the genetic polymorphism of insulin-like growth factor binding protein ( igfbp-3 ) and its association with the growth traits namely condition factor, body weight, and total length were investigated in common carp cyprinus carpio using pcr- single strand conformation polymorphism (sscp) technique. caudal fin clips from 120 c. carpio , aging 5 months, were used in this study and a 330 bp dna fra...

this study was aimed to investigate some feeding characteristics of kura barb (barbus lacerta) from bibi-sayydan river of semirom, isfahan. for this purpose, during august 2010 to july 2011, some 445 specimens of the kura barb fish were caught using a seine net and a cast net and transferred to the fisheries laboratory on ice for further examinations. the results showed that the condition facto...

The current paper determines heavy metals in sediments of six freshwater wetlands of greater Dhaka district from November 1999 to September 2000. The sampling took place in summer, rainy season, and winter, wherein for each season five soil samples were collected from the wetland at a depth of 0 – 15 cm. To assess the status of heavy metal pollution in the sediments, geo-accumulation factor (Ig...

The performance of two strains Nile tilapia (the Nyakabera and Lake Kivu) fed a commercial feed or either fishmeal-based fishmeal-free formulated using local ingredients was evaluated for 99 days in Bukavu, eastern highlands the DR Congo (Experiment 1). Strain × interaction significant (p < 0.05) final body weight (FBW) condition factor (CF). Growth both best with feed. Fish-meal free result...

Cystic fibrosis (CF) is a lethal, hereditary disorder characterized by a neutrophil-dominated inflammation of the lung. We sought to determine whether neutrophils from individuals with CF release more neutrophil elastase (NE) than neutrophils from normal subjects. Our results showed that peripheral blood neutrophils (PBNs) from normal subjects and individuals with CF contained similar amounts o...

Condition indices are key predictors of health and fitness in wild fish populations. Variation body condition, therefore, can be used to identify stressful conditions that may impact endangered species, such as California’s endemic Delta Smelt (Hypomesus transpacificus McAllister, 1963). Here, we examined spatiotemporal variation the condition > 1600 collected over nine years (2011–2019), a per...

some 190 specimens of sefidrud loach, oxynoemacheilus bergianus , were collected from aras river (northwestern iran) and age, size, and some biological characteristics of the samples were investigated from march to july 2013. the maximum age was 3 + years. the specimens ranged in size from 42 to 64mm for males and 45 to 61mm for females in total length, weighing from 0.62 to 2.03g for males and...

Interleukin (IL)-17 is pivotal in orchestrating the activity of neutrophils. Neutrophilic inflammation is the dominant pathology in cystic fibrosis (CF) lung disease. We investigated IL-17 protein expression in the lower airway in CF, its cellular immunolocalisation and the effects of IL-17 on CF primary bronchial epithelial cells. Immunohistochemistry was performed on explanted CF lungs and co...

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 external features of ...
