Traditional biological detection methods rely on signal amplification strategies such as enzymatic catalysis or nucleic acid amplification. However, their efficiency decreases in low-temperature environments, compromising their detection sensitivity. To break the loss of enzyme catalytic activity at low temperatures, research on cold-adaptive nanozymes has attracted much attention.

Background: The use of capturing devices may become required for the continued use desflurane. We tested the percentage of desflurane captured by a charcoal filter (CONTRAfluran)-workstation (Aisys) combination in vitro.
Methods: Desflurane in O2/air was administered via an Aisys workstation into a 2 L test lung that was insufflated with CO2 (160 mL/min).

In this research, nineteen (19) samples were collected and analyzed with the following objectives: to evaluate the activity concentration of radionuclides, assess gamma absorption, determine indoor radon concentration, and evaluate the public health impact of building materials used in Katsina State, Nigeria. The study aimed to provide critical data that would inform safe construction practices and regulatory compliance. Samples were sourced locally from various quarry sites, while materials such as cement, paint, tiles, and ceiling materials were purchased from local markets.

Many patients experience long-term cognitive dysfunction after subarachnoid hemorrhage (SAH), and effective treatments are currently lacking. Carbon dioxide (CO2), an inexpensive and easily produced gas, forms carbonic acid when dissolved in water. Studies have suggested that hypercapnia may have neuroprotective effects.
