Background: Tuberculosis (TB) is one of the most significant health-care problems worldwide. The host’s genetics play an important role in the development of TB in humans. The disease progresses through several stages, each of which can be under the control of different genes. The precise genes influencing the different stages of the disease are not yet identified. The aim of the current study ...

We define a simple, explicit map sending a morphism f : M → N of pointwise finite dimensional persistence modules to a matching between the barcodes of M and N . Our main result is that, in a precise sense, the quality of this matching is tightly controlled by the lengths of the longest intervals in the barcodes of ker f and coker f . As an immediate corollary, we obtain a new proof of the alge...

Polyadenylation of RNA molecules in bacteria and chloroplasts has been implicated as part of the RNA degradation pathway. The polyadenylation reaction is performed in Escherichia coli mainly by the enzyme poly(A) polymerase I (PAP I). In order to understand the molecular mechanism of RNA poly-adenylation in bacteria, we characterized the biochemical properties of this reaction in vitro using th...

We have labeled the nucleoside triphosphate-binding domain of Escherichia coli rho factor with the ATP affinity analog [3H]pyridoxal 5'-diphospho-5'-adenosine (PLP-AMP). PLP-AMP completely inactivates the RNA-dependent ATPase activity of rho upon incorporation of 3 mol of reagent/mol of hexameric rho protein. Although the potency of PLP-AMP is enhanced when an RNA substrate such as poly(C) is p...

Cancer is a multifactorial disease that continues to increase. Lignans are known be important anticancer agents. However, due the structural diversity of lignans, it difficult associate activity with particular subclass. Therefore, present study sought evaluate association lignan subclasses antitumor activity, considering genetic profile variants selected targets. To do so, predictive models we...

There are many instances in genomics data analyses where measurements are made on a multivariate response. For example, alternative splicing can lead to multiple expressed isoforms from the same primary transcript. There are situations where differences (e.g. between normal and disease state) in the relative ratio of expressed isoforms may have significant phenotypic consequences or lead to pro...

Background and Aims: Ficolins are proteins that bind to carbohydrates, act as opsonins and play an important role in innate immunity. Polymorphism in ficolin-3 gene (FCN3) can lead to complement deficiency and increase the risk of some disorders such as diabetes. The aim of this study was to investigate the frequency of FCN3+1637delC as a single nucleotide polymorphism in this gene in healthy a...

A solid-state nanopore platform with a low noise level and sufficient sensitivity to discriminate single-strand DNA (ssDNA) homopolymers of poly-A40 and poly-T40 using ionic current blockade sensing is proposed and demonstrated. The key features of this platform are (a) highly insulating dielectric substrates that are used to mitigate the effect of parasitic capacitance elements, which decrease...
