A 61-year-old immunosuppressed renal transplant patient with inflammatory bowel disease presented with tender pink nodules on the trunk and extremities. An initial biopsy was suggestive of metastatic Crohn disease, but after disease persistence, a second biopsy revealed disseminated Mycobacterium haemophilum. Atypical mycobacterial infections should be considered in immunosuppressed patients. This case highlights the complexities of diagnosing such infections in patients with an underlying granulomatous condition and the particular growth requirements of M...

Methods for rapid detection of fecal indicator bacteria in water are important to ensure that water is safe for drinking, bathing, recreation, fishing and shellfish harvesting. In this study, we tested experimental conditions for bacterial hydrolysis of two promising enzymatic substrates, 5-Bromo-4-chloro-3-indolyl β-D-glucuronide (X-Gluc) and Resorufin β-D-glucuronide (REG), and optimized parameters such as temperature and pH to determine conditions for rapid reactions. We then innovated a membrane filter-based approach to facilitate more rapid enzyme-based detection of Escherichia coli in water based on the combination of an initial concentration step and optimized test conditions...

The pink shrimp, Farfantepenaeus duorarum is an important commercial species in the Gulf of Mexico, which supports significant commercial fisheries near Dry Tortugas, in Southern Florida and in Campeche Sound, Southern Gulf of Mexico. There is information about the nictemeral behavior of the pink shrimp related to sunset, what is crucial to more accurate estimation of shrimp population biomass, and to assess the potential of this resource and its proper management. To contribute to the knowledge and the population dynamics of the species, shrimp surveys were conducted in a nursery area near “El Cayo” in the Northeastern part of Terminos Lagoon, Mexico during October 2010...

An isolate of aerobic, Gram-stain-negative, rod-shaped, non-motile and light-pink pigmented bacteria, designated SBC68T , was obtained from slightly decomposed thalli of the lichen Cladonia sp. collected from the forested tundra of north-western Siberia. Cells of this isolate occurred singly, in pairs or in rosettes. These bacteria were acidophilic (optimum growth at pH 4.3-5.6) and mesophilic (optimum growth at 20-30 °C) but were also capable of growth at low temperatures, down to 7 °C. The preferred growth substrates were sugars, some organic acids and lichenan...

Mature male Pacific salmon (Oncorhynchus spp.) develop a hooknose, as a secondary male sexual characteristic, during the spawning period. It is likely that androgens regulate hooknose formation. However, endocrinological and histochemical details about the relationship between androgens and hooknose formation are poorly understood. In this study, we performed assays of serum androgens, detection of androgen receptor (AR) in hooknose tissues, external morphological measurement of hooknose-related lengths, and microscopic observation of hooknose tissues of pink salmon (O...

External cervical root resorption begins at the root surface as result of odontoclastic activity in the cervical area and is progressive in character. The pulp is only affected at a later stage of the process. The aetiology and pathogenesis of external cervical root resorption is not fully understood. Possible predisposing factors are, among others, orthodontic treatment, trauma, internal bleaching, damaged cemento-enamel junction, bruxism and hypoxia. A 'pink spot' often is the first clinical sign and a two-dimensional radiograph usually presents an amorphous radiolucency with undefined borders...

In this study, 8 inch-wafer scale flexible polarization-dependent color filters with Ag-TiO2 composite nanowires have been fabricated using nanoimprint and E-beam evaporation. The filters change their color via a simple rotation of the polarizer. In addition, the color of the filter can be controlled by altering the thickness of the Ag and TiO2 nanowires deposited on the polymer patterns. Polarization-dependent color filters were realized by selective inhibition of the transmission spectra using plasmonic resonance at the insulator/metal/insulator nanostructure interface, which occurs at particular wavelengths for the transverse magnetic polarizations...

We report the design and synthesis of a novel chemosensor (Rh6G-Cin) rhodamine-based indicator for selective detection of Zn2+ ion. Rh6G-Cin displayed high selectivity towards Zn2+ from various metal ions, including Ca2+, Ag+, Cd2+, Co2+, Cu2+, Al3+, Zn2+, Cr3+, Ba2+, Fe2+, Fe3+, Gd3+, Hg2+, Mg2+, Mn2+, Nd3+, Pb2+, Sr2+ and Ni2+, and the resultant complex is [Rh6G-Cin-Zn2+]. The obvious change from colorless to pink upon the addition of Zn2+ could make it a suitable "naked eye" indicator for Zn2+...

The basal media M199 or MEM was utilized in the classical method of vitro culture of glochidia where 1-5% CO2 was required to maintain stable physiological pH for completion of non-parasitic metamorphosis. The classical method encounters a great challenge to those glochidia which undergo development of visceral tissue but significantly increase in size during metamorphosis. The improved in vitro culture techniques and classical methods were firstly compared for non-parasitic metamorphosis and development of glochidia in pink heelsplitter...

Although peanut (Arachis hypogaea L.) is one of the most important edible oil crops globally, pigments present in the testa influence both the processing efficiency and the quality of the oil. In peanut, polymeric phenolic compounds are present in the episperm rather than in the endothelium and their levels increase during ripening; therefore, to better understand testa development, and especially the accumulation of pigments, RNA-Seq was applied to elucidate the mechanisms underlying the regulation of peanut testae at three different developmental stages (i...
