Abstract: Controlled release local drug delivery systems offer advantages compared to systemic dosage forms for periodontitis. The objective of this research was to design and evaluate sustained release dental films containing lomefloxacin hydrochloride in a non-biodegradable carrier for targeted delivery of drug. Polymer ethyl cellulose was used in the formulation of the dental films. The dental film was then evaluated for various parameters and in-vitro, in-vivo study. The effects of various formulation variables on the drug release profiles from the films were studied to determine optimum formulations. Drug release profile of dental film showed that the film exerted an initial burst release followed by sustained release of the drug and the drug release was well above the minimum inhibitory concentration throughout the time of study. The study suggests that non-biodegradable polymer based dental film of lomefloxacin hydrochloride is a potential local drug delivery device for the treatment of periodontitis.
Cardiovascular Responses Associated with Daily Walking in Subacute Stroke

Stroke Research and Treatment , 2013, DOI: 10.1155/2013/612458
Abstract: Despite the importance of regaining independent ambulation after stroke, the amount of daily walking completed during in-patient rehabilitation is low. The purpose of this study is to determine if (1) walking-related heart rate responses reached the minimum intensity necessary for therapeutic aerobic exercise (40%–60% heart rate reserve) or (2) heart rate responses during bouts of walking revealed excessive workload that may limit walking (>80% heart rate reserve). Eight individuals with subacute stroke attending in-patient rehabilitation were recruited. Participants wore heart rate monitors and accelerometers during a typical rehabilitation day. Walking-related changes in heart rate and walking bout duration were determined. Patients did not meet the minimum cumulative requirements of walking intensity (>40% heart rate reserve) and duration (>10?minutes continuously) necessary for cardiorespiratory benefit. Only one patient exceeded 80% heart rate reserve. The absence of significant increases in heart rate associated with walking reveals that patients chose to walk at speeds well below a level that has meaningful cardiorespiratory health benefits. Additionally, cardiorespiratory workload is unlikely to limit participation in walking. Measurement of heart rate and walking during in-patient rehabilitation may be a useful approach to encourage patients to increase the overall physical activity and to help facilitate recovery. 1. Background Regaining independent ambulation is important to those with stroke [1, 2] and is the most frequently reported rehabilitation goal [3, 4]. Therefore, walking should be an integral part of in-patient rehabilitation. However, accelerometer-based monitoring of walking activity has revealed that the amount of daily walking completed by individuals with stroke during in-patient rehabilitation is low [5, 6]. Importantly, the majority of walking bouts are of short duration (<1 minute) [5–7] and typically involve walking to essential activities (e.g., washroom, dining area, or therapy) [5]. While activity monitors provide insight into total daily activity [5–10], they do not inform the possible determinants or consequences of this activity. Aerobic capacity is reduced in the early months following stroke [11–13]. Furthermore, poststroke gait is inefficient, and there are increased aerobic demands on those with stroke when walking compared to healthy controls, even when walking at the same speed [14]. Therefore, individuals with stroke are closer to their maximal aerobic threshold when walking than healthy controls. This
Some Switching Invariant Prime Graphs  [PDF]
S. K. Vaidya, U. M. Prajapati
Open Journal of Discrete Mathematics (OJDM) , 2012, DOI: 10.4236/ojdm.2012.21004
Abstract: We investigate prime labeling for some graphs resulted from switching of a vertex. We discuss switching invariance of some prime graphs and prove that the graphs obtained by switching of a vertex in Pn and K1,n admit prime labeling. Moreover we discuss prime labeling for the graph obtained by switching of vertex in wheel Wn.

Open Journal of Discrete Mathematics (OJDM) , 2012, DOI: 10.4236/ojdm.2012.23019
Abstract: We investigate prime labeling for some graphs resulted by identifying any two vertices of some graphs. We also introduce the concept of strongly prime graph and prove that the graphs Cn, Pn, and K1,n are strongly prime graphs. Moreover we prove that Wn is a strongly prime graph for every even integer n ≥ 4.

Open Journal of Discrete Mathematics (OJDM) , 2016, DOI: 10.4236/ojdm.2016.64022
Abstract: A graph \"\" is said to be a product cordial graph if there exists a function\"\" with each edge assign the label \"\", such that the number of vertices with label 0 and the number of vertices with label 1 differ atmost by 1, and the number of edges with label 0 and the number of edges with label 1 differ by atmost 1. We discuss the product cordial labeling of the graphs obtained by duplication of some graph elements of gear graph. Also, we derive some product cordial graphs obtained by vertex switching operation on gear graph.

Abstract:

OBJECTIVE: The primary objective of the S-CORE registry was to assess the safety and efficacy of the Supralimus-Core? sirolimus-eluting stent deployment for the treatment of coronary artery disease and event-free survival of patients treated with this coronary stent. METHODS: S-CORE Registry is an observational, single-arm, non-randomized, post-marketing surveillance multicenter registry in which 562 patients undergoing single or multi-vessel percutaneous coronary intervention were enrolled. The pre-specified primary outcome was the rate of major adverse cardiac events (MACE), defined as the composite of cardiac death, myocardial infarction (MI), target lesion revascularisation (TLR) and target vessel revascularisation (TVR) at 12-month post-procedure. Stent thrombosis (ST) served as the safety endpoint. RESULTS: A total of 640 lesions were treated in 562 enrolled patients (mean age 57.4 ± 10.7 years) with average stent length of 25.0 ± 9.0 mm. Stent delivery was successful in 99% cases. A total of 554 (98.6%) patients have been followed up to 12 months. The incidence of MACE at 30 days and 6 months was 7 (1.2%) and 12 (2.1%) respectively. The composite rate of MACE at a 12-month clinical follow-up was 19 (3.4%), consisting of 12 (2.1%) cardiac deaths, 0 (0%) MI, 6 (1.1%) TLR and 1 (0.2%) TVR. The long-term follow-up of this registry is going on to confirm safety and efficacy profiles. CONCLUSIONS: This multicenter registry demonstrated satisfactory safety and efficacy profiles, as evidenced by low rates of major adverse cardiac events up to 12 months, for the cobalt-chromium biodegradable polymer-based sirolimus-eluting Supralimus-Core? stent in a “real-world” setting.


Efficiency of Urban Bus Companies in India: A Stochastic Frontier Analysis  [PDF]
Sanjay K. Singh
Theoretical Economics Letters (TEL) , 2017, DOI: 10.4236/tel.2017.77130
Abstract: The main aim of this paper is to measure the technical efficiency of publicly owned urban bus companies (UBCs) in India for the period 2000-01 to 2012-13. To examine the efficiency as well as determinants of the same, we estimated a stochastic production frontier based on a translog production function using the maximum likelihood methods. The empirical results reveal that profit and fleet utilization have a significant influence on technical efficiency of UBCs. We find that substantial inefficiencies, averaging between 12 to 41 percent, exist; in general, small and large size UBCs are more efficient than their medium size counterparts. Therefore, there exists no linear relationship between technical efficiency and firm size. We also examined the temporal relationship of the cross-sectional rankings of individual UBCs’ technical efficiency estimates. To address this issue, we calculated Kendall’s index of rank concordance and coefficient of variation of technical efficiency for sample period. It is found that, by and large, there has been stability in ranks across UBCs in regard to their technical efficiency.
