H2 as a fuel for flavin- and H2O2-dependent biocatalytic reactions

The soluble hydrogenase from Ralstonia eutropha provides an atom efficient regeneration system for reduced flavin cofactors using H2 as an electron source. We demonstrated this system for highly selective ene-reductase-catalyzed C[double bond, length as m-dash]C-double bond reductions and monooxygenase-catalyzed epoxidation. Reactions were expanded to aerobic conditions to supply H2O2 for peroxygenase-catalyzed hydroxylations.DFG, 284111627, H2-basierende Kaskaden für die Biosynthese von N-HeterocyclenDFG, 405325648, ,Engineering von O2-toleranten Hydrogenasen und ihre physiologischen Auswirkungen in rekombinanten Bakterien im Hinblick auf die Hydrogenase-abhängige NAD(P)H-Regeneration und H2-ProduktionDFG, 390540038, EXC 2008: UniSysCatTU Berlin, Open-Access-Mittel - 202

Synthesis of N-heterocycles from diamines via H2-driven NADPH recycling in the presence of O2

Herein, we report an enzymatic cascade involving an oxidase, an imine reductase and a hydrogenase for the H2-driven synthesis of N-heterocycles. Variants of putrescine oxidase from Rhodococcus erythropolis with improved activity were identified. Substituted pyrrolidines and piperidines were obtained with up to 97% product formation in a one-pot reaction directly from the corresponding diamine substrates. The formation of up to 93% ee gave insights into the specificity and selectivity of the putrescine oxidase.DFG, 53182490, EXC 314: Unifying Concepts in CatalysisDFG, 284111627, H2-basierende Kaskaden für die Biosynthese von N-HeterocyclenTU Berlin, Open-Access-Mittel - 201

A dynamical comparison between iterative methods with memory: Are the derivatives good for the memory?

[EN] The role of the derivatives at the iterative expression of methods with memory for solving nonlinear equations is analyzed in this manuscript. To get this aim, a known class of methods without memory is transformed into different families involving or not derivatives with an only accelerating parameter, then they are defined as discrete dynamical systems and the stability of the fixed points of their rational operators on quadratic polynomials are studied by means of real multidimensional dynamical tools, showing in all cases similar results. Finally, a different approach holding the derivatives, and by using different accelerating parameters, in the iterative methods involved present the most stable results, showing that the role of the appropriated accelerating factors is the most relevant fact in the design of this kind of iterative methods.

A Study of the Factors Affecting Universiti Tun Hussein Onn Malaysia Students’ Entrepreneurial Intention

Unemployment is an issue in most of the countries, both developing and developed. Students spend their available life, money, and efforts in education for getting a good job. However, when they finish their education, they spend much time looking for a job and sometimes stay unemployed. It is believed that one of the best solutions for this problem is to start a privet business. Thus, this study embarked to study the factors that affect UTHM students’ entrepreneur intention. It followed the quantitative method and collected the data via online and hard questionnaires. The data then was analyzed using the Statistical Package for Social Science (SPSS) version 22.0. Four main variables were studied in this research namely, attitude, perceived behavior control, need for achievement, and family background. The findings of this study showed that all the variables were correlated with entrepreneurial intention. Moreover, the study also showed that all factors have a significant impact on entrepreneurial intention, except for the family background which was found to have no significant impact

An engineered escherichia coli strain with synthetic metabolism for in‐cell production of translationally active methionine derivatives

In the last decades, it has become clear that the canonical amino acid repertoire codified by the universal genetic code is not up to the needs of emerging biotechnologies. For this reason, extensive genetic code re‐engineering is essential to expand the scope of ribosomal protein translation, leading to reprogrammed microbial cells equipped with an alternative biochemical alphabet to be exploited as potential factories for biotechnological purposes. The prerequisite for this to happen is a continuous intracellular supply of noncanonical amino acids through synthetic metabolism from simple and cheap precursors. We have engineered an Escherichia coli bacterial system that fulfills these requirements through reconfiguration of the methionine biosynthetic pathway and the introduction of an exogenous direct trans‐sulfuration pathway. Our metabolic scheme operates in vivo, rescuing intermediates from core cell metabolism and combining them with small bio‐orthogonal compounds. Our reprogrammed E. coli strain is capable of the in‐cell production of L‐azidohomoalanine, which is directly incorporated into proteins in response to methionine codons. We thereby constructed a prototype suitable for economic, versatile, green sustainable chemistry, pushing towards enzyme chemistry and biotechnology‐based production

The concept of the entrepreneurial ecosystem refers to the interaction between the various stakeholders of institutions and individuals to encourage implementation towards entrepreneurship, innovation and the growth of Small and Medium Enterprises (SMEs). Universities play an important role in the entrepreneurial ecosystem for entrepreneurship and forms a catalyst for economic growth and capacity building to enhance the innovation, creativity and competitiveness of a country. The objective of this study was to explore the involvement of UTHM students in entrepreneurial activities based on the university’s entrepreneurial ecosystem in terms of financial assistance, infrastructure, education and training. The methodology employed for this study is a qualitative inquiry by using in-depth interview technique. The respondents consisted of 10 students and officers from the Centre of Business Entrepreneurship Development. The data were then being transcribed and analysed using thematic analysis. The results of this study showed that financial assistance, infrastructure, education and training is a very important ecosystem in increasing student involvement in entrepreneurship. The study also shows that there are inadequate infrastructure facilities to meet the demand of students for business. The lack of provision of loans also affected the level of student participation in entrepreneurship at the University

Neurotoxicity and neuroprotective effects of Polyimides (PI) and Polyphenylenevinylene (PPV) against Hydrogen Peroxide (H2O2) / Norfaezah Mazalan ... [et al.]

Recently, research and development in the field of drug delivery systems (DDS) facilitating site-specific therapy has reached significant progression. DDS based on polymer micelles, coated micro- and nanoparticles, and various prodrug systems including water-soluble polymer have been prepared and extensively studied as novel drugs designed for cancer chemotherapy and brain delivery. Since polymers are going to be used in human, this study has the interest of testing two types of polymer, polyimides (PI) and polyphenylenevinylene (PPV) on neuronal cells. The objective of this study was to determine the possible neurotoxicity and potential neuroprotective effects of PI and PPV towards SH-SY5Y neuronal cells challenged by hydrogen peroxide (H2O2) as an oxidant. Cells were pretreated with either PI or PPV for 1 hour followed by incubation for 24 hour with 100 μM of H2O2. MTS assay was used to assess cell viability. Results show that PI and PPV are not harmful within the concentration up to 10 μM and 100 μM, respectively. However, PI and PPV do not protect neuronal cells against toxicity induced by H2O2 or further up the cell death
