this study was carried out to examine aflatoxin b1 (afb1) removal ability of four strains of lactic acidbacteria (lab). three indigenous (lactobacillus rhamnosus tmu094, lactobacillus fermentum tmu121and pedioccus pentosaceus tmu457) and a non-indigenous (labacillus rhamnosus ptcc1637) isolateswere studied. the strains were incubated with (afb1) at different time. the toxin residual in the supe...

Superantigens are bacterial, viral, retroviral and some naturally occurring proteins that can specifically activate a large proportion of T and/or B cells. In contrast to classical peptide antigen recognition, superantigens do not require processing to small peptides. T-cell superantigens interact with the immune system by binding to major histocompatibility complex (MHC) class II proteins outs...

A series of phosphorylcholine (PC) 1 binding myeloma proteins of BALB/c origin have been described and characterized by several laboratories (1-4). One group of these proteins, including among others T15, H8, and S107, has been shown to possess identical variable region antigenic determinants (idiotypes) (2, 5) as well as identical partial variable region light and heavy chain amino acid sequen...

Coagulation factors belong to a family of plasma glycosylated proteins that should be activated for appropriate blood coagulation. Congenital deficiencies of these factors cause inheritable hemorrhagic diseases. Factor VII (FVII) deficiency is a rare bleeding disorder with variable clinical symptoms. Various mutations have been identified throughout the F7 gene and can affect all the protein do...

We develop a structural VAR in which an occasionally-binding constraint generates censoring of one the dependent variables. Once mechanism is triggered, we allow some coefficients for remaining variables to change. show that necessary condition unique reduced form regression functions non-censored are continuous at point and parameters satisfy mild restrictions. In our application censored vari...

syntax is not sufficiently abstract Parse trees take no account of variable binding. ∫ x 0 (∫ y 1 xy dx )

A variable-structure (VS) PID controller for the level process is proposed. A methodology of analysis of its stability and performance is given. It is proposed that stability of the VS system can be approximately analyzed via the describing function method. The describing function of the VS PID controller is derived. It is shown that the system with the VS PID controller is quasi-linear. Tuning...
