The Fas TMD was reconstituted in q = 0.7 bicelles and DHPC was progressively added to reduce the bicelle size. The detergent was taken from a concentrated stock solution (660 mM DHPC) made in the same buffer of the protein sample and it was added in small aliquots (few μL per step) to minimize possible dilution effects. To monitor the progress of the titration by NMR, a 2D 1H-15N TROSY-HSQC spectrum was recorded at 600 MHz (Table S1) at each of the following q values: 0.7, 0.6, 0.5, 0.4 and 0.3. The chemical shift assignments of the human Fas TMD was taken from the Biological Magnetic Resonance Bank (BMRB)[20 (link)], entry 25930[1c (link)].

Table 2 lists simulations of pure DHPC and pure DPPC bilayers presented in this study. Structural and mechanical properties calculated include form factors ( |F(q)| ), SDP, Al , and KA . Properties focusing on the interaction of water with the ether and ester linkages are: pair-correlation functions, g(r) , of the ether oxygen (in DHPC) and ester and carbonyl oxygens (in DPPC) with water; and z-profiles of the electrostatic potential ( ψ ), water potential of mean force ( pmfw ), and density-weighted orientation of water dipole, ρ(z)cosθ(z) .
Bilayer simulations contained a total of 80 lipids (40 per leaflet) and 30 waters per lipid. Initial coordinates were produced by the CHARMM-GUI28 (link)Membrane Builder29 (link)–31 (link) for DPPC. Necessary atom-type substitutions and deletions were made to produce the ether linkage of DHPC. “C36” denotes partial-charge assignments based on C36 charges for PEG and unchanged dihedral parameters (see Sec. S2 and Table S1). “C36e” denotes the new partial-charge and dihedral parameters found in Sec. 3.1. Simulations were run in NAMD using a 2-fs timestep and Langevin damping coefficient of 1/ps. Data were analyzed after equilibration, from 30 – 100 ns. Standard errors between replicates were calculated for Al and scattering parameters, and from uncorrelated blocks for KA . “NBFIX” parameters for carboxylate, ester, and phosphate oxygens32 were used in simulations with NaCl.
The scattering densities of functional groups from simulation were obtained with the software package SIMtoEXP.33 (link) For ready comparison with the experimental SDP,12 (link) three Gaussians were used to describe the volume probabilities of the lipid headgroup: one each for the glycerol and ether linkage (G1), the phosphate and CH2CH2N moiety (G2), and the trimethyl groups of the terminal choline (G3). For calculating the bilayer hydrocarbon thickness (2DC), the total hydrocarbon region was represented by an error function. Matlab R2016a34 was used to fit the Gaussian and error functions and obtain the difference between electron density maxima (DHH). X-ray and neutron form factors were calculated using SIMtoEXP33 (link) with a Fourier transform of the total densities.
Area compressibility moduli of DHPC and DPPC bilayers were calculated using fluctuations in area:35 KA=kBTAlσAl2nL.
Here, σAl2 is the mean square fluctuation in area per lipid, nL is the number of lipids per leaflet, and kB is Boltzmann’s constant.
The electrostatic potential profile along the bilayer normal was calculated by integration of the Poisson equation:
ψ(z)=4πϵ00zρc(z)dz
where ρc is the total time-averaged charge density and ϵ0 is the permittivity of free space. ψ is greater at the center of the membrane than in bulk water. The total dipole potential drop across the membrane, ΔΨ , is here defined as the difference in the electrostatic potential of bulk water, ψ(0) , from that inside the membrane:36 ΔΨ=ψ(z)ψ(0)=4πϵ000z'ρc(z'')dz''dz'
CHARMM20 (link) was used to find the water density and dipole orientation with respect to position along the bilayer normal, ρ(z)cosθ(z) The software package Visual Molecular Dynamics (VMD)37 (link) was used to find the pair-correlation functions, g(r) , for ether oxygens of DHPC and carbonyl and ester oxygens of DPPC with water hydrogens, and to capture images of the bilayers. Peak positions and integrals of g(r) were computed with Matlab R2016a.34

For the first study aim, the outcomes were the regulators’ opinions regarding the need to update the SmPC and to send a DHPC, and the determinant was the level of concern. For the second study aim, the outcome was the concern regarding the safety issues, and the determinants were the attributes of the safety issue, the demographic and professional characteristics, and the regulators’ attitudes (Fig. 1).

Overview of the study aims, outcomes, and determinants. 1Aim A, to explore to what extent regulators’ opinions regarding the need to communicate through updating the SmPC or sending a DHPC is influenced by regulators’ concern about the safety issue. 2Aim B, to assess whether regulators’ concerns are influenced by certain characteristics of the safety issue, demographic and professional characteristics of the regulators, and regulators’ attitudes. SmPC summary of product characteristics, DHPC direct healthcare professional communication

We used descriptive statistics for the analysis of the demographic and professional characteristics, the regulators’ attitudes, the benefit-risk evaluation, and the level of concern per scenario, as well as for the calculation of the proportion of participants who considered it necessary to communicate the risk per scenario. Only those participants who completed at least one question regarding their level of concern towards the safety issue, their opinion on the need to update the SmPC, or the need to send a DHPC were included in the study.
To determine the influence of the level of concern on the need to update the SmPC or to send a DHPC, we fitted generalised linear mixed-effects models (GLMMs) with a binomial distribution and a logit link function. In these models, the level of concern was included as a fixed effect and by-subject random intercepts and slopes for the level of concern were included as random effects. Results regarding the effect of the level of concern on the need to communicate are presented as the odds ratios of updating the SmPC or sending a DHPC for a 10 percentage-point increase in the level of concern and graphically by plotting the estimated population-level probabilities of updating the SmPC or sending a DHPC against the level of concern.
To assess the effects of the attributes of the safety issue, demographic and professional characteristics, and regulators’ attitudes on the level of concern, we fitted multiple linear mixed effects models. We began by fitting a crude model in which the attributes of the safety issue were included as the only fixed effects and by-subject random intercepts and slopes for the attributes of the safety issue were included as the random effects. Subsequently, we fitted separate follow-up models in which, while maintaining the fixed and random effects of the crude model, we added the other determinants (i.e., demographic and professional characteristics and regulators’ attitudes) one by one as fixed effects. We tested for the determinants’ main effect as well as all possible two-way interactions between each determinant and the attributes of the safety issue. We performed backward elimination to stepwise remove all non-significant interaction terms. Results are presented as estimated marginal means (also known as least-squares means), which reflect the predicted outcome for each level of a factor averaged over all possible combinations of the levels of the other factors in the model. They were unstratified for the crude model and stratified by demographic and professional characteristics, and by regulators’ attitudes for the follow-up models. The groups of categorical variables were pre-defined by definition (e.g., women vs. men), and groups of the continuous variables were created using the score of the variable at the 25th, 50th and 75th percentiles. Further details regarding the estimated marginal means as well as the regression coefficients of each model are presented in ESM 2.
Because the sampling scheme per country could have resulted in data clusters per country, we generated a multi-level model with observations grouped by individuals nested in country. These results showed no indication of clusters (ESM 2); therefore, no adjustments for the sampling scheme were made in the statistical analysis.
The analyses were performed in R version 4.0.2 (R Foundation for Statistical Computing, Vienna, Austria; URL https://www.R-project.org/) with the packages lme4, emmeans and lmerTest [32 –34 ]. Statistical significance was indicated by p-values less than 0.05. Figures were generated in R and Microsoft Excel® 2010 (Microsoft Corp., Redmond, WA, USA).

Aged rats received a subcutaneous injection of saline (0.9% NaCl) or methionine (200 mg/kg; Sigma-Aldrich, St. Louis, Missouri, USA) twice a day (12-h interval) for 30 days. This dosage was previously shown to induce global DNA hypermethylation [23 (link)]. For the RG108 experiment, bilaterally cannulated young rats (ACSF-SHAM: n=12; ACSF-DBS: n=12; RG108-SHAM: n=14; RG108-DBS: n=12) were infused with either RG108 (Axon Medchem) or artificial cerebral spinal fluid (ACSF) for 30 days at a dosage previously shown to reduce DNA methylation [24 (link)]. RG108 in 20% DMSO was diluted to 200 ng/µL in ACSF. Drugs (2 µL) were infused into the dHPC using a Hamilton syringe connected to the internal cannula through polyethylene tubing (Protech international, Texas, USA) at a rate of 0.5 µL/min over 4 min. The internal cannula was left inside the guide cannula for an additional 3 min to ensure proper diffusion of the infused drug.

This assay was performed as previously described [6 (link), 8 (link), 29 (link), 30 (link)]. Animals were decapitated on day 30 after receiving 1-h electrical stimulation. The dHPC was dissected and total RNA was extracted using TRIzol reagent (Cat# TR118, Molecular Research Center Inc., Ohio, USA). RNA concentration and purity were determined using a NanoDrop spectrophotometer (Thermo Fisher Scientific, USA) through calculating the ratio of optical density at wavelengths between 260nm and 280nm. 7µl of RNA (600-800 ng in total) was used for cDNA synthesis using a PrimeScript™ RT reagent kit with gDNA eraser (Cat# RR047B, Takara Bio USA, California, USA) according to the instructions from manufacturer. Briefly, the RNA mixture was incubated with gDNA eraser and eraser buffer at 42°C for 2 min, followed by incubation in reverse transcription buffer, enzyme and primer mix at 37°C for 15 min, and finally with incubation at 85°C for 5 s to produce the final cDNA synthesis mixture. Efficiency of primers was validated using the diluted cDNA series measured between 90-110%. Real-time PCR was performed on a Roche LightCycler 480 II (Roche Diagnostics). Relative gene expressions were analyzed using the 2-DDCT method relative to the expression of SAL-SHAM group (for aged animal experiments) or ACSF-SHAM group (for young animal experiments) [29 (link), 30 (link)] (Table 1).
