Aria Seo, Junho Jeong, Yeichang Kim
As the sharing economic market grows, the number of users is also increasing but many problems arise in terms of reliability between providers and users in the processing of services. The existing methods provide shared economic systems that judge the reliability of the provider from the viewpoint of the user. In this paper, we have developed a system for establishing mutual trust between providers and users in a shared economic environment to solve existing problems. In order to implement a system that can measure and control users' situation in a shared economic environment, we analyzed the necessary factors in a cyber physical system (CPS)...

Chao Li, Xin Chen, Fuyuan Zhang, Xingxing He, Guozhen Fang, Jifeng Liu, Shuo Wang
Glucose assay is of great scientific significance in clinical diagnostics and bioprocess monitoring and to design new glucose receptor is necessary for development of more sensitive, selective and robust glucose detection techniques. Herein, a series of cyclic peptides (CPs) glucose receptor were designed to mimic the binding sites of glucose binding protein (GBP) and CPs' sequence contained amino acid sites Asp, Asn, His, Asp, Arg, which constituted the first layer interactions of GBP. The properties of these CPs used as a glucose receptor or substitute for the GBP were studied by using quartz crystal microbalance (QCM) technique...

Release of cytoplasmic proteins into the supernatant occurs both in bacteria and eukaryotes. Because the underlying mechanism remains unclear, the excretion of cytoplasmic proteins (ECP) has been referred to as "non-classical protein secretion." We show that none of the known specific protein transport systems of Gram-positive bacteria are involved in ECP. However, the expression of the cationic and amphipathic α-type phenol-soluble modulins (PSMs), particularly of PSMα2, significantly increase ECP, while PSMβ peptides or δ-toxin have no effect on ECP...

Whether preceded by preeclampsia, or occuring without antecedent warning symptoms, eclamptic seizures usually occur in the antepartum period between 20 and 40 weeks of gestation or within a few hours to 2 days postpartum. We report the case of a patient with pre-eclampsia who developed seizures after more than 2 days of delivery. In view of late onset postpartum seizures and non-responsiveness to magnesium sulphate, she was further evaluated and diagnosed to have congenital perisylvian syndrome(CPS). In CPS, polymicrogyric cortex is distributed in variable extensions around the sylvian fissure i...

Heavy drinking in relationships is complex and we focus on an understudied sample of concerned partners (CPs) worried about their U.S. service member/veteran partner's drinking. We evaluated the link between CP drinking and their own mental health, and how CP drinking moderated the efficacy of a web-based intervention designed to address CPs' mental health and communication. CPs (N = 234) were randomly assigned to intervention or control and completed assessments at baseline and 5 months later. CP drinking was associated with greater CP depression, anxiety, and anger independent of partner drinking...

Tobacco mosaic virus (TMV) causes severe plant diseases worldwide; however, effective antiviral agents for controlling TMV infections are not available. This lack of effective antiviral agents is mainly due to the poor understanding of potential targets associated with TMV infections. During infection, the coat protein (CP), which is delivered by viral particles into susceptible host cells, provides protection for viral RNA. Here, we found that Ningnanmycin (NNM), a commercially used plant antibacterial agent, inhibits the assembly of the CP by directly binding several residues...

The Cyber Physical Systems (CPS) paradigm is based on the deployment of interconnected heterogeneous devices and systems, so interoperability is at the heart of any CPS architecture design. In this sense, the adoption of standard and generic data formats for data representation and communication, e.g., XML or JSON, effectively addresses the interoperability problem among heterogeneous systems. Nevertheless, the verbosity of those standard data formats usually demands system resources that might suppose an overload for the resource-constrained devices that are typically deployed in CPS...

According to previous studies, three double-stranded (ds) RNA molecules (dsRNA1, 2, and 3) detected in Japanese pear are transmitted to the next generation with high frequency through both ovules and pollen. Nucleotide sequence analysis of dsRNA1-encoding RNA-dependent RNA polymerase (RdRp) has suggested that these dsRNAs are related to a cryptovirus named Pyrus pyrifolia cryptic virus (PpCV). In this study, purified dsRNA prepared from a PpCV-infected Japanese pear cultivar was subjected to next-generation deep sequencing...

Current methodologies for the assessment of urea cycle (UC) enzymatic activity are insufficient to accurately evaluate this pathway in biological specimens where lower UC is expected. Liver cell lines, including HepaRG, have been described to have limited nitrogen fixation through the UC, limiting their applicability as biocomponents for Bioartificial Livers (BAL). This work aims to develop novel and sensitive analytical solutions using Mass Spectrometry-based methodology to measure the activity of four UC enzymes in human liver and HepaRG cells...
