Tuberculosis remains second only to HIV/AIDS as the leading cause of mortality worldwide due to a single infectious agent. Despite chemotherapy, the global tuberculosis epidemic has intensified because of HIV co-infection, the lack of an effective vaccine and the emergence of multi-drug-resistant bacteria. Alternative host-directed strategies could be(More)
BACKGROUND Coronary heart disease (CHD) mortality is rising in many developing countries. We examined how much of the increase in CHD mortality in Beijing, China, between 1984 and 1999 could be attributed to changes in major cardiovascular risk factors and assessed the impact of medical and surgical treatments. METHODS AND RESULTS A validated, cell-based(More)
To effectively realize the image feature matching for geomorphic reverse measurement and rebuilding, a new matching scheme is presented, where the SIFT method are adopted to implement initial geomorphic image matching by going through five stages: scale-space construction, scale-space extrema detection, orientation assignment, keypoint descriptor and(More)
BACKGROUND We studied the operation rate for secondary displacement in Garden type 1 femoral neck fracture when treated primarily conservatively. METHODS We reviewed the records of 115 patients with Garden type 1 femoral neck fractures primarily treated conservatively. RESULTS Operation for secondary displacement was required in 48 cases (41%); the(More)
Ammonia-oxidising archaea (AOA) are increasingly recognised as the primary mediators of soil ammonia oxidation, particularly in acidic soils. To explore the niche segregation of AOA and ammonia-oxidising bacteria (AOB) and the potential effect of this segregation on nitrification rates and the nitrogen cycle in Chinese agricultural soils, AOA and AOB amoA(More)
An LC-MS/MS method was developed for the simultaneous determination of chlorogenic acid, forsythiaside A and baicalin, three major ingredients in Shuang-huang-lian preparations, in rat plasma. Following extraction by methanol-ethyl acetate-trifluoroacetic acid (49:49:2, v/v/v), the extracted analytes were separated on a reverse phase C12 column using a(More)
Abnormalities in amygdala activity have been implicated in adolescents and older adults with major depressive disorder (MDD), but few studies have focused on young adults with early-onset MDD. In this study, we measured amygdala activity in 27 young adults with early-onset MDD and 25 healthy controls (HC) using functional magnetic resonance imaging (fMRI)(More)
Resistance to cisplatin is the main reason for treatment failure in ovarian cancer. Apoptosis is the main mechanism of action of most cancer chemotherapeutic agents. The apoptosis-associated proteins expressed in cisplatin-sensitive (A2780, COC1) and -resistant (A2780/DDP, COC1/DDP) ovarian cancer cell lines, as well as their effects on caspase-3 activity(More)
Mastitis comprises an inflammation of the mammary gland, which is almost always linked with bacterial infection. The treatment of mastitis concerns antimicrobial substances, but not very successful. On the other hand, anti-inflammatory therapy with Chinese traditional medicine becomes an effective way for treating mastitis. Magnolol is a polyphenolic(More)
