Bran is a promising ingredient for nutritional fortification in starch-based dough systems. However its incorporation is a technological challenge favoring a shift in dough functionality. The objective of this study was to elucidate the impact of bran on baking performance independent of dough firmness and start of gelatinization. Therefore, corn starch was replaced by quinoa bran (10% to 50%) and water addition (80-110g/100g flour) was standardized on a fixed complex shear modulus (G*) and start of gelatinization (TOnset) based on a corn starch reference dough...

METHODS: Female Wistar rats were exposed to filtered air (F) or to concentrated fine particulate matter (P) for 15 days. After mating, the rats were divided into four groups and again exposed to F or P (FF, FP, PF, PP) beginning on day 6 of pregnancy. At embryonic day 19, the placenta was collected. The placental structure, the protein and gene expression of TGFβ1, VEGF-A, and its receptor Flk-1 and RAS were evaluated by indirect ELISA and quantitative real-time PCR. RESULTS: Exposure to P decreased the placental mass, size, and surface area as well as the TGFβ1, VEGF-A and Flk-1 content...

BACKGROUND: Intestinal iron is a nutritional compound, which is essential for enteric microbiota. We evaluated the hypothesis that polymorphisms which are known modifiers of intestinal iron uptake in adults are associated with necrotizing enterocolitis (NEC) in preterm infants. METHODS: Preterm infants (birth weight below 1,500 grams) were studied. Single nucleotide polymorphisms with known effects on serum iron levels (rs1800562, rs1799945, rs855791) were determined by polymerase chain reaction...

Since 2015, Society of Critical Care Medicine/American Society for Parenteral and Enteral Nutrition and Canadian critical care nutrition support guidelines have both been updated. Despite a similar evidentiary basis, there remain key differences between guideline recommendations. These differences in recommendations may pose confusion for the clinician and may encumber widespread applicability. The aim of this review was to enhance practitioner confidence in applying critical care nutrition support guidelines to patient care in their settings by outlining the similarities and differences between the American and Canadian methods for guideline development and describing the key differences and reasons behind the differences...

Tube feeding (TF) is the most common form of nutrition support. In recent years, TF administration has increased among patient populations within and outside hospital settings, in part due to greater insurance coverage, reduced use of parenteral nutrition, and improved formularies suitable for sole source nutrition. With increasing life expectancy and improved access to TFs, the number of adults dependent on enteral nutrition is expected to grow. However, enteral TF intolerance (ETFI) is the most common complication of TFs, typically presenting with at least 1 adverse gastrointestinal event, including nausea, diarrhea, and constipation...

Nutrient content claims (NCCs) may inflate perceived healthfulness of nutritionally poor foods. The aim of this study is to experimentally test the effects of NCCs on consumers' perceptions of fortified snack foods in terms of the presence of both healthful and less healthful nutrients, as well as their intentions to consume such products. It also explores the potential moderating effects of reading Nutrition Facts Labels (NFL) on the influence of NCCs. Data for this study were collected through a web-based experiment (N = 5,076)...

With the emerging interest in documenting and understanding muscle atrophy and function in critically ill patients and survivors, ultrasonography has transformational potential in measuring muscle quantity and quality. Here, we discuss the importance of quantifying skeletal muscle in the ICU setting. We also identify the merits and limitations of various modalities that are capable of accurately and precisely measuring muscularity. Ultrasound is emerging as a potentially powerful tool for skeletal muscle quantification; however, there are key challenges that need to be addressed in future work to ensure useful interpretation and comparability of results across diverse observational and interventional studies...

Pterin-containing natural products have diverse functions in life but an efficient and easy scheme for their in vitro synthesis is not available. Here, we report a chemo-enzymatic 14-step, one-pot synthesis that can be used to generate 13C- and 15N-labeled dihydrofolates (H2F) from glucose, guanine and p-aminobenzoyl-L-glutamic acid. This synthesis stands out from previous approaches to produce H2F in that the average yield of each step is >91% and it requires only one single purification step. The use of a one-pot reaction allowed us to overcome potential problems with individual steps during the synthesis...

Marine lipids, especially ω-3 polyunsaturated fatty acids (PUFAs) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have largely been linked to prevention of diet-induced diseases. The anti-inflammatory and hypolipidemic properties of EPA and DHA supplementation have been well-described. However, there is still a significant lack of information about their particular mechanism of action. Furthermore, repeated meta-analyses have not shown conclusive results in support of their beneficial health effects...

The effects of angiotensin-converting enzyme (ACE) inhibition by an antihypertensive drug, captopril, and milk casein-derived ACE-inhibiting bioactive tripeptide isoleucine-proline-proline (Ile-Pro-Pro), on local renin-angiotensin system (RAS) and glucocorticoid production in the intestine were studied in the dextran sodium sulfate induced colitis in mice. Mice received water or 3% dextran sodium sulfate with or without either 15.7 mg/l captopril or 833 mg/l Ile-Pro-Pro for 7 days. Captopril and Ile-Pro-Pro were found to have distinct effects on local renin-angiotensin system and mRNA expression of glucocorticoid synthesis components in colon in vitro...

Overcoming metabolic stress is a critical step in tumorigenesis. Acetyl coenzyme A (acetyl-CoA) converted from glucose or acetate is a substrate used for histone acetylation to regulate gene expression. However, how acetyl-CoA is produced under nutritional stress conditions is unclear. Herein we report that nutritional stress induces nuclear translocation of ACSS2 (acyl-CoA synthetase short-chain family member 2). This translocation is mediated by AMP-activated protein kinase (AMPK)-dependent ACSS2 Ser659 phosphorylation and subsequent exposure of the nuclear localization signal of ACSS2 to KPNA1/importin α5 for binding...

During the last years, phospholipids (PLs) have attracted great attention because of their crucial roles in providing nutritional values, technological and medical applications. There are considerable proofs that PLs have unique nutritional benefits on human health, such as reducing cholesterol absorption, improving liver functions, and decreasing the risk of cardiovascular diseases. PLs are the main structural lipid components of cell and organelle membranes in all living organisms, and therefore, they occur in all organisms and the derived food products...

The fungal lineage is one of the three large eukaryotic lineages that dominate terrestrial ecosystems. They share a common ancestor with animals in the eukaryotic supergroup Opisthokonta and have a deeper common ancestry with plants, yet several phenotypes, such as morphological, physiological, or nutritional traits, make them unique among all living organisms. This article provides an overview of some of the most important fungal traits, how they evolve, and what major genes and gene families contribute to their development...
