Context: A previously healthy 40-year-old woman experienced a sudden complete tetraplegia (C8, AIS-A).

Findings: MRI revealed a C6/C7 disc herniation surrounded by an epidural haematoma.

Conclusion/clinical Relevance: Physicians must recognize acute, non-traumatic disc herniation as a potential cause of spinal cord injury, urging prompt diagnosis and intervention.

Inositol 1,3,4,5,6-pentakisphosphate 2-kinase (IPK1) catalyzes the final step in phytic acid (InsP) synthesis. In this study, the effects of OsIPK1 mutations on InsP synthesis, grain filling and their underlying mechanisms were investigated. Seven gRNAs were designed to disrupt the OsIPK1 gene via CRISPR/CAS9 system.

Thrombotic microangiopathy (TMA), characterized by microangiopathic hemolytic anemia, thrombocytopenia, and multisystem organ dysfunction, is a life-threatening disease. Patients with TMA who do not exhibit a severe ADAMTS-13 deficiency (defined as a disintegrin-like and metalloprotease with thrombospondin type 1 motif no. 13 activity ≥10%: TMA-13n) continue to experience elevated mortality rates.

The use of doubled haploid (DH) technology enables the development of new varieties of plants in less time than traditional breeding methods. In microspore embryogenesis (ME), stress treatment triggers microspores towards an embryogenic pathway, resulting in the production of DH plants. Epigenetic modifiers have been successfully used to increase ME efficiency in a number of crops.

Article Synopsis
  • Southeast Asian rainforest hunter-gatherers exhibit specific traits such as dark skin, short stature, woolly hair, and steatopygia (fat accumulation in hips), collectively referred to as the DSWS phenotype.
  • Researchers identified a genetic variation (R990G) in the calcium-sensing receptor gene that may be an adaptive response to their environment, particularly in terms of calcium regulation and overall metabolism.
  • Experiments using mice with the R990G variation showed lower calcium levels and increased body weight and fat, suggesting that these traits might have contributed to survival during times of nutritional stress in the rainforest.
