TL;DR: In this article, the authors present a compilation of trace element data from approximately sixty published works for NIST SRM 611 and NISTSRM 613 and provide useful new working values for these reference materials.
Abstract: Microanalytical trace element techniques (such as ion probe or laser ablation ICP-MS) are hampered by a lack of well characterized, homogeneous standards. Two silicate glass reference materials produced by National Institute of Standards and Technology (NIST), NIST SRM 610 and NIST SRM 612, have been shown to be homogeneous and are spiked with up to sixty one trace elements at nominal concentrations of 500 μg g-1 and 50 μg g-1 respectively. These samples (supplied as 3 mm wafers) are equivalent to NIST SRM 611 and NIST SRM 613 respectively (which are supplied as 1 mm wafers) and are becoming more widely used as potential microanalytical reference materials. NIST however, only certifies up to eight elements in these glasses. Here we have compiled concentration data from approximately sixty published works for both glasses, and have produced new analyses from our laboratories. Compilations are presented for the matrix composition of these glasses and for fifty eight trace elements. The trace element data includes all available new and published data, and summaries present the overall average and standard deviation, the range, median, geometric mean and a preferred average (which excludes all data outside ± one standard deviation of the overall average). For the elements which have been certified, there is a good agreement between the compiled averages and the NIST data. This compilation is designed to provide useful new working values for these reference materials.

TL;DR: The results indicate that any degree of albuminuria is a risk factor for CV events in individuals with or without DM; the risk increases with the ACR, starting well below the microalbuminuria cutoff.
Abstract: ContextMicroalbuminuria is a risk factor for cardiovascular (CV) events. The
relationship between the degree of albuminuria and CV risk is unclear.ObjectivesTo estimate the risk of CV events in high-risk individuals with diabetes
mellitus (DM) and without DM who have microalbuminuria and to determine whether
levels of albuminuria below the microalbuminuria threshold increase CV risk.DesignThe Heart Outcomes Prevention Evaluation study, a cohort study conducted
between 1994 and 1999 with a median 4.5 years of follow-up.SettingCommunity and academic practices in North and South America and Europe.ParticipantsIndividuals aged 55 years or more with a history of CV disease (n =
5545) or DM and at least 1 CV risk factor (n = 3498) and a baseline urine
albumin/creatinine ratio (ACR) measurement.Main Outcome MeasuresCardiovascular events (myocardial infarction, stroke, or CV death);
all-cause death; and hospitalization for congestive heart failure.ResultsMicroalbuminuria was detected in 1140 (32.6%) of those with DM and 823
(14.8%) of those without DM at baseline. Microalbuminuria increased the adjusted
relative risk (RR) of major CV events (RR, 1.83; 95% confidence interval [CI],
1.64-2.05), all-cause death (RR, 2.09; 95% CI, 1.84-2.38), and hospitalization
for congestive heart failure (RR, 3.23; 95% CI, 2.54-4.10). Similar RRs were
seen for participants with or without DM, even after adjusting for other CV
risk factors (eg, the adjusted RR of the primary aggregate end point was 1.97
[95% CI, 1.68-2.31] in those with DM and 1.61 [95% CI, 1.36-1.90] in those
without DM).Compared with the lowest quartile of ACR (<0.22 mg/mmol), the
RRs of the primary aggregate end point in the second quartile (ie, ACR range,
0.22-0.57 mg/mmol) was 1.11 (95% CI, 0.95-1.30); third quartile, 1.38 (95%
CI, 1.19-1.60; ACR range, 0.58-1.62 mg/mmol); and fourth quartile, 1.97 (95%
CI, 1.73-2.25; ACR range, >1.62 mg/mmol) (P for trend
<.001, even after excluding those with microalbuminuria). For every 0.4-mg/mmol
increase in ACR level, the adjusted hazard of major CV events increased by
5.9% (95% CI, 4.9%-7.0%).ConclusionsOur results indicate that any degree of albuminuria is a risk factor
for CV events in individuals with or without DM; the risk increases with the
ACR, starting well below the microalbuminuria cutoff. Screening for albuminuria
identifies people at high risk for CV events.

TL;DR: Using exome sequencing, it is shown that analysis of rare coding variation in 3,871 autism cases and 9,937 ancestry-matched or parental controls implicates 22 autosomal genes at a false discovery rate of < 0.05, plus a set of 107 genes strongly enriched for those likely to affect risk (FDR < 0.30).
Abstract: The genetic architecture of autism spectrum disorder involves the interplay of common and rare variants and their impact on hundreds of genes. Using exome sequencing, here we show that analysis of rare coding variation in 3,871 autism cases and 9,937 ancestry-matched or parental controls implicates 22 autosomal genes at a false discovery rate (FDR) < 0.05, plus a set of 107 autosomal genes strongly enriched for those likely to affect risk (FDR < 0.30). These 107 genes, which show unusual evolutionary constraint against mutations, incur de novo loss-of-function mutations in over 5% of autistic subjects. Many of the genes implicated encode proteins for synaptic formation, transcriptional regulation and chromatin-remodelling pathways. These include voltage-gated ion channels regulating the propagation of action potentials, pacemaking and excitability-transcription coupling, as well as histone-modifying enzymes and chromatin remodellers-most prominently those that mediate post-translational lysine methylation/demethylation modifications of histones.

TL;DR: In this article, the authors explore membership roles by illustrating the insider status of one author and the outsider status of the other when conducting research with specific parent groups, and explore the strengths and challenges of conducting qualitative research from each membership status.
Abstract: Should qualitative researchers be members of the population they are studying, or should they not? Although this issue has been explored within the context of qualitative research, it has generally been reserved for discussions of observation, field research, and ethnography. The authors expand that discussion and explore membership roles by illustrating the insider status of one author and the outsider status of the other when conducting research with specific parent groups. The strengths and challenges of conducting qualitative research from each membership status are examined. Rather than consider this issue from a dichotomous perspective, the authors explore the notion of the space between that allows researchers to occupy the position of both insider and outsider rather than insider or outsider.
