Key to deciphering the history and origin of the radar-bright deposits is an estimate of the volume of radar-bright material that in turn requires a measure of the average thickness of the deposits. In this study we investigate changes in topography across radar-bright deposits hosted in flat-floored, complex craters using individual edited Mercury Laser Altimeter (MLA) tracks. We compare the difference in heights of radar-bright regions and non-radar-bright regions of the crater floor and the difference of similarly sized and located regions in non-radar-bright craters and show that the two populations cannot be distinguished. The similarity of topography in these two sets of craters allows an upper limit of 15 m to be placed on the thickness of the radar-bright deposits.}, journal={ICARUS}, author={Susorney, Hannah C.

Two methods for activation [(1) calcium ionophore (ionomycin) alone (n = 191); and (2) ionomycin followed by the protein synthesis inhibitor cycloheximide (n = 207)] were evaluated for production of bovine parthenogenones. Activation with ionomycin alone resulted in a development rate of 33%, while activation with ionomycin and cycloheximide sequentially resulted in a development rate to two-cell stage of 49%. A procedure was developed to expedite accurate evaluation of activated oocytes for uniformly haploid development. Uniformly haploid parthenogenones that cleaved at least once in four days of in vitro culture were individually prepared for genetic analysis. Three techniques: (1) phosphate buffered saline; (2) TL-HEPES with 0.2% ovine serum albumin; and (3) TL-HEPES with 0.2% polyvinyl pyrrolidone were compared to harvest parthenogenones for genetic analysis. The only effective method that did not create spurious results during later genetic analysis was TL-HEPES with 0.2% polyvinyl pyrrolidone. Based on the results of this study, we estimate that an average of 5–7 uniformly haploid bovine parthenogenones can be realized from each donor (using pairs of ovaries). These parthenogenones, when maintained as family units, will be valuable for accomplishment of female-specific genetic linkage analysis. J. Exp.

 @article{ernst_crenshaw_atchley_1999, title={Effect of selection for development rate on reproductive onset in female mice}, volume={74}, ISSN={["0016-6723"]}, DOI={10.1017/S001667239900381X}, abstractNote={This research reports analyses of correlated response in reproductive onset in ICR mice after 23 
generations of restricted index selection for divergent body weight gain, early (birth–10 days) or 
later (28–56 days) in life. Long-term selection altered growth trajectories and 56 day body weight 
of individuals under different selection regimes in this study. Mice in lines under early selection 
have the same percentage mature weight at vaginal opening as controls (63%). Vaginal opening is 
delayed in mice selected for slow early growth, which take longer to reach what appears to be a 
weight threshold. In contrast, individuals in lines selected for later slow growth undergo vaginal 
opening at the same age as controls, but at a lower weight and increased percentage mature 
weight. Pre-compensation or ‘counter-balance growth’ is observed in these lines, with mice selected 
for late enhanced growth reaching 52% of mature weight at vaginal opening while mice with late 
slow growth attain 71% of mature weight prior to vaginal opening. Only 42% of mice with late 
slow growth attain first oestrus by 56 days. We speculate this is a function of growth rate and 
fat/lean ratio. Mice with early slow growth show compensatory growth, reaching first oestrus at a 
similar time to controls. We conclude that selection for growth rate has asymmetrically affected 
reproductive onset, with lines selected for suppressed gains experiencing delays in the reproductive 
onset traits measured.}, number={1}, journal={GENETICAL RESEARCH}, author={Ernst, CA and Crenshaw, PD and Atchley, WR}, year={1999}, month={Aug}, pages={55–64} }
