Ultrasound is a reliable tool to diagnose patent ductus arteriosus in premature infants but no reliable noninvasive method exists to quantify ductal flow. The aim of this study was to quantify the size of the shunt via persistent ductus arteriosus from pixel counts in color Doppler flow images. A cotton band was placed around the ductus arteriosus of newborn lambs to adjust the magnitude of flow.
The stem cell factor receptor/c-Kit plays an important physiological role in hematopoesis, melanogenesis and gametogenesis. It has also been implicated in numerous human malignancies. Signal transduction pathways shown to be of importance for c-Kit mediated transformation include the PI3-kinase/Akt pathway. We have previously shown that two alternative splice forms of c-Kit, denoted GNNK- and GNNK
OBJECTIVE: To create a library enriched in cDNAs from preeclamptic placentas to print onto microarrays for placental profiling of preeclampsia (PE) and high risk pregnancies. DESIGN: Prospective study. SETTING: University women's clinic and academic research laboratory. PATIENT(S): Ten patients with PE, 5 with PE and bilateral notching, 5 with bilateral notching without PE, and 15 normotensive pat
We demonstrate an improved technique to precisely localize inhomogeneities in turbid media by means of reconstructing diffuse photon-density wave interference from time-resolved transmittance measurements applying the Fourier transform. This interference can also be obtained in the reverse mode, that is using a single source and combining the signals detected at several locations. This increases t
Shows that one-particle calculations of X-ray spectra with and without the core hole can give drastically different results, indicating a breakdown of one-particle theory. Only emission spectra obtained in the absence of the core hole consistently show a close resemblance to experiment. The authors show, that this fact can be explained by the many-body theory of Nozieres and DeDominicis (1969). Th
Abstract in Uncoded languages Namen prispevka:Namen prispevka je analizirati ponovno podane izkušnje 27-ih preživelih vojne v Bosni in Hercegovini v 90-ih letih prejšnjega stoletja. V pripovedih smo pregledali verbalne znake sprave in pomiritve ter analizirali opisane izraze za spravo. Metode: Gradivo za raziskavo je bilo zbrano s kvalitativnimi intervjuji 27-ih posameznikov, ki so preživeli vojnoPurpose: The aim of this article was to analyze the retold experiences of 27 survivors from the 1990s war in Bosnia and Herzegovina. I have examined verbal markers of reconciliation and implacability and analyzed the described terms for reconciliation that are being actualized in the narratives. Design: The material for the study was gathered through qualitative interviews with 27 individuals who
Patients with hip and knee osteoarthritis (OA) have high bone mineral density (BMD) and high BMI. If the same accounts for patients with foot or ankle OA is unknown.
Measurements have been performed at eight laboratories on Raman-shifted radiation from frequency-quadrupled Nd:YAG and KrF lasers. Each of these sources is a possible candidate for making differential-absorption lidar measurements of ozone in the free troposphere. The spectral purity, efficiency and divergence of the different sources are compared and explained using a simplified model of the Rama
BACKGROUND: Abnormal cerebrospinal fluid (CSF) biomarker levels predict development of Alzheimer disease with good accuracy and are thought to precede cognitive deterioration. OBJECTIVE: To investigate whether changes in CSF biomarker levels over time in healthy older adults are associated with a concurrent decline in cognitive performance. DESIGN: Retrospective analysis of longitudinal CSF biomar
Intratumoral heterogeneity is an inherent feature of most human cancers and has profound implications for cancer therapy. As a result, there is an emergent need to explore previously unmapped mechanisms regulating distinct subpopulations of tumor cells and to understand their contribution to tumor progression and treatment response. Aberrant platelet-derived growth factor receptor beta (PDGFRβ) si
Laser-induced fluorescence was used to characterize the localization of intravenously administered benzoporphyrin derivative-monoacid (BPD-MA) 3 h postinjection in different rat tissue types, including an induced experimental malignant tumor. A comparison of the fluorescence properties and the demarcation potential between the newer sensitizer BPD-MA and four other substances, hematoporphyrin (HP)
Jon Elster worries about the explanatory power of the social sciences. His main concern is that they have so few well-established laws. Elster (2007) develops an interesting substitute: a special kind of mechanism designed to fill the explanatory gap between laws and mere description. However, his mechanisms suffer from a characteristic problem which I will explore in this article. As our causal k
The purpose of this study was to measure changes in intensity and pitch matches to better assess disease activity in fluctuating hearing loss. Long-term suprathreshold audiometry was carried out at home on a subject with a unilateral fluctuating low-frequency hearing loss during a period when the subject demonstrated no symptoms and a period when the subject reported hearing loss, aural pressure,
Introduction: Endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) is an emerging minimally invasive option for pathologic examination of intrathoracic lymphadenopathy as well as for staging lung cancer. Objectives: To evaluate the diagnostic yield and possible learning curve effects on diagnostic performance using EBUS-TBNA in mediastinal lymphadenopathy. Methods: A retrospect
Overweight and obesity is associated with an increased risk of postmenopausal breast cancer. However, less is known about the impact of anthropometric factors on tumor pathology and biology. A Swedish population-based prospective cohort study of 9,685 postmenopausal women not using hormonal replacement therapy (HRT) were followed for an average of 10.3 years during which 305 incident breast cancer
Structural changes to the lung are known to be associated with chronic asthma. In addition to the well-described alterations to the airway wall, asthma is also associated with vascular modifications, although this aspect of remodeling is poorly understood. We therefore sought to evaluate the character and kinetics of vascular remodeling in response to chronic aeroallergen exposure. However, since
An increased risk of malignant melanoma has been observed in men with prostate cancer. To assess potential shared risk factors and confounding factors, we analysed risk of melanoma in men with prostate cancer including information on tumor characteristics and demographics including socioeconomic status. In The Prostate Cancer data Base Sweden, risk of melanoma was assessed in a cohort of men with
The study aims were to estimate the radiation dose in patients examined with low dose spine CT and to compare it with that received by patients undergoing standard CT for trauma of the same region, as well as to evaluate the impact of dose reduction on image quality. Radiation doses in 113 consecutive low dose spine CTs were compared with those in 127 CTs for trauma. The inter- and intraobserver a
BACKGROUND: Treatment of diabetic foot ulcers includes a number of different regimes such as glycaemic control, re-vascularization, surgical, local wound treatment, offloading and other non-surgical treatments. Although considered the standard of care, the scientific evidence behind the various debridements used is scarce. This presentation will focus on debridement and V.A.C. Therapy, two treatme
