Immunity against Non-Melanoma Skin Cancer and the Effect of Immunosuppressive Medication on Non-Melanoma Skin Cancer Risk in Solid Organ Transplant Recipients

open access: yesCells, 2023
Non-melanoma skin cancers (NMSCs) occur frequently in the Caucasian population and are considered a burden for health care. Risk factors include ultraviolet (UV) radiation, ethnicity and immunosuppression. The incidence of NMSC is significantly higher in

Attachment of −tBu groups to aza-BODIPY core at 3,5-sites with ultra-large Stokes shift to enhance photothermal therapy through apoptosis mechanism

open access: yesMaterials Today Bio, 2022
By the introduction of the −tBu groups into aza-BODIPY core, di-tert-butyl-substituted aza-BODIPYs at 3,5-sites (tBuazaBDPs) were prepared for the first time. Based on the X-ray analysis of CN-tBuazaBDP, this molecular structure is twisted. Near-infrared

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.

Targeting the PD-1/PD-L1 Axis in Human Vitiligo

open access: yesFrontiers in Immunology, 2020
Autoreactive CD8+ T cells play a pivotal role in melanocyte destruction in autoimmune vitiligo. Immunotherapy for melanoma often leads to autoimmune side-effects, among which vitiligo-like depigmentation, indicating that targeting immune checkpoints can ...

Biomarkers for Response of Melanoma Patients to Immune Checkpoint Inhibitors: A Systematic Review

open access: yesFrontiers in Oncology, 2017
BackgroundImmune checkpoint inhibitors (ICIs), targeting CTLA-4 or PD-1 molecules, have shown impressive therapeutic results. However, only 20–40% of advanced melanoma patients have durable responses to ICI, and these positive effects must be balanced ...

Studies on the antioxidative activity of red pigments in Italian-type dry-cured ham [PDF]

open access: yes, 2003
Aqueous phosphate buffer extracts and acetone/water extracts of pigments from Parma ham were assessed as antioxidants by (1) electron spin resonance spectroscopy using a spin probing technique to evaluate their efficiencies as scavengers of free radicals,

Macular pigment and its contribution to visual performance and experience

open access: yesJournal of Optometry, 2010
There is now a consensus, based on histological, biochemical and spectral absorption data, that the yellow colour observed at the macula lutea is a consequence of the selective accumulation of dietary xanthophylls in the central retina of the living eye.
