Post-acute sequelae of COVID-19 (PASC) encompasses persistent neurological disease, including olfactory and cognitive dysfunction. The basis for this dysfunction is poorly understood. Here, we report neurological dysfunction for at least 120 d postinfection in mice infected with a virulent nonneurotropic mouse-adapted SARS-CoV-2. Long after recovery from nasal infection, we observed diminished tyrosine hydroxylase expression in olfactory bulb glomeruli and in substantia nigra. Similar changes...

Glioblastoma (GBM) is a malignancy with a complex tumour microenvironment (TME) dominated by GBM stem cells (GSCs) and infiltrated by tumour-associated macrophages (TAMs) and exhibits aberrant metabolic pathways. Lactate is a critical glycolytic metabolite that promotes tumour progression; however, the mechanisms of lactate transport and lactylation in the TME of GBM remain elusive. Here we show that lactate is transported from TAMs to GSCs via MCT4-MCT1. TAMs provide lactate to GSCs, promoting...

Upland cotton (Gossypium hirsutum), one of the world's major fiber crops, faces challenges from the genetic homogeneity of modern varieties. Here we present 107 gold-standard genome assemblies spanning the wild-to-domesticated continuum, revealing six large-scale structural variations, including a chromosomal reciprocal translocation and five inversions tracing the evolutionary history of cultivated cotton in the Americas. This history also involved continuous introgression from Gossypium...

Background: Chlorhexidine (CHX) is an effective antiseptic rinse for managing gingival inflammation; however, side effects such as staining and altered taste limit its long-term use. StellaLife^(®) (SL), an herbal-based mouth rinse and a gel, has shown promising in vitro effects, including enhanced biocompatibility and wound healing. This study aimed to compare the clinical efficacy of SL and 0.12% CHX in an experimental gingivitis model. Methods: In this randomized, controlled, cross-over...

CONCLUSIONS: This study presents a novel role for selective superoxide dismutase mimetics, such as RUC, in protecting against CTI-induced cardiovascular toxicities. As RUC dismutates superoxide, the results suggest superoxide plays a key part in the modulation of mitochondrial oxidative phosphorylation, activation of the canonical TGF-β/Smad pathway, and ionizing radiation cardiovascular side effects. These findings suggest an association between RUC treatment and TGF-β pathway antagonism that...

Recent studies suggest that prediabetes is an independent risk factor for cardiovascular thrombotic events. However, the mechanisms that may promote platelet activation and thrombosis in prediabetes remain elusive. To determine mechanisms linking prediabetes and thrombosis as a function of age, we recruited prediabetic and normoglycemic Veterans in young and middle-age groups. Compared to normoglycemic subjects, platelets from those with prediabetes exhibited increased activation,...

Objective. This review investigates the use of cone-beam computed tomography (CBCT) in conjunction with radiomics for external beam radiation therapy (EBRT) in cancer treatment. CBCT, which provides high-resolution, volumetric images, offers a promising tool for precision treatment delivery. By integrating radiomics and quantitative features extracted from CBCT, this review explores potential advancements in tumor characterization, treatment planning, and monitoring treatment responses in...

A first search for beyond the standard model physics in jet multiplicity patterns of multilepton events is presented, using a data sample corresponding to an integrated luminosity of 138 fb^{-1} of 13 TeV proton-proton collisions recorded by the CMS detector at the LHC. The search uses observed jet multiplicity distributions in one-, two-, and four-lepton events to explore possible enhancements in jet production rate in three-lepton events with and without bottom quarks. The data are found to be...

A search for the dimuon decay of the Higgs boson is presented based on pp collision data recorded by ATLAS during Run 3 of the Large Hadron Collider, corresponding to an integrated luminosity of 165 fb^{-1} at sqrt[s]=13.6 TeV. To enhance the sensitivity, the results are combined with those from Run 2. An excess of events over the background is observed with a significance of 3.4σ (2.5σ expected). The best-fit signal strength is μ=1.4±0.4. This result provides evidence for the H→μμ decay with...

CONCLUSION: In summary, amobarbital injection loaded in F127/HA hydrogel reduced cellular and structural degenerative changes against herniated discal injuries. Therefore, amobarbital has great potential for treating degenerative disc degeneration.

The benefit of rituximab maintenance after first-line (1L) bendamustine and rituximab (BR) in patients with mantle cell lymphoma (MCL) remains uncertain, with inconsistent results from the phase 2 MAINTAIN trial and several retrospective studies. We conducted a large retrospective study at 27 US and Canadian academic centers to examine the benefit of rituximab maintenance after BR. A total of 911 patients received 1L BR between 2010-2020, and 703 had an objective response and no evidence of...

CONCLUSIONS: Based on our results, sirtinol shows promise as a selective, redox-modulating therapeutic for DIPG that enhances oxidative stress and interferes with DNA repair.
