MIOCARDIAL VIABILITY ASSESSMENT IN CARDIAC SURGERY : CLINICAL PRACTICE AND PROGNOSTIC VALUE

About 6 million new cases of coronary heart disease (CHD) are registered in the world with more than 1.3 mln of them in Europe. The development of chronic ischemic heart disease (CHD) is the most important factor contributing to the increased prevalence of heart failure. Heart failure (HF) associated with the CHD is one of the main causes of mortality and morbidity. The long term prognosis of patients with HF is poor and this is despite the modern pharmacotherapy and device-based therapy (Hobbs et al., 2002). Surgical revascularization is an alternative approach in patients with chronic CHD and HF. However, high surgical risk, especially in patients with severe LVH or very low LVEF, and poor clinical outcomes with lack or minimal improvement in LV function after revascularization prevent the more active and extensive use of surgical revascularization methods in this group of patients. However, the high surgical risk in patients with severe LV dysfunction (LVD) or with very low LV EF as well as poor clinical results with absence or insignificant improvement in LV function following revascularization prevent more active and wider use of surgical revascularization in these groups of
CHOP is the standard regimen in patients > or = 70 years of age with intermediate-grade and high-grade non-Hodgkin's lymphoma: results of a randomized study of the European Organization for Research and Treatment of Cancer Lymphoma Cooperative Study Group.

PURPOSE We report the results of a randomized study of the European Organization for Research and Treatment of Cancer (EORTC) Lymphoma Group, which compared a chemotherapy regimen specifically devised for elderly patients, ie, etoposide, mitoxantrone, and prednimustine (VMP), versus the standard regimen of cyclophosphamide, doxorobucin, vincristine, and prednisone (CHOP) in patients older than 70 years of age with intermediate- and high-grade non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS Patients older than 70 years of age with stage II, III, or IV intermediate- and high-grade NHL, with an Eastern Cooperative Oncology Group (ECOG) performance status less than 4 and acceptable cardiac, renal, and liver function were randomized to receive six courses of VMP or six courses of CHOP. Between February 1989 and June 1994, 130 patients aged 70 to 93 years (median, 75) were enrolled and 120 were assessable for response, 60 patients in each arm. RESULTS Overall objective response rates were 50% and 77% in VMP- and CHOP-treated patients, respectively (P = .01), while complete response (CR) rates were borderline significant (27% v 45%; P = .06). At 2 years, the progression-free survival (PFS) rate was 25% with VMP versus 55% with CHOP (P = .002) and the overall survival (OS) rate was 30% with VMP versus 65% with CHOP (P = .004). Statistically significant more alopecia and neurologic and gastrointestinal toxicities were reported with CHOP. CONCLUSION CHOP is the standard regimen for patients > or = 70 years of age with stage II to IV intermediate- and high-grade NHL.
Antioxidant , Ferric Iron Chelation and Antimicrobial Activities of Extracts of Pseudocydonia sinensis ( Chinese Quince ) Fruit

There are accumulated lines of evidence on the importance of plants as natural sources of medicinal agents since most synthetic antioxidants and antibiotics have been implicated in cytotoxicity and microbial resistance. However, biological activities of phytochemicals are partly dependent on extraction solvents. In this study, the antioxidant, ferric ion chelation and antimicrobial activities of the fruit extracts of Pseudocydonia sinensis (Chinese quince) were examined. The methanol, aqueous and ethanol extract recorded highest antioxidant, ferric ion chelation and antimicrobial activities, respectively. The ethanol and methanol extracts showed significant antimicrobial activities against all microbes employed in this study. The fruit extract may therefore be a promising source of antioxidant and antimicrobial agents of natural origin.
Virtual Clusters for Dynamic Network Service Chaining

Network service chaining is a service deployment concept that enables network operators to configure network services dynamically in software without making any changes to the hardware. With software defined networking and network function virtualization, network service chaining is gaining a serious attention in the research community. However, its concept is still vague and advantages are yet not clear. Therefore, in this paper, we discussed an architecture for the orchestration of multiple service chains on the underlying infrastructure and explain the workflow of a service chain. With this architecture, applications can create and manage their service chains independently.
Mechanism of Antimicrobial Resistance in Bacterial Biofilms

Biofilm is defined as a community in which microorganisms adhere to a living or inanimate surface, embedded in a gelatinous layer in a self-produced matrix of extrapolymeric substances, adhered to each other, to a solid surface or to an interface. In food industry, biofilm formation is undesirable as they cause food spoilage, damages in food processing equipment and diseases due to pathogenic contamination. Biofilms are more resistant to antimicrobial agents than planktonic cells. There are various possible mechanisms responsible for antimicrobial resistance of the bacteria in biofilms. The main factors that affect resistance mechanism in biofilms are characterized as exopolysaccharide matrix, enzymes, heterogeneity, cellular persistence, metabolic activity, genetic adaptation, quorum sensing, stress responses, outer membrane structure and efflux pumps. A whole understanding of resistance mechanisms can provide benefits to prevent and control biofilm formation. As a result, researchers should initially focus on the mechanisms of resistance for effective biofilm control and then protective measures must be taken. In the present review, the resistance mechanisms of bacterial biofilms in food industry against antimicrobial agents are focused.
The Cost and Quantity of Carbon Sequestration by Extending the Forest Rotation

Increasing forest management and extending the timber rotation age beyond the economically optimal age have been proposed as options for increasing carbon sequestration. In this paper we examine the potential costs and quantity of sequestered carbon from such activities for forests in the southern and western regions of the U.S. A model of optimal rotations when carbon is a valued asset is presented to show how optimal rotations will adjust when carbon is priced. Data on a range of softwood forest types and site classes in 12 southern and western states that dominate softwood timber production in the U.S. are then used to examine the costs of extending rotations. The results indicate that carbon sequestration is relatively expensive from extending rotations. In these 12 states, about 4.1 million t C could be sequestered for less than $25 per t C (1 t C = 1000 Kg Carbon), although for high carbon prices of $200 per t C. , up to 57 million t C could be sequestered. Timber prices are found to have important influences on the marginal costs of carbon sequestration, with site quality being of secondary importance. The results also show the carbon prices that would be necessary to set-aside timberland. Very little land would likely be set aside at $50 per ton C, however, at $200 per t C, the results indicate that nearly 1 million hectares of land could be set-aside in the U.S., with 83% of this land occurring in the Western U.S.
Potential of coconut milk and mung bean extract combination as foam stabilizer in non-dairy ice cream

Non-dairy ice cream is one of many food products that are currently developed especially for vegetarians. The use of coconut milk in the manufacture of non-dairy ice cream made from extracts of mung bean (Vigna radiata) is expected to increase foam stabilization of ice cream mixture. Coconut milk can serve as fat and protein sources that are needed in the formation of emulsion and stabilization of the foam system that will determine the characteristic of non-dairy ice cream. The aims of this research was to study the potential of a combination of coconut milk and mung bean extract as a foam stabilizer on a non-dairy ice cream mixture. A single factor randomized block design was used and the ratios of mung bean extract : coconut milk (w/w) consisted of four levels, namely P1, P2, P3 and P4, respectively for 90 : 10, 85 : 15, 80 : 20 and 75 : 25. The experiments were carried out with three replications. The viscosity of the mixture was affected by the mixture components such as starch and albumin that are capable of trapping water in gel formation during heating process. Globulin and albumin enveloped the air bubbles and stabilized the emulsion by increasing the foam stability. Combination of mung bean extract and coconut milk in the ratio of 85 : 15 gave the maximum effect on foam stability. This is related to the proportion of the total solids and viscosity that were relatively high compared to the other combinations.
STRUCTURAL AND MECHANICAL PROPERTIES OF AMORPHOUS SILICON : AB-INITIO AND CLASSICAL MOLECULAR DYNAMICS STUDY

Understanding the surface properties of amorphous silicon (a-Si) is extremely important for effective application of a-Si in its wide usage as a thin film material. Several theoretical works using ab-initio molecular dynamics schemes have been performed to investigate this subject. However, due to the limited time scale accessible to the ab-initio scheme, the resulting a-Si structure has not been subject to sufficient relaxation. One possible way to resolve this time scale problem is to employ classical molecular dynamics (CMD), because this method can handle the large time scale required to relax the amorphous structure. In this study, a combined method of a CMD calculation with the Tersoff empirical potential and an ab-initio calculation based on density functional theory has been performed. The main role of the CMD method is to sufficiently relax the amorphous structure. Subsequently, the results of the CMD calculations are used as starting points for ab-initio calculations. As a result, this combination method can provide quantitative evaluation of the surface energy and surface stress of well-relaxed amorphous silicon in addition to its structure. Using this combination method, a surface energy of 1.05±0.14 J/m and a surface stress of 1.5±1.2 N/m were obtained. This calculation also led to a new discovery of the microscopic characteristic of a-Si surface, which was not revealed through the use of an empirical potential. It was shown that there are two types of threefold coordinated atoms at the surface region; one with p-like bonding and the other with sp-like bonding. In addition, the investigation indicated that the microstructures of these defects were different from those of a threefold coordinated atom observed in the bulk structure.
Sample Boxes for Retail Products : Bundling Experience Goods to Leverage Consumer Uncertainty Motivation

Motivation: Buyers often have uncertain a priori product valuations for firms’ offerings. In order to resolve this uncertainty and discover their preferred products, consumers may need to ultimately try multiple product variations, via sequential trials. A trending alternative technique for facilitating consumers’ discovery of product valuations is for firms to offer sample boxes. A typical sample box includes a set of product varieties within a specific product category. Sample boxes are prevalent in both online and brick-and-mortar businesses. A prominent example in the online setting is Amazon, which has recently been offering sample boxes in such product categories as coffee, hair and skin care, sports nutrition, men’s grooming, and pet treats. Similarly, big-box retailers such as Target and Walmart offer sample boxes in multiple product categories including fragrances, cosmetics, and skin care products. Offering sample boxes is also a common practice that has been adopted by smaller businesses; online examples include Verdant Tea’s loose tea, Bubble Bandit’s dishwasher detergent, and Master of Malt’s whiskey sample boxes. The sample box concept may apply in different contexts under different names. For example, in a service context, wine and beer sampler “flights” may facilitate consumers’ discovery of their preferences through bundling multiple product varieties.
CAUSES OF FAILURE AMONG BUMIPUTRA CONTRACTORS

Malaysian government has introduced several policies in helping the indigenous people known as Bumiputra. Amongst the actions is by awarding certain government contracts to bumiputra contractors only. Unfortunately, many of the contractors are not able to survive in this contractural business due to many factors that has commonly been highlighted in local newspaper. Thus, this paper presents a preliminary investigation on bumiputra’s contractors failure factors in southern parts of Malaysia peninsular. At the initial stage of this study, an interviewed was carried with the Secretary of Malaysian Malay Contractors Association in Johor on the issues faced by Bumiputra contractors. He pointed 10 issues that usually engulfed Bumiputra contractors during handling the awarded projects. Then, a survey was carried with 15 selected bumiputra contractors who are well experienced in handling construction projects to gauge their views on the relevancy of 19 identified factors which are clustered into 6 groups. The collected data was analyzed by using mean score to rank these factors according its degree of relevancy to bumiputra contractors issues. This study found 5 most relevant factors that are two factors from financial group, two factors from risk group and one factors from other resources. These factors are F2insufficient cash flow/capital to carry out a construction project, F3-difficulty in securing bank loan due to inability to get guarantor/collateral fixed, R1-unable to anticipate the difficulty of getting material and worker, R3-unable to anticipate risks from material price escalation and OR2-lack of construction skilled workers (foreman, carpenters, bricklayer, etc). These findings are very helpful for the Bumiputra contractors in preparing an effective construction project management strategy for their future project.
Preparation of nano bioactive glass and investigation of its properties in different volume of solution

Nano Bioactive glass material of the type CaO–P2O5–SiO2 was obtained by the sol-gel processing method at considerably lower temperatures than required for conventional melting methods. As a new modification, volume of solution was changed in order to investigate its effects on the properties of bioglass samples. The obtained material was characterized by X-ray powder diffraction (XRD), surface electron microscopy (SEM) and Transmission electron microscopy (TEM) to evaluate the properties of the sol-gel derived bioactive powders. More homogeneous nano bioactive glass with almost 20 nm particles was obtained by higher volume of solution.
Endoscopic pyloroplasty for severe gastric outlet obstruction due to alkali ingestion in a child

A common belief is that alkali ingestion causes severe esophageal damage and limited gastric injury due to the buffering action of acid. Gastric injury has been observed in patients who ingested alkali. Gastric outlet obstruction (GOO) secondary to caustic ingestion occurs due to fibrosis after resolution of the acute injury and inflammation, most commonly 6 to 12 weeks after initial ingestion. The traditional treatment for GOO related to ingestion of corrosive agents is surgery. Experience with endoscopic balloon dilation of corrosive-induced GOO is limited in children. This is the first report of endoscopic pyloroplasty in a child with GOO due to caustic alkalis ingestion that was treated with balloon dilation (using TTS balloon ranging from 6-15 mm) in Iran. Four dilation sessions were required for symptomatic relief of dysphagia. After one year of follow up, weight gain was normal.
Analysis of Framelets for the Microcalci fi cation

Mammography is used commonly to detect the cancer in breast at the early stage. The early stage of breast cancer detection helps in avoiding the removal of breast in women and even the death caused due to breast cancer. There are many computer aided softwares that are designed to detect breast cancer but still only biopsy method is effective in predicting the exact scenario. This biopsy technique is a painful one. To avoid this, a novel classification approach for classifying microcalcification clusters based on framelet transform is proposed. The real -time mammography images were collected from Sri Ramachandra Medical Centre, Chennai, India in order to evaluate the performance of the proposed system. The GLCM features (contrast, energy and homogeneity) are extracted from the framelet decomposed mammograms with different resolution levels and support vector machine classifier is used to classify the unknown mammograms into normal or abnormal initially and then further classifies it as benign or malignant if detected as abnormal. The result shows that framelet transform-based classification provides considerable classification accuracy.
Evaluation of User Experience of New Defense Medical Information System

Objectives This study aimed to investigate the user experience (UX) of the New Defense Medical Information System (N-DEMIS), which was introduced in 2012 as part of an effort to improve the old system of armed forces hospitals and ultimately bring their standards up to those of civilian hospitals. Methods In this study, the dependent variable was the UX of N-DEMIS and was composed of usability, affect, and user value. The questionnaire comprised 41 questions: nine on general characteristics, 20 on usability, four on affect, and eight on user value. The data collection period was from April 15 to April 30, 2018. Overall, 85 responses were received; of these, three insincere responses were excluded, and the remaining 82 responses were used in the analysis. Results The overall value of Cronbach's alpha was 0.917, indicating an overall high-reliability. There was a significant difference between user value and usability, but there was no significant differences between the other pairs. We observed a significant effect on UX for length of time working in an armed forces hospital and employment type. Conclusions The results of our survey showed an even distribution of scores across the three elements of UX, showing that no particular aspect of N-DEMIS is superior to the others in terms of user satisfaction. However, the overall UX score of around 60% indicates the need for future improvements. Rather than focusing improvements on a specific area, improvements should be spread across usability, affect, and user value.
Behind Traditional Semi-quantitative Scores of Myocardial Perfusion Imaging: An Eye on Niche Parameters

The evaluation of stress-induced myocardial perfusion defects by non-invasive myocardial perfusion imaging (MPI) modalities has a leading role in the identification of coronary artery disease, and has excellent diagnostic and prognostic value. Non-invasive MPI can be performed using conventional and novel gamma cameras or by PET/CT. New software has allowed novel parameters that may have a role in the identification of early marks of cardiac impairment to be evaluated. We aim to give an overview of niche parameters obtainable by single photon emission CT (SPECT) and PET/CT MPI that may help practitioners to detect initial signs of cardiac damage and identify new therapy targets. In particular, we summarise the role of left ventricular geometry indices for remodelling, phase analysis parameters to evaluate mechanical dyssynchrony, the concept of relative flow reserve in the evaluation of flow-limiting epicardial stenosis, vascular age and epicardial adipose tissue as early markers of atherosclerotic burden, and emerging parameters for the evaluation of myocardial innervation, such as the total defect score.
Complex regional pain syndrome: diagnosis and treatment at the very onset as the key to success? A case report with implications for first contact doctors

The case report describes a 67-year-old man who suffered from a minor left ankle injury. Physical examination on day 12 revealed swelling of the foot, erythema on its dorsal surface as well as elevated temperature, hyperesthesia, hyperalgesia and allodynia of that area. The treatment included local application of dexamethasone and oral administration of meloxicam. Within a week the symptoms disappeared and one-year follow-up did not show their recurrence. The presented symptoms allowed diagnosis of the earliest stage of complex regional pain syndrome (CRPS), which may be a disabling and difficult to treat adverse event. This report suggests that immediately introduced simple anti-inflammatory therapy may bring a quick and permanent recovery. Hence, first contact physicians should advise the patient to report such symptoms as burning pain of the injured area lasting for a few days and, if CRPS suspicion is justified by the results of physical examination, they should apply an anti-inflammatory treatment immediately.
Determination of antibodies in everyday rheumatological practice

Antibody determination is routinely used in everyday rheumatological practice. Its result repeatedly determines the diagnosis or exclusion of a particular disease. Antibodies are immunoglobulins, i.e. some of the most important proteins in the immune system, and have specific properties that we should know. In addition, there are a number of factors that can affect their concentration, including drugs commonly used in the treatment of rheumatic diseases. There are definite indications, when the total concentrations of individual classes of immunoglobulins should be initially determined and it should be evaluated whether the patient produces them at all or their production is impaired. In some cases, we should evaluate the levels of specific antibodies along with the total protein concentration and the γ-globulin fraction, in which the antibodies are contained. The article presents information on the most common mistakes made when performing these tests.
