During the 3 years of the trial (June, 1988--December, 1990), 128 patients underwent urgent diagnostic endoscopy and hemostasis for acute peptic-ulcer bleeding. In the first group consisting of 57 patients, hemostasis was carried out by thermocoagulation (heat probe), in the second one (54 patients) by injection sclerotherapy and in the third group, hemorrhage was controlled by a combination of heater probe and sclerotherapy. The first and second groups did not differ significantly in age, sex, hemoglobin values, size, location of an ulcer, and kind of bleeding lesions classified according to Forrest. The efficacy of thermocoagulation and injection sclerotherapy in the treatment of acute peptic-ulcer bleeding was compared. In the group of patients treated with the heater probe, the initial hemostasis was achieved in 56 (98%) patients, while rebleeding occurred in 6 (10.7%) patients. In the sclerotherapy group, the initial hemostasis was accomplished in 51 (94.4%) patients, while 8 (15.6%) patients experienced rebleeding. There was no statistically significant difference in ultimate hemostasis between the patients treated with heater probe (94.7%) and the sclerotherapy patients (88.8%). The incipient results of the treatment of bleeding peptic ulcers obtained by a combination of sclerotherapy and heater probe were extremely good, but the final conclusion will be brought after the research on a larger group of patients. The only patient that died during the treatment belonged to the sclerotherapy group.

In this work, we present an experimental approach for monitoring the temperature of submicrometric, real-time operating electrical circuits using luminescence thermometry. For this purpose, we utilized lanthanide-doped up-converting nanocrystals as nanoscale temperature probes, which, combined with a highly sensitive confocal photoluminescence microscope, enabled temperature monitoring with spatial resolution limited only by the diffraction of light. To validate our concept, we constructed a simple model of an electrical microcircuit based on a single silver nanowire with a diameter of approximately 100 nm and a length of about 50 µm, whose temperature increase was induced by electric current flow.

Since the coronavirus disease 2019 (COVID-19) pandemic, isothermal amplification techniques have attracted attention due to their higher sensitivity and specificity, compared with immunoassays, and their potential application for point-of-care testing (POCT). A requirement of isothermal amplification-based POCT kits is the inclusion of a heating source with an electrical power supply. We developed an amplification-based rapid kit, which is a portable and naked eye-detectable reverse transcriptase (RT)-recombinase polymerase amplification (RPA) kit.

Precise control of cellular temperature at the microscale is crucial for developing novel neurostimulation techniques. Here, the effect of local heat on the electrophysiological properties of primary neuronal cultures and HEK293 cells at the subcellular level using a cutting-edge micrometer-scale thermal probe, the diamond heater-thermometer (DHT), is studied. A new mode of local heat action on a living cell, thermal-capture mode (TCM), is discovered using the DHT probe.

Peptic ulcer bleeding is the most common cause of upper gastrointestinal bleeding, which has a high mortality risk. The standard therapy for acute peptic ulcer bleeding combines medication administration and endoscopic therapies. Both pharmacologic and endoscopic therapies have developed continuously in the past few decades.

Human skin has several receptors collaborating with the brain to provide appropriate "decisions" when applying stimuli. Several research articles state that biomimetic electronic skin (e-skin) is reportedly used for sensor-related applications and performs similarly to natural skin. However, research reporting the capability of the e-skin to make decisions and therefore react upon exposure to adverse conditions is still in its nascent stage.
