Cystic fibrosis (CF) is a recessive genetic disease characterised by impaired muco-ciliary clearance. Although the disease affects multiple organs, 85% of mortality results from lung pathology relating to persistent recurrent infections, an exaggerated inflammatory response and progressive airways obstruction which ultimately leads to respiratory failure. Haemoptysis is a common symptom of CF w...

selenium, a trace mineral complement is used as cofactor of antioxidant enzymes that protects fishes against environmental stress agents and enhances performance in fishes. in this study the different levels of organic and inorganic source of  selenium were included in juvenile rainbow trout diet to evaluate feed conversion ratio (fcr), specific growth rate (sgr), weight gain percent (wg), cond...

the present study investigated effects of starvation on growth, body chemical composition and non-specific immune parameters in yellow fin seabream.  in this study, 120 fish with a mean length of 8.05± 0.98 cm and weight of 7.46± 1.07 g (was referred as size a) and 120 fish with a mean length of 11.05 ± 0.86 cm and weight of 18.01± 3.07 g (was referred size b) were used with each size was compr...

Objective: This study was conducted to evaluate the effects of different proportions of marshmallow extract (Althaea officinalis L.) on growth performance and carcass composition of common carp (Cyprinus carpio). Methods: Common carp with an average weight of 37.65 ± 4.40 g were fed for two months with a diet supplemented with marshmallow (A. officinalis) ext...

The Length-Weight Relationship (LWR) and condition factors (CF) of 180 the oriental river prawn Macrobrachium nipponense collected from southern coasts of the Caspian Sea from May through September 2012 were studied. Shrimp samples were taken and immediately transferred to the laboratory of fish biology at University of Guilan for further analyses. Length, weight and other ext...

artemia plays a major role in aquaculture as one of the most important live foods used in larval rearing. the aim of this study was to determine the optimum level of feeding in artemia urmiana with baker's yeast (saccharomyces cerevisiae). triplicate groups were fed with different levels of s. cerevisiae yeast 0.625 (control), 1.25 (t1), 2.50 (t2), 5.0 (t3) (mg yeast per 1000 nauplii) for ...

Bioaccumulation of Cu, Zn, Hg in muscles and liver tissues of stellate sturgeon (Acipenser stellatus) from the southern Caspian Sea was measured. Effects of condition factor (CF), age and hepatosomatic index (HSI) on metal accumulation were also determined. Some 40 stellate sturgeons were collected using gill nets in winter and spring 2007-2008 from the southern shores of the Caspian Sea. Total...

The population structure of Aphanius mento in the Seyhan Reservoir was studied on the basis of 834 fish specimens (516 males and 318 females) caught on a monthly basisbetween September 2013 and August 2014. Fish were collected using dip nets of tulle with a 1mm mesh size. The maximum age of fish was found to be 4 years for both sexes combined, the 1 year old age group comprised 62.20% of male s...

prediction of climatic variables on a local scale by general circulation models of the atmosphere is impossible because the models have large-scale network of resolution. therefore, downscaling methods are used to solve this problem. since the climate change phenomenon can affect different systems such as, water resources, agriculture, environment, industry and economy as well, selection of the...

Cystic fibrosis (CF) is characterized by chronic lung infection and inflammation, with periods of acute exacerbation causing severe and irreversible lung tissue damage. We used protein and glycosylation analysis of high-molecular mass proteins in saline-induced sputum from CF adults with and without an acute exacerbation, CF children with stable disease and preserved lung function, and healthy ...
