14 mg/g) was found in the leaves of P.×berolinensis. The antioxidant and xanthine oxidase inhibition properties of extracts from poplar leaves were investigated by TLC bioautography. It has been shown that the richest set of compounds with antioxidant properties are present in the leaves of P. alba, P.×candicans and P. nigra.The understanding of the functional importance of RNA has increased enormously in the last decades. This has required research on the RNA molecules themselves, with the concomitant need for obtaining purified RNA samples, such as for structural studies by NMR or other methods. The main method to create labeled and unlabeled RNA, T7 in vitro transcription, suffers from sequence-dependent yield and often low homogeneity for short constructs ( less then 100 nt) and requires laborious purification. Additionally, the design of structured RNA fragments mimicking the structure of a larger biological RNA is often not straightforward. Secondary structure simulations can be used to make reliable predictions about the folding of a particular RNA fragment. In this article, we describe how to design an RNA construct of interest from a larger sequence, and we combine several previously published improvements of the in vitro transcription method, such as the use of 2'-methoxy modifications and dimethyl sulfoxide or the use of tandem repeats, to increase yield and purity of in vitro-transcribed RNA. Together with a high-performance liquid chromatography (HPLC) purification procedure using both reversed-phase ion-pairing and ion-exchange HPLC, we provide a robust protocol to obtain highly pure RNA of short to intermediate length in large quantities. The protocol optimizes yield, especially for RNA starting with nucleotides other than G. At the same time, it is simplified, and the required time is reduced. The protocols described here constitute a versatile pipeline for the production of purified RNA samples and are suitable for users with little experience in liquid chromatography. © 2021 The Authors.

Little is known about the impact of COVID-19 and the United Kingdom's (UK) national shielding advice on people with cystic fibrosis (CF) and their families. This study explored the experiences and support needs of children and young adults (CYAs) with CF, and parents who have a child with CF, during the COVID-19 pandemic.

CYAs with CF and parents of CYAs with CF completed a UK wide online survey with open and closed questions exploring experiences, information and support needs and decision-making processes. Qualitative thematic content analysis and descriptive quantitative analyses were undertaken.

CYAs aged 10-30 years (n = 99) and parents of CYAs aged 0-34 years (n = 145) responded. Parents (72.7%) and CYAs (50.0%) worried about the virus, and both were vigilant for virus symptoms (82.7% and 79.7%). Over three-quarters of CYAs were worried about their own health if they caught the virus. CYAs worried about feeling more isolated during the virus (64.9%). Qualitative findings reported the following themes (1) Disruption-caused by isolation, (2) impact on psychological wellbeing, (3) safety of shielding, and (4) healthcare and treatment provision-changes to care, access and support.

The impact of COVID-19 and UK shielding advice to have no contact with anyone outside the household caused disruption to the lives and routines of individuals in relation to work, education, social lives, relationships, CF management routines and support. Parents and CYAs highlighted the need for clear, up-to-date and tailored advice on individualized risks and shielding.

Such profound changes can be understood by studying the biology of the organism and the interplay of the TEs it hosts. Characterizing and curating TEs across a wide range of species is a fundamental first step in this endeavor. This protocol employs techniques honed while developing TE libraries for a wide range of organisms and specifically addresses (1) the extension of truncated de novo results into full-length TE families; (2) the iterative refinement of TE multiple sequence alignments; and (3) the use of alignment visualization to assess model completeness and subfamily structure. © 2021 Wiley Periodicals LLC.

Yet, their dependency on visible light limits the cell-density, which is a challenge for the scale-up. Here, it was shown with the example of a light-dependent biotransformation that internal illumination in a bubble column reactor equipped with wireless light emitters (WLEs) could overcome this limitation. Cells of the cyanobacterium Synechocystis sp. PCC 6803 expressing the gene of the ene-reductase YqjM were used for the reduction of 2-methylmaleimide to (R)-2-methylsuccinimide with high optical purity (>99 % ee). Compared to external source of light, illumination by floating wireless light emitters allowed a more than two-fold rate increase. UNC0642 cost Under optimized conditions, product formation rates up to 3.7 mm h-1 and specific activities of up to 65.5 U gDCW -1 were obtained, allowing the reduction of 40 mm 2-methylmaleimide with 650 mg isolated enantiopure product (73 % yield).
