Non-alcoholic fatty liver disease (NAFLD) is a series of liver disorder caused by deposition of fat without involving alcohol. This chronic liver disease has become a major concern globally due to its high mortality and morbidity rate. This situation leads to the quest of finding natural remedy to overcome this condition. Ficus deltoidea or commonly known as mistletoe fig or Mas Cotek, is a plant that is very well known especially in Malaysia for its blood glucose lowering effect. However, the potential value of F. deltoidea has not been fully evaluated, and no studies have been published on the effects …


Surface Modification Of Biomaterials To Reduce Polyethylene Wear In Metal-Polymer Contact / Tan Mean Yee, Tan Mean Yee Sep 2020

Surface Modification Of Biomaterials To Reduce Polyethylene Wear In Metal-Polymer Contact / Tan Mean Yee, Tan Mean Yee

Student Works (2020-2029)

This research focus on studying different surface modification (Texturing and DLC coating) on the metal part of TKR (Total knee replacement) in improving UHMWPE (Ultra-high molecular weight polyethylene) wear. TKR was widely being used to relieve knee pain due to osteoarthritis and further restore knee function of patients. Generally, TKR consists of metal femoral component, metal tibial component, and UHMWPE tibial insert. TKR will fail due to various factors over time, however, this study will be focusing on failure cause by loosening. Loosening failure of TKR was mainly caused by wear debris generated during articulation motion, where UHMWPE wear was …


Evaluation Of The Diagnostic Accuracy And Utility Of A New Dengue Rapid Diagnostic Test In Malaysia, Zhuo Lin Chong Jan 2020

Evaluation Of The Diagnostic Accuracy And Utility Of A New Dengue Rapid Diagnostic Test In Malaysia, Zhuo Lin Chong

Student Works (2020-2029)

Dengue is an emerging arboviral disease endemic to many tropical countries including Malaysia. Due to its unspecific symptoms, dengue diagnosis can only be confirmed through diagnostic tests. Existing laboratory-based dengue diagnostics like enzyme linked immunosorbent assay (ELISA) is accurate in detecting dengue non-structural protein-1 (NS1), and anti-dengue immunoglobulin M (IgM) and G (IgG); but is also more complicated and time-consuming. Commercially available dengue rapid immunochromatographic test (RIT) is efficient but less sensitive. A new dengue rapid diagnostic rest (RDT) using biosensors may be both efficient and accurate in diagnosing acute dengue. This study evaluated this new dengue NS1-based RDT and …

Dielectrophoresis (DEP) is an electrical phenomenon that occurs when a polarisable particle is placed in non-uniform electrical fields, generating DEP force (FDEP) that is dependent upon the electrophysiological make-up of the particle in use. In cell cytometry studies, DEP offers the advantage of conducting various cell manipulations in vitro without the need of specific surface markers. Its drawbacks, namely the time-consuming processes involved and the inability to conduct large batch cell assays, had limited its usage. This thesis presents the work that offered solution to the said obstacles, by developing a system capable of conducting DEP experiments within a very …


Estimation Of The Product Yield And Collection Efficiency Of Peripheral Blood Stem Cell Harvesting Using Peripheral Blood Cd34[+] Cells Quantification., Habsah Aziz Jan 2010

Estimation Of The Product Yield And Collection Efficiency Of Peripheral Blood Stem Cell Harvesting Using Peripheral Blood Cd34[+] Cells Quantification., Habsah Aziz

Student Works (2010-2019)

Peripheral blood stem cells (PBSC) have been used for transplantation since the early 1990s. CD34+ has been used as a marker of hematopoietic stem cells to determine the optimal timing for PBSC harvesting. However, a wide ranges of CD34+ cells cut-off values from 8/ul to 66/ul have been used to initiate PBSC harvesting in autologous patients. We performed here a study to determine the peripheral blood CD34+ cells cut-off value for the prediction of stem cell yield of 2 x106 CD34+ cells/kg body weight patients, to study the correlation between peripheral blood CD34+ cells and stem cell yield, to study …

Student Works (2000-2009)

Sistem Maklumat Perubatan Tradisional Melayu adalah merupakan satu sistem makumat berkomputer yang dibangunkan di halaman web. Ia bertujuan untuk membantu pengguna mencapai maklumat mengenai (ubatan tradisional serta tumbuhan berubat yang) diamalkan oleh orang Melayu. Sistem ini akan menceritakan serba sedikit tentang sejarah penggunaan perubatan tradisional. Pengguna sistem juga dijangka dapat mengemukan pertanyaan dan memberi sebarang komen yang berkaitan dengan sistem. Bantuan kepada pengguna sistem tentang cara menggunakan sistem turut dipaparkan dalam pembangunan system ini nanti. Sistem ini juga membolehkan pihak pentadbir membuat pengemaskinian maklumat mengikut kesesuaian semasa dan pembaharuan. Ia adalah sejajar dengan matlamat untuk memastikan penyimpanan maklwnat yang lebih …
