1. Restriction of food to ewes bearing twin lambs showed a trend to decrease the level of omega 6 fatty acids in muscle phospholipids of the foetus though this was not significant statistically (P less than 0.05). 2. There was a significant increase in the fatty acid ratio, 20:3 omega 9:20:4 omega 6 in the twin lambs as compared with single lambs. 3. There were no symptoms of polyunsaturated fa...
One serious concern of health policymakers in South Africa is the fact that there is no national data on the dietary intake of adult South Africans. The only national dietary study was done in children in 1999. Hence, it becomes difficult to plan intervention and strategies to combat malnutrition without national data on adults. The current review consequently assessed all dietary studies in ad...
Undernutrition--protein energy malnutrition or specific nutrient deficiencies--has been an inherent characteristic of impoverished populations throughout the world. Over-nutrition, obesity and nutrition imbalance is a current concern among those with rising though still insufficient incomes. We review data to suggest that the prevalence of these forms of malnutrition in populations is highly in...
BACKGROUND Regular fish and omega-3 consumption may have several health benefits and are recommended by major dietary guidelines. Yet, their intakes remain remarkably variable both within and across populations, which could partly owe to genetic influences. OBJECTIVE To identify common genetic variants that influence fish and dietary eicosapentaenoic acid plus docosahexaenoic acid (EPA+DHA) c...
Efficiency of 6-ethynylpyridone (E), a potential thymine (T) analogue, which forms high-fidelity base pairs with adenine (A) and gives rise to stabler DNA duplexes, with stability comparable to those containing canonical cytosine(C):guanine(G) base pairs, has been reported recently. Estimates of the interaction energies, involving geometry optimization at the DFT level (including middle range d...
1. The fluorescent ATP analogue 1,N6-etheno-ATP is a good substrate and an efficient allosteric inhibitor of rabbit skeletal-muscle phosphofructokinase. 2. Fluorescence energy transfer occurs between bound 1,N6-etheno-ATP and phosphofructokinase. 1,N6-Etheno-ATP fluorescence is enhanced, intrinsic protein fluorescence is quenched, and the excitation spectrum of 1,N6-etheno-ATP fluorescence is c...
We define a conformally invariant action S on gauge connections closed pseudo-Riemannian manifold M of dimension 6. At leading order this is quadratic in the connection. The Euler-Lagrange equations S, with respect to variation connection, provide higher-order analogue (source-free) Yang-Mills equations. For any connection A M, we S(A) by first defining Lagrangian density associated A. This not...
Following Brown [1] , we construct composite operators for the scalar ϕ 3 theory in six dimensions using renormalisation group methods with dimensional regularisation. We express bare terms of renormalised lower dimension, then do this traceless tensor operators. energy momentum operators, some having divergent coefficients. subtract these away and obtain a manifestly finite tensor. The subtrac...
Despite suggestions that animal pollinators are crucial for human nutritional health, no studies have actually tested this claim. Here, we combined data on crop pollination requirements, food nutrient densities, and actual human diets to predict the effects of pollinator losses on the risk of nutrient deficiency. In four developing countries and across five nutrients, we found that 0 to 56% of ...
