pasteurella multocida is known as an important heterogenic bacterial agent causes some severe diseases such as fowl cholera in poultry and haemorrhagic septicaemia in cattle and buffalo. a polymerase chain reaction (pcr) assay was developed using primers derived from conserved part of 16s-23s rrna gene. the pcr amplified a fragment size of 0.7 kb using dna from nine avian p. multocida isolates...
This chapter shows that multinational corporations play a dual role in cluster evolution through the case of the wireless communications cluster in Northern Denmark. On the one hand, they bring in resources to the cluster, such as financial resources, technology, knowledge, innovation networks, and access to new markets. On the other hand, they cause changes in local interaction, decision makin...
conclusions the results of the current study demonstrated that type iii is the predominant type in hamedan, followed by types v, type ii, type ia, ib and iv, respectively. use of the molecular serotyping (ms) method such as pcr assay as an alternative to conventional serotyping (cs) method leads to accurate, sensitive, specific, and fast typing of gbs isolates. results among the 62 gbs isolates...
Towards the goal of producing fully human polyclonal antibodies (hpAbs or hIgGs) in transchromosomic (Tc) cattle, we previously reported that Tc cattle carrying a human artificial chromosome (HAC) comprising the entire unrearranged human immunoglobulin (Ig) heavy-chain (hIGH), kappa-chain (hIGK), and lambda-chain (hIGL) germline loci produced physiological levels of hIgGs when both of the bovin...
Mycoplasma capricolum subspecies capricolum (Mcc) is one of the causative agents of contagious agalactia (CA), which is an important disease in sheep and goats in the Mediterranean and Middle East countries. Mycoplasma agalactiae is the classic agent of CA in sheep and goats. Mycoplasma mycoides subspecies Capri (Mmc), Mycoplasma capricolum subspecies capricolum (Mcc), and Mycoplasma putrefacie...
The chloride ion, Cl(-), is an essential cofactor for oxygen evolution of photosystem II (PSII) and is closely associated with the Mn(4)Ca cluster. Its detailed location and function have not been identified, however. We substituted Cl(-) with a bromide ion (Br(-)) or an iodide ion (I(-)) in PSII and analyzed the crystal structures of PSII with Br(-) and I(-) substitutions. Substitution of Cl(-...
We propose Grid Block Energy based hierarchical Data Gathering (GBE-DG) algorithms for wireless sensor networks. We divide the whole sensor network into grid blocks of equal size. The energy level of a grid block is the sum of the energy levels of the sensor nodes located in it. The grid block that has the maximum energy level is called the leader grid block (LGB) and the sensor node that has t...
A fraction of chronic lymphocytic leukaemia (CLL) cases carry highly homologous B-cell receptors (BCR), i.e. characterized by non-random combinations of immunoglobulin heavy-chain variable (IGHV) genes and heavy-chain complementarity determining region-3 (HCDR3), often associated with a restricted selection of IGVK/L light chains. Such 'stereotyped' BCR occur more frequently in CLL with unmutat...
in the present study, randomly amplified polymorphic dna (rapd) markers were used to analyze the genetic diversity in 20 varieties of philodendron. the polymerase chain reaction was performed with 60 rapd primers, out of which 21 primers showed clear amplification as well as more polymorphism. in total, 354 scorable rapd loci with 348 polymorphic bands (98%) were observed. percentages of polymo...
This study looks at organizations’ perceptions of the importance of absorptive capacity attributes in the deployment of radio frequency identification (RFID) in a supply chain and their relationships with supply chain process integration and information technology infrastructure support. Data for this pilot research study was collected using a survey questionnaire administered online to members...
