Protein-phenolic interactions in lentil and wheat crackers with onion skin phenolics: effects of processing and in vitro gastrointestinal digestion.

This study aimed to evaluate the protein-phenolic interaction in functional crackers made of wheat/lentil flour with onion skin phenolics (onion skin powder: OSP, onion skin phenolic extract: OSE, or quercetin: Q) after in vitro gastrointestinal digestion. Phenolic/antioxidant recovery in crackers was lower with higher levels of phenolic addition. In vitro gastrointestinal digestion procedure was applied for crackers prepared/cooked with onion skin phenolics (functional crackers) or crackers consumed with onion skin phenolics (co-digestion). Functional crackers had similar nutritional attributes (p > 0.05), however they had lower L* values, and higher a* values. A higher concentration of OSP/OSE caused a decrease in the b* value while it was increased with the quercetin addition. Phenolic/antioxidant recovery in functional crackers was decreased by increasing the ratio of phenolic supplements. The amount of quercetin 7,4-diglucoside was lower than the theoretical value whereas the amount of quercetin was higher in functional crackers. The phenolic bioavailability index (BIP) of co-digested crackers was higher than that of functional crackers, whereas antioxidant bioavailability index (BIA) was mostly similar. Quercetin was only identified in functional wheat/lentil crackers with OSE. After digestion (1) TCA-precipitated peptides of the wheat crackers could not be identified, whereas that of co-digested lentil crackers was more abundant, (2) level of free amino groups of co-digested/functional crackers were lower than the control except for the co-digested sample of lentil cracker with quercetin.

Determination of the changes in sunflower oil during frying of leavened doughs using response surface methodology.

In this study, the effect of dough salt content, frying temperature and time on the conjugated diene values, polymer triglyceride content, total polar material content, viscosity, and color values of the sunflower oil during frying of leavened doughs was determined using response surface methodology. Fifty repeated frying operations were applied in the same day at 160-200 °C for 1-5 min and doughs with 0-2% salt content. According to the results of the study, frying temperature, frying time and dough salt content were significantly (p < 0.05) affected total polar material content, polymer triglyceride content, viscosity and a* and b* color values of oil samples, whereas dough salt content did not affect the L* color values and conjugated diene value of oil significantly (p > 0.05). To minimize the oxidation products of frying oil, the frying process can be applied at 160 °C for 1 min using dough with 1.97% salt content.

Interaction of lentil protein and onion skin phenolics: Effects on functional properties of proteins and in vitro gastrointestinal digestibility.

The effect of protein-phenolic interactions on the functional properties of lentil protein and in vitro gastrointestinal digestibility in different systems (extract solution, protein-phenolic solution, and emulsion) was studied. The presence of phenolic compounds negatively affected the foaming and emulsion properties of lentil protein. During in vitro gastrointestinal digestion, total phenolic content (TPC) and antioxidant capacity of the samples were decreased with the presence of lentil protein at the initial phase, however, they were found to be the highest in emulsions at the intestinal phase. The amount of protocatechuic acid and phenolic acid derivative was increased at the intestinal phase, while that of other phenolic compounds was decreased. Quercetin was not detected at the intestinal phase in all systems, while its glycoside derivatives were determined, which were the highest in emulsions. Anthocyanins were also the highest in extract solution among all systems. Protein-phenolic interactions had a significant effect on functional properties of lentil proteins, and bioaccessibility or antioxidant capacity of phenolic compounds.

Centralization of mammography reporting with mobile trucks: Turkish experience.

Screening via mammography is a complex process to be implemented. OBJECTIVE: To report the initial results and the effectiveness of newly implemented Turkey's population based breast cancer screening program performed for 40-69 years old women; and effectiveness of the newly implemented out-sourcing mobile trucks and national central report center. The study is conducted prospectively in one year (March 2016-March 2017) in all 81 provinces of Turkey. Mammography images were transferred via on-line web based system to the central reporting center. BI-RADS Scores and KETEM models (Mobile vs. Stationary) were the parameters were compared. In total mammography images of 414.802 patients were transferred from 155 KETEMs to the central reporting center. From these patients; 95.872 (23,1%) were aged between 40 and 44. Among all images, 21.999 (5,3%) were BI-RADS 0-4-5, 391.123 (94,3%) were BI-RADS 1-2. Totally recall rate of the national reporting center was 5.3%. Number of patients screened per day were significantly higher in out-sourcing mobile trucks compared to stationary KETEMs (31.8 vs. 8.9; p < 0.05). This is the first and the largest breast cancer screening study which results of a population based mammography screening for 40-69 years old women are evaluated at the same time with the evaluation of the efficacy of newly implemented centralized reporting center and the mobile screening trucks in comparison with stationary cancer screening centers. According to the initial results; Turkey's newly implemented population based breast cancer screening system seems to be feasible and effective.

Survival of gynecological cancers in Turkey: where are we at?

OBJECTIVE: To investigate the 5-year relative survival rates in gynecological cancers diagnosed and treated in Turkey by year 2009 and to compare the results with developed countries. METHODS: Data of patients diagnosed for ovarian, corpus uteri or cervix uteri cancer at year 2009 are collected from 9 national cancer registry centers. Date of deaths are retracted from governmental Identity Information Sharing System (KPS). In order to calculate relative survival rates, national general population mortality tables are obtained from Turkish Statistical Institute (TurkStat). Hakulinen method is used for computing curves by R program. Data for European, Asian and some developed countries were obtained from official web pages. RESULTS: A total of 1,553 patients are evaluated. Among these, 713 (45.9%) are corpus uteri cancers, while remaining 489 (31.5%) are ovarian and 351 (22.6%) are cervix uteri. Five-year overall relative survival rates are 85%, 50%, and 62% for corpus uteri, ovarian, and cervix uteri, respectively. These figures are between 73%-87% for corpus uteri, 31%-62% for ovarian and 61%-80% for cervix uteri in developed countries. Stage is the most important factor for survival in all cancers. Five-year relative survival rates in corpus uteri cancers are 92%, 66%, and 38% for localized, regional, and distant metastatic disease, respectively. These figures are 77%, 57%, and 29% for ovarian; 80%, 50%, and 22% for cervix uteri. CONCLUSION: This is the first report from Turkey giving national overall relative survival for gynecological cancers from a population based cancer registry system.

Trends of Gynecological Cancers in Turkey: Toward Europe or Asia?

OBJECTIVE: The aim of this study was to evaluate nationwide gynecological cancer trends in Turkey. METHODS: National cancer registry data (2009-2013) of Turkish Ministry of Health were evaluated. Ovarian, cervical, endometrial, vulvar, vaginal, and tubal cancers are evaluated with respect to age of diagnosis, incidence rates within years, stage, histological distributions, and mortality rates. Data were collected from active cancer registry centers, which increased from 23% in 2009 to 47.5% coverage of the whole population by 2012, and mortality data (2010-2015) were obtained from the Turkish Statistical Institute. RESULTS: A total of 16,023 gynecological cancers were evaluated among 116,940 female patients with cancer (13.7%). Average incidence for gynecological cancers was 22.7 of 100,000, representing 8437 total new cases annually. Incidence changes within time were not statistically significant, when evaluated for each tumor type. Estimated risk of gynecological cancer development before the age of 80 years was 3.08% (95% confidence interval, 3.07-3.09). The most common gynecological cancers were uterine corpus cancers, which were followed by ovarian and cervical carcinomas. Ovarian and uterine cancer incidences were closer to European levels rather than Asian countries, whereas cervical cancer incidence was extremely low. Gynecological cancers constituted an important fraction of cancer-related mortality in women by comprising approximately 10.35% of cancer-related deaths. Mortality rates due to gynecological cancers did not show a statistically significant increase within years. CONCLUSIONS: This is the first national cancer registry report to be published for gynecological cancers by the Turkish Governmental Department. As a result, Turkish gynecological cancer epidemiological data were consistent with the data obtained from European and developed countries rather than Asian countries, except for cervical cancer incidence, which is extremely low.

Trans fatty acids and fatty acid composition of mature breast milk in turkish women and their association with maternal diet's.

The aim of this study was to determine the fatty acid composition and trans fatty acid and fatty acid contents of breast milk in Turkish women and to find the effect of breastfeeding mothers' diet on trans fatty acid and fatty acid composition. Mature milk samples obtained from 50 Turkish nursing women were analyzed. Total milk lipids extracts were transmethylated and analyzed by using gas liquid chromatography to determine fatty acids contents. A questionnaire was applied to observe eating habits and 3 days dietary records from mothers were obtained. Daily dietary intake of total energy and nutrients were estimated by using nutrient database. The mean total trans fatty acids contents was 2.13 +/- 1.03%. The major sources of trans fatty acids in mothers' diets were margarines-butter (37.0%), bakery products and confectionery (29.6%). Mothers who had high level of trans isomers in their milk consumed significantly higher amounts of these products. Saturated fatty acids, polyunsaturated fatty acids and monounsaturated fatty acids of human milk constituted 40.7 +/- 4.7%, 26.9 +/- 4.2% and 30.8 +/- 0.6% of the total fatty acids, respectively. The levels of fatty acids in human milk may reflect the current diet of the mother as well as the diet consumed early in pregnancy. Margarines, bakery products and confectionery are a major source of trans fatty acids in maternal diet in Turkey.

Fatty acid, triacylglycerol, phytosterol, and tocopherol variations in kernel oil of Malatya apricots from Turkey.

The fatty acid, sn-2 fatty acid, triacyglycerol (TAG), tocopherol, and phytosterol compositions of kernel oils obtained from nine apricot varieties grown in the Malatya region of Turkey were determined ( P<0.05). The names of the apricot varieties were Alyanak (ALY), Cataloglu (CAT), Cöloglu (COL), Hacihaliloglu (HAC), Hacikiz (HKI), Hasanbey (HSB), Kabaasi (KAB), Soganci (SOG), and Tokaloglu (TOK). The total oil contents of apricot kernels ranged from 40.23 to 53.19%. Oleic acid contributed 70.83% to the total fatty acids, followed by linoleic (21.96%), palmitic (4.92%), and stearic (1.21%) acids. The s n-2 position is mainly occupied with oleic acid (63.54%), linoleic acid (35.0%), and palmitic acid (0.96%). Eight TAG species were identified: LLL, OLL, PLL, OOL+POL, OOO+POO, and SOO (where P, palmitoyl; S, stearoyl; O, oleoyl; and L, linoleoyl), among which mainly OOO+POO contributed to 48.64% of the total, followed by OOL+POL at 32.63% and OLL at 14.33%. Four tocopherol and six phytosterol isomers were identified and quantified; among these, gamma-tocopherol (475.11 mg/kg of oil) and beta-sitosterol (273.67 mg/100 g of oil) were predominant. Principal component analysis (PCA) was applied to the data from lipid components of apricot kernel oil in order to explore the distribution of the apricot variety according to their kernel's lipid components. PCA separated some varieties including ALY, COL, KAB, CAT, SOG, and HSB in one group and varieties TOK, HAC, and HKI in another group based on their lipid components of apricot kernel oil. So, in the present study, PCA was found to be a powerful tool for classification of the samples.
