Separation Surgery Followed by Conformal Postoperative Spine Stereotactic Body Radiation Therapy Does Not Increase Risk of Adjacent Spine Level Progression in the Management of Spine Metastases.

Objectives: To determine if piecemeal separation surgery, in conjunction with smaller treatment volumes utilized with spine stereotactic radiation therapy (S-SBRT), increased the risk of adjacent level progression (ALP).

Methods: We performed a retrospective analysis of a prospectively maintained database of adult spine oncologic patients who underwent SBRT to the spine at University of Michigan from 2010 to 2021. We compared ALP in patients undergoing SBRT who had pretreatment surgery with those who did not.

Natural products and long non-coding RNAs in prostate cancer: insights into etiology and treatment resistance.

Globally, the incidence and death rates associated with cancer persist in rising, despite considerable advancements in cancer therapy. Although some malignancies are manageable by a mix of chemotherapy, surgery, radiation, and targeted therapy, most malignant tumors either exhibit poor responsiveness to early identification or endure post-treatment survival. The prognosis for prostate cancer (PCa) is unfavorable since it is a perilous and lethal malignancy.

Role of long non-coding RNAs and natural products in prostate cancer: insights into key signaling pathways.

Prostate cancer (PC) ranks among the most prevalent cancers in males. Recent studies have highlighted intricate connections between long non-coding RNAs (lncRNAs), natural products, and cellular signaling in PC development. LncRNAs, which are RNA transcripts without protein-coding function, influence cell growth, programmed cell death, metastasis, and resistance to treatments through pathways like PI3K/AKT, WNT/β-catenin, and androgen receptor signaling.

Recreating Silk's Fibrillar Nanostructure by Spinning Solubilized, Undegummed Silk.

The remarkable toughness (>70 MJ m) of silkworm silk is largely attributed to its hierarchically arranged nanofibrillar nanostructure. Recreating such tough fibers through artificial spinning is often challenging, in part because degummed, dissolved silk is drastically different to the unspun native feedstock found in the spinning gland. The present work demonstrates a method to dissolve silk without degumming to produce a solution containing undegraded fibroin and sericin.

A Case of Xylazine-Induced Necrotic Skin Ulcerations in an IV-Drug User in Florida.

Introduction: As illicit drug manufacturers find new ways to market their products and increase their profit margins, multiple contaminants have found their way into the illicit drug supply. The newest addition, xylazine, also known as "tranq," has spread through the city of Philadelphia and has recently been gaining ground across the United States, including in the state of Florida.

Case Presentation: This case describes a 37-year-old male with a significant past psychiatric history of severe polysubstance intravenous (IV) use, including fentanyl and methamphetamine.
