Tumor growth reduction is regulated at the gene level in Walker 256 tumor-bearing rats supplemented with fish oil rich in EPA and DHA

We investigated the effect of fish oil (FO) supplementation on tumor growth, cyclooxygenase 2 (COX-2), peroxisome proliferator-activated receptor gamma (PPAR&#947;), and RelA gene and protein expression in Walker 256 tumor-bearing rats. Male Wistar rats (70 days old) were fed with regular chow (group W) or chow supplemented with 1 g/kg body weight FO daily (group WFO) until they reached 100 days of age. Both groups were then inoculated with a suspension of Walker 256 ascitic tumor cells (3×107 cells/mL). After 14 days the rats were killed, total RNA was isolated from the tumor tissue, and relative mRNA expression was measured using the 2-&#916;&#916;CT method. FO significantly decreased tumor growth (W=13.18±1.58 vsWFO=5.40±0.88 g, P<0.05). FO supplementation also resulted in a significant decrease in COX-2 (W=100.1±1.62 vsWFO=59.39±5.53, P<0.001) and PPAR&#947; (W=100.4±1.04vs WFO=88.22±1.46, P<0.05) protein expression. Relative mRNA expression was W=1.06±0.022 vsWFO=0.31±0.04 (P<0.001) for COX-2, W=1.08±0.02vs WFO=0.52±0.08 (P<0.001) for PPAR&#947;, and W=1.04±0.02 vs WFO=0.82±0.04 (P<0.05) for RelA. FO reduced tumor growth by attenuating inflammatory gene expression associated with carcinogenesis.

The effect of irradiation and thermal process on beef heme iron concentration and color properties

The aim of this study was to evaluate the influence of irradiation and thermal process on the heme iron (heme-Fe) concentration and color properties of Brazilian cattle beef. Beef samples (patties and steaks) were irradiated at 0-10 kGy and cooked in a combination oven at 250 ºC for 9 minutes with 70% humidity. Total iron and heme iron (heme-Fe) concentrations were determined. The data were compared by multiple comparisons and fixed- effects ANOVA. Irradiation at doses higher than 5 kGy significantly altered the heme-Fe concentration. However, the sample preparation conditions interfered more in the heme-Fe content than did the irradiation. Depending on the animal species, meat heme iron levels between 35 and 52% of the total iron are used for dietetic calculations. In this study the percentage of heme-iron was, on average, 70% of the total iron showing that humidity is an important factor for its preservation. The samples were analyzed instrumentally for CIE L*, a*, and b* values.

Influence of color on acceptance and identification of flavor of foods by adults

The sensory characteristics color and flavor of food play an important role not only in the selection, but also in the determination of consumption, satiation, and ingestion. With the objective to determine and evaluate the influence of color on the acceptance and identification of flavor of foods for adults, sensory analysis was performed on jellies by non-trained tasters of both sexes aged between 18 and 60 years (1750 tests). A hedonic scale and combinations of five colors (red, yellow, green, blue and purple) and three flavors (strawberry, pineapple, and limes) were used in the acceptance test totaling 15 samples. In the duo-trio discrimination test, together with the reference sample (R), one sample identical to the reference and another of identical color and different flavor were offered, and the judges were requested to identify the sample that was different from the reference sample. The colors used did not influence the acceptance of the samples (P > 0.05), and as there was not significant interaction between color and flavor. However, the limes flavor negatively influenced acceptance when compared to the other flavors. With regard to flavor differentiation, the colors used did not influence flavor identification (P > 0.05); However, differentiated behavior was identified between females and males, and the latter were more error-prone. Therefore, under the experimental conditions tested, color did not influence the acceptance and identification of the flavor of the samples by adults.

Purple urine bag syndrome in end-stage chronic kidney disease

Introduction: When faced with violet, purple or purplish-blue urine, clinicians should consider urinary tract infection in their differential diagnosis. Case report: A 60-year-old woman with end-stage kidney disease and non-adherence to renal replacement therapy was admitted to our hospital for placement of hemodialysis catheter. During her hospitalization she had purple urine, and purple urine bag syndrome (PUBS) was diagnosed. She was effectively treated with antibiotics and her urine returned to a dark yellow color. Discussion: Although this condition is often easily treated, diagnosing PUBS in chronic renal patients probably means an increased serum concentration of indoxyl sulfate, metabolite that is involved in the progression of both CKD and cardiovascular disease. Conclusion: Hence, in the context of our renal patients, perhaps PUBS is not as benign as supposed.

Test of exudates color hues for evaluating the physiological potential of coffee (Coffea arabica L.) seeds

Coffee seeds have slow and irregular germination, losing fast their viability during storage, and the standard germination test of these seeds requires at least 30 days. Besides, the results may not reflect the actual physiological quality of these seeds. The objective of this work was to develop a fast and practical test for evaluating the viability of coffee seeds, which is based on the interpretation of different color hues of exudates from seeds. Coffee seeds of the cultivar Catuai 44 from six lots were submitted to germination, accelerated aging, and electrical conductivity tests. In the exudates color hue test, coffee seeds without the parchment and the silvery pellicle (four replications of 10 seeds each) were distributed on top of paper towels moistened and then maintained into a germinator, at 25 ºC for 24, 48, 72, 96, and 120 h. Three classes of color hues were established: colorless, light color hue, and dark color hue, assigning the values of 0, 1, and 3, for each class, respectively. The proposed exudates color hue test can be recommended for the fast assessment of viability for coffee seeds. The most promising results were obtained for seeds with 12% moisture content, after imbibition periods of 72, 96, and 120 h; and with 30% moisture content, after imbibition periods of 72 and 120 h.

The train ride.

Una niña y su madre van en el tren desde la ciudad al campo para visitar a la abuela. Un texto que rima, establece el tono sobre todas las cosas que se pueden ver desde el tren. A la pregunta: qué veo, el cambio de página muestra un nuevo panorama: una yegua y su potro, un tractor de color rojo brillante, unos gansos, un globo de aire caliente, la respuesta y el estribillo :eso es lo que veo. Por fin la niña y su madre llegan a su destino. Recurso para la enseñanza de la lectura. Es el inicio de una reflexión sobre los textos y sus significados. Los niños pueden aprender a dividir una palabra en sus partes principales y crear nuevas palabras por analogía con las palabras que conocen, o para sugerir otras palabras. Para la lectura en grupos, individual o en parejas.

El lenguaje del absurdo en la obra de Lewis Carroll (Alice's Adventures in Wonderland and Through the Looking Glass. A Puffin book, Harmondsworth, 1962).

Se analiza la obra del autor inglés Lewis Carroll, en su obra titulada Alicia en el País de las Maravillas. Se considera que se trata no sólo de un maravilloso cuento para niños sino también de una obra maestra del lenguaje del absurdo. El libro describe las aventuras de una niña pequeña, Alicia. Para describir estas aventuras, Lewis Carroll usa un inglés sencillo, pero con un dominio tal de la lengua que no sólo consigue presentar situaciones absurdas, sino que logra no significar nada en absoluto. Se ponen como ejemplo varias situaciones y pasajes del libro. En definitiva el contenido es un puro absurdo, ya que en el poema las palabras, aunque estructuralmente en perfecto orden, son en gran parte creación suya, pero sin ningún significado. Aquí más que en ninguna otra ocasión, se revela la mente matemática del autor fuera de toda dimensión conocida. Una especie de lenguaje cifrado cuya clave sólo Carroll conocería. Lo esencial de este poema es esto precisamente: la invención de palabras que aunque no son propias del idioma inglés merecerían serlo. Finalmente, todo este lenguaje absurdo de la obra de Lewis Carroll es un perfecto ejemplo del sentimiento de fantasía que subyace en ambos cuentos. Leerlos no es solamente trasladarnos por unos momentos al mundo de lo maravilloso, sino también un ejercicio mental de primera categoría.

Orde Wingate and the British Army, 1922-1944

Major General Orde Wingate (1903–44) was the most controversial British military commander of the Second World War, due to his idiosynchratic leadership style, which led some to question his sanity, and his fiercely pro-Zionist stance. More than sixty years after his death he still splits opinion amongst soldiers, academics and writers.
