Duodenogastric Reflux in Health and Disease: Insights from a Computational Fluid Dynamics Model of the Stomach.

The stomach is responsible for physically and chemically processing the ingested meal before controlled emptying into the duodenum through the pyloric sphincter. An incompetent pylorus allows reflux from the duodenum back into the stomach, and if the amount of reflux is large enough, it could alter the low pH environment of the stomach and erode the mucosal lining of the lumen. In some cases, the regurgitated contents can also reach the esophagus leading to additional complications.

Paradoxical control of multifocal mammary oncogenesis by radiation therapy.

In an immunocompetent mouse model of multifocal, metachronous HR mammary carcinogenesis, we have recently demonstrated that a superior control of primary neoplastic lesions by focal radiotherapy does not necessarily translate into improved oncosuppression at non-irradiated (pre)malignant tissues. These data point to a link between local tumor control by radiotherapy and systemic oncogenesis that remains to be fully understood.

Near-universal prevalence of central adiposity in heart failure with preserved ejection fraction: the PARAGON-HF trial.

Background And Aims: An expansion of fat mass is an integral feature of patients with heart failure and preserved ejection fraction (HFpEF). While body mass index (BMI) is the most common anthropometric measure, a measure of central adiposity-the waist-to-height ratio (WHtR)-focuses on body fat content and distribution; is not distorted by bone or muscle mass, sex, or ethnicity; and may be particularly relevant in HFpEF.

Methods: The PARAGON-HF trial randomized 4796 patients with heart failure and ejection fraction ≥45% to valsartan or sacubitril/valsartan.

Using pretrained graph neural networks with token mixers as geometric featurizers for conformational dynamics.

Identifying informative low-dimensional features that characterize dynamics in molecular simulations remains a challenge, often requiring extensive manual tuning and system-specific knowledge. Here, we introduce geom2vec, in which pretrained graph neural networks (GNNs) are used as universal geometric featurizers. By pretraining equivariant GNNs on a large dataset of molecular conformations with a self-supervised denoising objective, we obtain transferable structural representations that are useful for learning conformational dynamics without further fine-tuning.

Decoherence and vibrational energy relaxation of the electronically excited PtPOP complex in solution.

Understanding the ultrafast vibrational relaxation following photoexcitation of molecules in a condensed phase is essential to predict the outcome and improve the efficiency of photoinduced molecular processes. Here, the vibrational decoherence and energy relaxation of a binuclear complex, [Pt2(P2O5H2)4]4- (PtPOP), upon electronic excitation in liquid water and acetonitrile are investigated through direct adiabatic dynamics simulations. A quantum mechanics/molecular mechanics (QM/MM) scheme is used where the excited state of the complex is modeled with orbital-optimized density functional calculations while solvent molecules are described using potential energy functions.

Interstellar spectroscopic detection of HC(S)NC and DC(S)NC.

The detection of HC(S)CN in TMC-1 suggests that HC(S)NC may also exist. To aid in its possible detection, HC(S)NC and its deuterated isotopologue DC(S)NC were investigated via high-level ab initio methods, specifically CCSD(T) and CCSD(T)-F12. By utilizing multidimensional potential energy surfaces derived from explicitly correlated coupled-cluster calculations, we analyzed their geometrical parameters, vibrational frequencies, rotational constants, and a comprehensive set of spectroscopic constants generated via the vibrational second-order perturbation theory, vibrational self-consistent field, and vibrational configuration interaction theory(VCI) approaches.

Mitigating PM Induced Myocardial Metal Deposition Through Sodium Thiosulfate Resulted in Reduction of Cardiotoxicity and Physiological Recovery From Ischemia-Reperfusion via Mitochondrial Preservation.

The cardiovascular risks linked to PM include calcification in both vasculature and myocardial tissues, leading to structural changes and functional decline. Through the selection of a clinically proven endogenous agent, sodium thiosulfate (STS), capable of addressing PM related cardiac abnormalities, we not only address the absence of effective solutions to mitigate PM toxicity, but also provide evidence for the repurposing potential of STS in ameliorating PM induced cardiac damage. Female Wistar rats were exposed to PM (250 μg/m) for 3 h daily for 21 days.

Wave-CAIPI Multiparameter MR Imaging in Neurology.

In clinical practice, particularly in neurology assessments, imaging multiparametric MR images with a single-sequence scan is often limited by either insufficient imaging contrast or the constraints of accelerated imaging techniques. A novel single scan 3D imaging method, incorporating Wave-CAIPI and MULTIPLEX technologies and named WAMP, has been developed for rapid and comprehensive parametric imaging in clinical diagnostic applications. Featuring a hybrid design that includes wave encoding, the CAIPIRINHA sampling pattern, dual time of repetition (TR), dual flip angle (FA), multiecho, and optional flow modulation, the WAMP method captures information on RF B1t fields, proton density (PD), T1, susceptibility, and blood flow.
