    ABSTRACT:

    To evaluate the antioxidant and antiinflammatory effects of methanolic leaf extract of the traditional medicinal plant, Cryptolepis grandiflora. The plant leaves were subjected to solvent extraction by using methanol for obtaining crude extract. The crude extract (9.12g/ml) was tested for assaying antioxidant properties by total antioxidant (ABTS•+), DPPH•, reducing power and metal chelating activities. In addition, inhibition of protein denaturation, proteinase activity and the levels of enzymic antioxidants viz., SOD, CAT and GPx were employed to determine antiinflammatory activity. Methanolic leaf extract was determined to have stronger antioxidant activity by ABTS (2321.4±397.9 μmol TE/g extract), DPPH (35.21% - 50 µg/mL and 74.37% - 250 µg/mL and IC50 - 92μg/mL), reducing power (0.231 - 300µg/mL 0.843 - 700µg/mL) and metal chelating (20.18% - 500µg/mL and 52.03% - 900µg/mL) assays in comparison to respective standards. In antiinflammatory study, protein denatturation (91.21% - 200 µg/mL and 93.12% - 400µg/mL), proteinase inhibition (90.02% – 200 µg/mL and 87.12% - 400 µg/mL) and the enzymic antioxidants viz., SOD, CAT and GPx were found to be significantly reduced (p<0.05) the inflammation in animal model. The leaves of Cryptolepis grandiflora is a potential antioxidant and antiinflammatory agent.

    ABSTRACT:

    A numerical model is developed to predict the material deformations and temperature histories in the friction stir welding (FSW) process. Based on the numerical ananlysis, the effects of the welding parameters on material deformation and temperatures are investigated for plain cylindrical and drill tool geometries. A numerical result predicts that the temperature can be increased with the increase of the rotating speed on the FSW process. In the same way the increase in the weld speed can also lead to the tangible increase of the input power. When the rotating speed becomes higher, the welding speed must be increased simultaneously to avoid any possible welding defect. The model shows that the heat is generated on the regions of the shoulder, lateral surface of pin and tip of the pin. The predicted high temperature exists on the shoulder surface. The temperature varation is analysed for the three different tool geometries and base metals using ANSYS 14. The temperature field and predicted by the simulation method are in good agreement with the results obtained by the ANSYS 14. As per the deformation analysis during the first impact of pin the drill tool geometry obviously got more deformation and there by results in increment of total heat flux.

    ABSTRACT:

    Background: Location of hinge axis and its precise transfer to the articulator where the occlusal rehabilitation is planned is a vital therapeutic protocol in fixed prosthodontics. However, there is an uncertainty regarding the effectiveness of the arbitrary or true hinge axis transfer influencing the therapeutic outcome of occlusal harmony provided by restorations, whichneeds to be investigated further in detail. Aim: To evaluate occlusal discrepancies arising after mounting with arbitrary and kinematic facebows in fixed restorations. Materials and methodology: An electronic search was initiated on the PubMed, Medline, Google Scholar data bases for articles discussing the above mentioned aim, listed in the databases till 31st December 2015. Suitable MeSH terms and key word search was initiated with Boolean operators and articles were selected. Data extraction was done from the articles satisfying the inclusion and exclusion criteria and subjected to statistical analysis. Results: The search methodology identified 13 studies out of which five studies fulfilled inclusion criteria and were included in this review. Comprehensive analysis after data extraction revealed significant heterogeneity among the included studies over the outcome variables and so a meta-analysis could not be performed. All the included studies favour the use of kinematic face bow transfer to minimize occlusal errors with a significant statistical difference (p<.05) over arbitrary facebow transfer. Conclusion: Kinematic face bow transfer is more effective than arbitrary face bow transfer in minimizing occlusal errors in fixed restorations.

    ABSTRACT:

    This study aims to determine whether micro-enterprises such as street vendors have administrative knowledge to overcome challenges associated with the government requirements. A questionnaire was administered to street vendors around the Johannesburg area to fulfil aims of this study. Descriptive results reveal a significant number of street vendors would abandon their current economic activity for jobs that pay at least US$200 a week; most street vendors have below high school education; and the vast majority of street vendors do not have any business administrative training. Inferential results reveal that government policies on micro-enterprises are almost unknown to street vendors; government laws on micro-enterprises are perceived as an impediment to street vending; andlaw enforcement agencies on micro-enterprise are perceived as hindering street vending. This study contributes to the understanding of fissures in the dissemination of government requirements to street vendors; and the comprehension of cracks in channels available to influence government policies, laws, and practice in favour of street vendors. Accordingly, there is a need for government to socialize street vendors (not through law enforcement) about policies, laws, and practices that nurture micro-enterprises

    ABSTRACT:

    Cancer is the third leading risk for global deaths. At least 2.8 million adults die each year as a result of being cancer victim. World Health Organization (WHO) further projected that by 2015 approximately 700 million individuals, both young adult males and females were survivor of cancer. Cancer is a condition that results from proliferation and abnormal division of body cells, which interferes with proper functioning of the body and has undesirable systematic effects. Although cancer is a condition or a disease which cannot be cured by diet. Drugs, chemotherapy, radiotherapy and removal of cancerous cells from the body through surgery play an important role in treatment of an individual suffering from the disease. But as a result of these drugs, the body of the suffering patient gets totally deteriorated; let it be in terms of immunity, body fatigue, and energy or food intake. Thus, to prevent and cure such side effects to an extent, it is of utmost importance to keep the patient nutritionally fulfilled. This goal can be only achieved by supplying the patient with every nutrient (carbohydrates, proteins, fats, vitamins, minerals) through diet. The present study was carried out on fifty women of age 35 – 45 years who were suffering from cervix cancer belonging to region of Delhi – NCR. The dietary history subjects were calculated by seven day recall method. Then the General Information and Medical history of the subjects was collected by interview cum questionnaire method. The causes of cervix cancer were found by questionnaire method. The nutritional education was imparted to patients to lessen the side effects of treatment.

    ABSTRACT:

    BACKGROUND: Dental impaction is defined as cessation of eruption of a tooth caused by a clinical or radio graphically detectable physical barrier in the path of eruption or due to ectopic position of the tooth in the jaw. The aim of this study is to assess the pathologies anomalies associated with impacted third molars and is to enlighten the Dental practitioners about the possible pathologies anomalies that might occur associated with impacted third molars so that these problems could be anticipated and detected earlier for a better quality of treatment and prognosis. It also emphasizes on the necessity to extract impacted third molars as soon as they are diagnosed rather than waiting for the symptoms to arise because by the time the symptoms arise, pathological changes would have already set in. MATERIALS AND METHOD: 100 OPGs of patients with impacted tooth/teeth were collected. The OPGs are of patients from different age groups and these are randomised samples. The subjects of the study are out patients of Saveetha Dental College and the patients' radiographs were taken at the same place. RESULTS: Among the 100 OPGs of patients with one or more impacted teeth, it was found that in 51 cases mandibular right third molar(48) was impacted which had the highest occurrence of impaction. Out of 100 cases, 82 cases had radiographic findings associated with the impacted teeth. Incidence of bone loss was found to be highest among the impacted third molars which was 55%. The major pathologies like ameloblastoma and dentigerous cyst was found in 3% which had the least incidence. CONCLUSION: Considering the problems associated with impacted third molars as observed during the study, retention of such impacted teeth may cause serious pathologies and may increase the risk of postoperative complications. Hence it is advisable to treat impactions at an early stage through prompt diagnosis and explaining the patient regarding such complications. And removal of impacted third molars, whether symptomatic or asymptomatic is recommended as early diagnosis may prevent the onset of pathologies.

    ABSTRACT:

    Saliva constitutes an important role in maintaining the health of the oral cavity. It helps in lubrication, mastication, and has effective antimicrobial action. In prosthodontics, saliva plays a main role in retention of the denture. Hyposalivation is a main complication in diabetes, radiotherapy, chemotherapy, sjogren syndrome, certain systemic conditions and patients with maxillofacial defects. Pharmacotherapy is the initial management to increase the salivary flow. Cholinergic drugs are administrated systemically to increase the salivary flow. However, in extreme cases salivary substitutes are used to maintain and increase the salivary flow. This article is about the role of salivary substitutes to modulate salivary flow to enhance prosthodontic success.

    ABSTRACT:

    Increased industrialization and ever growing consumerism has led to a situation where industrial pursuits of mankind have started to cast an unfavorable impact on environment that may prove self-destructive for the future. Earlier Developed countries, in their pursuit of economic development and progression to their current economic status, showed little respect for environmental concerns. But as on today, there is an increased awareness on part of their industries, governments and even consumers for conserving environment and cutting down on pollution. Nevertheless, it is just a beginning and there is a long, long-way to go. The growing awareness for environmental concerns led to adoption of Green marketing practices, which though, of relatively recent origin has gained worldwide popularity and recognition in a brief time period. In Indian Perspective, during the last few years, hundreds of studies have been carried out on the subject, addressing the various facets of the concept. Thus the purpose of this paper is to understand the perception of industries in India towards green marketing practices- a fast growing economy, towards green philosophy and to investigate further what initiatives those industries have taken for becoming green. To create a sustainable environment, the aim of this study is to explore and identify the components of environmental attitude that can drive the specific ecological behavior of Indian organizations. Most of the industries had the perception that Adopting green marketing practices would ensure them competitive advantage over their competitors. Therefore, these days’ concepts of green marketing are taking shape as one of the key business practices of the companies for gaining the competitive advantage, ensuring sustainability. This research is a step to fill up this gap. The findings of the study demonstrate that these days’ industries are having high concern about environmental protection and are willing to produce those products which are environmentally friendly i.e. green in nature. The companies who offer green products will definitely enjoy a competitive advantage over their competitors.
