVID-19 Host Genetics Initiative genome-wide association study used common variants to identify multiple loci associated with COVID-19 outcomes. However, variants with the largest impact on COVID-19 outcomes are expected to be rare in the population. Hence, studying rare variants may provide additional insights into disease susceptibility and pathogenesis, thereby informing therapeutics development. Here, we combined whole-exome and whole-genome sequencing from 21 cohorts across 12 countries and performed rare variant exome-wide burden analyses for COVID-19 outcomes. In an analysis of 5,085 severe disease cases and 571,737 controls, we observed that carrying a rare deleterious variant in the SARS-CoV-2 sensor toll-like receptor TLR7 (on chromosome X) was associated with a 5.3-fold increase in severe disease (95% CI: 2.75–10.05, p = 5.41x10-7). This association was consistent across sexes. These results further support TLR7 as a genetic determinant of severe disease and suggest that larger studies on rare variants influencing COVID-19 outcomes could provide additional insights.Peer reviewe

Identification of Disease-Promoting HLA Class I and Protective Class II Modifiers in Japanese Patients with Familial Mediterranean Fever

Objectives: The genotype-phenotype correlation of MEFV remains unclear for the familial Mediterranean fever (FMF) patients, especially without canonical MEFV mutations in exon 10. The risk of FMF appeared to be under the influence of other factors in this case. The contribution of HLA polymorphisms to the risk of FMF was examined as strong candidates of modifier genes. Methods: Genotypes of HLA-B and -DRB1 loci were determined for 258 mutually unrelated Japanese FMF patients, who satisfied modified Tel-Hashomer criteria, and 299 healthy controls. The effects of carrier status were evaluated for the risk of FMF by odds ratio (OR). The HLA effects were also assessed for clinical forms of FMF, subsets of FMF with certain MEFV genotypes and responsiveness to colchicine treatment. Results: The carriers of B?39:01 were increased in the patients (OR = 3.25, p = 0.0012), whereas those of DRB1?15:02 were decreased (OR = 0.45, p = 0.00050), satisfying Bonferroni\u27s correction for multiple statistical tests (n = 28, p<0.00179). The protective effect of DRB1?15:02 was completely disappeared in the co-existence of B?40:01. The HLA effects were generally augmented in the patients without a canonical MEFV variant allele M694I, in accordance with the notion that the lower penetrance of the mutations is owing to the larger contribution of modifier genes in the pathogenesis, with a few exceptions. Further, 42.9% of 14 colchicine-resistant patients and 13.5% of 156 colchicine-responders possessed B?35:01 allele, giving OR of 4.82 (p = 0.0041). Conclusions: The differential effects of HLA class I and class II polymorphisms were identified for Japanese FMF even in those with high-penetrance MEFV mutations
