Abstract

Few studies have investigated parents experiences with racism in the neonatal intensive care unit (NICU). Our objective was to explore how parents perceive their interactions with NICU staff and if/how racism in the NICU was experienced. Parents of infants receiving care in an urban NICU completed fixed choice surveys regarding their experiences and demographics, with 6 open-ended questions to elaborate on their fixed-choice responses. Using a constant comparative method informed by Constructivist Grounded Theory, we identified 3 main themes from the comments provided by 97 respondents: Care and harm coexisting, racism often manifesting as neglectful care, and the power differential is most impactful during times of parent advocacy. Parents spoke positively regarding their experiences and also reported disparate treatment attributed to their racial/ethnic identity. Racism was experienced by inappropriate comments and apathy toward parent requests, occurring during intimate interactions between staff and parents. Descriptions of parental advocacy efforts highlighted the lack of power they held in relation to the NICU staff. We recommend strengthening the focus on equity and mitigating power imbalances in the NICU.

Abstract

Rationale: Acute lung injury (ALI) carries a high risk of mortality but has no established pharmacologic therapy. We previously found that experimental ALI occurs through natural killer (NK) cell NKG2D receptor activation and that the cognate human ligand, MICB, was associated with ALI after transplantation. Objectives: To investigate the association of a common missense variant, MICBG406A, with ALI. Methods: We assessed MICBG406A genotypes within two multicenter observational study cohorts at risk for ALI: primary graft dysfunction (N = 619) and acute respiratory distress syndrome (N = 1,376). Variant protein functional effects were determined in cultured and ex vivo human samples. Measurements and Main Results: Recipients of MICBG406A-homozygous allografts had an 11.1% absolute risk reduction (95% confidence interval [CI], 3.2-19.4%) for severe primary graft dysfunction after lung transplantation and reduced risk for allograft failure (hazard ratio, 0.36; 95% CI, 0.13-0.98). In participants with sepsis, we observed 39% reduced odds of moderately or severely impaired oxygenation among MICBG406A-homozygous individuals (95% CI, 0.43-0.86). BAL NK cells were less frequent and less mature in participants with MICBG406A. Expression of missense variant protein MICBD136N in cultured cells resulted in reduced surface MICB and reduced NKG2D ligation relative to wild-type MICB. Coculture of variant MICBD136N cells with NK cells resulted in less NKG2D activation and less susceptibility to NK cell killing relative to the wild-type cells. Conclusions: These data support a role for MICB signaling through the NKG2D receptor in mediating ALI, suggesting a novel therapeutic approach.

Abstract

Natural killer (NK) cells are innate lymphocytes capable of mediating immune responses without prior sensitization. NK cells express Fc-gamma receptors (FcγRs) that engage the Fc region of IgG. Studies investigating the role of FcγRs on mouse NK cells have been limited due to lack specific reagents. In this study, we characterize the expression and biological consequences of activating mouse NK cells through their FcγRs. We demonstrate that most NK cells express the activating CD16 receptor, and a subset of NK cells also expresses the inhibitory CD32b receptor. Critically, these FcγRs are functional on mouse NK cells and can modulate antibody-mediated responses. We also characterized mice with conditional knockout alleles of Fcgr3 (CD16) or Fcgr2b (CD32b) in the NK and innate lymphoid cell (ILC) lineage. NK cells in these mice did not reveal any developmental defects and were responsive to cross-linking activating NK receptors, cytokine stimulation, and killing of YAC-1 targets. Importantly, CD16-deficient NK cells failed to induce antibody-directed cellular cytotoxicity of antibody-coated B-cell lymphomas in in vitro assays. In addition, we demonstrate the important role of CD16 on NK cells using an in vivo model of cancer immunotherapy using anti-CD20 antibody treatment of B-cell lymphomas.

Abstract

Although interactions between inhibitory Ly49 receptors and their self-MHC class I ligands in C57BL/6 mice are known to limit NK cell proliferation during mouse CMV (MCMV) infection, we created a 36-marker mass cytometry (CyTOF) panel to investigate how these inhibitory receptors impact the NK cell response to MCMV in other phenotypically measurable ways. More than two thirds of licensed NK cells (i.e., those expressing Ly49C, Ly49I, or both) in uninfected mice had already differentiated into NK cells with phenotypes indicative of Ag encounter (KLRG1+Ly6C-) or memory-like status (KLRG1+Ly6C+). These pre-existing KLRG1+Ly6C+ NK cells resembled known Ag-specific memory NK cell populations in being less responsive to IL-18 and IFN-α stimulation in vitro and by selecting for NK cell clones with elevated expression of a Ly49 receptor. During MCMV infection, the significant differences between licensed and unlicensed (Ly49C-Ly49I-) NK cells disappeared within both CMV-specific (Ly49H+) and nonspecific (Ly49H-) responses. This lack of heterogeneity carried into the memory phase, with only a difference in CD16 expression manifesting between licensed and unlicensed MCMV-specific memory NK cell populations. Our results suggest that restricting proliferation is the predominant effect licensing has on the NK cell population during MCMV infection, but the inhibitory Ly49-MHC interactions that take place ahead of infection contribute to their limited expansion by shrinking the pool of licensed NK cells capable of robustly responding to new challenges.

Abstract

The cyanotoxin cylindrospermopsin (CYN) has been postulated to cause neurotoxicity, although the studies in this concern are very few. In addition, some studies in vitro indicate its possible effects on development. Furthermore, pesticides can be present in the same environmental samples as cyanotoxins. Therefore, chlor-pyrifos (CPF) has been one of the most common pesticides used worldwide. The aim of this report was to study the effects of CYN, isolated and in combination with CPF, in a developmental neurotoxicity in vitro model. The human neuroblastoma SH-SY5Y cell line was exposed during 6 days of differentiation to both toxics to study their effects on cell viability and neurite outgrowth. To further evaluate effects of both toxicants on cholinergic signaling, their agonistic and antagonistic activities on the alpha 7 homomeric nicotinic acetylcholine receptor (nAChR) were studied upon acute exposure. Moreover, a transcriptomic analysis by qPCR was performed after 6 days of CYN-exposure during differentiation. The results showed a concentration-dependent decrease on both cell viability and neurite outgrowth for both toxics isolated, leading to effective concentration 20 (EC20) values of 0.35 mu M and 0.097 mu M for CYN on cell viability and neurite outgrowth, respectively, and 100 mu M and 58 mu M for CPF, while the combination demonstrated no significant variations. In addition, 95 mu M and 285 mu M CPF demonstrated to act as an antagonist to nicotine on the nAChR, although CYN up to 2.4 mu M had no effect on the efficacy of these receptors. Additionally, the EC20 for CYN (0.097 mu M) on neurite outgrowth downregulated expression of the 5 genes NTNG2 (netrin G2), KCNJ11 (potassium channel), SLC18A3 (vesicular acetylcholine transporter), APOE (apolipoprotein E), and SEMA6B (semaphorin 6B), that are all important for neuronal development. Thus, this study points out the importance of studying the effects of CYN in terms of neurotoxicity and developmental neuroto

11. Dispelling Seven Myths Concerning Latina/o Students: A Call to Action for School Counselors

Author

Cavazos, Javier, Cavazos, Alyssa G., and Hinojosa, Maria G.

Abstract

Research has illustrated that school counselors "do not" provide Latina/o students with sufficient information about higher education (Immerwahr, 2003; Zalaquett, 2005), high expectations (Martinez, 2003), and individual counseling and guidance (Vela Gude et al., in press). Because school counselors are supposed to play an important role in helping Latina/o students pursue higher education (Villalba, Akos, Keeter, & Ames, 2007), the current article identifies seven myths concerning a growing Latina/o population: (1) parents do not value education, (2) students do not value education, (3) low expectations do not exist, (4) students are receiving sufficient guidance, (5) perceived ability level is the most important factor in eventual academic achievement, (6) personal barriers are more detrimental than systemic barriers, and (7) students do not have the ability to adopt a futuristic orientation. Hopefully, this article will encourage school counselors to help Latina/o students by providing quality attention and advisement, high expectations, and information about higher education.

Abstract

Since ancient times, breastfeeding has been the fundamental way of nurturing the newborn. The benefits of breast milk are widely known, as it is a source of essential nutrients and provides immunological protection, as well as developmental benefits, among others. However, when breastfeeding is not possible, infant formula is the most appropriate alternative. Its composition meets the nutritional requirements of the infant, and its quality is subject to strict control by the authorities. Nonetheless, the presence of different pollutants has been detected in both matrices. Thus, the aim of the present review is to make a comparison between the findings in both breast milk and infant formula in terms of contaminants in the last decade, in order to choose the most convenient option depending on the environmental conditions. For that, the emerging pollutants including metals, chemical compounds derived from heat treatment, pharmaceutical drugs, mycotoxins, pesticides, packaging materials, and other contaminants were described. While in breast milk the most concerning contaminants found were metals and pesticides, in infant formula pollutants such as metals, mycotoxins, and packaging materials were the most outstanding. In conclusion, the convenience of using a feeding diet based on breast milk or either infant formula depends on the maternal environmental circumstances. However, it is important to take into account the immunological benefits of the breast milk compared to the infant formula, and the possibility of using breast milk in combination with infant formula when the nutritional requirements are not fulfilled only with the intake of breast milk. Therefore, more attention should be paid in terms of analyzing these conditions in each case to be able to make a proper decision, as it will vary depending on the maternal and newborn environment.

Abstract

Methylmercury (MeHg) is a developmental neurotoxicant, and one potential mechanism of MeHg toxicity is epigenetic dysregulation. In a recent meta-analysis of epigenome-wide association studies (EWAS), associations between prenatal MeHg exposure and DNA methylation at several genomic sites were identified in blood from newborns and children. While EWASs reveal human-relevant associations, experimental studies are required to validate the relationship between exposure and DNA methylation changes, and to assess if such changes have implications for gene expression. Herein, we studied DNA methylation and gene expression of five of the top genes identified in the EWAS meta-analysis, MED31, MRPL19, GGH, GRK1, and LYSMD3, upon MeHg exposure in human SH-SY5Y cells exposed to 8 or 40 nM of MeHg during differentiation, using bisulfite-pyrosequencing and qPCR, respectively. The concentrations were selected to cover the range of MeHg concentrations in cord blood (2–8.5 μg/L) observed in the cohorts included in the EWAS. Exposure to MeHg increased DNA methylation at MED31, a transcriptional regulator essential for fetal development. The results were in concordance with the epidemiological findings where more MED31 methylation was associated with higher concentrations of MeHg. Additionally, we found a non-significant decrease in DNA methylation at GGH, which corresponds to the direction of change observed in the EWAS, and a significant correlation of GGH methylation with its expression. In conclusion, this study corroborates some of the EWAS findings and puts forward candidate genes involved in MeHg’s effects on the developing brain, thus highlighting the value of experimental validation of epidemiological association studies.

17. A Comparison of Open Enrollment Charter Schools and Traditional Public Schools in a Texas Region

Author

Hinojosa, Maria

Abstract

Open enrollment charter schools are monitored and accredited under the statewide testing and accountability system, just like traditional public schools. Accountability is critical for charter schools because if these schools do not improve student achievement they are at risk of having their charter terminated. As of the most recent publication by TEA (2009), Region 20 Educational Service Center area has 29 approved charters and 52 open enrollment sites. Since there is little research conducted on charter schools, this study determined if charter schools are in fact an effective alternative to traditional education. The study examined student achievement, attendance rates, dropout rates, and expenditures per pupil in both charter schools and traditional schools in Region 20. The data used for this study was collected using pre-existing data sets: TEA 2008 Snapshot; Texas Education Agency report entitles Texas Open-Enrollment Charter Schools Evaluation, February 2008; and the Academic Excellence Indicator System Data Files for 2007-2008. The sample for this study included 30 open enrollment charter high schools and 30 traditional high schools in Region 20 during the 2007-2008 school year. An examination of the findings indicated that exit level mathematics results for charter schools was ( M = 53.60, SD = 23.032), and for traditional schools was ( M = 77.13, SD = 12.275), indicating that traditional schools have a higher average in math exit level TAKS scores. Science TAKS scores for charter schools was ( M = 55.53, SD = 20.082), and for traditional schools was ( M = 79.93, SD = 12.275), indicating that traditional schools have a higher average in science exit level TAKS scores. Attendance rates results for charter schools was ( M = 90.63, SD = 5.5061), and for traditional schools was ( M = 95.363, SD = 0.8743), indicating that traditional schools have a higher average in attendance rates. Dropout rate results for charter schools was ( M = 8.603, SD = 11.5188), and for traditional schools was ( M = 3.198, SD = 2.6375), indicating that traditional schools have a lower dropout rate than charter schools. Expenditures per pupil for charter schools was ( M = $5,838.90, SD = 2957.77), and for traditional schools was ( M = $7,816.37, SD = 4080.12), indicating that traditional schools have higher expenditures per pupil than charter schools. In addition, a one way analysis of variance was conducted on all null hypotheses. The (ANOVA) found each dependent variable (school achievement, attendance rates, dropout rates, and expenditures per pupil) to be statistically significant to school type (charter vs. traditional). The study is significant in that it provided valuable data for the participating traditional school districts and charter schools in the Region 20 Educational Service center area. In addition, the study provided valuable information to higher educational institutions interested in alternative education models and whether or not they are effective tools in the accountability arena.

18. Impact of endocrine disrupting chemicals on neurodevelopment : the need for better testing strategies for endocrine disruption-induced developmental neurotoxicity

Abstract

Introduction: Brain development is highly dependent on hormonal regulation. Exposure to chemicals disrupting endocrine signaling has been associated with neurodevelopmental impairment. This raises concern about exposure to the suspected thousands of endocrine disruptors, and has resulted in efforts to improve regulation of these chemicals. Yet, the causal links between endocrine disruption and developmental neurotoxicity, which would be required for regulatory action, are still largely missing. Areas covered: In this review, we illustrate the importance of two endocrine systems, thyroid hormone and retinoic acid pathways, for neurodevelopment. We place special emphasis on TH and RA synthesis, metabolism, and how endocrine disrupting chemicals known or suspected to affect these systems are associated with developmental neurotoxicity. Expert opinion: While it is clear that neurodevelopment is dependent on proper hormonal functioning, and evidence is increasing for developmental neurotoxicity induced by endocrine disrupting chemicals, this is not grasped by current chemical testing. Thus, there is an urgent need to develop test methods detecting endocrine disruption in the context of neurodevelopment. Key to this development is further mechanistic insights on the involvement of endocrine signaling in neurodevelopment as well as increased support to develop and validate new test methods for the regulatory context.

Ministerio Pastoral, Justificados por la Fe
Abstract

En el primer trabajo exegético se hizo referencia al establecimiento de las iglesias en Galacia, y al deslizamiento de convicciones que los gálatas empezaron a tener propiciado por un grupo intruso, yendo así tras una doctrina errada en cuanto a la justificación y la santificación. También se explicó el contexto anterior a 2:11-16, lo cual no se repetirá en el presente trabajo. Luego del pasaje de la reprensión a Pedro en Antioquía por su desviación práctica al evangelio por la fe en Cristo sin las obras de la ley, Pablo afirma en 2:15-21 que los judíos son libres de la ley. Al ser justificados por la fe, los judíos debían reconocer que una vida de santidad, agradable a Dios, no se logra con un nuevo sometimiento a la ley de Moisés, sino confiando plenamente en el poder de Dios gracias a la obra de Cristo en la cruz. Pablo mismo había muerto para la ley, y por su identificación con Cristo en la muerte y resurrección, ahora vivía para Dios (2:20). Gálatas 2:21 es contundente, cuando Pablo dice que no desecha la gracia (la muerte gratuita de Jesucristo a favor nuestro), y continúa diciendo “porque si mediante la ley fuese la justicia, entonces Cristo por demás murió”. En los capítulos 3 y 4 Pablo argumenta de varias formas que el evangelio verdadero es de la fe en Cristo y no de las obras de la ley. Primero Pablo expone el argumento de la experiencia de los gálatas al convertirse (3:1-5). Ellos recibieron el Espíritu Santo no por el cumplimiento de las obras de la ley sino por la fe, es decir, por creer en la obra de Cristo. Además, si ellos experimentaron maravillas, no fue por las obras de la ley, sino por la fe. Seguidamente Pablo expone su argumento escritural basándose en Génesis 15:6. Explica que Abraham fue justificado no porque fue circuncidado –como seguramente enseñaban los judaizantes-, sino porque creyó a Dios en cuanto a la promesa. Según la promesa de Génesis 12:3, Pablo afirma que las naciones (incluyendo gentiles y judíos) son bendecidas con el creyente Abraham por medio de la fe -siguiendo el ejemplo del mismo Abraham- e incorporadas así en Abraham recibiendo las bendiciones prometidas a él. Sin dejar el apoyo de la Escritura, Pablo ahora –como dice Gary Williams- presenta el “lado negativo del argumento: la bendición no se recibe por las obras de la ley”.

Abstract

Indurated volcanic deposits occur worldwide. In Ecuador, they are known as “cangahua”, a Quechua word for “hard, sterile soil”. About 15% of the cultivated area in the Highland region of Ecuador is underlain by cangahua. Improper cultivation practices lead to erosion and expo-sure of the hard cangahua material. The properties and mode(s) of for-mation of cangahua are not well understood. This thesis aims at shed-ding new light on the origin and processes responsible for the formation of cangahua. Three outcrops located in the Central and Northern Highland were stud-ied. These are comprised of tephra deposits, cangahua layers and soil horizons. Chemical and mineralogical analyses revealed that the parent materials of the cangahua layers were sourced from the closest volcanic centers. Most cangahuas probably relate to individual explosive erup-tions although some may have formed on tephra from different volca-noes. Grainsize analyses suggested that the parent materials correspond either to pyroclastic fall or flow deposits. Both geological (syn-deposition) and pedological (post-deposition) pro-cesses contributed to induration of cangahua’s parent material. As a re-sult, the weathering status of cangahua can vary significantly. Thus, cangahua classification should consider the stage at which induration occurs: geogenetic (syn-deposition induration via geological processes), pedogenetic (post-deposition induration via pedological processes) and pedo-geogenetic (syn-deposition induration via geological processes reinforced by post-deposition induration via pedological processes). Mineralogical analyses revealed that pedo-geogenetic cangahua layers dated at 23 and 32 cal ky BP were exposed to alternating wet-dry climat-ic conditions after and just before/during the Last Glacial Maximum in Ecuador., (AGRO - Sciences agronomiques et ingénierie biologique) -- UCL, 2019
