We report that Esf1p (Ydr365cp), an essential, evolutionarily conserved nucleolar protein, is required for the biogenesis of 18S rRNA in Saccharomyces cerevisiae. Depletion of Esf1p resulted in delayed processing of 35S precursor and a striking loss of 18S rRNA. Esf1p physically associated with ribosomal proteins and proteins involved in 18S rRNA biogenesis. Consistent with its role in 18S rRNA...

Current trends in attacking strategies and increases external workload have led to a need for fast well-conditioned athletes modern soccer. More recently, progressions speed, coordination, power endurance were found over decade elite Austrian youth players. However, possible confounders such as relative age, maturation, learning effects, academy philosophy may influenced these changes. The pres...

This study examined (1) the distances and speeds covered during match play for U11 to U16 English Premier League Academy players, (2) the differences in match performance between retained and released players and (3) the effect of calculating speed zones in different ways when analysing match performance. Eighty-one academy outfield players (10-16 years old), competing in 11-a-side matches, wer...

Kuding tea (Ilex kudingcha C.J. Tseng) is drunk widely in China. The in vitro anticancer effects of Kuding tea were evaluated in TCA8113 human tongue carcinoma cells using a 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyltetrazolium bromide (MTT) assay. At a concentration of 200 μg/ml, Kuding tea exhibited an inhibitory effect of 75% in TCA8113 cells, which was higher than that observed at concentrat...

The relative age effect (RAE) and its relationships with maturation, anthropometry, and physical performance characteristics were examined across a representative sample of English youth soccer development programmes. Birth dates of 1,212 players, chronologically age-grouped (i.e., U9's-U18's), representing 17 professional clubs (i.e., playing in Leagues 1 & 2) were obtained and categorised int...

We have shown previously that groups of U14 snoRNA genes are clustered with other, novel snoRNAs in maize. These genes are transcribed polycistronically from an upstream promoter to give a precursor snoRNA, which is processed by a splicing-independent mechanism. The clusters contain both box C/D snoRNAs, thought to guide rRNA O-ribose methylations, and the first plant box H/ACA snoRNA so far id...

PURPOSE To explore the antitumor effect of prescription consisting of Vitamin C (Vc) and Baicalin (PVB). METHODS To explore the antitumor effect of PVB, using U14 cervical tumor-bearing mice model was used and the drugs were administrated through the gavages. Spectrophotometry was used to determine the content of superoxide dismutase (SOD), malondialdehyde (MDA) and cytokines IL-2, Il-4 and I...
