Journal ArticleDOI
Neuroendocrine-gonadal axis in men: frequent sampling of LH, FSH, and testosterone.
Daniel I. Spratt,Louis St. L. O’Dea,David A. Schoenfeld,James P. Butler,P. N. Rao,William F. Crowley +5 more
TL;DR: A previously unappreciated spectrum of gonadotropin and T secretory patterns was observed in normal men, and results suggested a relative refractory period at the level of the hypothalamus or pituitary.
Journal ArticleDOI
Propulsion and navigation within the advancing monolayer sheet
Jae Hun Kim,Xavier Serra-Picamal,Dhananjay T. Tambe,Enhua H. Zhou,Chan Young Young Park,Monirosadat Sadati,Jin-Ah Park,Ramaswamy Krishnan,Bomi Gweon,Emil Millet,James P. Butler,James P. Butler,Xavier Trepat,Xavier Trepat,Jeffrey J. Fredberg +14 more
TL;DR: Using monolayer stress microscopy, it is found that cells located near the island exert tractions that pull systematically towards this island regardless of whether the cells approach the island, migrate tangentially along its edge or, paradoxically, recede from it.
Journal ArticleDOI
Selected contribution: time course and heterogeneity of contractile responses in cultured human airway smooth muscle cells.
Ben Fabry,Geoffrey N. Maksym,Stephanie A. Shore,Paul E. Moore,Reynold A. Panettieri,James P. Butler,Jeffrey J. Fredberg +6 more
TL;DR: It is concluded that HASM cells in culture exhibit a clear, although heterogeneous, response to contractile and relaxing agonists and express the essential mechanical features characteristic of the contractile response observed at the tissue level.
Journal ArticleDOI
Monolayer Stress Microscopy: Limitations, Artifacts, and Accuracy of Recovered Intercellular Stresses
Dhananjay T. Tambe,Ugo Croutelle,Xavier Trepat,Chan Young Young Park,Jae Hun Kim,Emil Millet,James P. Butler,Jeffrey J. Fredberg +7 more
TL;DR: New analytical, numerical, and experimental investigations validate Monolayer Stress Microscopy within broad but well-defined limits of applicability.
Journal ArticleDOI
Magnetic particle motions within living cells. Physical theory and techniques
Peter A. Valberg,James P. Butler +1 more
TL;DR: The physical principles relevant to magnetometry are presented and models for intracellular particle motion driven by thermal, elastic, or cellular forces are suggested and described.
