Increased expression of the Mr 67,000 laminin receptor (LR) is a consistent event which appears as cancer cells acquire an invasive and metastatic phenotype. The Mr 67,000 LR is one of the many laminin-binding proteins able to interact with the major glycoprotein of basement membranes, laminin. The recent development of a specific monoclonal antibody directed against the Mr 67,000 LR MLuC5 has ...
Many animals have genetically determined left-right (LR) asymmetry of their internal organs. The midline structure of vertebrate embryos has important roles in LR asymmetric development both as the signaling center for LR asymmetry and as a barrier to inappropriate LR signaling across the midline. However, in invertebrates, the functions of the midline in LR asymmetric development are unknown. ...
In this paper we propose a novel face image super-resolution (SR) method named Locality-induced Support Regression (LiSR). Given a low-resolution (LR) input patch, we learn a mapping function between the local support LR and high-resolution (HR) patch pairs to predict its HR version. The support can be obtained from the LR or HR patch manifolds, which leads to two varieties of LiSR, namely LR p...
BACKGROUND A low level of response (LR) to alcohol is an important endophenotype associated with an increased risk of alcoholism. However, little is known about how neural functioning may differ between individuals with low and high LRs to alcohol. This study examined whether LR group effects on neural activity varied as a function of acute alcohol consumption. METHODS A total of 30 matched h...
The cyclic peptide toxins microcystins and nodularins are the most common and abundant cyanotoxins present in diverse water systems. They have been the cause of human and animal health hazard and even death. Microcystn-LR (MC-LR) is the most common and toxic among the micrcoystin variants. The physiological effects of MC-LR have not been adequately addressed. We report here the results of our s...
Microcystin-LR is the most toxic and the most frequently encountered toxin produced by the cyanobacteria in the contaminated aquatic environment. Previous studies have demonstrated that Microcystin-LR is a potential carcinogen for animals and humans, and the International Agency for Research on Cancer has classified Microcystin-LR as a possible human carcinogen. However, the precise molecular m...
When faced with a patient with acute chest pain, clinicians must distinguish myocardial infarction (MI) from all other causes of acute chest pain. If MI is suspected, current therapeutic practice includes deciding whether to administer thrombolysis or primary percutaneous transluminal coronary angioplasty and whether to admit patients to a coronary care unit. The former decision is based on ele...
Several NAC transcription factors promote lateral root (LR) numbers in Arabidopsis through the auxin signaling pathway. In soybean, a majority of genotypes increased LR number in response to water deficit. It is possible that drought inducible soybean NAC may be involved in the regulation of this enhanced LR number. Two drought responsive soybean GmNAC003 and GmNAC004 genes were included in the...
Microcystins (MCs) produced by cyanobacteria and their continuing "blooms" are a worldwide problem owing to the toxicity of microcystin-LR (MC-LR) to plants and animals. In the present study, we investigated membrane transport of MC-LR and its toxic effects on zebrafish embryos using fragmentation of embryos, scanning electron microscope (SEM), fluorescence microscopy, and toxic exposure tests....
