Mosses are one of the best bioindicators in assessment atmospheric aerosol pollution by heavy metals. Studies using mosses allow both short- and long-term air quality monitoring. The increasing contamination environment (including air) is causing a search for new, cheap effective methods monitoring its condition. Once such method use active biomonitoring. aim study was to assess with selected m...

fusarium wilt caused by fusarium oxysporum f.sp. lycopersici is one of the major obstacles to the production of tomato which causes huge losses in tomato products worldwide. in order to increase the tolerance to this disease, a triple structure containing pr1, chitinase and glucanase genes controlled by 35s promoter was transferred to tomato. eight days after planting on pre-culture medium, exp...

The response to methimazole [1-methyl-2-mercapto-imidazole (MMI)] therapy, 10 mg twice daily in 15 patients and propylthiouracil (P TU) therapy, 100mg twice daily in 10 patients with diffuse toxic goiter was evaluated in an area of iodine deficiency (Tehran). The mean free T4 index (FT4I) decreased from 22.7± 6.8 (± SD) to 10.8± 2.8 In MMI-treated, and from 25.1± 6.8 to 13.2± 2.1 in PTU-tr...

Papaya is a tropical fruit with great appreciation by the population, for production of seedlings, substrates appear as importance development, providing seedling in pattern desired producers. The objective was to evaluate effect organic on emergence and development papaya seedlings cv Formosa “mel”. experiment carried out randomized block design, five treatments four replications. Fifty seeds ...

In this study, we test whether the δ(13)C and δ(15)N in a peat profile are, respectively, linked to the recent dilution of atmospheric δ(13)CO(2) caused by increased fossil fuel combustion and changes in atmospheric δ(15)N deposition. We analysed bulk peat and Sphagnum fuscum branch C and N concentrations and bulk peat, S. fuscum branch and Andromeda polifolia leaf δ(13)C and δ(15)N from a 30-c...

In early 1999, there was an increased incidence of tuberculous lesions in the lymph nodes of slaughtered pigs in the Czech Republic. In part 1 of this study, tuberculous lesions were detected in 140 (62%) tissue samples collected from pigs coming from 15 farms in 15 districts at routine veterinary meat inspections in abattoirs. Mycobacteria were isolated from 37 (16%) tissue samples: 34 Mycobac...

Recent climate change on the Antarctic Peninsula is well documented [1-5], with warming, alongside increases in precipitation, wind strength, and melt season length [1, 6, 7], driving environmental change [8, 9]. However, meteorological records mostly began in the 1950s, and paleoenvironmental datasets that provide a longer-term context to recent climate change are limited in number and often f...

This study describes the in vitro propagation and ex acclimatization of Philodendron erubescens pink princess, one most popular ornamental variegated foliage plants. For shoot proliferation, protocorm-like bodies princess were cultured on solid Murashige Skoog (MS) media supplemented with 6-benzylaminopurine (BAP) 1-naphthaleneacetic acid (NAA) at different concentrations. The results revealed ...
