J Handelsman, D Ebert-May, R Beichner, P Bruns… - Science, 2004 - science.org

Research universities should provide leadership in the reform movement. Faculty and administrators should collaborate to overcome the barriers and to create an educational …

Toward new gas-analytical multisensor chips based on titanium oxide nanotube array.

Scientific reports

Fedorov F, Vasilkov M, Lashkov A, Varezhnikov A, Fuchs D, Kübel C, Bruns M, Sommer M, Sysoev V.
PMID: 28852172
Sci Rep. 2017 Aug 29;7(1):9732. doi: 10.1038/s41598-017-10495-8.

Reliable environmental monitoring requires cost effective but highly sensitive and selective gas sensors. While the sensitivity of the sensors is improved by reducing the characteristic dimensions of the gas-sensing material, the selectivity is often approached by combining the sensors...

Effects of Nonlinear Inhomogeneity on the Cosmic Expansion with Numerical Relativity.

Physical review letters

Bentivegna E, Bruni M.
PMID: 27391711
Phys Rev Lett. 2016 Jun 24;116(25):251302. doi: 10.1103/PhysRevLett.116.251302. Epub 2016 Jun 24.

We construct a three-dimensional, fully relativistic numerical model of a universe filled with an inhomogeneous pressureless fluid, starting from initial data that represent a perturbation of the Einstein-de Sitter model. We then measure the departure of the average expansion...

Proton irradiation: a key to the challenge of N-glycosidic bond formation in a prebiotic context.

Scientific reports

Saladino R, Bizzarri BM, Botta L, Šponer J, Šponer JE, Georgelin T, Jaber M, Rigaud B, Kapralov M, Timoshenko GN, Rozanov A, Krasavin E, Timperio AM, Mauro ED.
PMID: 29116184
Sci Rep. 2017 Nov 07;7(1):14709. doi: 10.1038/s41598-017-15392-8.

The formation of nucleosides in abiotic conditions is a major hurdle in origin-of-life studies. We have determined the pathway of a general reaction leading to the one-pot synthesis of ribo- and 2'-deoxy-ribonucleosides from sugars and purine nucleobases under proton...

Paralytic Shellfish Toxins and Cyanotoxins in the Mediterranean: New Data from Sardinia and Sicily (Italy).

Microorganisms

Lugliè A, Giacobbe MG, Riccardi E, Bruno M, Pigozzi S, Mariani MA, Satta CT, Stacca D, Bazzoni AM, Caddeo T, Farina P, Padedda BM, Pulina S, Sechi N, Milandri A.
PMID: 29144421
Microorganisms. 2017 Nov 16;5(4). doi: 10.3390/microorganisms5040072.

Harmful algal blooms represent a severe issue worldwide. They affect ecosystem functions and related services and goods, with consequences on human health and socio-economic activities. This study reports new data on paralytic shellfish toxins (PSTs) from Sardinia and Sicily...

Prevalence of self reported food allergy in US adults: 2001, 2006, and 2010.

Allergy and asthma proceedings

Verrill L, Bruns R, Luccioli S.
PMID: 26453587
Allergy Asthma Proc. 2015 Oct 08; doi: 10.2500/aap.2013.36.3895. Epub 2015 Oct 08.

BACKGROUND: Epidemiologic evidence indicates that food allergies are increasing in the population. Information on a change in self-reported food allergy (srFA) in adults over time is lacking.OBJECTIVE: To report the prevalence of srFA and compare differences at three time...

Parameters influencing the size of chitosan-TPP nano- and microparticles.

Scientific reports

Sreekumar S, Goycoolea FM, Moerschbacher BM, Rivera-Rodriguez GR.
PMID: 29549295
Sci Rep. 2018 Mar 16;8(1):4695. doi: 10.1038/s41598-018-23064-4.

Chitosan nanoparticles, produced by ionic gelation, are among the most intensely studied nanosystems for drug delivery. However, a lack of inter-laboratory reproducibility and a poor physicochemical understanding of the process of particle formation have been slowing their potential market...

MicroRNA-375 plays a dual role in prostate carcinogenesis.

Clinical epigenetics

Costa-Pinheiro P, Ramalho-Carvalho J, Vieira FQ, Torres-Ferreira J, Oliveira J, Gonçalves CS, Costa BM, Henrique R, Jerónimo C.
PMID: 25977730
Clin Epigenetics. 2015 Apr 10;7:42. doi: 10.1186/s13148-015-0076-2. eCollection 2015.

BACKGROUND: Prostate cancer (PCa), a highly incident and heterogeneous malignancy, mostly affects men from developed countries. Increased knowledge of the biological mechanisms underlying PCa onset and progression are critical for improved clinical management. MicroRNAs (miRNAs) deregulation is common in...

Trust, but verify: social media models for disaster management.

Disasters

Mehta AM, Bruns A, Newton J.
PMID: 27652523
Disasters. 2017 Jul;41(3):549-565. doi: 10.1111/disa.12218. Epub 2016 Sep 22.

A lack of trust in the information exchanged via social media may significantly hinder decisionmaking by community members and emergency services during disasters. The need for timely information at such times, though, challenges traditional ways of establishing trust. This...

The Surgeon's Contribution to Image-Guided Oncology.

Viszeralmedizin

Benckert C, Bruns C.
PMID: 26288021
Viszeralmedizin. 2014 Aug;30(4):232-6. doi: 10.1159/000366458.

BACKGROUND: Advances in surgical and in imaging technology permit the performance of complex tumour resections in a safe and oncologically correct manner. To date, this has mainly implicated refined preoperative imaging methods, such as three-dimensional computer-assisted planning (3D-CASP). With...

Endoscopic ultrasound in common bile duct dilatation with normal liver enzymes.

World journal of gastrointestinal endoscopy

De Angelis C, Marietti M, Bruno M, Pellicano R, Rizzetto M.
PMID: 26191344
World J Gastrointest Endosc. 2015 Jul 10;7(8):799-805. doi: 10.4253/wjge.v7.i8.799.

In recent years, the description of isolated bile duct dilatation has been increasingly observed in subjects with normal liver function tests and nonspecific abdominal symptoms, probably due to the widespread use of high-resolution imaging techniques. However, there is scant...
