Many insect pigments are localized in subcellular pigment granules, and transport of pigment precursors from the cytoplasm is accomplished by ABC proteins. Drosophila melanogaster has three half-transporter genes (white, scarlet, and brown, all affecting eye pigments) and Bombyx mori has a fourth (ok). The White, Brown, Scarlet and Ok proteins each have one transmembrane and one cytoplasmic dom...

A detailed, methodical approach was used to synthesise silver and gold nanoparticles using two differently prepared aqueous extracts of the brown algae Sargassum incisifolium. The efficiency of the extracts in producing nanoparticles were compared to commercially available brown algal fucoidans, a major constituent of brown algal aqueous extracts. The nanoparticles were characterised using TEM,...

To understand the mechanism of fiber development and pigmentation formation, the mRNAs of two cotton lines were sequenced: line Z128 (light brown fiber) was a selected mutant from line Z263 (dark brown fiber). The primary walls of the fiber cell in both Z263 and Z128 contain pigments; more pigments were laid in the lumen of the fiber cell in Z263 compared with that in Z128. However, Z263 contai...

By use of targeted oncogenesis, a brown adipocyte cell line was derived from a hibernoma of a transgenic mouse carrying the proximal promoter of the human mineralocorticoid receptor (MR) linked to the SV40 large T antigen. T37i cells remain capable of differentiating into brown adipocytes upon insulin and triiodothyronine treatment as judged by their ability to express uncoupling protein 1 and ...

We present spectroscopic and imaging observations of the active T dwarf 2MASS 1237+6526, intended to investigate the emission mechanism of this cool brown dwarf. The Hα emission line first detected in 1999 July appears to be persistent over 1.6 years, with no significant variation from log10(LHα/Lbol) = −4.3, ruling out flaring as a possible source. The relatively high level of emission in this...

© 2017 Indian Dermatology Online Journal | Published by Wolters Kluwer Medknow A 24‐year‐old man presented with a single asymptomatic reddish‐brown annular plaque of 8‐months duration over the outer right arm [Figure 1]. Dermoscopy revealed a central homogenous skin‐colored to pale area with brown‐colored dots, globules, and an irregular double‐marginated track‐like border, most prominent aroun...

BACKGROUND As a result of changing consumer preferences, cotton (Gossypium Hirsutum L.) from varieties with naturally colored fibers is becoming increasingly sought after in the textile industry. The molecular mechanisms leading to colored fiber development are still largely unknown, although it is expected that the color is derived from flavanoids. EXPERIMENTAL DESIGN Firstly, four key genes...

Miglitol is an alpha-glucosidase inhibitor that improves post-prandial hyperglycemia, and it is the only drug in its class that enters the bloodstream. Anecdotally, miglitol lowers patient body weight more effectively than other alpha-glucosidase inhibitors, but the precise mechanism has not been addressed. Therefore, we analyzed the anti-obesity effects of miglitol in mice and in the HB2 brown...

We present ALMA continuum and spectral line observations of the young Brown Dwarf ρ-Oph 102 at about 0.89 mm and 3.2 mm. We detect dust emission from the disk at these wavelengths and derive an upper limit on the radius of the dusty disk of ∼ 40 AU. The derived variation of the dust opacity with frequency in the mm provides evidence for the presence of mm-sized grains in the disk outer regions....

Aphanius marassantensis, new species, is described from the Kızılırmak River drainage in northern Anatolia based on colouration, meristic and morphometric characters, and the mtDNA COI barcode region. It is distinguished from other Anatolian Aphanius by one or several of the following characters: a stout body shape (BD/SL 28.2-39.6%), complete scale cover, and 25-28 scales along the lateral lin...
