Objective: to determine the relationship between Ret-He with different categories according to hemoglobin concentration in candidates for blood donation. Methods: A cross-sectional study was carried out based on the review of 227 medical records of candidates to donate blood during the month of December 2021 in the Blood Bank and Hemotherapy Service of the Cayetano Heredia Hospital. They were categorized into 3 groups according to hemoglobin levels: Group 1: ≥12.5 g/ dl (females) - ≥13.5 g/dl (males). Group 2: 12 g/dl ≥ females <12.5 g/dl and 13 g/dl ≥ males<13.5 g/dl. Group 3: <12 g/dl (females) - <13 g/dl (males). Hematocrit, hemoglobin, VCM, HCM, CHCM and Ret-He data were collected. For the bivariate analysis, analysis of variance (ANOVA) was used and a significance level of 5% was considered. Results: The median Ret-He was higher in group 1 than in group 2 (33.5 v...

El objetivo del presente estudio de investigación fue determinar la relación entre autoestima y agresión en estudiantes de una Institución Educativa Pública del nivel Secundario de la ciudad de Juliaca. Se utilizó un diseño no experimental, de corte transversal de tipo descriptivo correlacional; la población estuvo conformada por 798 estudiantes de ambos géneros, se contó con una muestra de 195 estudiantes, se utilizó el método de muestreo probabilístico estratificado. Para la medición de variables se utilizó los instrumentos; el Inventario de Autoestima de Coopersmith y el Cuestionario de agresión de Buss y Perry. Los resultados indican que existe una relación inversa moderada (rho = -,467); entre la autoestima y agresión, así mismo esta relación es significativa puesto que el valor de p = ,000 es menor al 0,05. Es decir que cuanto mayor sea el desarrollo de la autoe...

The colors of native pigmented potatoes were extracted, purified and the anthocyanin spectra identified by FTIR and UV Visible in this solution. In the extract, the effect caused by different cooking processes (boiled, fried and microwaved) of native pigmented potatoes was quantified for total anthocyanins (CAT) and total polyphenols (PFT) before and after each process. The content of (CAT) in the native red potato (PST) and purple potato (PWQ) was 59.21 and 19.35 (mg cyanidin 3 glucoside / 100 g) respectively and once processed the potato (PST) decreases its (CAT) to 4.63 (mg cyanidin 3-glucoside / 100g) in the process of cooking by microwave oven, like potato (PWQ) at 1.31 (mg cyanidin 3-glucoside / 100g) in frying. The composition of (PFT) in potato (PST) and (PWQ) of 179.51 and 87.92 (mg gallic acid / 100g) respectively and after processing, are 125.27 (mg gallic acid / 100g) in the ...

Therefore in this research the shelf life time of vacuum-packed cured guinea pig meat using different concentrations of sodium chloride was determined and the effects produced sodium chloride on the proximal chemical composition of guinea pig meat cured were evaluated, giving a longer shelf life time, the analytical methods used were: pH, TBA value, water activity, microbiological tests: aerobic mesophilic count, Staphylococcus aureus, Salmonella sp. and Escherichia coli. For proximal chemical evaluation were performed tests of % moisture, % ash, % protein and% fat, making a comparison between the 1% concentration of sodium chloride with a standard sample (C0%). Based on the results it was observed that the concentration of sodium chloride 1% provided greater shelf life 12 days compared to concentrations of 3% and 5% sodium chloride they showed lifetime of 10 and 8 da...

The objective was to evaluate the oxidative stability of soybean oil with the addition of antioxidant of isaño (Tropaeolum tuberosum Ruiz & Pavón) and TBHQ during potato frying, analyzed at 0, 1,5, 2,5 and 3,5 hours At 180 ° C + 10 ° C, with frying intervals of potatoes every 30 minutes, performing eight frying events. To evaluate, peroxide, acidity, dienes and trienes were tested for indices. During the frying, soybean oil samples with the addition of extract Isaño showed less formation of dimer and triers compared to the sample of soybean oil with TBHQ, indicating greater protective effect on the oxidative stability of soybean oil during frying, without However, this sample showed a higher correlation compared to the oil samples with the addition of Isano extract, due to the presence of residues of sugars in said extracts. The peroxide index and free fatty acid percentag...
