Recent scientific evidence suggests that traits energy and fatigue are two unique unipolar moods with distinct mental and physical components. This exploratory study investigated the correlation between mental energy (ME), mental fatigue (MF), physical energy (PE), physical fatigue (PF), and the gut microbiome. The four moods were assessed by survey, and the gut microbiome and metabolome were determined from 16 S rRNA analysis and untargeted metabolomics analysis, respectively. Twenty subjects who were 31 ± 5 y, physically active, and not obese (26.4 ± 4.4 kg/m2) participated. Bacteroidetes (45%), the most prominent phyla, was only negatively correlated with PF. The second …

RATIONALE: Dextro-transposition of the great arteries (D-TGA) is a severe congenital heart defect which affects approximately 1 in 4,000 live births. While there are several reports of D-TGA patients with rare variants in individual genes, the majority of D-TGA cases remain genetically elusive. Familial recurrence patterns and the observation that most cases with D-TGA are sporadic suggest a polygenic inheritance for the disorder, yet this remains unexplored.

OBJECTIVE: We sought to study the role of common single nucleotide polymorphisms (SNPs) in risk for D-TGA.

METHODS AND RESULTS: We conducted a genome-wide association study in an international set of 1,237 patients …

Estrogen receptor–α (ERα) expressed by neurons in the ventrolateral subdivision of the ventromedial hypothalamic nucleus (ERαvlVMH) regulates body weight in females, but the downstream neural circuits mediating this biology remain largely unknown. Here we identified a neural circuit mediating the metabolic effects of ERαvlVMH neurons. We found that selective activation of ERαvlVMH neurons stimulated brown adipose tissue (BAT) thermogenesis, physical activity, and core temperature and that ERαvlVMH neurons provide monosynaptic glutamatergic inputs to 5-hydroxytryptamine (5-HT) neurons in the dorsal raphe nucleus (DRN). Notably, the ERαvlVMH → DRN circuit responds to changes in ambient temperature and nutritional states. We further showed …

Effect Of Seeding Rates On Productivity And Quality Of Alfalfa In Northern Area Of Korea, Jong Geun Kim, C. Liu, S. N. Wei, Y. F. Li, E. C. Jeong, H. J. Kim

IGC Proceedings (1977-2023)

Alfalfa cultivation in South Korea is not common. There are many reasons, but low productivity has been extremely limited. Although alfalfa growth was poor due to boron deficiency in the soil, the problem has recently been solved. Nevertheless, the cultivation of alfalfa is not expanding. About 200,000 tonnes of alfalfa hay are imported every year. Therefore, this study was conducted to find a way to replace imported hay by expanding alfalfa cultivation in Korea. Alfalfa (P5444) was sown in northern part of South Korea (Pyeongchang). Alfalfa was sown in September 2018 with different seeding rates (20, 30 and 40 kg/ha) …

Effect Of Prompt-Delayed Packaging And Ensiling Time On Fermentation And Aerobic Stability Of Soybean Curd Residue, Ajmal Wali, Takeshi Tsuruta, Naoki Nishino

IGC Proceedings (1977-2023)

Wet soybean curd residue (SCR) obtained from two tofu factories (F1 and F2) was anaerobically stored with or without added beet pulp (BP). Sealing was performed on the day of tofu production (prompt sealing [PS]) or 2 days after SCR was piled and unprocessed (delayed sealing [DS]). Predominant lactic acid fermentation was observed regardless of the sealing time and BP addition. Acinetobacter spp. were the most abundant (> 67%) bacteria in pre-ensiled SCR, regardless of the factory and sealing time. In PS silage, the abundances of typical lactic acid-producing bacteria, such as Lactobacillus, Pediococcus, and Streptococcus spp. reached …

Relationship Between Exchangeable Acidity And Persistence Of Orchardgrass (Dactylis Glomerata) In Temperate Pastures Under Different Management, H. Kakihara, S. Ogura

IGC Proceedings (1977-2023)

Orchardgrass is a high productive, highly nutritive grass, but its persistence is low under acid soil condition. Therefore, to obtain the information on the effect of soil acidity on the persistence of orchardgrass in acid soil grasslands, we investigated the relationship between exchangeable acidity (y₁) and orchardgrass in sown pastures. Eight temperate pastures (four cutting meadows [CMs] and four cattle grazing pastures [GPs]) were used for vegetation survey and soil samplings. Six or three line transects (50 m each) were fixed in each meadow or pasture, and measurement location (three quadrats 20 cm×20 cm in size and 50 …

Isotopic Δ15N Signature Of Grass-Alone And Grass-Legume Tropical Pastures To Estimate Sources Of Nitrogen To Grasses In Farmer Managed Pastures, Daniel M. Villegas, J. Velasquez, J. Arango, K. Obregon, Idupulapati M. Rao, G. Rosas, A. Oberson

IGC Proceedings (1977-2023)

Vast areas of tropical forest have been converted into pastures sown with introduced grasses (Urochloa spp.). The majority of pastures exist in some stage of degradation, which has dramatic ecological and economic consequences. Our objective was to determine isotopic ¹⁵N signature of grass alone and grass-legume pastures to estimate sources of nitrogen (N) to grasses in farmer managed pastures. This work contributes to enhancing the sustainability of tropical pastures in forest margins through the integration of legumes. The overarching hypothesis tested was that legumes associated with grasses will improve nutrient supply via symbiotic fixation and mobilization of soil …

Influence Of Grazing Intensity On Nutrient Concentrations In Grass Tissue: Evidence From Two Savannah Grass Species, C. Munyati

IGC Proceedings (1977-2023)

High grazing intensity can accelerate the recycling of animal nutrients on savannah rangelands through the deposition of dung and, subsequently, nutrient mineralisation, uptake and concentration in grass tissue. The actual magnitude of this influence can vary depending on the grazing system. This study derived grazing system-dependent magnitudes of the influence of grazing intensity on concentrations of major (N, P, K, Ca, Mg, Na) and trace (B, Co, Cu, Cr, Fe, Mn, Mo, Ni, Se, Zn) animal nutrients in above ground grass tissue. Two grass species were examined: Brachiaria nigropedata, a decreaser, and Eragrostis lehmanniana, an increaser. For the …

Dietary Lactobacillus Acidophilus Atcc 4356 Relieves The Impacts Of Aflatoxin B1 Toxicity On The Growth Performance, Hepatorenal Functions, And Antioxidative Capacity Of Thinlip Grey Mullet (Liza Ramada) (Risso 1826), Mahmoud A. O. Dawood, Malik M. Khalafalla, Nahed F. A. Zayed, Asem A. Amer

Faculty Journal Articles

Dietary Lactobacillus acidophilus ATCC 4356 was used to relieve the impacts of aflatoxin B1 toxicity on the performances of Liza ramada. The control diet was without any additives, while the second and third diets were supplemented with aflatoxin B1 at 0.5 and 1 mg/kg. The fourth diet was supplemented with Lb. acidophilus ATCC 4356 at 1 × 106 CFU/mL per kg diet, while the fifth with aflatoxin B1 at 1 mg/kg and Lb. acidophilus ATCC 4356 at 1 × 106 CFU/mL per kg diet. The growth performance markedly increased (p < 0.05) in L. ramada fed Lb. acidophilus ATCC 4356, while aflatoxin B1 at 0.5 and 1 mg/kg groups showed a severe reduction. The red blood cells, hemoglobulin, hematocrit, and white blood cells were markedly increased in L. ramada fed Lb. acidophilus ATCC 4356 while decreased (p < 0.05) in fish fed aflatoxin B1 at 0.5 and 1 mg/kg. The blood total protein and albumin were markedly increased (p < 0.05) in L. ramada fed Lb. acidophilus ATCC 4356 while reduced in aflatoxin B1 at 0.5 and 1 mg/kg groups. The levels of total cholesterol and triglycerides were meaningfully increased in fish of the Lb. acidophilus ATCC 4356 and aflatoxin B1 at 1 mg/kg groups while decreased in aflatoxin B1 at 0.5 and 1 mg/kg groups. Alanine aminotransferase, aspartate aminotransferase, creatinine, and urea levels were markedly decreased (p < 0.05) in fish-fed Lb. acidophilus ATCC 4356 while increased in aflatoxin B1 at 0.5 and 1 mg/kg groups. The highest levels of blood glucose and cortisol were seen in fish contaminated with aflatoxin B1 at 1 mg/kg, while the lowest levels were observed in the fish fed Lb. acidophilus ATCC 4356 group (p < 0.05). The catalase and superoxide dismutase were markedly enhanced in the Lb. acidophilus ATCC 4356 group and severely declined in aflatoxin B1 at 0.5 and 1 mg/kg groups (p < 0.05). The malondialdehyde level was markedly reduced in fish fed Lb. acidophilus ATCC 4356 with or without aflatoxin B1 at 1 mg/kg diets while increased in fish contaminated with aflatoxin B1 at 0.5 and 1 mg/kg (p < 0.05). The control group had lower malondialdehyde levels than the aflatoxin B1 at 1 mg/kg group and higher than the Lb. acidophilus ATCC 4356 with or without aflatoxin B1 toxicity (p < 0.05). Histopathological examination revealed impaired intestines and livers in fish contaminated with aflatoxin B1 while Lb. acidophilus ATCC 4356 relieves the inflammation and protected the intestines and livers. In conclusion, dietary Lb. acidophilus ATCC 4356 is recommended to relieve the impacts of aflatoxicosis-induced hepatorenal failure and oxidative stress in L. ramada.

Not So Private, Stacey A. Tovino

Duke Law Journal

Federal and state laws have long attempted to strike a balance between protecting patient privacy and health information confidentiality on the one hand and supporting important uses and disclosures of health information on the other. To this end, many health laws restrict the use and disclosure of identifiable health data but support the use and disclosure of de-identified data. The goal of health data de-identification is to prevent or minimize informational injuries to identifiable data subjects while allowing the production of aggregate statistics that can be used for biomedical and behavioral research, public health initiatives, informed health care decision making, …

INTRODUCTION: Behavioural interventions in early life appear to show some effect in reducing childhood overweight and obesity. However, uncertainty remains regarding their overall effectiveness, and whether effectiveness differs among key subgroups. These evidence gaps have prompted an increase in very early childhood obesity prevention trials worldwide. Combining the individual participant data (IPD) from these trials will enhance statistical power to determine overall effectiveness and enable examination of individual and trial-level subgroups. We present a protocol for a systematic review with IPD meta-analysis to evaluate the effectiveness of obesity prevention interventions commencing antenatally or in the first year after birth, and …

Frank, Christopher J. Mclouth, Amanda L. Trout, Andrew J. Morris, Jianzhong Chen, Ann M. Stowe, Justin F. Fraser, Keith R. Pennypacker

Behavioral Science Faculty Publications

Introduction: Short chain fatty acids (SCFA) are gut microbiota-derived metabolites that contribute to the gut-brain axis and may impact stroke outcomes following gut dysbiosis. We evaluated plasma SCFA concentrations against stroke severity parameters and identified SCFA-associated protein networks.

Methods: The Blood and Clot Thrombectomy Registry and Collaboration (BACTRAC), a continuously enrolling tissue bank, was used to obtain stroke samples. Arterial blood distal and proximal to the thrombus was obtained from Acute Ischemic Stroke (AIS) Patients (n=53) during thrombectomy. Patient demographics, stroke presentation and outcome parameters were reported. The SCFAs were isolated from proximal plasma via chemical derivatization UHPLC coupled tandem …

Prenatal Exposure To Maternal Psychological Distress And Telomere Length In Childhood, Stephanie A. Stout-Oswald, Laura M. Glynn, Marco Bisoffi, Catherine H. Demers, Elysia Poggi Davis

Psychology Faculty Articles and Research

Telomere length (TL) is a biological marker of cellular aging, and shorter TL in adulthood is associated with increased morbidity and mortality risk. It is likely that these differences in TL are established long before adulthood, and there is growing evidence that TL can reflect prenatal experiences. Although maternal prenatal distress predicts newborn TL, it is unknown whether the relation between prenatal exposure to maternal distress and child TL persists through childhood. The purpose of the current longitudinal, prospective study is to examine the relation between prenatal exposure to maternal distress (perceived stress, depressive symptoms, pregnancy-related anxiety) and TL in …

Sustainability Of Mahogany Production In Plantations: Does Resource Availability Influence Susceptibility Of Young Mahogany Plantation Stands To Hypsipyla Robusta Infestation?, C. B. Darko, E. Opuni-Frimpong, S. A. Owusu, B. Kyere, A. J. Storer

Michigan Tech Publications, Part 1

Hypsipyla robusta Moore (Lepidoptera: Pyralidae), like many other moth species, shows selectivity when choosing host plants for its eggs. Four Meliaceae species (Khaya grandifoliola, K. ivorensis, Swietenia macrophyla, and Entandrophragma cylindricum) were established in a moist semideciduous forest in Ghana to study this selectivity at 12 and 21 months after planting. The analysis of variance (ANOVA) at a P-value of 0.05 was used to test the significance of differences in infestation by H. robusta between the species. H. robusta attacks were recorded by month 12 after planting in the field, and only Khaya spp. was attacked, with attacks evident on …

The Impact Of Aging On The Lung Alveolar Environment, Predetermining Susceptibility To Respiratory Infections, Jordi B. Torrelles, Blanca I. Restrepo, Yidong Bai, Corinna Ross, Larry S. Schlesinger, Joanne Turner

School of Medicine Publications

Respiratory infections are one of the top causes of death in the elderly population, displaying susceptibility factors with increasing age that are potentially amenable to interventions. We posit that with increasing age there are predictable tissue-specific changes that prevent the immune system from working effectively in the lung. This mini-review highlights recent evidence for altered local tissue environment factors as we age focusing on increased tissue oxidative stress with associated immune cell changes, likely driven by the byproducts of age-associated inflammatory disease. Potential intervention points are presented.

Ecology Of Periphyton In A Subtropical River Floodplain, Kamela De Gallardo

LSU Doctoral Dissertations

The Atchafalaya River Basin (ARB) in southcentral Louisiana, USA, is a large and biologically diverse floodplain surrounding the Atchafalaya River (AR), which is the largest distributary of the Mississippi River, receiving 30% of the combined daily discharge of the Mississippi and Red Rivers. Annual flooding facilitates exchange between the AR and its floodplain and is thought to give rise to the high productivity of the river-floodplain system. Primary production within the aquatic ARB is driven by periphytic algae, phytoplankton, and aquatic macrophytes, however, very little is known about periphytic algal assemblages in floodplain systems. In this study, artificial substrates were …

Seasonality And Grazing Management Effect On Growth And Nutritional Composition Of Herbage On Semi-Natural Grasslands Grazed By Dairy Cows In Southwest Germany, E. Velasco, S. Perdana-Decker, J. Werner, U. Dickhoefer

IGC Proceedings (1977-2023)

Natural and semi-natural grasslands represent an attractive forage source for cows in organic dairy farming. Throughout the grazing season, however, diverse factors such as climatic conditions, botanical composition, as well as grazing and herd management, can influence growth and nutritive value of forage on grasslands. We aimed at investigating the influence of seasonality and grazing management in forage growth and nutritional quality in seven commercial organic dairy cattle farms during the grazing season 2019 in South Germany. Therefore, forty exclusion cages (1 m²) were installed on pastures, which were under three different grazing systems: rotational, short-grass, and continuous …

Effect Of Cutting Stage And Turning Frequency On Nutritive Value And Digestibility Of Two Tropical Forages, M. M. Chiphwanya, F. C. Chigwa, H. D. C. Msiska

IGC Proceedings (1977-2023)

In Malawi, feed shortage during the dry season (June-October) is a critical factor affecting smallholder dairying. Though suitable improved forages were long introduced, important parameters that indicate forage and hay quality for dry season feeding have been less well studied. This study evaluated the effect of cutting stage and turning frequency at drying of two tropical forages on nutrient composition and digestibility. A 2³ factorial experiment laid out in Randomized Complete Block Design was conducted in Mzuzu milk shed area. Centrosema pubescens and Chloris gayana were established on four plots (5m x 3m) each by 24 dairy farmers; two …
