NRTIs’ effect on the sequence of mitochondrial DNA HV 2 in HIV infected patients

Ya-Song WU MD, PhD, Xin-Yue CHEN MD, Ying SHI PhD, Hao WU MD, De-Xi CHEN MD, PhD, Yu SUN MD, Fu-Jie ZHANG

Frontiers of Medicine 2010, Volume 4, Issue 2,   Pages 177-184 doi: 10.1007/s11684-010-0038-1

Abstract: Potent combination antiretroviral therapy (cART) has significantly improved the life expectancy of people living with human immunodeficiency virus (HIV), but it has many side effects such as lipodystrophy (LD), hepatic steatosis, and lactic acidosis. Nucleoside reverse transcriptase inhibitors (NRTIs) could damage the mitochondria by inhibiting the human DNA polymerase gamma, leading to mtDNA deletion. However, it remains uncertain whether NRTIs could induce the hypervariable region (HV) mutations of the D loop of mitochondria in Chinese HIV/AIDS patients, and whether that effect is different between individuals with and without LD. Hereby, 30 Chinese AIDS patients who were receiving antiretroviral drugs were recruited, among which 16 had symptomatic LD and 14 did not. Blood samples were collected prior to and after 96 weeks of treatment. Total DNA was extracted from peripheral blood mononuclear cells (PBMCs). Fragments of 728 bp in length containing HV 2 were amplified by standard polymerase chain reaction (PCR). Direct DNA-sequencing analysis techniques were used to detect mitochondrial sequence variants between paired longitudinal samples. Alterations were compared with the revised Cambridge Reference Sequence (rCRS) to determine mutation or polymorphism. Results showed that two years after ART, totally seven cases exhibited sequence variations, five individuals showed 73€A→G revised variation (two with and three without LD), while two cases of LD were found to have other nucleotide alterations. There was no new alteration in individuals without LD. In conclusion, NRTIs could induce mutation of mtDNA HV 2, which might contribute to the development of LD.

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 11,   Pages 1578-1586 doi: 10.1631/FITEE.1800458

Abstract: based on cryptography is a new paradigm in the field of nanotechnology. The overall performance of QCA is high compared to traditional complementary metal-oxide semiconductor (CMOS) technology. To achieve data security during nanocommunication, a cryptography-based application is proposed. The devised circuit encrypts the input data and passes it to an output channel through a cum data path selector, where the data is decrypted back to its original form. The results along with theoretical implication prove the accuracy of the circuit. Power dissipation and circuit complexity of the circuit have been analyzed.

Frontiers of Mechanical Engineering 2006, Volume 1, Issue 1,   Pages 111-114 doi: 10.1007/s11465-005-0013-8

Abstract:

A new microelectromagnetic relay is presented and fabricated based on micromachining technology, aiming at the miniaturization and high manufacturing efficiency of electromagnetic relays. This microrelay is composed of a lower magnetic circuit, a planar exciting coil, and an upper magnetic armature. A complete magnetic circuit is composed, and the ON and OFF states are controlled by the current of the exciting coil. The dimension of this microrelay is 5 mm ? 5 mm ? 0.4 mm. The fabrication process mainly includes lithography, sputtering, electroplating, etching, sacrifice-layer technology, etc. Electromagnetic force is calculated theoretically. The calculation results are used for the optimization design of the armature and the number of turns of the exciting coil. A microelectromagnetic relay is fabricated and the initial test results are given. The resistance of the exciting coil is about 300 Ω. The switch-on state resistance is about 1.7 Ω at an exciting current of about 50 mA.

Crop residues: applications of lignocellulosic biomass in the context of a biorefinery

Maria Carolina ANDRADE, Caio de Oliveira GORGULHO SILVA, Leonora Rios de SOUZA MOREIRA, Edivaldo Ximenes

Frontiers in Energy 2022, Volume 16, Issue 2,   Pages 224-245 doi: 10.1007/s11708-021-0730-7

Abstract: Interest in lignocellulosic biomass conversion technologies has increased recently because of their potential to reduce the dependency on non-renewable feedstocks. Residues from a variety of crops are the major source of lignocellulose, which is being produced in increasingly large quantities worldwide. The commercial exploitation of crop residues as feedstocks for biorefineries which could be used to produce a variety of goods such as biofuels, biochemicals, bioplastics, and enzymes is an attractive approach not only for adding value to residues but also for providing renewable products required by the expanding bioeconomy market. Moreover, the implementation of biorefineries in different regions has the potential to add value to the specific crop residues produced in the region. In this review, several aspects of crop residue application in biorefineries are discussed, including the role of crop residues in the bioeconomy and circular economy concepts, the main technical aspects of crop residue conversion in biorefineries, the main crop residues generated in different regions of the world and their availability, the potential value-added bioproducts that can be extracted or produced from each crop residue, and the major advantages and challenges associated with crop residue utilization in biorefineries. Despite their potential, most biomass refining technologies are not sufficiently advanced or financially viable. Several technical obstacles, especially with regard to crop residue collection, handling, and pre-treatment, prevent the implementation of biorefineries on a commercial scale. Further research is needed to resolve these scale-up-related challenges. Increased governmental incentives and bioeconomic strategies are expected to boost the biorefinery market and the cost competitiveness of biorefinery products.

Abstract: Carbon capture and storage (CCS) have acquired an increasing importance in the debate on global warming as a mean to decrease the environmental impact of energy conversion technologies, by capturing the CO produced from the use of fossil fuels in electricity generation and industrial processes. In this respect, post-combustion systems have received great attention as a possible near-term CO capture technology that can be retrofitted to existing power plants. This capture technology is, however, energy-intensive and results in large equipment sizes because of the large volumes of the flue gas to be treated. To cope with the demerits of other CCS technologies, the chemical looping combustion (CLC) process has been recently considered as a solution for CO separation. It is typically referred to as a technology without energy penalty. Indeed, in CLC the fuel and the combustion air are never mixed and the gases from the oxidation of the fuel (i.e., CO and H O) leave the system as a separate stream and can be separated by condensation of H O without any loss of energy. The key issue for the CLC process is to find a suitable oxygen carrier, which provides the fuel with the activated oxygen needed for combustion. The aim of this work is to explore the feasibility of using perovskites as oxygen carriers in CLC and to consider the possible advantages with respect to the scrubbing process with amines, a mature post-combustion technology for CO separation.
