The incidence rate in men is about four times more than that in women, and the age range of patients diagnosed is 50-54 years in both males and females, with a sharper increase in males aged 60-64 years. 1 BC is the seventh most frequent cancer type worldwide. Approximately 30% of bladder tumors are anticipated to emerge from occupational exposure to carcinogens, including benzidine and 2-naphthylamine. Cigarette smoke also contains such carcinogens and is a risk factor for BC. Several jobs types, such as rubber workers, motor mechanics, leather (including shoe) workers, machine setters, bus drivers, blacksmiths, hairdressers (due to hair dye exposure), and mechanics are at greater risk of BC. [2][3][4] The malignancy of BC in most humans appears to be multifactorial in origin and develops in multiple stages. 5,6 The natural environment may consist of review article

Objective: Inflammation plays a significant role in the development of ischemic stroke. CXC chemokines play pleiotropic roles in prolonged leukocyte locomotion, astrocyte migration/activation, and neural attachment/sprouting in response to focal stroke. In this study, we aimed to explore the changes in serum levels of three chemokines, C-X-C motif chemokine ligand 1 (CXCL1), C-X-C motif chemokine ligand 9 (CXCL9), and C-X-C motif chemokine ligand 10 (CXCL10), in ischemic stroke patients at the time of admission and before discharge from the hospital ward. Materials and Methods:In this study, we recruited 43 unrelated ischemic stroke patients using an easy convenience method or accidental sampling which is a type of non-probability sampling that involves the sample being drawn from that part of the population that is close to hand. We also enrolled 50 genetically unrelated healthy controls showing no history of neurologic, cardiovascular, or inflammatory diseases. Serum levels of the considered chemokines were measured by enzyme-linked immunosorbent assay (ELISA) in patients and healthy controls.Results: No significant difference was observed in ischemic stroke patients following hospitalization and prior discharging from the hospital; however, there was a significant difference in serum levels of CXCL9 and CXCL10 between patients and healthy controls. We also found that the level of the chemokine was not related to gender or medical therapy. It appears that CXCL9 and CXCL10 are more predisposing factors and play a direct role in stroke considering that they were higher in patients than in healthy controls. Conclusion:We believe that this study might be used as a basis for further studies on more effective medication regimens to prevent the onset and subsequent complications of stroke. However, these mediators are useful diagnostic and prognostic tools rather than therapeutic tools.Keywords: Chemokine, ischemia, stroke ÖZ Amaç: Enflamasyon iskemik inme gelişiminde önemli bir rol oynar. CXC kemokinlerinin fokal inmeye yanıt olarak gelişen nöral bağlanma/filizlenme, astrosit migrasyon/aktivasyon ve uzamış lökosit lokomosyonunda pleiotropic etkileri vardır. Bu çalışmada iskemik inmeli hastalarda, C-X-C motif kemokin ligand 10 (CXCL10), C-X-C motif kemokin ligand 1 (CXCL1) ve C-X-C motif kemokin ligand 9'u (CXCL9) içeren üç kemokinin serum düzeyindeki değişikliklerinin hastaneye kabul ve taburculuk sırasında araştırılması amaçlanmıştır.Gereç ve Yöntem: Bu çalışmada, kolay uygunluk yöntemi kullanılarak birbiriyle ilişkisi olmayan 43 iskemik inmeli hasta incelendi. Ayrıca herhangi bir nörolojik, kardiyovasküler veya inflamatuvar hastalık öyküsü olmayan, genetik olarak birbiriyle bağlantısız 50 sağlıklı denek de çalışmaya dahil edildi. Hastalarda ve sağlıklı kontrollerde kemokinlerin serum düzeyleri enzime bağlı bağışıklık deneyi (ALISA) ile ölçüldü.Bulgular: Mevcut çalışmada, iskemik inme geçirdiği için hastaneye yatırılan ve taburcu edilen hastalarda anlamlı bir farklılık izlenmedi. Ancak, hastalar ve sağlıklı...

This study investigated the potential of Persian shallot extract as an anticancer agent in HepG2 tumor cell line, an in vitro human hepatoma cancer model system. The inhibitory effect of Persian shallot on the growth of HepG2 cells was measured by MTT assay. To explore the underlying mechanism of cell growth inhibition of Persian shallot, the activity of Persian shallot in inducing apoptosis was investigated through the detection of annexin V signal by flow cytometry and expression of some apoptosis related genes such p21, p53, puma, caspase-8 family-Bcl-2 proteins like bid, bim, bcl-2 and bax were measured by real-time PCR in HepG2 cells. Persian shallot extract inhibited the growth of HepG2 cells in a dose-dependent manner. The IC value (inhibiting cell growth by 50%) was 149 μg/ml. The results of real-time PCR revealed a significant up-regulation of bid, bim, caspase-8, puma, p53, p21 and bax genes and a significant downregulation of bcl-2 gene in HepG2 cells treated with Persian shallot extract significantly. Therefore, this is the first report on an increased expression of bid, bim, caspase-8, puma, p53, p21 and bax genes and down regulation of bcl-2 gene indicating that the Persian shallot extract possibly induced the process of cell death through the intrinsic and extrinsic apoptosis pathways and triggers the programmed cell death in HepG2 tumor cell lines by modulating the expression of pro-/anti-apoptotic genes. Furthermore, we showed that Persian shallot extract increased annexin V signal and expression, resulting in apoptotic cell death of HepG2 cells after 24 h treatment. Therefore, according to the results of this study, the Persian shallot extract could be considered as a potential candidate for production of drug for the prevention or treatment of human hepatoma.
