Evaluation of the efficacy of a novel lumbar exoskeleton with multiple interventions for patients with lumbar disc herniation: a multicenter randomized controlled trial of non-inferiority.

Background: Lumbar disc herniation (LDH) occurs when the nucleus pulposus or annulus fibrosus protrudes into the intervertebral space, potentially compressing nerve roots and causing symptoms such as sciatica, restricted mobility, and lower extremity weakness. The development of portable lumbar exoskeleton devices offers a new approach, combining traction, range of motion (ROM) exercises, and resistance training in a single system, potentially reducing treatment complexity and enhancing LDH patient outcomes.

Objective: This study aims to evaluate the efficacy and safety of a novel lumbar exoskeleton device compared to traditional traction methods combined with rehabilitation therapy for patients with LDH.

Targeting intracellular cancer proteins with tumor-microenvironment-responsive bispecific nanobody-PROTACs for enhanced therapeutic efficacy.

Proteolysis targeting chimeras (PROTACs) are pivotal in cancer therapy for their ability to degrade specific proteins. However, their non-specificity can lead to systemic toxicity due to protein degradation in normal cells. To address this, we have integrated a nanobody into the PROTACs framework and leveraged the tumor microenvironment to enhance drug specificity.

Real-World Outcomes in Patients With Metastatic Renal Cell Carcinoma Treated With First-Line Nivolumab Plus Ipilimumab in the United States.

Synthetic cannabinoids (SCs) are an evolving class of new psychoactive substances (NPS) with structurally various compounds that are increasing over the past few years. Therefore, they are initially hard to identify because of the lack of analytical information. Moreover, there is little to no information regarding the pharmacology of these compounds despite human abuse.

Young and naïve B cells are a diagnostic pitfall in pediatric tonsillectomies.

Tonsillar marginal zone hyperplasia may mimic mucosa-associated lymphoid tissue lymphoma, a rare diagnosis in children. Histologically, both entities can demonstrate expansion of the marginal zone with disruption of follicular architecture. However, marginal zone hyperplasia may appear polyclonal by flow cytometry.

Resting-state fNIRS reveals changes in prefrontal cortex functional connectivity during TENS in patients with chronic pain.

Transcutaneous electrical nerve stimulation (TENS) has been used to treat chronic pain. However, the potential efficacy and mechanism of the effect of applying TENS for a short time in chronic pain patients remains unclear. To identify the effect of short-term TENS on chronic pain patients and to clarify the mechanism of the effect, we investigated abnormalities of functional connectivity (FC) within the prefrontal cortex (PFC) using resting-state functional near-infrared spectroscopy (rs-fNIRS).

BSC2 modulates AmB resistance via the maintenance of intracellular sodium/potassium ion homeostasis in Saccharomyces cerevisiae.

Previous studies on BSC2 have shown that it enhances yeast cell resistance to AmB via antioxidation and induces multidrug resistance by contributing to biofilm formation. Herein, we found that BSC2 overexpression could reverse the sensitivity of pmp3Δ to AmB and help the tested strains restore the intracellular sodium/potassium balance under exposure to AmB. Meanwhile, overexpression of the chitin gene CHS2 could simulate BSC2 to reverse the sensitivity of pmp3Δ and nha1Δ to high salt or AmB.
