BACKGROUND: As preterm infants do not experience the nutrient accretion and rapid growth phase of the third trimester of pregnancy, they are vulnerable to postnatal nutritional deficits, including of fat. Consequently, they require higher fat intakes compared to their full term counterparts to achieve adequate growth and development. Human milk fat provides the major energy needs of the preterm infant and also contributes to several metabolic and physiological functions. Although human milk has many benefits for this population, its fat content is highly variable and may be inadequate for their optimum growth and development...

<br>Background: The notion that exposure to chronic stress predisposes individuals to develop Type 2 diabetes (T2D) has gained much attention in recent decades. Long-term stress induces neuroadaptation in the amygdala and increases corticosterone levels. Corticosterone, the major stress hormone in rodents, induces insulin resistance and obesity in mice. However, little is known whether the stress-induced amygdalar neuroadaptation could promote the risk of T2D. METHODS: We used an 11-week high-fat-diet (HFD) feeding paradigm to induce insulin dysfunction in mice, followed by implementing a 10-day social defeat (SD) stress protocol...

RNA interference (RNAi) is one of the simplest and easiest methods for specifically perturbing gene function in an organism. In planarian research, RNAi is one of the essential methods for defining gene functions not only during regeneration, but also during other life history stages. Since the first report of the efficacy of RNAi in planarians in 1999, several RNAi protocols have been reported. Here, we describe protocols to synthesize and deliver synthetic double-stranded RNA (dsRNA) to planarians, either by injection or by feeding...

RNA interference (RNAi) is currently the only method available in planaria for assessing the function of particular genes. We describe here a method for performing body-wide gene knockdown, relying on dsRNA production in bacteria and subsequent delivery to planaria by feeding a liver-bacteria mixture. This method is ideal for screening many genes in parallel, in a cost-effective and reliable manner. We also describe a ligation-independent cloning strategy, which is used to rapidly transfer single genes into an RNAi vector that is also appropriate for downstream applications such as in situ hybridizations...

Patients suffering anorexia nervosa (AN) become anhedonic, in other words, unable or unwilling to derive normal pleasures and avoid rewarding outcomes, most profoundly in food intake. The neurobiological underpinnings of anhedonia are likely to involve mesolimbic reward circuitry. We propose here that this circuitry and its involvement in AN can be investigated using the activity-based anorexia (ABA) rodent model that recapitulates many of the characteristics of the human condition, most notably rapid weight loss...

Sublingual immunotherapy (SLIT) has been introduced as a noninvasive and safer approach for allergen-specific immunotherapies. In this study we investigated the efficacy of oral immunotherapy with recombinant Salsola kali 1 protein (Sal k 1) on Th1/Th2 balance in a mouse model of allergy. Female Balb/c mice were intraperitoneally sensitized with rSal k1, followed by a respiratory challenge with 1% (w/v) rSal k1. The sensitized mice were subjected to SLIT using rSal K1 expressing Lactobacillus lactis strain for three weeks...

BACKGROUND: Capacity development of health volunteers and text messaging to pregnant women through mobile phones have shown improved maternal and child health (MCH) outcomes and is associated with increased utilisation of MCH services. However, such interventions are uncommon in Nepal. We aim to carry out an intervention with the hypothesis that capacity building and text messaging intervention will increase the MCH service utilisation. METHOD/DESIGN: MATRI-SUMAN is a 12-month cluster randomized controlled trial (RCT)...

Using in vivo animal model systems for chemical screening can permit evaluation of the signaling pathways implicated. Xenopus laevis is an ideal model organism to test thyroid axis disruption as thyroid hormones are highly conserved across vertebrates. Here, we describe a high-throughput assay using non-feeding embryonic stage transgenic X. laevis (TH/bZip) to screen for thyroid disrupting chemicals using a 3 day exposure protocol. We further describe a protocol to detect endocrine disruption of thyroid axis by the analysis of gene expression using wild-type X...

The ability of thyroid hormone T3 to stimulate energy expenditure and regulate different aspects of whole body metabolism has been recognized for over a 100 years. Indeed in 1895 Adolf Magnus Levy was already describing the influence of the thyroid on setting the basal metabolic rate. Now it has been well characterized that the level of circulating T3 is correlated with energy expenditure both in humans and in rodent models (Mullur et al., Physiol Rev 94:355-382, 2014; Silva, Thyroid 5:481-492, 1995). Hypothyroidism and hyperthyroidism are respectively associated with low and high energy expenditure leading to high and low body mass index...

Golden cuttlefish (Sepia esculenta) is an important economic species in China. Because of the rapid decline of its natural resource, researchers are exploring breeding technique for this species. The major obstacle that hinders artificial breeding of S. esculenta is the low larvae survival rate. Mortality is especially high during the mouth-opening stage. Investigating the embryogenesis before the first feed could provide theoretical guidance for reproduction control and breeding of S. esculenta and other Sepia species...

Recent literature suggests that catalytic doses (&le;10 g/meal or 36 g/day) of D-fructose and D-allulose may reduce postprandial blood glucose responses to carbohydrate loads in people with and without type 2 diabetes by inducing glycogen synthesis. To assess the effect of small single doses of fructose and allulose on postprandial blood glucose regulation in response to a 75 g-oral glucose tolerance test (75 g-OGTT) in healthy individuals, we conducted an acute randomized, crossover, equivalence trial in healthy adults...

Serotonin exerts a modulating function on the development of the central nervous system, including hypothalamic circuits controlling feeding behavior and energy expenditure. Based on the developmental plasticity theory, early disturbances of synaptic availability of serotonin may promote phenotypic adaptations and late disorders of energy balance regulation leading to obesity and associated diseases. The aim of this systematic review is to determine the effects of pharmacological neonatal inhibition of serotonin reuptake by fluoxetine, on parameters related to feeding behavior and energy balance...

The performance of combined CO₂-sorbent/catalyst particles for sorption enhanced steam reforming (SESR), prepared via a simple mechanical mixing protocol, was studied using a spout-fluidised bed reactor capable of continuous solid fuel (biomass) feeding. The influence of particle size (300⁻500 and 710⁻1000 µm), CaO loading (60⁻100 wt %), Ni-loading (10⁻40 wt %) and presence of dicalcium silicate support (22.6 wt %) on SESR process performance were investigated. The combined particles were characterised by their density, porosity and CO₂ carrying capacity with the analysis by thermogravimetric analysis (TGA), Brunauer-Emmett-Teller (BET), Barrett-Joyner-Halenda (BJH) and mercury intrusion porosimetry (MIP)...

Congenital heart disease (CHD) is the most common neonatal congenital malformation. The variety and severity of clinical presentation depend on the cardiac structures involved and their functional impact. The management of newborns with CHD requires a multidisciplinary approach, in which the nutritional aspect plays an important role. An adequate caloric intake during either preand post-surgical period, in fact, improves the outcome of these patients. In addition, the failure to thrive of these children in childhood has been related to long-term cognitive delay (attention deficit disorders, aggressive behaviour and poor social and emotional development)...

The sugarbeet root maggot, Tetanops myopaeformis (von Röder) (Diptera: Ulidiidae), is a major pest of sugar beet Beta vulgaris L. (Carophyllales: Amaranthaceae)in the United States and Canada. Larval feeding on roots can reduce both stand and yield. Current management practices are heavily reliant on chemical control. However, the carbamate and organophosphate insecticides that are commonly used against T. myopaeformis are being phased out of use. Host plant resistance against this pest shows promise, but difficulties with maintaining T...
