Properties of Brazil nuts: A review
Brazil nut is a seed with high nutritional value and of great economic importance to the Northern region of Brazil. In addition to enabling direct consumption, its nutritional potential enables the development of various products. Among its nutrients, emphasis is given to the amino acid-rich proteins, lipid content and selenium, which exhibits antioxidant properties. This review addresses the nutritional...

Rapid analysis for the identification of the seagrass Halophila ovalis (Hydrocharitaceae)
Seagrasses are considered as one of the most important species as they play key ecological roles in various types of ecosystems and also provide a food source for endangered animal species. There are two main characteristics of seagrasses that hinder efforts to correctly identify species based on conventional identification keys alone: i) the variability of morphological characteristics and ii) lack of needed...

Optimization of explants surface sterilization condition for field grown peach (Prunus persica L. Batsch. Cv. Garnem) intended for in vitro culture
The aim of this work was to sterilize nodal explants, so as to mitigate microbial contamination in peach micropropagation. The nodal explants were treated with three concentrations levels (0.15, 0.25 and 0.5% (w/v) active ingredient of chlorine) of locally produced bleach, sodium hypochlorite (NaOCl) for varying exposure times (10, 15 and 20 min). These treatments were carried out in randomized complete...

Biodegradation of polycyclic aromatic hydrocarbons (PAHs) in spent and fresh cutting fluids contaminated soils by Pleurotus pulmonarius (Fries). Quelet and Pleurotus ostreatus (Jacq.) Fr. P. Kumm
The potential of Pleurotus pulmonarius and Pleurotus ostreatus on the degradation of PAHs in spent and fresh cutting fluids (SCF and FCF) contaminated soils was investigated. Different weights of soil samples were contaminated with varying composition (10, 20 or 30%) of spent and fresh cutting fluids separately then inoculated each sample with P. pulmonarius and P. ostreatus separately and incubated at 28 ±...

Production and antagonistic effect of Trichoderma spp. on pathogenic microorganisms (Botrytis cinerea, Fusarium oxysporium, Macrophomina phasealina and Rhizoctonia solani)
Trichoderma spp. are widely used as bio-fungicides in agriculture. Induction of plant defense and mycoparasitism (killing of one fungus by another) are considered to be the most important mechanisms of Trichoderma-mediated biological control. This study is based on the optimized production of Trichoderma viride. The media used for the economical production of T. viride conidia contain 5% jaggery and 0.5%...

Nutritional composition, phytochemicals and microbiological quality of the legume, Mucuna pruriens
The aim of this study was to evaluate the nutritional and phytochemical compositions and microbiological quality of seeds of the legume Mucuna pruriens (MP) grown in northeastern Brazil. MP flour and extract were produced and evaluated for proximate, mineral, and phytochemical compositions, fatty acid profile, and microbiological quality. MP flour and seed extract showed 43.12 and 43.4% of protein, 7 and 7.6% lipid...

Nutritional, antinutritional and phytochemical status of okra leaves (Abelmoschus esculentus) subjected to different processes
The aim of this study was to analyze the nutritional quality and antinutritional factors of okra leaves subjected to different process. Proximate composition, calcium, magnesium, potassium were determined, as well as lectin, tannin, saponin and total phenolic compounds. The okra leaves showed a predominance of carbohydrates, fibers and proteins that were not significantly affected by process, being also considered...

Effects of ethanolic extract of garlic, roselle and ginger on quality attributes of chicken patties
Efficiency of ethanolic extracts of garlic, ginger and roselle on quality attributes of chicken patties was investigated. Sensorial qualities were evaluated using a 9-point hedonic scale. Lipid oxidation was assessed by monitoring malondialdehyde formation with 2-thiobarbituric acid (TBARS) assay. Total plate count (log10CFU/g) and Warmed Over Flavour (WOF) were determined on days 0, 7 and 14 of refrigerated...

Effect of methotrexate combined with ginger, silymarin or propolis on the mRNA expression levels of cytochrome P450 oxidoreductase (POR), caspase 3 (CASP-3) and interlukin 6 (IL-6)
The present study was performed to evaluate the effect of three natural antioxidants on the adverse effect of methotrexate (MTX) in normal liver cells. TaqMan RT-PCR technology was used to estimate the mRNA expression levels for three genes after rats injection with a single dose of 20 mg/kg b.w MTX or the same MTX dose combined with ginger, silymarin or propolis oral administration. The doses of ginger,...

Characterisation of botanical starches as potential substitutes of agar in tissue culture media
Seven botanical starches; cassava, sweet potato, Irish potato, maize, rice, wheat and sorghum were characterized to determine physicochemical properties influencing gel formation for preparation of tissue culture media. Total starch, protein, fat, amylose content, swelling power and pH were determined using acid hydrolysis, enzymic and spectrophotmetric methods. Each type of starch was tested for ability to...

Polymorphism of glucagon-like peptide-1 receptor gene (rs1042044) is associated with bone mineral density in Chinese Han postmenopausal women
Previous investigations indicated that glucagon-like peptide-1 (GLP-1) played important roles in bone turnover via GLP-1 receptors (GLP1Rs) in postmenopausal state. Furthermore, polymorphisms in GLP1R gene were suggested to affect the function of GLP1Rs and be associated with many diseases. However, the relationships between GLP1R polymorphisms and osteoporosis susceptibility and bone strength remain...
