Influenza A viruses are the causative agents of seasonal and pandemic infections. Influenza strains have recently emerged that show resistance to anti-viral drugs. Moreover, therapies in critically ill patients with severe influenza are limited, with the current anti-viral drugs showing disappointing results even in the absence of obvious viral resistance. Given the high mortality associated with avian H5N1 or H7N9 infections and the risk of pandemic potentials, effective drugs are needed for the treatment of severe influenza. A virus-host interaction is a multidimensional host response, in which not only genes and protein but also metabolites are up- or down-regulated, and cellular pathways and networks implicated in the viral pathogenesis are perturbed. Thus, it seems an attractive strategy to overcome influenza by targeting host metabolites and/or metabolic pathways involved in viral pathogenesis. Using lipidomics and lipid libraries screening, potectin D1 isomer (PDX) derived from the 15-lipoxygenase product 17S-H(p)DHA and/or 17HDHA precursor, has recently been identified, which suppresses influenza virus replication by inhibiting the nuclear export of viral mRNA rather than regulating resolution of inflammation. Contribution of the protectins to control influenza virus replication and their therapeutic potentials are reviewed here.

A spine immobilization tool that can control the movement of the spine with improved safety as a spine immobilization tool that includes a first covering portion, a second covering portion, and a joint portion. The first covering portion covers at least a part of a vertebral arch of a vertebra at a head-side among the adjacent vertebrae, and thus can be fixed to the vertebra. The second covering portion covers at least a part of a vertebral arch of a vertebra at a buttock side amongst the adjacent vertebrae, and thus can be fixed to the vertebra. The joint portion couples the first covering portion and the second covering portion together while allowing changing relative positions of the first covering portion and the second covering portion.


The objective of the present invention is to provide a method and a means of rapidly and reliably detecting lymph node metastasis in cancer or the risk of lymph node metastasis. Specifically, the present invention provides a method and a rapid determination kit for detecting lymph node metastasis in cancer or its risk by identifying a certain genetic polymorphism of the human CRP gene, and it is clinically significant in determining the treatment strategy, because effective prediction/determination can be made regarding lymph node metastasis, which is an important phenomenon in cancer progression.


The present invention provides: a method of producing, at low temperature, a magnetic recording medium comprising an L1_(0)FePt thin film which is highly (001)-oriented and highly L1_(0)-ordered; and a magnetic recording medium comprising an L1_(0)FePt thin film that can be obtained by this method. In the production method of a magnetic recording medium (10), a thin film formation step S1 of forming a thin film 2 containing an FePt alloy and an oxide of metal having a melting point of 100 C. or more and 500 C. or less is carried out; an annealing step S2 of annealing the thin film 2 to a predetermined temperature is carried out; thereby a magnetic recording layer 2 containing the FePt alloy having a L1_(0)-ordered structure and the oxide of metal is formed. The magnetic recording medium can be obtained by this production method.
