    Intracellular and extracellular accumulation of fibrillary proteins, beta-amyloid and hyperphosphorylated Tau, in patients with Alzheimer’s disease (AD) leads to chronic and progressive neurodegenerative process. Overaccumulation of aggregates results in synaptic dysfunction and inevitable neuronal loss. Although the exact molecular pathways of the AD still require better understanding, it is clear this neuropathology is a multifactorial disorder where the advanced age is the main risk factor. Lately, several dozens of drug candidates have succeeded to phase II clinical trials; however, none has passed phase III. In this review we summarize existing data on anti-AD therapeutic agents currently undergoing clinical trials and included in the public websites www.clinicaltrials.gov and Alzforum.org as well as the Thomson Reuters Β«IntegrityΒ» database. We revealed three major trends in AD drug discovery. First, developing of β€œdisease-modifying agents” could potentially slow the progression of structural and functional abnormalities in the central nervous system providing sustainable improvements of cognitive functions, which persist even after drug withdrawal. Secondly, the focused design of multitargeted drugs acting on multiple key molecular pathways. Finally, the repositioning of drugs that are already available on the market for the novel (anti-AD) application provides a promising strategy for finishing clinical trials and re-marketing.ΠŸΡ€ΠΈ Π±ΠΎΠ»Π΅Π·Π½ΠΈ ΠΠ»ΡŒΡ†Π³Π΅ΠΉΠΌΠ΅Ρ€Π° (БА) происходит Π²Π½ΡƒΡ‚Ρ€ΠΈΠΊΠ»Π΅Ρ‚ΠΎΡ‡Π½ΠΎΠ΅ ΠΈ Π²Π½Π΅ΠΊΠ»Π΅Ρ‚ΠΎΡ‡Π½ΠΎΠ΅ Π½Π°ΠΊΠΎΠΏΠ»Π΅Π½ΠΈΠ΅ фибриллярных Π±Π΅Π»ΠΊΠΎΠ²: Π±Π΅Ρ‚Π°-Π°ΠΌΠΈΠ»ΠΎΠΈΠ΄Π° ΠΈ гипСрфосфорилированного Ρ‚Π°Ρƒ, ΠΊΠΎΡ‚ΠΎΡ€Ρ‹Π΅ приводят ΠΊ хроничСскому ΠΈ ΠΏΡ€ΠΎΠ³Ρ€Π΅ΡΡΠΈΡ€ΡƒΡŽΡ‰Π΅ΠΌΡƒ Π½Π΅ΠΉΡ€ΠΎΠ΄Π΅Π³Π΅Π½Π΅Ρ€Π°Ρ‚ΠΈΠ²Π½ΠΎΠΌΡƒ процСссу Π² ΠΌΠΎΠ·Π³Π΅.

    This review contains information about different laboratorian rodentβ€²s gait analysis systems. These methods are useful for the assessment of motor function in neurodegenerative models. The following aspects have been considered: ink traces technique, treadmills equipment, and modern gait analysis systems like TreadScan and CatWalk, which allows estimating a set of animals gait parameters. For each technique a detailed description and examples of its use for estimating gait parameters in neurodegenerative diseases are given.Π’ Π΄Π°Π½Π½ΠΎΠΉ ΡΡ‚Π°Ρ‚ΡŒΠ΅ Ρ€Π΅Ρ‡ΡŒ ΠΏΠΎΠΉΠ΄Ρ‘Ρ‚ ΠΎ Ρ€Π°Π·Π»ΠΈΡ‡Π½Ρ‹Ρ… ΠΌΠ΅Ρ‚ΠΎΠ΄ΠΈΠΊΠ°Ρ… ΠΎΡ†Π΅Π½ΠΊΠΈ ΠΏΠΎΡ…ΠΎΠ΄ΠΊΠΈ Π»Π°Π±ΠΎΡ€Π°Ρ‚ΠΎΡ€Π½Ρ‹Ρ… Π³Ρ€Ρ‹Π·ΡƒΠ½ΠΎΠ².

    Gamma-carbolines derivatives as promising agents for the development of pathogenic therapy for proteinopathy

    Get PDF
    Uncontrolled protein aggregation, accompanied by the formation of specific inclusions, is a major component of the pathogenesis of many common neurodegenerative diseases known as proteinopathies. The intermediate products of this aggregation are toxic to neurons and may be lethal. The development strategy of pathogenic therapy for proteinopathy is based on the design of drugs capable of both inhibiting proteinopathy progression and increasing the survival of affected neurons. The results of a decade-long research effort at leading Russian and international laboratories have demonstrated that Dimebon (Latrepirdine), as well as a number of its derivatives from a gamma-carboline group, show a strong neuroprotective effect and can modulate the course of a neurodegenerative process in both in vitro and in vivo model systems. The accumulated data indicate that gamma-carbolines are promising compounds for the development of pathogenic therapy for proteinopathies

    The study is devoted to the development of an artificial material based on the ultrahigh-molecular weight polyethylene (UHMWPE) with a porous or cellular 3D structure as a cellular matrix – a framework for growing cell cultures. The development of such matrix provides support for neuronal cell culture under conditions that mimick those that exist in the living body. Typically, in vitro cellular studies are conducted in a 2D format, which limits intercellular interactions, morphology, differentiation, survival, signaling responses, gene expression and proliferation that are found in vivo. Here, we propose to use UHMWPE as a material of the cellular matrix, the ultra-high molecular weight polyethylene. UHMWP is a bioinert substance, wich allows forming a system of open connected pores needed to provide cellular life conditions with supply of nutrients and oxygen as well as the removal of waste products, the possibility of intercellular communication, etc. As a result, the use of UHMWPE as a cellular matrix will allow to study the processes occurring in cells in the 3D environment.Π Π°Π±ΠΎΡ‚Π° посвящСна Π°Π½Π°Π»ΠΈΠ·Ρƒ свойств искусствСнного ΠΌΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Π° Π½Π° основС свСрхвысокомолСкулярного полиэтилСна (Π‘Π’ΠœΠŸΠ­) с пористой ΠΈΠ»ΠΈ ячСистой 3D-структурой, ΠΊΠΎΡ‚ΠΎΡ€Ρ‹ΠΉ ΠΈΡΠΏΠΎΠ»ΡŒΠ·ΡƒΠ΅Ρ‚ΡΡ Π² качСствС ΠΊΠ»Π΅Ρ‚ΠΎΡ‡Π½ΠΎΠ³ΠΎ матрикса – каркаса для выращивания ΠΊΡƒΠ»ΡŒΡ‚ΡƒΡ€Ρ‹ ΠΊΠ»Π΅Ρ‚ΠΎΠΊ.

    Justification and calculation of design features of drum-type hydroponics

    No full text
    The purpose of the article is to evaluate the design features of rotary hydroponics and then obtain a method for calculating the main technical characteristics. Drum (rotary) hydroponics is a promising method of growing on artificial media. The planting surface in this method is located on the inner cylindrical surface of the rotor rotating around the lamp. The design of the rotary hydroponics has a number of advantages such as: smaller installation area due to planting in the cylinder area; energy savings due to rational use of the light source; liquid saving for the formation of a nutrient solution due to the alternate immersion of the roots in a more compact bath. In this paper, a number of theoretical aspects for the calculation of drum (rotary) hydroponic machines is considered to ensure the highest productivity. As a result, a method for calculating the following characteristics was derived: determination of the required radius of the rotor depending on plant height; number of planting spots with a known radius and width of the rotor; minimum amount of necessary nutrient solution; electricity consumed when using LED lamps
