The Witness of the Worshiping Community
(Excerpt)
Christ is risen! Alleluia! CR: He is risen indeed! Alleluia!) What more does the church have to do than to proclaim this? What else must the church witness to than the resurrection of the crucified One, who is present in its midst through the preaching of the gospel and the administration of the sacraments? Oh, yes, we have to spin out the meaning of the cross and resurrection of Christ; we have to celebrate it worthily and compellingly in our public assemblies; we have to reorder our lives In conformity with its implications, turning away from the way of the world and toward the new life under Christ\u27s reign; we have to invite others to reorder their lives according to this new reality for the world; and we want to invite them to join us in a community of proclamation and celebration
The Constitution on the Sacred Liturgy and Lutheran Book of Worship: What Was Renewed?
(Excerpt) Missing first four pages
of the 1970s there were those who objected to the idea of liturgy as action because they thought it placed an undue emphasis on human activity instead of on God\u27s work through the means of grace.4 Obviously, liturgy is a work performed by a person or a community, so human action is unavoidable. It is a human act to read scriptures, preach sermons, baptize, or proclaim the words of institution, even though we confess that the Holy Spirit works through these means of grace to create or awaken faith. One may also say that liturgy, like all the activities of the church, is inspired or engendered by the Holy Spirit. For this reason the chief service has been called \u27\u27the divine liturgy (e.g. the Divine Liturgy of St. John Chrysostom)
The Meaning of Advent: Implications for Preaching
If we confess that the Holy Spirit, at work in the church at all times and in all places, in some sense inspired the development of a liturgical calendar and a pericopal system for the expansion of the Mystery, the edification of the faithful, and the amplification of preaching possibilities, then we must also confess that the Spirit could effect changes in the meaning of the various feasts and liturgical seasons with the passage of time and with shifts in the expression of piety. The Holy Spirit did not retire in the fourth century any more than he did after the day of Pentecost
Martin Luther\u27s Revision of the Eucharistic Canon in the Formula Missae of 1523
Martin Luther was the most conservative of the Reformers when it came to the work of liturgical revision. This was nowhere more evident than in his first effort at revising the Mass for evangelical usage: the Formula missae et communionis of 1523. He retained the use of the Latin language along with the optional use of lights, incense, and vestments. On the whole, the Formula missae faithfully followed the traditional Western structure, sequence, and content of the Mass. It is characterized not by what Luther added to the traditional Mass, but by what he deleted
Detection of atomic spin labels in a lipid bi-layer using a single-spin nanodiamond probe
Magnetic field fluctuations arising from fundamental spins are ubiquitous in
nanoscale biology, and are a rich source of information about the processes
that generate them. However, the ability to detect the few spins involved
without averaging over large ensembles has remained elusive. Here we
demonstrate the detection of gadolinium spin labels in an artificial cell
membrane under ambient conditions using a single-spin nanodiamond sensor.
Changes in the spin relaxation time of the sensor located in the lipid bilayer
were optically detected and found to be sensitive to near-individual proximal
gadolinium atomic labels. The detection of such small numbers of spins in a
model biological setting, with projected detection times of one second, opens a
new pathway for in-situ nanoscale detection of dynamical processes in biology.Comment: 16 pages, 4 figure
Blood n-3 fatty acid levels and total and cause-specific mortality from 17 prospective studies.
The health effects of omega-3 fatty acids have been controversial. Here we report the results of a de novo pooled analysis conducted with data from 17 prospective cohort studies examining the associations between blood omega-3 fatty acid levels and risk for all-cause mortality. Over a median of 16 years of follow-up, 15,720 deaths occurred among 42,466 individuals. We found that, after multivariable adjustment for relevant risk factors, risk for death from all causes was significantly lower (by 15-18%, at least p < 0.003) in the highest vs the lowest quintile for circulating long chain (20-22 carbon) omega-3 fatty acids (eicosapentaenoic, docosapentaenoic, and docosahexaenoic acids). Similar relationships were seen for death from cardiovascular disease, cancer and other causes. No associations were seen with the 18-carbon omega-3, alpha-linolenic acid. These findings suggest that higher circulating levels of marine n-3 PUFA are associated with a lower risk of premature death.The EPIC Norfolk study (DOI 10.22025/2019.10.105.00004) has received funding from the Medical Research Council (MR/N003284/1 and MC-UU_12015/1) and Cancer Research UK (C864/A14136).

Our aim was to examine associations of in vivo levels of selected fatty acids (16:0, 16:1n7, 18:0, 18:1n9) in DNL with incidence of type 2 diabetes (T2D). Methods and findings: Seventeen cohorts from 12 countries (7 from Europe, 7 from the United States, 1 from Australia, 1 from Taiwan; baseline years = 1970–1973 to 2006–2010) conducted harmonized individual-level analyses of associations of DNL-related fatty acids with incident T2D. In total, we evaluated 65,225 participants (mean ages = 52.3–75.5 years; % women = 20.4%–62.3% in 12 cohorts recruiting both sexes) and 15,383 incident cases of T2D over the 9-year follow-up on average. Cohort-specific association of each of 16:0, 16:1n7, 18:0, and 18:1n9 with incident T2D was estimated, adjusted for demographic factors, socioeconomic characteristics, alcohol, smoking, physical activity, dyslipidemia, hypertension, menopausal status, and adiposity. Cohort-specific associations were meta-analyzed with an inverse-variance-weighted approach. Each of the 4 fatty acids positively related to incident T2D. Relative risks (RRs) per cohort-specific range between midpoints of the top and bottom quintiles of fatty acid concentrations were 1.53 (1.41–1.66; p < 0.001) for 16:0, 1.40 (1.33–1.48; p < 0.001) for 16:1n-7, 1.14 (1.05–1.22; p = 0.001) for 18:0, and 1.16 (1.07–1.25; p < 0.001) for 18:1n9. Heterogeneity was seen across cohorts (I2 = 51.1%–73.1% for each fatty acid) but not explained by lipid fractions and global geographical regions. Further adjusted for triglycerides (and 16:0 when appropriate) to evaluate associations independent of overall DNL, the associations remained significant for 16:0, 16:1n7, and 18:0 but were attenuated for 18:1n9 (RR = 1.03, 95% confidence interval (CI) = 0.94–1.13). These findings had limitations in potential reverse causation and residual confounding by imprecisely measured or unmeasured factors. Conclusions: Concentrations of fatty acids in the DNL were positively associated with T2D incidence. Our findings support further work to investigate a possible role of DNL and individual fatty acids in the development of T2D

Investigation of the Acetylation Mechanism by GCN5 Histone Acetyltransferase
The histone acetylation of post-translational modification can be highly dynamic and play a crucial role in regulating cellular proliferation, survival, differentiation and motility. Of the enzymes that mediate post-translation modifications, the GCN5 of the histone acetyltransferase (HAT) proteins family that add acetyl groups to target lysine residues within histones, has been most extensively studied. According to the mechanism studies of GCN5 related proteins, two key processes, deprotonation and acetylation, must be involved. However, as a fundamental issue, the structure of hGCN5/AcCoA/pH3 remains elusive. Although biological experiments have proved that GCN5 mediates the acetylation process through the sequential mechanism pathway, a dynamic view of the catalytic process and the molecular basis for hGCN5/AcCoA/pH3 are still not available and none of theoretical studies has been reported to other related enzymes in HAT family. To explore the molecular basis for the catalytic mechanism, computational approaches including molecular modeling, molecular dynamic (MD) simulation and quantum mechanics/molecular mechanics (QM/MM) simulation were carried out. The initial hGCN5/AcCoA/pH3 complex structure was modeled and a reasonable snapshot was extracted from the trajectory of a 20 ns MD simulation, with considering post-MD analysis and reported experimental results. Those residues playing crucial roles in binding affinity and acetylation reaction were comprehensively investigated. It demonstrated Glu80 acted as the general base for deprotonation of Lys171 from H3. Furthermore, the two-dimensional QM/MM potential energy surface was employed to study the sequential pathway acetylation mechanism. Energy barriers of addition-elimination reaction in acetylation obtained from QM/MM calculation indicated the point of the intermediate ternary complex. Our study may provide insights into the detailed mechanism for acetylation reaction of GCN5, and has important implications for the discovery of regulators against GCN5 enzymes and related HAT family enzymes
