Highly efficient copper(II) ion sorbents obtained by calcium carbonate mineralization on functionalized cross-linked copolymers.

Chemistry (Weinheim an der Bergstrasse, Germany)

Mihai M, Bunia I, Doroftei F, Varganici CD, Simionescu BC.
PMID: 25675892
Chemistry. 2015 Mar 23;21(13):5220-30. doi: 10.1002/chem.201406011. Epub 2015 Feb 12.

A new type of Cu(II) ion sorbents is presented. These are obtained by CaCO3 mineralization from supersaturated solutions on gel-like cross-linked polymeric beads as insoluble templates. A divinylbenzene-ethylacrylate-acrylonitrile cross-linked copolymer functionalized with weakly acidic, basic, or amphoteric functional groups...

BACKGROUND AND AIMS: The main aims of the present study were to formulate an anti-age cream based on vegetal ingredients and ferulic acid and to evaluate the physical characteristics and the efficacy of the cream.METHODS: The active ingredients were...

Recent advances in metathesis-derived polymers containing transition metals in the side chain.

Beilstein journal of organic chemistry

Dragutan I, Dragutan V, Simionescu BC, Demonceau A, Fischer H.
PMID: 26877797
Beilstein J Org Chem. 2015 Dec 28;11:2747-62. doi: 10.3762/bjoc.11.296. eCollection 2015.

This account critically surveys the field of side-chain transition metal-containing polymers as prepared by controlled living ring-opening metathesis polymerization (ROMP) of the respective metal-incorporating monomers. Ferrocene- and other metallocene-modified polymers, macromolecules including metal-carbonyl complexes, polymers tethering early or late...

Selective oxidative para C-C dimerization of 2,6-dimethylphenol.

Chemical communications (Cambridge, England)

Boldron C, Aromí G, Challa G, Gamez P, Reedijk J.
PMID: 16307153
Chem Commun (Camb). 2005 Dec 14;(46):5808-10. doi: 10.1039/b510378a. Epub 2005 Oct 28.

Mechanistic investigations on the oxidative coupling of 2,6-dimethylphenol have led to the development of a selective and efficient procedure to prepare 3,5,3',5'-tetramethyl-biphenyl-4,4'-diol, via a C-C coupling, mediated by a hypervalent form of iodine, i.e. (diacetoxyiodo)benzene and for which a...

A dramatic difference between the electron-driven dissociation of alcohols and ethers and its relation to Rydberg states.

Physical chemistry chemical physics : PCCP

Ibănescu BC, Allan M.
PMID: 18728865
Phys Chem Chem Phys. 2008 Sep 14;10(34):5232-7. doi: 10.1039/b806578k. Epub 2008 Jun 30.

A difference was observed in the reactivity of alcohols and ethers toward free electrons. Whereas the lowest core-excited state of the negative ion-a 2(n,3s2) Feshbach resonance-of the alcohols readily dissociates by losing a hydrogen atom, ethers show no observable...

Rarity of Somatic Mutation and Frequency of Normal Sequence Variation Detected in Sporadic Colon Adenocarcinoma Using High-Throughput cDNA Sequencing.

Bioinformatics and biology insights

PMID: 18389087
Bioinform Biol Insights. 2007;1:1-16.

We performed high-throughput cDNA sequencing in colorectal adenocarcinoma and matching normal colorectal epithelium. All six hundred three genes in the UCSC database that were expressed in colon cancers and contained open reading frames of 1000 nucleotides or less were...

Localization of BRCA1 protein in breast cancer tissue and cell lines with mutations.

Cancer cell international

Tulchin N, Ornstein L, Dikman S, Strauchen J, Jaffer S, Nagi C, Bleiweiss I, Kornreich R, Edelmann L, Brown K, Bodian C, Nair VD, Chambon M, Woods NT, Monteiro AN.
PMID: 23855721
Cancer Cell Int. 2013 Jul 15;13(1):70. doi: 10.1186/1475-2867-13-70.

BACKGROUND: The breast and ovarian cancer susceptibility gene (BRCA1) encodes a tumor suppressor. The BRCA1 protein is found primarily in cell nuclei and plays an important role in the DNA damage response and transcriptional regulation. Deficiencies in DNA repair...

Sialyl-tn antigen expression in Crohn's colitis.

Inflammatory bowel diseases

Ta A, Harpaz N, Bodian C, Roston A, Oberman L, Chen A, Itzkowitz S.
PMID: 23282871
Inflamm Bowel Dis. 1997;3(4):254-9.

SUMMARY: : Expression of the mucin-associated sialyl-Tn (STn) antigen is correlated with malignant progression in the colon. In patients with longstanding ulcerative colitis (UC) who never exhibited colonic dysplasia, STn was expressed in fewer than 15% of nondysplastic surveillance...

Out-of-water constitutional self-organization of chitosan-cinnamaldehyde dynagels.

Chemistry (Weinheim an der Bergstrasse, Germany)

Marin L, Moraru S, Popescu MC, Nicolescu A, Zgardan C, Simionescu BC, Barboiu M.
PMID: 24616034
Chemistry. 2014 Apr 14;20(16):4814-21. doi: 10.1002/chem.201304714. Epub 2014 Mar 11.

An investigation of the constitutional adaptive gelation process of chitosan/cinnamaldehyde (C/Cy) dynagels is reported. These gels generate timely variant macroscopic organization across extended scales. In the first stage, imine-bond formation takes place "in-water" and generates low-ordered hydrogels. The progressive...
