Spence HR, Aslam AM, Hofer MA, Brunelli SA, Shair HN.
PMID: 27066218
Ecol Evol. 2016 Feb 24;6(7):1922-9. doi: 10.1002/ece3.1907. eCollection 2016 Apr.

Selective breeding and natural selection that select for one trait often bring along other correlated traits via coselection. Selective breeding for an infantile trait, high or low call rates of isolation-induced ultrasonic vocalization of rat pups, also alters functions...

Protonated Carboxyl Anchor for Stable Adsorption of Ru N749 Dye (Black Dye) on a TiO2 Anatase (101) Surface.

J Phys Chem Lett. 2012 Feb 16;3(4):472-7. doi: 10.1021/jz201583n. Epub 2012 Jan 30.

We have investigated the adsorption stability of ruthenium N749 dye [black dye (BD)], a highly efficient dye for dye-sensitized solar cells (DSCs), through protonated and deprotonated carboxyl group anchors on a TiO2 anatase (101) surface by using first-principles calculations....

Conserved antigenic sites between MERS-CoV and Bat-coronavirus are revealed through sequence analysis.

Source code for biology and medicine

Sharmin R, Islam AB.
PMID: 26962326
Source Code Biol Med. 2016 Mar 09;11:3. doi: 10.1186/s13029-016-0049-7. eCollection 2016.

BACKGROUND: MERS-CoV is a newly emerged human coronavirus reported closely related with HKU4 and HKU5 Bat coronaviruses. Bat and MERS corona-viruses are structurally related. Therefore, it is of interest to estimate the degree of conserved antigenic sites among them....

PMID: 26839829
Sci Pharm. 2015 Mar 06;83(3):445-52. doi: 10.3797/scipharm.1501-13. Print 2015.

We describe the synthesis of two positional isomers and a desfluoro impurity of Voriconazole starting with Friedel-Crafts acylation of mono- and difluorobenzene. These isomers are the crucial components in determining the quality of Voriconazole during its manufacturing from the...

Anc Sci Life. 2014 Jan;33(3):162-4. doi: 10.4103/0257-7941.144620.

CONTEXT: Thrombus formation inside the blood vessels obstructs blood flow through the circulatory system leading hypertension, stroke to the heart, anoxia, and so on. Thrombolytic drugs are widely used for the management of cerebral venous sinus thrombosis patients, but...

Panchromatic donor-acceptor-donor conjugated oligomers for dye-sensitized solar cell applications.

ACS applied materials & interfaces

Stalder R, Xie D, Islam A, Han L, Reynolds JR, Schanze KS.
PMID: 24807377
ACS Appl Mater Interfaces. 2014 Jun 11;6(11):8715-22. doi: 10.1021/am501515s. Epub 2014 May 07.

We report on a sexithienyl and two donor-acceptor-donor oligothiophenes, employing benzothiadiazole and isoindigo as electron-acceptors, each functionalized with a phosphonic acid group for anchoring onto TiO2 substrates as light-harvesting molecules for dye sensitized solar cells (DSSCs). These dyes absorb...

Novel acid-catalyzed rearrangement of methanofullerenes bearing an alpha-ylidic ester to cyclopentanofullerenes: a vinyl cyclopropane-type ring expansion.

The Journal of organic chemistry

Chuang SC, Islam A, Huang CW, Shih HT, Cheng CH.
PMID: 12737558
J Org Chem. 2003 May 16;68(10):3811-6. doi: 10.1021/jo030009u.

A novel acid-catalyzed ring expansion of methanofullerenes bearing an alpha-ylidic ester has been investigated. Treatment of dialkyl acetylenedicarboxylate and tricycloalkylphosphine with C(60) led to the isolation of a methanofullerene ylide after passing the reaction mixtures through a basic alumina...
