Microglia are the major cell type expressing complement C3a receptor (C3aR) in the brain. Using a knockin mouse line in which a Td-tomato reporter is incorporated into the endogenous C3ar1 locus, we identified 2 major subpopulations of microglia with differential C3aR expression. Expressing the Td-tomato reporter on the APPNL-G-F-knockin (APP-KI) background revealed a significant shift of microglia to a high-C3aR-expressing subpopulation and they were enriched around amyloid β (Aβ) plaques. Transcriptomic analysis of C3aR-positive microglia documented dysfunctional metabolic signatures, including upregulation of hypoxia-inducible factor 1 (HIF-1) signaling and abnormal lipid metabolism in APP-KI mice compared with wild-type controls. Using primary …

Alterations caused by Trypanosoma cruzi in the composition of gut microbiome may play a vital role in the host-parasite interactions that shapes physiology and immune responses against infection. Thus, a better understanding of this parasite-host-microbiome interaction may yield relevant information in the comprehension of the pathophysiology of the disease and the development of new prophylactic and therapeutic alternatives. Therefore, we implemented a murine model with two mice strains (BALB/c and C57BL/6) to evaluate the impact of Trypanosoma cruzi (Tulahuen strain) infection on the gut microbiome utilizing cytokine profiling and shotgun metagenomics. Higher parasite burdens were observed in cardiac and intestinal …

Severe traumatic injury leads to marked systemic inflammation and multiorgan injury. Endogenous drivers such as extracellular nucleic acid may play a role in mediating innate immune response and the downstream pathogenesis. Here, we explored the role of plasma extracellular RNA (exRNA) and its sensing mechanism in inflammation and organ injury in a murine model of polytrauma. We found that severe polytrauma—bone fracture, muscle crush injury, and bowel ischemia—induced a marked increase in plasma exRNA, systemic inflammation, and multiorgan injury in mice. Plasma RNA profiling with RNA sequencing in mice and humans revealed a dominant presence of miRNAs and marked differential …

Ras plays an essential role in the development of acinar-to-ductal metaplasia (ADM) and pancreatic ductal adenocarcinoma (PDAC). However, mutant Kras is an inefficient driver for PDAC development. The mechanisms of the switching from low Ras activity to high Ras activity that are required for development and progression of pancreatic intraepithelial neoplasias (PanINs) are unclear. In this study, we found that hematopoietic progenitor kinase 1 (HPK1) was upregulated during pancreatic injury and ADM. HPK1 interacted with the SH3 domain and phosphorylated Ras GTPase-activating protein (RasGAP) and upregulated RasGAP activity. Using transgenic mouse models of HPK1 or M46, a kinase-dead mutant of …

Early phase diabetes is often accompanied by pain sensitization. In Drosophila, the insulin receptor (InR) regulates the persistence of injury-induced thermal nociceptive sensitization. Whether Drosophila InR also regulates the persistence of mechanical nociceptive sensitization remains unclear. Mice with a sensory neuron deletion of the insulin receptor (Insr) show normal nociceptive baselines; however, it is uncertain whether deletion of Insr in nociceptive sensory neurons leads to persistent nociceptive hypersensitivity. In this study, we used fly and mouse nociceptive sensitization models to address these questions. In flies, InR mutants and larvae with sensory neuron-specific expression of RNAi transgenes targeting InR exhibited persistent …

Escherichia coli is a leading cause of invasive bacterial infections in humans. Capsule polysaccharide has an important role in bacterial pathogenesis, and the K1 capsule has been firmly established as one of the most potent capsule types in E. coli through its association with severe infections. However, little is known about its distribution, evolution and functions across the E. coli phylogeny, which is fundamental to elucidating its role in the expansion of successful lineages. Using systematic surveys of invasive E. coli isolates, we show that the K1-cps locus is present in a quarter of bloodstream infection isolates and has emerged …

Tbet+CD11c+ B cells, also known as age-associated B cells (ABCs), are pivotal contributors to humoral immunity following infection and in autoimmunity, yet their in vivo generation is incompletely understood. We used a mouse model of systemic acute lymphocytic choriomeningitis virus infection to examine the developmental requirements of ABCs that emerged in the spleen and liver. IL-21 signaling through STAT3 was indispensable for ABC development. In contrast, IFN-γ signaling through STAT1 was required for B cell activation and proliferation. Mice that underwent splenectomy or were deficient in lymphotoxin α generated hepatic ABCs despite the lack of secondary lymphoid organ contributions, suggesting …

Prostate cancer is the most common cancer among men and the second leading cause of cancer-related deaths in men in the United States. The treatment paradigm for prostate cancer has evolved with the emergence of a variety of novel therapies which have improved survival; however, treatment-related toxicities are abundant and durable responses remain rare. Immune checkpoint inhibitors have shown modest activity in a small subset of patients with prostate cancer and have not had an impact on most men with advanced disease. The discovery of prostate-specific membrane antigen (PSMA) and the understanding of its specificity to prostate cancer has identified …

Woman Becoming… Gender Possibilities In Selected Speculative Short Stories Of Intan Paramaditha And Isabel Yap, Grace V.S. Chin Jun 2023

Woman Becoming… Gender Possibilities In Selected Speculative Short Stories Of Intan Paramaditha And Isabel Yap, Grace V.S. Chin

Wacana, Journal of the Humanities of Indonesia

The ontological question of woman’s nature forms the focus of this essay, which develops the theory of “woman-becoming…” to examine how the hegemonic patriarchal discourses and constructs of woman and femininity are subverted and reinterpreted in two speculative short stories by transnational Southeast Asian women writers, namely Intan Paramaditha’s “Beauty and the Seventh Dwarf” (2018) and Isabel Yap’s “Good Girls” (2021). Of interest here are the gender possibilities of the female characters, which uphold women’s freedom, agency, thinking, feeling, creation, narration and expression in the making of herstory—indeed, everywoman’s potential for change and transformation, and to become more than what …

Parents Of Students On The Autism Spectrum Call For Social And Academic Inclusive Practices, Stephanie C. Holmes Jun 2023

Parents Of Students On The Autism Spectrum Call For Social And Academic Inclusive Practices, Stephanie C. Holmes

Tapestry: Journal of Research in Education

Inclusive education practices must incorporate both social and academic inclusion. Before 1975, students with various disabilities did not have the same access to public education as their nondisabled or neuro-typically developing peers. With the passing of the Education for All Handicapped Children Act, it was mandated that all schools that receive federal funds must provide equal access to education as a right to students with any physical, behavioral, or mental handicaps. While the mandates have broadened throughout the years, merely having a diagnosis of Autism does not guarantee resources or supports to the student unless there are also academic concerns. …

Relative Yields And Nutritive Value Of Whole Crop Rice Harvested On Four Successive Dates For Forage In Korea, Jong-Geun Kim, Y. C. Lim, E. S. Chung, S. H. Yoon, S. Seo, M. J. Kim

IGC Proceedings (1977-2023)

About four million tons of forages are fed to ruminants in Korea, but half of them rely on rice straw as roughage and 0.6 million tons of forage was imported. The lack of forage results in increased imports of concentrate feeds and increased production cost. Now, Korea has about 1.1 million ha of rice fields, but as a consequence of world trade negotiation, Korea will open the rice market from next year. It is expected that due to aging farmers and lower rice price, about 0.2 million ha of paddy field will not be cultivated for grain rice. Therefore, we …

IGC Proceedings (1977-2023)

In Uganda, peri-urban agriculture is very important in sustaining livelihoods of the increasing population in urban and peri-urban (U & PU) areas. However, this form of agriculture has a number of problems, feed shortage being the most important. The agricultural produce brought in from the rural areas is marketed in raw form hence increasing the crop wastes in the market areas. The crop wastes, if properly sorted, can serve as alternative feeds for the animals kept in the U & PU areas. Banana (Musa spp) peelings (BP) constitute the largest proportion of all the crop wastes in most …

Changes In Grass Quality Of Coastal Meadows In Estonia, Tiina Köster, Karin Kauer, R. Viiralt, A. Selge Jun 2023

Changes In Grass Quality Of Coastal Meadows In Estonia, Tiina Köster, Karin Kauer, R. Viiralt, A. Selge

IGC Proceedings (1977-2023)

In Estonia the reason for reduction in coastal meadows and expansion of the stands of the common reed (Phragmites australis) is the discontinuation of traditional use of grasslands which were previously grazed and cut. Phragmites australis usually produces dense and monospecific stands at the waterline, where species richness is low. It can survive in ungrazed shore meadows, but it suffers from grazing (Tyler, 1969). The investigated Phragmitetum australis association had been influenced by grazing activities, but it remained rather sparse and due to that had relatively low productivity, reaching 3.11 t DM/ha. Traditionally coastal meadows have been used …

Accumulation Of Zearalenone In Herbage Of Winter Pasture Situated In West Poland, P. Goliński, M. Kostecki, Barbara Golińska, B. T. Golińska, P. K. Goliński

IGC Proceedings (1977-2023)

The importance of winter pastures in beef production in Europe has been growing steadily. In Poland, especially in its western part, there are already farms which utilise pasture swards during late autumn and winter. The major problem, however, is the quality of forage ingested by animals as it tends to deteriorate with the passage of the vegetation season with danger of accumulation of various mycotoxins (Laser et al., 2003) of which the most important is zearalenone (ZEA).

Diversity And Variation In Nutritive Value Of Plants Growing On 2 Saline Sites In Southwestern Australia, Hayley C. Norman, R. A. Dynes, D. G. Masters Jun 2023

Diversity And Variation In Nutritive Value Of Plants Growing On 2 Saline Sites In Southwestern Australia, Hayley C. Norman, R. A. Dynes, D. G. Masters

IGC Proceedings (1977-2023)

In south-western Australia 10% or 1.8 million ha of the farmed area is affected by dryland salinity and a further 6 million ha are at risk of salinity (NLWRA, 2001). Animal production from saltbush (Atriplex spp.)-based pasture systems represents the most likely large-scale opportunity for productive use of saline land in the short to medium term. Feeding saltbush-based pastures as a maintenance feed during the prolonged autumn feed gap typical in Mediterranean-type climates maximises their economic value. The aim of this study was to explore the diversity and nutritive value of plants that typically persist in saltbush-based saltland pastures.

Forage Composition And Quality Of Tankbed Grassland Ecosystems In Sri Lanka; A Preliminary Study Of “Tabbowa” Tank, G. G. C. Premalal, Sujatha Premaratne

IGC Proceedings (1977-2023)

Although, Sri Lanka does not have large natural lakes, the early settlers devoted their energy to build water bodies (tanks or reservoirs) in association with forest catchments to provide water for irrigation. The tank bed is a grassland area of the tank, which lies between the catchment forest and the present water level. In general, the tankbed has three major zones - lower, middle and upper - and in some seasons the middle and upper parts may be underwater. This tankbed area is dominated by grassland vegetation and is a valuable feeding ground for free-grazing livestock. The main objective of …

Variations In Nutritive Values Of Two Different Desert Forage Plants Growing In The United Arab Emirate Environment, T. Ksiksi, A. Bamakhrama, M. Satri Jun 2023

Variations In Nutritive Values Of Two Different Desert Forage Plants Growing In The United Arab Emirate Environment, T. Ksiksi, A. Bamakhrama, M. Satri

IGC Proceedings (1977-2023)

Forage plants in desert environments have to withstand both shortages in resources and over grazing during most years. This variation in resource availability is associated with variation in the nutritive values of the plant species. Moreover, these differences are not only seasonal but also vary between plant parts. Variations in nutritive values in key species, therefore, need to be better understood in order to sustainably feed livestock (Abdurazak et al., 2000), because effective management requires adequate knowledge of the interaction between the animal, the pasture and the environment (Kassilly, 2002). Forage toxicity could, however, cause irreparable damage to production. …

IGC Proceedings (1977-2023)

Silvopastoralism is a sustainable way of land management that reduces fire risk due to the reduction of fuel under trees when plants are used as animal food. This is particularly important in areas like Galicia that have 16% of the fired area of Europe. Silvopastoral systems can contribute to environment conservation and provide feed for autochthonous breeds more adapted to mountain conditions, enhancing biodiversity conservation. In formation on seasonal changes in crude protein content of spontaneous species will indicate better management of pasture resources in mountain areas.
