    We have studied the potential of the CDF and DZero experiments to discover a low-mass Standard Model Higgs boson, during Run II, via the processes ppˉp\bar{p} -> WH -> ℓνbbˉ\ell\nu b\bar{b}, ppˉp\bar{p} -> ZH -> ℓ+ℓ−bbˉ\ell^{+}\ell^{-}b\bar{b} and ppˉp\bar{p} -> ZH ->ννˉbbˉ\nu \bar{\nu} b\bar{b}. We show that a multivariate analysis using neural networks, that exploits all the information contained within a set of event variables, leads to a significant reduction, with respect to {\em any} equivalent conventional analysis, in the integrated luminosity required to find a Standard Model Higgs boson in the mass range 90 GeV/c**2 < M_H < 130 GeV/c**2. The luminosity reduction is sufficient to bring the discovery of the Higgs boson within reach of the Tevatron experiments, given the anticipated integrated luminosities of Run II, whose scope has recently been expanded.Comment: 26 pages, 8 figures, 7 tables, to appear in Physical Review D, Minor fixes and revision

    Objective: To investigate the presence of phytochemical components and to evaluate the in vitro antioxidant activity of pet. ether, chloroform, methanol and aqueous extracts of Grewia heterotricha mast leaves.Methods: The leaves of Grewia heterotricha mast were dried and extracts were prepared using a pet. ether, chloroform, methanol by soxhlet extraction method. The aqueous extract was prepared using distilled water by cold extraction method. The preliminary phytochemical analysis was carried out on aqueous, methanol, chloroform and pet. either leaf extracts of the plant using standard qualitative procedures. The total phenolic content (TPC) was estimated using modified Folin-Ciocalteau method, tannin content by Folin-Denis method and total flavonoids by aluminum chloride method. In vitro, antioxidant activities were evaluated by 1,1-Diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, H2O2 scavenging activity and FRAP assay.Results: The preliminary phytochemical analysis revealed the presence of complex bioactive constituents like phenols, tannins, alkaloids, terpenoids, flavonoids, saponins, steroids, glycosides, coumarins, proteins and carbohydrates. Methanolic extract showed highest total phenolic content (87.58±2.52 mg CE/g) than aqueous extract (78.46±5.36 mg CE/g). Higher tannin content was found in the aqueous extract (148.0±8.96 mg TAE/g). Total flavonoids were highest in chloroform extract (314.9±25.06 mg QE/g) followed by aqueous (242.98±32.42 mg QE/g) and methanolic extract (217.0±18.32 mg QE/g) and lowest in a pet. ether extract (188.86±23.35 mg QE/g). The methanolic extract had shown very significant DPPH radical scavenging activity (IC50 98.95 µg/ml) and H2O2 scavenging activity (IC50110.1µg/ml) compared to the standard ascorbic acid. Higher reducing ability was observed in methanol extract (131.8±11.67 mg AE/g).Conclusion: The results obtained reveal that the leaves of Grewia heterotricha mast have potent antioxidant property. The observed activity may be associated with bioactive components like phenolics, flavonoids present in the leaf extracts and could have greater importance as therapeutic agents in oxidative stress-related degenerative diseases. Further studies are needed in order to purify bioactive compounds responsible for the antioxidant property

    World Health Organization defines the health as a State of physical, psychological, social and spiritual wellbeing, not merely the absence of disease, the same thought of holistic approach of health conceived some centuries ago by the oriental intellectuals especially Ayurvedic classics with the beautiful definition : Samadosha samagnicha samadhatu malakriya, Prasannathmendriya mana: swasthaithiabhidheeyate†which shows the in depth foresight towards physiological as well as psychological state in maintaining the positive health. The mental equilibrium is also needed for conception (Garbhavakranti), development of the foetus (Garbhavridhi).The present paper attempts to analyze and establish the role of Mano samyata in Garbhavakranti (conception), Garbhinicharya (antenatal care) and Garbhavridhi (fetal development) through the immune –Nervous –Endocrine orchestra

    Episiotomy procedure is introduced in obstetrical practice more than 200 years ago but is put in frequent practice in the 20th century. Postnatal complications were more common among women who had episiotomy compared to those who did not have episiotomy; hence postpartum care of episiotomy wound should begin as soon as possible. So the present study has been done on episiotomy wound healing. Basically two things Shodhana (cleaning) and Ropana (healing) are desirable for proper healing. Many single drugs and compound formulations have been described in the classics for wound healing. The present study is taken up with the aim of comparison of clinical evaluation of wound healing property of Nimbadi and Yastyadi ointment, topical application on episiotomy wound. Study carried out on total 30 patients, under group A 15 patients treated with Nimbadi ointment, and 15 patients in group B treated with Yastyadi ointment. Both Groups were given local application of ointment on episiotomy wound as per requirement twice a day for a period of 14 days. On observation Group A therapy shows 66.62 % relief in signs and symptoms of wound along with good status of healing (cured) i.e. 53.33%. Group B therapy shows 49.50% relief in signs and symptoms of wound along with average status of healing (Partially cured) i.e. 46.66%. Better result was observed in group A in comparison to group B. No adverse effect was observed in any patient during the trial

    Inability of a couple to achieve conception after one year of unprotected coitus is defined as infertility. Fecundability starts to decline from early thirties and accelerates during the late thirties and early forties. Achievement of conception depends on the fertility capacity of both the male and female partner; male is directly responsible in around 30% of cases, female in 30% and both are responsible for 30% of cases, and in the remaining 10% of cases cause remains unexplained. In the existing modern system of medicine, there is no proper intervention available to clear the tubal block. In Ayurveda, Uttaravasti and Yonipichu like direct solutions are available to deliver the drug in-situ in the uterus. Present study is reporting of a case of fallopian tubal block treated with Dhanvantaram oil Uttaravasti as well as Yonipichu (vaginal tampon). Unilateral tubal block was successfully cured with this trail drug and drug delivery methods

    Polycystic ovarian disease is one of the most common gynecological disorders during puberty. This is otherwise known as Stein-Leventhal Syndrome and occurs due to the incorrect set of hypothalamo-pituitary homeostatic during puberty and characterized by oligomenorrhoea / amenorrhoea, delayed periods, hirsutism, hoarseness of voice etc. Based on the clinical features this can be compared with Alpartava /Artavakshaya as per the Ayurvedic classics. In Artavakshaya (deficiency of Artva), Rajasrava (menstruation) do not appear in its appropriate time or is delayed. Often gynecologists keep these patients on combination of estrogen and progesterone therapy. Exogenous hormonal treatment again disturbs the endogenous hormonal pattern and the pathology continues. In the present study an attempt has been made to find out safe alternate therapy to cure PCOD and regularize menstruation with Ayurvedic drugs. For the present study, Ashokarishtam is selected to improve Rajodhatu, Kanchanara guggulu and Varunadi kashayam are selected to regress cysts of the ovary. Study carried out in 52 number of teenage girls, out of which, 21 (42.86%) patients have shown Good Response, 10 (20.41%) cases have shown Fair response, 03 (06.12%) cases have shown Poor response, 15 (32.61%) did not show any response and 03 cases were dropped out from the study. On statistical analysis, efficacy of the trial drugs found highly significant in relieving PCOD (P&lt;0.001)

    \ua9 Journal of Krishna Institute of Medical Sciences University.Background: Over recent years, wide-ranging changes have occurred in undergraduate medical curricula with reduced hours allocated for teaching anatomy. Anatomy forms the foundation of clinical practice. However, the challenge of acquiring sufficient anatomical knowledge in undergraduate medical education for safe and competent clinical practice remains. Assessment is an essential component of the teaching and learning process and is more important than teaching methods. It is essential to assess anatomy competencies for competent clinical practice. A single tool is not sufficient to assess anatomy competencies, so multiple methods are employed to assess anatomy in Competency-based Medical Education (CBME). Aim and Objectives: The present study was undertaken to identify the most appropriate tools to assess anatomy competencies in CBME curriculum. Material and Methods: A modified Delphi technique with three rounds involving twenty renowned anatomists across the country was conducted. Anatomy assessment tools were generated from the opinions of this expert panel in the first round. The relevance of these tools was rated with a five-point Likert scale in the subsequent two rounds to generate consensus. Results: Response rates were 80% for the first round and 100% for the next two rounds. After three Delphi rounds, seven assessment tools were identified as the most valuable following iterations. Conclusion: The findings of this study provide anatomists with the current required essential tools for assessing anatomy competencies of higher-order cognitive domains and psychomotor domains for the CBME curriculum
