In vivo fertilized embryos were surgically collected from superovulated dairy cows to evaluate microinjection on embryo development and utilized the polymerase chain reaction technique for selection of transgenic embryos. Seventy-two percent of the embryos with visible pronuclei or nuclei were microinjected with DNA, and the remaining 28% served as uninjected controls. All embryos were cocultured with bovine oviductal epithelial cells. Mean final development scores of embryos within the same initial cell stage at collection were unaffected by microinjection. After 144 h of culture, 45% of the microinjected embryos developed to the morula or blastocyst stage. The transgene was detected in …

A Placebo-Controlled Randomized Trial Of The Terbutaline Pump For Prevention Of Preterm Delivery, K. Wenstrom, C. Weiner, D. Merrill, Jennifer Niebyl
Jennifer R Niebyl
To determine the efficacy of the terbutaline pump for the prevention of preterm delivery, patients in preterm labor defined by progressive cervical change underwent intravenous magnesium sulfate tocolysis (with or without oral indomethacin, as necessary), and once labor was arrested, were randomized to one of three treatment arms: terbutaline by pump, saline by pump (blinded), or oral terbutaline. If recurrent preterm labor occurred despite maximization of therapy, the treatment arm was determined and therapy was changed; saline pump and oral terbutaline were switched to terbutaline pump, terbutaline pump was switched to oral terbutaline. Patients who continued to labor were readmitted …

Premature Rupture Of The Membranes And Prolonged Latency, J. Johnson, N. Daikoku, Jennifer Niebyl, T. Johnson, V. Khouzami, F. Witter
Jennifer R Niebyl
The aim of this retrospective study in 8320 patients with premature rupture of the membranes (PROM) was to determine the consequences of prolongation of the latent period. Among patients with pregnancies of more than 37 weeks' duration, those with PROM and latent periods of more than 1 day demonstrated an increased incidence of intrapartum fever (IPF), whereas those with latent periods of more than 3 days demonstrated a marked increase in fetal (but not neonatal) deaths. Although IPF and perinatal mortality were more common in preterm pregnancies, neither was found to increase or decrease with prolonged latency, provided differences in …

Randomized Comparative Trial Of Indomethacin And Ritodrine For The Long-Term Treatment Of Preterm Labor, R. Besinger, Jennifer Niebyl, W. Keyes, T. Johnson
Jennifer R Niebyl
A randomized prospective trial was performed to compare the efficacy and safety of ritodrine and indomethacin in the long-term treatment of preterm labor. Forty patients with intact membranes in preterm labor at 23 to 34 weeks' gestation were randomized to receive either intravenous ritodrine or oral indomethacin as the first-line tocolytic agent. Successful intravenous ritodrine therapy was followed by oral terbutaline therapy, and indomethacin-treated patients continued to receive oral indomethacin. Treatment failures were defined as progressive preterm labor or patient intolerance, and these patients were treated with intravenous magnesium sulfate. Ritodrine and indomethacin were equally successful in delaying preterm birth …

Three-dimensional environments have been shown to enhance cell aggregation and osteoblast differentiation. Thus, we hypothesized that three-dimensional (3D) growth environments would enhance the mineralization rate of human embryonic palatal mesenchymal (HEPM) pre-osteoblasts. The objective of this study was to investigate the potential use of rotary cell culture systems (RCCS) as a means to enhance the osteogenic potential of pre-osteoblast cells. HEPM cells were cultured in a RCCS to create 3D enviroments. Tissue culture plastic (2D) cultures served as our control. 3D environments promoted three-dimensional aggregate formations. Increased calcium and phosphorus deposition was significantly enhanced three- to 18-fold (P < 0.001) in …

Catherine S. Bradley
OBJECTIVE: The purpose of this study was to compare outcomes after sacrocolpopexy (SC) between obese and healthy-weight women. STUDY DESIGN: Baseline and postoperative data were analyzed from the Colpopexy And Urinary Reduction Efforts (CARE) randomized trial of SC with or without Burch colposuspension in stress continent women with stages II-IV prolapse. Outcomes and complications were compared between obese and healthy-weight women. RESULTS: CARE participants included 74 obese (body mass index >/=30 kg/m(2)), 122 overweight (25-29.9 kg/m(2)), and 125 healthy-weight (18.5-24.9 kg/m(2)) women, and 1 underweight (< 18.5 kg/m(2)) woman. Compared to healthy-weight women, obese women were younger (59.0 +/- 9.9 vs 62.1 +/- 10.3 yrs; P = .04), more likely to have stage II prolapse (25.7% vs 11.2%; P = .01), and had longer operative times (189 +/- 52 vs 169 +/- 58 min; P = .02). Two years after surgery, stress incontinence, prolapse, symptom resolution, and satisfaction did not differ between the obese and healthy-weight groups. CONCLUSION: Most outcomes and complication rates after SC are similar in obese and healthy-weight women.

Thomas M Gellhaus
Two groups of women were studied in a prospective longitudinal fashion to determine the effects of a 2.5-hour infusion of magnesium sulfate upon the renin-angiotensin system. Serum magnesium concentration, angiotensin-converting enzyme concentration, and plasma renin activity were measured at uniform intervals in women with either preeclampsia or preterm labor. Plasma renin activity was significantly lower (3.9 +/- 2.2 versus 6.1 +/- 1.8 ng/mL/minute; P = .004) and angiotensin-converting enzyme significantly higher (47.1 +/- 14 versus 34.0 +/- 10 U/mL; P = .008) in women with preeclampsia than in those with preterm labor. Magnesium infusion was associated with a sustained decline …

Mark K. Santillan
SR 121566A represents a peptidomimetic glycoprotein IIb/IIIa (GP IIb/IIIa) inhibitor 3-[N- 4-[4-(aminoiminomethyl)phenyl]-1,3-thiazol-2-yl ) -N-(1-carboxymethylpiperid-4-yl) amino] propionic acid, trihydrochloride. To investigate the intravenous and subcutaneous pharmacodynamics of this agent, a primate model ( Macaca mulatta) was used. The IC50 for adenosine diphosphate (ADP) (10 micromol/L)-induced platelet aggregation in this primate platelet system was found to be 45 +/- 6 nmol/L. Comparatively in the human platelet rich plasma system, SR 121566A demonstrated an IC50 of 39 +/- 4 nmol/L. Graded doses of SR 121566A in the range of 25-400 microg/kg were administered intravenously. Blood samples were drawn from individual groups of primates …
