Multi‐Target Pharmacological Mechanisms of Salvia miltiorrhiza Bunge in Metabolic Syndrome and Cardiovascular Diseases: A Comprehensive Review Based on the Theory of “Same Treatment for Different Diseases”

open access: yesPhytotherapy Research, EarlyView.
Salvia miltiorrhiza Bunge in metabolic syndrome and cardiovascular diseases: multi‐target actions on shared signaling pathways. ABSTRACT Metabolic syndrome (MetS) represents a clinical disorder characterized by the clustering of conditions including obesity, elevated blood sugar levels, and high lipid levels, which are intricately linked to the onset ...

Membrane-bound light-activated proteins: Study of the visual pigments and bacteriorhodopsin analogues

open access: yes, 2006
The photophysical properties of the retinal-binding proteins, rhodopsin, bacteriorhodopsin and selected cone pigments are analyzed by using spectroscopy, chromophore analogues and site-directed mutagenesis.

Beyond spectral tuning: human cone visual pigments adopt different transient conformations for chromophore regeneration

open access: yes, 2016
The final publication is available at Springer via http://dx.doi.org/10.1007/s00018-015-2043-7Human red and green visual pigments are seven transmembrane receptors of cone photoreceptor cells of the retina that mediate color vision.

Advances in deep‐tissue fluorescence imaging through optical clearing: A review

open access: yesVIEW, EarlyView.
Optical clearing refers to techniques that are used to improve the optical transparency of biological tissues. Optical clearing enables imaging of deeper lying tissues as well as 3D volumetric imaging of whole organs. This review examines reports on the integration of optical clearing with advanced fluorescence imaging techniques, with particular ...

Gut microbiota dysbiosis in the inflammatory pathogenesis of diabetic retinopathy

open access: yesVIEW, EarlyView.
This graphical abstract illustrates how gut dysbiosis drives diabetic retinopathy through the gut‐retina axis, a process unfolding in three interconnected stages. First, in the gut, a decrease in beneficial bacteria and an increase in pro‐inflammatory taxa compromise the intestinal barrier, causing a “leaky gut” that allows LPS to translocate into the ...

HSPE1 deficiency underlies the crosstalk between metabolic dysfunction‐associated steatotic liver disease and age‐related macular degeneration

open access: yesVIEW, EarlyView.
Rare‐earth ions act as multifunctional modifiers in perovskite solar cells by improving charge transport, suppressing oxygen vacancies, passivating defects, promoting grain growth, and enabling redox‐mediated stabilization. In addition, RE‐doped layers can expand spectral utilization through upconversion and downconversion, thereby enhancing light ...

Evolution of visual and non-visual pigments

open access: yes, 2014
Photopigments are molecules that react to light and mediate a number of processes and behaviours in animals. Visual pigments housed within the photoreceptors of the eye, such as the rods and cones in vertebrates are the best known, however, visual ...

Gastritis and age‐related macular degeneration: Potential roles of metabolomic dysregulation and photoreceptor alterations

open access: yesVIEW, EarlyView.
Abstract Age‐related macular degeneration (AMD) is a degenerative retinal disorder and a leading cause of global visual impairment, yet effective treatments remain limited. While gastritis is a prevalent clinical condition among older populations and has been associated with adverse effects on the central nervous system, its potential association with ...
