Dinuclear and trinuclear ferrocene complexes {[Fc2BMe2]Li, [Fc-BMe2-fc-BMe2-Fc]Li2, Fc2B(pyind), [Fc2B(bipy)]PF6, [Fc-B(bipy)-fc-B(bipy)-Fc](PF6)2} bearing anionic, uncharged, and cationic four-coordinate boron bridges have been synthesized (Fc: ferrocenyl; fc: 1,1'-ferrocenylene; pyind: 5-fluoro-2-(2'-pyridyl)indolyl; bipy: 2,2'-bipyridyl). The molecular structures of [Fc2BMe2]Li(12-crown-4)2,...

background and objective: febrile convulsions (fc) are the most common seizure disorder in children. lumbar puncture should be considered in any case with fc who is suspected to intracranial infections. this study determined white blood cell and polymorphonuclear cell counts, and protein and glucose levels in cere-brospinal fluids (cfs) of children hospitalized with fc. methods: in this cross s...

Recently Dent and Mercer have introduced an algorithm called minimal forward checking (MFC) which always performs no worse than forward checking (FC) in terms of number of compatibility checks and node expanded given the same variable and value orderings. In this paper we describe an algorithm which extends MFC with backmarking and conflict-directed backtracking. The new algorithm has a smaller...

BACKGROUND Toca 511, a gamma retroviral replicating vector encoding cytosine deaminase, used in combination with 5-fluorocytosine (5-FC) kills tumor by local production of 5-fluorouracil (5-FU), inducing local and systemic immunotherapeutic response resulting in long-term survival after cessation of 5-FC. Toca 511 and Toca FC (oral extended-release 5-FC) are under investigation in patients with...

Functional connectivity (FC) in resting-state functional magnetic resonance imaging (rs-fMRI) is widely used to find coactivating regions in the human brain. Despite its widespread use, the effects of sex and age on resting FC are not well characterized, especially during early adulthood. Here we apply regression and graph theoretical analyses to explore the effects of sex and age on FC between...

Receptors for the Fc region of IgG (Fc gamma R) mediate internalization of opsonized particles by human neutrophils (PMN) and mononuclear phagocytes. Cross-linking of Fc gamma R leads to activation of protein tyrosine kinases and phosphorylation of immunoreceptor tyrosine-based activation motifs (ITAMs) within Fc gamma R subunits, both obligatory early signals for phagocytosis. Human PMN consti...

Receptors for the Fc domain of IgG on cells of hematopoietic lineage perform important functions, including stimulation of the ingestion of IgG-coated cells. In examining the function of Fc gamma receptor isoforms by transfection into COS-1 cells, we have observed that Fc gamma RIIA induces the binding and phagocytosis of IgG-sensitized RBCs (EA) and that transfected COS-1 cells can serve as a ...

1,1’-Diaminoferrocene (1) was converted to α-aminonitriles fc[NHC(CN)MeR’]2 (fc=1,1’-ferrocenediyl; 2 a: R’=Me, b: R’=Ph, c: R’=tBu) by reaction with ketones MeC(O)R’ in the presence of NaCN/HOAc or diimine fc(N=CPh2)2 (3) condensation Ph2CO. Treatment a–c 3 MeLi furnished fc(NHR)2 (4 R=tBu, 4 R=CMe2Ph, R=CMe2tBu, d: R=CMePh2) after aqueous work-up. The formylative cyclisation a–d fc[(NR)2CH][B...

A comparison of the molecular structures of mono-, di- and tetraborylated ferrocenes [Fc{B(R(1))(R(2))}] (R(1)/R(2)=Br/Br, Br/Fc, Br/Me, Me/Me, Me/OH, OMe/OMe), 1,1'-[fc{B(R(1))(R(2))}(2)] (R(1)/R(2)=Br/Br, Br/Me, OMe/OMe), and 1,1',3,3'-[Fe{C(5)H(3)(BMe(2))(2)}(2)] revealed the boryl substituent(s) to be bent out of the Cp ring plane towards the iron center. The corresponding dip angle alpha* ...
