Minimization of Collision in Energy Constrained Wireless Sensor Network

Wireless Sensor Network 2009年第4期1卷 350-357页

作者： Moses Nesa sudha Muniappan Lakshapalam VALARMATHI George RAJSEKAR Michael Kurien MATHEW Nagarajan DINESHRAJ Sivasankaran RAJBARATH 不详

Wireless Sensor Networks (WSNs) are one of the fastest growing and emerging technologies in the field of Wireless Networking today. The applications of WSNs are extensively spread over areas like Military, En-vironment, Health Care, Communication and many more. These networks are powered by batteries and hence energy optimization is a major concern. One of the factors that reduce the energy efficiency of the WSN is collision which occurs due to the high density of data packets in a typical communication channel. This paper aims at minimizing the effects of congestion leading to collision in the network by proposing an effective algorithm. This can be done by optimizing the size of the contention window by introducing pa-rameters like source count and α. If the contention window of a node is low, it results in collision. If the size of the contention window of a node is high then it results in a medium access delay. Thus minimizing colli-sion and medium access delay of data packets conserve energy.

Aging is the leading risk factor for neurodegenerative diseases and oxidative stress involved in the pathophysiology of these diseases. These changes increase during menopausal condition in females when the level of estradiol is decreased. The aim of the present study was to determine the effect of tachykinin neuropeptide, Neurokinin B (NKB) and Amyloid beta fragment Aβ (25 -?35) on 17β estradiol (E2) treated aging female rat synaptosomes of different age groups. Aging brain functions were assayed by measuring the activities of antioxidant enzymes—superoxide dismutase (SOD) and monoamine oxidase (MAO) with neuropeptides. An in-vitro incubation of Aβ (25 -?35) in E2 treated brain synaptosomes showed toxic effects on all the parameters. However, NKB and NKB combined with Aβ (25 35) showed stimulating effects in E2 treated rat brain synaptosomes. In the present study, an increase in activity of SOD and decrease in the level of MAO, in the presence of NKB and combined NKB and Aβ in E2 treated brain synaptosomes of aging rats. This study elucidates that treatment of NKB and Aβ with E2 incombination exerts more protective influence than their individual application, against excitotoxicity in age related changes.

Neuroprotective role of 17βestradiol with tachykinin neuropeptide NKB and Aβ(25 - 35) in aging female rat brain

引用

Advances in Aging Research 2013年第4期2卷 130-136页

The brain experiences structural, molecular and functional alterations during aging. In aging brain tissue, the oxidative stress increases due to decreased activity of antioxidant enzymes and increased oxidative stress leading to neurodegeneration associated with excitotoxicity. In the present study, we observed the effect of tachykinin neuropeptide Neurokinin B (NKB) and amyloid beta fragment Aβ (25 -?35) on the activity of Acetylcholine esterase (AChE) and Lipid peroxidation (LPO) in brains of 17β estradiol (E2) treated aging female rat synaptosomes of different age groups. An in-vitro incubation of E2 treated brain synaptosomes with Aβ (25 -?35) showed toxic effects on all the parameters. The treatment of NKB and combined NKB and Aβ (25 -?35) increased the AChE enzyme activity and decreased the level of LPO in E2 treated aging rats. The treatment of NKB and combined NKB and Aβ (25 - 35) in a concentration dependent manner reversed the effects of aging and Aβ (25 -?35) on AChE and LPO. The present finding suggests that E2 along with NKB reverse aging and Aβ (25 -?35) induced toxicity as well as AChE and LPO levels. The results of the current study showed a possible beneficial role of NKB with E2 inthe age related neurological diseases.

Efficacy of Whole Blood Reconstituted (WBR) in Exchange Transfusion (ET) in Hemolytic Disease of New Born (HDN) —A Study of 110 Cases

Open Journal of Blood Diseases 2013年第1期3卷 15-20页

Aim: This study was aimed to review and establish the practice of exchange transfusion (ET) with whole blood reconstituted (WBR) in hemolytic disease of newborn (HDN). Objectives: To observe fall in indirect serum bilirubin, correction of anemia and comparison with related studies. Background: Hemolytic disease of the Newborn is characterized by presence of IgG antibodies in maternal circulation, which causes hemolysis in the fetus by crossing the placenta and sensitizing red cells for destruction by macrophages in the fetal spleen with consequent hyperbilirubinemia. Exchange transfusion with or without phototherapy is the method of choice for treating the newborn with on going hemolysis Methods/Materials: Sample size consisted of 110 neonates in whom 119 exchange transfusions were carried out with WBR. WBR was prepared by suspending O Rhesus-D (RhD) positive/negative cells (compatible with neonate’s/ mother’s serum) in AB plasma. Double volume exchange transfusion(s) were carried out through umbilical vein by push-pull technique. Results: Out of 110 cases, 61 (55.5%) were of RhD HDN whereas ABO and other group HDN cases were 30 (27.3%) and 19 (17.3%) respectively. An average post-ET fall in indirect serum bilirubin by 54.6% and correction of anemia by3.7 gm/dl were reported in the study. Conclusion: An average post-ET fall in indirect serum bilirubin and correction of anemia was found to be more significant when compared to other studies. Hence we recommend exchange transfusion in HDN with WBR to obtain reasonable fall in indirect serum bilirubin and high average rate of correction of anemia.

越来越多的研究提出，肺部非典型腺瘤性增生（atypical adenomatous hyperplasia,AAH)可能是肺腺癌的前兆。世界卫生组织现在已承认AAH的存在，并指出，AAH可能不易与非粘液型细支气管肺泡癌鉴别，令人遗憾的是，目前尚无普遍认同的诊断AAH的形态学标准，本文综述探讨了AAH的流行病学、大体外观，光镜下所见，形态测量，免疫组化和分子学特征，并提出一系列组织病理学特征，从而可能有助于临床病理医师识别这种诡异的病变，这些特征包括：沿肺泡框架扩散的局灶性不典型细胞增生，增生灶边缘不规则；细胞为立方至低柱状肺泡细胞，呈不同程度的不典型性，但不如在腺癌中见到的不典型严重，细胞体积和核－浆比增加，核深染和有明显的核仁，通常不典型细胞间连接完整，偶在这些细胞之间见有空隙，细胞构成不增多，也不成簇或呈乳头状结构；被AAH细胞散布的肺泡壁轻微增厚，有一些纤维组织增生，但无瘢痕形成，周围肺细胞也无明显的慢性炎症，有些研究指出，AAH是一种与肺腺癌密切相关的病变，认为AAH可能是复杂的肺腺癌多步骤癌变过程的早期。
