FACTORS HINDERING TEACHERS FROM INTEGRATING NATURAL SCIENCES AND MATHEMATICS INTO HOME ECONOMICS COURSES
Authors: Torkar Gregor , Koch Verena
Published: March 2022

The purpose of this study was to examine the integration of natural sciences and mathematics into home economics teaching, particularly any factors hindering integration. Altogether 88 Slovenian home economics teachers were questioned. The results show that biology, consumer and health education were integrated into home economics courses more often than other subjects. Slovenian home economics teachers’ integration of other school subjects or topics depends mainly on their work experience and combination of subjects during their undergraduate studies. Another indicator, a negative one, was that our teachers didn’t know some relevant science and mathematics subject curricula and they are not enough competent in these sciences. This should be the first step in the future development of home economics teacher education.

Published: March 2022

A short look on any science center or science museum website reveals that significant amounts of online educational resources have been developed in recent years. However, how can the non-formal online learning resources of science centers/museums support learning activities inside schools? This study leverages the educational pathway of energy resources, designed by the European Open Science Resources project and the Deutsches Museum, to develop in-school learning activities. This research explores the impact of different instructional approaches incorporating the educational pathway, including the Self-Guided Educational Pathway (SGEP) and Teacher-Guided Educational Pathway (TGEP), on Taiwanese high-school students’ science learning outcomes. The results indicate that the TGEP approach provides students significantly higher knowledge gains than the SGEP approach. Moreover, the TGEP approach significantly maintained students’ positive attitudes toward science learning, museum learning, and online museum learning than did the SGEP approach. The results are discussed in terms of both pedagogical designs and the social culture of Eastern Asia.

Published: March 2022

Seven exotic varieties of advanced generation (Cimega, Farida, Jelly, Memphis, Panamera, Taisiya and 7four7) along with four checks (BARI Alu-7, BARI Alu-13, BARI Alu-25 and BARI Alu-28) of potato were evaluated at five agro-ecological locations of Bangladesh during 2016-17 to identify stable varieties for table and processing purposes. Results indicated significant variation among the varieties and locations. To identify the early bulking varieties, tuber yield at 65 DAP was recorded, which showed that the variety 7four7 gave maximum yield (28.1 t ha-1). So, it can be selected as an early market variety. The maturity period of the varieties varied from 85 to 95 days. At the final harvest (95 DAP), the highest average yield over location was also produced by 7four7 (38.7 t ha-1). The varieties Cimega and Memphis also gave comparable yields to that of 7four7 (37.3 and 36.7 t ha-1, respectively). Farida was found suitable for table purposes because of its high yield, medium-sized tubers, oval and smooth shape and good eating qualities. These four varieties were significantly better than the checks in yield. The variety Taisiya produced tubers with good size and shape but low in dry matter content. Memphis produced maximum large-sized tubers, and so it may be suitable for processing. All the varieties produced good dry matter (18-20%). From the AMMI stability analysis, Cimega and 7four7 were the most stable varieties. Taisiya and Memphis were found as medium stable. Based on the stability, tuber yield and other characters, these four varieties may be selected for further studies in the RYT before release as specific purpose varieties.

Effect of Spatial Arrangements on Yield and Competition of Jute (Corchorus Olitorius l.) and Mungbean (Vigna radiata l. Wilczek) in Intercropping
Authors: Chakraborty AK , Ghorai AK , Alam NM , Roy S , Saha R
Published: March 2022

Low profitability from jute farming, declining jute area and negligible pulse area are the rising concerns of farmers of Indo-Bangla subcontinent. This paper evaluated the extent of yield competition in jutemungbean intercropping with varying spatial geometry under alternate single row (SR) and double row (DR) planting. Two 2-year field experiments were conducted independently for the two systems of plantings involving jute (cv NJ 7010) and mungbean (cv TMB-37) arranged in systematic designs for 3×3×3 spacing and plant density combinations with three replications. Yield competition was assessed using indices. Intercropping was found productive and profitable compared to sole cropping. Land equivalent ratios (LER) and area × time equivalent ratios (ATER) always exceeded unity. Jute equivalent yield (JEY) increased in the range of 4.9-45.3% and 30.7-51.1% over sole jute fibre yield and mean monetary advantage index exceeded 27100 and 31800 ₹ ha-1 for SR and DR planting, respectively. Economic advantage was higher for spacing combinations of 40 cm (row to row) × 6.5-8 cm (jute to jute in a row) × 10-12 cm (mungbean to mungbean in a row) in SR planting and for DR system it was at a band-to-band spacing of 11 cm with plant densities of 40-50 m-2 for jute and 25-30 m-2 for mungbean. Dense and intimate planting of jute reduced mung seed yield due to light stress. DR planting seemed more advantageous.

Authors: Adhikari M , Mukhopadhyay M
Published: March 2022

In the present study, 9 bacterial and 6 fungal endophytes were isolated from surface sterilized leaf, stem and root samples of the medicinal plant - Andrographis paniculata (Kalmegh). The endophytes were screened for plant growth promoting traits (IAA, phosphate solubilization and N2 fixation), enzymes (cellulase and amylase) and antimicrobial compounds against 3 potent human pathogens- E. coli, Staphylococcus sp. and Vibrio sp. The majority of the isolated endophytes produced the phytohormone - IAA (ranging 2-45μg/ml), and 1 endophyte solubilized phosphate and fixed N2. All the fungal endophytes possessed cellulase and amylase activity. In the preliminary screening, 4 bacterial and 4 fungal endophytic isolates extract showed antagonistic activity against the 3 potent human pathogens which are known causative agents of urinary tract, skin and gastrointestinal tract infections, respectively. The endophytes of A. paniculata exhibiting broad and specific antimicrobial activity make them ideal candidates in medical purposes.

Published: March 2022

Physical education teachers are required to be creative in carrying out learning, especially if there are problems with sports facilities and infrastructure in schools. The learning model must be adaptive, especially to the limited facilities and infrastructure of physical education. In addition, the implementation of physical education learning, most of which still uses the drill method, cannot be used in physical education learning, especially if the facilities and infrastructure owned are limited, because it will create boredom in students because of the time waiting for their turn to do motion tasks. This article aims to determine the value of the content validity index (CVI) from development research to create a learning model for the basic skills of basketball passing for students which are expected to be a solution to the problems. The learning model that will be developed later is a learning model using traditional play and sports approaches. CVI was developed by education experts and has been widely used in sharing research to determine the validity of the content. Three experts consisting of education, basketball, and learning experts were asked to evaluate the development of a learning model for basic basketball passing skills. The results of expert validation on the development of a learning model of basketball passing basic skills obtained i-CVI was 0.867 and the average proportion of items considered relevant in the three experts was 0.8; 0.8; and 0.93. The conclusion of this study is the production of products that are declared valid and can be continued at the trial stage using learning materials for traditional games of Orekan, bentengan games, and cat and mouse games.  The implementation of this research is expected to be used by teachers in learning so that it is expected to improve basketball learning outcomes, especially the passing skills.

Published: March 2022

En Ecuador el financiamiento de proyectos sociales se logra mediante el aporte significativo de la recaudación tributaria, la misma que es vulnerable a efectos generados por variables económicas. El presente estudio plantea como objetivo determinar la incidencia de las variables económicas sobre la recaudación tributaria, mediante la aplicación de un modelo econométrico, para reflejar si éstas repercuten positiva o negativamente. Se obtienen datos de fuentes oficiales desde el año 2000 hasta 2020 y se realiza un modelo de Mínimos Cuadrados Ordinarios (MCO), cointegración de errores de Engle y Granger (1987) y un modelo de Mínimos Cuadrados Ordinarios Completamente Modificados (FMOLS) propuesto por Phillips y Hansen (1990). Los resultados muestran que la población total, tasa de empleo, PIB per cápita, presión fiscal e inflación inciden positivamente sobre la recaudación tributaria total. Mientras que, el índice de corrupción y presión fiscal al cuadrado tienen efecto negativo en la recaudación tributaria total. Las determinantes que mayor efecto positivo y negativo tienen sobre la recaudación tributaria total son el PIB per cápita con 3,035% e índice de corrupción con -0,282%. Por lo tanto, la toma de decisiones políticas en Ecuador debe direccionarse principalmente hacia el incentivo de la producción y combate a la corrupción.

Maxillofacial prostheses are among the modalities of prosthetic rehabilitation but the disinfectant solutions for their cleaning have been barely explored. The purpose of the present study was to evaluate the antibacterial effects of a Brazilian green propolis glycolic (PGL) solution on the removal of biofilm from the surface of two maxillofacial elastomers (room temperature vulcanization [RTV] and high consistency silicone rubber [HCR]). A total of 42 specimens (3×10 mm) were made with these two elastomers and Staphylococcus aureus was allowed to grow for 24 hours on the surface of the biomaterials. Specimens (n=3) were randomly allocated to the following treatment groups by immersion for 15 minutes: 0.9% saline solution; 2% chlorhexidine gluconate (CHX); 11%, 16% and 20% PGL; and Daro Brand® antimicrobial liquid agent and antibacterial gel soap. Quantitative assessment was performed by counting the number of colony-forming units (CFU). Two-way ANOVA was employed for data analysis. Specimens of both maxillofacial elastomers treated with PGL solutions at concentrations of 11%, 16% and 20%, as well as 2% CHX, did not reveal CFU/mL of the S. aureus strain, indicating the broad spectrum of antibiofilm action of these disinfectant solutions. In addition, the Daro Brand® antimicrobial liquid agent showed lower CFU/mL in both maxillofacial elastomers compared to the Daro Brand® gel soap and 0.9% saline solution. Therefore, disinfection with PGL solutions is effective and might be considered to be a promising alternative in eliminating the S. aureus biofilm from specimens of maxillofacial elastomers by immersion for 15 minutes.

Although implant rehabilitations are successful, a small portion of patients may present peri-implant mucositis and peri-implantitis due to the bacteria biofilm formation. The purpose of the present study was to evaluate the presence of Porphyromonas gingivalis (Pg), Prevotella intermedia (Pi), Fusobacterium nucleatum (Fn) and Scardovia wiggsiae (Sw) in Peri-implant gingival Fluid (PGF) of patients who received implants 12 months ago and associated with periodontitis (PD) history and clinical data. Samples were collected from 44 volunteers and analyzed by PCR with specific primers. The results showed that Pg were detected in 34%, Fn and Pi, 81.8%, and Sw 75% of the volunteers. Pg was frequently detected in patients who had a history of PD (p<0.05, q=8.19), but no statistically significant differences for Fn, Pi, and Sw (p>0.05, q<0.61). Pg was detected in 58.3% of the volunteers who had teeth prior to implants and their presence was associated with periodontitis (p<0.05, q=5.31) and gingivitis (p<0.05, q=4.31). All the patients whose probing depths were greater than 3 mm had Fn in detectable levels (p<0.05, q=4.56). In conclusion, the involvement of Sw in peri-implant alterations was not evident in this work. The presence of Pi and Fn were not related to history of PD and mucositis. Fn was present in periodontal pockets above 3 mm, suggesting its involvement in peri-implant alterations. Pg was detected in patients with a history of PD, gingivitis, and periodontitis and in those who had teeth before the implant installation.

Nossa proposta se enquadra em um momento marcado pela escassez de materiais e políticas que orientam a educação de surdos. Muitas vezes, incluídos em turmas mistas (com surdos e ouvintes), esses estudantes recebem conteúdos descontextualizados e que não exploram sua potencialidade de aprendizado, por meio do canal viso espacial (Silva et al., 2018; Rodrigues, 2018). Com base em uma pesquisa de abordagem qualitativa, realizamos uma revisão bibliográfica que integra conhecimentos sobre a educação de surdos e o uso da gamificação como recurso educativo buscando questionar: qual o potencial dos jogos para o ensino de língua portuguesa para estudantes surdos matriculados no Ensino Fundamental I? É possível desenvolver, com recursos limitados, um material pautado nas especificidades educacionais desses estudantes? Buscando responder a essas questões Desenvolvemos e apresentamos um Quis, desenvolvido com base no software PowerPoint. Para exemplificar a montagem e funcionamento do jogo, tematizamos em nosso material o ensino das expressões faciais, importante parâmetro para a formação de sinais em Libras. Concluímos ressaltando a importância da construção de materiais e oferecimento de formação adequada aos professores, voltada para estratégias desse tipo, tendo em vista a importância do aperfeiçoamento no uso do PowerPoint como ferramenta simples e versátil para a construção de jogos recurso educacional, diversificando as aulas e proporcionando aos alunos a utilização de instrumentos tecnológicos.
Environmental drivers of upper mesopelagic fish assemblages in the Benguela Upwelling System
Authors: Duncan SE , Sell AF , Hagen W , Fock HO
Published: March 2022

The Benguela upwelling system is one of the most productive marine ecosystems in the world; however, little is known about the community structure of mesopelagic fishes in its northern (nBUS) and southern (sBUS) subsystems. We analyzed around 1900 specimens from 13 stations in the nBUS and 11 stations in the sBUS during the austral summer and found 88 species and 24 families of mesopelagic fishes. Seven distinct assemblages characterized by water mass, oxygen concentration in the surface layer, and chlorophyll concentrations between 50 and 100 m were identified. The stations belonging to the nBUS shelf assemblage were low in oxygen concentration, had a mean abundance of 0.064 ind. 10 m-2, and were represented exclusively byDiaphus dumerilii. The sBUS shelf assemblage had a mean abundance of 15.00 ind. 10 m-2andMaurolicus walvisensisdominated. Two sBUS offshore assemblages had a mean abundance of 1.12 and 9.48 ind. 10 m-2. The most abundant taxa within the groups wereHygophum hanseni,Cyclothonespp., andD. meadi. Three nBUS offshore clusters had an abundance of 10.21, 11.88, and 14.19 ind. 10 m-2, andD. hudsoniprevailed in 2 groups, whileM. walvisensisdominated the third group. Our study provides insight into the environmental factors that drive the composition of mesopelagic fishes on the shelf and in the upper pelagic zone in these highly productive subsystems. Possible future changes in these subsystems, such as an expansion of the oxygen minimum zone, can thus be expected to affect certain mesopelagic taxa that are essential for the food web of the subsystems.

Movement is a key factor that shapes the distribution and structure of fish populations and influences the extent of the benefits provided by conservation and management measures, such as the implementation of marine no-take zones (NTZs). We used visual surveys and acoustic telemetry to investigate density and movement of 2 Brazilian endemic and highly targeted reef fish species inside and outside a coral reef NTZ, and subsequently inferred the effectiveness of the NTZ for protecting these species. To do so, visual surveys were performed on protected and unprotected reefs between 2016 and 2017. Moreover, 20 gray parrotfish Sparisoma axillare and 9 Brazilian snapper Lutjanus alexandrei were tagged with acoustic transmitters and passively monitored from December 2016 to October 2017. For both species, fish densities were significantly higher within the NTZ. Also, both species presented a high residence index over the short term, indicating they were full-time residents of the monitored area until detections were permanently lost. The absence of detections may indicate relocation to deeper reefs, predation, or fishing mortality when fish left the NTZ. Home ranges were small (0.10 to 0.45 km2), and both species presented spatially segregated subgroups within the populations. On average, the percentage of the home ranges within the NTZ was 88% for S. axillare and 95% for L. alexandrei. The results showed that small NTZs that are important to part of the life cycle of a target species are an effective measure to conserve reef fish populations, and also highlight the importance of fisheries management outside NTZs.

Published: March 2022

Carpal tunnel syndrome (CTS) is neuropathy that occurs due to compression of the median nerve in the carpal tunnel. Acromegaly is one of the important causes of CTS. The aim of this study was to examine median nerve with ultrasound in acromegalic patients and to assess the relationship with activity, duration of disease and body composition parameters. We prospectively examined the cross-sectional area (CSA) of the median nerve with high-resolution ultrasound in 107 acromegalic patients – control group (70 females and 37 males) and 107 healthy controls (70 females and 37 males) matched for age, gender, and BMI. Body composition parameters were assessed by dual-energy X-ray absorptiometry (DXA). The Student t-tests and Pearson correlation were used for data analysis. The cross sectional area of the median nerve was increased in acromegalic patients compared to controls (11.9±4.8 mm2 vs. 7.7±2.4 mm2, P<0.001). Positive correlation was found between IGF-1 levels and CSA in the acromegalic group (R = 0.400, P<0.001). Relationship between CSA and duration of acromegaly was not confirmed. In acromegalic patients, BMI correlated with the CSA (R=0.294, P=0.002). There was no significant difference in BMI, fat mass between the acromegalic and control group, but lean mass was higher in acromegalic patients compared with controls (54.8±13.3 vs. 51±11.6, P=0.047). Lean mass and LMI (total body lean mass/height) positively correlated with CSA in acromegalic patients (R=0.340, P<0.001; R=0.424, P<0.001). No correlation was observed between fat mass and CSA of median nerve in all groups. We confirmed the enlargement of the median nerve in acromegalic patients. This enlargement is proportional to the degree of IGF-1 levels and is not dependent on the duration of the disease. The enlargement of the median nerve in acromegalic patients also depends on lean body mass and is not dependent on fat body mass.
Coenzyme Q10 effects in neurological diseases
Authors: Rauchová H
Published: March 2022

Coenzyme Q10 (CoQ10), a lipophilic substituted benzoquinone, is present in animal and plant cells. It is endogenously synthetized in every cell and involved in a variety of cellular processes. CoQ10 is an obligatory component of the respiratory chain in inner mitochondrial membrane. In addition, the presence of CoQ10 in all cellular membranes and in blood. It is the only endogenous lipid antioxidant. Moreover, it is an essential factor for uncoupling protein and controls the permeability transition pore in mitochondria. It also participates in extramitochondrial electron transport and controls membrane physicochemical properties. CoQ10 effects on gene expression might affect the overall metabolism. Primary changes in the energetic and antioxidant functions can explain its remedial effects. CoQ10 supplementation is safe and well-tolerated, even at high doses. CoQ10 does not cause any serious adverse effects in humans or experimental animals. New preparations of CoQ10 that are less hydrophobic and structural derivatives, like idebenone and MitoQ, are being developed to increase absorption and tissue distribution. The review aims to summarize clinical and experimental effects of CoQ10 supplementations in some neurological diseases such as migraine, Parkinson´s disease, Huntington´s disease, Alzheimer´s disease, amyotrophic lateral sclerosis, Friedreich´s ataxia or multiple sclerosis. Cardiovascular hypertension was included because of its central mechanisms controlling blood pressure in the brainstem rostral ventrolateral medulla and hypothalamic paraventricular nucleus. In conclusion, it seems reasonable to recommend CoQ10 as adjunct to conventional therapy in some cases. However, sometimes CoQ10 supplementations are more efficient in animal models of diseases than in human patients (e.g. Parkinson´s disease) or rather vague (e.g. Friedreich´s ataxia or amyotrophic lateral sclerosis).

Extracellular DNA (ecDNA) activates immune cells and is involved in the pathogenesis of diseases associated with inflammation such as sepsis, rheumatoid arthritis or metabolic syndrome. DNA can be cleaved by deoxyribonucleases (DNases), some of which are secreted out of cells. The aim of this experiment was to describe plasma DNase activity in relation to extracellular DNA in adult rats, to analyse potential sex differences and to prove whether they are related to endogenous testosterone. Adult Lewis rats (n=28) of both sexes were included in the experiment. Male rats were gonadectomized or sham-operated and compared to intact female rats. Plasma ecDNA and DNase activity were measured using fluorometry and single radial enzyme diffusion assay, respectively. Concentrations of nuclear ecDNA and mitochondrial ecDNA were determined using real-time PCR. Females had 60% higher plasma DNase activity than males (p=0.03). Gonadectomy did not affect plasma DNase aktivity in males. Neither the concentration of total ecDNA, nor nuclear or mitochondrial DNA in plasma differed between the groups. No significant correlations between DNase aktivity and ecDNA were found. From previous studies on mice, it was expected, that male rats will have higher DNase activity. In contrast, our study in rats showed the opposite sex difference. This sex difference seems not to be caused by endogenous testosterone. Interestingly, no sex differences were observed in plasma ecDNA suggesting a complex or missing association between plasma ecDNA and DNase. The observed sex difference in plasma DNase aktivity should be taken into account in animal models of ecDNA-associated diseases.
Integrating Victim Perspective into the Nigerian Criminal Justice System Through an Assessment of Pre-Colonial Adjudicatory Process
Authors: Uthman Hambali Yahya Duro
Published: March 2022

The traditional methods of dealing with crimes among the early Nigerian communities accommodated the crime victim as a necessary party in the process. With the introduction of the English criminal justice system to Nigeria, the victim ceased to be a necessary party to trials. This article investigates the treatment of the victim in the two periods. With the aid of doctrinal methodology, the study finds the traditional method to be more comforting to the victim than the modern system. The article recommends reincorporating those aspects that are victim-friendly into the present Nigerian criminal justice system.
‘The moment is poorly chosen’: Proust, Same-Sex Sexuality and Nationalism
Authors: Blakeney Ty
Published: March 2022

This article attempts to think historically about the relationship between nationalism and same-sex sexuality in Proust's novel and in readers’ responses to the novel from the time of its publication to the present. The article uses a column written on the first part of Sodome et Gomorrhe by nationalist literary critic and author Binet-Valmer in 1921 in order to illuminate some of the sexual and political contexts of Proust's representation of same-sex sexuality. It then turns to two twenty-first-century uses of Proust by right-wing thinkers to theorize a particularly French, anti-communitarian, anti-politically correct form of homosexuality. Ultimately, these examples demonstrate that there is no one relationship between same-sex sexuality and nationalism or the national community; rather, same-sex sexuality often serves as a convenient tool for defining the national community and its outsiders, in a wide variety of ways that move beyond a simple equivalency between outlaw and gay.
«Новый мир» на краю деревни: родовые поместья и соседи
Authors: Андреева Ю.О.
Published: March 2022

Поселения родовых поместий (экопоселения) возникли в начале 2000-х годов под влиянием серии книг Владимира Мегре «Звенящие кедры России». Обычно они объединяют жителей, интересующихся идеями здорового образа жизни, органического земледелия и зачастую духовными поисками. На сегодняшний день в России насчитывается около 500 поселений в разных регионах, но в первую очередь в Европейской части и на юге страны. Желание построить «новый мир» – это одновременно и отказ от следования преемственности традиционному селу и попытка реконструировать национальный проект и образ жизни «далеких предков». Строителям родовых поместий необходимо создать всю инфраструктуру, договориться с соседями и администрацией, построить дом и придумать способ заработка вне города. Общение с местными жителями не входит в первоочередные задачи переселенцев, часто бывает посредник, который берет на себя контакты с органами власти и сельскими жителями. Приезжие встречают среди местных жителей непонимание и подозрения в сектантстве. Поселенцы позиционируют себя миссионерами, просвещающими местную публику. При этом, несмотря на колонизаторский пафос, сколько бы лет переселенцы ни прожили в селе, для местных жителей они все равно остаются чужаками и, по сути, не допускаются на общих основаниях к ресурсам села.
in English:
Settlements of kin’s domains (ecovillages) emerged in the early 2000s under the influence of Vladimir Megre’s series of books “The Ringing Cedars of Russia”. Usually, they unite people interested in healthy lifestyles, organic farming, and spiritual quests. Today there are about 500 settlements in different regions, but primarily in the European part and the south of Russia. The desire to build a “new world” is both a rejection of the traditional village and an attempt to reconstruct the national project and way of life of “distant ancestors”. Constructing a kin’s domain requires creating the entire infrastructure, negotiating with the neighbors and the administration, building a house, and figuring out a way to earn money outside the city. Communicating with local residents is not a priority for newcomers; there is often an intermediary who takes care of contacts with authorities and villagers. The newcomers face misunderstanding and suspicion of sectarianism among the locals. Settlers position themselves as missionaries enlightening the local public. At the same time, despite their colonialist pathos, no matter how many years settlers have lived in the village, they remain strangers to the locals and, in fact, are not allowed to access the village’s resources on general grounds.

In 2019, the novel highly infectious severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak rapidly led to a global pandemic with more than 346 million confirmed cases worldwide, resulting in 5.5 million associated deaths (January 2022). Entry of all SARS-CoV-2 variants is mediated by the cellular angisin-converting enzyme 2 (ACE2). The virus abundantly replicates in the epithelia of the upper respiratory tract. Beyond vaccines for immunization, there is an imminent need for novel treatment options in COVID-19 patients. So far, only a few drugs have found their way into the clinics, often with modest success. Specific gene silencing based on small interfering RNA (siRNA) has emerged as a promising strategy for therapeutic intervention, preventing/limiting SARS-CoV-2 entry into host cells or interfering with viral replication. Here, we pursued both strategies. We designed and screened nine siRNAs (siA1-9) targeting the viral entry receptor ACE2. SiA1, (siRNA against exon1 of ACE2 mRNA) was most efficient, with up to 90% knockdown of the ACE2 mRNA and protein for at least six days. In vitro, siA1 application was found to protect Vero E6 and Huh-7 cells from infection with SARS-CoV-2 with an up to ∼92% reduction of the viral burden indicating that the treatment targets both the endosomal and the viral entry at the cytoplasmic membrane. Since the RNA-encoded genome makes SARS-CoV-2 vulnerable to RNA interference (RNAi), we designed and analysed eight siRNAs (siV1-8) directly targeting the Orf1a/b region of the SARS-CoV-2 RNA genome, encoding for non-structural proteins (nsp). As a significant hallmark of this study, we identified siV1 (siRNA against leader protein of SARS-CoV-2), which targets the nsp1-encoding sequence (a.k.a. ‘host shutoff factor’) as particularly efficient. SiV1 inhibited SARS-CoV-2 replication in Vero E6 or Huh-7 cells by more than 99% or 97%, respectively. It neither led to toxic effects nor induced type I or III interferon production. Of note, sequence analyses revealed the target sequence of siV1 to be highly conserved in SARS-CoV-2 variants. Thus, our results identify the direct targeting of the viral RNA genome (ORF1a/b) by siRNAs as highly efficient and introduce siV1 as a particularly promising drug candidate for therapeutic intervention.
The Origin of Vasomotion and Stochastic Resonance in Vasomotion
Authors: Liu Shuhong , Zhao Liangjing , Liu Yang
Published: March 2022

Vasomotion is the spontaneous time-dependent contraction and relaxation of micro arteries and the oscillating frequency is about 0.01–0.1 Hz. The physiological mechanism of vasomotion has not been thoroughly understood. From the dynamics point of view, the heartbeat is the only external loading exerted on the vascular system. We speculate that the nonlinear vascular system and the variable period of the heartbeat might induce the low-frequency vasomotion. In this study, the laser Doppler flowmeter is used to measure the time series of radial artery blood flow and reconstructed modified time series that has the same period as the measured time series but different heartbeat curves. We measured the time series of radial artery blood flow in different conditions by adding different noise disturbances on the forearm, and we decomposed the experiment pulse signal by Hilbert–Huang transform. The wavelet spectral analyses showed that the low-frequency components were induced by the variable period but independent of the shape of the heartbeat curve. Furthermore, we simulated the linear flow in a single pipe and the nonlinear flow in a piping network and found that the nonlinear flow would generate low-frequency components. From the results, we could deduce that the variable period of heartbeat and the nonlinearity of the vascular system induce vasomotion. The noise has effects on the blood signals related to the respiratory activities (∼0.3 Hz) but little influence on that related to the cardiac activities (∼1 Hz). Adding white noise and then stopping would induce an SNR increase in the frequency band related to vasomotion (∼0.1 Hz).
