Rifampin and tetracycline treatments were associated with a significantly lower proportion of ticks that hatched, a lower proportion of viable larvae among total larvae that hatched, and lower number of viable larvae per tick.
As atomoxetine may offer a viable alternative for a substantial proportion of ADHD children who were ineligible for MPH due to a history of stimulant treatment failure and/or co-morbidities contra-indicated to simulants, atomoxetine treatment for these children was also compared to 'no medication' since they would usually have no alternative medication options otherwise.
Spermatozoa diluted to lower cell concentrations had a higher proportion of viable cells that were acrosome reacted (P < 0.001).
Spermatozoa diluted to 10 × 106 sperm/ml and stored at ambient temperature had a higher proportion of viable spermatozoa (P < 0.01) and were less susceptible to osmotic stress (P < 0.01) than sperm diluted to 60 × 106 sperm/ml.
This significant reduction in the amount of antigen needed to induce an immune response is most likely the result of directly targeting vaccine to a higher proportion of viable APCs in skin (e.g. achieved targeting of several thousands of Langerhans cells and dermal APCs per 0.32 cm2 of targeted skin) than current delivery methods.
Male crickets, Teleogryllus oceanicus, are capable of making adjustments to the quality of their sperm in response to both the risk and intensity of sperm competition; when males perceive the presence of a potential rival they produce ejaculates with a greater proportion of viable sperm than when isolated from other males [10].
In particular, studies on sperm viability are almost entirely lacking; though at least in insects, sperm viability has been shown to influence competitive fertilization success [40], and polyandrous species have been shown to have a greater proportion of viable sperm available for ejaculates relative to monadrous species [41].
In addition to viable cells, a large proportion of neoplasms contained areas of cornification and necrosis.
Thus if a parent cell contains duplicates it will have a higher proportion of viable daughter cells.
Among viable cells, a large proportion of RPS19 silenced cells were in G0/G1 phase, whereas the percentage of cells in G2/M phase decreased about 1.7 fold compared to SCR control (Fig. 2C).
