La vitamine E : état actuel des connaissances, rôle dans la prévention cardio-vasculaire, biodisponibilité

Les proprietes anti-oxydantes de la vitamine E – qui font l’objet d’une large majorite des travaux effectues actuellement sur cette vitamine – n’ont ete reconnues qu’au cours des annees 50. La vitamine E avait cependant ete decouverte quelque trente ans plus tot. Mais, paradoxe interessant, son role comme micronutriment essentiel n’a ete reconnu qu’a la fin des annees 60. Cette vitamine jouit d’un certain nombre de particularites. C’est l’anti-oxydant majeur des milieux lipidiques (huiles, membranes biologiques, lipoproteines). Elle presente differentes formes moleculaires : des vitameres a, b, g et d, chaque vitamere existant sous differentes formes stereo-isomeriques dont une seule, parmi les huit formes possibles, est naturelle : la forme RRR (figure 1). La molecule presente deux parties : un noyau 6-OH-chromane qui possede la fonction anti-oxydante, et une chaine laterale a 16 atomes de carbone de structure isoprenique, celle-ci definissant deux grandes familles : les tocopherols a chaine laterale saturee et les tocotrienols avec une chaine laterale presentant trois doubles liaisons. Cette chaine laterale determine la lipophilicite et la stereochimie de la molecule. C’est la stereochimie de la molecule qui determine a son tour la reconnaissance preferentielle de la forme RRR-a-tocopherol par un transporteur hepatique specifique dont le role physiologique est aujourd’hui reconnu. Chacune de ces formes moleculaires (le nombre theorique est de 64) peut etre caracterisee par une activite vitaminique E, definie par reference au pouvoir anti-abortif chez la rate gestante. Les tableaux 1 et 2 donnent cette activite en fonction de la molecule consideree. La forme naturelle de l’a-tocopherol, le RRR-a-tocopherol, possede l’activite la plus elevee, alors que la stereo-isomerie de la molecule n’exerce aucun effet sur ses proprietes anti-oxydantes. Enfin, c’est a partir de la fin des annees 70 et du debut des annees 80 que les proprietes cellulaires regulatrices de la vitamine E vont etre revelees. Elles font aujourd’hui l’objet de recherches actives sur les cascades de signalisation affectant differentes fonctions cellulaires. Elles ne semblent pas correlees aux proprietes anti-oxydantes mais pourraient impliquer des etapes de reconnaissance stereo-dependantes.
Individualizing Oral Feeding Assessment and Therapies in the Newborn

: Oral feeding competency is a milestone most infants must achieve prior to discharge. It is a developmentally complex task that requires integration of multiple sensory inputs, central nervous system maturation, motor coordination, and respiratory stability. While ensuring safety during oral feeding is important to reduce morbidities, we must optimize developmental windows to expedite feeding maturation. Currently, many of the assessments and therapies related to oral feeding skills focus solely on nutritive and non-nutritive sucking. Yet, this essential re ﬂ ex is only one component of oral feeding. Speci ﬁ c challenges faced by individual newborns are often unique, and delays in development in any one of the many systems involved in oral feeding can lead to prolonged oral feeding maturation. Expanding the ﬁ eld to go beyond targeting oral motor skills to consider all aspects of feeding maturity, inclusive of sensory integration and hunger signaling, is needed to advance care. As technology continues to develop at a rapid pace, the ﬁ eld must compare the ef ﬁ cacy of these clinical and technologic assessments and therapies. In this review, we will address the complexity of neonatal feeding, review assessment tools and interventions for feeding safety and developmental readiness, and propose an individualized, multi-faceted approach to oral feeding evaluation and intervention.
Beauty influencer in the digital age: How does it influence purchase intention of generation Z?

This research examined the influence of social media advertising conducted by beauty influencers. The researchers analyzed the impact of Celebrity Credibility (i.e., Expertise, Trustworthiness, and Attractiveness), Reputation, and Persuasive Capabilities toward Purchase Intention. The respondents in this research were 154 young women from Generation Z who lived in the Greater Jakarta (Jabodetabek) area and followed the social media beauty influencers who endorsed a renowned homegrown cosmetics brand. This research utilized a quantitative method using the Multiple Linear Regression analysis. The results of this study showed that only two independent variables associated with the beauty influencer, namely, Attractiveness and Persuasive Capabilities, yielded a significantly positive influence toward Purchase Intention. In contrast, the rest of the variables were not significant. All independent variables had a simultaneously significant impact on Purchase Intention. Finally, all independent variables contributed 72.4% to the dependent variable, while the rest were explained by other variables not examined in this research.
Flow cytometry for the evaluation of chromosomal damage in turbot Psetta maxima (L.) exposed to the dissolved fraction of heavy fuel oil in sea water: a comparison with classical biomarkers

Turbot Psetta maxima were exposed 5 days to the dissolved fraction of fuel oil number 2, then decontaminated over 30 days in clean sea water. Biliary metabolites and ethoxyresorufin-O-deethylase (EROD) activity were evaluated during and after the contamination. These results were compared with chromosomal damage measured by flow cytometry (FCM). Erythrocyte nuclear abnormality, micronuclei and immaturity were also evaluated over the exposure period. Biliary metabolites and EROD analyses showed a clear and early response: biliary metabolites were detected from the first day of contamination to the 14th day of depuration, EROD activity increased during the contamination period reached a maximum 3 days after the beginning of the decontamination and decreased to the control value after 1 month of depuration. FCM showed a bimodal response: a first increase of coefficient of variation of blood cell DNA content was observed during the contamination and a second one started after 14 days of depuration and was maintained for at least 2 weeks. Erythrocyte morphology analysis showed a strong increase in nuclear abnormality during the contamination period. These results confirm previous work and show that in the context of marine accidental pollution by heavy fuel oil, the measurements of chromosomal damage by FCM allow the detection of a genotoxic response in fishes.
The nexus between moral licensing and behavioral consistency: Is organic consumption a door-opener for commitment to climate protection?

ABSTRACT Organic consumption and the commitment to climate protection via carbon offsetting are important for the protection of global natural resources. This paper analyzes the relationship between these behaviors and examines factors that explain behavioral (in) consistency across these behavioral fields. Thereby, we examine the influence of priming by an “organic offer” on subsequent monetary donations via carbon offsetting. Here, for the first time, we investigate the interaction between priming, ethical mindsets (rule-based or outcome-based mindsets), environmental values and moral identity. The study is based on a laboratory experiment with students which was conducted in December 2017 (n = 226). The main results show that the three-way interaction between priming by an “organic offer,” rule-based mindsets and environmental values is associated with a higher likelihood for actual carbon offsetting. Furthermore, the findings indicate that moral identity neither interact with rule-based nor with outcome-based mindsets. However, an interaction between priming by an “organic offer” and outcome-based mindsets leads to a lower likelihood for carbon offsetting, which speaks for moral licensing effects.
Some Effects of Cage and Floor Rearing on Commercial White Leghorn Pullets During Growth and the First Year of Egg Production

Abstract Cage and floor-pen rearing effects on body weights and livability of pullets of three White Leghorn commercial strains were compared during the rearing period. When variances of body weights were compared within strains at eight ages, greater variability was detected in 4 of 24 comparisons for caged pullets and in 3 of 24 comparisons for floor-pen pullets. Pullets reared in cages were heavier at 5, 11, and 19 wk of age. Livability scores did not differ for pullets in the two rearing environments. Differences in body weight, present among the three genetic stocks at most ages during the rearing period, diminished with age and were no longer present at 19 wk. No genetic stock × rearing environment interactions were evident for body weights during the rearing period. Carry-over effects from cage and floor pen rearing into the laying period were small and transient; pullets reared in cages attained sexual maturity . 2 wk earlier and had 6% higher hen-housed egg production for the first 4-wk period. However, when compared for the full 48-wk laying period, no significant differences associated with rearing environments were found for livability, rate of lay, hen-housed egg production, egg weight, or egg mass. Although 32 g heavier when housed at 19 wk, cage-reared hens did not differ significantly in body weight from floor-pen reared hens at 20, 50, and 67 wk. Hens reared in cages had better feather scores at 60 to 63 wk of age, but no difference was evident at 75 to 78 wk. Although differences among the genetic stocks were present for productivity traits, nervousness, and feather coverage, genetic stock × rearing environment interactions were generally absent during the laying period.
Slacklining Improves Functional Independence, Fatigue and Balance 2 Years Post Severe Traumatic Brain Injury: A Single Case Study

Objective: Individuals with traumatic brain injury (TBI) recover functional independence to varying degrees due to numerous factors. However, plateaued recovery often initiates between 6-12 months. We investigated whether introducing slacklining, a whole-body interactive balance approach, would provide further improvement in a chronic severe-TBI patient. Methods: A retrospective pragmatic single case-report on a 40-year-old woman two-years post severe-TBI working part-time. Global-functional status had plateaued with ongoing affected balance, left-sided weakness, and fatigue. Slacklining was added to an existing daily multi-disciplinary, self-managed rehabilitation program initially ‘ad-hoc’ and self-managed over nine weeks (Phase-1); then formalized therapist-directed over four weeks (Phase-2). The primary outcome was global-functional status; secondary was the 4-stage 20-step slackline graded-progression, and fatigue; tertiary was balance. All outcomes were reported at slacklining initiation (baseline) and Phase-1 and Phase-2 completion. Findings/ Results: Improvements were found from baseline till Phase-1 completion, and subsequently Phase-2 completion. Global-functional status increased 15% in Phase-1 (baseline=22% to completion=37%); and 18% in Phase-2 (completion=55%); slackline ability from baseline=step-1 to Phase-1 completion=step-6 then Phase-2 completion=step-10; balance duration increased 1.5-fold in Phase-1 and 3-6-fold in Phase-2; and fatigue reduced 22% overall baseline=63% to Phase-2=41% (no Phase-1 measure). Balance, confidence, and function were all self-reported as improved from baseline to program completion. Conclusions: The findings provide evidence for using slacklining to overcome plateaued recovery during rehabilitation of a severe-TBI patient; and imply that supervised programs have greater impact than un-supervised. Further research is required to determine slacklining’s efficacy for TBI, and potentially concussion, through dose, frequency, and intensity.
Women running the party and women running for Congress: An examination of state party diversity and candidate emergence in the 2018 midterm elections

Using a new data set of state political party bylaws and demographics of state party chairs, I evaluate whether women were more likely to run for Congress during the 2018 midterm elections from parties with higher levels of gender diversity. I construct three measures of gender diversity, whether each party was chaired by a woman, granted committee membership to an allied women’s group, and required gender parity among their committee members. Democratic parties are more likely to be chaired by a woman and to require gender parity among their members, but Republican parties are more likely to grant membership to allied women’s groups. Considering the implications of these rules, I find Democratic women were more likely to run for Congress representing parties that grant membership to an allied women’s group and parties chaired by a woman.
The synthesis of highly active carbon dot-coated gold nanoparticles via the room-temperature in situ carbonization of organic ligands for 4-nitrophenol reduction

Due to the serious pollution issue caused by 4-nitrophenol (4-NP), it is of great importance to design effective catalysts for its reduction. Here, a novel and simple strategy was developed for the synthesis of carbon dot-decorated gold nanoparticles (AuNPs/CDs) via the in situ carbonization of organic ligands on AuNPs at room temperature. The enhanced adsorption of 4-NP on CDs via π–π stacking interactions provided a high concentration of 4-NP near AuNPs, leading to a more effective reduction of 4-NP.
Effect of Environmental Temperature, Dietary Protein, and Energy Levels on Broiler Performance

Abstract The rationale for conducting the research was to determine the optimum dietary protein and energy concentration for maximum performance of broilers housed in different environmental temperatures. Male broilers were house in temperatures ranging from 21.1°C to 35°C and fed grower diets containing either 3050 or 3250 kcal ME/kg with five different levels of CP and amino acids. The broilers fed the high energy diets across all temperatures had significantly improved feed conversions and protein utilization. A significant interaction between dietary CP and ME occurred because broilers fed the low energy diets across all temperatures did not show gains related to increasing protein levels, thus indicating that energy intake was the limiting nutrient. The maximum average weight gain occurred for broilers house at 21.1°C and the best average feed conversion was produced at 26.6°C. The reduction in weight gain, feed intake, feed conversion, protein utilization, and energy utilization, along with an increased percent body fat for broilers housed at temperatures >26.6°C and fed diets 21.6% CP indicated that protein and amino acid levels greater than NRC suggested levels do not compensate for lower feed intake.
Egg quality and blood parameters of “Bianca di Saluzzo” and Isa Brown hens kept under free range conditions

Abstract Egg quality traits and some blood parameters of Bianca di Saluzzo hen (BSh) were compared to Isa Brown hen (IBh). Birds were reared in free range conditions. Weight of the whole egg was higher (P≤0.01) for IBh, due to its higher amount of albumen (P≤0.01) whereas BSh egg showed the highest weight and relative percentage of yolk (P≤0.01). IBh and BSh egg chemical composition was similar. Total red cells did not show statistical differences between groups, while total leucocytes were lower (P≤0.05) for BSh Heterophyl/Lymphocyte (H/L) ratio of BSh was lower (P hens. than IBh (0.33 vs. 0.82). IBh α-1 acid glycoprotein (AGP) mean concentrations were affected by time: the values registered after 15 d (T1) and 2 months (T2) of observation were similar (345±132 and 279±58 μg/ml r while AGP value registered after 4 months (T3) were significantly higher espectively), (700±487 μg/ml); BSh did not display any AGP statistical variation over time. IBh albumin mean concentration (1.62 g/dL) was statistically lower than BSh values (1.89 g/dL); in both groups no effect of time of sampling was recorded. Acute phase protein (APP) values of BSh suggested a more adaptive attitude to free range conditions and appeared more constant over time. The present findings suggest genetic or adaptive differences affecting egg quality, physiological and immunological parameters. ≤0.01)
A New Species of Minute Hyla from the Southwestern Amazon Basin (Amphibia, Anura, Hylidae)

Hyla joannae spec. nov., a new small species of hylid frog, is described from Cobija, Departamento Pando, northern Bolivia. The new species is most similar to Hyla leali from which it differs mainly by smaller size, shorter snout, more protuberant eyes, more tuberculate dorsal skin, and a red inner iris in life. Morphological characters and advertisement call of Hyla joannae spec. nov. suggest it being related to the Hyla microcephala group. Differences in recordings of Hyla leali calls are discussed and compared to calls of the new species.
Soil Amendments Affecting Nickel and Cobalt Uptake by Berkheya coddii : Potential Use for Phytomining and Phytoremediation

Plants with inordinately high concentrations of heavy metals (‘hyperaccumulators’) can be used for phytoremediation (removal of contaminants from soils) or phytomining (growing a crop of plants to harvest the metals). Pot trials were used to investigate the effects of MgCO3, CaCO3, sulphur, chelating agents (NTA, DTPA, EDTA) and acid mine tailings on nickel and cobalt uptake by the South African nickel hyperaccumulator Berkheya coddii. Plants were grown in a nickel-rich ultramafic (‘serpentine’) soil diluted with pumice. Both MgCO3and CaCO3caused significant decreases in the uptake of both metals, as well as decreasing their solubility in the soil. After the addition of MgCO3,there was a significant increase in soil pH, so the reduction in plant-metal uptake could not be solely attributed to the action of magnesium alone. Since CaCO3had no significant effect on soil pH, this indicated that calcium inhibits the uptake of both cobalt and nickel. All three chelating agents caused a significant reduction in plant uptake of nickel, despite increasing the solubility (plant availability) of these elements in the soil. Cobalt uptake was unaffected. Sulphur, and the addition of acid mine tailings, caused a highly significant increase in nickel and cobalt uptake, relative to the controls. Sulphur could be used as a low-cost soil amendment to enhance the metal uptake of crops grown on ultramafic soils. Thus, land management procedures would enhance phytoremediation and phytomining operations for nickel and cobalt.
Growth of Bacillus subtilis and Spore Germination in Soil Observed by a Fluorescent-antibody Technique

Vegetative bacteria of Bacillus subtilis placed in contact with an acid forest soil initially declined in number but grew after the development of fungal hyphae. Growth did not occur in sterile soil, nor in alkaline forest soil unless fungal growth was stimulated. Spores of B. subtilis would not germinate in the same acid forest soil unless fungal growth took place, and hardly germinated at all in the alkaline soil. Roots of seedlings of Pinus sylvestris inhibited both vegetative growth and spore germination. These results are consistent with the observed distribution of vegetative bacteria and spores of B. subtilis in forest soils.
Differences in chemical composition between nonflocculated and flocculated Azospirillum brasilense Cd

A two-step broth replacement method was used to induce Azospirillum brasilense Cd bacteria to flocculate in vitro. Nonflocculated and flocculated cells were compared with regard to total cellular lipid composition, fatty acid profiles, and poly-beta-hydroxybutyrate (PHB), protein, and carbohydrate contents. The fatty acid profiles of nonflocculated and flocculated cells were qualitatively identical. Two unsaturated fatty acids, octadecanoate (18:1 cis-9) and hexadecanoate (16:1 cis-9), accounted for approximately 80% of the total fatty acid content in both phenotypes. The major lipids in nonflocculated and flocculated A. brasilense Cd cells were phosphatidylethanolamine, phosphatidylglycerol, and phosphatidylcholine. The process of flocculation also resulted in the synthesis de novo of a glycolipid and cardiolipin. Flocculation also resulted in a decrease in total cellular protein and lipid content and a proportional increase in total cellular PHB and carbohydrate content. Results indicated that the two-s.
Isolation and Purification of an Anticoagulant from Schizymenia dubyi by Fermentation

Natural fermentation is a method of extracting anticoagulant compounds from red algae Schizymenia dubyi. Preliminary screening was carried out on the basis of the activated partial thromboplastin time (APTT), prothrombin time (PT), and thrombin time (TT) assays. The optimal fermentation time period for the highest APTT, PT, and TT values was found to be 8 weeks. Purification of the fermented sample by DEAE-anion exchange chromatography followed by Sepharose-4B chromatography resulted in a single polysaccharide, which was reconfirmed by a single spot on agarose gel electrophoresis. The purified sample had >1000s APTT activity at 130 μg/mL. The molecular weight estimated by polyaccrylamide gel electrophoresis was >500,000 Da. This is the first report indicating the presence of the anticoagulant compound in S. dubyi.
The chemistry of several novel bioconversion lignins

Fourteen lignin-rich residues from six different bioconversion technology schemes currently under investigation for converting lignocellulosic resources into chemicals were analyzed with regard to their chemical structures. Process schemes included (a) acid hydrolysis with sulfuric acid, (b) acid hydrolysis with hydrofluoric acid, (c) steam explosion followed by solvent or alkali extraction, (d) organosolv pulping, and (e) digestion with cellulase or (f) digestion with cellulase-producing organisms. The quantitative analysis regime tested for elemental composition, functionally, interunit linkages, molecular mass, and glass transition temperature. The results were computed on the basis of the composition of average lignin-building, phenylpropane (C/sub 9/) structures. They suggest (a) that bioconversion lignins are subject to, in part, severe hydrolytic depolymerization of their alkyl aryl ether bonds, (b) that the degree of depolymerization differs significantly with the process, (c) that significant secondary condensation occurs only during acid hydrolysis, and, to a minor extent, during steam explosion and organosolv pulping, (d) that, except for phenolic hydroxyl groups, only minor variations in functionality exist, (e) that molecular mass ranges between 500 and 20,000 (g/M) and was lowest with the organosolv and steam explosion lignins, (f) that glass transition temperatures vary between 95 and 160 degrees C, and (g) that the isolationmore » of homogeneous, solvent-or alkali-soluble, lignin-rich fractions from the residues of the HF acid hydrolysis and the cellulolytic enzyme process options is extremely difficult. 68 references. « less
