Fruit flies are causing extensive socio-economic losses in citrus orchards in Ghana. The flies as quarantine pests have detrimental effects on the export market due to international trade regulations. Oecophylla species have been tested as biological control agents on other crops, and have shown great potential in reducing the effects of pests. The effectiveness of Oecophylla as a biocontrol agent of fruit flies was compared with insecticide, cypermethrin ＋ Dimethoate （cydim super~） at Forest and Horticultural crops Research centre, Kade, in the Eastern Region of Ghana. The results have shown that trees colonized by Oecophylla had between 6%-10% fly infestation and cypermethrin ＋ Dimethoate （1614 mg a.i. mL~ tree＂1） recorded 3.0% infestation. cypermethrin ＋ Dimethoate treatment recorded 3.50 ~ 0.87 dropped fruits, and Oecophylla colonized-trees recorded 15 to 19.20 -4- 3.61. Oecophylla colonized-trees recorded yield values from 12.90 to 15.20 tons ha-~ whilst cypermethrin ＋ Dimethoate treatment recorded 27.90 tons hat fruit yield. Total number of fly landings in the presence of Oecophylla （72.00） was significantly lower than the absence of Oecophylla （114.20）. Set-up with no Oecophylla recorded the highest infestation index （71.17） while the presence recorded 45.83. These results suggest that Oecophylla longinoda can be used as a biocontrol agent for IPM programs in citrus orchards.

背景与目的利用我国现有相对较完善的肺癌发病死亡资料,描述中国肺癌死亡趋势,并估计和预测2000年及2005年的肺癌发病与死亡状况,以期对我国肺癌临床、基础研究及防治策略制定提供依据及参考.方法利用Joinpoint模型对卫生部上报WHO的中国1987～1999年肺癌死亡数据进行趋势分析,结合我国1990～1992年第二次全死因调查结果及我国入选第八卷中肿瘤登记处的肺癌发病死亡数据,采用对数线性模型(基于Poisson分布),估计并预测2000年及2005年中国肺癌的发病、死亡状况.结果我国肺癌年龄调整死亡率总体呈上升趋势,尤以农村明显(男性年均上升2.7%,女性上升3.6%,均有统计学意义)且各年龄段(15岁以上)均呈不同程度上升趋势.自2000年至2005年,我国肺癌的死亡人数将增加10.1万(自2000年的32.7万增至2005年的42.8万),发病人数将增加11.6万(自2000年的38.1万增至2005年的49.7万).结论由于肺癌危险因素变化及人口增长、老龄化的双重作用,肺癌已成为中国近年来最常见、增幅最大的恶性肿瘤之一,其预防与控制将成为未来中国肿瘤控制计划制定和实施的重点之一,而控制烟草无疑成为其关键.

HER2-Specific Vaccines for HER2-Positive Breast cancer Immunotherapy

Anti-human epidermal growth factor receptor-2 (HER2) immunization can be elicited by vaccination with DNA encoding the extra- or intra-cellular domain (EcD or IcD) of HER2, naked or encap-sulated in viral vectors. HER2-peptides derived from EcD or IcD of HER2, and HER2-pulsed dendritic cells (Dcs) or engineered Dcs expressing HER2, respectively. We performed a computer- based literature search which includes but is not limited to the following keywords: breast cancer, immunotherapy, HER2-peptide vaccine, HER2-DNA vaccine, HER-Dc vaccine, HER2 vaccine, and HER2/neu, in PubMed, Medline, EMBO and Google Scholar;data from recently reported clinical trials were also included. Drawing upon this synthesis of literature, this work summarizes the de-velopment and current trend in experimental and clinical investigations in HER2-positive breast cancer using HER2-specific vaccine and immunotherapy, focusing especially on: (i) DNA-;(ii) peptide-;and (iii) Dc-based vaccines. It addresses interventions that have been applied to overcome immunotolerance thereby to improve treatment outcomes. These include blocking the inhibitory cytotoxic T lymphocyte-associated protein-4 (cTLA-4), which is expressed at high levels by regulatory T (Treg) cells, or complete Treg depletion to improve T-cell activation. Moreover, modulatory interventions can provide further improvement in the efficacy of HER2-specific vaccine. The interventions include the use of immunogenic adjuvants such as cytokines interleukin-12 (IL-12), tumor necrosis factor (TNF)-α and granulocyte-macrophage colony-stimulating factor (GM-cSF), the use of Toll-like receptor (TLR) ligands and tetanus toxin’s universal epitopes such as the cD4+ help T (Th)-epitope P30, and the use of either chimeric or heterogenous xenogeneic HER2. combining active HER2-vaccination with adoptive trastuzumab antibody immunotherapy is likely to increase the effectiveness of each approach alone.

Effect of Nutrient Restriction on Social Transmission of Food Preferences Depends on Nutrient and Species

引用

Journal of Behavioral and Brain Science 2014年第12期4卷 590-601页

作者： Darryl J. Mayeaux maxwell B. Wallace Anne M. Young Department of Psychology St. Bonaventure University New York USA

For omnivores to determine whether an unfamiliar item is an appropriate food, they could rely on personal information from sampling it themselves or rely on less risky observation of whether other individuals eat the item. Availability of information about food from social companions in group-living species is one of the benefits of group life. Adults of solitary-living species, however, seem typically less likely to rely on social information about food choice. If an individual faced a nutritional deficit, it would seem to increase the value of public information. This study addresses whether dietary restriction from certain nutrients (sodium, potassium, protein, carbohydrates) affects reliance on information about food from conspecifics. Without nutrient restriction, group-living Norway rats (Rattus norvegicus) preferred the diet that they smelled on the breath of a conspecific demonstrator, but solitary-living Syrian hamsters (Mesocricetus auratus) avoided it. Protein restriction yielded similar results as measured one hour into a diet choice test. Potassium restriction, however, reversed the pattern: rats avoided the demonstrator’s diet but hamsters preferred it. clearly, the valence of social information depended on the nutrient from which individuals were restricted and the species under study. This could be related to the contrasting social organization that members of each species generate. Neither species relied on social information about the availability of a nutrient from which they were restricted if they could taste that nutrient for themselves (sodium, carbohydrates).

Generalized Kumaraswamy Generalized Power Gompertz Distribution: Statistical Properties, Application, and Validation Using a Modified chi-Squared Goodness of Fit Test

引用

Applied Mathematics 2022年第3期13卷 243-262页

作者： Obubu maxwell Ibeakuzie Precious Onyedikachi Khaoula Aidi chijioke Igwe Akpa Nacira Seddik-Ameur Department of Statistics Nnamdi Azikiwe University Awka Nigeria Health Systems consult Limited Abuja Nigeria Laboratory of Probability and Statistics LaPS University BadjiMokhtar Annaba Algeria Nigerian centre for Disease control Abuja Nigeria

A new six-parameter continuous distribution called the Generalized Kumaraswamy Generalized Power Gompertz (GKGPG) distribution is proposed in this study, a graphical illustration of the probability density function and cumulative distribution function is presented. The statistical features of the Generalized Kumaraswamy Generalized Power Gompertz distribution are systematically derived and adequately studied. The estimation of the model parameters in the absence of censoring and under-right censoring is performed using the method of maximum likelihood. The test statistic for right-censored data, criteria test for GKGPG distribution, estimated matrix Ŵ, Ĉ, and Ĝ, criteria test Y2n, alongside the quadratic form of the test statistic is derived. Mean simulated values of maximum likelihood estimates and their corresponding square mean errors are presented and confirmed to agree closely with the true parameter values. Simulated levels of significance for Y2n (γ) test for the GKGPG model against their theoretical values were recorded. We conclude that the null hypothesis for which simulated samples are fitted by GKGPG distribution is widely validated for the different levels of significance considered. From the summary of the results of the strength of a specific type of braided cord dataset on the GKGPG model, it is observed that the proposed GKGPG model fits the data set for a significance level ε = 0.05.
