Berberine alleviates cell pyroptosis in diabetic retinopathy by regulating AKT1, JUN, and STAT3
Ibrain, EarlyView.Berberine alleviates diabetic retinopathy by reducing pyroptosis through AKT1/JUN/STAT3 regulation, as validated in rat models via network pharmacology, molecular docking, and experimental assays. Abstract Berberine (BBR) exerts an effective protection for diabetic retinopathy (DR), but the underlying key molecular mechanism remains unknown; this study

Functional characterization of spectral tuning mechanisms in the great bowerbird short-wavelength sensitive visual pigment (SWS1), and the origins of UV/violet vision in passerines and parrots [PDF]
, 2013 BackgroundOne of the most striking features of avian vision is the variation in spectral sensitivity of the short wavelength sensitive (SWS1) opsins, which can be divided into two sub-types: violet- and UV- sensitive (VS & UVS).

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.ABSTRACT Across the animal kingdom, social behaviors such as aggression are critical for survival and reproductive success. While there is significant variation in social behaviors within and between species, the genetic mechanisms underlying natural variation in social behaviors are poorly understood.

The Kaohsiung Journal of Medical Sciences, EarlyView.ABSTRACT Effective glycemic control and food consumption play crucial roles in modulating diabetic retinopathy (DR) progression. This observational longitudinal study explored the hemoglobin A1c (HbA1c) and dietary patterns and their associations with the risk and progression of DR among 369 individuals with type 2 diabetes.

Airway Involvement in Conradi–Hünermann–Happle Syndrome: A Novel Clinical Manifestation
The Laryngoscope, EarlyView.We report the first documented case of airway involvement in Conradi–Hünermann–Happle syndrome (CDPX2), an X‐linked dominant form of chondrodysplasia punctata caused by pathogenic variants in EBP. A 2‐month‐old female with genetically confirmed CDPX2 developed severe subglottic stenosis and persistent respiratory distress requiring CPAP; cross ...
