Recent toxicology studies suggest that nanosized aggregates of fullerene molecules can enter cells and alter their functions, and also cross the blood-brain barrier. However, the mechanisms by which fullerenes penetrate and disrupt cell membranes are still poorly understood. Here we use computer simulations to explore the translocation of fullerene clusters through a model lipid membrane and th...

Fullerenes are among the strongest antioxidants and are characterized as "radical sponges." The research on biomedicinal applications of fullerenes has achieved significant progress since the landmark publication by Friedman et al in 1993. Fullerene-biomolecule conjugates have become an important area of research during the past 2 decades. By a thorough literature search, we attempt to update t...

The synthesis and characterization of new zirconium permethylpentalene (form)amidinate complexes are described: Pn*Zr{N(Dipp)2CH}Cl (1), Pn* = ?8-C8Me6 Dipp 2,6-iPr-C6H3; [Pn*Zr{N(p-tol)2CH}Cl]2 (2), p-tol 4-Me-C6H4; [Pn*Zr{N(iPr)2CMe}Cl]2 (3); Pn*Zr{N(iPr)2CPh}Cl (4); Pn*Zr{N(4-Me-C6H4)2CH}2 (5); [Pn*Zr{N(iPr)2CCH2}]2 (6); Pn*Zr{N(iPr)2CPh}(O-2,6,-Me-C6H3) (7). monohalide derivatives 1–4 demon...

Diorganozinc compounds (ZnR2) with R = CH2Ph or CH2CH=CH2 react with 2,6-bisiminopyridines ((iPr)BIP) to afford thermally stable dihydropyridinate(-1) complexes, and do not react if R = CH2SiMe3 or CH2CMe2Ph. NMR studies reveal that dibenzylzinc binds (iPr)BIP at -80 °C, yielding the unstable complex [Zn(CH2Ph)2((iPr)BIP)]. Above -20 °C, this undergoes selective alkyl migration to the remote 4 ...

Private rights in living objects have always been controversial. Agriculture provided the first wave in human civilization. Therefore, agriculture including plant breeding and agricultural methods pre-dated any form of IPR protection unlike industry and commerce. Traditionally, IPR was not applied to agriculture. In recent times, this position has changed and increasingly agriculture is seen as...

The ability of gold-hydroxides to fix CO2 is reported. [Au(IPr)(OH)] and [{Au(IPr)}2(μ-OH)][BF4] react with atmospheric CO2 to form the trigold carbonate complex [{Au(IPr)}3(μ(3)-CO3)][BF4]. Reactivity studies revealed that this complex behaves as two basic and one cationic Au centres, and that it is catalytically active. DFT calculations and kinetic experiments have been carried out.

A novel fullerene-porphyrin-fullerene triad linked by the axial coordination of tin(IV) porphyrin is reported, exhibiting strong pi-pi interactions between the tin porphyrin and fullerene moieties owing to their close proximity.

The long-term outcomes of interdisciplinary pain rehabilitation (IPR) in patients with chronic musculoskeletal (CMP) and its predictors has been studied to a limited extent. In this historical cohort study, functioning, satisfaction life domains, were assessed at baseline, discharge, 6–15 years follow-up. At follow-up, most (77%) rated the effects IPR as temporarily or persistently positive. ga...

A series of six fullerene-linker-fullerene triads have been prepared by the stepwise addition of the fullerene cages to bridging moieties thus allowing the systematic variation of fullerene cage (C60 or C70) and linker (oxalate, acetate or terephthalate) and enabling precise control over the inter-fullerene separation. The fullerene triads exhibit good solubility in common organic solvents, hav...

The coordination properties of the EN ligands N-(2-pyridinyl)amino-diphenylphosphine sulfide, N-(2-pyridinyl)amino-diisopropylphosphine sulfide, N-(2-pyridinyl)amino-diphenylphosphine selenide, N-(2-pyridinyl)amino-diisopropylphosphine selenide towards copper(I) precursors CuX (X = Br, I), [Cu(IPr)Cl] (IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene), and [Cu(CH(3)CN)(4)]PF(6) were studi...
