BACKGROUND Maternal malaria is associated with serious adverse pregnancy outcomes. One recommended means of preventing malaria during pregnancy is intermittent preventive therapy (IPTp) with sulfadoxine/pyrimethamine (SP). We sought to identify determinants of preventive use of SP during pregnancy among recently pregnant women in Uganda. Additionally, we characterized the timing of and indicati...

Eight species of Dactylogyridae collected from the barrages of the Nile River near Cairo, Egypt, are reported from the external surfaces of Clarias lazera Cuvier and Valenciennes as follows: Quadriacanthus clariadis Paperna, 1961, Q. aegypticus El-Naggar and Serag, 1986, Q. allobychowskiella Paperna, 1979, Q. bagme Paperna, 1979, Q. papernai sp. n., Q. ashuri sp. n., Q. numidus sp. n., and Quad...

The second paper of the series about Ampharetidae from Japan includes twelve species of four genera with elevated and modified notopodia, Anobothrus Levinsen, 1884, Sosane Malmgren, 1866 (including species of the synonymized genera Muggoides Hartman, 1965, Sosanopsis Hessle, 1917, and Genus A sensu Uebelacker 1984), Tanseimaruana gen. nov., and Zatsepinia Jirkov, 1986. Tanseimaruana gen. nov. i...

BACKGROUND A simple and rapid slide Polybrene method (SP) for pretransfusion compatibility testing is described. SP is particularly suitable for use in developing countries where, due to limited resources, centrifuges and biologic reagents may not be readily available. STUDY DESIGN AND METHODS The original manual Polybrene method (MP) was modified for use on glass microscope slides, eliminati...

Min et al. (2009) presented two complementary techniques that use the diffusion approximation to allow efficient Monte-Carlo radiation transfer in very optically thick regions: a modified random walk and a partial diffusion approximation. In this note, I show that the calculations required for the modified random walk method can be significantly simplified. In particular, the diffusion coeffici...

Hematopoietic regulation is a complex but dynamic process regulated by intercellular and intracellular interactions within the bone marrow (BM) microenvironment. Through neurokinin-1 (NK-1) and NK-2 receptors, peptides (eg, substance P [SP]) encoded by the preprotachykinin-I gene mediate distinct hematopoietic effects. Cytokines, associated with hematopoietic stimulation, and SP regulate the ex...

I analyzed 28 fecal samples from Andean bears (Tremarctos ornatus) collected between 2003 and 2007 from the Laquipampa Wildlife Refuge and Yanachaga Chemillén National Park, Peru. I used the direct faeces test and spontaneous sedimentation tube technique to detect cysts, ova, and larvae. To detect intestinal coccidia, I applied acid stain using the Ziehl–Neelsen modified method. I detected para...

In our study, surfactant protein (SP)-A was characterized in adult human trachea and bronchi. SP-A mRNA and protein were localized to serous cells in submucosal gland by in situ hybridization and immunohistochemistry, respectively. A 2.2 kb SP-A mRNA transcript was detected in tracheal tissues by Northern blot analysis. Primer extension analysis and gene-specific reverse transcriptase polymeras...

A fragment of the Helicosporidium sp. (Chlorophyta: Trebouxiophyceae) plastid genome has been sequenced. The genome architecture was compared to that of both a non-photosynthetic relative (Prototheca wickerhamii) and a photosynthetic relative (Chlorella vulgaris). Comparative genomic analysis indicated that Helicosporidium and Prototheca are closely related genera. The analyses also revealed th...
