Chemical analysis confirmed the presence of (R,S) -2- and 3-methylbutan-1-ol in a 2:1 ratio; short chain acids (ethanoic to nonanoic acid); long chains acids decanoic to (Z)-9-octadecenoic acid; aliphatic aldehydes (hexanal to nonanal), benzaldehyde and dipropylsulphide from insects in copula. Electroantennographic studies conducted with a homologous series of aliphatic aldehydes on female and male T infestans showed that, for a given dose, EAG responses elicited from both sexes increased with increased chain length up to nonanal, after which EAG-activity declined. Attractiveness of non-acidic trace components identified in the volatiles were tested on male and female T. infestans, in an arena bioassay using a video tracking method. Aliphatic C6 to C10 aldehydes were tested: hexanal (1-100 microg) and heptanal (10 microg) were attractive to female T. infestans, high doses of octanal and nonanal (1-100 microg) were Unattractive to male and female T. infestans but low doses of nonanal (0.01-0.1 microg) were attractive to male T infestans. Benzaldehyde was highly attractive to female T. infestans at low doses (0.05- 0.1 microg). 3-methylbutan-1-ol was attractive to male T infestans at high dose (1,000 microg). (S) or (S,R) 2-methyl-butan-1-ol were attractive to males or females (1-1,000 microg). Blends of hexanal and benzaldehyde (20:1 and 40:1) showed an additive effect on attraction compared with hexanal alone, when tested on female T. infestans. The study has demonstrated the presence of a number of electrophysiologically and behaviorally active compounds in volatiles emitted by T. infestans in copula that may have a role in the postulated copulation pheromone.

With the development of magnetic resonance (MR) imaging, information could be obtained regarding TMJ disk position in asymptomatic joints also. The prevalence of asymptomatic disk displacement was 6% in a young population with a median age of 11 years 10 and increased to 34% in a population with a median age of 16 to 19 years. 8 In adults the prevalence ranged from 15 31% to 34%. 7,11 The high prevalence of disk displacement found in asymptomatic TMJs led to the suggestion that the condition might represent a congenital normal anatomic variant. Whether TMJ disk displacement is acquired solely or can also be congenital is still obscure. The purpose of the present prospective investigation, therefore, was to study the prevalence of the condition in infants and very young children.

En ella, el individuo se hace persona, desarrolla lo humano y se socializa para alcanzar los valores, las normas y las conductas que le permiten convivir de manera aceptable dentro de su grupo social. En su interior se forman los hábitos relacionados con la salud, se generan procesos que actúan como protectores de salud o desencadenantes de la enfermedad. La familia ha experimentado cambios muy significativos a lo largo de la historia, que han generado diversas formas de organización familiar. Es importante que las enfermeras reconozcan las repercusiones de la composición y estructura en la salud familiar, pues términos como familia nuclear, familia monoparental, de madre soltera, familia extendida, o familia homosexual, se refieren a personas viviendo en el mismo espacio familiar. Esta diversidad de familias tan heterogéneas, en cuanto a su naturaleza y a su desarrollo cotidiano, hace necesario que la Enfermera Familiar las considere al proporcionar atención a la familia, englobando los aspectos de su experiencia, como: su historia, su progreso y su estado actual, utilizando de forma prioritaria las estrategias de atención primaria.
