The mechanisms that enable the hippocampal network to express the appropriate spatial representation for a particular circumstance are not well understood. Previous studies suggest that the medial entorhinal cortex (MEC) may have a role in reproducibly selecting the hippocampal representation of an environment. To examine how ongoing MEC activity is continually integrated by the hippocampus, we...

OBJECTIVE To compare risk factors, treatment, and outcomes in patients with stage I/II mucinous endometrial cancer (MEC) relative to those of patients with endometrioid endometrial cancer (EEC). STUDY DESIGN We conducted a case-control study of patients with MEC and EEC. Patients with stage IA, IB, or II MEC treated at the 2 institutions between 01/01/1996 and 01/01/2007 were identified. Each...

The process by which mechanical stimuli are converted into cellular responses is poorly understood, in part because key molecules in this mode of signal transduction, the mechanically gated ion channels, have eluded cloning efforts. The Caenorhabditis elegans mec-4 gene encodes a subunit of a candidate mechanosensitive ion channel that plays a critical role in touch reception. Comparative seque...

MOTIVATION Haplotype reconstruction based on aligned single nucleotide polymorphism (SNP) fragments is to infer a pair of haplotypes from localized polymorphism data gathered through short genome fragment assembly. An important computational model of this problem is the minimum error correction (MEC) model, which has been mentioned in several literatures. The model retrieves a pair of haplotype...

Neglected agricultural products (NAPs) are defined as discarded material in agricultural production. Corn cobs are a major waste of agriculture maize. Here, a methanolic extract from corn cobs (MEC) was obtained. MEC contains phenolic compounds, protein, carbohydrates (1.4:0.001:0.001). We evaluated the in vitro and in vivo antioxidant potential of MEC. Furthermore, its antiproliferative proper...

Earlier work showed that the Caenorhabditis elegans gene mec-8 encodes a regulator of alternative RNA splicing and that mec-8 null mutants have defects in sensory neurons and body muscle attachment but are generally viable and fertile. We have used a genetic screen to identify five mutations in four genes, sym-1-sym-4, that are synthetically lethal with mec-8 loss-of-function mutations. The phe...

We have used representational difference analysis (RDA) applied to cDNA to isolate transcripts regulated by MEC-3, a transcription factor needed for the differentiation of the six touch receptor neurons in Caenorhabditis elegans. Six percent of 595 cDNAs isolated by cDNA RDA were mec-3-dependent. These cDNAs represented mRNA from two previously known genes, mec-18 and mec-7, and one new gene, m...

The medial entorhinal cortex (MEC) and the adjacent parasubiculum are known for their elaborate spatial discharges (grid cells, border cells, etc.) and the precessing of spikes relative to the local field potential. We know little, however, about how spatio-temporal firing patterns map onto cell types. We find that cell type is a major determinant of spatio-temporal discharge properties. Parasu...

Supplementary Figures and Legends Figure S1 Time-course analysis of mec-4(d)-induced degeneration in mec-4(d) animals and in double mutants combining mutations in mec-4 and the endocytic genes snt-1 and unc-57 or the kinesin genes unc-116 and unc-104. The number of touch receptor neuron corpses at the indicated developmental stage, per 100 mec-4(d) animals is shown. Error bars denote S.E.M. val...

Interactions between the medial entorhinal cortex (MEC), presubiculum (PrS), and parasubiculum (PaS), all essential components of the hippocampalparahippocampal navigational system, are still poorly understood. The PrS and PaS are credited to provide directional information to MEC. Efferents from PrS and PaS show a laminar specific terminal distribution in MEC superficial layers, where they als...
