Question: Context: Triptolide (TPT), a component of the Chinese herb Triptergium wilfordii, has potent immunosuppressive and anti-inflammatory activity and is used clinically in recipients of kidney transplantation.', 'This work aimed to investigate the effect of TPT on the differentiation of regulatory T lymphocytes (Tregs) from CD4+ cells in rats.', 'MACS-purified rat CD4+ cells were costimulated with anti-CD3 and anti-CD28 in the presence of TGF-beta to induce the expression of FoxP3, which was detected by flow cytometry. TPT and cyclosporine A (CsA) were separately added into the cultures to observe the effect on the expression of FoxP3. Kidney transplantation was performed in rats that either received no treatment or were treated with TPT after transplantation.', 'TPT treatment enhanced the expression of FoxP3 in CD4+ cells, whereas CsA inhibited the FoxP3 expression. In the rat kidney transplantation model, the recipient rats treated with TPT survived longer than the control rats (18-19.83 vs 6.83 days, P<0.05). Meanwhile, the FoxP3+ T cells in the spleens of treated rats were higher than those from the untreated rats (12.4% vs 4.7%, P<0.05).\Question: Does triptolide promote generation of FoxP3+ T regulatory cells in rats?

Answer: These data suggest that TPT may promote the differentiation of CD4+ cells to FoxP3+ Tregs. This would be at least one of the pathways responsible for the immunosuppressive activity of TPT.


Question: Context: Dynamic pelvic magnetic resonance imaging (DP-MRI) offers a comprehensive evaluation of pelvic organ structure in addition to functional information regarding evacuation. Opportunity to apply this technology can be limited due to regional lack of availability. Ideally, clues from standard anorectal testing could predict abnormalities on DP-MRI, leading to its efficient use. The aim of this study is to determine whether high-resolution anorectal manometry (HR-ARM) correlates with findings on DP-MRI.', "This is a retrospective study of HR-ARM performed on patients with constipation who also underwent DP-MRI. Studies were reviewed for significant findings including posterior pelvic organ prolapse, rectocele\u2009>\u20093\u2009cm, rectal intussusception, and anorectal angle. Statistical analysis was performed using Pearson's correlation coefficient, Student's t-test, and Fisher's exact test.", 'Twenty-three patients undergoing HR-ARM (age range 25-78) also underwent DP-MRI. All were female; 76% were Caucasian. Twenty had significant structural findings: small pelvic prolapse (n\u2009=\u20092), moderate pelvic prolapse (n\u2009=\u200910), large pelvic prolapse (n\u2009=\u20099), rectocele (n\u2009=\u20098), or rectal intussusception (n\u2009=\u20093). Only intrarectal pressure on HR-ARM weakly correlated with size of rectocele (r\u2009=\u20090.46; P\u2009=\u20090.03) and degree of pelvic organ prolapse (r\u2009=\u20090.48; P\u2009=\u20090.02). The remainder of the HR-ARM parameters did not significantly correlate with DP-MRI findings. Patients with dyssynergy were not more likely to have rectoceles\u2009>\u20093\u2009cm (44.4% versus 35.7%; P\u2009=\u20090.5) or large prolapses (44.4% versus 50%, P\u2009=\u20091.0), compared with those without dyssynergy, on HR-ARM.\Question: Are high-resolution anorectal manometry and dynamic pelvic magnetic resonance imaging complementary technologies?

Answer: We were unable to find a correlation between HR-ARM findings and structural pelvic defects on DP-MRI. Therefore, these two technologies provide complementary information in the evaluation of defecatory dysfunction.


Question: Context: Aging and obesity are associated with elevated pro-inflammatory cytokines such as monocyte chemoattractant protein (MCP)-1 and tumor necrosis factor (TNF)α, which are linked to insulin resistance. Anti-inflammatory agents have marginal effect in improving insulin resistance. Hence, agents are needed to improve glycemic control despite the inflammation. Ad36, a human adenovirus, increases TNFα and MCP1 mRNA in adipose tissue, yet improves glycemic control in mice. Ad36 via its E4orf1 gene, up-regulates AKT/glucose transporter (Glut)-4 signaling to enhance cellular glucose uptake.', 'Directly test a role of Ad36, or E4orf1 in enhancing cellular glucose uptake in presence of inflammatory cytokines.', 'Experiment 1: 3T3-L1 preadipocytes were treated with 0, 10 or 100\xa0ng/mL lipopolysaccharides (LPS), and infected with 0 or 5 plaque forming units (PFU) of Ad36/cell. 3T3-L1 cells that stably and inducibly express E4orf1 or a null vector (pTRE-E4orf1 or pTRE-null cells), were similarly treated with LPS and then with doxycycline, to induce E4orf1. Experiment 2: 3T3L1 preadipocytes were treated with 25\xa0nM MCP1 or 20\xa0nM TNFα for 16\xa0h, followed by infection with 0 or 5\xa0PFU of Ad36/cell. Experiment 3: pTRE-E4orf1 or -null cells were similarly treated with MCP1 or TNFα followed by doxycycline to induce E4orf1. Cellular glucose uptake and cellular signaling were determined 72\xa0h post-Ad36 infection or E4orf1-induction, in continued presence of MCP1 or TNFα.', 'In 3T3-L1 preadipocytes, Ad36, but not E4orf1, increased MCP1 and TNFα mRNA, in presence of LPS stimulation. Ad36 or E4orf1 up-regulated AKT-phosphorylation and Glut4 and increased glucose uptake (P\xa0<\xa00.05) in the presence of MCP1 or TNFα.\Question: Do human adenovirus Ad36 and its E4orf1 gene enhance cellular glucose uptake even in the presence of inflammatory cytokines?

Answer:
Unlike Ad36, E4orf1 does not appear to stimulate inflammatory response. Ad36 and E4orf1 both enhance cellular glucose uptake even in presence of inflammation. Further research is needed to harness this novel and beneficial property of E4orf1 to improve hyperglycemia despite chronic inflammation that is commonly present in aging and obesity.
