Despite this, conceptual advances in the understanding of its pathobiology have remained elusive for over half a century. As with all cancers, it is metastasis (i.e. secondary cancer formation) and its consequences that present the most significant biomedical and clinical challenges to the host, carers and healthcare payors, as well as the researchers. Pre-metastatic or metastataic PCa is frequently treated by hormone-based therapies aiming at androgen-down-regulation. However, this classic method is only effective for a limited time and new approaches are necessary (a) to improve the understanding of the pathobiology of PCa and (b) to develop new therapies for it, as well as improving the existing ones. In this article, we present an overview of the pathobiology of PCa and evaluate the evidence for the role of functional voltage-gated sodium channel (VGSC) expression in disease progression. We also discuss the possibility that VGSC blockers could be effective as novel anti-PCa drugs for clinical management of the metastatic phenotype.","PeriodicalId":14521,"journal":{"name":"IUFS Journal of Biology","volume":"10 1","pages":"1-17"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81129539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the systemic NO response to acute exercise in untrained diabetic and nondiabetic patients with atherosclerotic coronary artery disease (CAD). This is a prospective, clinical study consisting of three groups. Group A (n=50) consisted of nondiabetic CAD patients,group B (n=20) consisting of diabetic, CAD patients and group C (n=20) of healthy controls. All patients underwent a standard symptom limited treadmill exercise test according to the modified Bruce protocol after 24 hours low nitrite/ nitrate diet. End products of nitric oxide metabolism (NOx) were determined as the half life of NO is very short. Basal serum NOx levels of both diabetics (24±8.4μmol/L,p<0.0001)and nondiabetics (43.5±13.7μmol/L, p<0.01) were significantly lower compared to controls (66.5±3.4μmol/L). Only in the nondiabetic, CAD patient group was an increase in NOx levels observed with exercise. No increase in NOx with exercise was observed for the diabetic. CAD patient group or for the control group. In normal controls exercise induced no significant change in NOx levels. Exercise induced increase in systemic NOx levels in patients with atherosclerotic disease may indicate a compensatory mechanism which is not present or diminished in the diabetic subgroup .","PeriodicalId":14521,"journal":{"name":"IUFS Journal of Biology","volume":"156 1","pages":"85-91"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73733759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The control of these infections is done by water treatment. It's very important to monitor faecal and total coliform bacteria for the examination of microbiologic quality of drinking water. In addition, the determination of total mesophilic aerobic bacteria growing in 22 - 37 oC is also used in measure of bacterial pollution. In our study 88 bottled water belong 22 different brands were examined. The samples of water that are taken from plastic bottles of 19 L were examinated for total mesophilic aerobic bacteria, faecal coliform, total coliform, Aeromonas spp., Pseudomonas spp ., presence of free living amoeba. Faecal coliform, total coliform, Aeromonas spp., Pseudomonas spp . and the existence of free living ameoba is determined by membrane filtration; and the total mesophilic aerobic bacteria numbers determined by pour plate method. It has been found that all of the examined samples of this study are not acceptable according to the standarts of TSE, EPA and WHO. Although we took four different samples from the same brand, we found level of different pollutions. Resumably, method of cleaning up the bottles and the unhealthy conditions of filling facilities might cause these differences. In conclusion, our study showed that it's very important that the systematic microbiological monitoring and control of bottled water which is used as drinking water.

A very limited number of investigations for fatty acid patterns and α-tocopherol contents of the seed oils were reported in this genus. Some differences were observed in total oil (18.8-24.0%) and α-tocopherol contents (1.66-46.03%) between species. Major unsaturated fatty acids were α-linolenic (38.70-41.05%), linoleic (16.13-18.38%) and oleic acids (11.86-12.96%) respectively. Palmitic (6.327.71%), E¤-linolenic (6.36-6.92%) and stearic (2.15-2.32%) acids showed considerable levels. Other fatty acid concentrations were at minor concentrations below 1 % of the seed oils. Total oil content in addition to oleic and α-linolenic acids quantified at higher levels in endemic O. bracteosum . The other fatty acids and α-tocopherol were observed at higher concentrations in O. thracicum . Some variations were examined in quantities, total percentages and the ratios of saturated and unsaturated fatty acids as additional chemotaxonomic markers. Differences for whole series of fatty acids were not significant between species but, significantly difference was found based on six calculated ratios of the fatty acids (p<0.05). Investigated Onosma species could be evaluated as the alternative wild sources for the production of essential fatty acids (EFA) including α-linolenic (ω-3), linoleic and unusual E¤-linolenic (ω-6) acids.","PeriodicalId":14521,"journal":{"name":"IUFS Journal of Biology","volume":"43 1","pages":"75-83"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85580413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we focused on morphofunctional diversities of different regions of the digestive tract and their feasible physiological and evolutionary implications. We used the following standard histochemical techniques: contained periodic acid-Schiff (PAS), Alcian blue (AB) pH 1.0 and 2.5, toluidin blue, aldehyde fucsin and bromfenol blue. For lectin histochemistry, five different lectins were used namely, DBA, WGA, PNA, ConA and UEA-I. The glycoconjugate produced in the fundic part of the stomach is composed of mainly neutral mucins and strongly sulphated acid mucins with α-N-acetyl-D-galactosamine and N-acetyl-β-D-glucosamine residues. Besides, the glycoconjugate secreted from the small intestine consists of mostly sulphated sialo and neutral mucins with N-acetyl-β-D-glucosamine moieties. It can be concluded that the differences in glycoconjugates types and the sugar residues in two digestive tract regions of Rana ridibunda may be related to special functions and rheological characteristics of the mucins.","PeriodicalId":14521,"journal":{"name":"IUFS Journal of Biology","volume":"39 1","pages":"93-104"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75091188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deficiency of thyroid hormones causes many metabolic processes to slow down. The maintenance of optimal health requires an adequate supply of carbohydrates, proteins and lipids, and macronutrients, micronutrients, and trace elements. In this work, the serum content of the trace elements; Zn, Cu, Mn, and Se in hypothyroidism patients was determined and compared to that of normal subjects. Seventy three ypothyroid patients and fifty normal healthy control persons participated in this study. Serum zinc and copper were determined using flame atomic absorption spectrophotometer, while determination of manganese and selenium were done using flameless atomic absorption spectrophotometer. The results showed that serum zinc and selenium level of hypothyroidism patients are significantly lower (p 0.05) in serum copper. The results of this work as discussed indicate, the role of these trace elements in many metabolic process either as essential nutrients or as cofactors for different enzymes contributed directly or indirectly to the hypothyroidism. Consequently, the results of this study suggest that the metabolism of zinc, manganese, and selenium is abnormal in hypothyroidism disease.","PeriodicalId":14521,"journal":{"name":"IUFS Journal of Biology","volume":"106 1","pages":"121-126"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85337120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
