Three propolis samples were collected from different regions of Ecuador (Quito, Guayaquil and Cotacachi) and their methanolic extracts were prepared. Preliminary information supplied by TLC and NMR data, allowed us to define two main types of propolis: Cotacachi propoli sample (CPS), rich in flavonoids and Quito and Guayaquil samples (QPS and GPS) containing triterpenic alcohols and acetyl triterpenes as the main constituents. Two different approaches based on RP-HPLC preparative procedure and NMR structural determination (CPS) and GC–MS analysis (QPS and GPS) were successfully used for the chemical characterization of their major compounds. All three propolis extracts were able to inhibit Leishmania amazonensis growth but propolis sample rich in flavonoids was the most active (IC50 = 17.1 ± 1.7 μg/mL). In the literature this is the first study on propolis from Ecuador. © 2017

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: The convergence of factors leading to skate friction on some areas of skater's feet during trainings provoke nodular injuries. Objectives: To explore and to describe the imaging features of these circumscribed excrecences present in the skater's feet as consequence of sports overuse. Methods: A cross-sectional and descriptive study was conducted in 100 young no-sportsmen (controls) and in the 15 members of the Cuban Pre-Selection of speed Skating in April, 2009 (10 boys and 5 girls), all of them with more than 10 years of systematic sports practice. Then underwent a diagnostic echographic examination in the Institute of Sports Medicine to assess the condition of articular and periarticular structures of this area and data were processed by descriptive statistics. Results: There were demonstrated echographic distortions in 100% of assessed sportsmen, mainly due to: circumscribed dermic thickening (100%), tendonitis (33,3%) and exostosis bursata (20%), manifestations included in an affection identified by authors as «skater foot» whose external clinical expression is the presence of retrocalcaneal nodules, dorsal and/or foot medial region. Conclusions: The skater's foot may be a disease entity with an imaging support and is related to direct and systematic friction of skate, characteristic of this sport and that not only involve the teeth's skin but it may to interfere with treatment or competence due to its association with other injuries.

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.

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.

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.

Selective estrogen receptor modulators are classified as prohibited substances according to the list of forbidden substances in sports by the International Olympic Committee and the World Anti-doping Agency. Clomiphene (2-(4-(2-chloro-1,2-diphenylethenyl)phenoxy)-N,N-diethylethanamine) is mainly used for the treatment of infertility because it acts inducing the ovulation by direct stimulations of gonadotropic activity. Clomiphene citrate (50 mg per day for 5 days) was orally administered to one healthy female with infertility treatment. Urine samples were collected up to 1 week post-dose. A new metabolite using gas chromatography-mass spectrometry has been identified in addition to the hydroxyclomiphene previously reported. It has been proposed as hydroxymethoxyclomiphene. Monitorization of this metabolite have been proposed for doping control keeping in mind that the main metabolite hydroxyclomiphene is excreted relatively faster than hydroxymethoxyclomiphene from urine. On the other hand, significant changes on steroids profile after multiple doses were observed. The main variation was observed on absolute concentration of oestrogens and their ratios. © 2010 Sociedade Brasileira de Química.

The main goal of regenerative medicine is the development of new therapeutic methods useful for the replacement or repair of tissues or to promote its regeneration. These methods have achieved promising results in trauma and orthopedic disorders, mainly with the use of adult stem cells, but also with the use of platelets. The similarity of some of these disorders with those seen by sports doctors in athletes with minor injuries due to their training or sports participation, have allowed these procedures to develop good perspectives in the field of sports medicine, as it was considered that they may also be of great benefit in the treatment of sports injuries. Until recently, the intramuscular use of platelets was completely forbidden by sports authorities who considered this approach another source of doping. However, taking into account that platelet injections for therapeutic purposes do not violate the spirit of sport, in 2011 the prohibition was removed. Currently, the use of stem cells for therapeutic purposes is also not included in the prohibited list of World Anti-Doping Agency. Considering these decisions, an agreement was established between the Institutes of Sports Medicine and Hematology and Immunology, in order to take the first steps to implement these new methods in Sports Medicine.

Objective: To determine the size and direction of changes in anthropometric characteristics of Cuban volleyball players in the period 1970-2012. Material and method: Data on 560 high-standard volleyball players measured between 1967 and 2010 were collated to describe the evolution of body size and shape (somatotype) over the last 40 years. Where only summary statistics like arithmetical mean and standard deviation were presented, Monte Carlo simulation was used to generate pseudo-data. Individual data were available for 480 players.Trained and qualified anthropometries performed the measurements under standardized experimental conditions and in accordance with the procedures described by the International Biological Programme.These measurements included height, weight, breadths (biepycondylar femur and biepycondyar humerus), girths (arm flexed and calf) and skinfold thickness (triceps, subscapular, supraespinal and medial calf). Results: The rates of increase in stature were 0.18 and 0.22 cm. per year) for male and female respectively. The increase in stature (<1.0 cm per decade) was superior to the secular increase. Since 2010-2012, players have been less endomorphic (-0.01 and -0,02 units per decade) and less mesomorphic (-0.01 and -0.03 units per year), but much more mesomorphic (0.018 y 0.02 units per year) than before for male and female respectively. Conclusions: The somatotype of Cuban volleyball players has changed in the last ones 40 years toward a more linear and optimal figure, also there has been a secular decline in the endomorphy and mesomorphy.The observed changes may be a consequence of population secular trend or sport morphological adaptation.
