Variaciones en los contenidos de aceite, proteínas, ácidos grasos y vitamina E de las semillas de calabaza con riego deficitario

In the present study, pumpkin (Cucurbita Pepo L.) was grown under water stress to determine its effects on the chemical composition of the seeds (i.e., oil, protein, fatty acids and vitamin E), in Kayseri, Turkey. Irrigation treatments were designed to supply different portions of depleted moisture within the efficient root zone of the plants (60 cm). The treatments were arranged as supplying 100% (I100), 80% (I80), 60% (I60), 40% (I40), 20% (I20) and 0% (I0) of depleted moisture through a drip irrigation system. The effects of irrigation levels on the oil content of pumpkin seeds were found to be significant (p < 0.01). The oil contents of irrigation treatments varied between 26% (I0, dry) and 64% (I100, full irrigation). However, the effects of deficit irrigation on protein, fatty acids and vitamin E contents were not found to be significant. The vitamin E contents varied from 41.6 – 55.3 mg/100 g; while the protein contents varied from 28.5–37.7%. Six different fatty acids (linolenic, linoleic, oleic, stearic, palmitic and myristic acid) were examined. The average concentration of palmitic, stearic, oleic and linoleic acids ranged from 10.7–12.6%, 6.4–10.4%, 39.6–48.9% and 32.4–35%, respectively. Myristic and linolenic acids were not detected in the pumpkin seeds.En este trabajo se cultivaron calabazas (Cucurbita Pepo L.) en Kayseri, Turquía, con el objetivo de determinar los efectos del estrés hídrico en la composición química de las semillas (aceite, proteínas, ácidos grasos y vitamina E). Los tratamientos de irrigación se realizaron mediante el suministro de diferentes porciones de humedad dentro de la zona de la raíz eficiente de las plantas (60 cm). Los tratamientos se organizaron para suministrar 100% (I100), 80% (I80), 60% (I60), 40% (I40), 20% (I20) y 0% (I0) de humedad controlada a través del sistema de riego por goteo. Los efectos de los niveles de irrigación sobre el contenido de aceite de las semillas de calabaza fueron significativos (p < 0.01). El contenido de aceite en función de los tratamientos de riego varió entre el 26% (I0, seco) y el 64% (I100, riego completo). Sin embargo, los efectos del déficit de irrigación sobre los contenidos de proteínas, ácidos grasos y vitamina E no fueron significativos. Los contenidos de vitamina E variaron entre 41,6 y 55,3 mg/100 g, mientras que los contenidos de proteína variaron entre 28,5 y 37,7%. Se determinaron seis ácidos grasos (linolénico, linoleico, oleico, esteárico, palmítico y mirístico). La concentración promedio de los ácidos palmítico, esteárico, oleico y linoleico osciló entre 10,7–12,6%, 6,4–10,4%, 39,6–48,9% y 32,4–35%, respectivamente. Los ácidos mirístico y linolénico no fueron detectaron en las semillas de calabaza

Analysis of Plio-Quaternary deep marine systems and their evolution in a compressional tectonic regime, Eastern Black Sea Basin

Facies architecture of submarine fans and channel-levee complexes in the Eastern Black Sea Basin and their evolution from the Late Miocene until the present day are studied using a three-dimensional seismic data set covering an area of approximately 1161 km(2). The interpretation of the observations reveals the outcome of the changing interplay between rate of sedimentation and compressional tectonism in the area through time

Fiber enriched diets and radiation induced injury of the gut

WOS: 000180640900009The aim of this study was to evaluate the effect of fiber-enriched defined formula diets (DFDs) on radiation-induced enteropathy. Forty-five male Sprague-Dawley rats were assigned randomly after abdominal irradiation to one of three groups (15 in each group): a fiber-free DFD group, a non-soluble fiber-enriched DFD group, and a soluble fiber-enriched DFD group. They kept their diets respectively for seven days. On day eight, the mesenteric lymph nodes were harvested for bacterial translocation, and segments of jejenum and colon were sampled for microscopic examination. The rats in the fiber-enriched DFD groups lost significantly less body weight than the rats in the fiber-free DFD group. The intestinal structure was the worst in the fiber-free DFD group, intermediate in the soluble fiber-enriched DFD group, and the best in the non-soluble fiber-enriched DFD group with significantly higher measures of villous height and jejunal mucosal thickness. These findings suggest that fiber-enriched DFD may effectively protect intestinal structure against radiation-induced damage by improving mucosal integrity. (C) 2003 Elsevier Science Inc.

Brown tumor of the thoracic spine presenting with paraplegia in a patient with peritoneal dialysis

Secondary and tertiary hyperparathyroidism is an important problem of chronic kidney disease. Brown tumor is a benign, unusual, reactive lesion as a result of disturbed bone remodeling, from long-standing increase in parathyroid hormone level. Brown tumors may cause morbidity due to pressure symptoms on neural structures and spontaneous bone fractures. Herein, we presented a peritoneal dialysis patient with tertiary hyperparathyroidism under calcand calcitriol treatment for 4 years due to refusing of the parathyroidectomy operation. She admitted to hospital for sudden onset back pain with difficulty in gait and walking, and imaging studies showed an expansile mass lesion in the thoracic spine. She was operated for mass and diagnosed with brown tumor. After operation, she lost the ability of walking than become paraplegic and she underwent rehabilitation program. Preventive measures including calcitriol and cinacalcet may cause a modest decrease in parathyroid hormone levels but it should be remembered for the development of bone complications such as brown tumor formation in patients with moderate elevated PTH levels, especially those with tertiary hyperparathyroidism. Parathyroidectomy should be performed without delay in these cases

Multiple urinary tract infections are associated with genotype and phenotype in adult polycystic kidney disease.

Background Urinary tract infections (UTI) are one of the important clinical presentations in patients with autosomal dominant polycystic kidney disease (ADPKD). The association between UTI among genotypic and phonotypic properties of ADPKD patients is still obscure. Thus, we investigated the relationship between UTI and polycystin gene mutation with total kidney volume. Methods Forty patients with ADPKD patients with a history of more than two UTI and age-gender-matched 40 ADPKD patients without UTI history enrolled in the study. Ambulatory blood pressure monitoring was performed in all participants. Magnetic resonance imaging (MRI) was performed with a 1.5-T system, and total kidney volumes were calculated using mid-slice technique. To determine PKD1 and PKD2 genotype, we performed molecular and genetic tests involving the following steps: DNA isolation, next-generation sequencing (NGS) and data analysis. Results ADPKD patients with UTI had lower eGFR values than those without UTI [64.9 (32.2-100.8) vs 89.5 (59.0-110.0) (p = 0.041)]. In addition, patients with UTI had significantly increased height-adjusted total kidney volume than patients without UTI [950 (290-1350) vs 345 (243-780.0) (p = 0.005)]. Multiple logistic regression analysis showed that the PKD1-truncating mutation and hTKV independently predicted UTI. The sensitivity and specificity of hTKV were 65% and 77% (cutoff > 727 cm(3)) with an area of under the ROC curve of 0.70 (95% CI 0.56-0.85, p = 005). Conclusions ADPKD patients with larger kidneys and PKD1 mutation are susceptible to increased risk of multiple UTI. Additionally, renal function decreased in ADPKD patients with multiple UTI history

Hypoxia-inducible factors in arteriovenous fistula maturation: A prospective cohort study

Background Neointimal hyperplasia is the main cause of arteriovenous fistula (AVF) failure. Hypoxia-inducible factors (HIFs) factors are associated with neointimal hyperplasia. Thus, we investigated the association between HIF-2 alpha (HIF-2 alpha) and AVF maturation in end-stage kidney disease (ESKD) patients. Methods This prospective cohort study was conducted in 21 voluntary healthy subjects and 50 patients with ESKD who were eligible for AVF creation. Inclusion criteria were being ESKD patients without a history of AVF surgery and dialysis. Eight patients excluded from the study due to having unavailable veins six patients were excluded due to acute thrombosis after surgery. One patient lost to follow-up. A total of 35 patients were included in final analysis. The blood samples were collected a day before the AVF surgery for biochemical parameters and HIF-2 alpha measurement. HIF-2 alpha levels were measured by the ELISA method. Results Compared with healthy subjects, ESKD patients had a significantly higher level of HIF-2 alpha. [1.3 (1.0-1.9) vs 2.2 (1.6-3.0)] (P = .002). Patients were divided into two groups after the evaluation of AVF maturation, as the mature group (n = 19) and the failure group (n = 16). Serum HIF-2 alpha level was 1.7 (1.1-1.8) in the mature group; however, it was 3.1 (2.8-3.3 in failure group (P .001). Multiple logistic regression analyses showed that HIF-2 alpha independently predicted AVF maturation. The ROC curve analysis showed that HIF-2 alpha > 2.65 predicted AVF maturation failure with the 87% sensitivity and 94% specificity [AUC:0.947, 95% CI (0.815-0.994),P .001]. Conclusions HIF-2-alpha levels were higher in ESKD patients than healthy subjects. HIF-2-alpha could be a marker of AVF maturation failure
