    Chronic cerebral ischemia is a common problem especially among the elderly. It gradually leads to social disability and invalidisationΒ of those patients. One of the possible pathogenic mechanisms of this condition is the endothelial dysfunction. Thus, the attempt to repairΒ the latter is one of the treatment goals. It is assumed that actovegin improves tissue microcirculation by expanding precapillary zone – the main marker of the metabolic activity in the microvascular endothelium. Actovegin activates anaerobic metabolism and oxygenationΒ in endotheliocytes. Patients, treated by actovegin, showed improvement of cognitive functions and psycho-emotional state. Due to the absenceΒ of proteins, the drug has good tolerance and low toxicity.Π₯роничСская ишСмия Π³ΠΎΠ»ΠΎΠ²Π½ΠΎΠ³ΠΎ ΠΌΠΎΠ·Π³Π° – распространСнная патология, особСнно срСди Π»ΠΈΡ† ΠΏΠΎΠΆΠΈΠ»ΠΎΠ³ΠΎ возраста, постСпСнно приводящая ΠΊ ΡΠΎΡ†ΠΈΠ°Π»ΡŒΠ½ΠΎΠΉ Π΄Π΅Π·Π°Π΄Π°ΠΏΡ‚Π°Ρ†ΠΈΠΈ ΠΈ ΠΈΠ½Π²Π°Π»ΠΈΠ΄ΠΈΠ·Π°Ρ†ΠΈΠΈ ΠΏΠ°Ρ†ΠΈΠ΅Π½Ρ‚ΠΎΠ².

    Today intravenous immunoglobulins are used increasingly in the management of patients with neurological conditions. The efficacy and safety of intravenous immunoglobulins treatment in chronic inflammatory demyelinating polyradiculoneuropathy, Guillain–Barre syndrome and multifocal motor neuropathy have been established in randomized controlled trials and declared in systematic reviews. There are discussions about the dose, timing, duration and necessity of repeated infusions in these disorders. The intravenous immunoglobulins treatment is an option in myasthenia gravis crisis and exacerbations the disease, stiff-person syndrome, a second-line therapy in dermatomyositis and some patients with polymyositis. The use of intravenous immunoglobulins in patients with multiple sclerosis, inclusion body myositis, resistant epilepsy is not finally proved. The review discussed the data of immunoglobulins efficacy in neurological disorders based on informative studies with an emphasis on the main criteria for choosing a drug for effective high-dose intravenous immunotherapy. БСгодня высокодозная тСрапия ΠΈΠΌΠΌΡƒΠ½ΠΎΠ³Π»ΠΎΠ±ΡƒΠ»ΠΈΠ½Π°ΠΌΠΈ Ρ‡Π΅Π»ΠΎΠ²Π΅ΠΊΠ° ΠΏΠΎΠ»ΡƒΡ‡Π°Π΅Ρ‚ всС большСС распространСниС Π² Π»Π΅Ρ‡Π΅Π½ΠΈΠΈ Π±ΠΎΠ»Π΅Π·Π½Π΅ΠΉ Π½Π΅Ρ€Π²Π½ΠΎΠΉ систСмы.

    The role of the ultrasound examination of the brachial plexus in thoracic outlet syndrome

    Get PDF
    Introduction. Difficulties in determining the compression of the neurovascular bundle with the thoracic outlet syndrome raises the question of finding an accessible and reproducible method for the neuroimaging of the brachial plexus and surrounding tissues.Purpose of the study – to develop an ultrasound diagnostic algorithm using a stress test to determine the level and cause of brachial plexus compression in comparison with the results of a clinical assessment.Materials and methods. 111 patients with verified compression of the brachial plexus at the level of the interstitial (65.7 %) and bone-clavicular space (21.6 %), as well as the tendon of the pectoralis minor muscle (12.6 %) were examined. The study protocol including the Adson ultrasound stress test, the assessment of the lower trunk in the interstitial space, and the test with ultrasound evaluation of the axillary artery at the level of the tendon of the pectoralis minor muscle with passive abduction of the arm back and up was used.Conclusion. An ultrasound study of the brachial plexus demonstrated informativeness in assessing the level and possible cause of compression, which opens up the possibility of using the method in routine neurological practice

    Photonic molecules and spectral engineering

    Full text link
    This chapter reviews the fundamental optical properties and applications of pho-tonic molecules (PMs) - photonic structures formed by electromagnetic coupling of two or more optical microcavities (photonic atoms). Controllable interaction between light and matter in photonic atoms can be further modified and en-hanced by the manipulation of their mutual coupling. Mechanical and optical tunability of PMs not only adds new functionalities to microcavity-based optical components but also paves the way for their use as testbeds for the exploration of novel physical regimes in atomic physics and quantum optics. Theoretical studies carried on for over a decade yielded novel PM designs that make possible lowering thresholds of semiconductor microlasers, producing directional light emission, achieving optically-induced transparency, and enhancing sensitivity of microcavity-based bio-, stress- and rotation-sensors. Recent advances in material science and nano-fabrication techniques make possible the realization of optimally-tuned PMs for cavity quantum electrodynamic experiments, classical and quantum information processing, and sensing.Comment: A review book chapter: 29 pages, 19 figure

    Sustainable polyethylene fabrics with engineered moisture transport for passive cooling

    Get PDF
    Polyethylene (PE) has emerged recently as a promising polymer for incorporation in wearable textiles owing to its high infrared transparency and tuneable visible opacity, which allows the human body to cool via thermal radiation, potentially saving energy on building refrigeration. Here, we show that single-material PE fabrics may offer a sustainable, high-performance alternative to conventional textiles, extending beyond radiative cooling. PE fabrics exhibit ultra-light weight, low material cost and recyclability. Industrial materials sustainability (Higg) index calculations predict a low environmental footprint for PE fabrics in the production phase. We engineered PE fibres, yarns and fabrics to achieve efficient water wicking and fast-drying performance which, combined with their excellent stain resistance, offer promise in reducing energy and water consumption as well as the environmental footprint of PE textiles in their use phase. Unlike previously explored nanoporous PE materials, the high-performance PE fabrics in this study are made from fibres melt spun and woven on standard equipment used by the textile industry worldwide and do not require any chemical coatings. We further demonstrate that these PE fibres can be dry coloured during fabrication, resulting in dramatic water savings without masking the PE molecular fingerprints scanned during the automated recycling process

Here the authors show that polyethylene is a sustainable alternative textile with water wicking and fast-drying performance. The fabrication of polyethylene fabrics is compatible with standard equipment and could be dry-coloured, further reducing water consumption

    We report a 40-year-old woman presented with consciousness disturbance, ataxia, asymmetrical limb weakness, hyperreflexia. Due to magnetic resonance imaging findings, the patient was diagnosed with Bickerstaff’s brainstem encephalitis overlapped with acute transverse myelitis. Later she developed distal muscles atrophy and the electroneuromyographic study revealed axonal motor neuropathy, therefore acute motor axonal neuropathy was diagnosed. The patient underwent one course of intravenous immunoglobulin therapy with the regression of symptoms and magnetic resonance imaging changes. Nine months after symptoms onset, the patient has completely recovered. This overlapping case of Bickerstaff’s brainstem encephalitis, acute transverse myelitis and acute motor axonal neuropathy provides further support that these conditions are part of the same spectrum.Β ΠŸΡ€Π΅Π΄ΡΡ‚Π°Π²Π»Π΅Π½ΠΎ клиничСскоС наблюдСниС ΠΏΠ°Ρ†ΠΈΠ΅Π½Ρ‚ΠΊΠΈ 40 Π»Π΅Ρ‚ с Π½Π°Ρ€ΡƒΡˆΠ΅Π½ΠΈΠ΅ΠΌ сознания, атаксиСй, асиммСтричным Π½ΠΈΠΆΠ½ΠΈΠΌ ΠΏΠ°Ρ€Π°ΠΏΠ°- Ρ€Π΅Π·ΠΎΠΌ, гипСррСфлСксиСй.

    Detecting and identifying single molecules are the ultimate goal of analytic sensitivity. Single molecule detection by surface-enhanced Raman scattering (SM-SERS) depends predominantly on SERS-active metal substrates that are usually colloidal silver fractal clusters. However, the high chemical reactivity of silver and the low reproducibility of its complicated synthesis with fractal clusters have been serious obstacles to practical applications of SERS, particularly for probing single biomolecules in extensive physiological environments. Here we report a large-scale, free standing and chemically stable SERS substrate for both resonant and nonresonant single molecule detection. Our robust substrate is made from wrinkled nanoporous Au79Ag21 films that contain a high number of electromagnetic β€œhot spots” with a local SERS enhancement larger than 109. This biocompatible gold-based SERS substrate with superior reproducibility, excellent chemical stability and facile synthesis promises to be an ideal candidate for a wide range of applications in life science and environment protection
