2019
A novel sample holder for macromolecular X-ray crystallography along with a suitable handling protocol is presented. The system allows crystal growth, crystal soaking and in situ diffraction data collection at both, ambient and cryogenic temperature without the need of any crystal manipulation or mounting.

Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

Charles Taylor and John Marshall explain the utility of mathematical modeling for evaluating the effectiveness of population replacement strategy. Insight is given into how computational models can provide information on the population dynamics of mosquitoes and the spread of transposable elements through A. gambiae subspecies. The ethical considerations of releasing genetically modified mosquitoes into the wild are discussed.

2017
Full-root aortic valve replacement by stentless aortic xenograft is a viable option in patients with small aortic roots. We describe, a technique for the full-root implantation of stentless aortic xenografts, with emphasis on the management of the proximal suture line and coronary anastomoses, and discuss its limitations and alternative options.
FAQs
Fit and tension determine whether the supported device remains secure without creating unnecessary pressure. A correctly sized holder should accommodate the device and maintain stable positioning, while insufficient tension can allow loosening or displacement. Excessive or poorly distributed tension may contribute to discomfort or pressure injury, so assessment guides adjustment.
Skin assessment helps identify irritation or pressure effects that could worsen if a new holder is applied without correcting the underlying fit or tension. Examining the device and surrounding area also helps detect contamination, looseness, or damage. These checks support a safer exchange and reduce risks associated with impaired skin protection and unstable positioning.
Replacement becomes appropriate when the holder is worn, contaminated, loose, damaged, or poorly fitting. Adhesives, straps, and other support materials may lose effectiveness or become soiled during care. Acting on these findings helps preserve secure positioning, patient comfort, reliable access, and unobstructed device function rather than waiting for accidental displacement.
During Holder Replacement, the existing support should be removed carefully while the medical device remains undisturbed. The clinician then selects a correctly sized replacement, applies it with appropriate tension, and avoids obstructing the device or its access. A controlled sequence limits movement during the exchange and supports stable positioning afterward.
After application, confirm that the holder is stable, the device remains correctly positioned, and access and function are unobstructed. The patient’s comfort and the surrounding skin also require attention, because a secure result is not adequate if the replacement creates irritation or excessive pressure. These checks determine whether further adjustment is needed.
Timely Holder Replacement is especially relevant when adhesives, straps, or support materials become loose, damaged, or soiled. Regular assessment allows care teams to intervene before these changes contribute to displacement, discomfort, pressure injury, skin irritation, or infection risk. This makes replacement part of ongoing routine care rather than an isolated response to failure.
