BACKGROUND: The purpose of this study was to evaluate the ultrasound technique for measuring subcutaneous adipose tissue in infants. METHODS: Twenty infants were investigated at 3, 6, and 12 months of age. All measurements were made by the same investigator in triplicate on the left side of the body at the triceps and subscapular anatomic landmarks and at the abdomen and thigh. An ultrasound syste
Mutations in the PTEN gene are associated with a broad spectrum of disorders, including Cowden syndrome (CS), Bannayan-Riley-Ruvalcaba syndrome, Proteus syndrome, and Lhermitte-Duclos disease. In addition, PTEN mutations have been described in a few patients with autism spectrum disorders (ASDs) and macrocephaly. In this study, we screened the PTEN gene for mutations and deletions in 88 patients w
BACKGROUND: Anesthetic agents alter pharyngeal function with risk of impaired airway protection and aspiration. This study was performed to evaluate pharyngeal function during subhypnotic concentrations of propofol, isoflurane, and sevoflurane and to compare the drugs for possible differences in this respect. METHODS: Forty-five healthy volunteers were randomized to receive propofol, isoflurane, o
In vitro expanded neural stem/progenitor cells can undergo region-specific differentiation after transplantation to the developing or adult brain, and display morphologies and markers characteristic of mature neurons. Here we have used patch-clamp techniques to explore whether grafted stem cells also can develop physiological properties of mature neurons and become functionally integrated within h
Microsomal glutathione (GSH) transferase 1 (MGST1) is a trimeric, integral membrane protein involved in cellular response to chemical or oxidative stress. The cytosolic domain of MGST1 harbors the GSH binding site and a cysteine residue (C49) that acts as a sensor of oxidative and chemical stress. Spatially resolved changes in the kinetics of backbone amide H/D exchange reveal that the binding of
An analytical strategy to determine metals in environmental samples contaminated with both organophosphate pesticides and metals is presented. In the first step, parathion and arsenate were determined separately. Inhibition of the enzyme butyrylcholinesterase was quantified employing an enzyme thermistor and also with a CCD camera. Subsequently, parathion mixed with arsenate was measured. A molecu
Galanin is probably involved in nociceptive sensory processing in spinal cord. We investigated whether a common injury, peripheral nerve compression, induced up-regulation of galanin (immunocytochemistry) in sensory neurons in rats 6 or 14 days post-injury and compared the response with other nerve injuries. Sciatic nerve compression increased the number of galanin positive sensory neurons as comp
Background and Purpose: The 'capsular warning syndrome' (CWS) of recurrent stereotyped episodes of motor or sensory dysfunction is clinically well recognized, and is associated with a high risk of imminent lacunar infarction with permanent deficits resembling those of CWS. However, the pathophysiology of CWS has not been well characterized. We report a clinicoanatomic correlation with MR imaging s
We present a method providing synchronized measurements using the two techniques: quartz crystal microbalance with dissipation (QCM-D) monitoring and localized surface plasmon resonance (LSPR). This was achieved by letting a thin gold film perforated with short-ranged ordered plasmon-active nanoholes act as one of the electrodes of a QCM-D crystal. This enabled transmission-mode optical spectrosco
Multiple organ dysfunction syndrome (MODS) is mediated by complex mechanisms in which interactions between activated leukocytes and endothelial cells play a central role. ICAM-1 (intercellular adhesion molecule-1) mediates firm adhesion and transendothelial migration of activated leukocytes from postcapillary venules into the tissue. The present study evaluated the ICAM-1 expression in various org
Associations between adolescent smoking habits and exercise, particularly participation in sports and lung function were studied. All students aged 13-19 yrs in Nord-Trondelag County, Norway, 1995-1997, were invited to join a cross-sectional study. Information on smoking habits and exercise was obtained by self-administered questionnaire. Spirometry was performed in accordance with American Thorac
The most widely used model for rheumatoid arthritis is the collagen-induced arthritis (CIA) in mice. This model has gained acceptance since it is reproducible, well defined and has proven useful for development of new therapies for rheumatoid arthritis, as exemplified by the most recent advancement using TNFalpha neutralization treatment. The collagen-induced arthritis model, however, represents o
A microfluidic approach for raw milk sample preconditioning prior to protein and lipid content analysis has been developed. The system utilizes microchip acoustophoresis and is a further extension of our previously reported multiple node ultrasonic standing wave focusing platform ( Grenvall , C. , Augustsson , P. , Matsuoka , H. and Laurell , T. Proc. Micro Total Anal. Syst. 2008 , 1, 161-163 ). T
Background: Approximately 25% of severe hemophilia A (HA) patients develop antibodies to factor VIII protein. Patients: In the present case-controlled cohort study, 260 severely affected, mutation-type-matched HA patients were studied for association of human leukocyte antigen (HLA) class II molecules and polymorphisms in the genes encoding interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-
Turnover rates of arbuscular mycorrhizal (AM) fungi may influence storage of soil organic carbon (SOC). We examined the longevity of AM hyphae in monoxenic cultures; and we also used C-13 incorporation into signature fatty acids to study C dynamics in a mycorrhizal symbiosis involving Glomus intraradices and Plantago lanceolata. C-13 enrichment of signature fatty acids showed rapid transfer of pla
Objective A patient presented with heavy-chain deposition disease (HCDD), exhibiting severe erosive polyarthropathy caused by synovial deposits of abnormal monoclonal, heavily deleted free 3 heavy chains lacking the VH and CH1 domains. The absence of VH was surprising, since it is considered important for pathogenic tissue deposition. This study was undertaken to analyze the genetic structure of
