Ranjit G Gurav, Jingchun Tang, Jyoti P Jadhav
In black feathers, melanin is embedded in keratin matrix that makes feather more resistance to the microbial degradation. Chryseobacterium sp. RBT previously isolated from the poultry waste disposable site revealed strong sulfitolytic and keratinolytic activities. Maximum keratinase activity was observed at 48 h (89.12 U ml(-1)) showed 83 % of native black feather degradation. The concentration of free sulfhydryl groups released during degradation was 0.648 × 10(-4) M (12 h), 2.144 × 10(-4) M (96 h), and however, declined on prolong incubation to 1...

Wood industries and agricultural crops generate an inexhaustible supply of by-products like lignin, which constitutes an environmental problem. Increasing efforts have been done to find new applications for lignin. One of them is as a food additive, but its chemical nature makes it sensitive to browning which constitutes a major drawback for this type of lignin application. In the present study we are documenting how color stabilization of a commercial kraft lignin was achieved after the treatment with Penicillium chrysogenum var...

For fast and easy isolation of inhibitor-free genomic DNA even from the toughest plant leaf samples, including those high in polyphenols and polysaccharides, a protocol has been developed. To prevent the solubility of polysaccharides in the DNA extract, high salt concentration (1.4 M) was used in the extraction buffer. Polyvinylpyrrolidone (PVP) was used for the removal of polyphenols as polymerase chain reaction (PCR) inhibitors. Proteins like various enzymes were degraded by proteinase K and removed by centrifugation from plant extracts during the isolation process resulting in pure DNA and RNA ready to use in downstream applications including PCR, quantitative polymerase chain reaction (qPCR), ligation, restriction and sequencing...

People of color are at significantly higher risk in mortality from skin cancers, such as melanoma, than Caucasians. Around 4,500,000 people of color are affected by skin cancer The five-year survival rates from melanoma are 81.1% for Hispanics, 80.2% for Asians, 72.2% for African- Americans, and 89.6% for Caucasians. For this reason, it is important to ensure the scientific literature reflects the most up to date recommendations and treatment for blacks regarding skin cancer. Therefore the authors conducted a "gap analysis" on the current treatment of skin cancer in people of color...

The costs of diagnosing and treating basal cell carcinomas (BCC) and squamous cell carcinomas (SCC) are the highest of all cancers in Australia. However, information regarding incidence, multiplicity and risk are scarce as keratinocyte cancers (KCs) are not captured by most registries. To address these gaps, we initiated the QSKIN Study in 2010 recruiting 43,794 Queensland residents from a population register (participation 24%). Participants self-completed a baseline survey recording information on residential history, sun exposure, phenotype and medical and family history...

BackgroundLocalized cutaneous argyria is a rare skin condition caused by direct contact with silver or silver particles. It presents as asymptomatic gray or blue-gray macules that appear similar to blue nevi. Histologic features include brown-colored or black-colored silver granules in the basement membrane and dermis, most commonly surrounding eccrine glands, elastic fibers, and collagen fibrils. The condition is most frequently observed in individuals who are regularly exposed to small silver particles, such as silversmiths and welders...

Cross lip vermilion flap is a myomucosal flap that uses lower red lip to augment deficient upper lip vermilion. Technical note that helps in imitating upper lip tubercle structure is presented. Appropriate patient selection to prevent unfavorable results such as color mismatch, local vermilion excess, and lower lip thinning are presented. Indirect benefits of this flap for decreasing upper incisor tooth show and better balance of upper/lower lip thickness are discussed.

Strawberry fruits (Fragaria vesca) are valued for their sweet fruity flavor, juicy texture, and characteristic red color caused by anthocyanin pigments. To gain a deeper insight into the regulation of anthocyanin biosynthesis, we performed comparative metabolite profiling and transcriptome analyses of one red-fruited and two natural white-fruited strawberry varieties in two tissues and three ripening stages. Developing fruit of the three genotypes showed a distinctive pattern of polyphenol accumulation already in green receptacle and achenes...

Intelligent video surveillance systems detect pre-configured surveillance events through background modeling, foreground and object extraction, object tracking, and event detection. Shadow regions inside video frames sometimes appear as foreground objects, interfere with ensuing processes, and finally degrade the event detection performance of the systems. Conventional studies have mostly used intensity, color, texture, and geometric information to perform shadow detection in daytime video, but these methods lack the capability of removing shadows in nighttime video...

Transparent and flexible devices based on two-dimensional (2D) materials hold great potential for many electronic/optoelectronic applications. The direct and fast thickness identification of 2D materials on transparent substrates is therefore an essential step in such applications, but remains challenging. Here, we present a simple, rapid and reliable optical method to identify the thickness of 2D nanosheets on transparent substrates, such as polydimethylsiloxane, glass, and coverslip. Under reflection and transmission light, 1-20L MoS2 and 1-14L WSe2 nanosheets can be reliably identified by measuring the optical contrast difference between the 2D nanosheets and substrates in color, red, green or blue channels...

Numerous studies in psychology, cognitive neuroscience and psycholinguistics have used pictures of objects as stimulus materials. Currently, authors engaged in cross-linguistic work or wishing to run parallel studies at multiple sites where different languages are spoken must rely on rather small sets of black-and-white or colored line drawings. These sets are increasingly experienced as being too limited. Therefore, we constructed a new set of 750 colored pictures of concrete concepts. This set, MultiPic, constitutes a new valuable tool for cognitive scientists investigating language, visual perception, memory and/or attention in monolingual or multilingual populations...

Gold nanoparticles (AuNPs)-based colorimetric assays are of particular interest since molecular events can be easily read out with the color changes of AuNPs by naked eye. However, the molecular recognitions occur almost exclusively in the liquid phase, i.e., the interaction between target analytes and AuNPs is always proceeded in the presence of sample matrix. Since the aggregation of the unmodified AuNPs is prone to be influenced by the ionic strength of the solution, sample matrix will cause undesirable interference...
