    The presence of an autoimmune cellular mechanism for destroying erythrocytes on the basis of results of experiments in vivo is demonstrated in the blood and the organs. This mechanism is made up of a population of immunocompetent killer-lymphocytes which originates in the bone marrow and the thymus, and which is manifested in the local hemolysis effect

    Grasshoppers (Orthoptera: Acridoidea) of the North-West Caucasus: fauna, ecology, landscape and biotopic distribution

    Get PDF
    Sixty one species of grasshoppers from 35  genera and 8  subfamilies are recorded for the North-West Caucasus. The features of biotopic distribution of grasshoppers are analyzed on the main types of landscapes in the region. In the Kuban  – CisAzov biogeographic province, the highest diversity of grasshoppers is characteristic of steppe biotopes with forb-grass vegetation, where 25  species are noted. The highest diversity is typical for low-mountain meadows and mountain steppes, which number 22 grasshoppers species each in the Black  Sea  – Kuban province. At the same time, these landscapes are characterized by a low value of the measure of similarity of Sørensen-Chekanovsky (0.51). Gramineous chortobionts (52%) and facultative chortobionts (16%) dominate in the fauna of the NorthWest Caucasus, the remaining life forms of grasshoppers are represented by a relatively small number of species. Among the grasshoppers, seven endemic species for the North-West Caucasus, as well as two endemic species for the whole Caucasus, are noted

    Photodynamic Opening of the Blood–Brain Barrier and the Meningeal Lymphatic System: The New Niche in Immunotherapy for Brain Tumors

    Get PDF
    Photodynamic therapy (PDT) is a promising add-on therapy to the current standard of care for patients with glioblastoma (GBM). The traditional explanation of the anti-cancer PDT effects involves the PDT-induced generation of a singlet oxygen in the GBM cells, which causes tumor cell death and microvasculature collapse. Recently, new vascular mechanisms of PDT associated with opening of the blood–brain barrier (OBBB) and the activation of functions of the meningeal lymphatic vessels have been discovered. In this review, we highlight the emerging trends and future promises of immunotherapy for brain tumors and discuss PDT-OBBB as a new niche and an important informative platform for the development of innovative pharmacological strategies for the modulation of brain tumor immunity and the improvement of immunotherapy for GBM.RF Governmental GrantRSFRFBRPeer Reviewe

    Experimental research on plasma destruction of bone tissue

    The main condition in achieving a favorable outcome is surgical treatment of patients with tumor-like diseases and benign bone tumors erosion of neoplasm within the healthy tissues. To reduce the number of recurrences the various chemical and physical methods on resection areas have been performed. The authors have proposed a new method of low temperature plasma treatment of bone tissue with the temperature of 20000°C. Exposing the plasma flow on bone tissue leads to loss of all cellular elements including neoplastic elements with preservation of the mineral bone structure. The direct correlation between the capacity of the plasma flow and intensity of bone destruction has been defined. This allows a differentiated use of plasma destruction in skeletal bones according to anatomy, size and type of bone tissue (spongy or cortical) as well as patient's individual condition of the tissu

    Phototherapy of Alzheimer’s Disease: Photostimulation of Brain Lymphatics during Sleep: A Systematic Review

    Get PDF
    The global number of people with Alzheimer’s disease (AD) doubles every 5 years. It has been established that unless an effective treatment for AD is found, the incidence of AD will triple by 2060. However, pharmacological therapies for AD have failed to show effectiveness and safety. Therefore, the search for alternative methods for treating AD is an urgent problem in medicine. The lymphatic drainage and removal system of the brain (LDRSB) plays an important role in resistance to the progression of AD. The development of methods for augmentation of the LDRSB functions may contribute to progress in AD therapy. Photobiomodulation (PBM) is considered to be a non-pharmacological and safe approach for AD therapy. Here, we highlight the most recent and relevant studies of PBM for AD. We focus on emerging evidence that indicates the potential benefits of PBM during sleep for modulation of natural activation of the LDRSB at nighttime, providing effective removal of metabolites, including amyloid-β, from the brain, leading to reduced progression of AD. Our review creates a new niche in the therapy of brain diseases during sleep and sheds light on the development of smart sleep technologies for neurodegenerative diseases.RSFRF GovernmentalAcademic leadership program Priority 2030 proposed by the First Moscow State Medical University of the Ministry of Health of the Russian Federation (Sechenov University)Peer Reviewe

    Brain Waste Removal System and Sleep: Photobiomodulation as an Innovative Strategy for Night Therapy of Brain Diseases

    Get PDF
    Emerging evidence suggests that an important function of the sleeping brain is the removal of wastes and toxins from the central nervous system (CNS) due to the activation of the brain waste removal system (BWRS). The meningeal lymphatic vessels (MLVs) are an important part of the BWRS. A decrease in MLV function is associated with Alzheimer’s and Parkinson’s diseases, intracranial hemorrhages, brain tumors and trauma. Since the BWRS is activated during sleep, a new idea is now being actively discussed in the scientific community: night stimulation of the BWRS might be an innovative and promising strategy for neurorehabilitation medicine. This review highlights new trends in photobiomodulation of the BWRS/MLVs during deep sleep as a breakthrough technology for the effective removal of wastes and unnecessary compounds from the brain in order to increase the neuroprotection of the CNS as well as to prevent or delay various brain diseases.RF GovernmentalRSFRFBRInnovation Fund of WNLO and Innovation Project of Optics Valley LaboratoryNational Natural Science Foundation of China (NSFC)Peer Reviewe

    Photobiomodulation of lymphatic drainage and clearance: perspective strategy for augmentation of meningeal lymphatic functions

    Get PDF
    There is a hypothesis that augmentation of the drainage and clearing function of the meningeal lymphatic vessels (MLVs) might be a promising therapeutic target for preventing neurological diseases. Here we investigate mechanisms of photobiomodulation (PBM, 1267 nm) of lymphatic drainage and clearance. Our results obtained at optical coherence tomography (OCT) give strong evidence that low PBM doses (5 and 10 J/cm2) stimulate drainage function of the lymphatic vessels via vasodilation (OCT data on the mesenteric lymphatics) and stimulation of lymphatic clearance (OCT data on clearance of gold nanorods from the brain) that was supported by confocal imaging of clearance of FITC-dextran from the cortex via MLVs. We assume that PBM-mediated relaxation of the lymphatic vessels can be possible mechanisms underlying increasing the permeability of the lymphatic endothelium that allows molecules transported by the lymphatic vessels and explain PBM stimulation of lymphatic drainage and clearance. These findings open new strategies for the stimulation of MLVs functions and non-pharmacological therapy of brain diseases
