IGC Proceedings (1977-2023)

Net Primary Productivity (NPP) of grassland is a key variable of terrestrial ecosystems and is an important parameter for characterizing carbon cycles in grassland ecosystems. In this research, the Inner Mongolia grassland NPP was calculated using the Miami Model and the impact of climate change on grassland NPP was subsequently analyzed under the Special Report on Emissions Scenarios (SRES) A2, B2, and A1B scenarios, which are inferred from Providing Regional Climates for Impacts Studies (PRECIS) climate model system. The results showed that: (1) the NPP associated with these three scenarios had a similar distribution in Inner Mongolia: the grassland NPP …

Tithonia Diversifolia For Ruminant Nutrition, Rogerio M. Mauricio, Rafael S. Ribeiro, Sylvia R. Silveira, Person L. Silva, Leonardo Calsavara, Luiz G. R. Pereira, Domingos S. C. Paciullo

IGC Proceedings (1977-2023)

India and Brazil lead the world ranking of livestock enteric methane emissions (FAO 2006). According to FAO (2006), Brazil (9.6 Tg of CH4/year) is the highest emitter of methane from cattle, followed by India (8.6 Tg of CH4/year) and the USA (5.1 Tg of CH4/year). In livestock, methane (CH4) formed from enteric fermentation of carbohydrates is primarily responsible for the emissions in the sector. Regarding livestock methane emission, Delgado et al. (2012) evaluated 20 tree and shrub species using in vitro technique and demonstrated a reducing effect on the amount of methane when Tithonia diversifolia was compared with, for …

Herbage Intake, Methane Emissions And Animal Performance Of Steers Grazing Dwarf Elephant Grass With Or Without Access To Arachis Pintoi Pastures, Ederson A. De Andrade, Henrique M. N. Ribeiro-Filho, Diego M. De Liz, João G. R. Almeida, Marcolino F. Miguel, Gutierri T. Raupp, Fabiana R. Ramos, Edison X. Almeida

IGC Proceedings (1977-2023)

The inclusion of legumes in diets based on grass has nutritional benefits due to ingestive and digestive interactions (Niderkorn and Baumont 2009). Moreover, it is speculated that tropical legumes can contribute to reducing the emission of greenhouse gases (GHG) compared to diets exclusively composed of grasses (Archimède et al. 2011). However, under grazing conditions, these advantages are not always possible to obtain. This occurs when the spatial distribution of sward grasses impose limitations on access to legumes by grazing animals (Solomon et al. 2011). This can be the case, for example, when legumes are overlapped by the leaves …

Effect Of Grazing On Soil Carbon And Nitrogen In Alpine Madow, Eastern Of Tibetan Plateau, Shiqing Li, Zhenggang Guo, Xue Ran, Yuying Shen

IGC Proceedings (1977-2023)

As the grassland ecosystem in the Tibetan Plateau is very fragile, overgrazing likely leads to more serious damages to it than other ecosystems. In the past 30 years, 37% of the alpine meadows have been heavily damaged by grazing causing degradation of native vegetation, a decline in species richness and feed value, and more seriously soil erosion (Six et al. 2004). The impact of grazing on alpine grasslands appears to be hysteresis, as the soil needs more time to recover than the vegetation. So analysing the effect of grazing intensity on soil characteristics is an important way to reveal how …

Is There Genetic Diversity In The ‘Leucaena Bug’ Synergistes Jonesii Which May Reflect Ability To Degrade Leucaena Toxins?, Jagadish Padmanabha, Michael J. Halliday, Stuart E. Denman, Carl K. Davis, H. Max Shelton, Chris S. Mcsweeney

IGC Proceedings (1977-2023)

Leucaena leucocephala, a nutritionally rich forage tree legume, contains a non-protein amino acid, mimosine, which is degraded by ruminal bacteria to toxic metabolites 3,4-DHP and 2,3-DHP resulting in goitre-like symptoms in animals, severely restricting weight gain. Raymond Jones, in the early 1980s, discovered the ‘leucaena bug’ in the rumen of goats in Hawaii that degraded these toxic DHP metabolites into non-toxic compounds (Jones and Lowry 1984) which was named Synergistes jonesii (Allison et al. 1992) Subsequently, a rumen inoculum containing S. jonesii was used as an ‘oral drench’ for cattle, kept in continuous culture (Klieve et al. …

Rates Of Urinary Toxin Excretion In Unprotected Steers Fed Leucaena Leucocephala, Joseph H. O’Reagain, Sam R. Graham, Scott A. Dalzell, H. Max Shelton

IGC Proceedings (1977-2023)

Leucaena (Leucaena leucocephala) is a productive, nutritious, leguminous forage tree with high capacity for ruminant live weight gain. The plant does however contain the non-protein amino acid mimosine which is degraded within the rumen to 3-hydroxy-4(1H)-pyridone (3,4-DHP) with potential to cause adverse effects on animal health and production. Stock can be protected via rumen inoculation with the bacterium Synergistes jonesii, which is capable of degrading the toxin. However surveys have demonstrated sub-clinical toxicity is persisting in Queensland herds (Dalzell et al. 2012).

Currently, testing for toxicity involves analysis of urine samples using high performance liquid chromatography …

Prevalence Of Dhp Toxicity And Detection Of S. Jonesii In Ruminants Consuming Leucaena Leucocephala In Eastern Indonesia, Michael J. Halliday, Tanda Panjaitan, Jacob Nulik, H. Dahlanuddin, Jagadish Padmanabha, Chris S. Mcsweeney, Sulaiman Depamede, Debora Kana Hau, Kurniawan, Muhammad Fauzan, Sutartha, Baiq Tutik Yuliana, Charles Pakereng, Putri Ara, Dessy Liubana, Resti G. Edison, H. Max Shelton

IGC Proceedings (1977-2023)

Leucaena leucocephala (leucaena) is a productive forage tree legume widely used in eastern Indonesia. While highly nutritious, it possesses the toxin mimosine which adversely affects animal production. In ruminants, mimosine is readily converted to the two isomers of dihydroxypyridine (3,4-DHP and 2,3-DHP) known to cause goitre, suppress appetite, and cause severe mineral deficiencies. These adverse symptoms may be partially responsible for the reluctance of some farmers to feed leucaena.

A bacterium capable of complete degradation of DHP, Synergistes jonesii, originally discovered in Hawaii in goats consuming leucaena (Jones and Megarrity 1986), was later found in Indonesia which led to …

The Efficacy Of In Vitro Synergistes Jonesii Inoculum In Preventing Dhp Toxicity In Steers Fed Leucaena-Grass Diets, Michael J. Halliday, Hayley E. Giles, Scott A. Dalzell, Chris S. Mcsweeney, H. Max Shelton

IGC Proceedings (1977-2023)

Leucaena leucocephala (leucaena) is a valuable forage tree legume for tropical animal production that contains the toxin mimosine. The breakdown products of mimosine in ruminants (3,4-DHP and 2,3-DHP) can adversely affect their health and limit weight gains (Jones and Hegarty 1984). The rumen bacterium Synergistes jonesii, introduced into Australia in 1983 was shown to completely and rapidly degrade these toxins to safe levels (Jones and Megarrity 1986). Since 1996, an in vitro produced inoculum has been made commercially available to Australian graziers (Klieve et al. 2002). Accordingly, the issue of leucaena toxicity in Australia was thought to be …

Astronauts on interplanetary missions - such as to Mars - will be exposed to space radiation, a spectrum of highly-charged, fast-moving particles that includes ⁵⁶Fe and ²⁸Si. Earth-based preclinical studies show space radiation decreases rodent performance in low- and some high-level cognitive tasks. Given astronaut use of touchscreen platforms during training and space flight and given the ability of rodent touchscreen tasks to assess functional integrity of brain circuits and multiple cognitive domains in a non-aversive way, here we exposed 6-month-old C57BL/6J male mice to whole-body space radiation and subsequently assessed them on a touchscreen battery. Relative to …

Change Of Behavior Of Bos Grunniens In The Alpine Rangeland In The Eastern Tibetan Plateau, Nobumi Hasegawa, Rende Song, Guomei Li, Xumin Cao, Masahiro Tasumi, Sachiko Idota, Akira Fukuda

IGC Proceedings (1977-2023)

Over 6 million yaks (Bos grunniens) are grazed in the alpine rangelands of the eastern Tibetan Plateau in Qinghai Province, China. Degradation of rangelands has been caused by increased numbers of domestic animals following the rise of the human population. In our previous study in northern and southern sites of Tibetan Plateau in Qinghai Province from 2003 to 2006, behavior of yaks and chemical composition of the faeces (Hasegawa et al. 2006; Hasegawa et al. 2008) and vegetation (Li et al. 2006; Song et al. 2006) were investigated and compared between the two sites, …

Three themes emerged, including knowledge of health insurance options and benefits information, affordability, and unmet expectations. These findings show the need for higher education institutions to develop a plan to integrate international students …

Some Pasture Changes In The Eastern Steppe Of Mongolia, Dorjgotov Ariungerel, Ts Ouyntsetseg

IGC Proceedings (1977-2023)

Significant vegetation changes have been recorded in Mongolian steppe types such as Speargrass-Cleistogenes, Cleistogenes-Forbs and Filifolim sibiricum-Speargrass and these changes have been attributed to climate factors rather than human activity. Species dominance in those pasture types exhibited change that was linearly related to the degradation ratio. For example, Speargrass, which is a dominant species in the steppe and is seen as a preferred species for building sustainable grasslands, is slowly losing dominance in the eastern steppe grassland type due to heavy degradation and is replaced by a range of sedges. During the years of this study …

Lymphocytes infiltrate the stroke core and penumbra and often exacerbate cellular injury. B cells, however, are lymphocytes that do not contribute to acute pathology but can support recovery. B cell adoptive transfer to mice reduced infarct volumes 3 and 7 d after transient middle cerebral artery occlusion (tMCAo), independent of changing immune populations in recipient mice. Testing a direct neurotrophic effect, B cells cocultured with mixed cortical cells protected neurons and maintained dendritic arborization after oxygen-glucose deprivation. Whole-brain volumetric serial two-photon tomography (STPT) and a custom-developed image analysis pipeline visualized and quantified poststroke B cell diapedesis throughout the brain, including …

Agroecosystem Health Cards: A Practical Tool For Sustainable Management Of Grasslands, Iker Mijangos, Isabel Albizu, Mikel Anza, Iker Martin, Sorkunde Mendarte, Lur Epelde, Carlos Garbisu

IGC Proceedings (1977-2023)

The traditional grazing activity carried out for centuries in mountainous areas of the Basque Country (Northern Atlantic Spain) facilitated the presence of different extensive pasture habitats, such as those included in the Gorbeia Natural Park and surrounding valleys (43° 02’N, 2° 49’W). Currently, these pastures are highly valued due to the ecosystem services they provide. In this context, one of the main objectives of the LIFE-SOILMONTANA project (ref. LIFE 10 NAT/ES/579) is to develop a practical tool that allows grassland managers (farmers, scientists and authorities) to auto-evaluate the suitability of alternative agronomic practices in relation to the conservation of these …

The aim of Community Pasture Management Plans is to decrease risks of reducing pasture quality and to raise pasture resource use sustainability. One of the important parts of a pasture management plan is pasture health assessment. The objective of our work was to develop a rapid and simple technique to assess pasture health for community members and other land managers who live or work on pastures. This tool is the result of a collaborative effort of scientists from different countries. This technique utilizes 6 indicators, which are …

Using Participatory Research, Remote Sensing And Field Surveys To Build A State And Transition Model For The Native Pastures Of Northern Uruguay, Marcelo Pereira Machín

IGC Proceedings (1977-2023)

Native grasslands cover 55% of the agricultural lands of Uruguay. Balancing conservation, agricultural production and human well-being is a major management challenge. Adaptive management approaches have been developed for leased land, underpinned by a newly developed state and transition model (STM). The model was tested in northern Uruguay, in the Department of Paysandú, covering an area of 8300 ha. Floristic surveys were used to define five states, based on the relative cover of key plant species and functional types. Each state was characterized in terms of livestock density, sheep/cattle ratio and years since last ploughing. Aboveground Net Primary Production (ANPP) …

Productive Performance Of Growing Cattle Grazing A Silvopastoral System With Leucaena Leucocephala, R. Mayo-Eusebio, M. P. Utrilla-García, C. F. Aguilar-Pérez, Francisco J. Solorio-Sánchez, A. J. Ayala-Burgos, Eduardo G. Briceño-Poot, Luis Ramírez-Avilés, Juan C. Ku-Vera

IGC Proceedings (1977-2023)

In tropical regions, the feeding of cattle is usually based on the grazing of medium to low quality grasses. Low fertility of soils, changing climatic conditions and the poor management of pastures, have further reduced the quality and forage yield of pastures. The low availability and quality of grasses gives modest weight gains for grazing cattle and this in-turn causes low economical efficiency of cattle production systems (Campos et al. 2011). Silvopastoral systems represent a sustainable option for meat and milk production in the tropics. The association of grasses with legumes such as Leucaena leucocephala (leucaena) supply forage with …

Hierarchical Clustering Analyses Of Plasma Proteins In Subjects With Cardiovascular Risk Factors Identify Informative Subsets Based On Differential Levels Of Angiogenic And Inflammatory Biomarkers, Zachary Winder, Tiffany L. Sudduth, David W. Fardo, Qiang Cheng, Larry B. Goldstein, Peter T. Nelson, Frederick A. Schmitt, Gregory A. Jicha, Donna M. Wilcock

Sanders-Brown Center on Aging Faculty Publications

Agglomerative hierarchical clustering analysis (HCA) is a commonly used unsupervised machine learning approach for identifying informative natural clusters of observations. HCA is performed by calculating a pairwise dissimilarity matrix and then clustering similar observations until all observations are grouped within a cluster. Verifying the empirical clusters produced by HCA is complex and not well studied in biomedical applications. Here, we demonstrate the comparability of a novel HCA technique with one that was used in previous biomedical applications while applying both techniques to plasma angiogenic (FGF, FLT, PIGF, Tie-2, VEGF, VEGF-D) and inflammatory (MMP1, MMP3, MMP9, IL8, TNFα) protein data to …

Integrating Beef And Cotton Production Reduces Irrigation Needs In The Texas Southern High Plains, C. Philip Brown, V. G. Allen, Rick Kellison, P. Green, C. J. Zilverberg, P. Johnson, V. Acosta-Martinez, C. P. West

IGC Proceedings (1977-2023)

The Texas High Plains is a semiarid agricultural region located in the central south plains of the United States. This area exemplifies semiarid regions where water is becoming scarce. Crop production depends heavily on irrigation primarily from the Ogallala aquifer at non-sustainable rates of use. Irrigated monoculture cotton (Gossypium hirsutum L.) is the dominant crop but grazing livestock in this once vast grassland is re-emerging as the aquifer declines. Environmental benefits of integrated crop and livestock systems have been suggested. We compared a cotton monoculture with an integrated cotton-forage-beef stocker steer system over 10 yr to determine effects on …

The aim of this study was to determine whether racial differences in HbA1c persist in older adults (≥65 years) living with type 2 diabetes. Data from The National Health and Nutrition Examination Survey (NHANES) 2003-2014 were used to examine the association between HbA1c and older adults (≥65 years) over time. Compared to non-Hispanic Whites, Mexican Americans had the greatest difference in average HbA1c among minority groups, followed by those with unspecified/mixed ethnicities and non-Hispanic Blacks. In the adjusted linear model, racial minorities had a statistically significant relationship with HbA1c. There was no relationship between HbA1c and older age and insulin …

Rivastigmine Modifies The Α-Secretase Pathway And Potentially Early Alzheimer's Disease, Balmiki Ray, Bryan Maloney, Kumar Sambamurti, Hanuma K. Karnati, Peter T. Nelson, Nigel H. Greig, Debomoy K. Lahiri

Sanders-Brown Center on Aging Faculty Publications

Rivastigmine (or Exelon) is a cholinesterase inhibitor, currently used as a symptomatic treatment for mild-to-moderate Alzheimer’s disease (AD). Amyloid-β peptide (Aβ) generated from its precursor protein (APP) by β-secretase (or BACE1) and γ-secretase endoproteolysis. Alternative APP cleavage by α-secretase (a family of membrane-bound metalloproteases– Adamalysins) precludes the generation of toxic Aβ and yields a neuroprotective and neurotrophic secreted sAPPα fragment. Several signal transduction pathways, including protein kinase C and MAP kinase, stimulate α-secretase. We present data to suggest that rivastigmine, in addition to anticholinesterase activity, directs APP processing away from BACE1 and towards α-secretases. We treated rat neuronal PC12 cells …

Hsp47 Promotes Cancer Metastasis By Enhancing Collagen-Dependent Cancer Cell-Platelet Interaction, Gaofeng Xiong, Jie Chen, Guoying Zhang, Shike Wang, Kunito Kawasaki, Jieqing Zhu, Yan Zhang, Kazuhiro Nagata, Zhenyu Li, Binhua P. Zhou, Ren Xu

Markey Cancer Center Faculty Publications

Increased expression of extracellular matrix (ECM) proteins in circulating tumor cells (CTCs) suggests potential function of cancer cell-produced ECM in initiation of cancer cell colonization. Here, we showed that collagen and heat shock protein 47 (Hsp47), a chaperone facilitating collagen secretion and deposition, were highly expressed during the epithelial-mesenchymal transition (EMT) and in CTCs. Hsp47 expression induced mesenchymal phenotypes in mammary epithelial cells (MECs), enhanced platelet recruitment, and promoted lung retention and colonization of cancer cells. Platelet depletion in vivo abolished Hsp47-induced cancer cell retention in the lung, suggesting that Hsp47 promotes cancer cell colonization by enhancing cancer cell–platelet interaction. …
