Article Synopsis
  • Paramyxoviruses like mumps virus, Newcastle disease virus, and Sendai virus are important pathogens, but not much is known about the host factors that help them infect cells.
  • A study using CRISPR technology discovered that two genes, CST and UGT, are crucial for these viruses to infect cells, as knocking them out results in reduced viral binding.
  • The UGT gene specifically aids in virus-cell fusion during Sendai virus entry and helps form larger syncytia (cell clusters) during mumps virus infection, indicating it plays a role in how these viruses spread between cells.

The serum neutralization (SN) test has been regarded as the "gold standard" for seroconversion following foot-and-mouth disease virus (FMDV) vaccination, although a high-level biosafety laboratory is necessary. ELISA is one alternative, and its format is constantly being improved. For instance, standard polyclonal antisera have been replaced by monoclonal antibodies (MAbs) for catching and detecting antibodies, and inactive viruses have been replaced by virus-like particles (VLPs).

Positive-stranded RNA viruses modify host organelles to form replication organelles (ROs) for their own replication. The enteroviral 3A protein has been demonstrated to be highly associated with the COPI pathway, in which factors operate on the ER-to-Golgi intermediate and the Golgi. However, Sar1, a COPII factor exerting coordinated action at endoplasmic reticulum (ER) exit sites rather than COPI factors, is required for the replication of foot-and-mouth disease virus (FMDV).

In the case of serotype O foot-and-mouth disease virus (FMDV), antibodies against five neutralizing sites play a pivotal role in protection of animals, with site 1 being considered the most crucial. However, recent studies indicated that the antibodies of vaccinated farm animals are mainly against site 2 rather than site 1. In Taiwan, blanket vaccination had been implemented for more than fifteen years, in which the porcinophilic isolate O/Penghu/2012 showed significant amino acid alterations in site 2 compared to the early isolate O/TW/97.

Studies related to healthcare ICT integration in Malaysia are relatively little, thus this paper provide a literature review of the integration of information and communication technologies (ICT) in the healthcare sector in Malaysia through the hospital information system (HIS). Our study emphasized on secondary data to investigate the factors related to ICT integration in healthcare through HIS. Therefore this paper aimed to gather an in depth understanding of issues related to HIS adoption, and contributing in fostering HIS adoption in Malaysia and other countries.
