• #### Structure of tropomyosin at 7A resolution ﻿

(1995)
The crystal structure of tropomyosin has been determined by X-ray diffraction analysis at 7A resolution. Tropomyosin is a 400A-long muscle regulatory protein that consists of two parallel 33,000 Dalton alpha helices wound ...
• #### Structure, wettability, and barrier properties of self-assembled monolayers on metallic surfaces ﻿

(2007)
Self-assembled monolayers (SAMs) offer a convenient approach for fabricating molecularly tailored interfaces with well-defined compositions, structures, and thicknesses. SAMs have been suggested for use as corrosion barriers, ...

• #### Structure/function studies of humanp53 protein ﻿

(2001)
Cellular p53 response, including apoptosis and cell cycle arrest, is reportedly due to "activation" of otherwise "latent" protein, a process that has been mimicked in vitro by the use of agents that interact with the p53 ...
• #### Structured Illumination in a Fiber-Optic Microendoscope to Image Nuclear Morphometry in Columnar Epithelium ﻿

(2015-03-23)
Fiber-optic microendoscopes have shown promise to image the changes in nuclear morphometry that accompany the development of precancerous lesions in tissue with squamous epithelium such as in the oral mucosa and cervix. ...
• #### Structured secant updates for nonlinear constrained optimization ﻿

(1991)
Two new updates are presented, the UHU update and a modified Gurwitz update, for approximating the Hessian of the Lagrangian in nonlinear constrained optimization problems. Under the standard assumptions, the new UHU ...
• #### Structures and interactions of tropomyosin with caldesmon and troponin ﻿

(1997)
Tropomyosin plays a central role in the regulation of skeletal, cardiac, and smooth muscle regulation. The regulatory properties of tropomyosin are mediated by its interactions with muscle-specific tropomyosin binding ...
• #### STRUCTURES AND PROPERTIES OF INORGANIC HALIDE RADICALS AND MOLECULES ﻿

(1977)

(2002)
'Structures of agency' takes as its model the expanding cone of simultaneous pathways the photon travels through as it propagates through space. That image, together with the expanding cones of Richard Serra's Clara-Clara ...
• #### Structures, reaction kinetics, and dioxygen chemistry of some pentacoordinate Schiff base copper complexes ﻿

(1987)
Crystal structures of the Cu(I)/Cu(II) complexes of the pentadentate nitrogen-bonding Schiff-base ligand, $\{$bis-2,6- (1-(2-pyridin-2-ylethylimino)ethyl) pyridine$\}$, (Cu$\sp{\rm I/II}$(py)$\sb2$DAP) $\sp{\rm n+}$, 1, ...
• #### Structurial studies of thelac repressor using homology modeling and combinatorial mutations ﻿

(1996)
The core domain (residues 62-323) of the regulatory protein lac repressor has been aligned to several sugar binding proteins of known structure. The overall homology based on two separate matrix scoring systems (minimum ...

(1979)
• #### Studies in French cultural and intellectual history ﻿

(1998)
Four topics in the cultural and intellectual history of France are presented. The first is a comparative study examining the relationship between seventeenth-century philosophy and literature. It argues that elements of ...

• #### Studies in nerve electrophysiology ﻿

(1989)
Two separate studies in nerve electrophysiology are described. Both are seen to have clinical relevance in terms of the treatment and diagnosis of peripheral nervous system dysfunction and injury. The first study, ...
