The results of these simulations revealed that both RM-532-105 (1) and FCO-586-119 (5) can compete for the cofactor-binding site displaying better binding energy than NADP+.While the positive effects of exercise on frailty are well documented, the effect of exercise on quality of life (QoL) and activities of daily living (ADL) in frail older adults remains less certain. Pralsetinib Therefore, this paper aimed to systematically review the literature investigating the effect of exercise on QoL and ADL in this group. Embase, MEDLINE, CENTRAL, PEDro and Web of Science Core Collections were searched systematically using relevant MeSH terms. The inclusion criteria were controlled trial design, published in English, population included frail older adults, frailty measured quantitatively, interventions that included exercise, and QoL or ADL measurements (PROSPERO CRD42018106173). After screening, 15 studies were eligible for inclusion in the qualitative synthesis (total n 2467; mean age range 70-85 years). There was a positive effect on QoL or ADL measures in 10 out of the 15 studies. QoL and ADLs only improved in studies that also reported improved physical outcomes. These results reflect the multi-factoral nature of frailty and how physical capability and QoL are interlinked. Heterogeneity precluded formal meta-analysis. Future trials in frail older adults should focus on interventions that include exercise, measure physical outcomes and use consistent study design to enable meta-analysis to be conducted.Brain-derived neurotrophic factor (BDNF) is known to have neuroprotective effects on multiple neurovascular diseases especially poststroke recovery. On the other hand, BDNF reported to increase blood pressure (BP) which is one of the major risk factors for stroke onset. To clarify the conflicting effects on stroke onset, we examined the expression of endogenous BDNF in relation to stroke onset. In addition, we explored the effect of exogenous central BDNF against stroke onset and all-cause mortality as the primary endpoint and BP as the secondary object in hypertensive rats with high-salt diet. In experiment 1, male spontaneously hypertensive stroke-prone rats (SHRSP) were fed a 0.3% (n = 8) or an 8% (n = 22) sodium diet (Na) through 28 days. The SHRSP with 8% Na showed significant increase of stroke onset, all-cause mortality, upregulation of reactive astrocytes, and disruption of blood-brain barrier. BDNF in the rats with 8% Na was significantly upregulated and mainly expressed in reactive astrocytes, whereas phosphorylated tropomyosin-related kinase B did not change by the rich BDNF. link2 In experiment 2, male SHRSP were treated with continuous intracerebroventricular injection of 2.1 μg/day BDNF (n = 10) or the vehicle (Phosphate buffer saline; n = 10) and fed an 8% Na through 24 days. Exogenous central BDNF induced significant increase of BP and heart rate, and exhibited higher stroke onset and all-cause mortality compared with vehicle group. The present study demonstrated that endogenous BDNF were significantly produced in reactive astrocytes in relation to stroke onset regardless of neuroprotection. In addition, exogenous central BDNF increased BP which might be associated with sympathetic nerve activity and provided unfavorable effects on the prognosis of hypertensive rats. link3 As BDNF is still potentially a good candidate for the treatment of neurovascular diseases, we suggest that hypertensive patients need care for the elevation of BP in the clinical trials of BDNF.Trovafloxacin (TVX) is associated with idiosyncratic drug-induced liver injury (iDILI) and inflammation-mediated hepatotoxicity. However, the inflammatory stress-regulated mechanisms in iDILI remain unclear. Herein, we elucidated the novel role of tumor-necrosis factor alpha (TNFα), an inflammatory stress factor, in TVX-induced in vitro hepatotoxicity and synergistic toxicity. TVX specifically induced synergistic toxicity in HepG2 cells with TNFα, which inhibits autophagy. TVX-treated HepG2 cells induced protective autophagy by inhibiting the expression of mTOR signaling proteins, while ATG5 knockdown in HepG2 cells, responsible for the impairment of autophagy, enhanced TVX-induced toxicity due to the increase in cytochrome C release and JNK pathway activation. Interestingly, the expression of mTOR signal proteins, which were suppressed by TVX, disrupted the negative feedback of the PI3K/AKT pathway and TNFα rebounded p70S6K phosphorylation. Co-treatment with TVX and TNFα inhibited protective autophagy by maintaining p70S6K activity, which enhanced TVX-induced cytotoxicity. Phosphorylation of p70S6K was inhibited by siRNA knockdown and rapamycin to restore TNFα-inhibited autophagy, which prevented the synergistic effect on TVX-induced cytotoxicity. These results indicate that TVX activates protective autophagy in HepG2 cells exposed to toxicity and an imbalance in negative feedback regulation of autophagy by TNFα synergistically enhanced the toxicity. The finding from this study may contribute to a better understanding of the mechanisms underlying iDILI associated with inflammatory stress.Neonicotinoids, which act as agonists of the nicotinic acetylcholine receptors of insects, are widely used pesticides worldwide. Although epidemiological studies revealed that the detection amounts of neonicotinoids in urine are higher in the elderly population than other age-groups, there is no available information regarding the risks of neonicotinoids to older mammals. This study was aimed to investigate aging-related differences in the behavioral effects of the neonicotinoid pesticide clothianidin (CLO). We acutely administered a sub-NOAEL level (5 mg/kg) of CLO to adult (12-week-old) and aging (90-week-old) mice and conducted four behavioral tests focusing on the emotional behavior. In addition, we measured the concentrations of CLO and its metabolites in blood, brain and urine. There were age-related changes in most parameters in all behavioral tests, and CLO significantly decreased the locomotor activity in the open field test and elevated plus-maze test in the aging group, but not in the adult group. The concentrations of most CLO and its metabolites were significantly higher in the blood and brain and were slightly lower in the urine in the aging group compared to the adult group. These findings should contribute to our understanding of age-related differences in the adverse effects of neonicotinoids in mammals.In recent years, there has been a shift from extrapleural pneumonectomy (EPP) toward pleurectomy/decortication (P/D) as the preferred surgical technique. However, we occasionally encounter difficult cases wherein visceral pleurectomy requires conversion to EPP from P/D. We sought to clarify the preoperative risk factors and clinical outcomes associated with conversion to EPP. We compared and analyzed conversion to EPP and P/D between September 2012 and December 2019. Conversion to EPP was decided in case of diffuse tumor invasion to the pulmonary parenchyma or due to failure of decortication. Univariable regression analysis was performed to determine the association of preoperative variables with conversion to EPP. Survival was analyzed by the Kaplan-Meier method and log-rank test. Of the 181 patients who underwent intended P/D, 145 (80.1%) patients underwent P/D and 18 (9.9%) patients underwent conversion to EPP. The sum of 3-level pleural thickness (P less then 0.001), maximum of 3-level pleural thickness (P = 0.006), and clinical T stage (P less then 0.001) demonstrated association with conversion to EPP. Overall survival and progression-free survival were significantly worse in the conversion to EPP group (median overall survival, 29.2 months vs 57.0 months [P = 0.008]; median progression-free survival, 15.3 months vs 23.2 months [P = 0.005]. Our data show that approximately 1 of every 10 patients with P/D intention converted to EPP. Preoperative pleural thickness and clinical T stage may be risk factors associated with conversion to EPP. The survival rate of conversion to EPP was worse than that of P/D.David V valve-sparing root replacement (VSRR) and bio-Bentall (BB) are increasingly performed for aortic root aneurysms associated with a bicuspid aortic valve (BAV). However, durability remains a concern in both procedures. We compared the 10-year outcomes of VSRR vs BB for BAV-associated root aneurysms. A retrospective review identified 134 patients with a BAV-associated root aneurysm who underwent VSRR (n = 65) or BB (n = 69) from 2005 to 2019. Patients with aortic stenosis, endocarditis, previous aortic valve replacement, and emergent cases were excluded. Propensity-score matching was performed, resulting in 2 risk-adjusted groups (n = 40 per group). Median follow-up was 6.21 (1.43-8.28) years. The VSRR cohort was younger (46.0 years vs 56.0 years, P less then 0.001) and had a lower incidence of at least moderate aortic insufficiency (AI) (78.5% vs 92.8%, P = 0.02). The incidence of Marfan syndrome, aortic root diameter, and ascending aortic diameter were similar. In-hospital mortality was 1.5% (n = 1) and 1.4% (n = 1) for VSRR and BB, respectively. There was no difference between VSRR and BB in 10-year survival (98.3% [95% confidence interval (CI) 88.6-99.8%] vs 96.2% [95% CI 85.5-99.0%], P = 0.567) and aortic valve reintervention at 10 years (16.1% [95% CI 6.3-29.8%] vs 12.9% [95% CI 3.7-28.0%], P = 0.309). The most common reason for valve reintervention in both groups was AI. Survival and valve reintervention at 10 years were similar in the matched cohort. David V VSRR yields similar mid to long-term outcomes to BB for select patients with a BAV-associated aortic root aneurysm in regards to survival and reintervention rates. Further studies comparing longer term outcomes between root replacement techniques and native valve durability are needed.It has been well documented that the use of the left internal thoracic artery (LITA) to graft the left anterior descending (LAD) artery has a significant benefit in coronary artery bypass graft (CABG) surgery. However, what graft is the best as a second conduit to complement LITA-LAD anastomosis remains uncertain. We thus conducted a network meta-analysis of RCTs to compare graft patency of the radial artery (RA), the right internal thoracic artery (RITA), the right gastroepiploic artery (RGEA), conventional saphenous vein (C-SVG), and no-touch saphenous vein (NT-SVG) as a second conduit in CABG. MEDLINE and EMBASE were searched through August 31, 2020 to identify randomized controlled trials (RCTs) that investigated graft patency of a second conduit in CABG. From each study, we extracted the incidence rate ratios of the outcome. A total of 13 RCTs were identified, including 3728 patients and 2773 angiographic results. The graft failure rates were significantly lower in NT-SVG and RA compared to C-SVG and RGEA. There was no significant difference among the other comparisons. A sensitivity analysis restricting trials with ≥3 years angiographic follow-up time showed the graft failure rates were significantly lower in NT-SVG and RA compared to C-SVG and RGEA, and a sensitivity analysis restricting trials with ≥5 years angiographic follow-up time showed the graft failure rates were significantly lower in NT-SVG and RA compared to C-SVG. In a network meta-analysis of the updated outcomes from RCTs, NT-SVG and RA have better graft patency compared to C-SVG and RGEA.
