Twelve strains representing five novel yeast species were isolated from natural samples distributed in mountain areas in Taiwan during 2007 and 2009. Sequence analysis of the D1/D2 domain of the large subunit (LSU) rRNA gene revealed that these species are members of the Cyberlindnera clade. These five new species have a greater than 1% difference from(More)
A novel yeast species, Lachancea dasiensis sp. nov., is proposed in this paper based on two strains isolated from leaves and one strain from soil in Taiwan. The strains produce one or two spherical ascospores in each ascus, preceded by conjugation of individual cells. Genus assignment and distinction of the species from other recognized species of Lachancea(More)
A new yeast species, Kazachstania wufongensis, is proposed in this paper based on six strains isolated from soil in Taiwan. The species may produce one to four ellipsoidal ascospores in each ascus, directly transformed from diploid cells. Genus assignment and distinction of the species from other recognized species of Kazachstania is based on morphological(More)
Two novel yeast species, Asterotremella meifongana sp. nov. and Asterotremella nantouana sp. nov., belonging to Asterotremellaceae within the Trichosporonales, are proposed to accommodate five strains isolated from Taiwanese samples of soil and basidiocarps during 2006-2007. Sequence analysis of the D1/D2 domains of the large subunit rRNA gene revealed that(More)
Although hepatitis B virus (HBV) has been established to cause hepatocellular carcinoma (HCC), the exact mechanism remains to be clarified. Type II ground glass hepatocytes (GGHs) harbouring the HBV pre-S2 mutant large surface protein (LHBS) have been recognized as a morphologically distinct hallmark of HCC in the advanced stages of chronic HBV infection.(More)
In this paper we propose two public key BE schemes that have efficient complexity measures. The first scheme, called the PBE-PI scheme, has O(r) header size, O(1) public keys and O(log N) private keys per user, where r is the number of revoked users. This is the first public key BE scheme that has both public and private keys under O(log N) while the header(More)
Elevated levels of antibodies against Epstein-Barr virus (EBV) and the presence of viral DNA in plasma are reliable biomarkers for the diagnosis of nasopharyngeal carcinoma (NPC) in high-prevalence areas, such as South-East Asia. The presence of these viral markers in the circulation suggests that a minimal level of virus reactivation may have occurred in(More)
