Online Social Networks (OSN) sites allow end-users to share agreat deal of information, which may also contain sensitive information,that may be subject to commercial or non-commercial privacy attacks. Asa result, guaranteeing various levels of privacy is critical while publishingdata by OSNs. The clustering-based solutions proved an effective mechanismto achieve the privacy notions in OSNs. But fixed clustering limits theperformance and scalability. Data utility degrades with increased privacy,so balancing the privacy utility trade-off is an open research issue. Theresearch has proposed a novel privacy preservation model using the enhancedclustering mechanism to overcome this issue. The proposed model includesphases like pre-processing, enhanced clustering, and ensuring privacy preservation.The enhanced clustering algorithm is the second phase where authorsmodified the existing fixed k-means clustering using the threshold approach.The threshold value is determined based on the supplied OSN data of edges,nodes, and user attributes. Clusters are k-anonymized with multiple graphproperties by a novel one-pass algorithm. After achieving the k-anonymityof clusters, optimization was performed to achieve all privacy models, suchas k-anonymity, t-closeness, and l-diversity. The proposed privacy frameworkachieves privacy of all three network components, i.e., link, node, and userattributes, with improved utility. The authors compare the proposed techniqueto underlying methods using OSN Yelp and Facebook datasets. The proposedapproach outperformed the underlying state of art methods for Degree ofAnonymization, computational efficiency, and information loss. 展开更多

Objective Robotic-assisted live donor nephrectomy(LDN)is being gradually adopted across transplant centers.The left donor kidney is preferred over right due to anatomical factors and ease of procurement.We aimed to study donor and recipient outcomes after robotic procurement and subsequent open implantation of right and left kidneys.Methods All fully robotic LDNs and their corresponding open kidney transplants performed at our center between February 2016 and December 2021 were retrospectively analyzed.Results Out of 196 robotic LDN(49[right]vs.147[left]),10(5.1%)donors had intra-operative events(6.1%[right]vs.4.8%[left],p=0.71).None of the LDN required conversion to open surgery.The operative times were comparable for the two groups.Nausea(13.3%)was the most common post-operative complication.There was no mortality in either LDN group.Herein,we report our outcomes on 156 recipients(39 right and 117 left allografts)excluding robotic implants,exports,and pediatric recipients.There were no significant differences between right and left kidney recipients with respect to 1-year post-transplant patient survival(100.0%vs.98.1%,p=0.45)or graft survival(93.9%vs.97.1%,p=0.11),or delayed graft function(7.7%vs.5.1%,p=0.55).Conclusion Non-hand-assisted robotic live donor nephrectomies can be safely performed with excellent outcomes.Right LDN was not associated with higher incidence of complications compared to left LDN.Open implantation of robotically procured right renal allografts was not associated with higher risk of recipient complications. 展开更多

In many dioecious plants, gender affects economic value, breeding schemes and opportunities for commercial harvests. Hippophae rhamnoides L. is a dioecious plant species in which female genotypes are commercially preferred over male genotypes. Its berries have rich medicinal, nutritional and pharmaceutical properties because of their large amounts of vitamins, essential oils, proteins, fatty acids, free amino acids and flavanoids. Primary limitation for breeding H. rhamnoides L. is its dioecious nature, since gender cannot be identified by traditional methods. Therefore, some reliable and quick methods need to be developed. This communication deals with the development of isozyme and RAPD markers for early sex identification in this dioecious tree. The isozyme analysis was conducted with four enzyme systems, viz. peroxidase, esterase, malate dehydrogenase and catalase. The peroxidase enzyme system produced a female specific sex marker, which successfully differentiated between the staminate and pistillate genotypes of H. rhamnoides L. Thirty five random decamer primers were used in our study and one male sex linked marker was identified. OPD-20 (5′-ACTTCGCCAC-3′) displayed a band at 911 bp that expressed polymorphism between male and female genotypes. The staminate and pistillate genotypes could be distinguished using RAPD marker OPD-20911. These results revealed the immense potential of peroxidase isozyme patterns and RAPD as genetic markers for sex identification in H. rhamnoides L. 展开更多

The therapeutic value of mesenchymal stem cells (MSCs) for the treatment of infectious diseases and the repair of disease-induced tissue damage has been explored extensively. MSCs inhibit inflammation, reduce pathogen load and tissue damage encountered during infectious diseases through the secretion of antimicrobial factors for pathogen clearance and they phagocytose certain bacteria themselves. MSCs dampen tissue damage during infection by downregulating thelevels of pro-inflammatory cytokines, and inhibiting the excessive recruitment ofneutrophils and proliferation of T cells at the site of injury. MSCs aid in theregeneration of damaged tissue by differentiating into the damaged cell types orby releasing paracrine factors that direct tissue regeneration, differentiation, andwound healing. In this review, we discuss in detail the various mechanisms bywhich MSCs help combat pathogens, tissue damage associated with infectiousdiseases, and challenges in utilizing MSCs for therapy. 展开更多

Pulmonary vein thrombosis(PVT) is a rarely encountered disease entity with varied clinical presentations. It is usually associated with lung carcinoma, lung surgeries and as a complication of the radiofrequency catheter ablation procedure for atrial fibrillation. Its clinical manifestations can vary from mild hemoptysis to lung infarction with hemodynamic compromise. A 76-year-old male presented with a 2-d history of pleuritic left sided chest pain. His past medical history included polycythemia vera, atrial fibrillation, coronary artery disease, pulmonary embolism and pulmonary hypertension. Chest radiograph was normal, troponins were normal and the 12-lead electrocardiogram did not show any ischemic changes. A computerized tomography pulmonary angiogram revealed a filling defect in the left lower lobe pulmonary vein. He was treated with subcutaneous enoxaparin and his symptoms improved. This case highlights a rare etiology of chest pain and the first reported case of the association of polycythemia vera and pulmonary vein thrombosis. A high index of suspicion is required for appropriate diagnostic work up. PVT can mimic pulmonary embolism. The diagnostic work up and treatment strategies depend on acuity of presentation. 展开更多

We present a model of a universe that transitions from an early deceleration phase to the current acceleration phase under the framework of general relativity, in the presence of gravitational coupling G(t) and cosmological terms Λ(t). Einstein's field equations have been solved by considering the time dependent deceleration parameter (DP) which renders the scale factor a=(tnekt)1/m where m, n and k are positive constants. The cosmological term (Λ(t)) is found to be positive and a decreasing function of time, which supports the result obtained from observations of type Ia supernovae. The geometrical and kinematical features of the model are examined in detail. 展开更多

We investigate direction dependence and non-Gaussian features in high-z cosmological data using ?_(χ~2) and ?_χ statistics and the Kolmogorov-Smirnov test. These techniques are applied on a set of calibrated long gamma-ray bursts(GRBs) and its combination with recent Type Ia supernovae data(Union2). Our statistical analysis shows a weak but consistent direction dependence in both the data sets.The analysis also indicates a non-Gaussian nature of errors in both data sets. 展开更多

The nature of random errors in any data set is Gaussian, which is a well established fact according to the Central Limit Theorem. Supernovae type Ia data have played a crucial role in major discoveries in cosmology. Unlike in laboratory experiments, astronomical measurements cannot be performed in controlled situations. Thus, errors in astronomical data can be more severe in terms of systematics and non-Gaussianity compared to those of laboratory experiments. In this paper, we use the Kolmogorov-Smirnov statistic to test non-Gaussianity in high-z supernovae data. We apply this statistic to four data sets, i.e., Gold data(2004),Gold data(2007), the Union2 catalog and the Union2.1 data set for our analysis. Our results show that in all four data sets the errors are consistent with a Gaussian distribution. 展开更多

In general, a supplier/retailer frequently offer trade credit to stimulate their respective sales. The main purpose of this paper is to investigate the optimal supplier/retailer’s replenishment decisions under two levels of trade credit policy within the economic order quantity (EOQ) framework. This paper deals with the supplier/retailer’s inventory replenishment problem under two levels of trade credit in one replenishment cycle. A different approach of two levels of trade credit is used, which give more freedom to the supplier/retailer in business. In addition, the easy-to-use procedure is developed to efficiently find the optimal cycle time for the retailer under minimizing annual total relevant cost. Finally, a numerical example is given to illustrate these results. 展开更多

Fluorescence imaging is a non-invasive and highly sensitive bioimaging technique that has shown remarkable strides in plant science. It enables real-time monitoring and analysis of biological and pathological processes in plants by labeling specific molecular or cellular structures with fluorescent probes. However, tissue scattering and phytochrome interference have been obstacles for conventional fluorescence imaging of plants in the ultraviolet and visible spectrum, resulting in unsatisfactory imaging quality. Fortunately, advances in near-infrared(NIR) fluorescence imaging technology(650-900 nm) offer superior spatial-temporal resolution and reduced tissue scattering, which is sure to improve plant imaging quality. In this review, we summarize recent progress in the development of NIR fluorescence imaging probes and their applications for in vivo plant imaging and the identification of plant-related biomolecules. We hope this review provides a new perspective for plant science research and highlights NIR fluorescence imaging as a powerful tool for analyzing plant physiology, adaptive mechanisms, and coping with environmental stress in the near future. 展开更多

Although cancer immunotherapy has taken center stage,exhaustion of T cells is undeniably one of the major problems preventing it from being fully successful[1].Certainly,reversal of T-cell exhaustion or dysfunction is of great importance for developing new strategies and restoring immune function.Nevertheless,counterarguments about the adverse effect of reversing T-cell exhaustion(leading to overactivation of T cells and cytotoxicity)and even their irreversible properties have been quite common in scientific debates.With more to be discovered about the reasons for T-cell failure,a better understanding of the molecular factors/determinants[2,3]that shape/remodel“heterogeneous”dysfunctional T cells in cancer makes clear sense.Indeed,two recent publications in Nature immunology have described the intriguing perspective of T-cell exhaustion[4,5].Of interest,Vignali et al.focused on the hypoxia-driven CD39-dependent suppressor function of exhausted T cells,whereas Saadey et al.emphasized restoring the epigenetic balance of TGFβ1/BMP signaling in exhausted T cells to unlock responsiveness to immune checkpoint blockade therapy. 展开更多
