In mammals, two types of adipose tissue are present, brown and white. They develop sequentially, as brown fat occurs during late gestation whereas white fat grows mainly after birth. However, both tissues have been shown to have great plasticity. Thus an apparent transformation of brown fat into white fat takes place during post-natal development. This observation raises questions about a possi...

Wolbachia species are intracellular symbionts that cause reproductive alterations in arthropods. Transinfection experiments have been performed in many arthropod species to elucidate the interaction betweenWolbachia and a new host. To ease transinfection of this bacterium to new arthropodhosts,we introduced two techniques: nymphal injection insteadof embryonic injection and the use of a culture...

Introduction The circumlineatus gene (C/) was discovered by R. Prakken (1972). Circumlineatus is recessive and is expressed in partly colored seed coats (0 with restricted patterns, such as virgarcus. Cl was discovered in a cross between 'White J' {Tz cl Rk) x 'Soldaat K' (/ z Cl rlâ) and is denoted by a ''precipitation line" (Prakken, 1972) demarcating the boundaiy between the white and colore...

Hot methane spectra are important in environments ranging from flames to the atmospheres of cool stars and exoplanets. A new spectroscopic line list, 10to10, for (12)CH4 containing almost 10 billion transitions is presented. This comprehensive line list covers a broad spectroscopic range and is applicable for temperatures up to 1,500 K. Previous methane data are incomplete, leading to underesti...

Iron is an essential micronutrient for human nutrition and polished rice contains very low amount of iron. Rice with high iron content in seed endosperm has been developed by insertion of soybean ferritin gene under the control of the endosperm specific glutelin promoter into the genome of indica rice line IR68144. The nutritional composition of the brown and milled rice grain has been compared...

The layer poultry is an important activity for food production with high biological value. Measuring egg quality has great relevance to ensure safety and products consumers. Thus, the objective was evaluate physical of four laying hen’s strains. Were used 864 eggs from hens’ lines (Hisex Brown®, Hy-Line Isa Label®, Lohmann Brown®). experimental design completely randomized composed treatments (...

Cool Land T-type objects were discovered first as companions to stars in 1988 and 1995, respectively. A certain example of the yet cooler Y-type spectral class (Te f f.500 K?) has not been seen. Recent infrared imaging observations of stars and brown dwarfs indicate that substellar companions with large semi-major axes and with masses less than the brown dwarf/giant planet dividing line (∼13.5 ...

We report on the first dedicated monitoring campaign of spectroscopic variability in young brown dwarfs. High-resolution optical spectra of six targets in nearby star-forming regions were obtained over 11 nights between 2005 JanuaryMarch on the Magellan 6.5m telescope. We find significant variability in Hα and a number of other emission lines related to accretion and outflow processes on a vari...

Brown adipose tissue (BAT) cells have a very high oxidative capacity. On the other hand, in obesity and obesity-related diabetes, levels of pro-inflammatory cytokines are elevated, which might promote BAT dysfunction and consequently impair carbohydrate metabolism and thereby exacerbate cellular dysfunction and promote diabetes progression. Therefore, the antioxidative enzyme status of a brown ...
