BACKGROUND: Fingermarks are one of the most important and useful forms of physical evidence in forensic investigations. However, latent fingermarks are not directly visible, but can be visualized due to the presence of other residues (such as inorganic salts, proteins, polypeptides, enzymes and human metabolites) which can be detected or recognized through various strategies. Convenient and rapid techniques are still needed to provide obvious contrast between the background and the fingermark ridges and to then visualize latent fingermark with a high degree of selectivity and sensitivity...

A major cause of cardiovascular diseases and cancer is diet content, so the optimization of micronutrients in food is very important. Omega-3 fatty acids supplementation for patients had beneficial effects on subjective global assessment score and metabolic profiles. Fatty acids content and the metal ions in different seeds (e.g. linseed, poppy, grape, hemp, nuts, pumpkin, sesame, watermelon, chia) recommended as food supplements, purchased on the Romanian market, were compared. Gas chromatography coupled to mass spectrometry (GC-MS) was used as an excellent technique for fatty acids identification and quantitation, and inductively coupled plasma mass spectrometer (ICP-MS) for analytical measurements of metals...

We demonstrate experimentally for the first time a ~40-µJ two-octave-wide passively carrier-envelope phase (CEP)-stable parametric front-end for seeding an ytterbium (Yb)-pump-based, few-optical-cycle, high-energy optical parametric waveform synthesizer. The system includes a CEP-stable white-light continuum and two-channel optical parametric chirped pulse amplifiers (OPCPAs) in the near- and mid-infrared spectral regions spanning altogether a two-octave-wide spectrum driven by a regenerative amplifier. The output pulses are compressed and fully characterized to demonstrate the well-behaved spectral phase of this seed source...

A method was developed for the determination of atropine and scopolamine in buckwheat and related products. A modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) extraction procedure was evaluated. Dispersive solid phase extraction (d-SPE) was studied as clean-up step, using graphitized black carbon (GBC) and primary secondary amine (PSA). The extract was diluted with water (50:50, v/v) prior to chromatographic analysis. The method was validated and recoveries (except chia samples spiked at 10μg/kg) ranged from 75% to 92%...

BACKGROUND: Chia (Salvia hispanica L.) seeds have been described as a good source of lipids, protein, dietary fiber, polyphenolic compounds and omega-3 polyunsaturated fatty acids. The consumption of chia seed oil helps to improve biological markers related to metabolic syndrome diseases. The oil yield and fatty acids composition of chia oil is affected by several factors such as pre-treatment method and size reduction practices. Therefore, the main mandate of present investigate was to study the effect of different seed pre-treatments on yield, fatty acids composition and sensory acceptability of chia oil at different storage intervals and conditions...

Mucilage (M) and soluble protein (SP) extracted from chia seed and flaxseed were used as encapsulating material for two probiotic bacteria: Bifidobacterium infantis and Lactobacillus plantarum by spray drying. Probiotic survival and viability after spray drying and during storage were evaluated. B. infantis and L. plantarum displayed high survival (⩾98%) after encapsulation with mixtures of maltodextrin (MD) combined with M and SP from flaxseed (MD:FM:FSP - 7.5:0.2:7.5%, w/w/w) and chia seed (MD:CM:CSP - 7...

PURPOSE: Rats fed a long-term sucrose-rich diet (SRD) developed adipose tissue dysfunction. In the adipose tissue of these SRD-fed rats, the present study analyzed the possible beneficial effects of dietary Salba (chia) seeds in improving or reversing the depletion of antioxidant defenses, changes in pro-inflammatory cytokines and ROS production. METHODS: Wistar rats were fed a SRD for 3 months. After that, half of the animals continued with the SRD until month 6, while in the other half, corn oil was replaced by chia seeds for 3 months (SRD + chia)...

Mungbean (Vigna radiata (L.) Wilczek) is an important rotation legume crop for human nutrition in Asia. Bruchids (Callosobruchus spp.) currently cause heavy damage as pests of grain legumes during storage. We used omics-related technologies to study the mechanisms of bruchid resistance in seeds of the nearly isogenic lines VC1973A (bruchid-susceptible) and VC6089A (bruchid-resistant). A total of 399 differentially expressed genes (DEGs) were identified between the two lines by transcriptome sequencing. Among these DEGs, 251 exhibited high expression levels and 148 expressed low expression levels in seeds of VC6089A...

BACKGROUND: Chia seeds (Salvia hispanica L.) are considered a promising ingredient for the development of functional products, due to its high nutritional value: 343 g Kg(-1) of lipids, 251 g Kg(-1) proteins and 226 g Kg(-1) fibre. Considering chia's technological capacities, mainly the ability to swell when absorbing water and gel forming properties, its addition to a food matrix can affect texture and rheological behaviour, acting as texturing and stabilizing agent. The present work intends to assess the gelling properties of chia flour through the rheological characterisation of 100, 130 and 150 g Kg(-1) chia flour gels...

: Cardiac extracellular matrix (cECM) scaffolds are promising biomaterials for reconstructive surgery applications since they possess the structure/function properties of native tissue. Production of cECM scaffolds has been achieved using decellularization approaches, which commonly employ denaturing detergents, such as sodium dodecyl sulfate (SDS). Our antigen removal (AR) method has been shown to remove cellular and nonmyocyte components, while preserving cECM scaffold structure/function relationships...

The ancient grain is becoming enormously popular in modern food regimen in many countries; the higher proportion of α-linolenic acid makes chia the superb source of omega-3 fatty (about 65 % of the oil content). Omega-3 fatty acid has been associated with a large number of physiological functions in human body. Chia seed is a potential source of antioxidants with the presence of chlorogenic acid, caffeic acid, myricetin, quercetin, and kaempferol which are believed to have cardiac, hepatic protective effects, anti-ageing and anti-carcinogenic characteristics...

Distant organ metastasis of prostate cancer is a puzzle, and various theories have successively arisen to explain the mechanism of lethal cancer progression. While perhaps agreeable to many cancer biologists, the very statement of "seed and soil" proposed by Stephan Paget in 1881 is arguably still the major statement for organ-specific cancer metastasis. Since recent studies showed important correlations of regulation of cancer cells and the microenvironment, exosomes from cancer and stromal cells seem to create another important niche for metastasis...

SCOPE: There is few information about the possible health effects of a food combination based on a prehispanic Mexican diet (PMD). This diet rich in fiber, polyphenols, a healthy ratio of omega 6/omega 3 fatty acids, and vegetable protein could improve carbohydrate and lipid metabolism, gut microbiota and cognitive function. METHODS AND RESULTS: We examined the effect of a PMD in a sucrose enriched high-fat model. The PMD contains corn, beans, tomato, nopal, chia and pumpkin seeds in dehydrated form...
