Molecular methodologies were used to identify 28 Achromobacter spp. from patients with cystic fibrosis (CF). Multilocus sequence typing (MLST) identified 17 Achromobacter xylosoxidans isolates (all bla(OXA-114) positive), nine Achromobacter ruhlandii isolates (all bla(OXA-114) positive), one Achromobacter dolens isolate, and one Achromobacter insuavis isolate. All less common species were misid...

Many studies have reported the phytotoxicity of allelopathic compounds under controlled conditions. However, more field studies are required to provide realistic evidences for the significance of allelopathic interference in natural communities. We conducted a 2-years field experiment in a semiarid plant community (NE Spain). Specifically, we planted juvenile individuals and sowed seeds of Sals...

The albA gene from Klebsiella oxytoca encodes a protein that binds albicidin phytotoxins and antibiotics with high affinity. Previously, it has been shown that shifting pH from 6 to 4 reduces binding activity of AlbA by about 30%, indicating that histidine residues might be involved in substrate binding. In this study, molecular analysis of the albA coding region revealed sequence discrepancies...

This paper presents ALBA-R, a protocol for convergecasting in wireless sensor networks. ALBA-R features the cross-layer integration of geographic routing with contention-based MAC for relay selection and load balancing (ALBA) as well as a mechanism to detect and route around connectivity holes (Rainbow). ALBA and Rainbow (ALBA-R) together solve the problem of routing around a dead end without o...

The aqueous leaf extracts of Basella alba were investigated in the present study for their in-vitro effect on red blood cell fragility in clinically confirmed HbSS subjects. A total of 12 human subjects, six (6) male and six (6) female with HbSS were used for this study. In-vitro osmotic fragility was determined spectrophotometrically by obtaining optical density at wavelength of 540nm. 5-6 ml ...

Background The innate immune system plays a crucial role in the initiation and subsequent direction of adaptive immune responses, as well as in the removal of pathogens that have been targeted by an adaptive immune response. Objective Morus alba L. was reported to have immunostimulatory properties that might protect against infectious diseases. However, this possibility has not yet been explo...

The aqueous and ethanol extracts of the leaves of Basella alba L. var. alba Wight, Basellaceae, were investigated for antiulcer activity on rats employing the pylorus ligation and ethanol induced ulcer models. The various gastric secretion parameters such as total acidity, free acidity, gastric acid volume, pH and histopathological parameters such as ulcer index and percent protection were comp...

--The inhibition of the corrosion of mild steel in hydrochloric acid solutions by the extract of Artemisia Herba-Alba has been studied using gravimetric and electrochemical measurement. Inhibition was found to increase with increasing concentration of the inhibitor. Values of inhibition efficiency calculated from weight loss and potentiodynamic polarization are in good agreement. This value goe...

Hypercholesterolemia is the major risk factor that leads to atherosclerosis. Nowadays, alternative treatment using medicinal plants gained much attention since the usage of statins leads to adverse health effects, especially liver and muscle toxicity. This study was designed to investigate the hypocholesterolemic and antiatherosclerotic effects of Basella alba (B. alba) using hypercholesterolem...

The Paeoniae Radix Alba-Atractylodis Macrocephalae Rhizoma herbal pair is mainly used for regulating the functions of liver and spleen, benefiting qi, and nourishing blood. However, the bioactive compounds for the pharmacological activities of the crude and processed Paeoniae Radix Alba-Atractylodis Macrocephalae Rhizoma herbal pair extracts are still unclear to date. In the present study, Q Ex...
