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.

Impact of parity number, milk production and somatic cell count on the reproduction of Holstein cows
Journal of Dairy Research, 2023AbstractThis research communication describes the reproductive and productive parameters and somatic cell count (SCC) of primiparous and multiparous cows from specialized dairy Holstein herds in South region of Brazil, and correlates these parameters using test-day records.

Asymmetric Evolution of Interacting Solitons in Parity Time Symmetric Cells
IEEE Journal of Quantum Electronics, 2013We show the evolution of two fundamental bright solitons after being simultaneously launched into nonlinear triangular parity time (PT) symmetric waveguides, at mirrored transverse input positions. Numerical simulations show, whether below or above the phase transition, in general the retarded soliton propagating along the gain side and the advanced ...

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 ...

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 ...

Catalyst Activity Targets for Performance Parity in Hydroxide Exchange Membrane Fuel Cells
ECS Meeting Abstracts, 2017HEMFCs offer several potential cost advantages over proton exchange membrane fuel cells (PEMFCs), most notably improved kinetics and stability for platinum group metal (PGM)-free catalysts. However, these materials cost advantages can be offset by the lower power density of HEMFCs. To support the ultimate goal of performance parity between HEMFCs and
