Apoptosis propagates through the cytoplasm as trigger waves
Science, 2018 Visualizing a traveling wave of cell death When diffusion is too slow for communication over long distances, cells can use waves of chemical activity. By using fluorescent probes and microscopy, Cheng and Ferrell show that in frog eggs (which are very ...

Parathyroid Adenoma Completely Impacted within the Thyroid Gland: A Case Report [PDF]
Journal of Clinical and Diagnostic Research, 2016 Ectopic parathyroid adenoma can be seen in various locations. Sometimes ultrasound and even fine needle aspiration studies cannot distinguish this lesion from thyroid lesions. A 29-year-old woman with a prominent nodule of left thyroid lobe was referred

Lariat intronic RNAs in the cytoplasm of vertebrate cells
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Introns are noncoding DNA sequences interspersed among the coding sequences of genes. Shortly after transcription, the intronic sequences are spliced out of the primary RNA transcript as lariat RNAs (circular molecules with a short tail ...

Superdiffusion dominates intracellular particle motion in the supercrowded cytoplasm of pathogenic Acanthamoeba castellanii [PDF]
Scientific Reports, 2015 Acanthamoebae are free-living protists and human pathogens, whose cellular functions and pathogenicity strongly depend on the transport of intracellular vesicles and granules through the cytosol.
