Free radical-induced oxidative damage is implicated in the pathogenesis of neurodegenerative disorders, and antioxidants are presumably of therapeutic value in such diseases. Our previous data indicated that free radicals are strongly associated with brain aging and also play an important role in cytotoxicity of amyloidogenic proteins including -synuclein and amyloid , which accumulate in bra...

Condition factor is a measure of energetics, nutritional status and viability host. Changes in the host condition have effect on rate infection. 100 fishes Sarotherodon melanotheron 90 Parachanna obscura from Lekki lagoon were procured dissected for intestinal helminth parasites. factors all individuals determined. Median (K < 1.32 K > 1.32) 4.09 4.09) used grouping individuals. Male fema...

Aquatic systems are affected by a variety of anthropogenic activities that decrease water quality through the introduction of organic and inorganic pollutants. To investigate the relationship between fish parasite communities and water quality, metazoan parasites were examined in 140 specimens of the Mozambique tilapia (Oreochromis mossambicus) sampled in three lakes in the Limpopo Province...

The work describes the flora of higher sporeless vascular plants (superdivision Bryobionta, divisions Marhantiophyta, Bryophyta) and spore (divisions Lycopodiophyta, Equisetophyta, Psilotophyta, Polypodiophyta) Poltava region, analyzed peculiarities its systematic taxonomic composition. As a result research, it was established that bryobiont includes 167 species, 87 genus, 43 families. Lycopodi...

Diplostomoid digenean metacercariae have caused widescale mortalities of channel catfish, Ictalurus punctatus (Rafinesque), at aquaculture farms in Louisiana, Mississippi and Arkansas, USA. Originally, based on a tentative diagnosis, the industry considered the primary harmful agent to be an introduced species from Europe, Bolbophorus confusus (Krause, 1914), frequently reported from the Americ...

The sanguinicolids Paracardicoloides yamagutii Martin, 1974 and Plethorchis acanthus Martin, 1975 were obtained from their definitive hosts, Anguilla reinhardtii Steindachner and Mugil cephalus Linnaeus (respectively) in the tributaries of the Brisbane River, Queensland, Australia. Two putative sanguinicolid cercariae were collected from a hydrobiid gastropod, Posticobia brazieri Smith, in the ...
