Dynamic disorder of the lipid bilayer presents a challenge for establishing structure-function relationships in membranous systems. The resulting structural heterogeneity is especially evident for peripheral and spontaneously inserting membrane proteins, which are not constrained by the well-defined transmembrane topology and exert their action in the context of intimate interaction with lipids. Here, we propose a concerted approach combining depth-dependent fluorescence quenching with Molecular Dynamics simulation to decipher dynamic interactions of membrane proteins with the lipid bilayers...

The assembly and accumulation of α-synuclein fibrils are implicated in the development of several neurodegenerative disorders including multiple system atrophy and Parkinson's disease. Pre-existing α-synuclein fibrils can recruit and convert soluble non-fibrillar α-synuclein to the fibrillar form similar to what is observed in prion diseases. This raises concerns regarding attachment of fibrillary α-synuclein to medical instruments and subsequent exposure of patients to α-synuclein similar to what has been observed in iatrogenic transmission of prions...

BACKGROUND: Surgery for athletic pubalgia usually consists in abdominal wall repair combined with routine bilateral adductor tenotomy. We currently confine the surgical procedure to the injured structure(s) (abdominal wall only, adductor tendon only, or both) to limit morbidity and expedite recovery. Outcomes of this à la carte approach are unclear. The objectives of this retrospective study were to determine the return to play (RTP) time, evaluate the potential influence of injury location, and assess the frequency of recurrence or contralateral involvement...

Forced displacements and their psychosocial consequences in adolescent refugees and their families have received increasing attention in recent years. Although supportive family relations play a key role in buffering the impact of traumatization in adolescents, parental ability to provide such is often subject to extreme pressure. Under conditions of forced dislocation and fear, maladaptive interpersonal strategies in the parent-child relationships may develop, contributing to the onset of psychopathology. We explore new aspects of attachment-related issues for the understanding and treatment of adolescent refugees who have experienced multiple traumas in their childhood...

Anxiety disorders are among the most prevalent psychiatric disorders in youth; however, progress in treatment for childhood anxiety has stalled over the past decade. The National Institute of Mental Health (NIMH) Research Domain Criteria (RDoC) project represents a shift toward a dimensional and interdisciplinary approach to psychiatric disorders; this shift can reframe developmental psychopathology for childhood anxiety and facilitate novel advances in its classification and treatment. Here we highlight constructs in the Systems for Social Processes and the Negative Valence System domains of RDoC, as they relate to childhood anxiety disorders...

PURPOSE: To test the feasibility of a cell therapy approach to treat corneal endothelial (CE) disorders using an in vitro model of human corneal decompensation. METHODS: A CE decompensation model was established by removal of the Descemet membrane/endothelium complex from cadaveric human corneas in an air interface organ culture system (group 2) and compared with normal corneas (group 1). The posterior stroma of decompensated corneas was seeded with immortalized human corneal endothelial cells (HCEC-12) in group 3 and passage 0 primary human CE cells in group 4 corneas...

BACKGROUND: Hutchinson-Gilford progeria syndrome (HGPS) is a rare premature aging disorder with significant oral and dental abnormalities. Clinical symptoms include various features of accelerated aging such as alopecia, loss of subcutaneous fat, bone abnormalities, and premature cardiovascular disease. In addition, children with HGPS have been observed to suffer from generalized gingival recession. Whether periodontal manifestations associated with this syndrome are the results of changes in the oral flora is unknown...

OBJECTIVES: Within a randomized controlled trial contrasting the outcome of manualized cognitive-behavioral (CBT) and short term psychodynamic therapy (PDT) compared to a waiting list condition (the SOPHO-Net trial), we set out to test whether self-reported attachment characteristics change during the treatments and if these changes differ between treatments. RESEARCH DESIGN AND METHODS: 495 patients from the SOPHO-Net trial (54.5% female, mean age 35.2 years) who were randomized to either CBT, PDT or waiting list (WL) completed the partner-related revised Experiences in Close Relationships Questionnaire (ECR-R) before and after treatment and at 6 and 12 months follow-up...

Over a lifetime, humans build relationships with family, friends, and partners that are critically important for our mental and physical health. Unlike commonly used laboratory mice and rats, Microtine rodents provide a unique model to study the neurobiology underlying pair bonding and the selective attachments that form between adults. Comparisons between monogamous prairie voles and the closely related, but non-monogamous meadow and montane voles, have revealed that brain-region-specific neuropeptide receptor patterning modulates social behavior between and within species...

Tendons and ligaments are dense fibrous connective tissues mainly composed of type I collagen, aligned in highly ordered arrays along the axis of the tendon and ligament. The enthesis is defined as the attachment site of a tendon, ligament, joint capsule, or fascia to bone. During morphogenesis, the cell population co-expressing Scleraxis(Scx)and the SRY-box containing gene 9(Sox9)contributes to the formation of fibrocartilaginous entheses. Scx regulates tendon and ligament maturation, while Sox9 is a key regulatory factor for cartilage formation...

Cartilage injury remains one of the common clinical problems due to its limited regeneration capacities. Meniscectomy commonly performed for meniscus injury leads to osteoarthritis, but the indication of meniscus repair is limited. We have identified that synovial mesenchymal stem cells(MSCs)are superior to MSCs derived from other tissues in proliferation capacity and in vitro/in vivo chondrogenic potentials. When suspension of synovial MSCs was placed on the cartilage defect for 10 minutes, 60% of the cells attached to the defect site...

Cripto-1 (TDGF1) is a multifunctional signaling factor that stimulates cellular effects including proliferation, migration, survival, EMT and angiogenesis to regulate embryogenesis, tissue homeostasis and tumorigenesis. Those cell behaviors are also associated with implantation of the embryo into the uterine wall and this led us to investigate the role of embryo-derived Cripto in embryo attachment and implantation. We show here that Cripto and its signaling mediator GRP78 are uniquely localized to embryo implantation sites...

Earlier studies report that although people with borderline personality disorder (BPD) experience symptom reduction in the long term, they continue to have difficulties in work recovery. This nationwide 9-year register-based study (N = 67,075) investigated the long-term labor-market attachment of all individuals diagnosed with BPD during first admission to Danish mental health services in comparison with other psychiatric disorders. Controlling for baseline characteristics and co-occurring secondary psychiatric diagnoses, the BPD group had 32% lower odds (OR = 0...

This paper investigates the role of caregiver mental health and parenting practices as predictors of attachment in children with intellectual disability/developmental delay, comparing between children with ASD (n = 29) and children with other developmental disabilities (n = 20). Parents reported that children with ASD had high levels of anxiety and stress, and attachment insecurity in children (less closeness and more conflict in attachment relationships, and more inhibited attachment behaviours) compared with children with other developmental disabilities...

The nuclear pore complex (NPC) is the gatekeeper for nuclear transport in eukaryotic cells. A key component of the NPC is the central shaft lined with intrinsically disordered proteins (IDPs) known as FG-Nups, which control the selective molecular traffic. Here, we present an approach to realize artificial NPC mimics that allows controlling the type and copy number of FG-Nups. We constructed 34 nm-wide 3D DNA origami rings and attached different numbers of NSP1, a model yeast FG-Nup, or NSP1-S, a hydrophilic mutant...
