in this study, a total of 146 specimen of fish species from garmrood river of amol, mazandaran province in the summer 2011 were caught by local fishermen which including ,10 sand goby (neogobius fluviatilis),4 round goby (neogobius melanostomus), 48 capoeta capoeta, 73 albernoides bipunctatus, 5 leuciscus cephalus, 7 cobitis taenia and 4 nemacheilus nemacheilus. the fishes were transported a li...

in this study, the effect of garlic extract on the growth performances ( body weight increase (bwi), specific growth rate (sgr), condition factor (cf), final length (fl) and weight (fw)), feed indices (feed conversion rate (fcr), protein efficiency ratio (per), protein production ratio (ppr)) and body composition (protein, fat, moisture and ash) of mugil cephalus larvae were studied in four tre...

Many chemical, physiological, and trophic factors are known to affect bioaccumulation of polychlorinated biphenyls (PCBs) in biota. Understanding the primary factors affecting fish contamination is critical for predicting and assessing risks to upper-trophic level consumers, including humans. Here we identify PCB contamination pathways that could explain within- and between-species variability ...

The infection of the estuarine teleost fishes Mugil gaimardianus Desmarest, 1831 (Mugilidae), Arius phrygiatus Valenciennes, 1839 (Ariidae), Conodon nobilis Linnaeus, 1759 (Haemulidae), Cetengraulis edentulus Cuvier, 1829 (Engraulidae), and Anableps anableps Linnaeus, 1758 (Anablepidae) by praniza larvae of Gnathiidae (Crustacea, Isopoda) was studied in specimens fished off the Atlantic Ocean i...

Haemoglobin, the 'honorary enzyme' [Brunori (1999), Trends Biochem. Sci. 24, 158-161], constitutes a prime prototype for allosteric models. Here, the crystallization and preliminary X-ray analysis of haemoglobin I from the South American fish Brycon cephalus are reported. X-ray diffraction data have been collected to 2.5 A resolution using synchrotron radiation (LNLS). Crystals were determined ...

The aim of the present study was to determine the presence of p,p’-DDT and its metabolites (p,p’DDE and p,p’-DDD) and ã-HCH and PCBs in the muscle of gray mullet, Mugil cephalus collected from Cuddalore coast of Bay of Bengal during the period from June 2009 to January 2010. Polychlorinated hydrocarbons are convenient indicators of environmental pollution. The analyses were carried out using th...

A 66 year-old woman with congenital macro cephaly and developmental delay presented with aphasia and right-sided weakness. Head CT revealed severe hydrocephalus of the lateral and third ventricles with a normal fourth ventricle due to a chronic congenital process (Fig. 1A). MRI confirmed subacute embolic infarcts of the left middle cerebral artery territory (Fig. 1B) and a heparin drip was init...
