To further elucidate the migration history of the brown bears (Ursus arctos) on Hokkaido Island, Japan, we analyzed the complete mitochondrial DNA (mtDNA) sequences of 35 brown bears from Hokkaido, the southern Kuril Islands (Etorofu and Kunashiri), Sakhalin Island, and the Eurasian Continent (continental Russia, Bulgaria, and Tibet), and those of four polar bears. Based on these sequences, we ...

The galactic center compact radio source Sgr A was discovered on 13 and 15 February 1974 by Bruce Balick and Robert L. Brown using the Green Bank 35 km radio link interferometer (Balick & Brown 1974). We discuss other observations of this source in the years 1965-1985. Early VLBI observations are described. The name Sgr A was first used by Robert L. Brown (1982) and has become the accepted name...

That adult humans possess brown fat is now accepted - but is the brown fat metabolically active? Does human brown fat actually combust fat to release heat? In this issue of the JCI, Ouellet et al. demonstrate that metabolism in brown fat really is increased when adult humans are exposed to cold. This boosts the possibility that calorie combustion in brown fat may be of significance for our meta...

The molecular clock is intimately linked to metabolic regulation, and brown adipose tissue plays a key role in energy homeostasis. However, whether the cell-intrinsic clock machinery participates in brown adipocyte development is unknown. Here, we show that Bmal1 (also known as ARNTL), the essential clock transcription activator, inhibits brown adipogenesis to adversely affect brown fat formati...

brown trout, salmo trutta fario, has a wide range of distribution in the north of iran and in karaj, lighvanchai and karun rivers, but there is no report about its feeding behavior in some water resources including the lar natural park. in order to study feeding behavior of this fish during spawning season, a survey was carried out in the rivers of elarm, aab-sefid, kamardasht and delichayi in ...

background: cryptosporidiosis is a zoonotic disease with public health importance, especially for individuals with weak immune system, such as children, elderly people and immune suppressed ones. evaluation of the prevalence of cryptosporidium in wild rodents such as wild brown rats could help to establish an epidemiological map of cryptosporidiosis. the aim of the current study was to assess t...

1. In 125 cases of perirenal fat samples derived from human necropsies (from 1 month to 86 years), the occurrence of the brown adipose tissue was examined. Brown fat cells were contained in 72% (90: 125) of the cases. 2. In the infants, all samples contained maximal amounts of brown fat cells: the perirenal fat was composed almost exclusively of brown fat cells: in children and teenagers they b...

Case: A 54-year-old woman was visited with a history of asymptomatic gray-brown discoloration of the facial skin at our dermatology clinic. The lesions first appeared on her chin and then became progressively darker and extended to her nose and, to a lesser extent, to the periphery of her face over a period of five years. She mentioned that the lesions worsened with heat and sun exposure. Her p...

Complicities and complexities in racialization simultaneously create possibilities foreclose opportunities for cross-racial solidarities. In this auto-ethnographic paper, we share our learning theorizing of Brown-Black solidarities since filmed a webinar titled, “Brown Complicity White Supremacy: Towards Solidarity Black Lives” (SultyDee, 2020), one several efforts towards Brown (South Asian)-B...
