Hb South Florida is a rare hemoglobin beta chain variant that is not associated with any clinical disorder. We report a heterozygous Hb South Florida (β1(NA1)Val>Met, GTG>ATG; HBB:c.4G>A) case determined during a premarital screening program. This hemoglobin variant can be identified with high performance liquid chromatography analysis confirmed with DNA sequencing. We emphasize in our study the importance of an interdisciplinary collaborative study at the provincial basis for the success of the hemoglobinopathy control program.

Objective: To isolate phytase producing Bacillus sp. from soil samples of Turkey, and opti- mize the growth conditions for maximum production of phytase. Material and Methods: The screening of isolates was performed on phytase screening me- dium. The best producer was selected. Phytase activity was determined by measur ing the amount of liberated inorganic phosphate. Optimal culture conditions and fermentation pa- rameters for phytase production were assessed. Results: 236 Bacillus sp. strains isolated. The best phytase producing strain showed higher enzyme yield in the presence of wheat bran and lactose as carbon source, meat extract as organic nitrogen source, CaCl 2 as metal source. 0.3% as phytate concentration was found to be best. In the physical parameters, the best results was obtained at 35°C, pH 7.5, 200 rpm as agitation rate, 2-4% as inoculum size and 48 h as inoculum age. A new medium was obtained by optimizing the incubation conditions of phytase production from Bacillus sp. EBD 9-1. In this medium, enzyme yield was enhanced 62% compared to basal medium. Conclusion: The present study suggests that the novel Bacillus sp. phytase enzyme may have wide industrial application, and can be used as an animal feed additive.

Objective: Although the mechanism is still not so clear, ischemia modified albumin is produced as a result of the occurrence of changes in metal binding regions on the albumin with the production of reactive oxygen species. But it is not known whether this change is the cause or the result of different states. This study is designed to investigate the correlation between hypohemoglobinemia, hypoxemia due to blood loss and IMA. Methods: The research is carried out with 83 patients (28 Male, 55 Female; mean age: 51±22 year) and 19 subject as control group (7Male, 12 Female; mean age 35±18 year). Patients were divided into three sub-groups according to their hemoglobin levels (<8, 8-10, 10-12 g/dL). Additionally, same patients were divided into second sub-group according to their follow-up status as outpatient (40 male, 15 female, mean age: 48 ± 20 year), postoperative (8 male, 11 female, mean age: 49 ± 24 year) and intensive care unit (6 male, 5 female; mean age: 64±20 year) patients. To determine the IMA levels the measurement method based on albumin cobalt binding assay was used. Results: In IMA levels, no significant difference is found between the mild (Hb: 10-12 g/dL) [(n=47; 0,61±0,23 ABSU)], moderate (Hb: 8-10 g/dL) [(n=26; 0.58±0.24 ABSU)] and severe (Hb: <8 g/dL) [(n=9; 0.62±0.12 ABSU)] anemia groups. However, because of acute blood loss related acute hypoxemia; IMA levels of the postoperative patients are statistically higher as compared to control group. As compared to control groups, no statistically significant difference is observed in the levels of the serum IMA in the outpatient group who had minimally invasive surgery and in the intensive care patient group. Conclusion: Our results suggest that; if mycardial oxygenization is questioned in cases of acute and heavy blood loss, ischemia modified albumin is not a valuable test for the indicator of the myocardial ischemia.
目的:虽然机制尚不清楚,但缺血修饰白蛋白的产生是由于白蛋白上的金属结合区随着活性氧的产生而发生变化。但尚不清楚这种变化是不同状态的原因还是结果。本研究旨在探讨失血引起的低血红蛋白血症、低氧血症与IMA的相关性。方法:对83例患者进行研究,其中男28例,女55例;平均年龄:51±22岁),对照组19例(男7例,女12例;平均年龄(35±18岁)。根据血红蛋白水平(<8、8-10、10-12 g/dL)将患者分为3个亚组。根据门诊随访情况(男性40例,女性15例,平均年龄48±20岁)、术后随访情况(男性8例,女性11例,平均年龄49±24岁)、重症监护室随访情况(男性6例,女性5例;患者平均年龄:64±20岁。采用白蛋白钴结合法测定IMA水平。结果:在IMA水平上,轻度(Hb: 10-12 g/dL) [n=47;0,61±0,23 ABSU)],中度(Hb: 8-10 g/dL) [(n=26;0.58±0.24 ABSU)]和重度(Hb <8 g/dL) [(n=9;0.62±0.12 ABSU)]贫血组。然而,由于急性失血相关的急性低氧血症;术后患者IMA水平明显高于对照组。与对照组相比,微创手术门诊组和重症监护组的血清IMA水平无统计学差异。结论:本研究结果表明;如果在急性和大量失血的情况下心肌氧合受到质疑,缺血修饰白蛋白不是一个有价值的检测心肌缺血的指标。

Objective: In recent years, metabolic syndrome, which is a serious health problem, enhancing the effect of oxidative stress and lipid peroxidation, which is a natural antioxidant resveratrol, a polyphenol structure, the use of this area has brought. The present study aimed to evaluate the influence of resveratrol (RSV) treatment on heart, kidney and hepatic tissue malondialdehyde (MDA), nitric oxide (NO), superoxide dismutase (SOD) and catalase (CAT) levels in high fructose feeding rats which form an experimental metabolic syndrome model and compared to pre-treatment of metabolic syndrome group and the control group values. Methods: Wistar/albino rats (n=15) were used in the present study. Rats were divided equally into 3 groups as control, created group of metabolic syndrome and metabolic syndrome plus resveratrol treatment. At the end of the experimental period, tissue MDA, NO, SOD and CAT levels were studied manual spectrophotometric methods after homogenization of tissues. Results: The result of the study, a significant increase in heart and liver tissue MDA levels, and heart, kidney, liver tissue NO levels were observed in the metabolic syndrome group compared to the controls (p<0.05), following treatment with resveratrol significantly decreases were observed to be close to the control values. Kidney and liver tissue catalase activity statistically significant decrease in metabolic syndrome group compared to the controls, (p=0.019 and p=0.021, respectively), kidney and liver tissue catalase activity similar to control values after treatment with resveratrol, a significant increase was observed (p=0.011 and p=0.58), but changes in the activity of SOD has not been as significant as catalase (p>0.05). However, hepatic SOD activity of resveratrol treatment group compared with the control group, a significant increase was recorded in the treated group (p=0.011). Conclusion: These results suggest probably antioxidant effects of resveratrol to reduce oxidative stress in the liver and kidney tissue which is an important role in metabolism. Against tissue damage generated by exogenous fructose, resveratrol is effective in preventing tissue damage with a direct or indirect effect shows.
目的:近年来,代谢综合征这一严重的健康问题,增强了氧化应激和脂质过氧化的作用,其中白藜芦醇是一种天然抗氧化剂,具有多酚结构,这一领域的应用已经带来。本研究旨在评价白藜芦醇(resveratrol, RSV)处理对形成实验性代谢综合征模型的高果糖喂养大鼠心脏、肾脏和肝脏组织丙二醛(MDA)、一氧化氮(NO)、超氧化物歧化酶(SOD)和过氧化氢酶(CAT)水平的影响,并与代谢综合征治疗前组和对照组的数值进行比较。方法:采用Wistar/白化大鼠15只。将大鼠平均分为3组,分别作为对照组、代谢综合征组和代谢综合征加白藜芦醇治疗组。实验结束时,组织匀浆后,采用手工分光光度法测定组织中MDA、NO、SOD和CAT水平。结果:研究结果:代谢综合征组与对照组相比,心、肝组织MDA水平及心、肾、肝组织NO水平均显著升高(p0.05)。而白藜芦醇治疗组肝脏SOD活性较对照组显著升高(p=0.011)。结论:白藜芦醇可能具有降低肝脏和肾脏组织氧化应激的抗氧化作用,在机体代谢中起重要作用。对于外源性果糖引起的组织损伤,白藜芦醇具有直接或间接的预防作用。

Aim: Fruits and vegetables are the main sources of antioxidant compounds and vitamins. In nature, α-tocopherol, is the most abundant and biologically active form of Vitamin E. The current study was aimed to investigate the antioxidant activity and α-tocopherol content of commercial and freshly squeezed fruit juices. Material and Methods: Apple, apricot and tomatoes fresh and commercial fruit juices were evaluated for their potential antioxidant activities using DPPH and ABTS + radical scavenging capacity assays. The total phenolic and flavonoid content of juices were determined by Folin- Ciocalteu and Aluminium chloride colorimetric methods respectively. The α-tocopherol con- tents of juices were investigated by HPLC-UV chromatographic method. Results: The highest α-tocopherol concentration was found in freshly squeezed tomatoes juice (0.0761±0.20mg/100g) the total phenolic content of freshly squeezed fruit juices mea- sured by Folin-Ciocalteu assay, ranged between 2.10-12.83mg gallic acid equivalents (mg GAE/100ml). The total flavonoid content of samples was expressed as quercetin equiva- lents (mg QE/100ml). The commercial tomatoes juice showed higher content of flavonoid (4.10±0.0126 mg QE/100ml), followed by freshly squeezed apple and apricot fruit juices. The fresh fruit juices of tomatoes showed the lowest content of flavonoid and highest content of total phenolic compounds. Freshly squeezed apple juice and apricot juice were found to exert higher antioxidant activities in ABTS+ and DPPH assays respectively. Conclusion: It was observed that α-tocopherol content and antioxidant capacities and total phenolic and flavonoid concentrations of freshly squeezed juices were higher than commer- cial ones.

Conclusion: It was observed that α-tocopherol content and antioxidant capacities and total phenolic and flavonoid concentrations of freshly squeezed juices were higher than commer- cial ones.","PeriodicalId":23355,"journal":{"name":"Turkish Journal of Biochemistry-turk Biyokimya Dergisi","volume":"10 1","pages":"215-220"},"PeriodicalIF":0.7,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84342453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective: Behcet's disease (BD) is a chronic, inflammatory, multisystem vasculitis and the etiology is not yet fully understood. Nitric Oxide (NO) is an important molecule for the vascular system which synthesised by the Nitric Oxide Synthase (NOS) enzyme. Asymmetric dimethylarginine (ADMA) is an endogenous inhibitor of NOS. Therefore, we aimed to investigate levels of the ADMA and its relation with exacerbations in BD patients. Methods: The subjects enrolled in this study were recruited from 34 patients with BD and 34 healthy controls. Serum levels of ADMA, arginine and citrulline were measured by HPLC with fluorescence detection. The ESR and CRP levels analyzed by routinely used methods. Results: In contrast to information in the literature, ADMA levels were found to be decreased in BD patients when compared to control. Inversely, Arginine and Citrulline levels were significantly increased in BD patients. Increased Arginine/ADMA ratios were found in the patient group. There was an inverse relation between ADMA and CRP levels. Arginine values were also correlated CRP and Citrulline levels. Conclusion: One of the reasons of high number of BD attacks in young age may be low levels of ADMA. Our study suggests that the reduced levels of ADMA in patients group may impose a possible preventive role to ADMA through decrease of NO-mediated inflammation and exacerbations of BD with aging.
目的:白塞病是一种慢性、炎症性、多系统血管炎,其病因尚不完全清楚。一氧化氮(NO)是由一氧化氮合酶(NOS)合成的血管系统的重要分子。不对称二甲基精氨酸(ADMA)是一种内源性NOS抑制剂,因此,我们旨在研究ADMA水平及其与BD患者病情恶化的关系。方法:选取34例BD患者和34例健康对照者作为研究对象。采用荧光高效液相色谱法测定血清ADMA、精氨酸和瓜氨酸水平。常规方法分析ESR和CRP水平。结果:与文献信息相反,与对照组相比,BD患者的ADMA水平降低。相反,精氨酸和瓜氨酸水平在BD患者中显著升高。患者组精氨酸/ADMA比值升高。ADMA与CRP水平呈负相关。精氨酸值也与CRP和瓜氨酸水平相关。结论:ADMA水平低可能是青年BD发病高发的原因之一。我们的研究表明,患者组中ADMA水平的降低可能通过减少no介导的炎症和随着年龄增长的BD恶化而对ADMA起到预防作用。
