The Paternal Adjustment and Paternal Attitudes Questionnaire (PAPA) was designed to assess paternal adjustment and paternal attitudes during the transition to parenthood. This study aimed to examine the psychometric characteristics of the Portuguese versions of the PAPA-Antenatal (PAPA-AN) and -Postnatal (PAPA-PN) versions. A nonclinical sample of 128 fathers was recruited in the obstetrics out...

A new reweighted proportionate affine projection algorithm (RPAPA) with memory and row action projection (MRAP) is proposed in this paper. The reweighted PAPA is derived from a family of sparseness measures, which demonstrate performance similar to mu-law and the l0 norm PAPA but with lower computational complexity. The sparseness of the channel is taken into account to improve the performance ...

P fimbrial adhesins may be associated with the virulence of avian pathogenic Escherichia coli (APEC). However, most APECs are unable to express P fimbriae even when they are grown under conditions that favor P fimbrial expression. This failure can be explained by the complete absence of the pap operon or the presence of an incomplete pap operon in Pap-negative APEC strains. In the present study...

One Saturday morning when Miriam was four, we went to breakfast at the Cracker Barrel. She asked if we could go look at the toys while we waited for our order. We walked hand in hand past the greeter and the greeter kindly smiled at us and said to Miriam "how nice you are spending the day with grandpa." I smiled and Miriam gripped my hand and said defiantly to the woman "he is my papa not my gr...

Ternary complexes of plasmid DNA, histone H1 protein and amphipathic polyamines (PAPA) were able to mediate the efficient transfection of 3T3. HeLa and COS cells in culture. Using both the beta-galactosidase and luciferase reporter gene systems, the transfection efficiency of PAPA complexes was comparable to that of DOSPA/PE cationic liposomes, considered to be a highly-efficient transfection r...

A gene that encodes an extracellular aspartyl protease from Trichoderma harzianum CECT 2413, papA, has been isolated and characterized. Based on several conserved regions of other fungal acid proteases, primers were designed to amplify a probe that was used to isolate the papA gene from a genomic library of T. harzianum. papA was an intronless ORF which encoded a polypeptide of 404 aa, includin...

Papyriflavonol A (PapA), a prenylated flavonoid (5,7,3',4'-tetrahydroxy-6,5'-di-(r,r-dimethylallyl)-flavonol), was isolated from the root barks of Broussonetia papyriferra. Our previous study showed that PapA has a broad-spectrum antimicrobial activity against pathogenic bacteria and fungi. In this study, the mode of action of PapA against Candida albicans was investigated to evaluate PapA as a...

N-Phenylacetyl-L-phenylalanine (PAP) and L-phenylalanyl-3-aminopyridine ( PAPA ) are biaromatic agents with properties that make them suitable candidates for the development of a useful therapeutic agent for the treatment of sickle cell disease. PAP and PAPA are taken up by the erythrocyte to give intra-/extracellular concentration ratios of 2.2 and 1.5, respectively, after a 2-hr exposure peri...

A nomenclatural review of Sarcoramphus vultures resulted in the following: The genus Sarcoramphus was described by Duméril in 1805 rather than 1806. Vultur papa Linnaeus, 1758, is the type of Sarcoramphus by subsequent monotypy (Froriep in Duméril 1806), not by Vigors's (1825) designation. The type of the genus Gypagus Vieillot, 1816, is, by monotypy, Vultur gryphus Linnaeus, 1758, not Vultur p...

PAPA syndrome (Pyogenic Arthritis, Pyoderma gangrenosum, and Acne) is an autosomal dominant, hereditary auto-inflammatory disease arising from mutations in the PSTPIP1/CD2BP1 gene on chromosome 15q. These mutations produce a hyper-phosphorylated PSTPIP1 protein and alter its participation in activation of the "inflammasome" involved in interleukin-1 (IL-1β) production. Overproduction of IL-1β i...
