this paper presents  the  levels  of total  mercury  (t-hg)  in  dorsal  muscle,  liver  and  spleen of pike  (esox lucius) from  anzali  lagoon  in iran.  sampling were  carried  out from  july  2004 to july 2005. in addition 78 samples were collected. t-hg concentration  were  calculated  in relation to biometric factors. t-hg was measured by the leco ama 254 advanced mercury analyzer (usa) a...

Basement membranes are specialized extracellular matrices that play fundamental roles in tissue development and function. These thin sheet-like structures are produced through complex interactions between the major components laminins, collagen IV, the heparan sulfate proteoglycan perlecan and nidogen (Mayer and Timpl, 1993). Laminins are heterotrimeric crossshaped multidomain molecules compose...

Background—Results from observational studies on fish consumption and coronary heart disease (CHD) mortality are inconsistent. Methods and Results—A meta-analysis of cohort studies was conducted to examine the association between fish intake and CHD mortality. Studies were included if they provided a relative risk (RR) and corresponding 95% CI for CHD mortality in relation to fish consumption a...

PURPOSE To quantify and localize plasmid transfection of filtration surgery tissues using two delivery techniques. METHODS Full-thickness filtering procedures were performed on eyes of New Zealand albino rabbits. In 10 eyes, naked plasmid DNA in saline was either injected beneath Tenon's capsule at the filtration site or absorbed into a collagen shield that was then placed external to the scl...

Manganese stabilizing protein (MSP) is an intrinsically disordered extrinsic subunit of photosystem II that regulates the stability and kinetic performance of the tetranuclear manganese cluster that oxidizes water to oxygen. An earlier study showed that deletion of the (1)E-(3)G domain of MSP caused no loss of activity reconstitution, whereas deletion of the (4)K-(10)E domain reduced binding of...
