Human beings harbor clusters of bacteria in different parts of the body, such as the surface or the deep layers of the skin, the mouth, the lungs, the intestine, the vagina, and all the surfaces exposed to the outer world. The majority of microbes resides in the gut, have a weighty influence on human physiology and nutrition and are vital for human life. There is growing evidence showing that the gut microbiota plays important roles in the maturation of the immune system and the protection against some infectious agents...

Genetic or nutritional deficiencies in 1 carbon and homocysteine (Hcy) metabolism elevate Hcy-thiolactone levels and are associated with cardiovascular and neurologic diseases. Hcy-thiolactone causes protein damage, cellular toxicity, and proatherogenic changes in gene expression in human cells and tissues. A polymorphic cardio-protective enzyme, paraoxonase 1 (PON1), hydrolyzes Hcy-thiolactone in vitro. However, whether Hcy-thiolactone hydrolysis is a physiologic function of the PON1 protein and whether polymorphisms in the PON1 gene affect Hcy-thiolactone levels in humans was unknown...

Severe alcoholic hepatitis (SAH) is a costly and worldwide public health issue with high morbidity and mortality. Specific effective treatments for SAH have yet to be established. The aim of the present article is to review the current knowledge of the pathogenesis, assessment, and treatment options in patients with SAH. To date, alcohol abstinence and enteral nutrition are the recommended first-line treatments. Although corticosteroids remain the preferred therapy for certain patients with a modified Maddrey discriminant function level greater than 54, they only improve short-term survival rates...

The body of work relating to the gut microbiota of fish is dwarfed by that on humans and mammals. However, it is a field that has had historical interest and has grown significantly along with the expansion of the aquaculture industry and developments in microbiome research. Research is now moving quickly in this field. Much recent focus has been on nutritional manipulation and modification of the gut microbiota to meet the needs of fish farming, while trying to maintain host health and welfare. However, the diversity amongst fish means that baseline data from wild fish and a clear understanding of the role that specific gut microbiota play is still lacking...

It is generally acknowledged that malnutrition is a propensity factor for secondary infections in different clinical situations (malnutrition-associated infections in hospitalized patients and malnourished children in developing countries). However, it is not clear how malnutrition might facilitate the development of opportunistic infections in human immunodeficiency virus (HIV)-negative patients without a definite etiology (disease or treatment) of impaired cell-mediated immune response. We report here on a case of Pneumocystis jirovecii pneumonia in an HIV-negative patient suffering from anorexia nervosa with extreme malnutrition, which had a favorable outcome despite the severity of her respiratory failure...

Professional organizations worldwide recommend exclusive human milk/breastfeeding for the first 6 months of life, and continued breastfeeding with appropriate complementary foods for 1 year or more. This article focuses on the importance of prenatal messaging and goal setting to ensure that mothers are able to optimize their milk supply during the critical window of opportunity in first 2 weeks after delivery. Research data in the United States indicate that the largest categories of why women stopped breastfeeding were for reasons related to milk supply or concerns that the infant was not getting enough nutrition or gaining enough weight...

Microalgae treated with blue light have potential for production of human nutrition supplement and biofuel due to their higher biomass productivity and favorable fatty acid composition. Chlorella vulgaris, Chlorella pyrenoidosa, Scenedesmus quadricauda and Scenedesmus obliquus are representative green microalgae which are widely reported for algal production. In this study, we provide a systematic investigation of the biomass productivity, photosynthetic pigments, chlorophyll fluorescence and fatty acid content of the four green microalgae...

OBJECTIVE: Although the "mouthwatering" to sight, smell, or thought of food is commonly accepted in food and nutrition research, the concept of mouthwatering and human salivary flow conditioning is not well accepted in salivary research. The objective of this study was to revisit whether human salivary flow could be classically conditioned to a previously neutral stimulus. DESIGN: Sour candy or a non-food control in opaque containers were presented to healthy participants (n = 8)...

Contrary to organic solvent-induced aggregation of Au nanoclusters (AuNCs), herein, we reported aggregation induced emission enhancement (AIEE) of AuNCs in an aqueous media through confinement of AuNCs by in situ formed Zn-MOF for detecting Zn2+ . Glutathione capped AuNCs (GSH-AuNCs) was synthesized through reduction of Au3+ by glutathione. Zn2+ could significantly enhance the fluorescence of GSH-AuNCs upon addition of 2-methylimidazole, which was attributed to the formation of Zn-MOF. XRD and TEM were used to characterize the in situ formed Zn-MOF...

Thirty years ago, Seymour 'Gig' Levine published a serendipitous, yet, seminal finding on the regulatory role of maternal presence on the corticosterone stress response of neonatal rats, during the developmental period know as stress hyporesponsive period. At the same time, his group of students also studied the stress response of infant monkeys to maternal separation, as a means to understand the stressful nature of disruptions of attachment to the primary caregiver. Gig and his group of students and collaborators, mainly in the USA and the Netherlands, investigated how initial social relationships buffer the stress response of non-human primate and rodent infants...

Mercury is a neurotoxin, its main source in the human organism being fish and seafood. The first level in the marine food web is formed of planktonic and benthic photosynthetic microorganisms, which form a biofilm on the surface of the hard bottom (epilithon) or plants (epiphyton). They are carriers of nutritional as well as toxic substances and pass these on to subsequent levels of the trophic web. Their biomass is often dominated by diatoms. This was the basis for the presented study into Hg accumulation in epilithic, epiphytic and planktonic diatoms, which was carried out in 2012-2013 in the coastal zone of the Puck Lagoon and the Gulf of Gdańsk (southern Baltic)...

The benefits of goat milk, fermented milks, and probiotics for the humans are well documented. In this study, a novel fermented goat milk was manufactured with the putative probiotic strain Lactobacillus plantarum C4 together with L. bulgaricus and Streptococcus thermophilus . Ultrafiltration was chosen as the skimmed milk concentration method because it produced the best viscosity and syneresis and a high casein content. The viability rate of all bacterial strains was >10⁷ cfu/mL, even after 5 weeks of storage or after in vitro gastrointestinal digestion, which is especially important for exertion of the probiotic strain functionalities...

A useful animal model of intestinal injury is pivotal for studying its pathogenesis and developing nutritional interventions (e.g., amino acid supplementation). Here, we propose the use of indomethacin (IDMT) to induce intestinal inflammation in neonatal pigs. Fourteen-day-old piglets fed a milk replacer diet receive intraperitoneal administration of IDMT (5 mg/kg body weight) for 3 consecutive days. On day 4, blood and intestinal samples are obtained for physiological and biochemical analyses. IDMT increases blood DAO activity, I-FABP concentration, neutrophil and eosinophil numbers; intestinal MMP3 mRNA levels, MPO activity, and MDA concentration; but reduces the plasma concentration of citrulline (synthesized exclusively by enterocytes of the small intestine), intestinal GSH-Px activity, and mRNA levels for villin , I-FABP , TRPV6 , AQP10 , and KCNJ13 ...

Farming and rural development are central to the diversity of global food systems and diets, both significant factors in determining the nutrition and health outcomes of the world's population. Diets are not static and indeed are changing due to globalization, urbanization and demographic shifts. In addition, multiple burdens of malnutrition (both undernutrition and overweight and obesity) are not improving fast enough and in some cases, reversing for the worse. Unhealthy diets are major contributors to these burdens...

The Italian Parliament has recently approved the Law n. 219/2017 concerning "Rules on informed consent and advance directives". The manuscript points out the main key points of the new law, in order to clarify the role of the advance directives and to provide clear operational guidelines for healthcare personnel. Taking into consideration the Italian deontological and juridical context, along with the main jurisprudential judgements, the law has been analysed. The Authors discussed the new rules and the bioethical issues also in relation to the provisions stated by the Convention on Human Rights and Biomedicine (Convention of Oviedo)...

The consumption of berries has been linked to decreased risk of degenerative disease. Berries are regularly processed into juices. It is largely unknown how the juicing process affects the bioavailability of metabolites. As metabolomics has shown to be a valuable nutritional tool to study global metabolite differences, the aim of this study was to investigate the effect of juicing on the relative appearance of blueberry metabolites in humans using metabolomics. Nine healthy subjects consumed 250 g of fresh blueberries either as the whole fruit or after juicing, and provided blood and urine samples before and 2 h after intake in a cross-over design...

A key strategy for attenuating the development of antimicrobial resistance (AMR) is ensuring judicious use of antimicrobials in human and veterinary medicine and in agriculture. Research on AMR in agriculture includes risk assessment, risk management, and identifying the role of agricultural practices in development of AMR. Risk assessment includes an impact assessment of antimicrobial use in livestock and on the environment; for example, many antimicrobials are excreted unchanged and thus reach the environment through manure application...

Nutrition and metabolism are known to influence chromatin biology and epigenetics through post-translational modifications, yet how this interaction influences genomic architecture and connects to gene expression is unknown. Here we consider, as a model, the metabolically-driven dynamics of H3K4me3, a histone methylation mark that is known to encode information about active transcription, cell identity, and tumor suppression. We analyze the genome-wide changes in H3K4me3 and gene expression in response to alterations in methionine availability in both normal mouse physiology and human cancer cells...

Starch is a major source of energy in the human diet and is consumed in diverse forms. Resistant starch (RS) escapes small intestinal digestion and is fermented in the colon by the resident microbiota, with beneficial impacts on colonic function and host health, but the impacts of the micro- and nanoscale structure of different physical forms of food starch on the broader microbial community have not been described previously. Here, we use a porcine in vitro fermentation model to establish that starch structure dramatically impacts microbiome composition, including the key amylolytic species, and markedly alters both digestion kinetics and fermentation outcomes...

World egg production and consumption have been increasing for the past decades. Traditional strategies in poultry nutrition have made vital contributions to this great growth in quantity. However, current global issues should be considered in modern egg production such as growing populations and food security, food safety and quality, limited resources and environmental problems. The development of knowledge of poultry nutrition and modern biotechnology provides novel nutritional approaches to closely fit the requirement of pullets and laying hens, which will consequently decrease the nutrition excretion and maintain the lower cost of feed...
