Abstrakt. Jedním ze základních přístupů při kategorizaci textu je reprezentovat dokumenty jednotlivými slovy. Tento přístup je označován jako bag-of-words nebo také single words-based. Nicméně dalším obohacením této reprezentace je možné dosáhnout zlepšení výsledků klasifikace. V této práci jsme zaměřili svou pozornost na porovnání přínosu bigramů a 2-itemsetů, o které je rozšířen klasický bag-...

The structure of HIV protease (HIV Pr) bound to JE-2147 (also named AG1776 or KNI-764) is determined here to 1.09 A resolution. This highest-resolution structure for HIV Pr allows refinement of anisotropic displacement parameters (ADPs) for all atoms. Clustering based on the directional information in ADPs defines two sets of subdomains such that within each set, subdomains undergo similar anis...

BACKGROUND Japanese encephalitis (JE) virus is the leading cause of vaccine-preventable encephalitis in Asia. Although the risk for acquiring JE for most travelers to Asia is low, it varies based on the destination, season, trip duration, and activities. METHODS We present case reports of three US adults who were infected with JE virus while traveling or residing in Asia. RESULTS Among the ...

PURPOSE To determine the usefulness of single-photon emission CT (SPECT) in the diagnosis of acute Japanese encephalitis (JE). METHODS We examined 10 patients (six men and four women; mean age, 69 years) with viral encephalitis. We divided the cases into two groups: the JE group (n = 4) and the non-JE group (n = 6; two with herpes simplex encephalitis and four with encephalitis of unknown ori...

BACKGROUND A mass Japanese encephalitis (JE) vaccination program targeting children was launched in Taiwan in 1968, and the number of pediatric JE cases substantially decreased thereafter. The aim of this study was to elucidate the long-term trend of JE incidence, and to investigate the age-specific seroprevalence of JE-neutralizing antibodies. METHODOLOGY/PRINCIPAL FINDINGS A total of 2,948 ...

BACKGROUND Japanese encephalitis virus (JEV) is an important cause of encephalitis in most of Asia, with high case fatality rates and often significant neurologic sequelae among survivors. The epidemiology of JE in the Philippines is not well defined. To support consideration of JE vaccine for introduction into the national schedule in the Philippines, we conducted a systematic literature revie...

BACKGROUND Japanese encephalitis (JE) vaccination is the most effective measure for preventing JE disease. The live attenuated JE vaccine, which has shown good efficacy and safety, has been widely used in China. CASE PRESENTATIONS We report four laboratory-confirmed JE cases detected in JE-endemic areas during the JE virus (JEV) transmission season, who all received a first dose of live atten...

Akutni pankreatitis (AP) je ozbiljna bolest, dei nirana kao akutni upalni proces gušterače koji može dovesti do oštećenja okolnih tkiva i drugih organskih sustava. To je skup dinamičnih, lokalnih i sistemskih patoi zioloških promjena, nastalih iznenadnim prodorom litičkih pankreasnih enzima u žlijezdani parenhim. AP je upalni proces u kojem dolazi do autodigestije tkiva gušterače uzrokovane pre...

Hybridoma cells were produced by fusing P3X63Ag8.653 mouse myeloma cells with spleen cells from BALB/c mice immunized with Japanese encephalitis (JE) virus, Nakayama-RFVL strain. The resulting 26 clones produced hemagglutination inhibition antibodies against the homologous strain. The hemagglutination inhibition reactivity of each clone was tested against six flaviviruses: JE, Murray Valley enc...
