Determination of plasma properties in liquid jets through time-resolved experiments on third harmonic reflection dynamics.

The study of plasma in liquid jets represents a significant area of research encompassing plasma science, dynamics, and properties. This paper presents experimental studies on plasma formation processes in liquid jets of water, ethanol, and isopropyl based on the dynamics of the third harmonic (TH) reflection from the induced plasma. Through time-resolved experiments, and theoretical estimations using the Keldysh theory, plasma properties including density and frequency for all three media are evaluated.

Controlling water giant low-inertia nonlinear refractive index in the THz frequency range via temperature variation.

To create self-controlled radiation photonics systems, it is necessary to have complete information about the nonlinear properties of the materials used. In this Letter, the vibrational mechanism of the giant low-inertia cubic nonlinearity of the refractive index of water in the terahertz (THz) frequency range is experimentally proven. Its dominance, which manifests itself when the temperature of the liquid changes, is demonstrated.

Engineering the Optical Properties of CsPbBr Nanoplatelets through Cd Doping.

Lead halide perovskite nanoplatelets (NPls) attract significant attention due to their exceptional and tunable optical properties. Doping is a versatile strategy for modifying and improving the optical properties of colloidal nanostructures. However, the protocols for B-site doping have been rarely reported for 2D perovskite NPls.

Radiation shift from triple to quadruple frequency caused by the interaction of terahertz pulses with a nonlinear Kerr medium.

High-intensity optical radiation propagation in a transparent dielectric medium causes the phenomena of pulse self-action and radiation generation at triple frequencies due to the cubic nonlinearity of the medium. However, quadratic nonlinear effects usually outshine the cubic ones in anisotropic nonlinear crystals. In this work, we demonstrate that for certain experimental parameters the nonlinear effect of the third order can be stronger than the second order one in the MgO:[Formula: see text] crystal for terahertz frequency range.

Improved One- and Multiple-Photon Excited Photoluminescence from Cd-Doped CsPbBr Perovskite NCs.

Metal halide perovskite nanocrystals (NCs) attract much attention for light-emitting applications due to their exceptional optical properties. More recently, perovskite NCs have begun to be considered a promising material for nonlinear optical applications. Numerous strategies have recently been developed to improve the properties of metal halide perovskite NCs.

Speckle patterns formed by broadband terahertz radiation and their applications for ghost imaging.

Speckle patterns can be very promising for many applications due to their unique properties. This paper presents the possibility of numerically and experimentally formation of speckle patterns using broadband THz radiation. Strong dependence of the statistical parameters of speckles, such as size and sharpness on the parameters of the diffuser are demonstrated: the correlation length and the mean square deviation of the phase surface inhomogeneity.

Chiral carbon dots based on L/D-cysteine produced room temperature surface modification and one-pot carbonization.

Since chirality is one of the phenomena often occurring in nature, optically active chiral compounds are important for applications in the fields of biology, pharmacology, and medicine. With this in mind, chiral carbon dots (CDs), which are eco-friendly and easy-to-obtain light-emissive nanoparticles, offer great potential for sensing, bioimaging, enantioselective synthesis, and development of emitters of circularly polarized light. Herein, chiral CDs have been produced via two synthetic approaches using a chiral amino acid precursor l/d-cysteine: (i) surface modification treatment of achiral CDs at room temperature and (ii) one-pot carbonization in the presence of chiral precursor.

New technique of dissection of internal mammary vessels for breast reconstruction.

Background: Although internal mammary vessels are considered the best recipients for free flap breast reconstruction, they present the notable drawback of limited accessibility. The aim of this study was to develop a minimally invasive surgical technique for the dissection of internal mammary vessels as recipients for breast reconstruction.

Methods: From 2008 to 2018, we performed 32 unilateral microsurgical breast reconstructions (mean patient age: 40.

Lipid-mediated regulation of pore-forming activity of syringomycin E by thyroid hormones and xanthene dyes.

The effects of dipole modifiers, thyroid hormones (thyroxine and triiodothyronine) and xanthene dyes (Rose Bengal, phloxineB, erythrosin, eosinY and fluorescein) on the pore-forming activity of the lipopeptide syringomycin E (SRE) produced by Pseudomonas syringae were studied in a model bilayer. Thyroxine does not noticeably influence the steady-state number of open SRE channels (N), whereas triiodothyronine decreases it 10-fold at -50mV. Rose Bengal, phloxine B and erythrosin significantly increase N by 350, 100 and 70 times, respectively.

Small refinements in breast reconstruction: a technique for inframammary fold creation.

Background: In breast reconstructive surgery, the inframammary fold (IMF) is an essential component of breast identity. The lack of the IMF following previous mastectomy requires restoration. We have developed a new IMF reconstruction technique using the posterior sheet (PS) of the expander capsule.

Study on possibilities of reconstructive--plastic surgery in patients with stage III breast cancer.

Background: This population based study aimed to use reconstructive-plastic surgery with autologous tissue as a treatment of patients with stage III breast cancer.

Patients And Methods: We identified women (374) diagnosed with stage III breast cancer between 2000 and 2009 years. We compared radical operations with and without a plastic step, where 29 patients underwent the surgery in combination with an immediate radical resection with LD-flap replacement, mastectomy concurrently to TRAM-flap reconstruction in 103 patients.

[Primary plastic reconstructive surgery as a component of therapy for breast cancer].

We have carried out 281 primary plastic reconstructive operations (thoracodorsal flap--171; rectoabdominal flap--104) as a component of therapy for breast cancer in 1998-2004. Such indications as young age and the patient's desire to preserve the breast were considered. Radical intervention was followed by breast reconstruction.

[Parasternal lymph node excision in breast cancer].

Comparative analysis of the results of videothoracoscopic parasternal lymphadenectomy and standard mastectomy by Urban--Holdin is presented. In November 1995 to December 1999 205 videothoracoscopic parasternal lymphadenectomies were performed (96--on the left, 104--on the right). Central and medial location of breast cancer was indication for this operation.

The study was concerned with application of the stereotactic automated surgical biopsy breast with the ABBI (USSC) device for verification of non-palpable breast lumps. It included 13 females, aged 34-72 (mean age--54) and lasted 6 months (1999). Microcalcinates were detected in 3 (22.

[Biopsy of non-palpable tumors of the breast].

14 biopsies were performed in patients with non-palpable tumors of the breast with stereotaxic automated system (ABBI) and disposable "pistol-needle" ("Auto-Suture") whose needle-harpoon penetrates into pathologic focus under local anesthesia (four fold digital stereotaxic control guarantees the precision of biopsy). Non-palpable breast cancer in the tissue areas of 4, 7 and 11 mm in horizontal section was diagnosed in 3 patients. Biopsy was performed outpatiently, there were no complications.
