Nucleated red blood cells (NRBC) in blood samples interfere with the white blood cell (WBC) count on many types of automated haematology analysers. This makes it necessary to correct the WBC count by counting NRBC microscopically. This report describes the evaluation of two analysers, the Cell-Dyn 4000 and the Sysmex XE-2100, which use new techniques to recognize and enumerate NRBC. We conclude...

We re-visit the recently published paper on a generalization of the two-sex logistic model by Maxin and Sega [A generalized two-sex logistic model, J. Biol. Dyn. 7(1) (2013), pp. 302-318]. We show that the logistic assumption of a non-increasing birth rate can be replaced by a more general assumption of a non-increasing ratio between the female/male birth and mortality rate. In this note we ind...

The competitive adsorption of lung surfactant (LS) and albumin at the air-liquid interface and the ability of polyethylene glycol (PEG) to mediate LS adsorption are analyzed using pressure-area isotherms and grazing incidence x-ray diffraction (GIXD). The addition of albumin drastically reduces the amount of LS on the interface and slightly increases the LS lattice spacing. The addition of PEG ...

BACKGROUND AND PURPOSE In a large number of patients with Leigh syndrome (LS) and cytochrome c oxidase (COX) deficiency, mutations of the SURF-1 gene were recently identified. The aim of the present study was to review the MR findings in patients with LS to verify if the genetically homogeneous patients with LS and SURF-1 mutations (LS SURF-1 patients) had a homogeneous MR pattern that could be...

The system [FeL2](BF4)2 (1)-EtOH-H2O (L is 4-(3,5-dimethyl-1H-pyrazol-1-yl)-2-(pyridin-2-yl)-6-methylpyrimidine) shows a complicated balance between the relative stabilities of solvatomorphs and polymorphs of the complex [FeL2](BF4)2. New solvatomorphs, 1(LS)·EtOH·H2O and β-1(LS)·xH2O, were isolated in this system. They were converted into four daughter phases, 1(A/LS), 1(D/LS), 1(E/LS)·yEtOH·z...

Recent observations in our laboratories (1, 2) have demonstrated that a single molecular substance carries all of the serological activity of both the Land Ssoluble antigens of vaccinia. Craigie and Wishart, (3) who originally described these two antigens thought that they occurred in the form of a complex in nature, but, from their own observations (3) and from those of Parker (4), they were l...

This paper discusses a novel approach for the construction of a context-free grammar based on a sequential processing of sentences. The construction of the grammar is based on a search algorithm for the minimum weight subgraph in an AND/OR graph. Aspects of optimality and robustness are discussed. The algorithm plays an essential role in a model for adaptive learning of probabilistic ordering. ...

Chronic opioid agonist treatment produces tolerance and in some cases opioid receptor internalization and down-regulation. Both morphine and etorphine induce tolerance; however, only etorphine produces -opioid receptor ( OR) down-regulation. In vitro studies implicate dynamin-2 (DYN-2) and Gprotein receptor kinase-2 (GRK-2) in these processes. Therefore, we examined etorphine and morphine effec...

This display sketches one element of the Digital Youth Network, a program aimed at producing digitally literate youth. The practices of program leaders blend those of mentoring and teaching. Despite the potential conflict between these roles, program leaders structure activities to support role transitions. The management of youth behavior within this structure supports the successful transitio...
