The infectious disease tuberculosis remains a serious global health issue and is responsible for nearly 1.8 million deaths every year. In our previous study, DFC-2 was confirmed to show anti-tubercular activity against drug-susceptible and drug-resistant strains of Mycobacterium tuberculosis. To support the safety-in-use of DFC-2 as an anti-tubercular drug, DFC-2 was tested via single- and 28-day repeated-dose oral toxicity study and mutagenicity assays. In the oral toxicity study, a single oral dose of DFC-2 at 2000 mg/kg did not produce deaths or abnormal lesions in the internal organs of rats...

Histories of early life stress (ELS) or social discrimination can reach levels of severity characterized as toxic to mental and physical health. Such toxic social stress during development has been linked to altered acute hypothalamic-pituitary-adrenal (HPA) response to social stress in adulthood. However, there are important individual differences in the size and direction of these effects. We explored developmental, genetic, epigenetic, and contextual sources of individual differences in the relationship between ELS, discrimination, and adult responses to acute social stress in a standard laboratory test...

The application of microbubble (MB)-assisted ultrasound (US) can combine the advantages of real-time imaging and targeted drug delivery. However, the drug loading capacity of MB is limited restricting its application in antitumor procedure. In contrast, nanoparticles (NPs) can carry drugs more efficiently, but adverse side effect induced by unspecific accumulation can not be ignored. Herein, we developed a dual-functionalized NP loaded MB to investigate its potential feasibility for tumor-targeted drug delivery...

OBJECTIVES: Chronic systemic low grade inflammation is associated with the age-related loss of muscle mass. Resistance exercise has been suggested to reduce or lower chronic systemic low grade inflammation. However, systemic chronic low-grade inflammation may adversely affect the adaptive response to exercise training. We investigated the effect of resistance exercise training on systemic chronic low-grade inflammation in older adults. In addition, we studied the association between systemic chronic low-grade inflammation and the adaptive response to exercise training...
