Crystal structure of the tegument protein UL82 (pp71) from human cytomegalovirus.

Human cytomegalovirus (HCMV) is an opportunistic pathogen that infects a majority of the world population. It may cause severe disease in immunocompromised people and lead to pregnancy loss or grave disabilities of the fetus upon congenital infection. For effective replication and lifelong persistence in its host, HCMV relies on diverse functions of its tegument protein UL82, also known as pp71.

Impact of molecular screening for point mutations and rearrangements in routine air-dried fine-needle aspiration samples of thyroid nodules.

Background: The diagnostic limitations of thyroid fine-needle aspiration (FNA), such as the indeterminate category, can be partially overcome by molecular analyses. However, until now, rearrangements have only been detected in fresh FNA material and the number of follicular thyroid carcinomas (FTCs) was rather low in previous studies. We aimed at investigating the impact of point mutations and rearrangement detection in a set of routine air-dried FNA smears with a higher percentage of FTCs.

Impact of different methodologies on the detection of point mutations in routine air-dried fine needle aspiration (FNA) smears.

Currently the best method to select suspicious thyroid nodules for surgery is fine needle aspiration (FNA) cytology. However, FNA cytology has some inherent limitations, which can partly be overcome by molecular analysis. Therefore, molecular testing for somatic mutations has emerged as the most promising approach for molecular FNA diagnostics.

Detection of PAX8/PPARG and RET/PTC rearrangements is feasible in routine air-dried fine needle aspiration smears.

Background: The diagnostic limitations of fine needle aspiration (FNA), like the indeterminate category, can be partially overcome by molecular analysis. As PAX8/PPARG and RET/PTC rearrangements have been detected in follicular thyroid carcinomas (FTCs) and papillary thyroid carcinomas (PTCs), their detection in FNA smears could improve the FNA diagnosis. To date, these rearrangements have never been analyzed in routine air-dried FNA smears, but only in frozen tissue, formalin-fixed paraffin-embedded (FFPE) tissue, and in fresh FNA material.

[Influencing the prescriptions of general practitioners via guidelines and feedback--secondary publication].

We investigated the effects of a multi-dimensional intervention on practice prescription patterns in five drug groups. The number of prescribed defined daily doses (DDDs) increased after the intervention, while potential savings/DDD decreased. The county's average cost/DDD fell to a level below the national average.

Changing GPs' prescription patterns through guidelines and feedback. Intervention study.

Purpose: To investigate whether and how a multi-dimensional intervention including clinical guidelines on the choice of medical treatment in the primary and the secondary health care sector, and individual feedback to general practices about their own and other practices' prescription patterns in five Anatomical Therapeutic Chemical classification system (ATC)-groups was followed by changes in the practices' prescription pattern.

Methods: Prospective historical registry study and a questionnaire study of GPs' self-reported use of guidelines and feedback.

Results: In every ATC-group the number of prescribed defined daily doses (DDDs) kept growing after the intervention, while potential savings by DDD decreased.

Osteochondrosis in feedlot cattle.

Beginning in summer 1977 and continuing through four consecutive seasons, we examined lame limb joints from 106 partially fattened cattle and 28,235 pairs of occipital condyles from fully fattened cattle for osteochondrosis. Of the 106 lame cattle, nine (8.5%) had characteristic lesions, usually in their stifle joints, and of the 28,235 atlanto-occipital joints, 1063 (3.

Laryngeal diphtheria and papillomatosis in feedlot cattle.

In a random sample of 30,444 larynges from slaughtered beef cattle, 441 (1.4%) had chronic diphtheria and 1,345 (4.4%) had papillomatosis.

Laryngeal contact ulcers in feedlot cattle.

Of 30,444 larynges from fattened cattle at three companies, 3,985 (13.1%) had contact ulcers or ulcer scars in the mucous membranes over the vocal processes and medial angles of the arytenoid cartilages. The incidence was higher in cattle fed during fall than in cattle fed during other seasons.

Limb arthropathies and periarticular injuries in feedlot cattle.

Beginning summer 1977 and continuing through 4 consecutive seasons, we examined samples of at least 25, and a total of 106, lame limbs or joints from slaughtered beef cattle. Of this number about 64 (60%) were articular and 42 (40%) periarticular lesions. Fifty-three were caused by trauma and 9 by osteochondrosis.
