Published: August 2012

A prospective randomized cohort study was done in 100 patients and the study population consisted 50 patients with unheralded acute myocardial infarction and 50 with uncomplicated stable angina pectoris. The main objectives of the study were to compare the angiographic severity between the two clinical subsets of IHD. The study observed that regarding number of vessels diseased , the AMI group had 1.52±0.68 compared with 2.37±0.85 vessels for the angina group reflecting significantly higher diseased vessel in latter group (P<0.001). In comparison with unheralded AMI, the stable angina group had greater number of stenoses(4.16±1.9 vs 2.14±1.5, P<0.001) and also greater number of occlusions(0.80±0.65 vs 0.44±0.31, P<0.001 ). Thus from the above data it is clear that single vessel disease is more frequent in AMI group and double- and tripple vessel diseases are more prevalent in angina group and fewer stenoses and discrete type of lesions in the former and more number of diseased vessels, more stenoses, and diffuse type of lesions in the latter.

To correlate magnitude and distribution of coronary Artery Disease (CAD) with ischaemic limb changes in patients with Peripheral Arterial Disease (PAD) of lower limbs.Most common cause of PAD is atherosclerosis. Atherosclerosis is a generalized disease and often atherosclerotic CAD is associated with PAD. Because of ischaemic limb changes in patient with PAD they do not always experience angina even after having CAD. This prospective observational study was conducted in National Institute of cardiovascular Diseases (NICVD) Dhaka, Bangladesh during July 2004 to June 2005. Total 58 patients with PAD were included in the study. Patients were classified as group I having normal coronary artery, group-II insignificant CAD (L M <50% stenosis, others <70% stenosis) and group-III significant CAD (LMe 50% stenosis, others e 70%, stenosis). Ischaemic limb changes was significantly higher in patients with CAD compare to non-coronary artery disease (P = 0.047).This study suggests that ischaemic limb changes had significant relation with the presence of CAD.

Published: August 2012

Dyslipidemia is highly prevalent in the urban and rural areas of Bangladesh but information in the suburban, is limited. The objective of this study was to determine the prevalence of dyslipidemia in sample population who live in the sub-urban area of Bangladesh. Random sampling of the volunteers aged > or = 18 years in Bhaluka upozilla of Mymensingh district was done. After 12-hour fasting, the blood sampling was drawn for the analysis of fasting glucose, total cholesterol, triglycerides, high-density lipoprotein (HDL) cholesterol and low-density lipoprotein (LDL) cholesterol. In the present study, we have shown that there is increasing trend of dyslipidemia even in the sub-urban community. Women had significantly higher body mass index, serum cholesterol and LDL cholesterol levels than men after 40 years of age. Of the study population 16.9% had high TC (e240 m/dl), and 8.8% had low HDL-C (d40 mg/dl). The population with high (e160 mg/dl) LDL-C was 15.7%. In addition, 17.8% had high TG (e200 mg/dl) and 2.0% had very high TG (e350 mg/dl). Our findings also suggest a protective role of ordinary Bangladeshi diet such as fish cooked in mustard oil on dyslipidemia. Individually, both fish and the mustard oil are rich in unsaturated fatty acids, and biologically, their beneficial effects are related not only to reduction of blood pressure, but also to lowering of lipids and to their antithrombotic effects. In conclusion, prevalence of dyslipidemia was very high in Bangladeshi sub-urban region. Useful role of fish cooked in mustard oil, as a protective factor needs to be probed further in future longitudinal studies. The observed prevalence of dyslipidemia in this study suggests the need for a comprehensive national policy to control dyslipidemia in Bangladesh. Further surveillance in this population is essential in verifying the impact of dyslipidemia as a risk of cardiovascular disease in Bangladeshi people.

Combining Thyroidectomy with Cardiac Surgery: Implications for the Endocrine Surgeon
Authors: Daniel Sudin Varghese , Lansdown Mark Reginald 
Published: August 2012

ABSTRACT
The management of incidentally detected retrosternal goiter in patients with cardiac disease awaiting open heart surgery is controversial. Here, we present the case of a 79-year-old man; who had coronary artery bypass grafting, aortic valve replacement and thyroidectomy for retrosternal goiter under a single anesthetic. A literature search was conducted to study patient demographics, thyroid symptomatology, pathology, complications and the risks and benefits of the combined procedures. Literature search revealed only a few similar cases of a combined surgical approach and these are from the perspective of the cardiac surgeon. The study is presented to highlight the implications of such combined procedures for the endocrine surgeon.
A medline search was conducted for combined procedures on heart and thyroid. Five case reports and two reviews, including one case of off-pump coronary artery bypass grafting (CABG) was obtained. The mean age of the patients was 69 years (range, 55-79). Retrosternal goiter was the commonest indication (67%), half of them presenting with tracheal compression. Thyrotoxicosis was observed in 22%. Beinign multinodular goiter was the commonest pathology (89%). There was one case of Grave's disease. There were no reported malignancies. There were no reported complications from the endocrine surgery.
The various cardiac procedures in the combined operations were coronary artery bypass grafting, aortic valve replacement, mitral valve replacement, a combination of these and a case of closure of atrial septal defect.
The review has looked into the anatomical and physiological implications of combined operations, operative risks and has upheld the safety of such combined procedures.

ABSTRACT
Thyroid disease in Uganda continues to be endemic, despite national salt iodinization. This study describes the local characteristics of thyroid disease and identifies potential barriers to surgical access. A prospective database was established for all patients with suspected thyroid disease who presented to the Endocrine Surgery Clinic at Mulago National Referral Hospital in Kampala, Uganda in 2008. A cross-sectional study collected and analyzed for presentation, diagnostics and the surgical plan. A total of 89 patients were included, with an average age of 40 years, and 88% were women. The most common presentation was compressive symptoms (39%, n = 35), signs and symptoms of hyperthyroidism (30%, n = 27) and cosmetic concerns (16%, n = 14). Ultrasound, which is subsidized by the hospital, was performed in 85% of patients (n = 76). Thyroid function tests (TFTs), which are less subsidized, were done in 67% (n = 60). Of these, 27% (n = 16) were hyperthyroid and 7% (n = 4) were hypothyroid. Fine needle aspiration was done in 30% (n = 27) and were suspicious for malignancy in 27% of patients (n = 7). The most common diagnosis was multinodular goiter (n = 55) and tracheal compression or deviation and/or retrosternal extension was seen on imaging in 22 of 75 patients (29%). Thyroid disease in Uganda is more advanced, involves a different population than in Western countries and includes high rates of symptomatic multinodular goiter and cancer. Resource constraints limit the care of these clinically challenging conditions. Further evaluation of these potential barriers to surgical care needs to be conducted.

Published: August 2012

ABSTRACT
Quadruple primary malignancies occur with an incidence of less than 0.1%. Only less than hundred cases have been published until today. The number of multiple malignancies reported is gradually increasing. Here, we present a female patient with a multiple sclerosis and quadruple cancers from different embryological origin. The patient had medullary thyroid carcinoma (stage III-T3, N1a, M0) and multicentric micropapillary carcinomas, two melanomatous lesions, 1.24 and 0.85 mm thick (Clark II, Breslow II) and breast cancer (T1a, N0, M0). There were no signs of disease recurrence during the 5 years including the exam performed last month. Further genomic studies and closer clinical attention are needed to clarify the relation between secondary malignancies, applied treatments and endogenous and exogenous carcinogens in the process of carcinogenesis in quadruple malignancies.

A Novel Approach of Videothoracoscopic Surgery for Posterior Mediastinal Goiter
Authors: PRK Bhargav , Amar V , Uday SK 
Published: August 2012

ABSTRACT
Intrathoracic extension of large goiters occasionally requires thoracic approaches, such as sternotomy, anterior or posterolateral thoracotomy. Videothoracoscopic technique is a minimally invasive approach, but usually done under single lung ventilation with double lumen endotracheal tube anesthesia. But, this newer technique of thoracoscopic dissection and delivery of posterior mediastinal goiter with partial lung collapse minimizes the postoperative morbidity and pulmonary complications.

Structure–Property Relations in All‐Organic Dye‐Sensitized Solar Cells
Authors: Jiao Yang , Zhang Fan , Grätzel Michael , Meng Sheng 
Published: August 2012

AbstractA structure–property relationship in all‐organic dye solar cells is revealed by first‐principles molecular dynamics and real‐time time‐dependent density functional theory simulations, accompanied with experimental confirmation. An important structural feature at the interface, Ti–N anchoring, for a broad group of all‐organic dyes on TiO2 is inferred from energetics, vibrational recognition, and electronic data. This fact is contrary to the usual assumption; however, it optimizes electronic level alignment and photoelectron injection dynamics, greatly contributing to the observed efficiency improvement in all‐organic cyanoacrylate dye sensitized solar cells.
Hedonic Analysis of Price Expectations of Goat Producers in Afghanistan: Implications for Production and Marketing Decisions
Authors: Srinivas Tavva , Aw‐Hassan Aden , Rischkowsky Barbara , Tibbo Markos , Rizvi Javed , Naseri Abdul Halim 
Published: August 2012

ABSTRACTThe authors describe the goat markets in Afghanistan by analyzing goat producers’ price expectations and by identifying the factors that determine these price expectations. Data on expected prices for goats transacted were collected from 280 goat producers from Baghlan and Nangarhar provinces, along with information on factors anticipated to influence the price expectation from May 2008 to April 2009. A price expectation model was built and analyzed using a general linear model.Results indicated that goat producers adjusted expected prices for marketing day (Saturday and Thursday), location of sales (district and provincial markets), live weight, and goat producers’ market network. However, goat producers did not expect a premium for goat attributes like breed and age. The implications of the study are that goat producers can expect more when they plan their goat sales based on live weight, market day, marketing place and sex of goat.

Advanced imaging to extend the therapeutic time window of acute ischemic stroke
Authors: Fisher Marc , Albers Gregory W. 
Published: August 2012

AbstractReperfusion therapy for acute stroke has evolved from the initial use of intravenous tissue plasminogen activator (tPA) within 3 hours of symptom onset to more recent guideline‐recommended use up to 4.5 hours. In addition, endovascular therapy is increasingly utilized for stroke treatment and is typically initiated up to 8 hours after onset. Recent studies demonstrate that imaging of the ischemic penumbra with diffusion/perfusion magnetic resonance imaging (MRI) can identify subgroups of patients who are likely to improve following successful reperfusion (Target Mismatch profile) and others who are at increased risk for hemorrhage and poor clinical outcomes (Malignant profile). New data indicate that stent retriever devices provide better recanalization efficacy and clinical outcomes than the previously available mechanical thrombectomy devices. Going forward, we believe that the use of penumbral imaging with validated MRI techniques, as well as the currently less well‐validated computed tomography (CT) perfusion approach, will maximize benefit and reduce the risk of adverse events and poor outcomes when used both early after stroke onset and at later time points. New trials that feature diffusion/perfusion MRI or CT perfusion‐based patient selection for treatment with intravenous tPA and or endovascular therapies versus nonreperfused control groups are planned or in progress. We predict that these trials will confirm the hypothesis that penumbral imaging can enhance patient selection and extend the therapeutic time window for acute ischemic stroke. ANN NEUROL 2013.

Poly(vinyl alcohol)/quaternized lignin composite absorbent: Synthesis, characterization and application for nitrate adsorption
Authors: Li Ying , Lin Xiaoyan , Zhuo Xiurong , Luo Xuegang 
Published: August 2012

AbstractA new poly(vinyl alcohol) (PVA)/quaternized lignin composite absorbent (PVA/QL) was synthesized from modified lignin and PVA, crosslinked by glutaraldehyde. As‐prepared absorbent was characterized by IR, DSC, SEM BET, and DMA. Effects of shaking time, absorbent dose, initial pH, and temperature on NO3− removal from aqueous solution by the absorbent were comprehensively investigated. The results show that the PVA/QL absorbent comprises quaternary ammonium groups in the form of ether bond. The composite absorbent exhibits remarkable network structure with large numbers of connected holes. The mechanical strength of the absorbent is enhanced by combining of PVA with modified lignin and crosslinkage of glutaraldehyde. The effect of pH on adsorption of NO3− is apparent and appropriate pH is 2.0. The adsorption process is endothermic, and determined to be consistent with the Langmuir isotherm. Furthermore, it is found that the quaternary ammonium structure and network structure in the surface of PVA/QL are the key factors to remove nitrate. © 2012 Wiley Periodicals, Inc. J. Appl. Polym.

AbstractAn aryl phosphinate dianhydride 1,4‐bis(phthalic anhydride‐4‐carbonyl)‐2‐(6‐oxido‐6H‐dibenz[c,e][1,2]‐oxaphosphorin‐6‐yl)‐phenylene ester (BPAODOPE) was synthesized and its structure was identified by FTIR and 1H‐NMR. BPAODOPE was used as hardener and flame retardant for preparing halogen‐free flame‐retarded epoxy resins when coupled with another curing agent. Thermal stability, morphologies of char layer, flame resistance and mechanical properties of flame‐retarded epoxy resins were investigated by thermogravimetric analysis, SEM, limiting oxygen index (LOI), UL‐94 test, tensile, and charpy impact test. The results showed that the novel BPAODOPE had a better flame resistance, the flame resistance and char yield of flame‐retarded epoxy resins increased with an increase of phosphorus content, tensile strength and impact strength of samples gradually decreased with the addition of BPAODOPE. The flame‐retarded sample with phosphorus contents of 1.75% showed best combination properties, LOI value was 29.3, and the vertical burning test reached UL‐94 V‐0 level, tensile strength and impact strength were 30.78 MPa and 3.53 kJ/m2, respectively. © 2012 Wiley Periodicals, Inc.

Utilization of cellulosic wastes in textile and garment industries. I. Synthesis and grafting characterization of carboxymethyl cellulose from knitted rag
Authors: Fakrul Alam A. B. M. , Mondal Md. Ibrahim H. 
Published: August 2012

AbstractCarboxymethyl cellulose (CMC) was synthesized from knitted rags, a cellulosic wastes of textile and garment industries, in aqueous ethanolic sodium hydroxide and subsequently mono‐chloroacetic acid reaction medium. A low substituted to high substituted products was obtained from single step up to seven steps carboxymethylation of cellulose. In this way, it was possible to produce low cost and different grades or substituted carboxymethylation derivatives of cellulose. Solubility, degree of substitution (DS), CMC content, and molecular weight of CMC were increased gradually with the increase of the number of reaction steps, although fourth step attained optimal. The DS of CMC from one to seven reaction steps was 0.91–2.84, respectively. Similarly, CMC content and molecular weight of CMC were 72.60%–85.00% and 153,886–252,231, respectively. Grafting of CMC film with methyl methacrylate (MMA) improved strength properties, but it decreased moisture content due to the incorporation of hydrophobic MMA monomer. The prepared CMC, when applied as sizing agent to cotton fabric, was deposited on the fabric surface through bond formation making it smooth without any crack or rupture. © 2012 Wiley Periodicals, Inc.

Published: August 2012

AbstractOxidized carboxymethyl cellulose (OCMC) was prepared by an oxidation reaction of carboxymethyl cellulose in the presence of sodium periodate. In situ crosslinked hydrogels were obtained through the crosslinking reaction between the active aldehyde of OCMC and the amino groups of the carboxymethyl chitosan (CMCS). The structure of the hydrogels was characterized by FTIR and scanning electron microscopy. Gelation time test showed that the hydrogel had the shortest gelation time of 24 s. The equilibrium fluid content, which represented the swelling degree, was evaluated and we found that the pH increased from 3.0 to 9.0, the equilibrium fluid content increased, and the highest equilibrium fluid content reached 312.83% as pH = 9.0. The wound healing efficacy of the hydrogel was evaluated in experimental deep second degree burns using a rat model. Results indicated that the wound covered with hydrogel was completely filled with new epithelium within 2 weeks, without any significant adverse reactions. The in situ crosslinked hydrogel fulfilled many critical elements in a wound dressing material. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
