An unusual feature of the saline stratified lakes that were formed due to ongoing postglacial uplift on the White Sea coast is the presence of several differently colored thin layers in the zone with sharp gradients. Colored layers in five lakes at various stages of separation from the sea were investigated using optical microscopy, spectrophotometry, spectrofluorimetry, and photobiology. The upper greenish colored layer located in the aerobic strata of all lakes near the compensation depth of 1% light penetration contains green algae. In the chemocline, another layer, brightly green, red or pink, is dominated by mixotrophic flagellates. despite the very low light intensities and the presence of H 2 S, active photosynthesis by these algae appears to be occurring, as indicated by high values of the maximum quantum yield of primary photochemistry, electron transport activity, photosynthetic activity of photosystem II, the fraction of active centers, and low values of heat dissipation. In the reduced zone of the chemocline, a dense green or brown suspension of anoxygenic phototrophs(green sulfur bacteria) is located.

目的:评估接受局部眼内压(IOP)降低治疗患者的药物依从性,并确定接受青光眼专家治疗的患者与接受普通眼科医生随访患者之间的药物依从性是否存在差异及导致依从性差的多个障碍。方法:横断面调查研究。纳入2020-10/2021-02共54名患者行局部降眼压药物,且受试者完成了一份定制调查问卷,评估药物依从性及其障碍。结果:约60%受试者未完全依从局部治疗。Pearson检验表明,依从性与是否接受青光眼专家的随访之间无显著关联(χ^(2)=1.2468,P=0.5361)。其次,43%的受试者排斥滴眼液,Logistic回归分析显示,受试者表现出低依从性(β_(1)=3.168,P=0.0367)。结论:问卷可有效评估对局部降IOP治疗的药物依从性及其障碍。本研究药物依从率非常低,因此必须实施策略应对影响依从性最常见的障碍。
