Wild, scenic, and toxic: Recent degradation of an iconic Arctic watershed with permafrost thaw.

The streams of Alaska's Brooks Range lie within a vast (~14M ha) tract of protected wilderness and have long supported both resident and anadromous fish. However, dozens of historically clear streams have recently turned orange and turbid. Thawing permafrost is thought to have exposed sulfide minerals to weathering, delivering iron and other potentially toxic metals to aquatic ecosystems.

Comparative Assessment of Whole Organ Tissue Processing Methods for the Isolation of Extracellular Vesicles From Intact Organs.

Extracellular vesicles (EVs) are small anuclear cellular membrane encapsulated fragments of importance for cellular interaction and transfer of information. These small vesicles, diverse in size and functionality, can be obtained from cells, tissues and bodily fluids. A complicated step for obtaining EVs from whole organs is understanding the optimal methodology for organ processing.

Ultrasound-Guided Steroid Injection for Low Back Pain Caused by Bilateral Pars Interarticularis Defects With Fluoroscopic Confirmation, A Case Report.

Background: Low back pain is a prevalent issue with various etiologies, one of which includes pars interarticularis (pars) defects. While traditional fluoroscopic guidance has been the standard for administering injections, both fluoroscopic and ultrasound-guided injections for the management of low back pain have been shown to be similar in efficacy. The benefits of ultrasound guidance include real-time visualization, reduced radiation exposure, and improved patient access.
