Excess lipid droplet (LD) accumulation is implicated in various diseases, including Alzheimer's disease (AD), yet the mechanisms underlying this accumulation remain unclear. Apolipoprotein E (ApoE) is a droplet-associated protein, and its E4 variant confers the greatest genetic risk for late-onset AD while also being linked to increased neuroinflammation and LD accumulation. In this study, we compared the lipid and protein composition of hepatic LDs in targeted replacement mice expressing human E3 (neutral) or E4 (risk variant), under both baseline conditions and following lipopolysaccharide (LPS) administration. Lipidomic analysis revealed that E4 LDs exhibit a shift in glycerophospholipid distribution, with an increase …

Physiology Faculty Publications

Transferrin receptor 1 (TfR1), a crucial cellular iron receptor, has a variety of biological functions. We have previously reported that TfR1 abundance increases in the aortic media of hypertensive rat models. However, its role in vascular diseases remains unknown. In the present study, we generated smooth muscle cell (SMC)-specific TfR1 deficient mice and examined the impact of its deletion in mouse models of hypertension induced by angiotensin II or deoxycorticosterone acetate/salt administration. SMC-specific TfR1 deletion attenuated medial thickening and elastin fragmentation in both mouse models of hypertension. These results indicate that TfR1 in SMCs exerts a role in vascular remodeling …

Lignans are small polyphenolic compounds that play an active role in plant defense against pathogens and predators. Recently, lignan machilin D was reported to be effective as an anti-tumorigenic agent in triple negative breast cancer (TNBC) tumor-bearing mice. Previous studies have relied on plant-extracted material limiting scalability and diversification of the natural scaffold. Herein, we describe a generalizable one-pot synthesis of machilin D and its derivatives via an iron chloride-induced dimerization of isoeugenol. Employing this synthetic methodology allowed for a robust diversification campaign to access seven (7) new lignan derivatives of the machilin D family with superior anti-proliferative properties in …

Surgery Faculty Publications

Thoracic aortopathies are life-threatening diseases including aneurysm, dissection, and rupture. Cilostazol, a phosphodiesterase (PDE) 3 inhibitor, and sildenafil, a PDE5 inhibitor, have been used clinically for peripheral arterial disease and erectile dysfunction or pulmonary hypertension, respectively. Recent studies report their effects on abdominal aortic aneurysm formation. However, their impacts on thoracic aortopathy remain unknown. In this study, we investigated whether cilostazol and sildenafil affect thoracic aortopathy induced by β-aminopropionitrile (BAPN) administration in mice. Bulk RNA sequencing analysis revealed that BAPN administration upregulated Pde3a transcription in the ascending aorta and Pde5a in both ascending and descending regions before thoracic aortopathy formation. …

Effect Of Lactic Acid Bacteria On Silage Fermentation, Ph Hellings, G Bertin, M Vanbelle Jul 2025

Effect Of Lactic Acid Bacteria On Silage Fermentation, Ph Hellings, G Bertin, M Vanbelle

IGC Proceedings (1977-2023)

Inoculants were tested to determine their suitability for use as silage aids. Studies carried out in laboratory indicated (1) that the minimum inoculum should be at least 105 viable organisms per gram of fresh fodder and (2) of all bacterial strains tested, only the Lactobacillus and, specifically, L. casei improved storage characteristics. But the efficiency of an inoculant was subordinated to the fermentable sugars content of the crops. In this respect, alfalfa and second cut grass had the lowest potential for ensilage. Energy was supplied as a mixture of milled barley and amylolytic complex. The influence of a 1: 1: …

High Value Productions From Lucerne: A New Zealand Perspective, R M. Mcdonald, P E. Donnelly, R A. Mills, S R. Vaughan

IGC Proceedings (1977-2023)

Research at Ruakura has aimed at improving the economics of lucerne protein extraction, by extracting more of the protein (up to 85%) and by searching for ways to get maximum value for each of the components in the lucerne. Presently most lucerne protein concentrate is sold on the basis of its protein and xanthophyll contents, which are valued by poultry growers. Other components, including carotene, chlorophyll and vitamin E, are not valued in poultry feed and consequently could be extracted and sold separately. Carotene and vitamin E have recently been associated with cancer prevention. The paper also discusses the value …

The Effect Of The Harvest Time, Height And Length Of Cutting On The Quality And Nutrient Yield Of Japanese Millet Silage, T Nakui, N Yahara, S Takai

IGC Proceedings (1977-2023)

The experiments were made to determine the appropriate harvest time, height and length of cutting of Japanese millet for silage. Harvesting the millet at the end of the late dough stage was found to be the most favorable for silage, and the fermenting quality of the silage was improved by higher cutting and keeping the length of the cutting short ( < 10 mm). Dry weight yield of the plant (x) well correlated with TDN yield (Y) of the silage (r = 0.91, Y = 0.511x - 64.7). A negative correlation was obtained between the rate of temperature rise during the second fermentation process of silage broken the seal and the content of butyric acid in the silage. The second fermentation was suppressed when the butyric acid content in the total acid of the silage was more than 3 % .

Losses During Ensiling Due To Gas Exchange, H Honig, E Zimmer Jul 2025

Losses During Ensiling Due To Gas Exchange, H Honig, E Zimmer

IGC Proceedings (1977-2023)

Gas exchange leading to air infusion into the silo during the storage period is one of the main reasons for poor silage quality and additional losses. To make these losses better predictable, and to show ways to ensiling technology to avoid them, the parameters influencing the gas exchange in silage stacks have to be defined and quantified. The motive powers for this gas exchange are "breathing" in gastight systems, and CO2 flow off in "open" systems. Recent experiments using 6 m3 pilot silos to evaluate and quantify these losses, especially those due to CO2 flow off, show the following results: …
