Hemophilia A is caused by a deficiency of actor-Vlll procoagulant (NIII) activity. The current treatment by frequent infusions of plasma-derived Nlll concentrates is very effective but has the risk of transmittance of blood-borne viruses (human immunodeficiency virus IHIVI, hepatitis viruses). Use of recombinant DNA-derived Nlll as well as gene therapy could make hemophilia treatment independen...

Reactions between K[TpFe(CN)3] (Tp- = hydrotris(1-pyrazolyl)borate) and M(ClO4)2 x 6H2O (M = Co or Ni) in a mixture of acetonitrile and methanol afford, upon crystallization via THF vapor diffusion, [Tp8(H2O)12Co6Fe8(CN)24](ClO4)4.12THF x 7H2O (1) and [Tp8(H2O)12Ni6Fe8(CN)24](ClO4)4.12THF x 7H2O (2). Both compounds contain cyano-bridged clusters with a face-centered cubic geometry, wherein octa...

KT Mon has been considered as a classical nova in 1942 based on its light curve and spectroscopy. However, we noticed a unusual feature for a nova soon after its maximum: the early presence of high excitation emission lines such as HeII and NIII. We propose previously overlooked interpretations that KT Mon can be either a WZ Sge-type dwarf nova and an X-ray transient, although the possibility o...

The complete life cycle of Triatoma flavida, weekly fed on hens, was studied at 28+/-2 degrees C and 80+/-10% RH. Aspects related to hatching, life span, mortality and feeding behavior for each stage of its life cycle were evaluated. The hatching rate observed for 100 eggs was 93% with an average incubation period of 27.2 days. Sixty-two nymphs completed the cycle and the mean egg to adult deve...

A simple Ni(II)(TPA) complex [TPA = tris(2-pyridylmethyl)amine] has been demonstrated to act as an efficient turnover catalyst for alkane hydroxylation with m-CPBA (m-chloroperbenzoic acid), in which contribution of a NiO(+) (nickel-oxo) type active oxygen species is suggested.

The direct and conjugate shake-up cross sections for the 2p → 3p, 3s and 2s → 2p, 3s transitions are calculated for CII, NIII, OIV, FV and NeVI in a close-coupling approximation using the R-matrix method. We find that the total shake-up cross section relative to that for single photoionization decreases with increasing Z. The decrease is about a factor 10 when going from BI to NeVI. When the fu...

Covalent organic frameworks (COFs) have received broad interest owing to their permanent porosity, high stability, and tunable functionalities. COFs with long-range π-conjugation photosensitizing building blocks been explored for sustainable photocatalysis. Herein, we report the first example of COF-based energy transfer Ni catalysis. A pyrene-based COF sp2 carbon-conjugation was synthesized us...
