CONCLUSIONS |
Significant increments were observed in the optical density of the affected dentin after three months compared to that of healthy dentin in primary molars treated using the partial carious dentin removal technique.[Temperature modifications in shantytown environments and thermal discomfort]. |
OBJECTIVE |
To study aspects of the microclimate in a shantytown (favela), in order to understand the influence of the land occupation pattern on its climatic parameters. |
METHODS |
The study was carried out in a shantytown located in the southwestern region of the city of São Paulo, Brazil, between February 19 and July 31, 2003, i.e. covering the whole autumn and parts of the summer and winter. The air temperatures were measured every hour on a microclimate scale, at four points within this dense... |
RESULTS |
In the summer, the average hourly temperatures in the shantytown were between 18.5 degrees C and 29.5 degrees C but, away from it, they were 2 degrees C to 3 degrees C lower at the hottest times of the day. In the autumn, the temperatures ranged from 15.5 degrees C to 25.5 degrees C and in the winter, 13.5 degrees C to... |
CONCLUSIONS |
The land occupation is a temperature differentiation factor. In the shantytown, the temperatures were higher during the daytime (by up to 3 degrees C) and lower at nighttime (by 1 degrees C on average). The shantytown environment accentuated the temperature extremes, while the temperatures in the control street were mi... |
It is needless to emphasize the impact which the so called absolute bases carry on the nuclear Frechet spaces, and vice-versa. During the past ten or fifteen years, a number of deep and interesting results have been obtained in this direction, for instance one may consult [5], [9], [18], [20] and [23] and numerous refe... |
OBJECTIVE |
To detect the expression of long intergenic non-coding ribonucleic acid (LINC) 01535 in esophageal squamous cell cancer (ESCC) tissues and cells, and to investigate the influences of LINC01535 on the proliferation and apoptosis of ESCC cells and the possible mechanism. |
PATIENTS AND METHODS |
Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to determine the relative expression of LINC01535 in 43 cases of ESCC tissues and human esophageal cancer cells (KYSE30, EC9706, TE-13, and Ecal09) compared with human esophageal mucosal epithelial cells (HET-1A). The esophageal cancer cells with ... |
RESULTS |
LINC01535 expression in ESCC tissues and cells was remarkably higher than that in para-carcinoma tissues and esophageal mucosal epithelial cells. Knockdown of LINC01535 decreased proliferative capacity, arrested cell cycle in G1/G0 phase, and increased apoptotic rate of ESCC cells. The expressions of the molecular mark... |
CONCLUSIONS |
The expression of LINC01535 is up-regulated in ESCC tissues and cells, and the highly expressed LINC01535 promotes the proliferation and inhibits the apoptosis of ESCC cells by regulating the JAK/STAT3 signaling pathway. Our findings provide new directions for the diagnosis and treatment of esophageal cancer.ENVIRONMEN... |

In string theory the coupling “constants” appearing in the low-energy effective Lagrangian are determined by the vacuum expectation values of some (a priori) massless scalar fields (dilaton, moduli). This naturally leads one to expect a correlated variation of all the coupling constants, and an associated violation of ... |
