clinical reproductive centers produce large amounts of surplus poor-quality embryos annually, how to maximize the use of these embryos, and which of them have the potential to develop into blastocyst stage and influencing factors were lack of systematic research. objective: to investigate the fate of surplus poor-quality embryos which were cultured to obtain blastocyst, determine the factors wh...

Genetic analyses, particularly in Arabidopsis, have led to the identification of mutants that define different steps of ovule ontogeny, pollen stigma interaction, pollen tube growth, and fertilization. Isolation of the genes defined by these mutations promises to lead to a molecular understanding of these processes. Mutants have also been obtained in which processes that are normally triggered ...

diadema setosum (leske, 1778), is one of the common echinoids widely distributed in the indo-west pacific ocean, where it occurs from the red sea, persian gulf and the east coast of africa to japan, australia and malaysia. to investigate the developmental basis of morphological changes in embryos and larvae, we documented the ontogeny of d. setosum in a controlled laboratory condition at the in...

The article explores cross-innovation between CCIs and SMEs. To enable such innovation, the DIVA project developed a set of tools methods, based on an analysis field-specific stakeholder requirements. By looking at specific cases interaction designers artists one side business firms other, also leaning Cross Innovation considering wide range secondary research, captures both existing mechanisms...

Background: Currently, ARTs are of indispensable importance in treatment of human infertility. While ARTs are considered to be safe, some studies suggest that ARTs manipulations may perturb the epigenetic information and subsequently the health of the offspring. To examine these events further, this study was conducted to assess the effect of superovulation, in vitro culture and vitrification o...

ABSTRACT The objective of this study was to evaluate the physiological indices sour passion fruit under brackish water irrigation strategies and potassium fertilization. carried out field conditions in São Domingos, PB, Brazil, using a randomized block design 6 × 2 factorial scheme, with treatments consisting six (irrigation moderately saline (1.3 dS m-1) throughout crop cycle - WS; high-salini...

background: caffeine increases the camp production that stimulates spermatozoa movement. caffeine is also used for induction of in vitro acrosome reaction in mammalian spermatozoa, an important step in achieving fertilization. objective: the aim of this study was to assess the effect of caffeine on sperm's motility, vitality and laboratory fertilization rates in mouse in two t6 and m16 media. m...
