BACKGROUND Although many malaria control programmes in sub-Saharan Africa use indoor residual spraying with long-lasting insecticidal nets (LLINs), the two studies assessing the benefit of the combination of these two interventions gave conflicting results. We aimed to assess whether the addition of indoor residual spraying to LLINs provided a significantly different level of protection against...

STUDY QUESTION Does the chance of pregnancy keep improving with increasing number of oocytes, or can you collect too many? SUMMARY ANSWER Clinical pregnancy (CP) and live birth (LB) rates per embryo transfer varied from 10.2 and 9.2% following one oocyte collected to 37.7 and 31.3% when >16 oocytes were collected. Regression modelling indicated success rates increased or at least stayed the s...

Listeria monocytogenes is an important foodborne pathogen with a persistent ability to form biofilm matrices in the food processing environments. In this study, we have determined the ability of bacteriophage P100 to reduce L. monocytogenes cell populations under biofilm conditions by using 21 L. monocytogenes strains representing 13 different serotypes. There were considerable differences in t...

We incorporate a mixture of polystyrene (PS) and the highly conductive N,N′-diphenyl-N,N′-bis(3-methylphenyl)-[1,1′-biphenyl]4,4′-diamine (TPD) as charge transporting agent into a photorefractive composite, wherein the liquid crystal 4-cyano-4-n-pentylbiphenyl (5CB) is the electro-optical unit and the perylene bisimide dimer DiPBI acts as sensitizing component. Investigation of the photocurrent...

Coded Video Tra c Hai Liu, Nirwan Ansari, and Yun-Qing Shi Abstract: Self-similar processes, modulated according to the MPEG frame structure, are proposed to capture both the SRD (short range dependency) and LRD (long range dependency) of MPEG video tra c. Introduction: Tra c generated by video applications is increasingly cramming existing networks, and it is thus essential to accurately chara...

The initiation of DNA replication of plasmid R6K is triggered by a 35-kldodalton initiator protein. The initiator protein had been elusive because of its lability and the lack of a convenient assay procedure to aid its purification. Using recombinant DNA techniques, we have fused the cistron of the initiator near its COOH-terminal end, in the correct reading frame, to the lacZ cistron of Escher...

Nucleophilic trapping of iminium salts generated via oxidative functionalisation of tertiary amines is well established with stabilised carbon nucleophiles. The few reports of organometallic additions have limited scope of substrate and organometallic nucleophile. We report a novel, one-pot methodology that functionalises N-substituted tetrahydroisoquinolines by visible lightassisted photooxida...
