Olfactomedin1 (Olfm1) in fallopian tube may modulate tubal ectopic pregnancy in humans: evidence from Immunohistochemistry and an in vitro coculture model

Conference Theme: The Intersection Between Genetics, Genomics, and Reproductive BiologyOlfactomedins are secretary glycoprotein constituted in the extracellular matrix (ECM) of various cell types. Recent studies suggested that Olfm-1 is down-regulated during the window of implantation (WOI) in the human endometrium and up-regulated in pathological condition like endometriosis and recurrent spontaneous abortions. Ectopic pregnancy is a gynaecological emergency and fertility threatening phenomenon which occurs in 1-2% of normal pregnancies and shows an increasing trend. Yet, tubal ectopic pregnancy accounts for more than 98% of the cases ...postprintThe 43rd Annual Meeting of the Society for the Study of Preproduction (SSR), Milwaukee, WI., 30 July-3 August 2010.

Characterization of volatile organic compounds at a roadside environment in Hong Kong: An investigation of influences after air pollution control strategies

Vehicular emission is one of the important anthropogenic pollution sources for volatile organic compounds (VOCs). Four characterization campaigns were conducted at a representative urban roadside environment in Hong Kong between May 2011 and February 2012. Carbon monoxide (CO) and VOCs including methane (CH4), non-methane hydrocarbons (NMHCs), halocarbons, and alkyl nitrates were quantified. Both mixing ratios and compositions of the target VOCs show ignorable seasonal variations. Except CO, liquefied petroleum gas (LPG) tracers of propane, i-butane and n-butane are the three most abundant VOCs, which increased significantly as compared with the data measured at the same location in 2003. Meanwhile, the mixing ratios of diesel- and gasoline tracers such as ethyne, alkenes, aromatics, halogenated, and nitrated hydrocarbons decreased by at least of 37%. The application of advanced multivariate receptor modeling technique of positive matrix factorization (PMF) evidenced that the LPG fuel consumption is the largest pollution source, accounting for 60 ± 5% of the total quantified VOCs at the roadside location. The sum of ozone formation potential (OFP) for the target VOCs was 300.9 μg-O3 m-3, which was 47% lower than the value of 567.3 μg-O3 m-3 measured in 2003. The utilization of LPG as fuel in public transport (i.e., taxis and mini-buses) contributed 51% of the sum of OFP, significantly higher than the contributions from gasoline- (16%) and diesel-fueled (12%) engine emissions. Our results demonstrated the effectiveness of the switch from diesel to LPG-fueled engine for taxis and mini-buses implemented by the Hong Kong Special Administrative Region (HKSAR) Government between the recent ten years, in additional to the execution of substitution to LPG-fueled engine and restrictions of the vehicular emissions in compliance with the updated European emission standards

Bortezomib combines with suberoylanilide hydroxamic acid (SAHA) to synergistically induce caspase-dependent apoptosis and blocks SAHA's activation of EBV lytic cycle in nasopharyngeal carcinoma

Poster Session 1 - Vaccines and Anti-Viral Therapeutics: no. 3.13Histone deacetylase inhibitor, suberoylanilide hydroxamic acid (SAHA), could induce Epstein-Barr virus (EBV) lytic cycle and apoptosis in EBV-positive nasopharyngeal carcinoma (NPC) cells. In this study, we investigated the effects of combining a proteasome inhibitor, bortezomib, with SAHA in the treatment of NPC cells. Synergistic killing of a panel of EBV-positive NPC cells upon treatment with various combinations of bortezomib (0, 7.5, 15, 30, 60 and 120 nM) and SAHA (0, 0.625, 1.25, 2.5, 5 and 10 uM) was demonstrated by MTT assay and isobologram analysis. The synergistic killing was due to apoptosis as demonstrated by markedly increased sub-G1, annexin V-positive and TUNEL-positive cell populations. Strong proteolytic cleavage of PARP, caspase-3, -7 and -9 and increased reactive oxygen species …postprin
