Turkish Journal of Veterinary & Animal Sciences

Plant-derived polysaccharides have been reported for diverse biological response modification (BRM) and immunotherapeutic (IT) activities in animals by activating their defense systems to perform better immunogenically against invading pathogens. Keeping this in view, this study was conducted to assess the BRM and IT activities of barley (Hordeum vulgare L.)-derived arabinoxylans (AXs) against coccidiosis in broilers. Significantly enhanced (P < 0.05) in vivo and in vitro lymphoproliferative responses to T-cell mitogens were revealed in broilers administered barley AXs when compared to the control group. Humoral immune response in terms of antibody titers against sheep erythrocytes was also found higher (P < 0.05) in AX-administered chickens. Furthermore, AX-administered chickens also showed higher weekly weight gains and improved feed conversion ratios as compared to controls. Results of the challenge experiment showed that the percentage of protection and daily weight gains were statistically higher (P < 0.05) whereas mean oocysts per gram of droppings and lesion scores were significantly lower (P < 0.05) in the chickens administered barley AXs as compared to controls. In conclusion, barley-derived AXs led to better growth performance and elicited humoral and cellular immune responses in commercial broilers that persisted against coccidial infection in broiler chickens.

N-Terminal And Central Domains Of Apc Function To Regulate Branch Number, Length And Angle In Developing Optic Axonal Arbors In Vivo, Taegun Jin, Gregory Peng, Esther Wu, Shrey Mediratta, Tamira Elul

Faculty Publications & Research of the TUC College of Osteopathic Medicine

During formation of neuronal circuits, axons navigate long distances to reach their target locations in the brain. When axons arrive at their target tissues, in many cases, they extend collateral branches and/or terminal arbors that serve to increase the number of synaptic connections they make with target neurons. Here, we investigated how Adenomatous Polyposis Coli (APC) regulates terminal arborization of optic axons in living Xenopus laevis tadpoles. The N-terminal and central domains of APC that regulate the microtubule cytoskeleton and stability of β-catenin in the Wnt pathway, were co-expressed with GFP in individual optic axons, and their terminal arbors were …

Ecological Uncertainty Influences Vigilance As A Marker Of Fear, Laurence E. A. Feyten, Grant E. Brown Jan 2018

Ecological Uncertainty Influences Vigilance As A Marker Of Fear, Laurence E. A. Feyten, Grant E. Brown

Animal Sentience

We expand on the factors that may shape the predictability of risk and the potential impacts on the links between vigilance and fear, primarily in aquatic prey communities. Uncertainty in predation risks has been shown to induce increased levels of neophobia among prey. As a result of this phenotypically plastic response, prey are faced with risk assessment cues that may vary widely in their reliability. We argue that decomposing predictability may provide useful insights into the relationship between vigilance and fear.

Remobilization Of Heavy Metals By Mangrove Leaves, Hanan Almahasheer, Oscar Serrano, Carlos M. Duarte, Xabier Irigoien Jan 2018

Remobilization Of Heavy Metals By Mangrove Leaves, Hanan Almahasheer, Oscar Serrano, Carlos M. Duarte, Xabier Irigoien

Research outputs 2014 to 2021

Several studies have been carried out on heavy metal pollution in mangrove ecosystems. However, the role of mangroves in heavy metal remobilization is still relatively unknown. On one side, mangrove woody organs and soils sequester heavy metals for long time periods, but on the other hand, senescence of mangrove leaves may return these metals collected by roots to the upper layers of the soil. Here, we analyzed the concentration of chemical elements (Al, As, Cd, Cr, Cu, Fe, Mn, Mo, Ni, Pb, Sr, V, and Zn) as a function of age in mangrove leaves to understand heavy metals retention by …

The Dexing Copper Mine is one of the largest copper mines in Asia, but few studies have reported the soil fauna community composition after revegetation. This study investigated the influence of revegetation on the soil fauna communities and structures in three vegetation restoration models (designated as I, II, and III) and in a sample without revegetation (IV) in two tailings pools of Dexing Copper Mines 1 and 2 using modified Tullgren and Baermann methods. A total of 548 individuals were collected, which belonged to 5 classes, 7 orders, 3 suborders, and 19 families. The individuals, groups, and diversity of the …

This study was conducted to investigate the influence of tree thinning on habitat variables and small rodents in a natural deciduous forest in South Korea. We focused on the populations of the small forest-dwelling rodents, striped field mouse Apodemus agrarius and Korean field mouse A. peninsulae. Populations were monitored for 2 years in a natural deciduous forest subject to tree thinning. The coverage of ground vegetation and number and volume of downed trees were significantly increased after thinning. However, the coverage of overstory and understory vegetation and number of standing trees were decreased in postthinning session. The abundance and survival …
