Vertical Temperature Profiles with Light Breezes at Night in Urban and Rural Areas of Obuse, Nagano

This paper describes the vertical structure of the nocturnal heat island in a small town. Tethered balloon soundings were conducted 180 times in and around an urban area on nights with light winds from March 2003 to May 2005. Surface inversions developed not only in rural areas but also in urban areas. Surface inversions developed quickly after sunset at the rural site, whereas development was slower at the urban site. At six hours after sunset the verticaltemperature profile in the urban area was the same as that in the rural area. Heat island formation in the small town was related to the delay in the development of surface inversion in the urban area. The crossover effect can be seen in only three of 23 surveys for which vertical soundings were performed in both urban and rural areas

Characteristics of the Potential Temperature Distribution Along Mountain Slopes Experiencing Cross-Mountain Air Currents in the Winter Season

In winter, northwesterly winds in the vicinity of Japan are predominant in the winter pressure distribution pattern that characterizes the climate of the environs of Japan, and on the Kanto Plain cross-mountain air currents frequently occur in winter because the winds pass over the Joshin’etsu mountainous region. A detailed analysis of the cross-mountain air currents is important to understanding the climate in the northwestern inland region of the Kanto Plain on the leeward side. In addition, little research has been conducted on the role of the gap flow in regard to the winter cross-mountain air currents. To address this shortage, advanced meteorological observation was carried out along the channel traversing the Joshin’etsu mountainous region, and that data was used to research the characteristics of the surface atmosphere along the mountain slopes when winter cross-mountain air currents blow. As a result, in the case in which cross-mountain air currents were not blowing, the potential temperature along the mountain slope tended to rise with altitude, in both the Sea of Japan side and Pacific Ocean side. However, in the case in which cross-mountain air currents were blowing, the potential temperature distribution was nearly uniform on the slope of the leeward, Pacific Ocean side, regardless of elevation. The case in which cross-mountain air currents were blowing had characteristics similar to foehn. This also suggests an impact by gap winds that pass through the Uonogawa-Tonegawa channel

Modulation of cAMP levels by highâ fat diet and curcumin and regulatory effects on CD36/FAT scavenger receptor/fatty acids transporter gene expression

Curcumin, a polyphenol from turmeric (Curcuma longa), reduces inflammation, atherosclerosis, and obesity in several animal studies. In Ldlrâ /â mice fed a highâ fat diet (HFD), curcumin reduces plasma lipid levels, therefore contributing to a lower accumulation of lipids and to reduced expression of fatty acid transport proteins (CD36/FAT, FABP4/aP2) in peritoneal macrophages. In this study, we analyzed the molecular mechanisms by which curcumin (500, 1000, 1500 mg/kg diet, for 4 months) may influence plasma and tissue lipid levels in Ldlrâ /â mice fed an HFD. In liver, HFD significantly suppressed cAMP levels, and curcumin restored almost normal levels. Similar trends were observed in adipose tissues, but not in brain, skeletal muscle, spleen, and kidney. Treatment with curcumin increased phosphorylation of CREB in liver, what may play a role in regulatory effects of curcumin in lipid homeostasis. In cell lines, curcumin increased the level of cAMP, activated the transcription factor CREB and the human CD36 promoter via a sequence containing a consensus CREB response element. Regulatory effects of HFD and Cur on gene expression were observed in liver, less in skeletal muscle and not in brain. Since the cAMP/protein kinase A (PKA)/CREB pathway plays an important role in lipid homeostasis, energy expenditure, and thermogenesis by increasing lipolysis and fatty acid βâ oxidation, an increase in cAMP levels induced by curcumin may contribute to its hypolipidemic and antiâ atherosclerotic effects. © 2016 BioFactors, 43(1):42â 53, 2017Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/136289/1/biof1307_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/136289/2/biof1307.pd

Red thermoluminescence of enstatite from the Chainpur meteorite

For most ordinary chondrites feldspar is mainly responsible for thermoluminescence [TL], but in type 3 ordinary chondrites, especially those which are most primitive, other minerals are important. We observed red TL with a ∿660nm spectral peak in an ordinary chondrite, Chainpur (LL3.4). The mineral responsible for the red TL was identified as iron-free enstatite. Spatial distribution of TL and cathodoluminescence [CL] for the same specimen was also investigated, and it was found that the red TL areas corresponded to the high-sensitivity areas of red CL
