Self-driven disposable sensor for easy measurement of blood glucose levels at home

Electrochemical biosensors utilize biomolecules, such as enzymes and antibodies, as bioreceptors that recognize specific substances in a sample. This recognition generates an electrical signal that provides information about what is present and in what quantity. For instance, to determine the concentration of glucose in the blood, an electrochemical sensor with an enzyme that selectively recognizes glucose is used. However, this type of sensor usually requires a dedicated electrode and a device to control the reaction that takes place at the electrode.

Hormone therapy increases lumbar spine bone mineral density, protects against bone loss

As the population continues to age, there is greater focus on bone health and minimizing fractures to maintain mobility. A new study suggests that various types of hormone therapies not only increase lumbar spine bone mineral density (BMD) in postmenopausal women but also protect against bone loss, even after hormones have been discontinued. Study results are published online in Menopause.

Researchers identify the standard for gallbladder cancer surgery

The quality of surgery can drastically influence both short- and long-term postoperative outcomes and is a crucial consideration in studies that assess surgical outcomes. One approach for developing accurate quality measures is benchmarking, a quality-improvement process in which the best possible outcomes are identified to serve as a point of reference against which performance can be compared.
