Stool samples were obtained from eight different hospitals in Peninsular Malaysia. Out of 168 stool samples examined, 45.8% were from children less than 5 years old and 22% were antigen positive. Due to small amount of fecal material left from this age bracket, NoV was not screened since it is already known that 90% in this age group are often infected with rotavirus (RV), which is the most common cause of severe diarrhoea in children.
From the remaining total screened, only 89% were screened for NoV and 9.3% were NoV genogroup II. By phylogenetic analysis, GII/3 and GII/4 were found to be the prevalent strains. Majority of these samples were closely related to GII/4 Nagano 2007/JP strains from Japan and one was closely related to GII/4 from Bristol, UK.
This study also provides valuable information on NoV genotype , which could be used for surveillance and vaccine strategy. The presence of both GII.4 and GII.3 are in concordance to other strains reported elsewhere in the world. This novel GII.4 variant, termed Hunter virus (Bull et al., 2006) have been identified as the etiological agent in 18 outbreaks investigated including The Netherlands, Japan and Taiwan in 2004 and 2005.This study is the first report of NoV in lettuces in Malaysia. This preliminary study should be continued since NoV is now being identified as one of the common cause of diarrhea and is still under reported in Malaysia.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...

In an article that appears in the journal “Review of Modern Physics”, researchers at the Laboratory for Attosecond Physics (LAP) assess the current state of the field of ultrafast physics and consider its implications for future technologies.
Physicists can now control light in both time and space with hitherto unimagined precision. This is particularly true for the ability to generate ultrashort...
