Resting-State Functional Connectivity in the Infant Brain: Methods, Pitfalls, and Potentiality.

Frontiers in pediatrics

Mongerson CRL, Jennings RW, Borsook D, Becerra L, Bajic D.
PMID: 28856131
Front Pediatr. 2017 Aug 14;5:159. doi: 10.3389/fped.2017.00159. eCollection 2017.

Early brain development is characterized by rapid growth and perpetual reconfiguration, driven by a dynamic milieu of heterogeneous processes. Postnatal brain plasticity is associated with increased vulnerability to environmental stimuli. However, little is known regarding the ontogeny and temporal...

Int J Antimicrob Agents. 2015 Jul 09; doi: 10.1016/j.ijantimicag.2015.05.021. Epub 2015 Jul 09.

This study aimed to increase the sensitivity of Caenorhabditis elegans as an infection model for detection of minor differences in virulence or fitness between different Acinetobacter baumannii strains with known resistance and virulence mechanisms. Selected A. baumannii strains and...

Using prerecorded hemodynamic response functions in detecting prefrontal pain response: a functional near-infrared spectroscopy study.

Neurophotonics

Peng K, Yücel MA, Aasted CM, Steele SC, Boas DA, Borsook D, Becerra L.

Neurophotonics. 2018 Jan;5(1):011018. doi: 10.1117/1.NPh.5.1.011018. Epub 2017 Oct 16.

Currently, there is no method for providing a nonverbal objective assessment of pain. Recent work using functional near-infrared spectroscopy (fNIRS) has revealed its potential for objective measures. We conducted two fNIRS scans separated by 30 min and measured the...

In the title compound, C10H7FN2OS, the mean plane of the central amide fragment (r.m.s. deviation = 0.048 Å) makes dihedral angles of 35.28 (8) and 10.14 (12)° with those of the fluoro-benzene and thia-zole rings, respectively. The thia-zole S...

Neural circuitry underlying pain modulation: expectation, hypnosis, placebo.

Trends in cognitive sciences

Ploghaus A, Becerra L, Borras C, Borsook D.
PMID: 12757820
Trends Cogn Sci. 2003 May;7(5):197-200. doi: 10.1016/s1364-6613(03)00061-5.

The ability to predict the likelihood of an aversive event is an important adaptive capacity. Certainty and uncertainty regarding pain cause different adaptive behavior, emotional states, attentional focus, and perceptual changes. Recent functional neuroimaging studies indicate that certain and...

Time-resolved gas-phase kinetic and quantum chemical studies of reactions of silylene with chlorine-containing species. 2. CH3Cl.

The journal of physical chemistry. A

Becerra R, Cannady JP, Walsh R.
PMID: 16722683
J Phys Chem A. 2006 Jun 01;110(21):6680-6. doi: 10.1021/jp055885l.

Time-resolved kinetic studies of the reaction of silylene, SiH2, generated by laser flash photolysis of both silacyclopent-3-ene and phenylsilane, have been carried out to obtain second-order rate constants for its reaction with CH3Cl. The reaction was studied in the...

Fluorimetric sequential injection determination of magnesium using 8-hydroxiquinoline-5-sulfonic acid in a micellar medium.

A fluorimetric sequential injection method for the determination of magnesium is proposed. The system is based on the complex formation between Mg(II) and 8-hydroxyquinoline-5-sulfonic acid (HQS). The reaction was carried out in the presence of ethylene glycol-bis(beta-aminoethyl ether)-N,N,N',N'-tetraacetic acid...
