Examine the effects of focused ultrasound in combination with plasma radiofrequency ablation technology on the physiological stability and postoperative recovery of persistent strain rhinitis. For a control experiment, 90 patients with persistent strain rhinitis were chosen and split into two groups: the control group (CG) and the experimental group (EG). The CG used conventional radiofrequency ablation technology, while the EG used focused ultrasound technology combined with radiofrequency ablation technology to treat persistent strain rhinitis. Between the EG and the CG, compare and contrast the recovery of nasal symptoms, nasal signs, postoperative discomfort, and postoperative respiratory status. One quarter after surgery, there was a substantial difference in physical sign ratings between the EG and the CG, and a particularly significant difference was seen after six months of treatment. One year following surgery, there was a statistical difference between the EG and the CG in the comparison of effective rates at various intervals, with a P value of .013. At 6 months following surgery, the MTT times in the EG and CG for the comparison of nasal function were 12.63 2.65 and 17.68 2.84, respectively, with statistically significant differences. The difference between the EG and the CG in the MTR comparison is statistically significant. In the comparison of NNO values between the EG and the CG after different treatment times. The nitric oxide value of the EG patients decreased over time, with statistical significance one month after surgery and one year after surgery. It is evident from the comparison of various symptom efficacy rates that the EG has a higher treatment effectiveness rate than the CG, and the total treatment effect difference following surgery has statistical significance. Indicators for PONV, PA, directional ability, respiratory recovery, and olfactory recovery performed better in the EG than in the CG, and the differences were statistically significant. Focused ultrasound and plasma radiofrequency ablation technology have a good therapeutic impact in the treatment of persistent strain rhinitis and can significantly reduce MTT. This technology can effectively improve symptoms such as nasal congestion, nasal flow, and headache in patients, and the therapeutic effect is long-lasting. The hospitalization time after treatment is significantly shortened.

BACKGROUND: Myofascial pain syndrome (MPS) is a particular type of temporomandibular joint disorder. Research findings comparing various treatment approaches are scarce and controversial. Therefore, this study aimed to compare the effectiveness of ultrasound therapy, stabilization splint, TheraBite device, and masticatory muscle exercises in reducing pain intensity and improving mandibular mobility in patients with MPS.
METHODS: It was a single-blind, randomized, parallel-group, active-controlled trial that took place between April 2023 and October 2023 at the Department of Fixed Prosthodontics, Damascus University. Patients older than 18 years old with myofascial pain accompanied by limited jaw opening and pain lasting for at least 6 months were included. Eighty patients were randomly assigned into four groups using online randomization software: ultrasound therapy, stabilization splint, TheraBite device, and masticatory muscle exercises. Only outcome assessors were masked to treatment allocation. The exercise regimen was the exercise program for patients with TMD. The following primary outcome measures were considered at the baseline (t0), at the first (t1), second (t2), and fourth (t3) week of treatment, and at the second (t4) and fifth (t5) month of follow-up: pain intensity using the visual analogue scale, maximum interincisal opening, right lateral movement, and left lateral movement measured in millimeters.
RESULTS: The pain level changed from severe to mild at t3 in ultrasound therapy, stabilization splint, and TheraBite device groups. In the masticatory muscle exercises group, it changed to moderate, with a significant difference between ultrasound therapy (p = 0.012) and stabilization splint (p = 0.013) groups. In addition, the mandibular mobility continued to improve at the subsequent follow-up periods (t4 and t5).
CONCLUSIONS: All therapies are equally effective after 5-month follow-up. However, ultrasound therapy and stabilization splints have the benefit of achieving rapid improvement.

BACKGROUND: Breast cancer ranks second as the most common malignancy globally, after lung cancer. Among the various subtypes of breast cancer, HER2 positive breast cancer (HER2 BC)poses a particularly challenging prognosis due to its heightened invasiveness and metastatic potential. The objective of this study was to construct a composite piezoelectric nanoparticle based on poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) for imaging and treatment of HER2 BC.
METHODS: By reshaping the crystal structure of P(VDF-TrFE) piezoelectric nanoparticles, improving hydrophilicity, and incorporating imaging capabilities, we developed piezoelectric composite nanoparticles (PGd@tNBs) that integrate imaging and therapeutic functions. The in vitro characterization encompassed the assessment of piezoelectric properties, hydrophilicity, imaging performance, and therapeutic efficacy of these particles. The targeting and therapeutic effectiveness of PGd@tNBs particles were further validated in the SK-BR3 cell line and subsequently confirmed in HER2-positive tumor-bearing mice.
RESULTS: The nanoparticle demonstrated excellent biocompatibility and impressive multimodal imaging performance. Magnetic resonance imaging (MRI) observations revealed significant accumulation of PGd@tNBs particles in the HER2 positive tumor, exhibiting superior contrast-enhanced ultrasound performance compared to traditional ultrasound contrast agents, and small animal in vivo imaging showed that PGd@tNBs particles were primarily excreted through respiration and urinary metabolism. Piezoforce Microscopy characterization highlighted the outstanding piezoelectric properties of PGd@tNBs particles. Upon targeted binding to HER2-BC, ultrasound stimulation influenced the cell membrane potential, leading to reversible electroporation. This, in turn, affected the balance of calcium ions inside and outside the cells and the mitochondrial membrane potential. Following ingestion by cells, PGd@tNBs, when exposed to ultrasound, triggered the generation of reactive oxygen species (ROS), resulting in the consumption of glutathione and superoxide dismutase and achieving sonodynamic therapy. Notably, repeated ultrasound stimulation, post PGd@tNBs particles binding and entry into cells, increased ROS production and elevated the apoptosis rate by approximately 45%.
CONCLUSIONS: In conclusion, the PGd@tNBs particles developed exhibit outstanding imaging and therapeutic efficacy, holding potential for precise diagnosis and personalized treatment of HER2 BC.

UNASSIGNED: Hemiplegic shoulder pain (HSP) is a prevalent clinical manifestation following stroke, often causing considerable discomfort and disability. Various therapeutic approaches have been developed to address HSP.
UNASSIGNED: This study aimed to compare the effectiveness of HILT versus US therapy in alleviating HSP in stroke patients.
UNASSIGNED: A double-blind randomized controlled trial enrolled stroke patients with HSP within one year post-onset. Participants were randomly assigned to HILT (with sham US) or US therapy (with sham HILT). Both groups received 10-minute sessions of their assigned therapy modality along with daily shoulder range of motion (ROM) exercises 5 times per week over two consecutive weeks. Pain reduction was the primary outcome, with shoulder ROM as secondary outcomes.
UNASSIGNED: Thirty patients (11 women, 19 men; mean age: 60.80 ± 11.51 years) were included. After the two-week intervention, significant improvements were observed in pain reduction at rest and during motion in the HILT group, and in pain reduction during motion and shoulder internal rotation in the US group compared to pre-treatment values within each group. However, there was no significant difference between the HILT and US therapy groups in any evaluated parameter.
UNASSIGNED: Comparable efficacy was found between HILT and US therapy in reducing pain and improving shoulder ROM for HSP in stroke patients. Both modalities, when combined with shoulder ROM exercises, offer viable options for managing HSP in this population. Further research with larger sample sizes is needed to validate these findings and explore long-term outcomes.

Wound infections, especially those caused by pathogenic bacteria, present a considerable public health concern due to associated complications and poor therapeutic outcomes. Herein, we developed antibacterial nanoparticles, namely, PGTP, by coordinating guanidine derivatives with a porphyrin-based sonosensitizer. The synthesized PGTP nanoparticles, characterized by their strong positive charge, effectively disrupted the bacterial biosynthesis process through charge interference, demonstrating efficacy against both Gram-negative and Gram-positive bacteria. Additionally, PGTP nanoparticles generated reactive oxygen species under ultrasound stimulation, resulting in the disruption of biofilm integrity and efficient elimination of pathogens. RNA-seq analysis unveiled the detailed mechanism of wound healing, revealing that PGTP nanoparticles, when coupled with ultrasound, impair bacterial metabolism by interfering with the synthesis and transcription of amino acids. This study presents a novel approach to combatting wound infections through ultrasound-driven charge-interfering therapy, facilitated by advanced antibacterial nanomaterials.

The integration of sonodynamic therapy (SDT) with cuproptosis for targeted cancer treatment epitomizes a significant advancement in oncology. Herein, we present a dual-responsive therapeutic system, \"CytoNano\", which combines a cationic liposome infused with copper-nitride nanoparticles and oxygen-rich perfluorocarbon (Lip@Cu3N/PFC-O2), all enveloped in a biomimetic coating of neutrophil membrane and acid-responsive carboxymethylcellulose. CytoNano leverages the cellular mimicry of neutrophils and acid-responsive materials, enabling precise targeting of tumors and their acidic microenvironment. This strategic design facilitates the targeted release of Lip@Cu3N/PFC-O2 within the tumor, enhancing cancer cell uptake and mitochondrial localization. Consequently, it amplifies the therapeutic efficacy of both Cu3N-driven SDT and cuproptosis while preserving healthy tissues. Additionally, CytoNano\'s ultrasound responsiveness enhances intratumoral oxygenation, overcoming physiological barriers and initiating a combined sonodynamic-cuproptotic effect that induces multiple cell death pathways. Thus, we pioneer a biomimetic approach in precise sonodynamic cuproptosis, revolutionizing cancer therapy.

Here we report the effects of low-intensity pulsed ultrasound (LIPUS) on symptoms in peripheral arterial disease patients with Buerger disease. A double-blinded and randomized study with active and inactive LIPUS was conducted. We assessed symptoms in leg circulation during a 24-week period of LIPUS irradiation in 12 patients with Buerger disease. Twelve patients without LIPUS irradiation served as controls. The pain intensity on visual analog score was significantly decreased after 24-week LIPUS treatment. Skin perfusion pressure was significantly increased in patients who received LIPUS treatment. There was no significant difference in symptoms and perfusion parameters in the control group. No severe adverse effects were observed in any of the patients who underwent LIPUS treatment. LIPUS is noninvasive, safe and effective option for improving symptoms in patients with Buerger disease.

OBJECTIVE: This study investigated the magnitude, direction, and temporal aspects of the force applied during instrumentation with a piezoelectric ultrasonic periodontal scaler, compared this force with recommendations in the literature, and assessed the influence of the profession (dentist or dental hygienist) and calculus hardness.
METHODS: The force applied by ten dental hygienists and six dentists during debridement of comparatively soft and hard artificial dental calculus with a piezoelectric ultrasonic scaler was recorded in-vitro. The total force and its components in three axes were statistically analysed.
RESULTS: During debridement of soft artificial dental calculus, the mean total force applied by dental hygienists was 0.34 N (± 0.18 N, range: 0.13 N to 0.59 N) and by dentists 0.28 N (± 0.33 N, range: 0.06 N to 0.95 N), and the total force exceeded 0.5 N approximately 23% and 14% of the time for dental hygienists and dentists, respectively. During debridement of hard artificial dental calculus, the mean total force applied by dental hygienists was 0.63 N (± 0.40 N, range: 0.28 N to 1.64 N) and by dentists 0.57 N (± 0.17 N, range: 0.34 N to 0.76 N); the total force exceeded 0.5 N more than half of the time for both professions. On average, dental hygienists applied 1.85x (p = 0.04) and dentists 2.04x (p = 0.06) higher force on hard than on soft artificial calculus. However, dental hygienists and dentists used similar forces during the debridement of both hard (p = 1.00) and soft (p = 0.26) calculus.
CONCLUSIONS: The force applied during the debridement of hard artificial dental calculus was statistically significantly higher than during the debridement of soft artificial dental calculus. No statistically significant difference between dentists and dental hygienists was found. The force applied by both groups on soft and hard artificial dental calculus frequently exceeded recommended values.

UNASSIGNED: This study aimed to investigate the feasibility, efficacy, and safety of focused ultrasound (FUS) for the treatment of vulvar low-grade squamous intraepithelial lesions (VLSIL) with persistent symptoms.
UNASSIGNED: This retrospective analysis included 24 VLSIL patients who underwent FUS treatment. At each follow-up visit, the clinical response was assessed including changes in symptoms and signs. In addition, the histological response was assessed based on the vulvar biopsy results of the 3rd follow-up. Clinical and histological response were assessed to elucidate the efficacy.
UNASSIGNED: A total of 22 patients completed follow-up and post-treatment pathological biopsies. After treatment, the clinical scores of itching decreased from 2.55 ± 0.51 to 0.77 ± 0.81 (p < 0.05). Furthermore, the clinical response rate and histological response rate were 86.4% and 81.8%, respectively. Only two cured patients indicated recurrence in the 3rd and 4th year during the follow-up period and achieved cure after re-treatment. In terms of adverse effects, only one patient developed ulcers after treatment, which healed after symptomatic anti-inflammatory treatment without scarring, and no other treatment complications were found in any patients. None of the patients developed a malignant transformation during the follow-up period.
UNASSIGNED: This study revealed that FUS is feasible, effective, and safe for treating VLSIL patients with persistent symptoms, providing a new solution for the noninvasive treatment of symptomatic VLSIL.
