17β-oestradiol (E2) inhibits overeating and promotes brown adipose tissue (BAT) thermogenesis, whereas prolactin (PRL) does the opposite. During lactation, the simultaneous decline in E2 and surge in PRL contribute to maternal metabolic adaptations, including hyperphagia and suppressed BAT thermogenesis. However, the underlying neuroendocrine mechanisms remain unclear. Here, we find that oestrogen receptor alpha (ERα)-expressing neurons in the medial basal hypothalamus (MBH), specifically the arcuate nucleus of the hypothalamus and the ventrolateral subdivision of the ventromedial hypothalamus (vlVMH), are suppressed during lactation. Deletion of ERα from MBH neurons in virgin female mice induces metabolic phenotypes characteristic of lactation, including hyperprolactinemia, hyperphagia …

Anthropogenic Influences On Parasitoid Wasps’ Biocontrol Of Invasive Insect Pest Species In Africa, Fathiya M. Khamis, Inusa J. Ajene

All Peer-Reviewed Publications

Sustainable agriculture is crucial to ensuring food and nutritional security and improving livelihoods of millions across Africa. However, agricultural production is constrained by native and invasive pests. Indiscriminate insecticide use is often the first line of action to manage these pests, harming human and animal health, and impacting biodiversity. Thus, shifting to more ecologically sustainable alternatives is key to biodiversity conservation and sustainable agriculture. Biological control is a core component of integrated pest management strategies, and natural enemies, like parasitoid wasps, are considered one of the most environmentally sustainable means of managing pests. However, the Anthropocene plays a significant role …

Nanosilica Supplementation In Tomato Increases Oviposition On Stems And Caterpillar Mortality In The Tomato Pinworm, Kokou R. Fiaboe, Fathiya M. Khamis, Xavier Cheseto, Abdullahi A. Yusuf, Baldwyn Torto

All Peer-Reviewed Publications

Silicon-induced responses play a key role in plant defense against herbivory, though the underlying mechanisms remain underexplored. In this study, we examined how mesoporous silica nanoparticles (MSNs) affect tomato (Solanum lycopersicum) defense against an invasive and highly destructive lepidopteran herbivore, the tomato pinworm (TPW), Phthorimaea absoluta. In tomato plants supplemented with MSN, prior exposure to TPW oviposition shifted subsequent egg-laying from a preference for leaves to an even distribution between stems and leaves. This shift was not observed in nonsilicon-supplemented plants. Prolonged oviposition triggered pigmentation in the basal cells of type I glandular trichomes on the stems of silicon-supplemented plants. …

Metabolic imaging produces powerful visual assessments of organ function in vivo. Current techniques can be improved by safely increasing metabolic contrast. The gold standard, 2-[18F]fluorodeoxyglucose-positron emission tomography (FDG-PET) imaging, is limited by radioactive exposure and sparse assessment of metabolism beyond glucose uptake and retention. Deuterium magnetic resonance imaging (DMRI) with [6,6-2H2]glucose is nonradioactive, achieves tumor metabolic contrast, but can be improved by enriched contrast from deuterated water (HDO) based imaging. Here, we developed a DMRI protocol employing [2H7]glucose.

The Mechanistic Target Of Rapamycin Mediates Clostridium Perfringens-Induced Chicken Necrotic Enteritis Attenuated By Secondary Bile Acid Deoxycholic Acid, Mohit Bansal, Tahrir Alenezi, Ying Fu, Janashrit Shrestha, Ayidh Almansour, Hong Wang, Anamika Gupta, Rohana Liyanage, Xiaolun Sun

Poultry Science Faculty Publications and Presentations

Clostridium perfringens is a prevalent gut bacterial pathogen in humans and animals. This study investigated the role of the mechanistic targets of rapamycin (mTOR) and deoxycholic acid (DCA) on C. perfringens intestinal infection. Chickens were sequentially infected with Eimeria maxima and received the mTOR inhibitor rapamycin and DCA. C. perfringens-induced necrotic enteritis (NE) was evaluated using body weight gain (BWG), histopathology, bile acids, pathogen colonization, cell infiltration and death, and gene expression. The significant difference of p < 0.05 was analyzed by one-way ANOVA and multiple comparisons. Notably, rapamycin strongly reduced the subclinical and clinical NE histopathologies. DCA and DCA combined with rapamycin alleviated clinical NE and BWG loss. Rapamycin, DCA, and DCA + rapamycin attenuated bile acid reduction in NE birds, and they also reduced immune cell infiltration into the intestinal lamina propria as well as immune cell migration in vitro. At molecular levels, DCA and DCA + rapamycin reduced proinflammatory IFN gamma, MMP9, IL23, and IL17 gene expression. Rapamycin, DCA, and DCA + rapamycin reduced NE-induced intestinal cell apoptosis. Together, these results suggest that mTOR signaling mediates C. perfringens-induced ileitis, and combining mTOR inhibition and DCA improves the intervention efficacy against NE ileitis and BWG loss.

Contrasting Effects Of Climate Warming On Hosts And Parasitoids: Insights From Rocky Mountain Aspen Leaf Miners And Their Parasitoids, Alisha A. Shah, Emily Hamant, Juan G. Rubalcaba, Beau Larkin, Andrew A. Forbes, H. Arthur Woods

Aspen Bibliography

Because temperature has pervasive effects on biological rates, climate warming may alter the outcomes of interactions between insect hosts and their parasitoids, which, for many host species, constitute the single largest source of mortality. Despite growing interest in parasitoid-host responses due to climate change, there are few empirical tests of thermal tolerance differences between non-model lepidopteran hosts and their parasitoids and almost none from mountain ecosystems where warming is occurring more rapidly. We examined the thermal ecology of a host–parasitoid interaction in the Rocky Mountains using the wild populations of the aspen leaf miner (Phyllocnistis populiella) and a …

Murine Studies On Ketogenic Modulation Of Metabolism And Epigenetics In Olfaction- Based Learning, Lps Inflammatory Response, And Sex Dimorphisms In Dietary Response, Sara E. H. Moss

USF Tampa Graduate Theses and Dissertations

Ketogenic diets are well-established therapeutic interventions for epilepsy, with documented neuroprotective effects arising from their metabolic, antioxidant and anti-inflammatory properties. Beyond epilepsy, ketogenic therapies are under investigation for various conditions including Alzheimer disease, cancer, diabetes, and cardiovascular disease. These diets suppress insulin levels and shift metabolic physiology toward fat and ketone body metabolism. This elevates circulating levels of ketone bodies, namely beta-hydroxybutyrate, acetoacetate, and acetone, which serve as both energy substrates and signaling molecules. The state of elevated ketone bodies (ketosis) can be achieved with various formulations of a ketogenic diet as well as exogenous ketone supplementation, though the signaling …
