Microbubbles in combination with focused ultrasound for the delivery of quercetin-modified sulfur nanoparticles through the blood brain barrier into the brain parenchyma and relief of endoplasmic reticulum stress to treat Alzheimer's disease.

The delivery of drugs across the blood-brain barrier (BBB) effectively and safely is one of the major challenges in the treatment of neurodegenerative diseases. In this work, we constructed a nano-system using microbubbles to promote the crossing of drugs across the BBB, where microbubbles in combination with focused ultrasound were used to mediate the transient opening of the BBB and delivery of nanomedicines. This system (Qc@SNPs-MB) was formed by embedding quercetin-modified sulfur nanoparticles (Qc@SNPs...

Interferons: a molecular switch between damage and repair in ageing and Alzheimer's disease.

Alzheimer's disease was first described over 100 years ago, yet it remains incurable and affects 44 million people worldwide. Traditionally, research has largely focused on the amyloid cascade hypothesis, but interest in the importance of inflammation in the progression of the disease has recently been increasing. Interferons, a large family of cytokines that trigger the immune system, are believed to play a crucial role in the pathology of Alzheimer's disease. This review focuses on how interferons affect ...

Histotripsy: The Next Generation of High-Intensity Focused Ultrasound for Focal Prostate Cancer Therapy.

This article reviews the most current methods and technological aspects of high-intensity focused ultrasound (HIFU), which is termed histotripsy. The rationale for focal therapy for prostate carcinoma rather than prostatectomy, which is being used extensively throughout Europe and Asia, is presented, and an argument for why HIFU is the modality of choice for primary therapy and recurrent disease is offered. The article presents a review of the technical advances including higher ultrasound beam energy than ...

Clinical and Radiographic Outcomes of Modified Unilateral Open-door Laminoplasty with Posterior Muscle-Ligament Complex Preservation for Cervical Spondylotic Myelopathy.

Glymphatics visualization after focused ultrasound induced blood-brain barrier opening in humans.

It is currently unclear whether the glymphatic system, a brain-wide interstitial fluid-cerebrospinal fluid exchange as described in rodents, exist in humans. Focal blood-brain barrier disruption using MR-guided focused ultrasound allows parenchymal penetration of gadobutrol contrast, creating an opportunity to study the glymphatics in vivo noninvasively. We describe patterns of contrast distribution in the perivascular space, subarachnoid space, and space surrounding large veins draining towards the dural s...

Low Intensity Focused Ultrasound Modulation of Vincristine Induced Neuropathy.

Previously, we showed internal low intensity focused ultrasound (liFUS) improves nociceptive thresholds in rats with vincristine-induced neuropathy (VIN) for 48-h post-treatment. Here, we perform more rigorous behavioral testing with the internal device and introduce external liFUS treatment. Behavioral testing confirmed VIN induced neuropathy (Von Frey fibers, VFF; hot plate, HPT; locomotion, OFT). This was followed by internal or external liFUS treatment (2.5 W or 8 W, for 3 min, respectively) to th...
