     Background: The aim of this study was to analyze angiographic parameters such as bifurcation angle, diameter at the polygon of confluence (POC) and SYNTAX score in predicting the need for side branch treatment with single-stent crossover technique from distal unprotected left main coronary artery (ULMCA) to the major side branch.Methods: This was a retrospective and observational study. A total of 83 patients with distal ULMCA lesions were enrolled. Patients who underwent provisional single-stent crossover technique were compared with patients that required side branch treatment though plain old balloon angioplasty (POBA) 5 (6.0%) or stenting 7 (8.4%). Angiographic parameters, bifurcation angle, diameter at the POC and the SYNTAX score were analyzed for their ability to predict the need for side branch treatment.Results: Mean age of patients was 58.2±5.3 years. Males constituted 61 (73.5%) patients. Post main branch stenting 5 (6.0%) and 7 (8.4%) patients required side branch treatment with POBA and stent implantation, respectively. Binary regression revealed bifurcation angle (Z: 1.15, OR: 0.99, 95% CI: 0.97-1.01, p=0.25), diameter at the POC (Z: 1.1, OR: 0.82, 95% CI: 0.32-2.13, p=0.272) and SYNTAX score (Z: 1.51, OR: 1.18, 95% CI: 0.95-1.45, p=0.132) did not correctly predict the requirement of side branch treatment.Conclusion: Left main coronary artery to main branch stenting can be performed safely with single-stent crossover technique, irrespective of presence of side branch disease across a wide range of bifurcation angles, diameters at the POC and SYNTAX scores.

    The corona virus is now known as the severe acute respiratory syndrome corona virus 2 (SARS-CoV-2). Risk predictors and novel predictors associated with COVID-19 is required to enable the risk stratification, guide interventional studies to target patients at enhanced risk of developing severe disease risk and optimize the allocation of limited human and technical resources in the ongoing pandemic all over the globe. The present review focused on potential laboratory biomarkers associated with COVID-19. We carried out an electronic search in Medline (PubMed central), Scopus, Web of Science and using the keywords laboratory, biomarkers, novel biomarkers, corona virus 2019 or COVID-19. We observed that limited data were found that related to homocysteine and angiotensin II in COVID-19 patients. Hence original research on these novel biomarkers which associated with the complication of COVID-19 might be given new clues especially that mediate anti-inflammatory and anti-fibrotic effects leading to cardiovascular, renal-protective actions. The present review proposed by the available literature, these predictors might be the potent biomarkers to improve management of corona virus. Further, large cohort studies will be required to support conclusions of present review

    In last couple of years there huge increase in the usage cloud computing because cloud computing is emerging style of IT-delivery in which applications, data and resources are rapidly provisioned provided as standardized offerings to users with a flexible price. But it is important to provide the convenient pricing model for the users of cloud. Hence we design a new traffic redundancy and elimination scheme for reducing the cloud bandwidth and costs. Cloud computing is a fast growing field which is arguably a new computing paradigm. In cloud computing, computing resources are provided as services over the internet and users can access resources by paying. When we are trying to minimize the cloud cost, transmission cost plays a major role. In this paper, we present PACK (Predictive ACKs) mechanism, a novel end-to-end traffic redundancy elimination (TRE) system, designed for cloud computing customers. During this     paper we provide a survey on the new traffic redundancy technique called novel-TRE conjointly called receiver based TRE. This novel-TRE has important options like detective work the redundancy at the customer, randomly rotating appear chained, matches incoming chunks with a antecedently received chunk chain or native file and sending to the server for predicting the long run information and no would like of server to unceasingly maintain consumer state

    Active Cloud Valuing for Revenue Expansion

    Cloud computing is an emerging computing paradigm in which resources of the computing infrastructure are provided as services over the Internet. Sharing data in a multiowner manner while preserving data and identity privacy from an untrusted cloud is still a challenging issue, due to the frequent change of the membership. To preserve data privacy, a basic solution is to encrypt data files, and then upload the encrypted data into the cloud. In this paper we are further extending the basic MONA by adding the reliability as well as improving the scalability by increasing the number of group managers dynamically. This paper proposes how user can access data after the time out. The storage overhead and encryption computation cost of our scheme are independent with the number of revoked users

    Studies on Genetic Divergence in Pomegranate (Punica granatum L.) Using SRAP Markers

    Pomegranate genotypes have been characterized mainly on the basis of morphological traits; but, these traits are affected to a large extent by environmental and cultivation conditions, resulting in their ambiguous discrimination. Molecular markers are more suited for accurate discrimination of genotypes and cultivars. Sequence-Related Amplified Polymorphism (SRAP) markers were used in the present study to analyze polymorphism among the important pomegranate genotypes grown in India. The total number of bands generated by 30 SRAP primers for 12 genotypes was 1448, with an average of 48.3 bands per primer. Polymorphism varied from 2.7 to 73.9, with an average of 40.95%. Similarity-value based on Jaccard's Coefficient ranged from 0.63 (between cvs. Naina and Amlidana) to 0.95 (between cvs. Kabul Yellow and Jalore Seedless). UPGMA (un-weighted pair group method with arithmetic mean) analysis was performed and a dendrogram was constructed using Jaccard's similarity matrix. The 12 genotypes used grouped into 5 clusters. SRAP markers were found suitable for determining variability among the pomegranate genotypes studied

    The exfoliation of two dimensional (2D) transition metal dichalcogenides (TMDs) into mono- or few-layers without compromising their semiconductor properties has momentous interest for both point of view; fundamental studies and further implementation in practical applications. Herein, we reported a novel and inexpensive approach for high yield nanosheets from bulk MoS2 to few layers of strong luminescent MoS2 nanosheets using Triton X-100 as a surfactant with tailoring the bulk band gap 1.2 eV to 1.79 eV of few layers of nanosheets after chemical exfoliation process, which can be easily scaled-up in large quantity. The microstructural results reveal that the exfoliated nanosheets have thickness in the range of few layers and lateral dimension in the range of few hundred nanometers. Our findings may offer a new innovative one setup chemical exfoliation process to design a few layer of MoS2 nanosheets without suppressing luminescent properties, which is highly desirable for the next generation optoelectronic devices

    This paper deals with the reduction of power dissipation in the basic logic circuit like NAND gate and NOR gate by using transistor stacking technique. The logic gates are designed using 130nm technology parameter and are simulated using PSPICE. The input vector combinations are compared with the simulated result on the basis of propagation delay and power consumption. It is found that when the number of low input increases in case of NAND gate the power dissipation decreases but the delay increases and for NOR gate power dissipation decreases with the increase in high input vector combinations
