Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

6.3K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Primary Active Transport01:47

Primary Active Transport

197.4K
In contrast to passive transport, active transport involves a substance being moved through membranes in a direction against its concentration or electrochemical gradient. There are two types of active transport: primary active transport and secondary active transport. Primary active transport utilizes chemical energy from ATP to drive protein pumps that are embedded in the cell membrane. With energy from ATP, the pumps transport ions against their electrochemical gradients—a direction...

Primary and Secondary Growth in Roots and Shoots03:02

Primary and Secondary Growth in Roots and Shoots

60.3K
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.

Primary Distribution01:28

Primary Distribution

534
Primary distribution systems deliver electrical power from substations to consumers through various voltage classes, with 15-kV class voltages being predominant among U.S. utilities. Older 2.5- and 5-kV classes are being replaced by 15-kV primaries, while higher 25- to 34.5-kV classes are used in high-density urban areas and rural regions with long feeders. Three-phase, four-wire multigrounded systems are widely employed for balanced power delivery, using the neutral wire as a grounding point.

Primary Production01:06

Primary Production

25.1K
The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.

    Area of Science:

    • Pediatric Oncology
    • Cancer Biology
    • Tumorigenesis

    Background:

    • Ewings sarcoma (EWS) comprises a group of small, round, blue cell tumors.
    • These tumors exhibit varying degrees of neuroectodermal differentiation.
    • EWS predominantly affects children and young adults.

    Purpose of the Study:

    • To describe the key characteristics of Ewings sarcoma (EWS) family tumors.
    • To highlight the incidence and demographic distribution of EWS.
    • To identify the proportion of extraskeletal EWS cases.

    Main Methods:

    • Review of epidemiological data on Ewings sarcoma.
    • Analysis of tumor differentiation markers.
    • Classification of tumor location (skeletal vs. extraskeletal).

    Main Results:

    • Ewings sarcoma (EWS) shows a peak incidence in pediatric and young adult populations.
    • Tumors display a spectrum of neuroectodermal differentiation.
    • Approximately 10-20% of all EWS cases are classified as extraskeletal.

    Conclusions:

    • Ewings sarcoma (EWS) is a distinct tumor type primarily affecting younger individuals.
    • Understanding the differentiation and location is crucial for diagnosis and treatment.
    • Extraskeletal EWS represents a significant subset requiring specific consideration.
