There are many well-defined risk factors for fatal asthma exacerbation; however, few data exist about the link between the severity of asthma and severity of exacerbation. The aim of this study was to determine if there is any patient and disease-related factor that predicts the severity of asthma exacerbation. The retrospective data of asthmatic patients followed up in our clinic were analyzed. Asthmatic patients who had at least one exacerbation were included. Patient and disease characteristics, comorbidities, and compliance were evaluated. We analyzed 335 asthma exacerbations of 189 asthmatic patients. Eighteen patients had intermittent asthma, 115 patients had mild persistent asthma, 45 patients had moderate persistent asthma, and 11 patients had severe persistent asthma. Of the 189 asthmatic patients 8.1% of the exacerbations were mild, 52.5% were moderate, and 39.4% were severe. There was a significant correlation between the severity of asthma and severity of exacerbation (r = 0.32; p < 0.001). When elderly (60 years old) and younger (< 60 years old) asthmatic patients were compared, elderly asthmatic patients had severe asthma exacerbation significantly at a higher rate than younger asthmatic patients (severe asthma exacerbation rates are 67.3 and 33.9% in elderly patients and younger asthmatic patients, respectively; p < 0.001). A significant correlation was found between the severity of exacerbation and age (r = 0.25; p < 0.001). Among the other patient and disease-related factors, asthma severity and older age were the only significant factors that contributed to the severity of exacerbation. These data show that older age as a patient-related factor and worse asthma severity as a disease-related factor could contribute to exacerbation severity in asthmatic patients.

MTA-1 expression is associated with metastasis and epithelial to mesenchymal transition in colorectal cancer cells Cagatay, Seda Tuncay; Cimen, Ismail; SAVAŞ, BERNA; Banerjee, Sreeparna (Springer Science and Business Media LLC, 2013-04-01) Although metastasis associated protein 1 (MTA1) has been widely linked to tumor metastasis, the relevant mechanisms remain to be elucidated, especially in colorectal cancer (CRC). Here, we have investigated the link between MTA1, metastasis and epithelial-mesenchymal transition (EMT) in CRC. Eighteen normal colon tissues and 91 resected tumor samples were analyzed for MTA1 expression by immunohistochemistry (IHC). IHC indicated low or no nuclear MTA1 expression in the normal tissues and significantly higher...
Association analysis of Glutathione S-transferase omega-1 and omega-2 genetic polymorphisms and ischemic stroke risk in a Turkish population Bilgin, Esra; Can Demirdöğen, Birsen; Ozcelik, Aysun Turkanoglu; Demirkaya, Seref; Adalı, Orhan (Informa UK Limited, 2019-01-01) Objectives: Oxidative stress is a known risk factor for the pathogenesis of atherosclerosis, the main cause of ischemic stroke. Glutathione S-transferase (GST) omega-1 and omega-2, members of phase II enzymes, play a role in the antioxidant system. The single nucleotide polymorphisms (SNPs), C419A and A424G in GST omega genes can cause a decrease in enzyme activity. The aim of this study was to investigate the possible association between these polymorphisms and ischemic stroke risk in a Turkish population.
Etiology of senile osteoporosis - A hypothesis Atik, O. Sahap; Uslu, M. Murad; Eksioglu, Fatih; Satana, Tolgay (Ovid Technologies (Wolters Kluwer Health), 2006-02-01) Osteoporosis is a major health problem characterized by compromised bone strength predisposing patients to an increased risk of fracture. It may cause morbidity and mortality in elderly men and women. The etiologic factors that lead to senile osteoporosis still are unclear.
Inhibition of the TIRAP-c-Jun interaction as a therapeutic strategy for AP1-mediated inflammatory responses Srivastava, Mansi; Saqib, Uzma; Banerjee, Sreeparna; Wary, Kishore; Kizil, Burak; Muthu, Kannan; Baig, Mirza S. (Elsevier BV, 2019-06-01) Bacterial endotoxin-induced sepsis causes 30-40% of the deaths in the intensive care unit (ICU) globally, for which there is no pharmacotherapy. Lipopolysaccharide (LPS), a bacterial endotoxin, stimulates the Toll-like receptor (TLR)-4 signalling pathways to upregulate the expression of various inflammatory mediators. Here, we show that the TIRAP and c-Jun protein signalling complex forms in macrophages in response to LPS stimulation, which increases the AP1 transcriptional activity, thereby amplifying the ...
Identification of biomarkers associated with partial epithelial to mesenchymal transition in the secretome of slug over-expressing hepatocellular carcinoma cells Karaosmanoglu, Oguzhan; Banerjee, Sreeparna; SİVAS, HÜLYA (Springer Science and Business Media LLC, 2018-08-01) Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related deaths worldwide. Complete epithelial to mesenchymal transition (EMT) has long been considered as a crucial step for metastasis initiation. It has, however, become apparent that many carcinoma cells can metastasize without complete loss of epithelial traits or with incomplete gain of mesenchymal traits, i.e., partial EMT. Here, we aimed to determine the similarities and differences between complete and partial EMT through over-expr...
