2020-12-15

In mammals, ribonucleotide reductase (RNR) is a unique enzyme that catalyzes the rate-limiting step of de novo synthesis of deoxyribonucleoside triphosphates (dNTPs).7, 8 Mammalian RNR consists of two homodimer subunits: the large catalytic dimer RRM1 and the small regulatory dimer RRM2 or RRM2B. An

Introduction Breast cancer is the most common malignant tumor in women and the second leading cause of female death [1]. In recent years, with the improvement of early detection and the emergence of new treatment methods, the mortality rate of breast cancer has been greatly reduced. However, the

We continued to investigate the contribution of the EP1 Ac-IETD-pNA to nociceptive sensitization by utilizing its natural ligand PGE and tested the effect of local subcutaneous injection of PGE (5nmol in 5μl) into one hindpaw on mechanical and heat pain thresholds. Wild-type mice displayed maximum

In conclusion, substrate enabled effective detection of L-alanylaminopeptidase activity in all Gram-negative bacteria tested here. The chromogenic substrate showed high sensitivity at a relatively low concentration (50 mgL), with no diffusion of the coloured chelate into the surrounding agar. Lack o

Another enzyme class that has emerged as a potential alternative to P450s are the so-called ‘unspecific peroxygenases’ (UPOs). They also contain a heme but are extracellularly expressed fungal enzymes that are often more stable than P450 monooxygenases. Importantly, UPOs use H2O2 instead of O2 as th

2020-12-15

Ageing is associated with increased reactive oxygen species (ROS) production, oxidative stress and oxidative damage [43,44]. Overproduction of ROS can impair endothelial function by suppressing NO synthesis and scavenging NO thereby decreasing its overall bioavailability. Moreover, sustained oxidati

Diagnosis of NCC can be accomplished via imaging techniques and serological confirmatory testing. The best immunodiagnostic test for NCC, the enzyme-linked immunotransfer blot EITB (Tsang et al., 1989), is based on the detection of Colistin Methanesulfonate sodium salt to one or more of the 7 lenti

During the entire life of individual, articular chondrocyte as well as subchondral bone receives acute or chronic stress. Joints homeostasis is maintained by biomechanical stress, as rapid loss of proteoglycan in joints occurs due to immobilization or disuse. These osteophytes are fibrocartilage cap

Discussion and conclusion Ubiquitination and deubiquitination have emerged as important mechanisms involved in p53 management. This review revealed that various DUBs can regulate p53 or p53-Mdm2-MdmX networks. Herein, we reviewed the current progress made toward elucidating the complexities in th

DAPK-1 is involved in the p53 dependent apoptotic pathway and it is a mediator of γ-interferon induced apoptosis. DAPK-1 is also involved in other death signaling pathways (tumor necrosis factor-α, CD95 and transforming growth factor-β) and it blocks tumor metastasis in vivo. The loss of DAPK mRNA M

Plants Cp are widely distributed in the plant kingdom and are believed to act as virulence/defense factors for both hosts and pathogens. Cp are also found in plants, animals and bacteria and are known to be virulence factors involved in bacterial pathogenicity [29]. Further, Cp are involved in pepti

In this study, a GMI of 1.0 was associated with high sensitivity above 90%, specificity below 30% and higher negative predictive value. However, this cut-off couldn't have been optimal because of the lower level of Youden J Index which was 50% of patients with culture positive sputum had a GMI >6.0.

There are two general approaches to building Bayesian networks for the purpose of risk assessment. Researchers can implement static models that predict risk or survival at a snap-shot of time. For example, Loghmanpour et al. [10] created Bayesian network-based risk assessment models for patient data
