Role of Maternal Dietary Protein and Amino Acids on Fetal Programming, Early Neonatal Development, and Lactation in Swine

Simple Summary Dietary protein is an important nutrient source for sows, necessary for not only growth and production, but also other physiological functions. Protein limitations in maternal diets have the potential to impair fetal myogenesis, while excess maternal dietary protein appears to only have minor effects on early fetal muscle formation. Effects of maternal protein deficiency on increased fat deposition in porcine neonates is inconsistent with gene expressions in the neonates. Sufficient maternal dietary protein can enhance porcine milk protein and fat concentration. Understanding the function of protein and amino acids in sows and the effects on their offspring can provide rational approaches for the regulation of piglet growth and further improvements in meat quality in the future. Abstract Maternal nutrition plays a vital role in fetal development, early development of neonates, and lactation and regulates the lifetime productivity of offspring. During pregnancy, maternal nutrition alters expression of the fetal genome and the development of tissues and organs via fetal programming. After parturition, maternal nutrition continues to regulate growth and development of piglets through maternal milk, which contains carbohydrates, lipids, proteins and oligosaccharides. Thus, deficiencies in maternal nutrition are detrimental to development of piglets, which can lead to inefficient growth and decreased carcass merit. Protein is an important nutritional component for sows, which not only functions in muscle development, but also plays a vital role in embryonic and neonatal development and lactation. Although effects of maternal undernutrition on neonatal development have been widely studied in sows, the function of different maternal dietary protein levels on fetal development, neonatal growth and lactation performance of sows is largely unknown. Determination of the effects and underlying mechanisms of maternal dietary protein levels on development of piglets is vital to the pork industry. Therefore, we summarized recent reports regarding mechanisms of effects of maternal protein levels on regulation of conceptus growth and early postnatal development though uterine fetal programming and lactation in swine.

Effects of an immunomodulatory feed additive on body weight, production parameters, blood metabolites, and health in multiparous transition Holstein cows.

The study investigated the impact of feeding OmniGen-AF® (OG; Phibro Animal Health, Quincy, IL) from dry-off to week 4 of lactation at two doses on production performance and metabolic adaptation of multiparous Holstein cows. Forty-eight cows were blocked and assigned randomly to three treatments: OG was fed at 0 g/head/day (CON), 60 g/head/day (OG60), or 90 g/head/day (OG90). No difference was observed in dry matter intake (DMI) throughout the experiment, whereas feeding OG tended to decrease the percentage body weight change (PWC) on week 2. Although colostrum yield was not affected by treatment, colostrum IgG production of OG90 tended to be higher than that of CON. OG supplementation did not affect overall milking performance but decreased milk SCC during the first 4 weeks of lactation. In prepartum, OG supplementation decreased the concentrations of serum albumin and calcium, and increased serum globulin. OG supplementation tended to increase serum total protein, globulin, and calcium contents postpartum. Furthermore, reduced incidence of mastitis and udder edema were observed. In conclusion, supplementing cows with OG from dry-off period reduces or modulates the inflammation responses associated with parturition, potentially resulting in improved postpartum health, while feeding OG more than 60 g/head/day did not warrant further benefits.
Ocean warming combined with lower omega-3 nutritional availability impairs the cardio-respiratory function of a marine fish

ABSTRACT Highly unsaturated fatty acids of the omega-3 series (HUFA) are major constituents of cell membranes, yet are poorly synthesised de novo by consumers. Their production, mainly supported by aquatic microalgae, has been decreasing with global change. The consequences of such reductions may be profound for ectotherm consumers, as temperature tightly regulates the HUFA content in cell membranes, maintaining their functionality. Integrating individual, tissue and molecular approaches, we examined the consequences of the combined effects of temperature and HUFA depletion on the key cardio-respiratory functions of the golden grey mullet, an ectotherm grazer of high ecological importance. For 4 months, fish were exposed to two contrasting HUFA diets [4.8% eicosapentaenoic acid (EPA)+docosahexaenoic acid (DHA) on dry matter (DM) versus 0.2% EPA+DHA on DM] at 12 and 20°C. Ventricular force development coupled with gene expression profiles measured on cardiac muscle suggest that combining HUFA depletion with warmer temperatures leads to: (1) a proliferation of sarcolemmal and sarcoplasmic reticulum Ca2+ channels and (2) a higher force-generating ability by increasing extracellular Ca2+ influx via sarcolemmal channels when the heart has to sustain excessive effort due to stress and/or exercise. At the individual scale, these responses were associated with a greater aerobic scope, maximum metabolic rate and net cost of locomotion, suggesting the higher energy cost of this strategy. This impaired cardiac performance could have wider consequences for other physiological performance such as growth, reproduction or migration, all of which greatly depend on heart function. Summary: The synergistic effects of rising sea temperature and reduced omega-3 food content impair cardiac function of a key ecological fish species, at individual, cellular and individual levels.
ERK Activity Dynamics during Zebrafish Embryonic Development

During vertebrate development, extracellular signal-regulated kinase (ERK) is activated by growth factors such as fibroblast growth factor (FGF), and it regulates the formation of tissues/organs including eyes, brains, somites, limbs, and inner ears. However, an experimental system to monitor ERK activity dynamics in the entire body of the vertebrate embryo is lacking. We recently studied ERK activity dynamics in the pre-somitic mesoderm of living zebrafish embryos injected with mRNAs encoding a Förster resonance energy transfer (FRET)-based ERK biosensor. In this study, transgenic zebrafish stably and ubiquitously expressing the ERK biosensor were generated to monitor ERK activity dynamics throughout embryonic development. The system allowed the identification of ERK activation domains in embryos from the late blastula to the late segmentation stage, consistent with immunostaining patterns obtained using anti-phosphorylated ERK antibody. A spatiotemporal map of ERK activity in the entire body during zebrafish embryogenesis was generated, and previously unidentified activation dynamics and ERK domains were identified. The proposed system is the first reported method to monitor ERK activity dynamics during vertebrate embryogenesis, providing insight into the role of ERK activity in normal and abnormal development in living vertebrate embryos.
Novel Long-Acting GLP-2 Analogue, FE 203799 (Apraglutide), Enhances Adaptation and Linear Intestinal Growth in a Neonatal Piglet Model of Short Bowel Syndrome with Total Resection of the Ileum.

BACKGROUND Glucagon-like peptide-2 (GLP-2) is an intestinotrophic factor released from L-cells in the ileum, a segment commonly resected or atretic in neonatal short bowel syndrome (SBS). In piglets, ileal resection decreases intestinal adaptation and endogenous GLP-2 production, whereas exogenous replacement promotes adaptation. In this study, we determined the effect of a novel long-acting GLP-2 analogue, FE 203799 (FE; apraglutide), upon intestinal growth, adaptation, and function in neonatal SBS piglets without ileum. METHODS Neonatal piglets were randomized to saline (n = 10) vs FE treatment (n = 8). All piglets underwent 75% intestinal resection with jejunocolic anastomosis and were pair-fed parenteral and enteral nutrition. Saline and FE (5 mg/kg) treatments were administered subcutaneously on days 0 and 4. On day 6, 24-hour fecal samples were collected for subsequent nutrient analysis. On day 7, small-intestinal length and weight were measured and tissue collected for analyses. RESULTS On day 7, saline and FE-treated piglets were healthy and gained equivalent weight (P = 0.12). Compared with saline piglets, FE-treated piglets had lower fecal fat (P = 0.043) and energy (P = 0.043) losses and exhibited intestinal lengthening (P = 0.001), greater small-intestinal weight (P = 0.004), longer villus height (P = 0.027), and greater crypt depth (P = 0.054). CONCLUSIONS The subcutaneous GLP-2 analogue, FE, enhanced intestinal adaptation in a neonatal model of SBS without ileum. The observed intestinal lengthening with FE treatment was unique compared with our prior experience with native GLP-2 in this same model and has important clinical implications for treating neonatal SBS. At this developmental stage, growth in the intestine, if augmented, could accelerate weaning from parenteral nutrition.
EEG-Based Spatio–Temporal Convolutional Neural Network for Driver Fatigue Evaluation

Driver fatigue evaluation is of great importance for traffic safety and many intricate factors would exacerbate the difficulty. In this paper, based on the spatial–temporal structure of multichannel electroencephalogram (EEG) signals, we develop a novel EEG-based spatial–temporal convolutional neural network (ESTCNN) to detect driver fatigue. First, we introduce the core block to extract temporal dependencies from EEG signals. Then, we employ dense layers to fuse spatial features and realize classification. The developed network could automatically learn valid features from EEG signals, which outperforms the classical two-step machine learning algorithms. Importantly, we carry out fatigue driving experiments to collect EEG signals from eight subjects being alert and fatigue states. Using 2800 samples under within-subject splitting, we compare the effectiveness of ESTCNN with eight competitive methods. The results indicate that ESTCNN fulfills a better classification accuracy of 97.37% than these compared methods. Furthermore, the spatial–temporal structure of this framework advantages in computational efficiency and reference time, which allows further implementations in the brain–computer interface online systems.
Clinical outcomes from early use of digoxin-specific antibodies versus observation in chronic digoxin poisoning (ATOM-4)

Abstract Introduction: In our previous study on chronic digoxin poisoning, there was a minor improvement after treatment with digoxin-specific antibody (digoxin-Fab). We hypothesised patients with elevated digoxin concentrations may derive little benefit from digoxin-Fab because their presenting complaint was more closely related to their multiple co-morbidities. We aimed to compare the outcome of patients who were initially treated with digoxin-Fab with those that received supportive care. Method: Patients were prospectively recruited to the study if they had an elevated digoxin concentration, signs or symptoms of toxicity thought to be from digoxin. Patients who were initially managed with digoxin-Fab were compared with those not initially receiving digoxin-Fab (observation group). Patients presented with ventricular arrhythmias before initial assessment were excluded from the analysis. Primary outcome was mortality. Secondary outcomes were length of stay (LOS), change in heart rate (HR) and potassium concentration. Results: From September 2013 to January 2018, 128 patients were recruited of which 78 (61%) received initial digoxin-Fab. Digoxin-Fab and supportive care groups had an initial median heart rate of 46 (range: 20–120) vs 52 bpm (range: 29–91) (p = .06), systolic blood pressure of 110 mmHg (range: 65–180) vs 125 mmHg (range: 90–184) (p = .009), respectively. Digoxin concentrations 4.4 nmol/L (range: 3.3–9) vs 4.2 (range: 2–11.2) (p = .42) and potassium concentrations 5.4 mmol/L (range: 3–11) vs 5.1 mmol/L (range: 3.5–8.2) (p = .33) were similar. Median dose of digoxin-Fab used was 1.5 vials (IQR: 1–2). There were 9 (12%) deaths in the Fab group compared to 7 (14%) in those treated with supportive care (risk difference −2.5%; 95% CI: −14 to 9%; p = .68). The median LOS was six days in both groups. Mean changes in potassium concentration [−0.5 ± 0.1 vs. −0.4 ± 0.1 mmol/L; difference −0.1 (95% CI: −.02, 0.4), p = . 70] and HR within 4 h [8 ± 1 vs. 7 ± 3 bpm; difference −1.0 (95% CI: −6.7, 4.8), p = 0.74] were similar in the two groups. Conclusions: This study did not appear to show any benefit from the routine use of digoxin-Fab in patients thought to have chronic digoxin poisoning. These patients have multiple co-morbidities that may be contributing to their clinical features, other treatments are often equally effective.
Nutraceutical and Medicinal Potential of the Morus Species in Metabolic Dysfunctions

Many populations use medicinal plants as a therapeutic treatment, due to their lower cost and greater access. Among the plant species used for medicinal purposes are those of the genus Morus. The most known species are Morus alba, rubra, and nigra. This review aims to collect data from the literature, predominantly from cell and animal studies, which presents a possible nutraceutical and medicinal potential of the species Morus for use in metabolic dysfunctions. The fruits and leaves of mulberry are used for therapeutic purposes. For scientific confirmation of these effects, they were studied for laxative properties, antibacterial activity, anti-atherogenic activity, and hepatoprotective function. Furthermore, the genus Morus is recognized for the treatment and prevention of diabetes mellitus, through its hypoglycemic action. It may also provide health benefits through immunomodulatory, anti-inflammatory, and anti-nociceptive effects. It has been found that the Morus species have phenolic compounds, flavonoids, and anthocyanins that act as important antioxidants and promote beneficial effects on human health. These phytochemical compounds differ among species. Blackberry (Morus nigra) are rich in flavonoids, while the white mulberry (Morus alba) has low concentrations of flavonoids and anthocyanins. In addition, another important factor is to ensure a complete exemption of toxic risks in the use of medicinal plants for the treatment of diseases. Studies have shown no toxic effects by the administration of extracts of Morus species. Thus, the mulberry tree presents nutraceutical potential. It is therefore a promising alternative for medicinal products based on medicinal plants.
Synergy between RecBCD subunits is essential for efficient DNA unwinding

The subunits of the bacterial RecBCD act in coordination, rapidly and processively unwinding DNA at the site of a double strand break. RecBCD is able to displace DNA-binding proteins, suggesting that it generates high forces, but the specific role of each subunit in the force generation is unclear. Here, we present a novel optical tweezers assay that allows monitoring the activity of RecBCD’s individual subunits, when they are part of an intact full complex. We show that RecBCD and its subunits are able to generate forces up to 25–40 pN without a significant effect on their velocity. Moreover, the isolated RecD translocates fast but is a weak helicase with limited processivity. Experiments at a broad range of [ATP] and forces suggest that RecD unwinds DNA as a Brownian ratchet, rectified by ATP binding, and that the presence of the other subunits shifts the ratchet equilibrium towards the post-translocation state.
Internet interventions for mental health in university students: A systematic review and meta‐analysis

Mental health disorders are highly prevalent among university students. Universities could be an optimal setting to provide evidence‐based care through the Internet. As part of the World Mental Health International College Student initiative, this systematic review and meta‐analysis synthesizes data on the efficacy of Internet‐based interventions for university students' mental health.
Skeletal and soft tissue injuries after manual and mechanical chest compressions.

Aims To determine the rate of injuries related to cardiopulmonary resuscitation (CPR) in cardiac arrest non-survivors, comparing manual CPR with CPR performed using the Lund University Cardiac Assist System (LUCAS). Methods and Results We prospectively evaluated 414 deceased adult patients using focused, standardized post-mortem investigation in years 2005 through 2013. Skeletal and soft tissue injuries were noted, and soft tissue injuries were evaluated with respect to degree of severity. We found sternal fracture in 38%, rib fracture in 77%, and severe soft tissue injury in 1.9% of cases treated with CPR with manual chest compressions (n = 52). Treatment with LUCAS CPR (n = 362) was associated with significantly higher rates of sternal fracture (80% of cases), rib fracture (96%) and severe soft tissue injury (10%), including several cases of potentially life-threatening injuries. Conclusion LUCAS CPR causes significantly more CPR-related injuries than manual CPR, while providing no proven survival benefit on a population basis. We suggest judicious use of the LUCAS device for cardiac arrest.
Development-Dependent Changes in the NR2 Subtype of the N-Methyl-D-Aspartate Receptor in the Suprachiasmatic Nucleus of the Rat

The suprachiasmatic nucleus (SCN) is the main brain clock that regulates circadian rhythms in mammals. The SCN synchronizes to the LD cycle through the retinohypothalamic tract (RHT), which projects to ventral SCN neurons via glutamatergic synapses. Released glutamate activates N-methyl-D-aspartate (NMDA) receptors, which play a critical role in the activation of signaling cascades to enable phase shifts. Previous evidence indicates that presynaptic changes during postnatal development consist of an increase in RHT fibers impinging on SCN neurons between postnatal day (P) 1 to 4 and P15. The aim of this study was to evaluate postsynaptic developmental changes in the NR2 subunits that determine the pharmacological and biophysical properties of the neuronal NMDA receptors in the ventral SCN. To identify the expression of NR2 subtypes, we utilized RT-PCR, immunohistochemical fluorescence, and electrophysiological recordings of synaptic activity. We identified development-dependent changes in NR2A, C, and D subtypes in mRNA and protein expression, whereas NR2B protein was equally present at all analyzed postnatal ages. The NR2A antagonist PEAQX (100 nM) reduced the frequency of NMDA excitatory postsynaptic currents (EPSCs) at P8 significantly more than at P34, but the antagonists for NR2B (3 μM Ro 25-6981) and NR2C/D (150 nM PPDA) did not influence NMDA EPSCs differently at the 2 analyzed postnatal ages. Our results point to P8 as the earliest analyzed postnatal age that shows mRNA and protein expression similar to those found at the juvenile stage P34. Taken together, our findings indicate that postsynaptic development-dependent modifications in the NR2 subtypes of the NMDA receptor could be important for the synchronization of ventral SCN neurons to the LD cycle at adult stages.
Low-dose radiobiology program at Canadian nuclear laboratories: past, present, and future

Abstract Health risks associated with the exposure of humans to low-dose ionizing radiation are currently estimated using the Linear-No-Threshold model. Over the last few decades, however, this model has been widely criticized for inconsistency with a large body of experimental evidence. Substantial efforts have been made to delineate biological mechanisms and health-related outcomes of low-dose radiation. These include a large DOE-funded Low Dose program operated in the 2000s, as well as the EU funded programs, previously NOTE and DOREMI and currently MELODI. Although not as widely known, the Atomic Energy of Canada Limited (AECL) in Chalk River, operated a low-dose radiobiology program since as early as 1948. The Canadian Nuclear Laboratories (CNL), the successor to AECL since 2015, has expanded this program into new areas making it the world’s most robust, centrally coordinated and long-lived research efforts to delineate the biological effects of low-dose radiation. The purpose of this review is to provide a high-level overview of the low-dose radiobiology program maintained at CNL while capturing the historical perspectives. Past studies carried out at CNL have substantially influenced the area of low-dose radiobiology, exemplified by highly cited papers showing delays in spontaneous tumorigenesis in low-dose irradiated mice. The current low-dose research program at CNL is not only addressing a wide range of mechanistic questions about the biological effects of low doses - from genetic to epigenetic to immunological questions - but also moving toward novel areas, such as the dosimetry and health consequences of space radiation and the use of low-dose radiation in cancer therapy and regenerative medicine.
Apps, Avatars, and Robots: The Future of Mental Healthcare

Abstract From artificial intelligence, predictive analytics and biometric sensors, to advanced robotics, virtual reality and mobile applications, rapid advances in technology are transforming the design, delivery and experience of mental healthcare. This paper explores the promise and pitfalls of three technologies (apps, avatars and robots) posed to transform mental health education, practice and research. By highlighting potential practical and ethical implications, this paper argues mental health professionals must actively engage in the co-design and development of new technologies, and reflexively reflect on whether the future will be a techno-utopia or dystopia.
Comparison of three heterochromatin protein 1 homologs in Drosophila

ABSTRACT Heterochromatin protein 1 (HP1) is an epigenetic regulator of chromatin structure and genome function in eukaryotes. Despite shared features, most eukaryotes have a minimum of three HP1 homologs with differential localization patterns and functions. Most studies focus on Drosophila HP1a [also known as Su(var)205], and little is known about the properties of HP1b and HP1c. To determine the features of the three HP1 homologs, we performed the first comprehensive comparative analysis of Drosophila HP1 homologs. HP1 differentially homodimerizes and heterodimerizes in vivo and in vitro. HP1b and HP1c, but not HP1a, are localized to both the nucleus and cytoplasm. The C-terminal extension region (CTE) targets HP1c and HP1b to the cytoplasm. Biochemical approaches show that HP1 binds to various interacting partners with different binding affinities. Each HP1 associates differently with RNA polymerase II; a gene reporter assay revealed that HP1a and HP1b, but not HP1c, inhibit transcriptional activity, suggesting that HP1c serves as a positive regulator in transcription. Thus, these studies provide the basic clues pertaining to the molecular mechanism by which HP1 might control cellular processes in a homolog-specific manner. Summary: A comparative analysis of the three Drosophila HP1 homologs shows that they localize differently, and that HP1a and HP1b repress transcription, whereas HP1c activates transcription.
