The activities of the Vsr and MutH endonucleases of Escherichia coli are stimulated by MutL. The interaction of MutL with each enzyme is enhanced in vivo by 2-aminopurine treatment and by inactivation of the mutY gene. We hypothesize that MutL recruits the endonucleases to sites of DNA damage.

A 6-year-old Labrador retriever dog with a history of pneumonia was presented because of an acute onset of dull mentation and coughing. Diagnostic imaging and cytology revealed a pneumothorax, pneumomediastinum, and pleural effusion, consistent with pyothorax. The dog underwent exploratory sternotomy for lung lobectomy of the right cranial and middle lung lobes.

Optical tweezers, which leverage the forces exerted by radiation pressure, have emerged as a pivotal technique for precisely manipulating and analyzing microscopic particles. Since Arthur Ashkin's ground-breaking work in the 1970s and the subsequent development of the single-beam optical trap in 1986, the capabilities of optical tweezers have expanded significantly, enabling the intricate manipulation of biological specimens at the micro- and nanoscale. This review elucidates the foundational principles of optical trapping and their extensive applications in the biomedical sciences.

Farm biosecurity is valuable for reducing the indiscriminate use of antimicrobials. However, its relationship with antimicrobial usage can be difficult to assess because of multiple factors. This study evaluated the impact of biosecurity practices on productivity, frequency of antimicrobial use, and development of antimicrobial resistance.

Members of the KCNE family are accessory subunits that modulate voltage-gated potassium channels. One member, KCNE4, has been shown to inhibit the potassium ion current in these channels. However, little is known about the structure, dynamics, and mode of inhibition of KCNE4, likely due to challenges in overexpressing and purifying the protein.
