• mechanism
  • His studies on the physiological background of the mechanism of flowering of higher plants revealed some interaction between the role of vernalisation (mainly cold treatment) and the direct effect of the plant hormone Gibberellic acid. (wikipedia.org)
  • Authors review the previous pathogenic theories, discuss the link between concentric sclerosis and Liesegang's periodic precipitation phenomenon and propose a new mechanism based on self-organization. (wikipedia.org)

  • changes
  • These rapidly alternating fields induce electrical currents within localized, targeted regions of the cortex which are associated with various physiological and functional brain changes. (jove.com)
  • Parasite progeny sequentially infect one or more intermediate hosts, inside which they may undergo asexual reproduction and physiological changes. (wikipedia.org)
  • novel
  • As an example, we chose the HA and NA proteins expressed by the novel H7N9 virus that recently emerged in China. (jove.com)
  • To address these challenges, we have previously developed and validated a pan-viral microarray platform called the Virochip with the capacity to detect all known viruses as well as novel variants on the basis of conserved sequence homology 1 . (jove.com)
  • The Virochip has also been used to identify novel viruses, including the SARS coronavirus 6,7 , a novel rhinovirus clade 5 , XMRV (a retrovirus linked to prostate cancer) 8 , avian bornavirus (the cause of a wasting disease in parrots) 9 , and a novel cardiovirus in children with respiratory and diarrheal illness 10 .

  • This manuscript will describe this chronic social stress paradigm using repeated exposure of a lactating dam to a novel male intruder, and the assessment of the behavioral, physiological, and neuroendocrine effects of this model. (jove.com)
  • infections
  • Using the Virochip, we have identified the full spectrum of viruses associated with respiratory infections, including cases of unexplained critical illness in hospitalized patients, with a sensitivity equivalent to or superior to conventional clinical testing 2-5 . (jove.com)
  • The effectiveness of this protocol was first evaluated with 1,762 coupled serum/DBS pairs for detecting markers of hepatitis B virus, hepatitis C virus, and human immunodeficiency virus infections on an automated analytical platform. (jove.com)
  • viral
  • Although here we focus on influenza virus surface glycoproteins, this method can also be used to produce other viral and cellular surface proteins. (jove.com)
  • HCV in vitro research is therefore limited to human hepatoma cell lines permissive for virus entry and completion of the viral life cycle. (jove.com)
  • To assess the influence of dominant restrictions on the complete viral life cycle including cell entry, RNA translation, replication and virus assembly, we took advantage of a human liver cell line (Huh-7 Lunet N cells 9 ) which lacks endogenous expression of CD81, an essential entry factor of HCV.

  • However, a number of physiological and technical issues can affect the accuracy of the results and appropriate guidelines for the technique have been published. (jove.com)
  • However, many other biological definitions have been proposed, and there are some borderline cases of life, such as viruses. (wikipedia.org)
  • proteins
  • Working with the components of mutants of the tobacco mosaic virus (TMV) he analysed the behaviour of their coat proteins. (wikipedia.org)
  • According with Dr. Lucchinetti investigations, in Balo's concentric sclerosis, the rings may be caused by a physiological hypoxia (similar to that caused by some toxins or viruses) in the lesion, which is in turn countered by expression of stress proteins at the border. (wikipedia.org)
