This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Many older patients experience a kind of ‘brain fog’ following surgery, in which cognition is impaired from lingering effects of anesthesia. It’s temporary, but can still be disruptive. Now, there is early evidence that one way to prevent such problems is to automate more aspects of anesthetic management during surgery. That’s the preliminary finding from a new randomized controlled trial appearing in the journal Anesthesiology. Researchers at a hospital in Belgium tested whether automating three aspects of anesthetic management -- anesthetic depth, cardiac blood flow, and protective lung ventilation -- improved performance on cognitive tests post-op, compared to when an anesthesiologist is in manual control. Going in, the idea was that machines could do an even better job than humans at keeping parameters within the recommended ranges, and this might lead patients to have less post-op cognitive impairment..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

In this episode, Hank talks about how nutty our world is via Buffers! He defines buffers and their compositions and talks about carbonate buffering systems in nature, acid rain, pH of buffers, and titration. Plus, a really cool experiment using indicators to showcase just how awesome buffers are.

This video demonstrates students measuring the alkalinity of a water sample, using an alkalinity test kit. The resource includes a video and a written transcript, and is supported by the Alkalinity Protocol in the GLOBE Teacher's Guide. This is one of seven videos on hydrology in a 24-part instructional video series describing scientific protocols used by GLOBE (Global Learning and Observation to Benefit the Environment), a worldwide, hands-on, K-12 school-based science education program.

This video introduces the measurement of dissolved oxygen in a water body as an important indicator of ecosystem health, and demonstrates students analyzing a water sample for dissolved oxygen. The resource includes a video and a written transcript, and is supported by the Dissolved Oxygen Protocol in the GLOBE Teacher's Guide. This is one of seven videos on hydrology in the 24-part instructional video series describing scientific protocols used by GLOBE (Global Learning and Observation to Benefit the Environment), a worldwide, hands-on, K-12 school-based science education program.

This video demonstrates students measuring the acidity of water, using pH indicator paper and a pH meter. The resource includes a video and a written transcript, and is supported by the Water pH Protocol in the GLOBE Teacher's Guide. This is one of seven videos on hydrology in the 24-part instructional video series describing scientific protocols used by GLOBE (Global Learning and Observation to Benefit the Environment), a worldwide, hands-on, K-12 school-based science education program.

This module includes an interactive acid-base titration that allows students to select an acid (general "strong" or several weak), initial concentration of the acid and base, and initial volume of the acid.  Then, students click on the virtual stopcock to add base.The curve is generated while the correct equation is highlighted for each part of the titration.

This course provides an introduction to the chemistry of biological, inorganic, and organic molecules. The emphasis is on basic principles of atomic and molecular electronic structure, thermodynamics, acid-base and redox equilibria, chemical kinetics, and catalysis.
In an effort to illuminate connections between chemistry and biology, a list of the biology-, medicine-, and MIT research-related examples used in 5.111 is provided in Biology-Related Examples.

This investigation is a laboratory activity in which the alkalinity of 2 types of substrates (carbonate vs. non-carbonate) are compared on the basis of titration. Students will reflect on the relationship of alkalinity and toxic heavy metals.
