The role of perceived team effectiveness in improving chronic illness care.

Medical care

Shortell SM, Marsteller JA, Lin M, Pearson ML, Wu SY, Mendel P, Cretin S, Rosen M.
PMID: 15586830
Med Care. 2004 Nov;42(11):1040-8. doi: 10.1097/00005650-200411000-00002.

BACKGROUND/OBJECTIVES: The importance of teams for improving quality of care has received increased attention. We examine both the correlates of self-assessed or perceived team effectiveness and its consequences for actually making changes to improve care for people with chronic...

Exploring and expanding the structural diversity of self-assembling dendrons through combinations of AB, constitutional isomeric AB2, and AB3 biphenyl-4-methyl ether building blocks.

Chemistry (Weinheim an der Bergstrasse, Germany)

Percec V, Holerca MN, Nummelin S, Morrison JJ, Glodde M, Smidrkal J, Peterca M, Rosen BM, Uchida S, Balagurusamy VS, Sienkowska MJ, Heiney PA.
PMID: 16841348
Chemistry. 2006 Aug 16;12(24):6216-41. doi: 10.1002/chem.200600178.

General, efficient and inexpensive methods for the synthesis of dendritic building blocks methyl 3',4'-dihydroxybiphenyl-4-carboxylate, 3',5'-dihydroxybiphenyl-4-carboxylate, and methyl 3',4',5'-trihydroxybiphenyl-4-carboxylate were elaborated. In all syntheses the major step involved an inexpensive Ni(II)-catalyzed Suzuki cross-coupling reaction. These three building blocks were employed...

Glucose-6-phosphatase in tubular endoplasmic reticulum of hepatocytes.

Science (New York, N.Y.)

Rosen SI, Kelly GW, Peters VB.
PMID: 17775162
Science. 1966 Apr 15;152(3720):352-4. doi: 10.1126/science.152.3720.352.

The histochemical localization of glucose-6-phosphatase activity in neonatal mouse liver was studied under electron microscopy. The activity was demonstrated in the tubular endoplasmic reticulum, which pervades the glycogen areas of the cell during glycogenolysis. Activity was also demonstrated in...

Bound on Lorentz and CPT violating boost effects for the neutron.

Physical review letters

Canè F, Bear D, Phillips DF, Rosen MS, Smallwood CL, Stoner RE, Walsworth RL, Kostelecký VA.
PMID: 15601138
Phys Rev Lett. 2004 Dec 03;93(23):230801. doi: 10.1103/PhysRevLett.93.230801. Epub 2004 Nov 30.

A search for an annual variation of a daily sidereal modulation of the frequency difference between colocated 129Xe and 3He Zeeman masers sets a stringent limit on boost-dependent Lorentz and CPT violation involving the neutron, consistent with no effect...

Sulfuric Acid droplet formation and growth in the stratosphere after the 1982 eruption of el chichon.

Science (New York, N.Y.)

Hofmann DJ, Rosen JM.
PMID: 17734833
Science. 1983 Oct 21;222(4621):325-7. doi: 10.1126/science.222.4621.325.

The eruption of El Chichón Volcano in March and April 1982 resulted in the nucleation of large numbers of new sulfuric acid droplets and an increase by nearly an order of magnitude in the size of the preexisting particles...

Diamidodipyrrins: versatile bipyrrolic ligands with multiple metal binding modes.

Inorganic chemistry

Thoi VS, Stork JR, Niles ET, Depperman EC, Tierney DL, Cohen SM.
PMID: 18939825
Inorg Chem. 2008 Nov 17;47(22):10533-41. doi: 10.1021/ic8011876. Epub 2008 Oct 22.

A straightforward, facile synthesis of diamidodipyrromethenes (diamidodipyrrins, DADP (R,R')) is presented. These tetradentate ligands readily form complexes with metal ions such as Ni (2+) and Cu (2+) and can adopt different binding modes with these metals. One version of...

Heterometallic metal-organic frameworks based on tris(dipyrrinato) coordination complexes.

Inorganic chemistry

Halper SR, Cohen SM.
PMID: 15679375
Inorg Chem. 2005 Feb 07;44(3):486-8. doi: 10.1021/ic048289z.

A novel class of heterometallic metal-organic frameworks (MOFs) has been synthesized and characterized. The MOFs rely on the use of tris(dipyrrinato) coordination complexes as the bridging structure and silver(I) ions as the linking unit. The building blocks and resulting...

The occurrence of the tropical bedbug (Cimex hemipterus, Fabricius) in poultry barns in Israel.

Avian pathology : journal of the W.V.P.A

Rosen S, Hadani A, Lavi AG, Berman E, Bendheim U, Hisham AY.
PMID: 18766620
Avian Pathol. 1987;16(2):339-42. doi: 10.1080/03079458708436381.

The occurrence of the tropical bedbug (Cimex hemipterus Fabricius) in poultry houses in Israel is described. Despite the heavy infestation serious losses have not been registered and no clinical signs observed. Treatment of the barns and accessories with 2%...

Transient fluorescence of the off state in blinking CdSe/CdS/ZnS semiconductor nanocrystals is not governed by Auger recombination.

Physical review letters

Rosen S, Schwartz O, Oron D.
PMID: 20482017
Phys Rev Lett. 2010 Apr 16;104(15):157404. doi: 10.1103/PhysRevLett.104.157404. Epub 2010 Apr 16.

The observed intermittent light emission from colloidal semiconductor nanocrystals has long been associated with Auger recombination assisted quenching. We test this view by observing transient emission dynamics of CdSe/CdS/ZnS semiconductor nanocrystals using time-resolved photon counting. The size and intensity...
