All the Tzanck smears and 1 biopsy revealed multinucleated giant cells, consistent with herpes simplex virus (HSV) or varicella zoster virus (VZV) infection. Immunohistochemistry using specific anti-VZV antibodies (IE63 and gE) was positive on all the smears and the biopsy, whereas HSV-I and HSV-II immunolabeling was negative. VZV specific IgM+, IgG- EIA-based Quizartinib mouse serology, and positive VZV-specific IgM complement fixation test suggested primary VZV infection.
None had received varicella vaccine. None of the patients presented a history of varicella nor experienced breakthrough varicella. It was decided not to administer antiviral treatment, as the varicella lesions remained localized without any further skin extension and systemic signs. About 2 months later, EIA-serology revealed positive VZV-IgG and negative IgM levels in 5/5 patients.
Conclusion: Some patients have varicella infection that remains hidden in a pre-existent infectious and/or inflammatory dermatitis without ever presenting full-blown chickenpox. The sudden occurrence of vesicular and/or ulcerated lesions on a pre-existent dermatitis should prompt searching for
a viral infection.”
“The objective of this study was to determine if developing barley (Hordeum vulgare L.) seeds had differences this website in beta-amylase 1 (Bmy1) mRNA accumulation, beta-amylase (EC 184.108.40.206) activity,
beta-amylase protein accumulation, and total protein levels during late seed development from genotypes with different Bmy1 intron III alleles. Two North American malting barley cultivars (Hordeum vulgare ssp. vulgare) were chosen to represent the Bmy1.a and Bmy1.b alleles and, due to limited Bmy1 intron find more III allele variation in North American cultivars, two wild barleys (Hordeum vulgare ssp. spontaneum) were chosen to represent the Bmy1.c and Bmy1.d alleles. Wild barleys Ashqelon (Bmy1.c) and PI 296897 (Bmy1.d) had 2.5- to 3-fold higher Bmy1 mRNA levels than cultivars Legacy (Bmy1.a) and Harrington (Bmy1.b). Levels of Bmy1 mRNA were not significantly different between cultivated or between wild genotypes. In all four genotypes Bmy1 mRNA levels increased from 17 to 19 days after anthesis (DAA) and remained constant from 19 to 21 DAA. Ashqelon and PI 296897 had more beta-amylase activity on a fresh weight basis than Legacy and Harrington at all developmental stages. beta-Amylase protein levels increased from 17 DAA to maturity in all genotypes. Total protein in grains from wild genotypes was significantly higher than cultivated genotypes at all developmental stages. Higher levels of total protein in Ashqelon and PI 296897 could explain their higher levels of beta-amylase activity, when expressed on a fresh weight basis.
