We report on the discovery of HAT-P-12b, a transiting extrasolar planet orbiting the moderately bright V ≈ 12.8 K4 dwarf GSC 03033-00706, with a period P = 3.2130598 ± 0.0000021 d, transit epoch Tc = 2454419.19556± 0.00020 (BJD) and transit duration 0.0974± 0.0006d. The host star has a mass of 0.73 ± 0.02M⊙, radius of 0.70 +0.02 −0.01R⊙, effective temperature 4650 ± 60K and metallicity [Fe/H ] ...

Jiaogulan (Gynostemma pentaphyllum; GP) contained a saponin glycoside which was related to ginseng saponin. The purpose of this study was to identify the main saponin in water extract GP compared to methanol and ethanol extract. The sample was prepared by alkaline cleavage, trimethylsilyl (TMS) derivatization and gas chromatographic-mass spectrometric (GC-MS) analysis comparison with standard g...

INTRODUCTION Severity of mucosal inflammation is shown to be associated with Barrett's esophagus (BE) development in animals. It has therefore been postulated that a strong pro-inflammatory host response predisposes to BE. AIM To determine the impact of cytokine gene polymorphisms on the development of BE. METHODS The multiplex SNaPshot method was used to determine interleukin (IL)-12B (A+1...

In this review, we have summarized our work using combined complex statistical genetics, bioinformatics, and functional genomics to determine the genetic basis of the age-related thymic involution in C57BL/6J X DBA/2J recombinant inbred mice and the parental B6 and D2 mice. We have shown that these mice provided a valuable genetic model that can permit resampling of thymuses from different aged...

Micrococcus sp. strain 12B was isolated by enriching for growth with dibutylphthalate as the sole carbon and energy source. A pathway for the metabolism of dibutylphthalate and phthalate by micrococcus sp. strain 12B is proposed: dibutylphthalate leads to monobutylphthalate leads to phthalate leads to 3,4-dihydro-3,4-dihydroxyphthalate leads to 3,4-dihydroxyphthalate leads to protocatechuate (3...

In a meta-analysis of 10 studies, the BACTEC 960/MGIT and BACTEC 460 systems showed a sensitivity and specificity in detecting mycobacteria (1,381 strains from 14,745 clinical specimens) of 81.5 and 99.6% and 85.8 and 99.9%, respectively. Combined with solid media, the sensitivity of the two systems increased to 87.7 and 89.7%, respectively.

Inheritance of polymorphisms in the interleukin (IL)-10 promoter and IL-12B genes, which influence cytokine production and activities, may define the balance in T helper response in infection and autoimmune diseases. In the present study, we investigated the distribution of the IL-10 promoter and IL-12B gene polymorphisms in a multiethnic Malaysian population. Overall, our findings suggest that...

Using two different liquid media and one conventional solid medium, a total of 57 mycobacterial isolates (Mycobacterium tuberculosis, n = 55; nontuberculous mycobacteria, n = 2) were recovered from 377 clinical specimens. The rates of recovery of M. tuberculosis were 96. 4% with the BACTEC MGIT 960 liquid medium, 92.7% with BACTEC 12B liquid medium, and 81.8% with the Löwenstein-Jensen (LJ) med...
