This study investigates the role of the activated polymorphonuclear cell (APMN) products on sickle red blood cell (SRBC) retention/adherence in the pulmonary circulation. Isolated rat lungs were perfused with (51)Cr-labeled normal RBCs (NRBC) or SRBCs (10% hematocrit) suspensions +/- PMNs. Specific activities of lung and perfusate were measured and retention (the number of SRBC/g lung) was calc...

Temporal fenestration has long been considered a key character to understand relationships amongst reptiles. In particular, the absence of the lower temporal bar (LTB) is considered one of the defining features of squamates (lizards and snakes). In a re-assessment of the borioteiioid lizard Polyglyphanodon sternbergi (Cretaceous, North America), we detected a heretofore unrecognized ontogenetic...

A novel nontoxic form of chimeric mucosal adjuvant that combines the A subunit of mutant cholera toxin E112K with the pentameric B subunit of heat-labile enterotoxin from enterotoxigenic Escherichia coli was constructed by use of the Brevibacillus choshinensis expression system (mCTA/LTB). Nasal immunization of mice with tetanus toxoid (TT) plus mCTA/LTB elicited significant TT-specific immunog...

The Caushy problem in the LTB model is formulated. The rules of calculating three undetermined functions which defined a solution in the LTB model are presented. One example of exact nonhomogeneous model is studied. The limit transformation to the FRW model is shown. PACS number(s):98.80

Many recent researches have investigated the deviations from Friedmannian cosmological model, as well their consequences on unexplained phenomena, such dark matter and acceleration of Universe. On one hand, a first-order perturbative study inhomogeneity returned partial explanation energy, relativistic effects due to retarded potentials far objects. other fractal cosmology, now approximated by ...

E. coli O157:H7, one of the major EHEC serotypes, is capable of developing bloody diarrhea, hemorrhagic colitis (HC), and fatal hemolytic uremic syndrome (HUS) and is accompanied by high annual economic loss worldwide. Due to the increased risk of HC and HUS development following antibiotic therapy, the prevention of infections caused by this pathogen is considered to be one of the most effecti...

Enterotoxigenic Escherichia coli (ETEC)-induced diarrhoea is the second most commoncause of death in children in the developing countries. Heat labile toxin (LT) is responsible forETEC-induced diarrhoea. In the present study, a novel live ETEC vaccine based on subunitB of LT (LTB) expression in attenuated PhoPc Salmonella strain was developed. Herein, weaimed to compare the in-vitro activity of...
