Fractional carbon dioxide vaginal laser treatment of stress urinary incontinence: Remodeling of vaginal tissues and improving pelvic floor structures.

Objective: To demonstrate remodeling of vaginal biomechanical and physiological properties using vaginal fractional carbon dioxide (CO ) laser treatment of stress urinary incontinence (SUI).

Materials And Methods: The study cohort included 26 patients with SUI between October 2019 and November 2020. Patients were treated with two sessions of FemTouch vaginal fractional CO laser with a one-month interval.

Fractional Carbon Dioxide Laser Improves Vaginal Laxity via Remodeling of Vaginal Tissues in Asian Women.

Background: Vaginal laxity (VL) is characterized by the relaxing of the vaginal wall that affects the quality of life and sexual function of patients. The current management of VL such as Kegel exercises and topical or systemic hormonal replacement results in unsatisfactory outcomes; thus, novel modalities are needed to improve the efficacy. Vaginal fractional carbon dioxide (CO2) laser treatment has shown growing applications for the treatment of VL, but results show nonconformities due to the lack of objective evaluations.

Treatment of acne vulgaris using 1,565 nm non-ablative fractional laser in combination with isotretinoin and pricking blood therapy.

Objective: We aimed to evaluate the efficacy and safety of the 1,565 nm non-ablative fractional laser (NAFL) in combination with isotretinoin and pricking blood therapy (PBT) for treatment of AV.

Methods: A retrospective analysis of 60 patients with moderate-to-severe AV was performed. Four groups ( = 15) were evaluated: 1,565nm NAFL alone, oral isotretinoin alone, double therapy (NAFL + isotretinoin) and triple therapy (NAFL + isotretinoin + PBT).

Semi-Quantitatively Designing Two-Photon High-Performance Fluorescent Probes for Glutathione S-Transferases.

Glutathione S-transferases (GSTs), detoxification enzymes that catalyze the addition of glutathione (GSH) to diverse electrophilic molecules, are often overexpressed in various tumor cells. While fluorescent probes for GSTs have often adopted the 2,4-dinitrobenzenesulfonyl (DNs) group as the receptor unit, they usually suffer from considerable background reaction noise with GSH due to excessive electron deficiency. However, weakening this reactivity is generally accompanied by loss of sensitivity for GSTs, and therefore, finely turning down the reactivity while maintaining certain sensitivity is critical for developing a practical probe.

Clinical Efficacy and Safety of 3DEEP Multisource Radiofrequency Therapy Combined with Fractional Skin Resurfacing for Periocular Skin Aging.

The early signs of skin aging usually occur in the periocular region. This retrospective analysis evaluated the efficacy and safety profile of a multisource 3DEEP radiofrequency (RF) technology (EndyMed, Caesarea, Israel) in combination with fractional skin resurfacing (FSR) for the treatment of periocular skin aging. A total of 15 patients with periocular aging underwent monthly treatment sessions of 3DEEP and FSR for three months.

Thermochemistry and Initial Decomposition Pathways of Triazole Energetic Materials.

A thorough investigation of the initial decomposition pathways of triazoles and their nitro-substituted derivatives has been conducted using the MP2 method for optimization and DLPNO-CCSD(T) method for energy. Different initial thermolysis mechanisms are proposed for 1,2,4-triazole and 1,2,3-triazole, the two kinds of triazoles. The higher energy barrier of the primary decomposition path of 1,2,4-triazole (H-transfer path, ∼52 kcal/mol) compared with that of 1,2,3-triazole (ring-open path, ∼45 kcal/mol) shows that 1,2,4-triazole is more stable, consistent with experimental observations.

New insights into the sensing mechanism of a phosphonate pyrene chemosensor for TNT.

As security needs have increased, mechanism investigation has become of high importance in the development of new sensitive and selective chemosensors for chemical explosives. This study details a theoretical investigation of the sensing mechanism of a new phosphonate pyrene chemosensor for trinitrotoluene (TNT), suggesting a different interaction mode between the probe and TNT from the one previously reported. The invalidity of the mechanism of binding TNT through intermolecular hydrogen bonds was proved using the Gibbs free energy profile and 1H NMR analysis.

Reconsideration of the Detection and Fluorescence Mechanism of a Pyrene-Based Chemosensor for TNT.

The rapid detection of chemical explosives is crucial for national security and public safety, and the investigation of sensing mechanisms is important for designing highly efficient chemosensors. This study theoretically investigates the detection and fluorescence mechanism of a newly synthesized pyrene-based chemosensor for the detection of trinitrotoluene (TNT) through density-functional-theory (DFT) and time-dependent density-functional-theory (TDDFT) methods and suggests a different interaction product of the probe and TNT from previously reported ones [ Mosca et al.
