Sequence variation in ligand binding sites in proteins

Magliery, Thomas J.; Regan, Lynne ( 2005-09-30 )

Background: The recent explosion in the availability of complete genome sequences has led to the cataloging of tens of thousands of new proteins and putative proteins. Many of these proteins can be structurally or ...

Ser170 of Bacillus thuringiensis Cry1Ab δ-endotoxin becomes anchored in a hydrophobic moiety upon insertion of this protein into Manduca sexta brush border membranes

Alzate, Oscar; Hemann, Craig F.; Osorio, Cristina; Hille, Russ; Dean, Donald H. ( 2009-10-19 )

Background: Three spin-labeled mutant proteins, mutated at the beginning, middle, and end of α-helix 5 of the Bacillus thuringiensis Cry1Ab δ-endotoxin, were used to study the involvement of these specific amino acid ...

Serum Zinc Correlates with Parent- and Teacher-Rated Inattention in Children with Attention-Deficit/Hyperactivity Disorder

Arnold, L. Eugene; Bozzolo, Hernan; Hollway, Jill; Cook, Amy; DiSilvestro, Robert A.; Bozzolo, Dawn R.; Crowl, Lindsay; Ramadan, Yaser; Williams, Craig ( 2005 )

Objective: The aim of this study was to explore the relationship of zinc nutrition to the severity of attentiondeficit/ hyperactivity disorder (ADHD) symptoms in a middle-class American sample with well-diagnosed ADHD. ...

Shape differences rather than size differences between castes in the Neotropical swarm-founding wasp Metapolybia docilis (Hymenoptera: Vespidae, Epiponini)

Baio, Mário V.; Noll, Fernando B.; Zucchi, Ronaldo ( 2003-05-13 )

Background: Swarm-founding epiponine wasps are an intriguing group of social insects in which colonies are polygynic (several queens share reproduction) and differentiation between castes is often not obvious. However, ...

Short report: Patterns of US federal autism research funding during 2017–2019

Harris, Lauren; Gilmore, Daniel; Longo, Anne; Hand, Brittany ( 2021 )

In 2017, the Interagency Autism Coordinating Committee, a federal advisory panel consisting of autism researchers and community members, recommended that funders of autism research prioritize research projects on: (1) ...

Sickle cell trait and priapism: a case report and review of the literature

Birnbaum, Brian F.; Pinzone, Joseph J. ( 2008-12-30 )

Background A 32 year-old African-American man presented to our institution after attempting suicide via ingestion with quetiapine. He had reported a history of several days of substance abuse with alcohol, cocaine and ...

Similarity renormalization group for nucleon-nucleon interactions

Bogner, S. K.; Furnstahl, R. J.; Perry, R. J. ( 2007-06-13 )

The similarity renormalization group (SRG) is based on unitary transformations that suppress off-diagonal matrix elements, forcing the Hamiltonian toward a band-diagonal form. A simple SRG transformation applied to ...

Simulation of the Formation and Morphology of Ice Mantles on Interstellar Grains

Cuppen, H. M.; Herbst, Eric ( 2007-10-10 )

Although still poorly understood, the chemistry that occurs on the surfaces of interstellar dust particles profoundly affects the growth of molecules in the interstellar medium. An important set of surface reactions produces ...

Single-particle density of states of a superconductor with a spatially varying gap and phase fluctuations

Valdez-Balderas, Daniel; Stroud, David ( 2006-11-13 )

Recent experiments have shown that the superconducting energy gap in some cuprates is spatially inhomogeneous. Motivated by these experiments, and using exact diagonalization of a model d-wave Hamiltonian, combined with ...

Skeletal P/Ca tracks upwelling in Gulf of Panamá coral: Evidence for a new seawater phosphate proxy

LaVigne, M.; Field, M. P.; Anagnostou, E.; Grottoli, A. G.; Wellington, G. M.; Sherrell, R. M. ( 2008-03-06 )

The supply of limiting nutrients to the low latitude ocean is controlled by physical processes linked to climate variations, but methods for reconstructing past nutrient concentrations in the surface ocean are few and ...

Slip-length measurement of confined air flow using dynamic atomic force microscopy

Maali, Abdelhamid; Bhushan, Bharat ( 2008-08-26 )

We present an experimental measurement of the slip length of air flow close to solid surfaces using an atomic force microscope (AFM) in dynamic mode. The air was confined between a glass surface and a spherical glass ...

Slow Diffusive Gravitational Instability Before Decoupling

Thompson, Todd A. ( 2010-02-01 )

Radiative diffusion damps acoustic modes at large comoving wavenumber (k) before decoupling ("Silk damping"). In a simple WKB analysis, neglecting moments of the temperature distribution beyond the quadrupole (the ...

The small molecule curcumin analog FLLL32 induces apoptosis in melanoma cells via STAT3 inhibition and retains the cellular response to cytokines with anti-tumor activity
