Introduction: Vernonanthura patens (Kunth) H. Rob. is a species that grows wild in Ecuador. Few chemical and biological studies have been conducted on this species, and none of them deal with lipid fractions. Objectives: study the fractions of lipid compounds present in the leaves, stems and flowers of the species. Methods: the plant was collected in its adult stage, during the flowering season. Plant organs were oven dried separately, ground to 2 mm particle size, and extracted by maceration with ethanol. The concentrated ethanolic extracts were separated by column chromatography. Lipid fractions were separated with hexane, and then saponified and analyzed by coupled gas chromatography mass spectrometry. Results: identification of the fatty acids and unsaponifiable compounds present in the organs studied revealed some differences in their composition. Conclusions: 29 fatty acids and 8 unsaponifiable compounds were identified in the plant organs studied. Source

In this study, on the basis of the information supplied by NMR and HPLC-PDA data, we reported a quali-quantitative GC-MS study of 19 yellow Cuban propolis (YCP) samples collected in different regions of Cuba. The profiles of YCP samples allowed us to define two main types of YCP directly related to their secondary metabolite classes: type A, rich in triterpenic alcohols and with the presence of polymethoxylated flavonoids as minor constituents, and type B, containing acetyl triterpenes as the main constituents. For the first time, triterpenoids belonging to oleanane, lupane, ursane, and lanostane skeletons were reported as major compounds in propolis. Also, the presence of polymethoxylated flavones or flavanones was found for the first time in propolis. © 2010 American Chemical Society. Source

Background: Some studies have found that, over the years, in addition to increasing body fat is redistributed unfavorable to the health of the elderly way, the amount of adipose tissue in the center of the body, which can be an important risk factor for the development of chronic diseases such as Diabetes Mellitus. The target was the nutritional status of centenarians assessed diabetic and not diabetic and changes in anthropometric indicators were explored. Methods: An analytical study of cases and randomly selected controls were performed. A total of 70 centenarians Havana, 35 diabetic and 35 nondiabetic controls, which were calculated the body mass index, arm and leg were studied. Absolute frequencies and percentages as well as mean standard deviation for quantitative variables were calculated. Results: In both groups predominated women compared to men, were distributed by age between 100 and 104 years, both diabetics ancient and non-diabetics had, in 2010, a normal nutritional status according to BMI and brachial circumference, but not for the calf circumference showed malnutrition in both groups. Conclusions: Nutritional status of diabetic and nondiabetic centenarian was acceptable in terms of body mass index and arm circumference, but not in terms of calf circumference where malnutrition was evident.

Introduction: At present, the relationship between diet, nutrition and HIV infection has been demonstrated. The scientific community recognizes that knowledge and nutritional care can help maintain health and reduce the effects of the infection. Objective: To assess the nutritional status of people living with HIV-AIDS treated in out-patient clinics of Plaza County. Subjects and Methods: A descriptive cross-sectional study in 87 people infected with HIV (66 males and 21 females). Fifty four asymptomatic infected people and 33 AIDS patients were studied. Nutritional assessment consisted of anthropometric measurements: weight, height, triceps skinfold and arm circumference to calculate the body mass index, and fat and arm muscle area; dietary assessment with frequency questionnaires and food consumption by food groups; measurement of biochemical parameters: hemoglobin, triglycerides, blood sugar and cholesterol. Values were compared with the Student t test and Spearman correlation. Results: The largest group was asymptomatic male between 30-49 years. Few cases of anemia were detected. Hyper triglyceridemia and discrete reductions in fat reserves were predominant. Half of people with AIDS presented bad eating habits. More than half presented sufficient level of knowledge and attitude. Conclusion: It is necessary to increase the attitude of these patients in relation to the care of their nutrition. © 2015, Sociedad Chilena de Nutricion Bromatologia y Toxilogica.

The degenerative joint disease, also known as osteoarthrosis affects to 10% of elderlies aged 60. It is mainly characterized by pain in the involved joint, crepitation, morning stiff and a progressive limitation of movement of that joint leading to a partial or total wear of articular cartilage. The treatment of the knee osteoarthrosis is a great challenge. The recent advances in use of regenerative medicine suggest that adult stem cells could represent a promisor alternative in the treatment of this entity. In a female patient aged 61 presenting with knee osteoarthrosis authors placed a percutaneous implant of autologous mononuclear cells mobilized to peripheral blood by granulocyte colony-stimulating factor achieving a fast clinical and radiological improvement. This result suggests that the procedure used is a feasible, simple, safe and less expensive method for treatment of articular degenerative lesions. Source
