Among the factors that control the survival of microorganisms on human stratum corneum are skin lipids, including sphingosines. Because the antibacterial spectrum of sphinganine resembles that of cell wall antibiotics, electron microscopy of sphinganine-treated and untreated S. aureus was performed; the lipid induced multiple lesions of cell wall, membrane(More)
Neurogenic stunned myocardium is widely reported in the adult literature and is typically associated with subarachnoid hemorrhage. We present a case of neurogenic stunned myocardium and transient severe tricuspid regurgitation in a 7-month-old infant following nonaccidental head trauma.
Joint injury and osteoarthritis affect millions of people worldwide, but attempts to generate articular cartilage using adult stem/progenitor cells have been unsuccessful. We hypothesized that recapitulation of the human developmental chondrogenic program using pluripotent stem cells (PSCs) may represent a superior approach for cartilage restoration. Using(More)
Hemodynamic studies were carried out before and during 8 weeks of treatment with hydrochlorothiazide 50 mg. twice daily in 11 hypertensive patients. Forty-eight hours after beginning treatment there was a significant reduction in blood pressure, cardiac output, plasma volume, and extracellular fluid volume (thiocyanate space) while total peripheral(More)
Cartilage injury represents one of the most significant clinical conditions. Implantation of expanded autologous chondrocytes from noninjured compartments of the joint is a typical strategy for repairing cartilage. However, two-dimensional culture causes dedifferentiation of chondrocytes, making them functionally inferior for cartilage repair. We(More)
Giant left atrium associated with mitral valve disease has been implicated in the morbidity following mitral valve repair or replacement. Various methods including left atrial plication have been described to reduce the size of left atrium. Herein we describe our technique of left atrial reduction in a 5-year-old girl with severe mitral regurgitation and(More)
BACKGROUND About one third of lumbar synovial cysts are associated with degenerative spondylolisthesis. Segmental instability is thought to contribute to the pathogenesis and recurrence of synovial cysts and lumbar fusion has been advocated as a treatment of choice in the presence of spondylolisthesis. In patients with spondylolisthesis, minimally invasive(More)
Obesity and diabetes are strongly associated with metabolic and cardiovascular disorders including dyslipidemia, coronary artery disease, hypertension, and heart failure. Adipose tissue is identified as a complex endocrine organ, which by exerting a wide array of regulatory functions at the cellular, tissue and systemic levels can have profound effects on(More)
