… The major contemporary applications of kifunensine stem from its activity as a specific inhibitor of the class I GH47 α-mannosidases involved in glycoprotein biosynthesis within the …

"Bath Salts" intoxication with multiorgan failure and left-sided ischemic colitis: a case report.

Hippokratia

Gavriilidis G, Kyriakoudi A, Tiniakos D, Rovina N, Koutsoukou A.
PMID: 27703310
Hippokratia. 2015 Oct-Dec;19(4):363-365.

BACKGROUND: In the recent years, a new group of designer drugs, under the brand name of bath salts has emerged as a new trend. They are mainly b-ketone amphetamine analogs and are derivatives of cathinone, a monoamine alkaloid. They...

How do Water Solvent and Glutathione Ligands Affect the Structure and Electronic Properties of Au25(SR)18(-)?.

The journal of physical chemistry letters

Rojas-Cervellera V, Rovira C, Akola J.
PMID: 26722882
J Phys Chem Lett. 2015 Oct 01;6(19):3859-65. doi: 10.1021/acs.jpclett.5b01382. Epub 2015 Sep 15.

The effects of aqueous solvent and biological ligands on the structural and electronic properties of thiolate-protected Au25(SR)18(-) clusters have been studied by performing quantum mechanics/molecular mechanics (QM/MM) simulations. Analysis of bond distances and angles show that the solvated nanocluster...

Chronic Myeloid Leukemia and Hepatoblastoma: Two Cancer Models to Link Metabolism to Stem Cells.

Frontiers in oncology

Cipolleschi MG, Marzi I, Rovida E, Dello Sbarba P.
PMID: 27148487
Front Oncol. 2016 Apr 14;6:95. doi: 10.3389/fonc.2016.00095. eCollection 2016.

Low oxygen tension is a critical aspect of the stem cell niche where stem cells are long-term maintained. In "physiologically hypoxic" stem cell niches, low oxygen tension restrains the clonal expansion of stem cells without blocking their cycling, thereby...

Antibiotic prophylaxis in thyroid surgery.

Gland surgery

Fachinetti A, Chiappa C, Arlant V, Kim HY, Liu X, Sun H, Dionigi G, Rovera F.
PMID: 29142844
Gland Surg. 2017 Oct;6(5):525-529. doi: 10.21037/gs.2017.07.02.

Use of antibiotic prophylactic (AP) in clean surgery is still controversial. We reviewed the literature of the last 10 years to identify the best way to approach the use of prophylactic antibiotic in thyroid surgery. In thyroid surgery, it...

Therapeutic exercise in improving acute lung injury: a long distance to be covered.

Interanionic (-)O-H...O(-) interactions: a solid-state and computational study of the ring and chain motifs.

Chemistry (Weinheim an der Bergstrasse, Germany)

Braga D, Maini L, Grepioni F, Mota F, Rovira C, Novoa JJ.
PMID: 11192087
Chemistry. 2000 Dec 15;6(24):4536-51. doi: 10.1002/1521-3765(20001215)6:24<4536::aid-chem4536>3.0.co;2-m.

The (-)O-H...O(-) interaction formed by the anions HCO3-, HCO4, HC4O4 and HC5O5- (HA-), obtained upon monodeprotonation of the corresponding carbonic, oxalic, squaric and croconic acids (H2A), has been investigated theoretically and experimentally. The ring (RING) and chain (CHAIN) hydrogen...

A new valence tautomerism example in an electroactive ferrocene substituted triphenylmethyl radical.

Journal of the American Chemical Society

Ratera I, Ruiz-Molina D, Renz F, Ensling J, Wurst K, Rovira C, Gütlich P, Veciana J.
PMID: 12568590
J Am Chem Soc. 2003 Feb 12;125(6):1462-3. doi: 10.1021/ja0282590.

A new molecular system combining an open-shell organic radical that acts as an acceptor group, different from an o-quinone moiety, covalently linked to a ferrocene moiety, acting as the donor group, is shown to exhibit valence tautomerism.

Protonation state of the equatorial ligands and dynamics of the OH...O units in a cobaloxime biomimetic.

Inorganic chemistry

Rovira C, Kunc K, Parrinello M.
PMID: 12206709
Inorg Chem. 2002 Sep 09;41(18):4810-4. doi: 10.1021/ic025583n.

The protonation state of the dimethylglyoxime ligands in the B(12) coenzyme biomimetic [Co(CCl=CHCl)(dmgH)(2)(py)].CHCl(3) was investigated by using first-principles molecular dynamics. Our simulations at 173 and 300 K reveal that one of the oxime protons remains bonded to a nitroxyl...

Synthesis, separation, and isomer-dependent packing in two dimensions--detected by scanning tunnelling microscopy--of a TTF derivative.
