Here, we characterize a new K(+) channel-kinase complex that operates in the metazoan Caenorhabditis elegans to control learning behaviour. This channel is composed of a pore-forming subunit, dubbed KHT-1 (73% homology to human Kv3.1), and the accessory subunit MPS-1, which shows kinase activity. Genetic, biochemical and electrophysiological evidence show that KHT-1 and MPS-1 form a complex in ...

background and aim: basal cell carcinoma (bcc) is the most common skin neoplasm and the most common type of cancer. since the incidence of injury is taken into consideration in the pathologic diagnosis, the study of clinical and microscopic views of bcc is of particular importance. the present study aimed at determining the frequency of clinical and microscopic views of bcc in a 10-year period ...

Several studies have associated mutations in genes encoding potassium channels and accessory subunits involved in cardiac repolarization with increased susceptibility of atrial fibrillation (AF). Recently, the Krüppel-like factor 15 (Klf15) was found to transcriptionally control rhythmic expression of KChIP2, a critical subunit required for generating the transient outward potassium current (It...

In this paper we propose a novel detail-enhancing exposure fusion approach using nonlinear translation-variant filter (NTF). With the captured Standard Dynamic Range (SDR) images under different exposure settings, first the fine details are extracted based on guided filter. Next, the base layers (i.e., images obtained from NTF) across all input images are fused using multiresolution pyramid. Ex...

Kuru provides our principal experience of an epidemic human prion disease and primarily affected the Fore linguistic group of the Eastern Highlands of Papua New Guinea. Kuru was transmitted by the practice of consuming dead relatives as a mark of respect and mourning (transumption). To date, detailed information of the prion strain type propagated in kuru has been lacking. Here, we directly com...

Variant Creutzfeldt-Jakob disease (vCJD) was first described in the United Kingdom in 1996 and is thought to have been transmitted from cattle infected with bovine spongiform encephalopathy probably via the food chain. Thus far just over 100 definite or probable clinical cases have been described, though the number of people currently infected and the eventual size and geographic distribution o...

Manganese peroxidase (MnP) is a heme-containing enzyme produced by white-rot fungi and is part of the extracellular lignin degrading system in these organisms. MnP is unique among Mn binding enzymes in its ability to bind and oxidize Mn(II) and efficiently release Mn(III). Initial site-directed mutagenesis studies identified the residues E35, E39, and D179 as the Mn binding ligands. However, an...

Background The physicians often confuse the early symptoms of Frontotemporal dementia (FTD) with Alzheimer dementia (AD), leading to misdiagnosis. There are some cognitive tests to discriminate between AD and behavioral variant FTD (bvFTD), and the INECO Frontal Screening (IFS) is a promising test for this purpose. Objective To assess the performance of the IFS to differentiate patients with ...

BACKGROUND The determination of the form of prion disease and early diagnosis are important for prognostic, public health, and epidemiologic reasons. OBJECTIVE To describe a patient with sporadic Creutzfeldt-Jakob disease (sCJD) who had a clinical history and initial electroencephalogram and magnetic resonance imaging findings consistent with variant CJD (vCJD). RESULTS Results of a repeate...
