Effects of radial extracorporeal shockwave therapy versus high intensity laser therapy in individuals with plantar fasciitis: A randomised clinical trial
This study aimed to compare the effects of radial extracorporeal shockwave therapy (rESWT) to the effects of high-intensity laser therapy (HILT) in the treatment of individuals with plantar fasciitis. Thirty-two individuals with unilateral plantar fasciitis were randomized into two groups: rESWT and HILT. In each group, the individuals underwent the intervention two sessions per week, for three weeks. Outcome measures included morning pain, resting pain, pain at 80 newtons (N) pressure, skin blood flow and temperature, plantar fascia (PF) and flexor digitorum brevis (FDB) thickness, and Foot Function Index (FFI).

Photothermal treatment of glioblastoma cells based on plasmonic nanoparticles
AbstractPhotothermal therapy based on plasmonic gold nanoparticles is considered a promising approach for cancer treatment. Here, we investigate the in vitro photothermal effect of 30-nm gold nanoparticles, optically excited with a 532-nm continuous laser, on the U87MG malignant glioblastoma cells, and demonstrate the role of nanoparticle concentration and exposure power density in achieving its optimum performance. Laser-induced collective oscillation of electrons in plasmonic gold nanoparticles is employed to generate localized heat to denature tumor cells. Optical spectroscopy is used to measure the plasmonic band of na...

Time-dependent photobiomodulation management of neuropathic pain induced by spinal cord injury in male rats
AbstractNeuropathic pain (NP) following spinal cord injury (SCI) often lasts for a long time and causes a range of problems that reduce the quality of life. Current treatments are not generally effective; however, photobiomodulation therapy (PBMT) has made some progress in this area. Due to the novelty of this treatment, standard therapeutic protocols have not yet been agreed upon. In the present study, we compare the analgesic effect of two PBMT protocols (2 and 4 weeks of radiation). A total of thirty-two adult male Wistar rats were divided into four groups: control, SCI, 2 W PBMT, and 4 W PBMT. SCI was induced by an ane...

Case –control study analyzing the relationship between oral microcirculation and oral mucositis and pain in patients under antineoplastic therapy
AbstractThe study aimed to evaluate the relation between microcirculation of the genian region using laser Doppler flowmetry and oral mucositis (OM) and pain in individuals undergoing antineoplastic therapy. A case –control clinical study was conducted with the participants divided into three groups: chemotherapy (CTG), radiation therapy and chemotherapy group (RCTG), and control group (CG). Pain was assessed by visual analog scale; OM was classified by oral mucositis assessment and WHO scales. The blood flo w was assessed by laser Doppler flowmetry. Kruskal–Wallis statistical test, Friedman test, and Spearman test wer...

Office-based 532-nm KTP laser as a therapeutic modality for recurrent laryngeal papillomatosis: efficacy and relative factors
This study aims to investigate the efficacy of office-based potassium-titanyl-phosphate (KTP) 532-nm laser in the management of recurrent laryngeal papillomatosis (RLP) following other treatments. A retrospective assessment was performed on 55 patients in 259 cases of RLP between 2012 and 2019. Derkay scores were obtained for all patients who underwent 532-nm KTP laser procedure (6 W of power with a continuous output mode) prior to treatment and after treatment. Analysis of parameters is based on the distribution characteristics of data. An ordinal logistic regression was also performed. Patients received a median of 3 (ra...

Effect of photobiomodulation adjunct to periodontal therapy on individuals with type 2 diabetes mellitus regarding periodontal clinical parameters: a systematic review and meta-analysis
AbstractThe purpose of this study is to evaluate the scientific evidence on the impact of photobiomodulation adjunct to non-surgical periodontal treatment on individuals with type 2 diabetes mellitus (T2DM). The Preferred Reporting Items for Systematic Reviews and Meta-analyses statement was followed. A protocol was registered in the International Prospective Registry of Systematic Reviews (PROSPERO #CRD42022310756). The research was carried out in seven databases, with no restrictions regarding the year of publication.

Porphin e6 complex loaded with gold nanorod mesoporous silica enhances photodynamic therapy in ovarian cancer cells in vitro
AbstractA growing amount of experimental evidence has proven that the application of gold nanorods (AuNRs) in photodynamic therapy (PDT) can significantly enhance its therapeutic efficacy. The aim of this study was to establish a protocol for investigating the effect of gold nanorods loaded with the photosensitizer chlorin e6 (Ce6) on photodynamic therapy in the OVCAR3 human ovarian cancer cell line in vitro and to determine whether the PDT effect was different from that of Ce6 alone. OVCAR3 cells were randomly divided into three groups: the control group, Ce6-PDT group, and AuNRs@SiO2@Ce6-PDT group. Cell viability was mea...

Split-face comparison of hydroquinone 4% plus nitrogen plasma vs. hydroquinone 4% alone in the treatment of melasma
AbstractTreatment of skin diseases is important yet challenging. One of the most common skin diseases in women is melasma, which features acquired facial hyperpigmentation. We studied the effect of cold atmospheric nitrogen plasma on this disease. To characterize the nitrogen plasma, we obtained the relative intensity of the species and the plasma temperature and skin temperature during processing at different input powers and gas flows. Patients complaining of melasma were treated with hydroquinone on both sides of the face, and one side was randomly selected for additional nitrogen plasma therapy. Eight treatment sess...

Photobiomodulation therapy reverses spermatogenesis arrest in hyperthermia-induced azoospermia mouse model
This study aimed at evaluating the effect of PBMT on the improvement of spermatogenesis in mouse models of hyperthermia-induced azoospermia. A total of 32 male NMRI mice were equally divided into four groups consisting of control, hyperthermia, hyperthermia + Laser 0.03 J/cm2, and hyperthermia + Laser 0.2 J/cm2. To induce scrotal hyperthermia, mice were anesthetized and placed in a hot water bath at 43 °C for 20 min for 5 weeks. Then, PBMT was operated for 21 days using 0.03 J/cm2 and 0.2 J/cm2 laser energy densities in the Laser 0.03 and Laser 0.2 groups, respectively. Results revealed that PBMT with lower intensity (0.0...
