Phi29 DNA polymerase (Phi29 Pol) has been successfully applied in DNA nanoball-based sequencing, real-time DNA sequencing from single polymerase molecules and nanopore sequencing employing the sequencing by synthesis (SBS) method. Among these, polymerase-assisted nanopore sequencing technology analyses nucleotide sequences as a function of changes in electrical current. This ionic, current-based sequencing technology requires polymerases to perform replication at high salt concentrations, for example 0.3 M KCl. Nonetheless, the salt tolerance of wild-type Phi29 Pol is relatively low. Here, we fused helix-hairpin-helix (HhH)2 domains E-L (eight repeats in total) of topoisomerase V (Topo V) from the hyperthermophile Methanopyrus kandleri to the Phi29 Pol COOH terminus, designated Phi29EL DNA polymerase (Phi29EL Pol). Domain fusion increased the overall enzyme replication efficiency by fourfold. Phi29EL Pol catalysed rolling circle replication in a broader range of salt concentrations than did Phi29 Pol, extending the KCl concentration range for activity up to 0.3 M. In addition, the mutation of Glu375 to Ser or Gln increased Phi29EL Pol activity in the presence of KCl. In this work, we produced a salt-tolerant Phi29 Pol derivative by means of (HhH)2 domain insertion. The multiple advantages of this insertion make it a good substitute for Phi29 Pol, especially for use in nanopore sequencing or other circumstances that require high salt concentrations.Most of the existing literature on environmental assessment has concentrated on the linkages between energy consumption and CO2 emissions, and little attention has been paid to the association between transport energy consumption and CO2 emissions, which cannot be underestimated. Therefore, the present study contributes to the literature on the sustainable transport sector and urban settlements in South Asian Association for Regional Cooperation (SAARC) countries through an analysis of annual data from 1996 to 2015. Two unit root tests revealed mixed orders of integration for all variables. The Kao cointegration test revealed a strong association among the variables. The panel mean group (PMG) estimator confirmed that urbanization and regulatory quality improve air quality in the SAARC region. Gross domestic product (GDP) and the use of transport energy lower air quality. Considering the role of transport energy use in increasing CO2 emissions, this study provides some policy implications for the sustainable transport sector in SAARC countries.

This sensor can convert multiple biomarker recognition into release of predesigned output nucleic acids tagged with streptavidin proteins (SA-DNA) for activation of DNA nanomachines. In general, we adopted complementary base pairing rules and affinity ligand specific recognition, and three types of signal conversion systems were constructed that realized universal, sensitive, accurate, and specific detection of multiple biomarkers. Taking the advantage of the strong anti-interference capability of magnetic separation, this strategy could be used for detection of various biomarkers in clinical practice.Traditional phenotyping methods, coupled with genetic mapping in segregating populations, have identified loci governing complex traits in many crops. Unoccupied aerial systems (UAS)-based phenotyping has helped to reveal a more novel and dynamic relationship between time-specific associated loci with complex traits previously unable to be evaluated. Over 1,500 maize (Zea mays L.) hybrid row plots containing 280 different replicated maize hybrids from the Genomes to Fields (G2F) project were evaluated agronomically and using UAS in 2017. Weekly UAS flights captured variation in plant heights during the growing season under three different management conditions each year optimal planting with irrigation (G2FI), optimal dryland planting without irrigation (G2FD), and a stressed late planting (G2LA). Plant height of different flights were ranked based on importance for yield using a random forest (RF) algorithm. Plant heights captured by early flights in G2FI trials had higher importance (based on Gini scores) for predicting maize grain yield (GY) but also higher accuracies in genomic predictions which fluctuated for G2FD (-0.06∼0.73), G2FI (0.33∼0.76), and G2LA (0.26∼0.78) trials. A genome-wide association analysis discovered 52 significant single nucleotide polymorphisms (SNPs), seven were found consistently in more than one flights or trial; 45 were flight or trial specific. Total cumulative marker effects for each chromosome's contributions to plant height also changed depending on flight. Using UAS phenotyping, this study showed that many candidate genes putatively play a role in the regulation of plant architecture even in relatively early stages of maize growth and development.
Osteogenesis imperfecta (OI) is a rare inherited heterogeneous connective tissue disorder characterized by bone fragility, low bone mineral density, skeletal deformity and blue sclera. The dominantly inherited forms of OI are predominantly caused by mutations in either the COL1A1 or COL1A2 gene. Collagen type I is one of the major structural proteins of the eyes and therefore is the eye theoretically prone to alterations in OI. The aim of this systematic review was to provide an overview of the known ocular problems reported in OI.

A literature search (in PubMed, Embase and Scopus), which included articles from inception to August 2020, was performed in accordance with the PRISMA guidelines.

The results of this current review show that almost every component of the eye could be affected in OI. Decreased thickness of the cornea and sclera is an important factor causing eye problems in patients with OI such as blue sclera. Findings that stand out are ruptures, lacerations and other eye problems that occur after minor trauma, as well as complications from standard surgical procedures.

Alterations in collagen type I affect multiple structural components of the eye. It is recommended that OI patients wear protective glasses against accidental eye trauma. Furthermore, when surgery is required, it should be approached with caution. The prevalence of eye problems in different types of OI is still unknown. Additional research is required to obtain a better understanding of the ocular defects that may occur in OI patients and the underlying pathology.
