Cryptosporidium intestinal parasites have been detected in farmed pigs worldwide. Infections are usually asymptomatic with a low number of oocysts shed in pig feces. This makes the recognition of infection difficult or unsuccessful when microscopic methods are used. The aim of this study was molecular identification of Cryptosporidium species in pig herds raised in Poland with regard to the occ...

The association constants Kb of three hosts I-III designed to have both enhanced hydrogen bonding donor strength and conformational preorganization with biotin analogues 1-5 are reported. 1H-NMR titrations under two different concentration conditions have been employed to determine the association constants Kb. A statistical analysis using a presence absence matrix has been applied to calculate...

The experimental investigation of elementary chemical reactions is presently in a very exciting period. The advance in modern microscopic experimental methods, especially crossed molecular beams and laser technology, has made it possible to explore the dynamics and mechanisms of important elementary chemical reactions in great detail. Through the continued accumulation of detailed and reliable ...

abstract: subgroup j avian leukosis virus (alv-j) was isolated in the late 1980s from meat-type chickens in the united kingdom. alv-j with exception of some acute variants, cause myeloid leukosis in meat-type chickens with long incubation period.in this study while the status of avian leukosis virus subgroup j in six different strain of broiler grandparent flocks of iran evaluated, the evaluati...

at is an autosomal recessive disorder characterized by early onset progressive cerebellar ataxia, oculocutaneous telangiectasia, bronchopulmonary, lymphoid tumors, immunodeficiency and chromosomal instability. the defective gene is atm (at mutated) localized in chromosome 11q22-23. at patients are at risk of cancer, which is the second cause of death in this disease. iranian at patients have ma...

The translocon is a protein-conducting channel conserved over all domains of life that serves to translocate proteins across or into membranes. Although this channel has been well studied for many years, the recent discovery of a high-resolution crystal structure opens up new avenues of exploration. Taking advantage of this, we performed molecular dynamics simulations of the translocon in a ful...

Introduction Galactose oxidase (GOase; EC 1.1.3.9) is a coppercontaining enzyme that is secreted by certain filamentous fungi, and is the subject of a recent review [ 11. The most extensively studied source of the enzyme is the strain no. 2003 of the Northern Regional Research Laboratory (NKKI,) collection, Peoria, II,, lJ.S.A. [2]. This fungus is designated as Dactylium dendroides [ 3 1, howev...

The ability to predict the transport and transformations of contaminants within the subsurface is critical for decisions on virtually every waste disposal option facing the Department of Energy (DOE), from remediation technologies such as in situ bioremediation to evaluations of the safety of nuclear waste repositories. With this fact in mind, the DOE has recently sponsored a series of workshop...
