EXTRACTION AND CHARACTERIZATION OF RICE BRAN OIL (RBO) FOR POTENTIAL APPLICATION AS BIODIESEL
No full textAbstract: Rice bran oil (RBO) is a potential feedstock for biodiesel and biolubricant production among other alternative sources. The rice bran’s fat extraction was carried out using maceration with chloroform, solvent recovery as a means of purification was carried out using rotary evaporator. Physicochemical analysis such as percent extraction and Gas Chromatography-Mass Spectrometry (GC-MS), iodine value, peroxide value and saponification values were carried out to ascertain its potential application as Biodiesel. From the GC-MS analysis, over 30 compounds including fatty acids and other phytochemicals were discovered with Oleic acid having the greater percentage of 34.5% having the base peak at m/z of 282.
Keywords: Rice bran oil (RBO), biodiesel, biolubricant production.

No full textSOLID STATE FERMENTATION OF RICE BRAN: NUTRITIONAL VALUES AND FUNCTIONAL PROPERTIES
No full textAbstract: Solid state fermentation of rice bran improves nutritional values and functional properties. The edible fungus, Pleurotus Sapidus, was employed for the solid state fermentation. During fermentation, the sample was withdrawn after ten days and further analyzed. An investigation process was carried out on the solid-state fermented rice bran (RB) in comparison with the unfermented (normal) rice bran. The few analyses that were investigated in comparison with the unfermented rice bran were the density tests (bulk, tapped and compact), water and oil absorption capacities, swelling power, moisture estimate, pH, reducible sugar, and water solubility. From the results, it was found that both the fermented and unfermented rice bran have a pH of 5 and 6, respectively, with absorption capacities of both oil (5% for the fermented sample and 20% for the unfermented sample) and water (10% for the fermented sample and 25% for the unfermented sample), and both samples possess swelling power. This study demonstrated a comparison in the nutritional quality of RB after fermentation with Pleurotus sapidus in an attempt to find or improve the functional and nutritional value of rice bran via solid state fermentation. The study therefore proves that the functional and nutritional value of the unfermented sample, which has a higher phenol concentration from spectrophotometry and high ascorbic acid, was better than the fermented sample with lower phenol concentration and less ascorbic acid.
Keywords: Solid state fermentation, rice bran, high ascorbic acid.

Ab initio modeling and experimental investigation of Fe2 P by DFT and spin spectroscopies
No full textFe2P alloys have been identified as promising candidates for magnetic refrigeration at room-temperature and for custom magnetostatic applications. The intent of this study is to accurately characterize the magnetic ground state of the parent compound, Fe2P, with two spectroscopic techniques, μSR and NMR, in order to provide solid bases for further experimental analysis of Fe2P-type transition metal based alloys. We perform zero applied field measurements using both techniques below the ferromagnetic transition TC=220 K. The experimental results are reproduced and interpreted using first principles simulations, validating this approach for quantitative estimates in alloys of interest for technological applications.</p
Anti-malarial and Anti-bacterial properties of some selected species of Asteraceae family
No full textAbstract: Bioactive natural plants, including the Asteraceae family have several therapeutic effects and antimicrobial properties. They are used in different cultures across the world as alternative medicine for treatments of several ailments including prevalent malaria infection, wound healing, diabetes, anti-ulcerative, anti-bacterial, treatment of liver disease, accelerates blood clotting, relieves muscle cramps during menstruation and treatment of common colds. In this review, some selected species of the Asteraceae families such as Vernonia amygdolina, artemisia annua and ageratum conyzoides amongst others were evaluated for their anti-malarial and antimicrobial properties. Major and minor bioactive chemical ingredients in each species were discussed, especially their chemical structures and inherent functional groups.
This approach is intended to guide future research on drug development and drug discovery. This is especially important as we are set to finding lasting solution to multidrug resistance microbial infection and other life-threatening ailments, such as malaria, and cancer that confront our daily lives. Asteraceae family in general can be used as safe preservatives and food additives to improve the health role of food. This is attributed to their good flavor, antioxidant, and antimicrobial effect.
Keywords: Bioactive plants; Asteraceae; therapeutic effects; antimicrobial effect; anti-malarial.

When identity hurts: how positive intragroup experiences yield negative mental health implications for ethnic and sexual minorities
No full textThis is the author accepted manuscript. The final version is available from the publisher via the DOI in this record.Two studies (longitudinal, N=510; cross-sectional; N=249) explain how feeling
valued in one’s ethnic/sexual minority group has benefits for mental health but also certain
costs through the way it shapes minorities’ identity. Drawing from the intragroup status and
health model (ISAH) we posit that when individuals feel valued in their minority group it
bolsters group identification; with greater identity-centrality individuals tend to view daily
social interactions through the ‘lens’ of their minority group and ultimately perceive more
discrimination. Discrimination, in turn, negatively shapes health. Thus, feeling valued in
one’s minority group has benefits for health but also indirect costs, perhaps counterintuitively
by strengthening minority group identity. Both studies supported these predictions. Study 2
also supported an adapted ISAH model, for use in the context of concealable stigmatized
identities (sexual minorities). Overall, the ISAH model explains why feeling valued and
having strong social identities are not always beneficial, yielding certain costs for stigmatized
individuals’ health
Mechanical thrombectomy beyond the circle of Willis: efficacy and safety of different techniques for M2 occlusions
No full textFull author list omitted for brevity. For the full list of authors, see article.BACKGROUND: M2 segment occlusions represent approximately one-third of non-lacunar ischemic stroke and can lead to permanent neurological deficits. Various techniques are available for mechanical thrombectomy beyond the circle of Willis, but data evaluating their effectiveness and safety are lacking. METHODS: A retrospective review of patients with ischemic stroke undergoing mechanical thrombectomy for M2 occlusions from 13 centers in North American and Europe was performed. Tandem or multiple-territory occlusions were excluded. The primary outcome was 90-day modified Rankin Scale and reperfusion rates across stent-retriever, direct aspiration and combined techniques. RESULTS: There were 465 patients (mean age 71.48+/-14.03 years, 53.1% female) with M2 occlusions who underwent mechanical thrombectomy. Stent-retriever alone was used in 133 (28.6%), direct aspiration alone in 93 (20.0%) and the combined technique in 239 (51.4%) patients. Successful reperfusion was achieved with the combined technique in 198 (82.2%; OR 2.6 (1.1-6.9)), with stent-retriever alone in 112 (84.2%; OR 9.2 (1.9-44.6)) and with direct aspiration alone in 62 (66.7%; referencecategory). Intraprocedural subarachnoid hemorrhages (iSAH) were 36 (7.7%) and were more likely to occur in patients treated with the stent-retrievers (OR 5.0 (1.1-24.3)) and combined technique (OR 4.6 (1.1-20.9)). Good clinical outcome was achieved in 260 (61.8%) patients, while 59 (14.0%) patients died. Older age, higher baseline NIHSS (National Institutes of Health Stroke Scale), parenchymal hemorrhage and iSAH were associated with poor outcome while successful recanalization and higher baseline ASPECTS (Alberta Stroke Program Early CT Score) were associated with good outcome. No differences were found among the three techniques in terms of clinical outcome. CONCLUSION: Stent-retrievers and a combined approach for M2 occlusions seem more effective than direct aspiration, but with higher rates of iSAH. This leads to no detectable difference in clinical outcome at 3 months
Is it always good to feel valued? The psychological benefits and costs of higher perceived status in ones ethnic minority group
No full textThis is the author accepted manuscript. The final version is available from SAGE Publications via the DOI in this record.Two studies (N = 1,048) examined how Blacks’, Asians’, and Latinos’ perceived value within their own ethnic group (ethnic intragroup status) shapes mental health (depression, anxiety, psychological distress). The proposed intragroup status and health (ISAH) model predicts that feeling valued among ethnic ingroup members has benefits for health, but also indirect costs. Costs arise because individuals who feel highly valued in their ethnic group see their ethnicity as more central to their self-concept; with stronger identity-centrality, individuals more frequently view daily social interactions through the “lens” of their ethnicity and ultimately perceive/experience more discrimination. Discrimination, in turn, adversely shapes mental health. Results of structural equation modeling supported these predictions across all groups in both studies. Thus, feeling valued in one’s minority group may be a double-edged sword for mental health. Overall, the ISAH model reveals how intragroup processes, when considered from an intergroup perspective, advance our understanding of minority mental health
