Whit ham method of the expansion near the wave front propagating on the river with bed load transport
Authors: Hung Pham
Published: April 2018

In this paper the non linear differential equation describing the behavior of water surface behind the wave front is obtained by Whit ham method. It is shown that the bed load transport could influence significantly on the stability of the flood wave. In the supercritical flow, the bed load wave will propagate upstream and will linearly stabilize. The different situations when the wave could topple over are analyzed. In the flow without the bed load transport, the results of Whit ham have been reobtained as a special case.

We suggest a general approach based on the nearest-neighbor tight-binding approximation (TB) to investigate the band structure and conductance of a quasi-one dimensional system. Numerical calculations carried out for Graphene nanoribbons (GNRs) with different widths and edge conditions (zigzag and armchair) reveal the well-known results that the electronic properties of GNRs depend strongly on the size and geometry of the sample.
A study on morphogenesis of roots of Panax stipuleanatus H.T.Tsai et K.M.Feng in vitro and preliminary determination of oleanolic acid in roots
Authors: Hương Nguyễn Thị Ngọc , Hùng Trần , Đẹp Trương Thị
Published: April 2018

Panax stipuleanatus H.T.Tsai et K.M.Feng which belongs to the genus Panax (Araliaceae family) is an valuable medicinal herbs in Vietnam and China. In the rhizome of Panax stipuleanatus H.T.Tsai et K.M.Feng contains many olean-type triterpenoid saponins, which can improve mental stamina and reduces risks of cancers in humans. Up to now, there is no research on the morphological changes in adventitious root formation from the rhizome of this species. In this study, the callus morphogenesis from the rhizome and the adventitious root morphogenesis from callus were analyzed. The rhizome segments 1-1.5 cm in diameter and 1 cm thick were cultured on MS medium supplemented 30 g/l sucrose, 6 g/l agar and 0.5 mg/l 2.4-D in dark. Callus formed on the surface of the rhizome after four weeks. The first cell divisions occurred in the first two weeks, in secondary cortex parenchyma cells and vascular cambium of the rhizome. 26-week-old callus with slow cell proliferation within the cluster and the long cells outside clusters were transferred to the induced medium supplemented with 0.5 mg/l 2.4-D and 0.1 mg/l TDZ within 6 weeks. The calli were more tight and formed many clusters. The adventitious roots formed 10 weeks after the transfer to MS medium supplemented with 0.5 mg/l NAA. Callus formed spherical structures called embryo-liked but only developed the root pole. Results of the thin layer chromatography using chloroform–methanol (9:1, v/v) showed the presence of oleanolic acid in extracts of adventitious roots fromed from callus-derived rhizomes of Panax stipuleanatus H.T.Tsai et K.M.Feng.

No report on plant regeneration via somatic embryogenesis of P. vietnamensis has been previously published. In the present study, somatic embryogenesis via callus formation from cultures of leaf transverse thin cell layers (tTCLs) of Vietnamese ginseng (Panax vietnamensis Ha et Grushv.) was investigated. α-naphthaleneacetic acid (NAA), 2,4-dichlorophenoxyacetic acid (2,4-D), 6-benzylaminopurine (BA) and thidiazuron (TDZ) were added separately and in combination into the culture media. Explant necrosis or low callogenesis rates were observed when 1-mm wide leaf tTCLs were cultured on media with TDZ, BA, 2,4-D or NAA. On the other hand, calli were successfully induced from the tTCL explants cultured on medium supplemented with either 2,4-D and BA or 2,4-D and TDZ. Callogenesis was observed under both light and dark conditions. The highest callogenesis rate (100%) was obtained on Murashige and Skoog (MS) basal medium supplemented with 1.0 mg l-1 2,4-D in combination with 0.1 mg l-1 TDZ in darkness after eight weeks of culture. White calli were cut into small pieces (1.0 x 1.0 cm dimension) and placed on MS media containing 1.0 mg l-1 2,4-D, 0.5 mg l-1 NAA and TDZ at various concentrations (0.01; 0.1; 0.2; and 0.5 mg l-1), and the best callus proliferation was recorded on medium containing 1.0 mg l-1 2,4-D and 0.2 mg l-1 TDZ. Somatic embryogenesis, with a success rate of 53.3% and 35 embryos per explant, was achieved when calli were subcultured onto MS medium supplemented with 1.0 mg l-1 2,4-D, 0.5 mg l-1 NAA and 0.2 mg l-1 TDZ.

Published: April 2018

In this study, adventitious and hairy roots of Vietnamese ginseng were used to assess the ability of growth and saponin accumulation. Adventitious roots were derived from leaf samples in vitro (1.0 x 1.0 cm of size) cultured on SH medium supplemented with 5.0 mg.l-1 IBA, 30 g.l-1 sucrose, 8 g.l-1 agar, pH 5.8, and subcultured on the same medium for multiplication. Hairy roots were derived from callus infected with Agrobacterium rhizogenes strain ATCC 15834, then these roots were cultured on plant growth regulators-free SH medium supplemented with 50 g.l-1 sucrose, 8 g.l-1 agar, pH 5.8. During the early culture of two months, the results showed that the growth rate of hairy roots was lower than that of adventitious roots. However, in the later period of culture, the growth rate of hairy roots was higher than that of adventitious roots. After 5 months of culture, the growth rate of hairy roots was 20.87 times and they kept growing as well as branching, while the growth rate of adventitious roots was only 13.52 times and they did not grow further after three months of culture. Analytical results showed that the total saponins of total dry matter of hairy roots (0.101 mg) were higher than that of adventitious roots (0.0681 mg). The main ginsenoside of hairy roots (MR2) was also higher than that of adventitious roots 3.03 fold. In addition, the hairy roots grew on plant growth regulators-free medium while adventitious roots grew on medium supplemented with auxin. Therefore, hairy roots proved to be suitable source material for Vietnamese ginseng root biomass production in the bioreactor systems.

Published: April 2018

Acanthus ilicifolius is a common medicinal herb used in treatment for hepatic diseases in Vietnamese traditional medicine. This study investigated hepatoprotective effects of methanol extract of A.ilicifolius roots at various concentrations on mice having carbon tetrachloride (CCl4)-induced liver damages by measuring levels of two liver enzymes (alanine aminotransferase (ALT) and aspartate aminotransferase (AST)). Mice’s livers were injured by using CCl4 in olive oil, in the ratio of 1 to 4 with the dosing concentration of 0.2 ml per day in 4 consecutive weeks (or 8 consecutive weeks). After one hour taking CCl4 by oral administration, mice were treated with roots’ methanol extract at three different concentrations (15, 30, and 45 mg/kg BW). Silymarin, a commercial liver protector was used as a positive control. After 4 weeks of treatment, the AST levels decreased by 86.6%, 86.3%, 85.3% and ALT levels declined by 83.9%, 83.8%, 81.4%. After 8 weeks of treatment, the use of 30 mg/kg BW root extract showed the best hepatoprotective activity with the lowest levels of AST and ALT. Our result also indicated that the hepatoprotective effects of roots’ methanol extract of A.ilicifolius were similar to that of sylimarin (using at 16 mg/kg BW). The microscopic structure proved that the hepatocytes recovered significantly in mice treated with roots’ methanol extract of A.ilicifolius at dose 45 mg/kg BW. However, root extract of A.ilicifolius at dose of 15 and 30 mg/kg BW could not improved liver damages comparing to untreated mice. The qualitative analysis of phytochemical compounds showed that Acanthus ilicifolius root contains alkaloid, flavonoid, triterpenoid, steroid, glycoside, and phenol substances.
Elimination of iron from acidic mine drainage (AMD) in the co-treatment with poultry wastewater through a sulfate-reducing bioreactor
Authors: Hải Nguyễn Thị , Hằng Đinh Thuý
Published: April 2018

Acid mine drainage (AMD) is contaminated water from mining indistry, characterized by low pH (1 – 4) and high concentration of heavy metals (up to thousands ppm). AMD is highly toxic to aquatic life and soil ecology surrounding the mining areas, therefore should be treated adequately before discharging to the environment. The treatment technology based on sulfate-reducing bioreactors has been applying widely with high efficiency. Sulfate-reducing bacteria (SRB) stand at the central point of the technology, use hydrogen and organic carbons to reduce sulfate to sulfde, that involve in metal precipitation and pH neutralization. For establishing the technology, sources of SRB as well as organic substrates neccesary for the bacteria should be acquired from outside. In many cases, these two requirements can be supplied from cow manure and agriculture residues (such as rice straws) added to the bioreactor before operating. In the present study, a mixed culture of SRB enriched from aquaculture-processing wastewater was used to start up the sulfate-reducing bioreactor for the AMD-treatment laboratory model. Cotreatment of AMD and poultry wastewater in this model operated under continuous mode with retention time of 48 h allowed to remove 85 – 88% Fe2+ in the AMD (from the original concentration of 200 mg/L). Study of the bacterial community via DGGE analyses of the 16S rDNA fragments showed that the enrichment culture consisted of three main SRB genera Desulfovibrio, Desulfomicrobium and Desulfobulbus spp., whereas in the sediment of the bioreactor only Desulfovibrio spp were found dominating. The obtained results would serve as basis for the development of biological-based technology to treat AMD together with organic-rich wastewater sources, suitable for mines located closely to residential areas.

Microorganisms are especially interested in due to the ability to produce secondary compounds with high-value applications. Plenty of novel and diverse chemical structures have been found in the bioactive substances of microorganisms. In this study, we isolated 143 strains of bacteria and actinomycetes from 161 samples including: sediments, sponges, soft corals, echinoderms and starfish collected from three sea areas of Viet Nam: Ha Long - Cat Ba; Co To - ThanhLan; Bai Tu Long. The strains were fermented in A1 medium and then fermentation broths were extracted 5 times with ethyl acetate. The extraction residue screening test using 7 reference strains isolated 15 target strains with the highest biological activity. Most of these strains have dramatic inhibition on Gram positive bacteria: Enterococcus faecalis ATCC29212; Bacillus cereus ATCC13245  and Candida albicans ATCC10231 with MIC values  ​​less than or equal to the MIC value of the reference antibiotic. In particular, strain G057 was active against S. enterica ATCC 13076 and G002 inhibited E. coli ATCC25922 with respective values  ​​MICG057 = 8 µg/ ml, MICG002 = 256µg/ ml; and three strains G115, G119, G120 showed the inhibitory effect towards P. aeruginosa ATCC27853 with respective values ​​MICG115 = 64 µg/ ml, MICG119 = 32 µg/ ml and MICG120 = 32 µg/ ml. All 15 strains were then subjected to morphological and phylogenetic investigations based on 16S rRNA gene sequences. The results showed that 9 of 15 strains G016, G017, G019, G043, G044, G047, G068, G119 and G120 belonged to Genus Micromonospora; strains G039 and G065 were identified as Genus Stretomyces; G002 was  identified as Bacillus; G057 was  identified as Nocardiopsis; G115 was in Photobacterium and G121 belonged Oceanisphaera.

Published: April 2018

With Glucose-6-phosphate dehydrogenase (G6PD) deficiency being the most common enzyme disorder in human, there have been 184 discovered point mutations and several methods that have been applied for diagnosing this disease. However, these techniques often pose several major problems such as being time-consuming, low sensitivity and high cost. Recently, the High Resolution Melting (HRM) has been studied and proven to be effective for DNA genotyping, mutation scanning and sequence matching. Therefore, HRM has been chosen for diagnosing G6PD deficiency via Viangchan mutation in this study. In this study, a total of 56 dried blood spot samples (including six control samples which were known the exact genotype by sequencing and fifty unknown samples) were collected and extracted DNA by using QIAamp DNA Blood Mini Kit. Primers for HRM analysis were designed through by the Umelt software. Then HRM optimization was carried out for annealing temperature of primers (Ta) and MgCl2 concentration on six control samples. The optimized HRM protocol with 2.5 μM of MgCl2 and Ta at 62oC was applied for fifty G6PD samples and then comparing with ARMS-PCR genotyping results for the validation process. In the final step, genotyping results were confirmed by sequencing. In a results, both sensitivity and specificity of this technique reached 100%. Based on these favorable outcomes, this study has successfully optimized the HRM conditions for diagnosing fifty G6PD samples. It was such an essential precondition that showed HRM could be applied for other types of G6PD through other types of mutations such as Canton mutation or continues to be developed for HRM-Multiplex reactions.
Antibacterial activity of three wild wood-decaying fungi in southern Vietnam toward Vibrio parahaemolyticus bacterium in aquaculture wastewater
Authors: Vu Ngo Nguyen , Ngoc Pham Van Kim , Hoa Pham Thi
Published: April 2018

This research demonstrated antibacterial activity of wood-decaying fungi to treat the aquaculture pathogenic bacterium, Vibrio parahaemolyticus (V. parahaemolyticus). Three wild wood-decaying fungi (WDF) collected in Southern Vietnam including Flavodon flavus (F. flavus), Physisporinus vitreis (P. vitreis), and Schizophyllum commune (S. commune) were tested to treat V. parahaemolyticus presented in aquaculture wastewater. Fungal adaptation to different salt concentrations at 0, 10, 15, 20, and 30‰ was tested for the assessment of application potential of these fungi in the aquaculture farming. Fungal mycelium could adapt differently to saline conditions. All three strains grew well at low salt concentration (0-10‰), but only F. flavus survived up to 20‰ NaCl. For the antibacterial ability toward V. parahaemolyticus, two experiments using mycelium culture broth and mycofiltration were performed. Results revealed that all the three species of WDF effectively inhibited V. parahaemolyticus. Thus, mycelium culture broth of P. vitreis, S. commune, and F. flavus could inhibit 98.7, 96.5 and 97.8% V. parahaemolyticus, respectively after 8 hours. Even higher inhibitory effects were observed in the mycofiltration experiment, the efficiency reached 100% for P. vitreis, and 98% for F. flavus and S. commune after 8 hours. The obtained results showed very good application potential of myco-remediation technique using WDF in the treatment of V. parahaemolyticus in aquaculture farming. Mycofilter can be used as a new approach for controlling aquaculture disease, specifically Vibrio sp. treatment based on the antibiotic capability of these WDF. The reduction in pH of the mycelium broth can illustrated for the acidification during the mycelium development and could link with the bactericide capacity of these WDF.

Published: April 2018

Pigmented spore-forming bacterial strains were isolated from the gastrointestinal tracts of chickens for screening for heat-stable carotenoid-producing strains that could be applied as feed supplements. Of the seven heat-stable pigmented isolates screened, only two, yellow Sporosarcina saromensis CH1 and red-orange Bacillus aquimaris CH9, produced pigments with typical carotenoid absorbance peaks (400–500 nm). The CH9 carotenoids exhibited higher scavenging activity (73.2%) of DPPH free radicals than the CH1 carotenoids (35.9%) and carotenoids of the reference B. indicus HU36 strain (78.4%), in comparison to 100% activity of acid ascorbic at 18.75 M as the standard. The CH9 strain produced high levels of carotenoids (439 g [g DW]-1) and formed nearly 100% spores, whereas the CH1 strain produced low levels of carotenoids (92 g [g DW]-1) and only achieved 30% sporulation. Chromatographic and spectral profiles of the carotenoids found in CH9 indicated the presence of as many as 11 different carotenoid types closely related to 1-HO-demethylspheroidene and keto/hydroxyl derivatives of  carotene. We successfully produced concentrated orange CH9 spore powder at a high concentration of 6.1 × 1011 CFU g-1; these spores were much more heat-stable (66% survival at 80°C for 20 min) than the reference B. indicus HU36 spores (9% survival at 50°C for 20 min). In conclusion, B. aquimaris CH9 is a promising probiotic carotenoid-producing strain, with heat-stable spores that should withstand the heat-treatment processing required for feed and food supplement production.
Maternal Ideology in an MTN® Advertisement: Analysing Socio-Semiotic Reality as a Campaign for Peace
Authors: Dalamu Taofeek Olaiwola
Published: April 2018

It seemed that the issue of maternal ideology as a device to curb social menaces has not attracted scholars. Thus, the study examined the use of maternal ideology in mobile telephone network (MTN®) as a means of influencing recipients against vices instead of the primary assignment of the product advertising. The author utilised an advert of MTN, Sharing is good, as an object of analysis. The theoretical underpinning of the investigation was the concept of Theme as a functional approach to social semiotics. Theme interconnects the text with visual images to elucidate the meaning-making potential of the framework. The study revealed that the mother and the daughter operate in the same functional environment without any objections from either. The relationship demonstrates humility, complementarity, shareability and generosity. The message of the advert could influence corrupt elements of society such as terrorists, kidnappers, and violence campaigners to abandon nefarious acts and to embrace good behaviours. The idea propagated, perhaps, deserves voluntary emulation. Thus, the article argues that national and international stakeholders could make policy to direct advertising professionals to communicate their thoughts with materials that can support peace and harmony in our society. Such an exercise could persuade advertisers to reduce their focus on mental capitalism alone.

Sosyolojik açıdan insan, toplumsal düzenin

koşullamasıyla somutluk kazanmakla birlikte yeni toplumsal düzenin oluşmasında

da en etkin unsur olarak öne çıkar; çünkü insan, toplumsal bir varlık olarak,

içerisinde bulunduğu şartlardan ve kazandığı tecrübelerden hareketle yeni bir

toplumsal düzen planlaması yapabilir. Nitekim bugünkü modern toplum düzenini

bir yönüyle Rönesans, bir yönüyle de Aydınlanma Çağı düşünürlerinin eserlerinde

dolaylı veya dolaysız bir şekilde çizilen tasavvurlara borçlu olduğumuz

ortadadır. Fakat bazen söz konusu tasavvurlar, gerçeklik sınırının ötesinde

somutluk kazanır. İşte bu noktada ütopik bir tasavvur ortaya çıkar.

Oluşturulması arzu edilen toplumsal düzenin salt fikir düzeyinde kaldığı bu tür

tasavvurlar, tarihin başından beri mevcuttur. Fakat ütopyanın net ve bugün

anladığımız biçimde ortaya çıkışı, 16. yüzyılda Thomas More’un Ütopya’sıyla

başlar; 20. yüzyılda ise distopyaların ortaya çıkışıyla ütopik metinler, hiç

olmadığı kadar çeşitlilik arz edecek noktaya gelir. Bu incelememizde modern

Türk edebiyatında Çehov tarzı hikâyeciliğin öncülerinden olan Sait Faik

Abasıyanık’ın eserlerinde çoğunlukla örtük bir şekilde çıkan ütopik unsurlara

yoğunlaşılacak ve onun ütopyacı itkiyi aşmayan mutlu gelecek tasavvuru

sebepleriyle betimlenmeye çalışılacaktır.

GRAIN YIELD, FORAGE YIELD AND FORAGE QUALITY OF DUAL PURPOSE WHEAT AS AFFECTED BY CUTTING HEIGHTS AND SOWING DATE
Authors: ATIS İbrahim , AKAR Muzaffer
Published: April 2018

Dual purpose wheat production can help to produce the forage needed for livestock feeding, without reducing the sowing area of reserved for grain production. To determine the proper management techniques that reduce the loss of grain yield crops in dual purpose systems is very important. The objectives of this study were to investigate the effects of sowing date and cutting heights on grain yield, forage yield and nutritive value of dual-purpose wheat. The experimental design was split-plot under randomized complete block design, sowing dates (early, normal and late) as the main plot treatments and cutting heights (5, 7.5 and 10 cm) as the subplot treatments with three replications. Forage yield and forage protein yield were significantly affected by sowing date. Maximum forage yield and forage protein yield were obtained at normal sowing date (20 November) in both years, while maximum grain yield was obtained at early sowing date (20 October). The effect of sowing date on forage quality characters varied between years. Deeper cutting increased forage yield, while decreased grain yield. The effects of cutting heights on forage quality were different between years. The cutting treatments caused the decrease yield of the grain, but dual-purpose system for winter wheat was an advantageous crop system when evaluated in terms of the total amount of production. The height of 7.5 cm can be recommended as a suitable cutting height in term of the total crop quantity.
A (de)/(re)composição autobiográfica do corpo na poética de Começo, de Nathalie Quintane
Authors: Bertges Lívia Ribeiro , Pereira Vinicius Carvalho
Published: April 2018

O presente artigo apresenta uma leitura dos textos que compõem a série “Começo” na obra homônima de Nathalie Quintane, a qual se situa a meio do caminho entre a autobiografia e a poesia. Pretende-se aqui compreender como a composição, decomposição e recomposição do corpo humano é estruturada no livro como proposta de uma anatomia poética do eu. Nesse processo, delineiam-se como linhas de força o erótico e o abjeto como instâncias em que o eu se reconhece – e se desafia – como corpo e linguagem. Como balizas teóricas que respaldem tal leitura, elegem-se aqui as noções de pacto autobiográfico, de Lejeune (2014); de erotismo e escritura, de Barthes (1987); e de abjeção e significação, de Kristeva (1982). Destaque-se, por fim, que, como autobiografia e poesia, Começo propõe simultaneamente um percurso de formação e de deformação da primeira pessoa discursiva, como vias contrárias que se encontram no texto de Quintane.
O ator Julien Sorel
Authors: Ji Renan
Published: April 2018

O artigo faz uma releitura do romance O vermelho e o negro, de Stendhal, considerando a teatralidade como fator temático e procedimento narrativo. Mais especificamente, procura ver como a metáfora do ator pode esclarecer o destaque que o personagem ficcional ganha na narrativa e a relação deste com aspectos histórico-sociais do romance realista do século XIX. O personagem surge como elemento de tensão com o panorama histórico do romance, pois se imbui de uma carga trágico-heroica que foge do universo cultural burguês e remete ainda para a visão de mundo do antigo regime monárquico. Dialogando com alguns textos críticos e teóricos que se debruçaram sobre a obra e sobre o problema do personagem, este texto procura compreender a especificidade relacionada ao indivíduo inserido no tempo e no espaço romanescos.
O Romance: entre a história oficial e a alternativa
Authors: Salmistraro Renan
Published: April 2018

Este artigo analisa duas hipóteses distintas a respeito do desenvolvimento histórico do romance no Ocidente. A primeira delas, a que parece ser a mais célebre, pode ser sintetizada pelo estudo A ascensão do romance, de Ian Watt, que situa a origem do gênero romanesco na Inglaterra do século XVIII. No entanto, várias visões contrárias a essa tese surgiram no interior da própria crítica literária inglesa, especialmente os estudos de M. A. Doody (The True Story of the Novel: an Alternative History) e Michael McKeon (The Origins of the English Novel 1600-1740), apontando para uma “história alternativa” do romance, baseados no pressuposto de um desenvolvimento mais amplo da prosa de ficção, que remeteria aos textos da antiguidade e dos países orientais.
Influência da Mistura de Agregados Graúdos, Resíduo de Corte de Mármore e Granito e Metacaulim e Aditivos no Desempenho Mecânico do Concreto

A evolução dos estudos com relação às propriedades do concreto permitiu que os materiais fossem dosados de forma racionalizada, incluída a incorporação de resíduos provenientes do corte de mármores e granitos em sua produção, bem como foram desenvolvidos produtos específicos para melhorar seu desempenho. Neste trabalho produziu-se um concreto com intuito de estudar as propostas para melhorar o desempenho mecânico. Foi avaliada a influência da mistura de dois tipos de agregados graúdos de mesma origem mineralógica, a substituição de agregado miúdo por Resíduo de Corte de Mármore e Granito (RCMG) e a adição de Metaculim, fibras e aditivos visando elevar a resistência mecânica com relação ao traço de referência. Para tanto, foram realizados ensaios de resistência à tração e à compressão aos sete dias. Com os resultados obtidos foi possível perceber que a utilização de Metacaulim associada a um aditivo superplastificante apresentou o melhor desempenho, aumentando em 50% a resistência à compressão e não afetando a resistência à tração.Palavras-chave: Concreto.

The role of exosomal tetraspanins and proteases in tumor progression
Authors: Yunusova N.V. , Tugutova E.A. , Tamkovich S.N. , Kondakova I.V.
Published: April 2018

Major (CD9, CD63, CD81) and others (CD82, CD151, Tspan8) tetraspanins are widely represented in exosomes, where they interact with various proteins and form functional tetraspanin complexes. Tetraspanin complexes include proteases. Tetraspanin-associated exosomal proteases (ADAM proteases, MMPs, EMMPRIN) play an important role in the processes of cell motility, migration, invasion and formation of metastases. Also, a significant contribution to tumor progression is made by proteases that are not associated with tetraspanins. They destabilize intercellular contacts, promote migration and invasion of tumor cells, participate in the regulation of the expression IGF-I, VEGF and transcription factors activation/deactivation. The role of other proteases of exosomes in the processes of tumor progression is being clarified.
Ubiquitin-independent protein degradation in proteasomes
Authors: Buneeva O.A. , Medvedev A.E.
Published: April 2018

Proteasomes are large supramolecular protein complexes present in all prokaryotic and eukaryotic cells, where they perform targeted degradation of intracellular proteins. Until recently, it was generally accepted that prior proteolytic degradation in proteasomes the proteins had to be targeted by ubiquitination: the ATP-dependent addition of (typically four sequential) residues of the low-molecular ubiquitin protein, involving the ubiquitin-activating enzyme, ubiquitin-conjugating enzyme and ubiquitin ligase. The cytoplasm and nucleoplasm proteins labeled in this way are then digested in 26S proteasomes. However, in recent years it has become increasingly clear that using this route the cell eliminates only a part of unwanted proteins. Many proteins can be cleaved by the 20S proteasome in an ATP-independent manner and without previous ubiquitination. Ubiquitin-independent protein degradation in proteasomes is a relatively new area of studies of the role of the ubiquitin-proteasome system. However, recent data obtained in this direction already correct existing concepts about proteasomal degradation of proteins and its regulation. Ubiquitin-independent proteasome degradation needs the main structural precondition in proteins: the presence of unstructured regions in the amino acid sequences that provide interaction with the proteasome. Taking into consideration that in humans almost half of all genes encode proteins that contain a certain proportion of intrinsically disordered regions, it appears that the list of proteins undergoing ubiquitin-independent degradation will demonstrate further increase. Since 26S of proteasomes account for only 30% of the total proteasome content in mammalian cells, most of the proteasomes exist in the form of 20S complexes. The latter suggests that ubiquitin-independent proteolysis performed by the 20S proteasome is a natural process of removing damaged proteins from the cell and maintaining a constant level of intrinsically disordered proteins. In this case, the functional overload of proteasomes in aging and/or other types of pathological processes, if it is not accompanied by triggering more radical mechanisms for the elimination of damaged proteins, organelles and whole cells, has the most serious consequences for the whole organism.
