Novel use of wraps for patients with crusted scabies in a resource limited setting
Venue: Dermatologic therapy
Year: 2020

Dear Editor, Crusted scabies is a severe variant of scabies caused by the hyperinfestation with the mite Sarcoptes scabiei var hominis. Conventional therapies for scabies are less successful in treating this condition. Ivermectin in combination with topicals is more effective than topicals alone and is the drug of choice in outbreaks as it allows quick control of lesions and hence decreases spread. Unfortunately, ivermectin is not easily accessible in Sub Saharan Africa and where it is available the cost is exhaustive, precluding public sector patients from benefitting from it. Wet wraps are a well established therapy in atopic eczema and have been successfully adapted for use in psoriasis, pityriasis rubra pilaris, mycosis fungoides, dermatomyositis, urticaria pigmentosa, and erythroderma. The mechanism of actions includes repair of the epidermis, decreased water loss, increase absorption of corticosteroids, and protection from allergens and scratching. To our knowledge wet wraps have not been used in patients with crusted scabies. Seven adult patients who presented consecutively with crusted scabies to our outpatient dermatology clinic over a 1 year period were treated with wet wraps (Table 1) Patients with typical scabies did not receive this regimen. On examination they had hyperkeratotic plaques on the trunk, limbs, hands, and feet with a mean body surface area of 30% involvement (Figures 1 and 2) Fissuring was noted on the hands of four patients. Three patients had concomitant secondary bacterial infection and were treated with flucloxacillin orally prior to wraps. A mixture of 40% salicylic acid 500 g and 100 mL benzyl benzoate was applied to the hands and feet and a mixture of 20% salicylic acid 500 g and 100 mL benzyl benzoate was applied to the trunk and extensors. The lesions were then covered with a double layer of bandages; a moist inner and a dry outer layer  This was repeated for three consecutive days. Benzyl benzoate was then applied for a further 3 days, administered as outpatient therapy. Patients were followed up a week after the initiation of therapy.
Molecular Epidemiology of Clinical Isolates of Imipenem resistant Acinetobacter baumannii from Intensive Care Unit
Year: 2010

To investigate the clonal relationship among the isolates of imipenem resistant Acinetobacter baumannii(IRAB) from intensive care unit and from related environment analyzing with molecular methods and to track the source and spread approach of microbial infections and contamination of IRAB.METHODS Typing the IRAB strains isolated from patients and related environment by genomic DNA using automated DiversiLab (repetitive sequence based polymerase chain reaction,Rep PCR),to identify those strains and test the drug susceptibility by auto microbial analysis system (VITEK 2 Compact).RESULTS Twenty four strains of IRAB isolated from patients and ten strains of A.baumannii (ABA) isolated from environment.The resistant rate of strains of ABA isolated from environment was lower than from clinics(P0.05).Eight of 26 IRAB strains with type A,the major type,were distributed in the second section (5 from patients;1 from environment) and the first section of ICU (3 strains);The second major type was type C which was distributed in the third section (3 from patients;1 from environment).CONCLUSION There is a cross transmission of IRAB between patients and environment in ICU.It is necessary to strengthen the surveillance of ABA,and cut off the spread approach to prevent the outbreak of IRAB.

Endodontic reboot: Adaptive core debridement and disinfective finishing
Year: 2019

Fifty years ago, Dr Herbert B. Schilder introduced two legacy concepts to the science of endodontics: the constricted envelope of motion for instrumentation and the use of hydraulics to enhance the rheology of the obturation material used to seal the root canal space and optimize its gravitometrics. These were radical innovations for their time and despite technological and biological shortcomings of the armamentarium available, these innovations should have been technology iterated and shortcomings in material and manufacturing evolution obviated; however, until recently that has not proved to be the case in toto. In order to truly understand the inherent flaws, the clinician must recognise the totality of what is necessary to engender predictable clinical success in endodontics.
Stimuli Responsive Polymeric Nanosystem for Colon Specific Drug Delivery
Venue: Advanced pharmaceutical bulletin
Year: 2020

An ideal colon specific drug delivery system needs to perform multiple functions like greater bio availability, less toxicity and higher therapeutic efficacy, all of which require high degree of smartness. This article focuses on the overview of the stimuli responsive polymers and various nanodrug delivery systems which have found applications in colon specific delivery of drugs as this system provide a link between therapeutic need and drug delivery. These polymers exhibit a non linear response to a small stimulus leading to a macroscopic alteration in their structure/properties. Stimuli responsive polymers display a significant physio chemical change in response to small changes in their environment (temperature, pH, light etc. Colonic drug delivery has gained increased importance in treating diseases like Crohn's disease, ulcerative colitis, colon cancer etc. The expansion in the development of polymers based system with greater flexibility, versatility and unexplored potential enables new opportunities for them in uplifting bio medicine. Applying the concepts of smartness in the context of clinically relevant therapeutic and diagnostic systems, it can prelude in a new era of 'smart' therapeutics that can improve the health care fields. In particular, due to its high sensitivity to the stimuli, this system has been identified as a sensible platform for releasing drug at suitable site and at appropriate time.
The Crystal Disorder into ZnO with Addition of Bromine and It's Outperform Role in the Photodegradation of Methylene Blue
Venue: Journal of Cluster Science
Year: 2021

In this research work, bromine (Br) is successfully doped into ZnO nanostructures using solvothermal method. The morphology, crystalline features, and composition of Br doped ZnO nanostructures were studied by scanning electron microscopy (SEM) X ray diffraction (XRD) and energy dispersive X ray spectroscopy (EDX) respectively. These newly prepared nanostructured materials were tested as photocatalysts for the photodegradation of methylene blue (MB) in aqueous solution under UV light. The kinetic rate constants were observed in the order (20% Br/ZnO 15% Br/ZnO 10% Br/ZnO 5% Br/ZnO >pristine ZnO) thus they are indicating that the increasing Br dopant level has linear effect on the photodegradation of MB. The photocatalytic degradation efficiency of 60% was achieved for the pristine ZnO during the irradiation of UV light for 5 h, however 20% Br doped ZnO nanostructures has shown enhanced degradation efficiency of 97.63% during the irradiation of UV light for short interval of time of 2.2 h. The 20% Br/ZnO describes the highest rate constant value of (24.13 x 10 3 min 1 for time period of 2.2 h and this values is about 8 and 4 times higher than the pristine ZnO (3.72 x 10 3 min 1 and 5% Br/ZnO (6.13 x 10 3 min 1 respectively. The obtained results of 20% Br doped ZnO sample are superior or equal in performance than the recently reported works. The catalytic mechanism is also proposed and it indicates the role of electrons coming from the bromine ion might act as radical for the degradation of MB. The present approach is simpler, environment friendly, scalable and could be of great consideration for the diverse energy and environment related applications.
Early intensive care unit mobility therapy in the treatment of acute respiratory failure*
Venue: Critical care medicine
Year: 2008

Immobilization and subsequent weakness are consequences of critical illness. Despite the theoretical advantages of physical therapy to address this problem, it has not been shown that physical therapy initiated in the intensive care unit offers benefit. Prospective cohort study in a university medical intensive care unit that assessed whether a mobility protocol increased the proportion of intensive care unit patients receiving physical therapy vs. usual care. Medical intensive care unit patients with acute respiratory failure requiring mechanical ventilation on admission: Protocol, n 165; Usual Care, n 165. An intensive care unit Mobility Team (critical care nurse, nursing assistant, physical therapist) initiated the protocol within 48 hrs of mechanical ventilation. The primary outcome was the proportion of patients receiving physical therapy in patients surviving to hospital discharge. Baseline characteristics were similar between groups. Outcome data are reflective of survivors. More Protocol patients received at least one physical therapy session than did Usual Care (80% vs. 47% p .001) Protocol patients were out of bed earlier (5 vs. 11 days, p .001) had therapy initiated more frequently in the intensive care unit (91% vs. 13% p .001) and had similar low complication rates compared with Usual Care. For Protocol patients, intensive care unit length of stay was 5.5 vs. 6.9 days for Usual Care (p .025) hospital length of stay for Protocol patients was 11.2 vs. 14.5 days for Usual Care (p .006) (intensive care unit/hospital length of stay adjusted for body mass index, Acute Physiology and Chronic Health Evaluation II, vasopressor) There were no untoward events during an intensive care unit Mobility session and no cost difference (survivors nonsurvivors) between the two arms, including Mobility Team costs. A Mobility Team using a mobility protocol initiated earlier physical therapy that was feasible, safe, did not increase costs, and was associated with decreased intensive care unit and hospital length of stay in survivors who received physical therapy during intensive care unit treatment compared with patients who received usual care.
The effects of surface roughness geometry of flow undergoing Poiseuille flow by molecular dynamics simulation
Year: 2014

Numerical simulation of Poiseuille flow of liquid Argon in a rough nano channel using the non equilibrium molecular dynamics simulation is performed. Density and velocity profiles across the channel are investigated in which roughness is implemented only on the lower wall. The Lennard Jones potential is used to model the interactions between all particles. The effects of surface roughness geometry, gap between roughness elements (or roughness periodicity) surface roughness height and surface attraction energy on the behavior of the flow undergoing Poiseuille flow are presented. Results show that surface shape and roughness height have a decisive role on the flow behaviors. In fact, by increasing the roughness ratio (height to base ratio) the slip velocity and the maximum velocity in the channel cross section are reduced, and the density fluctuations near the wall increases. Results also show that the maximum density near the wall for a rough surface is less than a smooth wall. Moreover, the simulation results show that the effect of triangle roughness surface on the flow behavior is more than the cylindrical ones.
Adaptive Event Triggered Control of Nonlinear Systems With Controller and Parameter Estimator Triggering
Venue: IEEE Transactions on Automatic Control
Year: 2020

In this note, the event triggered adaptive control for a class of uncertain nonlinear systems is considered. Unlike the traditional adaptive event triggered control, the controller and parameter estimator are event triggered simultaneously. Asymptotical convergence of stabilization error is guaranteed. To solve this problem, we design a set of event triggering conditions, which is updated for each triggering. At the same time, the input to state stable assumption is not needed. It is shown that the proposed control schemes guarantee that all the closed loop signals are globally bounded and the stabilization error converges to the origin asymptotically. Simulation results illustrate the effectiveness of our scheme.

Year: 2017

Due to the growing demand to improve an environmentally friendly, nonhazardous and cost effective technology as a biocide to control the drug resistant microorganism, thus in the present study; food origin Escherichia coli, Candida zeylanoides and C. krusei were used for the biosynthesis of silver nanoparticles. The biosynthesis of silver nanoparticles was monitored upon the colour change of the reaction mixture by ultraviolet visible spectroscopy. Furthermore, the product was explored by Atomic Force Microscopy; the results revealed the formation of silver nanoparticles in the reaction mixture of the used microorganisms. The biosynthesized silver nanoparticles from E. coli, C. zeylanoides and C. krusei showed a maximum absorption at 423 nm, 415 nm and 426 nm respectively at range between 300 to 800nm wavelength and the size was 64.93 nm, 102.86 nm and 95.37 nm respectively. The biosynthesized silver nanoparticles were tested for their antimicrobial activity against various pathogens Pseudomonas flourescence, Klebsiella pneumonia, E.coli, Candida guilliermondii, and C. albicans; the results showed that the silver nanoparticles that biosynthesized in the current research exhibited an effective antimicrobial activity.

Venue: EKAW
Year: 2020

As a novel contribution to the problem of semantifying biological assays, in this paper, we propose a neural network based approach to automatically semantify, thereby structure, unstructured bioassay text descriptions. Experimental evaluations, to this end, show promise as the neural based semantification significantly outperforms a naive frequency based baseline approach. Specifically, the neural method attains 72% F1 versus 47% F1 from the frequency based method.
Effect of Extra Contribution on Stochastic Optimal Investment Strategies for DC Pension with Stochastic Salary under the Affine Interest Rate Model
Year: 2017

In this paper, optimal investment strategies for defined contribution (DC) Pension, with extra contribution are studied. Our model permits the plan member to make a defined extra contribution, as provided in the Nigerian Pension Reform Act of 2004. The plan member is free to invest in risk free asset, and in two risky assets. A stochastic differential equation of the pension wealth that takes into account certain agreed proportions of the plan member's salary, paid as contribution, and extra contribution towards the pension fund, is presented. The Hamilton Jacobi Bellman (H J B) equation, Legend transformation, and Dual theory are used to obtain the explicit solution of the optimal investment strategies for constant relative risk aversion (CRRA) utility function. We observed that the plan member will increase the proportion of his wealth to be invested in bond and stock and will reduce the proportion to be invested in cash.

Relationships between work home segmentation and psychological detachment from work: the role of communication technology use at home.
Venue: Journal of occupational health psychology
Year: 2011

Employees can have difficulty mentally distancing themselves from work during off job time due to increasing use of communication technologies (e.g. e mail, cell phone, etc. However, psychological detachment from work during nonwork time is important for employee recovery and health. This study examined several antecedents of psychological detachment: work home segmentation preference, perceived segmentation norm, and the use of communication technology at home. Results indicate that segmentation preference and segmentation norm were positively associated with psychological detachment. Further, technology use at home partially mediated these relationships. Findings indicate that segmenting work and nonwork roles can help employees detach and recover from work demands. In addition, findings show that the segmentation norm within a work group is associated with employee experiences outside of work.
Social Ecological Correlates of Regular Leisure Time Physical Activity Practice among Adults
Venue: International journal of environmental research and public health
Year: 2020

This study calculated the exposure response rates of social ecological correlates of practicing regular >150 min/week) leisure time physical activity (PA) in 393,648 adults from the 27 Brazilian state capitals who participated in a national survey between 2006 and 2016. Regular PA encouraging factors were inputted into an exposure response model. Growth rates for the odds ratio and prevalence of regular PA were calculated for each increase of one encouraging factor. Regular PA was reported by 22% of the participants (25% of men and 20% of women) More than 40% of men and 30% of women with higher intra personal encouraging conditions reported practicing regular PA. There was a 3% (ages 18 32 years) to 5% (ages 46 60 years) increase in regular PA practice in men for each increase in an encouraging climate factor (temperature from 21 degC to 31 degC, humidity from 65% to 85% 2430 to 3250 h of sun/year, and from 1560 to 1910 mm of rain/year) Encouraging intra personal factors and favorable climate conditions had larger effects on regular PA practice than the built environment and socio political conditions; the latter two had independent effects, but did not have a cumulative effect on PA.
Deep Diaphragmatic Breathing: A "Portable Intervention" for Stress Reduction among University Students
Year: 2019

Students are at risk for daily stress, often caused by an increasing load of the material to study, limited time and resources necessary to fulfill assignments, personal or family demands, high expectations, pressures, and frustrations. All these factors can create distress, decreased learning abilities, and psychosomatic disorders or diseases. To mitigate such negative biopsychosocial effects of stress, different types of relaxation techniques can be used. Addressing these issues early (e.g. among the 1st and 2nd year university students) seems particularly important, due to possible prevention of the long term adverse health consequences of stress (compared to no intervention) To fulfill this important need, a "portable intervention," such as stress management brief training (SMBT) focused on the reduction of the perceived stress levels among students will be briefly outlined. The SMBT consists of a short review of stress and coping approaches, followed by the instruction of a simple stress management relaxation/technique [e.g. deep diaphragmatic breathing (DDB) Practical considerations regarding the DDB will be highlighted. The feasibility and usefulness of the DDB training for stress management among the 1st and 2nd year university students should encourage implementation of this innovative, safe, inexpensive, and friendly technique.
A Multimodal Anomaly Detector for Robot Assisted Feeding Using an LSTM Based Variational Autoencoder
Venue: IEEE Robotics and Automation Letters
Year: 2018

The detection of anomalous executions is valuable for reducing potential hazards in assistive manipulation. Multimodal sensory signals can be helpful for detecting a wide range of anomalies. However, the fusion of high dimensional and heterogeneous modalities is a challenging problem for model based anomaly detection. We introduce a long short term memory based variational autoencoder (LSTM VAE) that fuses signals and reconstructs their expected distribution by introducing a progress based varying prior. Our LSTM VAE based detector reports an anomaly when a reconstruction based anomaly score is higher than a state based threshold. For evaluations with 1555 robot assisted feeding executions, including 12 representative types of anomalies, our detector had a higher area under the receiver operating characteristic curve of 0.8710 than 5 other baseline detectors from the literature. We also show the variational autoencoding and state based thresholding are effective in detecting anomalies from 17 raw sensory signals without significant feature engineering effort.
Customer Segmentation in Foreign Trade based on Clustering Algorithms Case Study: Trade Promotion Organization of Iran
Year: 2007

The goal of this paper is to segment the countries based on the value of export from Iran during 14 years ending at 2005. To measure the dissimilarity among export baskets of different countries, we define Dissimilarity Export Basket (DEB) function and use this distance function in K means algorithm. The DEB function is defined based on the concepts of the association rules and the value of export group commodities. In this paper, clustering quality function and clusters intraclass inertia are defined to, respectively, calculate the optimum number of clusters and to compare the functionality of DEB versus Euclidean distance. We have also study the effects of importance weight in DEB function to improve clustering quality. Lastly when segmentation is completed, a designated RFM model is used to analyze the relative profitability of each cluster.
