Isoniazid Levels in the Bronchoalveolar Lavage Fluid of Patients with Pulmonary Tuberculosis

Autor: Timothy J. Harkin, M. E. Doerfler, J. K. O'Brien, William N. Rom

Publikováno v: Lung. 176:205-211

Isoniazid (INH) is one of the most important first line drugs in the treatment of tuberculosis. We utilized high performance liquid chromatography with a hydrazone extraction technique to measure INH in bronchoalveolar lavage (BAL) fluid specimens fr

Tendonitis of the deep digital flexor tendon in the distal metacarpal/metatarsal region associated with tenosynovitis of the digital sheath in the horse

Autor: Sue J. Dyson, J. K. O'brien, Alistair Barr, Frances J. Barr

Publikováno v: Europe PubMed Central

Twenty-four horses with ultrasonographic evidence of tendonitis of the deep digital flexor tendon in the metacarpal/metatarsal region were seen over a 7 year period. Most horses had mild to moderate lameness and distension of the digital flexor tendo

The Value of Ex Situ Cetacean Populations in Understanding Reproductive Physiology and Developing Assisted Reproductive Technology for Ex Situ and In Situ Species Management and Conservation Efforts

Autor: J. K. O’Brien, T. R. Robeck

Publikováno v: O’Brien, J. K.; & Robeck, T. R.(2010). The Value of Ex Situ Cetacean Populations in Understanding Reproductive Physiology and Developing Assisted Reproductive Technology for Ex Situ and In Situ Species Management and Conservation Efforts. International Journal of Comparative Psychology, 23(3). Retrieved from: http://www.escholarship.org/uc/item/1n15q19h

Wild cetacean populations have uncertain futures in the face of shifting climate conditions and the continued encroachment of their unique ecosystem by human activities. Core conservation efforts focus on habitat protection and understanding the natu

Effect of cryopreservation methods and precryopreservation storage on bottlenose dolphin (Tursiops truncatus) spermatozoa

Autor: T R, Robeck, J K, O'Brien

Publikováno v: Biology of reproduction. 70(5)

Research was conducted to develop an effective method for cryopreserving bottlenose dolphin (Tursiops truncatus) semen processed immediately after collection or after 24-h liquid storage. In each of two experiments, four ejaculates were collected fro

An evaluation of the accuracy of ageing horses by their dentition: a matter of experience?

Autor: P. J. N. Pinsent, J D Richardson, P J Cripps, J G Lane, J. K. O'brien, M. H. Hillyer

Publikováno v: Veterinary Record. 137:88-90

There is a widely held belief that a horse can be accurately aged by an examination of its teeth but this belief has recently been questioned. In this study photographs were taken of the dentition of 434 thoroughbreds of known age. Four experienced e

Second‐breakdown characteristics of metal‐oxide varistors

Autor: M. S. Cooper, J. J. Lee, J. K. O’Brien

Publikováno v: Journal of Applied Physics. 48:1252-1257

Several new results on the electrical breakdown properties of ZnO‐based ceramic varistors are presented. A second‐breakdown phenomenon associated with thermal runaway and characterized by a negative differential conductivity was observed in dc te
