A new species of araphid diatom is described from a temporary stream in southern Portugal, Fragilaria odeloucaensis sp. nov., which belongs to the group with widely linear lanceolate valve outline, spaced striae, lacking spines, and well-developed apical pore fields. The taxon can be distinguished based on five unique features within this group, valves capitate apices, zig-zagged axial area, ce...

A novel flap double twist technique was applied to reduce the incidence of post-laser-assisted in situ keratomileusis (LASIK) flap striae. The flap is floated and stroked in the same way as is done for management of first postoperative day striae, where the method is to float and irrigate the flap into position, followed by applying gentle pressure on the flap with a wet Merocel microsponge and...
