there are conflicting results concerning dc-sign and dc-signr vntr polymorphisms. the present study aimed to evaluate the possible association between dc-sign as well as dc-signr vntr polymorphisms and pulmonary tuberculosis (ptb) in a sample of iranian population. this case-control study was done on 171 ptb and 161 healthy subjects. the variants were detected by polymerase chain reaction (pcr)...

MOSFET is the most commonly used devices in DC-DC power converters, and its performance is important to the prognosis and health management of power. The paper proposes a degradation analysis model for MOSFET in DC-DC power converters. A method for detecting the degradation of MOSFET is also introduced. Simulations have shown that the method can predict deterioration in the performance of MOSFE...

Human Leukocyte Antigen-G (HLA-G) contributes to cancer cell immune escape from host antitumor responses. The clinical relevance of HLA-G in several malignancies has been reported. However, the role of HLA-G expression and functions in Acute Myeloid Leukemia (AML) is still controversial. Our group identified a subset of tolerogenic dendritic cells, DC-10 that express HLA-G and secrete IL-10. DC...

Brucella abortus is a facultative intracellular bacterium that infects humans and domestic animals. The enhanced susceptibility to virulent B. abortus observed in MyD88 knockout (KO) mice led us to investigate the mechanisms involved in MyD88-dependent immune responses. First, we defined the role of MyD88 in dendritic cell (DC) maturation. In vitro as well as in vivo, B. abortus-exposed MyD88 K...

The thermoelectric transfer difference of Thermal Converters (TCs) can be evaluated in both current mode and voltage mode, using a fast-reversed dc (FRDC) source. Some types of TCs show differences in the thermoelectric transfer difference between voltage and current mode as large as some parts in 10. In order to investigate the origin of the discrepancy, the change of the thermoelectric transf...

The ac susceptibility and magnetization curves of a glued Dy(2)O(3) powder sample are measured by an ac susceptometer and a dc superconducting quantum interference device magnetometer, both of which have been calibrated previously. It is shown that the magnetic moment of the paramagnetic sample as a function of field and temperature may be accurately expressed by a combination of the Curie-Weis...

A dendritic cell (DC) imbalance with a marked deficiency in CD4- 8+ DC occurs in non-obese diabetic (NOD) mice, a model of human autoimmune diabetes mellitus. Using a NOD congenic mouse strain, we find that this CD4- 8+ DC deficiency is associated with a gene segment on chromosome 4, which also encompasses non-MHC diabetes susceptibility loci. Treatment of NOD mice with fms-like tyrosine kinase...
