BACKGROUND The WTC collapse exposed over 300,000 people to high concentrations of WTC-PM; particulates up to ∼50 mm were recovered from rescue workers' lungs. Elevated MDC and GM-CSF independently predicted subsequent lung injury in WTC-PM-exposed workers. Our hypotheses are that components of WTC dust strongly induce GM-CSF and MDC in AM; and that these two risk factors are in separate inflamm...
In this paper, a novel wavelet-based multiple description coding (MDC) is proposed with dual decomposition (DD) and cross packetization (CP). Through dual decomposition, each description has two parts, the primary and the complementary. The former contains the structural information, including the positions and signs of significant coefficients, whereas the latter contains the residual data, wh...
Exposure to ubiquitous allergens early in life, even before birth, may influence the incidence of allergic diseases later in life. During pregnancy, the fetomaternal interface is surrounded by high levels of T-helper (Th)2-like cytokines, possibly favouring the development of Th2-like immune responses in the offspring. The aim of this study was to evaluate the relation between cord blood (CB) I...
Motor learning studies face the challenge of differentiating between real changes in performance and random measurement error. While the traditional p-value-based analyses of difference (e.g., t-tests, ANOVAs) provide information on the statistical significance of a reported change in performance scores, they do not inform as to the likely cause or origin of that change, that is, the contributi...
background: falciparum malaria is a severe health burden worldwide. antigen presenting cells are reported to be affected by erythrocytic stage of the parasite. malarial hemozoin (hz), a metabolite of malaria parasite, has adjuvant properties and may play a role in the induction of immune response against the parasite. objective: to determine the immunological impact of hemozoin on the capacity ...
This paper proposes a video communication scheme combing the multiple description coding (MDC) using scalar quantizers with the matching pursuit (MP) to transmit the video over the Internet. The parameters obtained after MP, called atoms, are encoded into two balanced descriptions, which are transmitted over two separate channels. Simulation results show that our proposed method surpasses MP si...
Endmember extraction and spectral unmixing is a very challenging task in multispectral/hyperspectral image processing due to the incompleteness of information. In this paper, a new method for endmember extraction and spectral unmixing of hyperspectral images is proposed, which is called as minimum distance constrained nonnegative matrix factorization (MDC-NMF). After being compared with a newly...
The Klebsiella pneumoniae mdcR gene, which encodes a LysR-type regulator, was overexpressed in Escherichia coli. Purified MdcR was found to bind specifically to the control region of either the malonate decarboxylase (mdc) genes or mdcR. We have also demonstrated that MdcR is an activator of the expression of the mdc genes, whereas it represses the transcription of the putative control region o...
