Out of the three major categories of cardiomyopathies （hypertrophic, dilated and restrictive）, restrictive cardiomyopathy （RCM） is less common and also the least studied. However, the prognosis for RCM is poor as some patients dying in their childhood. The molecular mechanisms behind the disease development and progression are not very clear and the treatment of RCM is very difficult and often ineffective. In this article, we reviewed the recent progress in RCM research from the clinical studies and the translational studies done on diseased transgenic animal models. This will help for a better understanding of the mechanisms underlying the etiology and development of RCM and for the design of better treatments for the disease.展开更多

We used restriction enzyme digestion to test the mutation in the family members and 200 unrelatednormal subjects without any cardiac inherited diseases when the mutation was identified.Results Five individuals died from cardiac diseases, two of whom suffered from sudden cardiacdeath. Two individuals have suffered from chronic cardiac disorders. Mutation analysis revealed a novelmissense mutation in exon 7 of troponin I type 3 （TNNI3）, resulting in substitution of serine （S） withproline （P） at amino acid position 150, which cosegregated with the disease in the family, which is predictedto be probably damaging using PolyPhen-2. The mutation was not detected in the 200 unrelated subjectswe tested.Conclusion Using next generation sequencing, which has very recently been shown to be successfulin identifying novel causative mutations of rare Mendelian disorders, we found a novel mutation of TNNI3 in aChinese family with RCM.展开更多

The restrictive ecological factors, including causing ecological factors, such as COD/SO 4 2- ratio and sulfate loading rate (Ns), and following ecological factors, such as pH value, oxidation reduction potential (ORP) and alkalinity (ALK) have significant effect on the ability and stability of acidogenic de sulfate bio reactor. Continuous flow and batch test were carried out to investigate the quantification and control of COD/SO 4 2- ratio, Ns, pH value, ORP and ALK in acidogenic de sulfate bioreactor supplied with molasses wastewater as sole organic carbon source and sodium sulfate as electron donor. It was demonstrated that In order to maintain high sulfate removal rate (SRR) of 80% to 90%, the restrictive factors should meet all the requirement as follows: k COD/ SO 4 2- ratio≥2.0, Ns≤7.5 kg (m 3·d) -1 ,pH=5.7～6.2,ORP=-320～-420 mV and ALK= 1 500～2 000 mg/L.展开更多

One ...Network virtualization(NV) is widely considered as a key component of the future network and promises to allow multiple virtual networks(VNs) with different protocols to coexist on a shared substrate network(SN). One main challenge in NV is virtual network embedding(VNE). VNE is a NPhard problem. Previous VNE algorithms in the literature are mostly heuristic, while the remaining algorithms are exact. Heuristic algorithms aim to find a feasible embedding of each VN, not optimal or sub-optimal, in polynomial time. Though presenting the optimal or sub-optimal embedding per VN, exact algorithms are too time-consuming in smallscaled networks, not to mention moderately sized networks. To make a trade-off between the heuristic and the exact, this paper presents an effective algorithm, labeled as VNE-RSOT(Restrictive Selection and Optimization Theory), to solve the VNE problem. The VNERSOT can embed virtual nodes and links per VN simultaneously. The restrictive selection contributes to selecting candidate substrate nodes and paths and largely cuts down on the number of integer variables, used in the following optimization theory approach. The VNE-RSOT fights to minimize substrate resource consumption and accommodates more VNs. To highlight the efficiency of VNERSOT, a simulation against typical and stateof-art heuristic algorithms and a pure exact algorithm is made. Numerical results reveal that virtual network request(VNR) acceptance ratio of VNE-RSOT is, at least, 10% higher than the best-behaved heuristic. Other metrics, such as the execution time, are also plotted to emphasize and highlight the efficiency of VNE-RSOT.展开更多

A one-stage, randomized study involved 80 obese women aged 20 to 58 years. The inclusion criterion for selecting participants for this research was the presence of primary alimentary-constitutional obesity with body mass index equal to or higher than 30 kg/m2. All the women were distributed into three groups according to the set of applied treatments. In Group 1, the women were on a restrictive diet;in Group 2, the restrictive diet was accompanied with daily aerobic exercise;in Group 3, women were exposed to bright light during exercise. Before and after the treatment course (3 weeks), body weight, waist and hip circumferences were measured;fat amount was determined by the impedancemetry method;and oxygen consumption was determined by indirect calorimetry. Women in Group 1 had reduced body weight, waist and hip circumferences, fat mass and oxygen consumption. Similar changes were identified in women of Group 2, but weight loss was greater, and the level of oxygen consumption increased as compared to the baseline. In women of Group 3, weight loss and increased oxygen consumption were more pronounced than in those of Group 2. The number of metabolic equivalents (MET) in women of Group 3 increased to nearly 1, which corresponded to the value of this index that reflected the resting metabolic rate in patients with normal body weight. Thus, exposure to bright full-spectrum light increases energy metabolism and enhances the effectiveness of exercises, despite prolonged food restriction, which is one of the mechanisms to improve the efficiency of obesity correction.展开更多

However, the safest and the effective blood transfusion strategy is controversial. Here, we studied the safety and the effectiveness of the restrictive versus liberal transfusion strategies in patients with esophageal variceal bleeding. Patients and Methods: The study included 342 patients with esophageal variceal bleeding. Patients were divided into 2 groups: group I (Restrictive strategy) transfusion when the hemoglobin level is ≤7 g/dl and group II (Liberal strategy): transfusion when the hemoglobin level is ≤9 g/dl. All patients were subjected to complete blood counts, liver and kidney profiles, coagulation profile, pelvi-abdominal ultrasonography and upper GI endoscopy. Clinical outcome measures include rebleeding, infection, allergic transfusion reactions thromboembolic events, and mortality. Results: Of all patients admitted to hospital with esophageal variceal bleeding, the number of transfused RBCs units and hospital stay were more in the liberal transfusion strategy. Also, the overall rate of complications was higher in the liberal transfusion strategy (49.7% versus 38.5% in the restrictive transfusion strategy). The most common complications were rebleeding (26.9%) and infection (21.6%). As regard the death rate, 13 cases (7.6%) died in the restrictive transfusion strategy versus 25 cases (14.6%) in the liberal transfusion one. Conclusions: For esophageal variceal bleeding, restrictive transfusion strategy is better than the liberal one as regard cost-effectiveness, risk of complications and hospital stay with no harm and less mortality as compared to liberal strategy.展开更多

The restrictive selection contributes to selecting candidate substrate nodes and paths and largely cuts down on the number of integer variables, used in the following optimization theory approach. The VNE-RSOT fights to minimize substrate resource consumption and accommodates more VNs. To highlight the efficiency of VNERSOT, a simulation against typical and stateof-art heuristic algorithms and a pure exact algorithm is made. Numerical results reveal that virtual network request(VNR) acceptance ratio of VNE-RSOT is, at least, 10% higher than the best-behaved heuristic. Other metrics, such as the execution time, are also plotted to emphasize and highlight the efficiency of VNE-RSOT.
文摘Chronic lung allograft dysfunction(CLAD)following lung transplantation limits long-term survival considerably.The main reason for this is a lack of knowledge regarding the pathological condition and the establishment of treatment.The consensus statement from the International Society for Heart and Lung Transplantation on CLAD in 2019 classified CLAD into two main phenotypes:Bronchiolitis obliterans syndrome and restrictive allograft syndrome.Along with this clear classification,further exploration of the mechanisms and the development of appropriate prevention and treatment strategies for each phenotype are desired.In this review,we summarize the new definition of CLAD and update and summarize the existing knowledge on the underlying mechanisms of bronchiolitis obliterans syndrome and restrictive allograft syndrome,which have been elucidated from clinicopathological observations and animal experiments worldwide.
文摘Literary translation is not merely the transformation of words,but it is a cross-cultural activity from cultural perspective.The paper mainly explores the concept of cultural context and the relationship between cultural context and literary translation,and analyzes explanatory function and restrictive function of cultural context in literary translation.If these functions can be involved in the literary translation,it is necessary for translators to resort to different translation strategies according to the different target cultural context.The selection of translation strategies is never random,but constrained by the cultural context.
文摘BACKGROUND Diabetes is a progressive disease that increases glucose levels in the blood.While studies have shown that patients with pulmonary disease(both obstructive and restrictive pulmonary disease)have a higher prevalence of type 2 diabetes mellitus(T2DM),there have been more studies on restrictive patterns than chronic obstructive pulmonary disease.AIM To assess whether restrictive and obstructive pulmonary diseases are associated with T2DM in Koreans.METHODS For our analysis,we used data from the Korea National Health and Nutrition Examination Survey.A total of 2830 subjects were included in this study.Spirometry results were categorized into three patterns:Normal,restrictive pulmonary disease(RPD),and obstructive pulmonary disease(OPD).RESULTS The factors used as diabetic indicators(i.e.homeostatic model assessment of insulin resistance,homeostatic model assessment of beta-cell function,glycated hemoglobin,and fasting insulin)were among the highest in RPD but not in OPD.Based on multivariate logistic regression analysis,subjects with RPD were found with an increased odds ratio[OR:1.907,95%confidence interval(CI):1.110-3.277]for T2DM compared with subjects with normal pulmonary function,whereas in patients with OPD,the OR had not increased.Model 4,which adjusted for the variables that could affect diabetes and pulmonary disease,showed a significant increase in the T2DM OR to RPD(OR:2.025,95%CI:1.264-3.244).On the other hand,no statistically significant difference was shown in OPD(OR:0.982,95%CI:0.634-1.519).CONCLUSION RPD,not OPD,is highly associated with T2DM regardless of the risk factors of various T2DMs that can be confounds.
文摘In this paper, a new restrictive blind signature scheme is proposed. Compared with Brands restrictive blind signature scheme, our scheme is even more restrictive and efficient. And our scheme is proved secure, too. A new withdrawal protocol of electronic cash system is designed by using our restrictive blind signature scheme, which is more efficient than the withdrawal protocol and is more appropriate for adopting pre processing and post processing.
文摘The purpose of this study was to analyze the effectiveness of measures aimed at correcting obesity in women and including bright light exposure during aerobic exercise combined with a restrictive diet. A one-stage, randomized study involved 80 obese women aged 20 to 58 years. The inclusion criterion for selecting participants for this research was the presence of primary alimentary-constitutional obesity with body mass index equal to or higher than 30 kg/m2. All the women were distributed into three groups according to the set of applied treatments. In Group 1, the women were on a restrictive diet;in Group 2, the restrictive diet was accompanied with daily aerobic exercise;in Group 3, women were exposed to bright light during exercise. Before and after the treatment course (3 weeks), body weight, waist and hip circumferences were measured;fat amount was determined by the impedancemetry method;and oxygen consumption was determined by indirect calorimetry. Women in Group 1 had reduced body weight, waist and hip circumferences, fat mass and oxygen consumption. Similar changes were identified in women of Group 2, but weight loss was greater, and the level of oxygen consumption increased as compared to the baseline. In women of Group 3, weight loss and increased oxygen consumption were more pronounced than in those of Group 2. The number of metabolic equivalents (MET) in women of Group 3 increased to nearly 1, which corresponded to the value of this index that reflected the resting metabolic rate in patients with normal body weight. Thus, exposure to bright full-spectrum light increases energy metabolism and enhances the effectiveness of exercises, despite prolonged food restriction, which is one of the mechanisms to improve the efficiency of obesity correction.

文摘Objective:To study the effects of hyperbaric oxygen preconditioning on the postoperative oxidative stress activation in patients with total knee arthroplasty (TKA) and total hip arthroplasty (THA) restrictive transfusion.Methods: Patients who underwent THA and TKA and received restrictive transfusion in the Sixth Affiliated Hospital of Xinjiang Medical University and Bazhou People's Hospital of Korla between June 2014 and December 2017 were selected and divided into HBOPC group and control group according to the application of preoperative hyperbaric oxygen preconditioning or not. The contents of oxidative stress indexes in serum as well as the expression intensity of oxidative stress molecules and immune molecules in peripheral blood were determined before surgery and 24 h after surgery.Results:Compared with those of same group before surgery, serum COR, NE, AT-II, MDA and ROS contents as well as peripheral blood JNK, Akt, FoxO3a, Nrf2, ARE, Foxp3 and GATA-3 expression intensity of both groups significantly increased whereas peripheral blood CD3, CD4 and T-bet expression intensity significantly decreased, and serum COR, NE, AT-II, MDA and ROS contents as well as peripheral blood JNK, Akt, FoxO3a, Nrf2, ARE, Foxp3 and GATA-3 expression intensity of HBOPC group after surgery were lower than those of control group whereas peripheral blood CD3, CD4 and T-bet expression intensity were higher than those of control group.Conclusion: Hyperbaric oxygen preconditioning can improve the postoperative oxidative stress response activation and immune response disorder in patients with TKA and THA restrictive transfusion.
文摘Background and Study Aim: Esophageal variceal bleeding is a major medical emergency and one of the most important indications for hospital admission and for blood transfusion. However, the safest and the effective blood transfusion strategy is controversial. Here, we studied the safety and the effectiveness of the restrictive versus liberal transfusion strategies in patients with esophageal variceal bleeding. Patients and Methods: The study included 342 patients with esophageal variceal bleeding. Patients were divided into 2 groups: group I (Restrictive strategy) transfusion when the hemoglobin level is ≤7 g/dl and group II (Liberal strategy): transfusion when the hemoglobin level is ≤9 g/dl. All patients were subjected to complete blood counts, liver and kidney profiles, coagulation profile, pelvi-abdominal ultrasonography and upper GI endoscopy. Clinical outcome measures include rebleeding, infection, allergic transfusion reactions thromboembolic events, and mortality. Results: Of all patients admitted to hospital with esophageal variceal bleeding, the number of transfused RBCs units and hospital stay were more in the liberal transfusion strategy. Also, the overall rate of complications was higher in the liberal transfusion strategy (49.7% versus 38.5% in the restrictive transfusion strategy). The most common complications were rebleeding (26.9%) and infection (21.6%). As regard the death rate, 13 cases (7.6%) died in the restrictive transfusion strategy versus 25 cases (14.6%) in the liberal transfusion one. Conclusions: For esophageal variceal bleeding, restrictive transfusion strategy is better than the liberal one as regard cost-effectiveness, risk of complications and hospital stay with no harm and less mortality as compared to liberal strategy.
文摘The problem of solving the linear diffusion equation by a method related to the Restrictive Pade Approximation (RPA) is considered. The advantage is that it has the exact value at certain r. This method will exhibit several advantages for example highly accurate, fast and with good results, etc. The absolutely error is still very small. The obtained results are compared with the exact solution and the other methods. The numerical results are in agreement with the exact solution.

文摘The development of more adequate food programs regarding the intensity and duration of the restriction can be an effective way to minimize the effects of exaggerated food consumption and its negative consequences for the economy of the business.In this sense,juvenile Nile tilapia(Oreochromis niloticus)(137±3 g)were submitted to different feeding strategies in a recirculation system.Five feeding strategies were tested in subsequent weekly cycles:continuous feeding;skipping one meal a week;suppression of two non-consecutive meals a week;suppression of three non-consecutive meals a week;suppression of four non-consecutive meals a week.Productive performance,feed consumption in the post-restriction period and economic indicators were evaluated through projections and profitability analyses.Compensatory intake occurred in all tested groups,so that the total feed intake(FI)did not differ significantly between them(p>0.05).Moderate food restriction provided a linear increase in the relative gross margin for each treatment with each change in salary level,as well as greater profitability when compared to the respective control group(p<0.05).
