Botulinum Toxin and Electrophysiological Intervention Improve Post-Surgical Breast Entdoprosthetics: A Clinical Trial Study.

Introduction: The majority of plastic surgeon specialists note a distinct tendency to increase the number of breasts endoprosthetic surgeries with silicone implants in the Republic of Uzbekistan - the number of such surgeries now reaches 3-4 thousand annually. Breast replacement for aesthetic purposes is widespread throughout the world and has been rapidly spreading in Uzbekistan in recent years. Due to surgical endoprosthetics of mammary gland tissue with silicone implants, both in the early and late postoperative periods, quite often the patient's body experiences typical postoperative pain, which, if subclinical, requires constant dynamic monitoring and preventive rehabilitation procedures.

[Nitric Oxide(II) in the Biology of Chlorophyta].

NO is a gaseous signaling redox-active molecule that functions in various eukaryotes. However, its synthesis, turnover, and effects in cells are specific in plants in several aspects. Compared with higher plants, the role of NO in Chlorophyta has not been investigated enough.

[Acute disseminated encephalomyelitis and myelitis associated with new coronavirus infection COVID-19. Case report].

Acute disseminated encephalomyelitis (AEM) and acute transverse myelitis (OPM) are autoimmune demyelinating diseases of the central nervous system. Two clinical observations of AEM and OPM developed after suffering acute coronavirus infection (SARS-CoV-2) are presented. Differential diagnosis was carried out with multiple sclerosis, encephalitis of an infectious nature, compressive myelopathy, and opticomyelitis.

[Neuroinflammation in the pathogenesis of central neuropathic pain].

The problem of chronic pain is a significant question of nowadays medicine due to its high prevalence and treatment ineffectiveness in most cases. It has been proved by means of neuroimaging methods that chronic pain is always associated with glial activation in central nervous system, leading to the disturbance of glial cells participation in the eregulation of neuron microenvironment and neurotransmitter exchange. As a result, interneuronal communication in nociceptive pathways is interrupted and pathological neuroplasticity processes develop, causing the formation of pathological circuits, selfregilated by means of positive feedback.

Effects of arginine on Polytomella parva growth, PII protein levels and lipid body formation.

L-Arginine supports growth and resulted in increased PII signaling protein levels and lipid droplet accumulation in the colorless green alga Polytomella parva. Polytomella parva, a model system for nonphotosynthetic green algae, utilizes ammonium and several carbon sources, including ethanol and acetate. We previously reported that P.

[AUTOLOGOUS TRANSPLANTATION OF ADIPOSE TISSUE IN RECONSTRUCTIVE AND PLASTIC SURGERY. NEW POSSIBILITIES OF "OLD" MATERIAL].

The work is devoted to the methods of application of own adipose tissue as a plastic material and presents the summary of the currently known data on the use of transplantation of adipose tissue in order to correct various defects of the body in plastic and reconstructive surgery. There are analyzed theoretical basis for the use of adipose tissue, provided the methods of administration depending on the area of the use, the severity of the defect and its localization. Data on new methods of the use of adipose tissue and own observations are presented.

[PHOTODYNAMIC THERAPY FOR INTRADERMAL METASTASES OF BREAST CANCER USING THE MATRIX LIGHT-EMITTING DIODES APPARATUS LATUS].

There are presented results of photodynamic therapy (PDT) for patients with chemo- and radioresistant intradermal metastases of breast cancer using the matrix light-emitting diodes apparatus. To all patients prior to irradiation there was performed fluorescence diagnostics to assess the accumulation of the photosensitizer of chlorine series and photobleaching during PDT. The size of the irradiation area was 400 sm, the total dose of irradiation was 250J/cm2.

Regulation by light of ammonium transport systems in Chlamydomonas reinhardtii.

The unicellular green alga Chlamydomonas reinhardtii is able to take up methylammonium/ammonium from the medium at different stages of its sexual life cycle. Vegetative cells and pre-gametes mostly used a low-affinity system (LATS) component, but gametes obtained after light treatment of N-deprived pre-gametes expressed both LATS and high-affinity system (HATS) components for the uptake of methylammonium/ammonium. The activity of the LATS component was stimulated by light in only 5 min in a process independent of protein synthesis.

Chemotaxis to ammonium/methylammonium in Chlamydomonas reinhardtii: the role of transport systems for ammonium/methylammonium.

Ammonium is the preferred nitrogen source and chemoattractant for the unicellular green alga Chlamydomonas reinhardtii. Here we describe that chemotaxis to methylammonium, a non-metabolizable analogue to ammonium, that occurs only in vegetative cells and pregametes but not in gametes. A new methylammonium-resistant mutant, hat1 that was generated by insertional mutagenesis, has been isolated and found to be affected at multiple loci.

Phototropin plays a crucial role in controlling changes in chemotaxis during the initial phase of the sexual life cycle in Chlamydomonas.

During sexual differentiation, Chlamydomonas reinhardtii changes its chemotactic behavior in response to ammonium. Just like gamete formation, the change in chemotaxis mode is controlled by the sequential action of two environmental cues, removal of ammonium or nitrate from the medium and light. Thus, vegetative cells and mating incompetent pre-gametes, the latter being generated by nitrogen starvation in the dark, exhibit chemotaxis towards ammonium.

Chemotactic behavior of Chlamydomonas reinhardtii is altered during gametogenesis.

Chemotactic behavior of Chlamydomonas reinhardtii is altered during the sexual life cycle. Unlike vegetative cells and noncompetent pregametes, mature gametes did not show chemotaxis to ammonium. Loss of chemotaxis to ammonium in mating-competent cells is controlled by gamete-specific genes that are common for both mating-type gametes.

Isolation and characterisation of chemotactic mutants of Chlamydomonas reinhardtii obtained by insertional mutagenesis.

The swimming behaviour of the green flagellated protist Chlamydomonas reinhardtii is influenced by several different external stimuli including light and chemical attractants. Common components are involved in both the photo- and chemo-sensory transduction pathways, although the nature and organisation of these pathways are poorly understood. To learn more about the mechanism of chemotaxis in Chlamydomonas, we have generated nonchemotactic strains by insertional mutagenesis.

Isolation and Characterization of Chemotaxis Mutants of Chlamydomonas reinhardtii.

Zoospores of Chlamydomonas reinhardtii exhibit chemotaxis towards maltose, sucrose, xylose, mannitol, and ammonium. Ten independent mutants defective in chemotaxis towards sugars have been isolated. These mutants form five phenotypic classes.
