Moving Beyond Google Translate: What Massachusetts Families from Diverse Cultures Need for Effective Autism Services and Supports
The project team conducted a state needs assessment of children and youth with Autism Spectrum Disorder (ASD) and Developmental Disabilities (DD) that aligns with the six MCHB Healthy People 2020 core indicators (i.e., early identification, medical home, access to community-based systems of care, family involvement, transition to adulthood, and insurance). The results will inform state efforts to establish a state-level data collection and surveillance plan for systems of services for children and youth with ASD and DD.
Preliminary data from the needs assessment across multiple sources indicate that screening and evaluation for ASD and other DD’s in Massachusetts occur less frequently in non-native English-speaking populations and other minority cultures, demonstrating a need for systemic improvement
Isoperimetric 3- and 4-Bubble Results on R With Density |x|
We study the isoperimetric problem on ℝ1 with a prescribed density function f(x)=|x|. Under these conditions, we find that isoperimetric 3-bubble and 4-bubble results satisfy a regular structure. As our regions increase in size, the intervals that form them alternate back-and-forth across the origin, with the smaller regions closer to the origin. This expands on previously known observations about the single- and double-bubble results on ℝ with density |x|p
Molecular characterisation of a bovine-like rotavirus detected from a giraffe
Background
Rotavirus (RV), is a member of the Reoviridae family and an important etiological agent of acute viral gastroenteritis in the young. Rotaviruses have a wide host range infecting a broad range of animal species, however little is known about rotavirus infection in exotic animals. In this paper we report the first characterisation of a RV strain from a giraffe calf. Results
This report describes the identification and detailed molecular characterisation of a rotavirus strain detected from a 14-day-old Giraffe (Giraffa camelopardalis), presenting with acute diarrhea. The RV strain detected from the giraffe was characterized molecularly as G10P[11]. Detailed sequence analysis of VP4 and VP7 revealed significant identity at the amino acid sequence level to Bovine RV (BoRV). Conclusion
This study demonstrates the need for continuous surveillance of RV strains in various animal populations, which will facilitate the identification of rotavirus hosts not previously reported. Furthermore, extending typical epidemiology studies to a broader host range will contribute to the timely identification of new emerging strain types
Characterization of density fluctuations during the search for an I-mode regime on the DIII-D tokamak
The I-mode regime, routinely observed on the Alcator C-Mod tokamak, is characterized by an edge energy transport barrier without an accompanying particle barrier and with broadband instabilities, known as weakly coherent modes (WCM), believed to regulate particle transport at the edge. Recent experiments on the DIII-D tokamak exhibit I-mode characteristics in various physical quantities. These DIII-D plasmas evolve over long periods, lasting several energy confinement times, during which the edge electron temperature slowly evolves towards an H-mode-like profile, while maintaining a typical L-mode edge density profile. During these periods, referred to as I-mode phases, the radial electric field at the edge also gradually reaches values typically observed in H-mode. Density fluctuations measured with the phase contrast imaging diagnostic during I-mode phases exhibit three features typically observed in H-mode on DIII-D, although they develop progressively with time and without a sharp transition: the intensity of the fluctuations is reduced; the frequency spectrum is broadened and becomes non-monotonic; two dimensional space-time spectra appear to approach those in H-mode, showing phase velocities of density fluctuations at the edge increasing to about 10 km s−1. However, in DIII-D there is no clear evidence of the WCM. Preliminary linear gyro-kinetic simulations are performed in the pedestal region with the GS2 code and its recently upgraded model collision operator that conserves particles, energy and momentum. The increased bootstrap current and flow shear generated by the temperature pedestal are shown to decrease growth rates, thus possibly generating a feedback mechanism that progressively stabilizes fluctuations.United States.

The Influence of Sample Volume Applied to the Makler Sperm Counting Chamber Upon the Measured Concentration of Latex Beads: A Multi-Centre Study
Objective: To undertake a multi-centre study to maximize the number of Makler chambers used.
Methods: A total of 15 laboratories participated with 31 Makler chambers. A suspension of latex beads was prepared to a concentration of 20 millions per milliliter, and 0.5 mL aliquots distributed to each participating laboratory. They measured the concentration on their Makler chamber(s) used for routine semen analysis by adding 3, 4, 5, 7 and 10 μL volumes of bead suspension to the chamber.
Results: There was no difference in within-chamber analysis of the bead concentration according to the volume of bead suspension applied within the range of 3–10 μL (F4,14=2.634, P=0.056). However, the between-chamber effects were significantly different (F30,124=4.937, P=0.000), and 24/31 (77.5%) chambers tested had an average bias\u3e10% compared to the target bead concentration.
Conclusions: A volume of 3–10 μL added to Makler counting chambers does not influence the concentration measured of latex beads, but the between-chamber variability and positive bias seen would suggest that other sources of error are present which are yet to be identified
Short RNAs Are Transcribed from Repressed Polycomb Target Genes and Interact with Polycomb Repressive Complex-2
Polycomb proteins maintain cell identity by repressing the expression of developmental regulators specific for other cell types. Polycomb repressive complex-2 (PRC2) catalyzes trimethylation of histone H3 lysine-27 (H3K27me3). Although repressed, PRC2 targets are generally associated with the transcriptional initiation marker H3K4me3, but the significance of this remains unclear. Here, we identify a class of short RNAs, ~50–200 nucleotides in length, transcribed from the 5′ end of polycomb target genes in primary T cells and embryonic stem cells. Short RNA transcription is associated with RNA polymerase II and H3K4me3, occurs in the absence of mRNA transcription, and is independent of polycomb activity. Short RNAs form stem-loop structures resembling PRC2 binding sites in Xist, interact with PRC2 through SUZ12, cause gene repression in cis, and are depleted from polycomb target genes activated during cell differentiation. We propose that short RNAs play a role in the association of PRC2 with its target genes.National Institutes of Health (U.S.) (Grant HG002668)National Institutes of Health (U.S.) (Grant NS055923

Pannexin 1 drives efficient epithelial repair after tissue injury
Epithelial tissues such as lung and skin are exposed to the environment and therefore particularly vulnerable to damage during injury or infection. Rapid repair is therefore essential to restore function and organ homeostasis. Dysregulated epithelial tissue repair occurs in several human disease states, yet how individual cell types communicate and interact to coordinate tissue regeneration is incompletely understood. Here, we show that pannexin 1 (Panx1), a cell membrane channel activated by caspases in dying cells, drives efficient epithelial regeneration after tissue injury by regulating injury-induced epithelial proliferation. Lung airway epithelial injury promotes the Panx1-dependent release of factors including ATP, from dying epithelial cells, which regulates macrophage phenotype after injury. This process, in turn, induces a reparative response in tissue macrophages that includes the induction of the soluble mitogen amphiregulin, which promotes injury-induced epithelial proliferation. Analysis of regenerating lung epithelium identified Panx1-dependent induction of Nras and Bcas2, both of which positively promoted epithelial proliferation and tissue regeneration in vivo. We also established that this role of Panx1 in boosting epithelial repair after injury is conserved between mouse lung and zebrafish tailfin. These data identify a Panx1-mediated communication circuit between epithelial cells and macrophages as a key step in promoting epithelial regeneration after injury
Assistants, Guides, Collaborators, Friends: The Concealed Figures of Conflict Research
Recent scholarship has demonstrated an increasing awareness of the need for more grounded, empirical research into the micro-level dynamics of violent contexts. Research in these difficult, dangerous, and potentially violent conflict or post-conflict settings necessitates the formation of new relationships of dependency, and assistants, friends, collaborators, and guides become central figures in the field. However, all too often, these figures are written out of academic accounts and silenced in our analyses. This not only does them a significant disservice, but it also obscures potential biases, complexities, and ethical dilemmas that emerge in the way in which such research is carried out. Drawing upon fieldwork exploring the 2007–2008 Kenyan postelection violence, this paper argues that reliance upon insider-assistants is essential in conflict settings and explores the challenges inherent in these relationships. As researchers become increasingly engaged in micro-level studies of violent contexts, we must interrogate the realities of how our knowledge has been produced and engage in more open and honest discussions of the methodological and ethical challenges of conflict research
