It is a subject of research in animals and human clinical trials. As of 2012, the lowest body temperature ever survived by a human being was 9 °C (48 °F) as part of a hypothermic circulatory arrest experiment to treat cancer in 1957. [33] [34] This temperature was reached without surgery, using external cooling alone. Similar low temperatures ...
The heart is at the top of the back, just behind the head, and the average heart rate is about 180 bpm under normal conditions. Daphnia spp., like many animals, are prone to alcohol intoxication, and make excellent subjects for studying the effects of the depressant on the nervous system due to the translucent exoskeleton and the visibly ...
Localized hyperthermia treatment is a well-established cancer treatment method with a simple basic principle: If a temperature elevation to 40 °C (104 °F) can be maintained for one hour within a cancer tumor, the cancer cells will be destroyed. [11] The schedule for treatments has varied between study centers.
Daphnia magna is widespread in the Northern Hemisphere and in particular in the holarctic. [2] It can be found in fresh and brackish water bodies of different sizes, from lakes to ponds and ephemeral rock pools near the sea. D. magna tolerates higher levels of salinity (up to one-fifth the salinity of sea water) than most other species of the ...
Hyperthermia; Other names: Overheating: An analog medical thermometer showing a temperature of 38.7 °C (101.7 °F): Specialty: Critical care medicine: Symptoms: Lack of perspiration, confusion, delirium, decreased blood pressure, increased heart rate and respiration rate, symptoms of dehydration
Daphnia lumholtzi is typically found in the warm, shallow regions [6] of bodies of water with larger surface areas. [7] While most species of Daphnia see high mortality at temperatures greater than 25 °C, [8] D. lumholtzi individuals can survive and reproduce at temperatures up to 30 °C, [8] [9] [10] with a thermal optimum occurring at 29 °C. [9]
Daphnia pulex. The genus Daphnia (Crustacea: Cladocera: Daphniidae) contains over 200 species of water fleas, many of which are in need of further taxonomic investigation (species inquirendae; marked with asterisks). [1]
On physical exam of a suspected HAPE patient the exam findings used to grade the severity are the heart rate, respiratory rate, signs of cyanosis, and severity of lung sounds. [8] Both symptoms and signs on physical exam can be used to evaluate a patient in the field. Chest X-rays are also used to evaluate the severity of HAPE when they are ...
