Short-distance Transport of Resources02:12

Short-distance Transport of Resources

17.7K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

Power System Three-Phase Short Circuits

551
Determining the subtransient fault current in a power system involves representing transformers by their leakage reactances, transmission lines by their equivalent series reactances, and synchronous machines as constant voltage sources behind their subtransient reactances. In this analysis, certain elements are excluded, such as winding resistances, series resistances, shunt admittances, delta-Y phase shifts, armature resistance, saturation, saliency, non-rotating impedance loads, and small...

Three-Phase Short Circuit—Unloaded Synchronous Machine01:21

Three-Phase Short Circuit—Unloaded Synchronous Machine

688
Conducting a three-phase short circuit test on an unloaded synchronous machine helps understand its impact on the system. The AC fault current's oscillogram, with the DC offset removed, reveals that the waveform amplitude decreases from an initially high value to a steady-state level for one phase of the machine.
This behavior occurs due to the magnetic flux produced by the short-circuit armature currents. Initially, these currents follow high-reluctance paths but eventually shift to...

Tumor Immunotherapy01:27

Tumor Immunotherapy

1.9K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Tumor Progression02:07

Tumor Progression

7.4K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

The Tumor Microenvironment02:17

The Tumor Microenvironment

7.8K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

  • Immunology
  • Oncology
  • Cell Biology

Background:

  • Macrophages are crucial for tissue homeostasis and immunity.
  • In cancer, tumor-associated macrophages (TAMs) drive inflammation and tumor progression.
  • TAMs contribute to therapeutic resistance and immune suppression.

Purpose of the Study:

  • To elucidate the multifaceted role of TAMs in cancer.
  • To explore TAMs' involvement in chemo- and radiotherapy resistance.
  • To review strategies targeting TAMs for cancer therapy.

Main Methods:

  • Literature review on macrophage biology and cancer immunology.
  • Analysis of studies investigating TAMs' functions in the tumor microenvironment.
  • Examination of therapeutic approaches targeting TAMs.

Main Results:

  • TAMs stimulate cancer cell proliferation and angiogenesis.
  • TAMs are key mediators of resistance to chemotherapy and radiotherapy.
  • TAMs suppress anti-tumor immune responses.

Conclusions:

  • Understanding TAMs is critical for cancer treatment.
  • Targeting TAMs, directly or via repolarization, is a viable anticancer therapeutic strategy.
  • Repolarizing TAMs to a tumoricidal phenotype holds significant therapeutic potential.
