Increased accuracy of ligand sensing by receptor diffusion on cell surface [PDF]
Physical Review E 82, 041902 (2010), 2010 The physical limit with which a cell senses external ligand concentration corresponds to the perfect absorber, where all ligand particles are absorbed and overcounting of same ligand particles does not occur. Here we analyze how the lateral diffusion of receptors on the cell membrane affects the accuracy of sensing ligand concentration.

Deep learning-based holographic polarization microscopy [PDF]
ACS Photonics (2020), 2020 Polarized light microscopy provides high contrast to birefringent specimen and is widely used as a diagnostic tool in pathology. However, polarization microscopy systems typically operate by analyzing images collected from two or more light paths in different states of polarization, which lead to relatively complex optical designs, high system costs or

Energy metabolism and glutamate-glutamine cycle in the brain: a stoichiometric modeling perspective [PDF]
BMC Systems Biology 7:103 (2013), 2013 The energetics of cerebral activity critically relies on the functional and metabolic interactions between neurons and astrocytes. Important open questions include the relation between neuronal versus astrocytic energy demand, glucose uptake and intercellular lactate transfer, as well as their dependence on the level of activity.

Exercise and Vitamin D Supplementation Modify Spleen Morphology in Lean, but not, in Monosodium-Glutamate-Obese Rats [PDF]
Journal of Spleen and Liver Research, 2019 We evaluated the effect of exercise and vitamin D supplementation on histological aspects of the spleens of lean and obese rats. Male Wistar rats received neonatal administration of monosodium glutamate (MSG; 4g/Kg), while Control (CON) rats received an equimolar solution.

Advanced Energy and Sustainability Research, EarlyView.The decomposition of single‐use plastics by selected insects is often sustained or enhanced through the addition of natural supplements or feeds. Herein, the rationale behind these choices is demonstrated by examining the effects of selected amino acids and water as enhancers in the biodegradation of polystyrene by mealworms.

International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background According to the National Health and Nutrition Examination Survey (NHANES), more than 20 million Americans suffer from chronic taste problems. Unfortunately, quantitative testing is rarely performed, self‐reports are inaccurate, and “taste” is often confused with olfaction‐dependent flavors.

Probing Scalar Coupling Differences via Long-Lived Singlet States [PDF]
, 2015 We probe small scalar coupling differences via the coherent interactions between two nuclear spin singlet states in organic molecules. We show that the spin-lock induced crossing (SLIC) technique enables the coherent transfer of singlet order between one spin pair and another.

In Vivo Magnetic Resonance Spectroscopy by J-Locked Chemical Shift Encoding for Determination of Neurochemical Concentration and Transverse Relaxation Time [PDF]
arXiv, 2023 Cell pathology in neuropsychiatric disorders has mainly been accessible by analyzing postmortem tissue samples. Although molecular transverse relaxation informs local cellular microenvironment via molecule-environment interactions, precise determination of the transverse relaxation times of molecules with scalar couplings (J), such as glutamate and ...
