This study presents a novel method to provide efficient patient temperature control for cooling or warming patients. A single use, triple lumen device is placed into the esophagus, analogous to a standard orogastric tube, and connects to existing heat exchange units to perform automatic patient temperature management.

Regulating Temperature in the Lab: Applying Heat

2023
Although many experimental assays are performed at room temperature (RT; ~20-25°C), it is not uncommon for experiments, or parts of experiments, to require some type of temperature regulation. This video discusses the different reasons for and temperatures at which a scientist may want to “keep things warm”. For example, sometime, cells need to be cultured in an environment close to body temperature (~37°C), protein structure needs to be modified (>56°C), or reagents and solutions need to...

Local Heat Probe Assay: A Method to Assess Nociception of High Temperatures in Drosophila Larvae
0 Views •
2023
Drosophila larvae have dedicated sensory neurons–nociceptors–whose response to potentially harmful thermal stimuli triggers aversive–or so-called "nocifensive"–behaviors in the animal. This video describes a method to assess thermal nociception by recording larval behavior in response to local application of a heat probe onto the cuticle. This method is, therefore, called the local heat probe assay.

FAQs
A proportional-integral-derivative controller continuously compares the measured plate temperature with the selected setpoint and changes electrical power accordingly. Proportional action responds to the present difference, integral action addresses accumulated deviation, and derivative action can respond to the rate of change. Together, these feedback behaviors help maintain stability and repeatability during engineering processes.
Thermocouples and resistance temperature detectors provide the continuous temperature measurements required for feedback. The controller uses those measurements to determine whether the heated surface is above, below, or near its setpoint, then adjusts power to the resistive element. Reliable sensing therefore directly supports temperature accuracy, stable operation, and consistent experimental or manufacturing results.
Insulation reduces heat loss from the heated surface, allowing more of the supplied electrical power to support the intended temperature. Thermal design also affects how evenly heat is distributed across the plate. Improving these features can reduce temperature variation, increase control stability, and help samples or test materials experience more consistent processing conditions.
A basic setup establishes the required temperature setpoint, connects a temperature sensor such as a thermocouple or resistance temperature detector, and links the measurement to a feedback controller. The controller then regulates power delivered to the resistive heating element while the sensor reports the plate temperature continuously. This arrangement supports controlled heating and repeatable operation.
Engineers use controlled heated plates when temperature accuracy, stability, or repeatability affects the result. Relevant applications include material testing, chemical processing, electronics manufacturing, biological sample preparation, and laboratory heating. Feedback regulation is especially useful when a process must remain near a defined temperature instead of relying on a fixed or manually adjusted heat input.
Engineers can evaluate whether a process maintains its intended temperature, how consistently a material or sample experiences heating, and whether repeated runs produce comparable conditions. The system also supports attention to operational safety because temperature deviation can be detected through continuous measurement and addressed by adjusting power. These outcomes help connect thermal performance with process reliability.
