The Maternal Mortality Ratio (MMR) is an indicator that analyses the life conditions and care given to pregnant women, and indicates whether the constitutional rights related to life and health are being complied with. This study shows losses of lives among adolescent women associated with pregnancy, childbirth and the puerperal period, in the state of Santa Catarina between 1994 and 2005. It is an exploratory study of a quantitative nature. There were 72 maternal deaths in adolescents, 67% had a direct obstetric cause, 23% had an indirect obstetric cause and about 9% were classified as accidental or incidental. The Maternal Mortality Ratio in adolescents was high and most could have been prevented and its causes controlled. The identified situation shows an absence of quality health care. To reduce these deaths it is central that nursing action be combined with other professionals and other organized sectors of society.

Genomic DNA methylation patterns play a crucial role in the developmental processes of plants and mammals. In this study, we aimed to investigate the significant effects of epigenetic mechanisms on the development of soybean seedlings and metabolic pathways. Our analyses show that 5-azaC-treatment affects radicle development from two Days After Imbibition (DAI), as well as both shoot and root development.

In plant tissue culture, differences in endogenous levels of species-specific plant growth regulators (PGRs) may explain differences in regenerative capacity. In the case of polyamines (PAs), their dynamics and distribution may vary between species, genotypes, tissues, and developmental pathways, such as sexual reproduction and apomixis. In this study, for the first time, we aimed to assess the impact of varying endogenous PAs levels in seeds from distinct reproductive modes in Miconia spp.

Article Synopsis
- Sex segregation in plant propagation raises production costs, making in vitro clonal techniques particularly useful for hermaphroditic plants.
- The study analyzed the proteome of calli from zygotic embryos treated with a plant growth hormone to understand key proteins involved in callus formation over 21 days.
- Results showed distinct patterns in protein accumulation, with certain proteins related to seed maturation decreasing while others tied to metabolism and hormone response increased, highlighting their roles in establishing embryogenic competence.
