An unstructured growth model for the recombinant methylotrophic yeast P. pastoris Mut(+) expressing the heavy-chain fragment C of botulinum neurotoxin serotype A [BoNT/A(H(c))], was successfully established in quasi-steady state fed-batch fermentations with varying cell densities. The model describes the relationships between specific growth rate and methanol concentration, and the relationship...

epidemics of methanol poisoning happen across the globe. there are prognostic factors associated with morbidity or mortality from methanol poisoning. recently we have compared retrospective observational case series of methanol-poisoned patients from norway (1979 and 2002-2005), estonia (2001) and tunisia (2003/2004), and patients from two different centers in iran (teheran 2004-2009 and mashha...

introduction methanol is a highly toxic substance and methanol poisoning results in severe health situations. methanol poisoning occurs when it is consumed by various methods such as orally, by inhalation, and transdermally. transdermal poisoning is rarely seen and causes severe health complications. conclusions methanol poisoning presents to the emergency department in our country with many di...

INTRODUCTION In an effort to improve air quality and decrease dependence on petroleum, the federal government, industry, and other groups have encouraged development of alternative fuels such as methanol to substitute for gasoline or diesel fuel. Methanol is also a candidate to provide the hydrogen for fuel cells, which are being developed for a variety of power sources (including motor vehicle...

abstract background: herbal distillates have been used for many centuries as drinks, flavors, and herbal medicine in iran, especially in the city of urmia. recently, some studies claimed the presence of methanol in different types of herbal distillates. methanol is a highly toxic compound which can cause acute or chronic toxicity in humans. acute poisoning with methanol can cause different comp...

background & aim: stroke in young adults is rare but can be devastating for the affected individuals and their families. some triggers of stroke may be acute but transient effects on the pathophysiological condition while other factors may be effective overa longer period. methods & materials: this study was a case-crossover study on 18 young adults. the study included patients aged 15-49 years...

The use of alcohol blends in direct alcohol fuel cells may be a more environmentally friendly and less toxic alternative to the use of methanol alone in direct methanol fuel cells. This paper assesses the behaviour of a direct methanol fuel cell fed with aqueous methanol, aqueous ethanol and aqueous methanol/ethanol blends in a long term experimental study followed by modelling of polarization ...

We calculate the eigenspectrum of random walks on the Eden tree in two and three dimensions. From this, we calculate the spectral dimension ds and the walk dimension dw and test the scaling relation ds = 2df/dw (= 2d/dw for an Eden tree). Finite-size induced crossovers are observed, whereby the system crosses over from a short-time regime where this relation is violated (particularly in two dim...
