RESUMEN

INTRODUCTION@#Salba-chia (Salvia hispanica L.) is a popular functional food containing high levels of protein, total dietary fiber, and is an excellent source of α-linolenic acid. Chia seeds significantly decreases weight, suppresses appetite, and has a potential benefit in the management of Type 2 diabetes mellitus (T2DM). This study aimed to determine the effectiveness of chia seeds as an adjuvant treatment for T2DM.@*METHODS@#Randomized controlled trials from 1990 onwards involving Type 2 diabetic patients given chia seed were included. PubMed, Cochrane, ClinicalKey, Google Scholar, and Hinari were searched systematically using MeSH terms “chia”, “Salvia hispanica”, “dietary supplement”, and “diabetes”. The quality of trials was assessed using the Cochrane Collaboration tool. Data on the study design, blinding status, characteristics of participants, medications taken by participants, chia seed intervention, comparator, duration of intake, and interval of assessment were extracted. The percent change of outcome from baseline was compared between the chia and control groups.@*RESULTS@#Four randomized trials with a total of 213 diabetic patients were enrolled in the treatment group using ground salba-chia or the control group using bran. The supplementation of chia resulted in a statistically significant decrease in fasting glucose (-2.90 mmol/L; 95% CI, -3.08, -2.72; p < 0.001), waist circumference (-2.49 cm; 95% CI -2.81, -2.17; p < 0.001), total cholesterol (-2.72 mmol/L; 95% CI -3.68, -1.74; p < 0.001), HDL (-3.69 mmol/L; 95% CI -3.95, -3.42; p < 0.001), LDL (-3.22 mmol/L; 95% CI -4.08, -2.36; p < 0.001); and an increase adiponectin levels (6.50 mg/L; 95% CI 6.25, 6.25; p < 0.001).@*CONCLUSION@#Intake of chia seeds resulted in a statistically significant decrease in fasting blood glucose, waist circumference, total cholesterol levels, HDL and LDL cholesterol levels, and increased adiponectin. Chia seeds are generally safer and have lesser side effects compared to the placebo. Chia is effective as adjunctive treatment for Type 2 diabetic patients.

RESUMEN

In order to know the environmental behaviour of toxic pollutants it is fundamental to understand the role of chemical components of a material on sorption of such pollutants. In this study, the sorption of a mix of polycyclic aromatic hydrocarbons [PAHs] by cork fractions [i.e. raw cork [CF], free extractive cork [FEF] and nonsaponifiable [DESF]] has been investigated to better understand the role of biopolymers and extractable fraction of cork on their sorption behaviour. All samples were analyzed through elemental analysis and were examined using Fourier transform infrared spectroscopy. After removing the extractable fraction and the suberin from the cork, the sorption capacities [K[oc]] of FEF and DESF exhibited mean reductions of 70% and 30% respectively. In addition, the sorption results of three pairs of cork samples with different chemical content confirm that the extractable fraction serves as the major sorption medium for PAHs. Considering only low molecular weight PAHs positive correlations between K[oc] with K[ow] [R[2]=0.70] and F number [R[2]=0.65] were found, showing that these parameters are involved in this adsorption process
