Mechanisms of Spirodela polyrhiza tolerance to FGD wastewater-induced heavy-metal stress: Lipidomics, transcriptomics, and functional validation.

Unlike terrestrial angiosperm plants, the freshwater aquatic angiosperm duckweed (Spirodela polyrhiza) grows directly in water and has distinct responses to heavy-metal stress. Plantlets accumulate metabolites, including lipids and carbohydrates, under heavy-metal stress, but how they balance metabolite levels is unclear, and the gene networks that mediate heavy-metal stress responses remain unknown. Here, we show that heavy-metal stress induced by flue gas desulfurization (FGD) wastewater reduces chlorophyll contents, inhibits growth, reduces membrane lipid biosynthesis, and stimulates membrane lipid degradation in S.

Guillain-Barré syndrome complicating early pregnancy: a case report from Nepal.

Unlabelled: Guillain-Barré syndrome (GBS) is an immunological demyelinating disorder characterized by progressive, ascending flaccid weakness, usually resulting after infection or some immune stimulation. Its occurrence during pregnancy is rare and due to attribution of its symptoms to pregnancy, diagnosis might be delayed.

Case Presentation: A 39-year-old G4P3L2A0 woman at 13 weeks 6 days period of gestation presented with acute, symmetrical, ascending type of flaccid quadriparesis leading to slurring of speech, swallowing difficulty, and eventually respiratory failure.
