Accurate PCR detection of influenza A/B and respiratory syncytial viruses by use of Cepheid Xpert Flu+RSV Xpress Assay in point-of-care settings: Comparison to Prodesse ProFlu+

ABSTRACT The Xpert Flu+RSV Xpress Assay is a fast, automated in vitro diagnostic test for qualitative detection and differentiation of influenza A and B viruses and respiratory syncytial virus (RSV) performed on the Cepheid GeneXpert Xpress System. The objective of this study was to establish performance characteristics of the Xpert Flu+RSV Xpress Assay compared to those of the Prodesse ProFlu+ real-time reverse transcription-PCR (RT-PCR) assay (ProFlu+) for the detection of influenza A and B viruses as well as RSV in a Clinical Laboratory Improvement Amendments (CLIA)-waived (CW) setting. Overall, the assay, using fresh and frozen nasopharyngeal (NP) swabs, demonstrated high concordance with results of the ProFlu+ assay in the combined CW and non-CW settings with positive percent agreements (PPA) (100%, 100%, and 97.1%) and negative percent agreements (NPA) (95.2%, 99.5%, and 99.6%) for influenza A and B viruses and RSV, respectively. In conclusion, this multicenter study using the Cepheid Xpert Flu+RSV Xpress Assay demonstrated high sensitivities and specificities for influenza A and B viruses and RSV in ∼60 min for use at the point-of-care in the CW setting. </jats:p

Anti-inflammatory and analgesic effects of ketoprofen in palm oil esters nanoemulsion

Ketoprofen is a potent non-steroidal anti-inflammatory drug has been used in the treatment of various kinds of pains, inflammation and arthritis. However, oral administration of ketoprofen produces serious gastrointestinal adverse effects. One of the promising methods to overcome these adverse effects is to administer the drug through the skin. The aim of the present work is to evaluate the anti-inflammatory and analgesic effects from topically applied ketoprofen entrapped palm oil esters (POEs) based nanoemulsion and to compare with market ketoprofen product, Fastum® gel. The novelty of this study is, use of POEs for the oil phase of nanoemulsion. The anti-inflammatory and analgesic studies were performed on rats by carrageenan-induced rat hind paw edema test and carrageenan-induced hyperalgesia pain threshold test to compare the ketoprofen entrapped POEs based nanoemulsion formulation and market formulation. Results indicated that there are no significant different between ketoprofen entrapped POEs nanoemulsion and market formulation in carrageenan-induced rat hind paw edema study and carrageenan-induced hyperalgesia pain threshold study. However, it shows a significant different between POEs nanoemulsion formulation and control group in these studies at p<0.05. From these results it was concluded that the developed nanoemulsion have great potential for topical application of ketoprofen

Urban forest fragmentation impoverishes native mammalian biodiversity in the tropics

Urban expansion has caused major deforestation and forest fragmentation in the tropics. The impacts of habitat fragmentation on biodiversity are understudied in urban forest patches, especially in the tropics and little is known on the conservation value of the patches for maintaining mammalian biodiversity. In this study, camera trapping was used to determine the species composition and species richness of medium‐ and large‐sized mammals in three urban forest patches and a contiguous forest in Peninsular Malaysia. We identified the key vegetation attributes that predicted mammal species richness and occurrence of herbivores and omnivores in urban forest patches. A total number of 19 mammal species from 120 sampling points were recorded. Contiguous forest had the highest number of species compared to the urban forest patches. Sunda Pangolin and Asian Tapir were the only conservation priority species recorded in the urban forest patches and contiguous forest, respectively. Top predators such as Malayan Tiger and Melanistic Leopard were completely absent from the forest patches as well as the contiguous forest. This was reflected by the abundance of wild boars. We found that mammal species richness increased with the number of trees with DBH less than 5 cm, trees with DBH more than 50 cm, and dead standing trees. In the future, the remaining mammal species in the urban forest patches are expected to be locally extinct as connecting the urban forest patches may be infeasible due to land scarcity. Hence, to maintain the ecological integrity of urban forest patches, we recommend that stakeholders take intervention measures such as reintroduction of selected species and restocking of wild populations in the urban forest patches to regenerate the forest ecosystems

Genetics of yield and its components in egg plant (Solanum melongena L.)

Inheritance study for yield and its components were conducted in five selected parents of brinjal namely MTE 1, MTE 2, Terung Bujur, Terung Telunjuk and NTH080077. Parents, F1 and F2 progenies were evaluated under field condition at MARDI, Serdang. Data on vegetative and yield components were recorded for parents F1 and F2 populations. Genetics study for inheritance were evaluated, and it showed that days to flower, fruit number per plant and fruit weight were observed as additive gene effect. Whereas, plant height and yield per plant were dominance gene effect. High heritability and high genetic advance were observed for fruit number per plant, fruit weight and yield per plant. Low and moderate phenotypic and coefficient of variations were observed for all traits. Moderate phenotypic and coefficient of variations were expressed by fruit number per plant, fruit weight and yield per plant. The selection of genotypes with high heritability coupled with genetic advance for these traits indicates the potential for crop improvement through selection

Formulation and characterization of palm oil esters based nano-cream for topical delivery of piroxicam

Palm oil esters are high molecular weight esters oil that has been newly synthesized by University Putra Malaysia researchers. It has received a lot of attention for its pharmaceutical and chemical application. Piroxicam is a nonsteroidal anti-inflammatory drug with analgesic and antipyretic activity. It has low solubility in water as well as in oil with Log P value of 1.8. Generally, drugs with Log P value of more than 0.5 are needed to be formulated into a modified dosage form. One of these formulations is nano sized cream. Hence, the ability of formulating of these tricky drugs into dispersed system is questionable. The aim of this study is to investigate the ability of palm oil esters to be the oil phase for formulation of piroxicam into O/W nano-cream. Three points were selected from prepared pseudoternary diagram of palm oil esters and different Tween and Span mixtures. Piroxicam solubility and partition coefficient in oil and external phase was detected. Rheological properties, droplet size, structural properties and zeta potential of the dispersion system containing piroxicam were measured. O/W cream was formed with droplet size measurement by TEM of less than 100 nm. It could be concluded that palm oil esters is suitable oil for the formulation of suitable nano-cream containing piroxicam.Keywords: Palm oil esters; Piroxicam Solubility; partition coefficient; Rheology; Surface activity

Stability studies of nano-cream containing piroxicam

The aim of this study is to study the stability of the nano-cream formula containing the newly synthesized palm oil esters when stored for reasonable storage duration. The prepared 0.5% piroxicam nano-cream formula contained phosphate buffer as external phase, palm oil esters as the oil phase and a combination of (80:20) of Tween 80 and Span 20 as emulsifier at a ratio of 37:25:38, respectively. Piroxicam is a hydro-lipophobic drug. Stability on storage is an important aspect which ensures the dosage form can exert the effects it is supposed to exert for the duration of storage. Droplets size, electrical conductivity, drug content, pH and rheological parameters are the parameters that have been assessed under different temperature to evaluate the stability of nano-cream preparation. Thus, experiments which measure the above parameters were conducted at storage temperatures of 4, 25 and 40οC.The data obtained from the stability study conducted on nano-cream formula showed that this formulation was stable for the whole 3 months period of the study when stored at tested several temperatures.Keywords: Palm oil esters; Nonionic surfactant; Piroxicam; Nano-crea

Energy efficient electrocoagulation using baffle-plates electrodes for efficient Escherichia Coli removal from Wastewater

A new electrocoagulation reactor (EC), which utilises the concepts of baffle-plates, has been applied to remove Escherichia coli (E. coli) from wastewater. This new aluminium-based EC reactor utilises perforated baffle-plates electrodes to mix water, which reduces the need for mechanical or magnetic mixers that require extra power to work. This new reactor has been used to treat E. coli containing wastewater samples, considering the effects of different parameters such as treatment time (TT), inter-electrode distance (IED), and current density (CD). A statistical analysis has also been commenced to evaluate the influence of each parameter on the removal of E. coli. Additionally, an economic study has been conducted to assess the operating cost of the new reactor. The outcomes of the experimental work confirmed that the new reactor removes as high as 96% of the E. coli within 20 minutes of electrolysis at IED of 0.5 cm, and CD of 1.5 〖mA/cm〗^2. Additionally, it has been found that the operating cost of the new reactor is 0.11 US $/m3 (for E. coli removal), which is less than operating cost of traditional reactors. Finally, it has been found that the effect of the studied parameters on E. coli removal followed the order: TT>CD>IED
