The homeobox gene Hesx1 is an essential repressor that is required within the anterior neural plate for normal forebrain development in mouse and humans. Combining genetic cell labelling and marker analyses, we demonstrate that the absence of Hesx1 leads to a posterior transformation of the anterior forebrain (AFB) during mouse development. Our data suggest that the mechanism underlying this tr...

The goal of this study was to evaluate the effect of the specimen-processing method that uses the detergent C18-carboxypropylbetaine (CB-18) on the sensitivity of acid-fast bacillus (AFB) staining. Vietnamese immigrants with abnormal chest radiographs provided up to three sputum specimens, which were examined for acid-fast bacilli by use of direct auramine and Ziehl-Neelsen staining. The remain...

Aflatoxins B₁ (AFB₁), deoxynivalenol (DON), fumonisin B₁ (FB₁), T-2 toxin (T-2), and zearalenone (ZEA) are the major foodborne mycotoxins of public health concerns. In the present study, the multiple toxic endpoints of these naturally-occurring mycotoxins were evaluated in Caenorhabditis elegans model for their lethality, toxic effects on growth and reproduction, as well as influence on lifespa...

A new search algorithm for solving distributed constraint optimization problems (DisCOPs) is presented. Agents assign variables sequentially and propagate their assignments asynchronously. The asynchronous forward-bounding algorithm (AFB) is a distributed optimization search algorithm that keeps one consistent partial assignment at all times. Forward bounding propagates the bounds on the cost o...

Worldwide, American foulbrood (AFB) is the most devastating bacterial disease of the honey bee (Apis mellifera). Because the distinction between AFB and powdery scale disease is no longer considered valid, the pathogenic agent has recently been reclassified as one species Paenibacillus larvae, eliminating the subspecies designations Paenibacillus larvae subsp. larvae and Paenibacillus larvae su...

We list all possible dimension-six CP-conserving SUc(3)× SUL(2)× UY (1) invariant operators involving the third-family quarks which could be generated by new physics at a higher scale. Expressions for these operators after electroweak gauge symmetry breaking and the induced effective couplings Wtb̄, Xbb̄ and Xtt̄ (X = Z, γ, g,H) are presented . Analytic expressions for the tree level contributions...

Tuberculous pleural effusion occurs in approximately 5% of patients with Mycobacterium tuberculosis (TB) infection1 and accounts for 4% of all TB cases in the United States.2 Diagnosis is challenging, with 48–96% of tuberculous pleural effusions negative by sputum acid-fast bacilli (AFB) stain and culture. Thoracentesis is frequently performed and shows an exudative, lymphocytic pleural effusio...

Literature on test validity and performance validity is reviewed to propose a framework for specification of an ability-focused battery (AFB). Factor analysis supports six domains of ability: first, verbal symbolic; secondly, visuoperceptual and visuospatial judgment and problem solving; thirdly, sensorimotor skills; fourthly, attention/working memory; fifthly, processing speed; finally, learni...

We present a preliminary measurement of the forward-backward asymmetry in the production of B mesons, AFB(B ), using B → J/ψK decays in 10.4 fb of pp̄ collision data from Run II of the DØ Experiment at the Tevatron Collider. A non-zero asymmetry would indicate a preference for a particular flavor of b quark to be produced in the direction of the proton beam. AFB(B ) is extracted from a maximum l...
