Fungal infection of the filamentous cyanobacterium Anabaena smithii was observed in Lake Shumarinai in 2004–2006. Two fungal species were found to parasitize the specialized cells of A. smithii. These fungi might not correspond to the chytrid species that the previous studies reported as the parasites for Anabaena species. One fungus showed selective attachment to the akinete (akinete type). The filaments...
The diatom biomass of Lake Barato, as measured from July to September, decreased simultaneously with an increase in filament density of Phormidium tenue after 1997. There was a high negative correlation between the diatom biomass and the densities of P. tenue (r2 = 0.928). Although total nitrogen (TN) and total phosphorus (TP) concentrations decreased from 1996, TN:TP ratio increased from 1997 because...
Abstract A successful laparoscopic hernia repair requires complete covering of the hernia defect, adequate tension of the prosthesis, and secure stapling with a stapler. We describe herein our technique of performing laparoscopic hernia repair using a needlescopic instrument which results in minimal damage to the abdominal wall and has significant cosmetic benefits.
