Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

[Q]: Evodiamine is one of active alkaloids isolated from the traditional Chinese medicine Evodia rutaecarpa Bentham and has various pharmacological properties. In this study, we investigated its effects on the migration, invasion, and associated mechanism in human nasopharyngeal carcinoma (NPC) cells.', 'Cell viability was determined by MTT assay after evodiamine treatment. Wound-healing assay and Boyden transwell system were used to evaluate the inhibitory effects of evodiamine on cell migration and invasion. MMP-2/9 activity was determined using commercial detection kits. The levels of associated proteins involved in the regulation of cell migration and invasion were analyzed by Western blotting.', 'Evodiamine effectively inhibited the migration and invasion of HONE1 and CNE1 cells, and hardly affected cell proliferation, but significantly suppressed cell adhesion activity in vitro. Additionally, evodiamine treatment significantly decreased mRNA and protein levels of MMP-2 and its activity in the NPC cells, but had little effects on MMP-9 mRNA and protein levels and its activity. Further investigation revealed that evodiamine inhibited the translocation of NF-B p65, which involves the regulation of MMP-2 expression in cancer invasion. Additionally, evodiamine treatment did not significantly affect the protein levels of JNK, p38, Akt, and their phosphorylated forms and ERK1/2, but strongly attenuated ERK1/2 phosphorylation level, which at least partly accounts for the signal pathway of evodiamine-inhibited migration and invasion of NPC cells.

[Q]: An effective HIV vaccine will likely require induction of both mucosal and systemic cellular and humoral immune responses. We investigated whether intramuscular (IM) delivery of electroporated plasmid DNA vaccine and simultaneous protein vaccinations by intranasal (IN) and IM routes could be combined to induce mucosal and systemic cellular and humoral immune responses to a model HIV-1 CN54 gp140 antigen in mice.', 'Co-immunisation of DNA with intranasal protein successfully elicited both serum and vaginal IgG and IgA responses, whereas DNA and IM protein co-delivery did not induce systemic or mucosal IgA responses. Cellular IFN responses were preserved in co-immunisation protocols compared to protein-only vaccination groups. The addition of DNA to IN protein vaccination reduced the strong Th2 bias observed with IN protein vaccination alone. Luminex analysis also revealed that co-immunisation with DNA and IN protein induced expression of cytokines that promote B-cell function, generation of TFH cells and CCR5 ligands that can reduce HIV infectivity.

[Q]: Mitochondrial dysfunction has been well documented in age related disorders like Alzheimer's disease. Alterations in mitochondrial membrane potential lead to neuronal death by excessive generation of free radicals, inflammatory cytokines, and excitotoxins. Intracerebroventricular (ICV) streptozotocin (STZ) induced-cognitive impairment has been widely used as an experimental model of Alzheimer's disease. Naringin is a potent antioxidant, which can cross the blood brain barrier protecting brain tissue and modulating brain chemistry.", 'The present study was designed to evaluate the effect of naringin, in ICV STZ-induced mitochondrial dysfunction and memory loss in rats.', 'Streptozotocin (3mg/kg, ICV) was injected bilaterally in two divided doses on first and third day followed by treatment with different doses of naringin (50, 100 and 200mg/kg; p.o.) for twenty one days. Behavioral alterations were monitored using Morris water maze paradigm and elevated plus maze test. Animals were sacrificed to evaluate various biochemical and mitochondrial parameters in brain. Rivastigmine was used as a standard drug.', 'ICV-STZ administration produced significant cognitive deficits as assessed by both Morris water maze and elevated plus maze task which is accompanied by significantly enhanced oxidative-nitrosative stress, altered acetylcholinesterase and mitochondrial enzyme activities in cerebral cortex and hippocampus of rats brain along with significantly increased brain TNF- and IL-1 levels. Chronic treatment with naringin dose dependently restored cognitive deficits in ICV-STZ rat along with mitigation of mitochondrial dysfunction mediated oxido-nitrosative stress and cytokine release.
