Meristems and Plant Growth

49.4K
Plants grow throughout their lives; this is called indeterminate growth, and it distinguishes plants from most animals. Although certain parts of plants stop growing (e.g., leaves and flowers), others grow continuously—like roots and stems.

Embryonic Stem Cells

32.4K
Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Induced Pluripotent Stem Cells

28.0K
Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...

Plant Tissue Culture

Plant tissue culture is widely used in both primary and applied science. Applications range from plant development studies to functional gene studies, crop improvement, commercial micropropagation, virus elimination, and conservation of rare species.

Chromatin Position Affects Gene Expression02:35

Chromatin Position Affects Gene Expression

24.8K
Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences  access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area. 
Topologically Associated Domains (TADs)
The 3-dimensional positioning of chromatin in the nucleus influences the...

Primary and Secondary Growth in Roots and Shoots

60.4K
Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Summary

Sinonasal undifferentiated carcinoma (SNUC) often presents late with poor prognosis. Early diagnosis and multimodality treatment, potentially including neoadjuvant chemotherapy, are crucial for managing this rare cancer.

Area of Science:

  • Oncology
  • Otorhinolaryngology
  • Head and Neck Surgery

Background:

  • Sinonasal undifferentiated carcinoma (SNUC) is a rare and aggressive malignancy.
  • SNUC typically presents at an advanced stage, associated with a poor prognosis and high rates of recurrence and metastasis.

Purpose of the Study:

  • To comprehensively review recent literature on the diagnosis and management of SNUC.
  • To emphasize the importance of differentiating SNUC from other sinonasal malignancies for appropriate treatment planning.

Main Methods:

  • Literature review focusing on recent advances in SNUC diagnosis and treatment.
  • Analysis of current therapeutic strategies, including surgery, radiation, and chemotherapy.

Main Results:

  • SNUC diagnosis and management remain challenging due to its aggressive nature and late presentation.
  • Multimodality treatment is the standard approach, with neoadjuvant chemotherapy showing potential for improved outcomes.
  • Despite advances, survival rates for SNUC remain poor, highlighting the need for further research.

Conclusions:

  • Accurate differentiation from other sinonasal cancers is critical for effective SNUC management.
  • Further investigation into induction chemotherapy followed by local therapy is warranted to improve patient outcomes.
  • Continued research into novel therapeutic strategies is essential for enhancing the prognosis of SNUC patients.
