The spectrum of vascular tumors ranges from hemangioma (HEM), to epithelioid hemangioendothelioma (EHE) and to angiosarcoma (AS). To the best of our knowledge, the usefulness of F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) for vascular tumors has never been comprehensively studied. The present study investigated the usefulness of FDG-PET for pathologically diagnosed vascular t...

Acute lung injury (ALI) is identified with the targeting/sequestration of polymorphonuclear leukocytes (PMN) to the lung. Instrumental to PMN targeting are chemokines [e.g., macrophage inflammatory protein-2 (MIP-2), keratinocyte-derived chemokine (KC), etc.] produced by macrophage, PMN, and other resident pulmonary cells. However, the relative contribution of resident pulmonary macrophages as ...

Gereç ve yöntemler: Çalışmada 21 sol distal femur kırığı modeli kullanıldı. Kemikler 3 eşit gruba ayrıldı. Grup 1 örnekleri distal femur anatomik kilitli plak ile yandan tespit edildi. Grup 2 örnekleri distal femur retrograd İM çivi ile tespit edildi. Grup 3 örnekleri hem distal femur anatomik kilitli plak hem distal femur retrograd İM çivi ile tespit edildi. Mekanik testlerde aksiyel yüklenme ...

Bulgular: Hastalar›n serum ve CSF örneklerinde, GPX aktiviteleri ve GSH düzeyleri ve TAC kontrol grubuna göre anlaml› flekilde daha düflüktü. Kontrol grubu ile karfl›laflt›r›ld›¤›nda hasta grubu serum örneklerinde azalm›fl SOD aktivitesi ve CSF örneklerinde ise artm›fl SOD aktivitesi bulundu. Kontrol grubu ile karfl›laflt›r›ld›¤›nda stroklu hastalarda hem serum hem de CSF MDA konsantrasyonu dah...

Within the confines of a Healthcare Enterprise Memory (HEM), most traditional medical systems do not sufficiently provide the necessary assistance to healthcare practitioners in the handling of critical situations. Furthermore, localized knowledge repositories are often lacking the required knowledge for problem solving. Therefore, in this paper, we present an agentbased knowledge broker called...

We demonstrate that the expression of hem genes in Rhodobacter capsulatus is transcriptionally repressed in response to the exogenous addition of heme. A high-copy suppressor screen for regulators of hem gene expression resulted in the identification of an LysR-type transcriptional regulator, called HbrL, that regulates hem promoters in response to the availability of heme. HbrL is shown to act...

The Fisher Hem-Alyzer is a multitest sequential discrete analyser with automatic printout of digitized results on paper tape. The instrument is well designed, soundly constructed, and reliable in routine use. Cross contamination from the sampler probe or between the cuvettes is minimal. Accuracy and precision are both highly satisfactory. Although the standard rate of throughput is 32 specimens...

Background Hereditary hemochromatosis, thalassemia and myelodysplastic sindromes represent iron toxicity models with evidence of iron-related heart failure. Non-TransferrinBound Iron (NTBI), plays a key role in the pathogenesis of cardiac toxicity leading to the production of reactive oxygen species which increase lipid peroxidation (MDA). In acute myocardial infarction (MI) microvascular obstr...

Bu çalışma, Beckçi ‟Risk Toplumu” konseptinin, genelde ekolojik kriz özelde ise iklim mülteciliği meselelerine karşı önemli imkânlar barındıran bir teorik arka plan sağladığını gösterme amacıyla yazılmıştır. Çalışma kapsamında bu temel amaç doğrultusunda iki ana meseleye odaklanılmıştır. Bunlardan ilki olarak, kuramsal çerçevede merkezi yeri olduğunu düşündüğümüz risklerin risk toplumu kategori...
