    Aim: The aim of this study was to analyze studies in Turkey about self-breast examination and produce conclusive, reliable and detailed basis for future studies. Methods: Studies performed between 2000 and 2009 (until the end of September) were retrieved from databases using breast cancer, breast examination, breast cancer screening and risk factors as key words. Fifty-nine studies were identified and 18 of them (15 journal articles and three theses) were used for the meta-analysis. Results: Married women and women with a family history of breast cancer were found to perform self-breast examination more frequently than single women and women without a family history of breast cancer, respectively (OR=1.02 %CI 0.82-1.63; OR=1.16 %CI 0.82-1.63). According to the health belief model scales, women performing self-breast examination were determined to have 1.7 times higher susceptibility (OR=1.70), 1.34 times higher seriousness perception (OR=1.34), 3.32 times higher health motivation (OR=3.32), 5.21 times more self-efficacy/confidence (OR=5.21) and 2.56 times higher self-breast examination benefit perception (OR=2.56). Conclusion: Nursing care models caused an increase in self-breast examination by women, and thus, it may be useful to organize and evaluate such health-related programs and consider women health perceptions

    Background: To compare the multidetector computed tomography (MDCT) arthrography (CTa) and magnetic resonance (MR) arthrography (MRa) findings with surgical findings in patients with femoroacetabular impingement (FAI) and to evaluate the diagnostic performance of these methods. Material/Methods: Labral pathology and articular cartilage were prospectively evaluated with MRa and CTa in 14 hips of 14 patients. The findings were evaluated by two musculoskeletal radiologists with 10 and 20 years of experience, respectively. Sensitivity, specificity, accuracy, and positive predictive value were determined using surgical findings as the standard of reference. Results: While the disagreement between observers was recorded in two cases of labral tearing with MRa, there was a complete consensus with CTa. Disagreement between observers was found in four cases of femoral cartilage loss with both MRa and CTa. Disagreement was also recorded in only one case of acetabular cartilage loss with both methods. The percent sensitivity, specificity, and accuracy for correctly assessing the labral tearing were as follows for MRa/CTa, respectively: 100/100, 50/100, 86/100 (p0.05) and for femoral cartilage assessment were 100/75, 90/70, 86/71 (p>0.05). Inter-observer reliability value showed excellent agreement for labral tearing with CTa (k=1.0). Inter-observer agreement was substantial to excellent with regard to acetabular cartilage assessment with MRa and CTa (k=0.76 for MRa and k=0.86 for CTa) Conclusions: Inter-observer reliability with CTa is excellent for labral tearing assessment. CTa seems to have an equal sensitivity and a higher specificity than MRa for the detection of labral pathology. MRa is better, but not statistically significantly, in demonstrating acetabular and femoral cartilage pathology

    Tannic acid (TA), a plant polyphenol, has been described as having anticarcinogenic, antioxidant, antimutagenic, antimicrobial, antiallergic, antiinflammatory and astringent properties. Resveratrol (RES), a phytoalexin phenolic compound, has been known as an antioxidant, anticarcinogenic, antiinflammatory, antimutagenic, antiproliferative, antiviral, antibacterial, estrogenic and vasodilator agent. Although molecular mechanisms of TA and RES responsible for anticancer activity are yet to be known, there are in vitro studies indicating that these substances contribute to anticancer activity by inducing apoptosis. In this study, the effects of TA and RES in MCF-7 breast cancer cells on apoptotic index, FAS-associated death domain (FADD) and Bak proteins were investigated. Terminal transferase-mediated dUTP nick end-labeling (TUNEL) method was applied for apoptosis and immunohistochemical staining for FADD and Bak proteins. Our study results show that TA and RES increased apoptotic index, percentage ratios of apoptotic proteins Bak and FADD in MCF-7 cell line.Keywords: Bak, Fas-associated death domain (FADD), MCF-7, resveratrol, tannic acidAfrican Journal of Biotechnology Vol. 12(12), pp. 1431-143

    Natural compounds such as resveratrol, tannic acid, and quercetin may help to treat cancer. Tamoxifen is a non-steroidal anti-estrogen drug widely used in the treatment of patients with estrogen receptor-positive breast cancer. The aim of the study was to compare the effects of these natural compounds and tamoxifen in colon adenocarcinoma (CaCo-2) and breast adenocarcinoma (MCF-7) cell lines, on telomerase enzyme activity, cell viability, number of cells and DNA fragmentation. In this study to determine telomerase enzyme activity was used PCR-ELISA kit. To determine cell viability and number of cells were used tripan blue stain. DNA fragmentation was determined by DNA ladder isolation kit. Tannic acid was more effective than resveratrol, with respect to reduction in telomerase activity, cell viability and cell count in breast adenocarcinoma. Tannic acid and tamoxifen was more effective than resveratrol and quercetin telomerase activity, cell viability and cell count in colon adenocarcinoma. Flavonoids such as resveratrol, tannic acid and quercetin which was studied on, has benefical effects on cancer therapy. These effects such as decreasing telomerase enzyme activity, cell viability and number of cells and inducing DNA fragmentation (apoptosis) must be studied for assist to develop new therapeutic pathways. There should be much more sudies in order to discover resveratrol, tannic acid and quercetin and other potential medicines

    WOS: 000390854700003Objective: To investigate clinical evidence for the efficacy of probiotics in the treatment of allergic rhinitis (AR). Methods: A systematic search was conducted to review the results of all randomized, double-blind, placebo-controlled trials by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement. Primary outcome measurements were total nasal and ocular symptom scores (SS) and quality of life (QoL) questionnaires. Secondary outcome measurements were individual nasal SS and immunologic parameters. Results: Twenty-two randomized, double-blind, placebo-controlled studies were included. Seventeen trials showed significant benefit of probiotics clinically, whereas eight trials showed significant improvement in immunologic parameters compared with placebo. All five studies with Lactobacillus paracasei (LP) strains demonstrated clinically significant improvements compared with placebo. Probiotics showed significant reduction in nasal and ocular SS (standardized mean difference [SMD], -1.23, p < 0.001; and SMD, -1.84, p < 0.001; respectively), total, nasal, and ocular QoL scores compared with placebo (SMD, -1.84, p < 0.001; SMD, -2.30, p = 0.006; and SMD, -3.11, p = 0.005; respectively). Although heterogeneity was high, in subgroup analysis, SMD for total nasal and ocular symptoms with patients with seasonal AR and for nasal QoL scores for studies with LP-33 strain were significant and homogenous. Scores of nasal blockage, rhinorrhea, and nasal itching were significantly lower in the probiotic group compared with placebo. The meta-analysis studies SS the Japanese guidelines revealed a significant, homogenous SMD score of -0.34 for individual nasal SS, above the minimal important clinical difference value of 0.3. The T-helper 1 to T-helper 2 ratio was significantly lower in the probiotic group compared with placebo (SMD, -0.78; p = 0.045). Conclusion: Despite high variability among the studies, synthesis of available data provided significant evidence of beneficial clinical and immunologic effects of probiotics in the treatment of AR, especially with seasonal AR and LP-33 strains. With the rising pool of studies, the most promising strains in specific allergies can be revealed and adjuvant therapy with probiotics can be recommended for the treatment of AR.Continuous Education and Scientific Research AssociationWith the exception of data collection, the preparation of this manuscript, including its design and planning, was supported by the Continuous Education and Scientific Research Associatio

    OBJECTIVE: The development of osteoporosis is associated with several risk factors, such as genetic structures that affect bone turnover and bone mass. The impact of genetic structures on osteoporosis is not known. Plasminogen activator inhibitor type-1 regulates the bone matrix and bone balance. This study assessed the correlation between plasminogen activator inhibitor type-1 gene 4G/5G polymorphisms and osteoporosis in a population of Turkish women. METHODS: A total of 195 postmenopausal female patients who were diagnosed with osteoporosis (Group I) based on bone mineral density measurements via dual-energy x-ray absorptiometry and 90 females with no osteoporosis (Group II) were included in this study. Correlations between PAI-1 gene 4G/5G polymorphisms and osteoporosis were investigated through the identification of PAI-1 gene 4G/5G polymorphism genotypes using the polymerase chain reaction. RESULTS: No significant differences in the genotype and allele frequency of 4G/5G plasminogen activator inhibitor type-1 polymorphisms were observed between the two groups, and both groups exhibited the most frequently observed 4G5G genotype. CONCLUSION: No correlation between the development of osteoporosis in the female Turkish population and 4G/5G plasminogen activator inhibitor type-1 gene polymorphisms was observed

    Cosan, Didem Turgut/0000-0002-8488-6405; Sahinturk, Varol/0000-0003-2317-3644; Calis, Ibrahim Ugur/0000-0003-2907-2035WOS: 000390300000020PubMed: 28184327Background: Monosodium glutamate (MSG) is a widely-used flavor enhancer and stabilizer in ready-made or packaged foods. the excessive use of MSG has been shown to increase oxidative stress in different organ systems and causes glucose metabolism disorders, obesity, and coronary diseases. Objectives: in this study, the antioxidant activity of tannic acid was investigated experimentally with respect to its protective effects against overdosed MSG-induced oxidative stress in rats. the study took place in Turkey in August 2013. Methods: Four groups (n = 7) of three-to four-month-old Sprague-Dawley female rats were used in this study. the first group was the control, who were administered saline. the second group received tannic acid (50 mg/kg, 3 days) intraperitoneally (i.p.). the third group received MSG (2 g/kg, 7 days) i.p., and the fourth group received both tannic acid (50 mg/kg, 3 days, pretreatment) and MSG (2 g/kg, 7 days) i.p. the animals were euthanized ten days later. Blood was collected for determining the hematological values and blood glucose levels. Superoxide dismutase (SOD) andmalondialdehyde(MDA) levels were determined in the brain, liver, and kidney homogenates, and in the erythrocyte hemolysate. Histopathological examination of the brain, liver, and kidneys was conducted through hematoxylin-eosin staining. Results: the data showed that the tannic acid treatment statistically decreased the MDA levels in the brain tissues of the group administered MSG and tannic acid (P < 0.001) when compared to the corresponding values of the control group. the SOD activities in the blood hemolysates of the MSGandtannic acid group increased when compared to the corresponding values for the MSGgroup (P < 0.01). Additionally, we found that pretreatment with tannic acid reduced blood glucose levels in comparison to the levels of the MSG group (P = 0.029). the results of our study show that tannic acid pretreatment in adult rats decreased blood glucose levels and oxidative stress. Conclusions: in the literature, it was observed that short-term MSG exposure does not cause significant histological changes in the kidneys, liver, or brain cortex. These findings should be re-evaluated in additional long-term studies
