Species invasion will cause certain harm to the local ecosystem. Vespa mandarinia
, discovered on Vancouver Island, is harmful to agriculture and predators of European honeybees. The government tried to use a crowdsourcing system to collect information and formulate policies to eliminate Vespa mandarinia
. However, the information provided by the local population about Vespa mandarinia
is not entirely accurate. For this problem, we build a method to mine trusted informat...

This paper aims to clarify the current research status and hot spots, as well as to predict future research trends about radical S-adenosyl-methionine (SAM) enzymes. We conducted this study based on 649 research papers about radical SAM enzymes published in the years of 1999 to 2020 on the Web of Science. Tools like CiteSpace were employed for statistical and visual network analysis of the time of publication, national cooperative relations, core authors, and co-word networks. Our findings inclu...

An important feature of blockchain technology is that all participants jointly maintain transaction data and can achieve mutual trust relationships without integrated control, which relies on distributed consensus algorithms. Practical Byzantine Fault Tolerant algorithm (PBFT) is a fault-tolerant algorithm based on state machine replication, which solves the Byzantine error, that is, the malicious behavior of nodes. In PBFT, all participating nodes are divided into the primary node and backup no...

Human cancer, which has complex pathogenesis, is generally relative to the dysfunction of biological systems. Thus, our research is not at molecular level, but at system level, i.e. molecular network. In this paper, specially, we use PPI network. In order to construct a PPI network, we used the SSN method which is proposed by Professor X. Liu and others. The SSN method is distinct from the traditional network methods, especially in screening differential expressed genes. Besides, the traditional...

In silico analysis can be useful to infer about the
horizontal gene transfer (HGT) as well as to deduce about the evolutionary
relations of catabolic genes. In this study, we performed the analysis of two
housekeeping genes (fabD and rpoD) and two catabolic gene

The imbalance between oxidant molecules and
antioxidant agents is characterized as oxidative stress (OS) and may lead to
severe damage to the organism. In contrast, the physical training of aerobic
and resistive character promotes increases of the antioxidant response,
resulting in a balance and/or minimizing damage. Therefore, the objective of
the study is to verify the effect of aerobic training, resistive training and

Genetic epidemiological studies have suggested that several genetic
variants increase the risk for hypertension.
It is likely that a number of genes rather than a single gene account for
the heritability of this complex disorder. However, the genetic analysis of
hypertension produced complex, inconsistent
and nonreproducible results, which makes it difficult to draw conclusions
about the association between specific genes

Motif discovery is one of the fundamental problems that have important applications
in identifying drug targets and regulatory sites. Regulatory sites on DNA
sequence normally correspond to shared conservative sequence patterns among the
regulatory regions of correlated genes. These conserved sequence patterns are
called motifs. Identifying motifs and corresponding instances is very
important, so biologists can investigate the interactions between DNA and
proteins, gene regulation, cell developm...

The Wisconsin Breast Cancer Dataset has been heavily cited as a benchmark dataset for classification. Neural Network techniques such as Neural Networks, Probabilistic Neural Networks, and Regression Neural Networks have been shown to perform very well on this dataset. However, despite its obvious practical importance and implications for cancer research, a thorough investigation of all modern classification techniques on this dataset remains to be done. In this paper we examine the efficacy of c...

In this study, the chromosome karyotype of Plumbago auriculata was analyzed by using a chro-mosome mounting technique with the primary root tip of seed germination. The aim was to find out the most suitable method for Plumbago auriculata by comparing the effect of different pretreatment and dissociation time on chromosome. The results showed that the best pretreatment was 0.05% colchicine solution under 0℃ - 4℃ or 2 h and then 1 mol/L HCL under 60℃ water for 6 min. Karyotype analysis of Plumbago...
