Summary
A rare uterine sarcoma metastasized in a rhesus monkey. This case highlights the importance of recognizing uterine tumors in non-human primates, aiding in early diagnosis and treatment strategies.
Area of Science:
- Veterinary Pathology
- Primate Oncology
- Comparative Oncology
Background:
- Malignant mesenchymal uterine tumors are infrequently reported in primates.
- Understanding uterine sarcoma in non-human primates is crucial for comparative oncology.
Observation:
- A 17-year-old rhesus monkey presented with symptoms including abdominal pain, nausea, anemia, and bloody vaginal discharge.
- Diagnostic laparoscopy revealed pelvic adhesions and ascites.
- Necropsy identified a large uterine tumor with metastases to the omentum.
Findings:
- Histological examination confirmed a sarcoma in both the uterus and metastases.
- The sarcoma exhibited scant connective tissue and well-differentiated cell nuclei.
Implications:
- This case expands the understanding of uterine sarcoma in rhesus monkeys.
- It underscores the need for vigilance in diagnosing uterine neoplasms in primates.
- Further research into primate uterine tumors can inform human cancer studies.

01:30Spontaneous and Induced Mutations
2.2K
Spontaneous mutations arise infrequently during DNA replication due to errors in the process. A key factor behind these errors is tautomeric shifts in nitrogenous bases, where bases transition from keto to enol forms or amino to imino forms. This shift can alter base-pairing rules, leading to mutations. Additionally, reactive oxygen species (ROS) arising from aerobic metabolism can damage DNA, resulting in depurination (loss of a purine base) or depyrimidination (loss of a pyrimidine base).

02:21Spontaneity
29.7K
A spontaneous process is one that occurs naturally under certain conditions. A nonspontaneous process, on the other hand, will not take place unless it is “driven” by the continual input of energy from an external source. Processes have a natural tendency to occur in one direction under a given set of conditions. Water will naturally flow downhill (spontaneous process), but uphill flow (nonspontaneous process) requires outside intervention such as the use of a pump. Iron exposed to...

01:16Uterine Tubes
2.2K
The uterine or fallopian tubes function as the conduit through which oocytes travel from the ovaries to the uterus. Each fallopian tube measures approximately 10 to 13 cm long and is anatomically divided into the infundibulum, ampulla, isthmus, and interstitial part (or intramural segment). The infundibulum is characterized by its funnel shape and features extensions called fimbriae which reach towards the peritoneal cavity. These fimbriae play a critical role during ovulation as they extend...

01:03Rous Sarcoma Virus (RSV) and Cancer
6.4K
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.

02:11Effects of Temperature on Free Energy
28.2K
The spontaneity of a process depends upon the temperature of the system. Phase transitions, for example, will proceed spontaneously in one direction or the other depending upon the temperature of the substance in question. Likewise, some chemical reactions can also exhibit temperature-dependent spontaneities. To illustrate this concept, the equation relating free energy change to the enthalpy and entropy changes for the process is considered:

02:49Second Law of Thermodynamics
26.9K
In the quest to identify a property that may reliably predict the spontaneity of a process, a promising candidate has been identified: entropy. Processes that involve an increase in entropy of the system (ΔS > 0) are very often spontaneous; however, examples to the contrary are plentiful. By expanding consideration of entropy changes to include the surroundings, a significant conclusion regarding the relation between this property and spontaneity may be reached. In thermodynamic models, the...
