background:   objective: the aim of this study was to investigate the effects of aqueous and hydro-alcoholic extracts of lettuce seed on testosterone level and spermatogenesis.   materials and methods: in this experimental study 24 adult male nmri mice weighing 20-25gr were purchased. animals were randomly divided into 4 groups: controls, hydro-alcoholic (200 mg/kg) and aqueous extracts (50, 10...

Additional data on the synlophe and morphological measurements are provided for the heligmonellids Stilestrongylus aculeata (Travassos, 1918) and Stilestrongylus eta (Travassos, 1937), collected from Akodon montensis Thomas, 1913, of the Atlantic Forest, Rio de Janeiro, Brazil. The synlophe of S. aculeata is characterized by 19 cuticular middle body ridges in males and 24 cuticular middle body ...

The accumulation of Ag by the marine herbivorous gastropod, Littorina littorea, has been studied in a series of exposures in which the metal was added in aqueous form and as nanoparticles, both in the presence and absence of contaminated algal food (Ulva lactuca). Significant accumulation occurred in the gill, kidney, stomach and visceral mass when the snail was exposed to aqueous Ag in the abs...

The nutritional value of six tropical seaweeds (Sargassum wightii, Ulva lactuca, Kappaphycus alvarezii, Hypnea musciformis, Acanthophora spicifera and Gracilaria corticata) as complementary source of dietary proteins for human and animal nutrition based on amino acid profile was evaluated. All these species showed similar non-essential amino acid patterns in which aspartic and glutamic acids co...

Marine algae are considered a source of different bioactive constituents including protein, oil, fiber, vitamins, pigments and dietary minerals. To evaluate the fine chemical biochemical properties marine microalga Nannochloropsis oculata macroalga Ulva lactuca, present study was carried out. The cultivated N. oculate collected U. lactuca were washed, oven-dried, ground subjected to analysis mo...

Levels of radionuclides in seven species of marine brown algae and Ulva were determined to establish a baseline for the Northern Pacific Ocean/Bering Sea (Aleutian Islands). There were differences in levels among algal species and locations (Amchitka Island vs Kiska Island). No values were above the minimum detectable activity (MDA) level for (137)Cs, (129)I, (60)Co, (152)Eu, (90)Sr, and (99)Tc...
