    Abstract This study aimed to evaluate the tannin content in the bark of five pine species from a forest harvesting area of the Ixtlán de Juárez community, Oaxaca, México. The species studied were Pinus patula, Pinus ayacahuite, Pinus rudis, Pinus douglasiana, Pinus pseudostrobus. The bark samples were subjected to a drying, grinding, and sieving process. These compounds were extracted using two methods: by constant reflux with ethanol for three hours or in a water bath with distilled water for two hours. The percentage of total extract, Stiasny number, and condensed tannins were quantified. The quantitative number of condensed tannins present in the bark for each of the five species studied ranged from 0.65% to 5.14% for the ethanolic extracts and 0.14% to 1.46% for the aqueous extracts. Analysis by Fourier transform infrared spectroscopy (FTIR) identified polyphenolic compounds and functional groups characteristic of tannins. Analysis by scanning electron microscopy (SEM) and X-ray dispersive spectroscopy (EDX) provided the elemental analysis and chemical composition of the tannin extracts, respectively, finding trace elements of silver, cadmium, phosphorus, iodine, and sulfur, which are minerals present in the soil, meaning that through processes of micronutrient absorption, these can interact with the tannins or polyphenols in the barks of the tree species being studied. The results indicate that the bark of P. patula and P. ayacahuite have a higher concentration of condensed tannins, 5.14% and 4.71%, respectively, in the ethanol extraction, and may be susceptible to exploitation due to the amount of bark generated in forestry activities.

    Abstract To present a systematic review of published studies in databases such as PUBMED, REDALYC, SCIELO, DIALNET, SCOPUS, EBSCO and CONRICYT related to the role-played by the components present in the vegetable oil of grape seed (Vitis vinífera) and the prevention or delay in the onset or progression of neurodegenerative diseases. The analysis of the research revealed that neurodegenerative diseases causes alterations in consciousness or in the nervous system leading to severe damage in neuronal cells, these pathologies are considered gradual and progressive. Various syndromes manifest the degenerative diseases of the nervous system; in some of them the predominant symptom is the progressive dementia. Among the components of the diet that in numerous epidemiological studies have shown an inverse association are vitamins, minerals, carotenoids, polyunsaturated fatty acids and polyphenols, the latter being the ones addressed in this document. There is an important evidence that a nutritional support based on polyunsaturated fatty acids and antioxidants can be applied to subjects with a history of neurodegenerative conditions in order to act as neuroprotectors. This requires the determination of the nutritional benefits of these nutrients or of nutraceuticals for the health of this group of patients.

    Abstract Glycosylation is a post-translational modification that affects the stability, structure, antigenicity and charge of proteins. In the immune system, glycosylation is involved in the regulation of ligand-receptor interactions, such as in B-cell and T-cell activating receptors. Alterations in glycosylation have been described in several autoimmune diseases, such as systemic lupus erythematosus (SLE), in which alterations have been found mainly in the glycosylation of B lymphocytes, T lymphocytes and immunoglobulins. In immunoglobulin G of lupus patients, a decrease in galactosylation, sialylation, and nucleotide fucose, as well as an increase in the

    Title translation Increasing consumption of dietary fiber complementary to the treatment of metabolic syndrome.
    Abstract Introduction: the amount of fiber ingested in Latin American countries is lower (10-20 g/d) than recommended (35 g/d). An increase isrecommended for patients with metabolic syndrome (MS) to reduce cardiovascular risk, as well as to prevent obesity and other complications.
    Objective: to evaluate whether increased dietary fiber consumption complements MS treatment and improves clinical and laboratory parameters in subjects at the San Martín Mexicapam "La Joya" Health Center, Oaxaca (Mexico).
    Methods: an analytical-longitudinal study was carried out from January to April 2017, to evaluate nutritional status before and after intervention with dietary fiber and to measure cholesterol levels, triglycerides and fasting blood glucose. An increase of 15 g of fiber (fruits-vegetables and/or oat bran and/or wheat bran) was indicated in the usual diet over eight weeks.
    Results: the sample consisted of 30 participants from the Mutual Aid Group diagnosed with MS, with an average age of 37.26 years, starting from a body mass index (BMI) of 30.75 kg/cm2 and levels of fasting glycemia at 153.87 mg/dl, triglycerides at 209.67 mg/dl, and cholesterol at 213.81 mg/dl. Following the intervention, a statistically significant difference (p < 0.05) was obtained with a BMI of 29.7 kg/cm2, fasting glycemia at 127.77 mg/dl, triglycerides at 179.71 mg/dl and cholesterol at 207.13 mg/dl.
    Conclusion: a reduction in the results for the parameters tested in patients of MS is improved by a greater consumption of dietary fiber, such as oat bran. However, additional studies are required to generate clearer recommendations.
