Investigation into the potential of methylene blue and its derivatives to be used in the photodynamic therapy of non-pigmented and pigmented cells
Photodynamic therapy (PDT) is a novel treatment for malignant disease. The first step is intravenous injection of a light-absorbing, cytotoxic drug (the photosensitizer) that is then allowed time to accumulate in malignant tissue. The second step involves local activation of the photosensitizer …

Quantitative analysis of neuropilin-2 expression in pigmented lesions and melanoma
The prevalence of skin cancer has been continuously increasing in the American population over the last 3 decades. Melanoma, the most serious and dangerous form, causes the most skin cancer related deaths. If melanoma is found early enough, it can be treated and cured. Current therapy for melanoma …

GENOME EDITING, A NEW BIOTECNOLOGICAL APPROACH TO PRODUCE LYCOPENE-RICH PIGMENTED ORANGES
Il consumo di frutti ricchi in composti antiossidanti è fortemente apprezzato dai consumatori, essendo noti i loro effetti benevoli per la salute umana, grazie alla loro abbondanza in sostanze ad alto valore nutrizionale e nutraceutico. Tuttavia, in natura, non esistono frutti di agrumi ricchi in …

MicroRNA Expression Signature of Retinal Pigmented Epithelial Cells Associated with the Phenotype of Age-Related Macular Degeneration
… stress-related apoptosis of first the retinal pigmented epithelium (RPE) and then the photoreceptors. MicroRNAs (miRNAs) are a group of endogenous noncoding RNA molecules that originate from parts of the genome that were originally speculated to be “junk” DNA. However, it is now known that …

ROLE OF THE ROOTSTOCK IN INFLUENCING FRUIT QUALITY AND TOLERANCE TO SALT STRESS IN PIGMENTED CITRUS SPECIES
L’agricoltura è uno dei principali settori dell'economia del Mediterraneo e italiana e gli agrumi sono la prima coltura frutticola in termini di produzione mondiale con 157 milioni di tonnellate. Il portinnesto ha svolto per centinaia di anni un ruolo determinante sulla produzione, sulla qualità …

Differential gene expression analysis reveals functional roles of cryptic orange-pigmented organ in the colorless head kidney of Antarctic icefishes
We discovered an orange-pigmented, discrete body several millimeters in size embedded within the anterior end of the colorless head kidney of the hemoglobinless Antarctic icefishes. No macroscopically visible discrete organ has previously been reported in Antarctic fishes or teleost fishes in …

DARK-PIGMENTED, AMOXICILLIN-RESISTANT, BACTERIAL SPECIES IN CHRONIC PERIODONTITIS MICROBIOTA IDENTIFIED WITH MATRIX ASSISTED LASER DESORPTION/IONIZATION TIME-OF-FLIGHT MASS SPECTROMETRY.
Dark-pigmented, gram-negative, anaerobic rods are often recovered in large numbers from the subgingival microbiome of human periodontitis, and are statistically associated with progression of chronic periodontitis. Due to their frequent expression of beta-lactamase enzymes, which hydrolyze and …

In vitro evaluation of Ultraviolet Radiation (UVR) exposure of the Retinal Pigmented Epithelium (RPE) and its relevance to Age-Related Macular Degeneration (AMD)
… to explore the response of cultured retinal pigmented epithelium (RPE), the loss of which heralds advanced AMD, to specific wavelengths of UVR across the UV-B and UV-A bands. METHODS: Using a custom built in vitro UVR exposure apparatus coupled with bandpass filters we exposed the …

Endogenous short interfering RNAs that silence chalcone synthase result in pigment pattern formation on soybean seed coats
… homozygous recessive i allele results in fully pigmented seed. Previous work showed that dominant alleles correspond to duplications of chalcone synthase (CHS) genes leading to production of CHS siRNAs which in turn degrade CHS mRNAs resulting in yellow seed coats (Tuteja et al., 2009 and Vodkin …

Survival of Antarctic Bacteria Exposed to Ultraviolet and Visible Light
… from six meters depth, 70T and 71T, were pigmented and extracts of these pigmented organisms showed absorption spectra characteristic of carotenoid pigments (450-550 nm). The two isolates from a depth of 18 meters, 64T and 21B were colorless. All strains except 64T were catalase positive. …

Spread of White Hypovirulent Strains of Cryphonectria Parasitica Among American Chestnut Trees at the Lesesne State Forest
… with a mixture of dsRNA-containing white and pigmented hypovirulent strains. Grafted trees exhibited a high level of blight control, and all bark cores extracted from cankers on the grafted trees showed superficial necrosis. Bark cores extracted from these cankers yielded 156 isolates of C. …

The use of in vitro 2d co-culture models to determine the optimal keratinocyte: melanocyte ratio to be used in the development of pigmented 3d skin model
… of an ideal 3D skin equivalent. Therefore pigmented 3D skin constructs are of great interest as they address not only the issues of complete wound healing, but also the aesthetic outcomes. In light of this, correct keratinocyte to melanocyte ratios are also of great importance in designing …

Cultural characteristics, vegetative compatibility, and spatial pattern of white hypovirulent strains of Cryphonectria parasitica on grafted American chestnut trees
… a mixture of four European (white), and six, pigmented hypovirulent strains of Cryphonectria parasitica. A total of 202 C. parasitica isolates were recovered from 49 cankers located outside of the inoculated zone. Ninety-five isolates (47%) were white and 107 (53%) were pigmented. Forty-eight …

A study of the function of carotenoid pigments of a red psychrophilic micrococcus from Antarctica
… (180 to 300 nm). The spectrum of the typically pigmented culture showed that absorption maxima occurred at 210, 260, 320, 370, 390, 445, 465, 495 and 530 nm, with major maxima at 465, 495 and 530 nm, indicating presence of lycopene or other related compounds. Spectra from a white phenotype which …
