The aim of the present study was to investigate the anti-inflammatory effects of 14,15-epoxyeicosatrienoic acid (EET) on reactivity and Ca(2+) sensitivity in TNF-alpha-stimulated human bronchi. Tension measurements performed on either control, TNF-alpha-, or TNF-alpha + EET-pretreated bronchi revealed that 100 nM 14,15-EET pretreatments significantly(More)
Airway smooth muscle (ASM) metabolizes arachidonic acid (AA) through various enzymatic pathways, including cytochrome P-450 (CYP-450) omega-hydroxylase, which leads to the production of 20-hydroxyeicosatetraenoic acid (20-HETE). The goal of this study was to delineate the mode of action of 20-HETE in human ASM cells. Isometric tension measurements(More)
OBJECTIVE To verify the frequency of discrepancies between clinical diagnoses and autopsy findings in patients from a pediatric intensive care unit and to look for predictive factors of the discrepancies. DESIGN Prospective evaluation performed between September 1996 and December 1998. SETTING Eight-bed pediatric intensive care unit of a university(More)
OBJECTIVE The purposes of this article are to summarize the relevant literature on aerogenous metastasis, explain the putative pathogenetic mechanism of aerogenous spread, present the characteristic imaging and pathologic features, and review the importance of aerogenous spread to staging and clinical management. CONCLUSION Cumulative evidence suggests(More)
The aim of the present study was to provide a mechanistic insight into how 14,15-epoxyeicosatrienoic acid (EET) relaxes organ-cultured human bronchi. Tension measurements, performed on either fresh or 3-d-cultured bronchi, revealed that the contractile responses to 1 microM methacholine and 10 microM arachidonic acid were largely relaxed by the eicosanoid(More)
We describe the clinical and pathologic findings of a 68-year-old smoker with previous asbestos exposure who presented with spontaneous hydropneumothorax and was diagnosed with synchronous undifferentiated lung carcinoma and incidental malignant pleural mesothelioma. The synchronous occurrence of these two neoplasms is an extremely rare event with fewer(More)
BACKGROUND Chronic rhinosinusitis (CRS) is an inflammatory disease in which bacteria are commonly implicated often in the form of a biofilm. Manuka honey has been shown in vitro to be an effective treatment against two common CRS pathogens both in the planktonic and in the biofilm forms. The purpose of this study was to determine if the application of(More)

Despite recent advances in treatment modalities, the survival rate of patients with lung cancer has not significantly improved. Therefore, new avenues are being explored in the era of evolving personalized patient management by early detection. Cytology is now the mainstay to address the diagnostic needs of pulmonary malignancies. Cytology specimens deliver(More)
Internet of Things (IoT) supports a connection between objects and humans, enabling the ubiquitous computing in our daily lives. Future research directions in IoT infrastructure should consider real-time communication and scalability to provide a better experience to the users. We justify this sentence by developing an IoT micro-benchmark, which was(More)
