Urmia Lake is one of the two large hypersaline lakes in the world which have Artemia. It is located in northwest of Iran. Due to a decrease in water inflow and volume, the salinity of Urmia Lake has reached to more than 300 g.l-1 since 2001. The increased salinity has greatly influenced biological aspects of the lake, and caused the lake undergoes at critical conduction. The aim of the prese...

this study was intended to evaluate the quality of 30 honey samples, in terms of physicochemical properties such as moisture content, electrical conductivity, ash content, reducing sugars and sucrose, free acidity, ph, diastase activity, and hydroxymethylfurfural (hmf) content. moreover, three methods recommended by the international honey commission for the determination of hmf, including 1) h...

background: the prangos ferulacea (pf)–yogurt is a traditional food in iran. this study investigated the effects of pf on the microbial, physicochemical and sensory properties of probiotic yoghurt. methods: pasteurized low fat milk was heated up to 85°c, cooled to 40°c, and then mixed with conventional and lactobacillus casei starter cultures incubated at 37°c until ph decreased to 4.6. then, t...

saffron flower (crocus sativus) is one of the most precious spices in the world. in this respect, thesaffron style samples were gathered from the farms of torbat-heidariyeh located in south khorasanprovince during one year and their preparation was performed based on the common manufacturingstandards. then, in order to considering the international and national standards for saffron and spicese...

sour cherry is one of the most important horticultural products in iran that consumes as fresh and dried fruit. in this research the effect of osmotic pretreatment on physicochemical, antioxiative and microbial characteristics of 4 cultivars of sour cherry: early jibilium, butermo, sigany and local were investigated. the samples were placed in different osmotic solution, dried and vacuum packed...

The study evaluated the shelf life of buffalo meat in refrigerated storage. The shelf life was evaluated for 9 days where all the physicochemical parameters were analysed on alternate days i.e. on the 0th, 3rd, 5th, 7th and 9th days. Buffalo meat was kept in polystyrene foam trays which were covered with PVC film and stored at refrigeration temperature. A significant change was recorded in phys...

BACKGROUND Channels and pores in biomacromolecules (proteins, nucleic acids and their complexes) play significant biological roles, e.g., in molecular recognition and enzyme substrate specificity. RESULTS We present an advanced software tool entitled MOLE 2.0, which has been designed to analyze molecular channels and pores. Benchmark tests against other available software tools showed that MO...

Although it is agreed that physicochemical features of molecules determine their perceived odor, the rules governing this relationship remain unknown. A significant obstacle to such understanding is the high dimensionality of features describing both percepts and molecules. We applied a statistical method to reduce dimensionality in both odor percepts and physicochemical descriptors for a large...

Recent advancement in the pattern recognition field stimulates enormous interest in Protein Fold Recognition (PFR). PFR is considered as a crucial step towards protein structure prediction and drug design. Despite all the recent achievements, the PFR still remains as an unsolved issue in biological science and its prediction accuracy still remains unsatisfactory. Furthermore, the impact of usin...

This critical review examines in vitro and in vivo evidence for the influence of engineered nanomaterial (ENM) physicochemical properties on their distribution into, and effects on, the nervous system. Nervous system applications of ENMs; exposure routes and potential for uptake; the nervous system and its barriers to ENM uptake; and the mechanisms of uptake into the nervous system and overcomi...
