1. EFFECTS OF THE DIETARY SUPPLEMENTATION WITH A MICROALGA EXTRACT ON BROILER PERFORMANCE AND FATTY-ACID MEAT PROFILE
ABSTRACT The present study was carried out in the poultry sector of UNOESC Xanxerê to evaluate the effect of various inclusion levels of seaweed (Schizotrichium ssp.) in the diet of broiler chickens in terms of performance, carcass yield, organ profiles and fatty acids levels in meat. We studied 480 one-day-old Cobb chicks, distributed in a completely rando

2. Replacing sodium bicarbonate with half amount of calcareous marine algae in the diet of beef cattle
ABSTRACT This study evaluated the effects of feeding calcareous marine algae or sodium bicarbonate as rumen buffer on the performance, behaviour, in vitro diet digestibility, and meat quality of beef cattle. A total of 180 Charolaise bullocks (536±38 kg; 14±1 months of age) were divided into two homogeneous groups and fed a diet with a mineral mix containi

4. Antioxidant activity of ethyl acetate and methanolic extracts of two marine algae, Nannochloropsis oculata and Gracilaria gracilis - an in vitro assay
ABSTRACT The aim of this study was to evaluate the antioxidant activity of ethyl acetate and methanolic extracts of two marine algae, Nannochloropsis oculata and Gracilaria gracilis. The extracts were assayed for total phenol and flavonoid content, DPPH free radical scavenging capacity, nitric oxide activity, iron chelation activity, and reducing power activ

5. An overview of odoriferous marine seaweeds of the Dictyopteris genus: insights into their chemical diversity, biological potential and ecological roles
ABSTRACT Since the middle of the twentieth century the marine algae have attracted attention as a source of new drugs. Dictyopteris is an important group of marine seaweeds and is widely distributed in tropical, subtropical and temperate regions. This genus is known by its characteristic “ocean smell”. Some species show a distinct phytochemistry, with sp

6. Fatty acid composition from the marine red algae Pterocladiella capillacea (S. G. Gmelin) Santelices & Hommersand 1997 and Osmundaria obtusiloba (C. Agardh) R. E. Norris 1991 and its antioxidant activity
ABSTRACT This study evaluated the chemical composition and antioxidant activity of fatty acids from the marine red algae Pterocladiella capillacea (S. G. Gmelin) Santelices & Hommersand 1997 and Osmundaria obtusiloba (C. Agardh) R. E. Norris 1991. The gas chromatography mass spectrometry (GC-MS) identified nine fatty acids in the two species. The major fatty

7. Paleoenvironmental evolution of the coastal plain of Southern Brazil: palynological data from a Holocene core in Santa Catarina State
ABSTRACT This paper presents a paleoenvironmental reconstruction from palynological analyses of a sedimentary core of Holocene age, drilled at municipality of Garopaba (Santa Catarina), Southern Brazil. A total of 46 samples was collected for palynological analyses in the 450 cm-long core PCSC-3, as also three samples for radiocarbon dating and granulometric

9. Intraspecific variation of meroditerpenoids in the brown alga Stypopodium zonale guiding the isolation of new compounds
Abstract Intraspecific variation on meroditerpenoids production by the brown marine alga Stypopodium zonale at four different populations along the Brazilian coast was analyzed using Principal Component Analysis over high-performance liquid chromatography profiles from algae extracts. The ordination of the samples by the similarities of their chromatographic

10. Anti-inflammatory effects of methanolic extract of green algae Caulerpa mexicana in a murine model of ulcerative colitis
Abstract Inflammatory bowel diseases, which include Crohn's disease and ulcerative colitis, are characterized by chronic and relapsed gut inflammation. Caulerpa mexicana is a type of green marine algae that can be found in tropical areas, such as the Brazilian Coastland. These macrophytes exhibit in vitro and in vivo anti-inflammatory properties such as the

11. Antischistosomal activity from Brazilian marine algae
Abstract Schistosomiasis may be caused by six different species of the genus Schistosoma. Current treatment is based only on two drugs: oxamniquine, which is only effective against the Schistosoma mansoni species, and praziquantel, which is ineffective against young parasites. Therefore, research on new drugs and their targets for the treatment of this disea

12. Antinociceptive activity of Sargassum polyceratium and the isolation of its chemical components
Abstract Marine algae have been the focus of important studies over the past fifty years, with a considerable number of components important to chemists and taxonomists having been isolated and characterized. The scientific data available on Sargassum polyceratium are extremely limited. The objective of the present study was to evaluate the antinociceptive a
