This paper describes a new readout integrated circuit and non-uniformity correction (NUC) method that ensures the bolometer array has low over wide operating temperature range without thermoelectric cooler (TEC). The proposed NUC minimizes memory required for signal processing, making it suitable compact power-efficient portable infrared cameras. It corrects aging phenomenon through start-up ca...

Staphylococcus aureus is a prominent bacterial pathogen that causes a diverse range of acute and chronic infections. Recently, it has been demonstrated that the secreted nuclease (Nuc) enzyme is a virulence factor in multiple models of infection, and in vivo expression of nuc has facilitated the development of an infection imaging approach based on Nuc-activatable probes. Interestingly, S. aure...

A thorough analysis of low convergence speed and ghosting artifacts in temporal high-pass filter correction has been undertaken in this paper and it has found out that the keys of these problems are the interference of a large sum of unrelated scene information in the nonuniformity correction (NUC) process. In order to overcome these drawbacks, a new scene-based NUC technique based on bilateral...

This paper presents an infrared focal plane array (IRFPA) response nonuniformity correction (NUC) algorithm which is easy to implement by hardware. The proposed NUC algorithm is based on the linear correction scheme with the useful method of pixel offset correction coefficients update. The new approach to IRFPA response nonuniformity correction consists in the use of pixel response change deter...

We investigated the scintillation properties of nonuniformly correlated (NUC) beams in atmospheric turbulence and have shown that NUC beams can not only have lower scintillation but also higher intensity than Gaussian-Schell model beams and even higher intensity than coherent Gaussian beams over certain propagation distances.

Current therapies of chronic hepatitis B (CHB) remain limited to pegylated-interferon-alpha (PegIFN-α) or any of the five approved nucleos(t)ide analogues (NUC) treatments. While viral suppression can be achieved in the majority of patients with the high-barrier-to-resistance new-generation of NUC, i.e. entecavir and tenofovir, HBsAg loss is achieved by PegIFN-α and/or NUC in only 10% of patien...

The inducible cyclooxygenase isoform (COX-2) is associated with inflammation, tumorigenesis, as well as with physiological events. Despite efforts deployed in order to understand the biology of this multi-faceted enzyme, much remains to be understood. Nucleobindin (Nuc), a ubiquitous Ca(2+)-binding protein, possesses a putative COX-binding domain. In this study, we investigated its expression a...

Lactococcus lactis, a gram-positive organism widely used in the food industry, is a potential candidate for the secretion of biologically useful proteins. We examined the secretion efficiency and capacity of L. lactis by using the Staphylococcus aureus nuclease (Nuc) as a heterologous model protein. When expressed in L. lactis from an efficient lactococcal promoter and its native signal peptide...

Two different real-time quantitative PCR (RTQ-PCR) approaches were applied for PCR-based quantification of Staphylococcus aureus cells by targeting the thermonuclease (nuc) gene. Purified DNA extracts from pure cultures of S. aureus were quantified in a LightCycler system using SYBR Green I. Quantification proved to be less sensitive (60 nuc gene copies/microl) than using a fluorigenic TaqMan p...

Medication adherence is important for the success of nucleos(t)ide analogue (NUC) treatment for chronic hepatitis B. The aims of this study were to determine adherence to NUCs and factors associated with NUC adherence and to correlate NUC adherence with the occurrence of virological breakthroughs in patients with chronic hepatitis B. Consecutive patients with chronic hepatitis B receiving NUC w...
