Plant tissue culture allows the clonal propagation of Coffea canephora on a large scale through somatic embryogenesis. The aim of this study was to optimize the conditions for the induction of somatic embryogenesisin leaves of the Robusta variety. The physiological stage of the leaves – drain or source; the use of the surrounding area ofprimary or secondary veins; and the position of the explants – abaxial or adaxial surface in contact with the culture medium were evaluated.

Clonal propagation of Coffea canephora varieties is feasible through somatic embryogenesis. The aim of this study was to evaluate the induction of somatic embryos from leaves of C. canephora, Robusta and Conilon varieties, in relation to different concentrations of three growth regulators. The explants were inoculated in a MS culture medium with 2iP (isopentanyladenine), IBA (indolebutyric acid) and BA (6-benzylaminopurine), in factorial combinations, at concentrations of 1.0; 2.0; 3.0; 4.0 and 5.0 mg L-1.

As a result of aging, the elderly become more prone to pathological developments, increasing drug consumption. This increases the possibility of errors related to drugs, such as interactions and adverse reactions. The pharmacotherapeutic follow-up has become indispensable in the care of the polymedicated elderly.

Escherichia coli is a pathogenic microorganism that can be introduced into the human body through contaminated water and food, causing gastrointestinal or urinary tract infections, being a bioindicator of water quality and risk to human health. The aim of the present research was to analyze the water quality of streams located in the Itaqui-Bacanga district using bacteriological indicators and establish a correlation between cause and effect considering the housing conditions, sanitation, healthcare aspects of local residents.

Dentre os fatores ambientais que influenciam a germinação do melão destaca-se a temperatura, uma vez que ela afeta a velocidade e a porcentagem de germinação e os processos de hidratação e mobilização de reservas. Este trabalho teve por objetivo avaliar a influência da temperatura sobre a porcentagem de germinação, o índice de velocidade de germinação e o tempo médio de germinação de sementes de meloeiro. O experimento foi realizado no laboratório de Biologia Vegetal do Instituto Federal do Sertão Pernambucano - Campus Zona Rural.
