The ruthenaphosphaalkenyls [Ru{P=CH(SiMe2R)}Cl(CO)(PPh3)2] (R = Me, Ph, Tol) have been prepared in good yield by the facile hydroruthenation of the respective phosphaalkynes, RMe2SiC≡P, with [RuHCl(CO)(PPh3)3]; all three compounds have been structurally characterized in the solid state. Complemented by DFT studies of these, and the precedent [Ru{P=CH(tBu)}Cl(CO)(PPh3)2], the phosphaalkenyl moie...

The response of a steel moment resisting frame (MRF) depends on the specifications of its main components, namely the columns, beams and connections. One important connection element which can significantly affect frame behavior is the panel zone (PZ). The PZ is described to be an element mainly subjected to shear stresses and its failure mode is often governed by shear yielding. Several analyt...

BACKGROUND The relationship between coronary heart disease (CHD) and the paraoxonase 2 (PON2) Ser311Cys polymorphism has received much attention. We conducted a meta-analysis on the results from published case-control studies examining this relation. MATERIAL AND METHODS A literature search was performed using PubMed and ISI Web of Knowledge databases until October 2015. Odds ratios (OR) and 95...

Previous studies have shown that intensive macropinocytosis occurs in cancer cells and neutral red (NR) is noted for its capability to enter into the cell massively through a process mimetic to macropinocytosis. In addition, trans-cinnamic acid (tCA) has been found to be an inhibitor of histone deacetylase (HDAC). In the present study, cinnamoylphenazine (CA-PZ) that consists of NR and tCA moie...

Let m be a positive integer and suppose that p is an odd prime with p ≡ 1 mod m. Suppose that a ∈ (Z/pZ)∗ and consider the polynomial xm − a. If this polynomial has any roots in (Z/pZ)∗, where the coset representatives for Z/pZ are taken to be all integers u with |u| < p/2, then these roots will form a coset of the multiplicative subgroup μm of (Z/pZ)∗ consisting of the mth roots of unity mod p...

Objectives : To evaluate diffusion-weighted imaging (DWI) with low b factors of the peripheral zone (PZ) of patients with prostatic cancer. Materials and methods : An EPI diffusion MR sequence (TE = 75 ms, TR = 4000 ms, slice thickness = 4 mm), with low diffusion factors incremented by 10 s/mm2, has been developed on a 1.5 T magnet. Axial T2-weighted images of the prostate were performed on 21 ...

Electrical stimulation of two connected cortical areas in the monkey brain, the ventral intraparietal area (VIP) in the intraparietal sulcus and the polysensory zone (PZ) in the precentral gyrus, evokes a specific set of movements. In one interpretation, these movements correspond to those typically used to defend the body from objects that are near, approaching, or touching the skin. The prese...

Reaction of 3,5-(CF(3))(2)PzLi with anhydrous RhCl(3) in THF gives [Li(THF)](2)Rh(μ-3,5-(CF(3))(2)Pz)(4) (1) as a rare example of a mononuclear, paramagnetic Rh(II) complex (Pz = pyrazolate).

The reaction of a sterically demanding sodium pyrazolate complex with n-butylsodium and diphenylsilane afforded the first well-defined molecular sodium hydride complex [(pz)6Na7H] (pz = 3,5-di-tert-butylpyrazolate) that could be structurally characterised.

Driven by advances in materials and computer science, researchers are attempting to design systems where the computer and material are one and the same entity. Using theoretical and computational modeling, we design a hybrid material system that can autonomously transduce chemical, mechanical, and electrical energy to perform a computational task in a self-organized manner, without the need for...
