Expression of cytochrome P4501A (CYP1A) has been used as a biomarker for possible exposure to contaminants such as PCBs and dioxins in teleost fish. Using a quantitative reverse transcription-polymerase chain reaction (Q-RT-PCR) and a non-lethal gill biopsy, we estimated levels of CYP1A mRNA expression in Atlantic salmon (Salmo salar). Groups of ten Atlantic salmon juveniles (48-76 g) received ...

Chest radiographs taken by a standard technique were obtained from 173 current employees (164 men, 9 women) of a vermiculite mine in Montana, from 80 of 110 past employees resident within 200 miles, and from 47 men from the same area without known exposure to dust. In 43 of the 80 and 24 of the 47 an earlier chest x ray film was retrieved from the hospital archives. All 367 films were assessed ...

Background. Infliximab (INF) has been shown to be beneficial in treating refractory uveitis, however, no data exist on optimal dosing and the efficacy of higher dosing. Objectives. To compare the efficacy of low-dose (LD) (<10 mg/kg), moderate-dose (MD) (≥10-15 mg/kg), and high-dose (HD) INF (≥15-20 mg/kg) in the treatment of uveitis. Methods. Retrospective chart review children with uveitis di...

This study describes criteria used by graduate nurse anesthesia educational programs (GNAEPs) in selecting students for admission. The investigators prepared and distributed a 15-item questionnaire to 71 GNAEPs as listed by the Council on Accreditation of Nurse Anesthesia Eduational Programs for December 1992. Thirty-eight of 71 (54%) of GNAEPs participated in this study. Upon examination of st...

AIM: This case report presents one such case which has been successfully treated using inversely placed periosteal pedicle graft. BACKGROUND: Various periodontal surgical procedures have evolved over time for obtaining complete root coverage of isolated single tooth miller’s class I and class II gingival recession defects. CASE DESCRIPTION: inversely placed Periosteal pedicle graft is a latest ...

The management of cane supply from growers’ fields to the mill involves many stakeholders and many tasks to be carried out along the chain, the successful combination of which impacts on the efficiency and profitability of the mill area. A simulation tool called MAGI has been developed to assist millers and growers in designing and assessing new ways of organising supply management. The issues ...

Introduction. Gingival recession is an apical shift of the gingival margin with exposure of the root surface. This migration of the marginal tissue leads to esthetic concerns, dentin hypersensitivity, root caries, and cervical wear. It is, paradoxically, a common finding in patients with a high standard of oral hygiene, as well as in periodontally untreated populations with poor oral hygiene. C...

OBJECTIVE To reanalyse data on the lung content of asbestos fibres among brake mechanics. METHODS I re-analysed data published by Butnor, Roggli and colleagues on the lung content of chrysotile and tremolite asbestos fibres among brake mechanics and controls. Statistics of the distributions were estimated by maximum likelihood to accommodate observations below the detection limit. Mean concen...
