Wildlife populations are in decline due to human threats, including highways. Strategies for reducing road impacts on wildlife include wildlife fencing which keep animals off roads and wildlife crossing structures (WCSs) which provide safe passage across roads. Wildlife crossing structures are diverse and transportation managers are often interested in identifying which WCS designs are effective for target species so a model that predicts target species usage of WCSs is likely to be beneficial to managers and biologists. Wildlife crossing structures are typically built for select species but are utilized by other species, so it may be beneficial to examine WCS …

Metastatic uveal melanomas are highly resistant to all existing treatments. To identify actionable vulnerabilities, we conducted a CRISPR-Cas9 knockout screen using a library composed of chromatin regulators. We revealed that the lysine methyltransferase, SETDB1, plays a critical role in metastatic uveal melanoma cell proliferation and survival. Functionally, SETDB1 deficiency induces a DNA damage response, senescence-like state and growth arrest. Knockdown of SETDB1 is associated with a decreased expression of genes related to replication and cell cycle. Moreover, deficiency in CDC6, an essential regulator of DNA replication, phenocopies SETDB1 inhibition. Using a pre-clinical model, we further demonstrated that anti-SETDB1 therapy impairs …

Leptin, a hormone primarily secreted by adipocytes, regulates energy balance and systemic metabolism through its interaction with the leptin receptor (LEPR). Beyond these functions, leptin signaling has been implicated in the pathogenesis of tissue fibrosis. Here, we report the x-ray crystal structures of a leptin-neutralizing antibody (hLep3) in the unbound and leptin-bound states. The interaction of this antibody with leptin mimics the interaction of the LEPR with leptin, providing direct insights into the mechanism by which the antibody disrupts leptin signaling. We furthermore evaluate the therapeutic potential of neutralizing leptin with this antibody across distinct mouse models of fibrosis affecting …

Using An Old Assay In New Ways: Differential Scanning Calorimetry Characterization, Quantification, And Interaction Analysis Of Whey Proteins, Charity Conlin Jennings
Theses and Dissertations
Whey proteins including β-Lactoglobulin, α-Lactalbumin, Immunoglobulin-G, Serum Albumin, Lactoferrin, and Lactoperoxidase each have unique biological properties spanning anti-bacterial, anti-fungal, and anti-viral activities as well as deliver essential nutrients to the human body. In the past decade, there has been a large focus on extracting these individual proteins for their use in foods and supplements. In order to best extract these proteins and prepare them properly in foods and supplements, an understanding of how they behave and denature in different environments is necessary. However, there is insufficient knowledge of their thermodynamic properties and potential interactions in varying conditions. Additionally, there are …

Onchocerciasis remains a significant cause of morbidity and economic loss in sub-Saharan Africa. Despite the existence of effective therapeutics, a prophylactic vaccine targeting the etiologic agent, Onchocerca volvulus, is needed to control ongoing disease and transmission. Mice were vaccinated against O. volvulus with a fusion of the recombinant antigens Ov-103 and Ov-RAL-2 (Ov-FUS-1) with Advax-CpG adjuvant. Immunized mice developed protective immunity with the killing of third-stage larvae (L3) within 36 h of challenge infection. IgG from immunized mice passively transferred protective immunity to naïve mice, indicating that antigen-specific IgG mediated parasite elimination. Neutrophils were the most abundant subset of immune …

The intestinal mucosal epithelium forms a barrier between luminal contents and the body. MicroRNAs (miRNAs) regulate mucosal homeostasis by controlling inflammatory responses and structural integrity. Here, we discovered a protective role for miR147 in intestinal inflammation using a miR147tdTomato reporter mouse. miR147 was enriched in the intestines, with the highest expression in the colonic epithelial cells at the luminal surface, with prominent expression in differentiated enterocytes. Mice with general or intestinal epithelial deletion of miR147 showed increased intestinal inflammation and diminished mucosal healing during colitis. RNA sequencing of miR147-deficient cells showed dysregulated immune signaling, with upregulated proinflammatory cytokine pathways and …

Developmental processes extend beyond embryogenesis to support lifelong tissue adaptations. Avian feather follicles, with their resident stem cells and capacity for cyclic regeneration, provide a dynamic model for postnatal tissue remodeling. Here, we propose the Mandarin duck (Aix galericulata) as an ideal model to study lifelong developmental modulation, focusing on the sexually dimorphic "sail feather"-a secondary flight feather in males that undergoes seasonal transformation into a strikingly asymmetric, ornamented phenotype during the breeding season. We identified asymmetric morphogen expression in regenerating male sail feathers and used transcriptome and H3K27ac ChIP-seq to uncover male and female signaling pathways and regulatory elements. …

IGC Proceedings (1977-2023)
Four tropical grasses and one legume were fertilized with O or 60 kg S/ha. Leaves and stems of 6 and 9 weeks old regrowth were harvested seperately from replicated plots and used to study the effect of S fertilization on parameters of in vitro DM and NDF digestion. The overall effect of fertilization was negative and most pronounced for leaves. There were large differences among forages. DM digestibility at 48 h was reduced (P < .05) for fertilized guinea grass and setaria but NDF digestion at 96 h was only lower for guinea grass. DM digestibility of stems was not affected by fertilization but NDF disappearance of napier grass stems was decreased significantly. S fertilization had no effect on lag of NDF digestion but rate of NDF digestion for stems and leaves was reduced (P < .05) by fertilization. The effect was especially large for centro. It is suggested that the negative effects of S fertilization are associated with changes in the structural components of the forages and the source of the rumen inoculum.

IGC Proceedings (1977-2023)
Four tropical grasses and one legume were grown on an oxic dystropept soil in W. Java, Indonesia. Two levels of S fertilizer were applied (0 and 60 kg S/ha). Forages were harvested at 6 and 9 week intervals during the wet and dry monsoons respectively. Production of leaves and stems was determined separately and samples of a 6- and 9-week regrowth were analyzed for chemical composition. The effect of S fertilization on dry matter (DM) yield was markedly influenced by the effect of season. During the wet season only the production of stems from napier grass was increased (P < .05). During the dry season stem and leaf production of napier grass and centro increased (P < .05) under fertilization but there was a decrease (P < .05) in leaf production of guinea grass. S fertilization increased S content in leaves and stems by 23%. There was a tendency for N to increase and for NDF in leaves to decrease. Only in centro was ADF and lignin of fertilized plants lower (P < .05). Although Ca, P, Mg, Cu and Zn were not affected by fertilization, ash content in leaves of fertilized forages differed (P < .05) from controls.

Only 600 000 hectares have been sown, or are naturalised, to these legumes, mainly to Townsville stylo (S. humilis). However, since 1974 anthracnose (Colletotrichum gloeosporioides) has severely affected Townsville stylo pastures, and newer cultivars of Stylosanthes are being used, viz: Verano (S. hamata), Seca and Fitzroy shrubby stylos (S. scabra) and Graham (S. guianensis var. guianensis). As little was known about the animal production and pasture stability associated with these stylos ( especially shrubby stylos) under …
Review Of Forage/Livestock Production On Mixed Farms In Sahel West Africa, James R. Dickey
Review Of Forage/Livestock Production On Mixed Farms In Sahel West Africa, James R. Dickey
IGC Proceedings (1977-2023)
This is a review of forage and livestock production as they interact with farming in Sahel West Africa. Because of the complementarity of livestock and farming, as well as the abundant production of native forage in the higher rainfall southern farming areas, there is considerable hope among the donor community and host governments that both livestock and crop production can be substantially increased in the Sudan zone of West Africa. According to Winrock (1978) crop residue provides 24 % of the world supply of ruminant nutrients .. On the other hand, livestock manure supplies a large part of the agricultural …
Forage Research In Morocco And Approach To Face Constraints In A Developing Country, G Jaritz, M Bounejmate
Forage Research In Morocco And Approach To Face Constraints In A Developing Country, G Jaritz, M Bounejmate
IGC Proceedings (1977-2023)
Forage production is of a iow level in Morocco because of socio-economic and technical constraints in spite of its potential functions to integrate animal husbandry into cropping systems and to prevent soil degradation. An approach to applied forage research is described which takes into account the existing constraints including the suboptimal functioning of the present extension service. It combines small plot experimentation with commercial field testing on livestock farms owned by a number of development organizations and influential farmers in different edapho-climatic regions. In this way, pilot units for demonstration, economic analysis and convincing of decision makers are created and …
Economics Of Producing Corn (Maize) And Sorghum As Feeds For Animal Production In China, Bingxing Zhang
Economics Of Producing Corn (Maize) And Sorghum As Feeds For Animal Production In China, Bingxing Zhang
IGC Proceedings (1977-2023)
Due to insufficient production of animal products the Chinese people have eaten too much grain and too little meat and milk. Now, as a result of burriper harvests for several years in succession, it is time for the Chinese peasants to convert their surplus grain into feeds for the development of animal production to meet the growing needs of the Chinese people for meat and milk on the one hand and for wool and leather on the other. At the same time more forage sorghum and corn should be grown, especially on unused or misused poor lands and wide hillsides …
