Visual pigments, ocular filters and the evolution of snake vision [PDF]

open access: yes, 2016
Much of what is known about the molecular evolution of vertebrate vision comes from studies of mammals, birds and fish. Reptiles (especially snakes) have barely been sampled in previous studies despite their exceptional diversity of retinal photoreceptor

HIF2A as a prognostic and clinical therapeutic target in ovarian clear cell carcinoma

open access: yesInternational Journal of Cancer, EarlyView.
What's New? Ovarian clear cell carcinoma is highly associated with hypoxia. Hypoxia‐inducible factor 2A (HIF2A) is a key regulator of hypoxic responses, but its role in ovarian clear cell carcinoma remains unclear. This study demonstrated the unfavorable prognostic significance of HIF2A expression in ovarian clear cell carcinoma.

Multiple Cone Visual Pigments and the Potential for Trichromatic Colour Vision in Two Species of Elasmobranch [PDF]

open access: yes, 2004
Elasmobranchs (sharks, skates and rays) are the modern descendents of the first jawed vertebrates and, as apex predators, often occupy the highest trophic levels of aquatic (predominantly marine) ecosystems.

Non‐invasive and efficient diabetic retinal mitochondrial repair nanoplatform based on engineered endothelial mitochondrial‐derived vesicles with dynamic integrated stress response modulation

open access: yesInterdisciplinary Medicine, EarlyView.
Under hyperglycemic conditions, mitochondrial dysfunction in retinal endothelial cells triggers excessive reactive oxygen species/reactive nitrogen species production, barrier protein degradation, and endothelial barrier breakdown in diabetic retinopathy.

Photoenergy transduction in halobacterium halobium [PDF]

open access: yes
The structure and function of a rhodopsin-like pigment bacteriorhodopsin, discovered and isolated from the membranes of the halophile Halobacterium halobium, were studied.

Human Breast Milk‐Derived Exosomal FP671120.4 Inhibits Macrophage M1 Polarization via Modulating the ELAVL1/Nrf2 Axis in Sepsis‐Associated Liver Injury

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Sepsis‐associated liver injury (SALI) plays a major role in aggravating disease progression and worsening prognosis in patients with sepsis. Macrophage polarization is a key factor in the modulation of SALI progression. Recent studies have shown that human breast milk‐derived exosomes (HBM‐Exos) regulate processes involved in macrophage ...

Contribution to the theory of photopic vision: Retinal phenomena [PDF]

open access: yes
Principles of thermodynamics are applied to the study of the ultramicroscopic anatomy of the inner eye. Concepts introduced and discussed include: the retina as a three-dimensional sensor, light signals as coherent beams in relation to the dimensions of ...

Involvement of the miR‐128‐3p/KDM3A/NLRP3 Axis in High Glucose‐Induced Inflammatory Injury in Retinal Endothelial Cells

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study explores the regulatory mechanism of the miR‐128‐3p in diabetic retinopathy (DR)‐associated inflammatory injury. A cellular model of DR was established by inducing immortalized human retinal endothelial cells (IM‐HRECs) with high‐glucose (HG).
