Scientific reports

Fina I, Apachitei G, Preziosi D, Deniz H, Kriegner D, Marti X, Alexe M.
PMID: 26403693
Sci Rep. 2015 Sep 25;5:14367. doi: 10.1038/srep14367.

Silicon has persevered as the primary substrate of microelectronics during last decades. During last years, it has been gradually embracing the integration of ferroelectricity and ferromagnetism. The successful incorporation of these two functionalities to silicon has delivered the desired...

Tailoring the surface of ZnO nanorods into corrugated nanorods via a selective chemical etch method.

Nanotechnology

Duan X, Chen G, Li C, Yin Y, Jin W, Guo L, Ye H, Zhu Y, Wu Y.
PMID: 27276661
Nanotechnology. 2016 Jul 22;27(29):295601. doi: 10.1088/0957-4484/27/29/295601. Epub 2016 Jun 08.

Using the chemical vapour deposition method, we successfully converted smooth ZnO nanorods (NRs) into corrugated NRs by simply increasing the reaction time. The surface morphology and crystallographic structure of the corrugated NRs were investigated. The corrugated NRs were decorated...

Enhancement of radiosensitization by metal-based nanoparticles in cancer radiation therapy.

Cancer biology & medicine

Su XY, Liu PD, Wu H, Gu N.
PMID: 25009750
Cancer Biol Med. 2014 Jun;11(2):86-91. doi: 10.7497/j.issn.2095-3941.2014.02.003.

Radiation therapy performs an important function in cancer treatment. However, resistance of tumor cells to radiation therapy still remains a serious concern, so the study of radiosensitizers has emerged as a persistent hotspot in radiation oncology. Along with the...

Ypt/Rab GTPases regulate two intersections of the secretory and the endosomal/lysosomal pathways.

Cellular logistics

Lipatova Z, Segev N.
PMID: 25610722
Cell Logist. 2014 Jul 03;4(3):e954870. doi: 10.4161/21592780.2014.954870. eCollection 2014.

A prevailing question in the Ypt/Rab field is whether these conserved GTPases are specific to cellular compartments. The established role for Ypt1 and its human homolog Rab1 is in endoplasmic reticulum (ER)-to-Golgi transport. More recently these regulators were implicated...

Chameleon-Inspired Mechanochromic Photonic Films Composed of Non-Close-Packed Colloidal Arrays.

ACS nano

Lee GH, Choi TM, Kim B, Han SH, Lee JM, Kim SH.
PMID: 29095594
ACS Nano. 2017 Nov 28;11(11):11350-11357. doi: 10.1021/acsnano.7b05885. Epub 2017 Nov 08.

Chameleons use a non-close-packed array of guanine nanocrystals in iridophores to develop and tune skin colors in the full visible range. Inspired by the biological process uncovered in panther chameleons, we designed photonic films containing a non-close-packed face-centered-cubic array...

Septin remodeling is essential for the formation of cell membrane protrusions (microtentacles) in detached tumor cells.

Oncotarget

Østevold K, Meléndez AV, Lehmann F, Schmidt G, Aktories K, Schwan C.
PMID: 29100341
Oncotarget. 2017 Sep 11;8(44):76686-76698. doi: 10.18632/oncotarget.20805. eCollection 2017 Sep 29.

Microtentacles are mostly microtubule-based cell protrusions that are formed by detached tumor cells. Here, we report that the formation of tumor cell microtentacles depends on the presence and dynamics of guanine nucleotide-binding proteins of the septin family, which are...

The role of alkali metal cations in the stabilization of guanine quadruplexes: why K(+) is the best.

Physical chemistry chemical physics : PCCP

Zaccaria F, Paragi G, Fonseca Guerra C.
PMID: 27185388
Phys Chem Chem Phys. 2016 Aug 21;18(31):20895-904. doi: 10.1039/c6cp01030j. Epub 2016 May 17.

The alkali metal ion affinity of guanine quadruplexes has been studied using dispersion-corrected density functional theory (DFT-D). We have done computational investigations in aqueous solution that mimics artificial supramolecular conditions where guanine bases assemble into stacked quartets as well...

A direct dynamics study of the deprotonated guanine·cytosine base pair: intra-base pair proton transfer, thermal dissociation vs. collision-induced dissociation, and comparison with experiment.

Physical chemistry chemical physics : PCCP

Liu J.
PMID: 29115359
Phys Chem Chem Phys. 2017 Nov 22;19(45):30616-30626. doi: 10.1039/c7cp06124b.

Direct dynamics trajectories were calculated at the B3LYP/6-31G* level of theory to examine the intra-base pair proton transfer and dissociation of the deprotonated guanine (G)·cytosine (C) base pair under different excitation conditions, and to explore the origin of the...

Self-injurious Behavior in a Young Child with Lesch-Nyhan Syndrome.

Indian journal of psychological medicine

Mohapatra S, Sahoo AJ.
PMID: 27833236
Indian J Psychol Med. 2016 Sep-Oct;38(5):477-479. doi: 10.4103/0253-7176.191389.

Lesch-Nyhan syndrome (LNS) is a rare inherited disorder caused by a deficiency of the enzyme hypoxanthine-guanine phosphoribosyl transferase-1. Few reports on behavioral aspects especially self-injurious behavior in LNS patients are available. We report a case of LNS in an...

Surface Adsorption from the Exchange-Hole Dipole Moment Dispersion Model.

Journal of chemical theory and computation

Christian MS, Otero-de-la-Roza A, Johnson ER.
PMID: 27253340
J Chem Theory Comput. 2016 Jul 12;12(7):3305-15. doi: 10.1021/acs.jctc.6b00222. Epub 2016 Jun 14.

The accurate calculation of intermolecular interaction energies with density functional theory requires methods that include a treatment of long-range, nonlocal dispersion correlation. In this work, we explore the ability of the exchange-hole dipole moment (XDM) dispersion correction to model...

Human Antibody Fusion Proteins/Antibody Drug Conjugates in Breast and Ovarian Cancer.

Transfusion medicine and hemotherapy : offizielles Organ der Deutschen Gesellschaft fur Transfusionsmedizin und Immunhamatologie

Padayachee ER, Biteghe FAN, Malindi Z, Bauerschlag D, Barth S.
PMID: 29070975
Transfus Med Hemother. 2017 Sep;44(5):303-310. doi: 10.1159/000479979. Epub 2017 Sep 11.

Considerable research efforts have been dedicated to understanding ovarian and breast cancer mechanisms, but there has been little progress translating the research into effective clinical applications. Hence, personalized/precision medicine has emerged because of its potential to improve the accuracy...

Molecular Recognition of Platinated DNA from Chromosomal HMGB1.

Journal of chemical theory and computation

Nguyen TH, Rossetti G, Arnesano F, Ippoliti E, Natile G, Carloni P.
PMID: 26588321
J Chem Theory Comput. 2014 Aug 12;10(8):3578-84. doi: 10.1021/ct500402e. Epub 2014 Jul 10.

Cisplatin cures testicular and ovarian cancers with unprecedented potency. It induces its beneficial activity by covalently binding to DNA. Repair enzymes, which remove the platinated lesions from DNA, cause drug resistance. Chromosomal High Mobility Group Box proteins (HMGB) may...
