A study on the relationship between parity and differentiation of granulated metrial gland cells
Placenta, 1996Granulated metrial gland (GMG) cells are a feature consistently associated with rodent pregnancy. Little information is available, however, on the life history of GMG cells in pregnancies other than first pregnancy. To determine if the frequency of GMG cells in the mesometrial triangle of mice is altered by parity, a study of histological sections from

Parity models of cell proliferation
Journal of Theoretical Biology, 1974Abstract Models of the cell cycle are developed and simulated for renewing and for exponentially growing populations. Type A corresponds to the author's previous model ( Barrett, 1966 , Barrett, 1966 ). Type B incorporates a resting or regenerating phase, recurring regularly every few cycles, with an endogeneous rhythm.

Regulation of Mammary Progenitor Cells by p53 and Parity
2010Abstract : Breast cancer is the most frequent cancer among women in the United States. A full term pregnancy early in reproductive life can reduce breast cancer incidence in women by up to 50% and p53, an important tumor suppressor gene, was shown to be a major effector for this protection effect.

Dynamic behavior of spatial solitons propagating along Scarf II parity–time symmetric cells
Journal of the Optical Society of America B, 2012Using a nonstationary state solution to the nonlinear Schrodinger equation (NLSE), we report the results of our numerical investigation on the swing behavior of spatial solitons propagating along waveguides whose refractive indices in the transverse direction are perturbed by Scarf II type parity–time symmetric profiles.

Up‐Regulation of Natural Killer Cell Cytotoxicity by Interleukin‐2: The Effect of Sex and Parity
American Journal of Reproductive Immunology, 1999PROBLEM: Peripheral blood lymphocytes (PBLs) from some, but not all, female donors showed increased cytotoxicity in response to interleukin (IL)‐2.METHOD OF STUDY: The effect of IL‐2 on natural killer (NK) cell cytotoxicity was compared in nulliparous females, parous females, and males.

Inheritance of somatic cell count and its genetic relationship with milk yield in different parities
Livestock Production Science, 1988Abstract During the introduction of a cell count program, monthly somatic cell counts were collected between March 1985 and June 1986 for 3376 Friesian cows in 86 herds in The Netherlands. There were 977 cows in first parity, representing 42 sires; 718 cows in second parity, representing 28 sires; 1555 cows in third or greater parities, representing ...

Small Ruminant Research, 2000
Twenty-four Comisana ewes, with no history of mastitis, were included in this study, with eight ewes each in parities 1, 2 and 3. Groups were separately penned on straw litter and ewes were individually checked for yield, composition, renneting properties and bacteriological characteristics of milk from January, when separated from their lambs (50+/-3 ...

Regulation Of Mammary Stem/Progenitor Cells By P53 And Parity
2011Breast cancer is the most common tumor among women with inherited mutations in the p53 gene (Li-Fraumeni syndrome). The tumors represent the basal-like subtype which has been suggested to originate from mammary stem/progenitor cells. In mouse mammary epithelium, mammosphere-forming potential was increased with decreased dosage of the gene encoding the ...

Journal of Fusion Energy, 2010
We describe kinetic electromagnetic particle-in-cell simulation of a field reversed configuration with rotating magnetic fields (RMF). The energy-conserving algorithm calculates RMF penetration, gas breakdown and field reversal for the odd-parity RMF, PFRC device.

Neuregulin Driven Cell Differentiation, Transformation, and Parity of Luminal Breast Cancer
2013Abstract : Studies have shown that ErbB3 and ErbB4 (the neuregulin receptors) are required for growth and survival of the two major luminal mammary epithelial cell types, the ductal luminal mammary epithelium, and the milk-producing alveolar mammary epithelium.
