abstract one of the best reliable markers of hepatitis b virus infection is antibodies to the core antigen (anti-hbc). a first-time blood donor with hbsag positivity was identified as an hbv carrier that was anti-hbc negative. the patient was followed for 24 months in order to investigate the evolution of his hbv serological profiles and hbvdna (pcr). in the follow-up for 24 months, hbsag, hbea...

Our previous studies showed that bovine respiratory syncytial virus (BRSV) followed by Histophilus somni causes more severe bovine respiratory disease and a more permeable alveolar barrier in vitro than either agent alone. However, microarray analysis revealed the treatment of bovine alveolar type 2 (BAT2) epithelial cells with H. somni concentrated culture supernatant (CCS) stimulated up-regul...

the risks of transmitting viral infection by blood and plasma-derived products have long been known and still remain an area of concern. in this study, in the process of purifying human factor vii from prothrombin complex, sid treatment using tri-n-butyl phosphate and tween 80 was employed and its capability and efficacy was studied. the results indicated that the process did not affect the bio...

The articles [8], [5], [9], [1], [10], [11], [3], [2], [7], [4], and [6] provide the notation and terminology for this paper. We consider tree construction structures as extensions of 1-sorted structure as systems 〈 a carrier, rules 〉, where the carrier is a set and the rules constitute a relation between the carrier and the carrier∗. Let us note that there exists a tree construction structure ...

(Def. 2) lenpr2(h1) = lenh1 and for every n such that n ∈ dompr2(h1) holds pr2(h1)(n) = h1(n)2. Let us consider A, B, let f1 be a homogeneous quasi total non empty partial function from A∗ to A, and let f2 be a homogeneous quasi total non empty partial function from B∗ to B. Let us assume that arity f1 = arity f2. The functor ee f1, f2dd yields a homogeneous quasi total non empty partial functi...

We consider CLS structures as extensions of loop structure as systems 〈 a carrier, a zero, an addition, an external multiplication 〉, where the carrier is a set, the zero is an element of the carrier, the addition is a binary operation on the carrier, and the external multiplication is a function from [: C, the carrier :] into the carrier. Let us observe that there exists a CLS structure which ...
