Background And Objectives: The mechanisms of lead placement error and brain shift in deep brain stimulation (DBS) remain poorly understood. Further understanding is critical as lead displacement >2 mm can lead to poor treatment efficacy. Differences between anesthesia and surgical techniques often vary significantly, making the cause of error challenging to ascertain.

Bone infections caused by Staphylococcus aureus may lead to an inflammatory condition called osteomyelitis, which results in progressive bone loss. Biofilm formation, intracellular survival, and the ability of S. aureus to evade the immune response result in recurrent and persistent infections that present significant challenges in treating osteomyelitis.

Article Synopsis
  • * Out of 129 patients, there was no significant difference in recurrence rates between those who received surgical adjuvants and those who did not, with overall recurrence rates of about 25%.
  • * The study also found that younger patients (under 6 years) had a higher likelihood of recurrence compared to older patients, suggesting age may be a more significant factor than the use of adjuvants.

Triple-negative breast cancer (TNBC) has a poor clinical outcome, due to a lack of actionable therapeutic targets. Herein we define lysosomal acid lipase A (LIPA) as a viable molecular target in TNBC and identify a stereospecific small molecule (ERX-41) that binds LIPA. ERX-41 induces endoplasmic reticulum (ER) stress resulting in cell death, and this effect is on target as evidenced by specific LIPA mutations providing resistance.

Prostate cancer (PCa) and breast cancer (BCa) are both hormone-dependent cancers that require the androgen receptor (AR) and estrogen receptor (ER, ESR1) for growth and proliferation, respectively. Endocrine therapies that target these nuclear receptors (NRs) provide significant clinical benefit for metastatic patients. However, these therapeutic strategies are seldom curative and therapy resistance is prevalent.

Poly(ethylene glycol) (PEG), a linear polymer known for its "stealth" properties, is commonly used to passivate the surface of biomedical implants and devices, and it is conjugated to biologic drugs to improve their pharmacokinetics. However, its antigenicity is a growing concern. Here, the antigenicity of PEG is investigated when assembled in a poly(oligoethylene glycol) methacrylate (POEGMA) "bottlebrush" configuration on a planar surface.
