Factors that hinder organ donation: religio-cultural or lack of information and trust

Objectives: This paper examines factors that influence Malaysian persons with a tertiary level of education on their willingness to donate organs. Materials and Methods: A survey was done in the Klang Valley (Kuala Lumpur and its suburbs) at several designated locations. A total of 1420 people were approached, and we focused the sample of 688 respondents with a tertiary level of education. Respondents were given 2 sets of answers: (1) a religio-cultural category and (2) a structural category. They were allowed to choose more than 1 reason. Results: Our findings revealed that only 47.5 percent of respondents declined becoming organ donors. The highest frequency recorded was "I am not convinced that my body part will be used beneficially" (30.1), followed by "I do not have enough access to information" (292), "I want my body to remain intact after death" (16.9), and "It is against my religion" (9.9). Conclusions: Our study revealed that religio-cultural factors are not a prime explanation for the lack of organ donation in the Malaysian case. This study suggests that better procurement methods used by dedicated agencies, as well as better education, could reduce the shortage between organ supply and demand

Development of low frequency high temperature ultrasonic transducers for in-service monitoring of pipework in power plants

In this paper, a low-frequency (20-100 kHz) long-range ultrasonic guided wave transducer for in-service structural health monitoring of high temperature pipework in power plants has been developed. The transducer is designed for continuous operation at a target temperature of 350 °C. This paper describes the methodology followed to develop and test the high temperature transducer. The method includes selection of the suitable piezoelectric material and characterisation of their high temperature properties for the desired thickness-shear mode of vibration to validate its performance at the target temperature. The assembly procedure established for manufacturing transducer is discussed. Ultrasonic performance of the developed transducer was examined and has demonstrated its application for in-service monitoring of pipework operating at the target temperature

Attitudes and beliefs regarding organ donation among South Asian people in the UK

There is an acute shortage of organ donors in the UK, specifically among South Asian communities. This article reports the findings from the largest ever study undertaken among South Asian people in the UK that seeks to explore attitudes and beliefs towards organ donation. This article highlights that seemingly intractable factors, such as religion and culture, are often tied to more complex issues, such as distrust in the medical system and lack of awareness, that contribute to the shortage of organ donors among South Asian communities in the U

Wound contraction effects and antibacterial properties of Tualang honey on full-thickness burn wounds in rats in comparison to hydrofibre

<p>Abstract</p> <p>Background</p> <p>Full-thickness burn wounds require excision and skin grafting. Multiple surgical procedures are inevitable in managing moderate to severe full-thickness burns. Wound bed preparations prior to surgery are necessary in order to prevent wound infection and promote wound healing. Honey can be used to treat burn wounds. However, not all the honey is the same. This study aims to evaluate the wound contraction and antibacterial properties of locally-produced <it>Tualang </it>honey on managing full-thickness burn wounds <it>in vivo</it>.</p> <p>Methods</p> <p>Thirty-six female <it>Sprague Dawley </it>rats were randomly divided into three groups. Under anaesthesia, three full-thickness burn wounds were created on the dorsum of the rats. The full-thickness burn wounds were inoculated with a specific organism (10⁴), namely <it>Pseudomonas aeruginosa </it>(n = 12), <it>Klebsiella pneumoniae </it>(n = 12), or <it>Acinetobacter baumannii </it>(n = 12). The three burn wounds were dressed with <it>Tualang </it>honey, hydrofibre and hydrofibre silver respectively. Swab samples were obtained every 3 days (day 3, 6, 9, 12, 15, 18 and 21) for quantitative and semi-quantitative microbiological analyses. Clinical assessments, including observations concerning the appearance and wound size, were measured at the same time.</p> <p>Results</p> <p>There was a rapid 32.26% reduction in wound size by day 6 (<it>p </it>= 0.008) in the <it>Tualang </it>honey-treated wounds, and 49.27% by day 15 (<it>p </it>= 0.005). The wounds remained smaller by day 18 (<it>p </it>< 0.032). <it>Tualang </it>honey-treated rats demonstrated a reduction in bacterial growth in <it>Pseudomonas aeruginosa </it>inoculated wounds (<it>p </it>= 0.005). However, hydrofibre silver and hydrofibre-treated wounds are superior to honey-treated wounds with <it>Acinetobacter baumannii </it>(<it>p </it>= 0.035). There was no statistical significant of antibacterial property in <it>Klebsiella pneumonia </it>inoculated wounds.</p> <p>Conclusions</p> <p><it>Tualang </it>honey has better results with regards to its control of <it>Pseudomonas aeruginosa </it>and its wound contraction effects on full-thickness burn wound <it>in vivo</it>.</p

Antiproliferative effect of Tualang honey on oral squamous cell carcinoma and osteosarcoma cell lines

<p>Abstract</p> <p>Background</p> <p>The treatment of oral squamous cell carcinomas (OSCC) and human osteosarcoma (HOS) includes surgery and/or radiotherapy which often lead to reduced quality of life. This study was aimed to study the antiproliferative activity of local honey (Tualang) on OSCC and HOS cell lines.</p> <p>Methods</p> <p>Several concentrations of Tualang honey (1% - 20%) were applied on OSCC and HOS cell lines for 3, 6, 12, 24, 48 and 72 hours. Morphological characteristics were observed under light and fluorescent microscope. Cell viability was assessed using MTT assay and the optical density for absorbance values in each experiment was measured at 570 nm by an ELISA reader. Detection of cellular apoptosis was done using the Annexin V-FITC Apoptosis Detection Kit.</p> <p>Results</p> <p>Morphological appearance showed apoptotic cellular changes like becoming rounded, reduction in cell number, blebbed membrane and apoptotic nuclear changes like nuclear shrinkage, chromatin condensation and fragmented nucleus on OSCC and HOS cell lines. Cell viability assay showed a time and dose-dependent inhibitory effect of honey on both cell lines. The 50% inhibitory concentration (IC_<b>50</b>) for OSCC and HOS cell lines was found to be 4% and 3.5% respectively. The maximum inhibition of cell growth of ≥80% was obtained at 15% for both cell lines. Early apoptosis was evident by flow cytometry where percentage of early apoptotic cells increased in dose and time dependent manner.</p> <p>Conclusion</p> <p>Tualang honey showed antiproliferative effect on OSCC and HOS cell lines by inducing early apoptosis.</p
