Sirolimus‐ versus paclitaxel‐eluting stents for coronary bifurcations intervention
Authors: Qian Juying , Chen Zhangwei , Ma Jianying , Ge Junbo 
Published: November 2011

AbstractBackgrounds: Relative efficacy and safety of sirolimus‐eluting stents (SES) compared with paclitaxel‐eluting stents (PES) remains controversial. It is unknown whether there are different effect and safety in coronary bifurcation treatment between SES and PES. Objectives: The meta‐analysis was performed to compare the clinical outcomes of SES and PES in coronary bifurcation intervention. Methods: Five head‐to‐head clinical trials of SES versus PES in coronary bifurcation intervention were included. A total of 2,567 patients were involved in the meta‐analysis. Mean follow‐up period ranged from 6 to 35 months. The primary end points were the need for target lesion revascularization (TLR) and main‐branch restenosis. Secondary end points were target vessel revascularization (TVR), cardiac death, major adverse cardiac events (MACE), and stent thrombosis. Results: Compared with PES, SES significantly reduced the risk of TLR (5.3% vs. 10.6%, odds ratio (OR) 0.52; 95% confidence interval (CI) = 0.38–0.70, P < 0.001), main‐branch restenosis (4.59% vs. 12.59%, OR 0.31; 95% CI = 0.18–0.55, P < 0.001) and TVR (7.05% vs. 12.57%, OR 0.58; 95% CI = 0.42–0.81, P = 0.001) in coronary bifurcation intervention. In addition, SES group also had a significantly lower incidence of MACE (8.20% vs. 14.13%, OR 0.58; 95% CI = 0.40–0.84, P = 0.004) than PES group. However, there were no statistical difference with respect to the incidence of cardiac death (1.64% vs. 1.09%, P = 0.19) and stent thrombosis (0.84% vs. 1.08%, P = 0.64) between SES and PES groups. Conclusions: Compared with PES, SES reduced the incidence of TLR, main‐branch restenosis and MACE in coronary bifurcation intervention, while the risk of stent thrombosis was similar between SES and PES groups. © 2011 Wiley Periodicals, Inc.
Red‐Emitting Dyes with Photophysical and Photochemical Properties Controlled by pH

AbstractNew unsymmetrical zinc azaphthalocyanines, bearing one substituted aniline as a peripheral substituent, were prepared by using a statistical condensation approach. Both fluorescence and singlet oxygen quantum yields were extremely low in DMF (ΦF<0.01, ΦΔ<0.02, respectively), but increased after the addition of sulfuric acid, reaching values comparable to controls without aniline substituents (ΦF=0.22–0.29, ΦΔ=0.40–0.59, respectively). This behavior was attributed to the deactivation of excited states by intramolecular charge transfer from a donor site (aniline), which was blocked after protonation in acidic media. In the protonated form, all of the compounds efficiently emitted light with λem in the region of 662–675 nm. The investigated compounds were anchored to dioleoylphosphatidylcholine (DOPC) unilamellar vesicles and showed response to buffer pH. They were highly fluorescent at low pH values and almost nonfluorescent in neutral solutions. The pKa values were determined in DOPC vesicles and ranged between 2.2 and 4.2.

Published: November 2011

AbstractA new type of host compound (1), tetraphenyl zinc–porphyrin (ZnTPP) that contains four triazole groups at the ortho‐position of each phenyl group, has been synthesized and characterized by using 1H, 13C NMR, and MALDI‐TOF‐MS analyses. The host–guest complex formation between 1 and halides was investigated by using 1H NMR spectroscopy in [D6]DMSO. The triazole, benzyl, and phenylene proton signals were shifted upfield by the addition of halides in the form of tetrabutylammonium salts, which implies that the triazole protons in 1 are allocated very closely to the porphyrin ring and are directed toward the binding pocket over the porphyrin ring during the formation of hydrogen bonds. The UV/Vis absorption spectra showed that both the Soret and Q band absorptions of 1 underwent a strong redshift due to the addition of halides. Compound 1 exhibited surprisingly strong binding affinities for the halides, where the association constants for Cl−, Br−, and I− binding were estimated to be larger than 108, 1.79×107, and 1.84×105 M−1, respectively. The UV/Vis absorption changes and the result of competitive titration using 4‐tert‐butylpyridine indicated that the cooperative effects of axial coordination and CH⋅⋅⋅X hydrogen bond interactions resulted in the strong binding affinity of 1 to halides.

AbstractResponding to growing concerns regarding the safety, quality, and efficacy of cancer care in the United States, the Institute of Medicine (IOM) of the National Academy of Sciences commissioned a comprehensive review of cancer care delivery in the US health care system in the late 1990s. The National Cancer Policy Board (NCPB), a 20‐member board with broad representation, performed this review. In its review, the NCPB focused on the state of cancer care delivery at that time, its shortcomings, and ways to measure and improve the quality of cancer care. The NCPB described an ideal cancer care system in which patients would have equitable access to coordinated, guideline‐based care and novel therapies throughout the course of their disease. In 1999, the IOM published the results of this review in its influential report, Ensuring Quality Cancer Care. The report outlined 10 recommendations, which, when implemented, would: 1) improve the quality of cancer care, 2) increase the current understanding of quality cancer care, and 3) reduce or eliminate access barriers to quality cancer care. Despite the fervor generated by this report, there are lingering doubts regarding the safety and quality of cancer care in the United States today. Increased awareness of medical errors and barriers to quality care, coupled with escalating health care costs, has prompted national efforts to reform the health care system. These efforts by health care providers and policymakers should bridge the gap between the ideal state described in Ensuring Quality Cancer Care and the current state of cancer care in the United States.

Cryptanalysis of an efficient three‐party password‐based key exchange scheme
Authors: Simplicio Marcos A. , Sakuragui Rony R.M. 
Published: November 2011

SUMMARYThree‐party password‐authenticated key exchange (3PAKE) protocols allow entities to negotiate a secret session key with the aid of a trusted server with whom they share a human‐memorable password. Recently, Lou and Huang proposed a simple 3PAKE protocol based on elliptic curve cryptography, which is claimed to be secure and to provide superior efficiency when compared with similar‐purpose solutions. In this paper, however, we show that the solution is vulnerable to key‐compromise impersonation and offline password guessing attacks from system insiders or outsiders, which indicates that the empirical approach used to evaluate the scheme's security is flawed. These results highlight the need of employing provable security approaches when designing and analyzing PAKE schemes. Copyright © 2011 John Wiley & Sons, Ltd.
Assessment of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) status in the fine needle aspirates of metastatic breast carcinomas

AbstractThe assessment of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor (HER2) status in the fine needle aspirates of metastatic breast carcinomas has prognostic and therapeutic implications. In this study, expression of ER, PR, and HER2 was assessed by immunohistochemical study in 70 cases of metastatic breast carcinomas and HER2 gene amplification was further evaluated by fluorescence in situ hybridization (FISH) in 38 (54%) cases. Positive expression of ER and PR was seen in 42 (60%) and 16 (23%) cases of metastatic breast carcinomas, respectively. HER2 immunoreactivity was scored as 0/1+ in 39 (56%), 2+ in 10 (14%), and 3+ in 21 (30%) cases. HER2 gene amplification was seen in 20% of HER2 2+ and 64% of HER2 3+ cases. ER, PR, and HER2 status in primary breast cancers were available to comparison in 31 cases (44%). The concordance rates between metastatic and primary breast carcinomas were 81% for ER, 65% for PR and 71% for HER2. Our study demonstrates that ER, PR, and HER2 status can be assessed in the fine needle aspirates of metastatic breast carcinomas and ER has a higher concordance rate between metastatic and primary breast carcinomas than PR and HER2. The addition of HER2 gene amplification FISH test helps in accurate assessment of HER2 status in metastatic breast carcinomas. Diagn. Cytopathol. 2013;41:308–315. © 2011 Wiley Periodicals, Inc.
Iron(II)‐Mediated Reductive Cleavage of Disulfide and Diselenide Bonds: Iron(III) Complexes of Mixed O,X,O and O,X (X = S, Se) Donor Ligands

AbstractThe syntheses and characterization of a methoxo‐bridged diiron(III) complex, [Fe2LSe2(μ‐OCH3)2(CH3OH)2] (1), and three mononuclear iron(III) complexes Bu4N[FeLSe2] (2), Bu4N[FeLSe′LSe] (3) and Bu4N[FeLS′LS] (4) [H2LSe = 2,2′‐selenobis(4,6‐di‐tert‐butylphenol), H2LS = 2,2′‐thiobis(4,6‐di‐tert‐butylphenol), H2LSe′ = 3,5‐di‐tert‐butyl‐2‐hydroxyselenophenol, and H2LS′ = 3,5‐di‐tert‐butyl‐2‐hydroxythiophenol] are discussed. The single crystal structure of 1·7CH3OH, as determined by XRD, reveals an asymmetric Fe2O2 core in which the two iron and two methoxo oxygen atoms constitute a perfect planar atomic arrangement. Complex 1 exhibits a moderate antiferromagnetic exchange coupling (J = –13.2 cm–1) that operates between the two high spin iron(III) centers (SFe = 2.5) with a resulting St = 0 ground state, while 2 is a six coordinate mononuclear high spin iron(III) complex. The mixed ligand complexes 3 and 4 are formed during the reaction of a tridentate O,X,O ligand (X = S, Se) with iron(II) salts in the presence of either the H2LSe–Se or H2LS–S ligand [H2LSe–Se = 2,2′‐diselenobis(4,6‐di‐tert‐butylphenol), and H2LS–S = 2,2′‐dithiobis(4,6‐di‐tert‐butylphenol)] in an inert atmosphere, whereby iron(II) is oxidized to iron(III) and the disulfide or diselenide bonds are reductively cleaved. The temperature‐independent magnetic moment values of 3 and 4 indicate that the complexes contain mononuclear high spin iron(III) centers. The crystal structure of 3 confirms that a reductive Se–Se bond cleavage with concomitant formation of a five coordinate trigonal bipyramidal anionic iron(III) complex, [FeLSe′LSe]–, has occurred. It is proposed that the iron(II) ions take part in the electron‐transfer reaction associated with the reductive cleavage of the disulfide and diselenide bonds.
