The knowledge about the effects of pharmaceuticals on aquatic organisms has been increasing in last decade. However, due to variety compounds presents medium, exposure scenarios and exposed organisms, there are still many gaps how mixtures such bioactive affect non target organisms. crayfish Procambarus clarkii was used analyze toxicity ciprofloxacin, flumequine ibuprofen at low high concentrat...

The main purpose of this study is to the effect live oysters on various quality indicators after alkaline electrolytic seawater depuration. depuration treatments were carried out for 12 h at temperatures 5 °C, 10 15 and 20 pH = 9, 10, 11, respectively. total aerobic plate count (TAPC) oyster meat was reduced from about 5.2 ± 0.4 log CFU/g below detection limits when depurated in 11 9 °C °C. At ...

In recirculating aquaculture systems (RAS), off-flavors can accumulate in fish muscle tissue. They are problematic for consumer acceptance and the reputation of farmed products. Although not toxic at low concentrations, they often give earthy, muddy, or other unwanted flavors. Traditionally, study focused on muddy earthy caused by geosmin (GSM) 2-methylisoborneol (MIB), but flavors compounds ha...

background and aims. previous researches, conducted mostly on extracted teeth, have shown that efficacy of calculus removal decreases with increasing pocket depth, but there is still a lack of clinical studies concerning the correlation be-tween residual calculus and varying pocket depths. the objective of the present clinical study was to assess the efficiency of mechanical tooth depuration by...

The assumption of the individual effective dose is the basis for the probit method used for analyzing dose or concentration-response data. According to this assumption, each individual has a uniquely innate tolerance expressed as the individual effective dose (IED) or the smallest dose that is sufficient to kill the individual. An alternative to IED, stochasticity suggests that individuals do n...

Dietary and nondietary accumulation of waterborne zinc (Zn) by shell of abalone Haliotis diversicolor supertexta was studied to determine if abalone shell can accumulate and eliminate Zn biokinetically. Shell of H. diversicolor supertexta rapidly accumulated Zn at microgram per gram concentrations during a 7-d uptake period for dietary and nondietary exposure to 1 microgml(-1) Zn seawater. Depu...

The marine environment is subjected to contamination by a complex mixture of metals from various anthropogenic sources. Measuring the biological responses of organisms to a complex mixture of metals allows for examination of metal-specific responses in an environmentally realistic exposure scenario. To address this issue, the sea anemone, Aiptasia pallida was exposed to a control and a metal mi...

Introduction Vibrio parahaemolyticus (Vp) and Vibrio vulnificus (Vv) are human pathogens commonly associated with bivalve shellfish. These Vibrios cause infections to humans when patients consume raw or undercooked shellfish or when it’s in free-living form in estuarine environments. There are three clinical manifestations of disease caused by Vp and Vv; most common for Vp is gastroenteritis an...

A lack of knowledge persists concerning the combination of kinetics on protein and mRNA levels of the most commonly used biomarker for estrogenic influences-vitellogenin (VTG). Consequently, male fathead minnows were exposed to 17alpha-ethinylestradiol (EE(2)) for 35 days, followed by an equally long depuration period in a flow-through system. VTG mRNA levels reached a plateau after 3 days of e...

Uptake and depuration of paralytic shellfish toxins in the green-lipped mussel, Perna viridis, were investigated by exposing the mussels to dinoflagellates (Alexandrium tamarense, ACTI01) under laboratory conditions for 8 d, then depurating them in clean seawater for 14 d. First-order linear differential equations were set up for five tissue compartments: Viscera, gill, hepatopancreas, adductor...
