This study aimed to develop sex reversal procedures targeting the embryonic period as tools to study the early steps of sex differentiation in Nile tilapia with XX, XY, and YY sexual genotypes. XX eggs were exposed to masculinizing treatments with androgens (17α-methyltestosterone, 11-ketotestosterone) or aromatase inhibitor (Fadrozole), whereas XY and YY eggs were subjected to feminizing treat...
abstract english language learning in iran has become significant in recent years, and english has been included in the curriculum of iranian schools and universities, and considerable attention has been paid to this language in our society. nevertheless, teaching and learning english in iranian schools has not been able to satisfy the specified goals, so different efl institutes have been est...
We intended to verify the safety of the freshwater values established for cadmium by the European Community and the Italian Ministry of Health in drinking water (5 μg/L) and sewage waters (20 μg/L). Therefore, we chronically exposed the newt Triturus carnifex to 5 μg/L and 20 μg/L doses of cadmium, respectively, during 3 and 9 months and verified the effects on the adrenal gland. We evaluated t...

The toxicity of a mentholated version of the Tobacco Heating System (THS2.2M), a candidate modified risk tobacco product (MRTP), was characterized in a 90-day OECD inhalation study. Differential gene and protein expression analysis of nasal epithelium and lung tissue was also performed to record exposure effects at the molecular level. Rats were exposed to filtered air (sham), to THS2.2M (at 15...
cyanobacteria blooms are common in baltic sea and their intensity have been increased due toanthropogenic eutrophication. in this study we investigated the cyanotoxin levels in the water samplescollected from four different locations in the baltic sea at three different seasons including summer 2011.protein phosphatase 2a (pp2a) inhibition assays, enzyme-linked immunosorbent assays (elisa) and ...
Efficacy and safety of umeclidinium administered in a dry power inhaler were evaluated in moderate-to-very-severe chronic obstructive pulmonary disease patients. This was a randomised, placebo-controlled study assessing once-daily umeclidinium 62.5 and 125 μg over 12 weeks. The primary end-point was change from baseline in trough forced expiratory volume in 1 s (FEV1) on day 85. Secondary end-p...
This study was undertaken to develop molecular tools to assess water quality using diatoms as the biological model. Molecular approaches were designed following the development of a rapid and easy RNA extraction method suited to diatoms and the sequencing of genes involved in mitochondrial and photosystem metabolism. Secondly the impact of cadmium was evaluated at the genetic level by q-PCR on ...
