CIRRHOSIS WITH PIGMENTATION. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1901
The cases of cirrhosis of the liver with pigmentation of the skin or tissues, or of both together, constitute a small but most interesting group. There has been a great deal of speculation as to the etiology of these cases. The purpose of this paper is to present as briefly as possible the history of this form of cirrhosis, the clinical symptoms and ...

The effect of various nickel oxide ratios on the color and reflectivity of PY53 nickel-titanate yellow pigment

open access: yesResults in Chemistry, 2022
Complex inorganic nickel-titanate PY53 yellow pigments with a high thermal solar reflectance were synthesized. Four different compositions were made with increasing nickel oxide (NiO) ratios, with Sb2 O3 and TiO2 as the fixed components.

Cyclic nucleotide signaling as a drug target in retinitis pigmentosa

open access: yesFEBS Letters, EarlyView.
Disruptions in cGMP and cAMP signaling can contribute to retinal dysfunction and photoreceptor loss in retinitis pigmentosa. This perspective examines the mechanisms and evaluates emerging evidence on targeting these pathways as a potential therapeutic strategy to slow or prevent retinal degeneration.

Determination of ADP/ATP translocase isoform ratios in malignancy and cellular senescence

open access: yesMolecular Oncology, EarlyView.
The individual functions of three isoforms exchanging ADP and ATP (ADP/ATP translocases; ANTs) on the mitochondrial membrane remain unclear. We developed a method for quantitatively differentiating highly similar human ANT1, ANT2, and ANT3 using parallel reaction monitoring. This method allowed us to assess changes in translocase levels during cellular
