Histological and molecular structure characterization of annular collagen after intradiskal electrothermal annuloplasty.

HSS journal : the musculoskeletal journal of Hospital for Special Surgery

Southern D, Lutz G, Bracilovic A, West P, Spevak M, Camacho NP, Doty S.
PMID: 18751846
HSS J. 2006 Feb;2(1):49-54. doi: 10.1007/s11420-005-0126-y.

The mechanism of pain relief of intradiskal electrothermal annuloplasty (IDET) in the treatment of lumbar diskogenic pain is uncertain. Theories include sealing of annular fissures via collagen denaturation and contraction. Prior studies offer conflicting qualitative data on the ability...

Imaging-related medications: a class overview.

Proceedings (Baylor University. Medical Center)

Widmark JM.
PMID: 17948119
Proc (Bayl Univ Med Cent). 2007 Oct;20(4):408-17. doi: 10.1080/08998280.2007.11928336.

Imaging-related medications (contrast agents) are commonly utilized to improve visualization of radiographic, computed tomography (CT), and magnetic resonance (MR) images. While traditional medications are used specifically for their pharmacological actions, the ideal imaging agent provides enhanced contrast with little...

Iodine based radiopacity of experimental blood clots for testing of mechanical thrombectomy devices.

Radiology and oncology

Luo ZH, Chung A, Choi G, Lin YH, Pang H, Uchida BT, Pavcnik D, Jeromel M, Keller FS, Rösch J.

BACKGROUND: Barium sulfate powder used for radiopacity of experimental blood clots (EBCs) for testing mechanical thrombectomy devices (MTD) has negative effects on EBCs mechanical properties. In vitro and in vivo exploration was performed to determine if the iodine based...

Kubelka-Munk optical properties of a barium sulfate white reflectance standard.

Applied optics

Patterson EM, Shelden CE, Stockton BH.
PMID: 20168570
Appl Opt. 1977 Mar 01;16(3):729-32. doi: 10.1364/AO.16.000729.

We have measured the Kubelka-Munk scattering and absorption coefficients for a barium sulfate white reflectance standard. These measurements have been based on measurements of the absolute reflectance for the particular barium sulfate samples whose scattering and absorption coefficients were...

Surface-enhanced Raman spectroscopy analysis of house paint and wallpaper samples from an 18th century historic property.

The Analyst

Harroun SG, Bergman J, Jablonski E, Brosseau CL.
PMID: 21267481

Conservation efforts for heritage buildings require a substantial knowledge of the chemical makeup of materials that were used throughout the lifetime of the property. In particular, conservators are often concerned with the identification of colorants used in both interior...

Fatal esophageal fibrosarcoma associated to parasitism by spirurid nematode Spirocerca lupi in a dog: a case report.

Journal of parasitic diseases : official organ of the Indian Society for Parasitology

Da Fonseca EJ, Do Amarante EE, de S Abboud LC, Hees SJ, Franco RJ, de A Silva BJ.

A 7-years-old intact female mixed breed dog was referred to the private veterinary clinic because of history of intense food regurgitation. The plain X-ray examination and the contrast-enhanced X-ray using barium sulfate revealed the presence of a radio-opaque mass...

Study of barium sulfate dissolution by scale dissolver based on solutions of DTPA.

Anais da Academia Brasileira de Ciencias

Abib GAP, Cruz GFD, Vaz Junior ASL.
PMID: 30304245

In offshore oil wells it is very common to perform seawater injection through injection wells for hydrocarbon recovery. When seawater, rich in sulfate ion, mixes with formation water, whose composition can contain divalent cations such as barium and calcium,...

Pelagic barite precipitation at micromolar ambient sulfate.

Nature communications

Horner TJ, Pryer HV, Nielsen SG, Crockford PW, Gauglitz JM, Wing BA, Ricketts RD.
PMID: 29109481
Nat Commun. 2017 Nov 07;8(1):1342. doi: 10.1038/s41467-017-01229-5.

Geochemical analyses of sedimentary barites (barium sulfates) in the geological record have yielded fundamental insights into the chemistry of the Archean environment and evolutionary origin of microbial metabolisms. However, the question of how barites were able to precipitate from...

Unveiling the Ambrotype: Characterization of Two 19th Century Photographs.

Microscopy and microanalysis : the official journal of Microscopy Society of America, Microbeam Analysis Society, Microscopical Society of Canada

Costa L, Nunes M, Costa S, Trindade M, Miguel C, Ferreira T.

This work used a multi-analytical approach to characterize two 19th century ambrotypes and was motivated by the lack of insight on these historical objects. Photographic imaging and optical microscopy (OM) were used to identify abrasions, cracks related to reticulation,...

Pulsed ultrasound for temperature control and clogging prevention in micro-reactors.

Ultrasonics sonochemistry

Delacour C, Lutz C, Kuhn S.
