Objective: Families play a pivotal role in supporting one another during cancer. Research suggests that supportive care interactions between patients and their caregivers can have a positive effect on the physical health and well-being of both members of the dyad. However, few studies have investigated how patient and caregiver personality characteristics intersect with their perceptions of supportive exchanges. Adopting an attachment theory perspective, our aim was to examine the dyadic effects of patient and caregiver attachment orientations on mutually supportive care.
Methods: Patients (n = 103) receiving cancer care and their caregivers (n = 99) completed a survey that comprised measures of attachment orientations (Experiences in Close Relationships Modified scale), and mutually supportive care (Shared Care Inventory, SCI-3): communication, decision-making and reciprocity.
Results: Actor-Partner Interdependence Models (APIMs) were used to examine the association between participants' attachment orientations on their own (actor effects) SCI-3 outcomes and those of the other person within the dyad (partner effects). Across the APIMs, the tendency was for an inverse relationship between attachment (anxious and avoidant orientations) and mutually supportive care. Inspection of the effects and dyadic patterns supported actor and couple models.
Conclusions: Using a dyadic approach, it was possible to study both intrapersonal and interpersonal effects. Our findings point to interdependence within the cancer caregiving relationship and underscore the importance of considering how individual and relational ways of responding influence support. Attachment theory provides a framework for explaining the observed relationships and a basis for therapeutic intervention.

The design and development of advanced surgical sutures with appropriate structure and abundant bio-functions are urgently required for the chronic wound closure and treatment. In this study, an integrated technique routine combining modified electrospinning with hot stretching process was proposed and implemented to fabricate poly(L-lactic acid) (PLLA) nanofiber sutures, and the Salvia miltiorrhiza Bunge-Radix Puerariae herbal compound (SRHC) was encapsulated into PLLA nanofibers during the electrospinning process to enrich the biofunction of as-generated sutures. All the PLLA sutures loading without or with SRHC were found to exhibit bead-free and highly-aligned nanofiber structure.

Calcium binding to troponin triggers the contraction of skeletal and heart muscle through structural changes in the thin filaments that allow myosin motors from the thick filaments to bind to actin and drive filament sliding. Here, we review studies in which those changes were determined in demembranated fibres of skeletal and heart muscle using fluorescence for in situ structure (FISS), which determines domain orientations using polarised fluorescence from bifunctional rhodamine attached to cysteine pairs in the target domain. We describe the changes in the orientations of the N-terminal lobe of troponin C (TnC) and the troponin IT arm in skeletal and cardiac muscle cells associated with contraction and compare the orientations with those determined in isolated cardiac thin filaments by cryo-electron microscopy.

The ubiquitous trans-translation system as well as several alternative rescue factors (Arfs) are responsible for rescuing the stalled ribosomes caused by truncated mRNAs that lack the stop codons. To date, protein release factor homolog (PrfH) is the only factor known to rescue the stalled ribosome damaged by ribotoxins.

Synthetic ssDNA oligonucleotides hold great potential for various applications, including DNA aptamers, DNA digital data storage, DNA origami, and synthetic genomes. In these contexts, precise control over the synthesis of the ssDNA strands is essential for generating combinatorial sequences with user-defined parameters. Desired features for creating synthetic DNA oligonucleotides include easy manipulation of DNA strands, effective detection of unique DNA sequences, and a straightforward mechanism for strand elongation and termination.

Background: Traumatic childbirth can lead to childbirth-related posttraumatic stress symptoms (CB-PTSS). Although underexplored, prenatal couple relationship satisfaction and romantic attachment orientations are modifiable factors that may increase or mitigate the risk of CB-PTSS after a traumatic childbirth experience.
Objectives: This study examined (1) the associations between prenatal couple relationship satisfaction and romantic attachment, traumatic childbirth and CB-PTSS; (2) whether prenatal couple relationship satisfaction moderates the association between traumatic childbirth and CB-PTSS; and (3) whether the interaction between prenatal couple relationship satisfaction and romantic attachment moderates the association between traumatic childbirth and CB-PTSS.
