From our evaluation, both the selected consolidation methods
appeared unsuitable to be used in paper restoration because of the damage that they could cause on the paper materials because of their limited durability over time. (C) 2009 Wiley Periodicals, Inc. J Appl Polym Sci 112: 3529-3536, 2009″
“Objective-To determine whether the presence of Chlamydophila psittaci antigen, plasma cholesterol concentration, diet, sex, species, and age are risk factors for the development of atherosclerosis in pet psittacine birds.
Design-Retrospective case-control study.
Animals-31 psittacine birds with atherosclerosis (study birds) and 31 psittacine birds without atherosclerosis (control birds).
Procedures-Necropsy reports were reviewed, birds with a histopathologic diagnosis of atherosclerosis selleck chemical were identified, and available medical records were reviewed. Signalment, history, clinicopathologic findings, and other relevant data were recorded and evaluated. Control birds did not have atherosclerosis and were chosen by both convenience sampling and population demographics. Histologic sections of great vessels from all birds (study and control birds) were reviewed and then submitted for immunohistochemical staining for the presence of C psittaci antigen.
Results-Result
of immunohistochemical staining for C psittaci antigen in blood vessels was significantly associated Ulixertinib clinical trial with atherosclerosis. After adjusting for age, species origin, and type of illness, the odds of atherosclerosis was 7 times as high for birds with positive immunohistochemical staining for C psittaci antigen, compared with that of birds with negative immunohistochemical
staining. Study birds and control birds differed significantly only with respect to plasma cholesterol concentrations. The median plasma cholesterol concentration of study birds (421 mg/dL) was significantly higher than that of control birds (223 mg/dL).
Conclusions and Clinical check details Relevance-Infection with C psittaci and a high plasma cholesterol concentration may be risk factors for developing atherosclerosis in pet psittacine birds. (J Am Vet Med Assoc 2012;240:1474-1480)”
“Objective: Resistance to anti-tuberculosis (anti-TB) drugs is becoming a major and alarming threat in most regions worldwide.
Methods: This was a descriptive cross-sectional study at a tertiary hospital in Iran, using patient medical records for 2000-2003. The findings were analyzed following the same framework as that used for previous reports from this center.
Results: Among 1556 TB patients, drug susceptibility testing (DST) was performed for 548 culture-positive cases. Anti-TB drug resistance to both isoniazid and rifampin was identified in 10 (2.8%) of the new TB cases (multidrug-resistant TB; MDR-TB). Any resistance was detected in 228 (41.6%), showing an increasing trend in both new and retreatment cases.
