Cell lines derived from human squamous cell (EPCL), large cell (LCLC), and small cell lung cancer (SCLC) lines were investigated for the expression of cathepsin B (Cat B) and cysteine proteinase inhibitors (CPIs). The EPLC and LCLC lines expressed 5- to 50-fold more Cat B activity and contained more mature Cat B of M(r) 27-29 kDa (> 2.5 microg/mg total protein) than the SCLC lines (< 1.0 microg/mg
In this paper we describe the flight characteristics of a swift (Apus apus) in cruising flight at three different flight speeds (8.0, 8.4 and 9.2 m s(-1)) in a low turbulence wind tunnel. The wingbeat kinematics were recorded by high-speed filming and the wake of the bird was visualized by digital particle image velocimetry (DPIV). Certain flight characteristics of the swift differ from those of p
Three adult de novo acute myeloid leukemias (AML M1, M2, and M4) with an isochromosome 7p are presented. No additional abnormalities were deterred by G-band and multicolor, using combined binary ratio labeling, fluorescence in situ hybridization (FISH) analyses, indicating that the i(7p) was the sole. i.e., the primary, chromosomal aberration. Although the patients were elderly-68, 72, and 78 year
The aim of the present study was to explore whether it was possible to differentiate the clinical course and the otomicroscopic appearance of acute otitis media (AOM) caused by common otitis pathogens in an animal model. Systemic interleukin (IL)-6 levels as early markers for bacterial AOM were also studied. Four groups of rats were inoculated with either Streptococcus pneumoniae, Streptococcus py
We examined the proximal conformation of three commonly used self-expanding stents when the stents were deployed adjacent to one another in a tubular model, simulating a "kissing" stent technique. The stent pairs were evaluated by computed tomogrphy to determine the cross-sectional area excluded by the stents within the model. The mean areas associated with each stent pair were compared and signif
Cell surface heparan sulfate proteoglycans facilitate uptake of growth-promoting polyamines (Belting, M., Persson, S., and Fransson, L.-A. (1999) Biochem. J. 338, 317-323; Belting, M., Borsig, L., Fuster, M. M., Brown, J. R., Persson, L., Fransson, L.-A., and Esko, J. D. (2001) Proc. Natl. Acad. Sci. U. S. A., in press). Here, we have analyzed the effect of polyamine deprivation on the structure a
Genome-wide association studies have identified a number of signals for both Type 2 Diabetes and related quantitative traits. For the majority of loci, the transition from association signal to mutational mechanism has been difficult to establish. Glucokinase (GCK) regulates glucose storage and disposal in the liver where its activity is regulated by glucokinase regulatory protein (GKRP; gene name
Purpose: To compare, absolute cerebral blood flow (CBF) estimates obtained by dynamic susceptibility contrast MRI (DSC-MRI) and Xe-133 SPECT. Materials and Methods: CBF was measured in 20 healthy volunteers using DSC-MRI at 3T and Xe-133 SPECT. DSC- MRI was accomplished by gradient-echo EPI and CBF was calculated using a time-shift-insenisitive deconvolution algorithm and regional arterial input f
In healthy subjects, acute inhalation of swine dust causes an influx of inflammatory cells into the airways and increased bronchial responsiveness. The exposure may also cause fever and generalized symptoms. It seems likely that proinflammatory cytokines are involved in the response to inhaled swine dust. Nasal and bronchoalveolar lavage (BAL) were performed before, and 7 and 24 h after the start
Direct aeroacoustic computations require nonreflective boundary conditions that allow disturbances to leave the domain freely without anomalous reflections. In the present paper we analyze a series of nonreflective boundary conditions already published in the literature and propose an improved outflow nonreflective boundary condition with reflection characteristic that is reduced greatly. For the
A retrospective study of 18 patients with femoral hernia assessed by herniography is presented. Although a palpable lump was present in 11 patients (61%), the diagnosis of a femoral hernia was not made before herniography. Surgical exploration was performed in 12 patients and a femoral hernia was found and repaired with beneficial outcome in 9 of them. In conclusion: herniography is of value for t
The aim of the study was to determine whether an impairment of the haemostasis could be observed experimentally when thromboprophylactic substances, which act differently on the haemostatic mechanism, were given single or in combination in prophylactic doses. In 36 rabbits we measured the primary haemostatic plug formation time (PHT), rebleedings and total haemostatic plug formation time (THT) aft
The fluid dynamics of many swimming and flying animals involves the generation and shedding of vortices into the wake. Here we studied the dynamics of similar vortices shed by a simple two-dimensional flapping foil in a soap-film tunnel. The flapping foil models an animal wing, fin or tail in forward locomotion. The vortical flow induced by the foil is correlated to (the resulting) thickness varia
The aim of the present Study was to make a 16-year follow-up of children of psychosocial risk mothers as concerns emotional/behavioural problems, self-esteem, life events, and academic grades. Forty-three teenagers (index group) and 61 reference teenagers were personally interviewed and asked to answer the Youth Self-report (YSR), the Self-image questionnaire I Think I Am, and a Life Event questio
BACKGROUND: Activated mast cells can produce and release a number of inflammatory mediators involved in the pathophysiology of acute conditions. The aim of the present study was to evaluate the role of activated tissue mast cells in the pathogenesis of multiple organ dysfunction syndrome following acute pancreatitis (AP). METHODS: AP was induced by the intraductal infusion of 5 per cent sodium tau
BACKGROUND. With a substantial rise in the incidence of skin cancer, skin surgery has become an increasingly large part of dermatology. Skin surgery is best performed by dermatologists. This demands effective training in dermatologic surgery, including flap surgery. OBJECTIVE. To find a modern alternative to traditional training on pig's feet skin in teaching flap surgery to residents in dermatolo
The relationship between monthly sea-surface temperature (SST) in the tropical Pacific and the Indian Ocean and monthly precipitation over the Vietnamese central highlands (VCH) has been investigated by means of singular value decomposition. The seasonal variation of SST plays a critical role in the onset of the monsoon season and convective rain band movement in the inter-tropical convergence zon
