Abstract
More than 500 million people suffer from allergic rhinitis (AR) in the world. Current treatments include oral antihistamines and intranasal corticosteroids; however, they often cause side effects and are unsuitable for long-term exposure. Natural products could work as a feasible alternative, and this study aimed to review the efficacies and mechanisms of natural substances in AR therapies by examining previous literature. Fifty-seven studies were collected and classified into plants, fungi, and minerals decoction; clinical trials were organized separately. The majority of the natural products showed their efficacies by two mechanisms: anti-inflammation regulating diverse mediators and anti-oxidation controlling the activity of nuclear factor kappa-light-chain-enhancer of activated B cells (NFκB) pathway stimulated by reactive oxygen species (ROS). The main AR factors modified by natural products included interleukin (IL)-4, IL-5, IL-13, interferon-gamma (IFN-γ), tumor necrosis factor-α (TNF-α), cyclooxygenase 2 (COX-2), and phospho-ERK1/2 (p-ERK1/2). Although further studies are required to verify their efficacies and safeties, natural products can significantly contribute to the treatment of AR.

Abstract
Abstract
Introduction
Exercise training (ET) improves endothelial function and arterial stiffness in patients with cardiovascular disease. However, whether ET improves endothelial function and arterial stiffness in patients with atrial fibrillation (AF) is unclear. If it does, for how long the effects are sustained remains to be determined.
Methods
In a prospective study, 58 patients with AF (age, 62 ± 7 years) were randomized into an ET group for 12 months (CT, n = 13), a group with 6-month detraining after a 6-month ET (DT, n = 15), and a medical treatment only group (MT, n = 30). For ET, cycling on a bicycle ergometer was performed in the DT and CT groups 3 times a week for 6 and 12 months, respectively. Each session started with a 10-minute warmup at 60% to 70% of the maximal heart rate (HRpeak), followed by four 4-minute intervals at 80% to 90% of the HRpeak, with 3 minutes of active recovery at 60% to 70% of the HRpeak between intervals, ending with a 5-minute cooldown period. Peak exercise oxygen consumption (Vo2), intimal-medial thickness (IMT) of the carotid artery measured on high-resolution ultrasonography, and left ventricular function were measured at baseline, after 6 months of training, and after additional 6 months of continuous training or detraining follow-up assessments. In addition, plasma von Willebrand factor (vWF), endothelin-1, nitric oxide, tumour necrosis factor alpha, interleukin-1 beta, interleukin-6, and interleukin-10 levels were measured as indices of endothelial function.
Results
The 6-month ET increased peak Vo2 (CT: 29.0 ± 6.5 ml/[kg·min] and DT: 26.0 ± 8.2 ml/[kg·min] vs. MT: 23.0 ± 5.2 ml/[kg·min], p = 0.04) and decreased plasma vWF levels (CT: 103.7 ± 30.7 IU/dL and DT: 106.0 ± 31.2 IU/dL vs. MT: 145.0 ± 47.7 IU/dL, p = 0.01). Detraining significantly reduced the ET-induced increase in Vo2 and decreased the vWF to baseline level, although continuous ET maintained changes in Vo2 (CT: 28.1 ± 5.3 ml/[kg·min] and DT: 22.4 ± 6.6 ml/[kg·min] vs. MT: 21.5 ± 4.8 ml/[kg·min], p = 0.043) and in vWF (CT: 84.3 ± 39.1 IU/dL vs. DT: 122.2 ± 27.5 IU/dL and MT: 135.9 ± 50.4 IU/dL, p = 0.014). However, carotid arterial IMT, and resting left ventricular systolic and diastolic functions showed no significant changes, with no inter-group differences after 6 months of training and 6 months of continuous training or detraining.
Conclusions
The decreased vWF level suggested that ET can be a strong non-pharmacologic option to improve endothelial function in patients with AF. However, it can rapidly lose its effects after detraining. Therefore, physicians should encourage their patients to participate in a continuous exercise program to sustain its benefits in terms of improved exercise capacity and endothelial function in patients with AF.

Abstract
Abstract
Introduction
We aimed to determine whether maximal exercise capacity, left ventricular function, and quality of life (QoL) scores are sustained in patients with atrial fibrillation (AF) after termination of training following exercise-based cardiac rehabilitation (ECR).
Methods
In a prospective study, 58 patients with AF (age, 62 ± 7 years) were randomized into an exercise training group for 12 months (ECR, n = 13), a group with 6-month detraining after a 6-month exercise training (DT, n = 15), and a medical treatment only group (MT, n = 30). For exercise training, cycling on a bicycle ergometer was performed in the DT and ECR groups 3 times a week for 6 and 12 months, respectively. Each session started with a 10-minute warm-up at 60%–70% of the maximal heart rate (HRpeak), followed by four 4-minute intervals at 80%–90% of the HRpeak, with 3 minutes of active recovery at 60%–70% of the HRpeak between intervals, ending with a 5-minute cool-down period. Peak exercise oxygen consumption (Vo2), left ventricular function, plasma lipid level, N-terminal pro B-type natriuretic peptide level, and QoL score were measured at baseline, after 6 months of training, and after additional 6 months of continuous training or detraining follow-up assessments.
Results
Six months of exercise training increased the peak Vo2 (ECR: 28.2 ± 7.0 ml/[kg·min] and DT: 28.0 ± 8.3 ml/[kg·min] vs. MT: 23.0 ± 5.2 ml/[kg·min], p= 0.047) and QoL scores (36-Item Short-form Health Survey) and decreased the total cholesterol level (ECR: 146.8 ± 43.8 mg/dl and DT: 140.6 ± 22.4 vs. MT: 182 ± 44.2 mg/dl, p = 0.008). Detraining resulted in an increase in QoL score and a decrease in total cholesterol level (ECR: 142.8 ± 21.4 mg/dl and DT: 151.8 ± 39.8 vs. MT: 176.8 ± 34.2 mg/dl, p = 0.017). However, the exercise training-induced increase in peak Vo2 reverted to the baseline level after detraining (ECR: 27.1 ± 5.1 ml/kg/min vs. DT: 24.4 ± 7.2 ml/[kg·min] and MT: 21.5 ± 4.86 ml/[kg·min], p = 0.017). The resting left ventricular systolic and diastolic functions were not significantly different, with no inter-group difference after 6 months of training and 6 months of continuous training or detraining.
Conclusions
As the QoL scores are maintained despite peak Vo2 being lowered by detraining after an exercise training period in patients with AF, physicians should encourage patients’ participation in a continuous exercise program to sustain the improvement in both the QoL score and peak Vo2 with exercise training. Further studies with larger sample sizes are needed to observe the long-term effects of exercise training and detraining.

Abstract
BACKGROUND AND PURPOSE Rosiglitazone is a widely used oral hypoglycaemic agent, which improves insulin resistance in type 2 diabetes. Chronic rosiglitazone treatment is associated with a number of adverse cardiac events. The present study was designed to characterize the effects of rosiglitazone on cloned K(v)4.3 potassium channels. EXPERIMENTAL APPROACH The interaction of rosiglitazone with cloned K(v)4.3 channels stably expressed in Chinese hamster ovary cells was investigated using whole-cell patch-clamp techniques. KEY RESULTS Rosiglitazone decreased the currents carried by K(v)4.3 channels and accelerated the current inactivation, concentration-dependently, with an IC(50) of 24.5 µM. The association and dissociation rate constants for rosiglitazone were 1.22 µM(-1)·s(-1) and 31.30 s(-1) respectively. Block by rosiglitazone was voltage-dependent, increasing in the voltage range for channel activation; however, no voltage dependence was found in the voltage range required for full activation. Rosiglitazone had no effect on either the deactivation kinetics or the steady-state activation of K(v)4.3 channels. Rosiglitazone shifted the steady-state inactivation curves in the hyperpolarizing direction, concentration-dependently. The K(i) for the interaction between rosiglitazone and the inactivated state of K(v)4.3 channels was 1.49 µM, from the concentration-dependent shift in the steady-state inactivation curves. Rosiglitazone also accelerated the kinetics of the closed-state inactivation of K(v)4.3 channels. Rosiglitazone did not affect either use dependence or recovery from inactivation of K(v)4.3 currents. CONCLUSION AND IMPLICATIONS Our results indicate that rosiglitazone potently inhibits currents carried by K(v)4.3 channels by interacting with these channels in the open state and by accelerating the closed-state inactivation of K(v)4.3 channels.

Abstract
AIM Ataxia telangiectasia mutated (ATM) reportedly plays a role in insulin-stimulated activation of Akt in some cell types but not in others. The role of ATM in insulin signalling has not been firmly resolved for skeletal muscle cells, for which Akt phosphorylation is a pivotal step in stimulation of glucose transport. Accordingly, our aim was to determine the role of ATM in insulin effects for cell lines derived from skeletal muscle and for skeletal muscle. METHODS We examined insulin effects in L6 myotubes, mouse soleus, C2C12 myotubes and differentiated rhabdomyosarcoma (RD) cells in the presence and absence of a low concentration (1 microm) of the ATM inhibitor KU55933. We also compared insulin signalling in C2C12 cells expressing shRNA against ATM and control cell lines (empty vector; cells expressing non-targeting shRNA). RESULTS In L6 myotubes and mouse soleus muscle, KU55933 inhibited insulin-stimulated phosphorylation of the 160 kDa substrate of Akt (AS160) despite no effect on Akt. In contrast, KU55933 prevented insulin-stimulated Akt phosphorylation in C2C12 myotubes. Furthermore, C2C12 myotubes expressing shRNA against ATM displayed reduced insulin-stimulated Akt phosphorylation compared to controls. KU55933 also decreased insulin-stimulated Akt phosphorylation in differentiated RD cells. CONCLUSION These model-dependent differences in the role of ATM in insulin action demonstrate a role of ATM in insulin-stimulated phosphorylation of Akt (in C2C12 and RD cells) but also allow the elucidation of a novel, Akt-independent role of ATM (in L6 myotubes and mouse soleus, at the level of AS160) in insulin signalling.
