Acerola's pectin methylesterase: studies of heat inactivation
(Elsevier B.V., 2000-12-01)
The effect of temperature on the activity of acerola's pectin methylesterase (PME) was studied to determine its heat-inactivation. The acerola's pectin methylesterase (PME; EC: 3.1.1.11) is very stable at 50 degrees C (10% ...
Independent clonal origin of multiple uterine leiomyomas that was determined by X chromosome inactivation and microsatellite analysis
(Mosby, Inc, 2005-10-01)
Objective: In an attempt to clarify the clonality and genetic relationships that are involved in the tumorigenesis of uterine leiomyomas, we used a total of 43 multiple leiomyomas from 14 patients and analyzed the allelic ...

Inactivation of vesicular stomatitis virus through inhibition of membrane fusion by chemical modification of the viral glycoprotein
(2007-01-01)
Membrane fusion is an essential step in the entry of enveloped viruses into their host cells triggered by conformational changes in viral glycoproteins. We have demonstrated previously that modification of vesicular ...
Thermal inactivation of Phytophthora nicotianae
(2000-01-01)
Phytophthora nicotianae was added to pasteurized soil at the rate of 500 laboratory-produced chlamydospores per gram of soil and exposed to temperatures ranging from 35 to 53°C for 20 days. The time required to reduce soil ...
Determination of amylase activity in cotyledons of Phaseolus vulgaris L. cv. carioca
(Brazilian Archives of Biology and Technology, 1998-06-01)
Determination of α- and β-amylase activity in the extracts of cotyledons of Phaseolus vulgaris L. cv. cariocawas done using selective inactivation of α-amylase by lowering the pH of the incubation medium or by the use of ...
Unusual X-Chromosome Inactivation Pattern in Patients with Xp11.23-p11.22 Duplication: Report and Review
(Wiley-Blackwell, 2016)
In females carrying structural rearrangements of an X-chromosome, cells with the best dosage balance are preferentially selected, frequently resulting in a skewed inactivation pattern and amelioration of the phenotype. The ...
A new class of neurotoxin from wasp venom slows inactivation of sodium current
(Blackwell Science, 2000-06-01)
The effects of alpha-pompilidotoxin (alpha-PMTX), a new neurotoxin isolated from the venom of a solitary wasp, were studied on the neuromuscular synapses in lobster walking leg and the rat trigeminal ganglion (TG) neurons. ...
Polyphenol oxidase from yacon roots (Smallanthus sonchifolius)
(Amer Chemical Soc, 2007-03-21)
Polyphenol oxidase (E.C. 1.14.18.1) (PPO) extracted from yacon roots (Smallanthus sonchifolius) was partially purified by ammonium sulfate fractionation and separation on Sephadex G-100. The enzyme had a molecular weight ...
Gas phase photocatalytic bacteria inactivation using metal modified TiO2 catalysts
(2013-02-01)
The present study describes the efficiency of heterogeneous photocatalytic reactor for the inactivation of three air born bacteria, Escherichia coli, Bacillus subtilis and Staphylococcus aureus using metal modified TiO2 ...
