Malignant mesothelioma (MM) is a therapy-resistant cancer arising primarily from the lining of the pleural and peritoneal cavities. The most frequently altered genes in human MM are cyclin-dependent kinase inhibitor 2A (CDKN2A), which encodes components of the p53 (p14ARF) and RB (p16INK4A) pathways, BRCA1-associated protein 1 (BAP1), and neurofibromatosis 2 (NF2). Furthermore, the p53 gene (TP53) itself is mutated in ~15% of MMs. In many MMs, the PI3K-PTEN-AKT-mTOR signaling node is hyperactivated, which contributes to tumor cell survival and therapeutic resistance...

INTRODUCTION AND OBJECTIVE: Nonmelanoma skin cancers (NMSCs) are the most common malignancies in the United States. Surgery is the most common treatment for these tumors, but pre-operative identification of surgical margins is challenging. The objective in this study was to determine whether optical polarization imaging (OPI) could be used prior to surgery to detect the extent of subclinical tumor spread by monitoring disruption in collagen. MATERIALS AND METHODS: OPI is a non-invasive and rapid imaging modality that highlights the structure of dermal collagen...

Perianal basal cell carcinoma (BCC) is a rare lesion that accounts for less than 0.08% of all BCCs. It is challenging to diagnose, as it can be overlooked or mistaken for an inflammatory dermatosis. When discovered early and treated properly, BCC is associated with low mortality and a good prognosis. Thorough total-body skin examinations and biopsy of suspected lesions found in the perianal region is recommended. We present a case of a superficial nodular perianal BCC that was discovered following a routine total-body skin examination and was treated with Mohs micrographic surgery (MMS)...

Treatment of digital skin cancers is challenging due to various functional and cosmetic implications. Traditionally, routine treatment includes radical amputation, but digital skin cancers are increasingly being treated with more conservative, tissue-sparing methods such as Mohs micrographic surgery (MMS), which provides excellent tissue conservation and margin control when used to treat melanoma and nonmelanoma skin cancers (NMSCs). In this study, we conducted a retrospective chart review to evaluate clinical outcomes following MMS for treatment of digital melanoma and NMSCs...

We propose utilizing a rigorous registration model and a skyline-based method for automatic registration of LiDAR points and a sequence of panoramic/fish-eye images in a mobile mapping system (MMS). This method can automatically optimize original registration parameters and avoid the use of manual interventions in control point-based registration methods. First, the rigorous registration model between the LiDAR points and the panoramic/fish-eye image was built. Second, skyline pixels from panoramic/fish-eye images and skyline points from the MMS’s LiDAR points were extracted, relying on the difference in the pixel values and the registration model, respectively...

Statins are 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors, and this class of drugs has been studied as protective agents against DNA damages. Alkylating agents (AAs) are able to induce alkylation in macromolecules, causing DNA damage, as DNA methylation. Our objective was to evaluate atorvastatin (AVA) antimutagenic, cytoprotective, and antigenotoxic potentials against DNA lesions caused by AA. AVA chemopreventive ability was evaluated using antimutagenicity assays ( Salmonella /microsome assay), cytotoxicity, cell cycle, and genotoxicity assays in HepG2 cells...

BACKGROUND: Most skin cancers occur on the head and neck, areas of the body that are significant to an individual's body image (BI) perception. Poor BI is a robust risk factor for depression and decreased quality of life. Thus, patients with nonmelanoma head and neck skin cancer (NMHNSC) may be more vulnerable to BI disturbance and the negative sequelae of poor BI. OBJECTIVE: Describe the nature of BI concerns in patients diagnosed with NMHNSC and assess how BI changes with treatment...

CD59 is involved in lymphocyte signal transduction and regulates complement-mediated cell lysis by inhibiting the membrane attack complex. In the cases reported so far, congenital isolated CD59 deficiency was associated with recurrent episodes of hemolytic anemia, peripheral neuropathy, and strokes. Here, we report on a patient from a consanguineous Turkish family, who had a first episode of hemolytic anemia at one month of age and presented at 14 months with acute Guillain-Barré syndrome (GBS). The child suffered repeated infection-triggered relapses leading to the diagnosis of chronic inflammatory demyelinating polyneuropathy (CIDP)...

Condition-dependent genetic interactions can reveal functional relationships between genes that are not evident under standard culture conditions. State-of-the-art yeast genetic interaction mapping, which relies on robotic manipulation of arrays of double-mutant strains, does not scale readily to multi-condition studies. Here, we describe barcode fusion genetics to map genetic interactions (BFG-GI), by which double-mutant strains generated via en masse "party" mating can also be monitored en masse for growth to detect genetic interactions...
