The hPL levels peaked at 37 weeks' gestation and then decl...hPL; Pregnancy Complications; Pregnancy, Multiple; Infant, Newborn; Birth Weight1979-08
33 Varner, Michael W.Abnormal pregnancy sonogram: selective indication for fetal karyotype.The inability to make a definitive diagnosis in the fetus with a sonographically identified abnormality often results in parental and physician uncertainty. An antenatal chromosome evaluation could resolve this uncertainty. Forty-one fetuses with an abnormal ultrasound examination were tested for ka...Chromosome Disorders; Pregnancy; Karyotyping; Abnormalities; Amniocentesis1987-01
34 Varner, Michael W.Cerebral vasculopathies masquerading as eclampsia.Obstetricians know that preeclampsia-eclampsia is a syndrome and is a final common pathway for multiple causes. It is also possible that other conditions, not always directly related to pregnancy, can mimic preeclampsia-eclampsia. One such entity is cerebral vasculopathy, an entity characterized b...Cerebrovascular Disorders; Eclampsia; Puerperal Disorders2006-02
35 Varner, Michael W.; Hatasaka, Harry H.Recurrent pregnancy loss.Recurrent pregnancy loss is a frustrating clinical dilemma for both patients and physicians because, in most cases, causes are nebulous and few treatments with proven benefit can be offered. Involved, expensive tests have frequently been proposed and their use has often filtered into clinical practi...Recurrent Pregnancy Loss; Uterus/abnormalities; Chromosome Disorders; Abortion, Habitual1994-06
36 Moon, Ann M.; Capecchi, Mario R.Roles of Fgf4 and Fgf8 in limb bud initiation and outgrowth.Although numerous molecules required for limb bud formation have recently been identified, the molecular pathways that initiate this process and ensure that limb formation occurs at specific axial positions have yet to be fully elucidated. Based on experiments in the chick, Fgf8 expression in the in...Animals; Apoptosis; Forelimb; Gene Expression Regulation, Developmental; High Mobility Group Proteins; Hindlimb; In Situ Hybridization; Mesoderm; Mice, Mutant Strains; Trans-Activators2004-09
37 Varner, Michael W.Elevated second-trimester maternal serum hCG: a marker of inadequate angiogenesis.OBJECTIVE: To measure angiogenin, a potent inducer of neovascularization and interleukin-6, as an indicator of acute inflammation, in second-trimester amniotic fluid of patients with elevated maternal serum hCG. METHODS: In this case-control study, 20 patients with elevated maternal serum hCG (at le...Angiogenesis Inducing Agents; Interleukin-6; Pregnancy Complications; hCG1998-04
38 Varner, Michael W.; Jackson, G. MarcSevere pulmonary hypertension in pregnancy following successful repair of ventricular septal defect in childhood.BACKGROUND: Because of advances in surgical repair, an increasing number of women born with structural cardiac disease now live to reproductive age. Patients treated successfully in childhood are followed for varying periods of time, then may be lost to follow-up or told that no follow-up is necessa...Pregnancy Complications, Cardiovascular; Heart Septal Defects, Ventricular; Hypertension, Pulmonary1993-10
39 Varner, Michael W.Elevations of amniotic fluid macrophage inflammatory protein-1 alpha concentrations in women during term and preterm labor.OBJECTIVE: To determine whether elevated concentrations of macrophage inflammatory protein-1 alpha (MIP-1 alpha) in amniotic fluid (AF) are related to term and preterm labor. METHODS: Amniotic fluid was obtained from women from five different clinical situations: 1) term cesarean delivery, no labor ...Amniotic Fluid; Macrophage Inflammatory Protein-1; Obstetric Labor, Premature1996-01
40 Coffin, Cheryl M.; Capecchi, Mario R.Alveolar rhabdomyosarcomas in conditional Pax3:Fkhr mice: cooperativity of Ink4a/ARF and Trp53 loss of function.Alveolar rhabdomyosarcoma is an aggressive childhood muscle cancer for which outcomes are poor when the disease is advanced.

45 Moon, Ann M.; Capecchi, Mario R.Fgf8 is required for outgrowth and patterning of the limbs.The expression pattern and activity of fibroblast growth factor-8 (FGF8) in experimental assays indicate that it has important roles in limb development, but early embryonic lethality resulting from mutation of Fgf8 in the germ line of mice has prevented direct assessment of these roles. Here we rep...Animals; Body Patterning; Bone Morphogenetic Proteins; Ectoderm2000-12-26
