An improved rapid one-pot and green synthesis of substituted pyranopyranes by condensing Kojic acid, malononitrile, and different aldehydes and using a catalytic amount of cobalt nanoparticles as green and reusable catalyst is reported for the first time. The reaction proceeds in aqueous media at ambient temperature. Furthermore, the structural and morphological study of the cobalt nanoparticle...

Here, we describe the validation of a new phenotypic culture-based AtbFinder method for rapid selection antibiotics in vitro using specimens with mono- and polybacterial infections. AtbFinder, which can be applied to any type non-blood tissue, does not require isolation pure bacterial cultures. The uses novel TGV medium that allows more growth Gram-positive Gram-negative monoisolates compared a...

Background. Obesity, through creating disorder in blood lipids and also, increase insulin resistance, has a main role in appearance high risk disease such as cardiovascular disease, diabetes and various kind of cancer. Objectives. The aim of this study was to survey effect of eight weeks continuous aerobic training accompanied with green tea consumption on lipid profile of inactive obese fe...

The purpose of this study was to test the applicability of the API 20E and API Rapid NFT systems for the identification of some predominant gram-negative and gram-positive bacteria isolated from lab-scale activated sludge treatment systems. In this study, one lab-scale sequencing batch reactor (SBR) and one lab-scale continuous-flow stirred tank reactor (CFSTR) were setup. After both reactors h...

OBJECTIVE To assess the most common micro-organisms causing odontogenic infections and their antimicrobial susceptibility. METHODS The study was conducted in 80 patients with orofacial infection. The pus sample was collected, cultured (aerobically and anaerobically) and stained for morphological study of the isolates. Antibiotic sensitivity test for the isolates were performed. RESULTS A to...

In a meta-analysis examining respiratory specimen Gram stain for diagnosis of ventilator-associated pneumonia, absence of bacteria on Gram stain had a high negative predictive value, but a positive Gram stain correlated poorly with organisms recovered in culture. Rapid and accurate diagnosis of ventilator-associated pneumonia (VAP) is a major challenge and no generally accepted gold standard ex...

organizations in order to capture sustainability and competitive advantage need to pay attention to environmental issues throuoghout their supply chain. by decreasing costs, improving image and being protected against environmental laws it can lead to organizational competitive advantage. current research has been done investigating the relationship between green supply chain and capturing cope...
