New bird flu strain requires vigilance researchers warn

Conclusion This is important research tracking the origins of the new H7N9 bird flu virus, which gives some clues about how it might behave in the future. Scientists are particularly concerned that a future mutation could mean it is transmitted between humans, which increases the risk of a pandemic (an epidemic of infection across countries or continents). For travellers to China and other countries affected by bird flu, it's important to observe the following precautions: avoid visiting live animal markets and poultry farms avoid contact with surfaces that are contaminated with animal faeces don't eat or handle undercooked or raw poultry, egg or duck dishes don't pick up or touch dead or dying birds always follow good personal hygiene practices, including washing your hands regularly Read more about reducing your risk of bird flu when travelling in affected countries.

Authors: Cui T, Li Z, Zhou Q, Li W Abstract Diploidy is the typical genomic mode in all mammals. Haploid stem cells are artificial cell lines experimentally derived in vitro in the form of different types of stem cells, which combine the characteristics of haploidy with a broad developmental potential and open the possibility to uncover biological mysteries at a genomic scale. To date, a multitude of haploid stem cell types from mouse, rat, monkey and humans have been derived, as more are in development. They have been applied in high-throughput genetic screens and mammalian assisted reproduction. Here, we review t...

With support from a transcriptome profile of the same mES cell line, we arrived at an integrated dataset of 9,370 protein expressions that may be useful to understand the stem cell dynamics. 6,278 protein identificati...

GachonAbstractChytrids have long been recognised as important parasites of microalgae in freshwater systems, able to shape the dynamics of blooms, the gene pool of their host and phytoplankton succession. In the sea however, where the presence of these organisms is erratic and ephemeral, studies concerning chytrids are sparse and confined to metabarcoding surveys or microscopy observations. Despite the scarcity of data, chytrid epi...

This study was carried out to evaluate embryotoxicity of CR decoction in vivo and in vitro, and to explore the mechanism of embryotoxicity from the perspective of bone metabolism.Materials and methodsIn animal experiments, pregnant mice were randomly assigned into 5 groups, i.e. mice were orally treated with CR decoction at dosages of 0 (distilled water, as negative controls), 2, 8, 32 g/kg/d (low, medium and high-dose group), and vitamin A (as positive controls), respectively. Maternal and embryo-fetal parameters were registered after cesarean section. The fetal skeletal development was further assessed with the alizari...

We refer transmission of infections in India which have implications for Pakistan [1]. As compared to Pakistan, the range and burden of infectious diseases are enormous in India including Severe Acute Respiratory Syndrome (SARS) contagion in 2002 –2003, Influenza A virus epidemic of 2006 (avian influenza), 2007 Equine influenza, Swine flu pandemic outbreaks in 2009 and 2014 [2]. Moreover, episodes of infectious diseases continue to rise in India, with a recent surge of chikungunya and dengue cases in 2016 [1].

Conclusion This modelling study shows how the strains of influenza A – "bird flu" – circulating when a person is born give them lifelong protection against new subtypes with the same H protein groups. The researchers call this immune imprinting. This may help to explain the high severity and mortality rate seen among certain groups. For example, the massive flu pandemic of 1918 was an H1N1 strain. This had a very high fatality rate among young adults, which the researchers consider may have been because when they were born (between 1880 and 1900), H3 was the dominant strain. Therefore they had no prot...

The Zika virus attracted many headlines this winter, but a recent admission by the chief medical officer at a leading vaccine manufacturer -- that the world is ill-prepared to deal with pandemic outbreaks -- underscores a fundamental problem. To ensure safety and efficacy, the federal government's regulatory approval process for new vaccines may extend development timelines for years. So when The New York Times reports that "eighteen organizations are working on developing a vaccine for the Zika virus," it is likely that those companies will labor for a very long time. Vaccinations rightly require stri...

INTRODUCTION According to the Center for Research on the Epidemiology of Disasters (CRED), natural disasters are classified as geophysical, metrological, hydrological, climatological and biological. These five disaster types encompass 12 disaster types and more than 30 sub-types. The 20th Century witnessed an increase in disaster losses, and this has continued its upward trend in the current Century. Climate change will increase the rate of increase of disasters, particularly those of meteorological origin. This is reflected in the fact that, of all natural hazards, floods are the most frequent and their impacts are also i...
