We used (1)H nuclear magnetic resonance spectroscopy to describe key metabolites of the polar metabolome of the freshwater mussel, Elliptio complanata. Principal components analysis documented variability across tissue types and river of origin in mussels collected from two rivers in North Carolina (USA). Muscle, digestive gland, mantle and gill tissues yielded identifiable but overlapping metabolic profiles. Variation in digestive gland metabolic profiles between the two mussel collection sites was characterized by differences in mono- and disaccharides. Variation in mantle tissue metabolomes appeared to be associated with sex. Nuclear magnetic resonance spectroscopy is a sensitive means to detect metabolites in the tissues of E. complanata and holds promise as a tool for the investigation of freshwater mussel health and physiology.

Multimodal assessment predicts cognitive impairment after aneurysmal subarachnoid hemorrhage: a prospective cohort study.
Int J Surg
January 2025
Department of neurosurgery, Xuanwu Hospital, Capital Medical University, Beijing, China.
Background: Risk factors and mechanisms of cognitive impairment (CI) after aneurysmal subarachnoid hemorrhage (aSAH) are unclear. This study used a neuropsychological battery, MRI, ERP and CSF and plasma biomarkers to predict long-term cognitive impairment after aSAH.
Materials And Methods: 214 patients hospitalized with aSAH (n = 125) or unruptured intracranial aneurysms (UIA) (n = 89) were included in this prospective cohort study.
Preparation of pH-Responsive Oil-in-Water Microemulsion Using a Full-Bio-Based Surfactant Containing a Dynamic Covalent Bond.

College of Bioresources Chemical and Materials Engineering, Shaanxi University of Science and Technology, Xi'an 710021, China.
A novel pH-responsive full-bio-based surfactant (Ca-S) containing a dynamic covalent bond is synthesized using renewable cashew phenol, 5-chloro-2-furanaldehyde, and taurine. The structure of Ca-S is characterized by Fourier transform infrared spectroscopy (FTIR) and H nuclear magnetic resonance (NMR) analysis. Limonene containing oil-in-water (O/W) microemulsions are prepared on the basis of the Ca-S surfactant and are applied to the remediation of oil-contaminated soil under low-energy conditions at ambient temperature.

Applied Nuclear Technology in Geosciences Key Laboratory of Sichuan Province, Chengdu University of Technology, Chengdu, People's Republic of China.
Context: The study of the influence of solvent on 1-bromo adamantane (BAD) exposes prominent solvatochromatic shifts in the optical absorbance and substantial solvent effects on the electronic structure. This facilitates the molecular probe abilities for the BAD with respect to the surrounding environments such as dielectric constant and polarity. BAD exhibits positive solvatochromism for nonpolar solvents and negative solvatochromatic shifts for polar and aromatic solvents.

The brain entropy (BEN) reflects the randomness of brain activity and is inversely related to its temporal coherence. In recent years, BEN has been found to be associated with a number of neurocognitive, biological, and sociodemographic variables such as fluid intelligence, age, sex, and education. However, evidence regarding the potential relationship between BEN and brain structure is still lacking.

With the aging of the general population and the rise in surgical and transcatheter aortic valve replacement, there will be an increase in the prevalence of prosthetic aortic valves. Patients with prosthetic aortic valves can develop a wide range of unique pathologies compared to the general population. Accurate diagnosis is necessary in this population to generate a comprehensive treatment plan.
