Eggs of Aedes albopictus were collected in oviposition cups from 3 forested areas of Delta State in south-central Nigeria during September 1991 as part of a post-yellow fever outbreak investigation. These eggs were shipped to the Centers for Disease Control in Colorado, where they were reared to the adult stage and identified. This is the first record of breeding populations of Ae. albopictus i...

in southeast asia, aedes aegypti (l.) has been incriminated as principal vector of dengue viruses and ae. albopictus as the secondary vector of dengue fever. therefore, the aim of this study was to investigate the effectiveness of three for-mula tions of pyrethrin derived from tanacetum cinerariaefolium against the dengue/dengue haemorrhagic fever vectors aedes aegypti and ae. albopictus in the...

The spatial distribution and preadult mortality patterns of 4 cohabiting species of Aedes mosquitoes were studied in a temporary vernal pool at Mt. Carmel, CT, from March to May 1990. The dominant species was Ae. stimulans (79.9%), followed by Ae. canadensis (10.7%), Ae. excrucians (7.5%) and Ae. cinereus (1.9%). First instar larvae of all species aggregated at the edge of the pool and then dis...

This study aimed to estimate the adverse events (AE) rate during anti-tuberculosis treatment and to explore AE-related risk factors. New and previously treated smear-positive tuberculosis (TB) cases were enrolled from eight regions in China between April 2009 and October 2010. The AE rate was estimated, and AE risk factors during anti-TB treatment were assessed using Cox proportional models. Am...

Activating enzyme (AE) is responsible for the in vitro activation of inactive Fe protein of nitrogenase from Rhodospirillum rubrum cells cultured anaerobically with glutamate as the N source. The expression of Fe protein and AE was examined in R. rubrum cultured photosynthetically or aerobically on media containing malate as the carbon source. One of the following N sources was used in each cul...

The susceptibility of Aedes aegypti to Ascogregarina culicis and Aedes albopictus to Ascogregarina taiwanensis was examined with mosquito and parasite strains from Tampa, FL. When each host was bioassayed with its natural gregarine, the infection intensity indicated that Ae. aegypti was 59% more susceptible to A. culicis (87 gamonts/larva) than Ae. albopictus to A. taiwanensis (47 gamonts/larva...

coustic emission (AE) techniques have been used * of arrival-time differences (delta-T’s) for each mesh point. To in the study of crack location, cracking mecha‘ calculate the source position for a set of burst-type AE signisms, deformation of metals and leak detection. : nals, a straightforward “shift and a d d method was used. A In these techniques, AE sensors hit by transient . First, assumi...

In this work, the backward Bayesian multiple linear regression (BBMLR) as a new approach is presented to predict the adsorption efficiency (AE) of Cd(II) ions by ostrich bone char (OBC) in the fixed bed adsorption with four operational variables consisting of pH (2-9), inlet Cd(II) concentration (Co= 25-100 mg/L), bed depth (h= 3-9 cm) and feed flow rate (Q= 0.5-30 mL/min). The performance of t...

The aim of the present study was to explore the effect of aloe-emodin (AE)-induced photodynamic activity in human gastric cancer cells. AE was used as a photosensitizer to explore the effect of photodynamic therapy (PDT) in human gastric cancer cells (SGC-7901). An MTT assay was used to detect the effect of AE-induced PDT in optimal concentrations and illumination energy densities in human gast...
