ZnO and TiO2 are semiconductor nanomaterials that widely used in photocatalysis. However, the relatively high recombination rate low quantum yield of photogenerated electron–hole pairs limit their practical applications. In this study, a series TiO2/ZnO/diatomite composites with various compositions were successfully prepared via two-step precipitation method. They exhibited stronger UV–visible...

The sensory properties of fruit and vegetables are a result taste aroma caused by many volatile nonvolatile compounds. sum organic acids (malic citric acids) soluble sugars (fructose glucose), as well their balanced combination interaction, contributes to the characterization tomato flavour. ratio is key sweetness sourness tomatoes. This study aimed determine sugar acid content, several physico...

background and objectives: baneh tree or pistacia atlantica subsp. kurdica is an endemic plant of iran which belongs to anacardiaceae family. it has various traditional uses including astringent and anti-diarrheal as well as improving some of the symptoms of gastrointestinal upsets. in this study we decided to investigate the effects of various fractions of baneh gum with different doses in an ...

background: brucella abortus is a gram-negative facultative intracellular bacterium that can cause a highly contagious disease in sheep, goats, cattle and one-humped camels. it is responsible for one of the most important zoonosis in human. the aim of this study was to evaluate the role of mentha piperita, origanum majorana, citrus lemon, cinnamomum verum and myristica fragrans essential volati...

a new approach for the synthesis of prussian blue nanoparticles using the cationic surfactant cetyl pyridinium chloride (cpc) as capping agent has been developed in the present work. powder x-ray diffraction, transmission electron microscopy, uv–vis absorption spectra, and ir spectroscopy were employed to characterize the product. the tem image showed that the prussian blue nanoparticles with d...

Problem statement: Fungal endophytes are widely studied for their potential as biocontrol agents towards fungal pathogens. In vitro assessments usually reveal their antibiosis and mycoparasitism nature, but little is understood regarding their production of volatile metabolites as mechanisms of antagonism. Approach: This study explored the potential of fungal endophytes in controlling the patho...

BACKGROUND Growing evidence suggests a protective effect of volatile anaesthetics in ischaemia-reperfusion (I/R)-injury, and the accumulation of neutrophils is a crucial event. Pro-inflammatory cytokines carrying the C-X-C-motif including interleukin-8 (IL-8) and CXC-ligand 1 (CXCL1) activate CXC receptor-1 (CXCR1; stimulated by IL-8), CXC receptor-2 (CXCR2; stimulated by IL-8 and CXCL1), or bo...

UNLABELLED The nitric oxide (NO)-cyclic guanosine monophosphate (cGMP) signal pathway plays an important role in anesthetic and analgesic effects. We sought to determine the involvement of inhibition of soluble guanylyl cyclase (sGC) in the anesthetic mechanism and site of action of volatile anesthetics. We examined the effect of intracerebroventricular (ICV) administration of methylene blue (M...
