Título:  Progestogen supplementation during superovulation leads to higher embryo viability and TGFB1 gene expression in sheep.

Conteúdo:  Abstract: This study aimed to compare the effect of the administration of either medroxyprogesterone acetate (MPA) or progesterone (P4) in superovulation (SOV) treatments applied during the first follicular wave on follicular development, embryo yield, and the expression of genes related to pluripotency maintenance, differentiation of the trophectoderm, cell growth and differentiation, apoptosis and energy metabolism in sheep embryos. The estrous cycle of 36 multiparous ewes was synchronized with a short protocol, and the animals were randomly allocated to three groups. At the beginning of SOV, 12 ewes per treatment received an intravaginal sponge impregnated with 60 mg of MPA (TMPA), or an intravaginal device containing 0.33 g of P4 (TP4), or received no progestogen treatment (CON). The device was kept until the fifth dose of FSH. Ewes were mated with five fertile rams. Gene expression was performed by RT-qPCR using grade I and II blastocysts. The numbers of corpora lutea, total structures and viable embryos recovered per ewe were similar (P > 0.05) among groups. However, the viability rate was higher in TP4 (71.9 ± 16.3%) compared to CON (24.4 ± 16.8%; P = 0.01) and similar to TMPA (49.9 ± 16.3%; P = 0.2). Similarly, when compared with CON, treatment with P4 or MPA positively regulated the TGFB1 transcript involved in cell proliferation and differentiation (P = 0.01 and P = 0.03, respectively). In conclusion, supplementation with P4 during the first follicular wave of the ... Mostrar Tudo

Título:  Cultivation of water lettuce with different doses of salinity.
Ano de publicação:  2023

Conteúdo:  With the increase in pollution of water bodies, there is a need to look for decontamination alternatives. Thus, there is a need for more studies aimed at removing these pollutants, with phytoremediation emerging as an alternative, using accumulator plants such as water lettuce (Pistia stratiotes), which is a macrophyte found in fresh surface waters with a high amount of organic matter. This study sought to assess how some growth parameters and the chlorophyll concentration of water lettuce might be affected when grown in different doses of salt. To this end, an experiment was carried out in which the plants were grown for 14 days in pots containing different doses of NaCl: T1: Control (0 g/L); T2: water + 2 g/L of a nutrient solution composed of Nitrogen, Phosphorus and Potassium (15-30-15); T3: 1% of the dose of sea salt diluted in water (0.35 g/L); T4: 5% (1.75 g/L) and T5: 10% (3.5 g/L), each with 5 replicates. Leaf number, plant neck diameter and chlorophyll concentration were analyzed. The number of leaves increased in all treatments, while the diameter decreased in the presence of the nutrient solution, and in the doses of 1.75 and 3.5 g/L. The chlorophyll concentration was higher in the nutrient solution and at the 3.5 g/L dose. This indicates that small doses of salt do not affect plant growth.
