Clonal chromosome-aberrations in fibrocystic breast disease-associated with increased risk of cancer.

International journal of oncology

Petersson C, Johansson B, Pandis N, Gorunova L, Ingvar C, Idvall I, Mandahl N, Mitelman F.
PMID: 21559699
Int J Oncol. 1994 Dec;5(6):1207-10. doi: 10.3892/ijo.5.6.1207.

Short-term cultures of 29 samples of fibrocystic breast disease were cytogenetically analyzed. Clonal chromosome aberrations were found in six specimens, whereas the remaining 23 had a normal karyotype. Three of the abnormal samples displayed karyotypic anomalies previously associated with...

1D CdS/PbS heterostructured nanowire synthesis using cation exchange.

Chemical communications (Cambridge, England)

Mukherjee B, Peterson A, Subramanian VR.
PMID: 22274619
Chem Commun (Camb). 2012 Feb 28;48(18):2415-7. doi: 10.1039/c2cc16254g. Epub 2012 Jan 25.

Heterostructured CdS nanowires with PbS deposits forming p-n junctions have been synthesized by successive cation exchange. The method developed herein opens up the possibility of preparing a spatially distributed heterojunction-based multifunctional electrode. The (photo)electrochemical activity of the material may...

Migrating bullet: A case of a bullet embolism to the pulmonary artery with secondary pulmonary infarction after gunshot wound to the left globe.

Journal of emergencies, trauma, and shock

Duke E, Peterson AA, Erly WK.
PMID: 24550629
J Emerg Trauma Shock. 2014 Jan;7(1):38-40. doi: 10.4103/0974-2700.125638.

Bullet embolism is a rare phenomenon following gunshot injuries. We present a case of a 25-year-old male who sustained a gunshot wound to his left globe with the bullet initially lodged in his right transverse sinus. The bullet ultimately...

Intracerebral metaplastic meningioma with prominent ossification and extensive calcification.

Rare tumors

Huang J, Petersson F.
PMID: 21769319
Rare Tumors. 2011 Apr 04;3(2):e20. doi: 10.4081/rt.2011.e20.

We present a patient (male 26 years) with a short history of recurrent seizures induced by a largely intracerebrally located frontal lobe meningioma. The tumor displayed a heretofore unpublished combination of extensive metaplastic bone formation and prominent non-psammomatous calcifications...

Multi-mode photonic crystal fibers for VCSEL based data transmission.

Optics express

Mortensen N, Stach M, Broeng J, Petersson A, Simonsen H, Michalzik R.
PMID: 19466080
Opt Express. 2003 Aug 25;11(17):1953-9. doi: 10.1364/oe.11.001953.

Quasi error-free 10Gbit/s data transmission is demonstrated over a novel type of 50 microm core diameter photonic crystal fi ber with as much as 100m length. Combined with 850 nm VCSEL sources, this fi ber is an attractive alternative...

Neurobehavioral Mechanisms of Traumatic Stress in Post-traumatic Stress Disorder.

Current topics in behavioral neurosciences

Lapiz-Bluhm MD, Peterson AL.
PMID: 24691656
Curr Top Behav Neurosci. 2014;18:161-90. doi: 10.1007/7854_2014_307.

Post-traumatic stress disorder (PTSD) is a debilitating psychiatric disorder that develops following trauma exposure. It is characterized by four symptom clusters: intrusion, avoidance, negative alteration in cognitions and mood, and alterations in arousal and reactivity. Several risk factors have...

Evaluation of the heats of formation of corannulene and C60 by means of inexpensive theoretical procedures.

The journal of physical chemistry. A

Dobek FJ, Ranasinghe DS, Throssell K, Petersson GA.
PMID: 23675698
J Phys Chem A. 2013 Jun 06;117(22):4726-30. doi: 10.1021/jp404158v. Epub 2013 May 28.

Inexpensive ab initio procedures that employ homologous sequences of isodesmic reactions for the calculation of enthalpies of formation of moderate-sized organic molecules were tested with benzene, naphthalene, phenanthrene, and triphenylene. Two size-consistent adjustable parameters were found to bring the...

Stress and symptoms of depression among medical students at the University of Copenhagen.

Scandinavian journal of public health

Haldorsen H, Bak NH, Dissing A, Petersson B.

Scand J Public Health. 2014 Feb;42(1):89-95. doi: 10.1177/1403494813503055. Epub 2013 Sep 02.

OBJECTIVE: This article aims to assess the levels of stress and symptoms of depression among Danish medical students, as well as explore the effect of social support on psychological distress. The results are based on numbers from the follow-up...

Note: fast and reliable fracture strain extraction technique applied to silicon at nanometer scale.

The Review of scientific instruments

Passi V, Bhaskar U, Pardoen T, Sodervall U, Nilsson B, Petersson G, Hagberg M, Raskin JP.
PMID: 22129022
Rev Sci Instrum. 2011 Nov;82(11):116106. doi: 10.1063/1.3655464.

Simple fabrication process and extraction procedure to determine the fracture strain of monocrystalline silicon are demonstrated. Nanowires/nanoribbons in silicon are fabricated and subjected to uniaxial tensile stress along the complete length of the beams. Large strains up to 5%...

Covalent incorporation of aminated nanodiamond into an epoxy polymer network.

ACS nano

Mochalin VN, Neitzel I, Etzold BJ, Peterson A, Palmese G, Gogotsi Y.

Outstanding mechanical and optical properties of diamond nanoparticles in combination with their biocompatibility have recently attracted much attention. Modification of the surface chemistry and incorporation into a polymer is required in many applications of the nanodiamond. Nanodiamond powder with...

A new method for the automated selection of the number of components for deconvolving overlapping chromatographic peaks.

Analytica chimica acta

Mathematical deconvolution methods can separate co-eluting peaks in samples for which (chromatographic) separation fail. However, these methods often heavily rely on manual user-input and interpretation. This is not only time-consuming but also error-prone and automation is needed if such...
