title: High-resolution tandem mass spectrometry dataset in leaves of foxglove plants

description: The first pair of true leaves from 5-week-old Digitalis seedlings grown under a 16-hour light period at 25 °C was collected in biological triplicates. 80% Methanol extract of freeze-dried leaf samples from Digitalis lanata and Digitalis purpurea were filtered through a 0.45 µl filter before injection to the LC/MS/MS system. The extract was first separated on a C18 reverse-phase column before enteringth Q-ExactiveTM analyser. A selected ion monitoring with MS2 (SIM-ddMS2) was used for data acquisition.

title: Core components of the nuclear pore bind distinct states of chromatin and contribute to Polycomb repression Gozalo; Duke et al.

description: Abstract: Interactions between the genome and the nuclear pore complex (NPC) have been implicated in multiple gene regulatory processes, but the underlying logic of these interactions remains poorly defined. Here, we report high-resolution chromatin binding maps of two core components of the NPC, Nup107 and Nup93, in Drosophila cells. Our investigation uncovered differential binding of these NPC subunits, where Nup107 preferentially targets active genes while Nup93 associates primarily with Polycomb-silenced regions. Comparison to Lamin-associated domains (LADs) revealed that NPC binding sites can be found within LADs, demonstrating a linear binding of the genome along the nuclear envelope. Importantly, we identified a functional role of Nup93 in silencing of Polycomb target genes and in spatial folding of Polycomb domains. Our findings lend to a model where different nuclear pores bind different types of chromatin via interactions with specific NPC sub-complexes, and a subset of Polycomb domains is stabilized by interactions with Nup93.

title: BIU Couples Support and EA Study, 2013

description: This is a multi-method longitudinal dyadic study of cohabiting romantic couples, aimed at examining dyadic support and empathic accuracy. Data were collected between June 2012-July 2013. We recruited 86 heterosexual couples (mean age 26.7 [SD=3.9] and 29.3 [SD=4.4], for women and men respectively). These couples were in romantic relationships for an average of 4.6 years (SD=2.9) and were cohabiting for an average of 3.0 (SD=2.5). In their first lab visit, couples completed background questionnaires and were instructed in the use of a web-based diary. Then, each evening, for 35 days, they were asked to fill out the diary questionnaire. The retention and adherence rates obtained in the main study were exceptionally high (only 6 couples dropped out, and participates completed an average of 34.6 diary entries, of which an average of 29.7 entries were fully compliant with our scheduling requests). Four and twelve months after the completion of the diary period, they were emailed a link to a follow up questionnaire (86.25% and 75.6% of individuals completed the first and second follow-ups, respectively).

title: Growth in Early Marriage (GEM) Project: A Longitudinal Study of Newly Married Couples, 2015

description: Newlywed couples (opposite sex) were recruited primarily from marriage license records (for more details, see Beck, Pietromonaco, DeBuse, Powers, Sayer, 2013). Data were collected from December 2008 – June 2015. Eligibility criteria at Time 1 were that partners were between 18-50 years, in their first marriage, had no children, and could attend a lab session within the first 7 months of their marriage, and that wives were not pregnant. Couples attended a lab session at three time points over the first 3-4 years of marriage. Sample included 225 couples at Time 1; 201 couples at Time 2 (about 19 mos after first visit); 180 couples at Time 3 (about 37 mos after first visit). At each session, couple members provided saliva samples at five time points before, during and after a discussion of a major area of disagreement in their relationship and one sample at home (provided at the same time of day as their first lab sample). In the lab, couples talked for 15 minutes about a disagreement while being digitally recorded. All conflict discussions at each of the three waves were coded by trained observers using the Secure Base Coding Scheme (Crowell et al., 2002) and the Rapid Marital Interaction Coding System (Heyman, 2004). At the end of the session, couples talked for 5 minutes about what they liked about their partner and relationship, and this interaction was digitally recorded. Questionnaires were completed before and after the discussion at each session. This research has been approved by the University of Massachusetts, Amherst Institutional Research Board.

title: Data for: Effect of Ti2Cu precipitation on antibacterial property of Ti–5Cu alloy

description: Michelle Oyen Editor-in-Chief Materials Science and Engineering: C Dear Editor: I wish to submit a research paper for publication in Materials Science and Engineering: C, titled “Effect of Ti2Cu precipitation on antibacterial property of Ti–5Cu alloy.” The paper was coauthored by Ju-Hui Wu, Chih-Yeh Chao, and Yen-Hao Chang. This study set out to examine the antibacterial effects of Ti alloys to which Cu had been added. We found that the solid-solution treatment of a Ti–5Cu alloy failed to provide an acceptable level of antibacterial activity, but the presence of nano-scale Ti2Cu precipitates led to the alloy exhibiting a relatively high antibacterial activity of &gt; 90%. We believe that our study makes a significant contribution to the literature because this would provide a means of overcoming the serious problem of bacterial infection that remains an issue with the implantation of Ti prostheses. Further, we believe that this paper will be of interest to the readership of your journal because the relationship between heat treatment and the antibacterial property has not been explored in Ti based antibacterial materials. The aim of this work is to study the effects of heat treatment on microstructure and antibacterial property of a Ti-5Cu alloy in order to produce an optimal antibacterial material for clinic application. This manuscript has not been published or presented elsewhere in part or in entirety and is not under consideration by another journal. We have read and understood your journal’s policies, and we believe that neither the manuscript nor the study violates any of these. There are no conflicts of interest to declare. Thank you for your consideration. I look forward to hearing from you.
