Impact of ultrasound processing parameters on physical characteristics of lycopene emulsion.

Using ultrasound technology for obtaining O/W lycopene emulsions needs analyzing the parameters for the enhanced application. To this end, O/W lycopene emulsions (30:70) were processed using ultrasound with powers of 240 W and 360 W in 5, 10, and 15 min. Afterward, the poly dispersity index, droplet size, ζ-potential, turbidity, phase separation, lycopene concentration, rheological behavior, surface tension, and morphology of emulsions was investigated.

Genetic analysis of freezing tolerance in camelina [Camelina sativa (L.) Crantz] by diallel cross of winter and spring biotypes.

Camelina [Camelina sativa (L.) Crantz] is a frost-tolerant oilseed plant that is cultivated as an autumn crop in semi-arid regions.

The Gene Family in : Genome-Wide Identification and Expression Analysis under Drought and Salinity Stresses.

Members of the / transcription factor family play critical roles in plant development, biosynthesis of key metabolites, and stress response. A detailed study was performed to identify ss in the durum wheat ( ssp. ) genome, which resulted in the identification of 271 genes distributed on chromosomes 1A-7B.

Extraction, Purification, and Characterization of Trypsin Obtained from the Digestive System of Yellowfin Seabream (Acanthopagrus latus).

The development of the marine aquaculture industry has led to the generation of significant amounts of fish wastes. Marine farm wastes exert adverse effects on the surrounding area of the cages. On the other hand, wastes of fish and other aquatic animals are regarded as major sources of valuable natural bioactive compounds, including enzymes, proteins, bioactive peptides, oil, amino acids, collagen, gelatin, calcium, biopolymers, and water-soluble minerals.

Preservation of gallic acid and methyl gallate on purified Kilka fish oil oxidation by Rancimat.

Kinetic analysis of gallic acid and methyl gallate in purified Kilka oil was studied in the concentration, range 200-1600 ppm, during autooxidation in Rancimat test at 60°C. The stabilization factor (F), the oxidation rate ratio (ORR), the activity (A), and the mean rate of antioxidant consumption (W) were determined. The scavenging activity of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals decreased in the order gallic acid > methyl gallate > α-tocopherol > BHT as observed in Kilka oil.

Exploiting Differential Gene Expression to Discover Ionic and Osmotic-Associated Transcripts in the Halophyte Grass .

Background: Salinity as a most significant environmental challenges affects the growth and productivity of plants worldwide. In this study, the ionic and iso-osmotic effects of salt stress were investigated in L., a halophyte grass species from Poaceae family, by cDNA-amplified fragment length polymorphism (cDNA-AFLP) technique.

Stabilizing corn oil using the lemon balm () antioxidants extracted by subcritical water.

This research was set up to identify the impact of the antioxidant compounds present in lemon balm extract (LBE) as obtained by the subcritical water (SBCW) method on the oxidative stability of corn oil. An extraction yield of 28.52% was obtained for the SBCW and rosmarinic acid was identified to be the predominant phenolic compound present in the LBE.

Genome-wide exploration of C2H2 zinc finger family in durum wheat (Triticum turgidum ssp. Durum): insights into the roles in biological processes especially stress response.

C2H2 type of zinc finger transcription factors (C2H2-ZFP TFs) play crucial roles in plant developments and stress response. Regarding its importance, genome-wide study of C2H2-ZFs were performed in multiple important plant species, but any such investigation was not fulfilled in Triticum turgidum ssp. Durum (durum wheat) as an important nutritional crop.

Differential Connectivity in Colorectal Cancer Gene Expression Network.

Background: Colorectal cancer (CRC) is one of the challenging types of cancers; thus, exploring effective biomarkers related to colorectal could lead to significant progresses toward the treatment of this disease.

Methods: In the present study, CRC gene expression datasets have been reanalyzed. Mutual differentially expressed genes across 294 normal mucosa and adjacent tumoral samples were then utilized in order to build two independent transcriptional regulatory networks.

Altering allergenicity of cow's milk by food processing for applications in infant formula.

Cow's milk-based infant formulas have a long tradition in infant nutrition, although some infants are unable to use them due to presence of several known allergens. Various processing methods have been identified capable of reducing cow's milk protein allergenicity including thermal and non-thermal methods and their combinations. Heat treatment and enzymatic hydrolysis have been in production of hypoallergenic infant formulas.

Assessment of DNA Contamination in RNA Samples Based on Ribosomal DNA.

One method extensively used for the quantification of gene expression changes and transcript abundances is reverse-transcription quantitative real-time PCR (RT-qPCR). It provides accurate, sensitive, reliable, and reproducible results. Several factors can affect the sensitivity and specificity of RT-qPCR.

Rheological and microstructural properties of beef sausage batter formulated with fish fillet mince.

Rheological properties and microstructure of beef meat sausage batter, incorporated with different percentages of fish fillet mince (5 %, 20 %, 35 % and 50 %), were investigated and compared to the control (0 % fish). By increasing the proportion of fish fillet mince to the sausage formula up to 35 % and 50 %, hardness was increased by 40 % and 16 %, respectively, (P < 0.05), whereas, cohesiveness and springiness showed no significant differences (P > 0.

Kolkhoung () Hull Oil and Kernel Oil as Antioxidative Vegetable Oils with High Oxidative Stability and Nutritional Value.
