E operating in HS linearity conditions followed by GC×GC-TOF MS featuring tandem ionization gives the opportunity to improve the quality of analytical data and reliability of results.
For health reasons it is preferred to prepare food products with edible fats and oils that are high in unsaturated fatty acids. Unfortunately, these unsaturated acids are susceptible to lipid oxidation and the addition of natural antioxidants, e.g., rosemary extracts, etc. is needed.
To assess the efficacy of natural oxidation inhibition strategies, fast, yet realistic, and objective methods are needed to study oxidation inhibition.
A model system consisting of salt and sunflower oil is proposed as a model for dry soups and sauces. Hexanal formation is studied using fast GC-MS as a quantitative indicator for lipid oxidation.
A fast GC-MS method using a short, 6-m 150 µm inner-diameter column was developed that allowed elution of hexanal within approximately 20 s, with a total run time of 2 min. The GC method has quantification limits below 1 ppm and is hence much more sensitive than the human nose.
The new accelerated method with hexanal read-out was successfully applied in a study to identify spices and herbs mixtures that can act as natural inhibitors of lipid oxidation. The fast GC-MS method is extremely stable and allowed the analysis of thousands of samples with very little maintenance.
With the right mixture of spices and herbs, lipid oxidation can be delayed more than 100 times as compared to non-stabilized systems.

Genetic polymorphisms leading to variations in human milk oligosaccharide (HMO) composition have been reported. Alpha-Tetrasaccharide (A-tetra), an HMO, has been shown to only be present (>limit of detection; A-tetra+) in the human milk (HM) of women with blood type A, suggesting genetic origins determining the presence or absence (A-tetra-) of A-tetra in HM.
This study aimed to determine whether associations exist between HMO concentrations and cognitive development, and whether the associations vary between A-tetra+and A-tetra- groups in children (<25 months old).
We enrolled typically developing children (2-25 months old; mean, 10 months old) who were at least partially breastfed at the study visit. The Mullen Scales of Early Learning (MSEL) were used as the primary outcome measure to assess early cognitive development. Linear mixed effects models were employed by stratifying children based on A-tetra levels (A-tetra+or A-tetra-) to assess associations between age-removed HMO concentrations andrticularly language functions, in typically developing children who received HM containing detectable A-tetra during infancy.
Moderate acute malnutrition (MAM) affects 33million children annually. WH-4-023 mouse Investments in formulations of corn-soy blended flours and lipid-based nutrient supplements have effectively improved MAM recovery rates. Information costs and cost-effectiveness differences are still needed.
We assessed recovery and sustained recovery rates of MAM children receiving a supplementary food ready-to-use supplementary food (RUSF), corn soy whey blend with fortified vegetable oil (CSWB w/oil), or Super Cereal Plus with amylase (SC+A) compared to Corn Soy Blend Plus with fortified vegetable oil (CSB+w/oil). We also estimated differences in costs and cost effectiveness of each supplement.
In Sierra Leone, we randomly assigned 29 health centers to provide a supplement containing 550 kcal/d for ∼12 wk to 2691 children with MAM aged 6-59 mo. We calculated cost per enrollee, cost per child who recovered, and cost per child who sustained recovery each from 2 perspectives program perspective and caregiver perspective, combined.
s are necessary to estimate the full cost of MAM treatment. This trial was registered at clinicaltrials.gov as NCT03146897.
The 4 supplements performed similarly across recovery (but not sustained recovery) and costed measures. Analyses of posttreatment outcomes are necessary to estimate the full cost of MAM treatment. This trial was registered at clinicaltrials.gov as NCT03146897.
Vitamin D acts as a mediator in the immune system regulating antiviral mechanisms and inflammatory processes. Vitamin D insufficiency has been suggested as a potential risk factor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, although its impact on the prognosis of hospitalized patients with coronavirus disease 2019 (COVID-19) remains unclear.
This multicenter prospective cohort study was designed to investigate whether serum 25-hydroxyvitamin D [25(OH)D] concentration is associated with hospital length of stay and prognosis in hospitalized patients with COVID-19.
Patients with moderate to severe COVID-19 (n=220) were recruited from 2 hospitals in Sao Paulo, Brazil. Serum 25(OH)D concentrations were categorized as follows <10 ng/mL, 10 to <20 ng/mL, 20 to <30 ng/mL, and ≥30 ng/mL, and <10 ng/mL and ≥10 ng/mL. The primary outcome was hospital length of stay and the secondary outcomes were the rate of patients who required invasive mechanical ventilation and mortag/mL) exhibited a trend for longer hospital length of stay compared with patients with higher 25(OH)D concentrations. This association was not significant in the multivariable Cox regression model. Prospective studies should test whether correcting severe 25(OH)D deficiency could improve the prognosis of patients with COVID-19.
Insects have recently been identified as a more sustainable protein-dense food source and may represent a viable alternative to conventional animal-derived proteins.
We aimed to compare the impacts of ingesting lesser mealworm- and milk-derived protein on protein digestion and amino acid absorption kinetics, postprandial skeletal muscle protein synthesis rates, and the incorporation of dietary protein-derived amino acids into de novo muscle protein at rest and during recovery from exercise in vivo in humans.
In this double-blind randomized controlled trial, 24 healthy, young men ingested 30 g specifically produced, intrinsically l-[1-13C]-phenylalanine and l-[1-13C]-leucine labeled lesser mealworm- or milk-derived protein after a unilateral bout of resistance-type exercise. Primed continuous l-[ring-2H5]-phenylalanine, l-[ring-3,5-2H2]-tyrosine, and l-[1-13C]-leucine infusions were applied, with frequent collection of blood and muscle tissue samples.
A total of 73%±7% and 77%±7% of the lesser mealworm and milk protein-derived phenylalanine was released into the circulation during the 5 h postprandial period, respectively, with no significant differences between groups (P<0.
