Background & Aim: Thyme is common named Thymus vulgaris L. belongs to Lamiaceae family. Thyme is a most important medicinal plant that was used in pharmaceutical, food, cosmetics hygienic industries in most of developed countries. Experimental: Determine optimum of harvest time this plant was done in a random block design with three replications was conducted in field Islamic...

The genetic control of the switch between seasonal and perpetual flowering has been deciphered in various perennial species. However, little is known about the genetic control of the dynamics of perpetual flowering, which changes abruptly at well-defined time instants during the growing season. Here, we characterize the perpetual flowering pattern and identify new genetic controls of this patte...

Plants have evolved many systems to sense their environment and to modify their growth and development accordingly. One example is vernalization, the process by which flowering is promoted as plants sense exposure to the cold temperatures of winter. A requirement for vernalization is an adaptive trait that helps prevent flowering before winter and permits flowering in the favorable conditions o...

The photoperiodic response in Arabidopsis thaliana requires the precise regulation of CONSTANS (CO) expression in relation to the light period during the day. In short days (SDs) levels of CO expression are normally low during the light period, and this results in delayed flowering compared with long days (LDs) when CO expression rises to high levels before the end of the light period. We ident...

Seagrasses form extensive meadows in shallow coastal waters and are among the world's most productive ecosystems. Seagrasses can produce both clonally and sexually, and flowering has long been considered infrequent, but important for maintaining genetically diverse stands. Here we investigate the molecular mechanisms involved in flowering of the seagrass Posidonia oceanica, an iconic species en...

The objective of this study was to analyse the phenological events in the herbaceous and subshrub layer in relation to rainfall and the dispersion syndromes of the species at a Campo Sujo community in the Agua Limpa Farm (FAL), Brasília-DF. Campo Sujo is a grassland Savannah with a few scattered shrubs and small trees. The climate is Aw by Köppen classification with a mean annual precipitation ...

Aortic valve replacement (AVR) is currently the treatment of choice in patients with symptomatic aortic stenosis, but transcatheter off-pump aortic valve implantation is a novel and emerging technique, which might be performed more frequently in the near future and may be a less invasive alternative to conventional AVR in selected high-risk patients. Up to date, the preoperative patient selecti...

INTRODUCTION The use of hospital care increases significantly with age. Older people coming to the emergency department have three to seven times higher rates of hospitalization than younger people. Hospitalization can lead to loss of independence and also need for long-term care at discharge. METHODS A prospective observational non-randomized study of elderly patients admitted to the Departm...

BACKGROUND Pregnancy loss before 6 weeks' gestation is common, but little has been reported about the associated bleeding. We compared women's bleeding following a pregnancy loss before 6 weeks' gestation with their typical menstruation. METHODS Women provided daily urine samples while trying to become pregnant and recorded the number of pads and tampons used each day. Thirty-six women had co...
