We present a new wide-field map of the radio galaxy 3C 129 and its companion galaxy 3C 129.1 at λ = 90 cm. We see a distinct steep-spectrum feature near the head of 3C 129, extending in a direction perpendicular to the radio tails. We propose that this Crosspiece might consist of fossil radio plasma, which has been re-energized by the compression of the bow shock of the supersonically moving ga...

Human enterovirus type 71 (EV71), the major causative agent of hand-foot-and-mouth disease, has been known to cause fatal neurological complications. Unfortunately, the reason for neurological complications that have been seen in fatal cases of the disease and the relationship between EV71 virulence and viral genetic sequences remains largely undefined. The 3C protease (3Cpro) of EV71 plays an ...

Different sublimation growth conditions of 3C-SiC approaching a bulk process have been investigated with the focus on appearance of macrodefects. The growth rate of 3C-SiC crystals grown on 6H-SiC varied from 380 to 460 μm/h with the thickness of the crystals from 190 to 230 μm, respectively. The formation of macrodefects with void character was revealed at the early stage of 3C-SiC crystal gro...

We report the molecular investigations of a large influenza A(H3N2) outbreak, in a season characterised by sharp increase in influenza admissions since December 2016. Analysis of haemagglutinin (HA) sequences demonstrated co-circulation of multiple clades (3C.3a, 3C.2a and 3C.2a1). Most variants fell into a novel subclade (proposed as 3C.2a2); they possessed four unique amino acid substitutions...

Proteinase 3C of hepatitis A virus (HAV) plays a key role in the viral life cycle by generating mature viral proteins from the precursor polyprotein. In addition to its proteolytic activity, 3C binds to viral RNA, and thus influences viral genome replication. In order to investigate the interplay between proteolytic activity and RNA binding at the molecular level, we subjected HAV 3C and three ...

Hybrid nanotubes of carbon and halloysite nanotubes (HNTs) with different carbon:HNTs ratio were hydrothermally synthesized from natural halloysite and sucrose. The samples display uniformly cylindrical hollow tubular structure with different morphologies. These hybrid nanotubes were concluded to be promising medium for physisorption-based hydrogen storage. The hydrogen adsorption capacity of p...

The substrate recognition properties of the polio-virus type 1 and coxsackievirus B3 3C proteinases have been examined in vitro by allelic and suballelic exchange of 3C between the cloned virus genomes. The activity of the altered 3C proteinases was examined by translation of synthetic RNA in a rabbit reticulocyte lysate/HeLa cell extract translation system. Analysis of the subsequent processin...

Current advancement in electronic devices is so rapid that silicon, the semiconductor material most widely used today, needs to be replaced in some of the fields. Silicon carbide (SiC) is a wide band gap semiconductor satisfying requirements to replace silicon in devices operating at high power and high frequency at elevated temperature, and in harsh environments. Hexagonal polytypes of SiC, su...

Replication of picornaviral genomes requires recognition of at least three cis-acting replication elements: oriL, oriI, and oriR. Although these elements lack an obvious consensus sequence or structure, they are all recognized by the virus-encoded 3C protein. We have studied the poliovirus 3C-oriI interaction in order to begin to decipher the code of RNA recognition by picornaviral 3C proteins....
