Objective: To determine the relationship between C-reactive protein(CRP) level and the severity of dengue and the potential use of CRP in predicting acute dengue ***: A prospective observational study was performed on dengue patients admitted to a tertiary care hospital in southern India. All patients of age above 18 years, diagnosed with dengue were included in the study. The detailed laboratory parameters pertaining to dengue were recorded. CRP levels were estimated and compared between groups i.e. severe and non-severe dengue. CRP cut-off value was detected using the receiver-operator ***: Totally 98 patients with a mean age of 40 years were included. Among them, 11.2% of the patients suffered from severe dengue, 54.1% of the cases had non-severe dengue without warning signs, and 34.7% had non-severe dengue with warning signs. The median CRP was significantly higher in patients with severe dengue compared to patients with non-severe dengue(96.2 mg/d L vs. 5.3 mg/d L). Univariate logistic regression analysis showed that the odd’s ratio(OR) of CRP was 1.053(P≤0.001, 95% CI=1.029-1.078). CRP at a cutoff value of 21.6 mg/L(0.929 AUC) had excellent sensitivity(100%) and specificity(81.6%) in predicting severe dengue infection. Multivariate logistic regression analysis showed that CRP(OR=1.089, P=0.013) and ALT(OR=1.010, P=0.034) were statistically significant independent predictors of dengue ***: CRP level could be used as a potential biomarker to predict severity of dengue in adults.

Long-term effects of management systems on crop yield and soil physical properties of semi-arid tropics of Vertisols

Agricultural Sciences 2011年第4期2卷 435-442页

作者： Prabhakar Pathak Suhas P Wani raghavendra rao Sudi 不详

Long-term experiments can be used to assess management induced changes in soil properties and sustainability of the management system in terms of the productivity. Such data are scanty, especially in the semi-arid tropics (SAT) region. A long-term experiment established in 1976 at ICRISAT in India on Vertisols with two management treatments;improved management (IM), comprising semi-permanent broadbed and furrow (BBF) landform with minimum tillage and improved cropping practices;and traditional management (TM) system comprising keeping the land fallow during the rainy season and sowing on flat landform during post-rainy season with traditional cropping practices, was sampled after 24 and 34 years for soil physical and hydrological properties. Results showed that both in short-and long-term the management systems had profound effect on crop yields. Also in the long-term IM and TM management systems had significant effect on several soil physical and hydrological properties. Throughout the soil profile IM systems had significantly lower bulk density, significantly higher porosity, substantially lower penetration resistance both at 5 cm (1 and 8 MPa) and 15 cm depths (8 and 15 MPa), significantly higher infiltration and sorptivity and significantly larger mean weight diameter of 4.3 mm compared to 2.8 mm for soils under TM. However, management systems had no significant effect on moisture holding capacities both at 0.033 and 1.5 MPa. Significant differences between the improved and traditional systems were observed in the size and pattern of soil surface cracks. Over the long-term, the improved management systems has very favorable effects on soil physical and hydrological properties and on the soil surface cracking and its patterns, thereby contributing to higher productivity.

Journal of Cancer Therapy 2017年第9期8卷 838-844页

Background: Lung cancer is the leading cause of cancer-related death worldwide with an estimated 1.6 million new cases diagnosed each year. According to standard guidelines in NSCLC, the effectiveness of combined chemotherapy regimen comprises of pemetrexed and platinum, and very few reports are available in Indian population. This study shows the experience with pemetrexed and platinum combination chemotherapy in metastatic NSCLC in first line setting. Methods: Total 61 patients with following inclusion criteria were recruited such as: 1) PS of 1 and 2;2) NSCLC of non-squamous histology;3) locally advanced or metastatic disease at diagnosis;4) should have received minimum 3 cycles of pemetrexed and platinum as first line treatment and or continued for 6 cycles;5) EGFR/ALK mutated or EGFR/ALK unknown patients but must have received upfront chemo. Primary endpoint of the present study is to assess Disease Control Rate (DCR) (CR + PR + SD). Progression Free Survival, OS and Toxicity assessment were secondary endpoints. Results: The mean number of average chemotherapy cycles was found to be 4.38. The range of chemotherapy was 2 - 6 cycles. Disease control rate, defined as (CR + PR + SD), was seen in 44 (72.1%) patients. (PR in 26 (42.62%), SD 18 (29.5%)), Progressive disease (PD) was observed in 17 (27.9%) patients. Overall study showed that patients had PFS of 9.414 months (95% CI 6.709 - 12.120) and OS of 13.437 months (95% CI 10.721 - 16.153). Conclusion: Pemetrexed and platinum combination is effective and well-tolerated chemotherapy regimen in patients with metastatic adenocarcinoma lung cancer patients. Pemetrexed and cisplatin may be more effective in particular. Early switch over to TKIs is preferred immediately after obtaining molecular subtype result.

Multimodal Biometric Score Fusion Using Gaussian Mixture Model and Monte Carlo Method

引用

Journal of Computer Science & Technology 2010年第4期25卷 771-782页

作者： R raghavendra rao Ashok G Hemantha Kumar Department of Studies in Computer Science University of Mysore Department of E&C Channabasaveshwara Institute of Technology

Multimodal biometric fusion is gaining more attention among researchers in recent days. As multimodal biometric system consolidates the information from multiple biometric sources, the effective fusion of information obtained at score level is a challenging task. In this paper, we propose a framework for optimal fusion of match scores based on Gaussian Mixture Mode] （GMM） and Monte Carlo sampling based hypothesis testing. The proposed fusion approach has the ability to handle： 1） small size of match scores as is more commonly encountered in biometric fusion, and 2） arbitrary distribution of match scores which is more pronounced when discrete scores and multimodal features are present. The proposed fusion scheme is compared with well established schemes such as Likelihood Ratio （LR） method and weighted SUM rule. Extensive experiments carried out on five different multimodal biometric databases indicate that the proposed fusion scheme achieves higher performance as compared with other contemporary state of art fusion techniques.
