Photodynamic therapy (PDT), using 5-aminolevulinic acid (ALA) to drive synthesis of protoporphryin IX (PpIX) is a promising, scar-free alternative to surgery for skin cancers, including squamous cell carcinoma (SCC) and SCC precursors called actinic keratoses (AK). In the United States, PDT is only FDA approved for treatment of AK; this narrow range of indications could be broadened if PDT efficacy were improved. Toward that goal, we developed a mechanism-based combination approach using 5-fluorouracil (5-FU) as a neoadjuvant for ALA-based PDT...

We present a woman aged 50 years who underwent a Tru-cut biopsy for a BI-RADS 4 lesion on her right breast and received a histopathology diagnosis of a fibroadenoma. In her one year follow-up, the lesion had progressed and she underwent an excisional biopsy. Her final diagnosis was a periductal stromal tumor. Periductal stromal tumor is an extremely rare and different entity from phylloides tumor, which makes appropriate diagnosis difficult in Tru-cut biopsy and care should be taken. Lesion progression of should require a re-biopsy...

Shoot regeneration in safflower (Carthamus tinctorius 'AKS 207' and 'PKV Pink') genetically transformed using Agrobacterium was used for assessing various constraints to the efficiency of transformation including infection period, virulence induction medium, co-cultivation period, bacterial titre, selection regime, and the natural phenolic compound acetosyringone. Transformation frequency was promising with 8-10-day-old cotyledonary leaf explants. Therefore, explants of that age cultured on Agrobacterium minimal medium (AB) containing 100 µM acetosyringone were infected with Agrobacterium (cell titre 0...

Cutaneous squamous cell carcinoma (cuSCC) comprises 15-20% of all skin cancers, accounting for over 700,000 cases in the U.S. annually. Most cuSCC arise in association with a distinct precancerous lesion, the actinic keratosis (AK). In order to identify potential targets for molecularly targeted chemoprevention, we performed integrated cross-species genomic analysis of cuSCC development through the preneoplastic AK stage using matched human samples and a solar UV- driven Hairless mouse model. We performed RNA-seq and microRNA-seq on samples from both patients undergoing Mohs surgery and the mouse model...

Actinic keratoses (AKs) are frequently treated in the U.S., impacting an estimated 40 million people in 2004 and costing over $1 billion annually. AKs are a major public health concern because of their high prevalence, substantial cost, and potential for malignant transformation to keratinocyte carcinoma (KC). In this analysis, predictors of AK count were explored using pre-randomization baseline data from two large randomized trials of veterans with multiple prior KCs (n=932 and n=1131). Multivariate analyses were conducted to elucidate associations between AK count and several demographic and health related factors...

Actinic keratoses (AK) are common, costly, and may evolve to keratinocyte carcinoma (KC): basal cell (BCC) and squamous cell carcinoma (SCC) of the skin. Time to malignant transformation is controversial. We used data from the placebo arm (n=166) of a randomized trial of veterans with multiple prior KCs. Study dermatologists examined participants' faces/ears at enrollment and semiannual visits. Clinically diagnosed AKs were marked, photographed, and treated with cryotherapy (starting at 6 months). Lesions suspicious for KC were marked, photographed, and biopsied...

Cutaneous field cancerization (CFC) is associated witha high-risk of developing cutaneous squamous cellcarcinoma (cSCC). It manifests as actinic keratoses(AK) as one of the few macroscopic alterations in CFCpatients. A prospective, single-arm, case-series wasperformed to evaluate the utility of a novel sunscreencontaining DNA-photolyase for treatment of CFCin nine subjects (mean age 70.6 years, male: femaleratio 5:4). The cream was applied topically twicedaily on CFC/AK areas and patients were followedup for three months, with no other treatments...

Thyroiditis and autoantibodies to thyroglobulin (TgAb) and thyroid peroxidase (TPOAb) develop spontaneously in NOD.H2h4 mice, a phenotype enhanced by dietary iodine. NOD.H2h4 mice were derived by introducing the Major Histocompatibility Class (MHC) molecule I-Ak from B10.A(4R) mice to non-obese diabetic (NOD) mice. Apart from I-Ak, the genes responsible for the NOD.H2h4 phenotype are unknown. Extending serendipitous observations from crossing BALB/c to NOD.H2h4 mice, thyroid autoimmunity was investigated in both genders of the F1, F2 and the second generation backcross of F1 to NOD...

Predicting fire spread and behavior correctly is crucial to minimize the dramatic consequences of wildfires. However, our capability of accurately predicting fire spread is still very limited, undermining the utility of such simulations to support decision-making. Improving fire spread predictions for fire management purposes, by using higher quality input data or enhanced models, can be expensive, unfeasible or even impossible. Fire managers would benefit from fast and inexpensive ways of improving their decision-making...

BACKGROUND: The clinical features of Acanthamoeba keratitis (AK) are non-specific and closely resemble bacterial, viral and fungal keratitis. MATERIALS AND METHODS: We compared loop-mediated isothermal amplification (LAMP) with microscopy, non-nutrient agar (NNA) culture and polymerase chain reaction (PCR) in clinical suspects of AK. RESULTS: Of 52 clinical samples (42 AK suspects and 10 proven bacterial, viral or fungal keratitis), 3 were positive by direct microscopy (sensitivity 60%, confidence interval [CI]: 17%-92...

<p>Dermatologists treat actinic keratosis (AK) primarily because these lesions have the potential to progress to invasive squamous cell carcinoma. Patients, on the other hand, generally seek treatment to remove the lesions and achieve an improved appearance of their skin following treatment. In selecting a treatment option for AK, dermatologists should consider post-treatment cosmesis, because cosmetic outcomes differ across AK treatments. To obtain expert opinion on the cosmetic sequelae related to chronically photodamaged skin and the treatment of AK, an expert panel meeting among dermatologists was conducted in February 2016...

<p>Ingenol mebutate gel, a topical field treatment for actinic keratosis (AK), elicits inflammatory application-site reactions in most patients. This analysis explored the relationship between the intensity of local skin reactions (LSRs) and AK clearance, measured by the reduction in AK count from baseline in 218 patients who were treated for AK on the face in the pivotal Phase 3 studies. The analysis modeled the AK count at week 8, adjusted for baseline count, with the composite LSR score at 1 day after the last treatment application for each patient as a predictor to estimate the mean and 90% prediction interval for the percent reduction in AK count...

By investigating the optoelectronic properties of prototypical graphene/hexagonal boron nitride (h-BN) heterostructures, we demonstrate how a nanostructured combination of these materials can lead to a dramatic enhancement of light-matter interaction and give rise to unique excitations. In the framework of ab initio many-body perturbation theory, we show that such heterostructures absorb light over a broad frequency range, from the near-infrared to the ultraviolet (UV), and that each spectral region is characterized by a specific type of excitations...

At least 6 clinical studies conducted in subjects with actinic keratosis (AK) have demonstrated the therapeutic effect of Eryfotona AK-NMSC(®) (ISDIN, Spain), a topically applied film-forming cream containing DNA Repairsomes(™) (broad-spectrum UV filters and the DNA-repair enzyme photolyase, encapsulated in liposomes) (1-6) (registered as medical device in Europe). Recently a German opinion paper reviewed clinical evidence for the efficacy of topical application of this topical cream. They concluded that there was strong evidence that patient at high risk for developing AK would benefit from the year around use of this product marketed in Europe in the medical device category...
