Nutrient Composition of Mushroom: Pleurotus Ostreatus (Jacaum, ex. Fr. Kummer) grown on Different Agricultural Wastes

The study evaluated the nutrient compositions of Pleurotus ostreatus (Jacaum, ex. Fr. Kummer) grown using different agricultural waste: sawdust, sugarcane (Sacharum officinarum) peels, plantain leaves and corn cobs. The proximate compositions of P. ostreatus fruit bodies varied significantly (P≤ 0.05). Matured fruit bodies of P. ostreatus harvested from sawdust and sugarcane peel substrates had significantly (P≤ 0.05) the highest content of moisture (15.20%) and ash (5.23%) respectively. The Corn cob substrates yielded P. ostreatus with significantly (P≤ 0.05) the highest amount of protein (9.38%) and lipids (8.5%); and lowest amount of carbohydrates (51.76%). Crude fibre was found more in the fruit bodies of P. ostreatus harvested from sugarcane peel substrates (8.23%) followed by corn cobs (7.28% ). The mineral content varied significantly (P≤ 0.05) from 0.43 - 0.90, 0.12 - 0.30, 9.20 - 14.6, 7.30 -13.0 and 1.5 - 2.7 mg/100g for iron, sodium, potassium, phosphorus and calcium respectively. P. ostreatus from sugarcane peels had significantly (P≤ 0.05) the highest mineral content except for calcium. Vitamin C content ranged from 1.3 mg/100g for corn hob to 1.8mg/100g for sawdust. The study revealed that sugarcane peel and corn hob in terms of the proximate and mineral composition are better substrate for the growth of P. ostreatus. It is therefore recommended that these agricultural wastes should be used in the cultivation of P. ostreatus. Besides producing nutritious mushrooms, this will help to reduce the huge agricultural wastes within our environment that sometimes when not properly managed caused serious environmental pollution

Association of acculturation with cardiac structure and function among Hispanics/Latinos: a cross-sectional analysis of the echocardiographic study of Latinos.

OBJECTIVE:Hispanics/Latinos, the largest immigrant population in the USA, undergo the process of acculturation and have a large burden of heart failure risk. Few studies have examined the association of acculturation on cardiac structure and function. DESIGN:Cross-sectional. SETTING:The Echocardiographic Study of Latinos. PARTICIPANTS:1818 Hispanic adult participants with baseline echocardiographic assessment and acculturation measured by the Short Acculturation Scale, nativity, age at immigration, length of US residence, generational status and language. PRIMARY AND SECONDARY OUTCOME MEASURES:Echocardiographic assessment of left atrial volume index (LAVI), left ventricular mass index (LVMI), early diastolic transmitral inflow and mitral annular velocities. RESULTS:The study population was predominantly Spanish-speaking and foreign-born with mean residence in the US of 22.7 years, mean age of 56.4 years; 50% had hypertension, 28% had diabetes and 44% had a body mass index &gt;30 kg/m2. Multivariable analyses demonstrated higher LAVI with increasing years of US residence. Foreign-born and first-generation participants had higher E/e' but lower LAVI and e' velocities compared with the second generation. Higher acculturation and income &gt;20K were associated with higher LVMI, LAVI and E/e' but lower e' velocities. Preferential Spanish-speakers with an income <20K had a higher E/e'. CONCLUSIONS:Acculturation was associated with abnormal cardiac structure and function, with some effect modification by socioeconomic status

NMR h3 JNC’ Couplings Provide Comprehensive Geometrical Constraints for Protein H-bonds in Solution

Protein backbone H-bonds (>N–H···O–C<) show relationships between NMR h3JNC\u27 couplings measured in solution and H-bond geometry parameters seen in X-ray crystal structures. Assuming that the solution and crystal structure of protein backbone is the same, the h3JNC\u27 couplings can be calibrated to provide good estimates of both angular and radial H-bond parameters in a solution. The crucial premise of equality between the solution and the crystal structure of protein backbone we validated on the level of the NH-bonds orientation, by comparing the orientations inferred from X-ray crystal structures with the solution ones determined from NMR residual dipolar couplings

Association Between Age, Gender and Body Weight in Educational Institutions in Ota, Southwest Nigeria

Background and Objective: There is paucity of data on the association between body weight and age or gender in Nigeria. This study investigated the body weight distribution amongst sexes and different age groups in educational institutions in Ota, Southwest Nigeria. Materials and Methods: The participants, 1394 (609%; 785&) healthy persons, were randomly selected from four schools in Canaanland, Ota and divided into six age groups: 2-5, 6-12, 13-19, 20-39, 40-59 and 60-75 years. Body weight was categorized into normal weight, underweight, overweight and obesity using CDC age and sex-specific BMI cut-offs for 2-19 years and WHO cut-offs for 20 years and above. Strength of association was assessed by correlation and regression analyses. Results: Underweight was prevalent at early childhood (22.7%) whereas obesity was predominant at middle adulthood (26.4%). Correlation was strong (p<0.001) between age and the anthropometric parameters: Weight (0.696); height (0.317); BMI (0.612) and body weight category (0.200). Gender had significant correlation with weight (-0.314, p<0.001) and height (-0.056, p<0.005). Body weight correlated more with age compared to gender. Conclusion: Age and gender had significant influence on the body weights of the studied population and could be factored into the national scheme for health and nutritional improvement
