Article Synopsis
  • The research identified monosaccharides as key building blocks for complex carbohydrates, focusing on 197 rice accessions' whole grain to quantify their content using a specific analytical technique (HPAEC-PAD).
  • A genome-wide association study (GWAS) was conducted, revealing 49 significant signals associated with monosaccharide contents tied to 17 genomic regions (quantitative trait loci) across seven chromosomes in rice.
  • The study linked specific candidate genes to the content of various monosaccharides (like fucose, mannose, and galactose), contributing to a deeper understanding of the genetic mechanisms that regulate monosaccharide biosynthesis, potentially enhancing the nutritional quality of rice.

Anthocyanin pigment as a phenolic secondary metabolite is accumulated in areal organs of some rice cultivars. Despite several research attempts, the majority of genomic regions and candidate genes for purple-colored stem (Ps) resulting from anthocyanin pigmentation of rice leaf sheath have not been identified. A genome-wide association study (GWAS) and whole-genome resequencing (WGR) analysis was applied for genetic dissection of anthocyanin pigmentation of rice stem.

Article Synopsis
  • * A study was conducted using female Wistar rats divided into four groups to observe the effects of miR-149-5p mimic on various indicators of cerebral ischemia and BB permeability, including neurological defects and edema.
  • * Results showed that after cerebral ischemia, miR-149-5p levels decreased, but treatment with its mimic led to increased expression of tight junction proteins (Occludin and ZO-1) and decreased Calpain levels and BBB permeability, suggesting a

Article Synopsis
  • Cellulose and lignin are key components of rice straw that affect its quality for industrial use, particularly in the production of fermentable sugars.
  • A genome-wide association study involving 33,484 SNPs analyzed rice genotypes to find genetic variability related to cellulose, lignin, and sugar content in rice straw.
  • Significant genomic regions linked to these traits were identified, shedding light on candidate genes involved in cell wall metabolism, which could help enhance the understanding of rice straw's biochemical properties.

Optimized stacking, a new method for constructing ensemble surrogate models applied to DNAPL-contaminated aquifer remediation.

J Contam Hydrol

December 2021

Civil, Water and Environmental Engineering Faculty, Shahid Beheshti Univ., P.O. Box 16765-1719, Bahar Blvd., Hakimieh, Tehran 1658953571, Iran. Electronic address:

Surfactant-enhanced aquifer remediation (SEAR) is an appropriate method for DNAPL-contaminated aquifer remediation; However, due to the high cost of the SEAR method, finding the optimal remediation scenario is usually essential. Embedding numerical simulation models of DNAPL remediation within the optimization routines are computationally expensive, and in this situation, using surrogate models instead of numerical models is a proper alternative. Ensemble methods are also utilized to enhance the accuracy of surrogate models, and in this study, the Stacking ensemble method was applied and compared with conventional methods.

This study was aimed to develop a novel nanocarrier for coenzyme Q10 (CoQ10) by a green process that prevented the use of surfactants and organic solvents. Triglyceride/phospholipid-based nanocarriers were developed through high-pressure homogenization (an industrial feasible process), and a 2 fractional factorial design was adopted to assess the influences of formulation variables on the considered responses, including vesicle size, entrapment efficiency, loading capacity, and solubility of the vehicles in simulated gastrointestinal fluids. The optimized formulation was further in-depth characterized in terms of morphology, release behavior, biocompatibility (Caco-2 cell cytotoxicity and histological examination), thermal behavior, and Fourier transform infrared analysis.

Sheep Milk: Physicochemical Characteristics and Relevance for Functional Food Development.

Compr Rev Food Sci Food Saf

March 2017

Inst. Federal de Educação, Ciência e Tecnologia do Rio de Janeiro, Depto. de Alimentos, 20270-021, Rio de Janeiro, Brazil.

Sheep milk has a high nutritional value and high concentrations of proteins, fats, minerals, and vitamins, as compared to the milks of other domestic species. The physicochemical and nutritional characteristics of sheep milk can be advantageous for the manufacture of products containing prebiotic ingredients and/or probiotic bacteria, which are major categories in the functional food market. Following this technological trend, this review will address the characteristics and advantages of sheep milk as a potentially functional food, as well as the development of sheep milk dairy products containing prebiotics and/or probiotics.

Cytoplasmic male sterility (CMS) is a cornerstone of hybrid production in many crops. In three-line hybrid systems, use of CMS, maintainer, and fertility restorer lines is necessary for production of hybrid seeds. Limited resources of CMS and low variation of CMS lines cause genetic vulnerability to pathogens.

Experimental design and desirability function approach for development of novel anticancer nanocarrier delivery systems.

Pharmazie

January 2011

Department of Chemical Engineering, Medicinal Plants and Drugs Research Institute, Shahid Beheshti Univ., G.C., Evin, Tehran, Iran.

The therapeutic effects of anticancer drugs would highly improve if problems with low water solubility and toxic adverse reactions could be solved. In this work, a full factorial experimental design was used to develop a polymeric nanoparticulate delivery system as an alternative technique for anticancer drug delivery. Nanoparticles containing tamoxifen citrate were prepared and characterized using an O/W emulsification-solvent evaporation technique and different analytical methods.
