The Impact of Electronic Medical Record Implementation on Labor Cost and Productivity at an Outpatient Orthopaedic Clinic.

Widespread adoption of electronic medical record (EMR) systems is increasing. EMR implementation can be costly and typically requires workflow redesign. To our knowledge, no studies to date have examined the impact of EMR implementation using advanced cost accounting methods or the impact of its implementation on orthopaedic surgeons in an outpatient setting.


FAK- and YAP/TAZ dependent mechanotransduction pathways are required for enhanced immunomodulatory properties of adipose-derived mesenchymal stem cells induced by aligned fibrous scaffolds.

Adipose-derived mesenchymal stem cells (ASCs) represent an excellent candidate for tissue engineering due to their multipotency and paracrine functions. Physical cues provided by the scaffolds have been shown to direct a variety of cellular behaviors of ASCs; however, their effects on the paracrine functions of ASCs, especially immunomodulatory functions, remain largely unexplored. Thus, PLLA electrospun fibrous scaffolds, with fibers oriented either randomly or aligned, were used as a model to investigate ...

Mean 6-Year Follow-up of Magnetically Controlled Growing Rod Patients With Early Onset Scoliosis: A Glimpse of What Happens to Graduates.

There is no agreement on frequency of distractions of magnetically controlled growing rods (MCGRs) but more frequent and smaller amounts of distractions mimic physiological spine growth. The mid- to long-term follow-up and management at skeletal maturity is unknown.


Obesity-Activated Adipose-Derived Stromal Cells Promote Breast Cancer Growth and Invasion.

Obese women diagnosed with breast cancer have an increased risk for metastasis, and the underlying mechanisms are not well established. Within the mammary gland, adipose-derived stromal cells (ASCs) are heterogeneous cells with the capacity to differentiate into multiple mesenchymal lineages. To study the effects of obesity on ASCs, mice were fed a control diet (CD) or high-fat diet (HFD) to induce obesity, and ASCs were isolated from the mammary glands of lean and obese mice. We observed that obesity incre...

Isolating and Characterizing Adipose-Derived Stem Cells.

The research and application of regeneration medicine will require a reliable source of stem cells. Adipose tissue has proven to be an easily accessible and rich source of adult stem cells, termed adipose-derived stem cells (ASCs). ASCs have the most important advantage over stem cells from other available sources. There is no other human tissue as abundant as adipose tissue, making it possible to isolate adequate numbers of ASCs for potential clinical applications. Here, we describe detailed methods for is...

Characterization of Senescence of Human Adipose-Derived Stem Cells After Long-Term Expansion.

Since the 1980s, adipose-derived stem cells (ASCs) have become a powerful and potential source for stem cell-based therapy, regenerative medicine, and even drug delivery in cancer treatment. The development of off-the-shelf mesenchymal stem cells (MSCs), including ASCs, has rapidly advanced in recent years with several clinical trials and approved products. In this technology, ASCs should be expanded long term in order to harvest higher cell number. In this study, senescence of ASCs after long-term expansio...

Ascorbic acid prevents cellular uptake and improves biocompatibility of chitosan nanoparticles.

Chitosan nanoparticles have many applications, such as gene and drug delivery, due to their biocompatibility. Chitosan nanoparticles are currently produced by dissolution in acetic acid that affects the biocompatibility at acidic pH. Here, we synthesized and characterized chitosan (CS) and ascorbate chitosan (AsCS) nanoparticles and investigated their cytotoxic effects, internalization, and distribution in the human colon carcinoma cell line using confocal laser scanning microscopy (CLSM). The CS and AsCS n...

Comparison of the regenerative cytokine profile of adipose-derived stromal cells (ASCs) harvested via abdominoplasty, suction-assisted liposuction (SAL) and ultrasound-assisted liposuction (UAL).

Mesenchymal stem cells are already used in numerous areas of medicine. In the field of plastic surgery, the main focus of recent research has been to utilise adipose-derived stromal cells (ASCs), mainly harvested via liposuction. The ability to release regenerative cytokines is supposed to be the key mechanism for the therapeutic efficacy of ASCs. There are currently a variety of methods and devices in clinical use for harvesting lipoaspirate and consequently ASCs. For most of these devices, the effect on t...

Alterations of MEK1/2-ERK1/2, IFNγ and Smad2/3 associated Signalling pathways during cryopreservation of ASCs affect their differentiation towards VSMC-like cells.

Vascular smooth muscle cells (VSMCs) play essential roles in regulating blood vessel form and function and they are required for vascular tissue regeneration. Multipotent adipose derived stromal cells (ASCs) can be differentiated into VSMC-like cells, which can be used as a potential VSMC source for the development of vascular tissue. However, the effects of cryopreservation on the differentiation of ASCs towards VSMCs are poorly studied to date. This study compared fresh ASCs (FA) vs. cryopreserved ASCs (C...

In Vitro and In Vivo Osteogenic Differentiation of Human Adipose-Derived Stromal Cells.

Adipose-derived stromal cells (ASCs) are a promising population of cells that may be useful for the regeneration of human tissue defects. ASCs are capable of forming bone tissue in vitro and in vivo. Further work is required to determine the optimal conditions that will allow human ASCs to regenerate tissue in clinically significant tissue defects. Here we present three experimental protocols that are indispensable for the study of ASC osteogenic activity.

Acceleration of diabetic wound healing with adipose-derived stem cells, endothelial-differentiated stem cells, and topical conditioned medium therapy in a swine model.

The purpose of our study was to investigate the effect of adipose-derived stem cells (ASCs), endothelial-differentiated ASCs (EC/ASCs), and various conditioned media (CM) on wound healing in a diabetic swine model. We hypothesized that ASC-based therapies would accelerate wound healing.

Immunophenotyping and transcriptional profiling of in vitro cultured human adipose tissue derived stem cells.

Adipose-derived stem cells (ASCs) have become an important research model in regenerative medicine. However, there are controversies regarding the impact of prolonged cell culture on the ASCs phenotype and their differentiation potential. Hence, we studied 10 clinical ASCs replicates from plastic and oncological surgery patients, in six-passage FBS supplemented cultures. We quantified basic mesenchymal cell surface marker transcripts and the encoded proteins after each passage. In parallel, we investigated ...

Platelet-derived growth factor-AA is a substantial factor in the ability of adipose-derived stem cells and endothelial progenitor cells to enhance wound healing.

Nonhealing wounds with various forms of complications have been a major challenge for patients with different diseases, and few data are available regarding the clinical significance of platelet-derived growth factor-AA (PDGF-AA) in the enhanced wound healing with stem cells, and the precise molecular mechanism remains unclear. The study aims to investigate the role of PDGF-AA in adipose-derived stem cells (ASCs) and endothelial progenitor cells (EPCs) enhancing wound healing. In this study, ASCs and EPCs w...

Endothelin-1 differentially directs lineage specification of adipose- and bone marrow-derived mesenchymal stem cells.

Blood vessels composed of endothelial cells (ECs) contact with mesenchymal stem cells (MSCs) in different tissues, suggesting possible interaction between these 2 types of cells. We hypothesized that endothelin-1 (ET1), a secreted paracrine factor of ECs, can differentially direct the lineages of adipose-derived stem cells (ASCs) and bone marrow-derived MSCs (BMSCs). Predifferentiated ASCs and BMSCs were treated with ET1 for 2 cell passages and then induced for multilineage differentiation. Our results show...

Immunophenotypic characterization of CSF B cells in virus-associated neuroinflammatory diseases.

Intrathecal antibody synthesis is a well-documented phenomenon in infectious neurological diseases as well as in demyelinating diseases, but little is known about the role of B cells in the central nervous systems. We examined B cell and T cell immunophenotypes in CSF of patients with HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) compared to healthy normal donors and subjects with the other chronic virus infection and/or neuroinflammatory diseases including HIV infection, multiple scle...

The Suppression Effect of Dendritic Cells Maturation by Adipose-derived Stem Cells through TGF-β1 Related Pathway.

Our previous studies demonstrated that adipose-derived stem cells (ASCs) could modulate regulatory T cells (Treg) and prolong hind-limb allotransplant survival in vitro and in vivo. Dendritic cells (DC) play a pivotal role in innate and adaptive immunity. The aim of this study is to investigate the underlying mechanism of ASCs in modulating DC maturation.

Involvement of acetyl-CoA-producing enzymes in the deterioration of the functional potential of adipose-derived multipotent cells from subjects with metabolic syndrome.

The expansion capacity of white adipose tissue influences the distribution of fat depots in the body, the visceral accumulation of which is linked to metabolic syndrome, regardless of the degree of obesity of the subjects. Alterations in the adipose tissue-derived mesenchymal stem cells (ASCs) may contribute to the adipose tissue remodeling associated with metabolic syndrome and impact the regional distribution of adipose tissue by generating inherently dysfunctional adipocytes. Here we examine the expressi...

Adipose-derived stem cell-mediated paclitaxel delivery inhibits breast cancer growth.

Breast cancer represents the main malignancy in women and autologous fat grafting is a diffuse procedure in the management of post-surgical breast defects causing patients' psychosocial problems, with high costs for the public health. Recently, beneficial effects of fat grafting during post-surgical breast reconstruction have been amplified from the enrichment with human adipose-derived stem cells (ASCs) present in the stromal vascular fraction (SVF) of adult adipose tissue isolated during intraoperatory pr...

Reward-associated distractors can harm cognitive performance.

When people carry out cognitive tasks, they sometimes suffer from distractions, that is, drops in performance that occur close in time to task-irrelevant stimuli. In this research, we examine how the pursuit of rewards contributes to distractions. In two experiments, participants performed a math task (in which they could earn monetary rewards vs. not) while they were exposed to task-irrelevant stimuli (that were previously associated with monetary rewards vs. not). In Experiment 1, irrelevant cues that wer...

Osteogenic Differentiation Modulates the Cytokine, Chemokine, and Growth Factor Profile of ASCs and SHED.

Great efforts have been made to improve bone regeneration techniques owing to a growing variety of sources of stem cells suitable for autologous transplants. Specifically, adipose-derived stem cells (ASCs) and stems cells from human exfoliated deciduous teeth (SHED) hold great potential for bone tissue engineering and cell therapy. After a preliminary characterization of the main biomolecules ASCs and SHED released in their conditioned media, cells were kept both in normal and osteo-inducing conditions. Con...

Limited Endothelial Plasticity of Mesenchymal Stem Cells Revealed by Quantitative Phenotypic Comparisons to Representative Endothelial Cell Controls.

Considerable effort has been directed toward deriving endothelial cells (ECs) from adipose-derived mesenchymal stem cells (ASCs) since 2004, when it was first suggested that ECs and adipocytes share a common progenitor. While the capacity of ASCs to express endothelial markers has been repeatedly demonstrated, none constitute conclusive evidence of an endothelial phenotype as all reported markers have been detected in other, non-endothelial cell types. In this study, quantitative phenotypic comparisons to r...

Plasma cells: the programming of an antibody-secreting machine.

Antibodies are an essential component of our immune system, underpinning the effectiveness of both the primary immune response to microbial pathogens and the protective and long-lived immunity against re-challenge. All antibodies are produced by relatively rare populations of plasmablasts and plasma cells, collectively termed antibody-secreting cells (ASCs). It is now apparent that ASCs are unique in the body in terms of their gene expression program and metabolic pathways that enable these cells to have an...

Orthopaedic Resident Use of an Electronic Medical Record Template Does Not Improve Documentattion for Pediatric Supracondylar Humerus Fractures.

Pediatric supracondylar humerus fractures are associated with a high incidence of nerve injury. Therefore, it is imperative that documentation be complete and accurate. This investigation compares orthopaedic resident history and physical (H&P) documentation of pediatric supracondylar fractures for completeness and accuracy with and without the use of an electronic medical record template.

Cheeses Made from Raw and Pasteurized Cow's Milk Analysed by an Electronic Nose and an Electronic Tongue.

Cheese prepared from whole milk, raw and pasteurized, were analysed by an electronic nose based on piezoelectric quartz crystals and an electronic tongue based on potentiometric sensors, immediately after their preparation and along ripening (after 7 and 21 days). Whey was also analysed by the potentiometric electronic tongue. Results obtained by the electronic nose and tongue were found to be complementary, with the electronic nose being more sensitive to differences in the milk and the electronic tongue b...

Identification of key genes and pathways associated with osteogenic differentiation of adipose stem cells.

Adipose stem cells (ASCs) are considered a great alternative source of mesenchymal stem cells (MSCs) and have shown great promise on tissue engineering and regenerative medicine applications, including bone repair. However, the underlying mechanisms regulating the osteogenic differentiation of ASCs remain poorly known. Gene expression profiles of GSE63754 and GSE37329 were downloaded from gene expression omnibus database. R software and Bioconductor packages were used to compare and identify the differentia...
