Ribosomes and marrow failure: coincidental association or molecular paradigm?
Authors: Liu Johnson M. , Ellis Steven R. 
Published: March 2006

AbstractGene products mutated in the inherited bone marrow failure syndromes dyskeratosis congenita (DC), cartilage-hair hypoplasia (CHH), Diamond-Blackfan anemia (DBA), and Shwachman-Diamond syndrome (SDS) are all predicted to be involved in different aspects of ribosome synthesis. At this moment, however, it is unclear whether this link indicates a causal relationship. Although defective ribosome synthesis may contribute to each of these bone marrow failure syndromes (and perhaps others), precisely which feature of each disease is a consequence of failure to produce adequate amounts of ribosomes is obscured by the tendency of each gene product to have extraribosomal functions. Delineation of the precise role of each gene product in ribosomal biogenesis and in hematopoietic development may have both therapeutic and prognostic importance and perhaps even direct the search for new bone marrow failure genes.
Growth Hormone Treatment and Aortic Dimensions in Turner Syndrome
Authors: Bondy Carolyn A. , Van Phillip L. , Bakalov Vladimir K. , Ho Vincent B. 
Published: March 2006

Background: In recent years many girls with Turner syndrome (TS) have been treated with supraphysiological doses of GH to increase adult height. In addition to promoting statural growth, GH may have direct effects on the cardiovascular system.
Objective: We sought to determine whether GH treatment affects aortic diameter in girls with TS because there is an increased risk for aortic dilation and dissection in this syndrome.
Methods: In a retrospective, cross-sectional study, we compared ascending and descending aortic diameters measured by magnetic resonance imaging in GH-treated (n = 53) vs. untreated (n = 48) patients with TS participating in a National Institutes of Health protocol between 2001 and 2004.
Results: The average duration of GH treatment was 4.7 with se 0.4 yr (range 2–11 yr). The two groups were similar in age and weight, but GH-treated subjects were on average 8 cm taller (P = 0.002). The diameter of the ascending aorta was increased by 7.3% and descending aorta by 8.9% in the GH-treated group. However, after correction for age, height, weight, and presence of bicuspid aortic valve and coarctation, using a multiple regression, neither history of GH treatment nor the length of GH treatment had an effect on the aortic diameter. Weight (P = 0.02), height (P = 0.001), and presence of bicuspid aortic valve (P = 0.0001) were associated with larger ascending aortic diameter, whereas age (P = 0.008), height (P = 0.02), and history of coarctation (P = 0.006) were associated with larger descending aortic diameter.
Conclusions: GH treatment of girls with TS does not seem to affect ascending or descending aortic diameter above the increase related to the larger body size.

Light- and Heat-Induced Geometric Isomerization of Chloro(hydrido)iridium(III) Complex Containing a (2-Phosphinoethyl)silyl Chelate Ligand
Authors: Okazaki Masaaki , Kawano Yasuro , Tobita Hiromi , Inomata Shinji , Ogino Hiroshi 
Published: March 2006

Abstract
Photolysis of chloro(hydrido)(silyl)iridium complex [Ir(Cl)(H){HMesSi(CH2)2PPh2}(PMe3)2] (1) caused the geometric isomerization to 2 which reached to a photostationary state with the ratio of 1 : 2 = 29 :71. Both 1 and 2 take mer configuration, but 1 has a hydrido ligand opposite to one of PMe3’s while 2 has that opposite to the PPh2. On thermolysis, 2 reverted to 1 quantitatively.

Published: March 2006

Abstract
The kinetics of the electron-transfer reaction between [VO{3-MeOsal-(RR) or (SS)-chxn}] and [VO{sal-(RR)-chxn}]+ were studied using the stopped-flow method in acetonitrile over the temperature range of 5 – 25 °C. The reactions were enantioselective. The ratio of the rate constant of the electron-transfer between [VO{3-MeOsal-(SS)-chxn}] and [VO{sal-(RR)-chxn}]+ (kSS-RR) and that between [VO{3-MeOsal-(RR)-chxn}] and [VO{sal-(RR)-chxn}]+ (kRR-RR) was 2.0 (kSS-RR / kRR-RR) at 25 °C.

Published: March 2006

Abstract
The first example of the palladium-catalyzed asymmetric nucleophilic substitutions of chiral β-sulfinylallylic systems is described. The degree of the asymmetric induction was dependent on the reaction conditions, especially a phosphine ligand used. The plausible mechanism of the asymmetric induction is proposed on the basis of the stereochemical results obtained.

Authors: Fujita Morifumi , Ishida Akito , Majima Tetsuro , Fukuzumi Shunichi , Takamuku Setsuo 
Published: March 2006

Abstract
Photoinduced hydride reduction of 10-methylacridinium ion (AcrH+) by alkylbenzene occurs to yield 10-methyl-9,10-dihydroacridine in the presence of perchloric acid, while photoaddition occurs to yield 9-alkyl-10-methyl-9,10-dihydroacridine in the absence of perchloric acid. The hydride reduction of AcrH+ in the presence of perchloric acid proceeds via protonation of acridinyl radical produced by photoinduced electron transfer from alkylbenzene.

Published: March 2006

Abstract
Substituted 1,4-dicyanobenzenes are prepared as electron-accepting photosensitizers. The efficiency of some photosensitized reactions is influenced remarkably by the substituent(s) of 1,4-dicyanobenzene. By using mono or dimethylated dicyanobenzene, the reactions proceed more rapidly as compared with that by using 1,4-dicyanobenzene itself.

Thermal [3+2] cycloaddition of C60 with α-silylamine derivatives proceeds smoothly under neutral conditions to afford fullerene-fused pyrrolidines and 1-pyrrolines in moderate to good yields. The new methods are effective for constructing fullerene derivatives containing bulky aryl-substituents.
Unusual Intermolecular Short Contacts of C···C = 2.3 Å in Crystal Structure of Copper Complex of Schiff Base of Vitamin B6 Phosphate Ester; Does It Reveal an Intermediate Structure to σ-Covalent Bond Formation ?
Authors: Ishida Toshimasa , In Yasuko , Nagata Hiroomi , Doi Mitsunobu , Wakahara Akio 
Published: March 2006

Abstract
The crystal structure of copper complex of Schiff base of pyridoxal-5-phosphate and pyridoxamine-5-phosphate showed the strikingly short intermolecular C···C contact of ∼ 2.3 Å. Since this value corresponds just to a transition state for cycloaddition reaction estimated by ab initio calculation, the present result may be the first structural presentation of an intermediate structure from the noncovalent π–π interaction to the σ-covalent bond formation.

Published: March 2006

Abstract
Network polysilanes with various substituents have been prepared by a disproportionation reaction of 1,1,2,2-tetraethoxy-1,2-dimethyldisilane with a small amount of organolithium reagents. Aromatic dilithio compounds lead to incorporation of aromatic bridges into the network polysilanes, which show relatively higher electroconductivity by iodine doping. It seems that lithium ethoxide catalyzes the polymerization.

Abstract
The activation energy for the C(5)-N(1) bond homolysis in the lowest excited singlet state of the 1-Phenyl, 3-Aryl, 5-(2′Phenylethenyl) Δ2-pyrazolines as deduced from the temperature dependence of the fluorescence quantum yield (ΦF) can be combined with the corresponding singlet energy to give a constant value of 75.5 kcal mol−1 as the total photofission energy. The corresponding value for 1,3-Diphenyl, 5-(2′-Iodo phenyl) Δ2-pyrazoline significantly exceeds the bond dissociation energy (BDE) of the aryl carbon-iodine linkage.

Published: March 2006

Abstract
It was observed that surface-enhanced Raman scattering (SERS) spectra of p-nitrothiophenol (PNTP) self-assembled monolayer adsorbed on a smooth silver electrode changed by laser light irradiation. The SERS spectra were identical with those of p-aminothiophenol (PATP). This reaction proceeded even at the electrode potential where PNTP was electrochemically stable under dark. It was found that photoinduced reduction of PNTP occurred on a smooth silver electrode surface.
