TL;DR: LLOV as mentioned in this paper is a fast, lightweight, language agnostic, and static data race checker for OpenMP programs based on the LLVM compiler framework, which can verify a C/C++ or FORTRAN program to be data race free.
Abstract: In the era of Exascale computing, writing efficient parallel programs is indispensable, and, at the same time, writing sound parallel programs is very difficult. Specifying parallelism with frameworks such as OpenMP is relatively easy, but data races in these programs are an important source of bugs. In this article, we propose LLOV, a fast, lightweight, language agnostic, and static data race checker for OpenMP programs based on the LLVM compiler framework. We compare LLOV with other state-of-the-art data race checkers on a variety of well-established benchmarks. We show that the precision, accuracy, and the F1 score of LLOV is comparable to other checkers while being orders of magnitude faster. To the best of our knowledge, LLOV is the only tool among the state-of-the-art data race checkers that can verify a C/C++ or FORTRAN program to be data race free.

TL;DR: The in vitro and in vivo toxicity studies on the mouse fibroblast cell line and rabbit skin surface respectively showed that the crude rhamnolipid mixture exhibits a nontoxic behavior, and the antimicrobial property with respect to bacteria was found to be more prominent toward Gram positive than towards Gram negative.
Abstract: Rhamnolipid is known for its potential for degradation of various harmful and toxic contaminants. However, there is a lack of reports of their effects on different biological systems. Hence, the present study focuses on the assessment of rhamnolipid mixture for their biocompatibility nature. The in vitro and in vivo toxicity studies on the mouse fibroblast cell line (L929) and rabbit skin surface respectively showed that the crude rhamnolipid mixture exhibits a nontoxic behavior (p < 0.05). Similar results were observed with Aedesalbo pictus larvae. However, studies on monocotyledonous and dicotyledonous seeds showed the toxic behavior of rhamnolipids above their critical micelle concentration values (5–200 mg.L − 1). The antimicrobial property with respect to bacteria was found to be more prominent toward Gram positive (0.5 ± 0.5 mg.L − 1) compared to Gram negative bacteria (2.0 ± 0.7 mg.L − 1) and it was least in case of fungi (2.0 ± 0.2 mg.L − 1). The present study opens up a possibility to stu...

TL;DR: The applications of ENM in plant biology with respect to nutrient management, regulation of plant growth, gene detection and preservation, disease diagnostics and control, and the techniques for enhanced analyses and controlled delivery of functional/bioactive molecules and decreased cytotoxicity are discussed.
Abstract: Plants are major contributors to the global food chain and provide ingredients such as carbohydrates, proteins, edible oils, dietary fibres, vitamins, minerals. They also provide us with, medicine, fabrics, building materials, biofuels, pulp, etc. Hence enhanced plant growth and health would directly contribute to the economy and development of nations. For this, a systematic understanding of plant biology is essential. From time to time plant biology has benefited immensely from various disciplines and platform technologies like genetics, breeding, microbiology and biotechnology, etc. Recently nanotechnology is contributing towards many discoveries in plant biology and utilization of plant resources. Nanomaterials (NM) are advantageous due to their characteristic dimension-based properties and amenability to real-time analyses with very low cost. They are used for monitoring plant metabolism and signalling pathways. NMs such as quantum dots (QD) serve as probes with unsurpassed accuracy. Engineered nanomaterials (ENM) have gained importance as bio-imaging agents, diagnostic tools for analysing plant pathogen interaction, nano-carriers for the delivery of genes and agrochemicals of interest. Here, we discuss the applications of ENMs in plant biology with respect to nutrient management, regulation of plant growth, gene detection and preservation, disease diagnostics and control. We also discuss the techniques for enhanced analyses and controlled delivery of functional/bioactive molecules and decreased cytotoxicity. We finally deliberate on emerging techniques associated with urban farming, precision agriculture, development of nanobionics.

TL;DR: The antimicrobial, skin surface moisturizing and low toxicity properties of glycolipid and lipopeptide biosurfactants which could make them suitable substitutes for chemical surfactants in current cosmetic and personal skincare pharmaceutical formulations are discussed.
Abstract: Cosmetic and personal care products are globally used and often applied directly on the human skin. According to a recent survey in Europe, the market value of cosmetic and personal care products in Western Europe reached about 84 billion euros in 2018 and are predicted to increase by approximately 6% by the end of 2020. With these significant sums of money spent annually on cosmetic and personal care products, along with chemical surfactants being the main ingredient in a number of their formulations, of which many have been reported to have the potential to cause detrimental effects such as allergic reactions and skin irritations to the human skin; hence, the need for the replacement of chemical surfactants with other compounds that would have less or no negative effects on skin health. Biosurfactants (surfactants of biological origin) have exhibited great potential such as lower toxicity, skin compatibility, protection and surface moisturizing effects which are key components for an effective skincare routine. This review discusses the antimicrobial, skin surface moisturizing and low toxicity properties of glycolipid and lipopeptide biosurfactants which could make them suitable substitutes for chemical surfactants in current cosmetic and personal skincare pharmaceutical formulations. Finally, we discuss some challenges and possible solutions for biosurfactant applications.

TL;DR: In this article, the antimicrobial activity of rhamnolipids against selected multidrug resistant bacteria and SARS-CoV-2 was investigated by growing Pseudomonas aeruginosa strain LeS3 on chicken carcass soup.
Abstract: COVID-19 is a pandemic disease caused by the SARS-CoV-2, which continues to cause global health and economic problems since emerging in China in late 2019. Until now, there are no standard antiviral treatments. Thus, several strategies were adopted to minimize virus transmission, such as social distancing, face covering protection and hand hygiene. Rhamnolipids are glycolipids produced formally by Pseudomonas aeruginosa and as biosurfactants, they were shown to have broad antimicrobial activity. In this study, we investigated the antimicrobial activity of rhamnolipids against selected multidrug resistant bacteria and SARS-CoV-2. Rhamnolipids were produced by growing Pseudomonas aeruginosa strain LeS3 in a new medium formulated from chicken carcass soup. The isolated rhamnolipids were characterized for their molecular composition, formulated into nano-micelles, and the antibacterial activity of the nano-micelles was demonstrated in vitro against both Gram-negative and Gram-positive drug resistant bacteria. In silico studies docking rhamnolipids to structural and non-structural proteins of SARS-CoV-2 was also performed. We demonstrated the efficient and specific interaction of rhamnolipids with the active sites of these proteins. Additionally, the computational studies suggested that rhamnolipids have membrane permeability activity. Thus, the obtained results indicate that SARS-CoV-2 could be another target of rhamnolipids and could find utility in the fight against COVID-19, a future perspective to be considered.
