Intercropping of maize and climbing bean: fodder yield, quality and nutrient compositio... - 1 views

  •  
    A study was conducted to examine fodder yield and silage quality of maize (Zea mays L.) and climbing bean (Phaseolus vulgaris L.) intercropping with different planting structure. Maize was cultivated alone and intercropped with climbing bean as follows;1 row maize to 1 row climbing bean (1M1K), 1 row maize to 2 rows climbing bean (1M2K) and 2 rows maize to 1 row climbing bean (2M1K). The experiment was laid out in randomized complete block design with four treatments and three replications. The crops were harvested when the maize reached at milk stage and climbing bean at R7 stage. The results indicated significant increase in fresh biomass and dry matter production of maize fodder alone as compared to maize intercropped with climbing bean fodder. However, no difference (p>0.05) was observed in ether extract (EE), and ash (%) of nutrient composition of fodder among the four treatments After 45 days of ensiling period, silage samples were analysed for pH, organic acids (lactic, acetic, and butyric), ammonia-N(NH3-N), dry matter (DM), crude protein (CP), ether extract (EE), neutral detergent fibre (NDF), acid detergent fibre (ADF), water soluble carbohydrate (WSC), calcium (Ca), sodium (Na) and potassium (K). All intercropped silages had higher CP values (1M1K, 12.0%; 1M2K, 12.3%; 2M1K, 11.1%) than the monocrop maize (SM, 8.9%) silage. Higher organic acids and ammonia-N (p<0.05) were produced in the 1M2K silages as compared to others silages. The study showed that among all intercropped silages the 1M2K (1 row maize to 2 rows climbing bean) was preferable according to nutrient composition than other intercropped silages.

MPG Nod2 is essential for temporal development of intestinal microbial communities. - 0 views

  •  
    "We found that adult Nod2-deficient mice display a substantially altered microbial community structure and a significantly elevated bacterial load in their faeces and terminal ileum compared to their wild-type counterparts. Interestingly, we demonstrate that these findings are also present in weaning mice, indicating a profound influence of Nod2 on the early development and composition of the intestinal microbiota. We demonstrate that NOD2 genotypes also influence the microbial composition in humans. Conclusions Our results point to an essential role of Nod2 for the temporal development and composition of the host microbiota, both in mice and in humans, which may contribute to the complex role of NOD2 for the aetiopathogenesis of Crohn's disease.

Metal foam obliterates bullets - and that's just the beginning - 20 views

  •  
    Composite metal foams (CMFs) are tough enough to turn an armor-piercing bullet into dust on impact. Given that these foams are also lighter than metal plating, the material has obvious implications for creating new types of body and vehicle armor - and that's just the beginning of its potential uses.

Seasonal effects on suicide rates - Wikipedia, the free encyclopedia - 0 views

  •  
    "These findings clearly state that there is a relationship between summer suicide rates and biochemical (e.g., plasma L-TRP and melatonin levels, [3H]paroxetine binding to blood platelets), metabolic (serum total cholesterol, calcium and magnesium concentrations), and immune (number of peripheral blood lymphocytes and serum sIL-2R) variables.[18] Another study focused on the association between depression, suicide, and the amount of polyunsaturated fatty acids (PUFA). They state that "depression is accompanied by a depletion of n-3 poly-unsaturated fatty acids".[22] Their methodology involved taking periodic blood samples-every month for one year-of healthy volunteers, allowing them to analyze the "PUFA composition in serum phospholipids and [relating] those data to the annual variation in the mean weekly number of suicides". They used an analysis of variance (ANOVA) to document their results, finding that PUFA like arachidonic acid, eicosapentaenoic acid, and docosahexaenoic acid all occurred at significantly lower rates in winter than in summer months. The association between depression, suicide, and PUFA rates is indicative of there being a biological factor in seasonal effects on suicide rates"

Christina Zielinski: With the Immune System's Weapons - 0 views

  •  
    "When the right microorganisms are at work, immune cells involved in the development of autoimmune illnesses like psoriasis, multiple sclerosis and arthritis, can develop anti-inflammatory properties. Scientists at Charité - Universitätsmedizin Berlin and the Institute for Research in Biomedicine, Bellinzona, Switzerland, have now made this discovery. Their work is published in the current issue of the scientific journal Nature*. The scientists were able to prove that particular fungi activate the immune cells involved in the development of certain illnesses, whereas other microorganisms, in particular bacteria that are found naturally on our skin, lend an anti-inflammatory function to them. "This not only demonstrates that the composition of our microflora has a decisive role in the development of chronic illnesses, but also that the key cells causing illness can develop an anti-inflammatory 'twin'," explained Dr. Christina Zielinski, first author of the study."

Hachung Chung Species-Specific Microbes May Be Key to a Healthy Immune System: Scientif... - 0 views

  •  
    "Mice have a jungle of bacteria, viruses and fungi in their stomachs-and so do we. These microorganisms help both mice and us break down dinner. As we are finding, these bugs also help to regulate the immune system. But we are just starting to learn how these tiny organisms influence us and how changing their composition changes us... Interestingly, though, the mice with these microbes did not: their immune systems remained underdeveloped. Even when researchers gave rat microbiota to mice, the mice's immune systems failed to mature"

Enterotypes of the human gut microbiome : Nature : Nature Publishing Group - 0 views

  •  
    "Our knowledge of species and functional composition of the human gut microbiome is rapidly increasing, but it is still based on very few cohorts and little is known about variation across the world. By combining 22 newly sequenced faecal metagenomes of individuals from four countries with previously published data sets, here we identify three robust clusters (referred to as enterotypes hereafter) that are not nation or continent specific. We also confirmed the enterotypes in two published, larger cohorts, indicating that intestinal microbiota variation is generally stratified, not continuous. This indicates further the existence of a limited number of well-balanced host-microbial symbiotic states that might respond differently to diet and drug intake."

Is dark matter mostly 'dark atoms'? - physicsworld.com - 0 views

  •  
    Physicists currently believe that most of the dark matter in the universe is made up of individual particles, and the challenge is to work out what kind of particles these are. New research, however, overturns this assumption and says that observational and experimental data are better explained if dark matter exists as composite particles - atoms of dark protons and dark electrons that are acted on by the dark-matter equivalent of the electromagnetic force.

Diversity of plant parasitic nematodes associated with common beans (Phaseolus vulgaris... - 0 views

  •  
    Common beans (Phaseolus vulgaris L.) are the most important legume staple food in Kenya coming second to maize. In Central Highlands of Kenya, the 0.4-0.5ton ha-1 output is below the genetic yield potential of 1.5-2ton ha-1 partly due pests and diseases. Plant parasitic nematodes (PPN) have been reported to cause yield losses of up to 60% on beans. Though bean production is important in the Central highlands of Kenya, information on PPN associated with the beans in the region is lacking. This study was therefore undertaken to establish the diversity of PPN associated with common beans and to assess the root knot nematode damage on beans in the region. The study covered 50 farms (32 in Kirinyaga and 18 in Embu Counties) distributed in eight localities namely Kibirigwi (L1), Makutano (L2), Kagio (L3), Mwea (L4) and Kutus (L5) in Kirinyaga County and Nembure (L6), Manyatta (L7) and Runyenjes (L8) in Embu County and covering three Agro Ecological Zones (AEZs); UM2 (L1, L2, L3 & L4), UM3 (L5, L7 & L8) and UM4 (L6) AEZs. Manyatta (L7) and Nembure (L6), had the highest and second highest gall indices, respectively, while Kibirigwi (L1), Makutano (L2) and Mwea (L4) had some of the lowest gall indices. The most common PPN in bean roots were Meloidogyne spp. Pratylenchus spp. and Scutellonema spp. with a frequency of 94.38%, 78.25% and 59.13%, respectively. This further confirm the importance of these nematodes in bean production systems. Upper Midland 3 (UM3) AEZs and UM4 had higher nematode population densities and diversity than UM2. Disease severity and nematode composition and distribution were notably low in the irrigated areas Kibirigwi, Kagio and Mwea compared to rain-fed areas such as Makutano, Nembure and Manyatta.
