[EX Q]: To test the hypothesis that hyporesponsiveness to ghrelin due to reduced growth hormone (GH) contributes to the aging-related hyperinflammatory state in sepsis.', 'Sepsis and septic shock are a serious problem, particularly in the geriatric population. Ghrelin is an endogenous ligand for the GH secretagogue receptor 1a (GHSR1a, ie, ghrelin receptor). The decline in GH with age is directly associated with many adverse changes that occur with aging. However, the role of GH, ghrelin, and GHSR1a in the age-associated vulnerability to sepsis remains unknown.', 'Male Fischer 344 rats (young: 3 months; aged: 24 months) were used. Plasma GH levels, ghrelin receptor expression, and neuronal activity in the parasympathostimulatory nuclei of the brain stem in normal young and aged animals were measured. Endotoxemia was induced by intravenous injection of lipopolysaccharide (LPS, 15 mg/kg BW).', 'While LPS-induced release of proinflammatory cytokines from macrophages isolated from aged rats decreased, LPS injection resulted in an in vivo hyperinflammatory state. GH levels were lower in aged rats, which was associated with lower expression of GHSR1a in the dorsal vagal complex and a decrease in parasympathostimulatory neuronal activity. GHSR1a antagonist elevated LPS-induced cytokine release in young rats. GH increased GHSR-1a expression in the dorsal vagal complex in aged rats. Coadministration of ghrelin and GH, but not ghrelin alone or GH alone, markedly reduced cytokine levels and organ injury after endotoxemia in aged rats, which was associated with significantly elevated parasympathostimulatory neuronal activity.

[EX Q]: FoxO transcription factors have been reported to play pivotal roles in tumorigenesis and drug resistance. The mechanisms underlying the tumor suppression function of FoxOs in human cancers remain largely unknown. Aberrant expression and activation of Nrf2 often correlate with chemoresistance and poor prognosis. Here, we report that FoxO3 directs the basal transcription of Kelch-like ECH-associated protein 1 (Keap1), an adaptor protein that bridges Nrf2 to Cul3 for degradation. FoxO3 depletion resulted in Keap1 down-regulation, thereby activating Nrf2 signaling. We further demonstrated that inhibition of the FoxO3-Keap1 axis accounts for Nrf2 induction and activation induced by constitutively active AKT signaling or tumor necrosis factor α treatment. Unlike previous findings, FoxO3 silencing led to decreased reactive oxygen species production, therefore protecting cells from oxidative stress-induced killing in an Nrf2-dependent manner. Importantly, FoxO3 deficiency strongly potentiated tumor formation in nude mice and rendered cholangiocarcinoma xenografts resistant to cisplatin-induced cell death by activating Nrf2. Additionally, we found that clinical cholangiocarcinoma samples displayed FoxO3-Keap1 down-regulation and Nrf2 hyperactivation, underscoring the essential roles of these proteins in cholangiocarcinoma development.

[EX Q]: Current approaches for the treatment of gingival exposure are often time- and cost-consuming and/or rather invasive. We previously observed a strong correlation between the presence of gingival excess and midfacial depression and here propose an easy 1-step correction technique as a new strategy to improve gingival exposure.', 'From February 2004 to December 2012, 42 patients with gingival exposure associated with different degrees of midfacial depression, defined by Frankfort horizontal plane-labrale superius-subspinale angle and sella-nasion-A point angle, were treated by implantation of an inverted m-shaped expanded polytetrafluoroethylene at the base of the piriform aperture in a subperiosteal location. Patient pictures were taken preoperatively and postoperatively to assess gingival exposure at rest and fullest smile, as well as measurements of upper lip length, nasolabial angle, and facial convexity angle. A postoperative patient satisfaction survey was performed.', 'The average maximum gingival exposure was 5.52 ± 1.64 mm preoperatively and significantly decreased to 1.79 ± 0.67 mm at 6 months after surgery (P < 0.05) along with a significantly improved nasolabial angle from initially 85.3° ± 6.21° to 95.2° ± 7.1° (P < 0.05). The majority of patients (90.5%) rated their postoperative outcome as highly improved and improved. Temporary discomfort involving upper lip numbness, foreign body sensation, and stiff smiling expression was complained at 1 month postoperatively and gradually returned to normal after 3 months. No late recurrence or other complications were seen in any of the patients.
