Accurate yet efficient high-throughput screenings have emerged as essential technology for enzyme engineering via directed evolution. Modern high-throughput screening platforms for oxidoreductases are commonly assisted by technologies such as surface display and rely on emulsification techniques to facilitate single-cell analysis via fluorescence-activated cell sorting. Empowered by the dramatically increased throughput, the screening of significantly larger sequence spaces in acceptable time frames is achieved but usually comes at the cost of restricted applicability. In this work, we tackle this problem by utilizing roGFP2-Orp1 as a fluorescent one-component detection system for enzymatic H2O2 formation. We determined the kinetic parameters of the roGFP2-Orp1 reaction with H2O2 and established an efficient immobilization technique for the sensor on Saccharomyces cerevisiae cells employing the lectin Concanavalin A. This allowed to realize a peroxide-sensing shell on enzyme-displaying cells, a system that was successfully employed to screen for H2O2 formation of enzyme variants in a whole-cell setting.Glyphosate, the active ingredient in RoundUp, is the most widely used herbicide on the globe, and has recently been linked to an increased risk in non-Hodgkin's lymphoma in exposed individuals. Therefore, detection and monitoring of glyphosate levels in water and soil is important for public safety. Here, we describe a biosensor for glyphosate based on an engineered Escherichia coli phosphonate-binding protein (PhnD). Mutations in the binding pocket were introduced to convert PhnD into a glyphosate-binding protein. A fluorescence group attached near the hinge of the protein was added to monitor binding of glyphosate and to determine its concentration in unknown samples. The resulting engineered biosensor can detect glyphosate in tap water and in soil samples treated with the herbicide at submicromolar concentrations, well below the limit for drinking water in the USA. Incorporating this biosensor in a device would allow rapid and continuous monitoring of glyphosate in water and soil samples.Cheap production of glucose is the current challenge for the production of cheap bioethanol. Ideal protein engineering approaches are required for improving the efficiency of the members of the cellulase, the enzyme complex involved in the saccharification process of cellulose. An attempt was made to improve the efficiency of the cellobiohydrolase (Cel6A), the important member of the cellulase isolated from Aspergillus fumigatus (AfCel6A). Structure-based variants of AfCel6A were designed. Amino acids surrounding the catalytic site and conserved residues in the cellulose-binding domain were targeted (N449V, N168G, Y50W and W24YW32Y). I mutant 3 server was used to identify the potential variants based on the free energy values (∆∆G). In silico structural analyses and molecular dynamics simulations evaluated the potentiality of the variants for increasing thermostability and catalytic activity of Cel6A. Further enzyme studies with purified protein identified the N449V is highly thermo stable (60°C) and pH tolerant (pH 5-7). Kinetic studies with Avicel determined that substrate affinity of N449V (Km =0.90 ± 0.02) is higher than the wild type (1.17 ± 0.04) and the catalytic efficiency (Kcat/Km) of N449V is ~2-fold higher than wild type. see more All these results suggested that our strategy for the development of recombinant enzyme is a right approach for protein engineering.
In April 2020, Covid-19 brought NHS elective procedures to a halt. The aim of this paper is to produce accurate forecasts on the building backlog, highlight the state of waiting lists currently and propose solutions required to prevent a public health crisis.

Using data published by NHS digital and NHS England on previous years, we have analysed and used this to produce estimates of cancellations and missed cases. We also analyse government data on waiting lists and show compliance or lack of with these.

We show that compliance with waiting list times pre pandemic was falling year on year (83.2% in 2020 down from 87% in 2019). Every month that passes we estimate that 400 000 cases are not being performed. This may include urgent cancer care work in some trusts.

Waiting lists have been governed by strict rules since 2004. Given falling compliance with 18-week intention to treat we believe the scale of the backlog combined with NHS capacity diminished due to Covid-19 precautions is a public health crisis waiting to occur. We identify difficulties in resuming elective work and suggest strategies that could be employed to avoid a public health crisis.

Bangladesh experienced its worst dengue fever (DF) outbreak in 2019. This study investigated the knowledge, attitudes and practices (KAP) among university students in Bangladesh and significant factors associated with their prevention practices related to climate change and DF.

A social media-based (Facebook) cross-sectional KAP survey was conducted and secondary data of reported DF cases in 2019 extracted. Logistic regression and spatial analysis were run to examine the data.

Of 1500 respondents, 76% believed that climate change can affect DF transmission. However, participants reported good climate change knowledge (76.7%), attitudes (87.9%) and practices (39.1%). The corresponding figures for DF were knowledge (47.9%), attitudes (80.3%) and practices (25.9%). Good knowledge and attitudes were significantly associated with good climate change adaptation or mitigation practices (p<0.05). Good knowledge, attitudes and previous DF experiences were also found to be significantly associated with good DF prevention practices (p<0.001). There was no significant positive correlation between climate change and DF KAP scores and the number of DF cases.

Findings from this study provide baseline data that can be used to promote educational campaigns and intervention programs focusing on climate change adaptation and mitigation and effective DF prevention strategies among various communities in Bangladesh and similar dengue-endemic countries.
