This paper proposes an improved sine-cosine algorithm(ISCA)based 2-DOF-PID controller for load frequency control.A three-area test system is built for study,while some physical constraints(nonlinearities)are considered for the investigation of a realistic power *** proposed method is used as the parameter optimizer of the LFC control-ler in different *** 2-DOF-PID controllers are used because of their capability of fast disturbance rejection without significant increase of overshoot in set-point *** 2-DOF-PID controllers’efficacy is observed by examining the responses with the outcomes obtained with PID and FOPID *** simulation results with the suggested scheme are correlated with some of the existing algorithms,such as SCA,SSA,ALO,and PSO in three dif-ferent scenarios,i.e.,a disturbance in two areas,in three areas,and in the presence of physical *** addition,the study is extended to a four-area power *** analysis is performed using the Wilcoxon Sign Rank Test(WSRT)on 20 independent *** confirms the supremacy of the proposed method.

Objective:To evaluate the wound healing effect of aqueous extract of Crotalaria verrucosa(C. verrucosa) in ***:Three wound models including incision,excision and dead space wounds were used in this *** parameters studied were breaking strength in incision models,granulation tissue dry weight,breaking strength and hydroxyproline content in dead space wounds,percentage of wound contraction and period of epithelialization in excision wound ***:Two doses of the extract with and without dexamethasone showed significant increases in mean hydroxyproline,total protein content and dry weight of granulation tissue but it was higher with dose 800 mg/kg comparing with the *** dexamethasone treated group showed a significant(P<0.001) reduction in the wound breaking strength when compared to control group in incision type of wound *** of *** with dexamethasone significantly(P<0.001) increased the breaking strength compared to the dexamethasone treated only *** excision wound model,the percentage of the wound contraction was significantly(P<0.01) increased by two doses of test extract on all the days except the lower dose which exhibited only on 12th,16th days of drug treatment and it also reversed the dexamethasone suppressed wound *** significantly(P<0.001) reduced the time required for epithelialization and reversed the epithelialization delaying effect of dexamethasone (P<0.001).Conclusions:*** was found to possess significant wound healing property. This was evident by decrease in the period of epithelialization,increase in the rate of wound contraction,skin breaking strength,and granulation tissue dry weight *** C. verrucosa could be a good wound healing agent.

Wogonin is a plant flavonoid compound extracted from Scutellaria baicalensis(Huang-Qin or Chinese skullcap) and has been studied thoroughly by many researchers till date for its anti-viral, anti-oxidant, anti-cancerous and neuro-protective properties. Numerous experiments conducted in vitro and in vivo have demonstrated wogonin's excellent tumor inhibitory properties. The anticancer mechanism of wogonin has been ascribed to modulation of various cell signaling pathways, including serine-threonine kinase Akt(also known as protein kinase B) and AMP-activated protein kinase(AMPK) pathways, p53-dependent/independent apoptosis, and inhibition of telomerase activity. Furthermore, wogonin also decreases DNA adduct formation with a carcinogenic compound 2-Aminofluorene and inhibits growth of drug resistant malignant cells and their migration and metastasis, without any side effects. Recently, newly synthesized wogonin derivatives have been developed with impressive anti-tumor activity. This review is the succinct appraisal of the pertinent articles on the mechanisms of anti-tumor properties of wogonin. We also summarize the potential of wogonin and its derivatives used alone or as an adjunct therapy for cancer treatment. Furthermore, pharmacokinetics and side effects of wogonin and its analogues have also been discussed.

Diabetes is a chronic metabolic disease reaching an epidemic proportion in many parts of the world. By the year 2025 it is expected that 333 million people of the world will have diabetes as their main ailment. As today, India assumes the position of the diabetic capital of the world with the highest percentage of its population suffering from diabetes. It is pathetic to mention that in proportion to its people suffering from diabetes, this country has very weak spending power for treatment because of wide spread poverty. Therefore, this review is aimed at opening up new vistas in realizing the therapeutic potential of Ayurveda in treatment of diabetes and other chronic diseases. All drugs which we have discussed in this review have a significant role in therapy of diabetes mellitus.

目的借助于哮喘控制测试(ACT),论证使用吸入型糖皮质激素作为控制哮喘患者病情的临床疗效,与未使用任何药物控制哮喘症状或疾病发作的患者进行数据比较。方法在2012年7月,总共60名哮喘患者被要求做ACT问卷,其中32名患者作为对照组(n=32)未使用任何控制药物;28名患者作为观察组(n=28)使用吸入型糖皮质激素;并对两组的ACT结果进行了比较。结果所有患者都进行了ACT,并得到了相应的ACT分值。在对照组中,所有男性(n=13)患者的哮喘病情都控制不佳,19名女性中只有2名(10.53%)患者的病情得到了轻微的控制,其余的17名女性患者(89.47%)哮喘病情都控制不佳。在观察组中,男性患者(n=13)有6名(46.15%)患者哮喘病情未得到控制,女性患者(n=15)中,只有3名(20%)患者哮喘病情未得到控制。总体来说,ACT分值高于19的情况下,11名(39.29%)患者的哮喘得到了良好控制。结论使用吸入型糖皮质激素的哮喘控制物,例如倍氯米松和去炎松在维持哮喘的良好控制方面取得较好结果 ,ACT分值结果展示了这一点。使用吸入型糖皮质激素与未使用任何控制物相比,ACT分值得到了显著改变。
