description: BACKGROUND: The highly infectious nature of SARS-CoV-2 necessitates using bio-containment facilities to study viral pathogenesis and identify potent antivirals. However, the lack of high-level bio-containment laboratories across the world has limited research efforts into SARS-CoV-2 pathogenesis and the discovery of drug candidates. Previous research has reported that non-replicating SARS-CoV-2 Spike-pseudotyped viral particles are effective tools to screen for and identify entry inhibitors and neutralizing antibodies. METHODS: To generate SARS-CoV-2 pseudovirus, a lentiviral packaging plasmid p8.91, a luciferase expression plasmid pCSFLW, and SARS-CoV-2 Spike expression plasmids (Wild-type (D614G) or Delta strain) were co-transfected into HEK293 cells to produce a luciferase-expressing non-replicating pseudovirus which expresses SARS-CoV-2 spike protein on the surface. For relative quantitation, HEK293 cells expressing ACE2 (ACE2-HEK293) were infected with the pseudovirus, after which luciferase activity in the cells was measured as a relative luminescence unit. The ACE2-HEK293/Pseudovirus infection system was used to assess the antiviral effects of some compounds and plasma from COVID-19 patients to demonstrate the utility of this assay for drug discovery and neutralizing antibody screening. RESULTS: We successfully produced lentiviral-based SARS-CoV2 pseudoviruses and ACE2-expressing HEK293 cells. The system was used to screen compounds for SARS-CoV-2 entry inhibitors and identified two compounds with potent activity against SARS-CoV-2 pseudovirus entry into cells. The assay was also employed to screen patient plasma for neutralizing antibodies against SARS-CoV-2, as a precursor to live virus screening, using successful hits. SIGNIFICANCE: This assay is scalable and can perform medium-to high-throughput screening of antiviral compounds with neither severe biohazard risks nor the need for higher-level containment facilities. Now fully deployed in our resource-limited laboratory, this system can be applied to other highly infectious viruses by swapping out the envelope proteins in the plasmids used in pseudovirus production.

title: Effect of human epidermal growth factor receptor 2 signalling on the IFN-γ pathway in luminal B breast cancer

description: Previous studies showed luminal B (Human epidermal growth factor 2 +(HER2+) Estrogen receptor + (ER+) human breast carcinomas, compared to other breast cancer subtypes, are deficient in human leukocyte antigen (HLA) expression. Similarly, representative breast cancer cell line BT-474 (HER2+ER+) exhibited significantly reduced IFN-γ-inducible HLA expression, as compared to MCF-7 (HER2-ER+) and SKBR3 (HER2+ER-). Therefore, we hypothesized hyperactivation of HER2 signalling in ER+ breast cancer may interfere with interferon gamma (IFN-γ) pathway activation. To test this hypothesis, time course studies, targeted inhibition of HER2 (lapatinib or trastuzumab+pertuzumab) and ER (tamoxifen and ICI) and small interfering RNAs (siRNAs) targeting HER2 (ERBB2) and/or ER (ESR1) pathways were performed. Changes in IFN-γ pathway components, HER2, ER and HLA Class I in BT-474 and SKBR3, were assessed by flow cytometry and western blotting. Kinetic studies showed no clear inverse correlation between HER2 levels and surface HLA Class I while HER2 inhibition or knockdown resulted in reduced surface interferon gamma receptor 1 (IFNGR1) and HLA Class I. Neither phosphorylated signal transducer and activator of transcription (pSTAT- 1) nor interferon regulatory factor 1 (IRF-1) were significantly altered in BT-474 or SKBR3. The results suggest expression levels and/or function of IFN-γ pathway proteins may be dysregulated, likely independent of HER2 overexpression, resulting in weak IFN-γ signalling in BT-474 (HER2+ER+) and subsequent poor HLA Class I upregulation.

description: The CH2Cl2/MeOH (1:1) extract of the aerial parts of Tephrosia subtriflora afforded a new flavanonol, named subtriflavanonol (1), along with the known flavanone spinoflavanone B, and the known flavanonols MS-II (2) and mundulinol. The structures were elucidated by the use of NMR spectroscopy and mass spectrometry. The absolute configuration of the flavanonols was determined based on quantum chemical ECD calculations. In the antiplasmodial assay, compound 2 showed the highest activity against chloroquine-sensitive  Plasmodium falciparum reference clones (D6 and 3D7), artemisinin-sensitive isolate (F32-TEM) as well as field isolate (KSM 009) with IC50 values 1.4–4.6 μM without significant cytotoxicity against Vero and HEp2 cell lines (IC50 > 100 μM). The new compound (1) showed weak antiplasmodial activity, IC50 12.5–24.2 μM, but also showed selective anticancer activity against HEp2 cell line (CC50 16.9 μM).

description: A new group of ureylbenzamide-based receptors (1–4) has been synthesized; its binding affinity and capacity to form supramolecular complexes in solution with different anions have been investigated. For designing these receptors, it was considered a combination of the positions of the urea and amide groups (ortho and meta), and the chromophore groups naphthyl and nitrophenyl, yielding four receptors. The position and chromophore structure affected the acidity of the urea and amide hydrogens in the order 4>3>2>1. All the spectroscopic studies showed a significant change of 1 and 2 compared with 3 and 4 in the presence of different TBAX salts in acetonitrile. The 1H-NMR spectra show a preferential interaction of the anions with the urea group in receptors 1 and 2 due to the less steric hindrance, while there is a cooperative interaction of amide group in receptors 3 and 4 due to the closeness of both groups.

description: The aim of the present study was to determine whether Cassia tora extracts could reverse the oxidative stress-induced neurodegeneration in a Parkinson’s disease in vitro model. The leaves were treated with ethyl acetate (CtEA) or methanol (CtME). The extracts were first analysed by HPLC for their phenolic content and then tested for their neuroprotective effects in human SK-N-SH neuroblastoma cells. Cells were pre-treated with various concentrations of extracts followed by incubation with paraquat (14 μM). Firstly, pre-treatment of SK-N-SH cells with 100 μg/mL of CtEA or CtME significantly reduced the paraquat-induced production of reactive oxygen species. Furthermore, both CtEA and CtME reduced the paraquat-induced apoptosis. Moreover, there was a significant reduction of paraquat-induced DNA damage in SK-N-SH cells pre-treated with CtEA or CtME. Finally, both extracts significantly inhibited paraquat-dependent lipid peroxidation. Altogether, these in vitro data establish C. tora as a possible anti-Parkinson natural remedy.

All the complexes were characterized by IR, 1H, 13C, 119Sn NMR spectra, elemental analysis, X-ray single crystal diffraction and TGA. For in vitro antitumor activities, complexes were evaluated by the MTT assay against three human cancer cell lines (NCI-H460, HepG2 and MCF7) and human cell line (HL7702). The results showed that 1 may be a better potential candidate for further chemical optimization and cancer therapy than 2 and 3. The interactions between the complexes and calf thymus DNA were studied; the interaction of 1 with calf thymus DNA was intercalation, 2 and 3 were intercalation and electrostatic binding.

title: Specific PIP2 binding promotes calcium activation of TMEM16A chloride channels
Creators: name: Jia, Zhiguang
name: Chen, Jianhan
Publisher: name: University of Massachusetts Amherst
Year: 2021

description: TMEM16A is a widely expressed Ca2+-activated Cl− channel that regulates crucial physiological functions including fluid secretion, neuronal excitability, and smooth muscle contraction. There is a critical need to understand the molecular mechanisms of TMEM16A gating and regulation. However, high-resolution TMEM16A structures have failed to reveal an activated state with an unobstructed permeation pathway even with saturating Ca2+. This has been attributed to the requirement of PIP2 for preventing TMEM16A desensitization. Here, atomistic simulations show that specific binding of PIP2 to TMEM16A can lead to spontaneous opening of the permeation pathway in the Ca2+-bound state. The predicted activated state is highly consistent with a wide range of mutagenesis and functional data. It yields a maximal Cl− conductance of ~1 pS, similar to experimental estimates, and recapitulates the selectivity of larger SCN− over Cl−. The resulting molecular mechanism of activation provides a basis for understanding the interplay of multiple signals in controlling TMEM16A channel function.

description: The presence of Escherichia coli and Staphylococcus spp. was determined on the skin, personal protective equipment, the municipal vehicle, and various surfaces at ten households in a peri-urban community (KwaZulu-Natal, South Africa) before and after manual emptying of ventilated improved pit latrines. Surface samples (n = 14) were collected using sterile wet wipes, and target bacteria were detected using standard procedures. Additionally, E. coli was enumerated in soil samples from an area of open defecation (log10 3.7 MPN/g) and areas where geophagia occurred (log10 2.7 – log10 3.3 MPN/g), using a most probable number (MPN) method. The detection frequency for the target bacteria on household surfaces (e.g., the walkway between the pit latrine and the municipal vehicle) and on municipal workers’ hands (which were frequently contaminated before pit emptying), occasionally increased after the pits were emptied, indicating that manual pit emptying might pose a potential health risk to workers and community members.

description: Salmonella in the environment have evolved genetically to maintain a stable cell metabolism. Nevertheless, a lack of common nutrients (such as glucose) causes these strains to metabolize alternative carbon sources. In this study, 21 strains of Salmonella Oranienburg isolated from subtropical river water were evaluated to compare their adaptation and preconditioning abilities for the consumption of environmental carbon sources (ECS). The results obtained in this study attributed important biological characteristics to the adaptation of the metabolism of Salmonella strains to diverse ECS; these characteristics include but are not limited to variations in plasticity and natural preconditioning in closely related microorganisms, such as environmental isolates belonging to the serotype Oranienburg.

description: In this study, we investigated the total arsenic concentration in the soil and the related human exposure risks in the central part of the Bardsir Plain in southeastern Iran. The results show that the average total arsenic concentration in agricultural soil is 50.26 mg/kg, which is 2.5 times higher than the maximum acceptable limit (20 mg/kg) recommended by the European Community. The natural portion of the arsenic concentration was larger than the anthropogenic portion. The high total arsenic concentration could be due to a combination of geogenic sources and irrigation with polluted groundwater. The average values of Igeo, Ipoll, and IB for agricultural soils were 1.10, 0.14, and 0.15, respectively; which are characterized as moderately polluted. The average non-carcinogenic hazard (HI) values for children and adults were 2.27 and 0.24, respectively, suggesting that children are exposed to non-carcinogenic risks. The total carcinogen risk (CR) value was 1.16E−04, which indicates a high risk of harmful effects to inhabitants.

description: Facial expression is the most natural means for human beings to communicate their emotions. Most facial expression analysis studies consider the case of acted expressions. Spontaneous facial expression recognition is significantly more challenging since each person has a different way to react to a given emotion. We consider the problem of recognizing spontaneous facial expression by learning discriminative dictionaries for sparse representation. Facial images are represented as a sparse linear combination of prototype atoms via Orthogonal Matching Pursuit algorithm. Sparse codes are then used to train an SVM classifier dedicated to the recognition task. The dictionary that sparsifies the facial images (feature points with the same class labels should have similar sparse codes) is crucial for robust classification. Learning sparsifying dictionaries heavily relies on the initialization process of the dictionary. To improve the performance of dictionaries, a random face feature descriptor based on the Random Projection concept is developed. The effectiveness of the proposed method is evaluated through several experiments on the spontaneous facial expressions DynEmo database. It is also estimated on the well-known acted facial expressions JAFFE database for a purpose of comparison with state-of the-art methods.

description: In the past decades, the field of cinema has undergone several transformations. The digital turn increasingly called for new forms of production, distribution, and exhibition, which imply different ways of thinking, doing, and experimenting cinema. These new forms also reduced the gap between cinema to other so-called visual arts. If cinema and visual arts were already in the process of merging, the last years forced the naturalization of thinking in similar theoretical grounds. This special issue aims to be a forum for the discussion of new practices of researching cinema, and the changes in cinema’s forms of experience and production.

description: Enhancement of the transesterification efficiency of triglyceride has come under heated study in biodiesel-making industry. In this research, the NiMo/La-Al2O3 nanopowders have been prepared for producing biodiesel efficiently. The screening test showed that the NiMo/La-Al2O3 catalyst has the best catalytic activity for triglyceride transesterification. Besides, the process parameters including reaction temperature, time, oil-to-alcohol ratio and catalyst loading etc., also have been investigated for optimization of the transesterification process. The results showed that with 5 wt% of catalyst loading, and oil to methanol molar ratio of 1:9, the conversion yield of triglyceride could be up to 95.2% within 120 min at 160°C. The NiMo/La-Al2O3 catalyst has the outstanding recycle property, which proved that the prepared NiMo/La-Al2O3 powders can be suitable for biodiesels’ production.

description: Alfred Hitchcock's Rebecca is part of the series of 1940s gothic films. In this essay, one of the most common tropes of this subgenre of the psychological thriller is identified and analysed: perceptual ambiguity. Based on this element, I justify the formal choices of an (audio)visual essay - "Some Visual Thought about Perception in Rebecca" - made with images and sound from that film, which explores the gothic dimensions of the video-essayistic practice itself: research, contradiction, quotation and evocation.

description: Air pollution is associated with several detrimental health conditions. This study assessed comfort parameters, priority air pollutants, hydrogen sulphide (H2S), non-methane hydrocarbons (NMHCs), and volatile organic compounds (VOCs) in natural science departments in a university to understand their role in air pollutant concentrations in university environments and associated health risks. Levels of air pollutants in the departments varied. High CO2 concentrations existed in all departments with highest levels of NMHC and VOC observed in the biochemistry, microbiology and biotechnology (BMBT) department. Highest Air quality index value of 111.3 was recorded for NO2 in the BMBT department. Health risk associated with exposure to these pollutants was highest for occupants in the physiology, followed by the biodiversity, and finally BMBT department. Natural science departments seem to contribute significant amounts of H2S, NO2, NMHCs and TVOCs in university campuses. Additional ventilation and frequent monitoring of air quality in these departments are recommended.

Publisher: name: Journal of Science and Technology of the Arts
Year: 2020

description: The beginning of an audiovisual section in the Journal of Science and Technology of the Arts has two main goals: the first one is for contributing for the acceptance of these objects in the academic field, especially within the most common practices and criteria of acceptance, reviewing and publishing. For this, we’ll have in each number a call for audiovisual essays, that will be submitted to a peer-reviewed system of evaluation. Each audiovisual essay will be accompanied by a research statement written by the author, articulating research aims and the process of work. After acceptance, the audiovisual essay and author’s statement will be published alongside the reviewers’ critical evaluation of the work; the second goal of this section will be to create a conceptual discussion around audiovisual essay as a pedagogical and academic tool, in order to generate concepts and criteria for evaluation and scientific consideration.

Situating a Non-Conformist Auteur
Creators: name: Austin, Thomas
Publisher: name: Journal of Science and Technology of the Arts
Year: 2020

description: This review of Nuno Barradas Jorge’s monograph The Films of Pedro Costa welcomes its detailed account of hitherto neglected dimensions of Costa’s work, such as funding, relations with producers, technological aspects of production and postproduction, and the promotional labour of Costa’s media interviews. But it argues that these undoubtedly useful insights come at the expense of sustained close attention to Costa’s striking imagery and use of sound. The most glaring absences in the book are those of racial and class politics, and hence the interface between the two. Jorge’s book is an important contextual study of Costa’s oeuvre, but the immense aesthetic and political power of this filmmaking (both texts and collaborative processes of production) still eludes his grasp.

Folk Dancing Documentation as a Creative Tool for Video Art
Creators: name: Christidis, Yiannis
name: Synnos, Nicos
Publisher: name: Journal of Science and Technology of the Arts
Year: 2020

description: This paper explores how both sound and image of a documentary under production footage can serve as a narrative tool for a sound-oriented video art piece (‘Folkofolk’), and at the same time communicate the ideas of the final documentary itself. It discusses possible uses of existing footage derived from an ethnographic documentary in production, which maps and records the existence of German-speaking folk dancing groups. The information of the gathered original footage seeks to understand how the notion of place is interpreted through the folk dancing soundscape as a whole, and wishes to highlight the everyday sound's social character. The footage of ‘Folkofolk’ features recordings of assorted German-speaking folk dancing groups in Berlin and Vienna. Based on the social properties of place, ‘Folkofolk’ seeks to explore, in a wider level, an alternative narrative of how folk dancing soundscapes potentially create a sense of place and community through creative film editing practices that are close to video art.

description: We investigate the climatic influence on COVID-19 transmission risks in 228 cities globally across three climatic zones. The results, based on the application of a Boosted Regression Tree algorithm method, show that average temperature and average relative humidity explain significant variations in COVID-19 transmission across temperate and subtropical regions, whereas in the tropical region, the average diurnal temperature range and temperature seasonality significantly predict the infection outbreak. The number of positive cases showed a decrease sharply above an average temperature of 10°C in the cities of France, Turkey, the US, the UK, and Germany. Among the tropical countries, COVID-19 in Indian cities is most affected by mean diurnal temperature, and those in Brazil by temperature seasonality. The findings have implications on public health interventions, and contribute to the ongoing scientific and policy discourse on the complex interplay of climatic factors determining the risks of COVID-19 transmission.
Image and racism: Racial anthropophagy and the limits of anti-racist and decolonial cultural production in Brazil
Creators: name: Sales, Michelle
name: Muniz, Bruno
Publisher: name: Journal of Science and Technology of the Arts
Year: 2020

description: In this article, we intend to talk about the representation of black people in Brazilian cinema, pointing out how hegemonic images of Brazilian cinema corroborate the structural racism of our society, analyzing films (and other visual narratives) from the 2000s, a period considered the "Resumption of Brazilian Cinema". Cinema produced by black directors emerges as counter-narratives, deepening the way in which Brazilian cinema represents the racial issue in Brazil in a stereotyped way. To think about this structural racism in the field of cinema we will deepen the concept of racial anthropophagy (Amparo, 2018; Paixão, 2015) a kind of aesthetic of the flesh, in which the image of the "other" (the black or black) is appropriate and devoured in the name of art. We will also seek to dialogue with black feminism in Brazil, emphasizing the specificity of this field and discussing image production around black women in Brazil.

description: A s tudy was conducted to investigate the aquatic insect communities in Universiti Malaysia Sabah (UMS), Sabah, Malaysia. Two sampling sites were selected: lakes at School of Science and Technology (SST), and another near College E (CE) (student accommodation). Each lake consisted of four sampling stations. Aquatic insects were sampled using dip net from November 2013 to January 2014. Four water quality parameters were measured at each station. Shannon-Weiner’s diversity index and biotic indices (BMWP) were used in this study. Student’s t-test was used for testing the significant difference of water quality parameters, Shannon-Weiner’s diversity index and BMWP between these lakes. Pearson’s correlation was used to investigate relationships between aquatic insect assemblage and water quality parameters. A total of 1987 individuals composed of five orders that representing eleven families were recorded in this study. Baetidae (56.67%) was the dominant family in UMS, where Diptera order had least abundant with only 0.4% of overall sample. Aquatic insect abundance were significantly higher (P<0.05) in CE Lake. Bray-Curtis Similarity index showed 53.75% similarity between these two lakes. Pearson’s correlation showed that aquatic insect abundance and richness had significant relationships with water temperature, dissolved oxygen, salinity and pH (P<0.05 or 0.01), except for salinity with taxa richness. Based on Malaysia’s INWQS, water quality parameters of these two lakes were categorized as Class I, but with dissolved oxygen the CE and SST lakes were classified as Class IIA and III respectively. The BMWP index showed similar results as dissolved oxygen, where SST Lake (score=40) had poor water quality.

description: The objective of the study was to assess the prevalence and factors associated with household (HH) handwashing practice in Bangladesh and draw a trend of COVID-19 spreads and compare that with the countrywide HH handwashing practice. The study is based on the two national representative publicly available datasets (MICS 2019, and confirmed cases of COVID-19). Of 61,209 (weighted) HH, the overall prevalence of HH handwashing was found 56.3%, and the prevalence was significantly varied across the socio-economic status of the HH. Map comparison suggested that the gradual increasing trend of COVID-19 cases in areas where HH handwashing practice is low. The northern part of Bangladesh had the highest handwashing practice, whereas it had less effected by COVID-19 cases. However, central Bangladesh had the hardest hit by COVID-19 cases, and it had around 50% handwashing practice coverage. Large-scale observational study is necessary to establish the causality.
Land use influence on the aquatic insect communities on tropical forest streams of Liwagu River, Sabah, Malaysia

Subjects: subject: Ecology
subject: FOS: Biological sciences

description: The diversity of aquatic insect communities from three types of land use (forest, agricultural and urban development) of Liwagu River, Sabah was investigated to study the relationships between aquatic insects with physico-chemical parameters and habitat quality parameters. Two stations of the forest area recorded highest species richness, abundance and proportion of sensitive aquatic insects taxacompared to the agricultural and urban development area. Cluster analysis illustrated the association of aquatic insect communities with the three types of land use. The functional feeding group of collector-gatherer and collector-filterer were dominant in all sampling stations. The results of the canonical correspondence analysis (CCA) shown the physico-chemical parameters (dissolved oxygen, temperature, phosphate, nitrate and conductivity) in addition to habitat quality assessment (canopy cover, epifaunal substrate, bank stability, vegetative protection, riparian vegetation zone and total habitat assessment) were the important factors that affecting the diversity of aquatic insect communities at Liwagu River, Sabah, Malaysia.

Contemporary Cinema and the Logic of the Building The Case of Apichatpong Weerasethakul’s "Loong Boonmee raleuk chat"
Creators: name: Natálio, Carlos
Publisher: name: Journal of Science and Technology of the Arts
Year: 2020

description: This paper problematizes the use of the concept of contemporary to describe a specific modus operandi of a group of directors and films that no longer identify with the characteristics of modern cinema. Using the symbolic date of 9/11 as an historical decisive moment, we take as an example of this cinema, Loong Boonmee raleuk chat, winner of 2010’s Palme D’Or at Cannes Film Festival. In analysing Apichatpong Weerasethakul’s film, we aim at proposing, as a metaphor, a different approach - a logic of the building - in order to describe the specific creative processes in contemporary cinema. In order to describe the Thai filmmaker’s method, we will recuperate Giorgio Agamben’s ideas about what it means to be contemporary, and also the ethical responsibility of cinema in helping to recover the lost gestures of humanity.

Hallucinating Gonçalo M. Tavares’ "Short Movies"
Creators: name: Eiras, Pedro
Publisher: name: Journal of Science and Technology of the Arts
Year: 2020

description: Short Movies, by the Portuguese author Gonçalo M. Tavares (2011), is hard to define in the field of literary or artistic genres. There are no movies in this book, just verbal descriptions of possible movies, usually marked by intense violence; but these descriptions, in turn, resemble to cinematic scripts, suggesting a set of shots, camera movements, the grammar of a montage. In this hybrid way of writing, the film is an object that remains both present and absent, continually summoned and always deferred. What operation is then required of the reader of this book, what gesture between reading and seeing, what theory of epistemology, what kind of controlled hallucination? In short, this essay proposes that Short Movies invites to the development of a subtle and painful art of suspicion.
