Effect of plant growth regulators on plant regeneration of Dioscorea remotiflora (Kunth) through nodal explants

Abstract

Objective: To measure the effect on blood pressure readings when a standard cuff is used on patients with arms of a large circumference, and to determine the frequency of arms of a large circumference. Subjects: Blood pressures were taken in 120 subjects with an arm circumference greater than 33 cm. Also, the arm circumference was determined in 244 patients from a family health unit, and in 216 patients from a hypertension clinic. Method: A mercury sphygmomanometer and two different cuff sizes were used in a random sequence; therefore, 60 patients' blood pressure were first measured with a large cuff, followed by a standard cuff; the opposite sequence was then applied for another 60 patients. With the obtained values and using a regression analysis, the difference in blood pressure overestimation was calculated. Arm circumference measurement percentages were used to determine the frequency of arms of a large circumference. Results: Both systolic and diastolic blood pressures were significantly greater when the standard cuff was used. For every 5 cm increase in arm circumference, starting at 35 cm, a 2-5 mmHg increase in systolic blood pressure, and a 1-3 mmHg increase in diastolic blood pressure was observed. The prevalence of arms with a large circumference in the family medicine unit and hypertension clinic was 42% and 41.8%, respectively. Conclusions: There is an overestimation of blood pressure when a standard cuff is used in obese subjects. The high prevalence of these individuals in our environment, both in the hypertensive and normotensive population, makes it necessary to have on hand different sizes of cuffs for taking blood pressure in order to avoid incorrect decisions.

Se han registrado, al menos, 30 especies de triatominos vectores, la mayoría con hábitos domásticos y tendencia a invadir las viviendas humanas. Objetivo. Evaluar la utilidad de gallineros en la vigilancia de la presencia de triatominos peridomásticos y conocer su situación en el área de estudio. Materiales y métodos. Se realizó un estudio de campo, experimental, longitudinal, por un año. Se instalaron 50 gallineros en 50 viviendas de tres localidades del municipio de Teocuitatlán de Corona, en el estado de Jalisco, México. Se inspeccionaron los gallineros y las viviendas para saber si aquíllos podían detectar la presencia de triatominos, para estimar la situación vectorial en el área. Resultados. Se recolectaron significativamente (p<0,05) más especímenes de Meccus longipennis (93%) que de Triatoma barberi (7%). Aproximadamente, un tercio (31,3%) de los especímenes de M. longipennis y ninguno de T. barberi se recolectó en los gallineros. M. longipennis tuvo un porcentaje de infección por Trypanosoma cruzi de 25,7%, y T. barberi, de 53,2%. Los meses de primavera y verano fueron en los que se recolectaron más ejemplares de triatominos. Conclusiones. Los gallineros se consideran una herramienta útil para detectar la presencia de ejemplares de M. longipennis, aunque no funcionaron para T. barberi. Se confirma la importancia de M. longipennis y se establece el posible rol primario de T. barberi como vector en el área de estudio.",,,,,,,,"0120-4157","http://hdl.handle.net/20.500.12104/38847",,,"Spanish",,"Instituto Nacional de Salud",,"1",,"Biomédica",,"140

A field experiment was carried out in two locations of the Mexican Highlands (Montecillo and Chapingo) to evaluate the response of two wheat cultivars ('Seri M82' and 'Rebeca F2000') to four inoculum rates (106,8,10 cfu mL-1, plus a control without inoculum). Disease incidence and severity, seed yield, seed number and seed size were measured. At flowering and seed physiological maturity, aerial biomass production and distribution of main stem, secondary stems and total plant were recorded. Source-sink relationships during the grain filling period were estimated. Higher values of disease incidence and severity were observed at Chapingo; the same traits were also greater in 'Seri' than in 'Rebeca' at both sites (p &lt; 0.05). Seed yield, seed number and seed size of 'Rebeca' were higher (p &lt; 0.05) than that of 'Seri'. The pathogen reduced (p &lt; 0.05) plant height, seed yield, seed yield components, and biomass production of most organs of main and secondary stems. The magnitude of the reductions was similar in both cultivars at both sites. The effect of the bacteria at each location was higher (p &lt; 0.05) at greater doses affecting seed number more than seed weight. Stems prevailed as sink organs, while laminae, sheaths, spikes, and other vegetative parts predominated as source organs. Plant disease records should complement crop physiological variables to evaluate and to explain bacterial disease effects.",,,,,,,,,"http://hdl.handle.net/20.500.12104/40993","http://www.scopus.com/inward/record.url?eid=2-s2.0-82755181686&partnerID=40&md5=144fd1e533e766aa5c6e79e24f06ecbc",,,,,,"4",,"Spanish Journal of Agricultural Research",,"1287

Cruz-Sosa, F.",,"2012",,"Dioscorea remotiflora (Kunth) is an important wild plant that produces tuberous roots used as a source of food in the Western part of Mexico. Lack of planting material and inefficiency of traditional methods of propagation are the main constraints for implementing large-scale cultivation. In contrast, tissue culture techniques allow increasing multiplication and rapid production of plant material. In this regard, leaves or nodal segments were incubated on MS, B5 and WPM culture media with different PGRs in order to obtain an efficient micropropagation protocol. Leaves explants were unable to inducing shoots or callus. However, nodal segments produced axillary shoots and/or callus in all culture media. MS containing 2. 33 ?M KIN was the most suitable to inducing shoots; an average of 6. 6 shoots per segment for 100 % explants was obtained, which displayed also the greater number of nodes (5. 0) and leaves (7. 9) per segment. A decrease on shoot proliferation was observed combining BA or KIN with 2,4-D or NAA. However, small brownish callus were induced on 100 % of segments using 2. 33 ?M KIN with 5. 37 ?M 2,4-D or 9. 30 ?M KIN plus 2. 69 ?M NAA. In contrast, by adding 2. 69 ?M NAA, 66. 4 % of the nodal segments formed shoots and produced also yellowish friable callus on the base of the shoots. Shoots were easily rooted with 8. 28 ?M IBA (96. 9 %), displaying the greatest root and shoot biomass, but maximum number of tuberous roots, and root or tuberous root biomass was produced increasing IBA (20. 7 ?M).
