Effects of adipose allograft matrix on viability of humeral head cartilage and rotator cuff tendon.

Background: Rotator cuff repairs may fail because of compromised blood supply, suture anchor pullout, or poor fixation to bone. To augment the repairs and promote healing of the tears, orthobiologics, such a platelet-rich plasma (PRP), and biologic scaffolds have been applied with mixed results. Adipose allograft matrix (AAM), which recruits native cells to damaged tissues, may also be a potential treatment for rotator cuff tears.

Plasma levels of anti phosphocholine IgM antibodies are negatively correlated with bone mineral density in humans.

Phosphatidylcholine is a ubiquitous phospholipid. It contains a phosphocholine (PC) headgroup and polyunsaturated fatty acids that, when oxidized, form reactive oxidized phospholipids (PC-OxPLs). PC-OxPLs are pathogenic in multiple diseases and neutralized by anti-PC IgM antibodies.

Warming-induced changes in seasonal priority effects drive shifts in community composition.

Shifting community assembly dynamics are an underappreciated mechanism by which warming will alter plant community composition. Germination timing (which can determine the order in which seedlings emerge within a community) will likely shift unevenly across species in response to warming. In seasonal environments where communities reassemble at the beginning of each growing season, changes in germination timing could lead to changes in seasonal priority effects, and ultimately community composition.

Neurophysiological Markers of Regulation Success in Everyday Life in Depression.

Background: Self-regulation often is disrupted in depression and is characterized by negative affect and inflexible parasympathetic responses. Yet, our understanding of brain mechanisms of self-regulatory processes largely has been limited to laboratory contexts. Measuring individual differences in self-regulatory processes in everyday life - and their neural correlates - could inform our understanding of depression phenotypes and reveal novel intervention targets that impact everyday functioning.

The impact of neoadjuvant therapy in patients with left-sided resectable pancreatic cancer: an international multicenter study.

Purpose: To assess the association between neoadjuvant therapy and overall survival (OS) in patients with left-sided resectable pancreatic cancer (RPC) compared to upfront surgery.

Background: Left-sided pancreatic cancer is associated with worse OS compared to right-sided pancreatic cancer. Although neoadjuvant therapy is currently seen as not effective in patients with RPC, current randomized trials included mostly patients with right-sided RPC.

Objective: To assesses the effect of prophylactic antibiotics on the duration of latency in individuals with previable prelabor rupture of membranes.

Real-time control of radiofrequency ablation using three-dimensional ultrasound echo decorrelation imaging in normal and diseasedhuman liver.

Ultrasound echo decorrelation imaging can successfully monitor and control thermal ablation of animal liver and tumor tissue ex vivo and in vivo. However, normal and diseased human liver has substantially different physical properties that affect echo decorrelation. Here, effects of human liver tissue condition on ablation guidance by three-dimensional echo decorrelation imaging are elucidated in experiments testing closed-loop control of radiofrequency ablation (RFA) in normal and diseased human liver tissue ex vivo.

Using the Key Characteristics Framework to Unlock the Mysteries of Aryl Hydrocarbon Receptor-Mediated Effects on the Immune System.

Initially discovered for its role mediating the deleterious effects of environmental contaminants, the aryl hydrocarbon receptor (AHR) is now known to be a crucial regulator of the immune system. The expanding list of AHR ligands includes synthetic and naturally derived molecules spanning pollutants, phytochemicals, pharmaceuticals, and substances derived from amino acids and microorganisms. The consequences of engaging AHR vary, depending on factors such as the AHR ligand, cell type, immune challenge, developmental state, dose, and timing of exposure relative to the immune stimulus.

Effectiveness of a program director for osteopathic medical education to support osteopathic recognition at a training site with multiple programs.

Context: With the advent of the Single Accreditation System (SAS) within the Accreditation Council for Graduate Medical Education (ACGME), few programs have achieved Osteopathic Recognition (OR) status to date. OR is an accreditation that graduate medical education (GME) programs can achieve to distinctly acknowledge the additional focus on osteopathic training. There is an effort by national osteopathic organizations to determine barriers for programs to achieve OR and what innovative methods might help overcome them.

Methods: The study consisted of six stages: preparation of femur from a healthy dog cadaver; digitalization of the bone through a 3D scanner and creation of the base model; creation of a 3D AMDFD based on the image of the base model, 3D modeling carried out to reproduce five different types of diaphyseal fractures; printing the models produced on a 3D printer with a thermoplastic material; insertion of neodymium magnets in the fracture line to allow the assembly and disassembly of the parts; and radiography of 3D AMDFD in lateromedial and craniocaudal positions.

Results: The base model and 3D AMDFD had high precision in the replication of bone structures, like the bone in natura.

From "isolation" to "me-time": linguistic shifts enhance solitary experiences.

Spending time alone is a virtually inevitable part of daily life that can promote or undermine well-being. Here, we explore how the language used to describe time alone - such as "me-time", "solitude", or "isolation" - influences how it is perceived and experienced. In Study 1 ( = 500 U.

Spine-Abductor Syndrome: Novel Associations Between Lumbar Spine Disease and Hip Gluteal Muscle Pathology.

Background: Risk factors for gluteal tears include age-related deterioration, female sex, and increased body mass index. As the literature that supports the sagittal relationship between the lumbar spine and the hip is increasing, there may be a parallel relationship between the perturbations in spinopelvic alignment caused by lumbar spine disease and gluteal muscle tears. Because no prior studies other than single-institution series have reported on this phenomenon, we investigated spine-abductor syndrome at the population level.

Technical considerations of cardiac computed tomography in children.

Cardiac computed tomography angiography (CTA) is a valuable tool in the assessment of congenital and acquired cardiac disease in children. The goal of cardiac CTA is to produce images that are free of motion and provide sufficient characterization of the anatomy in question. Given the complexity of pediatric patient characteristics, including patient size, heart rate, breath-holding capability, and variant anatomy, cardiac CTA technique must be individualized to the patient as well as the indication to answer the clinical question while also minimizing radiation exposure.
